Description

本発明は、コネクタに関する。 The present invention relates to a connector.

雌端子を収容する雌ハウジングと、雄端子を収容する雄ハウジングとが嵌合されることで、雌端子と雄端子とが電気的に接続される嵌合コネクタが知られている。このような嵌合コネクタでは、車両の走行時等の振動により外力が加わると、雌端子と雄端子との間で微摺動摩耗を生じる虞がある。このような微摺動摩耗により生じた摩耗粉が雌端子と雄端子との間に介在すると、雌端子と雄端子との電気接続信頼性が低下する可能性がある。 There is known a mating connector in which a female housing that accommodates a female terminal is mated with a male housing that accommodates a male terminal, thereby electrically connecting the female terminal and the male terminal. In such a mating connector, when an external force is applied due to vibrations while the vehicle is running, there is a risk that micro-friction wear will occur between the female terminal and the male terminal. If wear powder generated by such micro-friction gets between the female terminal and the male terminal, the reliability of the electrical connection between the female terminal and the male terminal may decrease.

そこで、タブ(雄端子)の移動に起因する摩耗を抑制する端子金具を提供する技術が知られている(例えば、特許文献1)。
特許文献1に記載された端子金具は、相手側端子のタブが挿入される角筒部内に設けられた弾性接触片と受け部との間で、タブを厚さ方向に挟むように構成されている。更に、角筒部の側壁に形成された弾性片がタブの側縁を幅方向に押圧することで、タブの幅方向への変位が抑制されるように構成されている。
そこで、角筒部内に挿入された相手側端子のタブは、タブの幅方向への移動に起因するタブ、弾性接触片、受け部の摩耗を抑制することができる。
In view of this, a technique is known for providing a terminal fitting that suppresses wear caused by movement of the tab (male terminal) (for example, Patent Document 1).
The terminal fitting described in Patent Document 1 is configured to sandwich the tab in the thickness direction between a resilient contact piece and a receiving part provided in a rectangular tube portion into which the tab of the mating terminal is inserted. Furthermore, the resilient piece formed on the side wall of the rectangular tube portion presses the side edge of the tab in the width direction, thereby suppressing the displacement of the tab in the width direction.
Therefore, the tab of the mating terminal inserted into the rectangular tube portion can be prevented from being worn down, on the tab, the elastic contact piece, and the receiving portion, due to movement of the tab in the width direction.

特開2009-54504号公報JP 2009-54504 A

しかしながら、上記特許文献1に記載された端子金具は、相手側端子のタブを角筒部内に挿入する際には、タブにより弾性接触片と弾性片とを同時に弾性変形させる必要があり、端子金具に相手側端子のタブを挿入する挿入力が高くなってしまう。そのため、端子金具と相手側端子を嵌合するコネクタ嵌合力が高くなり、作業性が低下するという問題がある。 However, when inserting the tab of the mating terminal in the terminal fitting described in the above Patent Document 1 into the rectangular tube portion, the tab must simultaneously elastically deform the elastic contact piece and the elastic piece, which increases the insertion force required to insert the tab of the mating terminal into the terminal fitting. This results in a problem of increased connector mating force for mating the terminal fitting with the mating terminal, reducing workability.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、コネクタ嵌合力が高くなるのを抑えつつ、端子の微摺動摩耗を抑制することができるコネクタを提供することにある。 The present invention was made in consideration of the above-mentioned circumstances, and its purpose is to provide a connector that can suppress micro-sliding wear of the terminals while preventing the connector mating force from increasing.

前述した目的を達成するために、本発明に係るコネクタは、下記を特徴としている。
端子接続部材と電線接続部材とを有して電線端末に接続された端子と、
前記端子を収容するハウジングと、を備え、
前記端子接続部材は、相手側端子のタブが挿入される角筒状の端子本体部と、前記端子本体部内に設けられて前記端子本体部を構成する側壁部との間に前記タブを挟む端子バネと、先端がバネ付勢方向と反対側に延びるように前記端子バネに形成された傾斜部と、を有し、

Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is an overall oblique view showing a mating connector 1 in which a mating connector 50 is mated with a connector 10 according to a first embodiment of the present invention, FIG. 2 is an exploded oblique view of the connector 10 shown in FIG. 1, and FIGS. 3 and 4 are an oblique view and a front view showing the terminal connection member 20 shown in FIG. 2 as viewed diagonally from below and in the front.

図1に示すように、嵌合コネクタ1は、本第1実施形態に係るコネクタ10と、相手側コネクタ50とを備えて構成されている。
本第1実施形態に係るコネクタ10は、図2に示すように、絶縁樹脂製のハウジング12と、電線60の端末に接続された雌端子である端子40とで構成された雌コネクタである。なお、以下の説明においては、相手側コネクタ50に嵌合する側(図2中、右側)をコネクタ10の前方とする。
As shown in FIG. 1 , a mating connector 1 includes a connector 10 according to the first embodiment and a mating connector 50 .
As shown in Fig. 2, the connector 10 according to the first embodiment is a female connector that includes a housing 12 made of insulating resin and terminals 40 that are female terminals connected to ends of electric wires 60. In the following description, the side that mates with a mating connector 50 (the right side in Fig. 2) is defined as the front of the connector 10.

コネクタ10のハウジング12には、3つの端子40をそれぞれ収容する3つの端子収容室18が形成されている。端子収容室18内には、後方から挿入された端子40の端子接続部材20を抜け止めする可撓係止片15が設けられている(図6、参照)。ハウジング12の外周面には、ロックアーム16を有するロック部14が設けられている。 The housing 12 of the connector 10 is formed with three terminal accommodating chambers 18 that respectively accommodate three terminals 40. A flexible locking piece 15 is provided in the terminal accommodating chamber 18 to prevent the terminal connection member 20 of the terminal 40 inserted from the rear from coming loose (see FIG. 6). A locking portion 14 having a locking arm 16 is provided on the outer circumferential surface of the housing 12.

端子40は、図2に示すように、端子接続部材20と電線接続部材30の2部品で構成されている。
端子接続部材20は、図3及び図4に示すように、雄端子である相手側端子70のタブ77が挿入される角筒状の端子本体部22と、端子本体部22内に設けられた端子バネ25と、を有する。端子本体部22は、外観が挿入方向に長く扁平な直方体形状とされている。
As shown in FIG. 2 , the terminal 40 is composed of two parts, a terminal connecting member 20 and an electric wire connecting member 30 .
3 and 4, the terminal connection member 20 has a terminal body 22 having a rectangular tube shape into which the tab 77 of the mating terminal 70, which is a male terminal, is inserted, and a terminal spring 25 provided within the terminal body 22. The terminal body 22 has an appearance of a flat rectangular parallelepiped that is elongated in the insertion direction.

端子バネ25は、端子本体部22を構成する側壁部である上壁22bとの間に相手側端子70のタブ77を弾性的に挟むことができる。端子バネ25は、端子本体部22における側壁部である底壁22aの前端より折り返されて形成されている(図6、参照)。端子バネ25は、先端がバネ付勢方向と反対側(底壁22a側)に延びるように端子バネ25に形成された傾斜部26を有する。傾斜部26の先端は、底壁22a側に凸状の湾曲部となっている。 The terminal spring 25 can elastically pinch the tab 77 of the mating terminal 70 between itself and the upper wall 22b, which is a side wall that constitutes the terminal body 22. The terminal spring 25 is formed by folding back from the front end of the bottom wall 22a, which is a side wall of the terminal body 22 (see FIG. 6). The terminal spring 25 has an inclined portion 26 formed on the terminal spring 25 so that its tip extends in the opposite direction to the spring biasing direction (toward the bottom wall 22a). The tip of the inclined portion 26 is curved in a convex shape toward the bottom wall 22a.

端子バネ25に対向する上壁22bには、内方へ突出する矩形状の接触凸部27が形成されている。接触凸部27の突出面と、端子バネ25が弾性変位していない状態におけるバネ付勢方向の先端面との間における間隔は、相手側端子70のタブ77の厚さ寸法よりも小さい寸法に設定されている。端子本体部22の底壁22aには、ハウジング12の可撓係止片15に抜け止め係止される係止穴23と、電線接続部材30に設けられた係合孔Yに係合して抜け止め係止する係合突起Xとが形成されている。 A rectangular contact protrusion 27 that protrudes inward is formed on the upper wall 22b facing the terminal spring 25. The distance between the protruding surface of the contact protrusion 27 and the tip surface in the spring biasing direction when the terminal spring 25 is not elastically displaced is set to a dimension smaller than the thickness dimension of the tab 77 of the mating terminal 70. The bottom wall 22a of the terminal body 22 is formed with a locking hole 23 that is locked to the flexible locking piece 15 of the housing 12 to prevent it from coming off, and an engagement protrusion X that engages with an engagement hole Y provided in the electric wire connection member 30 to lock it in place.

