Description

【０００１】
【発明の属する技術分野】
本発明は、ＦＰＣ（Ｆｌｅｘｉｂｌｅ Ｐｒｉｎｔｅｄ Ｃｉｒｃｕｉｔ）用のコネクタに関する。
【０００２】
【従来の技術】
近年の電子機器、例えば、携帯電話やディジタルカメラ等はダウンサイジングが加速している。こうした電子機器に実装される電子部品やプリント基板間を接続するには、平型柔軟ケーブルであるＦＰＣが使用され、ＦＰＣ用コネクタにも実装密度を上げるべく、実装高さを低くすること（低背化）を含めて超小型化が求められている。
【０００３】
低背化を図りつつ、カバーの開きや撓みを防止してＦＰＣに対する確実な導通を得るＦＰＣ用コネクタが開示されている（例えば、特許文献１）。
【０００４】
前述のＦＰＣ用コネクタにおいては、カバーの回動支軸は、ハウジングに固定される金属製の補強板の案内支持部に、回動自在でかつ、前後にスライド自在に支持される。閉じられた状態のカバーを回動支軸と共に、後方へスライドすると、カバーの係合部が補強板のロック部に深く係合し、カバーの閉じ姿勢が確実にロックされる。
【０００５】
【特許文献１】
特開２０００−２５２０６７号公報
【０００６】
【発明が解決しようとする課題】
電子機器内のプリント基板と電子部品をＦＰＣで接続する場合に、一方のプリント基板に一対のＦＰＣで接続する場合がある。この場合、従来は、各々のＦＰＣに対して、プリント基板にＦＰＣ用コネクタを二つプリント基板に実装していた。しかし、これでは、ＦＰＣ用コネクタでプリント基板の実装面積が奪われてしまう。
【０００７】
また、前記一対のＦＰＣの導線数（心線数）が少ない場合は（例えば、２心×２心）、従来のＦＰＣ用コネクタは個々の導線を個々の接触子が挟着していたので、個々の接触子の保持力は限界があり心線数が少ないと、ＦＰＣの抜け防止に対して合計の摩擦力が不足してしまい、ＦＰＣのコネクタからの抜けを防止する確実な機構が求められていた。
【０００８】
さらには、ＦＰＣの導線数（心線数）が少ない場合は、ＦＰＣの端末への挿入幅が狭く、ＦＰＣ用コネクタの接触子への位置合わせが容易ではないという問題もある。
【０００９】
本発明は、上述した課題を解決すべく、実装面積が少なく、ＦＰＣがＦＰＣ用コネクタから容易に抜けることが無く、しかも、接触子への位置合わせが容易なＦＰＣ用コネクタおよびこれを用いた携帯電話機を提供することを目的とする。
【００１０】
【課題を解決するための手段】
発明者は、上記目的を満たすため、鋭意研究を重ね新たなＦＰＣ用コネクタおよびこれを用いた携帯電話機を発明した。
【００１１】
より具体的には、本発明は、以下のようなものを提供する。
【００１２】
（１） 電線対プリント基板接続用コネクタにおいて電線にＦＰＣを用いたＦＰＣ用コネクタであって、一対となったＦＰＣが接続されることを特徴とするＦＰＣ用コネクタ。
【００１３】
（２） 端末差込口を有し、電線対プリント基板接続用コネクタにおいて電線にＦＰＣを用いたＦＰＣ用コネクタであって、第１のＦＰＣは第１の平面端末を有し、第２のＦＰＣは第２の平面端末を有し、前記第１の平面端末と前記第２の平面端末とが同一平面上に一対の状態で前記端末差込口に並列配置されて前記第１のＦＰＣと前記第２のＦＰＣとがＦＰＣ用コネクタに接続されていることを特徴とする（１）記載のＦＰＣ用コネクタ。
【００１４】
（２）記載の発明によれば、「（１）記載のＦＰＣ用コネクタにおいて、端末差込口を有し、電線対プリント基板接続用コネクタにおいて電線にＦＰＣを用いたＦＰＣ用コネクタであって、第１のＦＰＣは第１の平面端末を有し、第２のＦＰＣは第２の平面端末を有し、前記第１の平面端末と前記第２の平面端末とが同一平面上に一対の状態で前記端末差込口に並列配置されて前記第１のＦＰＣと前記第２のＦＰＣとがＦＰＣ用コネクタに接続されている」ので、二つのＦＰＣ用コネクタを並列配置した場合と比べて、一つのＦＰＣ用コネクタには中央の仕切りが不要となり、ＦＰＣ用コネクタの実装面積を小さくできる。
