ABSTRACT:
A method, machine and termination for connecting two or more insulated wire ends includes placing them in a metal tube held between fusing electrodes. The electrodes are shaped to deform the tube and wires therein with the application of fusing pressure. During fusing, pressure builds first to press the assembly together, then heat and current are applied as the tube and internal wires are compressed. Fusing current first flows from a longitudinal region of the tube equally in both direction through the tube metal to soften the tube and distribute the fusing heat broadly. As the wire insulation is burned off or flows away, current also passes through the bare wire ends to aid the fusing process. For tinned copper tubes, some of the inside tin layer flows to wet copper surfaces and dissolve copper impurities. Some tin flows to seal small spaces between the fused wires. Some of the tin on the outside surface and inside surface of the tube may vaporize. A fusing machine for carrying out the method is suspended from a standard retractable winch cable so that the electrodes can be easily positioned in free space.
