Description

【０００１】
【発明の属する技術分野】
本発明は、携帯電話やノートパソコンやデジタルカメラ等に使用されるコネクタに関するもので、特にフレキシブルプリント基板（以下「ＦＰＣ」という）やフレキシブルフラットケーブル（以下「ＦＦＣ」という）にコンタクトを押し付ける機構に関するものである。
【０００２】
【従来の技術】
携帯電話やＣＣＤカメラ等に使用されるコネクタは、狭ピッチで極薄（所謂軽薄短小）であり、主にハウジングとコンタクトとスライダーとから構成され、ハウジングとスライダーとでＦＰＣ又はＦＦＣを挟持する構造である。ハウジングとスライダーとでＦＰＣ又はＦＦＣを保持する方法には、色々考えられるが、中でもハウジングにＦＰＣ又はＦＦＣを挿入した後にスライダーを挿入しＦＰＣ又はＦＦＣをコンタクトに押しつける構造のものが多い。
ハウジングには、コンタクトが挿入される所要数の挿入孔が設けられるとともにＦＰＣ又はＦＦＣが挿入される嵌合口が設けられている。
コンタクト６４は図８のように略コ字形状をしており、主にＦＰＣ４０又はＦＦＣと接触する接触部２２と基板等に接続する接続部２４とハウジング６２に固定される固定部４２とから構成されている。このコンタクト６４は、圧入等によってハウジング６２に固定されている。
例えば、スライダー６６は、図８のように略楔形状をしており、所要数のコンタクト６４が配置されたハウジング６２に、ＦＰＣ４０又はＦＦＣを挿入した後に、前記スライダー６６を挿入する。このようなスライダー６６は、主にハウジング６２に装着される装着部７４とＦＰＣ４０又はＦＦＣをコンタクト６４の接触部２２に押圧する押圧部６８とを備えている。ＦＰＣ４０又はＦＦＣが挿入される以前は、スライダー６６はハウジング６２に仮装着された状態になっており、ＦＰＣ４０又はＦＦＣが挿入された後にスライダー６６を挿入すると、図８（Ｂ）のようにＦＰＣ４０又はＦＦＣと平行に前記スライダー６６の押圧部６８が挿入され、コンタクト６４の接触部２２にＦＰＣ４０又はＦＦＣが押圧されるようになる。
【０００３】
【発明が解決しようとする課題】
近年、この種のコネクタ６０には、より低背位化の要求が強くなってきているが、上述した構造のコネクタ６０では、図８（Ｂ）のように６層（ハウジング６２の厚み方向両側の壁・コンタクト６４の接触部２２と受け部７０の厚さ・スライダー６６の押圧部６８の厚さ・ＦＰＣ４０又はＦＦＣの厚さ）構造になっている。低背位化を考えると、コンタクト６４の受け部７０を省略し、５層（ハウジング６２の厚み方向両側の壁・コンタクト６４の接触部２２の厚さ・スライダー６６の押圧部６８の厚さ・ＦＰＣ４０又はＦＦＣの厚さ）構造にすることはできるが、各部位の強度や仕様等からこれ以上低背位化が出来ないといった解決すべき課題があった。
また、上述のような構造のコネクタ６０では、ハウジング６２の嵌合口１８側のみで、ＦＰＣ４０又はＦＦＣの挿入とコンタクト６４の接触部２２をＦＰＣ４０又はＦＦＣに押しつける動作を行っているので、コネクタが小型化すればするほど作業性が悪いと言った問題点もある。
さらにまた、コネクタ６０のピッチの狭小化が要求された場合、従来の構造のようにコンタクト６４を一方向から挿入したのでは、コネクタの狭小化にも限界があった。
【０００４】
本発明は、このような従来の問題点に鑑みてなされたもので、各部位の強度や仕様等を損なうことなく、スライダー１６でＦＰＣ４０又はＦＦＣを確実にコンタクト１４の接触部２２に押圧することができ、作業性がよく、ピッチの狭小化や低背位化が可能なコネクタを提供せんとするものである。
【０００５】
【課題を解決するための手段】
