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
277 words
A stamping strip for the progressive stamping of metal electrical crimpable parts for attaching to an electrical lead including a conductor portion in a plastic molded electric plug, said stamping strip including, an end strip, said end strip at the outer periphery of said stamping strip, said end strip extending longitudinally along the length of said stamping strip, a stamped metal electrical lead safety crimp portion for attachment to said electrical lead, said stamped metal electrical lead safety crimp portion extending inward from said end strip, a spacer portion, said spacer portion having a first and second end, said first end of said spacer portion at said end strip, said spacer portion along its length spaced away from said stamped metal electrical lead safety crimp portion, a link portion, said link portion extending from said second end of said spacer portion, a stamped metal electrical part for attachment to said electrical conductor portion of said electrical lead, said stamped metal electrical part including a body and a crimp end, said link portion linked to said stamped metal electrical part between said crimp end and said body, said crimp end separate from and spaced away from said stamped metal electrical lead safety crimp portion, and said crimp end further aligned with said stamped metal electrical lead safety crimp portion, whereby said crimp end when crimped to said conductor portion of said electrical lead and said stamped metal electrical lead safety crimp portion when crimped to said electrical lead when said end strip and said spacer portion and said link portion are severed from said stamping strip are separate and spaced away from each other along said electrical lead.
Claim 2
Dependent Claim
