Fuse is an electrical appliance that plays a role in safety protection. It can be used for isolation protection between power supply and load. It is also widely used for the protection of power grid and electrical equipment. When short circuit or overload occurs in the line of electrical grid or electrical equipment, The fuse can automatically cut off the circuit to avoid damage to the electrical equipment and prevent the accident from spreading; the existing fuse is generally inserted into the housing vertically after the melt is installed and the fuse is installed. When the fuse is replaced, the fuse is also pulled out vertically However, the existing shell structure has the disadvantages of unsmooth insertion and removal of the melt carrier and poor alignment.
In order to overcome the deficiencies of the background art, the utility model provides a fuse and its base with smooth operation and simple structure.
The technical scheme adopted by the utility model: a base of a fuse, including a shell, a melting core and a melt-carrying body which can be pulled out and inserted back in the shell, and the inner walls on both sides of the shell are provided with vertical settings The first sliding groove, the top of the first sliding groove is provided with a circular groove, and the rear end of the bottom of the melt-bearing body is provided with a sliding groove installed in the first sliding groove on both sides and adapted to the circular groove , The front end of the bottom of the melt carrying body is provided with a guide block, and a first guide groove is provided in the housing at a position corresponding to the front end of the bottom of the carrying melt body.
The melt-carrying body is provided with a melt core placement position, and the melt core placement position is composed of a plurality of fences surrounding the circumference surface of the melt core and pillars that are in contact with the bottom end of the melt core.
The fence has at least two groups a
