Abstract

The present invention provides a fuse device having a fuse mounted thereon for shutting off power in case of over-current, the fuse device comprising: the fuse including a fuse body, connection terminals extending from one side of the fuse body to the opposite side thereof, and an electrically insulated fuse cover that encloses the fuse body; a fuse holder having a mounting indentation part formed on the front surface thereof and one or more fasteners formed on the outside of the mounting indentation part, wherein the fuse is inserted into and mounted on the mounting indentation part, and the fasteners are used to mount the fuse device on an external device in a front direction corresponding to the direction in which the fuse is inserted into and mounted on the mounting indentation part; and a pair of conductive connecting members that are embedded in the fuse holder and have a front connection part formed in the front direction and a rear connection part formed in the rear direction, wherein the connection terminals of the fuse make contact with the front connection part, and a connection member for electric connection with the external device makes contact with the rear connection part.

Description

technical field [0001] The present invention relates to a fuse device having a fuse for cutting off electric power when an overcurrent flows. Background technique [0002] In recent years, secondary batteries capable of charging and discharging have been widely used as energy sources for wireless mobile devices. In addition, secondary batteries have attracted considerable attention as power sources for electric vehicles (EV) and hybrid electric vehicles (HEV), which have been developed to solve problems caused by existing gasoline or diesel vehicles using fossil fuels. , such as air pollution. [0003] Small-sized mobile devices use one or several battery cells for each device. On the other hand, a medium-sized or large-sized device such as a vehicle uses a medium-sized or large-sized battery pack having a plurality of battery cells electrically connected to each other because of high output and Large capacity is necessary. [0004] A medium-sized or large-sized battery ...
