Description

【０００１】
【発明の属する技術分野】
本発明は、主として十分な接触力を発揮するバネ性を有してフレキシブル回路基板（ＦｌｅｘｉｂｌｅＰｒｉｎｔｅｄＣｒｉｃｕｉｔ／以下、ＦＰＣとする）を安定して接続するための小型で低背構造のＦＰＣ用コネクタに関する。
【０００２】
【従来の技術】
従来、この種のＦＰＣ用コネクタに関連する周知技術の一例として、特開平９−８２４２７号公報に開示されたフラットケーブル用コネクタの場合、本体がプリント（配線）基板上に実装接続可能に構成されており、具体的にはフラットケーブルの挿入方向を前後方向として上方が開口されたハウジングと、ハウジングの前方から後方に延びてその先端にフラットケーブルと電気的に接触される接点部が設けられた接触片及びリード端子片を有すると共に、固定片を有してハウジングの前方側から取り付けられる第１のコンタクトと、ハウジングの後方から前方に延びてその先端にフラットケーブルと電気的に接触される接点部が設けられた接触片及びリード端子片を有すると共に、固定片を有してハウジングの後方側から取り付けられる第２のコンタクトと、第２のコンタクトの弾性支持片に回動自在に支持されてフラットケーブルを押圧固定するレバー部とを備えた構成とすることにより、各コンタクトをハウジングの前後方向に配備することでコネクタ全体の小型化を図っている。
【０００３】
又、ＦＰＣ用コネクタに関連する周知技術の他例として、特開平８−３１５２６号公報に開示されたラッチ付コネクタの場合、本体がプリント（配線）基板上に実装接続可能に構成される点は同じであるが、ここではプラスチック製のハウジングの前後方向に多数本のコンタクトピンを並設されるように装着し、ハウジングの幅方向片側又は両側にプリント基板又はフレキシブル導体に取り付けた補強板により外側に押し広げられ、且つそれらを所定位置まで押し込むと元の位置に戻ってプリント基板又は補強板を圧着して保持するプラスチック製のラッチを設け、更に、ラッチに加えられる接圧を受けるためにラッチ自体に設けられる補強具に対し、ラッチ，補強具自体のラッチ，ハウジングに取り付けるための装着部、並びにハウジングをセットするプリント基板に固定される支持部を形成した構成とすることにより、ラッチのクリープ変形によるプリント基板及びコンタクトピンの接触不良やプリント基板の挿抜時のラッチの破損を防止した上でコネクタ全体の小型化を図っている。
【０００４】
更に、ＦＰＣ用コネクタに関連する周知技術の別例として、特開平１１−５４２２０号公報に開示されたフレキシブル回路板コネクタの場合、本体がプリント（配線）基板上に実装接続可能に構成される点は同じであるが、ここでは接触部が金属板面として形成されてフレキシブル回路板の一面側に接触可能に千鳥配置される複数のコンタクトを収容した絶縁ハウジングに舌片を有する加圧部材を回動可能に設け、加圧部材における開位置でその両側面のポストと弾性係合片とが係合して絶縁ハウジングに対して抜け止めされ、閉位置でポストと弾性係合片との係合が解除されると共に、係止突起と絶縁ハウジングとが係止し、且つ舌片がコンタクトの一部と係合して絶縁ハウジング上に維持されることでフレキシブル回路板をコンタクトに向けて押圧して電気的接続させる際に十分な接触力を与える構成としている。
【０００５】
【発明が解決しようとする課題】
上述したプリント（配線）基板との接続及びフレキシブルなフラットケーブルとの接続に供されるコネクタの場合、一般に基本機能の確保のために構造上において要求される必要事項として、安定した接触を得るための接触力を具現するために接触バネ片部のバネ長に或る程度の長さが必要とされること、各コンタクトをハウジングに固定するための圧入片部を確保すること、プリント基板と接地される補強金具としての金属部品を取り付けるためのスペースを確保すること等が挙げられるが、これらの必要事項は昨今要求されるコネクタ全体の小型化や低背化（薄型化）を具現する上での妨げとなっているという問題がある。
【０００６】
