Description

Technical Field

[0001] The present invention relates to the technical field of magnetic core structures, and particularly to a assembled magnetic core structure for electronic components. Background Art

[0002] A magnetic core is a magnetic metal oxide sintered from various iron oxide mixtures and is widely used in coils and transformers of electronic devices. Common magnetic core materials include manganese-zinc ferrite and nickel-zinc ferrite. Among them, manganese-zinc ferrite has the characteristics of high magnetic permeability, high magnetic flux density, and low loss; while nickel-zinc ferrite has an extremely high impedance rate and low magnetic permeability, which makes the ferrite magnetic core play an important role in electronic devices.

[0003] At present, the common shapes of magnetic cores are toroidal and E-shaped. The toroidal magnetic core forms a magnetic field by inserting a coil into its central cavity area; the E-shaped magnetic core is formed by installing two identical magnetic cores facing each other to form a square figure-eight structure, thereby generating a magnetic field in the middle area of the transformer skeleton. The shapes of the two magnetic cores are different, and the applicable usage environments are also different. However, in the actual application process, the existing magnetic core structures often adopt integral molding of magnetic powder, and the shape is fixed and cannot be adjusted according to the equipment requirements. This means that when facing different devices or the same devices with different specifications, it is necessary to order magnetic cores of specific sizes or shapes, which not only increases the cost but also reduces the production flexibility and efficiency.

[0004] In view of this, in response to the above problems, it is necessary to propose a assembled magnetic core structure for electronic components that can flexibly adjust the shape and size according to actual needs to improve production efficiency and reduce costs. Summary of the Invention

[0033] In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The technical solutions of the present invention will be clearly and completely described below with reference to the drawings. It should be noted that the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Embodiment 1: A assembled magnetic core structure for electronic components, as Figures 1-8 shown, including:

[0035] The magnetic core body 1, which is a magnet in an isosceles triangle structure, is arranged with its plane facing upward. An inverted T-shaped groove 12 is opened at the top of the magnetic core body 1, and chamfers 11 are opened at the top corners on both sides of the magnetic core body 1. The chamfers 11 show a downward inclination trend, so that when two or more magnetic core bodies 1 are spliced, there is a larger activity space between adjacent magnetic core bodies 1, thus adapting to a larger range of position changes, so as to improve the flexibility and stability of the splicing between multiple magnetic core bodies 1;

[0036] The I-shaped blocks 2 are arranged in a staggered height on the two side waists of the magnetic core body 1. When adjacent magnetic core bodies 1 are connected, the I-shaped blocks 2 arranged on the opposite faces of the two are also arranged in a staggered manner. As a result, the I-shaped blocks 2, as the carrier for connecting and assembling multiple magnetic core bodies 1, are arranged in a staggered height manner, which can avoid the stress concentration problem caused by the connection points being on the same horizontal plane, effectively disperse the acting force applied to the magnetic core body 1, and thus increase the stability and load-bearing capacity of the overall structure during splicing, which plays an important role in constructing an efficient and compact magnetic core structure for electronic components;

[0037] The first connecting plate 3 is buckled on the I-shaped block 2 on one side of the magnetic core body 1. Both the front and rear sides of the top of the first connecting plate 3 have hinged ends 31, and the hinged ends 31 extend upward. An installation shaft 311 is rotatably arranged between the two hinged ends 31. A second connecting plate 32 is arranged on the installation shaft 311. Right-angled cutouts 321 are opened on both the front and rear sides of the top of the second connecting plate 32. The second connecting plate 32 is connected to the I-shaped block 2 of the adjacent magnetic core body 1 on the other side in a buckling manner;

[0038] Both the connecting plate one 3 and the connecting plate two 32 are provided with fitting grooves 30, and the fitting grooves 30 on both sides respectively correspond to and are adapted to the I-shaped blocks 2 with different height differences;

