[0028] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the description order of the following embodiments is not intended to limit the priority order of the embodiments.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 The magnetic device of the present application includes a skeleton 1, a magnetic core 5 and a boss connector 8. Specifically, the skeleton 1 includes a winding portion 2, an inner column connecting portion 3 and a platform mounting portion 4. The winding portion 2 is used to accommodate a winding coil (not shown), the platform mounting portion 4 is connected to both ends of the winding portion 2, and the inner column connecting portion 3 is opened on the winding portion 2.

[0030] That is, the skeleton 1 is the structural basis of the magnetic device, which can support and fix the winding coil and the magnetic core 5, wherein the magnetic core 5 is provided with a middle column connector 6, and the middle column connector 6 extends into the inner column connecting part 3, so that the magnetic core 5 is connected to the skeleton 1, ensuring the firm connection between the magnetic core 5 and the skeleton 1. Furthermore, the shape and size of the middle column connector 6 can match the design of the inner column connecting part 3 to ensure good mechanical clearance and electrical performance.

[0031] The platform mounting portion 4 of the present application is connected to both ends of the winding portion 2, and can be used as the main supporting structure of the skeleton 1, as well as for connecting other components, wherein the middle column connector 6 has a functional end face 7 on the side facing the platform mounting portion 4, and the functional end face 7 has a preset gap J with the platform mounting portion 4, and the boss connector 8 is arranged at the end of the platform mounting portion 4 facing the functional end face 7. Specifically, the end of the boss connector 8 facing away from the platform mounting portion 4 abuts against the functional end face 7 of the middle column connector 6, thereby, the boss connector 8 respectively connects the platform mounting portion 4 and the functional end face 7 of the magnetic core 5 in the preset gap J, thereby increasing the stability of the magnetic core 5, that is, the boss connector 8 can provide a stable support point during the connection process between the magnetic core 5 and the skeleton 1, and during the subsequent operation of the magnetic device, to help better disperse the mechanical stress borne by the magnetic core 5, avoid the undesirable phenomenon of the middle column of the magnetic core breaking, and improve the reliability and safety of the magnetic device.

[0032] In one embodiment, the inner column connecting portion 3 is concentric with the winding portion 2, that is, the central axes of the inner column connecting portion 3 and the winding portion 2 coincide. Thus, it is convenient for the magnetic core 5 to be assembled on the skeleton 1 through the middle column connecting body 6, and the magnetic flux path is optimized. That is, the middle column connecting body 6 of the magnetic core 5 can be parallel to the central axis of the winding portion 2, so that the magnetic flux can effectively flow inside the magnetic core 5, optimizing the magnetic flux density of the magnetic core 5, improving the overall performance of the magnetic device. At the same time, it can also ensure that the middle column connecting body 6 of the magnetic core 5 is uniformly stressed during assembly, reducing stress concentration caused by asymmetric stress and reducing the risk of fracture of the middle column of the magnetic core.

[0033] It should be noted that the inner wall of the inner column connecting portion 3 protrudes from the platform mounting portion 4, thus providing a clearance space for the connection of the middle column connecting body 6 of the magnetic core 5, facilitating the assembly of the magnetic core 5 on the skeleton 1 through the middle column connecting body 6. Among them, the inner wall of the inner column connecting portion 3 and the platform mounting portion 4 have a minimum set distance, and the height value of the boss connecting body 8 relative to the platform mounting portion 4 is not less than the minimum set distance, so as to ensure that when the boss connecting body 8 contacts the functional end face 7 of the magnetic core 5, sufficient supporting force can be provided, thereby dispersing the external stress that the magnetic core 5 may receive during use and avoiding fracture of the middle column of the magnetic core due to excessive local stress.

