Abstract
Abstract A pair of concentric hollow metallic sleeves are provided with sheath engaging means which may be in the form of raised protrusions disposed on one or both of the opposing surfaces of said sleeves to engage and electrically join the sheath of a sheathed cable to an external conductor upon the radial compression of the outer one of said sleeves after positioning a portion of the sheath and the external conductor within the annular gap existing between said sleeves. The resulting composite structure provides secure mechanical and electrical engagement between the external conductor, the sheath of the sheathed cable and the inner and outer metallic sleeves while additionally providing a smooth burr-free termination thereat. The sheath engaging means may comprise a series of raised ridges extending either parallel to the longitudinal axis of each of the sleeves or oblique thereto in selective patterns. The inner or outer sleeves may be further provided with selectively formed recesses designed to at least partially encompass the external conductor while additional recesses may be provided within the outer surface of the outer sleeve to relieve the stress formed thereby by the compression of the outer sleeve about the inner sleeve.

Claim 1
Independent Claim
202 words
Means for joining an external conductor to the sheath of a metallically sheathed cable comprising: a first hollow metallic sleeve member having an inner surface and an outer surface; a second hollow metallic sleeve member having an inner surface and an outer surface, said first sleeve member being arranged to fit coaxially within said second sleeve member while providing a predetermined annular gap therebetween for receiving a portion of the sheath of a metallically sheathed cable within said gap; and insulation piercing sheath engaging means selectively positioned about at least one of said first member outer surface and said second member inner surface; said second sleeve member being compressible about said first sleeve member so as to cause said sheath engaging means to engage such cable sheath portion and an external conductor interposed within said gap to electrically join such external conductor to such cable sheath portion at least through one of said first sleeve member and said second sleeve member upon the compression of said second sleeve member about said first sleeve member, said first sleeve member outer surface having at least one generally longitudinally extending recess arranged to at least partially accommodate a given length of such external conductor therewithin.
Claim 2
Dependent Claim
202 words
Means for joining an external conductor to the sheath of a metallically sheathed cable comprising: a first hollow metallic sleeve member having an inner surface and an outer surface; a second hollow metallic sleeve member having an inner surface and an outer surface, said first sleeve member being arranged to fit coaxially within said second sleeve member while providing a predetermined annular gap therebetween for receiving a portion of the sheath of a metallically sheathed cable within said gap; and insulation piercing sheath engaging means selectively positioned about at least one of said first member outer surface and said second member inner surface; said second sleeve member being compressible about said first sleeve member so as to cause said sheath engaging means to engage such cable sheath portion and an external conductor interposed within said gap to electrically join such external conductor to such cable sheath portion at least through one of said first sleeve member and said second sleeve member upon the compression of said second sleeve member about said first sleeve member, said first sleeve member outer surface having at least one generally longitudinally extending recess arranged to at least partially accommodate a given length of such external conductor therewithin.
Claim 3
Dependent Claim
255 words
Means for joining an external conductor to the sheath of a metallically sheathed cable comprising: a first hollow metallic sleeve member having an inner surface and an outer surface; a second hollow metallic sleeve member having an inner surface and an outer surface, said first sleeve member being arranged to fit coaxiAlly within said second sleeve member while providing a predetermined annular gap therebetween for receiving a portion of the sheath of a metallically sheathed cable within said gap; and insulation piercing sheath engaging means selectively positioned about at least one of said first member outer surface and said second member inner surface; said second sleeve member being compressible about said first sleeve member so as to cause said sheath engaging means to engage such cable sheath portion and an external conductor interposed within said gap to electrically join such external conductor to such cable sheath portion at least through one of said first sleeve member and said second sleeve member upon the compression of said second sleeve member about said first sleeve member, said means further comprising longitudinally extending slotted portions disposed selectively about said outer surface of said second sleeve member to at least partially relieve the stress in said second sleeve member as said second sleeve member is compressed about said first sleeve member, said sheath engaging means comprising longitudinally extending recessed portions disposed selectively within said inner surface of said second sleeve member and in general coincidence with said longitudinally extending slotted portions disposed about said second sleeve member outer surface.
Claim 4
Dependent Claim
255 words
Means for joining an external conductor to the sheath of a metallically sheathed cable comprising: a first hollow metallic sleeve member having an inner surface and an outer surface; a second hollow metallic sleeve member having an inner surface and an outer surface, said first sleeve member being arranged to fit coaxiAlly within said second sleeve member while providing a predetermined annular gap therebetween for receiving a portion of the sheath of a metallically sheathed cable within said gap; and insulation piercing sheath engaging means selectively positioned about at least one of said first member outer surface and said second member inner surface; said second sleeve member being compressible about said first sleeve member so as to cause said sheath engaging means to engage such cable sheath portion and an external conductor interposed within said gap to electrically join such external conductor to such cable sheath portion at least through one of said first sleeve member and said second sleeve member upon the compression of said second sleeve member about said first sleeve member, said means further comprising longitudinally extending slotted portions disposed selectively about said outer surface of said second sleeve member to at least partially relieve the stress in said second sleeve member as said second sleeve member is compressed about said first sleeve member, said sheath engaging means comprising longitudinally extending recessed portions disposed selectively within said inner surface of said second sleeve member and in general coincidence with said longitudinally extending slotted portions disposed about said second sleeve member outer surface.
