Description

【０００１】
【発明の属する技術分野】
本発明は、ケーブルを保護する管を備えたコネクタと相手側コネクタとを接続する機構に関する。
【０００２】
【従来の技術】
２つの従来の保護管を備えたコネクタの接続機構について説明する。
【０００３】
まず、第１の従来の保護管を備えたコネクタの接続機構について図３を参照して説明する。
【０００４】
プラグコネクタ３１内には、複数本のケーブル（図示せず）が挿通し、各ケーブルはフレキシブル円管３２により被覆されている。レセプタクルコネクタ４１は、パネル５１に固定され、プラグコネクタ３１とレセプタクルコネクタ４１とは、嵌合している。
【０００５】
次に、第２の従来の保護管を備えたコネクタの接続機構について図４を参照して説明する。
【０００６】
コネクタ６１は、おす側接続機構部６１Ａとめす側接続機構部６１Ｂとから構成される。おす側接続機構部６１Ａ内には、複数本のケーブル６２が挿通し、各ケーブル６２はフレキシブル円管６３により被覆されている。めす側接続機構部６１Ｂは、パネル７１にはめ込みにより固定され、おす側接続機構部６１Ａのおすねじ６１Ｃをめす側接続機構部６１Ｂのめすねじ６１Ｄにねじ込むと、プラグコネクタ６１は図４（ａ）の状態に至る。
【０００７】
おす側接続機構部６１Ａをめす側接続機構部６１Ｂから外しても、各ケーブル６２は相手側コネクタの端子（図示せず）と接続しているため、コネクタ６１と相手側コネクタとの電気的接続は解除されない。
【０００８】
【発明が解決しようとする課題】
第１の従来のコネクタの接続機構では、プラグコネクタ３１とレセプタクルコネクタ４１とが単純に接続され、しかも、レセプタクルコネクタ４１がパネル５１の表面に固定されるので、中心軸方向の長さが長くなるという欠点が生じる。
【０００９】
第２の従来のコネクタの接続機構では、おす側接続機構部６１Ａがめす側接続機構部６１Ｂにねじ込まれ、しかも、めす側接続機構部６１Ｂがパネル７１にはめ込まれているので、中心軸方向の長さが第１の従来のコネクタの接続機構よりも短くなる。しかし、おす側接続機構部６１Ａをめす側接続機構部６１Ｂから外しても、コネクタ６１と相手側コネクタとの電気的接続は解除されないという欠点が生じる。
【００１０】
そこで、本発明は、前記両従来のコネクタの接続機構の欠点を改良し、コネクタの中心軸方向の長さが短く、しかも、コネクタを相手側コネクタから外すと、電気的接続が同時に解除される、保護管を備えたコネクタの接続機構を提供しようとするものである。
【００１１】
【課題を解決するための手段】
本発明は、前記課題を解決するため、次の手段を採用する。
【００１２】
１．ケーブルを保護する保護管を備えたコネクタにおいて、前記コネクタは、コンタクトと、前記コンタクトを保護するハウジングと、前記保護管とを有し、前記保護管は、太径部と細径部とを有し、相手側コネクタは、コンタクトと、該コンタクトを保持するハウジングとを有し、前記相手側コネクタのハウジングは、前記コネクタのハウジングが挿入される嵌合部と、前記保護管をロックするロック片とを有し、前記相手側コネクタの嵌合部には、環状段部が設けられ、前記ロック片は、一対であって、前記嵌合部に対して対称的に配設され、それぞればねによって前記保護管をロックする方向に付勢され、かつ、前記相手側コネクタのハウジングにスライド可能に保持され、前記保護管が前記相手側コネクタのハウジングに挿入されると、前記太径部と前記環状段部とが係合し、前記細径部と前記各ロック片の先端とが係合し、前記保護管が前記相手側コネクタのハウジングに着脱可能にロックされる保護管を備えたコネクタの接続機構。
【００１３】
２．前記嵌合部にはパッキングが挿入され、前記相手側コネクタのハウジングと前記保護管の最先端部との間のシーリングが行われる前記１記載の保護管を備えたコネクタの接続機構。
