ABSTRACT:
A battery box, particularly for use in toys, is capable of establishing electrical contact with battery terminals. The battery box includes a housing which bounds a compartment for accommodating at least one battery, but preferably a plurality of batteries therein. A pair of contact members is provided for the battery or each of the batteries, each of the contact members having a contact portion located in the compartment and adapted to contact one terminal of the battery. A mounting portion of one of the contact members of the pair is slidably received in an opening of an end wall of the housing and a leaf spring biases the contact member towards its extended position in which a contact portion of the contact member contacts and presses against one terminal of the respective battery. The leaf spring is located adjacent the surface of the end wall which faces away from the compartment. The slidably mounted contact member is plate-shaped and the opening of the end wall has a corresponding configuration. The contact portion diverges from its contact face toward the mounting portion.
