Automobile thin-wall thermoplastic insulation low-voltage cable

Abstract

The invention discloses an automobile thin-wall thermoplastic insulation low-voltage cable. The automobile thin-wall thermoplastic insulation low-voltage cable comprises a tin-coated copper conductive core, a polyvinyl chloride thermoplastic elastomer wrapping the tin-coated copper conductive core and a sheath layer wrapping the polyvinyl chloride thermoplastic elastomer. According to the invention, an insulation layer employs the polyvinyl chloride thermoplastic elastomer which has quite good insulation performance, enables the cable to have the advantages of deformation resistance, high elasticity, high weatherability and the like, is plasticized and formed at a high temperature and has a thickness meeting the requirement for the thickness of the cable. The sheath layer ensures that the thin-wall cable has quite good flame-retardant fireproof performance and quite higher mechanical performance.

Description

technical field [0001] The invention relates to the field of cables, in particular to a thin-walled thermoplastic insulated low-voltage cable for automobiles. Background technique [0002] As more and more electronic devices are installed in cars, more and more car wires are needed to provide power and control signals. Due to the increase of these electric wires, the binding wires used to bind the electric wires are becoming thicker and thicker, so the weight of the cables increases, the ease of assembly decreases, and the volume of these cables becomes difficult to accommodate in the space of the vehicle body. The new automotive wire standard issued by the ISO organization (International Organization for Standardization) specifies an ultra-thin-walled automotive wire, for a cross-sectional area of ​​1.5mm 2 The wall thickness of the insulation layer of automobile cables with specifications below and below does not exceed 0.2mm, and some automobile manufacturers even put ...