【００１５】
【発明の実施の形態】
本発明の一実施の形態例の保護管を備えたコネクタの接続機構について図１を参照して説明する。
【００１６】
まず、プラグコネクタ１について説明する。ハウジング２には、複数本の端子３Ａ，３Ｂが保持される。図１（ａ）において、便宜上、上側に半田付タイプの場合の端子３Ａが、下側に圧着タイプの場合の端子３Ｂが、それぞれ示されている。複数本のケーブル４は、コルゲート形状のフレキシブル円管５により被覆される。各端子３Ａ，３Ｂと各ケーブル４とを接続した後、フレキシブル円管５を、図１（ｂ）に示される矢印方向へハウジング２にはめると、図１（ｃ）の状態に至る。
【００１７】
次に、レセプタクルコネクタ１１について説明する。図１（ｂ）〜図２（ｂ）に示されるように、ハウジング１２の中央には、円形嵌合部１２Ａが形成され、円形嵌合部１２Ａに複数本の端子１３が保持される。また、円形嵌合部１２Ａの入口側には、環状段部１２Ｂが形成される。ハウジング１２の入口側に形成された上下一対の溝１２Ｃには、それぞれロック片１４がスライド可能に挿入されている。プラグコネクタ１がレセプタクルコネクタ１１に嵌合していないときには、図２（ａ）に示されるように、上側のロック片１４はばね（図示せず）により下方に付勢されて実線の状態に位置し、また、下側のロック片１４は他のばね（図示せず）により上方に付勢されて実線の状態に位置する。環状段部１２Ｂには、リング状パッキング１５が挿入される。なお、レセプタクルコネクタ１１は、図１（ｂ）に示されるように、パネル２１にはめ込まれる。
【００１８】
プラグコネクタ１とレセプタクルコネクタ１１との嵌合について説明する。図１（ｃ）に示されるように、プラグコネクタ１の先端をレセプタクルコネクタ１１の円形嵌合部１２Ａ内に矢印方向に挿入する。すると、フレキシブル円管５の最先端の太径部５Ａが、上側のロック片１４をその先端１４Ａを押すことにより２点鎖線の位置まで上方にスライドさせ、また、下側のロック片１４をその先端１４Ａを押すことにより２点鎖線の位置まで下方にスライドさせる。続いて、フレキシブル円管５の最先端の太径部５Ａに隣接する細径部５Ｂが各ロック片１４の先端１４Ａの位置まで至ると、各ロック片１４は２点鎖線の位置から実線の位置まで戻るので、プラグコネクタ１はレセプタクルコネクタ１１にロックされる。このとき、プラグコネクタ１の各端子３Ａ，３Ｂがレセプタクルコネクタ１１の各端子１３に接触し、また、図１（ｄ）に示されるように、リング状パッキング１５は環状段部１２Ｂとフレキシブル円管５の最先端の太径部５Ａとの間で挟圧され、両コネクタ１，１１は嵌合を完了して図２（ｃ）の状態に至る。
【００１９】
プラグコネクタ１とレセプタクルコネクタ１１との離脱について説明する。まず、図２（ｃ）に示される両コネクタ１，１１の嵌合状態において、各ロック片１４の先端１４Ａを図２（ａ）に示される実線の位置から２点鎖線の位置までスライドさせると、両コネクタ１，１１のロックが解除される。次に、フレキシブル円管５を円形嵌合部１２Ａから引き抜くと、両コネクタ１，１１は図１（ｃ）に示される離脱状態に至る。
【００２０】
【発明の効果】
以上の説明から明らかなように、本発明によれば、次の効果を奏することができる。
【００２１】
１．結線した端子をハウジングに組込み、又は、ハウジングに組込まれている端子に結線し、保護管を相手側コネクタにロックするだけで、コネクタと相手側コネクタとの嵌合が完了する。したがって、作業性が向上し、部品点数が減少し、また、コストが低減する。
【００２２】
２．コネクタのハウジング及び保護管のロック部が、相手側コネクタのハウジングに収容されるため、接続機構がコンパクトに構成される。
【００２３】
３．コネクタを相手側コネクタから外すと、電気的接続が同時に解除されるので、便利である。
【図面の簡単な説明】