具体的に言えば、特開平９−８２４２７号公報に開示されたフラットケーブル用コネクタの場合、各コンタクトをハウジングの前後方向に配備することでコネクタ全体の小型化を図っているが、ここでは各コンタクトにおけるプリント基板に対する電気的接続のための脚端子片部がハウジングの両側方向に延びているため、コネクタ全体の外形として安定した接触力を得るための各コンタクトにおける接触バネ片部のバネ長が短くなっており、これによりフラットケーブルに対して安定した接触状態が得られない構造となっているという問題がある。又、ここでのコネクタの場合、各コンタクトにおけるハウジングに固定するための圧入片部を二股に分かれた片部とし、下側又は上側に位置する一方の片部を用いる構造としているため、低背化を具現しようとするとハウジングのモールド厚が薄くなってしまい、これにより機械的強度を十分に確保できなくなってしまうという問題もある。
【０００７】
一方、特開平８−３１５２６号公報に開示されたラッチ付コネクタの場合も、各コンタクトをハウジングの前後方向に配備することでコネクタ全体の小型化を図っているが、ここでも各コンタクトにおけるプリント基板に対する電気的接続を行うための脚端子片部にスペースを要してしまい、接触バネ片部のバネ長を確保しようとすると小型化が困難になってしまうという問題がある他、脚端子片部とは反対側の方向にコンタクトと別個にプリント基板固定用の金属部品（コネクタをプリント基板に安定した姿勢で固定させ、同時にフレキシブル導体の接続強度を向上させるためのもの）を取り付ける必要があるため、この金属部品をハウジングに取り付けるためのスペースがコネクタ全体を小型化したり、低背化（薄型化）する上での妨げとなっているという問題がある。
【０００８】
他方、特開平１１−５４２２０号公報に開示されたフレキシブル回路板コネクタの場合、絶縁ハウジングに舌片を有する加圧部材を回動可能に設けてその閉位置で舌片がフレキシブル回路板をコンタクトに向けて押圧して電気的接続させる際の十分な接触力を与える構成としているが、ここでは加圧部材の舌片がフレキシブル回路板を押圧可能に回動させるためのスペースを背高方向に設ける必要があり、背高方向に或る程度の寸法を確保する必要があるため、この加圧部材の舌片を回動可能にするためのスペースがコネクタ全体を小型化したり、低背化（薄型化）する上での妨げとなっているという問題がある。
【０００９】
本発明は、このような問題点を解決すべくなされたもので、その技術的課題は、十分な接触力を発揮するバネ性を有する小型で低背構造の容易に製造し得るＦＰＣ用コネクタを提供することにある。
【００１０】
【課題を解決するための手段】
本発明によれば、一軸方向に沿って所定の間隔で該一軸方向と垂直な他軸方向に延びて配設された第１のコンタクトを内部に有すると共に、該一軸方向に沿って開口形成された挿入口を有するハウジングと、ハウジングの挿入口近傍に可動に装着されて他軸方向を挿抜方向とするＦＰＣの該挿入口への挿入状態で該ＦＰＣを第１のコンタクトの接触部に対して押圧する押圧可動部材とを備えたＦＰＣ用コネクタにおいて、挿入口における第１のコンタクトの両側にＦＰＣの挿入方向に沿って圧入配設されると共に、少なくとも他軸方向に平板状に延びて該ＦＰＣと接触押圧される接触バネ片部，該接触バネ片部より一軸方向における該挿入口の外方へ向かって平板状に延びた局部から該他軸方向に凸状に突出してハウジングの所定箇所に形成された凹み部に圧入される圧入片部，及び該圧入片部より該一軸方向及び該他軸方向と垂直な別軸方向に延びてプリント基板と接続可能な脚端子片部を一体的に形成した第２のコンタクトを備えたＦＰＣ用コネクタが得られる。
【００１１】
一方、本発明によれば、上記ＦＰＣ用コネクタにおいて、ハウジングは、一主面側に両側壁を有して該両側壁間に段差を成して形成された凹平面部上に第１のコンタクト及び第２のコンタクトの接触バネ片部が配設される一主面側開放形状であり、押圧可動部材は、ハウジングの凹平面部上を覆うように両側壁に対して回動可能に取り付けられることでＦＰＣを挿入する側の一側面の一部を一軸方向に沿って切り欠いて成る切り欠き部が挿入口を形成すると共に、開状態で該挿入口を開放して該ＦＰＣを挿入可能とし、且つ閉状態で該開放された挿入口に挿入されたＦＰＣを第１のコンタクトの接触部に対して押圧する回動開閉式カバー型アクチュエータであるＦＰＣ用コネクタが得られる。
【００１２】
