Abstract

This invention is a battery charger having a pocket for charging a battery. The pocket is covered by a door which has a battery retention latch. When the door is open, and a battery is inserted into the pocket, the battery retention latch of the door exerts force upon the battery in a direction towards the charging contacts located in the base of the pocket. In so doing the door and battery retention latch hold the battery against the charging contacts, thereby enduring a good electrical connection. The battery retention latch also has a convex detente which keeps the door closed when no battery is present. Additionally, the charger may have a pocket for charging a phone and battery combination as well.

Claims

1. A battery charger comprising a pocket for charging a battery and a door having a battery retention latch for holding a battery in the pocket.

2. The charger of claim 1, further comprising a retention latch recess wherein the retention latch mates with the retention latch recess when the door is closed.

3. The charger of claim 2, wherein the battery retention latch comprises a convex detente.

4. The charger of claim 3, further comprising auxiliary contacts for delivering power to the pocket.

5. The charger of claim 4, wherein the battery retention latch exerts force upon a battery in a direction towards the auxiliary contacts.

6. The charger of claim 5, wherein the door has a curvature.

7. The charger of claim 6, wherein the door is made of one of the materials selected from the group consisting of polycarbonate, plastic, styrene, fiberglass, metal, and wood.

8. The charger of claim 7, wherein the door further comprises finger grasps along the edges of the door.

9. The charger of claim 8, further comprising a second pocket for charging a phone and battery combination.

10. The charger of claim 9, wherein the second pocket further comprises a mating contact for delivering power to the phone and battery combination.

11. The charger of claim 10, further comprising a circuit board having electrical components mounted thereon for delivering power to the auxiliary mating contacts of the pocket and to the mating contacts of the second pocket.
