ABSTRACT:
An electrical connector system is shown in which a sheet metal contact with an open barrel wire receiving portion is attached to a wire conductor by spirally crimping the open barrel closed upon the wire. The spiral crimp is formed from multiple opposed indents, each arranged at an angle to the longitudinal axis of the contact and each decreasing in depth to smoothly merge with the diameter of the open barrel portion to prevent stress build-up. Shoulders are provided on each side of the crimped surface of the open barrel to strengthen the contact and prevent distortion.
