Abstract
Description
本発明の第1実施形態に係るコネクタを図1~図6に従って説明する。
図1に示すように、本実施形態のコネクタ10は、例えば、車両のエアダクトホースのIN.OUT用のジョイントコネクタとして使用されている。また、コネクタ10は第1管部材12と第2管部材14とを備えている。第1管部材12の一方の端部12Aはユニット15に連結されており、第2管部材14の一方の端部14Aは冷却用の送風装置に連結されたダクト16に連結されている。
次に、本実施形態に係るコネクタの作用と効果について説明する。
図1及び図5に示すように、コネクタ10の第1管部材12と第2管部材14とが連結され、リング部材40がロック位置にある場合には、図5に示すように、第2管部材14に設けたストッパー52の爪部54の先端部54Aが、第1管部材12の被係合部21の係合面21Cに係合している。また、ストッパー52のカム部56の内周側面56Aがカム挿入部40Aの内周面側に設けられた凸部60に当接しており、ストッパー52の係合位置(図5の位置)から非係合位置(図6の位置)へ向かう係合解除方向(図5の矢印C方向)への回転が防止されている。
次に、本発明の第2実施形態に係るコネクタを図7~図9に従って説明する。
なお、第1実施形態と同一部材に付いては、同一符号を付してその説明を省略する。
次に、本発明の第3実施形態に係るコネクタを図10~図13に従って説明する。
なお、第1時実施形態と同一部材に付いては、同一符号を付してその説明を省略する。
次に、本発明の第4実施形態に係るコネクタを図14~図17に従って説明する。
なお、第1実施形態と同一部材に付いては、同一符号を付してその説明を省略する。
次に、本発明の第5実施形態に係るコネクタを図18~図21に従って説明する。
なお、第1実施形態と同一部材に付いては、同一符号を付してその説明を省略する。
以上に於いては、本発明を特定の実施形態について詳細に説明したが、本発明は上記実施形態に限定されるものではなく、本発明の範囲内にて他の種々の実施形態が可能であることは当業者にとって明らかである。例えば、上記各実施形態では、第2管部材14のストッパー52と、第1管部材12の被係合部21とを周方向に沿って180°離間して2箇所に設けたが、コネクタ10が大口径の場合には、ストッパー52と被係合部21とを3箇所以上設けてもよく、この場合にも、リング部材40の操作によって、3箇所以上のストッパー52を同時に移動することができる。
