Problems solved by technology

[0002] The self-recovery fuse is an over-current electronic protection component. The traditional over-current protection of the fuse can only protect once. The emission is slow, resulting in a slow decrease in the internal resistance of the fuse, which affects the current on-time, and the temperature of the self-recovery fuse cannot be known when it is in use, making the staff unclear about its working status

Abstract

The invention discloses a resettable fuse, and the fuse comprises a base and a resettable fuse body; a protective cover is arranged at the top end of the base, threading openings are formed in the two sides of the protective cover, a heat dissipation opening is formed in the top end of the protective cover, a fixed plate is arranged at the top end of the base, a mounting box is mounted at the top end of the fixed plate, and jacks are formed in the two sides of the top end of the mounting box. the top end of the fixed plate is provided with a self-recovery fuse, the two sides of the self-recovery fuse are provided with heat dissipation plates, the top end of the fuse is provided with temperature measuring paper, the two sides of the installation box are provided with wire interfaces, the outer sides of the wire interfaces are provided with baffles, and the bottom end of each baffle and the top end of the fixed plate are fixedly installed. One side of the base is provided with a first connecting block, and one side of the protection cover is provided with a second connecting block. Rotating shafts are arranged on the two sides of the second connecting block, and the first connecting block and the second connecting block are rotationally connected through the rotating shafts. The resettable fuse is simple and reasonable in structure, novel in design and simple and convenient to operate, heat dissipation of the resettable fuse can be effectively achieved, temperature visualization is achieved, and the resettable fuse has a higher practical value.

Description

technical field [0001] The invention relates to the technical field of fuses, in particular to a resettable fuse. Background technique [0002] The self-recovery fuse is an over-current electronic protection component. The traditional over-current protection of the fuse can only protect once. The slow emission causes the internal resistance of the fuse to decrease slowly, which affects the current connection time, and the temperature of the self-recovery fuse cannot be known when it is used, making the staff unclear about its working status. So we improve this and propose a resettable fuse. Contents of the invention [0003] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [0004] A self-recovery fuse of the present invention comprises a base and a self-recovery fuse. A protective cover is provided at the top of the base, threading openings are opened on both sides of the protective cov...
