Description

Fuse indicating device of fuse Technical Field The utility model relates to the technical field of fuses, in particular to a fusing indicating device of a fuse. Background A fuse is a critical electrical safety device that uses a metal conductor as a melt in series in an electrical circuit. When overload or short-circuit current passes through the melt, the melt heats itself to melt, thereby breaking the circuit. When abnormal conditions such as overload or short circuit occur, the fuse can rapidly cut off the circuit, so that the fault is prevented from being further expanded, damage to electrical equipment connected in the circuit is avoided, dangerous conditions such as fire disaster caused by electrical faults are reduced, and risk of injury to personnel is reduced. For example, in household electricity, if the electric wire has faults such as short circuit, the fuse is timely fused, so that electric shock and fire accidents can be avoided. The common fuse needs to be installed in the insulating shell for use, after fusing, the fuse in the interior can be replaced for reuse, but before replacing, a universal meter is needed to be used for checking, so that the fuse is in a normal state, the replacing time can be increased in the checking process, and the replacing efficiency is reduced. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a fusing indicating device of a fuse, which has the advantages of displaying whether a replacement core of the fuse is fused or not, and the like, and solves the problems that before replacement, a universal meter is required to be used for checking, the fuse is ensured to be in a normal state, the replacement time is increased in the checking process, and the replacement efficiency is reduced. The fuse indicating device comprises a fuse shell and a fuse wire positioned in the fuse shell, wherein an indicating spring is fixedly arranged on the inner side wall of the fuse shell, an indicating pulling plate is fixedly arranged at one end of the indicating spring, a metal base plate is fixedly arranged at one side of the indicating pulling plate, the metal base plate is in contact with one side of the fuse wire, an indicating rod penetrates through one side of the fuse shell, an indicating end plate is fixedly arranged at one end of the indicating rod, and the indicating end plate is positioned at one side, far away from the metal base plate, of the fuse wire. Further, the number of the indicating springs is four, the four indicating springs are uniformly distributed at four corners of the indicating pulling plate, and the four indicating springs are staggered with the fuse. Further, the surface cover of the indication rod is provided with a limit spring, one end of the limit spring is fixedly arranged on the inner side wall of the fuse shell, and the other end of the limit spring is contacted with one side of the indication end plate. Further, an installation base is fixedly installed on the inner bottom wall of the fuse shell, and a communicating bottom rod is fixedly installed on the top of the installation base. Further, the bottom of the fuse shell is fixedly provided with a bottom conductive terminal, and the bottom conductive terminal is communicated with the mounting base. Further, an installation top seat is fixedly arranged on the inner top wall of the fuse shell, and a communicating ejector rod is fixedly arranged at the bottom of the installation top seat.
