AI Technical Summary

Technical Problem

Existing electromagnetic shielding structures for cables in vehicles require additional parts like crimping rings, which increase complexity and risk protrusions that hinder cable routing, and often reduce the inner diameter, creating gaps and installation challenges.

Method used

An electromagnetic shielding structure where the electromagnetic shielding tube and braided wire are connected by brazing or soldering, eliminating the need for crimping rings and ensuring a consistent inner diameter, allowing for space-saving and efficient wiring.

Benefits of technology

The solution provides improved connection workability and subsequent wiring workability by eliminating protrusions and maintaining a uniform inner diameter, facilitating easier installation and reduced interference in vehicles.

Abstract

To provide an electromagnetic shield structure which has good connection workability, and also has excellent wiring workability thereafter.SOLUTION: In an electromagnetic shield pipe 1, a resin inner layer 3 is formed on the innermost layer, a metal layer 5 is formed on the outer periphery of the inner layer 3, and a resin outer layer 7 is formed on the outer periphery of the metal layer 5. In the electromagnetic shield pipe 1, the outer layer 7 is removed from the end by a predetermined length. Specifically, the metal layer 5 is exposed only in a predetermined range to the end of the electromagnetic shield pipe 1. The end of the electromagnetic shield pipe 1 is inserted to the end of a braided wire 13. A brazing material 11 arranged in an overlapping part of the electromagnetic shield pipe 1 and the braided wire 13 is melted, and the electromagnetic shield pipe 1 and the braided wire 13 are joined to each other by brazing.SELECTED DRAWING: Figure 4
