[0002] With the rapid development of electronic technology, toroidal common-mode inductors are increasingly used in various electronic devices. However, existing toroidal common-mode inductor base designs have many shortcomings, limiting their performance and efficiency in practical applications.

[0003] First, the traditional toroidal common-mode inductor base design often requires the length and width of the base to increase accordingly as the thickness of the magnetic core increases. This not only leads to an increase in material usage and rising costs, but also increases the weight of the base, which is not conducive to the lightweight design of the product. Secondly, during the dispensing process of the base, due to design defects, glue leakage and glue dripping are very likely to occur, which not only affects the appearance of the product, but also may pose a potential threat to the performance and reliability of the product. In addition, the existing base and magnetic core are prone to misalignment during the assembly process, and it is impossible to directly locate the center position of the base for installation. This not only increases the difficulty of assembly, but may also affect the performance and stability of the product. Utility Model Content

In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0036] The following combination Figures 1-6 The present invention provides a toroidal common-mode inductor base, which is used to place a toroidal common-mode inductor.

[0037] In some embodiments, as Figures 1 to 6 As shown, the annular common-mode inductor base includes a base body 100 and an extension portion 200. The top of the base body 100 is formed with an arcuate groove 110 for accommodating the annular common-mode inductor, and the side of the base body 100 is provided with a guide groove 120. The extension portion 200 is connected to the edge of at least one side of the bottom of the base body 100. The extension portion 200 is formed with a slot 230 for the pins of the annular common-mode inductor to pass through. One end of the guide groove 120 extends to the arcuate groove 110, and the other side of the guide groove 120 extends to the extension portion 200.

[0038] In this embodiment, the base body 100 is made of a high-strength, high-thermal-conductivity material, such as aluminum alloy or stainless steel, to ensure structural stability and heat dissipation performance. The top of the base body 100 features an arc-shaped groove 110. The shape and dimensions of this groove are customized based on the shape of the annular common-mode inductor to ensure that the inductor can be stably and accurately positioned within the groove. This design not only improves inductor installation efficiency but also effectively prevents the inductor from shifting or tilting during installation.

[0039] One or more guide grooves 120 are provided on the side of the base body 100. One end of these guide grooves 120 is connected to the arc-shaped groove 110 at the top, and the other end extends to the extension portion 200 at the bottom of the base body 100. The design of the guide groove 120 provides clear guidance for the installation of the pins on the inductor. In addition, during the subsequent glue dispensing, the glue can be guided to the extension portion 200 through the guide groove 120 and will not drip directly onto the ground. The extension portion 200 is connected to at least one side edge of the bottom of the base body 100, and it plays the role of fixing and supporting the inductor pins. For example, the arc-shaped groove 110 on the base body 100 is raised on the left and right sides, and the front and back sides are hollowed out, then the extension portion 200 is arranged on the front and / or back sides, and at this time the extension portion 200 can effectively block the glue dripping from the glue dispensing.

[0040] The extension portion 200 is provided with a plurality of slots 230. The size and position of these slots 230 are determined by the number and layout of the pins on the annular common-mode inductor. The pins can easily pass through these slots 230 to connect to a circuit board or other electrical components.

[0041] The annular common-mode inductor base provided by the present invention has an arc-shaped groove 110 formed on the top of the base body 100, which can accurately place the annular common-mode inductor. There is no need for complicated positioning steps. Direct placement can ensure that the inductor is in the correct position, which greatly simplifies the assembly process and improves production efficiency. The guide groove 120 set on the side not only provides a clear guide for the setting of the pins, but also during the subsequent glue dispensing, the glue can be guided to the extension part 200 through the guide groove 120 instead of dripping directly onto the ground. The slots 230 formed on the extension part 200 are specially designed for the pins of the annular common-mode inductor to pass through, so that the pins can pass through neatly and orderly, avoiding crossing or confusion between the pins. It is both beautiful and convenient for subsequent electrical connection and packaging processing.

[0042] In some embodiments, as Figures 1 to 6As shown, the edge portion 200 is provided with at least two spaced-apart slots 230. The size and position of these slots 230 are determined based on the number and layout of the pins on the annular common-mode inductor. The at least two spaced-apart slots 230 ensure that the inductor pins are evenly distributed on the edge portion 200, thereby improving the reliability and stability of the connection between the pins and the circuit board or other electrical components.

[0043] In this embodiment, at least two guide grooves 120 are provided on the side of the base body 100. One end of each guide groove 120 extends to a different position on the arcuate groove 110, and the other end of each guide groove 120 faces a different position on a different extension portion 200. These guide grooves 120 are not randomly arranged, but rather each has one end precisely extending to a different position on the arcuate groove 110. At the same time, the other end of each guide groove 120 faces a different position on a different extension portion 200. This layout ensures that the pins can smoothly travel along the guide grooves 120 to the predetermined position during installation, and also ensures that the glue is evenly and effectively guided to the extension portion 200 during the dispensing process, avoiding contamination of the surrounding environment.

[0044] Specifically, the extension part 200 is provided with two, namely the first extension part 210 and the second extension part 220; the first extension part 210 is connected to the front side of the bottom of the base body 100, and the second extension part 220 is connected to the rear side of the bottom of the base body 100; a pair of slots 230 are provided on the first extension part 210, and a pair of slots 230 are provided on the second extension part 220; two guide grooves 120 are provided at intervals on the front side of the base body 100; two guide grooves 120 are provided at intervals on the rear side of the base body 100.

