Description
本発明は、主にハイブリッド車や電気自動車等の高圧コネクタに用いられる端子構造に関する。 This invention relates primarily to a terminal structure used in high-voltage connectors for hybrid vehicles, electric vehicles, and the like.
高圧コネクタに用いられる端子構造の例として、特許文献１に記載のものが知られている。この端子構造は、筒状のメス端子と、メス端子の嵌合孔に嵌合される柱状のオス端子と、メス端子とオス端子の嵌合面間に介在される環状バネ導体と、を有するものである。この端子構造では、環状バネ導体としてリング状のコイルスプリングを使用し、メス端子とオス端子の嵌合面の一方に形成された環状溝に環状バネ導体を収容している。そして、両端子が嵌合された際に、環状溝に収容されたコイルスプリングが、自身の弾性反発力により両端子に押圧接触することで、両端子間を導通させるようになっている。 An example of a terminal structure used in high-voltage connectors is described in Patent Document 1. This terminal structure comprises a cylindrical female terminal, a columnar male terminal fitted into the mating hole of the female terminal, and an annular spring conductor interposed between the mating surfaces of the female and male terminals. In this terminal structure, a ring-shaped coil spring is used as the annular spring conductor, and the annular spring conductor is housed in an annular groove formed on one of the mating surfaces of the female and male terminals. When the two terminals are mated, the coil spring housed in the annular groove presses against both terminals due to its own elastic repulsive force, thereby creating electrical conductivity between the two terminals.
ところで、上述の従来の端子構造において、環状バネ導体として使用されているリング状のコイルスプリングは、直線状の形態で製作されたコイルスプリングを、円環状に湾曲させた上で、周方向の両端を突き合わせて精密に溶接や半田付けなどで接合することにより構成されている。したがって、この精密を要する接合作業に手間がかかる上に、製作工程で二酸化炭素を発生する等の改善すべき点があった。 Incidentally, in the conventional terminal structure described above, the ring-shaped coil spring used as the annular spring conductor is constructed by bending a linearly manufactured coil spring into an annular shape, and then precisely joining its circumferential ends together using welding or soldering. Therefore, this precise joining process is time-consuming, and there were areas for improvement, such as the generation of carbon dioxide during the manufacturing process.
また、リング状のコイルスプリングを環状溝に配置する際には、コイルスプリングのリング内径が広がるようコイルリングを変形させながら組付ける必要があり、この組付けによって接合部分に破損や変形を生じたりして、組付け不良が発生する可能性があった。組付け不良が発生すると、端子接続の際の導通不良に繋がるおそれがある。 Furthermore, when arranging a ring-shaped coil spring in an annular groove, it is necessary to deform the coil ring to expand its inner diameter during assembly. This assembly process could potentially cause damage or deformation at the joint, leading to assembly defects. Such assembly defects could result in poor electrical conductivity during terminal connection.
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、環状バネ導体を製作する際の溶接や半田付け等の接合作業を無くすことができると共に、簡単に、環状の形態を保ちながら、環状バネ導体をオス端子またはメス端子に不良を生じることなく組付けることのできて、電気接続の信頼性向上が図れる端子構造を提供することにある。 This invention has been made in view of the circumstances described above, and its purpose is to provide a terminal structure that eliminates welding, soldering, and other joining work when manufacturing annular spring conductors, and that allows for easy assembly of annular spring conductors to male or female terminals without causing defects while maintaining an annular shape, thereby improving the reliability of electrical connections.
前述した目的を達成するために、本発明に係る端子構造は、下記を特徴としている。 To achieve the aforementioned objectives, the terminal structure according to the present invention is characterized by the following:

A cylindrical female terminal with a fitting hole formed along the axial direction,
A columnar male terminal that fits into the fitting hole of the female terminal,
An annular spring conductor is interposed in a compressed state between the mating surfaces of the female terminal and the male terminal, and by pressing into contact with the mating surfaces of the female terminal and the male terminal, it causes the female terminal and the male terminal to be electrically connected to each other.