上記目的の低背位化は、ＦＰＣ４０又はＦＦＣと着脱自在に嵌合するコネクタ１０であって、該ＦＰＣ４０又は前記ＦＦＣと接触する接触部２２を有する所要数のコンタクト１４と、このコンタクト１４が保持・固定されるとともに前記ＦＰＣ４０又は前記ＦＦＣが挿入される嵌合口１８を有するハウジング１２と、前記ＦＰＣ４０又は前記ＦＦＣを前記コンタクト１４に押圧するスライダー１６とを備えるコネクタ１０において、前記コンタクト１４の接触部２２と接続部２４との間に弾性部３４と支点部３２とを設けるとともに前記接触部２２と前記弾性部３４と前記支点部３２と前記接続部２４とを略クランク形状に配置し、かつ、前記接続部２４と対向する位置に前記弾性部３４から延設された押受部２０を設け、前記スライダー１６に長手方向に連設した押圧部３６を設け、該押圧部３６が前記コンタクト１４の接続部２２と押受部２０との間で回動自在に前記スライダー１６を前記ハウジング１２に装着することにより達成できる。
【０００６】
上記目的の低背位化とピッチの狭小化は、ＦＰＣ４０又はＦＦＣと着脱自在に嵌合するコネクタ１０１であって、該ＦＰＣ４０又は前記ＦＦＣと接触する接触部２２を有する所要数のコンタクト１４、１４２と、このコンタクト１４、１４２が保持・固定されるとともに前記ＦＰＣ又は前記ＦＦＣが挿入される嵌合口１８を有するハウジング１２１と、前記ＦＰＣ４０又は前記ＦＦＣを前記コンタクト１４、１４２に押圧するスライダー１６１とを備えるコネクタ１０１において、２種類のコンタクト１４、１４２を千鳥に配置し、一方のコンタクト１４には、接触部２２と接続部２４との間に弾性部３４と支点部３２とを設けるとともに前記接触部２２と前記弾性部３４と前記支点部３２と前記接続部２４とを略クランク形状に配置し、かつ、前記接続部２４と対向する位置に前記弾性部３４から延設された押受部２０を設け、もう一方のコンタクト１４２には、接触部２２と接続部２４との間に弾性部３４と支点部３２とを設けるとともに前記接触部２２と前記弾性部３４と前記支点部３２と前記接続部２４とを略コ字状に配置し、かつ、前記弾性部３４から接触部２２と反対方向に延設された押受部２０を設け、前記スライダー１６１に長手方向に連設した押圧部３６を設け、該押圧部３６が一方のコンタクト１４の接続部２４と押受部２０との間及びもう一方のコンタクト１４２の押受部２０と前記ハウジング１２１との間で回動自在に前記スライダー１６１を前記ハウジング１２１に装着することにより達成できる。
【０００７】
一方若しくはもう一方の前記コンタクト１４、１４２の押受部２０の先端に突出部２６を設け、前記スライダー１６１の押圧部３６が一方の前記コンタクト１４の接続部２４方向へ移動しないようにすることが望ましい。このように突出部２６を設けることで、スライダー１６１の押圧部３６をコンタクト１４の押受部２０と接続部２４との間で回動させるときスライダー１６１の回動に対する反発力が強い為に、スライダー１６１の中央部が図６（Ｂ）の矢印「ハ」方向に膨れてしまうことを防ぐことが出来る。
また、前記スライダー１６、１６１の押圧部３６の形状を細長形状にすることが望ましい。例えば、楕円形にすると良い。このように細長形状にすることで、前記スライダー１６、１６１を回動した際に、確実に前記コンタクト１４、１４１、１４２の押受部２０を上方に押し上げ、接触部２２をＦＰＣ４０又はＦＦＣに容易に接触させることができる。
【０００８】
前記スライダー１６、１６１には、所要数の前記コンタクト１４、１４１、１４２の突出部２６と係合する係止孔３０を設け、該係止孔３０を別個独立にした方がよい。このように前記係止孔３０を別個独立にすることで、前記スライダー１６、１６１を強固で、確実に回動することができる。
