[0017] The following will be described in detail in combination with the accompanying Figure 1 - Figure 4 The present application is further described in detail.

[0018] Embodiment I:

[0019] The overvoltage protector, referring to Figure 1 - Figure 4, including the mounting seat 1, the surface of the mounting seat 1 is fixedly connected with the frame-shaped plate 2, the inner walls of two opposite shorter edges of the frame-shaped plate 2 are threadedly connected with the screw rod 3, one end of the screw rod 3 located inside the frame-shaped plate 2 is rotatably connected with the clamping plate 4, the outer walls of two opposite longer edges of the frame-shaped plate 2 are provided with the clamping groove 5, the interiors of the two clamping grooves 5 are jointly provided with the U-shaped fixing plate 6, the bottom of the mounting seat 1 is provided with the rubber suction cup 7 at four corners, the mounting seat 1 serves as the basic support structure of the whole overvoltage protector and provides a mounting and bearing platform for the frame-shaped plate 2 and other components, the mounting seat 1 can be adsorbed on the required mounting surface through the rubber suction cup 7 at the bottom thereof, and the working principle is that the air in the rubber suction cup 7 is extruded when the mounting seat 1 is pressed on the flat surface, and the external atmospheric pressure tightly presses it on the surface, so that adsorption and fixation are realized. Meanwhile, the frame-shaped plate 2 is fixedly connected on the surface of the mounting seat 1 and forms a frame structure for mounting and fixing the protector body 8, the shape and size of the frame-shaped plate 2 are designed to accommodate the protector body 8 and position and clamp the protector body 8 through subsequent components, when the protector body 8 is placed in the frame-shaped plate 2, the U-shaped fixing plate 6 is clamped into the clamping groove 5, and the working principle is that the cooperation of the clamping groove 5 and the U-shaped fixing plate 6 limits the vertical movement of the protector body 8. The U-shaped fixing plate 6 limits the protector body 8 from upward movement from above, and meanwhile, combined with the horizontal clamping force of the clamping plate 4, three-dimensional space positioning and fixation of the protector body 8 are realized, so that the position of the protector body 8 in the frame-shaped plate 2 is stable.

[0020] With reference to Figure 1 The protector body 8 is placed on the surface of the mounting seat 1 and between the two frame-shaped plates 2, the protector body 8 placed between the two frame-shaped plates 2 on the surface of the mounting seat 1 is the core part of the whole overvoltage protector and is responsible for monitoring and protecting overvoltage, it is surrounded and fixed by the frame-shaped plate 2, the clamping plate 4, the U-shaped fixing plate 6 and other components, so as to ensure that it is in a stable position when working and will not displace or loosen due to external vibration, impact or other external force, and the function of overvoltage protection in the electrical system can be normally played.

[0021] With reference to Figure 1 and Figure 4The opposite side of the two clamping plates 4 is provided with rubber pads 9. The rubber pads 9 provided on the opposite side of the two clamping plates 4 can play a buffering role. When the screw rod 3 rotates to drive the clamping plate 4 to clamp the protector body 8, the rubber pads 9 can avoid the direct rigid contact of the clamping plate 4 with the protector body 8, prevent scratching and extrusion damage to the surface of the protector body 8, and protect the appearance and internal structure of the protector body 8. On the other hand, the rubber pads 9 have a large friction coefficient, which can increase the friction between the rubber pads 9 and the protector body 8 after clamping, enhance the clamping effect of the clamping plate 4 on the protector body 8, further improve the stability of the protector body 8 in the frame-shaped plate 2, prevent relative sliding of the protector body 8 during work due to various reasons, and ensure that the protector body 8 is firmly fixed at the installation position to ensure the stability and reliability of the overvoltage protection function.

[0022] With reference to Figure 3 and Figure 4 , the inside of the frame-shaped plate 2 and on both sides of the protector body 8 are fixedly connected with limiting rods 10. The two limiting rods 10 are slidably connected with the two clamping plates 4. The main function of the limiting rod 10 is to provide guidance and limiting for the linear motion of the clamping plate 4. When the screw rod 3 rotates to drive the clamping plate 4 to move, the clamping plate 4 slides along the limiting rod 10, which ensures that the clamping plate 4 can only move in the predetermined linear direction, prevents deviation or rotation, and ensures the accuracy and stability of the movement of the clamping plate 4.

[0023] With reference to Figure 2 , the bottom of the mounting seat 1 is fixedly connected with two positioning rods 11. The two positioning rods 11 fixedly connected to the bottom of the mounting seat 1 are used to cooperate with the corresponding positioning holes or positioning structures on the electrical equipment. When the overvoltage protector is installed on the electrical equipment, the positioning rod 11 can be inserted into the positioning hole pre-set on the electrical equipment to play a pre-positioning role, so that the entire overvoltage protector can be accurately installed at the predetermined position.

[0024] The implementation principle of the overvoltage protector in the embodiments of the present application is as follows: the mounting base 1 can be adsorbed on a required mounting surface through the rubber suction cup 7 at the bottom thereof, and the elastic deformation of the rubber suction cup 7 is utilized, when the mounting base 1 is pressed on a flat surface, the air in the rubber suction cup 7 is extruded, and the external atmospheric pressure tightly presses it on the surface, so that adsorption and fixation are achieved, when the overvoltage protector is installed on an electrical device, the positioning rod 11 can be inserted into a positioning hole pre-provided on the electrical device, so as to play a role of pre-positioning, so that the entire overvoltage protector can be accurately installed at a predetermined position, meanwhile, the frame-shaped plate 2 is fixedly connected on the surface of the mounting base 1, so as to form a frame structure for installing and fixing the protector body 8, the shape and size of the frame-shaped plate 2 are designed to be capable of accommodating the protector body 8, and the protector body 8 is positioned and clamped by subsequent components, after the protector body 8 is placed in the frame-shaped plate 2, the rubber pads 9 provided on the opposite sides of the two clamping plates 4 play the following two roles: on the one hand, the rubber pads 9 play a buffering role, when the screw rod 3 rotates to drive the clamping plates 4 to clamp the protector body 8, when the screw rod 3 rotates to drive the clamping plates 4 to move, the clamping plates 4 slide along the limiting rods 10, so as to ensure that the clamping plates 4 can only move along a predetermined straight line direction, so as to prevent the clamping plates 4 from deviating or rotating, and ensure the accuracy and stability of the movement of the clamping plates 4, the rubber pads 9 can avoid the rigid contact of the clamping plates 4 with the protector body 8, so as to prevent scratches and extrusion damage to the surface of the protector body 8, and protect the appearance and internal structure of the protector body 8; on the other hand, the rubber pads 9 have a large friction coefficient, after clamping, the rubber pads 9 can increase the friction between the clamping plates 4 and the protector body 8, so as to enhance the clamping effect of the clamping plates 4 on the protector body 8, and further improve the stability of the protector body 8 in the frame-shaped plate 2, so as to prevent the protector body 8 from relatively sliding due to various reasons in the working process, and ensure that the protector body 8 is firmly fixed at the mounting position, so as to ensure the stability and reliability of the overvoltage protection function, the U-shaped fixing plate 6 is clamped into the clamping groove 5, through the cooperation of the clamping groove 5 and the U-shaped fixing plate 6, the movement of the protector body 8 in the vertical direction is limited, the U-shaped fixing plate 6 limits the protector body 8 from upward movement from above, meanwhile, in combination with the horizontal clamping force of the clamping plates 4, the three-dimensional space positioning and fixation of the protector body 8 are realized, and the position stability of the protector body 8 in the frame-shaped plate 2 is ensured.
