Patent ID: 8575466

Claim:
An electrical connector assembly for engaging and completing electrical contact with a receiving member having a receiving contact portion, comprising: a pin member operatively couplable to an electricity source, the pin member having first and second end portions and being electrically conductive; a connector body having a closed end, an open end, a sidewall extending between the closed and open ends, and an interior area, the closed end having an aperture having the pin member therein with the first end portion of the pin member extending at least partially into the interior area; a connector plate in the interior area of the connector body and positioned adjacent to the closed end of the connector body, the connector plate being electrically conductive and engaging the first end portion of the pin member and providing an electrical connection therebetween; an insulator sleeve disposed in the interior area of the connector body and adjacent to the sidewall of the connector body; an electrically conductive biasing member disposed in the interior area of the connector body, the biasing member having a first end portion in engagement with the connector plate, and wherein the insulator sleeve is disposed between the biasing member and the connector body; an electrically conductive ball track positioned within the interior area of the connector body and in engagement with a second end portion of the biasing member, the ball track having a concave seating portion facing toward the open end of the connector body and defining a rolling surface; and an electrically conductive ball disposed in the open end portion of the connector body and seated in the concave seating portion of the ball track, the ball and ball track being configured to allow the ball to roll relative to the connector body while maintaining engagement with the rolling surface of the ball track, the biasing member urging the ball track into engagement with the ball, the open end of the connector body being sized to retain the ball at least partially within the interior area, and the ball being moveable with the ball track in the interior area toward the closed end of the connector body upon compression of the biasing member, the ball being configured to roll along a portion of the receiving member and to electrically engage the receiving contact portion while maintaining electrical contact with the ball track to achieve electrical interconnection between the pin member and the receiving member.
