【００１０】
【発明の実施の形態】
以下、図面に基づいて本発明の実施の形態を詳細に説明する。
図１は、本発明にかかる電気コネクタ１１の一実施形態の構成を示す簡略化した分解斜視図である。図中、１２は内側ハウジング、１３は雄接続端子、１４はシールド、１５は外側ハウジング、１６はパッキング、３１は金属接触部材、４１は楔、５１はスペーサである。
図２（ａ）、（ｂ）、（ｃ）はそれぞれ、上記電気コネクタ１１を壁体２１に取り付け、シールド１４とアース部材である金属製の壁体２１を電気的に接続した接続構造の平面図、正面図、側面図である。また、図３（ａ）、（ｂ）はそれぞれ、図２（ｂ）のＡ−Ａ断面に相当する電気コネクタ１１の断面図、および図２（ｃ）のＢ−Ｂ断面に相当する電気コネクタ１１の断面図である。
【００１１】
本実施形態の電気コネクタ１１は、図２に示すように、筐体の金属製の壁体２１を貫通して取り付けられ、シールド１４は金属接触部材３１を介して壁体２１に電気的に接続する。
ここで、上記電気コネクタ１１について先ず説明し、次いで前記電気コネクタ１１のシールド１４と壁体２１の接続構造について説明する。
【００１２】
電気コネクタ１１は、図３（ａ）、（ｂ）に示すように、合成樹脂からなる内側ハウジング１２に合成樹脂からなる外側ハウジング１５が外嵌された構造をしている。
【００１３】
内側ハウジング１２は、図４（ａ）、（ｂ）に示すように、筐体内のバスバをボルトとナットで接続するための穴１３ａが設けられた２本の雄端子１３が挿入されている。また、内側ハウジング１２には、後述の楔を挿入するための２個の貫通穴１２ａが設けられている。さらに、内側ハウジング１２の外周面には、金属薄板からなり略四角形に曲げられたシールド１４が囲繞するように取り付けられている。なお、シールド１４の壁体２１を貫通する側の端部表面には、雄端子１３に直交する方向（取り付ける壁体２１面に平行な方向）に滑り止めとなるノッチ１４ａが設けられている。
【００１４】
外側ハウジング１５は、図５（ａ）、（ｂ）に示すように、壁体２１への取り付け側の略四角形をなす周端面に壁体２１を貫通する方向に張出した張出部１５ａが設けられており、また、リング状の防水用パッキングを嵌め込む溝１５ｂが設けられている。
【００１５】
内側ハウジング１２と外側ハウジング１５が嵌合した状態では、図３（ａ）、（ｂ）に示すように、内側ハウジング１２と外側ハウジング１５は内側ハウジング１２の位置決め用の凸部１２ｂで相対的に位置決めされて、内側ハウジング１２は外側ハウジング１５の壁体２１への取り付け側の端部から突出するように位置しており、シールド１４の端部および貫通穴１２ａは外側ハウジング１５の外側に位置している。また、外側ハウジング１５の溝１５ｂにはパッキング１６が嵌め込まれている。
【００１６】
金属接触部材３１は、図６に示すように、前記内側ハウジング１２に外嵌するように形成された環状の金属板部材であって、略四角形をした内周縁には内側方向に張り出した１０個の爪状の張出部３１ａが対向するように設けられている。
【００１７】
本実施形態の電気コネクタ１１のシールド１４とアース部材である壁体２１の接続構造は、以下のように形成する。即ち、
１）図２（ａ）、（ｂ）に示すように、電気コネクタ１１の内側ハウジング１２の外側ハウジング１５より突出した部分を壁体２１の左側（筐体の外側）から壁体２１の貫通穴（図示されず）に貫通させ、外側ハウジング１５の周端部を壁体２１面に当接させて、張出部１５ａを壁体２１の右側（筐体の内側）に突出させる。
【００１８】
２）次いで、金属接触部材３１を壁体２１の右側から内側ハウジング１２に外嵌して、壁体２１面に面接触するまで押し込み、図２（ｃ）に示すように、外側ハウジング１５の張出部１５ａの外側に嵌め込んで保持する。この状態で、金属接触部材３１の１０個の張出部３１ａは自らのバネ性で、シールド１４に圧接する。
なお、金属接触部材３１の対向する張出部３１ａの間隔Ｌ１ 、Ｌ２ （図６参照）はそれぞれ、シールド１４が形成する略四角形の対向する二辺の間隔Ｄ１ 、Ｄ２ （図４（ｂ）参照）よりも若干小さくなっている。したがって、金属接触部材３１を内側ハウジング１２に外嵌して押し込む際には、張出部３１ａは撓みながらシールド１４のノッチ１４ａを引っ掻くように擦り、シールド１４に圧接する。
【００１９】
３）次いで、図７に示したコ字状の楔４１と図８に示したコ字状のスペーサ５１を用いて金属接触部材３１を壁体２１に押圧する。
即ち、先ずスペーサ５１の脚部５１ａを内側ハウジング１２の貫通穴１２ａに差し込み、次いで楔４１の脚部４１ａを金属接触部材３１とスペーサ５１の間に押し込んで貫通穴１２ａに差し込む。この状態で、図２（ｂ）に示すように、楔４１は頭部４１ｂと脚部４１ａで金属接触部材３１を壁体２１に確実に押圧するとともに、壁体２１を外側ハウジング１５の周端部に押圧し、電気コネクタ１１と金属接触部材３１は壁体２１を挟むように取り付けられる。
