Abstract
Abstract A grounding clip forming an electrical interconnection between a ground wire and an electrically conductive panel, such as used on an electrical appliance, is disclosed. This grounding clip comprises a stamped and formed member having a U shaped section with opposed walls extending from a bight for engagement with a panel. Tines or serrations are struck inwardly from each wall to grip the panel. A wire contact section is offset from the U shaped panel. A centrally disposed strain relief arm extends from the U shaped section and any force transmitted from the wire to the clip is in the form of a straight pull extending through the centrally disposed strain relief arm.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
145 words
A grounding clip for forming an electrical interconnection between a ground wire and an electrically conductive panel, the grounding clip comprising a stamped and formed member having a U-shaped section with opposed walls extending from a bight; tines protruding inwardly from each wall for gripping the panel; a wire contact section for establishing an electrical interconnection with the ground wire, and a strain relief arm extending from one said wall on the side of the bight opposites said walls, the other said wall having a slot from which the strain relief arm is formed, and wherein the free ends of the tines are inclined relative to the walls and extend toward the bight, the tines having a greater retention force when subjected to a straight pull exerted on the U-shaped section than when subjected to a force tending to impart rotation to the U-shaped section.
Claim 2
Dependent Claim
145 words
A grounding clip for forming an electrical interconnection between a ground wire and an electrically conductive panel, the grounding clip comprising a stamped and formed member having a U-shaped section with opposed walls extending from a bight; tines protruding inwardly from each wall for gripping the panel; a wire contact section for establishing an electrical interconnection with the ground wire, and a strain relief arm extending from one said wall on the side of the bight opposites said walls, the other said wall having a slot from which the strain relief arm is formed, and wherein the free ends of the tines are inclined relative to the walls and extend toward the bight, the tines having a greater retention force when subjected to a straight pull exerted on the U-shaped section than when subjected to a force tending to impart rotation to the U-shaped section.
Claim 3
Dependent Claim
37 words
The grounding clip of claim 1 wherein the strain relief arm extends from the center of the U-shaped section so that a force exerted on the wire is transferred to the U-shaped section as a straight pull.
Claim 4
Dependent Claim
19 words
The grounding clip of claim 2 wherein the tines comprise portions struck inwardly from the edges of the walls.
Claim 5
Dependent Claim
15 words
The grounding clip of claim 2 wherein the wire contact section comprises a crimp section.
Claim 6
Dependent Claim
44 words
The grounding clip of claim 2 wherein the wire contact section is disposed below the bight and on one side of the U-shaped section so that a force exerted on the wire contact section is transmitted as a rotary force to the U-shaped member.
Claim 7
Dependent Claim
30 words
The grounding clip of claim 6 wherein the strain relief arm and the wire contact section comprise deformable members configured to be crimped around associated portions of the ground wire.
Claim 8
Dependent Claim
53 words
The grounding clip of claim 6 wherein the one wall has a pilot hole aligned with the slot in the other wall so that a screw can be inserted through the slot when the grounding clip is properly aligned with a clearance hole in the panel and then tapped into the pilot hole.
