What is the important role of the fuse holder?

The fuse holder is an electrical component installed in the circuit to provide insulation protection for the fuse and ensure the safe operation of the circuit. It may damage some important components or valuable components in the circuit, and may also burn the circuit or even cause a fire.

 

If the fuse sheath fuse holder is correctly placed in the circuit, then the fuse will fuse itself when the current abnormally rises to a certain height and a certain time, and a dangerous situation such as a fire may occur. At this time, the fuse holder is isolated from the outside world. , so as to protect the safe operation of the circuit.

The field of fuse holder on-board protection of passive electronic components is still relatively good, and there are still many equipment industries in which passive protection electronics are applied. Now the application range of fuse holders is also relatively wide, and in terms of technology, now fuse holders are also improved. A lot, and with the current technology and the rapid expansion of many industries in today's society, there is still a demand for fuse holders.

The fuse holder has good insulation and pressure resistance, and now the fuse holder is mainly used on the wire, such as the wire box fuse holder and the car fuse holder.

It is better for car fuse holders to be used on electric vehicle new energy vehicle equipment, and now car fuse holders are still very suitable for new energy equipment.

 

 

What does the improved structure of the fuse holder include?

The fuse holder refers to the holder used to install the fuse. The fuse holder can be divided into: panel mount fuse holder, PCB mount fuse holder, lead type fuse holder, rail type fuse holder, and automobile fuse holder.

 

The improved structure of the fuse holder, especially the fuse holder with the status of the fuse and the resettable fuse need not be replaced. It includes:

 

a first conducting body with a plurality of screw holes communicating with each other, and each screw hole is screwed into an abutting screw; a plurality of second conducting bodies with a screw hole and an insertion hole communicating with each other, each A contact screw is screwed into the screw hole; several resettable fuses are electrically connected to the first conducting body and each second conducting body;

 

A base with the first and second conductive bodies fixed on the top side; an upper cover covering the base; and a circuit board fixed on the upper cover and provided with several light-emitting components, which is connected with the The first conductive body and each of the second conductive bodies are electrically connected.
