Description

Technical Field

[0001] The utility model relates to the technical field of fuse tooling, in particular to a fuse tooling without a housing. Background Art

[0002] In the field of circuit protection, the design of fuses is of vital importance. Since the shell of the fuse will limit the dissipation of heat, reduce the heat dissipation efficiency, and affect the normal operation and life of the fuse, especially in flammable and explosive environments, it is easy to increase safety risks due to heat dissipation problems. In addition, compared with fuses with shells, fuses without shells can further reduce the size of the fuse, reduce the weight of the fuse, and reduce manufacturing costs. They have the advantages of fast response speed, easy observation, flexible adjustment according to needs, more environmental protection, simplified installation, and strong adaptability. Therefore, based on the purpose of providing a sufficiently powerful fuse for the fuse, the double shell will affect the heat dissipation, and removing some shells can fill more arc extinguishing materials (such as quartz sand), the shell-less fuse has been developed. However, the existing shell-less fuses have caused certain difficulties in production due to the characteristics of being difficult to shape without a shell and difficult to demold after shaping.
