Description

Fuse box with fuse fusing reminding function

Technical Field

The invention belongs to the field of fuses, and particularly relates to a fuse box with a fuse fusing reminding function.

Background

When a circuit is in fault or abnormal, the current is increased continuously, and the increased current may damage some important devices in the circuit and may burn the circuit or even cause fire; if the fuse is correctly arranged in the circuit, the fuse can be fused to cut off the current when the current is abnormally increased to a certain height and heat, so that the effect of protecting the safe operation of the circuit is achieved;

the fuse is a device for protecting the cable, and can be fused when the cable is short-circuited or the current is overloaded;

many automobile electrical faults are caused by the fact that fuses are blown, for example: the fuse of the automobile headlamp is fused, but a user cannot know the fuse when the fuse is not opened in the daytime, and the user can find a fault when driving at night, so that a great amount of maintenance time for the automobile headlamp can be delayed.
