Abstract
The connector includes an annular connector body that is substantially comprised of copper, and an annular insert portion made of brass and clad with tin. Apertures are made through the wall of the insert portion. The insert portion is configured to have an exterior frictionally fit within the connector body. Inserting a stranded aluminum cable into the annular insert portion and crimping the connector body, the insert portion and the cable, causes the outer strands of the stranded aluminum cable to be extruded through the plurality of apertures, removing oxide film on the exterior surface of the aluminum cable and forming a sealed electrical connection between the aluminum cable and the copper connector body.
