Battery pack

摘要

[Object] To prevent elements in a pack main body and an electronic apparatus from malfunctioning even if the pack main body having an outer shape line-symmetric in up and down directions and left- and right-hand directions is incorrectly attached.;[Solving Means] There are provided a pack main body 11 installing the battery cell 29 and a terminal portion 12 constituted of a plus terminal 12a, a minus terminal 12b, and a control terminal 12c that are provided on a front surface 11c of the pack main body 11. The plus terminal 12a, the minus terminal 12b, and the control terminal 12c are provided so as to be deviated to one end portion 11f in a width direction of the front surface 11c and arranged in an order of the plus terminal 12a, the control terminal 12c, and the minus terminal 12b. The sizes of the control terminal 12c, the plus terminal 12a, and the minus terminal 12b are increased in an order of the control terminal 12c, the plus terminal 12a, and the minus terminal 12b such that the control terminal 12c is formed to be the smallest. While being attachable to various electronic apparatuses, the pack main body can ensure a sufficient mechanical strength.
