Abstract

A power source device (2) includes a plurality of small batteries (3), a plurality of bus, bars (4), a casing (5), and a battery cover (1). The small batteries (3) are stacked together in such a manner that positive electrodes (7), as well as negative electrodes (8), are alternately reversely directed. The bus bars (4) are embedded in the casing (5), and when the casing (5) covers end portions of the small batteries (3), the electrodes (7, 8) are connected together. The battery cover (1) includes a cover body (11), opening/closing covers (12), and hinges (13). The cover body (11) is attached to the casing (5). The opening/closing covers (12) can be displaced between their respective closed positions where the opening/closing covers (12) respectively cover the electrodes (7, 8) and their respective open positions where the electrodes (7, 8) are exposed.

Claims

1. A battery cover attachable to a battery assembly so as to partially cover the battery assembly, wherein the battery assembly includes at least two batteries each having a positive electrode at a first end thereof and a negative electrode at a second end thereof, the batteries being stacked together so that the positive electrode of one of the batteries and the negative electrode of the other one of the batteries are alternately juxtaposed, said battery cover comprising:

a cover body attachable to the battery assembly;

a hinge; and

at least one opening/closing cover pivotably connected to the cover body though the hinge,

wherein when the cover body has been attached to the battery assembly, the opening/closing cover can be displaced relative to the cover body between an open position where at least one of the juxtaposed positive and negative electrodes is exposed with the opening/closing cover and a closed position where the at least one of the juxtaposed positive and negative electrodes is covered with the opening/closing cover.

2. A battery cover according to

claim 1

, wherein the hinge is formed integrally with the cover body and the opening/closing cover, and is smaller in thickness than the cover body and the opening/closing cover.
