In the process of using the fuse holder, it is mainly used to install the fuse holder or guard. Mostly used for the connection of small home appliances and industrial machinery wiring harness), PCB fuse holder (mostly used on small home appliance control boards) and fuse clips (mostly used on small home appliance control boards). Car fuse holders can be divided into lead-type car fuse holders (used in automobiles and industrial machinery wiring harnesses), panel mounted car fuse holders (used in car electrical appliances, such as car amplifiers, car refrigerators, car DVDs, etc.) and car fuse clips.​​

Fuse holders can be divided into: panel device fuse holders, PCB device fuse holders, lead fuse holders and car fuse holders; panel device fuse holders (mostly used for electrical equipment, such as power amplifiers, DVDs, speakers, massage chairs and other electrical equipment) ; Lead type fuse holder (used for connection of small household appliances and industrial machinery wiring harness), PCB fuse holder (used for control panel of small household electrical appliance) and fuse clip (used for control panel of small household electrical appliance).​​

Car fuse holders can be divided into lead-type car fuse holders (used in automobiles and industrial machinery wiring harnesses), panel mounted car fuse holders (used in car electrical appliances, such as car amplifiers, car refrigerators, car DVDs, etc.) and car fuse clips. The fuse holder has the requirements of withstand current, withstand voltage, and fire rating. Generally, it needs to pass the safety regulations such as ULCSAVDEROHS and EU certification.​​

The improved structure of the fuse holder, to a certain extent, mainly refers to the fuse holder that has the condition of showing the fuse and does not need to replace its resettable fuse. It includes: a first conducting body with a plurality of screw holes communicating with each other, each screw hole is screwed into an abutting screw; a plurality of second conducting bodies with a screw hole and a jack that communicate with each other , each screw hole is screwed into a contact screw, and several are connected to the resettable fuse between the first conducting body and each second conducting body in an electrical connection way, and the first and second conducting bodies are fixed on one top side. The base of the conducting body; an upper cover covering the base; and a circuit board fixed on the upper cover and provided with a plurality of light-emitting components, which is connected with the first conducting body and each second conducting body The body forms an electrical connection.
