Description

【０００１】
【発明の属する技術分野】
この発明は、プラグコネクタハウジング及びレセプタクルコネクタハウジング同士を相互に容易に嵌合させたり、離脱させたりすることができるスライダ付きコネクタに関する。
【０００２】
【従来の技術】
現在、エレクトロニクス化の急速な発展により、例えば自動車に搭載されるワイヤハーネスなどにおいても回路数（電線数）が年々増加する傾向にある。回路数の増加に伴い、ワイヤハーネスの端末部に取り付けられるコネクタも多極化（内蔵接続端子数の増加）が進展し、図１２に示すような多極コネクタが多く使用されるようになってきた。この多極コネクタ１００は、内部に複数のレセプタクル接続端子（図示せず）を収容するための端子収容孔１０１が形成されたプラグコネクタハウジング１１０と、このプラグコネクタハウジング１１０が内側に嵌合すると共に内部に複数のプラグ接続端子１０２を収容するための端子収容孔（図示せず）が形成されたレセプタクルコネクタハウジング１２０と、このレセプタクルコネクタハウジング１２０に別途取り付けられたレバー１３０とから構成されている。この多極コネクタ１００のように、接続する接続端子数が増えれば、プラグコネクタハウジング１１０及びレセプタクルコネクタハウジング１２０同士の嵌合時／離脱時の接触抵抗が増加するため、両者の嵌合時の挿入力及び離脱時の引抜力もより高くなってしまう。そこで、これらの挿入力及び引抜力を低く抑えるために、レバー１３０等の倍力機構を備え、例えばプラグコネクタハウジング１１０の側面に突起１１１を形成し、レバー１３０にこの突起１１１と嵌合すると共にこの突起１１１をレセプタクルコネクタハウジング１２０の奥側に移動させるための溝１２１を形成して、レバー１３０を動かすことによりてこの原理を利用して両者を嵌合／離脱するようにしたレバー式コネクタが知られている。また、レバー１３０の代わりに、スライダ（図示せず）等の補助機構を備え、両者を嵌合／離脱するようにしたいわゆるスライダ付き低挿入力コネクタが知られている（例えば、特許文献１及び２参照。）。

【発明が解決しようとする課題】
しかしながら、スライダ付き低挿入力コネクタに用いられているスライダのような補助機構の場合、より大きな力をスライダから出させるためには、スライダの長さを必要量長くとらなくてはならないため、スライダ自体が大きくなってしまうと共にスライダを動かすスペースが必要となり全体的にコネクタが大きくなってしまう。
【０００５】
この発明は、このような事情に鑑みてなされたもので、スライダの大型化を図らずにスライダによる挿入力を大きくすることができると共に全体的な大きさを抑えることができるスライダ付き低挿入力コネクタを提供することを目的とする。
【０００６】
【課題を解決するための手段】
この発明に係る第１のスライダ付き低挿入力コネクタは、プラグコネクタハウジングと、このプラグコネクタハウジングと嵌合するレセプタクルコネクタハウジングと、このレセプタクルコネクタハウジングにスライド自在に装着されたスライダとを有するスライダ付き低挿入力コネクタであって、前記プラグコネクタハウジングは、側壁を有しこの側壁に沿って前記レセプタクルコネクタハウジングと嵌合する嵌合本体部と、この嵌合本体部の側壁の外面に設けられたガイド用突起とを備え、前記レセプタクルコネクタハウジングは、壁部を有しこの壁部に沿って前記プラグコネクタハウジングの嵌合本体部が内側に嵌合し、嵌合時に前記ガイド用突起が移動可能となるように前記壁部にスリット部が形成された縦断面が凹状の嵌合部を備え、前記スライダは、前記嵌合部の壁部の外面側に開閉自在に設けられた第１及び第２のスライダを備え、前記第１及び第２のスライダは、それらのスライド方向に延びる、一部が互いに重なるアームプレートを有し、前記第１のスライダのアームプレートには、前記プラグコネクタハウジングのガイド用突起と嵌合し、前記第１のスライダを開状態から閉状態へとスライドさせる過程で前記ガイド用突起を介して前記プラグコネクタハウジングを前記レセプタクルコネクタハウジングに対して嵌合途中位置まで移動させる第１ガイド孔、及びこの第１ガイド孔と連通し両コネクタハウジングが完全嵌合される方向に前記ガイド用突起を介して前記プラグコネクタハウジングを移動可能とさせる副ガイド孔が形成され、前記第２のスライダのアームプレートには、前記プラグコネクタハウジングのガイド用突起と嵌合し、前記第２のスライダを開状態から閉状態へとスライドさせる過程で前記ガイド用突起を介して前記プラグコネクタハウジングを前記レセプタクルコネクタハウジングに対して嵌合途中位置から完全嵌合位置まで移動させる第２ガイド孔が形成されていることを特徴とする。
