Abstract
Abstract A ground clamp arrangement for electrical cables of the type having neutral or ground potential wires concentrically surrounding the insulating jacket of the cable comprises a strip deformable into a collar for disposition radially between the jacket and the ground wires. A clamping ring encircles the ground wires and is tightened against the wires which are thereby pressed against the collar. The collar has interlocking overlapped ends that prevent diametral reduction of the collar so that reduction of the diameter of the cable jacket is prevented. The clamping ring has a terminal for attaching a wire to ground a telephone cable or the like. In the method the deformable member is inserted under several of the neutral wires, then bent around the cable, then pushed under all of the neutral wires to form the collar, after which the clamping ring is applied.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
A ground clamping arrangement for forming a conductive connection with an electrical cable having a conductive core, a surrounding jacket of insulating material, and a series of grounding wires helically disposed over said insulating jacket in substantially concentric relation therewith and with the wires being circumferentially spaced apart, said arrangement being remote from a cable splice or termination and comprising a member deformable into a collar radially interposed between the jacket and the grounding wires, and a clamp having an electrically conductive ring for enveloping said wires in the region of said collar and including means for constricting said ring to apply radially inward pressure against said wires and cause said wires to impinge snugly upon said collar, and means preventing constriction of said collar under pressure from said ring, thereby to prevent diametral reduction of said jacket, said grounding wires being continuous and maintaining their helical lay across the width of said collar and for substantial distances on opposite sides of said arrangement.
Claim 2
Dependent Claim
164 words
A ground clamping arrangement for forming a conductive connection with an electrical cable having a conductive core, a surrounding jacket of insulating material, and a series of grounding wires helically disposed over said insulating jacket in substantially concentric relation therewith and with the wires being circumferentially spaced apart, said arrangement being remote from a cable splice or termination and comprising a member deformable into a collar radially interposed between the jacket and the grounding wires, and a clamp having an electrically conductive ring for enveloping said wires in the region of said collar and including means for constricting said ring to apply radially inward pressure against said wires and cause said wires to impinge snugly upon said collar, and means preventing constriction of said collar under pressure from said ring, thereby to prevent diametral reduction of said jacket, said grounding wires being continuous and maintaining their helical lay across the width of said collar and for substantial distances on opposite sides of said arrangement.
Claim 3
Dependent Claim
164 words
A ground clamping arrangement for forming a conductive connection with an electrical cable having a conductive core, a surrounding jacket of insulating material, and a series of grounding wires helically disposed over said insulating jacket in substantially concentric relation therewith and with the wires being circumferentially spaced apart, said arrangement being remote from a cable splice or termination and comprising a member deformable into a collar radially interposed between the jacket and the grounding wires, and a clamp having an electrically conductive ring for enveloping said wires in the region of said collar and including means for constricting said ring to apply radially inward pressure against said wires and cause said wires to impinge snugly upon said collar, and means preventing constriction of said collar under pressure from said ring, thereby to prevent diametral reduction of said jacket, said grounding wires being continuous and maintaining their helical lay across the width of said collar and for substantial distances on opposite sides of said arrangement.
Claim 4
Dependent Claim
164 words
A ground clamping arrangement for forming a conductive connection with an electrical cable having a conductive core, a surrounding jacket of insulating material, and a series of grounding wires helically disposed over said insulating jacket in substantially concentric relation therewith and with the wires being circumferentially spaced apart, said arrangement being remote from a cable splice or termination and comprising a member deformable into a collar radially interposed between the jacket and the grounding wires, and a clamp having an electrically conductive ring for enveloping said wires in the region of said collar and including means for constricting said ring to apply radially inward pressure against said wires and cause said wires to impinge snugly upon said collar, and means preventing constriction of said collar under pressure from said ring, thereby to prevent diametral reduction of said jacket, said grounding wires being continuous and maintaining their helical lay across the width of said collar and for substantial distances on opposite sides of said arrangement.
Claim 5
Dependent Claim
41 words
A ground clamp arrangement according to claim 1 in which the means preventing construction of said collar comprises overlapping parts of the deformable member with one of the parts having a protrusion that fits into an opening in the other part.
Claim 6
Dependent Claim
56 words
A ground clamp arrangement according to claim 1 in which said deformable member comprises an elongated strip having notches spaced along the length thereof, and at least one protrusion at one end portion of the strip for engagement with a notch upon said deforming into said collar with said end portion overlapping at least one notch.
Claim 7
Dependent Claim
31 words
A ground clamp arrangement according to claim 1 in which said clamp has means for securing an electrical conductor thereto so that the conductor may be grounded by said grounding wires.
Claim 8
Independent Claim
149 words
A method of providing a ground connection to the ground wires of an electrical cable in which the ground wires surround an insulating jacket of the cable in substantially concentric relationship therewith and wherein the jacket encloses a conductive core, said method comprising inserting a strip radially between the ground wires and the jacket and shaping the strip to provide a collar that surrounds the jacket and with the strip having portions overlapping over a part of the circumference of the collar thus formed, interlocking said overlapped portions such that the collar remains substantially at a fixed diameter which is at least as great as the outer diameter of the jacket, and applying a clamping ring over said wires in the region of said collar to impose constricting pressure on said wires to urge them against said collar while said collar substantially prevents reduction of diameter of said jacket.
Claim 9
Independent Claim
149 words
A method of providing a ground connection to the ground wires of an electrical cable in which the ground wires surround an insulating jacket of the cable in substantially concentric relationship therewith and wherein the jacket encloses a conductive core, said method comprising inserting a strip radially between the ground wires and the jacket and shaping the strip to provide a collar that surrounds the jacket and with the strip having portions overlapping over a part of the circumference of the collar thus formed, interlocking said overlapped portions such that the collar remains substantially at a fixed diameter which is at least as great as the outer diameter of the jacket, and applying a clamping ring over said wires in the region of said collar to impose constricting pressure on said wires to urge them against said collar while said collar substantially prevents reduction of diameter of said jacket.