A retaining ring is retrofitted and fixed to either the inner circumference of the fitting hole of the female terminal or the outer circumference of the male terminal,

The aforementioned annular spring conductor is formed by curving a spring member, which has the ability to return to a straight shape, into an annular shape.
A terminal structure in which the retaining ring is provided with a locking portion, and the circumferential end of the spring member is locked to the locking portion.
本発明によれば、環状バネ導体を構成するために環状に湾曲させたバネ部材の周方向の端部を、保持リングに形成した係止部に係止させることにより、環状バネ導体を安定した形態で端子に簡単に組付けることができる。したがって、溶接や半田付けなどでバネ部材の端部同士を接合する必要がなく、接合作業にかかる手間を減らせると共に、二酸化炭素の発生に関しての改善効果を得ることができる。また、接合部分を持たないので、接合部分が破損したり変形したりして組付け不良を生じる心配がなく、電気接続の信頼性向上が図れる。 According to this invention, by engaging the circumferential ends of a spring member, which is curved in an annular shape to form an annular spring conductor, with locking parts formed on a retaining ring, the annular spring conductor can be easily assembled to a terminal in a stable form. Therefore, there is no need to join the ends of the spring members by welding or soldering, reducing the effort required for joining work and providing an improvement in carbon dioxide emissions. Furthermore, because there are no joint parts, there is no concern about assembly defects due to damage or deformation of the joint parts, thus improving the reliability of electrical connections.
以上、本発明について簡潔に説明した。更に、以下に説明される発明を実施するための形態（以下、「実施形態」という。）を添付の図面を参照して通読することにより、本発明の詳細は更に明確化されるであろう。 The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by referring to the accompanying drawings and reading through the embodiments for carrying out the invention described below (hereinafter referred to as "embodiments").
本発明に関する具体的な実施形態について、各図を参照しながら以下に説明する。 Specific embodiments of the present invention will be described below with reference to the figures.
図１は、本発明の一実施形態に係る端子構造を含むコネクタ装置の分解斜視図である。 Figure 1 is an exploded perspective view of a connector device including a terminal structure according to one embodiment of the present invention.
本実施形態の端子構造は、図１に示すコネクタ装置１に組み込まれている。このコネクタ装置１は、主に高圧コネクタに使用されるもので、メス側コネクタの主要部としてハウジングＨに組み込まれたメス端子１０と、オス側コネクタ２とを備えている。オス側コネクタ２は、オス端子２０を有している。 The terminal structure of this embodiment is incorporated into the connector device 1 shown in Figure 1. This connector device 1 is primarily used for high-voltage connectors and comprises a female terminal 10 incorporated into a housing H as the main part of the female connector, and a male connector 2. The male connector 2 has a male terminal 20.
メス端子１０は、有底円筒状のもので、図１には示されていないが、軸線方向Ｘ（コネクタ嵌合方向）に沿って形成された円形断面の嵌合孔を有している。オス端子２０は、軸線方向Ｘに沿って移動することでメス端子１０の嵌合孔に嵌合される円柱ロッド形状の部品である。このオス端子２０には、メス端子１０とオス端子２０の嵌合面の間に介在される環状バネ導体３０と、環状バネ導体３０を保持する保持リング４０と、が装着されている。メス端子１０およびオス端子２０は、例えば、銅または銅合金等の導電性金属材料により形成されている。 The female terminal 10 is a bottomed cylindrical shape and, although not shown in Figure 1, has a circular cross-section mating hole formed along the axial direction X (connector mating direction). The male terminal 20 is a cylindrical rod-shaped component that moves along the axial direction X to fit into the mating hole of the female terminal 10. The male terminal 20 is fitted with an annular spring conductor 30 interposed between the mating surfaces of the female terminal 10 and the male terminal 20, and a retaining ring 40 that holds the annular spring conductor 30. The female terminal 10 and the male terminal 20 are made of a conductive metal material such as copper or a copper alloy.
