ABSTRACT:
A latching system for a battery pack of a hand-held, portable electronic device. A primary latch on the front panel of the battery pack releasably engages a retaining shoulder portion within a battery housing to removably secure the battery pack in a fully installed, electrically connected position within the electronic device. Secondary latches are connected to the left and right side panels of the battery pack at a position away from the primary latch. Each secondary latch is adapted to releasably engage a secondary retaining shoulder within the housing to retain the battery pack in a partially removed position. Elongated electrical contacts are connected to the battery pack and provide electrical contact between the battery pack and the electronic as battery pack is moved from the installed position to the partially removed position. A switch coupled to the battery pack detects movement of the battery pack from the installed position. The primary and secondary latches each have an outwardly biased lever arm movably connected to the battery pack and a head member connected to the lever arm. The primary and secondary latches are arranged so the secondary latches are inaccessible until the battery pack is moved to the partially removed position.
