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

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.
