Waterproof insulating engine wire harness assembly

The invention relates to the technical field of wire harnesses, in particular to a waterproof insulation engine wire harness assembly which comprises a wire harness body, a corrugated pipe body is arranged on the outer surface of the wire harness body, a first upper fastening ring is arranged on the upper surface of the corrugated pipe body, and an insulation block is fixedly connected to the back face of the first upper fastening ring. One end, far away from the first upper fastening ring, of the insulating block is fixedly connected with a second upper fastening ring; and the connecting shell is mounted on the outer surface of the corrugated pipe body. The mounting rod is mounted in the mounting groove, meanwhile, the arc-shaped pressing plate can be compressed through the spring body and the telescopic rod, meanwhile, deformation of the spring body can be limited through the telescopic rod, it is ensured that the position of the spring body is inconvenient, and therefore the whole arc-shaped pressing plate
