Description

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

特許文献１に開示されるコネクタでは、ハウジングの内部空間に挿入される基板（接続部材）が、ハウジングに保持されたコンタクトの一対のビームの接触部間の隙間、或いは一方のビームの接触部と該接触部に対向するハウジングの内壁面との間の隙間を押し拡げながら、所定の挿入力で挿入される。ビームの弾性復元力で、基板とコンタクトとの接触圧力が確保される。特許文献１では、基板挿入の一動作により、基板の装着作業が達成される。 In the connector disclosed in Patent Document 1, the substrate (connecting member) inserted into the internal space of the housing is a gap between a pair of beam contact portions of contacts held in the housing, or a contact portion of one beam. It is inserted with a predetermined insertion force while expanding the gap between the inner wall surface of the housing facing the contact portion. The elastic restoring force of the beam ensures the contact pressure between the substrate and the contact. In Patent Document 1, a substrate mounting operation is achieved by one operation of inserting the substrate.

なお、括弧内の英数字は、後述する実施形態における対応構成要素等を表すが、このことは、むろん、本発明がそれらの実施形態に限定されるべきことを意味するものではない。以下、この項において同じ。
請求項２に記載の発明のように、前記挿入空間への挿入途中位置にある前記接続部材が前記第１状態の加圧部材によって加圧される状態で、前記挿入途中位置の前記接続部材の前記介在部と前記凸部とが当接することにより、前記導体部と前記接触部との間に隙間（Ｑ）が形成されてもよい。 The alphanumeric characters in parentheses represent the corresponding components and the like in the embodiments described later, but this does not mean that the present invention should be limited to those embodiments, of course. The same shall apply hereinafter in this section.
As in the invention according to claim 2, the connecting member at the insertion intermediate position is pressed by the pressurizing member in the first state, and the connecting member at the insertion intermediate position is pressed. A gap (Q) may be formed between the conductor portion and the contact portion by abutting the intervening portion and the convex portion.

請求項３に記載の発明のように、前記挿入方向に関して、前記接触部の少なくとも一部の位置が、前記凸部の少なくとも一部の位置と重なっていてもよい。
請求項４記載の発明のように、前記コンタクトが、前記接触部を前記接続部材側へ弾性的に付勢する付勢部（３２）を含み、前記加圧部材が前記第２状態に変位されて前記挿入完了位置にある前記接続部材に対する前記加圧部材の加圧が解除されることにより、前記コンタクトの前記付勢部の付勢力によって、前記接続部材が前記孔部を前記凸部から離脱させる側へ変位されることが許容されてもよい。 As in the invention of claim 3, at least a part of the contact portion may overlap the position of at least a part of the convex portion with respect to the insertion direction.
As in the invention of claim 4, the contact includes an urging portion (32) that elastically urges the contact portion toward the connecting member side, and the pressurizing member is displaced to the second state. When the pressurizing member is released from the pressure on the connecting member at the insertion completion position, the connecting member separates the hole from the convex portion by the urging force of the urging portion of the contact. It may be allowed to be displaced to the side to be displaced.

請求項５に記載の発明のように、前記加圧部材が、回動されることにより、前記コネクタ本体に設けられた開放部（２７）を開閉するカバーであり、前記カバーが、前記第１状態に相当する閉じ状態で前記接触部側およびその反対側に変位可能とされ、前記閉じ状態の前記カバーを前記接触部側へ弾性的に付勢する付勢要素（３３）をさらに備えていてもよい。 According to the fifth aspect of the present invention, the pressurizing member is rotated to open and close the opening portion (27) provided in the connector body, and the cover is the first cover. It is further provided with an urging element (33) that can be displaced to the contact portion side and the opposite side in the closed state corresponding to the state, and elastically urges the cover in the closed state to the contact portion side. May be good.