環状バネ導体３０は、メス端子１０とオス端子２０の嵌合面の間に圧縮状態で介在され、メス端子１０とオス端子２０の嵌合面に押圧接触することで、メス端子１０とオス端子２０を相互に導通させるものである。 The annular spring conductor 30 is interposed in a compressed state between the mating surfaces of the female terminal 10 and the male terminal 20, and by pressing into contact with the mating surfaces of the female terminal 10 and the male terminal 20, it causes electrical conductivity between the two terminals.
図２は、本実施形態のコネクタ装置におけるオス側コネクタの構成を示す分解斜視図、図３は、オス側コネクタの組立状態の構成を示す斜視図、図４は、図３のＡ矢視要部拡大図である。 Figure 2 is an exploded perspective view showing the configuration of the male connector in the connector device of this embodiment, Figure 3 is a perspective view showing the configuration of the assembled male connector, and Figure 4 is an enlarged view of the main part as seen through arrow A in Figure 3.
図２～図４に示すように、ここで使用されている環状バネ導体３０は、導電性及び弾性を有する金属線条体を螺旋状に巻回したコイルスプリングを円環状に湾曲させて丸めたものである。コイルスプリングは、直線状の形態への復元性を有するバネ部材である。このコイルスプリングからなるバネ部材３０Ａは、円環状に湾曲された状態でも、周方向の両端部３１、３１が、溶接や半田付けなどで互いに接合されておらず、自由端として開放されている。但し、保持リング４０の係止部に係止させやすくするため、端末形状処理（例えばフック形状にするなど）が施されていてもよい。 As shown in Figures 2 to 4, the annular spring conductor 30 used here is formed by winding a conductive and elastic metal wire spirally into a coil spring, which is then curved and rounded into an annular shape. The coil spring is a spring member that has the ability to return to a straight shape. Even when the spring member 30A, consisting of this coil spring, is curved into an annular shape, both circumferential ends 31, 31 are not joined to each other by welding or soldering, and are left open as free ends. However, to facilitate locking into the locking portion of the retaining ring 40, the ends may be shaped (for example, into a hook shape).
オス端子２０の外周に後付けで装着された保持リング４０は、オス端子２０をメス端子１０の嵌合孔に嵌合した際に嵌合孔の入口を塞ぐキャップの機能を併せ持つものであり、金属や樹脂などで構成されている。この保持リング４０は、オス端子２０の基端部の外周に、軸線方向Ｘおよび周方向に動かないように嵌合固定されている。この保持リング４０のオス端子２０の先端側の端面４０ａの周方向の１箇所には、係止突片５０が突設されている。この係止突片５０の周方向の両側部には、対称形状の係止フック（係止部）５１が形成されている。周方向の両側部の係止フック５１は、それぞれ前方から後方に向けて延びるカギ形をなしている。 The retaining ring 40, which is retrofitted to the outer circumference of the male terminal 20, also functions as a cap that closes the entrance to the fitting hole when the male terminal 20 is fitted into the fitting hole of the female terminal 10. It is made of metal or resin. This retaining ring 40 is fitted and fixed to the outer circumference of the base end of the male terminal 20, preventing movement in the axial X direction and the circumferential direction. A locking projection 50 is provided at one point in the circumferential direction on the end face 40a of the retaining ring 40 on the tip side of the male terminal 20. Symmetrical locking hooks (locking parts) 51 are formed on both sides of this locking projection 50 in the circumferential direction. The locking hooks 51 on both sides in the circumferential direction are hook-shaped, extending from front to rear.
環状バネ導体３０を構成するために円環状に湾曲させたコイルスプリング（バネ部材３０Ａ）の周方向の両端部３１、３１は、保持リング４０の係止突片５０の周方向の両側部に設けた係止フック５１にそれぞれ係止されている。 The circumferential ends 31, 31 of the coil spring (spring member 30A), which is curved in an annular shape to form the annular spring conductor 30, are respectively locked to locking hooks 51 provided on both sides in the circumferential direction of the locking projection 50 of the retaining ring 40.
