ABSTRACT:
A method of bonding a metal termination member including an electrical connector to an electrical cable designed for underwater operation having a plurality of insulated electrical wires, an internal armor layer of spirally wound wires, and a tough polyurethane protective jacket including the steps of splitting the external jacket longitudinally and peeling it away from the remainder of the cable, connecting the electrical wires to the connector member, attaching the wires of the armor layer to the termination member, cleaning and priming the metal surfaces of the termination member and the armor wires with a suitable thermoplastic adhesive which will adhere to metal and to polyurethane, repositioning the split halves of the polyurethane jacket around the end of the cable and the termination member, placing the termination assembly in a mold and subjecting it to heat and pressure sufficient to cause the polyurethane jacket material to flow sufficiently to bond the split halves of the jacket together and to the surface of the termination member, cooling or allowing the assembly to cool and removing the terminated assembly from the mold.
