ABSTRACT:
A battery contact generally having three integrally formed portions. A first spring portion at a first end is electrically couplable to a rechargeable battery pack. A second spring portion at a second end is electrically coupled to a battery charging circuit. A retaining spring portion is located therebetween. The first, second and retaining spring portions are formed by a series of bends made in and along a single, electrically conductive, flat metal wire. A housing containing the battery charging circuit has a socket for receiving the rechargeable battery pack. The first spring portion is mechanically and removably retained by the housing and projects into the socket. The second spring portion is positioned between a bottom wall of the housing and a printed circuit board containing the battery charging circuit. The second spring portion is electrically coupled to a printed circuit board contact and is formed to provide multiple bends with additive beam flexure forces.