また、一方の前記コンタクト１４２の支点部３２から延設した方向にも前記ＦＰＣ４０又はＦＦＣと接触する接触部２２を設ける。このように前記ＦＰＣ４０又はＦＦＣの挿入方向に対して、直角方向両側に接触部２２を設けることで、前記ＦＰＣ４０又はＦＦＣを接触部２２、２２で挟持することになり、確実に前記ＦＰＣ４０又はＦＦＣと接触できるようになる。
さらにまた、もう一方の前記コンタクト１４２の支点部３２と接続部２４との間にも前記ＦＰＣ４０又はＦＦＣと接触する接触部２２を設ける。このように前記ＦＰＣ４０又はＦＦＣの挿入方向に対して、直角方向両側に接触部２２を設けることで、前記ＦＰＣ４０又はＦＦＣを接触部２２、２２で挟持することになり、確実に前記ＦＰＣ４０又はＦＦＣと接触できるようになる。
前記もう一方のコンタクト１４２の前記支点部３２から接続部２４と反対方向に延設された延設部４４を設け、前記スライダー１６１の押圧部３６が延設部４４と押受部２０との間で回動自在に前記スライダー１６１を前記ハウジング１２１に装着する。このように延設部４４を設け、この延設部４４と前記押受部２０との間でスライダー１６１を回動させることで、回動させた際により確実にもう一方のコンタクト１４２の接触部２２を前記ＦＰＣ４０又はＦＦＣに押圧することができる。
【０００９】
【作用】
前記ＦＰＣ４０又はＦＦＣが前記ハウジング１２、１２１の嵌合口１８内に挿入された後に、前記スライダー１６、１６１の押圧部３６が一方の前記コンタクト１４の接続部２４と押受部３６及びもう一方の前記コンタクト１４２の押受部２０と延設部４４との間で回動すると、前記押受部２０が押圧部３６によって押し上げられることで両方の前記コンタクト１４、１４２の支点部３２を支点にし、両方の前記コンタクト１４、１４２の弾性部３４が前記接触部２４側に傾くことによって、前記接触部２２が前記ＦＰＣ４０又はＦＦＣ側に押圧される。
【００１０】
【発明の実施の形態】
図１から図４に基づいて、本発明のコネクタの一実施例について説明する。
図１（Ａ）はスライダーが開いた状態の嵌合口側からみた本発明のコネクタの斜視図であり、（Ｂ）はスライダーが開いた状態の接続部側からみた本発明のコネクタの斜視図である。　図２（Ａ）はスライダーが開いた状態のあるコンタクト部分で切断した本発明のコネクタの斜視図であり、（Ｂ）はＦＰＣが挿入されスライダーが閉じた状態のあるコンタクト部分で切断した本発明のコネクタの斜視図である。図３はスライダーの斜視図である。図４（Ａ）は１つの接触部を持ったコンタクトの斜視図であり、（Ｂ）は２つの接触部を持った別のコンタクトの斜視図である。
本発明のコネクタは、主にハウジングとスライダーとコンタクトとを備えている。
【００１１】
図に基づいて本発明のコネクタの構成部品について説明する。
まず、本発明のポイントであるコンタクトについて説明する。このコンタクトは金属製であり、公知技術のプレス加工によって製作されている。前記コンタクトの材質としては、バネ性や導電性などが要求されるので、黄銅やベリリウム銅やリン青銅等を挙げることができる。
前記コンタクト１４は、図４（Ａ）のように略逆Ｈ字形状をしており、主にＦＰＣ４０又はＦＦＣと接触する接触部２２と基板に接続する接続部２４とハウジング１２に固定する固定部４２と前記接触部２２と前記接続部２４との間に設けられた弾性部３４及び支点部３２と前記接続部２４と対向する位置に前記弾性部３４から延設された押受部２０と支点部３２から延設した方向にも前記ＦＰＣ４０又はＦＦＣと接触するもう一つの接触部２２とを備えている。上方側の前記接触部２２（図２（Ａ）の図面の上側）と前記弾性部３４と前記支点部３２と前記接続部２４とは、略クランク形状に配置されている。前記接触部２２は、ＦＰＣ４０又はＦＦＣと接触し易いように凸部形状にしており、前記接続部２４は本実施例では図１のように表面実装タイプ（ＳＭＴ）にしているが、ディップタイプでも良い。即ち、２つの接触部２２、２２を設けて、前記ＦＰＣ４０又はＦＦＣを挟持するようにする。前記ＦＰＣ４０又はＦＦＣの挿入方向に対して、直角方向両側に接触部２２を設けることで、前記ＦＰＣ４０又はＦＦＣを２つの接触部２２、２２で挟持することになり、確実に前記ＦＰＣ４０又はＦＦＣと接触できるようになる。