他方、本発明によれば、上記ＦＰＣ用コネクタにおいて、ハウジングは、ＦＰＣを挿入する側の一側面の一部を一軸方向に沿って切り欠いて成る切り欠き部が挿入口を形成する箱型側面開口形状であり、押圧可動部材は、ハウジングの挿入口内に装着されて他軸方向でスライドすると共に、該他軸方向における一方側の開スライド位置で規定される開状態で該挿入口を開放してＦＰＣを挿入可能とし、且つ該他軸方向における他方側の閉スライド位置で規定される閉状態で該挿入口に挿入されたＦＰＣを第１のコンタクトの接触部に対して押圧するスライド開閉式板型アクチュエータであるＦＰＣ用コネクタが得られる。
【００１３】
又、本発明によれば、上記何れかのＦＰＣ用コネクタにおいて、第２のコンタクトの脚端子片部は、圧入片部より別軸方向に延びた局部から屈曲して一軸方向へ平板状に延びてプリント基板の面と平行に接続される平板状部を有するＦＰＣ用コネクタが得られる。
【００１４】
更に、本発明によれば、上記ＦＰＣ用コネクタにおいて、第２のコンタクトは、脚端子片部の平板状部より別軸方向に延びた屈曲部が閉状態にある押圧可動部材を係合保持してハウジングに係止させる係合片部を有するＦＰＣ用コネクタが得られる。
【００１５】
加えて、本発明によれば、上記何れか一つのＦＰＣ用コネクタにおいて、ハウジングは、凹み部を挿入口両側に設けているＦＰＣ用コネクタ、或いは、ハウジングは、凹み部を挿入口内の第１のコンタクトを配設した面壁に形成しているＦＰＣ用コネクタが得られる。
【００１６】
【発明の実施の形態】
以下に実施例を挙げ、本発明のＦＰＣ用コネクタについて、図面を参照して詳細に説明する。
【００１７】
図１は、本発明の一実施例に係るＦＰＣ用コネクタの基本構成をアクチュエータ２の開状態で示した外観斜視図である。又、図２は、このＦＰＣ用コネクタの基本構成をアクチュエータ２の閉状態によるＦＰＣ５の接続状態で示した外観斜視図である。
【００１８】
このＦＰＣ用コネクタの場合、一軸方向に沿って所定の間隔でこの一軸方向と垂直な他軸方向に延びて配設された第１のコンタクト４を内部に有すると共に、一軸方向に沿って開口形成されて第１のコンタクト４の接触部を露呈させた挿入口を有するハウジング１と、ハウジング１の挿入口近傍に可動に装着されて他軸方向を挿抜方向とするＦＰＣ５の挿入口への挿入状態でＦＰＣ５を第１のコンタクト４の接触部に対して押圧する押圧可動部材としてのアクチュエータ２とを備える他、挿入口における第１のコンタクト４の両側にＦＰＣ５の挿入方向に沿って圧入配設されると共に、少なくとも他軸方向に平板状に延びてＦＰＣ５と接触押圧される接触バネ片部，接触バネ片部より一軸方向における挿入口の外方へ向かって平板状に延びた局部から他軸方向に凸状に突出してハウジング１の所定箇所に形成された凹み部に圧入される圧入片部，及び圧入片部より一軸方向及び他軸方向と垂直な別軸方向に延びて図示されないプリント（配線）基板と接続可能な脚端子片部を一体的に形成した左右対称形状の第２のコンタクト３ａ，３ａ′を備えている。
【００１９】
但し、このＦＰＣ用コネクタの場合、ハウジング１は、一主面側に両側壁１ａを有して両側壁１ａ間に段差を成して形成された凹平面部である下面壁１ｂ上に第１のコンタクト４及び第２のコンタクト３ａ，３ａ′の接触バネ片部が配設される一主面側開放形状となっており、押圧可動部材としてのアクチュエータ２は、ハウジング１の凹平面部上を覆うように両側壁１ａに対して回動可能に取り付けられることでＦＰＣ５を挿入する側の一側面の一部を一軸方向に沿って切り欠いて成る切り欠き部が挿入口を形成すると共に、図１に示されるような開状態で挿入口を開放してＦＰＣ５を挿入可能とし、且つ図２に示されるような閉状態で開放された挿入口に挿入されたＦＰＣ５を第１のコンタクト４の接触部に対して押圧する回動開閉式カバー型となっている。
【００２０】