【０００７】
この発明に係る第２のスライダ付き低挿入力コネクタは、プラグコネクタハウジングと、このプラグコネクタハウジングと嵌合するレセプタクルコネクタハウジングと、このレセプタクルコネクタハウジングに両コネクタハウジングの嵌合方向と直交する方向にスライド自在に装着されたスライダとを有するスライダ付き低挿入力コネクタであって、前記プラグコネクタハウジングは、側壁を有しこの側壁に沿って前記レセプタクルコネクタハウジングと嵌合する嵌合本体部と、この嵌合本体部の側壁の外面に設けられたガイド用突起とを備え、前記レセプタクルコネクタハウジングは、壁部を有しこの壁部に沿って前記プラグコネクタハウジングの嵌合本体部が内側に嵌合し、嵌合時に前記ガイド用突起が移動可能となるように前記壁部にスリット部が形成された縦断面が凹状の嵌合部を備え、前記スライダは、前記嵌合部の壁部の外面を前記嵌合方向と直交する方向に開閉自在に設けられた第１及び第２のスライダを備え、前記第１及び第２のスライダは、それらのスライド方向に延びる、一部が互いに重なるアームプレートを有し、前記第１のスライダのアームプレートには、前記プラグコネクタハウジングのガイド用突起と嵌合し、前記第１のスライダを開状態から閉状態へとスライドさせる過程で前記ガイド用突起を介して前記プラグコネクタハウジングを前記レセプタクルコネクタハウジングに対して嵌合途中位置まで移動させる第１ガイド孔、及びこの第１ガイド孔と連通し両コネクタハウジングが完全嵌合される方向に前記ガイド用突起を介して前記プラグコネクタハウジングを移動可能とさせる副ガイド孔が形成され、前記第２のスライダのアームプレートには、前記プラグコネクタハウジングのガイド用突起と嵌合し、前記第２のスライダを開状態から閉状態へとスライドさせる過程で前記ガイド用突起を介して前記プラグコネクタハウジングを前記レセプタクルコネクタハウジングに対して嵌合途中位置から完全嵌合位置まで移動させる第２ガイド孔が形成されていることを特徴とする。
【０００８】
この発明によれば、従来のスライダ等の補助機構の代わりにガイド用突起をプラグコネクタハウジングに備えると共にこのガイド用突起が移動するスリット部及びガイド用突起を移動させる複数のスライダをレセプタクルコネクタハウジングに備え、複数のスライダのうちの第１のスライダで両コネクタハウジングを嵌合途中位置まで移動させ、第２のスライダで嵌合途中位置から完全嵌合位置まで移動させるため、１つのスライダで補助機構を構成していた場合に比べ、スライダの長さを短くしスライダを動かすスペースを少なくすることができる。これにより、スライダの大型化を図らずにスライダによる挿入力を大きくすることができ、スライダ付き低挿入力コネクタ全体の大きさを小さくすることができる。
【０００９】
なお、例えばガイド用突起が嵌合本体部の一対の対向する側壁にそれぞれ設けられ、スリット部が嵌合部の一対の対向する壁部にそれぞれ設けられ、スライダが嵌合部の一対の対向する壁部を結ぶ方向と直交する方向の一対の対向する壁部にそれぞれアームプレートを有する第１及び第２のスライダから構成されている場合、第１のスライダの複数のアームプレートには、第１ガイド孔及び副ガイド孔がそれぞれ形成され、第２のスライダの複数のアームプレートには、第２ガイド孔がそれぞれ形成されていることが好ましい。
【００１０】
また、第１及び第２のスライダは、嵌合部の壁部の外面を嵌合方向と直交し両側から挟み込む方向に開閉自在に設けられていることが好ましく、第１及び第２のスライダの複数のアームプレートは、アームプレートに対して直交する方向にそれぞれ一部が互い違いに重なる状態で配置されていることが好ましい。
【００１１】
【発明の実施の形態】
以下、添付の図面を参照して、この発明の好ましい実施の形態を説明する。