【００１５】
（３） 前記端末差込口が形成されている絶縁性のソケットハウジングと、前記端末差込口に臨むように前記ソケットハウジングに配列されている複数のＣ形ばね状接触子と、前記端末差込口を開閉するように前記ソケットハウジングに回転結合されていると共に、前記端末差込口を閉じた状態では前記複数のＣ形ばね状接触子を加圧して当該Ｃ形ばね状接触子と第１の平面端末または第２の平面端末とを接続させる絶縁性のカバーハウジングと、を備えるＦＰＣ用コネクタであって、前記第１の平面端末は、第１の露出導体を有しておりかつ前記端末差込口方向に抗するように第１の方形突起が形成されており、前記第２の平面端末は、第２の露出導体を有しておりかつ前記端末差込口方向に抗するように第２の方形突起が形成されており、前記第１の露出導体と前記第２の露出導体とが各々裏面の状態の場合に、前記第１の方形突起と前記第２の方形突起とが対向するように当該第１の方形突起と当該第２の方形突起とが各々の前記第１の平面端末と前記第２の平面端末とに形成されており、前記第１の方形突起と前記第２の方形突起とが対向するように並列配置されて前記第１のＦＰＣと前記第２のＦＰＣとが前記端末差込口に挿入されたときに前記第１の方形突起と前記第２の方形突起とに当接して挿入方向に対して位置決めさせる中央部突起が前記端末差込口の下面に形成されており、前記カバーハウジングを閉じると前記第１の方形突起と前記第２の方形突起との抜け防止方向に当接する抜け防止突起が前記カバーハウジングの内壁に設けられていることを特徴とする（１）または（２）いずれか記載のＦＰＣ用コネクタ。
【００１６】
（３）記載の発明によれば、「（１）または（２）いずれか記載のＦＰＣ用コネクタにおいて、前記端末差込口が形成されている絶縁性のソケットハウジングと、前記端末差込口に臨むように前記ソケットハウジングに配列されている複数のＣ形ばね状接触子と、前記端末差込口を開閉するように前記ソケットハウジングに回転結合されていると共に、前記端末差込口を閉じた状態では前記複数のＣ形ばね状接触子を加圧して当該Ｃ形ばね状接触子と第１の平面端末または第２の平面端末とを接続させる絶縁性のカバーハウジングとを備えるＦＰＣ用コネクタであって、前記第１の平面端末は、第１の露出導体を有しておりかつ前記端末差込口方向に抗するように第１の方形突起が形成されており、前記第２の平面端末は、第２の露出導体を有しておりかつ前記端末差込口方向に抗するように第２の方形突起が形成されており、前記第１の露出導体と前記第２の露出導体とが各々裏面の状態の場合に、前記第１の方形突起と前記第２の方形突起とが対向するように当該第１の方形突起と当該第２の方形突起とが各々の前記第１の平面端末と前記第２の平面端末とに形成されており、前記第１の方形突起と前記第２の方形突起とが対向するように並列配置されて前記第１のＦＰＣと前記第２のＦＰＣとが前記端末差込口に挿入されたときに前記第１の方形突起と前記第２の方形突起とに当接して挿入方向に対して位置決めさせる中央部突起が前記端末差込口の下面に形成されており、前記カバーハウジングを閉じると前記第１の方形突起と前記第２の方形突起との抜け防止方向に当接する抜け防止突起が前記カバーハウジングの内壁に設けられている」ので、第１のＦＰＣまたは第２のＦＰＣを端末差込口に挿入するときは、第１の方形突起または第２の方形突起が中央部突起に当接して挿入方向に対して位置決めさせる。
【００１７】
カバーハウジングを閉じた状態では、抜け防止突起は端末差込口に形成される切り欠き部に埋設すると共に、抜け防止突起は第１の方形突起または第２の方形突起の後ろ側に位置し、第１の方形突起または第２の方形突起が抜け防止突起に当接することにより、第１のＦＰＣまたは第２のＦＰＣにソケットハウジングから抜ける力が働いても、容易に抜けることはない。
【００１８】