請求項１記載の発明では、加圧部材の第１状態で接続部材が前記挿入空間に挿入されるときに、挿入空間への接続部材の挿入途中位置で、凸部が接続部材の前記一方の面の介在部と当接することにより、接続部材が接触部から離隔する側に変位されて導体部と接触部との加圧接触が抑制される。また、挿入空間への接続部材の挿入完了位置で、凸部の少なくとも一部が孔部に挿入されることにより、加圧部材によって接続部材が接触部側に変位されて導体部と接触部とが加圧接触される。このため、接続部材の挿入の一動作で接続部材の装着作業が達成され且つ導体部の削れの発生が抑制される。 In the invention according to claim 1, when the connecting member is inserted into the insertion space in the first state of the pressurizing member, the convex portion is one of the connecting members at a position during insertion of the connecting member into the insertion space. By abutting with the intervening portion of the surface, the connecting member is displaced to the side separated from the contact portion, and the pressure contact between the conductor portion and the contact portion is suppressed. Further, at the position where the connection member is inserted into the insertion space, at least a part of the convex portion is inserted into the hole portion, so that the connection member is displaced toward the contact portion side by the pressure member, and the conductor portion and the contact portion Is pressurized and contacted. Therefore, the mounting work of the connecting member is achieved by one operation of inserting the connecting member, and the occurrence of scraping of the conductor portion is suppressed.

請求項２記載の発明では、挿入途中位置の接続部材の介在部と凸部とが当接することにより、導体部と接触部との間に隙間が形成される。このため、導体部の削れの発生が確実に抑制される。
請求項３記載の発明では、挿入方向に関して、接触部の少なくとも一部の位置が、凸部の少なくとも一部の位置と重なっている。これにより、接続部材の挿入途中位置において、凸部と接続部材の介在部との当接によって接触部と導体部との距離を拡大し易くなる。このため、導体部の削れの発生を抑制し易い。 In the invention according to claim 2, a gap is formed between the conductor portion and the contact portion by abutting the intervening portion and the convex portion of the connecting member at the position during insertion. Therefore, the occurrence of scraping of the conductor portion is surely suppressed.
In the invention according to claim 3, at least a part of the contact portion is overlapped with at least a part of the convex portion in the insertion direction. As a result, the distance between the contact portion and the conductor portion can be easily increased by the contact between the convex portion and the intervening portion of the connecting member at the position where the connecting member is being inserted. Therefore, it is easy to suppress the occurrence of scraping of the conductor portion.

請求項４記載の発明では、加圧部材が第２状態に変位されて、挿入完了位置にある接続部材に対する加圧部材の加圧が解除されることにより、コンタクトの付勢部の付勢力によって、接続部材が、孔部を凸部から離脱させる側へ変位されることが許容される。このため、接続部材をコネクタから容易に抜くことができる。
請求項５記載の発明では、接続部材が挿脱されるときに、閉じ状態のカバーが付勢要素によって弾性的に付勢された状態で接触部側とその反対側に変位される。このため、接続部材の挿脱をスムーズに行うことができる。 In the invention according to claim 4, the pressurizing member is displaced to the second state, and the pressurizing of the pressurizing member with respect to the connecting member at the insertion completion position is released, so that the urging force of the urging portion of the contact causes the pressure member. , It is permissible for the connecting member to be displaced to the side that separates the hole from the convex. Therefore, the connecting member can be easily pulled out from the connector.
In the invention according to claim 5, when the connecting member is inserted and removed, the closed cover is displaced to the contact portion side and the opposite side in a state of being elastically urged by the urging element. Therefore, the connecting member can be smoothly inserted and removed.

まず、図２（ａ）〜（ｆ）を参照して、接続部材６について説明する。接続部材６は、ＦＦＣ（フレキシブル・フラット・ケーブル）やＦＰＣ（フレキシブル・プリンテッド・サーキット）などのフレキシブルな平形の接続部材である。本実施形態では、接続部材６がＦＦＣである場合に則して説明する。 The connector 1 includes a connector main body 2, contacts 3A, 3B, 3C having different specifications, a cover 4 as a pressurizing member, and a pair of reinforcing tabs 5. The contacts 3A, 3B, and 3C having different specifications are arranged side by side in this order. In the following, when the contacts 3A to 3C having a plurality of specifications are generically referred to, they are simply referred to as the contact 3.
First, the connecting member 6 will be described with reference to FIGS. 2A to 2F. The connecting member 6 is a flexible flat connecting member such as an FFC (flexible flat cable) or an FPC (flexible printed circuit). In this embodiment, the case where the connecting member 6 is an FFC will be described.

