Abstract
A battery pack utilizes a battery pack contact assembly to ensure a good connection between the battery pack and the device being powered by the battery pack. The contact assembly includes a carrier, a first contact integral with the carrier, and a second contact integral with the carrier stamped from a conducting weldable material. A score line is provided between the carrier and the contacts. A selected portion of the contacts is plated with gold, defining an exposed weldable surface and a selectively plated surface. During assembly, the exposed weldable surface is welded to positive and negative terminal poles of the battery pack, and the carrier is fatigued along the score lines and removed. The resulting contacts are securely attached to the terminal poles of the battery pack and provide a gold-plated surface for contact with the battery pack powered device.
