Abstract
Abstract A progressive stamping strip for electrical parts is provided with a spaced away wire safety crimp. The stamping strip may be used to automatically crimp leads to both the electrical part and the wire safety crimp. The wire safety crimp is severed from the stamping strip separate from the electrical part. The wire safety crimp retains the wires together and retains them in the plug. The present invention provides an electrical part with a wire safety crimped on a lead, as well as a molded plug with the wires protected against exposure from the plug.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
In combination an electrical lead, said electrical lead including a conductor portion, a stamped metal electrical part including a single crimp end, said crimp end crimped to said conductor portion of said electrical lead, said crimp end having no extensions therefrom which do not directly contact said conductor portion, a separate single stamped metal electrical lead safety crimp part, said stamped metal electrical lead safety crimp part crimped to said electrical lead, said stamped metal electrical lead safety crimp part having no extensions therefrom which do not directly contact said electrical lead, said crimp end and said crimp part located adjacent and spaced away from each other along said electrical lead, said lead being bendable between said crimp end and said crimp part, said stamped metal electrical lead safety crimp part and said crimp end of said stamped metal electrical part engagable with the molding plastic of a molded plug, whereby said stamped metal electrical lead safety crimp part retains said electrical lead in strain relief engagement within said molded plug.