電線接続部材30は、図2に示すように、電線60の端末に接続される電線接続部35と、電線接続部35の先端に連設されて端子本体部22内に挿入される挿入片37と、挿入片37の先端部に設けられた押圧突起39と、を有する。
電線接続部35は、電線60の端末に露出した導体62を圧着する導体圧着部31と、電線60を被覆64の上から固定する被覆圧着部33と、を有する。
挿入片37は、導体圧着部31の底壁先端縁から前方に向かって突出しており、先端部に形成された押圧突起39は上方に突出している。また、導体圧着部31の底壁には、端子本体部22の係合突起Xに抜け止め係止される係合孔Yが設けられている。
As shown in FIG. 2 , the wire connection member 30 has a wire connection portion 35 connected to the end of the wire 60, an insertion piece 37 connected to the tip of the wire connection portion 35 and inserted into the terminal body portion 22, and a pressing protrusion 39 provided at the tip of the insertion piece 37.
The electric wire connection portion 35 has a conductor crimping portion 31 that crimps the conductor 62 exposed at the end of the electric wire 60 , and a coating crimping portion 33 that fixes the electric wire 60 from above the coating 64 .
The insertion piece 37 protrudes forward from the tip edge of the bottom wall of the conductor crimping portion 31, and a pressing protrusion 39 formed at the tip protrudes upward. The bottom wall of the conductor crimping portion 31 is provided with an engagement hole Y that is engaged with the engagement protrusion X of the terminal body 22 to prevent it from coming off.

押圧突起39は、端子本体部22内において上壁22bに対して対向する方向に突出している。そして、押圧突起39は、挿入片37が後方開口24から端子本体部22内に挿入された際には、端子バネ25の傾斜部26に抜け止め係止されると共に、傾斜部26をバネ付勢方向へ押圧する。
そこで、端子接続部材20と電線接続部材30とは、挿入片37が端子本体部22内に挿入されることで、一体的に連結されると共に電気的に接続されて端子40を構成することができる(図9及び図10、参照)。
The pressing protrusion 39 protrudes in a direction facing the upper wall 22b inside the terminal body 22. When the insertion piece 37 is inserted into the terminal body 22 from the rear opening 24, the pressing protrusion 39 is locked in the inclined portion 26 of the terminal spring 25 to prevent it from coming out, and presses the inclined portion 26 in the spring biasing direction.
Therefore, the terminal connection member 20 and the wire connection member 30 can be integrally linked and electrically connected to form a terminal 40 by inserting the insertion piece 37 into the terminal main body portion 22 (see Figures 9 and 10).

図5は図1に示した相手側コネクタ50の分解斜視図である。
相手側コネクタ50は、図5に示すように、絶縁樹脂製のハウジング52と、電線80の端末に接続された雄端子である相手側端子70とで構成された雄コネクタである。なお、以下の説明においては、コネクタ10に嵌合する側(図5中、左側)を相手側コネクタ50の前方とする。

5, the mating connector 50 is a male connector that includes an insulating resin housing 52 and a mating terminal 70 that is a male terminal connected to an end of an electric wire 80. In the following description, the side that fits into the connector 10 (the left side in FIG. 5) is referred to as the front of the mating connector 50.

ハウジング52の本体部53には、3つの相手側端子70をそれぞれ収容する3つの端子収容室56が形成されている(図6、参照)。端子収容室56内には、後方から挿入された相手側端子70を抜け止めする可撓係止片57が設けられている(図6、参照)。
本体部53の前方には、コネクタ10のハウジング12が嵌合される嵌合空間58を画成するフード部55が設けられている。フード部55の外周面には、ロックアーム16に係止される被ロック突起(図示せず)を有する被ロック部54が設けられている。
The main body 53 of the housing 52 is formed with three terminal accommodating chambers 56 for accommodating three mating terminals 70, respectively (see FIG. 6). The terminal accommodating chambers 56 are provided with flexible locking pieces 57 for preventing the mating terminals 70 inserted from the rear from coming out (see FIG. 6).
A hood portion 55 is provided in front of the main body portion 53, which defines a fitting space 58 into which the housing 12 of the connector 10 is fitted. A locked portion 54 having a locking projection (not shown) that is engaged with the locking arm 16 is provided on the outer circumferential surface of the hood portion 55.

相手側端子70は、図5に示すように、電線80の端末に接続される電線接続部75と、電線接続部75の先端に連設されて端子40の端子本体部22内に挿入されるタブ77と、を有する。
電線接続部75は、電線80の端末に露出した導体82を圧着する導体圧着部71と、電線80を被覆84の上から固定する被覆圧着部73と、を有する。タブ77は、外観が挿入方向に長い矩形の板形状とされている。
As shown in FIG. 5 , the mating terminal 70 has a wire connection portion 75 that is connected to the end of the electric wire 80, and a tab 77 that is connected to the tip of the wire connection portion 75 and inserted into the terminal body portion 22 of the terminal 40.
The electric wire connection portion 75 has a conductor crimping portion 71 that crimps the conductor 82 exposed at the end of the electric wire 80, and a coating crimping portion 73 that fixes the electric wire 80 from above the coating 84. The tab 77 has an external appearance of a rectangular plate shape that is long in the insertion direction.

コネクタアッセンブリ10Aと相手側コネクタ50との嵌合過程では、ハウジング12の端子挿入口13から端子収容室18に挿入された相手側端子70のタブ77が、端子本体部22内に挿入され、端子バネ25を弾性変形させる。 During the mating process between the connector assembly 10A and the mating connector 50, the tab 77 of the mating terminal 70 inserted into the terminal accommodating chamber 18 from the terminal insertion port 13 of the housing 12 is inserted into the terminal body 22, causing the terminal spring 25 to elastically deform.

図7に示したように、コネクタアッセンブリ10Aと相手側コネクタ50との嵌合が完了すると、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20の端子バネ25が接触する。そこで、相手側端子70は、タブ77が端子接続部材20における端子バネ25と接触凸部27とに挟持される状態で、端子接続部材20に電気的に接続される。 As shown in FIG. 7, when the connector assembly 10A and the mating connector 50 are completely mated, the restoring force caused by the elastic deformation of the terminal spring 25 brings the tab 77 of the mating terminal 70 into contact with the terminal spring 25 of the terminal connection member 20. The mating terminal 70 is then electrically connected to the terminal connection member 20 with the tab 77 sandwiched between the terminal spring 25 and the contact protrusion 27 of the terminal connection member 20.

コネクタアッセンブリ10Aと相手側コネクタ50とが嵌合されると、相手側ハウジング52の被ロック突起(図示せず)がハウジング12のロックアーム16に係止され、相手側ハウジング52とハウジング12との嵌合状態が維持される。 When the connector assembly 10A and the mating connector 50 are mated, the locking projection (not shown) of the mating housing 52 is engaged with the locking arm 16 of the housing 12, maintaining the mating state between the mating housing 52 and the housing 12.

次に、図7に示すように、電線60の端末に接続された電線接続部材30が、ハウジング12の端子収容室18に挿入され、コネクタアッセンブリ10Aと相手側コネクタ50とが嵌合された嵌合コネクタアッセンブリ1Aの端子接続部材20に組み付けられる。 Next, as shown in FIG. 7, the wire connection member 30 connected to the end of the wire 60 is inserted into the terminal accommodating chamber 18 of the housing 12 and is assembled to the terminal connection member 20 of the mating connector assembly 1A in which the connector assembly 10A and the mating connector 50 are mated.

端子接続部材20と電線接続部材30との結合過程では、図8に示すように、後方開口24から端子本体部22内に挿入された挿入片37の押圧突起39が、端子バネ25の先端に形成された湾曲部28に当接する。 During the process of joining the terminal connection member 20 and the electric wire connection member 30, as shown in FIG. 8, the pressing protrusion 39 of the insertion piece 37 inserted into the terminal body 22 from the rear opening 24 abuts against the curved portion 28 formed at the tip of the terminal spring 25.