【００１２】
前記支点部３２と前記弾性部３４と前記押受部２０とは、前記ＦＰＣ４０又はＦＦＣが挿入された際に、次のような作用を果たすための部分である。前記ＦＰＣ４０又はＦＦＣが前記ハウジング１２の嵌合口１８内に挿入された後に、前記スライダー１６の押圧部３６が前記コンタクト１４の接続部２４と押受部２０との間で回動すると、前記押受部２０が押圧部３６によって押し上げられることで前記コンタクト１４の支点部３２を支点にし、前記コンタクト１４の弾性部３４が前記接触部２２側に傾くことによって、前記接触部２２が前記ＦＰＣ４０又はＦＦＣ側に押圧される。前記支点部３２と前記弾性部３４と前記押受部２０の大きさや形状は、このような作用を果たすために、適宜設計されている。
また、前記コンタクト１４の押受部２０の先端に突出部２６を設け、スライダー１６の押圧部３６をコンタクト１４の押受部２０と接続部２４との間で回動させるときスライダー１６の回動に対する反発力が強い為に、スライダー１６の中央部が図１（Ｂ）の矢印「ロ」方向に膨れてしまうことを防ぐようにすることが望ましい。前記突出部２６の大きさは、このような役割を果たすことが出来れば如何なる大きさでもよく、スライダー１６の押圧部３６が引っ掛かる程度に適宜設計する。
【００１３】
図４（Ｂ）に基づいて、別のコンタクトについて説明する。ここでは、上述したコンタクト１４との相違部分についてのみ説明する。コンタクト１４１の支点部３２から延設した方向に設けたＦＰＣ４０又はＦＦＣとの接触部２２を削除したものであり、形状を略逆ｈ字形状にした。
【００１４】
次に、本発明のもう一つのポイントであるスライダーについて説明する。このスライダーは電気絶縁性のプラスチックであり、公知技術の射出成形によって製作され、この材質としては寸法安定性や加工性やコスト等を考慮して適宜選択するが、一般的にはポリブチレンテレフタレート（ＰＢＴ）やポリアミド（６６ＰＡ、４６ＰＡ）や液晶ポリマー（ＬＣＰ）やポリカーボネート（ＰＣ）やこれらの合成材料を挙げることができる。該スライダー１６は主にハウジング１２に回動可能に装着される軸２８部分と前記コンタクト１４の押受部２０を押圧する押圧部３６と前記コンタクト１４の突出部２６が係合する係止孔３０とを備えている。前記軸２８は、スライダー１６を回動するための支点であり、ハウジング１２の長手方向両側にスライダー１６が回動可能に適宜装着されている。また、長手方向両側には、前記コンタクト１４の押受部２０を押圧した際にスライダー１６が高さ（図面の上）方向に持ち上がらないようにするためにハウジング１２と係合するロック部が設けられている。ロック部の形状や大きさ等は、ハウジング１２に係合できれば如何なるものでもよく、上述の役割やコネクタの大きさや強度等を考慮して適宜設計する。
【００１５】
前記押圧部３６は、コンタクト１４の押受部２０に押し付ける部分であり、その形状としては細長形状にすることが望ましく、本実施例では楕円形状をしている。このように楕円形状にすることによって、図２（Ａ）のようにスライダー１６を矢印「イ」方向に回動させ、コンタクト１４の押受部２０と接続部２４との間で回転させることで、押圧部３６の大きさの変化によりコンタクト１４の押受部２０が持ち上げられ、ＦＰＣ４０又はＦＦＣをコンタクト１４の接触部２２側に押し付けている。押圧部３６の形状としては、コンタクト１４の押受部２０と接続部２４との間で回転でき、長軸と短軸といった大きさの違いによりコンタクト１４の押受部２０を押し上げられれば、如何なるものでもよい。