接続部材６は、当該接続部材６の長手方向Ｌに延びる絶縁部６１と複数の導体部６２とを含む。絶縁部６１は、接続部材６の厚み方向Ｔに積層されたベース部６３とカバー部６４と補強板６５と含む。カバー部６４は、各導体部６２の端部６２ａが露出するように、ベース部６３および各導体部６２を覆っている。
補強板６５は、ベース部６３に対してカバー部６４とは反対側に配置されている。補強板６５は、ベース部６３に対して接続部材６の長手方向Ｌの一端６ｅから所定距離までの端部部分に積層され、該端部部分を補強している。 The connecting member 6 includes an insulating portion 61 extending in the longitudinal direction L of the connecting member 6 and a plurality of conductor portions 62. The insulating portion 61 includes a base portion 63, a cover portion 64, and a reinforcing plate 65 laminated in the thickness direction T of the connecting member 6. The cover portion 64 covers the base portion 63 and each conductor portion 62 so that the end portion 62a of each conductor portion 62 is exposed.
The reinforcing plate 65 is arranged on the side opposite to the cover portion 64 with respect to the base portion 63. The reinforcing plate 65 is laminated on the base portion 63 from one end 6e of the connecting member 6 in the longitudinal direction L to a predetermined distance to reinforce the end portion.

Specifically, the fixing portion 31 has a locking projection 31a that is locked to the connector main body 2 by press fitting. The first elastic piece portion 32 extends in a cantilever shape from the fixing portion 31 toward the extraction / removal direction X2, which is the opposite side of the insertion direction X1. The contact portion 32a is formed by one or a plurality of chevron portions arranged at the tip end portion of the first elastic piece portion 32 and projecting toward the second elastic piece portion 33 side.

第２弾性片部３３は、固定部３１から第１弾性片部３２と略平行に抜脱方向Ｘ２に向けて延設されている。第２弾性片部３３の先端部３３ａが、第１状態（閉じ状態）にあるカバー４を接続部材６側に押圧付勢する。
リード部３４ａは、基板の導体部分（図示せず）と接続される。接続片部３４は、固定部３１から基板側へ延びる第１部分３４ｂと、第１部分３４ｂの延設端部３４ｃから抜脱方向Ｘ２へ向けて延設された第２部分３４ｄと、第３部分３４ｅとを含む。第３部分３４ｅの延設端部によって、リード部３４ａが形成されている。 The second elastic piece portion 33 extends from the fixed portion 31 substantially parallel to the first elastic piece portion 32 in the extraction / removal direction X2. The tip 33a of the second elastic piece 33 presses and urges the cover 4 in the first state (closed state) toward the connecting member 6.
The lead portion 34a is connected to a conductor portion (not shown) of the substrate. The connecting piece portion 34 includes a first portion 34b extending from the fixing portion 31 toward the substrate side, a second portion 34d extending from the extending end portion 34c of the first portion 34b toward the extraction / removal direction X2, and a third portion 34d. Includes portion 34e. The lead portion 34a is formed by the extended end portion of the third portion 34e.

コンタクト３Ａの第２部分３４ｄの長さは、コンタクト３Ｂ，３Ｃの第２部分３４ｄの長さの略２倍とされている。コンタクト３Ａ，３Ｂでは、第３部分３４ｅが、第２部分３４ｄの延設端部３４ｆから基板側に向けて直交状に延設されている。コンタクト３Ｃでは、第３部分３４ｅが、第２部分３４ｄに対して直交配置された状態で第１部分３４ｂの延設端部３４ｃから基板側へ延設さている。 The length of the second portion 34d of the contact 3A is approximately twice the length of the second portion 34d of the contacts 3B and 3C.

On the other hand, referring to FIG. 2 (f), the difference between the total thickness t1 and the total thickness t2 corresponds to the thickness t3 of the conductor portion 62. That is, the following equation (6) holds.

