Emergency protection circuit device with replaceable fuse

Abstract

The invention provides an emergency protection circuit device with a replaceable fuse, and relates to the technical field of circuit emergency protection, the emergency protection circuit device comprises a device bottom plate, a connecting cavity comprises a connecting cavity shell and terminal connecting wires, and the connecting cavity shell is internally provided with two terminal connecting wires. The fuse popping assembly comprises a popping assembly shell, a popping handle sliding groove, a fuse popping groove, a popping driving bolt and a pulling bolt handle, according to the scheme, the fuse storage box containing a plurality of fuses is inserted into the fuse popping assembly in advance, when the fuses are damaged, the fuses are moved towards one side, and the fuses are popped out through the popping handle sliding groove; when the fuse pop-up baffle abuts against the pop-up force-borrowing block, the pop-up driving block still moves, so that the fuse pop-up baffle is forced to take the top end of the pop-up force-borrowing block as a fulcrum to enable the other end of the fuse to tilt up, at the moment, the pull plug pop-up groove coincides with the fuse pop-up groove, the fuse is popped up from the pull plug pop-up groove, the damaged fuse is popped up, direct contact of personnel is not needed, and the safety is improved. And compared with the existing structure, the structure is very safe.

Description

technical field [0001] The invention relates to the technical field of circuit emergency protection, in particular to an emergency protection circuit device with a replaceable fuse. Background technique [0002] The fuse is also known as a current fuse. When the current abnormally rises to a certain height and heat, the fuse can fuse itself to cut off the current, thereby protecting the safe operation of the circuit. The fuse invented by Edison more than a hundred years ago was used to protect the expensive incandescent lamps at that time. With the development of the times, the fuse protects the electrical equipment from overcurrent and overheating, and avoids the serious damage caused by the internal failure of the electronic equipment. For example, an easy-to-replace circuit emergency protection device with application number CN202020892449.4 includes a device shell, wires and a circuit emergency protection device body. The device shell is provided with a circuit emergency...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an emergency protection circuit device with a replaceable fuse, which solves the problem of manually removing the damaged fuse and manually installing a new fuse into the circuit when replacing the fuse. During the manual replacement of the fuse, it may connect itself to a high-voltage electric field and put itself in a dangerous environment, which is very unsafe.