図１は、この発明の一実施形態に係るスライダ付き低挿入力コネクタを示す外観斜視図、図２は、このスライダ付き低挿入力コネクタを示す一部透過側面図、図３及び図４は、このスライダ付き低挿入力コネクタにおける嵌合動作を説明するための一部透過側面図、図５は、図４のＡ−Ａ´断面図、図６は、図４のＢ−Ｂ´断面図である。
図１及び図２に示すように、スライダ付き低挿入力コネクタ１は、プラグコネクタハウジング１０と、このプラグコネクタハウジング１０と嵌合するレセプタクルコネクタハウジング２０と、このレセプタクルコネクタハウジング２０に、例えば両コネクタハウジング１０，２０の嵌合方向と直交する方向にスライド自在に装着されたスライダを構成する第１及び第２の複数のスライダ３０，４０とから構成されている。プラグコネクタハウジング１０は、側壁９ａ，９ｂを有しこの側壁９ａ，９ｂに沿ってレセプタクルコネクタハウジング２０と嵌合する嵌合本体部１１と、この嵌合本体部１１の両側壁９ａ，９ｂの外面に突設された円柱状のガイド用突起１５とから構成されている。このプラグコネクタハウジング１０には、例えば複数のレセプタクル接続端子４をプラグコネクタハウジング１０内に収容するための複数の端子収容孔１４が形成されている。また、このプラグコネクタハウジング１０には、レセプタクルコネクタハウジング２０との完全嵌合時に両コネクタハウジング１０，２０を係止固定するためのロック機構を後述するロック凹部と共に構成するロック凸部１２を有する弾性係止片１３が形成されている。
【００１２】
一方、レセプタクルコネクタハウジング２０は、壁部８ａ，８ｂを有しこの壁部８ａ，８ｂに沿ってプラグコネクタハウジング１０の嵌合本体部１１が内側に嵌合し、嵌合時に嵌合本体部１１のガイド用突起１５が嵌合方向に移動可能となるように壁部８ａ，８ｂにスリット部２２が形成された縦断面が凹状の嵌合部２１を備えて構成されている。このレセプタクルコネクタハウジング２０には、例えばプラグ接続端子３をレセプタクルコネクタハウジング２０内に収容するための複数の端子収容孔２４（図５参照）が形成されている。また、レセプタクルコネクタハウジング２０には、プラグコネクタハウジング１０との完全嵌合時に両コネクタハウジング１０，２０を係止固定するためのロック機構を上記ロック凸部１２と共に構成するロック凹部２３が形成されている。また、嵌合部２１の壁部８ａ，８ｂには、例えば後述する第１及び第２のスライダのアームプレートを嵌合部２１に取り付けるための複数のスライダリブ２５ａ，２５ｂがそれぞれ突設されている。
【００１３】
スライダは、レセプタクルコネクタハウジング２０の嵌合部２１の壁部８ａ，８ｂの外面側に、例えばそれぞれ両コネクタハウジング１０，２０の嵌合方向と直交する方向に移動する状態のアームプレート３１，４１を有する複数の第１及び第２のスライダ３０，４０から構成されている。この例では、第１及び第２のスライダ３０，４０のアームプレート３１，４１は、それぞれ互いに対向する方向に移動するように嵌合部２１に備えられている。第１のスライダ３０のアームプレート３１には、嵌合時にプラグコネクタハウジング１０の嵌合本体部１１のガイド用突起１５と嵌合し、第１のスライダ３０をレセプタクルコネクタハウジング２０側にスライドさせたときに両コネクタハウジング１０，２０が嵌合途中位置まで嵌合される方向にガイド用突起１５を移動させる第１ガイド孔３２と、この第１ガイド孔３２と連通し両コネクタハウジング１０，２０が完全嵌合される方向にガイド用突起１５を移動可能とさせる副ガイド孔３３とが形成されている。
【００１４】
一方、第２のスライダ４０のアームプレート４１には、嵌合本体部１１のガイド用突起１５と嵌合し、第２のスライダ４０をレセプタクルコネクタハウジング２０側にスライドさせたときに両コネクタハウジング１０，２０が第１のスライダ３０によって移動させられた嵌合途中位置から完全嵌合位置まで嵌合される方向にガイド用突起１５を移動させる第２ガイド孔４２が形成されている。なお、これら第１及び第２のスライダ３０，４０のスライド方向への位置決めは、アームプレート３１，４１にそれぞれ形成された位置決め突起３１ａ，４１ａを有する弾性位置決め片３１ｂ，４１ｂと、嵌合部２１の壁部８ａ，８ｂに備えられたスライダリブ２５ｂに形成された複数の位置決め溝２６とにより行われる。
【００１５】
