Waterproof structure of wire harness with connector

Abstract

A waterproof structure of a wire harness with a connector in which crimp terminals are housed and held in a plurality of cavities respectively in the connector, the crimp terminals being crimped to electric wire terminals of a plurality of electric wires included in the wire harness, includes a sheet material having a width covering both the connector and the electric wires from rear cavity openings, having waterproof property and elasticity, and having adhesive surfaces on one side. The sheet material is fixedly attached to a connector neck portion where the plurality of electric wires project outward from the rear cavity openings of the connector by tightly attaching the adhesive surfaces to each other from two sides having the connector therebetween, and thus the connector neck portion is covered by the sheet material.

Description

technical field [0001] The present invention relates to a waterproof structure of a wire harness with a connector in which a connector is provided at the end of a wire harness composed of a plurality of electric wires. Background technique [0002] Conventionally, a connector that accommodates and holds crimp terminals crimped to ends of a plurality of wires constituting the wire harness in a cavity inside is attached to the terminal portion of a wire harness used in an electrical system of an automobile. In addition, by connecting the above-mentioned connectors to counterpart connectors provided on various electrical components, power supply and distribution from the battery to the electrical components can be easily and reliably performed. Such a wire harness with a connector is described in, for example, Japanese Patent Application Laid-Open No. 62-188186 (Patent Document 1). [0003] In addition, recently, in order to reduce the weight of vehicles, it is considered to u...

Problems solved by technology

[0004] However, in such a conventional waterproof structure, although it is possible to reliably waterproof the fastened portion of the crimp terminal of each electric wire, it is necessary to perform waterproof processing for each electric wire, which complicates the manufacturing process and increases man-hours. , there is the problem of unavoidable cost increase

In addition, since the fastened portion of the crimp terminal of each electric wire becomes thick due to waterproofing or anti-corrosion agent, there is also a problem that the cavity of the connector to which these are mounted and the size of the entire connector cannot be avoided.

[0005] In addition, there are actual situations in which the waterproof standard required for the wiring harness with a connector is relatively low, such as the case where the wiring harness with a connector is arranged in the vehicle interior. The waterproof structure of the harness has not been proposed
