Abstract
Abstract The invention comprises a grounding foil member having one or more cavities therein, formed of tangs for securing circuit elements such as filters thereto by means of direct contact. The outer edge of the foil member which contacts the inner shell of a conductor is formed of flaps bent at an angle. Each of the flaps deflect upon entering the shell which completes the electrical circuit between the filter and the shell through the ground foil. The filter may be removed from the ground foil and the ground foil from the shell with relative ease and with no soldering required.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
In combination a grounding foil retaining removable electrical elements within a conductor and providing a ground connection between said elements and said conductor; said grounding foil being of resilient sheet metal and comprising: a foil member whose outer dimensions are slightly smaller than the confines of said conductor, said foil member having a plurality of tabs extending therefrom resiliently engaging the inner surface of said conductor; means on said foil surface defining a plurality of cavities each formed from a plurality of short tangs, said tangs deflecting over said electrical element with said electrical element inserted in said cavity; and said tangs being angularly disposed with respect to a plane defining the surface of said foil adjacent said tangs prior to insertion of said elements in said cavity.
Claim 2
Dependent Claim
128 words
In combination a grounding foil retaining removable electrical elements within a conductor and providing a ground connection between said elements and said conductor; said grounding foil being of resilient sheet metal and comprising: a foil member whose outer dimensions are slightly smaller than the confines of said conductor, said foil member having a plurality of tabs extending therefrom resiliently engaging the inner surface of said conductor; means on said foil surface defining a plurality of cavities each formed from a plurality of short tangs, said tangs deflecting over said electrical element with said electrical element inserted in said cavity; and said tangs being angularly disposed with respect to a plane defining the surface of said foil adjacent said tangs prior to insertion of said elements in said cavity.
Claim 3
Dependent Claim
50 words
A grounding foil in accordance with claim 1 wherein the outer edge defined by said tabs is slightly greater than said inner dimension of said conductor, said tabs deflecting upon insertion of said foil into said conductor, thereby providing a constant pressure and contact between said foil and said conductor.
Claim 4
Dependent Claim
54 words
A grounding foil in accordance with claim 1 wherein each of said cavity tangs acts independently of the other tangs of a cavity applying constant pressure to the outer surface of an electrical element; and upon removal of said electrical element from said cavity, said tangs being capable of returning to their normal position.
Claim 5
Dependent Claim
34 words
A grounding foil in accordance with claim 1 wherein said grounding foil is a thin flat member and is mounted in said conductor in a plane perpendicular to an axis defined by said conductor.
Claim 6
Dependent Claim
20 words
A grounding foil in accordance with claim 4 wherein said grounding foil is made of beryllium copper plated with silver.