（４） 前記端末差込口の下面は両翼に対向するように立設壁が形成されており、第１の立設壁と前記中央部突起における第１の側壁との第１の間隔は第１の平面端末の幅より僅かに大きく設定されていて第１の端末差込口を形成し、第２の立設壁と前記中央部突起における第２の側壁との第２の間隔は第２の平面端末の幅より僅かに大きく設定されていて第２の端末差込口を形成し、第１の平面端末は第１の端末差込口に挿入され、第２の平面端末は第２の端末差込口に挿入されることを特徴とする（１）から（３）いずれか記載のＦＰＣ用コネクタ。
【００１９】
（４）記載の発明によれば、「（１）から（３）いずれか記載のＦＰＣ用コネクタにおいて、前記端末差込口の下面は両翼に対向するように立設壁が形成されており、第１の立設壁と前記中央部突起における第１の側壁との第１の間隔は第１の平面端末の幅より僅かに大きく設定されていて第１の端末差込口を形成し、第２の立設壁と前記中央部突起における第２の側壁との第２の間隔は第２の平面端末の幅より僅かに大きく設定されていて第２の端末差込口を形成し、第１の平面端末は第１の端末差込口に挿入され、第２の平面端末は第２の端末差込口に挿入される」ので、第１の平面端末を第１の端末差込口に挿入したときは、第１の立設壁と前記中央部突起における第１の側壁が第１の平面端末の幅方向の辺を案内するので挿入が容易となる。
【００２０】
第２の平面端末を第２の端末差込口に挿入したときは、第２の立設壁と前記中央部突起における第２の側壁が第２の平面端末の幅方向の辺を案内するので挿入が容易となる。
【００２１】
（５） 前記カバーハウジングの回転中心からの終端部において相反するように張り出して形成されている弾性突起と、前記端末差込口の両翼に形成されている一対の軸受金具とを備え、前記カバーハウジングを閉じた状態では、前記一対の軸受金具における前面部に前記弾性突起が弾性接触して前記カバーハウジングを前記ソケットハウジングにロックすることを特徴とする（１）から（４）いずれか記載のＦＰＣ用コネクタ。
【００２２】
（５）記載の発明によれば、「（１）から（４）いずれか記載のＦＰＣ用コネクタにおいて、前記カバーハウジングの回転中心からの終端部において相反するように形成されている弾性突起と、前記端末差込口の両翼に形成されている一対の軸受金具とを備え、前記カバーハウジングを閉じた状態では、前記一対の軸受金具における前面部に前記弾性突起が弾性接触して前記カバーハウジングを前記ソケットハウジングにロックする」ので、一対の軸受金具がカバーハウジングを回転支持すると共に、カバーハウジングが容易に開かないように前記弾性突起がばね圧を一対の軸受金具に付勢しているので、しっかりロックされる。
【００２３】
（６） （１）から（５）いずれか記載のＦＰＣ用コネクタが液晶モジュールに実装されており、当該液晶モジュールが搭載されていることを特徴とする携帯電話機。
【００２４】
【発明の実施の形態】
以下に、本発明の実施の形態について図面に基づいて説明する。
【００２５】
図１は、本発明によるＦＰＣと当該ＦＰＣ用コネクタの構成図である。図１は平面図であり、図１において、第１のＦＰＣ１は第１の平面端末１１を有し、第２のＦＰＣ２は第２の平面端末１２を有している。
【００２６】
平面端末１１及び１２は裏面に各々銅箔からなる露出導体１３及び１４を形成している。図１におけるＦＰＣ１及び２はそれぞれ４本の導線数（心線数）となっている。また、第１の平面端末１１の右辺には第１の方形突起１５が形成されており、第２の平面端末１２の左辺には第２の方形突起１６が形成されている。
【００２７】
第１の露出導体１３と第２の露出導体１４とが各々裏面の状態の場合に、方形突起１５と方形突起１６とが対向するように方形突起１５と方形突起１６とが各々の平面端末１１と平面端末１２とに形成されている。
【００２８】
この実施の形態において、ＦＰＣ用コネクタ１００は、絶縁性のソケットハウジング３と絶縁性のカバーハウジング４と複数のＣ形ばね状接触子５で構成されている。
【００２９】
ソケットハウジング３は、平面端末１１及び１２が挿入される端末差込口１０が形成されている。また、複数のＣ形ばね状接触子５は、端末差込口１０に臨むようにソケットハウジング３に配列されている。
