[0027] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] Currently, transformers are provided with various structures according to the core form. To meet the high-frequency requirements of transformers, EQ-type transformers are mostly used. However, in this structure, the windings are wrapped by the columns on both sides of the magnet, and it is very inconvenient to wind the coils of the windings in this structure.

[0029] Based on the above technical problems, please refer to Figure 1 and Figure 2 , the present application provides a transformer 1000, and the transformer 1000 includes a core assembly 100, a first winding assembly 200, and a second winding assembly 300.

[0030] In some embodiments, please refer to Figure 2 , the core assembly 100 includes a core body 110, a first magnetic arm 120, and a second magnetic arm 130. The first magnetic arm 120 and the second magnetic arm 130 are fixed to the core body 110, and the first magnetic arm 120 and the second magnetic arm 130 are disposed opposite to each other.

[0031] In some embodiments, please refer to Figure 2The first winding assembly 200 includes a first winding 210 and a second winding 220 . The first winding 210 is wound around the first magnetic arm 120 , and the second winding 220 is wound around the second magnetic arm 130 .

[0032] In some embodiments, see Figure 2 The second winding assembly 300 includes a first metal sheet 310 and a second metal sheet 320. The first metal sheet 310 is buckled on the first winding 210 and electrically connected to the first magnetic arm 120. The second metal sheet 320 is buckled on the second winding 220 and electrically connected to the second magnetic arm 130.

[0033] In combination with the above embodiment, the first winding 210 is wound around the first magnetic arm 120, and the second winding 220 is wound around the second magnetic arm 130. Finally, the first metal sheet 310 is buckled on the first winding 210, and the second metal sheet 320 is buckled on the second winding 220 to facilitate installation.

[0034] It should be noted that the magnetic core body 110, the first magnetic arm 120 and the second magnetic arm 130 together constitute the magnetic core body 110, so that a gap is left between the first metal sheet 310 and the first winding 210, and a gap is left between the second metal sheet 320 and the second winding 220, thereby increasing the exposed area of ​​the first winding 210 and the second winding 220, thereby increasing the heat exchange efficiency and improving the working efficiency of the transformer 1000. The material of the first metal sheet 310 includes copper, aluminum, etc. The material of the second metal sheet 320 includes copper, aluminum, etc. The first metal sheet 310 and the second metal sheet 320 are both bent in a "冂" shape to facilitate buckling on the first winding 210 or the second winding 220.

[0035] In some embodiments, a gap is left between the first metal sheet 310 and the first winding 210, and a gap is left between the second metal sheet 320 and the second winding 220. Optionally, only the side surfaces of the first winding 210 and the second winding 220 facing each other are blocked and covered, thereby increasing the exposed area of ​​the first winding 210 and the second winding 220 and further improving the heat exchange efficiency.

[0036] In order to optimize the installation of the transformer 1000 and improve the efficiency of mass production, the coil of the first winding 210 is directly wound on the first magnetic arm 120, and the coil of the second winding 220 is directly wound on the second magnetic arm 130. This structure can also be improved as follows.

[0037] For the first winding assembly 200, see Figure 2 The first winding assembly 200 further includes a first sleeve 230 and a second sleeve 240 .

[0038] In some embodiments, a first bushing 230 is provided on the first magnetic arm 120, and a first winding 210 is wound around the first bushing 230. A second bushing 240 is sleeved on the second magnetic arm 130, and a second winding 220 is wound around the second bushing 240.

[0039] It should be noted that the contour of the first bushing 230 is similar to the outer contour of the first magnetic arm 120, and both can be a prism, a cylinder, etc.; the contour of the second bushing 240 is similar to the outer contour of the second magnetic arm 130, and both can be a prism, a cylinder, etc. That is, in this embodiment, the first winding 210 is wound around the first bushing 230 in advance to facilitate installation on the first magnetic arm 120, and the second winding 220 is wound around the second bushing 240 to facilitate installation on the second magnetic arm 130. It should still be noted that the end portions at both ends of the first bushing 230 protrude relative to the middle portion, so as to prevent the first winding 210 from axially slipping out of the first bushing 230 along the first bushing 230; the end portions at both ends of the second bushing 240 protrude relative to the middle portion, so as to prevent the second winding 220 from axially slipping out of the second bushing 240 along the second bushing 240.

[0040] In some embodiments, please refer to Figure 3 , the transformer 1000 further includes a mounting base 400, and the mounting base 400 is provided with a first mounting groove 410 and a second mounting groove 420.

It should still be noted that the mounting base 400 is generally in a platform shape, and the first mounting groove 410 and the second mounting groove 420 are recessed. In order to make the first bushing 230 stably installed, the number of the first mounting portions 231 is two, which are respectively arranged at both ends of the first bushing 230. Correspondingly, the number of the first mounting grooves 410 is also two. It can be understood that the coil of the first winding 210 has an input end and an output end, so the structures of the first mounting portions 231 on both sides can be different to adapt to the input end and the output end. Correspondingly, the size of the first mounting groove 410 also needs to be increased or decreased to adapt to the structure of the first mounting portion 231. In order to make the second bushing 240 stably installed, the number of the second mounting portions 241 is two, which are respectively arranged at both ends of the second bushing 240. Correspondingly, the number of the second mounting grooves 420 is also two. It can be understood that the coil of the second winding 220 has an input end and an output end, so the structures of the second mounting portions 241 on both sides can be different to adapt to the input end and the output end. Correspondingly, the size of the second mounting groove 420 also needs to be increased or decreased to adapt to the structure of the second mounting portion 241.

Accordingly, the number of second through holes 440 is multiple, such as two, three, etc.

[0048] Specifically, see Figure 5 The first extension part 311 as the positive and negative poles of the secondary coil is arranged on the side of the mounting base 400 away from the second winding 220, and one first through hole 430 is arranged here, and both first extension parts 311 pass through the first through hole 430 to pass through the mounting base 400.

[0049] During the use and transportation of the transformer 1000, in order to facilitate the electrical connection between the first winding assembly 200 as the primary side and other components, pins need to be reserved.
