A surge protector 12 is installed in the inner cavity of the main body 1 of the distribution cabinet. Example 2

[0024] Figures 1-4 This invention illustrates the structure of a surge protector for a distribution cabinet according to an embodiment of the present invention. The structure includes: a support and positioning member 2 fixedly connected to the inner cavity of the distribution cabinet body 1; a cavity support plate 3 fixedly connected to the front side of the support and positioning member 2; an abutment positioning piece 4 slidably connected to the inner cavity of the cavity support plate 3; a threaded round tube 5 communicating with the front side of the cavity support plate 3; a threaded pin 6 threadedly connected to the inner cavity of the threaded round tube 5; the rear end of the threaded pin 6 rotatably connected to the front side of the abutment positioning piece 4; and a rectangular through hole 7 on the surface of the cavity support plate 3. The surge protector 12 is located directly above the support positioning piece 2 and the cavity support plate 3. The circuit breaker 13 is installed in the inner cavity of the distribution cabinet body 1. The wire gathering piece 14 is fixedly connected to the inner cavity of the distribution cabinet body 1. The wire gathering piece 14 can be used to gather the wires in the inner cavity of the distribution cabinet body 1 when they are arranged, making the wires more neat and beautiful.

[0025] Working principle: When using this utility model, the user inserts the wire end that needs to be connected to the surge protector 12 through the inner cavity of the rectangular hole 7, and then turns the round head 10 to drive the threaded pin 6 to rotate in the inner cavity of the threaded round tube 5. At the same time, under the action of the thread of the threaded round tube 5, the contact positioning piece 4 is pushed to slide backward in the inner cavity of the cavity support plate 3, thereby pressing the wire backward. Under the elastic compression support of the auxiliary support piece 8 and the spring 9, the wire is clamped and fixed, which makes the connection between the wire and the terminal more stable and makes the wiring at the bottom of the surge protector more aesthetically pleasing.

[0026] In summary, the surge protector structure of this distribution cabinet utilizes the principle that turning the circular head 10 rotates the threaded pin 6, which in turn pushes the contact positioning plate 4 to press the wire backward. Simultaneously, under the elastic compression support of the auxiliary support plate 8 and the spring 9, the wire is clamped and fixed. This achieves the goal of fixing the position of the wire connected to the surge protector terminal, making the connection between the wire and the terminal more stable, and making the wiring at the bottom of the surge protector more aesthetically pleasing.