【００３０】
カバーハウジング４は、端末差込口１０を開閉するようにソケットハウジング３に回転結合されている。端末差込口１０を閉じた状態では、カバーハウジング４は、複数のＣ形ばね状接触子５を加圧し、複数のＣ形ばね状接触子５と挿入される平面端末１１及び１２を接続させる。
【００３１】
図１の実施の形態においては、ＦＰＣ１及び２の心線数に対応して、複数のＣ形ばね状接触子５は４極ずつが並列配置されている。図１の状態から、第１のＦＰＣ１は、第１の端末差込口１Ａに挿入される。同様に、図１の状態から、第２のＦＰＣ２は、第２の端末差込口１Ｂに挿入される。なお、図１はカバーハウジング４が開いた状態である。
【００３２】
また、端末差込口１０の下面には中央部突起３０が形成されている。さらに、端末差込口１０の下面は両翼に対向するように立設壁６１及び６２が形成されている。さらに、端末差込口１０の下面前部には、カバーハウジング４における抜け防止突起４０が埋設される切り欠き部３３が形成されている。
【００３３】
第１の立設壁６１と中央部突起３０における第１の側壁３１との第１の間隔は、平面端末１１の幅より僅かに大きく設定されており、第１の端末差込口１Ａを形成している。
【００３４】
また、第２の立設壁６２と中央部突起３０における第２の側壁３２との第２の間隔は、平面端末１２の幅より僅かに大きく設定されており、第２の端末差込口１Ｂを形成している。
【００３５】
引き続き、本発明によるＦＰＣ用コネクタの構成を図２により説明する。図２は一対になった２心線のＦＰＣに対応するＦＰＣ用コネクタ２００の構成図であり、ＦＰＣ用コネクタ２００は２極のＣ形ばね状接触子５を一対有している。
【００３６】
図２（ａ）はＦＰＣ用コネクタ２００の背面図、図２（ｂ）は平面図、図２（ｃ）は正面図、図２（ｄ）は図２（ｃ）の右側面図である。
【００３７】
図２において、カバーハウジング４の回転中心からの終端部では相反するように張り出して弾性突起４１及び４２が形成されている。
【００３８】
そして、一対の軸受金具７１及び７２は、端末差込口１０の両翼に形成されている。軸受金具７１の立設片７１Ａはカバーハウジング４の回転軸８Ａを軸止し、軸受金具７２の立設片７２Ａはカバーハウジング４の回転軸８Ｂを軸止する。軸受金具７１の平面片７１Ｂと、軸受金具７２の平面片７２Ｂとは、それぞれ、このソケットハウジング３が実装される後述するプリント基板９上に例えば、ハンダ付け等で固定される。
【００３９】
一方、カバーハウジング４を閉じた状態では、立設片７１Ａ及び７２Ａにおけるそれぞれの前面部が弾性突起４１及び４２に弾性接触して、カバーハウジング４をソケットハウジング３にロックする。カバーハウジング４を弾性突起４１及び４２の押し付け力に抗して引き上げることにより、カバーハウジング４を開くことができる。
【００４０】
次に、カバーハウジング４の動作を図３の状態変化図により説明する。図３は図２（ｂ）のＸ−Ｘ矢視断面図であり、図３（ａ）はカバーハウジング４が開いた状態図、図３（ｂ）はカバーハウジング４が閉じる途中の状態図、図３（ｃ）はカバーハウジング４が閉じた状態図である。
【００４１】
図３（ａ）においては、Ｃ形ばね状接触子５の上腕５Ａの先端部が、カバーハウジング４に形成されたリブ４Ａに下向きの力が付勢しているので、カバーハウジング４は立直状態（開いた状態）を維持している。
【００４２】
図３（ａ）の状態からカバーハウジング４を反時計方向に回転すると、図３（ｂ）の状態に移行する。
【００４３】
図３（ｃ）は、カバーハウジング４が完全に閉じられた状態である。図３（ｃ）の状態においては、Ｃ形ばね状接触子５の下腕５Ｂの先端部が露出導体１４に圧接する。一方、平面端末１２をリブ４Ａで押さえているので、適正圧力でＣ形ばね状接触子５とＦＰＣ１及び２の導体線は接続する。
【００４４】
