[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By fixing a plurality of fixed rings and a plurality of corrugated tubes at intervals on the outside of the first insulating layer, and filling the inner side of the corrugated tube between two adjacent fixed rings with rat-proof powder, the wire harness body inside can be effectively protected against rats, making it difficult for rats to bite the trailer wire harness, thereby improving the rat-proof effect of the trailer wire harness.

[0013] 2. An anti-tear layer, a metal mesh layer and a first insulating layer are sequentially arranged on the outside of the wiring harness body to enhance the overall anti-bite performance of the trailer wiring harness, so that the wiring harness body is not easily bitten. A number of reinforcing ribs distributed in a circular array are arranged inside the first insulating layer, which further enhances the tensile performance of the trailer wiring harness and further improves the rat-proof effect of the trailer wiring harness.