図５は、オス側コネクタ２の作用説明図である。
図４および図５に示すように、係止フック５１は、コイルスプリング（バネ部材３０Ａ）の軸線方向の動き（図５中矢印Ｆ２で示す動き）を規制するための前端バー５１ａ（移動規制部）を有している。また、係止フック５１は、コイルスプリング（バネ部材３０Ａ）が直線状の形態に戻ろうとする復元力（図５中矢印Ｆ１で示す力）を規制するための側端バー５１ｂ（復元力規制部）を有している。前端バー５１ａは、係止突片５０の先端から周方向外方に延びており、側端バー５１ｂは、前端バー５１ａの先端から直角に曲がって後方に延びている。
Figure 5 is an explanatory diagram of the operation of the male connector 2.
As shown in Figures 4 and 5, the locking hook 51 has a front end bar 51a (movement restricting part) for restricting the axial movement of the coil spring (spring member 30A) (movement indicated by arrow F2 in Figure 5). The locking hook 51 also has a side end bar 51b (restoring force restricting part) for restricting the restoring force (force indicated by arrow F1 in Figure 5) that causes the coil spring (spring member 30A) to return to a straight shape. The front end bar 51a extends circumferentially outward from the tip of the locking projection 50, and the side end bar 51b bends at a right angle from the tip of the front end bar 51a and extends rearward.
また、側端バー５１ｂの後端からは後端バー５１ｃが、前端バー５１ａと平行に周方向内方に直角に曲がって短く延びている。更に、後端バー５１ｃとの係止突片５０の基端部との間には、コイルスプリング（バネ部材３０Ａ）の周方向の端部３１を、前端バー５１ａと側端バー５１ｂと後端バー５１ｃとで囲まれた係止空所５１ｄに挿入することのできる隙間５１ｅが確保されている。 Furthermore, the rear end bar 51c extends from the rear end of the side end bar 51b, bending perpendicularly inward in the circumferential direction and parallel to the front end bar 51a. Additionally, a gap 51e is provided between the base end of the locking projection 50 and the rear end bar 51c, allowing the circumferential end 31 of the coil spring (spring member 30A) to be inserted into the locking cavity 51d enclosed by the front end bar 51a, the side end bar 51b, and the rear end bar 51c.
なお、図３に示すように、係止フック５１とオス端子２０の外周との間には、環状バネ導体３０の組付けが容易な程度に隙間が確保されている。また、図５に示すように、組付け状態の環状バネ導体３０の最外径は、保持リング４０の最外径よりも大きくなるように設定されている。 As shown in Figure 3, a gap is provided between the locking hook 51 and the outer circumference of the male terminal 20 to facilitate the assembly of the annular spring conductor 30. Furthermore, as shown in Figure 5, the outermost diameter of the assembled annular spring conductor 30 is set to be larger than the outermost diameter of the retaining ring 40.
また、保持リング４０を、肉厚円筒状のリング本体と、板金等で製作した板体リングとに分けて製作し、係止突片５０を有した板体リングをリング本体の外周に嵌合固定することで、保持リング４０を構成するようにすることもできる。 Furthermore, the retaining ring 40 can also be constructed by dividing it into a thick cylindrical ring body and a plate ring made of sheet metal or the like. The plate ring, which has a locking projection 50, can then be fitted and fixed to the outer circumference of the ring body to form the retaining ring 40.
次に、コネクタ装置１の組み立てについて説明する。
まず、オス端子２０に保持リング４０（キャップ）を組付ける。次に保持リング４０の組付け後に、環状バネ導体３０をオス端子２０の外周に組付ける。即ち、環状バネ導体３０を構成するコイルスプリング（バネ部材３０Ａ）を、オス端子２０の外周に湾曲させながら巻き付ける。そして、巻き付けながら、コイルスプリング（バネ部材３０Ａ）の周方向の両端部３１、３１を、係止突片５０の２つの係止フック５１にそれぞれ引っ掛けて係止させる。
Next, we will explain how to assemble the connector device 1.
