Abstract
Description
分岐コネクタ1は、第1分割ハウジング10と、第2分割ハウジング20と、第1分割ハウジング10と第2分割ハウジング20とを接続する接続部30と、を有している。第1分割ハウジング10、第2分割ハウジング20、及び接続部30は、絶縁性の合成樹脂材料により構成した一体成形品からなる。接続部30には折曲部32が形成されており、この折曲部32を延ばす又は折り曲げることにより、第1分割ハウジング10及び第2分割ハウジング20(一対の分割ハウジング)は、両者が離間した「開状態」と両者が接触した「閉状態」との間で互いに開閉可能となっている。
第1分割ハウジング10の外周側第1対向面16と第2分割ハウジング20の外周側第2対向面27とは、止水性を維持できる程度に接面することはないため、別途防水の対策が必要となる。本実施形態の分岐コネクタ1は、第1分割ハウジング10の外周側第1対向面16と第2分割ハウジング20の外周側第2対向面27との間の微小な隙間から水が浸入しようとしたときの防水構造を具備している。以下では、図11、図12を参照して、この防水構造について説明する。
第1分割ハウジング10と第2分割ハウジング20とを閉状態にして第1防水用ゲル70と第2防水用ゲル80とを圧縮状態で支持したときであっても、第1防水用ゲル70及び第2防水用ゲル80が、ゲル支持空間Y及びゲル逃がし空間Zを利用して、第1分割ハウジング10と第2分割ハウジング20との開方向(上下方向)と直交する前後左右方向に逃げることができる。このため、分岐コネクタ1は、第1分割ハウジング10と第2分割ハウジング20との開方向(上下方向)への反発力を抑制して閉状態を安定的に維持することができる。
図12に示すように、本実施形態の分岐コネクタ1は、第1分割ハウジング10と第2分割ハウジング20とが、中央支持空間Xに支持された中継コンタクト40の第1ケーブル圧接片42及び第2ケーブル圧接片43の直ぐ外側に位置して互いに近付くように延びる開き抑制壁14aと開き抑制壁25aとを有している。これにより、例えば、中継コンタクト40に接続する第1ケーブル50と第2ケーブル60とが太径であるために第1ケーブル圧接片42及び第2ケーブル圧接片43に外側(第1ケーブル圧接片42にとっては左側で第2ケーブル圧接片43にとっては右側)に開くような力が加わった場合であっても、この力を開き抑制壁14aと開き抑制壁25aとで受け止めて、第1ケーブル圧接片42と第2ケーブル圧接片43とが外側に開くのを効果的に防止することができる。