From the equations (5) and (6), the following equation (7) is established.
E2-E1> t3 ... (7)
That is, the difference (E2-E1) between the second minimum gap E2 and the first minimum gap E1 is larger than the thickness t3 of the conductor portion 62. In other words, with respect to the protruding height from the inner surface 21d of the bottom wall portion, the difference obtained by subtracting the protruding height of the contact portion 32a from the protruding height of the top portion 72 of the convex portion 70 is made larger than the thickness t3 of the conductor portion 62. There is.

本実施形態によれば、カバー４（加圧部材）の閉じ状態で、接続部材６が一端６ｅ側から挿入方向Ｘ１にそってコネクタ本体２の挿入空間Ｓ１に挿入される。この挿入に際して、図７（ａ）に示すように、挿入空間Ｓ１への接続部材６の挿入途中位置で、コネクタ本体２の凸部７０が、接続部材６の一方の面６ａにおけるベース部６３の介在部６７と当接する。 According to the present embodiment, in the closed state of the cover 4 (pressurizing member), the connecting member 6 is inserted into the insertion space S1 of the connector main body 2 from one end 6e side along the insertion direction X1. At the time of this insertion, as shown in FIG. 7A, at the position where the connecting member 6 is being inserted into the insertion space S1, the convex portion 70 of the connector main body 2 is formed on the base portion 63 on one surface 6a of the connecting member 6. It comes into contact with the intervening portion 67.

このため、図７（ｂ）に示すように、挿入途中位置の接続部材６が、コンタクト３の接触部３２ａから離隔する側に変位されて、接続部材６の導体部６２と接触部３２ａとの間に、隙間Ｑ［図７（ｃ）を参照］が形成される。これにより、導体部６２と接触部３２ａとの加圧接触が回避される。すなわち、接続部材６の挿入時の導体部６２の削れの発生が抑制される。 Therefore, as shown in FIG. 7B, the connecting member 6 at the insertion intermediate position is displaced to the side separated from the contact portion 32a of the contact 3, and the conductor portion 62 of the connecting member 6 and the contact portion 32a are brought into contact with each other. A gap Q [see FIG. 7 (c)] is formed between them. As a result, pressure contact between the conductor portion 62 and the contact portion 32a is avoided. That is, the occurrence of scraping of the conductor portion 62 when the connecting member 6 is inserted is suppressed.

また、接続部材６の挿入に際して、図８（ａ）に示すように、挿入空間Ｓ１への接続部材６の挿入完了位置で、凸部７０の少なくとも一部が、接続部材６の孔部６６に挿入される。このため、図８（ｂ）に示すように、カバー４側からの加圧付勢によって接続部材６が接触部３２ａ側に変位されることが許容され、接続部材６の導体部６２と接触部３２ａとが加圧接触される。このように、接続部材６の挿入の一動作で接続部材６の装着作業（コネクタ１への接続作業）が達成され且つ導体部６２の削れの発生が抑制される。 Further, when the connecting member 6 is inserted, as shown in FIG. 8A, at least a part of the convex portion 70 is inserted into the hole portion 66 of the connecting member 6 at the insertion completion position of the connecting member 6 into the insertion space S1. Will be inserted. Therefore, as shown in FIG. 8B, the connecting member 6 is allowed to be displaced to the contact portion 32a side by the pressure urging from the cover 4 side, and the conductor portion 62 and the contact portion of the connecting member 6 are allowed to be displaced. Pressurized contact with 32a. In this way, the mounting work of the connecting member 6 (connecting work to the connector 1) is achieved by one operation of inserting the connecting member 6, and the occurrence of scraping of the conductor portion 62 is suppressed.

