Problems solved by technology

As a result, the braided shielded wire 352 generates heat, and the resistance value of the connecting portion between the power supply box and the shielded wire may increase.
In addition, as a result of the heating of the braided shielded wire, the covering layer 351 is subjected to high temperature, and microcracks may occur on the covering layer 351.

Abstract

To provide a shield wire excellent in bending property, shock resistant property, and heat resistant property, and to provide a box connected to the shield wire, a method of connecting the shield wire and the box, and a shield wire unit.The shield wire is composed of a wire body 20 formed by covering a conductor 17 made of single wire or stranded wire by an insulation body 15, and a shield member arranged at outer periphery of the wire body 20. The shield member is constituted of a cylinder 50 formed by successively arranging a braided shield 12 and an outer sleeve 22 around an inner sleeve 21, and a metal pipe 11 arranged so as to face the cylinder 50. The cylinder 50 is electrically connected to the metal pipe 11, and a pipe-shaped connection member 310 is fitted to a non-cylindrical side of the metal pipe 11. A connector member 500 having a flange part 502 is electrically connected to a non-metallic pipe side of the cylinder 50.

Description

technical field [0001] The present invention relates to shielded electric wires for supplying power to equipment, and more particularly to shielded electric wires for supplying power to various equipment in automobiles. Background technique [0002] The shielded electric wire has a braided shielded wire braided with copper wires, tinned copper wires, or the like having a wire diameter of several tens of μm to several hundreds of μm on the outside of the sheathed electric wire. By connecting both ends of the braided shielded wire to metal connectors and grounding the connectors, a protective effect against malfunction due to electromagnetic waves or the like can be obtained. [0003] In recent years, for automobiles, hybrid vehicles are gaining popularity, and the electrification of equipment is advancing rapidly. Therefore, in shielded wires used in various equipment of automobiles, etc., high voltage and high current are increasingly realized. In addition, with the popula...
