【０００１】
【発明の属する技術分野】
本発明は、ＦＰＣ（Flexible Printed Circuit）等の複数の端子を一括して接続すると共に、ＦＰＣ等を外れないように保持するプリント配線板用コネクターに関する。
【０００２】
【従来の技術】
ＦＰＣには多数の端子が並列して設けられているが、このようなＦＰＣを基板等に着脱可能に接続する場合には、多数のコンタクトが並列して設けられたプリント配線板用コネクターが使用される。従来のプリント配線板用コネクターは、例えば特開平７−２２０８２９号公報等に開示されているように、コンタクトとＦＰＣの端子とを、操作部材（加圧部材）を介して押圧して圧接（密着）させることによって、多数の端子を一括して接続すると共に、ＦＰＣが外れないように保持している。
【０００３】
【発明が解決しようとする課題】
上述の特開平７−２２０８２９号公報等に開示されたプリント配線板用コネクターでは、操作部材を介してコンタクトとＦＰＣとが圧接されるまで、ＦＰＣは保持されないため、使用者は、一方の手でＦＰＣを仮保持しながら、他方の手で操作部材を操作する必要があり、操作性が悪いという問題があった。また、ＦＰＣと操作部材とが直に当接しており、ＦＰＣが外れる方向と操作部材が解除される方向とが一致しているため、保持性能が十分ではない等の問題があった。
【０００４】
本発明は、このような問題に鑑み、ＦＰＣ等の複数の端子を一括して接続すると共に、ＦＰＣ等を外れないように保持するプリント配線板用コネクターの操作性、保持性能を向上させることを目的とする。
【０００５】
【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本発明の特徴は、ＦＰＣ等の複数の端子を有するプリント配線板の接続端部分が差し込まれる挿入溝を有するハウジングを備え、該ハウジングには前記挿入溝に対して突出後退自在に複数のコンタクトが並列して設けられているとともに、該コンタクトを突出後退させる操作部材が、コンタクトを突出させる接続位置とコンタクトを後退させる解除位置とに移動自在に、設置され、前記操作部材が前記接続位置のとき、前記コンタクトは、前記操作部材に押圧されて前記挿入溝に突出して前記プリント配線板の接続端部分に圧接され、前記操作部材が前記解除位置のとき、前記コンタクトの内の一部のコンタクトが、前記挿入溝に対して突出して前記プリント配線板を仮保持し、残りのコンタクトは、前記挿入溝に対して後退するように構成されているプリント配線板用コネクターにおいて、前記コンタクトはプリント配線板の挿抜方向に長い略直線状に接触部と***作部とを一体に備えるとともにハウジングに対する被固定部を一体に備え、前記接触部と***作部との中間位置が、連結部を介して被固定部と一体化されており、前記操作部材は、横長の棒状に形成され、前記ハウジングの背面側にあって前記解除位置と接続位置とに回動自在に装着され、その回動軸の周りに、カムが設けられ、該カムによって前記接続位置においては前記***作部が押圧されて接触部が挿入溝に突出され、前記解除位置では一部のコンタクトを除いて前記***作部を押圧せずに前記接触部が挿入溝から後退させるようにするとともに、前記一部のコンタクトの***作部を押圧して前記挿入溝に対して接触部を僅かに突出させるようにしたことにある。
【０００６】
なお、前記コンタクトは一対の平行片部と該平行片部間を連結する連結部とからなる略Ｈ字形に一体的に形成され、前記両平行片部の内の一方は、その一端側を接触部とするとともに他端側を***作部として略直線形に連続して形成され、かつ前記両平行片部の他方は、その一端側を被固定部とするとともに他端側を端子部として連続して形成され、該被固定部を前記ハウジングに対して固定させるとともに端子部をハウジングより突出させ、前記操作部材のカムは前記***作部と端子部との間に配置されていることが好ましい。

【０００８】
図１、２に示すように、合成樹脂製のハウジング３０は、偏平な略直方体に形成されており、ハウジング３０には、正面中央部分に、横長の（挿抜方向に対して垂直に長い）挿入溝３１が、ＦＰＣの接続端部分が差し込まれるように、正面側に開口して形成されている。そして、ハウジング３０には、多数の金属製のコンタクト１０、１０…（１０B 、１０A 、１０A …、１０B ）が、挿入溝３１に沿って横方向に並列して装着され、更に、合成樹脂製の操作部材２０が回動自在に装着されており、操作部材２０を回動させると、コンタクト１０、１０…（接触部１２、１２…）が、挿入溝３１に対して突出後退するようになっている。
【０００９】
コンタクト１０は、図３に示すように、略Ｈ字形に一体的に形成された接触部１２、***作部１３、連結部１４、被固定部１５及び端子部１６をもって構成されており、接触部１２と***作部１３とが縦長の（ＦＰＣの挿抜方向に対して平行に長い）略直線形に連続して形成され、被固定部１５と端子部１６とが縦長の略直線形に連続して形成され、４者の間が略Ｓ字形の連結部１４により連結されている。
