Description
Technical field
The utility model relates to a kind of cartridge fuse, relates in particular to the emergent cartridge fuse of a kind of fuse switch.
Background technology
Fuse switch is one of a large amount of visual plants that use of distribution, and need interruption maintenance because a variety of causes causes the upper and lower contact of a large amount of fuse switches to burn out every year, influences the normal electricity consumption of power consumer.
Summary of the invention
The purpose of the utility model provides the emergent cartridge fuse of a kind of fuse switch easy to use.
Be to realize above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of fuse switch cartridge fuse of meeting an urgent need comprises insulator; The insulator lower end is fixedly connected with down fixed contact, and the insulator upper end is fixedly connected with upper static contact, it is characterized in that: the right-hand insulated tube that is designed with of insulator; The bottom of insulated tube is fixedly connected with down fixed cover, and the left surface of following fixed cover is fixedly connected with down contact, and the top of insulated tube is fixedly connected with fixed cover; The left surface of last fixed cover is fixedly connected with the upper contact head frame, and the free end of upper contact head frame is designed with hook, is fixedly connected with conductive contact below the upper contact head frame; Be fixedly connected with the contact pressure spring between upper contact head frame and the conductive contact; Be fixedly connected with the fuse spring on the upper contact head frame, fuse is housed in the insulated tube, fuse is positioned on the fuse spring; The fuse upper end is crimped on the conductive contact, and the fuse lower end is crimped on down on the contact.
The utility model has the advantages of and be: because this structure of the utility model,, use handling safety, convenience, the repairing time of conservation of power fault so when using the utility model, can under the situation that fuse switch damages, not influence power supply.
