ここで、端子がインナハウジングに保持され、付勢部材がアウタハウジングとインナハウジングとの間に配置されるため、端子と付勢部材とを互いに影響し合わない構造にすることができる。そして、インナハウジングに保持される端子の個数も付勢部材と関わりなく自由に設定することができる。したがって、端子を含むコネクタの構造を簡略化することができ、コストの低減を図ることができる。
上記構成によれば、インナハウジングがアウタハウジングの円周面に沿って周方向に回転することができるため、インナハウジングがアウタハウジングに対して径方向等に移動する場合に比べ、コネクタが大型化するのを抑制することができる。
上記構成によれば、複数の端子保持部にそれぞれ端子が保持される場合であっても、複数の付勢部材を設ける必要がなく、好ましくは、一つの付勢部材で賄うことができる。その結果、部品点数を削減でき、さらなるコストの低減を図ることができる。
上記構成によれば、係合受部の構造が複雑化するのを抑えることができる。
上記構成によれば、インナハウジングが進出位置にあるときに、進退方向に延びる前方係合受部が係合部を受け入れるため、端子がワイピング動作を開始するまでの間、付勢部材が付勢力を蓄えて、端子がワイピングするのに適した接圧に到達することができる。
上記構成によれば、インナハウジングが退入位置にあるときに、進退方向に延びる後方係合受部が係合部を受け入れるため、端子がワイピング動作を完了し、コネクタを組み込んだモジュール等が相手側のモジュールにロックされる場合に、ロック機構の公差等に起因する可動範囲内で、インナハウジングを移動させることができる。
本開示の実施形態の具体例を、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。
アウタハウジング20は合成樹脂製である。図1に示すように、アウタハウジング20は、キャップ状をなし、円板状の背面部21と、背面部21の外周から前方に突出する円筒状の外周部22と、を有している。背面部21の前面の中心部には、円環状のアウタ側ばね装着部23が突出して設けられている。図3に示すように、巻きばね50の後述するアウタ側装着部51は、アウタ側ばね装着部23の凹み内に嵌合して支持される。
インナハウジング60は合成樹脂製である。図2に示すように、インナハウジング60は、円柱状をなし、アウタハウジング20内に嵌合される。インナハウジング60の外周面は、アウタハウジング20の円周面25に沿って周方向に摺動可能とされている。インナハウジング60は、前面に、径方向に沿った端面61を有している。インナハウジング60の径方向中心には、前後方向に貫通する軸心孔62が設けられている。インナハウジング60には、周方向に間隔を置いて複数の端子保持部63が設けられている。各端子保持部63は、インナハウジング60において、周方向に3箇所等間隔を置いて配置される。図3に示すように、端子保持部63は、前後方向に延びる貫通孔であって、延び方向の途中に、前方に突出する弾性変形可能なランス64を有している。インナハウジング60がアウタハウジング20に組み付けられた状態において、端子保持部63と電線挿通孔24とは前後方向に同軸上に配置される。
巻きばね50としては、金属製の圧縮コイルスプリングが例示される。図3に示すように、巻きばね50は、後端部にアウタハウジング20のアウタ側ばね装着部23の凹み内に装着されるアウタ側装着部51を有し、前端部にインナハウジング60のインナ側ばね装着部66内に装着されるインナ側装着部52を有している。アウタ側装着部51の外周面は、アウタ側ばね装着部23の凹みの内周面に沿って配置される。インナ側装着部52の内周面および外周面は、それぞれインナ側ばね装着部66の内周面および外周面に沿って配置される。インナハウジング60が進出位置にあるときに、巻きばね50はアウタハウジング20とインナハウジング60との間に自然状態または少し圧縮された状態で配置される。図2に示すように、インナハウジング60の前部は、アウタハウジング20から前方に突出して配置される。これに対し、インナハウジング60が退入位置にあるときに、巻きばね50はアウタハウジング20とインナハウジング60との間に強く圧縮された状態で配置される。インナハウジング60は、進出位置にあるときよりもアウタハウジング20から小さく突出し、またはアウタハウジング20内に全体が引っ込むように配置される。
端子80は、導電性に優れた金属製であって、前後方向に細長く延びる形状になっている。図3に示すように、端子80は、前方に突出するタブ状またはピン状の接続部81と、接続部81の後方に位置して電線200の端部に圧着されるバレル状の圧着部82と、を有している。端子80は、端子保持部63内に挿入され、接続部81の後端にランス64を係止させることで、端子保持部63内に抜け止めされる。端子80がランス64に係止された状態で、接続部81の先端がインナハウジング60の端面61から前方に突出して配置される。圧着部82に接続された電線200は、インナハウジング60の後面から後方に引き出される。また、インナハウジング60がアウタハウジング20に組み付けられた状態において、電線200は、アウタハウジング20の電線挿通孔24から後方に引き出される。
ストッパ90は合成樹脂製であって、図2に示すように、アウタハウジング20のストッパ受部29に嵌合可能な形状になっている。ストッパ90は、本体部分から周方向の両側に張り出す形状の拡幅部91を有している。ストッパ90の拡幅部91は、ストッパ受部29の段部31に圧入して固定される。
まず、アウタハウジング20の電線挿通孔24に電線200の端部に接続された電線200を通し、その状態からインナハウジング60の端子保持部63に電線200の端部に接続された端子80を挿入して保持させる。次いで、アウタハウジング20とインナハウジング60との間に巻きばね50を介在させつつアウタハウジング20の外周部22の内側に前方からインナハウジング60を嵌め込む。このとき、アウタハウジング20の前方係合受部28にインナハウジング60の係合部67を挿入する。続いで、ストッパ受部29にストッパ90を圧入する。図3および図4に示すように、係合部67がストッパ90に後方から当接することで、インナハウジング60の、アウタハウジング20から前方への抜け出しが規制される。インナハウジング60は、巻きばね50によって付勢されることで、係合部67がストッパ90に当接する状態を維持することができる。このようにして、インナハウジング60は、アウタハウジング20に対して前部側を突出させた進出位置に留め置かれる。
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。
上記実施形態の場合、凸状の係合部がインナハウジングに形成され、凹状の係合受部がアウタハウジングに形成されていた。しかし、他の実施形態によれば、凸状の係合部がアウタハウジングに形成され、凹状の係合受部がインナハウジングに形成されていても良い。
上記実施形態の場合、インナハウジングは、アウタハウジングに対して前後方向および径方向と直交する周方向に移動可能となっていた。しかし、他の実施形態によれば、インナハウジングは、アウタハウジングに対して前後方向と交差する方向に移動可能となっていれば良く、例えば、径方向に移動可能となっていても良い。
上記実施形態の場合、端子の接続相手は、回路基板の相手接続部であった。しかし、他の実施形態によれば、端子の接続相手は、回路基板に限らず、例えば、接続端子やバスバーであっても良い。
上記実施形態の場合、インナハウジングとアウタハウジングとの間に巻きばねが配置されていた。しかし、他の実施形態によれば、インナハウジングとアウタハウジングとの間に付勢部材が配置されていれば良く、例えば、板ばねやクッションが配置されていても良い。
上記実施形態の場合、一つのコネクタに一つの付勢部材が設けられていた。しかし、他の実施形態によれば、一つのコネクタに複数の付勢部材が設けられていても良い。
