Abstract
A cable assembly (8, 80) including an electrical cable (10) having a flexible tubular jacket (12) and a reinforcing structure (14) attached to the outside of the jacket in a smooth sealing connection (30), and a method of using radio-frequency electrical energy, applied radially through the cable jacket (12) and the reinforcing structure (14), to make the connection (30). A shield conductor (26) inside the cable jacket (14) may be used as an RF electrode, with a second RF electrode (42, 44) circumscribing a portion of the cable (12) and the reinforcing structure (14) and shaping the outer surface of the connection. The RF energy may be used instead to activate an adhesive (108). An outer electrode (118) may be embedded in the reinforcing structure (116) in one variation of the invention.
