Description

【０００１】
【発明の属する技術分野】
本発明は、ＦＰＣやＦＣＣ等のフレキシブル板状電線と、プリント配線基板とを接続するフレキシブル板状電線接続用コネクタに関する。
【０００２】
【従来の技術】
従来、ＦＰＣやＦＣＣ等のフレキシブル板状電線をプリント配線基板に接続させるには、フレキシブル板状電線が可撓性を有する為にＺＩＦ（ゼロインフォース）構造を有するフレキシブル板状電線接続用コネクタを介して接続するようにし、少ない挿入力で好適にフレキシブル板状電線の端子部をコネクタに挿入できるようにしており、このようなフレキシブル板状電線接続用コネクタとして、図１１に示す如きものが提供されている（特許文献１を参照）。
【０００３】
このフレキシブル板状電線接続用コネクタ１は、接続しようとするフレキシブル板状電線２の端子部が挿入される板状電線挿入部３を有するハウジング４と、板状電線挿入部３内に突出する弾性接触部５ａ、６ａを有し、プリント配線基板７に接続される複数のコンタクト５，６と、板状電線挿入部３に挿抜自在なスライダー８と、ハウジング４に回動自在に支持され、スライダー８を従動させるカム部９を有する操作レバー１０とを備え、操作レバー１０を回動させることにより、カム部９の動作にスライダー８を従動させ、板状電線挿入部３に挿入された位置と、板状電線挿入部から抜け出た位置との間で進退させることができ、フレキシブル板状電線とともにスライダーが板状電線挿入部に挿入された位置では、フレキシブル板状電線２の端子部をコンタクトの弾性接触部５ａ，６ａと弾性的に接触させ、スライダー８が板状電線挿入部より抜け出た位置では、少ない挿入力で好適にフレキシブル板状電線の端子部をコネクタに挿入できるようになっている。

【０００５】
【発明が解決しようとする課題】
しかし、上述のような従来の技術では、コネクタ全体が小型化されると、コンタクトも小型化され、フレキシブル板状電線に対するコンタクトの接触圧が減少するので、十分な保持力が得られず、フレキシブル板状電線が板状電線挿入部より抜けやすくなるという問題があった。特に、コンタクトの接触部にＡｕメッキが施されている場合、フレキシブル板状電線とコンタクトとの間の摩擦係数が小さくなるのでより抜けやすくなる。
【０００６】
本発明は、このような従来の技術の状況を鑑み、コネクタ全体が小型化されても、フレキシブル板状電線が容易に抜けることがないフレキシブル板状電線接続用コネクタの提供を目的とする。
【０００７】
【課題を解決するための手段】
上述の如き従来の問題を解決し、所期の目的を達成するための請求項１の発明は、接続しようとするフレキシブル板状電線の端子部が挿入される板状電線挿入部を有するハウジングと、前記板状電線挿入部内に突出する弾性接触部を有する複数のコンタクトと、前記板状電線挿入部に挿抜自在で、該板状電線挿入部に挿入されることにより、前記フレキシブル板状電線の端子部を前記コンタクトの弾性接触部に弾性的に接触させるスライダーとを備え、前記スライダーを、板状電線挿入部に挿入された位置と、板状電線挿入部から抜け出た位置との間で進退させるようにしてなるフレキシブル板状電線接続用コネクタにおいて、前記スライダーは、前記フレキシブル板状電線の両側部に形成された挿抜方向と直交する縁が抜き出し方向で当て止めされる抜け止め片と、該抜け止め片の上縁より抜け止め片と直角に突出した押さえ片とを有する板状電線保持部を備え、前記フレキシブル板状電線の側部を前記抜け止め片により抜け止めするとともに、前記押さえ片により前記フレキシブル板状電線の側部を前記押圧板部に対し浮き上がり不能とした状態で板状電線挿入部に対し前記スライダーが挿入されるようにしたことを特徴とする。
【０００８】
このように構成することによって、フレキシブル板状電線がスライダーに保持された状態にあるので、コネクタ全体が小型化されても、フレキシブル板状電線が抜けにくくなる。
【０００９】
請求項２に記載の発明は、請求項１の構成に加え、ハウジングに回動自在に支持された操作レバーを備え、該操作レバーには、スライダーに設けられた従動部に当接するカム部を有し、前記操作レバーを回動させることにより、前記カム部が前記従動部を押圧して、前記スライダーを、板状電線挿入部に挿入された位置と、板状電線挿入部から抜け出た位置との間で進退させるようにしたことを特徴とする。
【００１０】
このように構成することによって、挿入した状態では、スライダが操作レバーにロックされて容易に引き出されることがなく、フレキシブル板状電線の抜き出し方向に対し抜けにくくなる。
【００１１】
請求項３に記載の発明は、請求項１又は２の構成に加え、フレキシブル板状電線の側縁に抜け止め用凹部を形成することを特徴とする。
