Abstract

Disclosed herein are methods and apparatus for providing as strain relief (18) for use in the assembly of an electrical connector (14) on an end of an electrical conductor (16) having at least an outer braided portion (24), which may be surrounded by an insulating cover. The methods and apparatus disclosed herein provide a low cost approach for installation using minimal tooling, while providing a precise and robust relief that ensures electrical performance.

Description

[0001] This application claims priority to Provisional Patent Application No. 60 / 379,353, filed on May 10, 2002, under Title 35 of the United States Code, 119(e). technical field [0002] The present invention relates to electrical connectors, and more particularly to strain relief devices for use in electrical connectors and conductor assemblies. Background technique [0003] In some conventional electrical connectors and cable assemblies, the most common method for electrically connecting a cable braid to a metal housing is to crimp a metal ferrule over the braid and squeeze slightly when closing the housing. Press the hoop. Usually, crimping is done by hand and therefore imprecise. [0004] This type of system creates a situation where the above-mentioned pair of crimped wires will damage the insulator when too much crimping force is applied. For example, the deterioration of electrical properties is caused by the application of excessive force during crimping. There a...
