Abstract

A connector 1 configured to be attached to a device 2 is provided with: an annular housing 11 configured to be attached to the device 2 in such a position as to annularly rise from the device 2; an annular seal member 22 that seals a space between an end surface of the housing 11 facing the device 2 and the device 2 in a watertight manner; and a water-preventing wall 25 that extends from the housing 11 toward the device 2 outside the seal member 22, and that protects the seal member 22 from high-pressure water externally sprayed toward the housing 11.

Claims

1. A connector that attaches to a device, the connector comprising:

an annular housing that attaches to the device in such a position as to annularly rise from the device;

an annular seal member that seals a space between an end surface of the housing facing the device and the device in a watertight manner; and

a water-preventing wall that extends from the housing toward the device outside the seal member, and that protects the seal member from water externally sprayed toward the housing,

wherein the housing is made of resin,

the connector further comprising;

an electric wire integrally molded in the housing so as to penetrate through a wall of the housing;

a metal plate that is fixed to the device with the housing being all around pressed toward the device;

a rib provided along an outer peripheral portion of the metal plate, the outer peripheral portion not overlapping the electric wire as viewed in a direction perpendicular to a plate surface of the metal plate,

wherein;

the metal plate does not have a rib in an outer peripheral portion overlapping the electric wire as viewed in the direction perpendicular to the plate surface; and

the water-preventing wall is provided at least in a section in which the electric wire is integrally molded in the circumferential direction of the housing.

2. The connector according to claim 1, wherein

the device includes a seal press-contacted surface that the seal member press-contacts, and an outer wall surface continuous with the seal press-contacted surface, and

the water-preventing wall is provided at a position outside the outer wall surface with the housing attached to the device, and shields, as viewed in a direction perpendicular to a central axis of the seal member, a gap between the housing and the device, and an edge portion of the outer wall surface on the seal press-contacted surface side.