【００１２】
このように構成することによって、フレキシブル板状電線の両側部に挿抜方向と直交する縁部を好適に形成することができる。
【００１３】
【発明の実施の形態】
次に、本発明に係るフレキシブル板状電線接続用コネクタの実施の形態を図について説明する。尚、上述の従来例と同一の部分には、同一符号を付して説明を省略する。
【００１４】
図１、図２は本発明に係るフレキシブル板状電線接続用コネクタを示し、符号２０はフレキシブル板状電線接続用コネクタ、符号２１はＦＰＣ等のフレキシブル板状電線、符号７は、コネクタが接続されたプリント配線基板である。
【００１５】
フレキシブル板状電線２１は、図３に示すように、可撓性を有し、その端部の一方の面にプリント配線により千鳥状配置に形成された導電パターン２１ａ，２１ａ…からなる端子部が設けられ、フレキシブル板状電線接続用コネクタ２０を介してプリント配線基板７に電気的に接続されるようになっている。
【００１６】
また、このフレキシブル板状電線２１の両側縁部には、抜け止め用凹部２２，２２が形成されている。
【００１７】
プリント配線基板７は、図１２に示す従来例と同様に、表面にプリント配線により千鳥状に配置された接続端子部７ａ，７ａ…を備えて構成されている。
【００１８】
フレキシブル板状電線接続用コネクタ２０は、板状電線挿入部２３を有するハウジング２４と、２種類の複数のコンタクト２５，２６と、板状電線挿入部２３に挿抜自在なスライダー２７と、操作レバー２８とを備え、操作レバー２８を回動させることにより、スライダー２７を、板状電線挿入部２３に挿入された位置と、板状電線挿入部２３から抜け出た位置との間で進退させるようにし、スライダー２７が板状電線挿入部２３から抜け出た位置では、フレキシブル板状電線２１を板状電線挿入部２３に対して小さな力で挿抜できるようになっている。
【００１９】
ハウジング２４は、図４に示すように、絶縁性プラスチック樹脂によって、横長直方体状に形成され、その正面側に開口してフレキシブル板状電線２１が挿入される横長スリット状の板状電線挿入部２３が設けられている。
【００２０】
また、このハウジング２４には、板状電線挿入部２３と連通し、正面側に開口した正面側コンタクト挿入溝２９，２９…と、背面側に開口した背面側コンタクト挿入溝３０，３０…とが設けられ、正面側コンタクト挿入溝２９にコンタクト２５が、背面側コンタクト挿入溝３０にコンタクト２６がそれぞれ挿入されて保持され、２種類のコンタクト２５，２６の接触部が板状電線挿入部２３内にフレキシブル板状電線２１の導電パターンと対応して千鳥配置で突出するようになっている。
【００２１】
ハウジング２４の両側部には、底部３１ａとその両側縁より立ち上げた外側壁部３１ｂ及び取付用突片３１ｃからなるガイド枠３１，３１が、上方に開口し、取付用突片３１ｃをハウジング２４に設けられた取付用孔に圧入することにより、ハウジングの側面に沿って連続した配置となるように取り付けられている。
【００２２】
ガイド枠３１の外側壁部３１ｂには、スライダー２７の外側面に突設されたスライド用突起３２がスライド自在に支持されるスライド用支持溝３３が形成され、このガイド枠３１によって、ハウジング２４に組み込まれたスライダー２７を前後方向にスライド自在に支持するとともに、操作レバー２８を回動自在に抜け止めするようになっている。
【００２３】
また、このガイド枠３１には、外向きに取付片３４が突設され、この取付片３４をプリント配線基板７の取付用パターン７ｂに半田付け等により固着させることにより、フレキシブル板状電線接続用コネクタ全体をプリント配線基板に固定することができるようになっている。
【００２４】
コンタクトは、それぞれ、弾性を有する銅合金等の導電性金属板を二股のフォーク状に打ち抜いて形成されたものを２種類使用する。
【００２５】
コンタクト２５は、図５（ａ）に示すように、先端に接触部３５ａを有する弾性接触片部３５と、弾性接触片部３５と連続配置に形成され、ハウジング２４に取り付けられる固定片部３６と、弾性接触片部３５と二股フォーク状を為すように形成され端部をプリント配線基板の端子部に接続される端子部３７ａとした反力受け用の支持片部３７とを備えている。
【００２６】
一方、コンタクト２６は、図５（ｂ）に示すように、基端側がハウジング２４に保持され、先端側がフレキシブル板状電線の端子部と接触部３８ａで弾性的に接触する弾性接触片部３８と、弾性接触片部３８と二股フォーク状を為すように形成された反力受け用の支持片部３９と、支持片部３９と連続配置に形成されたプリント配線基板に接続する端子片部４０とを備えている。