そして、電線接続部材30の挿入片37が端子本体部22内にさらに挿入されることで、押圧突起39は端子バネ25の湾曲部28を押し上げながら通過する。そして、図9に示すように、端子接続部材20と電線接続部材30との結合が完了すると、押圧突起39は端子バネ25の傾斜部26に達する。このように、端子接続部材20と電線接続部材30とは、互いの結合が完了することで、一体的に連結されると共に電気的に接続されて端子40になる。 Then, as the insertion piece 37 of the electric wire connection member 30 is further inserted into the terminal body 22, the pressing protrusion 39 passes through while pushing up the curved portion 28 of the terminal spring 25. Then, as shown in FIG. 9, when the connection between the terminal connection member 20 and the electric wire connection member 30 is completed, the pressing protrusion 39 reaches the inclined portion 26 of the terminal spring 25. In this way, when the connection between the terminal connection member 20 and the electric wire connection member 30 is completed, the terminal connection member 20 and the electric wire connection member 30 are integrally linked and electrically connected to form the terminal 40.

尚、電線接続部30の挿入片37が端子本体部22内に挿入された状態において、電線接続部30と端子本体部22との間には、係合機構が設けられている方が望ましい。係合機構としては、例えば図9中に示したように、端子本体部22の底壁22aに係合突起Xが設けられ(図4、参照)、導体圧着部31の底壁に係合孔Yが設けられる(図2、参照)。係合突起Xと係合孔Yとの係合により、電線接続部30と端子本体部22とが、より一体的に連結された状態を維持できる。 When the insertion piece 37 of the electric wire connection part 30 is inserted into the terminal body part 22, it is preferable to provide an engagement mechanism between the electric wire connection part 30 and the terminal body part 22. As an engagement mechanism, for example, as shown in FIG. 9, an engagement protrusion X is provided on the bottom wall 22a of the terminal body part 22 (see FIG. 4), and an engagement hole Y is provided on the bottom wall of the conductor crimping part 31 (see FIG. 2). The engagement between the engagement protrusion X and the engagement hole Y allows the electric wire connection part 30 and the terminal body part 22 to be maintained in a more integrally connected state.

端子接続部材20と電線接続部材30との結合が完了して端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。そして、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とにより、相手側端子70のタブ77と端子接続部材20の端子バネ25とが接触する。
そこで、相手側端子70は、タブ77が端子接続部材20における端子バネ25と接触凸部27とに挟持される状態で、端子40に電気的に接続される。
When the connection between the terminal connection member 20 and the electric wire connection member 30 is completed, the pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25. Then, due to the restoring force due to the elastic deformation of the terminal spring 25 and the pressing force of the pressing protrusion 39 pressing the inclined portion 26 of the terminal spring 25, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20 come into contact with each other.
Thus, the mating terminal 70 is electrically connected to the terminal 40 with the tab 77 sandwiched between the terminal spring 25 and the contact protrusion 27 of the terminal connecting member 20 .

図10は、本第1実施形態に係るコネクタ10と相手側コネクタ50とが電気的に接続された状態を示す嵌合コネクタ1の縦断面図である。
図10に示すように、嵌合コネクタアッセンブリ1Aは、3つの電線接続部材30が端子接続部材20にそれぞれ組み付けられることで、嵌合コネクタ1が組み立てられたことになる。
FIG. 10 is a vertical cross-sectional view of the mating connector 1, showing a state in which the connector 10 according to the first embodiment and a mating connector 50 are electrically connected.
As shown in FIG. 10, the mating connector assembly 1A is formed by assembling three electric wire connecting members 30 to the terminal connecting members 20, respectively, to form the mating connector 1.

なお、嵌合コネクタ1は、被ロック突起(図示せず)とロックアーム16のロックにより、相手側コネクタ50とコネクタ10との嵌合状態が維持されている。嵌合コネクタ1の離脱は、ロックアーム16を操作して被ロック突起とロックアーム16のロックを解除し、相手側コネクタ50の嵌合空間58からコネクタ10を引き抜くことにより行われる。 The mating connector 1 maintains the mated state between the mating connector 50 and the connector 10 by locking the locking protrusion (not shown) and the locking arm 16. The mating connector 1 can be removed by operating the locking arm 16 to release the lock between the locking protrusion and the locking arm 16, and then pulling out the connector 10 from the mating space 58 of the mating connector 50.

次に、本第1実施形態に係るコネクタ10の作用効果を説明する。
上述したように、本第1実施形態に係るコネクタ10によれば、ハウジング12の端子収容室18に収容される端子40は、図2に示したように、端子接続部材20と電線接続部材30の2部品で構成されている。
Next, the effects of the connector 10 according to the first embodiment will be described.
As described above, according to the connector 10 of the first embodiment, the terminal 40 accommodated in the terminal accommodating chamber 18 of the housing 12 is composed of two parts, the terminal connecting member 20 and the wire connecting member 30, as shown in Figure 2.

そこで、先ずは3つの端子接続部材20をハウジング12の端子収容室18にそれぞれ挿入して可撓係止片15に抜け止め係止させることにより、コネクタ10のコネクタアッセンブリ10Aが組み立てられる。 First, the three terminal connection members 20 are inserted into the terminal accommodating chambers 18 of the housing 12 and locked into the flexible locking pieces 15 to prevent them from coming loose, thereby assembling the connector assembly 10A of the connector 10.

次に、図6に示したように、コネクタアッセンブリ10Aが、相手側コネクタ50に嵌合される。この際、相手側端子70のタブ77が、端子接続部材20の端子本体部22内に挿入されて端子バネ25を弾性変形させる。そこで、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20の端子バネ25が接触する。 Next, as shown in FIG. 6, the connector assembly 10A is fitted into the mating connector 50. At this time, the tab 77 of the mating terminal 70 is inserted into the terminal body 22 of the terminal connection member 20, elastically deforming the terminal spring 25. Then, due to the restoring force caused by the elastic deformation of the terminal spring 25, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20 come into contact.

即ち、端子接続部材20の端子本体部22内に挿入される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力だけが作用し、端子接続部材20の端子本体部22内に相手側端子70のタブ77を挿入する挿入力が高くなるのを抑えることができる。そのため、コネクタ10と相手側コネクタ50とを嵌合するコネクタ嵌合力も、高くなるのを抑えることができる。 In other words, only the restoring force due to the elastic deformation of the terminal spring 25 acts on the tab 77 of the mating terminal 70 inserted into the terminal body 22 of the terminal connection member 20, and the insertion force for inserting the tab 77 of the mating terminal 70 into the terminal body 22 of the terminal connection member 20 can be prevented from becoming too high. Therefore, the connector mating force for mating the connector 10 and the mating connector 50 can also be prevented from becoming too high.

そして、図7に示したように、電線60の端末に接続された電線接続部材30が、コネクタアッセンブリ10Aと相手側コネクタ50とが嵌合された嵌合コネクタアッセンブリ1Aの端子接続部材20に組み付けられる。この際、電線接続部材30の挿入片37が端子接続部材20の端子本体部22内に挿入され、端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。 Then, as shown in FIG. 7, the electric wire connection member 30 connected to the end of the electric wire 60 is assembled to the terminal connection member 20 of the mating connector assembly 1A in which the connector assembly 10A and the mating connector 50 are mated. At this time, the insertion piece 37 of the electric wire connection member 30 is inserted into the terminal body 22 of the terminal connection member 20, and the pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25.

即ち、端子接続部材20における端子バネ25と接触凸部27とに挟持される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とが作用し、相手側端子70のタブ77と端子接続部材20の端子バネ25とは強く接触することができる。 In other words, the tab 77 of the mating terminal 70, which is sandwiched between the terminal spring 25 and the contact protrusion 27 of the terminal connection member 20, is subjected to the restoring force due to the elastic deformation of the terminal spring 25 and the pressing force of the pressing protrusion 39 pressing the inclined portion 26 of the terminal spring 25, so that the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20 can come into strong contact.

そこで、3つの電線接続部材30が嵌合コネクタアッセンブリ1Aの端子接続部材20にそれぞれ接続されて組み立てられた嵌合コネクタ1は、端子40と相手側端子70とのガタ付きによる端子バネ25とタブ77との間での微摺動摩耗が抑制される。この微摺動摩耗の抑制により、微摺動摩耗により生じる摩耗粉が端子バネ25とタブ77との間に介在してしまうことが防止される。このため、端子40と相手側端子70の電気接続信頼性が低下することを抑制できる。
従って、本第1実施形態に係るコネクタ10によれば、コネクタ嵌合力が高くなるのを抑えつつ、端子40の微摺動摩耗を抑制することができる。
Therefore, in the mating connector 1 assembled by connecting the three electric wire connecting members 30 to the terminal connecting members 20 of the mating connector assembly 1A, micro-sliding wear between the terminal spring 25 and the tab 77 caused by rattle between the terminal 40 and the mating terminal 70 is suppressed. This suppression of micro-sliding wear prevents wear powder generated by micro-sliding wear from being interposed between the terminal spring 25 and the tab 77. This makes it possible to suppress a decrease in the reliability of the electrical connection between the terminal 40 and the mating terminal 70.
Therefore, according to the connector 10 of the first embodiment, it is possible to suppress micro-sliding wear of the terminals 40 while preventing the connector mating force from becoming too high.

