Abstract

A cable retainer functions both as a mechanical retainer and as an electrical connector for cables having shields requiring connection to ground potential. It has been the practice to use a separate connecting wire or to form the cable shield into a pigtail to ground the cable shield.

Cable Shield Termination

A cable retainer functions both as a mechanical retainer and as an electrical connector for cables having shields requiring connection to ground potential. It has been the practice to use a separate connecting wire or to form the cable shield into a pigtail to ground the cable shield.

The separate wire or the step of forming the cable shield into a pigtail has been eliminated, by using a cable retainer as the connector for the ground connection. Cable retainer 10, in the drawing, is either made of electrical conducting material or of a nonconductor plated with an electrical conductor. Normally, it is less expensive to mold cable retainer 10 from plastic and then plate a conductive coating on the plastic.

Cable retainer 10 includes a body element 11 having outwardly projecting serrations 12 for establishing electrical contact with shield 21, which is folded back upon cable 20. Body 11 has a pair of spaced slots 13 and 14 for receiving tie wraps 26 which bind retainer 10 to cable 20. Body 11 also has longitudinal grooves 15 opening outwardly to facilitate attachment to metal bracket 30, to complete the mechanical retainment of cable 20 and the electrical ground connection from shield 21.