【００２７】
このコンタクト２５，２６は、コンタクト２５をハウジングの正面側から、コンタクト２６をハウジングの背面側からそれぞれコンタクト挿入溝に挿入し、各接触部３５ａ，３８ａを板状電線挿入部２３内に突出させるようになっている。
【００２８】
スライダー２７は、図６に示すように、絶縁性プラスチック樹脂をもって形成され、板状電線挿入部２３に挿入される平板状の押圧板部４１と、その両側に配置されたスライド腕部４２，４２とを備えて一体に形成され、押圧板部４１が板状電線挿入部２３に対して挿抜自在で、両側のスライド腕部４２，４２がハウジング２４に対してスライド自在に支持されているので、押圧板部４１が板状電線挿入部２３に挿入された位置と、抜け出た位置との間で進退自在となっている。
【００２９】
スライド腕部４２の外側には、ガイド枠３１のスライド用支持溝３３にスライド自在に嵌合するスライド用突起３２が突設され、スライド腕部４２の内側には、従動用凹部４３が形成されている。
【００３０】
この従動用凹部４３の正面側、即ち、スライダー２７の抜け出し方向側縁部には、従動面４４からなる抜け出し方向用従動部が形成され、この抜け出し方向用従動部の内側に段状に切り欠いた形状の逃げ用凹欠部４５が形成されている。
【００３１】
また、従動用凹部４３の背面側、即ち、スライダー２７の挿入方向側縁部には、初動従動面４６及び二次動従動面４７が段状に配置された挿入方向用従動部が形成されている。
【００３２】
また、押圧板部４１は、板状電線挿入部２３に挿抜自在で、板状電線挿入部２３にフレキシブル板状電線の端子部とともに挿入され、フレキシブル板状電線の端子部を下面よりコンタクト２５，２６の接触部３５ａ，３８ａの方向へ押圧するようになっており、押圧板部４１の厚さでコンタクトの撓み量、即ち接触圧を調整することができる。
【００３３】
更に、押圧板部４１は、確認用窓４８，４８…を備え、スライダー２７が板状電線挿入部２３から抜け出た位置にある際に、プリント配線基板７に固着されるコンタクト２５の端子部３７ａ，３７ａ…を視覚可能なようになっている。
【００３４】
また、押圧板部４１の板状電線側面には、フレキシブル板状電線２１の側部を保持する板状電線保持部４９，４９を備え、押圧板部４１は、フレキシブル板状電線２１を保持した状態で板状電線挿入部２３に対し挿抜できるようになっている。
【００３５】
保持部４９は、押圧板部４１の正面側、即ち抜き出し方向側縁部より突出し、フレキシブル板状電線２１の側部に形成された抜き出し方向に対し直角な縁部、即ち凹部２２の先端側縁２２ａが該抜き出し方向で当て止めされる抜け止め片４９ａと、該抜け止め片４９ａの上縁より直角に突出し、前記フレキシブル板状電線の縁部上面を覆う押さえ片４９ｂとを備えている。
【００３６】
フレキシブル板状電線２１は、スライダー２７即ち押圧板部４１が板状電線挿入部２３より引き出された位置で、図７（ａ）に示すように、板状電線保持部４９を抜け止め用凹部２２で避けて押圧板部４１に重ね合わされ、そのまま、抜き出し方向に摺動させると、図７（ｂ）に示すように、先端側縁２２ａが抜け止め片４９ａに当接するとともに、押さえ片４９ｂがフレキシブル板状電線２１の側部、即ちフレキシブル板状電線２１の先端側縁２２ａと連続した部分に被さり、フレキシブル板状電線２１が押圧板部４１に対し浮き上がり不能となり、フレキシブル板状電線２１の両側部が板状電線保持部４９，４９に保持されるようになっている。
【００３７】
一方、フレキシブル板状電線をスライダー２７から取り外す際には、スライダー２７即ち、押圧板部４１を板状電線挿入部２３より引き出した位置で、押圧板部４１に対してフレキシブル板状電線２１を挿入方向にスライドさせてから持ち上げれば、抜け止め用凹部２２により板状電線保持部４９，４９を避けて簡単に外れるようになっている。
【００３８】
操作レバー２８は、図８に示すように、絶縁性プラスチック樹脂をもって全体がコ字状に成形され、横長ロッド状の操作部５０の両側に、一対の回動腕部５１，５１が一体に設けられている。
【００３９】
回動腕部５１には、先端部内側に回動軸５２が突設され、回動軸５２がハウジング外側面に枢支されることにより、操作レバー２８がハウジング２４に対して回動自在に支持されるようになっている。また、回動腕部５１の外側には、スライダー２７を従動させるカム部５３が設けられている。
【００４０】
カム部５３は、それぞれ回動軸中心からの距離が異なる押圧曲面５４ａ，５５ａを有する初動カム５４及び二次動カム５５を備え、初動カム５４と二次動カム５５とは、各押圧曲面５４ａ，５５ａが操作レバー２８の回動半径方向にずれて段差をなすように配置され、その回動半径方向の段差は、スライダーの挿入方向用従動面４６，４７の段差より大きくなっている。
