Abstract
Abstract An electrical connector of one material such as a copper alloy may be secured to a cable of a different material such as aluminum in an assembly which will resist loosening under heat, by securing the conductive strands of the cable within the internal bore of a tube of material akin to the material of the cable strands, and also disposing a portion of the connector within such internal bore, while a reinforcing ring is exteriorly disposed about said sleeve in the vicinity where the connector portion is located.