【００２０】
上述のように取り付けられた金属接触部材３１は、壁体２１に押圧されて電気的に接続するとともに、張出部３１ａでシールド１４のノッチ１４ａに滑ることなく圧接して、シールド１４に確実に電気的に接続し、壁体２１とシールド１４は金属接触部材３１を介して電気的に接続している。また、外側ハウジング１５の周端部は、図３（ａ）、（ｂ）に示すように、溝１５ｂに嵌め込まれたパッキング１６を介して壁体２１の左面（筐体の外側）に押圧されているので、電気コネクタ１１を防水可能に壁体２１に取り付けることができる。
【００２１】
本実施形態の電気コネクタ１１が従来例と異なる特徴的なことは、シールド１４が、壁体２１を貫通した状態で配置され、壁体２１を貫通したシールド１４と壁体２１には金属接触部材３１が圧接するように取り付けられることである。したがって、電気コネクタ１１のシールド１４とアース部材である壁体２１を金属接触部材３１を介して電気的に信頼性よく接続することができる。
【００２２】
なお、上記実施形態は本発明を具体化した一例であって、本願発明の技術的範囲を限定するものではない。例えば、金属接触部材を壁体へ押圧して固定する手段は、スペーサと楔を用いることなく、壁体の厚さが厚い場合には楔だけでもよい。
【００２３】
【発明の効果】
以上説明したように、請求項１記載の発明によれば、金属接触部材がアース部材を貫通した電気コネクタのシールドとアース部材に圧接して確実に電気的に接続するので、電気コネクタのシールドをアース部材に電気的に信頼性よく接続し、電気コネクタ周辺からのノイズの発生を抑制することができるという優れた効果がある。
また、請求項２記載の発明によれば、環状の金属接触部材が前記内側ハウジングの貫通した先端側から前記内側ハウジングに外嵌されているため、金属接触部材は電気コネクタのシールドとアース部材により確実に電気的に接続することができるという優れた効果がある。
さらに、請求項３記載の発明によれば、前記外側ハウジングと前記アース部材の間に防水用パッキングを介在させて、前記金属接触部材と前記外側ハウジングとで前記アース部材を挟むため、電気コネクタを防水可能にアース部材に取り付けることができるという優れた効果がある。

Here, the electrical connector 11 will be described first, and then the connection structure between the shield 14 of the electrical connector 11 and the wall 21 will be described.
[0012]
As shown in FIGS. 3A and 3B, the electrical connector 11 has a structure in which an outer housing 15 made of synthetic resin is externally fitted to an inner housing 12 made of synthetic resin.
[0013]
As shown in FIGS. 4A and 4B, the inner housing 12 has two male terminals 13 provided with holes 13a for connecting a bus bar in the housing with bolts and nuts. Further, the inner housing 12 is provided with two through holes 12a for inserting wedges described later. Further, a shield 14 made of a thin metal plate and bent into a substantially rectangular shape is attached to the outer peripheral surface of the inner housing 12 so as to surround the same. A notch 14a is provided on the end surface of the shield 14 on the side penetrating the wall 21 in a direction perpendicular to the male terminal 13 (a direction parallel to the surface of the wall 21).