このように構成されたスライダ付き低挿入力コネクタ１における両コネクタハウジング１０，２０の嵌合動作は、図３及び図４に示すようにして行われる。まず、図３（ａ）に示すように、プラグコネクタハウジング１０の嵌合本体部１１がレセプタクルコネクタハウジング２０の嵌合部２１の内側に嵌り、嵌合本体部１１のガイド用突起１５が嵌合部２１のスリット部２２に挿入されて、第１のスライダ３０のアームプレート３１のプレート突片３４と当接するまで、両コネクタハウジング１０，２０を嵌合する。なお、このアームプレート３１のプレート突片３４は、このような役割の他に、壁部８ａ，８ｂに対して直交する方向に互い違いに配置されたプレート３１，４１の該直交する方向に沿った配置位置を位置決めする役割を担っている。そして、同図（ｂ）に示すように、第１のスライダ３０をレセプタクルコネクタハウジング２０側にスライドさせると、アームプレート３１の第１ガイド孔３２の形状に基づきガイド用突起１５がスリット部２２のスリット形状に沿って両コネクタハウジング１０，２０の嵌合途中位置まで移動され、それに伴い嵌合本体部１１が嵌合部２１の内側の嵌合途中位置まで嵌合される。次に、第２のスライダ４０をレセプタクルコネクタハウジング２０側にスライドさせると、アームプレート３１の副ガイド孔３３及びアームプレート４１の第２ガイド孔４２の形状に基づきガイド用突起１５がスリット部２２のスリット形状に沿って、図４に示すように、両コネクタハウジング１０，２０の嵌合途中位置から完全嵌合位置まで移動され、それに伴い嵌合本体部１１が嵌合部２１の内側の完全嵌合位置まで嵌合されて、両コネクタハウジング１０，２０が完全嵌合される。このとき、図５に示すように、プラグコネクタハウジング１０のレセプタクル接続端子４とレセプタクルコネクタハウジング２０のプラグ接続端子３とが完全嵌合され、図６に示すように、第１及び第２のスライダ３０，４０が嵌合部２１に最も接近した状態で係止固定される。
【００１６】
このように、このスライダ付き低挿入力コネクタ１によれば、両コネクタハウジング１０，２０の嵌合動作において、第１及び第２のスライダ３０，４０を順番にスライドさせて完全嵌合を図るため、従来のように１つのスライダで完全嵌合を図っていた場合に比べ、スライダ１つ当たりのアームプレート３１，４１の長さを短くし動作量を少なくしてスライダの動作スペースを小さくすることができる。これにより、スライダの大型化を図らずにスライダによる挿入力を大きくすることができ、結果的にスライダ付き低挿入力コネクタ１の全体の大きさを小さくすることができる。
【００１７】
なお、この例では、スライダ付き低挿入力コネクタ１の第１及び第２のスライダ３０，４０が嵌合方向と直交する方向であって互いに対向する方向にスライドする場合を説明したが、第１及び第２のスライダ３０，４０が、例えばそれぞれ嵌合方向に対して直交する以外のある所定の角度をもってスライドするようにしても何ら問題はない。また、第１及び第２のスライダ３０，４０のみでなく、更に複数のスライダによりスライダ付き低挿入力コネクタ１のスライダを構成するようにしても良い。
【００１８】
図７は、この発明の他の実施形態に係るスライダ付き低挿入力コネクタを示す外観斜視図、図８は、このスライダ付き低挿入力コネクタを示す一部透過側面図、図９は、このスライダ付き低挿入力コネクタにおける完全嵌合時の状態を示す一部透過側面図、図１０は、図９のＣ−Ｃ´断面図、図１１は、図９のＤ−Ｄ´断面図である。なお、以降において、既に説明した部分と重複する説明は割愛する。
図７〜図１１に示すように、このスライダ付き低挿入力コネクタ２は、レセプタクルコネクタハウジング２０の嵌合部２１の壁部８ａ，８ｂに突設されたスライダリブ２５ａ，２５ｂの対向端部に、それぞれ壁部８ａ，８ｂの外面に沿った方向にスライド溝２７ａ，２８ａが形成され、第１及び第２のスライダ３０，４０のアームプレート３１，４１のスライダリブ２５ａ，２５ｂと対向する端部に、それぞれスライド溝２７，２８と嵌合するスライド突条２７ｂ，２８ｂが形成されて、プレート突片３４の長さが短く形成されている点が、先の例のコネクタ１と相違している。このスライダ付き低挿入力コネクタ２によれば、スライド溝２７ａ，２８ａ及びスライド突条２７ｂ，２８ｂにより、アームプレート３１，４１の壁部８ａ，８ｂに対して直交する方向への互い違いの配置位置が位置決めされる他は、上記スライダ付き低挿入力コネクタ１と同様の効果を得ることができる。
