ABSTRACT:
A contact retention system for a housing for a battery cell is described which comprises a springy L-shaped retention member, a battery housing with a wall and a floor, with a catchment on both the wall and the floor, and contacts disposed between the base of the L-shaped retention member and the floor of the housing. The vertex of the L-shaped retention member is pushed toward the corner of the wall and the floor of the housing, and the ends of the L are restrained by the catchments. Any force exerted on the upper portion of the L-shaped retention member, pushing the upper portion toward the wall, causes the base of the L-shaped retention member to push the contacts toward the floor of the housing. The battery cells themselves provide the force on the upper portion of the L-shaped retention member. The contact system provides low-cost, easily manufacturable way to secure push-in contacts to a battery housing.