図３は、ここでのＦＰＣ用コネクタに用いられる一形態の第２のコンタクト３ａ，３ａ′における一方側のコンタクト３ａに係る細部構成を示した外観斜視図である。図１，図２において、第１のコンタクト４の右側に配置された第２のコンタクト３ａは、例えば図３に示されるように、ＦＰＣ５の挿抜方向であって、且つ第１のコンタクト４の延在方向である他軸方向に平板状に延びてＦＰＣ５と接触押圧される接触バネ片部３１と、この接触バネ片部３１より第１のコンタクト４の配列方向である一軸方向における挿入口の外方へ向かって同一な平板状に延びた局部から他軸方向に凸状に突出してハウジング１の挿入口両側に形成された凹み部に圧入される圧入片部３２と、この圧入片部３２より一軸方向及び他軸方向と垂直な別軸方向に延びてプリント基板と接続される脚端子片部３３とを一体的に形成した構成となっている。尚、第１のコンタクト４の左側に配置された第２のコンタクト３ａ′の場合、圧入片部３２，脚端子片部３３が接触バネ片部３１に対して一軸方向で反対向きの外方へ形成される点が相違し、これによって第２のコンタクト３ａ，３ａ′は左右対称形として形成されている。
【００２１】
このような構成のＦＰＣ用コネクタの場合、ハウジング１の内部においてプリント基板との接続を行うための第２のコンタクト３ａ，３ａ′をＦＰＣ５との接続を行うための第１のコンタクト４の両側に配置するものとし、これらの第２のコンタクト３ａ，３ａ′をＦＰＣ５の挿入方向に従って圧入装着する構成としているので、全体を小型化及び低背化（薄型化）された構造として容易に製造できる他、ハウジング１の両側壁１ａに対して回動可能に取り付けられたアクチュエータ２の開状態でＦＰＣ５を挿入口より挿入した後、アクチュエータ２を閉状態とすることでアクチュエータ２がハウジング１に係止されるため、挿入されたＦＰＣ５の接続を十分な接触力を発揮するバネ性を有する構造として行うことができる。
【００２２】
図４は、本発明の他の実施例に係るＦＰＣ用コネクタの基本構成をアクチュエータ２の開状態で示した外観斜視図である。又、図５は、このＦＰＣ用コネクタの基本構成をアクチュエータ２の閉状態によるＦＰＣ５の接続状態で示した外観斜視図である。
【００２３】
このＦＰＣ用コネクタの場合、先の一実施例のものと比べ、第１のコンタクト４の左右両側に配置された一形態のコンタクト３ａ，３ａ′に代えてそれぞれ他形態のコンタクト３ｂ，３ｂ′を配置構成した点のみが相違している。
【００２４】
図６は、ここでのＦＰＣ用コネクタに用いられる他形態の第２のコンタクト３ｂ，３ｂ′における一方側のコンタクト３ｂに係る細部構成を示した外観斜視図である。図４，図５において、第１のコンタクト４の右側に配置された第２のコンタクト３ｂは、例えば図６に示されるように、第２のコンタクト３ａの場合と同様にＦＰＣ５の挿抜方向であって、且つ第１のコンタクト４の延在方向である他軸方向に平板状に延びてＦＰＣ５と接触押圧される接触バネ片部３１と、この接触バネ片部３１より第１のコンタクト４の配列方向である一軸方向における挿入口の外方へ向かって同一な平板状に延びた局部から他軸方向に凸状に突出してハウジング１の挿入口両側に形成された凹み部に圧入される圧入片部３２とを有する他、圧入片部３２より別軸方向に延びた局部から屈曲して一軸方向へ平板状に延びてプリント基板の面と平行に接続される平板状部を有する脚端子片部３３′と、この脚端子片部３３′の平板状部より別軸方向に延びて先端が屈曲された屈曲部となっていることで屈曲部が閉状態のアクチュエータ２を係合保持してハウジング１に係止させる係合片部３４とを有し、これらの接触バネ片部３１，圧入片部３２，脚端子片部３３′，係合片部３４を一体的に形成した構成となっている。尚、第１のコンタクト４の左側に配置された第２のコンタクト３ｂ′の場合、圧入片部３２，脚端子片部３３′，及び係合片部３４が接触バネ片部３１に対して一軸方向で反対向きの外方へ形成される点が相違し、これによって第２のコンタクト３ｂ，３ｂ′は左右対称形として形成されている。
【００２５】
即ち、このような構成のＦＰＣ用コネクタの場合も、ハウジング１の内部においてプリント基板との接続を行うための第２のコンタクト３ｂ，３ｂ′をＦＰＣ５との接続を行うための第１のコンタクト４の両側に配置するものとし、これらの第２のコンタクト３ｂ，３ｂ′をＦＰＣ５の挿入方向に従って圧入装着する構成としているので、全体を小型化及び低背化（薄型化）された構造として容易に製造できる他、ハウジング１の両側壁１ａに対して回動可能に取り付けられたアクチュエータ２の開状態でＦＰＣ５を挿入口より挿入した後、アクチュエータ２を閉状態とすることで第１のコンタクト４の両側に配置された第２のコンタクト３ｂ，３ｂ′の係合片部３４の屈曲部がそれぞれアクチュエータ２を係合保持し、この状態でアクチュエータ２がハウジング１に係止されるため、この場合には挿入されたＦＰＣ５の接続を一実施例の場合と比べて一層安定した十分な接触力を発揮するバネ性を有する構造として行うことができる。
