Description

【０００１】
【発明の属する技術分野】
本発明は、ホースやパイプなどを配管のために連結するコネクタに関し、より詳しくは雄部材と雌部材との連結状態を確認することのできるコネクタに関する。
【０００２】
【従来の技術】
ホースなどを連結するコネクタとして、図１８及び図１９に示すものが知られている。このコネクタは、先端から所定の距離隔てた位置に遠心方向に突出するリング状突部８０ａが設けられたパイプ状の雄部材８０と、雄部材８０が挿入される挿入開口端８１ａをもつ略円筒状のハウジング８１を有する雌部材８２と、ハウジング８１の挿入開口端８１ａ側の端部に挿入保持され、ハウジング８１内に挿入された雄部材８０を雌部材８２に連結させるための係止部材８３と、ハウジング８１の外周面に軸直角方向から外装保持され、雌部材８２に雄部材８０が結合されたことを確認するための確認部材８４とから構成されている。
【０００３】
上記ハウジング８１の挿入開口端８１ａ側の端部には半径方向に貫通し互いに対向するように周方向に配設された一対の窓部８１ｂが設けられ、上記係止部材８３は半径方向に弾性変形可能で該窓部８１ｂと対応する位置に配設された一対の爪部８３ａを有している。また、上記確認部材８４は、図１９に示すように、弾性変形により拡径可能な略Ｃ字形状をなし、上記ハウジング８１の上記窓部８１ｂの端部に連続的に設けられた切欠溝８１ｃ内に挿入されて、ハウジング８１の外周面に軸直角方向から外装保持されている。そして、この確認部材８４は、上記雄部材８０が上記雌部材８２に結合される前の状態で上記窓部８１ｂの端縁と係止して上記ハウジング８１から確認部材８４が軸直角方向に外れることを規制する一対の係止凹部８４ａ、上記雄部材８０の挿入時に上記リング状突部８０ａの外周面が当接する一対の先端当接部８４ｂを有している。
【０００４】
このコネクタでは、雄部材８０を雌部材８２に結合させる前の状態において、確認部材８４がハウジング８１の外周面に軸直角方向から外装保持され、確認部材８４の係止凹部８４ａがハウジング８１の窓部８１ｂの端縁に係止されるとともに、確認部材８４の先端当接部８４ｂが窓部８１ｂ内で上記係止部材８３の爪部８３ａよりも軸方向奥側の位置に挿入されている。この状態で、雄部材８０を雌部材８２のハウジング８１内に挿入すると、雄部材８０のリング状突部８０ａは、係止部材８３の爪部８３ａをその弾性に抗して半径方向外方に押し拡げ、爪部８３ａを通過する。これにより、爪部８３ａの先端とリング状突部８０ａとが係止して、雄部材８０と雌部材８２とは結合状態とされる。この結合状態（図１８及び図１９の状態）では、雄部材８０のリング状突部８０ａは、確認部材８４の先端当接部８４ｂを半径方向外方に押し拡げる。すると、確認部材８４の係止凹部８４ａが窓部８１ｂの端縁から外れ、確認部材８４は軸直角方向（図１９の矢印方向）にその弾性により飛び出て外れる。これにより、雄部材８０が雌部材８２に結合されたことを確認することができる。
【０００５】
【発明が解決しようとする課題】
上述のように従来のコネクタは、雄部材８０が雌部材８２に結合された時に、確認部材８４がその弾性復帰力によりハウジング８１から軸直角方向に外れることで、雄部材８０が雌部材８２に結合されたことを確認するものである。
なお、上記従来のコネクタでは、確認部材８４をハウジング８１から軸直角方向に外れ易くするために、ハウジング８１に切欠溝８１ｃを設けて確認部材８４が跨るハウジング８１の側壁の周方向幅を狭くしたり、あるいは確認部材８４の先端当接部８４ｂの内面側に中間部材を別途配設し、この中間部材を介してリング状突部８０ａにより確認部材８４の先端当接部８４ｂを半径方向外方に押し拡げたりする工夫がなされている。
【０００６】
しかし、雄部材８０が雌部材８２に結合されたと同時に、確認部材８４がその弾性復帰力によりハウジング８１から外れて飛び出てしまうと、結合後にハウジング８１から外れ落ちた確認部材８４を拾い集める必要があり、コネクタを適用する箇所によってはそれが極めて困難となる場合がある。また、確認部材８４が外れ落ちては困るような箇所には、上記従来のコネクタを適用することができない。
【０００７】
本発明は上記実情に鑑みてなされたものであり、雄部材と雌部材との結合後に、確認部材がその弾性により飛び出てしまうことのないコネクタを提供することを解決すべき技術課題とするものである。
【０００８】
【課題を解決するための手段】
（１）請求項１記載のコネクタは、先端から所定の距離隔てた位置に遠心方向に突出するリング状突部が設けられた挿入端部をもつ筒状の雄部材と、
上記挿入端部が挿入される挿入開口端、及び半径方向に貫通し互いに対向するように周方向に配設された一対の窓部を有する略円筒状のハウジングを軸方向一端側に備えた雌部材と、
上記ハウジング内に挿入保持され、半径方向に弾性変形可能で上記窓部と対応する位置に配設された一対の爪部を有し、各該爪部は、上記挿入開口端から軸方向奥方に向かうにつれて半径方向内方に傾斜し、上記雄部材の挿入時に上記リング状突部が押圧摺接する傾斜内面、及び上記雄部材と上記雌部材との結合時に上記リング状突部と係止して上記雄部材の抜けを規制する係止端部をそれぞれ有する、係止部材と、
上記ハウジングの外周面に軸直角方向から外装保持され、弾性変形により拡径可能なＣ字形状部、及び該Ｃ字形状部の両端部から内方に一体的に突出して、各上記爪部の各上記係止端部よりも上記ハウジングの軸方向奥側の位置で各上記窓部から上記ハウジング内にそれぞれ挿入される一対の係止突起部を有する、確認部材とからなり、
上記確認部材の各上記係止突起部は、上記雄部材が上記雌部材に結合される前の状態で上記窓部の周方向端部と係止して上記確認部材が上記ハウジングから軸直角方向に引き抜かれることを規制する第１係止部と、上記雄部材が上記雌部材に結合される前の状態で上記雄部材の挿入時における上記リング状突部の軌跡内に位置するとともに上記雄部材の挿入完了時に上記リング状突部で押圧されて半径方向外方に移動して上記Ｃ字形状部を拡径させる先端当接部と、上記雄部材の挿入完了時に上記窓部の周方向端縁と係止して上記Ｃ字形状部の弾性復帰力により上記確認部材が上記ハウジングから軸直角方向に外れることを規制するとともに、上記雄部材の挿入完了後で上記確認部材を上記ハウジングから軸直角方向に引き抜く際に上記窓部の周方向端縁との摺接を介して上記Ｃ字形状部をさらに拡径すべく、上記ハウジングの略求心方向に向かって傾斜して延在する傾斜第２係止部とをそれぞれ有し、
上記確認部材の各上記係止突起部の各上記第１係止部が上記窓部の周方向端部と係止して該確認部材が上記ハウジングに外装保持された状態で、上記Ｃ字形状部の内面が該ハウジングの側壁に圧接状態で密接するとともに、該側壁が各該第１係止部と該Ｃ字形状部の内面との間で軸直角方向に挟持されていることを特徴とするものである。
【０００９】
なお、本明細書において、軸方向とは雌部材の軸方向を意味し、周方向とは雌部材の周方向を意味する。
このコネクタでは、雄部材を雌部材に結合させる前の状態において、確認部材がハウジングの外周面に軸直角方向から外装保持されている。このとき、確認部材の各係止突起部は、係止部材の各爪部の係止端部よりもハウジングの軸方向奥側の位置で各窓部からハウジング内にそれぞれ挿入されるとともに、各係止突起部の第１係止部は、各窓部の周方向端部とそれぞれ係止している。このように、係止突起部の第１係止部が窓部の周方向端部と係止することにより、確認部材が軸直角方向に引き抜かれてハウジングから外れることを確実に規制することができ、この状態で確認部材を軸直角方向に引き抜いてハウジングから外そうとしても容易には外すことができない。また、この状態で、各係止突起部の先端当接部は、雄部材の挿入時におけるリング状突部の軌跡内に位置している。
【００１０】
そして、雄部材の挿入端部を雌部材のハウジング内に挿入開口端から挿入すると、雄部材のリング状突部は、係止部材の爪部の傾斜内面を押圧摺接することにより、爪部をその弾性に抗して半径方向外方に押し拡げ、爪部を通過する。これにより、爪部は半径方向内方に弾性復帰し、爪部の係止端部とリング状突部とが係止して、雄部材と雌部材とは係止部材を介して結合状態とされる。
【００１１】