図11は本発明の第2実施形態に係るコネクタ110のコネクタアッセンブリ110Aに、電線接続部材30が挿入される状態を示す縦断面図、図12は図11に示したコネクタ110と相手側コネクタ50との嵌合途中状態を示す縦断面図である。なお、本第2実施形態に係るコネクタ110は、端子40に代えて端子40Aが用いられた以外は上記第1実施形態のコネクタ10と同様の構成であるので、同様の構成部材には同符号を付して詳細な説明を省略する。 Figure 11 is a vertical cross-sectional view showing the state in which the electric wire connection member 30 is inserted into the connector assembly 110A of the connector 110 according to the second embodiment of the present invention, and Figure 12 is a vertical cross-sectional view showing the connector 110 shown in Figure 11 and the mating connector 50 in the middle of mating. Note that the connector 110 according to this second embodiment has the same configuration as the connector 10 of the first embodiment described above, except that the terminal 40A is used instead of the terminal 40, so similar components are given the same reference numerals and detailed description will be omitted.

本第2実施形態に係るコネクタ110の端子40Aは、図11に示すように、端子接続部材20Aと電線接続部材30の2部品で構成されている。
端子接続部材20Aは、端子本体部22内に設けられた端子バネ25と、抜け止め片21とを有する。そして、端子接続部材20Aがハウジング12の端子収容室18に収容されることで、コネクタ110のコネクタアッセンブリ110Aが構成される。
A terminal 40A of a connector 110 according to the second embodiment is composed of two parts, a terminal connecting member 20A and an electric wire connecting member 30, as shown in FIG.
The terminal connecting member 20A has a terminal spring 25 provided in the terminal body 22, and a retaining piece 21. The terminal connecting member 20A is accommodated in the terminal accommodating chamber 18 of the housing 12, whereby a connector assembly 110A of the connector 110 is formed.

抜け止め片21は、端子バネ25に対向する上壁22bに切り起こし形成されて先端が内方へ突出する矩形状の突出片である。抜け止め片21は、端子接続部材20Aの端子本体部22内に電線接続部材30の挿入片37が挿入された際、挿入片37の押圧突起39を端子バネ25の湾曲部28より後方位置で抜け止め係止する。 The retaining piece 21 is a rectangular protruding piece that is cut and formed on the upper wall 22b facing the terminal spring 25 and has a tip that protrudes inward. When the insertion piece 37 of the electric wire connection member 30 is inserted into the terminal body portion 22 of the terminal connection member 20A, the retaining piece 21 locks the pressing protrusion 39 of the insertion piece 37 at a position rearward of the curved portion 28 of the terminal spring 25 to prevent it from falling out.

そこで、図12に示すように、コネクタアッセンブリ110Aの端子収容室18に挿入されて端子接続部材20Aの抜け止め片21によって挿入片37の押圧突起39が抜け止め係止された電線接続部材30は、端子接続部材20Aに対して挿入方向に相対的なスライドが可能な仮組み付け状態で端子40Aを構成することができる。 As shown in FIG. 12, the wire connection member 30 is inserted into the terminal receiving chamber 18 of the connector assembly 110A and the pressing protrusion 39 of the insertion piece 37 is locked in place by the retaining piece 21 of the terminal connection member 20A, forming a terminal 40A in a provisionally assembled state in which it can slide relative to the terminal connection member 20A in the insertion direction.

即ち、電線接続部材30がコネクタアッセンブリ110Aの端子収容室18に挿入されて、仮組み付け状態として端子接続部材20Aに組み付けられることで、コネクタアッセンブリ110Aは端子40Aを端子収容室18に収容したコネクタ110となる。 That is, the electric wire connection member 30 is inserted into the terminal receiving chamber 18 of the connector assembly 110A and assembled to the terminal connection member 20A in a provisionally assembled state, so that the connector assembly 110A becomes a connector 110 with the terminal 40A received in the terminal receiving chamber 18.

次に、図12~図14を参照しながら上記コネクタ110と相手側コネクタ50とを嵌合する嵌合コネクタ101の組立手順を説明する。
図13は図12に示した電線接続部材30の挿入片37が端子接続部材20Aの抜け止め片21により抜け止め係止された状態を示す要部拡大断面図、図14は図13に示した電線接続部材30の挿入片37が端子接続部材20Aの端子バネ25により抜け止め係止された状態を示す要部拡大断面図である。
Next, a procedure for assembling the mating connector 101 in which the connector 110 and the mating connector 50 are mated will be described with reference to FIGS.
Figure 13 is an enlarged cross-sectional view of a key portion showing the state in which the insertion piece 37 of the wire connection member 30 shown in Figure 12 is locked in place by the anti-slip piece 21 of the terminal connection member 20A, and Figure 14 is an enlarged cross-sectional view of a key portion showing the state in which the insertion piece 37 of the wire connection member 30 shown in Figure 13 is locked in place by the terminal spring 25 of the terminal connection member 20A.

先ず、図11に示したように、電線60の端末に接続された電線接続部材30が、コネクタアッセンブリ110Aの端子収容室18にそれぞれ挿入される。そして、挿入片37の押圧突起39が端子接続部材20Aの抜け止め片21を押し上げながら通過し、押圧突起39は端子バネ25の湾曲部28と抜け止め片21との間まで挿入される。 First, as shown in FIG. 11, the electric wire connection members 30 connected to the ends of the electric wires 60 are inserted into the terminal receiving chambers 18 of the connector assembly 110A. Then, the pressing protrusions 39 of the insertion pieces 37 pass through while pushing up the retaining pieces 21 of the terminal connection member 20A, and the pressing protrusions 39 are inserted between the curved portions 28 of the terminal springs 25 and the retaining pieces 21.

すると、端子接続部材20Aの抜け止め片21に挿入片37の押圧突起39が抜け止め係止された電線接続部材30は、端子接続部材20Aに対して挿入方向に相対的なスライドが可能な仮組み付け状態となった端子40Aを構成する。即ち、コネクタアッセンブリ110Aの端子収容室18に収容された端子40Aは、電線接続部材30が端子接続部材20Aに対して仮組み付け状態とされたコネクタ110を構成する。この電線接続部材30が端子接続部材20Aに対して仮組み付け状態とされたコネクタ110は、運搬などにより取り扱う際、電線接続部材30と端子接続部材20Aとが不用意に分離してしまうことがない。 The electric wire connection member 30, in which the pressing protrusion 39 of the insertion piece 37 is locked in the retaining piece 21 of the terminal connection member 20A, constitutes a terminal 40A in a provisionally assembled state in which it can slide relatively in the insertion direction relative to the terminal connection member 20A. That is, the terminal 40A accommodated in the terminal accommodating chamber 18 of the connector assembly 110A constitutes a connector 110 in which the electric wire connection member 30 is provisionally assembled to the terminal connection member 20A. The connector 110 in which the electric wire connection member 30 is provisionally assembled to the terminal connection member 20A does not accidentally separate from the electric wire connection member 30 and the terminal connection member 20A when it is handled, such as during transportation.

次に、図12に示すように、相手側ハウジング52の嵌合空間58内にコネクタ110のハウジング12が嵌入される。この際、電線60の端末に接続された電線接続部材30は、挿入片37の押圧突起39が端子接続部材20Aの抜け止め片21に抜け止め係止されている。そこで、端子40Aの電線接続部材30は、コネクタ110から不用意に抜け落ちてしまうことがなく、コネクタの嵌合作業性がよい。 Next, as shown in FIG. 12, the housing 12 of the connector 110 is fitted into the mating space 58 of the mating housing 52. At this time, the wire connection member 30 connected to the end of the electric wire 60 has the pressing protrusion 39 of the insertion piece 37 locked into the retaining piece 21 of the terminal connection member 20A. Therefore, the wire connection member 30 of the terminal 40A does not accidentally fall out of the connector 110, and the connector can be easily fitted.