[0039] Specifically, as shown in Figure 4 When splicing operations are required, in order to ensure the stable assembly between two or more magnetic core bodies 1, the articulated connecting plate one 3 and connecting plate two 32 are specially designed as connecting media. Since the opposite surfaces between the magnetic core bodies 1 have I-shaped blocks 2 with different heights as installation carriers, the connecting plate one 3 and the connecting plate two 32 respectively correspond to and are adapted to the I-shaped blocks 2 on one side, and the fitting grooves 30 between them are also designed adaptively according to the height positions of the I-shaped blocks 2, so as to better buckle the I-shaped blocks 2 at the corresponding positions, making the connection between the magnetic core bodies 1 tight and ensuring a more firm buckling effect. Moreover, the materials of the above components are made of the same material as the magnetic core body 1, which helps to maintain the consistency and stability of the magnetic field within the entire structure and reduce the magnetic field interference problems caused by material differences;

[0040] More importantly, the connecting plate one 3 and the connecting plate two 32 are both in conformity with the contact surfaces of the corresponding magnetic core bodies 1 in contact, improving the installation convenience and also ensuring high stability during use, preventing performance degradation caused by loosening;

[0041] There is one column core one 7, and the top of the column core one 7 is connected to the column core two 72. Connectors are provided at the ends of the column core two 72 and the column core one 7 that are away from each other. When the magnetic core bodies 1 are in an E-shaped splicing trajectory 101, the connectors at both ends are respectively buckled between the adjacent two T-shaped grooves 12 to form the middle strut of the supporting E-shaped magnet structure, effectively increasing the stability of the magnetic core bodies 1 spliced into an E-shaped structure, ensuring the stable support in the middle of the structure, forming an "8" shape formed by the installation of two existing E-shaped magnetic cores, meeting the actual use requirements, and enhancing the anti-deformation ability of the overall structure.

[0042] The connector includes a support plate 6 provided at the ends of the column core one 7 and the column core two 72 that are away from each other, and connection ends 61 that are symmetrically provided on the support plate 6 and are in snap-fit with the T-shaped grooves 12.

[0043] A convex ring 71 is provided at the top of the column core one 7, and an inner ring 711 is provided inside the convex ring 71. The top surface of the inner ring 711 is lower than the highest point of the convex ring 71. A fitting groove 721 is opened at the end of the column core two 72, and the fitting groove 721 is in snap-fit with the connected convex ring 71 and inner ring 711.

[0044] During use, when multiple magnetic core bodies 1 need to be spliced into an annular structure, as shown in Figure 2, first determine the overall annular splicing trajectory 100, arrange and place each magnetic core body 1 in the installation area, and then place the connection structure composed of the connecting plate 1 3 and the connecting plate 2 32 between two adjacent magnetic core bodies 1, and ensure that the fitting grooves 30 on the connecting plate 1 3 and the connecting plate 2 32 are tightly fitted on the I-shaped block 2 at the corresponding position by sliding and buckling, so that a connection is formed between two unrelated magnetic core bodies 1, and this step is repeated until a connection structure is provided between all adjacent magnetic core bodies 1, thereby realizing an integrated connection. At the same time, according to the requirements of the magnetic core specifications, rotation adjustment is allowed, so that the connecting plate 2 32 can rotate along the corresponding installation axis 311 to adapt to different splicing positions, ensure the flexibility of the splicing process, and finally form a closed annular magnetic core structure;

[0045] When the magnetic core body 1 needs to be spliced ​​into an E-shaped structure, see Figure 3 First, determine the overall E-shaped splicing track 101, then arrange the core bodies 1 according to the track, and connect them using the connecting plate 1 3 and the connecting plate 2 32 in the same way as the above-mentioned annular splicing operation. Since the E-shaped structure covers the right-angle corner area, the angle position between the adjacent core bodies 1 can be adjusted by rotating the connecting plate 2 32 during this process. The design of the bevel 11 and the cutout 321 allows a greater degree of angle adjustment, thereby ensuring flexibility during structural splicing. After completing the frame structure of the core body 1, the column core 1 7 and the column core 2 72 can be connected so that the fitting groove 721 fits tightly against the convex ring 71 and the inner ring 711, thereby achieving the clamping of the column core 1 7 and the column core 2 72. Finally, the connecting end 61 on the support plate 6 is slidably inserted into the T-shaped groove 12 in the middle area to ensure the stable connection of the upper and lower core bodies 1, forming a pillar in the middle of the frame structure, completing the "8"-shaped structure of the E-shaped structure, and thus completing the splicing.

