Abstract
【解決手段】 コネクターAを、コネクター本体10、シール部材20、弁体30で構成し、コネクター本体10を、チャンバー部11と、チャンバー部11からそれぞれ異なる方向に延びる下流分岐管12、上部分岐管13、上流分岐管14で構成した。シール部材20は、上部分岐管13の開口部に固定された固定片22と、固定片22に連結され、上部分岐管13を閉塞するシール部材本体21とで構成した。そして、上部分岐管13の開口部から内部に雄ルアー部28を挿入してシール部材本体21を上部分岐管13の内部側に押し込むことにより、チャンバー部11と雄ルアー部28とを連通できるようにした。また、上部分岐管13内にシール部材本体21をガイドするガイド部17を設けた。

Description
Claims (4)
- チャンバー部と、前記チャンバー部からそれぞれ異なる方向に延びる複数の分岐管とからなるコネクター本体と、前記複数の分岐管のうちの所定の分岐管に取り付けられて前記所定の分岐管を開閉するシール部材とを備えたコネクターであって、
前記シール部材を、前記所定の分岐管の開口部側の所定部分に固定された固定片と、前記固定片に連結され、前記所定の分岐管の開口部を閉塞するとともに、前記所定の分岐管の開口部から内部に向って接続管を挿入することにより前記所定の分岐管の内部側に押し込まれて、前記チャンバー部内と前記接続管内とを連通させるシール部材本体とで構成したことを特徴とするコネクター。 - 前記シール部材本体が前記所定の分岐管の内部側に押し込まれて、前記チャンバー部内と前記接続管内とを連通させるときに、前記シール部材本体が所定の軌道に沿って移動できるようにガイドするガイド部を前記所定の分岐管内における下部側部分に設けた請求項1に記載のコネクター。
- 前記所定の分岐管の開口縁部に切欠き部を形成し、前記固定片を前記開口部の外部側に突出させた状態で、前記切欠き部に前記シール部材本体と前記固定片との連結部を係合させ、その状態の開口部の外周側に蓋部材を取り付けることにより前記固定片を前記所定の分岐管に固定した請求項1または2に記載のコネクター。
- 前記チャンバー部内で移動することにより前記複数の分岐管のうちの任意の分岐管を連通させる弁体を前記チャンバー部内に設置した請求項1ないし3のうちのいずれか一つに記載のコネクター。
