Insulated wire, and wire harness

Abstract

Provided are an insulated wire comprising an insulating sheath that is formed from a resin composition with high wear resistance, and a wire harness comprising this sort of insulated wire. Provided isan insulated wire 10 having a wire conductor 12 and an insulating sheath 14 that covers the periphery of the wire conductor 12, wherein the insulating sheath 14 is formed from a resin composition that has a thermoplastic polyester elastomer as a primary component. Also provided is a wire harness including this sort of insulated wire 10. The thickness of the insulating sheath 14 is preferably lessthan 0.7mm.

Description

technical field [0001] The present invention relates to an insulated wire and a wire harness. More specifically, it relates to an insulated wire that can be suitably used for electrical connection of automobiles and the like, and a wire harness including such an insulated wire. Background technique [0002] Insulated electric wires are generally required to have high flexibility in order to ensure wiring properties. Especially in the case of insulated wires used for electrical connections in automobiles, wiring in a limited space or wiring in complicated paths has increased as automobiles have become more functional and high-performance in recent years. Increased demands on flexibility. [0003] As a means of improving the flexibility of insulated wires, a method of reducing the thickness of the insulating coating layer may be adopted. Thinning the insulating coating also contributes to space saving by reducing the diameter of the insulated wire. However, if the insulatin...

Problems solved by technology

However, the effect of improving the wear resistance due to the addition of these resin components to the PVC resin is limited, and even if the wear resistance is improved, it is difficult to sufficiently ensure the flexibility of the insulating coating layer, and it is difficult to achieve both. Softness and abrasion resistance