本実施形態では、カバー４が閉じ状態にあって、且つ、カバー４と凸部７０との間、およびカバー４とコンタクト３との間に、接続部材６が未挿入である状態で、カバー４（加圧部４１ｃ）とコネクタ本体２の凸部７０との最小隙間である第１最小隙間Ｅ１が、カバー４（加圧部４１ｃ）とコンタクト３の接触部３２ａとの最小隙間である第２最小隙間Ｅ２よりも小さくされている［Ｅ１＜Ｅ２。式（１）を参照］。また、第２最小隙間Ｅ２と第１最小隙間Ｅ１との差分Ｅ２−Ｅ１が、導体部６２の厚みｔ３よりも大きくされている［Ｅ２−Ｅ１＞ｔ３。式（７）を参照］。このため、図７（ｃ）に示すように、接続部材の挿入途中位置において、導体部６２と接触部３２ａとの間に隙間Ｑが形成されて、導体部６２と接触部３２ａとの間の加圧接触が抑制される。これにより、導体部６２の削れの発生が確実に防止される。 In the present embodiment, the cover 4 is in the closed state, and the connecting member 6 is not inserted between the cover 4 and the convex portion 70 and between the cover 4 and the contact 3. The first minimum gap E1, which is the minimum gap between the (pressurizing portion 41c) and the convex portion 70 of the connector body 2, is the second minimum gap between the cover 4 (pressurizing portion 41c) and the contact portion 32a of the contact 3. It is smaller than the minimum gap E2 [E1 <E2. See equation (1)]. Further, the difference E2-E1 between the second minimum gap E2 and the first minimum gap E1 is made larger than the thickness t3 of the conductor portion 62 [E2-E1> t3. See equation (7)]. Therefore, as shown in FIG. 7C, a gap Q is formed between the conductor portion 62 and the contact portion 32a at the position where the connecting member is being inserted, and the gap Q is formed between the conductor portion 62 and the contact portion 32a. Pressurized contact is suppressed. As a result, the occurrence of scraping of the conductor portion 62 is surely prevented.

ただし、第２最小隙間Ｅ２と第１最小隙間Ｅ１との差分（Ｅ２−Ｅ１）が、導体部６２の厚みと同等とされる場合（Ｅ２−Ｅ１≒ｔ３の場合）にも、接続部材６の挿入途中位置における導体部６２と接触部３２ａとの加圧接触を抑制して、導体部６２の削れの発生を抑制することができる。
また、図５（ａ）に示すように、挿入方向Ｘ１に関して、コネクタ本体２の凸部７０の少なくとも一部の位置と、コンタクト３の接触部３２ａの少なくとも一部の位置とが重なっている。このため、図７（ａ）に示すように、挿入途中位置の接続部材６の介在部６７とコネクタ本体２の凸部７０との当接によって、接触部３２ａと導体部６２との距離を拡大し易くなる。したがって、導体部６２の削れを抑制し易い。 However, even when the difference (E2-E1) between the second minimum gap E2 and the first minimum gap E1 is equal to the thickness of the conductor portion 62 (when E2-E1≈t3), the connecting member 6 It is possible to suppress the pressure contact between the conductor portion 62 and the contact portion 32a at the position during insertion, and to suppress the occurrence of scraping of the conductor portion 62.
Further, as shown in FIG. 5A, at least a part of the convex portion 70 of the connector main body 2 and at least a part of the contact portion 32a of the contact 3 overlap with each other in the insertion direction X1. Therefore, as shown in FIG. 7A, the distance between the contact portion 32a and the conductor portion 62 is increased by the contact between the intervening portion 67 of the connecting member 6 at the insertion intermediate position and the convex portion 70 of the connector main body 2. It becomes easier to do. Therefore, it is easy to suppress the scraping of the conductor portion 62.

また、コンタクト３が、接触部３２ａを接続部材６側へ弾性的に付勢する付勢部（第１弾性片部３２）を有している。このため、図９（ａ）に示すように、カバー４が開放状態に変位されて、挿入完了位置にある接続部材６に対するカバー４側からの加圧が解除されることにより、コンタクト３の第１弾性片部３２の付勢力によって、図９（ｂ）に示すように、接続部材６が孔部６６が凸部７０から離脱される側へ変位されることが許容される。このため、接続部材６をコネクタ本体２から抜脱方向Ｘ２へ容易に抜き出すことができる。 Further, the contact 3 has an urging portion (first elastic piece portion 32) that elastically urges the contact portion 32a toward the connecting member 6. Therefore, as shown in FIG. 9A, the cover 4 is displaced to the open state, and the pressurization from the cover 4 side to the connecting member 6 at the insertion completion position is released, so that the contact 3 becomes the third. 1 As shown in FIG. 9B, the urging force of the elastic piece portion 32 allows the connecting member 6 to be displaced to the side where the hole portion 66 is separated from the convex portion 70. Therefore, the connecting member 6 can be easily pulled out from the connector main body 2 in the pulling-out direction X2.

