Abstract
A sealed connection between an undersea coaxial line cable and a length of coaxial access cable connected to a repeater; the line cable comprising an axial conductor (11), insulation (12), a return path (13) and an outer sheath (14A); the access cable comprising an axial conductor (15), insulation, metal braiding (20A, B) forming a return path, and an outer sheath (14B); and the connection comprising a conical conductive metal connection part (16) for inter-connecting the axial conductors, a surface moulded layer of insulating thermoplastic material (17), a conductive connector (18) for interconnecting the return paths of the line cable and the access cable, and a reconstituted sheathing between the line cable and the access cable, wherein said conductive connector for inter-connecting the return paths comprises an aluminum flared tube fitted tightly over the surface-moulded insulation, with a layer of graft polyolefin or adhesive ionomer tape wound helically around the surface moulding being sandwiched in between the moulding and the flared tube, the wider end of the flared tube having a flared rim (19) receiving and being welded to the return path of the line cable, and the narro…
