[0055] Example 3:
[0056] Based on Embodiments 1 and 2, in order to ensure the stability of the fuse protector body 1 within the upper housing 102 and the lower housing 101, a fixing mechanism is arranged. The fixing mechanism includes a pressure plate 301 arranged within the upper housing 102 for pressing the fuse protector body 1.
[0057] In a preferred embodiment, the fixing mechanism further includes: a connecting plate 302, fixedly connected to the top of the pressure plate 301 for driving the pressure plate 301 to press the lower housing 101; a sliding column 303, fixedly connected to the top of the connecting plate 302; a rotating handle 304, rotatably connected to the top of the sliding column 303 for fixing the sliding column 303; a limiting groove 305, fixedly connected to the top of the upper housing 102 for placing the rotating handle 304; a baffle 306, slidably connected in the limiting groove 305 for limiting the rotating handle 304; and a circular hole 307 arranged on the circular hole 307 for allowing the wiring terminals of the fuse protector body 1 to pass through.

[0059] It should be noted that the size of the round hole 307 is the same as that of the through hole 104 and their positions correspond. When the pressure plate 301 is attached to the top of the fuse protector body 1, the position of the handle 304 corresponds to the groove on the limiting groove 305. The baffle 306 is L-shaped, and a rubber protective block is provided at the bottom of the pressure plate 301.
[0060] The operating steps are as follows: The operator places the fuse protector body 1 into the lower housing 101, and ensures that the terminal at the lower end of the fuse protector body 1 passes through the through hole 104 on the lower housing 101. Then, the rubber strip 105 below the upper housing 102 is inserted into the slot 106 on the lower housing 101. At this time, the terminal at the top of the fuse protector body 1 passes through the through hole 104 on the upper housing 102 and the round hole 307 on the pressure plate 301, and the first connecting block 203 and the second connecting block 204 are in a horizontal state. The two sets of plug rods 201 are inserted into the two sets of first connecting blocks 203 in sequence, and the second connecting block 204 is inserted into the threaded structure 202. When connecting block 204, the screwdriver is used to rotate the insert rod 201 to drive the threaded structure 202 into the second connecting block 204, thereby fixing the lower housing 101 and the upper housing 102. Finally, the two sets of sliding columns 303 are pressed, and the connecting plate 302 drives the pressure plate 301 to press the top of the fuse protector body 1. When pressing down the sliding column 303, it is necessary to misalign the handle 304 with the limiting groove 305. Then, the baffle 306 is pulled to slide upward, and then the handle 304 is rotated into the limiting groove 305. The limiting groove 305 is released to limit the handle 304, so that the pressure plate 301 can press the top of the fuse protector body 1.