First, the retaining ring 40 (cap) is attached to the male terminal 20. Next, after attaching the retaining ring 40, the annular spring conductor 30 is attached to the outer circumference of the male terminal 20. That is, the coil spring (spring member 30A) that makes up the annular spring conductor 30 is wound around the outer circumference of the male terminal 20 in a curved manner. While winding, the circumferential ends 31, 31 of the coil spring (spring member 30A) are hooked onto the two locking hooks 51 of the locking projection 50 and locked in place.
これにより、コイルスプリング３０Ａで構成された環状バネ導体３０が、一定の円環状の形態を保ちながらオス端子２０に装着されて、オス側コネクタ２が完成する。この状態で、環状バネ導体３０は、側端バー５１ｂによって直線状の形態に復元しないよう規制され、また、前端バー５１ａによって軸方向に位置ずれしないように規制されている。よって、このオス側コネクタ２をメスコネクタのメス端子１０に嵌合することによって、コネクタ装置の電気接続を成立させることができる。 As a result, the annular spring conductor 30, composed of coil springs 30A, is attached to the male terminal 20 while maintaining a constant annular shape, completing the male connector 2. In this state, the annular spring conductor 30 is restricted by the side end bar 51b to prevent it from returning to a straight shape, and is also restricted by the front end bar 51a to prevent axial displacement. Therefore, by mating this male connector 2 with the female terminal 10 of the female connector, the electrical connection of the connector device can be established.
以上説明したように、本実施形態の端子構造によれば、環状バネ導体３０を構成するために円環状に湾曲させたバネ部材３０Ａ（コイルスプリング）の周方向の端部３１を、保持リング４０に形成した係止フック５１に係止させるだけで、環状バネ導体３０を安定した形態でオス端子２０に簡単に組付けることができる。 As described above, according to the terminal structure of this embodiment, the annular spring conductor 30 can be easily assembled to the male terminal 20 in a stable manner simply by engaging the circumferential end 31 of the spring member 30A (coil spring), which is curved in an annular shape to form the annular spring conductor 30, with the locking hook 51 formed on the retaining ring 40.
したがって、溶接や半田付けなどでバネ部材３０Ａの端部同士を接合する必要がなく、接合作業にかかる手間を減らせると共に、二酸化炭素の発生に関しての改善効果を得ることができる。また、接合部分を持たないので、接合部分が破損したり変形したりして組付け不良を生じる心配がなく、電気接続の信頼性向上が図れる。 Therefore, there is no need to join the ends of the spring members 30A by welding or soldering, reducing the effort required for joining and providing an improvement in carbon dioxide emissions. Furthermore, because there are no joints, there is no concern about assembly defects due to damage or deformation of the joints, thus improving the reliability of electrical connections.
また、本端子構造によれば、コネクタ装置の嵌合時に、コイルスプリングよりなる環状バネ導体３０を潰すように圧縮させることができるので、接触面積の増大により、電気接続の信頼性および性能をより高めることができる。 Furthermore, this terminal structure allows the annular spring conductor 30, which is made of a coil spring, to be compressed during the mating of the connector device. This increases the contact area, thereby improving the reliability and performance of the electrical connection.
なお、本発明は、上述した実施形態に限定されるものではなく、適宜、変形、改良、等が可能である。その他、上述した実施形態における各構成要素の材質、形状、寸法、数、配置箇所、等は本発明を達成できるものであれば任意であり、限定されない。 Furthermore, the present invention is not limited to the embodiments described above, and modifications, improvements, etc., are possible as appropriate. In addition, the material, shape, dimensions, number, placement, etc., of each component in the embodiments described above are arbitrary and not limited, as long as they achieve the present invention.