なお、図３において、符号８と符号８Ｃはカバーハウジング４の補強軸であり、補強軸８の両終端部は図２における回転軸８Ａ及び８Ｂとなっている。また、図３において、Ｃ形ばね状接触子５の接続端５Ｃは、プリント基板９の座パターンにハンダ付けで固定される。
【００４５】
ソケットハウジング３は、Ｃ形ばね状接触子５がプリント基板９に固定されるのである。また、プリント基板９は例えば、電子機器に搭載される液晶モジュールの構成部品である。
【００４６】
次に、本発明の作用を図４により説明する。図４はＦＰＣ１及び２がソケットハウジング３に挿入された状態図である。
【００４７】
図４において、第１のＦＰＣ１における方形突起１５と、第２のＦＰＣ２における方形突起１６とが対向するように端末差込口１０に挿入させる。
【００４８】
図４において、第１のＦＰＣ１の平面端末１１は、中央部突起３０における第１の側壁３１と立設壁６１に案内されて、端末差込口１０に挿入される。同様に、第２のＦＰＣ２の平面端末１２は、中央部突起３０における第２の側壁３２と立設壁６２に案内されて、端末差込口１０に挿入される。
【００４９】
平面端末１１及び１２はそれぞれ一定の距離を進むと、ＦＰＣ１及び２にそれぞれ形成された方形突起１５及び１６が中央部突起３０に当接して、進行を停止する。すなわち、方形突起１５及び１６が挿入方向の停止位置決めの機能を有している。この場合、ＦＰＣ１とＦＰＣ２を同時に挿入することも可能であり、個別に挿入することも可能としている。
【００５０】
次に、カバーハウジング４を閉じると、図３に示されるように、Ｃ形ばね状接触子５が平面端末１１及び１２を挟圧する。また、カバーハウジング４を閉じると、図４に示されるようにカバーハウジング４における抜け防止突起４０が切り欠き部３３に埋設される。
【００５１】
図４において、ＦＰＣ１及び２がＦＰＣ用コネクタ１００及び２００から離れようとする力Ｐが作用すると、方形突起１５及び１６のそれぞれの後端が抜け防止突起４０に当接して、ＦＰＣ１及び２がＦＰＣ用コネクタ１００及び２００から離れようとすることを防止する。
【００５２】
次に、前述のような抜け防止機能を付加した理由を説明する。図３（ｃ）に示されるように、Ｃ形ばね状接触子５は平面端末１１及び１２における各々銅箔からなる露出導体１３及び１４を当圧している。Ｃ形ばね状接触子５が露出導体１３及び１４を圧す力は電気的接続には充分であるが、露出導体１３及び１４を破壊しない程度の弱い力である。
【００５３】
Ｃ形ばね状接触子５の極数（ＦＰＣの導線数）が少ない場合は、ＦＰＣ１及び２のそれぞれにＦＰＣ用コネクタ１００及び２００から抜ける力が働くと、Ｃ形ばね状接触子５の摩擦力ではこれに抗していけないのである。
【００５４】
以上の理由から、ＦＰＣ１及び２に方形突起１５及び１６を形成し、カバーハウジング４に抜け防止突起４０を設けたのである。このような抜け防止機能を必要とするＦＰＣの導線数（心線数）は「５」まで好ましくは「６」までとする。
【００５５】
また、以上説明した対となるＦＰＣ１及び２は導線数が「２×２」または「４×４」などの同数の場合で説明したが、適用されるＦＰＣあるいはこれに適用するＦＰＣ用コネクタは例えば「２×４」、「３×２」、「２×４」等のように異なる線数をもつＦＰＣが対となってもよい。さらには、本発明による技術的思想によればコネクタはＦＰＣに限定されることなくＦＦＣ（Ｆｌｅｘｉｂｌｅ Ｆｌａｔ Ｃａｂｌｅ）に適用することも可能とする。
【００５６】
また、実施例におけるＦＰＣ用コネクタの実寸は横幅が８〜９．５ｍｍ、奥裄が４.７７ｍｍ、高さ０．９ｍｍ程度の超小型コネクタである。本発明は２つのコネクタを一つにまとめたので横幅を特に小さくすることができた。

The cover housing 4 can be opened by pulling up the cover housing 4 against the pressing force of the elastic protrusions 41 and 42.