また、前記スライダー１６を回動した際に、スライダー１６の回動に対する反発力が強く、スライダー１６の中央部が図１（Ｂ）の矢印「ロ」方向に膨れてしまうことを防ぐようにする為に、前記コンタクト１４の突出部２６が係合する係止孔３０が別個独立に設けられている。前記係止孔３０を別個独立に設けることで、スライダー１６の強度アップや回動時の変形を防止している。
【００１６】
最後に、ハウジングについて説明する。このハウジングは電気絶縁性のプラスチックであり、公知技術の射出成形によって製作され、この材質としては寸法安定性や加工性やコスト等を考慮して適宜選択するが、一般的にはポリブチレンテレフタレート（ＰＢＴ）やポリアミド（６６ＰＡ、４６ＰＡ）や液晶ポリマー（ＬＣＰ）やポリカーボネート（ＰＣ）やこれらの合成材料を挙げることができる。
前記ハウジング１２には、所要数のコンタクト１４、１４１が装着される挿入溝３８が設けられており、圧入や引っ掛け（ランス）や溶着等によって固定されている。また、長手方向両側には、前記スライダー１６の軸２８が回動可能に装着される軸受部が設けられている。この軸受部の形状や大きさは、スライダー１６の軸２８が回動できるように装着されていれば如何なるものでもよく、この役割やハウジング１２の強度や大きさ等を考慮して適宜設計する。なお、長手方向両側には、前記スライダー１６のロック部に対応した位置に係止部が設けられている。
【００１７】
図５から図６に基づいて、本発明の別の実施例について説明する。主な構成部品は上述したものと同様で、ハウジングとコンタクトとスライダーとを備えている。本実施例の特徴は、２種類のコンタクト１４、１４２をハウジング１２１への挿入方向を変えて千鳥に配列している点にあり、挿入方向を変えて千鳥に配列することによってピッチの狭小化と低背位化に対応させたものである。前記ハウジング１２１と前記スライダー１６１は上述したものと同様であり、また、一方の前記コンタクト１４も上述した図４のものと同様であり、説明を省略する。図５は別のコネクタの斜視図であり、図６　（Ａ）はスライダーが開いた状態のもう一方のコンタクト部分で切断した本発明のコネクタの斜視図であり、（Ｂ）はＦＰＣが挿入されスライダーが閉じた状態のもう一方のコンタクト部分で切断した本発明のコネクタの斜視図である。
【００１８】
もう一方の前記コンタクト１４２も金属製であり、公知技術のプレス加工によって製作されている。材質は、一方のコンタクト１４と同様である。
もう一方の前記コンタクト１４２も一方の前記コンタクト１４と同様に略逆ｈ字形状と略Ｈ字形状の２つのタイプがあり、略逆ｈ字形状のものは、主にＦＰＣ４０又はＦＦＣと接触する接触部２２と基板に接続する接続部２４とハウジング１２１に固定する固定部４２と前記接触部２２と前記接続部２４との間に設けられた弾性部３４及び支点部３２と前記弾性部３４から延設された押受部２０を備えている。前記接触部２２と前記弾性部３４と前記支点部３２と前記接続部２４とは、略コ字形状に配置されている。略Ｈ字形状のものは、前記支点部３２からも接続部２４と反対方向に延設された延設部４４が設けられている。前記接触部２２は、ＦＰＣ４０又はＦＦＣと接触し易いように凸部形状にしており、前記接続部２４は本実施例では図５のように表面実装タイプ（ＳＭＴ）にしているが、ディップタイプでも良い。
【００１９】