[0046] It can be seen that this solution uses innovative splicing technology to achieve the connection between the magnetic cores, achieving adaptation to various forms of conversion and use, greatly improving the flexibility and stability of the magnetic core connection, making the connection between the magnetic cores tighter, and being able to cope with complex usage environments and meet changing application requirements, thereby significantly improving the reliability and adaptability of the structure.

[0047] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a convex rod 4 is provided on one side of the connecting plate 2 32, a positioning rod 41 is rotatably provided on the convex rod 4, a card slot 411 is arranged on the positioning rod 41, and a card block 42 that is adapted to the card slot 411 is slidably embedded on the connecting plate 1 3, and the card block 42 and the positioning rod 41 are both made of magnetic material, so that the card block 42 can be snapped into the card slot 411 through magnetic attraction.

[0048] Specifically, through the cooperative design of the positioning rod 41 with multiple card slots 411 and the clamping block 42, a flexible and stable connection method is achieved. The positioning rod 41 can rotate and can be fixed by selecting different card slots 411 according to actual needs. The clamping block 42 is embedded into the selected card slot 411 through magnetic adsorption, thereby locking the position of the positioning rod 41. This design forms a stable triangular fixing structure among the connecting plate one 3, the connecting plate two 32, and the positioning rod 41, ensuring the stability after multi-angle position adjustment.

[0049] In this way, the splicing between the magnetic core bodies 1 is no longer limited to a single angle or position, and can adapt to more complex installation requirements. It not only enhances the connection stability and adjustment flexibility of the overall structure, but also simplifies the assembly process, enabling precise alignment and fastening without complex tools or steps, thereby improving work efficiency.

[0050] As Figure 1 、 Figure 2 、 Figure 3 and Figure 7 shown, a fastening frame 5 is provided on the connecting plate one 3, and an extension block 51 that matches the fastening frame 5 is provided on the connecting plate two 32. When the magnetic core bodies 1 form an annular splicing trajectory 100, the extension block 51 is fastened and connected to the adjacent fastening frame 5.

[0051] Specifically, the connection and cooperation between the extension block 51 and the fastening frame 5 can achieve the stable connection between adjacent magnetic core bodies 1 and enhance the stability of the overall structure. When the magnetic core bodies 1 are arranged according to the annular splicing trajectory 100, it not only strengthens the overall peripheral interval, but also effectively prevents loosening problems caused by external vibration or external force, ensuring seamless docking between each component and improving the overall assembly quality.

[0052] At the same time, it is particularly suitable for application scenarios that require the formation of a closed ring structure, such as the annular splicing trajectory 100. The tight cooperation between the fastening frame 5 and the extension block 51 improves the compactness after overall splicing, making the entire structure look more compact and fitting.

[0053] As Figure 2 、 Figure 3 and Figure 4As shown, it further includes a closing plate 13. The number of the closing plates 13 is the same as that of the magnetic core body 1. A T-shaped end 131 that is snap-fitted with the T-shaped groove 12 is provided on each closing plate 13 for closing the top end of the magnetic core body 1. By providing the T-shaped end 131 that matches the T-shaped groove 12 on the closing plate 13, an effective closing of the T-shaped groove 12 at the top end of the magnetic core body 1 can be achieved, enhancing the sealing performance and protection ability of the overall structure. At the same time, the snap-fitting design between the T-shaped end 131 and the T-shaped groove 12 enables the closing plate 13 to be quickly and accurately installed on the magnetic core body 1 without complex tools or additional steps, greatly simplifying the installation process and improving work efficiency.

[0054] 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 the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
