Fuse capable of being automatically recovered

Abstract

The invention discloses a fuse capable of being automatically recovered, which comprises a shell. A first wiring port and a second wiring port are formed in the upper end and the side wall of one sideof the shell correspondingly. A mounting opening is formed in the bottom end of the shell. The mounting opening is in threaded connection with a bottom plate. A bearing is arranged on the side wall of the center of the bottom plate. A rotating rod which is vertically arranged is fixedly inserted into the inner ring of the bearing. A rotating block is arranged at the end, away from the bottom plate, of the rotating rod. The rotating block is of a hollow structure. A fixing rod is arranged on the inner wall of the bottom end of the rotating block. A plurality of sleeves are arranged on the sidewall of the outer side of the fixing rod in a surrounding and arrayed mode. Fuse wires are arranged in the sleeves. A plurality of metal contacts are arranged on the side wall of the outer side of the rotating block in a surrounding and arrayed mode. The fuse wires in the sleeves are electrically connected with the metal contacts. According to the invention, the fuse can automatically recover theconduction of a circuit after the breaking of an overload circuit. The frequent replacement of the fuse or fuse wires is avoided, thereby bringing great convenience to users.

Description

Technical field [0001] The invention relates to the technical field of circuit protection equipment, and in particular to a fuse that can be automatically restored. Background technique [0002] A fuse is an electrical appliance that uses the heat generated by itself to fuse the melt and disconnect the circuit when the current exceeds the specified value. However, in general, when there is a thunder or an overpowered electrical appliance, the overload is too large and the input current suddenly increases, which causes the fuse to be instantly disconnected by heating, resulting in an open circuit. [0003] However, because the current is suddenly unstable, it will also cause the fuse to disconnect the line. The user needs to replace the fuse before continuing to use it. However, the user's frequent replacement of the fuse is relatively cumbersome and causes great inconvenience to the user. [0004] For this reason, we propose a fuse that can automatically recover to solve the above p...

However, in general, when there is a thunderstorm or an electrical appliance with excessive power is connected, the overload is too large, and the input current suddenly increases, which will cause the fuse to be disconnected instantaneously when heated, resulting in an open circuit

[0003] However, due to the sudden instability of the current, the fuse will also disconnect the line, and the user needs to replace the fuse before continuing to use it. However, the operation of frequently replacing the fuse is cumbersome, causing great inconvenience to the user
