Document Type and Number:
WIPO Patent Application WO/2022/064861
Kind Code:
A1
Abstract:
The present invention prevents rattling between a die-cast case and a synthetic resin housing and penetration of water into a fitted portion between the die-cast case and the housing. A waterproof connector (A) comprises: a die-cast case (10) having a box-shaped case body (11) and a cylindrical part (12) protruding forward from the case body (11), the die-cast case (10) being a metal cast; and a synthetic resin housing (31) accommodated in the die-cast case (10). The inner circumferential surface of the cylindrical part (12) has formed thereon a sealing surface (25) that makes contact with a sealing member (53) of a mating connector (B). The sealing surface (25) is a non-processed surface that has not been polished after casting. A holding surface (26) for holding the housing (31) in a contacted state is formed to the rear of the sealing surface (25) in the die-cast case (10). The holding surface (26) is a processed surface that has been polished to have a smaller surface roughness than the sealing surface (25).
