本開示の具体例を、以下に図面を参照しつつ説明する。なお、本発明はこれらの例示に限定されるものではなく、請求の範囲によって示され、請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。
図1には、実施形態1のコネクタ10が開示されている。コネクタ10は、図5に示すように、雄端子金具20と、雄側ハウジング30と、雌端子金具50と、雌側ハウジング60と、リテーナ90と、を備えている。
雄端子金具20は、導電性を有している。雄端子金具20は、例えば金属製である。雄端子金具20は、図5に示すように、基部21と、タブ22と、を有している。タブ22は、基部21よりも後側に配置され、後方に向けて突出している。つまり、基部21及びタブ22は、前後方向に延びている。雄端子金具20は、幅方向に間隔をあけて複数(本実施形態では4本)設けられている。
雄側ハウジング30は、複数の雄端子金具20を収容する。雄側ハウジング30は、絶縁性を有している。雄側ハウジング30は、例えば合成樹脂製である。雄側ハウジング30は、図2及び図5に示すように、フード部31を有している。フード部31は、後方に開放された筒状、より具体的には角筒状をなしている。フード部31は、壁部32と、壁部32の外周から後方に向けて筒状(より具体的には角筒状)に突出した筒部33と、を有している。
雌端子金具50は、導電性を有している。雌端子金具50は、例えば金属製である。雌端子金具50は、例えば金属板を曲げ加工して形成される。雌端子金具50は、図5に示すように、本体部51と、電線接続部52と、を有している。本体部51は、筒状をなしており、内部にタブ22が挿入される。これにより、雌端子金具50が雄端子金具20と電気的に接続される。電線接続部52には、圧着などによって電線91の導体92が電気的に接続される。雌端子金具50は、幅方向に間隔をあけて複数(本実施形態では4本)設けられている。
雌側ハウジング60は、複数の雌端子金具50を収容する。雌側ハウジング60は、絶縁性を有している。雌側ハウジング60は、例えば合成樹脂製である。雌側ハウジング60は、図5に示すように、雌側ハウジング60が雄側ハウジング30のフード部31に嵌合した嵌合状態において、フード部31の奥面40と対向する対向面60Aを有している。対向面60Aは、雌側ハウジング60の前面に形成されている。対向面60Aは、図4に示すように、第1対向面61と、第2対向面62と、第3対向面63と、第4対向面64と、第5対向面65と、を有している。第1対向面61、第2対向面62、第3対向面63、第4対向面64、及び第5対向面65は、平坦な面であり、前方を向いている。第2対向面62、第3対向面63、第4対向面64、及び第5対向面65は、段差なく連続した面である。
リテーナ90は、雌側ハウジング60に係止され、キャビティ69内に配置された雌端子金具50の後方への抜けを防止する。
コネクタ10は、嵌合状態において、雄側ハウジング30と雌側ハウジング60との間の隙間に異物が侵入するおそれがある。例えば、コネクタ10が油中環境下に置かれる場合、ロックアーム76の上面にモータの金属屑などの異物とともに油が飛散する。異物は、図6に示す矢印のように、油に流されてロックアーム76の上面を移動し、雄側ハウジング30と雌側ハウジング60との間の隙間に侵入するおそれがある。そして、異物が侵入すると、雄端子金具20が、幅方向に間隔をあけて配置される別の雄端子金具20などに対し、異物を介して短絡するおそれがある。そこで、異物が雄端子金具20に接触しにくくなるようにすることが求められる。
今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えるべきである。
(1)第2対向面は、第1対向面よりも前側に配置される構成であってもよい。第2奥面は、第1奥面よりも前側に配置される構成であってもよい。雌側段差面は、下方を向いていてもよい。雄側段差面は、上方を向いていてもよい。
(2)第3奥面は、第1奥面と面一であってもよい。
(3)排出孔は、雌側段差面に開口する構成であってもよい。排出孔は、第2対向面と雌側段差面の両方に開口する構成であってもよい。
(4)排出孔の内周面は、傾斜面を有しない構成であってもよい。
(5)フード部の内周面は、排出溝を有しない構成であってもよい。
(6)第2雄側段差面は、スロープ部を有しない構成であってもよい。
(7)雄側ハウジングは、凸部を有しない構成であってもよい。