この雄部材の挿入完了時においては、リング状突部の軌跡内に位置していた各係止突起部の先端当接部がリング状突部により押圧されて半径方向外方にそれぞれ移動し、これによりＣ字形状部が拡径される。このように確認部材のＣ字形状部が拡径すると、各係止突起部の傾斜第２係止部がハウジングの各窓部の周方向端縁にそれぞれ当接して係止される。このように、係止突起部の傾斜第２係止部が窓部の周方向端縁と係止することにより、Ｃ字形状部の弾性復帰力により確認部材がハウジングから軸直角方向に外れることを確実に規制することができる。
【００１２】
そして、この状態で確認部材を軸直角方向に引き抜ぬいてハウジングから外そうとすれば、各係止突起部の傾斜第２係止部と各窓部の周方向端縁との摺接を介して、Ｃ字形状部がさらに拡径されるので、確認部材をハウジングから軸直角方向に引き抜いて容易に外すことができる。これにより、雄部材と雌部材との結合を確認することができる。
【００１３】
このように、本発明のコネクタは、雄部材を雌部材に結合させた後に確認部材がその弾性復帰力によりハウジングから飛び出て外れるようなことがない。このため、結合後にハウジングから外れ落ちた確認部材を拾い集める作業が不要となる。
また、確認部材の各上記係止突起部の各上記第１係止部が上記窓部の周方向端部と係止して該確認部材が上記ハウジングに外装保持された状態で、上記Ｃ字形状部の内面が該ハウジングの側壁に圧接状態で密接するとともに、該側壁が各該第１係止部と該Ｃ字形状部の内面との間で軸直角方向に挟持されているので、確認部材はハウジングに強固に、かつ、確実に保持され、確認部材のハウジングに対する遊動等が阻止されるとともに、確認部材をハウジングから引き抜こうとしても容易には引き抜くことができないようにされている。
【００１４】
ここに、雄部材の挿入完了後に確認部材をハウジングから軸直角方向に引き抜く際、作業者は必ずしも垂直方向に引き抜くわけではない。例えば、コネクタの適用箇所等によっては、軸直角方向に対して軸方向の一端側又は他端側に傾いた斜め方向にしか引き抜けない場合もある。
かかる場合に、雄部材の挿入完了前、すなわち雄部材と雌部材との結合が完全（適正）に完了しておらず、確認部材の前記第１係止部と前記窓部の周方向端部とが未だ係止しているときに、軸直角方向に対して軸方向の一端側又は他端側に傾いた斜め方向に確認部材が引き抜かれると、ハウジングに対して軸直角方向に起立するように保持されたＣ字形状部が傾動し、その結果確認部材の第１係止部と窓部の周方向端部との係止が外れ易くなり、強く引っ張れば確認部材がハウジングから外れてしまうことも考えられる。このように、雄部材と雌部材との結合が完全に完了していないにもかかわらず、確認部材がハウジングから外れてしまっては、確認部材としての機能が果たされなくなる。
【００１５】
この点、このコネクタに係る確認部材は、Ｃ字形状部の周方向略中央から軸方向一端側及び他端側のうちの少なくとも一方に一体的に延設された少なくとも一つの傾動規制部が、ハウジングに対して軸直角方向に起立するように保持されたＣ字形状部の軸方向一端側及び他端側のうちの少なくとも一方への傾動を、少なくとも該ハウジングの外周面と当接することにより、規制する。
【００１６】
このため、雄部材の挿入完了前、すなわち雄部材と雌部材との結合が完全（適正）に完了しておらず、確認部材の前記第１係止部と前記窓部の周方向端部とが未だ係止しているときに、上記傾動規制部が延在する側の斜め方向に確認部材が引き抜かれた場合であっても、Ｃ字形状部が該引き抜き方向に傾動して確認部材の第１係止部と窓部の周方向端部との係止が外れ易くなることがない。したがって、確認部材としての機能が適切に果たされる。
（３）好適な態様において、本発明のコネクタは、前記傾動規制部が前記ハウジングの外周面に設けられた段部と係止する屈曲部を有している。この傾動規制部の屈曲部とハウジングの段部との係止により、ハウジングに対する確認部材の軸方向の位置決めがなされるとともに、Ｃ字形状部の軸方向一端側又は他端側への傾動がより確実に規制される。
（４）好適な態様において、本発明のコネクタは、前記確認部材が、前記Ｃ字形状部の周方向略中央から半径方向外方に一体的に延設され、該確認部材が前記ハウジングから軸直角方向に引き抜かれる際に引き抜き力が作用する取手部を有し、上記取手部は、前記雄部材の挿入完了前に上記確認部材を上記ハウジングから軸直角方向に引き抜こうとしたときに、該確認部材の前記第１係止部と前記窓部の周方向端部との係止が外れる前に該取手部を破損せしめるように設けられた少なくとも一つの切欠きを有していることを特徴とする。
【００１７】
ここに、雄部材の挿入完了前、すなわち雄部材と雌部材との結合が完全（適正）に完了しておらず、確認部材の前記第１係止部と前記窓部の周方向端部とが未だ係止しているときに、極端に強い力で確認部材が引き抜かれると、場合によっては確認部材の第１係止部等の破損を伴って又は伴わずに、確認部材がハウジングから外れてしまうことも考えられる。
【００１８】
かかる場合に、確認部材の破損部等がハウジングに保持されたまま残っていれば、雄部材と雌部材との結合が完全（適正）に完了していないことを確認することができる。しかし、このような確認部材の破損部等がハウジングに残っていない場合や確認部材が破損せずにそのままハウジングから外れてしまった場合は、雄部材と雌部材との結合が完全に完了した上で確認部材が正常に外されたのか、あるいは雄部材と雌部材との結合が完全に完了していないにもかかわらず確認部材が異常に外されたかの区別がつかず、確認部材としての機能が果たされなくなる。
【００１９】
この点、このコネクタに係る確認部材は、前記Ｃ字形状部の周方向略中央から半径方向外方に一体的に延設され、該確認部材が前記ハウジングから軸直角方向に引き抜かれる際に引き抜き力が作用する取手部を有し、この取手部は、前記雄部材の挿入完了前に上記確認部材を上記ハウジングから軸直角方向に引き抜こうとしたときに、該確認部材の前記第１係止部と前記窓部の周方向端部との係止が外れる前に該取手部を破損せしめるように設けられた少なくとも一つの切欠きを有している。
【００２０】
このため、このコネクタでは、雄部材の挿入完了前、すなわち雄部材と雌部材との結合が完全（適正）に完了していない状態で、作業者が上記取手部を極端に強い力で軸直角方向に引っ張った場合、確認部材の第１係止部と窓部の周方向端部との係止が外れる前に確認部材の取手部が上記切欠きの部分で破損し、破損した確認部材の少なくともＣ字形状部及び各係止突起部がハウジングに保持されたまま残存する。したがって、このような確認部材の破損部がハウジングに保持されたまま残存していることを目視等で確認することにより、雄部材と雌部材との結合が完全に完了していないことを確認することができる。
【００２１】
なお、雄部材と雌部材との結合が完全（適正に）に完了した場合は、作業者が手指等により確認部材の取手部を軸直角方向に引き抜けば、該取手部を破損させることなく、容易に確認部材をハウジングから外すことができる。
（５）好適な態様において、本発明のコネクタは、各前記係止突起部の前記Ｃ字形状部側の基端に凹状の欠切部が設けられている。
（６）請求項６記載のコネクタは、先端から所定の距離隔てた位置に遠心方向に突出するリング状突部が設けられた挿入端部をもつ筒状の雄部材と、
上記挿入端部が挿入される挿入開口端、及び半径方向に貫通し互いに対向するように周方向に配設された一対の窓部を有する略円筒状のハウジングを軸方向一端側に備えた雌部材と、
上記ハウジング内に挿入保持され、半径方向に弾性変形可能で上記窓部と対応する位置に配設された一対の爪部を有し、各該爪部は、上記挿入開口端から軸方向奥方に向かうにつれて半径方向内方に傾斜し、上記雄部材の挿入時に上記リング状突部が押圧摺接する傾斜内面、及び上記雄部材と上記雌部材との結合時に上記リング状突部と係止して上記雄部材の抜けを規制する係止端部をそれぞれ有する、係止部材と、
上記ハウジングの外周面に軸直角方向から外装保持され、弾性変形により拡径可能なＣ字形状部、及び該Ｃ字形状部の両端部から内方に一体的に突出して、各上記爪部の各上記係止端部よりも上記ハウジングの軸方向奥側の位置で各上記窓部から上記ハウジング内にそれぞれ挿入される一対の係止突起部を有する、確認部材とからなり、
