Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, specifically to a magnetic device assembly structure. Background Technology
[0002] Currently, commonly used inductor or transformer bases are made of epoxy board, PBT or PET glued for fixing. During production, tooling is also required for positioning. With the continuous development of computing power, servers and new energy fields, low voltage and high current are required to adopt multi-group series and parallel structures. Due to the multi-winding structure, the requirements for positioning stability and manufacturability between them have increased. Traditional methods require a large number of tooling fixtures for positioning and turnover, which is not only inefficient, but also requires additional glue for fixing. Human error can also cause the fixtures to be out of place, resulting in low production efficiency and defective scrap.
[0003] The base snap-fit assembly utilizes structural locking points for positioning and fixation to achieve product structural stability. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a magnetic device assembly structure that solves the problems mentioned in the background art, such as the need for a large number of tooling fixtures for positioning and turnover, which is not only inefficient but also requires additional adhesive for fixing. Furthermore, human error can cause the fixtures to be misaligned, leading to low production efficiency and defective scrap.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic device assembly structure, comprising a magnetic core and a base. The magnetic core has multiple windings A and B inside. The bottom of each winding A and winding B has a pin, and a locking point is fixedly connected to one side of each pin. The surface of the base has multiple positioning holes A arranged in a rectangular array. The multiple positioning holes A are evenly divided into two groups, and the two groups of positioning holes A are respectively opened at the edge of the surface of the base. A positioning hole B is opened between each of the two groups of positioning holes A. The inner walls of the positioning holes A and positioning holes B are provided with limiting components.
[0006] Optionally, the windings A and B are engaged with the base via a limiting component, and the multiple windings A and B correspond to the positioning holes A and B opened on the base, respectively. The multiple windings A and B are evenly and equidistantly arranged in the magnetic core.
[0007] Optionally, the pins at the bottom of winding A and winding B are engaged with the limiting component via a snap-fit point, and the lower surface of the snap-fit point is rounded.
[0008] Optionally, the limiting component includes sliding grooves respectively formed on the inner walls of positioning hole A and positioning hole B. The inner bottom wall of the sliding groove is fixedly connected to two symmetrically arranged return springs. The other end of the two return springs is fixedly connected to a connecting block. The end of the connecting block away from the return spring is fixedly connected to a limiting block.
[0009] Optionally, the top edge of the limiting block is rounded, the connecting block is slidably connected to the base via a groove, and the top chamfer of the limiting block corresponds to the bottom chamfer of the latching point.
[0010] This utility model provides a magnetic device assembly structure, which has the following advantages:
[0011] 1. The magnetic device assembly structure, through the setting of pins, snap-fit points, positioning holes A and B, and limiting components, allows the operator to simply align the bottom pins of windings A and B with the positioning holes A and B on the base when it is necessary to fix them to the base. During insertion, the snap-fit points on the pins engage with the limiting components, thus fixing the pins to the base. This makes the device convenient, quick, time-saving, labor-saving, and highly reliable, while also reducing the cost of the device. Consequently, it is easy to promote and apply, and has great practicality and applicability. Attached Figure Description

[0020] The structures, proportions, sizes, etc. illustrated in this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed herein, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and objectives that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.
[0021] Please see Figures 1 to 6 This utility model provides a technical solution: a magnetic device assembly structure, including a magnetic core 1 and a base 2. The magnetic core 1 has multiple windings A3 and B4 inside. Each winding A3 and B4 has a pin 5 at its bottom. A locking point 6 is fixedly connected to one side of each pin 5. By directly positioning the locking point 6 at the pin 5, the windings A3 and B4 can be automatically engaged with the limiting component 9 on the base 2, eliminating the need for tooling positioning and adhesive fixing. This simplifies and speeds up the operation, effectively saving labor and adhesive curing time, achieving a time-saving, labor-saving, and convenient effect, thus significantly shortening the production cycle. The surface of the base 2 has multiple positioning holes A7 arranged in a rectangular array. A7 is divided into two groups, with each group of positioning holes A7 located at the edge of the base 2 surface. Positioning holes B8 are provided between the two groups of positioning holes A7. Limiting components 9 are provided on the inner walls of both positioning holes A7 and B8. When it is necessary to fix the bottom pins 5 of windings A3 and B4 onto the base 2, the operator simply aligns the bottom pins 5 of windings A3 and B4 with the positioning holes A7 and B8 on the base 2 and inserts them. During insertion, the locking points 6 fixed on the pins 5 engage with the limiting components 9, thus fixing the pins 5 to the base 2. This makes the device convenient, quick, time-saving, and labor-saving, with high reliability. It also reduces the cost of the device, making it easier to promote and apply, and possessing significant practicality and applicability.
[0022] Winding A3 and winding B4 are engaged with base 2 by limiting component 9. Multiple windings A3 and winding B4 correspond to positioning holes A7 and positioning holes B8 opened on base 2, respectively. Multiple windings A3 and winding B4 are evenly staggered and equidistantly arranged in magnetic core 1.
[0023] The pins 5 at the bottom of windings A3 and B4 are engaged with the limiting component 9 through the snap-fit point 6. The lower surface of the snap-fit point 6 has rounded corners. The rounded corner design of the snap-fit point 6 makes it easier to engage with the limiting component 9, achieving the effect of saving time and effort, and being convenient and quick.
[0024] The limiting component 9 includes a slide groove 91 respectively opened on the inner wall of the positioning hole A7 and the positioning hole B8. Two symmetrically arranged return springs 92 are fixedly connected to the inner bottom wall of the slide groove 91. A connecting block 93 is fixedly connected to the other end of the two return springs 92. A limiting block 94 is fixedly connected to the end of the connecting block 93 away from the return spring 92.
[0025] The top edge of the limiting block 94 is rounded. The connecting block 93 is slidably connected to the base 2 via the slide groove 91. The chamfer at the top of the limiting block 94 corresponds to the chamfer at the bottom of the snap-fit point 6. The rounded corners of both the limiting block 94 and the snap-fit point 6 facilitate the sliding of the limiting block 94 into the slide groove 91 when the snap-fit point 6 is inserted downward along the positioning hole A7 or positioning hole B8. This allows the limiting block 94 to slide into the slide groove 91 when it comes into contact with the snap-fit point 6. The connecting block 93 then compresses the return spring 92 in the slide groove 91. When the snap-fit point 6 is inserted to a certain distance, it separates from the limiting block 94, allowing the limiting block 94 to reset under the elastic potential energy of the return spring 92 and engage with the snap-fit point 6. This enables the windings A3 and B4 to engage on the base 2, thus achieving rapid assembly, effectively improving production efficiency, reducing production cycle, and providing a stable and neat structure.

For example, "connection" can be a fixed connection or an indirect connection through an intermediate component without affecting the relationship between components and the technical effect. It can also be an integral connection or a partial connection. In such cases, those skilled in the art can understand the specific meaning of the above terms in this utility model or utility model according to the specific circumstances.
