Abstract
A selectively applied crimping force is utilized to provide a stepped crimp to an electrical connection to create a discrete sacrificial anode from base conductor material thereby providing a controlled zone of corrosion which substantially increases the integrity and life of the electrical connection. This effect is achieved by crimping one portion of the connector to a greater extent than the remaining portion thereby extruding and work hardening a given length of the conductor to a predetermined degree to selectively alter the physical characteristics thereof. The degree to which each segment of the wire receiving portion of the connector is compressed may be defined as a ratio encompassing a given range of values designed to optimize the selective corrosion effect. Also disclosed are crimping dies for effecting the selectively stepped crimp, which dies are suitably proportioned to provide the necessary ratio of maximum to minimum crimp height.
