Problems solved by technology

However, when cables are used on the body of an automobile, etc., there is a problem that the cables move relative to the resin molded part under conditions where the cables are subjected to vibration, so that the sealing material is peeled off from the joint portion of the cable and the resin molded part, resulting in a decrease in waterproof performance

Abstract

A connector (10) comprises a primary resin-molded member (20) integrally covering both a terminal (18) and a covering material (14). A first sealing material (24) is disposed at the first joining portion (28) between the primary resin-molded member (20) and the covering material (14) so as to seal the first joining portion (28). The first sealing material (24) is integrally covered together with the primary resin-molded member (20) by a secondary resin-molded member (22). The peeling of the first sealing material (24) from the first joining portion (28) is suppressed by the secondary resin-molded member (22), whereby the durability of the waterproof structure can be improved.

Description

technical field [0001] The present invention relates to a connector provided at the end of a cable, and in particular to a waterproof structure of the connector. Background technique [0002] A connector is known that is provided at the end of a cable including a conductor and a covering material covering the conductor, and electrically connects the cable to another cable or electric equipment. A connector has a terminal to be joined to a conductor protruding and exposed from a covering material, and the terminal is joined to a terminal provided on an electrical device or other cables to be connected to achieve electrical connection. A connector is known in which a terminal and a portion of a covering material adjacent to the terminal is integrally covered with a resin molded member for the purpose of waterproofing, dustproofing, or the like. [0003] Japanese Patent Application Laid-Open No. 8-138794 discloses a technique of waterproofing a resin molded member accommodatin...
