Embodiment
[0014] Such as figure 1 , figure 2 As shown, this embodiment provides a new type of outdoor high-voltage drop-out fuse, which includes a fuse holder 1, a fuse carrier 3 and a lever mechanism 4, and is characterized in that the fuse holder 1 is set on the fuse holder 1 through a locking shaft pin 5. There is a locking device 2, the locking device 2 is composed of a locking plate 21 and a locking plate elastic piece 22, the locking plate 21 and the locking plate elastic piece 22 are fixedly connected, and a locking shaft pin hole 23 is provided on the locking plate 21 , the lever mechanism 4 is fixed on the fuse-carrying part 3 through a lever shaft pin 6, and the locking device 2 realizes the pressure increase and release of the contact between the fuse holder 1 and the fuse-carrying part 3 through the lever mechanism 4. The lever mechanism 4 and the locking device 2 ensure good electrical contact of the assembled fuse holder 1 and fuse carrier 3 .
