Abstract

The invention relates to the technical field of a fuse, and provides a thermal fuse and an anti-thunder element. The thermal fuse comprises a shell, a first electrode part and a second electrode part;the first electrode part and the second electrode part are inserted into the shell from the same end part of the shell at intervals; the first electrode part is elastic, and the first electrode partis pressed to be bent towards the second electrode part to prop against the second electrode part, and the propping position of the two electrode parts is welded and connected through alloy solderingtin; an accommodating space is formed in the shell; the first electrode springs back to the initial position after the alloy soldering tin is molten to form a fracture surface distance L from the second electrode part; the propping position of the first electrode parts and the second electrode parts is only welded by a little alloy soldering tin, so that a phenomenon of molten tin liquid splashingdoes not occur easily; the first electrode part is elastic and can spring back quickly in a direction deviated from the second electrode part after the soldering tin is molten, so that the break timeof the two parts is greatly shortened, thereby reducing arcing energy; and the fracture surface distance L can be preset so as to ensure the electrical insulation intensity of the fracture surface.

Description

technical field [0001] The invention relates to the technical field of fuses, and in particular provides a thermal fuse and a lightning protection element with the thermal fuse. Background technique [0002] The thermal fuse is a widely used overheating protection element. It is often used in electrical appliances with heating functions or high-temperature heat sources as the last line of defense for temperature protection. When the electronic temperature control system fails and the temperature of the high-temperature components is out of control, the power supply of the electrical appliance is cut off in time. Prevent the occurrence of fire situations. Common thermal fuses include organic thermal fuses and fusible alloy thermal fuses, among which fusible alloy thermal fuses can be further divided into axial tubular thermal fuses and radial block thermal fuses. Fusible alloy type temperature fuse relies on the capillary action of tin liquid after the alloy tin bar is melte...
