As a key component for power conversion and transmission, the performance of transformers directly affects the operational stability and efficiency of the entire electronic system.

[0003] In the field of traditional transformer technology, the structure of common wound transformers is relatively simple. For the installation requirements of multi-stage coils, a fixed architectural mode is often used, and the supporting components lack flexibility. It is not easy to adjust the distance between the top block and the bottom plate, resulting in extremely poor adaptability when facing different stages of coils. At the same time, traditional transformers mostly adopt a method of assembling after decentralized winding, which results in complex and obstructed heat dissipation paths and low heat conduction efficiency between components. Especially during high-power operation, heat accumulation is serious, further reducing the working efficiency. In order to address this technical problem, this application proposes a planar transformer with a multilayer assembly. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Referring to Figures 1-3, one embodiment of this utility model provides: a stacked flat plate transformer, including a base plate 1, a connecting circuit board 3 fixedly connected to the outer wall of the base plate 1, a side shell 2 fixedly connected to the top side of the base plate 1, a top block 4 slidably connected to the inner wall of the side shell 2, a sliding shaft 14 fixedly connected to the bottom inner wall of the side shell 2, and a sliding shell 13 fixedly connected to the bottom side of the top block 4. The outer wall of shaft 14 is slidably connected to sliders 12. A support shaft 15 is rotatably connected to the bottom side of the upper slider 12, and a support shaft 16 is rotatably connected to the top side of the lower slider 12. The middle ends of support shaft 16 and support shaft 15 are rotatably connected. The bottom end of support shaft 15 is rotatably connected to the rear end of the top side of the slider 14, and the top end of support shaft 16 is rotatably connected to the rear end of the bottom side of the sliding shell 13 to control the lifting and lowering of the slider 14. A threaded rod 17 is rotatably connected to the inner wall of the sliding shell 13. The upper slider 12 is threadedly connected to the outer wall of the threaded rod 17. A rotating block 9 is fixedly connected to the front end of the threaded rod 17 to control the movement of the slider 12. A coil 6 is installed inside the top block 4. A connecting wire 7 is installed on the outer wall of the coil 6. A connector 8 is installed at the bottom end of the connecting wire 7. The connector 8 is located on the top side of the connecting circuit board 3 for connection between the coil 6 and the connecting circuit board 3. A connecting copper sheet 10 is provided on the front side, and two adjacent connecting copper sheets 10 are connected by copper sheets. Specifically, by rotating the rotating block 9, the rotation of the threaded rod 17 can be controlled, which in turn drives the upper slider 12 to move on the outer wall of the sliding shell 13, thereby achieving rotational control of the support shaft 15. The rotation of the support shaft 15 will drive the second support shaft 16 to rotate, which in turn controls the movement of the lower slider 12, ultimately achieving movement control of the sliding shaft 14. In this way, the distance between the top block 4 and the base plate 1 can be adjusted. During installation, the required number of coils 6 are placed between the base plate 1 and the top block 4, and an insulating plate 5 is placed between two adjacent coils 6 to achieve isolation. At the same time, multiple connecting wires 7 are connected to the top side of the connecting circuit board 3, and the connecting wires 7 are fixed by the connector 8. Since the distance between the top block 4 and the base plate 1 is adjustable, it can better accommodate the installation of coils 6 of different grades. In addition, the connecting copper sheets 10 on the front side of multiple coils 6 are interconnected by copper sheets. The coils 6 adopt a film-wrapped wire integrated winding and copper sheet stacking assembly, which has a unique structural design, increases the secondary area, has better heat dissipation performance, and higher working efficiency.

[0019] Reference Figures 2-4 The outer wall of the coil 6 is provided with an insulating plate 5, the outer wall of the side shell 2 is provided with an inner plate 11, and the outer wall of the rotating block 9 is provided with an anti-slip strip. Specifically, the insulating plate 5 separates each coil 6 to prevent the coils 6 from contacting each other, while the inner plate 11 prevents the coils 6 and the first support shaft 15 from getting tangled with the second support shaft 16.

[0020] Working principle: Rotating the rotating block 9 controls the rotation of the threaded rod 17, which in turn controls the upper slider 12 to move on the outer wall of the sliding shell 13, thereby controlling the rotation of the first support shaft 15. This, in turn, drives the second support shaft 16 to rotate, controlling the lower slider 12 to move, thus controlling the movement of the sliding shaft 14. This allows adjustment of the distance between the top block 4 and the bottom plate 1. The required number of coils 6 are then placed between the bottom plate 1 and the top block 4. An insulating plate 5 is placed between adjacent coils 6 for isolation. Multiple connecting wires 7 are then connected to the top side of the connecting circuit board 3 and fixed in place by the connector 8. The adjustable distance between the top block 4 and the bottom plate 1 allows for better installation of coils 6 of different grades. Meanwhile, the connecting copper plates 10 on the front of the multiple coils 6 are connected by copper plates.

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.
