Abstract: A self-aligning electrical connector is provided for aligning and connecting multiple pins of a male coupler with corresponding multiple pin sockets of a female coupler in a blind environment. A cylindrical standpipe is attached to and extends axially from the female connector. The end of the standpipe remote from the female coupler comprises a ramp or cam sloping to a lug slot in the standpipe that extends toward the female coupler. The male coupler includes a lug comprising a cam follower or roller for following the cam of the standpipe. During connection of the couplers, the action of the cam follower on the cam causes axial rotation of the male coupler until the cam follower engages the lug slot to align the couplers. A jackscrew extending through a longitudinal bore along the axis of the male coupler engages a threaded socket located at the axis of the female coupler to draw the pins of the male coupler into mating connection with the pin sockets of the female coupler.
