ことができる。 The fuse link locking device configured as described above makes it impossible to move the current limiting fuse 31, which is clamped to both the fuse clamping fittings 21 and 22, in the length direction on the fuse support base 20. Since the load-side connection terminal 30 is attached to one fuse clamp 22 and the fuse stopper 32 as a fuse link locking part is integrally formed with the fuse clamp 22, another locking member is not required. Therefore, the number of parts can be reduced, and there is no need for assembling, so manufacturing costs can be reduced.

できる特有の効果を奏する。Effects As detailed above, this invention bends the terminal side end of the load side connection terminal toward the fuse link side in an L shape, and also bends the fuse link locking portion into an L shape so that it protrudes toward the fuse link side. By punching out the shape, the current-limiting fuse is locked using the load-side connection terminal connected to the fuse clamping fitting, so there is no need to use any other member for locking the current-limiting fuse in addition to the load-side connection terminal. It is not necessary to provide a component, the number of parts can be reduced, and there is no need for assembly for that purpose, which brings about the unique effect of reducing manufacturing costs.
