Abstract
Abstract The invention provides a strain relief bushing which is utilized to grip a wire conductor passing through a panel member or the like, with the bushing inserted in an aperture in the panel or in a slot contained therein and firmly gripped by its edges to compress the wire conductor so that the bushing resists any tensile pull placed on the conductor. The bushing includes further provision for means for receiving an additional overlapping panel member.

Claim 5
Dependent Claim
48 words
The strain relief bushing and panel means of claim 5 wherein; a. termination of said groove means provides a space on said flange, and b. said space is substantially flat for forming a seating means for at least a part of said other portions of said panel means.
Claim 6
Dependent Claim
38 words
The strain relief bushing and panel means of claim 5 wherein: a. said flange means is tapered, b. said taper provides for ease in insertion of said strain relief bushing in said other portions of said panel means.
Claim 7
Dependent Claim
