Wiring harness waterproof connecting structure

Abstract

The invention provides a wiring harness waterproof connecting structure. A PCB (Printed Circuit Board) is adopted as an adaption bridge, a sheath is adopted to assemble and fix the shape, and the structure is finally completely sealed by using a pouring sealing type waterproof adhesive, so that moisture cannot pass an adaption part from a core line, a waterproof effect is achieved, and the servicelife of an external connecting part is ensured. The structure comprises a wiring harness and core lines, wherein the core lines correspond to external connecting parts; corresponding connecting linesof the wiring harness in a length direction are exposed on the overall length end surface of the wiring harness; the exposed ends of the corresponding lines are connected with the connecting ends ofthe core lines through the PCB; the PCB is sealed by the waterproof adhesive as a whole; the waterproof adhesive extends to the overall outer ring surface of the wiring harness and the outer ring surface of each core line.

Description

technical field [0001] The invention relates to the technical field of wiring harness waterproofing, in particular to a wiring harness waterproof transfer structure. Background technique [0002] In order to improve people's quality of life, automotive wiring harnesses are constantly striving to improve the waterproof level requirements to ensure the service life and quality of automotive electronics. The assembly parts of the wiring harnesses for external connection parts such as automotive cameras involve waterproof performance requirements. Existing The advanced waterproof transfer structure cannot block water vapor from entering the interior of the parts that need to be connected, so that the service life of the connected parts is relatively short. Contents of the invention [0003] In view of the above problems, the present invention provides a wiring harness waterproof transfer structure, which uses a PCB board as a transfer bridge, assembles and fixes the appearance...