【００２６】
図７は、本発明の別の実施例に係るＦＰＣ用コネクタの基本構成をアクチュエータ６の開状態で示した外観斜視図である。又、図８は、このＦＰＣ用コネクタの基本構成をアクチュエータ６の閉状態で示した外観斜視図である。
【００２７】
このＦＰＣ用コネクタの場合、ハウジング１′は、ＦＰＣを挿入する側の一側面の一部を一軸方向に沿って切り欠いて成る切り欠き部が挿入口を形成する箱型側面開口形状となっており、その内部にプリント基板との接続を行うための第２のコンタクト３ｃ，３ｃ′がＦＰＣとの接続を行うための第１のコンタクト４の両側に配置されており、押圧可動部材としてのアクチュエータ６は、ハウジング１′の挿入口内に装着されて挿入口を遮るように他軸方向でスライドすると共に、図７に示されるように他軸方向における一方側の開スライド位置で規定される開状態で挿入口を開放してＦＰＣを挿入可能とし、且つ図８に示されるように他軸方向における他方側の閉スライド位置で規定される閉状態で挿入口に挿入されたＦＰＣを第１のコンタクト４の接触部に対して押圧するスライド開閉式板型となっている。
【００２８】
図９は、ここでのＦＰＣ用コネクタに用いられる別形態の第２のコンタクト３ｃ，３ｃ′における一方側のコンタクト３ｃに係る細部構成を示した外観斜視図である。図７，図８において、第１のコンタクト４の右側に配置された第２のコンタクト３ｃは、例えば図９に示されるように、第２のコンタクト３ａ，３ｂの場合と同様にＦＰＣ５の挿抜方向であって、且つ第１のコンタクト４の延在方向である他軸方向に平板状に延びてＦＰＣ５と接触押圧される接触バネ片部３１と、この接触バネ片部３１より第１のコンタクト４の配列方向である一軸方向における挿入口の外方へ向かって同一な平板状に延びた局部から他軸方向に凸状に突出してハウジング１の挿入口両側に形成された凹み部に圧入される圧入片部３２とを有する他、圧入片部３２より別軸方向に延びた局部から屈曲して一軸方向へ平板状に延びてプリント基板の面と平行に接続される平板状部を有する脚端子片部３３′と、この脚端子片部３３′の平板状部より別軸方向に延びて先端が屈曲された屈曲部となっていることで屈曲部が閉状態のアクチュエータ２を係合保持してハウジング１に係止させる係合片部３４′とを有し、これらの接触バネ片部３１，圧入片部３２，脚端子片部３３′，係合片部３４′を一体的に形成した構成となっている。尚、第１のコンタクト４の左側に配置された第２のコンタクト３ｃ′の場合、圧入片部３２，脚端子片部３３′，及び係合片部３４′が接触バネ片部３１に対して一軸方向で反対向きの外方へ形成される点が相違し、これによって第２のコンタクト３ｃ，３ｃ′は左右対称形として形成されている。
【００２９】
即ち、このような構成のＦＰＣ用コネクタの場合も、ハウジング１′の内部においてプリント基板との接続を行うための第２のコンタクト３ｃ，３ｃ′をＦＰＣとの接続を行うための第１のコンタクト４の両側に配置するものとし、これらの第２のコンタクト３ｃ，３ｃ′をＦＰＣの挿入方向に従って圧入装着する構成としているので、全体を小型化及び低背化（薄型化）された構造として容易に製造できる他、ハウジング１′の挿入口内に挿入口を遮るように他軸方向でスライド可能に取り付けられたアクチュエータ６の開状態でＦＰＣを挿入口より挿入した後、アクチュエータ６を閉状態とすることで第１のコンタクト４の両側に配置された第２のコンタクト３ｃ，３ｃ′における係合片部３４′の屈曲部がそれぞれアクチュエータ６を係合保持し、この状態でアクチュエータ６がハウジング１′に係止されるため、この場合にも挿入されたＦＰＣの接続を一実施例の場合と比べて一層安定した十分な接触力を発揮するバネ性を有する構造として行うことができる。
【００３０】