[0034] Among them, the middle column connecting body 6 and the upper surface of the inner wall of the inner column connecting portion 3 have a maximum installation gap K, so as to facilitate the quick assembly of the magnetic core 5 onto the skeleton 1 through the cooperation of the middle column connecting body 6 and the inner column connecting portion 3, avoiding structural jamming. Then, the height value of the boss connecting body 8 relative to the platform mounting portion 4 ≥ the preset gap J, and the height value of the boss connecting body 8 relative to the platform mounting portion 4 < the sum of the preset gap J and the maximum installation gap K, so as to avoid structural interference between the middle column connecting body 6 and the inner column connecting portion 3 caused by the support of the boss connecting body 8, and avoid uneven stress during the installation and operation of the magnetic core 5, improving the reliability of the device.

[0035] In an application scenario, based on the design that the preset gap J ≤ the height value of the boss connecting body 8 relative to the platform mounting portion 4 < the sum of the preset gap J and the maximum installation gap K, the central axes of the middle column connecting body 6 of the magnetic core 5, the inner column connecting portion 3, and the winding portion 2 coincide, thus optimizing the magnetic flux path and the magnetic flux density of the magnetic core 5, and improving the overall performance of the magnetic device.

[0036] In one embodiment, both the functional end face 7 and the end of the boss connecting body 8 facing away from the platform mounting portion 4 are parallel to the horizontal plane. This design helps to optimize the mechanical performance and assembly accuracy of the magnetic device, enabling the magnetic core 5 to be uniformly stressed when contacting the boss connecting body 8, avoiding local stress concentration caused by uneven contact surfaces, and also making the contact between the boss connecting body 8 and the functional end face 7 more stable and tight, thereby enhancing the stability and aesthetics of the entire structure.

[0037] Among them, both ends of the winding part 2 are symmetrically provided with wire blocking parts 9. The wire blocking parts 9 are integrally connected to the platform mounting part 4. By limiting and guiding the winding coil through the wire blocking parts 9, the stability of the coil and the precision of winding are improved. Moreover, since the wire blocking parts 9 are integrally connected to the platform mounting part 4, the overall structural strength of the bobbin 1 is ensured.

[0038] In one embodiment, there is at least one boss connector 8, and the boss connector 8 is integrally connected to the platform mounting part 4. The design of integral connection can ensure that the relative positions and heights between each boss connector 8 and the platform mounting part 4 are consistent, reducing the joint interfaces between components, thereby improving the overall strength and stability of the structure.

[0039] On the other hand, there are multiple boss connectors 8, and the multiple boss connectors 8 are linearly arranged at one end of the platform mounting part 4 facing the functional end face 7. The multiple linearly arranged boss connectors 8 can evenly distribute the forces on the magnetic core 5 during installation and operation, avoiding concentrated stress points, thereby reducing local stress concentration, and also avoiding the movement or instability of the magnetic core caused by insufficient single support points, ensuring the reliable operation of the magnetic device.

[0040] Of course, the number of boss connectors 8 can be increased or decreased according to actual environmental needs in this application to ensure the structural flexibility of the magnetic device.

[0041] In one embodiment, a terminal assembly groove 10 is provided on the platform mounting part 4, and the boss connectors 8 can be located on both sides of the terminal assembly groove 10. The terminal assembly groove 10 is used to install electrical terminals or connectors. The boss connectors 8 are located on both sides of the terminal assembly groove 10 to avoid structural interference with the electrical connection of the electrical terminals, and can also make the entire magnetic device look neater and more consistent visually.

[0042] It should be noted that there is an arrangement spacing between adjacent boss connectors 8, and the arrangement spacing is adjustable. In the design of magnetic devices, different magnetic cores and terminals may have different sizes or installation requirements. Then, the adjustable arrangement spacing can be adjusted according to specific application scenarios to ensure that the boss connectors 8 play their roles. Moreover, by adjusting the arrangement spacing, the layout of the boss connectors 8 can be optimized according to the actual load and force conditions, improving the reliability of the magnetic device.

[0043] The above has introduced this application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the core idea of this application; at the same time, for those skilled in the art, based on the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