上記確認部材の各上記係止突起部は、上記雄部材が上記雌部材に結合される前の状態で上記窓部の周方向端部と係止して上記確認部材が上記ハウジングから軸直角方向に引き抜かれることを規制する第１係止部と、上記雄部材が上記雌部材に結合される前の状態で上記雄部材の挿入時における上記リング状突部の軌跡内に位置するとともに上記雄部材の挿入完了時に上記リング状突部で押圧されて半径方向外方に移動して上記Ｃ字形状部を拡径させる先端当接部と、上記雄部材の挿入完了時に上記窓部の周方向端縁と係止して上記Ｃ字形状部の弾性復帰力により上記確認部材が上記ハウジングから軸直角方向に外れることを規制するとともに、上記雄部材の挿入完了後で上記確認部材を上記ハウジングから軸直角方向に引き抜く際に上記窓部の周方向端縁との摺接を介して上記Ｃ字形状部をさらに拡径すべく、上記ハウジングの略求心方向に向かって傾斜して延在する傾斜第２係止部とをそれぞれ有し、
上記確認部材が、上記Ｃ字形状部の周方向略中央から半径方向外方に一体的に延設され、該確認部材が上記ハウジングから軸直角方向に引き抜かれる際に引き抜き力が作用する取手部を有し、該取手部は、上記雄部材の挿入完了前に該確認部材を該ハウジングから軸直角方向に引き抜こうとしたときに、該確認部材の上記第１係止部と上記窓部の周方向端部との係止が外れる前に該取手部を破損せしめるように設けられた少なくとも一つの切欠きを有していることを特徴とするものである。
【００２２】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照しつつ具体的に説明する。
（実施形態１）
図１〜図１０に示す本実施形態のコネクタは、筒状の雄部材１と、ホース（ゴムあるいは樹脂チューブ等のホース）２の一端が固定された略円筒状の雌部材３と、雌部材３に内装され、雌部材３内に挿入された雄部材１を雌部材３に連結させるための係止部材４と、雌部材３に外装保持され、雌部材３に雄部材１が結合されたことを確認するための確認部材５とから構成されている。
【００２３】
雄部材１は、金属製又は樹脂製のパイプよりなり、図８に示すように、先端から所定の距離隔てた位置に遠心方向に突出するように設けられたリング状突部１ａと、このリング状突部１ａより先端側に位置する先端部１ｂとを備えた挿入端部１ｃを有している。
雌部材３は、樹脂（ナイロン）製で、図１及び図９に示すように、軸方向一端側（図１及び図９の右側、以下同様）に設けられたハウジング３１と、軸方向他端側（図１及び図９の左側、以下同様）にハウジング３１と同軸的に設けられたホース接続端部とから構成されている。そして、ハウジング３１は、軸方向一端側から順に同軸状に設けられた大径部３１ａ、中径部３１ｂ及び小径部３１ｃよりなり、上記雄部材１の上記挿入端部１ｃが挿入される挿入開口端３１ｄを軸方向一端側の端部に有している。また、ホース接続端部は内周面に軸穴を有し、ホース接続端部の外周面には環状の溝部とホース２の抜けを規制するための２つの段部とが設けられ、環状の溝部にはホース２の内周面をシールするリング状のシール部材が配設されている。そして、ホース接続端部の外周面に、上記ホース２が外装されている。
【００２４】
上記ハウジング３１の大径部３１ａの部分は、図２及び図１０に示すように、互いに平行に延びる一対の平坦壁部３１ｅ、３１ｅと、各平坦壁部３１ｅ、３１ｅの上端及び下端同士をそれぞれ一体的に接続する一対の円弧壁部３１ｆ、３１ｆとからなる。そして、各円弧壁部３１ｆ、３１ｆの周方向中央部には、半径方向に貫通し互いに対向するように周方向に配設された長方形状の窓部３５、３５がそれぞれ設けられている。
【００２５】
なお、ハウジング３１の軸直角断面において、相互に対向するように配設された両窓部３５、３５の該対向方向と平行に延びる中心軸を第１の対称軸Ｐとし、この対称軸Ｐと直交する第２の対称軸Ｑとした場合、上記両平坦壁部３１ｅ、３１ｅは、この第１の対称軸Ｐと平行に延びている。また、上記両窓部３５、３５の二組の周方向端部３５ａ、３５ａは、上記第１の対称軸Ｐと平行に延びる対向平行面とされている。上記両窓部３５、３５は、上記第２の対称軸Ｑに対しても対称に形成されている。これらの構成により、ハウジング３１の大径部３１ａの部分（本実施形態では、ハウジング３１を含む雌部材３）は、第１の対称軸Ｐに対して対称形状とされるとともに、第２の対称軸Ｑに対しても対称形状とされている。そして、確認部材５も後述するように第２の対称軸Ｑに対して対称形状とされていることから（図２参照）、ハウジング３１に対して、確認部材５を図２の右側からでも左側からでも装着することが可能となる。
【００２６】
上記中径部３１ｂの内周面には、長円筒状のカラー部材３６、上記ハウジング３１に挿入された上記挿入端部１ｃの上記先端部１ｂの外周面をシールするリング状のシール部材３７、短円筒状のカラー部材３８及び同じく上記先端部１ｂの外周面をシールするリング状のシール部材３７が軸方向一端側から順に配設されている。また、上記小径部３１ｃの内周面は上記ハウジング３１に挿入された上記挿入端部１ｃの上記先端部１ｂの外周面と嵌合するリング状の嵌合内周面とされている。
【００２７】
上記係止部材４は、弾性変形可能な樹脂（ナイロン）製部材よりなり、上記ハウジング３１の大径部３１ａ内に挿入保持されている。係止部材４は、図７に示すように、環状カラー部４１と、この環状カラー部４１から相対向するようにそれぞれ突出する一対の略コ字状部４２、４２と、各略コ字状部４２、４２からそれぞれ軸芯に対して半径方向内方に傾斜するように突出し、半径方向に弾性変形可能な一対の爪部４３、４３とから構成されている。そして、爪部４３は、係止部材４がハウジング３１内に挿入保持された状態で、挿入開口端３１ｄから軸方向奥方に向かうにつれて半径方向内方に傾斜し、雄部材１の挿入時にリング状突部１ａが押圧摺接する傾斜内面４３ａと、雄部材１と雌部材３との結合時にリング状突部１ａと係止して雄部材１の抜けを規制する係止端部４３ｂと、ハウジング１の窓部３５の周方向端部３５ａと係止して係止部材４の抜けを規制する係止段部４３ｃとを有している。なお、係止部材４は、ハウジング３１内への挿入のし易さを考慮して、ハウジング３１に対して軸方向に相対移動可能に保持されている。
【００２８】
上記確認部材５は、図４〜図６に示すように、弾性変形により拡径可能なＣ字形状部５１と、Ｃ字形状部５１の両端部から内方に一体的に突出された一対の係止突起部５２、５２と、Ｃ字形状部５１の周方向中央から半径方向外方に一体的に延設され、確認部材５がハウジング３１から引き抜かれる際に手指等が掛けられて引き抜き力が作用するリング状の取手部５３とを有しており、Ｃ字形状部５１、係止突起部５２及び取手部５３は一体的に形成されている。
【００２９】
そして、この確認部材５は、Ｃ字形状部５１を拡径することにより、Ｃ字形状部５１の両端部の係止突起部５２、５２を窓部３５、３５から挿入して、図２に示すようにハウジング３１に装着することができる。上記Ｃ字形状部５１の内周面形状はハウジング３１の大径部３１ａの外周面形状と対応しており、確認部材５がハウジング３１に外装保持された状態で、Ｃ字形状部５１の内周面は大径部３１ａの外周面と圧接状態で密接している（後述する）。なお、この確認部材５は、図４から明らかなように、Ｃ字形状部５１の周方向の中心央及び両係止突起部５２、５２間の中心を通る中心線（図４のＢ−Ｂ線）を対称軸とした対称形状とされている。
【００３０】
各上記係止突起部５２、５２は、雄部材１が雌部材３に結合される前の状態で窓部３５の周方向端部３５ａと係止して確認部材５がハウジング３１から軸直角方向（図２の第２の対称軸Ｑ方向、以下同様）に引き抜かれることを規制する第１係止部５２ａ、５２ａと、雄部材１が雌部材３に結合される前の状態で雄部材１の挿入時におけるリング状突部１ａの軌跡内に位置するとともに雄部材１の挿入完了時にリング状突部１ａで押圧されて半径方向外方に移動してＣ字形状部５１を拡径させる先端当接部５２ｂ、５２ｂと、雄部材１の挿入完了時に窓部３５の周方向端縁３５ｂと係止してＣ字形状部５１の弾性復帰力により確認部材５がハウジング３１から軸直角方向に外れることを規制するとともに、雄部材１の挿入完了後で確認部材５をハウジング３１から軸直角方向に引き抜く際に窓部３５の周方向端縁３５ｂとの摺接を介してＣ字形状部５１をさらに拡径すべく、ハウジング３１の略求心方向に向かって傾斜して延在する傾斜第２係止部５２ｃ、５２ｃとをそれぞれ有している。