通例、カバー４の開放状態で、接続部材６が抜脱されるときは、基板１０から離れる側へ接続部材６が引っ張られる。このため、図９（ｂ）に示すように、凸部７０が若干量、孔部６６内に挿入された状態にあっても、接続部材６をコネクタ本体２から抜脱方向Ｘ２へ容易に抜き出すことができる。また、カバー４の開放状態における、接続部材６の抜脱時に、孔部６６の縁部６６ａが、凸部７０の断面凸湾曲状のコーナ部７４と当接することにより、接続部材６が抜脱され易くなっている。 Normally, when the connecting member 6 is pulled out while the cover 4 is open, the connecting member 6 is pulled toward the side away from the substrate 10. Therefore, as shown in FIG. 9B, the connecting member 6 can be easily pulled out from the connector main body 2 in the pulling-out direction X2 even when the convex portion 70 is inserted into the hole 66 by a small amount. be able to. Further, when the connecting member 6 is pulled out in the open state of the cover 4, the edge portion 66a of the hole portion 66 comes into contact with the corner portion 74 having a convex curved cross section of the convex portion 70, so that the connecting member 6 is pulled out. It is easy to be done.

また、加圧部材が開放部２７を開放させるカバー４で形成され、図７（ｂ）に示すように、カバー４が、閉じ状態で接触部３２ａ側およびその反対側に変位可能とされている。具体的には、図１（ａ）に示すように、カバー４の支軸４２ａが、回動支持部ＲＳによって、挿入方向Ｘ１および幅方向Ｗと直交する方向Ｙ（底壁部内面２１ｄと直交する方向に相当）に変位可能に支持されている。また、図７（ｂ）に示すように、閉じ状態のカバー４を接触部３２ａ側へ弾性的に付勢する第２弾性片部３３（付勢要素）が備えられている。このため、接続部材６が挿脱されるときに、閉じ状態のカバー４が、第２弾性片部３３によって弾性的に付勢された状態で、接触部３２ａ側とその反対側とに変位される。このため、接続部材６の挿脱をスムーズに行うことができる。 Further, the pressurizing member is formed by the cover 4 that opens the opening portion 27, and as shown in FIG. 7B, the cover 4 can be displaced to the contact portion 32a side and the opposite side in the closed state. .. Specifically, as shown in FIG. 1A, the support shaft 42a of the cover 4 is orthogonal to the insertion direction X1 and the width direction W by the rotation support portion RS (orthogonal to the bottom wall portion inner surface 21d). It is supported so that it can be displaced in (corresponding to the direction of movement). Further, as shown in FIG. 7B, a second elastic piece portion 33 (a urging element) for elastically urging the closed cover 4 toward the contact portion 32a is provided. Therefore, when the connecting member 6 is inserted and removed, the closed cover 4 is displaced to the contact portion 32a side and the opposite side in a state of being elastically urged by the second elastic piece portion 33. To. Therefore, the connecting member 6 can be smoothly inserted and removed.

また、凸部７０が、可動側であるカバー４ではなく、固定側であるコネクタ本体２に設けられているため、各凸部７０の位置精度が良い。このため、接続部材６の挿入時に、各凸部７０を接続部材６の対応する介在部６７に位置精度良く当接させることができる。したがって、接続部材６の挿入時に、凸部７０と導体部６２との干渉が防止されるので、凸部７０によって導体部６２が削られるおそれがない。 Further, since the convex portion 70 is provided not on the cover 4 on the movable side but on the connector main body 2 on the fixed side, the positional accuracy of each convex portion 70 is good. Therefore, when the connecting member 6 is inserted, each convex portion 70 can be brought into contact with the corresponding intervening portion 67 of the connecting member 6 with high positional accuracy. Therefore, when the connecting member 6 is inserted, the protrusion 70 and the conductor portion 62 are prevented from interfering with each other, so that the conductor portion 62 is not likely to be scraped by the convex portion 70.