【００４１】
また、初動カム５４の押圧曲面の反対側には、平面状の押圧斜面５４ｂ及び押圧平面５４ｃが連続配置に形成されている。
【００４２】
初動カム５４は、抜け出し方向用従動部に対しては、押圧斜面５４ｂ及び５４ｃが対応する従動面４４に接するようになっており、挿入方向用従動部に対しては、押圧曲面５４ａが対応する初動従動面４６に当接するようになっている。
【００４３】
一方、二次動カム５５は、抜け出し方向用従動部に対しては、逃げ用凹欠部４５を設けたことで、スライダー２７に接触しないようになっており、挿入方向用従動部に対しては、押圧曲面５５ａが対応する二次動従動面４７に当接するようになっている。
【００４４】
次に、このフレキシブル板状電線接続用コネクタの動作状態を図８、図９について説明する。
【００４５】
操作レバー２８を図９（ａ）の位置から正面側、即ち抜け出し方向に回動操作させると、図９（ｂ）に示すように、スライダー２７の抜け出し方向用の従動面４４に初動カム５４の押圧斜面５４ｂが当接し、スライダー２７を抜け出し方向に従動させる。
【００４６】
さらに操作レバー２８を抜け出し方向に回動させると、図９（ｃ）に示すように、初動カム５４の抜け出し方向従動面４４に当接する位置が、押圧斜面５４ｂから押圧平面５４ｃに移行し、押圧平面５４ｃが抜け出し方向従動面４４に当接してスライダー２７を抜け出し方向に従動させる。
【００４７】
そして、初動カム５４の押圧平面５４ｃを従動面４４に当接させた状態で、図９（ｄ）に示すように、操作レバーをハウジング２４に対して斜め方向に起立するまで回動させると、その位置でスライダー２７のスライド用突起３２がスライド用支持溝３３の縁部に当接して、スライドが停止し、スライダー２７は板状電線挿入部２３から抜け出た状態となる。
【００４８】
この状態では、板状電線挿入部２３にスライダーの押圧板部４１が挿入されていないので、板状電線挿入部２３内に突出したコンタクトの接触部３５ａ，３８ａと、その接触部と対向する板状電線挿入部内壁面との間に、フレキシブル板状電線の厚さより広い間隙ができる。
【００４９】
尚、上述のスライダー２７の抜け出し方向の一連の動作において、二次動カム５５は、逃げ用凹欠部４５を設けたことによってスライダー２７に接触しないようになっている。
【００５０】
ここで、フレキシブル板状電線先端部を板状電線挿入部２３に挿入するとともに、抜け止め用凹部２２を板状電線保持部４９に合わせた状態で、フレキシブル板状電線２１をスライダーの押圧板部４１に重ね合わせ、そのまま、フレキシブル板状電線２１を引き抜き方向にスライドさせる。
【００５１】
このようにすると、フレキシブル板状電線２１の抜け止め用凹部２２の先端側縁２２ａが板状電線保持部４９の抜け止め片４９ａに当接するとともに、押さえ片４９ｂがフレキシブル板状電線２１の側部、即ちフレキシブル板状電線２１の先端側縁２２ａと連続した部分に被さり、フレキシブル板状電線２１が押圧板部４１に対し浮き上がり不能となる。
【００５２】
次に、板状電線保持部４９にフレキシブル板状電線２１の側部を保持させた状態で、操作レバー２８を斜めに起立した位置（図１０（ａ））から背面側、即ち挿入方向側に回動動作させると、図１０（ｂ）に示すように、回動半径の小さい初動カム５４の押圧曲面５４ａが挿入方向用初動従動面４６に当接し、スライダー２７を挿入方向へ従動させる。
【００５３】
この状態で操作レバー２８をある位置まで回動させると、図１０（ｃ）に示すように、回動半径の大きい二次動カム５５の押圧曲面５５ａが、挿入方向用二次動従動面４７に当接する。この位置より更に操作レバー２８を回動させると、カム部５３の段差が挿入方向用従動面の段差よりも大きく形成されているため、徐々に初動カム５４の押圧曲面５４ａが挿入方向用初動従動面４６より離れ（図１０（ｄ））、スイッチしたように二次動カム５５の押圧曲面５５ａに挿入方向用二次動従動面４７が押されてスライダー２７を従動させるようになっている。
【００５４】
このように、カム部５３を回動軸中心と押圧曲面との間の距離が異なる初動カム５４と二次動カム５５とにより構成し、回動軸中心と押圧曲面との間の距離が小さいカム５４から順に当接させて、スライダー２７を従動させることにより、カム部５３を一つのカムで構成するよりも長いスライド量を確保することができる。
【００５５】
そして、操作レバー２８をスライダー２７と平行となる位置（図１０（ｅ））まで回動させると、スライダー２７は、押圧板部４１が板状電線挿入部２３内に挿入される前進位置で停止する。