コネクタ110と相手側コネクタ50との嵌合過程では、ハウジング12の端子挿入口13から端子収容室18に挿入された相手側端子70のタブ77が、端子本体部22内に挿入され、端子バネ25を弾性変形させる。そして、図13に示したように、コネクタ110と相手側コネクタ50との嵌合が完了すると、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20Aの端子バネ25が接触する。 During the mating process between the connector 110 and the mating connector 50, the tab 77 of the mating terminal 70 inserted into the terminal accommodating chamber 18 from the terminal insertion port 13 of the housing 12 is inserted into the terminal body 22, elastically deforming the terminal spring 25. Then, as shown in FIG. 13, when the mating between the connector 110 and the mating connector 50 is completed, the restoring force caused by the elastic deformation of the terminal spring 25 brings the tab 77 of the mating terminal 70 into contact with the terminal spring 25 of the terminal connection member 20A.

次に、電線接続部材30の挿入片37が端子本体部22内にさらに挿入されることで、押圧突起39は端子バネ25の湾曲部28を押し上げながら通過する。そして、図14に示すように、端子接続部材20Aと電線接続部材30との結合が完了すると、押圧突起39は端子バネ25の傾斜部26に達する。このように、端子接続部材20Aと電線接続部材30とは、互いの結合が完了することで、一体的に連結されると共に電気的に接続されて本組み付け状態の端子40Aになる。 Next, the insertion piece 37 of the electric wire connection member 30 is further inserted into the terminal body 22, so that the pressing protrusion 39 passes through while pushing up the curved portion 28 of the terminal spring 25. Then, as shown in FIG. 14, when the connection between the terminal connection member 20A and the electric wire connection member 30 is completed, the pressing protrusion 39 reaches the inclined portion 26 of the terminal spring 25. In this way, when the connection between the terminal connection member 20A and the electric wire connection member 30 is completed, they are integrally linked and electrically connected to become the terminal 40A in the fully assembled state.

端子接続部材20Aと電線接続部材30との結合が完了して端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。そして、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とにより、相手側端子70のタブ77と端子接続部材20Aの端子バネ25とが接触する。
そこで、相手側端子70は、タブ77が端子接続部材20Aにおける端子バネ25と接触凸部27とに挟持される状態で、端子40Aに電気的に接続される。
When the connection between the terminal connection member 20A and the electric wire connection member 30 is completed, the pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25. Then, due to the restoring force due to the elastic deformation of the terminal spring 25 and the pressing force of the pressing protrusion 39 pressing the inclined portion 26 of the terminal spring 25, the tab 77 of the mating terminal 70 comes into contact with the terminal spring 25 of the terminal connection member 20A.
Thus, the mating terminal 70 is electrically connected to the terminal 40A with the tab 77 being clamped between the terminal spring 25 and the contact protrusion 27 of the terminal connecting member 20A.

次に、本第2実施形態に係るコネクタ110の作用効果を説明する。
上述したように、本第2実施形態に係るコネクタ110によれば、ハウジング12の端子収容室18に収容される端子40Aは、図11に示したように、端子接続部材20Aと電線接続部材30の2部品で構成されている。
Next, the effects of the connector 110 according to the second embodiment will be described.
As described above, according to the connector 110 of the second embodiment, the terminal 40A accommodated in the terminal accommodating chamber 18 of the housing 12 is composed of two parts, a terminal connecting member 20A and a wire connecting member 30, as shown in Figure 11.

そこで、先ずは3つの端子接続部材20Aをハウジング12の端子収容室18にそれぞれ挿入して可撓係止片15に抜け止め係止させることにより、コネクタ110のコネクタアッセンブリ110Aが組み立てられる。 First, the three terminal connection members 20A are inserted into the terminal accommodating chambers 18 of the housing 12 and locked into the flexible locking pieces 15 to prevent them from coming loose, thereby assembling the connector assembly 110A of the connector 110.

次に、電線60の端末に接続された電線接続部材30が、コネクタアッセンブリ110Aの端子収容室18にそれぞれ挿入される。この際、挿入片37の押圧突起39が、端子接続部材20Aにおける端子バネ25の湾曲部28と抜け止め片21との間まで挿入される。 Next, the electric wire connection members 30 connected to the ends of the electric wires 60 are inserted into the terminal accommodating chambers 18 of the connector assembly 110A. At this time, the pressing protrusions 39 of the insertion pieces 37 are inserted between the curved portions 28 of the terminal springs 25 in the terminal connection member 20A and the retaining pieces 21.

そして、電線接続部材30が端子接続部材20Aに対して挿入方向に相対的なスライドが可能な仮組み付け状態となった端子40Aが構成される。即ち、端子40Aがコネクタアッセンブリ110Aの端子収容室18に収容されることにより、電線接続部材30が端子接続部材20Aに対して仮組み付け状態とされたコネクタ110が組み立てられる。 Then, the terminal 40A is formed in a provisionally assembled state in which the electric wire connection member 30 can slide relative to the terminal connection member 20A in the insertion direction. That is, the terminal 40A is accommodated in the terminal accommodating chamber 18 of the connector assembly 110A, and the connector 110 is assembled in which the electric wire connection member 30 is provisionally assembled to the terminal connection member 20A.

そこで、端子40Aの電線接続部材30が端子接続部材20Aに対して仮組み付け状態とされたコネクタ110は、運搬などにより取り扱う際、電線接続部材30と端子接続部材20Aとが不用意に分離してしまうのを防止できる。 Therefore, the connector 110 in which the electric wire connection member 30 of the terminal 40A is temporarily assembled to the terminal connection member 20A can prevent the electric wire connection member 30 and the terminal connection member 20A from accidentally separating when handled during transportation, etc.

次に、図12に示したように、コネクタ110が、相手側コネクタ50に嵌合される。この際、相手側端子70のタブ77が、端子接続部材20Aの端子本体部22内に挿入されて端子バネ25を弾性変形させる。そこで、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20Aの端子バネ25が接触する。 Next, as shown in FIG. 12, the connector 110 is fitted into the mating connector 50. At this time, the tab 77 of the mating terminal 70 is inserted into the terminal body 22 of the terminal connection member 20A, elastically deforming the terminal spring 25. Then, due to the restoring force caused by the elastic deformation of the terminal spring 25, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20A come into contact.

即ち、図13に示したように、端子接続部材20Aの端子本体部22内に挿入される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力だけが作用し、端子接続部材20Aの端子本体部22内に相手側端子70のタブ77を挿入する挿入力が高くなるのを抑えることができる。そのため、コネクタ110と相手側コネクタ50とを嵌合するコネクタ嵌合力も、高くなるのを抑えることができる。 That is, as shown in FIG. 13, only the restoring force due to the elastic deformation of the terminal spring 25 acts on the tab 77 of the mating terminal 70 inserted into the terminal body 22 of the terminal connection member 20A, and the insertion force for inserting the tab 77 of the mating terminal 70 into the terminal body 22 of the terminal connection member 20A can be prevented from becoming too high. Therefore, the connector mating force for mating the connector 110 and the mating connector 50 can also be prevented from becoming too high.

さらに、コネクタ110が相手側コネクタ50に嵌合される際、電線60の端末に接続された電線接続部材30は、挿入片37の押圧突起39が端子接続部材20Aの抜け止め片21に抜け止め係止されている。そこで、端子40Aの電線接続部材30は、コネクタ嵌合作業中にコネクタ110から不用意に抜け落ちてしまうことがなく、コネクタの嵌合作業性がよい。 Furthermore, when the connector 110 is mated with the mating connector 50, the wire connection member 30 connected to the end of the electric wire 60 has the pressing protrusion 39 of the insertion piece 37 locked in place by the retaining piece 21 of the terminal connection member 20A. Therefore, the wire connection member 30 of the terminal 40A does not inadvertently fall out of the connector 110 during the connector mating operation, improving the ease of mating the connector.

そして、電線接続部材30の挿入片37が端子本体部22内にさらに挿入されることで、押圧突起39は端子バネ25の湾曲部28を押し上げながら通過する。そして、図14に示すように、端子接続部材20Aと電線接続部材30との結合が完了すると、押圧突起39は端子バネ25の傾斜部26に達する。端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。 Then, as the insertion piece 37 of the electric wire connection member 30 is further inserted into the terminal body 22, the pressing protrusion 39 passes through while pushing up the curved portion 28 of the terminal spring 25. Then, as shown in FIG. 14, when the connection between the terminal connection member 20A and the electric wire connection member 30 is completed, the pressing protrusion 39 reaches the inclined portion 26 of the terminal spring 25. The pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25.