[0040]
Next, the operation of the cover housing 4 will be described with reference to the state change diagram of FIG. 3 is a cross-sectional view taken along the line XX in FIG. 2B, FIG. 3A is a state diagram in which the cover housing 4 is opened, FIG. 3B is a state diagram in the middle of closing the cover housing 4, FIG. 3C is a state diagram in which the cover housing 4 is closed.
[0041]
In FIG. 3A, the tip of the upper arm 5A of the C-shaped spring-shaped contact 5 is biased downward by a rib 4A formed on the cover housing 4, so that the cover housing 4 is in the upright state. (Open state) is maintained.
[0042]
When the cover housing 4 is rotated counterclockwise from the state of FIG. 3A, the state shifts to the state of FIG.
[0043]
FIG. 3C shows a state where the cover housing 4 is completely closed. In the state of FIG. 3C, the tip of the lower arm 5B of the C-shaped spring-shaped contact 5 is in pressure contact with the exposed conductor. On the other hand, since the flat terminal 12 is pressed by the rib 4A, the C-shaped spring contact 5 and the conductor wires of the FPCs 1 and 2 are connected with an appropriate pressure.
[0044]
In FIG. 3, reference numerals 8 and 8C are reinforcing shafts of the cover housing 4, and both end portions of the reinforcing shaft 8 are rotating shafts 8A and 8B in FIG. In FIG. 3, the connection end 5 </ b> C of the C-shaped spring-like contact 5 is fixed to the seat pattern of the printed circuit board 9 by soldering.
[0045]
In the socket housing 3, the C-shaped spring contact 5 is fixed to the printed circuit board 9. The printed circuit board 9 is a component part of a liquid crystal module mounted on an electronic device, for example.
[0046]
Next, the operation of the present invention will be described with reference to FIG. FIG. 4 is a state diagram in which the FPCs 1 and 2 are inserted into the socket housing 3.
[0047]
In FIG. 4, the rectangular protrusion 15 in the first FPC 1 and the rectangular protrusion 16 in the second FPC 2 are inserted into the terminal insertion port 10 so as to face each other.
[0048]
In FIG. 4, the flat terminal 11 of the first FPC 1 is guided by the first side wall 31 and the standing wall 61 in the central protrusion 30 and inserted into the terminal insertion port 10. Similarly, the planar terminal 12 of the second FPC 2 is guided by the second side wall 32 and the standing wall 62 in the central projection 30 and inserted into the terminal insertion port 10.
[0049]
When the flat terminals 11 and 12 travel a certain distance, the square protrusions 15 and 16 formed on the FPCs 1 and 2 respectively contact the central protrusion 30 and stop moving. That is, the square protrusions 15 and 16 have a function of stop positioning in the insertion direction. In this case, it is possible to insert FPC1 and FPC2 at the same time, or to insert them individually.