【００５６】
この状態では、板状電線挿入部２３の隙間に挿入されたスライダー２７の押圧板部４１によりフレキシブル板状電線２１は、コンタクトの接触部３５ａ，３８ａの方向に押し付けられ、弾性接触片部３５，３８が撓んでフレキシブル板状電線２１の導電パターンと接触部３５ａ，３８ａとが所定の接触圧で弾性的に接触し、良好な電気接続がなされるとともに、フレキシブル板状電線２１の下面にスライダーの押圧板部４１が密着し、且つ両側部が板状電線保持部に保持された状態にあるのでフレキシブル板状電線２１に引き抜き方向の力が加わっても不用意に抜けることがない。
【００５７】
そして、上記の状態を解除して、フレキシブル板状電線２１を引き抜くには、操作レバー２８を正面側に回動させ、図１０（ａ）に示す状態に戻せば、フレキシブル板状電線２１を小さな力で容易に板状電線挿入部２３より引き抜くことができる。
【００５８】
そして、押圧板部４１を十分に引き出した位置で、フレキシブル板状電線２１を押圧板部４１に対して挿入方向にスライドさせて、フレキシブル板状電線２１を板状電線保持部４９，４９より解除し、そのまま、抜け止め用凹部２２で板状電線保持部４９，４９を回避しながら上方に持ち上げることによって、容易に取り外すことができる。
【００５９】
尚、上述の実施例では、抜け出し方向の動作に関し、初動カム５４のみでスライダー２７を従動させたが、この初動カム５４の代わりに、二次動カム５５のみでスライダー２７を従動させるようにしてもよい。
【００６０】
また、上述の実施例では、従動用凹欠部４３の正面側、即ち、スライダー２７の抜け出し方向側縁部に逃げ用凹欠部４５を設けて、抜け出し方向の一連の動作において、二次動カム５５をスライダー２７に接触させないようにした例について説明したが、逃げ用凹欠部４５の正面側、即ち、スライダー２７の抜け出し方向側縁部を抜け出し方向用の二次動従動面とし、抜け出し方向の動作において、初動カム５４を抜け出し方向従動面４４に当接させて、スライダーを押圧させるのに続けて、二次動カム５５の押圧曲面５５ａとは反対側の平面部を抜け出し方向二次動従動面（逃げ用凹欠部の正面側縁）に当接させ、スライダー２７を順次従動させるようにしてもよい。
【００６１】
また、上述の実施例では、フレキシブル板状電線２１の側部に抜け止め用凹部２２，２２を設け、その抜け止め用凹部２２の先端側縁２２ａをスライダーに設けた板状電線保持部４９で保持させた例について説明したが、フレキシブル板状電線２１の側縁に保持用凸片を一体に突設させ、その保持用凸片の挿入側縁部を抜け止め片に当接させるようにしてもよい。
【００６２】
更に、上述の実施例では、操作レバー２８のカム部５３を回動軸中心と押圧曲面との間の距離が異なる初動カム５４と二次動カム５５とにより構成した例について説明したが、カム部を一つのカムにより構成するようにしてもよい。
【００６３】
【発明の効果】
上述のように、本発明に係るフレキシブル板状電線接続用コネクタは、スライダーに板状電線保持部を備え、フレキシブル板状電線の両側部を該板状電線保持部の保持させた状態で板状電線挿入部に挿入されるようにしたことによって、コネクタ全体を小型化しても、フレキシブル板状電線が抜けにくくなり、安定した接続状態を得ることができる。
【００６４】
また、操作レバーを回動させることにより、カム部が従動部を押圧して、スライダーを、板状電線挿入部に挿入された位置と、板状電線挿入部から抜け出た位置との間で進退させるようにしたことによって、操作レバーがストッパーとして機能し、安定した接続状態を維持することができる。

The press curved surface 55a comes into contact with the corresponding secondary driven surface 47.
[0044]
Next, the operation state of this flexible plate-shaped wire connecting connector will be described with reference to FIGS.
[0045]
When the operation lever 28 is rotated from the position of FIG. 9A to the front side, that is, in the withdrawal direction, the initial cam 54 is moved to the driven surface 44 for the withdrawal direction of the slider 27 as shown in FIG. 9B. The pressing slope 54b comes into contact, and the slider 27 is moved out in accordance with the exit direction.