例えば、上記実施形態では、コイルスプリングよりなる環状バネ導体３０の両端部３１、３１を係止する係止部として、カギ形の係止フック５１を形成した場合を示したが、係止フック５１の代わりに、係止突片５０に２つの係止孔を形成し、それぞれの係止孔に、環状バネ導体３０の両端部３１、３１を挿入係止させるようにしてもよい。この場合、環状バネ導体３０を回転させるようにしながら両端部３１、３１を係止孔に挿入する必要が生じるものの、係止フック５１の場合と比較して、環状バネ導体３０が外れにくくなる。逆に、係止フック５１を用いた場合には、環状バネ導体３０を回転させることなく両端部３１、３１を係止フック５１に係止することができるので、作業性が向上する。 For example, in the above embodiment, a key-shaped locking hook 51 was shown as a locking part for securing both ends 31, 31 of the annular spring conductor 30 made of a coil spring. However, instead of the locking hook 51, two locking holes may be formed in the locking projection 50, and both ends 31, 31 of the annular spring conductor 30 may be inserted and locked into each locking hole. In this case, it becomes necessary to insert both ends 31, 31 into the locking holes while rotating the annular spring conductor 30, but the annular spring conductor 30 is less likely to come loose compared to the case with the locking hook 51. Conversely, when using the locking hook 51, both ends 31, 31 can be locked to the locking hook 51 without rotating the annular spring conductor 30, thus improving work efficiency.
また、係止突片５０を２本突設し、各係止突片５０を係止部として、それら係止部に環状バネ導体３０の両端部３１、３１を引っ掛けて係止してもよい。 Alternatively, two locking projections 50 may be provided, and each locking projection 50 may be used as a locking part. The ends 31, 31 of the annular spring conductor 30 may then be hooked onto these locking parts to secure it.
また、円環状の環状バネ導体３０を、周方向に複数（例えば、半周ずつの２つ）に分割して構成してもよい。即ち、複数のコイルスプリングを直列に配列し、これら複数のコイルスプリングを湾曲させた際の周方向の各端部を、保持リング４０に周方向に離間して配した複数の係止部（例えば、係止フック５１）にそれぞれ係止させてもよい。 Furthermore, the annular spring conductor 30 may be divided into multiple sections in the circumferential direction (for example, two sections each representing half a turn). That is, multiple coil springs may be arranged in series, and the circumferential ends of these curved coil springs may be locked to multiple locking parts (for example, locking hooks 51) arranged circumferentially spaced apart on the retaining ring 40.
また、環状バネ導体３０を構成するバネ部材３０Ａとしては、コイルスプリングの使用が最適であるが、それ以外のバネ部材を使用してもよい。 Furthermore, while a coil spring is optimal as the spring member 30A constituting the annular spring conductor 30, other spring members may also be used.
また、上記実施形態では、保持リング４０や環状バネ導体３０を、オス端子２０に装着する場合を示したが、メス端子の嵌合孔の内周側に後付けで装着してもよい。 Furthermore, although the above embodiment shows the retaining ring 40 and the annular spring conductor 30 being attached to the male terminal 20, they may also be attached to the inner circumference of the mating hole of the female terminal afterwards.
ここで、上述した本発明の実施形態に係る端子構造の特徴をそれぞれ以下［１］～［５］に簡潔に纏めて列記する。

Terminal structure.
上記［１］の構成によれば、環状バネ導体（３０）を構成するために円環状に湾曲させたバネ部材（３０Ａ）の周方向の端部（３１）を、保持リング（４０）に形成した係止部（５１）に係止させるだけで、環状バネ導体（３０）を安定した形態でオス端子（２０）に簡単に組付けることができる。したがって、溶接や半田付けなどでバネ部材（３０Ａ）の端部（３１）同士を接合する必要がなく、接合作業にかかる手間を減らせると共に、二酸化炭素の発生に関しての改善効果を得ることができる。また、接合部分を持たないので、接合部分が破損したり変形したりして組付け不良を生じる心配がなく、電気接続の信頼性向上が図れる。 According to the configuration described in [1] above, the annular spring conductor (30) can be easily assembled to the male terminal (20) in a stable form simply by locking the circumferential end (31) of the spring member (30A), which is curved in an annular shape to form the annular spring conductor (30), to the locking portion (51) formed on the retaining ring (40). Therefore, there is no need to join the ends (31) of the spring member (30A) by welding or soldering, which reduces the effort required for joining work and provides an improvement in carbon dioxide emissions.
