Battery pack and wiring substrate
First Claim
1. A battery pack for supplying electricity to an electronic device, the battery pack comprising:
- a main body that includes a battery cell, an external shape of the main body being substantially symmetric with respect to a center line of a cover unit in a width direction, the main body having a circular arc shape on a side face;
a terminal unit arranged on a front face of the battery pack, the terminal unit including a plurality of terminals; and
the cover unit arranged on the terminal unit, the cover unit including a plurality of openings which each uncover one of the plurality of terminals, the openings being arranged in a line along a width direction on a front face of the battery pack, the openings including, in an order along the width direction, a first opening which uncovers a part of a positive terminal, a second opening which uncovers a part of a temperature detection terminal, a third opening which uncovers a part of a negative terminal, and a fourth opening which uncovers a part of a terminal of the plurality of terminals, the first opening and the second opening being arranged on one side with respect to the center line in the width direction of the cover unit, the fourth opening being arranged on an opposite side to the one side with respect to the center line in the width direction of the cover unit, a mirror image of the second opening onto the opposite side with respect to the center line in the width direction overlaps with the fourth opening, and the first opening being arranged asymmetrically to the fourth opening with respect to the center line in the width direction of the cover unit.

Abstract
A battery pack includes a pack body that includes a battery cell and that has an external shape substantially symmetric with respect to the horizontal and vertical axes, viewed from a front face on which terminals are arranged, and a terminal unit on the front face. The terminal unit includes a positive terminal, a negative terminal, a control terminal, and a temperature detection terminal for outputting temperature data. The positive terminal and the negative terminal are arranged on one side with respect to a center line in the width direction of the pack body. The control terminal is arranged symmetrically to the temperature detection terminal with respect to the center line in the width direction of the pack body.