[0045] Specifically, the arc-shaped groove 110 on the base body 100 is raised on both sides, while the front and back sides are hollowed out. The first extension portion 210 is connected to the front side of the bottom of the base body 100, and the second extension portion 220 is correspondingly connected to the back side of the bottom of the base body 100. This arrangement allows the glue on the arc-shaped groove 110 to be guided to the extension portion 200 through the guide groove 120, rather than dripping directly onto the ground.

[0046] A pair of slots 230 are provided on the first extension 210. The position and size of these slots 230 are determined based on the specific layout and requirements of the front pins of the annular common-mode inductor. Similarly, a pair of slots 230 are provided on the second extension 220 to match the requirements of the rear pins of the inductor. This design ensures that the inductor pins can accurately pass through the corresponding slots 230.

[0047] In addition, two spaced-apart guide slots 120 are provided on the front and rear sides of the base body 100. The front guide slots 120 align with the slots 230 on the first extension 210, providing clear installation guidance for the front pins and guiding any glue dripping from the front. The rear guide slots 120 mate with the slots 230 on the second extension 220, ensuring smooth installation of the rear pins and guiding any glue dripping from the rear.

[0048] In summary, the annular common-mode inductor base greatly facilitates the installation of the annular common-mode inductor through the extension portion 200 and the guide slot 120. It not only ensures that the pins on the annular common-mode inductor are stably and accurately placed on the base, but also guides dripping glue to the extension portion 200.

[0049] In some embodiments, as Figure 1 As shown, the groove width of the guide groove 120 in the arc-shaped groove 110 is greater than the groove width of the guide groove 120 extending to the extended edge portion 200 .

[0050] The width of the guide groove 120 within the arc-shaped groove 110 is intentionally designed to be relatively large. This allows the glue to be better guided by the guide groove 120 when applying glue to the arc-shaped groove 110, facilitates the placement of the pins, and reduces the risk of installation difficulties or inductor damage caused by an overly narrow groove width.

[0051] However, when the guide groove 120 extends to the edge portion 200, its groove width is reduced so that the pin can be smoothly placed in the corresponding slot 230. By combining the different groove width designs of the guide groove 120 in the arc groove 110 and when extending to the edge portion 200, the annular common-mode inductor base provided by the utility model realizes the rapid and precise installation of the inductor, as well as the guidance of dripping glue during the gluing process.

[0052] like Figure 1 and Figure 2 As shown, two limiting protrusions 130 are formed on the top surface of the base body 100, and the two limiting protrusions 130 cooperate with the top surface of the base body 100 to form an arc-shaped groove 110. It is worth noting that this arc-shaped groove 110 adopts a fan-shaped design. The introduction of the fan-shaped groove not only further enhances the positioning and supporting ability of the base for the annular common-mode inductor, but also enables the inductor to fit more tightly in the groove during installation, reducing assembly errors caused by displacement or tilting. At the same time, the design of the fan-shaped groove also takes into account the stress conditions of the inductor in actual application. By optimizing the shape and size of the groove, the inductor can be more stably maintained in the predetermined position when subjected to external force, thereby improving the stability and reliability of the entire assembly.

[0053] In some embodiments, as Figure 2 and Figure 4 As shown, the base body 100 is hollowed out with an open bottom. This hollowed-out structure not only reduces the base's weight but also lowers material costs. The hollowed-out portion reduces unnecessary material usage without sacrificing overall strength, making the base lighter and stronger. This design not only improves the base's durability but also facilitates handling and installation during subsequent production and processing.

[0054] In some embodiments, as Figure 2 and Figure 4 As shown, the annular common-mode inductor base further includes a reinforcing rib 300 . The reinforcing rib 300 is disposed in the base body 100 and connected to the side wall inside the base body 100 .

[0055] Multiple reinforcing ribs 300 are provided inside the base body 100, and the multiple reinforcing ribs 300 are arranged in a cross or radial pattern. This allows the reinforcing ribs 300 to evenly distribute the forces borne by the base, improving the overall load-bearing capacity, enhancing the rigidity and stability of the base, and reducing the risk of deformation or damage caused by external forces.

[0056] At the same time, the introduction of the reinforcing ribs 300 does not increase the complexity and manufacturing cost of the base. On the contrary, through reasonable structural design and material selection, the reinforcing ribs 300 can be seamlessly connected to the base body 100, maintaining a neat appearance of the base while ensuring the stability of its internal structure.

[0057] In summary, the reinforcing ribs 300 not only improve the bearing capacity and stability of the base, but also optimize its internal structure, so that the base can more stably maintain its shape and size when subjected to external forces.

[0058] In some embodiments, as Figure 2 and Figure 4 As shown, the bottom surface of the edge extension portion 200 and / or the base body 100 is provided with an avoidance groove 400 for arranging solder.

[0059] The avoidance groove 400 is designed for practical electrical connection and soldering requirements. Soldering is a common method for mounting a toroidal common-mode inductor on a base and connecting it to a circuit board or other electrical components via pins. However, if the base does not have a avoidance groove 400, solder may overflow and accumulate on the base during soldering, affecting the base's flatness and stability and potentially interfering with or damaging surrounding electrical components.

[0060] Therefore, the introduction of the avoidance groove 400 is particularly important. By providing the avoidance groove 400 on the edge extension 200 and / or the bottom surface of the base body 100, a specific area for solder flow and accumulation is provided, preventing it from overflowing and affecting the base's performance. Furthermore, the design of the avoidance groove 400 can optimize the soldering process, ensuring a more even distribution of solder at the connection point between the pins and the circuit board, thereby improving soldering reliability and stability.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