前記支点部３２と前記弾性部３４と前記押受部２０とは、一方のコンタクト１４と同様に、前記ＦＰＣ４０又はＦＦＣが挿入された際に、前記スライダー１６１の押圧部３６が前記コンタクト１４２の押受部２０と前記ハウジング１２１との間若しくは押受部２０と延設部４４との間で回動すると、前記押受部２０が押圧部３６によって押し上げられることで前記コンタクト１４２の支点部３２を支点にし、前記コンタクト１４２の弾性部３４が前記接触部２２側に傾くことによって、前記接触部２２が前記ＦＰＣ４０又はＦＦＣ側に押圧される。前記支点部３２と前記弾性部３４と前記押受部２０の大きさや形状は、このような作用を果たすために、適宜設計されている。
また、前記コンタクト１４２の押受部２０の先端に突出部２６を設け、スライダー１６１の押圧部３６を回動させるときスライダー１６１の回動に対する反発力が強い為に、スライダー１６１の中央部が図６（Ｂ）の矢印「ハ」方向に膨れてしまうことを防ぐようにすることが望ましいが、ピッチの狭小化による前記スライダーの強度を考慮すると、２種類あるコンタクトの内、一方のコンタクト１４に設けておけば、十分である。前記突出部２６の大きさは、このような役割を果たすことが出来れば如何なる大きさでもよく、スライダー１６１の押圧部３６が引っ掛かる程度に適宜設計する。
【００２０】
【発明の効果】
以上の説明から明らかなように、本発明のコネクタによると、次のような優れた効果が得られる。
（１）スライダー１６、１６１をハウジング１２、１２１のコンタクト接続部２４側で回動させることで、コンタクト１４、１４１、１４２の接触部２２をＦＰＣ４０又はＦＦＣに接触させる構造にしているので、ハウジング１２、１２１の嵌合口１８にスライダー１６、１６１を挿入することがなく、スライダー１６、１６１の厚み分だけコネクタ１０、１０１の低背位化が可能になった。
（２）２種類のコンタクト１４、１４２を準備し、一方のコンタクト１４を接続部２４側から挿入し、もう一方のコンタクト１４２を嵌合口１８側から挿入し、前記スライダー１６１を接続部２４側で回動させることで、容易に狭小化と低背位化が可能になる。
（３）前記ＦＰＣ４０又はＦＦＣが前記ハウジング１２１の嵌合口１８内に挿入された後に、前記スライダー１６１の押圧部３６が一方の前記コンタクト１４の接続部２４と押受部２０との間で回動すると、前記押受部２０が押圧部３６によって押し上げられることで前記コンタクト１４、１４２の支点部３２を支点にし、前記コンタクト１４、１４２の弾性部３４が前記接触部２２側に傾くことによって、前記接触部２２が前記ＦＰＣ４０又はＦＦＣ側に押圧されるので、確実にコンタクト１４、１４２の接触部２２とＦＰＣ４０又はＦＦＣとを接続することができる。
（４）前記ＦＰＣ４０又はＦＦＣが前記ハウジング１２１の嵌合口１８内に挿入された後に、前記スライダー１６１の押圧部３６がもう一方の前記コンタクト１４２の押受部２０と前記ハウジング１２１との間若しくは押受部２０と延設部４４との間で回動すると、前記押受部２０が押圧部３６によって押し上げられることで前記コンタクト１４、１４２の支点部３２を支点にし、前記コンタクト１４、１４２の弾性部３４が前記接触部２２側に傾くことによって、前記接触部２２が前記ＦＰＣ４０又はＦＦＣ側に押圧されるので、確実にコンタクト１４、１４２の接触部２２とＦＰＣ４０又はＦＦＣとを接続することができる。
（５）一方の前記コンタクト１４若しくは両方１４、１４２の押受部２９の先端に突出部２６を設けているので、スライダー１６１の押圧部３６をコンタクト１４の押受部２０と接続部２４との間で回動させるときスライダー１６１の回動に対する反発力が強くても、スライダー１６１の中央部が矢印「ロ」方向に膨れてしまうことを防ぐことが出来る。
