Abstract
Abstract A ground connector for a jacketed, interlocked armored cable includes a body portion, a resilient grommet, a frictional washer and a compression nut. A longitudinally split metallic grounding ring is also provided. A first end of the grounding ring is seated in a bore formed interiorly of the body portion. The opposite second end of the grounding ring is provided with a plurality of fingers as well as generally U-shaped connecting sections for joining the fingers to the second end of the cylindrical wall of the grounding ring. The connecting sections and the fingers are both deflectable upon assembly of the connector. The fingers, which are initially at an angle with respect to the longitudinal axis of the connector, point in the same direction as the direction of cable assembly. The free ends of the fingers act like barbs to thereby minimize retraction of the cable.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
223 words
A grounding connector for coupling a jacketed, armored cable to a utilization device such as a junction box, said connector comprising the combination of a metallic body portion having first and second external threads at opposite ends thereof, respectively, for engagement by said first threads with the utilization device, a resilient grommet having at least a portion thereof positioned within said body portion and arranged to bear against an outside surface of the cable in an assembled condition, a compression nut arranged to mate with said second threads on said body portion to thereby exert a force on said grommet whereby said grommet is compressed between said body portion and the outside surface of the cable, and a metallic grounding ring disposed within said body portion, said grounding ring having at least a partially circumferential, axially extending side wall defined by first and second ends, said grounding ring further including at least one elongated finger integral with said grounding ring side wall proximate said first end thereof, one end of said finger pointing in a direction of the body portion end having said first threads, said direction being the direction of cable insertion, said side wall of said grounding ring being in contact with said body portion, whereby, in the assembled condition, said finger is in contact with the armor of the cable.
Claim 2
Dependent Claim
223 words
A grounding connector for coupling a jacketed, armored cable to a utilization device such as a junction box, said connector comprising the combination of a metallic body portion having first and second external threads at opposite ends thereof, respectively, for engagement by said first threads with the utilization device, a resilient grommet having at least a portion thereof positioned within said body portion and arranged to bear against an outside surface of the cable in an assembled condition, a compression nut arranged to mate with said second threads on said body portion to thereby exert a force on said grommet whereby said grommet is compressed between said body portion and the outside surface of the cable, and a metallic grounding ring disposed within said body portion, said grounding ring having at least a partially circumferential, axially extending side wall defined by first and second ends, said grounding ring further including at least one elongated finger integral with said grounding ring side wall proximate said first end thereof, one end of said finger pointing in a direction of the body portion end having said first threads, said direction being the direction of cable insertion, said side wall of said grounding ring being in contact with said body portion, whereby, in the assembled condition, said finger is in contact with the armor of the cable.
Claim 3
Dependent Claim
23 words
A connector according to claim 1, wherein there is a plurality of said finger, said fingers being angularly spaced apart from each other.
Claim 4
Dependent Claim
35 words
A connector according to claim 2, wherein said fingers are initially disposed at an angle with respect to the longitudinal axis of said grounding ring prior to being engaged by the armor of the cable.
Claim 5
Dependent Claim
31 words
A connector according to claim 1, wherein said one end of said finger is arranged to engage the outer surface of the armor of the cable for inhibiting the disassembly thereof.
Claim 6
Dependent Claim
40 words
A connector according to claim 1, wherein said grounding ring includes a U-shaped member having a first leg thereof integral with said first end of said grounding ring side wall and having a second leg thereof integral with said finger.
Claim 7
Dependent Claim
35 words
A connector according to claim 1, wherein said body portion includes an internal, transverse seat and wherein said second end of said grounding ring side wall is positioned against said seat in the assembled condition.
Claim 8
Dependent Claim
18 words
A connector according to claim 6, wherein said second end of said grounding ring side wall is flat.
Claim 9
Dependent Claim
25 words
A connector according to claim 1, wherein there is further included a friction washer positioned intermediate a portion of said grommet and said compression nut.
Claim 10
Dependent Claim
33 words
A connector according to claim 8, wherein said friction washer is conical and is positioned between a conical surface at one end of said grommet and a conical bore in said compression nut.
Claim 11
Dependent Claim
24 words
A connector according to claim 1, wherein said grounding ring is split across said side wall from said first end to said second end.
