The mounting assembly 200 also includes first mounting holes 207 arranged in the mounting plate 201, and screws 208 movably installed in the first mounting holes 207. The mounting assembly 200 also includes a notch 209 provided on one side of the mounting plate 201, and a connecting strip 210 fixedly installed at the outer end of the clamping column 205 in the notch 209.

[0026] Specifically, the AC overvoltage protector is a device for protecting electrical equipment and circuits from the influence of excessively high voltage. When installing the overvoltage protector body 100, the overvoltage protector body 100 can be first fixedly installed on a wall or in an electrical box through the mounting plate 201 at the rear end thereof, and then the overvoltage protector body 100 can be fixed in the mounting cavity 202 in the mounting plate 201 through the clamping block 203 at the rear end thereof, thereby avoiding the problem of inconvenient and quick disassembly of the overvoltage protector body 100 during maintenance or replacement. The installed clamping column 205 and spring 206 are mainly used to engage with the inside of the clamping groove 204 in the clamping block 203, so as to complete the clamping and fixing of the overvoltage protector body 100 at the front end of the mounting plate 201. The first mounting hole 207 opened in the mounting plate 201 and the screw 208 installed therein are mainly used for the installation and fixation of the mounting plate 201. The connecting strip 210 fixedly installed at the outer end of the clamping column 205 in the recess 209 is mainly used for the synchronous telescopic adjustment of the clamping columns 205 at the upper and lower ends in the mounting plate 201.

[0027] Embodiment 2:

[0028] Based on the first embodiment, Figure 2 and Figure 5As shown, a protective plate 300 is movably installed at the rear end of the mounting plate 201, and a second mounting hole 301 is arranged and penetrated in the protective plate 300, and the second mounting hole 301 has the same size as the first mounting hole 207.

[0030] The working principle and use process of this utility model:

[0031] When installing the overvoltage protector body 100, first fix the mounting plate 201 and the protective plate 300 on the wall or in the electrical box by means of the screws 208. After the mounting plate 201 is fixed, the connecting strip 210 in the notch 209 on one side of the mounting plate 201 is pulled outward. After the connecting strip 210 is pulled outward, the clamping column 205 on the inner side of the upper and lower ends of the connecting strip 210 in the mounting cavity 202 is pulled outward. When the clamping column 205 moves outward, the spring 206 at the outer end of the clamping column 205 is compressed. Therefore, after the clamping column 205 moves outward, the overvoltage protector body 100 is installed to the front end of the mounting plate 201, and the clamping blocks 203 on the upper and lower sides of the rear end of the overvoltage protector body 100 are engaged. In the mounting cavity 202 at the front end of the mounting plate 201, at this time, the outwardly pulled connecting strip 210 can be loosened, so that the clamping column 205 can be clamped into the inside of the clamping groove 204 in the clamping block 203 through the elastic force of the compression spring 206 at the upper end of the clamping column 205, thereby completing the installation and fixation of the overvoltage protector body 100 at the front end of the mounting plate 201. When the overvoltage protector body 100 is in use, the protective plate 300 installed at the rear end thereof can also perform flame retardant and waterproof isolation protection on the overvoltage protector body 100 after installation through the pearlite wool board 302, PVC board 303 and waterproof membrane 304 therein, thereby improving the safety of the overvoltage protector body 100 in use.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