【００１９】
【発明の効果】
以上述べたように、この発明によれば、従来のスライダ等の補助機構の代わりにガイド用突起をプラグコネクタハウジングに備えると共にこのガイド用突起が移動するスリット部及びガイド用突起を移動させる複数のスライダをレセプタクルコネクタハウジングに備え、複数のスライダのうちの第１のスライダで両コネクタハウジングを嵌合途中位置まで移動させ、第２のスライダで嵌合途中位置から完全嵌合位置まで移動させるため、１つのスライダで補助機構を構成していた場合に比べ、スライダの長さを短くしスライダを動かすスペースを少なくすることができる。これにより、スライダの大型化を図らずにスライダによる挿入力を大きくすることができ、スライダ付き低挿入力コネクタ全体の大きさを小さくすることができるという効果を奏する。

It comprises a receptacle connector housing 120 in which a terminal receiving hole (not shown) for receiving a plurality of plug connection terminals 102 is formed, and a lever 130 separately attached to the receptacle connector housing 120. If the number of connection terminals to be connected increases as in the multi-pole connector 100, the contact resistance between the plug connector housing 110 and the receptacle connector housing 120 at the time of fitting / detaching increases, so that the plug connector housing 110 and the receptacle connector housing 120 are inserted at the time of fitting. The force and the pull-out force during disengagement are also higher. Therefore, in order to suppress the insertion force and the withdrawal force, a boosting mechanism such as a lever 130 is provided. For example, a protrusion 111 is formed on the side surface of the plug connector housing 110, and the lever 111 is fitted with the protrusion 111 and A groove 121 for moving the projection 111 to the rear side of the receptacle connector housing 120 is formed, and by moving the lever 130, a lever-type connector is adapted to be fitted / removed by utilizing this principle. Are known. Further, there is known a so-called low insertion force connector with a slider which is provided with an auxiliary mechanism such as a slider (not shown) in place of the lever 130 so that the two can be fitted / removed (for example, Patent Document 1 and 2).
