DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments.

[0021] The embodiment provides a modular DC screen, and refers to Figures 1-4 Specifically, the modular DC screen comprises a cabinet body 1, a moving assembly 2, a lead adjusting assembly 3 and a high-frequency power switch module 100. The cabinet body 1 is vertically arranged with a plurality of module brackets 11. The high-frequency power switch module 100 is arranged on the module bracket 11. Fixed supports 12 are fixedly arranged at one end of the module bracket 11 close to the inside of the cabinet body 1. Plug-in terminals are arranged in the fixed supports 12 as input and output power supply external lead connection positions. The moving assembly 2 is arranged on the lower surface of the module bracket 11. The lead adjusting assembly 3 is arranged at one end of the module bracket 11 close to the inside of the cabinet body 1.

[0022] The high-frequency power switch module 100 is arranged in the module bracket 11. The plug-in terminals are fixed in the fixed supports 12. External leads pass through the cabinet body 1 and are connected with the plug-in terminals through the lead adjusting assembly 3. When overhauling, the module bracket 11 is pulled, and the module bracket 11 is moved to the outside of the cabinet body 1 through the moving assembly 2, so that the module bracket 11 is separated from the narrow space in the cabinet body 1, thereby improving the overhauling and replacing efficiency. When the module bracket 11 moves, the lead adjusting assembly 3 adjusts the length of the lead connected with the plug-in terminal, so that the lead connected with the plug-in terminal is not separated from the plug-in terminal when the position of the high-frequency power switch module 100 changes, and the stability of the module is improved.

[0023] In the specific implementation process, as shown in Figure 2 and Figure 3 , the moving assembly 2 comprises a plurality of guide rails 21 and sliding blocks 22 sliding in the guide rails 21. The guide rails 21 are fixedly connected with the inner wall of the cabinet body 1. The lower surface of the module bracket 11 is fixedly provided with two sliding blocks 22.

[0024] When the module bracket 11 moves, the sliding blocks 22 slide along the guide rails 21, so that the high-frequency power switch module 100 is conveniently moved to the outside of the cabinet body 1, and the maintenance efficiency is improved.

[0025] In the specific implementation process, as shown in Figure 3 and Figure 4 , the lead adjusting assembly 3 comprises two fixed plates 31 fixedly arranged on one side of the fixed support 12. A rotating rod 32 is rotatably arranged between the two fixed plates 31. Two connecting rods 33 are fixedly arranged on the rotating rod 32. A connecting piece 34 is rotatably arranged at one end of the connecting rod 33. Torsional springs 35 are sleeved on both ends of the rotating rod 32. One end of the torsional spring 35 is fixedly connected with one side of the connecting rod 33. The connecting piece 34 comprises two oval plates and two round rods. The inner sides of the oval plates are fixedly connected with the end portions of the two round rods. A plurality of blocking rods 4 are fixedly arranged on the inner wall of the cabinet body 1. The blocking rods 4 are in close contact with one side of the connecting rod 33.

[0026] After the lead wire is passed through the cabinet 1, it is connected with the plug-in terminal through the two round rods on the connecting piece 34, and the connecting rod 33 is twisted by the torsion spring 35 to make the connecting rod 33 and the fixed support 12 have an angle, so that the lead wire passing through the connecting piece 34 has a certain arc; when the module bracket 11 drives the fixed support 12 to move synchronously, the fixed plate 31, the rotating rod 32, the connecting rod 33 and the connecting piece 34 on the fixed support 12 move synchronously, the connecting rod 33 is blocked by the blocking rod 4, the connecting rod 33 drives the rotating rod 32 to rotate along the fixed plate 31, the connecting rod 33 is parallel to the top and bottom of the cabinet 1, and the lead wire passing through the middle of the connecting piece 34 also moves, so that the arc-shaped lead wire becomes a straight line to adapt to the moving distance of the fixed support 12; when the module bracket 11 enters the cabinet 1, the connecting rod 33 is reset by the torsion spring 35.

[0027] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