ところで、上述した各実施例のＦＰＣ用コネクタでは、第２のコンタクト３ａ，３ａ′，３ｂ，３ｂ′，３ｃ，３ｃ′の圧入片部３１をハウジング１，１′の挿入口両側に形成された凹み部に圧入するものとしたが、圧入片部３１を圧入するための凹み部は他所に設けられても良い。
【００３１】
図１０は、上述した図１又は図２に示したＦＰＣ用コネクタに用いた一形態の第２のコンタクト３ａ，３ａ′における一方側のコンタクト３ａ近傍を変形した場合の細部構成を局部を破断して示した外観斜視図である。即ち、ここではコンタクト３ａの圧入片部３１を圧入するための凹み部をハウジング１″の挿入口両側でなく、挿入口内の第１のコンタクト４を配設した下面壁１ｂ′に形成するように変形した構成した様子を示している。こうしたハウジング１″側で凹み部の形成箇所を変形した構成は、その他の第２のコンタクト３ａ′，３ｂ，３ｂ′，３ｃ，３ｃ′の何れの圧入片部３１に対しても同様に適用できるので、ここでの変形した構成は上述した各実施例における第２のコンタクト３ａ，３ａ′，３ｂ，３ｂ′，３ｃ，３ｃ′の何れを備えた場合にも適用できる。
【００３２】
【発明の効果】
以上に説明したように、本発明のＦＰＣ用コネクタによれば、ハウジングの内部においてプリント基板との接続を行うための第２のコンタクトをＦＰＣとの接続を行うための第１のコンタクトの両側に配置するものとし、これらの第２のコンタクトをＦＰＣの挿入方向に従って圧入装着する構成としているので、従来のＦＰＣ用コネクタ関連の既製品と比べて全体を小型化及び低背化された構造として容易に製造できる他、ハウジングの両側壁に対して回動可能に取り付けられたアクチュエータ又はハウジングの挿入口内にスライド可能に取り付けられたアクチュエータの開状態でＦＰＣを挿入口より挿入した後、アクチュエータを閉状態とすることで第２のコンタクトにアクチュエータが係合保持されて挿入されたＦＰＣの接続を十分な接触力を発揮するバネ性を有する構造として行うことができるようになる。
【００３３】
この結果、例えば特開平９−８２４２７号公報に開示されたフラットケーブル用コネクタや特開平８−３１５２６号公報に開示されたラッチ付コネクタの場合にはプリント基板との接続を行うためのコンタクトにおける脚端子片部にスペースを要し、接触バネ片部のバネ性を確保しようとすると全体の小型化が困難になっていたが、本発明のＦＰＣ用コネクタの場合、第２のコンタクトにおける脚端子片部と接触バネ片部との延在方向が異なっているため、接触バネ片部の長さ（バネ性）を十分に確保した上で一層小型化を図ることができる。
【００３４】
又、本発明のＦＰＣ用コネクタの場合、第２のコンタクトにおける圧入片部は、接触バネ片部と隣り合って位置され、ハウジングの挿入口両側や第１のコンタクトを配設した面壁に形成された凹み部に圧入されるため、従来よりも一層低背化を図ることができる。
【００３５】
更に、例えば特開平８−３１５２６号公報に開示されたラッチ付コネクタの場合のように、コンタクトが片側方向にのみ配列された構成ではコネクタをプリント基板に安定した姿勢で固定したり、或いはフレキシブル導体との接続強度を向上させるために別途に補強金具を必要としていたが、本発明のＦＰＣ用コネクタの場合、第２のコンタクトにおける脚端子片部が接触バネ片部や第１のコンタクトと異なる位置に配置されており、しかもプリント基板の面と平行に接続される平板状部を有するため、補強金具を要すること無く接地面積を十分に確保した上でコネクタを安定した姿勢でプリント基板上に実装接続することができる。
【００３６】
加えて、本発明のＦＰＣ用コネクタの場合、第２のコンタクトにおける係合片部は、その先端側の屈曲部がＦＰＣを第１のコンタクトに押圧するための押圧可動部材としてのアクチュエータを確実に係合保持してハウジングに係止させるため、ＦＰＣの接続を安定した十分な接触力を持って行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a small and low-profile FPC connector that has a spring property that exerts a sufficient contact force and stably connects a flexible printed circuit board (hereinafter referred to as an FPC). .