[0050]
Next, when the cover housing 4 is closed, as shown in FIG. 3, the C-shaped spring-shaped contact 5 clamps the flat terminals 11 and 12. Further, when the cover housing 4 is closed, the removal preventing projection 40 in the cover housing 4 is embedded in the notch 33 as shown in FIG.
[0051]
In FIG. 4, when a force P is applied to cause the FPCs 1 and 2 to move away from the FPC connectors 100 and 200, the rear ends of the rectangular protrusions 15 and 16 come into contact with the removal preventing protrusions 40, and the FPCs 1 and 2 are connected to the FPC. This prevents the connector 100 and 200 from being separated.
[0052]
Next, the reason why the above-described omission prevention function is added will be described. As shown in FIG. 3 (c), the C-shaped spring-like contact 5 presses the exposed conductors 13 and 14 made of copper foil at the flat terminals 11 and 12, respectively. The force with which the C-shaped spring-shaped contact 5 presses the exposed conductors 13 and 14 is sufficient for electrical connection, but is weak enough not to break the exposed conductors 13 and 14.
[0053]
When the number of poles of the C-shaped spring-like contactor 5 (the number of FPC conductors) is small, the frictional force of the C-shaped spring-like contactor 5 is exerted when the force of pulling out from the FPC connectors 100 and 200 acts on the FPCs 1 and 2, respectively. Then you can't resist this.
[0054]
For the above reasons, the rectangular projections 15 and 16 are formed on the FPCs 1 and 2, and the removal preventing projection 40 is provided on the cover housing 4. The number of conductors (number of cores) of the FPC that requires such a disconnection preventing function is set to “5”, preferably to “6”.
[0055]
Further, although the paired FPCs 1 and 2 described above have been described in the case where the number of conductors is the same number such as “2 × 2” or “4 × 4”, the FPC to be applied or the FPC connector applied to this is, for example, FPCs having different numbers of lines such as “2 × 4”, “3 × 2”, “2 × 4”, and the like may be paired. Furthermore, according to the technical idea of the present invention, the connector is not limited to the FPC, but can be applied to an FFC (Flexible Flat Cable).
[0056]
In addition, the actual size of the FPC connector in the embodiment is an ultra-small connector having a width of 8 to 9.5 mm, a depth of 4.77 mm, and a height of about 0.9 mm. In the present invention, since the two connectors are combined into one, the lateral width can be particularly reduced.
[0057]
【The invention's effect】

The FPC and the second FPC are connected to the FPC connector. ”Compared to the case where two FPC connectors are arranged in parallel, one FPC connector does not require a central partition. The connector mounting area can be reduced.
[0058]

A plurality of C-shaped spring-shaped contacts and a plurality of C-shaped spring-shaped contacts in a state of being rotationally coupled to the socket housing so as to open and close the terminal insertion port and with the terminal insertion port closed. And an insulating cover housing for connecting the C-shaped spring-like contactor to the first planar terminal or the second planar terminal by pressurizing the C-shaped spring contact, wherein the first planar terminal is The first rectangular protrusion is formed so as to resist the direction of the terminal insertion port, and the second planar terminal includes the second exposed conductor. And the terminal insertion port When the second rectangular protrusion is formed so as to oppose the direction, and the first exposed conductor and the second exposed conductor are in the state of the back surfaces, the first rectangular protrusion and the second The first rectangular protrusion and the second rectangular protrusion are formed on each of the first planar terminal and the second planar terminal so that the rectangular projections of the first planar terminal and the second planar terminal are opposed to each other. When the first FPC and the second FPC are inserted into the terminal insertion port, the first and second rectangular protrusions are arranged in parallel so that the rectangular protrusion and the second rectangular protrusion are opposed to each other. A central protrusion is formed on the lower surface of the terminal insertion port so as to contact the second rectangular protrusion and to be positioned in the insertion direction. When the cover housing is closed, the first rectangular protrusion and the first rectangular protrusion The anti-disengagement protrusion that abuts against the square protrusion of 2 in the direction of anti-detachment is the cover. Since the first FPC or the second FPC is inserted into the terminal insertion slot, the first rectangular protrusion or the second rectangular protrusion is in contact with the central protrusion. Position in the insertion direction.
[0059]