[0046]
When the operation lever 28 is further rotated in the withdrawal direction, as shown in FIG. 9C, the position of the initial cam 54 that contacts the withdrawal direction driven surface 44 is shifted from the pressing slope 54b to the pressing plane 54c, The flat surface 54c abuts on the exit direction driven surface 44, and the slider 27 is driven in the exit direction.
[0047]
Then, with the pressing plane 54c of the initial motion cam 54 in contact with the driven surface 44, as shown in FIG. 9 (d), when the operation lever is rotated until it rises obliquely with respect to the housing 24, At that position, the slide protrusion 32 of the slider 27 comes into contact with the edge of the slide support groove 33, the slide stops, and the slider 27 comes out of the plate-like electric wire insertion portion 23.
[0048]
In this state, since the pressing plate portion 41 of the slider is not inserted into the plate-like electric wire insertion portion 23, the contact portions 35a and 38a of the contacts protruding into the plate-like electric wire insertion portion 23, and the plate facing the contact portion A gap wider than the thickness of the flexible plate-like electric wire is formed between the inner wall surface of the electric wire insertion portion.
[0049]
In the series of operations in the direction in which the slider 27 is pulled out, the secondary moving cam 55 is prevented from coming into contact with the slider 27 by providing the relief recess 45.
[0050]
Here, the flexible plate-shaped electric wire 21 is inserted into the plate-shaped electric wire insertion portion 23, and the flexible plate-shaped electric wire 21 is moved to the slider pressing plate portion with the retaining recess 22 aligned with the plate-shaped electric wire holding portion 49. The flexible plate-shaped electric wire 21 is slid in the drawing direction as it is.
