Connector with a sealing ring having a bulge at its inner peripheral side of its main body

摘要

A connector has a housing (40) including a terminal mounting portion (41), a receptacle (55) and a mounting flange (61) between the terminal mounting portion (41) and the receptacle (55). A seal ring (150) is mounted on a surface of the mounting flange (61) to be held in contact with a mounting wall (20) for sealing between the mounting flange (61) and the mounting wall (20). The seal ring (150) includes a ring main body (151) surrounding the outer periphery of the terminal mounting portion (41) and fixing portions (160) for fixing the ring main body (151) to the mounting flange (61). Each fixing portion (160) includes a bulge (161) at an inner peripheral side of the ring main body (151). A lock (165) projects from the bulge (161) toward a side opposite to a sealing surface and engages a locking hole (67) in the housing (40).