即ち、端子接続部材20Aにおける端子バネ25と接触凸部27とに挟持される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とが作用し、相手側端子70のタブ77と端子接続部材20Aの端子バネ25とは強く接触することができる。 In other words, the tab 77 of the mating terminal 70, which is sandwiched between the terminal spring 25 and the contact protrusion 27 of the terminal connection member 20A, is subjected to the restoring force due to the elastic deformation of the terminal spring 25 and the pressing force of the pressing protrusion 39 pressing the inclined portion 26 of the terminal spring 25, so that the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20A can come into strong contact.

そこで、3つの電線接続部材30がコネクタ110の端子接続部材20Aにそれぞれ接続されて組み立てられた嵌合コネクタ101は、端子40Aと相手側端子70とのガタ付きによる端子バネ25とタブ77との間での微摺動摩耗が抑制される。この微摺動摩耗の抑制により、微摺動摩耗により生じる摩耗粉が端子バネ25とタブ77との間に介在してしまうことが防止される。このため、端子40Aと相手側端子70の電気接続信頼性が低下することを抑制できる。
従って、本第2実施形態に係るコネクタ110によれば、コネクタ嵌合力が高くなるのを抑えつつ、端子40Aの微摺動摩耗を抑制することができる。
Therefore, in the mating connector 101 assembled by connecting the three electric wire connecting members 30 to the terminal connecting members 20A of the connector 110, micro-sliding wear between the terminal spring 25 and the tab 77 caused by rattle between the terminal 40A and the mating terminal 70 is suppressed. This suppression of micro-sliding wear prevents wear powder generated by micro-sliding wear from being interposed between the terminal spring 25 and the tab 77. As a result, it is possible to suppress a decrease in the reliability of the electrical connection between the terminal 40A and the mating terminal 70.
Therefore, according to the connector 110 according to the second embodiment, it is possible to suppress micro-sliding wear of the terminals 40A while preventing the connector fitting force from becoming too high.

図15は本発明の第3実施形態に係るコネクタ210のコネクタアッセンブリ210Aに、電線接続部材30が挿入される状態を示す縦断面図、図16は、図15に示したコネクタアッセンブリ210Aと相手側コネクタ50との嵌合途中状態を示す縦断面図である。なお、本第3実施形態に係るコネクタ210は、端子40に代えて端子40Bが用いられた以外は上記第1実施形態のコネクタ10と同様の構成であるので、同様の構成部材には同符号を付して詳細な説明を省略する。 Figure 15 is a vertical cross-sectional view showing the state in which the electric wire connection member 30 is inserted into the connector assembly 210A of the connector 210 according to the third embodiment of the present invention, and Figure 16 is a vertical cross-sectional view showing the connector assembly 210A shown in Figure 15 in the middle of mating with the mating connector 50. Note that the connector 210 according to this third embodiment has the same configuration as the connector 10 according to the first embodiment, except that the terminal 40B is used instead of the terminal 40. Therefore, the same components are designated by the same reference numerals and detailed description is omitted.

本第3実施形態に係るコネクタ210の端子40Bは、図15に示すように、端子接続部材20Bと電線接続部材30の2部品で構成されている。
端子接続部材20Bは、端子本体部22内に設けられた端子バネ25と、抜け止め片21Aと、スライド防止片29とを有する。そして、端子接続部材20Bがハウジング12の端子収容室18に収容されることで、コネクタ210のコネクタアッセンブリ210Aが構成される。
A terminal 40B of a connector 210 according to the third embodiment is composed of two parts, a terminal connecting member 20B and an electric wire connecting member 30, as shown in FIG.
The terminal connecting member 20B has a terminal spring 25 provided in the terminal main body 22, a retaining piece 21A, and a slide prevention piece 29. The terminal connecting member 20B is accommodated in the terminal accommodating chamber 18 of the housing 12, thereby forming a connector assembly 210A of the connector 210.

抜け止め片21Aは、端子本体部22を構成する側壁部である側壁22cに切り起こし形成されて先端が内方へ突出する矩形状の突出片である。抜け止め片21Aは、端子接続部材20Bの端子本体部22内に電線接続部材30の挿入片37が挿入された際、挿入片37の押圧突起39を端子バネ25の湾曲部28より後方位置で抜け止め係止する。 The retaining piece 21A is a rectangular protruding piece with a tip that protrudes inward and is cut into the side wall 22c that constitutes the terminal body 22. When the insertion piece 37 of the electric wire connection member 30 is inserted into the terminal body 22 of the terminal connection member 20B, the retaining piece 21A retains the pressing protrusion 39 of the insertion piece 37 at a position rearward of the curved portion 28 of the terminal spring 25.

スライド防止片29は、端子バネ25に対向する上壁22bに切り起こし形成されて先端が内方へ突出する矩形状の突出片であり、抜け止め片21Aよりも突出位置が端子本体部22の前方側とされる。スライド防止片29は、抜け止め片21Aにより抜け止め係止された電線接続部材30の挿入片37が挿入方向へ移動した際には、押圧突起39と係合して押圧突起39が端子バネ25の傾斜部26に抜け止め係止されるのを阻止する。また、スライド防止片29は、コネクタ210と相手側コネクタ50とが嵌合された際には、端子本体部22内に挿入された相手側端子70のタブ77によって押圧突起39と係合不可能な状態に弾性変形される。 The slide prevention piece 29 is a rectangular protruding piece that is cut and formed on the upper wall 22b facing the terminal spring 25 and has a tip that protrudes inward, and its protruding position is on the forward side of the terminal body 22 than the slip-out prevention piece 21A. When the insertion piece 37 of the electric wire connection member 30, which is locked by the slip-out prevention piece 21A, moves in the insertion direction, the slide prevention piece 29 engages with the pressing protrusion 39 to prevent the pressing protrusion 39 from being locked by the inclined portion 26 of the terminal spring 25. In addition, when the connector 210 and the mating connector 50 are mated, the slide prevention piece 29 is elastically deformed by the tab 77 of the mating terminal 70 inserted into the terminal body 22 into a state in which it cannot engage with the pressing protrusion 39.

そこで、図16に示すように、コネクタアッセンブリ210Aの端子収容室18に挿入された電線接続部材30は、端子接続部材20Bの抜け止め片21及びスライド防止片29によって、挿入片37の押圧突起39が端子接続部材20Bから抜け止め係止されると共に端子バネ25の傾斜部26に不用意に抜け止め係止されるのを阻止される。即ち、電線接続部材30は、端子接続部材20Bに対して不用意に結合することなく挿入方向に相対的なスライドが可能な仮保持状態で端子40Bを構成することができる。 As shown in FIG. 16, the wire connection member 30 inserted into the terminal receiving chamber 18 of the connector assembly 210A has the pressing protrusion 39 of the insertion piece 37 locked and prevented from slipping out of the terminal connection member 20B by the retaining piece 21 and the slide prevention piece 29 of the terminal connection member 20B, and is prevented from being inadvertently locked and prevented from slipping out of the terminal connection member 20B by the inclined portion 26 of the terminal spring 25. In other words, the wire connection member 30 can form the terminal 40B in a provisionally held state in which it can slide relatively in the insertion direction without being inadvertently coupled to the terminal connection member 20B.

即ち、電線接続部材30がコネクタアッセンブリ210Aの端子収容室18に挿入されて、仮保持状態として端子接続部材20Bに組み付けられることで、コネクタアッセンブリ210Aは端子40Bを端子収容室18に収容したコネクタ210となる。 That is, the electric wire connection member 30 is inserted into the terminal receiving chamber 18 of the connector assembly 210A and assembled to the terminal connection member 20B in a temporary holding state, so that the connector assembly 210A becomes a connector 210 with the terminal 40B received in the terminal receiving chamber 18.