[0002]

[Problems to be solved by the invention]
In the case of a connector provided for connection to the above-described printed (wiring) board and connection to a flexible flat cable, in order to obtain stable contact as a necessary item in general for ensuring basic functions. The spring length of the contact spring piece part needs to be a certain length in order to realize the contact force, secure the press-fitting piece part for fixing each contact to the housing, and the printed circuit board and the ground To secure a space for mounting metal parts as reinforcing metal fittings, etc., but these necessary items are necessary to realize the miniaturization and low profile (thinning) of the connector as required recently. There is a problem that is hindering.
[0006]
Specifically, in the case of a flat cable connector disclosed in Japanese Patent Laid-Open No. 9-82427, the contacts are arranged in the front-rear direction of the housing to reduce the size of the entire connector. Since the leg terminal piece for electrical connection to the printed circuit board at the contact extends in both sides of the housing, the spring length of the contact spring piece at each contact to obtain a stable contact force as the outer shape of the entire connector is There is a problem that the structure is not shortened so that a stable contact state with the flat cable cannot be obtained. Further, in the case of the connector here, the press-fitting piece for fixing to the housing in each contact is a two-part divided piece, and one piece located on the lower side or the upper side is used. If it is going to embody, there will be a problem that the mold thickness of the housing becomes thin, which makes it impossible to secure sufficient mechanical strength.
