The fuse holder is an electrical component installed in the circuit, which can provide insulation protection for the fuse and ensure the safe operation of the circuit. The function of the fuse holder is that when the circuit fails or is abnormal, the current will continue to increase, and when the increased current may damage some important or valuable equipment in the circuit, or may burn the circuit or even cause the circuit to be damaged, it will cause a fire Play a certain protective role from time to time. If the fuse sheath and fuse holder are correctly placed in the circuit, the fuse will blow by itself when the current is abnormally increased to a certain height for a certain period of time to prevent dangerous situations such as fire. The seat plays the role of isolating the outside world, thus playing an important role in the safe operation of the protection circuit. Fuse holders are better in the field of passive electronic components on the protection board. There are still many equipment industries that use passive protection of electronic equipment, and the application range of fuse holders is also very wide. Block technology has also made great progress. Now, with the advancement of technology, many related industries in the society are developing rapidly, and the demand for fuse holders is also high.

The fuse holder has good insulation, pressure resistance and stability. Now, fuse holders are especially used for wire materials, such as cable box fuse holders and automobile fuse holders. It is best to use car fuse boxes for new energy vehicle equipment for electric vehicles, and now car fuse boxes are still very suitable for new energy equipment.