次に、図15~図19を参照しながら上記コネクタ210と相手側コネクタ50とを嵌合する嵌合コネクタ201の組立手順を説明する。
図17は図16に示した電線接続部材30の挿入片37が端子接続部材20Bの抜け止め片21Aにより抜け止め係止され、挿入片37の押圧突起39が端子接続部材20Bの端子バネ25により抜け止め係止されるのを端子接続部材20Bのスライド防止片29により阻止された状態を示す要部拡大断面図、図18は図17に示した端子接続部材20Bのスライド防止片29が、相手側端子70のタブ77により挿入片37の押圧突起39と係合不可能な状態に弾性変形された状態を示す要部拡大断面図、図19は、図18に示した電線接続部材30の挿入片37が、端子接続部材20Bの端子バネ25により抜け止め係止された状態を示す要部拡大断面図である。
Next, a procedure for assembling the mating connector 201 for mating the connector 210 with the mating connector 50 will be described with reference to FIGS.
17 is an enlarged cross-sectional view of a main portion showing a state in which the insertion piece 37 of the wire connecting member 30 shown in FIG. 16 is locked in place by the anti-slip piece 21A of the terminal connecting member 20B, and the pressing protrusion 39 of the insertion piece 37 is prevented from being locked in place by the terminal spring 25 of the terminal connecting member 20B by the anti-slip piece 29 of the terminal connecting member 20B. FIG. 18 is an enlarged cross-sectional view of a main portion showing a state in which the anti-slip piece 29 of the terminal connecting member 20B shown in FIG. 17 is elastically deformed by the tab 77 of the mating terminal 70 into a state in which it cannot engage with the pressing protrusion 39 of the insertion piece 37. FIG. 19 is an enlarged cross-sectional view of a main portion showing a state in which the insertion piece 37 of the wire connecting member 30 shown in FIG. 18 is locked in place by the terminal spring 25 of the terminal connecting member 20B.

先ず、図15に示したように、電線60の端末に接続された電線接続部材30が、コネクタアッセンブリ210Aの端子収容室18にそれぞれ挿入される。そして、挿入片37の押圧突起39が端子接続部材20Bの抜け止め片21Aを押し広げながら通過し、押圧突起39はスライド防止片29と抜け止め片21Aとの間まで挿入される。 First, as shown in FIG. 15, the electric wire connection members 30 connected to the ends of the electric wires 60 are inserted into the terminal receiving chambers 18 of the connector assembly 210A. Then, the pressing protrusions 39 of the insertion pieces 37 pass through while pushing the retaining pieces 21A of the terminal connection member 20B apart, and the pressing protrusions 39 are inserted between the slide prevention pieces 29 and the retaining pieces 21A.

すると、端子接続部材20Bの抜け止め片21及びスライド防止片29によって挿入片37の押圧突起39が抜け止め係止されると共に端子バネ25の傾斜部26に不用意に抜け止め係止されるのを阻止された電線接続部材30は、端子接続部材20Bに対して不用意に結合することなく挿入方向に相対的なスライドが可能な仮保持状態となった端子40Bを構成する。即ち、コネクタアッセンブリ210Aの端子収容室18に収容された端子40Bは、電線接続部材30が端子接続部材20Bに対して仮保持状態とされたコネクタ210を構成する。この電線接続部材30が端子接続部材20Bに対して仮保持状態とされたコネクタ210は、運搬などにより取り扱う際、電線接続部材30と端子接続部材20Bとが不用意に分離してしまったり、不用意に結合してしまったりすることがない。 Then, the electric wire connection member 30, in which the pressing protrusion 39 of the insertion piece 37 is retained by the retaining piece 21 and the slide prevention piece 29 of the terminal connection member 20B and is prevented from being inadvertently retained by the inclined portion 26 of the terminal spring 25, constitutes a terminal 40B in a temporary retaining state in which the electric wire connection member 30 can slide relatively in the insertion direction without being inadvertently coupled to the terminal connection member 20B. That is, the terminal 40B accommodated in the terminal accommodation chamber 18 of the connector assembly 210A constitutes a connector 210 in which the electric wire connection member 30 is in a temporary retaining state relative to the terminal connection member 20B. The connector 210 in which the electric wire connection member 30 is in a temporary retaining state relative to the terminal connection member 20B does not accidentally separate or couple with the electric wire connection member 30 and the terminal connection member 20B when handled during transportation, etc.

次に、図16に示すように、相手側ハウジング52の嵌合空間58内にコネクタ210のハウジング12が嵌入される。この際、電線60の端末に接続された電線接続部材30は、挿入片37の押圧突起39が端子接続部材20Bの抜け止め片21及びスライド防止片29によって仮保持状態とされている。そこで、端子40Bの電線接続部材30は、コネクタ110から不用意に抜け落ちてしまったり、不用意に結合されてしまったりすることがなく、コネクタの嵌合作業性がよい。 Next, as shown in FIG. 16, the housing 12 of the connector 210 is fitted into the fitting space 58 of the mating housing 52. At this time, the wire connecting member 30 connected to the end of the wire 60 has the pressing protrusion 39 of the insertion piece 37 temporarily held by the retaining piece 21 and the slide prevention piece 29 of the terminal connecting member 20B. Therefore, the wire connecting member 30 of the terminal 40B does not accidentally fall out of the connector 110 or become inadvertently connected, and the connector fitting workability is good.

コネクタ210と相手側コネクタ50との嵌合過程では、図17に示すように、ハウジング12の端子挿入口13から端子収容室18に挿入された相手側端子70のタブ77が、端子本体部22内に挿入され、端子バネ25を弾性変形させる。 During the mating process between the connector 210 and the mating connector 50, as shown in FIG. 17, the tab 77 of the mating terminal 70 inserted into the terminal accommodating chamber 18 from the terminal insertion port 13 of the housing 12 is inserted into the terminal body 22, causing the terminal spring 25 to elastically deform.

そして、図18に示したように、コネクタ210と相手側コネクタ50との嵌合が完了すると、スライド防止片29は、端子本体部22内に挿入された相手側端子70のタブ77によって押圧突起39と係合不可能な状態に弾性変形される。また、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20Bの端子バネ25が接触する。 As shown in FIG. 18, when the mating of the connector 210 and the mating connector 50 is completed, the slide prevention piece 29 is elastically deformed by the tab 77 of the mating terminal 70 inserted into the terminal body 22 so that it cannot engage with the pressing protrusion 39. In addition, the restoring force caused by the elastic deformation of the terminal spring 25 brings the tab 77 of the mating terminal 70 into contact with the terminal spring 25 of the terminal connection member 20B.

次に、電線接続部材30の挿入片37が端子本体部22内にさらに挿入されることで、押圧突起39は端子バネ25の湾曲部28を押し上げながら通過する。そして、図19に示すように、端子接続部材20Bと電線接続部材30との結合が完了すると、押圧突起39は端子バネ25の傾斜部26に達する。このように、端子接続部材20Bと電線接続部材30とは、互いの結合が完了することで、一体的に連結されると共に電気的に接続されて本組み付け状態の端子40Bになる。 Next, the insertion piece 37 of the electric wire connection member 30 is further inserted into the terminal body 22, so that the pressing protrusion 39 passes through while pushing up the curved portion 28 of the terminal spring 25. Then, as shown in FIG. 19, when the connection between the terminal connection member 20B and the electric wire connection member 30 is completed, the pressing protrusion 39 reaches the inclined portion 26 of the terminal spring 25. In this way, when the connection between the terminal connection member 20B and the electric wire connection member 30 is completed, they are integrally linked and electrically connected to form the terminal 40B in the fully assembled state.

端子接続部材20Bと電線接続部材30との結合が完了して端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。そして、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とにより、相手側端子70のタブ77と端子接続部材20Bの端子バネ25とが接触する。
そこで、相手側端子70は、タブ77が端子接続部材20Bにおける端子バネ25と接触凸部27とに挟持される状態で、端子40Bに電気的に接続される。
When the connection between the terminal connection member 20B and the electric wire connection member 30 is completed, the pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25. Then, due to the restoring force due to the elastic deformation of the terminal spring 25 and the pressing force of the pressing protrusion 39 pressing the inclined portion 26 of the terminal spring 25, the tab 77 of the mating terminal 70 comes into contact with the terminal spring 25 of the terminal connection member 20B.
Thus, the mating terminal 70 is electrically connected to the terminal 40B with the tab 77 being clamped between the terminal spring 25 and the contact protrusion 27 of the terminal connecting member 20B.

次に、本第3実施形態に係るコネクタ210の作用効果を説明する。
上述したように、本第3実施形態に係るコネクタ210によれば、ハウジング12の端子収容室18に収容される端子40Bは、図15に示したように、端子接続部材20Bと電線接続部材30の2部品で構成されている。
Next, the effects of the connector 210 according to the third embodiment will be described.
As described above, according to the connector 210 of the third embodiment, the terminal 40B accommodated in the terminal accommodating chamber 18 of the housing 12 is composed of two parts, a terminal connecting member 20B and a wire connecting member 30, as shown in Figure 15.

