Description

Technical Field

[0001] The utility model relates to the technical field of fuses, in particular to a fuse protection seat. Background Art

[0002] A fuse is an electrical device that uses the heat generated by itself to melt the fuse element and disconnect the circuit when the current exceeds the specified value. A fuse is a current protector made based on the principle that after the current exceeds the specified value for a period of time, the heat generated by itself will melt the fuse element and disconnect the circuit.

[0003] There is an existing fuse base for power protection (application number: 202022794254.9) which makes it convenient for staff to comb the wire body, thereby making the wire body installation more convenient and convenient for later line maintenance. The above-mentioned problem still exists. When the fuse is used, the fuse needs to be placed in the protective seat and the protective seat is connected to the external line. When the line is connected, it is often fixed by turning the fastening bolts, which is not convenient for protecting the line after connection. When the line is pulled, it is easy to cause the line and the fuse protection seat to separate and break, thereby affecting normal use. When the fuse protection seat is used, the fuse will generate a certain amount of heat, and then a heat dissipation port will be set on the left and right sides of the fuse protection seat. Due to the large size of the heat dissipation port, it is easy for impurities to enter the interior of the fuse protection seat, which is not convenient for blocking external impurities during heat dissipation. Impurities entering the fuse protection seat can easily affect use. Utility Model Content
