Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fuses, in particular to a slow-blow fuse seat assembly. Background Art
[0002] Fuse is also called current fuse. IEC127 standard defines it as fuse-link, which mainly plays the role of overload protection. If the fuse is correctly placed in the circuit, the fuse will melt and cut off the current when the current abnormally rises to a certain height and temperature, thus protecting the safe operation of the circuit.
[0003] The existing slow-blow fuse holder assembly is not convenient for fixing the connecting wires during use. Even if it is used, it is only fixed in one position, which makes the connecting wires easily unstable, thereby reducing the efficiency of the device. Moreover, when the internal temperature is too high, it can only be detected by power off, and the internal temperature cannot be detected, which easily wastes materials. Therefore, the utility model provides a slow-blow fuse holder assembly. Utility Model Content
