Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A splice construction for a pair of electrical cables in end to end relation, each cable having a core and a composite covering over said core, said covering comprising an inner layer of metal and an outer layer of thermoplastic resin, a terminal portion of said covering being longitudinally slit forming a plurality of circumferentially spaced, longitudinally extending tabs, said tabs being bent back disposing the metal layer portions thereof in an uppermost, bare condition, annular metal means in surface contact with said bare metal layer portions of said bent back tabs to retain said tabs in their bent back position and conductor means electrically interconnecting the annular metal means of one cable with the annular metal means of the other cable.
Claim 2
Dependent Claim
122 words
A splice construction for a pair of electrical cables in end to end relation, each cable having a core and a composite covering over said core, said covering comprising an inner layer of metal and an outer layer of thermoplastic resin, a terminal portion of said covering being longitudinally slit forming a plurality of circumferentially spaced, longitudinally extending tabs, said tabs being bent back disposing the metal layer portions thereof in an uppermost, bare condition, annular metal means in surface contact with said bare metal layer portions of said bent back tabs to retain said tabs in their bent back position and conductor means electrically interconnecting the annular metal means of one cable with the annular metal means of the other cable.
Claim 3
Dependent Claim
34 words
A splice construction as in claim 1 wherein the thermoplastic layer is removed from the terminal portiOns of said covering of each cable exposing opposite surface portions of said metal layer of each cable.
Claim 4
Dependent Claim
23 words
A splice construction as in claim 1 and further including a ring member disposed between said tabs and opposed portions of said covering.
Claim 5
Dependent Claim
43 words
A splice construction as in claim 1 wherein said annular metal means includes clamping means in engagement with the tabs on each cable, rigid means in opposed relation to the inner surface portions of said tabs for resisting compression by said clamping means.
Claim 6
Dependent Claim
56 words
A splice construction as in claim 1, wherein said annular metal means comprises a spiral coil of wire having its turns in contact with and extending transversely of said tabs, said conductor means comprising a wire portion interconnecting the spiral coil of wire of one cable with the spiral coil of wire of the other cable.
