Waterproof Connector Connection Structure

摘要

A first connector is fluid-tightly fitted with a second connector through an opening of a mounting wall. The first connector includes a cylindrical spacer fitted into the opening, and a housing having a support part and a housing body. The support part is mounted to a first surface of the mounting wall while being able to be displaced along a plane perpendicular to a connector fitting direction of the first and second connectors. The housing body has a leading end which is inserted in the opening with a clearance. A first ring-shaped seal member is interposed between the opening and the spacer, a second ring-shaped seal member is interposed between the spacer and the support part in the connector fitting direction, and a third ring-shaped seal member is interposed between the second connector and the leading end.

主权项

1. A waterproof connector connection structure comprising:
a first connector configured to be mounted to a first surface of a mounting wall having an opening while being inserted into the opening; and a second connector configured to be supported at a second surface of the mounting wall which is opposite to the first surface, wherein the first connector is fluid-tightly fitted with the second connector through the opening of the mounting wall; wherein the first connector includes:
a cylindrical spacer which is fitted into the opening of the mounting wall; anda housing having a support part and a housing body; wherein the support part is mounted to the first surface of the mounting wall while being able to be displaced along a plane perpendicular to a connector fitting direction of the first and second connectors; wherein the housing body is provided to so as to suspend from the support part, and a leading end of the housing body is inserted in the opening with a clearance between an inner periphery of the spacer and an outer periphery of the housing; wherein a first ring-shaped seal member is interposed between an inner periphery of the opening and an outer periphery of the spacer; wherein a second ring-shaped seal member is interposed between the spacer and the support part in the connector fitting direction; and wherein a third ring-shaped seal member is interposed between the second connector and the leading end.
