[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides a secondary winding frame for a high-frequency high-voltage transformer, comprising an inner frame 1, an insulating plate 2 fixedly connected inside the inner frame 1, a wire group 8 fixedly connected inside the insulating plate 2, a fixing cylinder 3 fixedly connected to the outer wall of the insulating plate 2, a first spring 4 slidably connected inside the fixing cylinder 3, a limiting plate 5 fixedly connected to the outer wall of the first spring 4, the outer wall of the limiting plate 5 slidably connected to the inner wall of the fixing cylinder 3, a winding frame 6 slidably connected to the outer wall of the limiting plate 5, a groove 7 being provided inside the winding frame 6, and a support assembly provided on the outer wall of the inner frame 1 for limiting the inner frame 1.

[0025] Specifically, by pulling the winding frame 6 to slide within the fixed cylinder 3, the winding frame 6 drives the limiting plate 5 to slide within the fixed cylinder 3. The fixed cylinder 3 limits the movement of the limiting plate 5. As the limiting plate 5 slides, it compresses the first spring 4, causing it to contract. At this time, the other end of the winding frame 6 slides out from the other end of the fixed cylinder 3, thus achieving the effect of replacing the winding frame 6 as needed. The inner frame 1 supports and fixes the insulating plate 2. The conductor group 8 consists of metal pins in the frame that, after being soldered, can be connected to the PCB board and provide conductivity when the transformer is working. The inner frame 1, the insulating plate 2, and the winding frame 6 all have excellent insulation and high-temperature resistance. When a certain model of winding frame 6 malfunctions or is damaged, it is not necessary to replace the entire transformer frame; only the damaged winding frame 6 needs to be replaced. This reduces maintenance costs and improves the maintainability of the transformer.

[0026] Reference Figure 1 The support component includes an outer frame 9, the outer wall of an inner frame 1 is slidably connected to the inside of the outer frame 9, and a base plate 10 is fixedly connected to the lower surface of the outer frame 9.

[0027] Specifically, the outer frame 9 serves to support and limit the inner frame 1, while the base plate 10 serves to support and fix the outer frame 9.

[0028] Reference Figure 1 , Figure 2 and Figure 4 A first connecting cylinder 11 is fixedly connected to the inside of the base plate 10, and a second connecting cylinder 12 is slidably connected to the outer wall of the first connecting cylinder 11. A handle 13 is fixedly connected to the top of the second connecting cylinder 12, and a connecting post 14 is fixedly connected to the inside of the handle 13. A second spring 15 is slidably connected to the outer wall of the connecting post 14, and the outer wall of the second spring 15 is fixedly connected to the outer wall of the first connecting cylinder 11. The outer wall of the second spring 15 is slidably connected to the inner wall of the second connecting cylinder 12. The outer wall of the connecting post 14 is slidably connected to the inner wall of the first connecting cylinder 11, and a connecting plate 16 is fixedly connected to the bottom end of the first connecting cylinder 11. The outer wall of the connecting plate 16 is fixedly connected to the inside of the base plate 10, and a locking block 17 is slidably connected to the inside of the connecting plate 16. The outer wall of the locking block 17 is fixedly connected to the bottom end of the connecting post 14. A locking groove 18 is opened inside the connecting plate 16, and the outer wall of the locking block 17 is slidably connected to the inner wall of the locking groove 18 and the outer wall of the locking block 17 is slidably connected to the inside of the base plate 10.

[0029] Specifically, pressing and rotating the handle 13 ninety degrees causes the second connecting cylinder 12 to slide on the outer wall of the first connecting cylinder 11. The second connecting cylinder 12 then causes the connecting column 14 to slide within the first connecting cylinder 11. Simultaneously, the first connecting cylinder 11 compresses the second spring 15, causing it to contract. At this point, the locking block 17 slides in the slot 18 in the connecting plate 16, where the slot 18 serves to limit the locking block 17, thereby achieving the installation of the outer frame 9 on the base plate 10.

[0030] Working principle: When the winding frame is needed, pull the winding frame 6 to make it slide in the fixed cylinder 3. The winding frame 6 drives the limiting plate 5 to slide in the fixed cylinder 3. When the limiting plate 5 slides, it will squeeze the first spring 4 to retract. At this time, the other end of the winding frame 6 will slide out from the other end of the fixed cylinder 3, so that the winding frame 6 can be replaced as needed. Press and rotate the handle 13 ninety degrees. The handle 13 drives the second connecting cylinder 12 to slide on the outer wall of the first connecting cylinder 11. The second connecting cylinder 12 drives the connecting post 14 to slide in the first connecting cylinder 11. At the same time, through the... The first connecting cylinder 11 compresses the second spring 15, causing it to retract. At this time, the locking block 17 slides in the locking groove 18 in the connecting plate 16, thereby allowing the outer frame 9 on the base plate 10 to be installed. This winding frame not only achieves the effect of replacing different models of winding frames 6 as needed, thus adapting to different production requirements, but also ensures that the transformer can meet these diverse needs. In the manufacturing or maintenance of high-frequency high-voltage transformers, different winding configurations may need to be selected according to specific electrical performance requirements. Replacing the winding frame 6 as needed ensures that the transformer can meet these diverse requirements. Different winding frame 6 designs may have different effects on the electrical performance of the transformer. By replacing the winding frame 6, these performance parameters can be adjusted, thereby optimizing the overall performance of the transformer. It also achieves the effect of quickly installing or removing the outer frame 9, thereby simplifying the assembly and disassembly process of the transformer and shortening the production cycle.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
