Abstract
Abstract A two-piece, push-on type grounding clip for grounding a conductor (e.g. the shield of a shielded line or cable) to a metallic wall has a first, U-shaped, resilient metal clamp having an open end adapted for engagement with the edge of a metallic wall. The closed end of the first clamp has a transverse groove for receiving the conductor (e.g. a shielded cable). The walls forming the transverse groove are shaped and/or sized to cut the cable insulation (if any) and to form a secure electrical contact with a cable conductor (e.g. the shield of the cable). A second U-shaped resilient clamp has an open end with a transverse groove for receiving both the closed end of the first clamp and the conductor (e.g. shielded cable). The second clamp prevents the cable from backing out of the transverse groove of the first clamp and also exerts additional pressure on the first clamp's engagement with the metallic wall.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
103 words
A two-piece electrical connection clip for electrically connecting the electrically conductive shield of a shielded electrical cable to a first metallic member, said clip comprising: a first electrically conductive metallic clamp formed by two members that are joined at a common end, said two members providing a first opening dimensioned to receive and engage therewithin an edge of said first metallic member, said common end having a slot dimensioned to receive and engage therewithin said conductive shield of said shielded electrical cable; and a second clamp dimensioned to engage said first clamp and to securely retain said conductive shield within said second opening.
Claim 2
Dependent Claim
103 words
A two-piece electrical connection clip for electrically connecting the electrically conductive shield of a shielded electrical cable to a first metallic member, said clip comprising: a first electrically conductive metallic clamp formed by two members that are joined at a common end, said two members providing a first opening dimensioned to receive and engage therewithin an edge of said first metallic member, said common end having a slot dimensioned to receive and engage therewithin said conductive shield of said shielded electrical cable; and a second clamp dimensioned to engage said first clamp and to securely retain said conductive shield within said second opening.
Claim 3
Dependent Claim
20 words
A two-piece clip as in claim 1 wherein said first and second clamps are each integrally formed resilient metallic members.
Claim 4
Dependent Claim
23 words
A two-piece clip as in claim 1 or 2 wherein said first clamp includes internally-directed projections for engagement with said first metallic member.
Claim 5
Dependent Claim
20 words
A two-piece clip as in claim 3 wherein said second clamp includes internally-directed projections for engagement with said first clamp.
Claim 6
Dependent Claim
28 words
A two-piece clip as in claim 4 wherein said first clamp includes indentations on its outer surface for mated engagement with the internally-directed projections of said second clamp.
Claim 7
Dependent Claim
134 words
A push-on type grounding clip for grounding a shield of a shielded cable to a metallic wall, said clip comprising: a first U-shaped resilient electrically conductive clamp adapted for engagement at an open end thereof with the edge of the metallic wall, said first clamp having an open groove in the closed end thereof for receiving the shielded cable with the walls of said groove being dimensioned to contact the shield and thereby ground said shield to said metallic wall; and a second U-shaped, resilient clamp having a groove in an open end thereof dimensioned to receive said cable therewithin, said second clamp being adapted for engagement at its open end with both said closed end of said first clamp and said cable for maintaining said cable in said groove of said first clamp.
Claim 8
Dependent Claim
134 words
A push-on type grounding clip for grounding a shield of a shielded cable to a metallic wall, said clip comprising: a first U-shaped resilient electrically conductive clamp adapted for engagement at an open end thereof with the edge of the metallic wall, said first clamp having an open groove in the closed end thereof for receiving the shielded cable with the walls of said groove being dimensioned to contact the shield and thereby ground said shield to said metallic wall; and a second U-shaped, resilient clamp having a groove in an open end thereof dimensioned to receive said cable therewithin, said second clamp being adapted for engagement at its open end with both said closed end of said first clamp and said cable for maintaining said cable in said groove of said first clamp.
Claim 9
Dependent Claim
20 words
The clip of claim 6 wherein the first clamp includes stop tabs extending inwardly from the bottom of the groove.
Claim 10
Dependent Claim
24 words
The clip of claim 6 wherein the first clamp includes projections extending inwardly from the open end thereof for securely engaging the metallic wall.
Claim 11
Dependent Claim
31 words
The clip of claim 6 wherein the resilience of the second clamp, when in place, is such that it causes the first clamp to exert increased pressure on the metallic wall.
Claim 12
Dependent Claim
15 words
The clip of claim 6 wherein the first and second clamps are made of metal.
Claim 13
Dependent Claim
47 words
The clip of claim 6 wherein juxtaposed portions of the first clamp have openings formed therein and wherein the juxtaposed open ends of the second clamp have inwardly extending projections for cooperating with said openings to allow secure engagement of said second clamp to said first clamp.
Claim 14
Dependent Claim
29 words
The clip of claim 6 wherein the juxtaposed open ends of the second clamp are outwardly flared to allow easy engagement of said second clamp with the first clamp.
Claim 15
Dependent Claim
49 words
The clip of claim 6 adapted to ground the shield of an insulated cable wherein the walls of the groove in the closed end of the first clamp are sharp enough to cause said walls to cut through any outer cable insulation when pushed thereinto to ground said shield.
Claim 16
Dependent Claim
32 words
The clip of claim 6 wherein the juxtaposed open ends of the first clamp are outwardly flared to allow easy engagement of said first clamp with the edge of the metallic wall.
Claim 17
Dependent Claim
