Embodiment 1

[0018] A coated yarn for harness protection, having a structure such as figure 1 As shown, it consists of a wire core 1 and a coating 2 covering the wire core 1 .

[0019] The wire core 1 is composed of a large number of core wires 3; the core wire 3 is polyester wire; the coating 2 is polyvinyl chloride; the number of the core wires is not less than 10; the diameter of the wire core 1 is is 0.7mm; the thickness of the coating 2 is 0.2mm.

[0020] The coated yarn for wire harness protection in this embodiment is woven into a braided wire layer covering the outside of the wire. The braided wire layer has a staggered structure, which is not affected by the external temperature and has a wide range of applications; it has a compact structure, a small footprint, and a long service life. Long; the material is wear-resistant, high and low temperature resistant. The braided wire layer has tiny gaps, so it has good heat dissipation, soft and waterproof, and will not retain particula...

Abstract

The invention discloses a coated yarn for harness protection, which is used for being woven into a woven yarn layer wrapping a wire, and the woven yarn layer is of an interleaved structure, is not affected by outside temperature, and has a wide application range; the structure is compact, the occupied area is small, and the service life is long; the material can resist wear and high and low temperatures. Because the woven yarn layer is provided with tiny gaps, the woven yarn layer has good heat dispersion, and is soft and waterproof, particulate matter cannot be retained in special operation, and thereby the service life of the wire is long; during installation, an adhesive tape is needed for binding, other accessories are not needed, and therefore installation is convenient; nylon filaments or terylene filaments are chosen as core filaments, so that the tensile strength of the coated yarn is enhanced greatly, while coating made of high-performance material such as polyvinyl chloride, polyvinylidene fluoride or polyester rubber endows the coated yarn with the advantages of high temperature resistance, corrosion resistance and ultraviolet resistance.

Description

technical field [0001] The present invention relates to a coated yarn for harness protection. Background technique [0002] The plastic or resin layer wrapped in the outer layer of the existing wires and wire harnesses is a closed spiral corrugated structure, which has poor air permeability, large footprint, high or low temperature resistance, and poor chemical resistance. The substance sticks and is inconvenient to use. [0003] The use of high-quality PVC engineering yarn is used to weave the braided wire layer to cover the wire. The braided wire layer is a staggered structure, which is not affected by the external temperature and has a wide range of applications; it has a compact structure, a small footprint, and a long service life; the material is wear-resistant. , High and low temperature resistance. The braided wire layer has tiny gaps, so it has good heat dissipation, is soft and waterproof, and will not retain particulate matter in special operations, and the wire...