即ち、コンタクト１０は、図３に示すようにＨ字形をかたどる一対の平行片部とその両平行片部間を連結する連結部１４とからなる略Ｈ字形に一体的に形成され、前記両平行片部の内の一方は、その一端側を接触部１２とするとともに他端側を***作部１３として略直線形に連続して形成され、かつ前記両平行片部の他方は、その一端側を被固定部１５とするとともに他端側を端子部１６として連続して形成されており、略直線形に連続して形成された接触部１２と***作部１３との中間位置が連結部１４を介して被固定部１５と一体となっている。
なお、多数のコンタクト１０、１０…は、全て同一形状に形成されている。
【００１０】
そして、ハウジング３０には、正面上寄部分に、挿入溝３１の上面側に連通した多数の縦長の後退用凹部３２、３２…が、横方向に並列して設けられており、正面下寄部分に、多数の縦長の固定孔３５、３５…が、横方向に並列して設けられている。そして、コンタクト１０、１０…は、それぞれ、被固定部１５を固定孔３５に嵌入し、接触部１２を後退用凹部３２に挿入して、ハウジング３０に装着されており、***作部１３、端子部１６はハウジング３０の背面側から外部に突出している。
【００１１】
操作部材２０は、図１に示すように、横長の棒状に形成され、両側端に凸形の被支持部２７、２７が設けられている。そして、ハウジング３０の背面両側端部分には、凹形の支持部３７、３７が設けられており、操作部材２０は、被支持部２７を支持部３７に挿入してハウジング３０の背面側に装着され、横向の回動軸Ｘを中心にして、図３に示す解除位置と図４に示す接続位置とに回動自在になっている。また、操作部材２０には、つまみ２５が、回動軸Ｘから突出して設けられており、使用者が指先で容易に回動させることができるようになっている。
【００１２】
そして、操作部材２０には、回動軸Ｘの周りに、カム２３（２３A 、２３B ）が設けられており、カム２３は、コンタクト１０の***作部１３と端子部１６との間に配置され、操作部材２０が接続位置のとき、図４に示すように、カム２３は、コンタクト１０の***作部１３を上方に押圧し、その接触部１２を挿入溝３１に対して下方に突出させるようになっている。また、解除位置では、図３に示すように、中央部分のカム２３A は、***作部１３を押圧せず、接触部１２を挿入溝に対して上方へ後退させるようになっており、一方、両側端のカム２３B は、***作部１３を僅かに上方に押圧して、接触部１２を挿入溝３に対して僅かに下方へ突出させようになっている。
【００１３】
また、図１、２に示すように、ハウジング３０の正面両側端部分には、固定部材４０、４０が、底面側に突出して固定されており、ハウジング３０は、固定部材４０、４０を基板に半田付することによって基板に固定されるようになっている。また、ハウジング３０の背面側に突出したコンタクト１０、１０…の端子部１６、１６…は、それぞれ基板上の配線に半田付により接続されるようになっている。
【００１４】
このように構成されるプリント配線板用コネクターによりＦＰＣを接続するには、図３に示すように、操作部材２０を解除位置にした状態で、ＦＰＣの接合端部分を挿入溝３１に差し込む。この際、中央部分の大多数のコンタクト１０A 、１０A …は、接触部１２を挿入溝３１に対して上方に後退させているが、両側端のコンタクト１０B 、１０B は、カム２３B により***作部１３が押圧されて、接触部１２を挿入溝３１に対して僅かに下方に突出させているので、コンタクト１０B 、１０B の接触部１２とＦＰＣとが軽く当接して（コンタクト１０B 、１０B の接触部１２と挿入溝３１の内底面との間にＦＰＣが軽く挾まれて）、ＦＰＣが仮保持される。
【００１５】
次に、図４に示すように、使用者が指先で操作部材２０を接続位置に回動させるが、この際、上述のようにＦＰＣは仮保持されているので、ＦＰＣを手で押えておく必要がなく、操作部材２０を容易に操作することができる。
【００１６】
操作部材２０を接続位置にすると、全てのコンタクト１０、１０…が、カム２３により***作部１３が押圧されて、接触部１２を挿入溝３１に対して下方に突出させ、全てのコンタクト１０、１０…の接触部１２とＦＰＣの端子とが強固に圧接して（コンタクト１０、１０…の接触部１２と挿入溝３１の底面との間にＦＰＣが強固に挾まれて）、ＦＰＣの多数の端子が一括して接続されると共に、ＦＰＣが確実に保持される。この際、操作部材２０とＦＰＣとは直に接触していないので、ＦＰＣに外力が作用しても操作部材２０が解除されることはなく、十分な保持性能を発揮する。
【００１７】
なお、ＦＰＣを取り外す際には、図３に示すように、使用者が指先で操作部材２０を解除位置に回動させる。すると、中央部分の大多数のコンタクト１０A 、１０A …は、接触部１２を挿入溝３１に対して上方に後退させ、両側端のコンタクト１０B 、１０B のみが、接触部１２を挿入溝３１に対して僅かに下方に突出させた状態になるので、ＦＰＣの接続端部分を挿入溝３１から引き出すようにして、ＦＰＣを容易に取り外すことができる。
【００１８】

【００１９】
なお、複数のコンタクトを、同一形状に形成し、操作部材に、複数のカムを、接続位置のとき、コンタクトを押圧して挿入溝に対して突出させ、解除位置のとき、一部のコンタクトを押圧して挿入溝に対して僅かに突出させ、残りのコンタクトを挿入溝に対して後退させるように設けることによって、上述のような構成を好適に実現できると共に、多数のコンタクトの組立ミスの防止等を図ることができる。
