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.

Independent Claim 32 words
The strain relief bushing and panel means of claim 1 wherein: a. each of said opposed portions includes a shoulder means, and b. each of said shoulder means providing a decorative bezel.
Claim 2
Dependent Claim 19 words
The strain relief bushing and panel means of claim 2 wherein: a. each of said shoulder means is rectangular.
Claim 3
Dependent Claim 39 words
The strain relief bushing and panel means of claim 1 wherein: a. said opposed portions are capable of assuming a compressed abutting position, b. in said compressed position, said strain relief bushing includes an aperture of generally elliptical shape.
Claim 4
Dependent Claim 41 words
The strain relief bushing and panel means of claim 4 wherein: a. said strain relief bushing in compressed condition includes a flange means extending axially relative to said aperture, and b. said flange means includes said peripheral groove means disposed therein.
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 110 words
A strain relief bushing and panel means assembly including: a. a pair of opposed portions on said strain relief bushing, b. an integral hinge portion connecting said opposed portions, c. said opposed portions including peripheral groove means, d. a spacing means provided on one of said opposed portions, e. said spacing means positively locating a first panel means relative to the width of said peripheral groove means, said first panel means extending into said peripheral groove means, f. said groove means extending only partially around said pair of opposed portions, and g. a second panel means seating on said strain relief bushing in the area thereof having no groove means.
Claim 8
Dependent Claim 111 words
The combination of a strain relief bushing and a pair of overlapping panel means including: a. a first panel means having an aperture means, b. said strain relief bushing disposed in said aperture means, c. said strain relief bushing including groove means and spacer means, d. a second panel means disposed in at least a portion of said groove means and positioned therein by said spacer means. e. said strain relief bushing including shoulder means disposed outwardly of said groove means and contiguous to said second panel means, and f. one of said shoulder means including a vertical tapered portion for providing an angulated lead in for said second panel means.
Claim 9
Dependent Claim 103 words
The combination of a strain relief bushing and a pair of overlapping panel means including: a. a first panel means having an aperture means, b. said strain relief bushing disposed in said aperture means, c. said strain relief bushing including groove means and spacer means. d. a second panel means disposed in at least a portion of said groove means and positioned therein by said spacer means, e. said strain relief bushing including an aperture means, f. conductor means extending through said aperture means, and g. tapered rib means disposed adjacent said aperture means for providing a compressive force on said conductor means.
Claim 10
Dependent Claim 91 words
A strain relief bushing for use with panel means including: a. a pair of opposed portions, b. an integral hinge portion connecting said opposed portions, c. said opposed portions including peripheral groove means, d. said peripheral groove means having a narrower segment on one of said opposed portions than on the other of said opposed portions, said narrower segment being present solely on said one of said opposed portions, e. whereby said peripheral groove means provides a groove means of varying width for selective mounted spacing with said strain relief bushing.
