Abstract

Abstract A water-tight termination of a coaxial submarine cable to a tail cable including a piece-part polyethylene molding over a polyethylene/copper/polyethylene laminate and continuity braid. Applied heat externally bonds the laminate to a plastic internal core forming the dielectric and to the piece part to form a water barrier.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 259 words
A termination assembly for water-tight connection of a tail coaxial cable to a submarine coaxial cable, said submarine cable having an inner conductor, a dielectric core surrounding said inner conductor, a generally tubular concentric outer conductor over said core and an outer jacket covering said outer conductor; said tail cable having a central conductor, a plastic dielectric about said central conductor and an outer conductor braid over said dielectric, comprising: a generally conical ferrule of metallic material and a substantially coaxial hollow metallic tube in communication with the smaller end of said ferrule, the inner conductor of said submarine cable being inserted axially into said metallic tube and being mechanically and electrically affixed therein; a molded dielectric plastic jacket over said ferrule and all except a projecting portion of said hollow metallic tube adjacent its end, said jacket tapering substantially down to the diameter of said plastic dielectric of said tail cable at its end opposite said hollow metallic tube projecting portion; first means including an auxillary conductive braid placed over said molded jacket; second means including a hollow conductive metallic generally conical member fitted over said molded jacket and being electrically and mechanically affixed to said first means braid at its larger end and to the outer conductor braid of said tail cable at its smaller end; third means including a second molded plastic part filling the gap between said molded jacket and the indented end of said submarine cable core, all of said molded plastic piece parts being heat fused together to form a water-tight continuous jacket.
Claim 2
Dependent Claim 259 words
A termination assembly for water-tight connection of a tail coaxial cable to a submarine coaxial cable, said submarine cable having an inner conductor, a dielectric core surrounding said inner conductor, a generally tubular concentric outer conductor over said core and an outer jacket covering said outer conductor; said tail cable having a central conductor, a plastic dielectric about said central conductor and an outer conductor braid over said dielectric, comprising: a generally conical ferrule of metallic material and a substantially coaxial hollow metallic tube in communication with the smaller end of said ferrule, the inner conductor of said submarine cable being inserted axially into said metallic tube and being mechanically and electrically affixed therein; a molded dielectric plastic jacket over said ferrule and all except a projecting portion of said hollow metallic tube adjacent its end, said jacket tapering substantially down to the diameter of said plastic dielectric of said tail cable at its end opposite said hollow metallic tube projecting portion; first means including an auxillary conductive braid placed over said molded jacket; second means including a hollow conductive metallic generally conical member fitted over said molded jacket and being electrically and mechanically affixed to said first means braid at its larger end and to the outer conductor braid of said tail cable at its smaller end; third means including a second molded plastic part filling the gap between said molded jacket and the indented end of said submarine cable core, all of said molded plastic piece parts being heat fused together to form a water-tight continuous jacket.
Claim 3
Dependent Claim 35 words
Apparatus according to claim 1 in which said second means conical member is coated with plastic material on both surfaces to permit heat fusing as a part of the water-tight structure of said termination assembly.
Claim 4
Dependent Claim 18 words
Apparatus according to claim 2 in which said molded plastic parts are made of a thermoplastic dielectric material.
Claim 5
Dependent Claim 29 words
Apparatus according to claim 2 in which said auxillary braid and said second means conical part are made of copper, said conical part being coated with said thermoplastic material.
Claim 6
Dependent Claim 12 words
Apparatus according to claim 3 in which said thermoplastic material is polyethylene.
