Abstract: An intermediate portion of the outer insulation of a shielded electrical cable is removed near an end of the cable. A remaining small segment of the outer insulation at the cable end is moved axially inward along the cable to bunch up an exposed conductive braid of the cable. The bunched up braid is pinched to form a flattened, bell-shaped element on two opposite sides of inner conductive wires of the cable. The inner wires are attached to electrical terminals and the terminals are inserted into an insulator mounted within a conductive connector shield. The flattened elements are simultaneously aligned between opposite crimp arms extending from sides of the connector shield. The arms are crimped onto the flattened elements using an ultrasonic/vibration type crimping process or a shear lock crimping process. Since the flattened braid elements extend away from the cable, the crimping process is offset from the inner wires.