そこで、先ずは3つの端子接続部材20Bをハウジング12の端子収容室18にそれぞれ挿入して可撓係止片15に抜け止め係止させることにより、コネクタ210のコネクタアッセンブリ210Aが組み立てられる。 First, the three terminal connection members 20B are inserted into the terminal accommodating chambers 18 of the housing 12 and locked into the flexible locking pieces 15 to prevent them from coming loose, thereby assembling the connector assembly 210A of the connector 210.

次に、電線60の端末に接続された電線接続部材30が、コネクタアッセンブリ210Aの端子収容室18にそれぞれ挿入される。この際、挿入片37の押圧突起39が、端子接続部材20Bにおけるスライド防止片29と抜け止め片21との間まで挿入される。 Next, the electric wire connection members 30 connected to the ends of the electric wires 60 are inserted into the terminal accommodating chambers 18 of the connector assembly 210A. At this time, the pressing protrusions 39 of the insertion pieces 37 are inserted between the slide prevention pieces 29 and the retaining pieces 21 of the terminal connection member 20B.

そして、電線接続部材30が端子接続部材20Bに対して不用意に結合することなく挿入方向に相対的なスライドが可能な仮保持状態となった端子40Bが構成される。即ち、端子40Bがコネクタアッセンブリ210Aの端子収容室18に収容されることにより、電線接続部材30が端子接続部材20Bに対して仮保持状態とされたコネクタ210が組み立てられる。 Then, the terminal 40B is formed in a provisionally held state in which the electric wire connection member 30 can slide relatively in the insertion direction without being inadvertently coupled to the terminal connection member 20B. That is, the terminal 40B is accommodated in the terminal accommodating chamber 18 of the connector assembly 210A, and the connector 210 is assembled in which the electric wire connection member 30 is provisionally held relative to the terminal connection member 20B.

そこで、端子40Bの電線接続部材30が端子接続部材20Bに対して仮保持状態とされたコネクタ210は、運搬などにより取り扱う際、電線接続部材30と端子接続部材20Bとが不用意に分離してしまったり、不用意に結合してしまったりするのを防止できる。 The connector 210, in which the electric wire connection member 30 of the terminal 40B is temporarily held relative to the terminal connection member 20B, can prevent the electric wire connection member 30 and the terminal connection member 20B from accidentally separating or joining together when handling the connector 210, such as during transportation.

次に、図16に示したように、コネクタ210が、相手側コネクタ50に嵌合される。この際、相手側端子70のタブ77が、端子接続部材20Bの端子本体部22内に挿入されて端子バネ25を弾性変形させる。そこで、端子バネ25の弾性変形による復元力により、相手側端子70のタブ77と端子接続部材20Bの端子バネ25が接触する。 Next, as shown in FIG. 16, the connector 210 is fitted into the mating connector 50. At this time, the tab 77 of the mating terminal 70 is inserted into the terminal body 22 of the terminal connection member 20B, elastically deforming the terminal spring 25. Then, due to the restoring force caused by the elastic deformation of the terminal spring 25, the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20B come into contact.

即ち、図17及び図18に示したように、端子接続部材20Bの端子本体部22内に挿入される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力だけが作用し、端子接続部材20Bの端子本体部22内に相手側端子70のタブ77を挿入する挿入力が高くなるのを抑えることができる。そのため、コネクタ210と相手側コネクタ50とを嵌合するコネクタ嵌合力も、高くなるのを抑えることができる。 That is, as shown in Figures 17 and 18, only the restoring force due to the elastic deformation of the terminal spring 25 acts on the tab 77 of the mating terminal 70 inserted into the terminal body 22 of the terminal connection member 20B, and the insertion force for inserting the tab 77 of the mating terminal 70 into the terminal body 22 of the terminal connection member 20B can be prevented from becoming too high. Therefore, the connector mating force for mating the connector 210 and the mating connector 50 can also be prevented from becoming too high.

さらに、コネクタ210が相手側コネクタ50に嵌合される際、電線60の端末に接続された電線接続部材30は、挿入片37の押圧突起39が端子接続部材20Bの抜け止め片21に抜け止め係止されると共に端子バネ25の傾斜部26に不用意に抜け止め係止されるのを阻止されている。そこで、端子40Bの電線接続部材30は、コネクタ嵌合作業中にコネクタ210から不用意に抜け落ちてしまうことがなく、コネクタの嵌合作業性がよい。 Furthermore, when the connector 210 is mated with the mating connector 50, the wire connection member 30 connected to the end of the wire 60 has the pressing protrusion 39 of the insertion piece 37 locked to the retaining piece 21 of the terminal connection member 20B and is prevented from being accidentally locked to the inclined portion 26 of the terminal spring 25. Therefore, the wire connection member 30 of the terminal 40B does not accidentally fall out of the connector 210 during the connector mating operation, and the connector mating operation is easy.

そして、電線接続部材30の挿入片37が端子本体部22内にさらに挿入されることで、押圧突起39は端子バネ25の湾曲部28を押し上げながら通過する。そして、図19に示すように、端子接続部材20Bと電線接続部材30との結合が完了すると、押圧突起39は端子バネ25の傾斜部26に達する。端子バネ25の傾斜部26に係合した挿入片37の押圧突起39は、端子バネ25の傾斜部26を押圧する。 Then, as the insertion piece 37 of the electric wire connection member 30 is further inserted into the terminal body 22, the pressing protrusion 39 passes through while pushing up the curved portion 28 of the terminal spring 25. Then, as shown in FIG. 19, when the connection between the terminal connection member 20B and the electric wire connection member 30 is completed, the pressing protrusion 39 reaches the inclined portion 26 of the terminal spring 25. The pressing protrusion 39 of the insertion piece 37 engaged with the inclined portion 26 of the terminal spring 25 presses the inclined portion 26 of the terminal spring 25.

即ち、端子接続部材20Bにおける端子バネ25と接触凸部27とに挟持される相手側端子70のタブ77に対しては、端子バネ25の弾性変形による復元力と、端子バネ25の傾斜部26を押圧する押圧突起39の押圧力とが作用し、相手側端子70のタブ77と端子接続部材20Bの端子バネ25とは強く接触することができる。 In other words, the tab 77 of the mating terminal 70, which is sandwiched between the terminal spring 25 and the contact protrusion 27 of the terminal connection member 20B, is subjected to the restoring force due to the elastic deformation of the terminal spring 25 and the pressing force of the pressing protrusion 39 pressing the inclined portion 26 of the terminal spring 25, so that the tab 77 of the mating terminal 70 and the terminal spring 25 of the terminal connection member 20B can come into strong contact.

そこで、3つの電線接続部材30がコネクタ210の端子接続部材20Bにそれぞれ接続されて組み立てられた嵌合コネクタ201は、端子40Bと相手側端子70とのガタ付きによる端子バネ25とタブ77との間での微摺動摩耗が抑制される。この微摺動摩耗の抑制により、微摺動摩耗により生じる摩耗粉が端子バネ25とタブ77との間に介在してしまうことが防止される。このため、端子40Bと相手側端子70の電気接続信頼性が低下することを抑制できる。
従って、本第3実施形態に係るコネクタ210によれば、コネクタ嵌合力が高くなるのを抑えつつ、端子40Bの微摺動摩耗を抑制することができる。
Therefore, in the mating connector 201 assembled by connecting the three electric wire connecting members 30 to the terminal connecting members 20B of the connector 210, micro-sliding wear between the terminal spring 25 and the tab 77 caused by rattle between the terminal 40B and the mating terminal 70 is suppressed. This suppression of micro-sliding wear prevents wear powder generated by micro-sliding wear from being interposed between the terminal spring 25 and the tab 77. This makes it possible to suppress a decrease in the reliability of the electrical connection between the terminal 40B and the mating terminal 70.
Therefore, according to the connector 210 of the third embodiment, it is possible to suppress the fricative wear of the terminals 40B while preventing the connector fitting force from becoming too high.

In addition, the material, shape, size, number, location, etc. of each component in the above-described embodiment are arbitrary as long as they can achieve the present invention, and are not limited.

例えば、上記実施形態では、相手側端子のタブとして雄端子である相手側端子70のタブ77を例に説明したが、これに限定されず相手側ハウジングに圧入されたバスバ端子とすることもできる。 For example, in the above embodiment, the tab of the mating terminal is described as being the tab 77 of the mating terminal 70, which is a male terminal, but this is not limited to this and the mating terminal may be a bus bar terminal that is press-fitted into the mating housing.
