PROBLEM TO BE SOLVED: To provide a conversion adaptor with a simple constitution capable of connecting a rigid male connector having a female screw for locking and various kinds of male connectors having different sizes and shapes.SOLUTION: A conversion adaptor 1 includes a connection tube 12 for connecting a first male connector 3 and a second male connector 5. The connection tube 12 includes a part 15 of one end side having a first conical inner surface 13 and a male screw 14 respectively corresponding to a first conical outer surface 6 and a female screw 8 of the first male connector, and a part 17 of the other end side having a second conical inner surface 16 corresponding to a second conical outer surface 10 of the second male connector 5. The connection tube 12 is entirely made of an identical resin material, and the part 17 of the other end side is thinner than the part 15 of one end side so as to have plasticity to be compatible with the various kinds of the second male connectors.COPYRIGHT: (C)2014,JPO&INPIT【課題】ロック用の雌ネジを有する硬質の雄コネクタとサイズや形状が異なる各種の雄コネクタとを連結できる簡便な構成の変換アダプタを提供する。【解決手段】変換アダプタ1は、第1雄コネクタ3と第2雄コネクタ5とを連結する連結管12を備える。連結管12は、第1雄コネクタの第1円錐外面6及び雌ネジ8にそれぞれ対応する第1円錐内面13及び雄ネジ14を有する一端側部分15と、第2雄コネクタ5の第2円錐外面10に対応する第2円錐内面16を有する他端側部分17とを備える。連結管12は、全体が同一の樹脂材料で形成され、他端側部分17が、各種の第2雄コネクタに対応できる柔軟性を有するように、一端側部分15よりも薄い。【選択図】図4
