Abstract:
A method for connecting first and second electric cables, said method comprising:providing first and second cables, each said cable having a conductive core and an insulation layer surrounding the core; preparing an end of each said cable by removing the insulation and forming an exposed section of the core adjacent the end of the respective cable; providing an elongate rod-shaped terminal unitarily formed from a conductive material and having opposite first and second ends, a solid connecting portion disposed at a location between said first and second ends and first and second insertion holes being formed centrally in said first and second ends, said insertion holes being dimensioned to slidably receive the exposed sections of the respective cores of the respective first and second cables; mounting a tubular heat-shrinkable sleeve over the elongate rod-shaped terminal, said tubular heat-shrinkable sleeve having a first end projecting axially beyond the first end of the rod-shaped terminal and a second end projecting axially beyond the second end of the elongate rod-shaped terminal; performing a first heat-shrinking step on portions of said heat-shrinkable sleeve aligned with said elongate rod-shaped terminal such that central portions of said tubular heat-shrinkable sleeve between said first and second ends thereof tightly engage outer surface regions of said elongate rod-shaped terminal at substantially all locations between said first and second ends of said terminal; inserting the exposed conductive cores of the first and second cables through the respective first and second ends of the heat-shrinkable sleeve and into the respective first and second insertion holes of the terminal; crimping inwardly portions of said heat-shrinkable sleeve that were shrunk by the first heat-shrinking step and portions of said terminal aligned with said first and second insertion holes, such that crimped portions of said terminal electrically contact the exposed conductive cores of the first and second cables; performing a second heat-shrinking step on portions of said sleeve adjacent said first and second ends such that said sleeve shrinks into secure engagement with portions of said first and second cables adjacent said first and second ends of said terminal.
