Abstract

Provided is a fuse board having a metal plate, a connector that connects to a battery, a fuse that links the metal plate and the connector part, and an insulating resin film that is adhered to the fuse part. The wiring pattern of the fuse has a curved part, and the insulating resin film is in the form of a rectangular sheet that covers one face of the fuse.

Description

technical field [0001] The present invention relates to a fuse board and a battery block provided with the fuse board. Background technique [0002] By combining a plurality of unit cells, a battery block having a desired voltage or current amount can be obtained. In a battery block, electrode terminals of a plurality of unit cells are connected to one electrode plate. Therefore, there is a possibility that the battery block itself may be short-circuited when an excess current flows through the unit cells. Therefore, a fuse for disconnecting between the electrode plate and the unit cell is sometimes provided to prevent the above-mentioned short circuit. [0003] In order to provide a fuse between the unit cell and the electrode plate, the following technology has been proposed: in addition to forming the fuse by liner welding the electrode terminal of the unit cell and the electrode plate, the fuse is also formed by wire bonding (cf. Patent Document 1). [0004] In addit...