[0007]
On the other hand, in the case of a connector with a latch disclosed in Japanese Patent Application Laid-Open No. 8-31526, the entire connector is reduced in size by arranging each contact in the front-rear direction of the housing. In addition to the problem that the leg terminal piece for making electrical connection to the space requires a space, and it is difficult to reduce the size if the spring length of the contact spring piece is secured. Because it is necessary to attach the metal parts for fixing the printed circuit board separately from the contacts in the opposite direction (to fix the connector to the printed circuit board in a stable posture and at the same time improve the connection strength of the flexible conductor) , The space for attaching this metal part to the housing hinders the miniaturization of the entire connector and the reduction in height (thinning). There is a problem going on.
[0008]
On the other hand, in the case of the flexible circuit board connector disclosed in Japanese Patent Application Laid-Open No. 11-54220, a pressure member having a tongue piece is rotatably provided on the insulating housing, and the tongue piece contacts the flexible circuit board in the closed position. It is configured to give a sufficient contact force when it is pressed and electrically connected, but here a space is provided in the height direction for the tongue piece of the pressure member to turn the flexible circuit board so that it can be pressed. Since it is necessary to secure a certain dimension in the height direction, the space for enabling the tongue of the pressure member to be rotated is reduced in size or reduced in height (thinner). There is a problem that it is a hindrance to
[0009]

【The invention's effect】
As described above, according to the FPC connector of the present invention, the second contact for connecting to the printed board inside the housing is provided on both sides of the first contact for connecting to the FPC. Since these second contacts are press-fitted and installed in accordance with the FPC insertion direction, the entire structure is easily reduced in size and height compared to existing FPC connector-related products. In addition, the actuator is closed after the FPC is inserted through the insertion port in the open state of the actuator that is pivotably attached to the both side walls of the housing or the actuator that is slidably mounted in the insertion port of the housing. By doing so, the connection of the FPC inserted with the actuator being engaged and held by the second contact is sufficiently connected. It is possible to perform a structure having a spring property to exert force.
[0033]
As a result, for example, in the case of a flat cable connector disclosed in Japanese Patent Laid-Open No. 9-82427 or a connector with a latch disclosed in Japanese Patent Laid-Open No. 8-31526, the legs in the contacts for connecting to the printed circuit board If the terminal piece portion requires a space and the spring property of the contact spring piece portion is to be secured, it has been difficult to reduce the overall size. However, in the case of the FPC connector of the present invention, the leg terminal piece in the second contact Since the extending direction of the contact spring piece portion is different from that of the contact spring piece portion, it is possible to further reduce the size of the contact spring piece portion while ensuring a sufficient length (spring property).
[0034]
In the FPC connector according to the present invention, the press-fit piece portion of the second contact is located adjacent to the contact spring piece portion, and is formed on the side wall of the housing where the first contact is provided, on both sides of the insertion port of the housing. Since it is press-fitted into the recessed portion, it is possible to further reduce the height as compared with the prior art.
[0035]
Further, for example, in the configuration in which the contacts are arranged only in one side direction as in the case of the connector with a latch disclosed in Japanese Patent Laid-Open No. 8-31526, the connector is fixed to the printed circuit board in a stable posture, or a flexible conductor However, in the case of the FPC connector according to the present invention, the leg terminal piece portion of the second contact is different from the contact spring piece portion and the first contact. In addition, it has a flat part that is connected in parallel with the surface of the printed circuit board, so that it can be mounted on the printed circuit board in a stable posture while securing a sufficient grounding area without requiring a reinforcing bracket. Can be connected.
[0036]
In addition, in the case of the FPC connector of the present invention, the engaging piece portion of the second contact reliably serves as an actuator as a pressing movable member for the bent portion on the tip side to press the FPC against the first contact. Since it is engaged and held and locked to the housing, the FPC can be connected with a stable and sufficient contact force.