【００３１】
なお、確認部材５がハウジング３１に外装保持された状態において、係止突起部５２は、上記爪部４３の上記係止端部４３ｂよりも上記ハウジング３１の軸方向奥側の位置で、上記窓部３５から上記ハウジング３１内にそれぞれ挿入される。また、本実施形態では、各係止突起部５２の先端当接部５２ｂは、確認部材５がハウジング３１に外装保持され、かつ、雄部材１が雌部材３に結合される前の状態で、挿入される雄部材１の先端部１ｂの外周面と摺接可能な位置までハウジング３１内に進入している。
【００３２】
ここで、本実施形態では、各係止突起部５２のＣ字形状部５１側（図４及び図６の上側）の基端（係止突起部５２とＣ字形状部５１と境界）には凹状の欠切部５４（図６参照）が設けられており、この欠切部５４と傾斜第２係止部５２ｃとの境界部が第１係止部５２ａとされている。また、各窓部３５の各周方向端部３５ａ同士を結ぶ直線と、ハウジング３１の平坦部３１ｅの外面との距離は、各第１係止部５２ａ、５２ａ同士を結ぶ直線と、Ｃ字形状部５１の平坦部の内面との距離よりも若干大きくなるように、上記Ｃ字形状部５１やハウジング３１等の寸法が設定されている。これらの構成により、確認部材５がハウジング３１に外装保持された状態、すなわち確認部材５の各係止突起部５２の各第１係止部５２ａが窓部３５の周方向端部３５ａと係止した状態で、確認部材５のＣ字形状部５１は若干弾性変形しており、この弾性力が各第１係止部５２ａを各窓部３５の各周方向端部３５ａに対して略直角方向に押圧する力として作用している。その結果、確認部材５の各第１係止部５２ａとＣ字形状部５１の内面との間で、確認部材５が装着された側のハウジング３１の大径部３１ａの側壁、すなわちＣ字形状部５１の内面が圧接状態に密接している大径部３１ａの側壁が、軸直角方向に挟持されている。これにより、確認部材５はハウジング３１に強固に、かつ、確実に保持され、確認部材５のハウジング３１に対する遊動等が阻止されるとともに、確認部材５をハウジング３１から引き抜こうとしても容易には引き抜くことができないようにされている。
【００３３】
なお、上記欠切部５４を形成すること、及び確認部材５をハウジング３１に外装保持させた状態でＣ字形状部５１が若干弾性変形するように寸法設計することは、本発明の必須要件ではない。ただし、確認部材５をハウジング３１に外装保持させた状態でＣ字形状部５１が若干弾性変形するように寸法設計する場合は、上記欠切部５４を形成することが好ましい。上記欠切部５４が形成されていないと、Ｃ字形状部５１の弾性復帰力が、第１係止部５２ａと窓部３５の周方向端部３５ａとの係止部を介して、Ｃ字形状部５１を拡径させる方向に作用することになるため、確認部材５がハウジング３１から外れ易くなるからである。
【００３４】
また、本実施形態では、各係止突起部５２の先端側の両側面は、先端に向かうにつれて互いの間隔が狭まるテーパ面５５、５５とされている。このため、雄部材１の挿入時、リング状突部１ａがテーパ面５５に摺接、案内されて先端当接部５２ｂの内側に入り込み易くなっており、リング状突部１ａにより先端当接部５２ｂを半径方向外方に移動させ易くなっている。
【００３５】
このコネクタでは、雄部材１を雌部材３に結合させる前の状態において、図１〜図３に示すように、確認部材５がハウジング３１の外周面に軸直角方向から外装保持されている。このとき、確認部材５の各係止突起部５２は、係止部材４の各爪部４３の係止端部４３ｂよりもハウジング３１の軸方向奥側の位置で各窓部３５からハウジング３１内にそれぞれ挿入されるとともに、各係止突起部５２の第１係止部５２ａは、各窓部３５の周方向端部３５ａとそれぞれ係止している。このように、係止突起部５２の第１係止部５２ａが窓部３５の周方向端部３５ａと係止することにより、確認部材５がハウジング３１から軸直角方向に引く抜かれることを確実に規制することができ、この状態で確認部材５をハウジング３１から軸直角方向に引き抜こうとしても引き抜くことはできない。また、この状態で、各係止突起部５２の先端当接部５２ｂは、雄部材１の挿入時におけるリング状突部１ａの軌跡内に位置している。
【００３６】
そして、雄部材１の挿入端部１ｃを雌部材３のハウジング３１内に挿入開口端３１ｄから挿入すると、雄部材１のリング状突部１ａは、係止部材４の各爪部４３の各傾斜内面４３ａを押圧摺接することにより、各爪部４３をその弾性に抗して半径方向外方に押し拡げ、各爪部４３を通過する。これにより、各爪部４３は半径方向内方に弾性復帰し、各爪部４３の係止端部４３ｂとリング状突部１ａとが係止して、雄部材１と雌部材３とは係止部材４を介して結合状態とされる。
【００３７】
この雄部材１の挿入完了時においては、図９及び図１０に示すように、リング状突部１ａの軌跡内に位置していた各係止突起部５２の各先端当接部５２ｂがリング状突部１ａにより押圧されて半径方向外方にそれぞれ移動し、これによりＣ字形状部５１が拡径される。このように確認部材５のＣ字形状部５１が拡径すると、各係止突起部５２の各傾斜第２係止部５２ｃがハウジング３１の各窓部３５の周方向端縁３５ｂにそれぞれ当接して係止される。このように、係止突起部５２の傾斜第２係止部５２ｃが窓部３５の周方向端縁３５ｂと係止することにより、Ｃ字形状部５１の弾性復帰力により確認部材５がハウジング３１から軸直角方向に外れることを確実に規制することができる。
【００３８】
そして、この状態で確認部材５をハウジング３１から軸直角方向に引き抜こうとすれば、各係止突起部５２の各傾斜第２係止部５２ｃと各窓部３５の各周方向端縁３５ｂとの摺接を介して、Ｃ字形状部５１がさらに拡径されるので、確認部材５をハウジング３１から軸直角方向に容易に引き抜くことができる。これにより、雄部材１と雌部材３との結合を確認することができる。
【００３９】
このように、本実施形態のコネクタは、雄部材１を雌部材３に結合させた後に確認部材５がその弾性復帰力によりハウジング３１から飛び出て外れるようなことがない。このため、結合後にハウジング３１から外れ落ちた確認部材５を拾い集める作業が不要となる。したがって、本実施形態のコネクタは、確認部材５が外れ落ちては困るような箇所や外れ落ちた確認部材５を拾い集めるのが困難な箇所等にも適用することが可能となる。
【００４０】
（実施形態２）
図１１〜図１３に示す本実施形態のコネクタは、確認部材５が第１及び第２傾動規制部５６及び５７を有しているものである。すなわち、この確認部材５は、Ｃ字形状部５１の周方向中央から軸方向一端側及び他端側に棒状の第１及び第２傾動規制部５６及び５７が一体的に延設されている。軸方向一端側に延設された第１傾動規制部５６は、ハウジング３１の大径部３１ａの軸方向略中央まで延びており、一方、軸方向他端側に延設された第２傾動規制部５７は、大径部３１ａの軸方向他端側の段部３１ｅまで延びて、その先端に屈曲部５７ａが設けられている。そして、確認部材５がハウジング３１に外装保持された状態で、第１及び第２傾動規制部５６及び５７の内面は大径部３１ａの外周面と当接しており、かつ、第２傾動規制部７６の屈曲部５７ａは大径部３１ａの軸方向他端側の段部３１ｅと係止されている。なお、第２傾動規制部５７の屈曲部５７ａと大径部３１ａの段部３１ｅとの係止により、ハウジング３１に対する確認部材５の軸方向の位置決めがなされる。
【００４１】
このコネクタに係る確認部材５では、Ｃ字形状部５１の周方向中央から軸方向一端側及び他端側に一体的に延設された第１及び第２傾動規制部５６及び５７が、ハウジング３１に対して軸直角方向に起立するように保持されたＣ字形状部５１の軸方向一端側又は他端側への傾動を、少なくともハウジング３１の大径部３１ａの外周面と当接することにより、規制する。詳しくは、Ｃ字形状部５１の軸方向一端側への傾動は、軸方向一端側に延設された第１傾動規制部５６の内面が大径部３１ａの外周面と当接することにより規制され、一方Ｃ字形状部５１の軸方向他端側への傾動は、軸方向他端側に延設された第２傾動規制部５７の内面が大径部３１ａの外周面と当接することにより規制される。特に、この確認部材５では、軸方向他端側に延設された第２傾動規制部５７の屈曲部５７ａが大径部３１ａの段部３１ｅと係止していることから、Ｃ字形状部５１の軸方向一端側及び他端側への傾動がより確実に規制される。
