図9に示すように、アルミカバー503によって覆われたJ/B(ジャンクションボックス)505には、待受け側コネクタ507が設けられ、この待受け側コネクタ507が、アルミカバー503に設けられた取付開口509を通してアルミカバー503の外部に臨んでいる。そこで、シールドコネクタ501は、アルミカバー503の取付開口509から待受け側コネクタ507に嵌合される。
シールドコネクタ501は、待受け側コネクタ507に嵌合可能なハウジング(雌側ハウジング)511と、ハウジング511の外周面を覆う金属製のシールドシェル513と、シールドシェル513に設けられ弾性変形可能な押込片515と、ハウジング511に設けられ押込片515と弾性的に接触可能な係合突起517と、を備える。ボルト締結を行うことでシールドシェル513がアルミカバー側に接近させられ、これに伴って押込片515は、ハウジング511を待受け側コネクタ507に押し込むようにして係合突起517に接触する。
(1) 相手の雄端子が電気的に接続される端子接続部と、前記端子接続部に連設されて導体が電気的に接続される導体接続部とを有する雌端子と、前記雌端子を保持する電気絶縁性の雌側ハウジングと、を備えたコネクタであって、前記雌端子は、前記雄端子の嵌合方向と交差する方向に延出して平板状に形成された前記端子接続部に穿設された雄端子挿抜口と、前記雄端子挿抜口の開口周縁部に固定された固定側端から雄端子挿抜口中心に向って延びると共に、前記雄端子挿抜口の開口周縁部に沿って所定間隔に配置されることで、自由側端が前記雄端子挿抜口に挿入された前記雄端子に対して弾性的に接触する複数のばね接触片と、を備えるコネクタ。
図1及び図2に示すように、本発明の第1実施形態に係るコネクタ11は、雌端子13と、雌側ハウジング15と、を備える。雌端子13は、相手の雄端子17が電気的に接続される端子接続部19と、端子接続部19に連設されて導体21が電気的に接続される導体接続部23とを有する。端子接続部19と接続される雄端子17は、円柱端子の端子先端にテーパー25或いはR面をつけた形状で形成される。なお、本実施形態の雄端子17は円柱端子を例に説明するが、平タブ端子を用いることもできる。
雄側ハウジング53に保持された雄端子17は、雌側ハウジング15と雄側ハウジング53とがコネクタ結合されることで、雄端子収容部59の所定深さに配置される。この際、雄端子17は、先端部が雄端子収容部底面67との間にクリアランスを有して配置されることが好ましい。
本第1実施形態に係るコネクタ11によれば、雄端子17の嵌合方向と交差する方向に延出して平板状に形成された雌端子13の端子接続部19に、雄端子挿抜口37が穿設され、この雄端子挿抜口37には雄端子17が挿入される。即ち、雄端子17は、雌端子13の平板状の端子接続部19に対し垂直方向から挿入される。
また、雄端子17に対し弾性接触状態となったばね接触片41は、撓み可能空間に配置されていることで雌側ハウジング15に覆われる。そこで、他部材と接触することによる電気的接続の解除が防止され、電気的接続の信頼性が確保される。
図5及び図6に示すように、本発明の第2実施形態に係るコネクタ69は、ばね接触片73がL字状屈曲部75を有している(図7の(a)参照)。なお、本第2実施形態に係るコネクタ69において、上記第1実施形態に係るコネクタ11の構成部品と略同様の構成部品については、同符号を付して詳細な説明を省略する。
ばね接触片73の固定側端43は、端子接続部77の雄端子挿入側面47にスポット溶接等によって固定される。折り曲げ形成された自由側端45の先端部44は、端子接続部77の雄端子挿入側面47と反対側の面49上に配置される。雄端子挿抜口37に雄端子17が挿入されると、本第2実施形態における自由側端45の先端部44は、摺動面44bが反対側の面49上をスライドしながら半径方向外側に移動され、係止面44aがこの反対側の面49に突設された係止突起79に当接してスライドを規制される(図6参照)。
本第2実施形態のコネクタ69では、図8の(a)に示すように、ばね接触片73の固定側端43が雄端子挿入側面47に固定される。固定側端43が雄端子挿入側面47に固定されたばね接触片73は、雄端子挿抜口中心に向かって延出した後、屈曲されて雄端子挿入側面47と反対側の面49に沿って、自由側端45が雄端子挿抜口37の半径方向外側に延出する。即ち、ばね接触片73は、雄端子挿抜口中心に近接するL字状屈曲部75を有して長尺に形成されている。
更に、本第2実施形態のばね接触片73は、自由側端45の先端部44に形成された摺動面44bが、反対側の面49上をスライドしながら半径方向外側に移動されるので、片持ち梁状態でありながらばね定数を増大させることなく雄端子17との接触荷重を大きくすることができ、コネクタ挿抜力を低減することができる。
そして、半径方向外側に所定以上移動した自由側端45の先端部44は、係止面44aが雄端子挿入側と反対側における端子接続部77の係止突起79に当接することによってそのスライドが規制される。そこで、ばね接触片73は、完全に両持ち梁状態となって雄端子17との接触がより確実になる。また、ばね接触片73は、両持ち梁状のばね構造として配置されることで、固定側端43から自由側端45までの長尺の全長に亘って弾性変形し、弾性限度に対し余裕を持った範囲での弾性変形が可能となる。これにより、ばね接触片73がへたりにくくなって、長期にわたり高い電気接続信頼性が得られる。なお、半径方向外側に所定以上移動した自由側端45の先端部44は、係止面44aが端子接続部77の係止突起79に当接することによってそのスライドが規制されるが、本発明はこれに限定されるものではなく、雄端子挿入側と反対側における雌側ハウジングの壁部等によってそのスライドが規制される構成とすることもできる。
