  • Patent number: 6661196
    Abstract: This invention includes an electrically-conductive contact, preferably for use in battery chargers. The contact is manufactured from a springy metal material, like stainless steel. The contact includes a triangular shaped contour, capable of withstanding battery insertion force, and further capable of mating to battery contacts of varying depths. The contact includes a mechanical stop for preventing the contour from protruding too far through apertures in the battery charger pocket. A stem preloads the mechanical stop against a retaining wall. A lanced barb on a charger mount allows the contact to reside in the charger without the need of other adhesives, screws or rivets. A protrusion makes contact with an electrical pad on a printed circuit board. A protrusion extensor preloads the protrusion against the pad.