【００４２】
このため、雄部材１の挿入完了前、すなわち雄部材１と雌部材３との結合が完全（適正）に完了しておらず、確認部材５の前記第１係止部５２ａと前記窓部３５の周方向端部３５ａとが未だ係止しているときに、軸直角方向に対して軸方向一端側及び他端側のいずれに傾いた斜め方向に確認部材５が引き抜かれた場合であっても、Ｃ字形状部５１が該引き抜き方向に傾動して確認部材５の第１係止部５２ａと窓部３５の周方向端部３５ａとの係止が外れ易くなることがない。したがって、雄部材１と雌部材３との結合が完全に完了していないにもかかわらず、確認部材５が斜め方向に強く引き抜かれることによりハウジング３１から外れてしまうようなことがなく、確認部材５としての機能が適切に果たされる。
【００４３】
その他の構成及び作用効果は、上記実施形態１と同様である。
（実施形態３）
図１４に示す本実施形態のコネクタは、上記実施形態２に係る確認部材５において、第１傾動規制部５６も大径部３１ｅの軸方向一端側の段部３１ｅまで延びて、その先端に屈曲部５６ａが設けられている。
【００４４】
したがって、第１及び第２傾動規制部５６及び５７の屈曲部５６ａ及び５７ａを大径部３１ａの軸方向両側の段部３１ｅ及び３１ｅにそれぞれ係止させることにより、ハウジング３１に対する確認部材５の軸方向の位置決めを確実に行いうるとともに、ハウジング３１に対する確認部材５の軸方向の相対移動を確実に阻止することができる。また、上記実施形態２で説明したＣ字形状部５１の傾動についても、軸方向の両側でより確実に規制することができる。
【００４５】
その他の構成及び作用効果は、上記実施形態２と同様である。
（実施形態４）
図１５に示す本実施形態のコネクタは、上記実施形態２において、大径部３１ａの段部３１ｅに係止された第２傾動規制部５７の屈曲部５７ａと当接しうるように、ハウジング３１の中径部３１ｂの所定位置に環状の当接規制体３２を固定したものである。
【００４６】
したがって、第２傾動規制部５７の屈曲部５７ａが当接規制体３２と当接することにより、Ｃ字形状部５１の軸方向一端側及び他端側への傾動をさらに確実に規制することが可能となる。
その他の構成及び作用効果は、上記実施形態２と同様である。
（実施形態５）
図１６に示す本実施形態のコネクタは、上記実施形態１に係る確認部材５において、取手部５３を構成するリング部５３ａと、リング部５３ａ及びＣ字形状部５１を接続する首部５３ｂとの間の境界部であって、該リング部５３ａ側に一つの切欠き５３ｃを設けたものである。
【００４７】
この切欠き５３ｃは、雄部材１の挿入完了前、すなわち雄部材１と雌部材３との結合が完全（適正）に完了しておらず、確認部材５の前記第１係止部５２ａと前記窓部３５の周方向端部３５ａとが未だ係止している状態で、確認部材５をハウジング３１から軸直角方向に引き抜こうとしたときに、確認部材５の第１係止部５２ａと窓部３５の周方向端部３５ａとの係止が外れる前に取手部５３のリング部５３ａを破断せしめるように設けられている。
【００４８】
さらに言うならば、雄部材１の挿入完了後、すなわち雄部材１と雌部材３との結合が完全（適正）に完了して、Ｃ字形状部５１の拡径により前記傾斜第２係止部５２ｃと前記窓部３５の周方向端縁３５ｂとが係止している状態で、確認部材５をハウジング３１から軸直角方向に引き抜く際には上記取手部５３のリング部５３ａを破断せしめないように、上記切欠き５３ｃが設けられている。
このため、このコネクタでは、雄部材１の挿入完了前、すなわち雄部材１と雌部材３との結合が完全（適正）に完了していない状態で、作業者が上記取手部５３のリング部５３ａに手指等を引っかけて極端に強い力で軸直角方向に引っ張った場合、確認部材５の第１係止部５２ａと窓部３５の周方向端部３５ａとの係止が外れる前に取手部５３のリング部５３ａが上記切欠き５３ｃの部分で破損（切断）する。このとき、作業者の手指等がリング部５３ａから外れれば、作業者は確認部材５をそれ以上引っ張ることができず、上記切欠き５３ｃの部分で破損した確認部材５がそのままハウジング３１に保持されたまま残る。したがって、その後に作業する者は、切欠き５３ｃの部分で破損した確認部材５がハウジング３１に保持されていることを視認等することにより、雄部材１と雌部材３との結合が完了していないことを確認することができる。
【００４９】
なお、雄部材１と雌部材３との結合が完全（適正に）に完了した場合は、作業者が手指等により確認部材５の取手部５３のリング部５３ａを軸直角方向に引き抜けば、取手部５３のリング部５３ａを切欠き５３ｃの部分で破損させることなく、確認部材５をハウジング３１から容易に外すことができる。
その他の構成及び作用効果は、上記実施形態１と同様である。
【００５０】
（実施形態６）
図１７に示す本実施形態のコネクタは、上記実施形態４に係る確認部材５において、取手部５３を構成するリング部５３ａと、リング部５３ａ及びＣ字形状部５１を接続する首部５３ｂとの間の境界部であって、該首部５３ｂ側に該首部５３ｂの幅方向に相互に対向する一対の切欠き５３ｃ、５３ｃを設けたものである。
【００５１】
この切欠き５３ｃは、上記実施形態５で説明した切き５３ｃと同様、雄部材１の挿入完了前に確認部材５をハウジング３１から軸直角方向に引き抜こうとすれば、確認部材５の第１係止部５２ａと窓部３５の周方向端部３５ａとの係止が外れる前に取手部５３の首部５３ｂを破断せしめるように設けられ、かつ、雄部材１の挿入完了後に確認部材５をハウジング３１から軸直角方向に引き抜く際には上記取手部５３の首部５３ｂを破断せしめないように設けられている。
【００５２】
このため、このコネクタでは、雄部材１の挿入完了前、すなわち雄部材１と雌部材３との結合が完全（適正）に完了していない状態で、作業者が上記取手部５３のリング部５３ａに手指等を引っかけて極端に強い力で軸直角方向に引っ張った場合、確認部材５の第１係止部５２ａと窓部３５の周方向端部３５ａとの係止が外れる前に取手部５３の首部５３ｂが上記切欠き５３ｃの部分で破断し、確認部材５のうち首部５３ｂの一部、Ｃ字形状部５１及各係止突起部５２の部分がハウジング３１に保持されたまま残る。したがって、その後に作業する者は、このように破損した確認部材５がハウジング３１に保持されていることを視認等することにより、雄部材１と雌部材３との結合が完了していないことを容易に確認することができる。
【００５３】
なお、雄部材１と雌部材３との結合が完全（適正に）に完了した場合は、作業者が手指等により確認部材５の取手部５３のリング部５３ａを軸直角方向に引き抜けば、取手部５３の首部５３ｂを切欠き５３ｃの部分で破損させることなく、容易に確認部材５をハウジング３１から外すことができる。
その他の構成及び作用効果は、上記実施形態４と同様である。
【００５４】
【発明の効果】
以上詳述したように本発明のコネクタにおいては、雄部材を雌部材に結合させた後に確認部材がその弾性復帰力によりハウジングから飛び出て外れるようなことがないため、結合後にハウジングから外れ落ちた確認部材を拾い集める作業が不要となる。したがって、本発明のコネクタは、確認部材が外れ落ちては困るような箇所や外れ落ちた確認部材を拾い集めるのが困難な箇所等にも適用することが可能となる。
【００５５】
また、確認部材に傾動規制部を設けた場合は、雄部材と雌部材との結合が完全に完了していない状態で確認部材が斜め方向に引き抜かれた際でも、Ｃ字形状部の傾動が規制されるので、確認部材の第１係止部と窓部の周方向端部との係止が外れ易くなることがなく、したがって、確認部材として適切に機能させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a connector for connecting hoses, pipes and the like for piping, and more particularly to a connector capable of confirming a connection state between a male member and a female member.