（６）前記スライダー１６、１６１の押圧部３６の形状を細長形状（長軸と短軸がある）にしているので、前記スライダー１６、１６１を回動した際に、確実に前記コンタクト１４、１４１、１４２の押受部２０を上方に押し上げ、接触部２２をＦＰＣ４０又はＦＦＣに容易に接触させることができる。
（７）前記スライダー１６、１６１には所要数の前記コンタクト１４、１４１の突出部２６と係合する係止孔３０を設け、該係止孔３０を別個独立にしているので、前記スライダー１６、１６１を強固で、確実に回動することができ、かつ、変形を生じない。
（８）一方の前記コンタクト１４の支点部３２から延設した方向にも前記ＦＰＣ４０又はＦＦＣと接触する接触部２２を設けると、前記ＦＰＣ４０又はＦＦＣの挿入方向に対して、直角方向両側に接触部２２を設けることになり、前記ＦＰＣ４０又はＦＦＣを接触部２２、２２で挟持することになるので、確実に前記ＦＰＣ４０又はＦＦＣと接触できるようになる。
（９）もう一方の前記コンタクト１４２の支点部３２と接続部２４との間のもＦＰＣ４０又はＦＦＣと接触する接触部２２を設けると、前記ＦＰＣ４０又はＦＦＣの挿入方向に対して、直角方向両側に接触部２２を設けることになり、前記ＦＰＣ４０又はＦＦＣを接触部２２、２２で挟持することになるので、確実に前記ＦＰＣ４０又はＦＦＣと接触できるようになる。
（１０）ＦＰＣ４０又はＦＦＣを挿入する側はハウジング１２、１２１の嵌合口１８で、コンタクト１４、１４１、１４２の接触部２２をＦＰＣ４０又はＦＦＣに押しつける動作はコンタクト１４、１４１、１４２の接続部２４側で行っているので、コネクタ１０、１０１が小型化しても作業性に影響がなく、容易に作業を行うことができる。

Since the FPC 40 or FFC is sandwiched between the contact portions 22, 22, the FPC 40 or FFC can be reliably brought into contact with the FPC 40 or FFC.
(9) If the contact portion 22 that contacts the FPC 40 or the FFC is also provided between the fulcrum portion 32 of the other contact 142 and the connection portion 24, the contact portion 22 is provided on both sides in a direction perpendicular to the insertion direction of the FPC 40 or the FFC. Since the contact portion 22 is provided and the FPC 40 or FFC is sandwiched between the contact portions 22, 22, it is possible to reliably contact the FPC 40 or FFC.
(10) The side into which the FPC 40 or FFC is inserted is the fitting port 18 of the housing 12, 121, and the operation of pressing the contact portion 22 of the contact 14, 141, 142 against the FPC 40 or FFC is performed on the connection portion 24 side of the contact 14, 141, 142.