[0051]
In this way, the leading edge 22a of the retaining recess 22 of the flexible plate-shaped electric wire 21 abuts against the retaining piece 49a of the plate-shaped electric wire holding portion 49, and the pressing piece 49b is a side portion of the flexible plate-shaped electric wire 21. In other words, the flexible plate-shaped electric wire 21 is covered with a portion continuous with the distal end side edge 22 a of the flexible plate-shaped electric wire 21, and the flexible plate-shaped electric wire 21 cannot be lifted with respect to the pressing plate portion 41.

Next, in a state where the side portion of the flexible plate-like electric wire 21 is held by the plate-like electric wire holding portion 49, the operation lever 28 is tilted from the position (FIG. 10A) to the back side, that is, the insertion direction side. 10B, the pressing curved surface 54a of the initial movement cam 54 having a small rotation radius comes into contact with the insertion direction initial movement driven surface 46, and the slider 27 is driven in the insertion direction.
[0053]
When the operating lever 28 is rotated to a certain position in this state, as shown in FIG. 10C, the pressing curved surface 55a of the secondary moving cam 55 having a large turning radius is inserted into the secondary moving driven surface 47 for the insertion direction. Abut. When the operating lever 28 is further rotated from this position, the stepped portion of the cam portion 53 is formed to be larger than the stepped portion of the insertion direction driven surface. The secondary moving driven surface 47 for insertion direction is pushed by the pressing curved surface 55a of the secondary moving cam 55 to switch the slider 27 away from the surface 46 (FIG. 10 (d)).
[0054]
Thus, the cam portion 53 is constituted by the initial motion cam 54 and the secondary motion cam 55 in which the distance between the rotation axis center and the pressing curved surface is different, and the distance between the rotation axis center and the pressing curved surface is small. By bringing the slider 27 into contact with the cam 54 in order, it is possible to secure a longer slide amount than when the cam portion 53 is formed of a single cam.
[0055]
Then, when the operation lever 28 is rotated to a position parallel to the slider 27 (FIG. 10E), the slider 27 stops at an advanced position where the pressing plate portion 41 is inserted into the plate-shaped electric wire insertion portion 23. To do.
[0056]
In this state, the flexible plate-shaped electric wire 21 is pressed in the direction of the contact portions 35a, 38a of the contact by the pressing plate portion 41 of the slider 27 inserted into the gap of the plate-shaped electric wire insertion portion 23, and the elastic contact piece portion 35, 38 is bent, and the conductive pattern of the flexible plate-shaped electric wire 21 and the contact portions 35a, 38a are elastically contacted with a predetermined contact pressure, and good electrical connection is made. Since the pressing plate portion 41 is in close contact and both side portions are held by the plate-like electric wire holding portion, the flexible plate-like electric wire 21 does not come out carelessly even if a force in the pulling direction is applied.
[0057]
And in order to cancel | release said state and pull out the flexible plate-shaped electric wire 21, if the operation lever 28 is rotated to the front side and it returns to the state shown to Fig.10 (a), the flexible plate-shaped electric wire 21 will be small. It can be easily pulled out from the plate-shaped electric wire insertion portion 23 by force.
[0058]
Then, the flexible plate-shaped electric wire 21 is slid in the insertion direction with respect to the pressing plate portion 41 at the position where the pressing plate portion 41 is sufficiently pulled out, and the flexible plate-shaped electric wire 21 is released from the plate-shaped electric wire holding portions 49 and 49. Then, it can be easily removed by lifting it upward while avoiding the plate-like electric wire holding portions 49, 49 with the retaining recess 22.
[0059]
In the above-described embodiment, the slider 27 is driven only by the initial motion cam 54 with respect to the operation in the withdrawal direction, but the slider 27 is driven only by the secondary motion cam 55 instead of the initial motion cam 54. Also good.
[0060]
Further, in the above-described embodiment, the relief recess 45 is provided on the front side of the driven recess 43, that is, the edge of the slider 27 in the exit direction, and the secondary motion is performed in a series of operations in the exit direction. The example in which the cam 55 is not brought into contact with the slider 27 has been described. However, the front side of the escape recess 45, that is, the side edge of the slider 27 in the exit direction is used as a secondary driven surface for the exit direction. In the operation in the direction, the primary cam 54 is brought into contact with the exit direction driven surface 44 and the slider is pressed, and then the flat portion on the opposite side of the pressing curved surface 55a of the secondary motion cam 55 is pulled out in the secondary direction. The slider 27 may be sequentially driven by contacting the driven surface (the front side edge of the relief recess).
[0061]