[0002]
[Prior art]
As connectors for connecting hoses and the like, those shown in FIGS. 18 and 19 are known. This connector has a substantially cylindrical shape having a pipe-shaped male member 80 provided with a ring-shaped projecting portion 80a projecting in a centrifugal direction at a predetermined distance from the tip, and an insertion opening end 81a into which the male member 80 is inserted. A female member 82 having a housing 81 and a locking member 83 for connecting and holding the male member 80 inserted and held in the insertion opening end 81 a side of the housing 81 and inserted into the housing 81 to the female member 82. And a confirmation member 84 that is externally held on the outer peripheral surface of the housing 81 from the direction perpendicular to the axis and that confirms that the male member 80 is coupled to the female member 82.
[0003]
A pair of windows 81b are provided at the end of the housing 81 on the insertion opening end 81a side so as to penetrate in the radial direction and face each other so that the locking member 83 is elastic in the radial direction. It has a pair of claw portions 83a that can be deformed and disposed at a position corresponding to the window portion 81b. Further, as shown in FIG. 19, the confirmation member 84 has a substantially C shape that can be expanded by elastic deformation, and is provided in a notch groove 81 c that is continuously provided at the end of the window portion 81 b of the housing 81. It is inserted inside and is externally held on the outer peripheral surface of the housing 81 from the direction perpendicular to the axis. The confirmation member 84 is engaged with the edge of the window portion 81b before the male member 80 is coupled to the female member 82, and the confirmation member 84 is detached from the housing 81 in the direction perpendicular to the axis. It has a pair of locking recesses 84a for restricting this, and a pair of tip contact portions 84b with which the outer peripheral surface of the ring-shaped protrusion 80a contacts when the male member 80 is inserted.
[0004]
In this connector, the confirmation member 84 is externally held on the outer peripheral surface of the housing 81 from the direction perpendicular to the axis before the male member 80 is coupled to the female member 82, and the locking recess 84 a of the confirmation member 84 is the window of the housing 81. The front end abutting portion 84b of the confirmation member 84 is inserted in the window portion 81b at a position deeper in the axial direction than the claw portion 83a of the engaging member 83 while being locked to the edge of the portion 81b. In this state, when the male member 80 is inserted into the housing 81 of the female member 82, the ring-shaped protrusion 80a of the male member 80 causes the claw portion 83a of the locking member 83 to resist its elasticity outward in the radial direction. It spreads and passes through the claw part 83a. Thereby, the front-end | tip of the nail | claw part 83a and the ring-shaped protrusion 80a latch, and the male member 80 and the female member 82 will be in a connection state. In this coupled state (the state shown in FIGS. 18 and 19), the ring-shaped protrusion 80a of the male member 80 expands the tip contact portion 84b of the confirmation member 84 radially outward. Then, the locking recess 84a of the confirmation member 84 is disengaged from the edge of the window portion 81b, and the confirmation member 84 is popped out by the elasticity in the direction perpendicular to the axis (the arrow direction in FIG. 19). Thereby, it can be confirmed that the male member 80 is coupled to the female member 82.
[0005]
[Problems to be solved by the invention]
As described above, in the conventional connector, when the male member 80 is coupled to the female member 82, the confirmation member 84 is disengaged from the housing 81 in the direction perpendicular to the axis by the elastic restoring force, so that the male member 80 is connected to the female member 82. This is to confirm that they are combined.
In the conventional connector described above, in order to make the confirmation member 84 easily disengage from the housing 81 in the direction perpendicular to the axis, a notch groove 81c is provided in the housing 81 to narrow the circumferential width of the side wall of the housing 81 over which the confirmation member 84 straddles. Alternatively, an intermediate member is separately provided on the inner surface side of the tip contact portion 84b of the confirmation member 84, and the tip contact portion 84b of the confirmation member 84 is radially outwardly moved by the ring-shaped protrusion 80a via this intermediate member. It has been devised to expand it.
[0006]
However, at the same time when the male member 80 is coupled to the female member 82, if the confirmation member 84 is detached from the housing 81 due to its elastic restoring force, it is necessary to collect the confirmation member 84 that has fallen off the housing 81 after the coupling. There are cases where this is extremely difficult depending on where the connector is applied. Further, the conventional connector cannot be applied to a place where it is difficult for the confirmation member 84 to come off.
[0007]
The present invention has been made in view of the above circumstances, and it is a technical problem to be solved to provide a connector in which a confirmation member does not pop out due to its elasticity after a male member and a female member are coupled. It is.
[0008]

  Each of the locking protrusions of the confirmation member is locked with the circumferential end of the window before the male member is coupled to the female member, and the confirmation member is perpendicular to the housing from the housing. A first locking portion that restricts the male member from being pulled out, and the male member is positioned within the locus of the ring-shaped protrusion when the male member is inserted in a state before the male member is coupled to the female member. A tip abutting portion that is pressed by the ring-shaped protrusion when the member insertion is completed and moves radially outward to increase the diameter of the C-shaped portion, and a circumferential direction of the window portion when the male member is completely inserted The confirmation member is prevented from coming off from the housing by the elastic restoring force of the C-shaped portion by engaging with the end edge, and the confirmation member is removed from the housing after the male member is completely inserted. When pulling out in the direction perpendicular to the axis, the window To further expanded the C-shaped portions through a sliding contact with the circumferential edge, respectively perforated and an inclined second engaging portion extending inclined toward the substantially centripetal direction of the housingAnd
  In the state where each first locking portion of each locking protrusion of the checking member is locked to the circumferential end of the window portion and the checking member is externally held on the housing, the C-shaped The inner surface of the portion is in close contact with the side wall of the housing in a press-contact state, and the side wall is sandwiched between the first locking portion and the inner surface of the C-shaped portion in the direction perpendicular to the axis.It is characterized by that.
[0009]
In addition, in this specification, an axial direction means the axial direction of a female member, and the circumferential direction means the circumferential direction of a female member.
In this connector, the confirmation member is externally held on the outer peripheral surface of the housing from the direction perpendicular to the axis before the male member is coupled to the female member. At this time, each locking projection of the confirmation member is inserted into the housing from each window at a position on the back side in the axial direction of the housing from the locking end of each claw of the locking member, and The 1st latching | locking part of the latching protrusion part is each latching with the circumferential direction edge part of each window part. As described above, the first locking portion of the locking projection portion locks with the circumferential end portion of the window portion, so that the confirmation member can be reliably restricted from being pulled out in the direction perpendicular to the axis and coming off the housing. In this state, even if the confirmation member is pulled out in the direction perpendicular to the axis to be removed from the housing, it cannot be easily removed. Further, in this state, the tip contact portion of each locking projection is located within the locus of the ring-shaped projection when the male member is inserted.
