Description

Technical Field

[0001] This utility model belongs to the field of overvoltage protectors, and in particular relates to an installation structure for an overvoltage protector. Background Technology

[0002] In modern power systems, overvoltage is a common cause of electrical equipment damage and safety accidents. Overvoltage can be caused by various factors, including lightning strikes, switch operation, and power system faults. When overvoltage exceeds the rated voltage of electrical equipment, it can lead to serious consequences such as insulation breakdown, equipment damage, and even fires. Therefore, overvoltage protectors are typically installed inside electrical equipment.

[0003] However, existing overvoltage protectors still have certain drawbacks. For example, overvoltage protectors are usually mounted on a mounting plate with multiple screws, which means that tools such as screwdrivers are needed to install and remove the overvoltage protector. Each screw needs to be tightened or loosened individually, which is cumbersome and affects work efficiency. Utility Model Content

[0028] Specific embodiment one is as follows Figures 1-5 As shown, this utility model is an installation structure for an overvoltage protector, including an overvoltage protector body 1 and a snap-fit ​​assembly 5 fixedly connected to the upper surface of the overvoltage protector body 1.

[0029] like Figures 1-4 As shown, the overvoltage protector body 1 has a positioning block 2 fixedly connected to the lower surface of the overvoltage protector body 1, a mounting plate 3 set on the rear surface of the overvoltage protector body 1, and a positioning frame 4 fixedly connected to the front surface of the mounting plate 3. The inner surface of the positioning frame 4 is provided with a positioning hole 18 that matches the positioning block 2.

[0030] In this embodiment, when installing the overvoltage protector body 1, simply align the positioning block 2 below the overvoltage protector body 1 with the positioning hole 18 inside the positioning frame 4, and then snap the positioning block 2 into the connecting cylinder 16 to quickly complete the installation and positioning of the positioning block 2, thereby improving the installation speed.

[0031] Specific embodiment two is as follows Figures 1-5 As shown, this utility model is an installation structure for an overvoltage protector. Compared with Embodiment 1, in this embodiment, the snap-fit ​​assembly 5, which is fixedly connected to the upper surface of the overvoltage protector body 1, includes a fixing box 6 fixedly connected to the upper surface of the overvoltage protector body 1, a first insert block 7 slidably connected to the inner surface of the fixing box 6, a first toothed plate 8 fixedly connected to the lower surface of the first insert block 7, a first spring 9 fixedly connected to the right end of the first toothed plate 8, a second insert block 10 slidably connected to the inner surface of the fixing box 6, a second toothed plate 11 fixedly connected to the upper surface of the second insert block 10, a second spring 12 fixedly connected to the left end of the second toothed plate 11, a connecting shaft 13 rotatably connected to the inner surface of the fixing box 6, a gear 14 fixedly connected to the outer surface of the connecting shaft 13, a fixing block 15 fixedly connected to the outer surface of the connecting shaft 13, and a connecting sleeve 1 fixedly connected to the outer surface of the fixing block 15. 6. A pin 17 is movably connected to the inner surface of the connecting tube frame 16. The outer surface of the positioning frame 4 has a first insertion hole 19 that matches the first insertion block 7. The outer surface of the positioning frame 4 has a second insertion hole 20 that matches the second insertion block 10. The front surface of the fixing box 6 has a limiting hole 21 that matches the pin 17. The number of limiting holes 21 is multiple and they are distributed in a circular array. The outer surface of the overvoltage protector body 1 is in contact with the positioning frame 4. The rear surface of the fixing box 6 is in contact with the mounting plate 3. The first toothed plate 8 meshes with the gear 14. The second toothed plate 11 meshes with the gear 14. The end of the first spring 9 away from the first toothed plate 8 is fixedly connected to the fixing box 6. The end of the second spring 12 away from the second toothed plate 11 is fixedly connected to the fixing box 6. The upper surface of the first insertion block 7 is in contact with the second toothed plate 11. The lower surface of the second insertion block 10 is in contact with the first toothed plate 8.

[0032] In this embodiment, before installing the overvoltage protector body 1, the pin 17 inside the connecting sleeve 16 is pulled out, causing the pin 17 to disengage from the limiting hole 21. Then, the fixing block 15 is rotated, driving the connecting shaft 13 to drive the gear 14 to rotate. At this time, under the meshing action of the first toothed plate 8 and the gear 14, and the second toothed plate 11 and the gear 14, the first insert 7 and the second insert 10 will be driven to retract into the fixing box 6 respectively, and the first spring 9 and the second spring 12 will be compressed at the same time. Then, the pin 17 is reinserted into the corresponding limiting hole 21, which can limit and fix the first insert 7 and the second insert 10 in the retracted state. Then, according to the above positioning and installation steps, the positioning block 2 below the overvoltage protector body 1 is inserted into the positioning hole 18. When the positioning block 2 is fully inserted into the positioning hole 18, the positioning block 2 is inserted into the positioning hole 18. After the first insertion block 7 and the second insertion block 10 are inserted into the positioning hole 18, they correspond to the first insertion hole 19 and the second insertion hole 20, respectively. At this time, the pin 17 inside the limiting hole 21 is pulled out. Under the restoring force of the first spring 9 and the second spring 12, the first insertion block 7 and the second insertion block 10 will automatically snap into the first insertion block 7 and the second insertion block 10, respectively, thus completing the limiting and fixing installation of the overvoltage protector body 1. When it is necessary to disassemble and repair the overvoltage protector body 1, simply rotate the fixing block 15 again to drive the first insertion block 7 and the second insertion block 10 out of the first insertion hole 19 and the second insertion hole 20, and snap the pin 17 into the corresponding limiting hole 21. Then, pull the overvoltage protector body 1 upward along the inside of the positioning frame 4 to complete the disassembly. It is simple and convenient and does not require tools.
