ABSTRACT:
A method of manufacturing an electrical contact with a crimp ear from a flat ribbon of conductive material including applying a force to the ribbon to form an adjacent pair of approximately semicylindrical depressions on opposite sides of the centerline of the ear, shearing the ribbon at the depression bisectors to form a pair of legs on opposites of the centerline, and forming the legs into a predetermined shape about the centerline. Forming the legs includes straightening the legs and bending the legs to the appropriate predetermine relative angle. Optionally, the ear is coined. Optionally, serrations are inscribed across the ear.