[0010]
Then, when the insertion end of the male member is inserted into the housing of the female member from the insertion opening end, the ring-shaped protrusion of the male member presses and slides on the inclined inner surface of the claw of the locking member, thereby It resists its elasticity and spreads outward in the radial direction and passes through the claw portion. As a result, the claw portion elastically returns inward in the radial direction, the locking end portion of the claw portion and the ring-shaped protrusion are locked, and the male member and the female member are in a coupled state via the locking member. Is done.
[0011]
When the insertion of the male member is completed, the tip contact portion of each locking projection that was located in the locus of the ring-shaped protrusion is pressed by the ring-shaped protrusion and moved outward in the radial direction, Thereby, a C-shaped part is expanded in diameter. When the diameter of the C-shaped portion of the confirmation member is increased in this way, the inclined second locking portion of each locking projection is brought into contact with and locked to the circumferential edge of each window portion of the housing. As described above, the inclined second locking portion of the locking projection portion is locked to the circumferential edge of the window portion, so that the confirmation member is detached from the housing in the direction perpendicular to the axis by the elastic return force of the C-shaped portion. Can be reliably regulated.
[0012]
In this state, if the confirmation member is pulled out in the direction perpendicular to the axis to be removed from the housing, the sliding contact between the inclined second locking portion of each locking projection and the circumferential edge of each window portion will occur. Since the diameter of the C-shaped portion is further expanded, the confirmation member can be easily pulled out from the housing in the direction perpendicular to the axis. Thereby, the coupling | bonding of a male member and a female member can be confirmed.
[0013]
  Thus, in the connector of the present invention, after the male member is coupled to the female member, the confirmation member does not jump out of the housing due to its elastic restoring force. For this reason, the operation | work which collects the confirmation member which fell out of the housing after coupling | bonding becomes unnecessary.
  In addition, each of the first locking portions of each of the locking protrusions of the confirmation member is locked to the circumferential end of the window portion, and the confirmation member is externally held by the housing. Check that the inner surface of the shape portion is in close contact with the side wall of the housing in a pressure contact state, and that the side wall is sandwiched between the first locking portion and the inner surface of the C-shaped portion in the direction perpendicular to the axis. The member is firmly and securely held in the housing, prevents the check member from moving freely with respect to the housing, and prevents the check member from being easily pulled out even if the check member is pulled out of the housing.
[0014]
Here, when the confirmation member is pulled out from the housing in the direction perpendicular to the axis after the male member has been inserted, the operator does not necessarily pull out in the vertical direction. For example, depending on the location where the connector is applied, the connector may be pulled out only in an oblique direction inclined toward one end side or the other end side in the axial direction with respect to the direction perpendicular to the axis.
In such a case, the insertion of the male member is not completed, that is, the coupling between the male member and the female member is not completely (proper) completed, and the first locking portion of the confirmation member and the circumferential end of the window portion When the confirmation member is pulled out in an oblique direction inclined toward one end side or the other end side in the axial direction with respect to the direction perpendicular to the axis, As a result, the C-shaped portion held by the tilter is easily tilted. As a result, the locking between the first locking portion of the confirmation member and the circumferential end of the window portion is easily released. It is also possible. Thus, even if the coupling between the male member and the female member is not completely completed, if the confirmation member is detached from the housing, the function as the confirmation member is not fulfilled.
[0015]
In this respect, the confirmation member according to this connector has at least one tilt restricting portion integrally extended from at least one of the one end side and the other end side in the axial direction from the substantially center in the circumferential direction of the C-shaped portion. By tilting the C-shaped part held so as to stand upright in the direction perpendicular to the housing to at least one of the one end side and the other end side in the axial direction at least in contact with the outer peripheral surface of the housing, regulate.
[0016]
  For this reason, before the insertion of the male member, that is, the coupling between the male member and the female member is not completely (proper) completed, the first locking portion of the confirmation member and the circumferential end of the window portion Even when the confirmation member is pulled out in the oblique direction on the side where the tilt restricting portion extends, the C-shaped portion is tilted in the pulling direction and the confirmation member The locking between the first locking portion and the circumferential end of the window portion does not easily come off. Therefore, the function as a confirmation member is performed appropriately.
(3) In a preferred embodiment, the connector of the present invention isThe tilt restricting portion has a bent portion that engages with a step portion provided on the outer peripheral surface of the housing. By locking the bent portion of the tilt restricting portion and the stepped portion of the housing, the confirmation member is axially positioned with respect to the housing, and the tilt of the C-shaped portion toward one end side or the other end side in the axial direction is further increased. Regulated reliably.
(4) In a preferred aspect, in the connector of the present invention, the confirmation member is integrally extended radially outward from a substantially center in the circumferential direction of the C-shaped portion, and the confirmation member is pivoted from the housing. A pulling force acting when pulling out in a right angle direction, and the pulling portion checks when the check member is pulled out from the housing in a direction perpendicular to the axis before the male member is completely inserted. It has at least one notch provided so as to damage the handle portion before the first locking portion of the member and the circumferential end of the window portion are released. To do.
[0017]
Here, before completion of the insertion of the male member, that is, the coupling between the male member and the female member is not completely (proper) completed, the first locking portion of the confirmation member and the circumferential end of the window portion If the confirmation member is pulled out with an extremely strong force while it is still locked, the confirmation member may come off the housing with or without damage to the first locking portion of the confirmation member. It can be considered.
[0018]
In such a case, if the damaged portion or the like of the confirmation member remains held in the housing, it can be confirmed that the coupling between the male member and the female member is not completely (proper) completed. However, when such a damaged part of the confirmation member does not remain in the housing or when the confirmation member is not damaged and is detached from the housing as it is, the coupling between the male member and the female member is completely completed. In this case, it cannot be distinguished whether the confirmation member has been removed normally or whether the confirmation member has been removed abnormally even though the connection between the male member and the female member has not been completely completed. It will not be fulfilled.
[0019]
In this respect, the confirmation member according to this connector is integrally extended radially outward from the substantially center in the circumferential direction of the C-shaped portion, and is pulled out when the confirmation member is pulled out from the housing in the direction perpendicular to the axis. A handle portion on which a force acts, and the handle portion is configured to remove the confirmation member from the housing in a direction perpendicular to the axis before the male member is completely inserted; And at least one notch provided so as to damage the handle portion before the engagement between the window portion and the circumferential end of the window portion is released.
[0020]
For this reason, in this connector, before the male member is completely inserted, that is, in a state where the coupling between the male member and the female member is not completely (appropriately completed), the operator holds the handle portion at a right angle with an extremely strong force. When pulling in the direction, the handle of the confirmation member is damaged at the notch before the first engagement portion of the confirmation member and the circumferential end of the window are released, and the broken confirmation member At least the C-shaped portion and each locking projection remain while being held by the housing. Therefore, it is confirmed by visual check that the damaged portion of the confirmation member remains retained in the housing, thereby confirming that the coupling between the male member and the female member is not completely completed. be able to.
[0021]
  In addition, when the coupling between the male member and the female member is completed completely (appropriately), if the operator pulls out the handle portion of the confirmation member with the fingers or the like in the direction perpendicular to the axis, the handle portion is not damaged. The confirmation member can be easily removed from the housing.
(5) In a preferred aspect, the connector according to the present invention is provided with a concave notch at the base end of each locking projection on the C-shaped part side.
(6) The connector according to claim 6 is a cylindrical male member having an insertion end provided with a ring-shaped protrusion protruding in the centrifugal direction at a position separated from the tip by a predetermined distance;

The locking member 4 is held so as to be relatively movable in the axial direction with respect to the housing 31 in consideration of ease of insertion into the housing 31.
[0028]
As shown in FIGS. 4 to 6, the confirmation member 5 includes a C-shaped part 51 that can be expanded by elastic deformation, and a pair of protrusions that are integrally protruded inward from both ends of the C-shaped part 51. The locking projections 52 and 52 and the C-shaped portion 51 are integrally extended radially outward from the center in the circumferential direction, and when the confirmation member 5 is pulled out from the housing 31, fingers and the like are hooked to pull out And a ring-shaped handle portion 53 on which the C acts, and the C-shaped portion 51, the locking projection 52, and the handle portion 53 are integrally formed.
