Embodiment

[0022] Such as Figure 1-3 As shown, a wear-resistant thin-walled polyvinyl chloride insulated automobile wire includes a joint 6 installed at the end of the wire, and two adjacent wires are electrically connected through the insertion of the two joints 6. As for the protection structure for protecting the joint 6, the protection structure includes two sliding rings 3 which are respectively fitted on two adjacent electric wires and can slide freely, and the protection cover 1 is set on the sliding ring 3, The opposite ends of the two protective covers 1 are jointly fitted with a rotating ring 8, and the axial ends of the rotating ring 8 are respectively provided with a first threaded hole 7 and a second threaded hole 9 with opposite screw directions. The opposite ends of the cover 1 are threaded on the first threaded hole 7 and the second threaded hole 9 respectively, and when the rotating ring 8 rotates, the opposite ends of the two protective covers 1 are opposed to each oth...

Abstract

The invention discloses a wear-resistant thin-wall polyvinyl chloride insulated automobile wire and belongs to the technical field of wires. The wear-resistant thin-wall polyvinyl chloride insulated automobile wire comprises a wire, a joint and a protection structure; the wire comprises a wear-resistant layer, an insulating layer and a plurality of wire cores sequentially distributed from outside to inside, a gap is formed between the wear-resistant layer and the insulating layer, and a plurality of buffer structures for connecting the wear-resistant layer and the insulating layer are arranged in the gap. By arranging the wear-resistant layer, the surface of the insulating layer can be prevented from being worn after the wire is installed in an automobile body, meanwhile, the gap is formed between the wear-resistant layer and the insulating layer, and the buffer structures are arranged in the gap, so that when the wire is extruded, extrusion external force is buffered through the buffer structures, damage to the insulating layer and the wire cores caused by the extrusion force can be reduced; two protective covers are adopted; the two protective covers can protect the joint of two wires through rotation of a rotating ring, and the phenomena of electric leakage of the wires due to the damage of the joint by external force is avoided.

Description

technical field [0001] The invention relates to the technical field of wires, in particular to a wear-resistant thin-wall polyvinyl chloride insulated automobile wire. Background technique [0002] The automobile wiring harness is the main body of the automobile circuit network, and there is no automobile circuit without the wiring harness. The wire harness refers to the contact terminal (connector) punched from copper and the wire and cable after crimping, and then plastic insulator or metal shell on the outside, and then bundled with wire harness to form a connected circuit component. The wiring harness industry chain includes wire and cable, connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computers and communication equipment, various electronic instruments, etc. The body wiring harness connects the entire body . With the advancem...
