[0003] In the prior art, such as the application with application number CN201820614982.7, the title is: A waterproof plug-in harness, which includes a plug, a harness and a sheath housing. One end of the plug is a plug interface, and the harness passes through the plug and connects to the plug interface. The other end of the plug is provided with a tubular connecting part, and a fixing part is provided on the outer wall of the connecting part. The sheath housing is an injection molded part, which is disposed on the periphery of the connecting part and the end of the harness by injection molding to connect the plug and the harness.

[0004] However, in the wire harnesses mentioned in the existing technology, the connectors and sheath connecting posts are injection molded during the wire harness production process. Over time, these connections are prone to falling off, affecting the overall waterproof performance of the wire harness. Therefore, it is necessary to design a waterproof plug-in wire harness.
