Electronic device having a removable battery pack assembly

摘要

A battery pack assembly is removably insertable into a receptacle on a housing of an electronic receiver carried by an animal to control the movement of the animal relative to a predetermined area. The battery pack assembly supplies power to the electronic receiver. The receptacle for the battery pack has internal guide grooves and detentes along the guide grooves. The battery pack has lugs which slide within the guide grooves to guide the battery pack into position within the receptacle. The detentes cooperate with the movement of the lugs to lock the battery pack in position within the receptacle housing. A spring contained within the battery pack biases the battery pack relative to the receptacle to prevent the battery pack from inadvertently disengaging from the housing.
