Abstract
Abstract An end of a submarine coaxial cable is joined to an end of a repeater tail coaxial cable by replacing the free end of the aluminum outer conductor of the submarine coaxial cable with an aluminum alloy braid sheath, welding the sheath to the aluminum outer conductor, and fitting a composite water barrier assembly into the inner insulation at the free end of the submarine cable. The assembly comprises a copper alloy castellated sleeve, an aluminum alloy end piece friction welded to the castellated sleeve, and a high strength copper alloy liner. The aluminum alloy end piece is welded to the braided sheath, and the castellated sleeve is joined to the copper braid of the outer conductor of the repeater coaxial tail cable.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
A coaxial cable connection joining one coaxial cable to another coaxial cable comprising: inner and outer conductors for each cable, an end portion of the outer conductor of one cable being removed; a conductive braided sheath disposed around the end in place of said removed portion, one end of said sheath being welded to the outer conductor; an insulation layer surrounding the inner conductor of said one cable; a composite water barrier assembly fitted around said insulation layer; said assembly including a conducTive tube, an end of said tube being welded to the other end of said braided sheath, and a conductive castellated sleeve, an end of said sleeve being friction welded to the other end of said conductive tube; an outer conductive means connecting the other end of said castellated sleeve to the outer conductor of said other cable; an inner conductive means connecting an end of said inner conductor of said one cable to the inner conductor of said other cable; and dielectric means disposed between said inner and outer conductive means.
Claim 2
Dependent Claim
174 words
A coaxial cable connection joining one coaxial cable to another coaxial cable comprising: inner and outer conductors for each cable, an end portion of the outer conductor of one cable being removed; a conductive braided sheath disposed around the end in place of said removed portion, one end of said sheath being welded to the outer conductor; an insulation layer surrounding the inner conductor of said one cable; a composite water barrier assembly fitted around said insulation layer; said assembly including a conducTive tube, an end of said tube being welded to the other end of said braided sheath, and a conductive castellated sleeve, an end of said sleeve being friction welded to the other end of said conductive tube; an outer conductive means connecting the other end of said castellated sleeve to the outer conductor of said other cable; an inner conductive means connecting an end of said inner conductor of said one cable to the inner conductor of said other cable; and dielectric means disposed between said inner and outer conductive means.
Claim 3
Dependent Claim
20 words
A cable connection in accordance with claim 1 wherein said outer conductor of said other cable includes a copper braid.
Claim 4
Dependent Claim
31 words
A cable connection in accordance with claim 2 wherein said castellated sleeve is made of a copper-nickel-silicon alloy and said conductive tube and braided sheath are made of an aluminum-magnesium alloy.
Claim 5
Dependent Claim
39 words
A cable connection in accordance with the claim 3 wherein said connection further includes a high-strength conductive liner made of a beryllium-copper alloy interposed between said castellated sleeve and said insulation surrounding said inner conductor of said one cable.
Claim 6
Independent Claim
140 words
A method of terminating the aluminum outer conductor of a submarine coaxial cable and joining it to the copper braid outer conductor of a repeater tail cable, comprising the steps of: removing a portion of the aluminum outer conductor at the end of said coaxial cable and replacing said portion with an aluminum alloy braid sheath; welding said aluminum alloy braid sheath to said aluminum outer conductor; fitting a composite water barrier assembly into the inner insulation at the free end of said submarine cable, said assembly including a copper alloy castellated sleeve, an aluminum alloy end piece friction welded to said castellated sleeve, and a high-strength copper alloy liner; welding said aluminum alloy end piece to said aluminum alloy braid sheath; and joining said castellated sleeve to said copper braid of the outer conductor of said repeater tail cable.
Claim 7