[0029]
And this confirmation member 5 inserts the latching protrusion parts 52 and 52 of the both ends of the C-shaped part 51 from the window parts 35 and 35 by expanding the diameter of the C-shaped part 51, and FIG. As shown, the housing 31 can be mounted. The inner peripheral surface shape of the C-shaped portion 51 corresponds to the outer peripheral surface shape of the large-diameter portion 31 a of the housing 31, and the inside of the C-shaped portion 51 is in a state where the confirmation member 5 is externally held by the housing 31. The peripheral surface is in close contact with the outer peripheral surface of the large-diameter portion 31a in a pressure contact state (described later). As is clear from FIG. 4, the confirmation member 5 has a center line passing through the center of the C-shaped portion 51 in the circumferential direction and the center between the locking projections 52 and 52 (BB in FIG. 4). Line)).
[0030]
Each of the locking protrusions 52, 52 is locked with the circumferential end 35 a of the window 35 before the male member 1 is coupled to the female member 3, so that the confirmation member 5 is perpendicular to the housing 31. The first locking portions 52a and 52a for restricting the drawing in the second symmetry axis Q direction in FIG. 2 (hereinafter the same), and the male member 1 in a state before the male member 1 is coupled to the female member 3. The tip which is located in the locus of the ring-shaped protrusion 1a at the time of insertion and is pressed by the ring-shaped protrusion 1a when the insertion of the male member 1 is completed and moves radially outward to expand the diameter of the C-shaped part 51 When the insertion of the male member 1 is completed, the contact member 52b, 52b is engaged with the circumferential edge 35b of the window 35, and the confirmation member 5 is moved perpendicularly from the housing 31 by the elastic return force of the C-shaped part 51. The confirmation member 5 is restricted after the male member 1 is completely inserted. In order to further expand the diameter of the C-shaped portion 51 through sliding contact with the circumferential edge 35b of the window portion 35 when being pulled out from the housing 31 in the direction perpendicular to the axis, the housing 31 is inclined toward the substantially centripetal direction. It has the inclination 2nd latching | locking part 52c, 52c extended, respectively.
[0031]
In the state in which the confirmation member 5 is externally held on the housing 31, the locking projection 52 is positioned at a position deeper in the axial direction of the housing 31 than the locking end 43 b of the claw 43. The part 35 is inserted into the housing 31. Further, in this embodiment, the tip contact portion 52b of each locking projection 52 is in a state before the confirmation member 5 is externally held by the housing 31 and the male member 1 is coupled to the female member 3, The male member 1 is inserted into the housing 31 up to a position where it can slidably contact the outer peripheral surface of the distal end portion 1b of the male member 1 to be inserted.
[0032]
Here, in this embodiment, the base end (the locking projection 52 and the C-shaped portion 51 and the boundary) of each locking projection 52 on the C-shaped portion 51 side (the upper side in FIGS. 4 and 6). A concave notch portion 54 (see FIG. 6) is provided, and a boundary portion between the notch portion 54 and the inclined second locking portion 52c is a first locking portion 52a. Further, the distance between the straight line connecting the circumferential end portions 35a of the window portions 35 and the outer surface of the flat portion 31e of the housing 31 is the C shape and the straight line connecting the first locking portions 52a and 52a. The dimensions of the C-shaped part 51, the housing 31 and the like are set so as to be slightly larger than the distance from the inner surface of the flat part of the part 51. With these configurations, the confirmation member 5 is externally held in the housing 31, that is, each first engagement portion 52 a of each engagement protrusion 52 of the confirmation member 5 is engaged with the circumferential end portion 35 a of the window portion 35. In this state, the C-shaped portion 51 of the confirmation member 5 is slightly elastically deformed, and this elastic force causes each first locking portion 52a to be substantially perpendicular to each circumferential end portion 35a of each window portion 35. It acts as a force to press. As a result, the side wall of the large-diameter portion 31a of the housing 31 on which the confirmation member 5 is mounted, that is, the C-shape, between each first locking portion 52a of the confirmation member 5 and the inner surface of the C-shaped portion 51. The side wall of the large-diameter portion 31a in which the inner surface of the portion 51 is in close contact with the pressure contact state is sandwiched in the direction perpendicular to the axis. As a result, the confirmation member 5 is firmly and securely held by the housing 31, the floating of the confirmation member 5 with respect to the housing 31 is prevented, and the confirmation member 5 is easily pulled out even if the confirmation member 5 is pulled out of the housing 31. You can't do that.
[0033]
It is an essential requirement of the present invention that the cutout portion 54 is formed and that the C-shaped portion 51 is elastically deformed slightly while the confirmation member 5 is externally held on the housing 31. Absent. However, when the dimension design is performed so that the C-shaped portion 51 is slightly elastically deformed in a state in which the confirmation member 5 is externally held on the housing 31, it is preferable to form the notched portion 54. If the notched portion 54 is not formed, the elastic restoring force of the C-shaped portion 51 is C-shaped through the engaging portion between the first engaging portion 52a and the circumferential end portion 35a of the window portion 35. This is because the confirmation member 5 is easily detached from the housing 31 because the shape portion 51 acts in the direction of expanding the diameter.
[0034]
In the present embodiment, both side surfaces on the distal end side of the respective locking projections 52 are tapered surfaces 55 and 55 whose intervals are narrowed toward the distal end. For this reason, when the male member 1 is inserted, the ring-shaped protrusion 1a is slidably contacted and guided to the taper surface 55 so that it easily enters the tip contact portion 52b. It is easy to move 52b outward in the radial direction.
[0035]
In this connector, in a state before the male member 1 is coupled to the female member 3, the confirmation member 5 is externally held on the outer peripheral surface of the housing 31 from the direction perpendicular to the axis, as shown in FIGS. At this time, each locking projection 52 of the confirmation member 5 is located in the housing 31 from each window 35 at a position on the rear side in the axial direction of the housing 31 relative to the locking end 43 b of each claw 43 of the locking member 4. The first locking portions 52a of the locking projections 52 are locked with the circumferential end portions 35a of the window portions 35, respectively. As described above, the first locking portion 52a of the locking projection 52 is locked with the circumferential end portion 35a of the window portion 35, so that the confirmation member 5 is reliably pulled out from the housing 31 in the direction perpendicular to the axis. In this state, even if the confirmation member 5 is pulled out from the housing 31 in the direction perpendicular to the axis, it cannot be pulled out. Further, in this state, the tip contact portion 52b of each locking projection 52 is located within the locus of the ring-shaped projection 1a when the male member 1 is inserted.
[0036]
When the insertion end 1 c of the male member 1 is inserted into the housing 31 of the female member 3 from the insertion opening end 31 d, the ring-shaped protrusion 1 a of the male member 1 is inclined by the claw portions 43 of the locking member 4. By pressing and slidingly contacting the inner surface 43 a, each claw portion 43 is pushed outward in the radial direction against its elasticity and passes through each claw portion 43. Thereby, each claw part 43 is elastically restored inward in the radial direction, and the locking end part 43b of each claw part 43 and the ring-shaped protrusion 1a are locked, and the male member 1 and the female member 3 are engaged. A coupled state is established via the stop member 4.
[0037]
When the insertion of the male member 1 is completed, as shown in FIG. 9 and FIG. 10, each tip contact portion 52b of each locking projection 52 located in the locus of the ring-shaped protrusion 1a is ring-shaped. The protrusions 1a are pressed to move outward in the radial direction, whereby the C-shaped portion 51 is expanded in diameter. When the diameter of the C-shaped portion 51 of the confirmation member 5 is increased in this way, each inclined second locking portion 52c of each locking projection 52 contacts the circumferential edge 35b of each window 35 of the housing 31. And locked. As described above, the inclined second locking portion 52 c of the locking projection 52 is locked to the circumferential edge 35 b of the window portion 35, whereby the confirmation member 5 is moved to the housing 31 by the elastic return force of the C-shaped portion 51. It is possible to reliably regulate the deviation from the direction perpendicular to the axis.
[0038]
In this state, if the confirmation member 5 is to be pulled out from the housing 31 in the direction perpendicular to the axis, the inclined second locking portions 52c of the locking projections 52 and the circumferential edges 35b of the window portions 35 are formed. Since the diameter of the C-shaped portion 51 is further expanded through the sliding contact, the confirmation member 5 can be easily pulled out from the housing 31 in the direction perpendicular to the axis. Thereby, the coupling | bonding of the male member 1 and the female member 3 can be confirmed.
[0039]
As described above, in the connector according to the present embodiment, after the male member 1 is coupled to the female member 3, the confirmation member 5 does not jump out of the housing 31 due to its elastic return force. For this reason, the operation | work which collects the confirmation member 5 which fell from the housing 31 after the coupling | bonding becomes unnecessary.
