letter 34 a 34 in fig1 while the remaining length of the wire receiving portion 50 is crimped less severely to a final height indicated by the letter 34 b 34 in fig1 the wire receiving portion 50 is compressed generally uniformly over the entire length d to provide a generally constant interior crimp height a throughout the entire length d thereof as will be described in greater detail hereafter the resulting crimp provides a controlled corrosion zone indicated by the letter 34 z 34 generally adjacent the juncture between the terminating end of the wire receiving portion 50 and the adjacent extruded portion of the conductor 52 the controlled corrosion zone z is generated by subjecting the length of conductor situated within the portion of the connector indicated by the letter d to a sufficient compressive force to work harden and extrude a segment thereof out of the adjacent end of the connector in conformance with a given ratio between the heights a and b of the completed connection so as to cause a predetermined change in the electromotive potential of the extruded segment of the conductor by stressing a given segment of the conductor 52 to a predetermined degree such segment is caused to be less noble or more anodic than the remainder of the conductor thereby operating as a sacrificial anode with respect to the less severely stressed portion of the connection accordingly the exposed segment of the conductor.
