The second sealing plate 404 is provided with springs 406 through the mounting grooves 405. The other ends of the springs 406 are provided with clamping posts 407. On the fixing plate 401 and corresponding to the upper and lower sides, limiting holes 408 are formed.

[0031] Refer to Figures 1-4 , multiple groups of modules 2 are provided, and multiple wiring holes 3 are formed; two groups of front and rear fixing plates 401 are provided and fixedly connected to the side wall of the base 1. The second sealing plate 404 is slidably connected with the clamping post 407 through the mounting groove 405; a handle 410 is installed on the left side wall of the second sealing plate 404. Rubber gaskets 411 are installed on the first sealing plate 402 and the second sealing plate 404 through the wire passing holes 409. A sealing gasket is arranged at the bottom of the second sealing plate 404;
[0032] Among them, rubber gaskets 411 are installed on the first sealing plate 402 and the second sealing plate 404 through the wire passing holes 409, and a sealing gasket is arranged at the bottom of the second sealing plate 404. The rubber gaskets 411 can play a role in protecting the outer surface of the wire when the first sealing plate 402 and the second sealing plate 404 are connected, and at the same time, also play a sealing role in the connection between the first sealing plate 402, the second sealing plate 404 and the connected wire; the sealing gasket plays a sealing role in the connection between the first sealing plate 402 and the second sealing plate 404, preventing dust from entering the device from the connection gap;

[0036] Among them, since the sum of the areas of the first sealing plate 402 and the second sealing plate 404 is greater than the wiring hole 3, after the first sealing plate 402 and the second sealing plate 404 are connected, the covering and sealing effect on the wiring hole 3 can be achieved;
[0037] Working principle: After the wiring of the surge protector is completed, the front and rear clamping columns 407 are simultaneously pressed into the corresponding installation grooves 405. When the clamping column 407 leaves the upper limiting hole 408, the handle 410 is used to drive the second sealing plate 404 to move downward. The front and rear two clamping columns 407 move in the corresponding sliding grooves 403. When the clamping column 407 reaches the position of the lower limiting hole 408, under the reset action of the spring 406, the spring 406 pushes the clamping column 407 into the lower limiting hole 408, thereby realizing the position fixation of the second sealing plate 404. At this time, the first sealing plate 402 and the second sealing plate 404 are in contact with each other. The first sealing plate 402 and the second sealing plate 404 clamp and fit the outer wall of the butt joint wire through the corresponding rubber pads 411, realizing the sealing effect on the wiring hole 3, preventing dust from entering the device body from the wiring hole 3. By setting the dust-proof structure 4, the problem that the wiring hole 3 of the existing surge protector is exposed outside, and dust will enter the device body from the wiring hole 3, and the dust adheres to the circuit or parts, which will accelerate the aging of the circuit or parts, is solved, and the service life of the surge protector is extended;
[0038] The fan 9 works to accelerate the air flow rate inside the module 2, accelerating the internal and external air exchange of the module 2, thereby effectively dissipating heat from the module 2; the heat sink 12 dissipates heat from the outer wall of the base 1, thereby reducing the self-temperature of the base 1, achieving an effective heat dissipation effect on the base 1, and thus playing a role in dissipating heat for the overall surge protector. By setting the fan 9 and the heat sink 12, etc., the problem that the existing surge protector generates heat during operation and lacks an effective heat dissipation device, which will cause the surge protector to have an excessively high self-temperature and be damaged, is solved, the heat dissipation performance of the surge protector is improved, and thus the surge protector is protected.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
