Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a stacked composite magnetic core structure. Background Technology

[0002] Magnetic cores are sintered magnetic metal oxides composed of various iron oxide mixtures and are crucial components in electronic devices. With technological advancements, magnetic core technology has continuously evolved, from traditional ferrite cores to high-performance composite cores, significantly improving core performance and stability. However, as electronic devices move towards miniaturization, lightweighting, and high performance, magnetic core technology faces new challenges: how to achieve higher integration and more flexible configuration while maintaining core performance.

[0003] In electronic devices, the stability and reliability of the magnetic core structure are crucial to the overall performance of the device. Traditional magnetic core structures often suffer from displacement after installation due to external influences, leading to structural instability and affecting performance. Current sensor core-frame hole assembly typically uses a clearance fit, where a small gap allows for slight core movement after assembly, impacting sensor stability. If the gap between the core and frame holes is zero, assembly becomes significantly more difficult. Utility Model Content

[0004] The main objective of this invention is to propose a stacked composite magnetic core structure that overcomes the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0006] A stacked composite magnetic core structure, comprising:

[0007] The frame is installed to support the components, and a core-penetrating hole is provided on one side near the middle.

[0008] The first magnetic core is roughly U-shaped, with part of it inserted into the core hole;

[0009] The second magnetic core is approximately L-shaped, with part of it inserted into the core hole;

[0010] The first and second magnetic cores are in contact with each other inside the core hole, and a protrusion is provided on the side of the first magnetic core that contacts the second magnetic core.

[0011] Furthermore, the first magnetic core includes a first part, a second part, and a third part. The first part and the third part are parallel. The two ends of the second part are connected to the first part and the third part, respectively. The third part is provided with a convex bulge and passes through the magnetic core hole to contact the second magnetic core. The first part passes through the mounting frame above the magnetic core hole.

[0012] Furthermore, the second magnetic core includes a fourth part, a fifth part, and a sixth part. The fourth part and the sixth part are parallel. The two ends of the fifth part are connected to the fourth part and the sixth part, respectively. The sixth part passes through the core hole and contacts the first magnetic core. The fourth part is inserted into the mounting frame above the core hole.

[0013] Furthermore, the first and second magnetic cores are arranged in a stacked manner within the core-passing hole.

[0014] Furthermore, the size of the hole through the magnetic core is just enough to accommodate both the first and second magnetic cores simultaneously, achieving an interference fit.

[0015] Furthermore, the mounting frame is made of a non-magnetic material.

[0016] Furthermore, the convex hull is in close contact with one side wall of the core hole.

[0017] Furthermore, the sides of the convex hull are semi-circular with a radius of 1 mm.

[0018] Furthermore, the contact point between the convex hull and the through-core hole forms an interference of 0.1 mm.

[0019] Furthermore, the materials of the first and second magnetic cores include, but are not limited to, a mixture of iron oxides.

[0020] This invention provides a stacked magnetic core structure that solves the problem of existing equipment being easily displaced by external influences after installation, resulting in structural instability. It has the advantages of being less prone to displacement and having stable products. The stable structure is achieved through the cooperation between the convex hull structure and the inner wall of the through-core hole, thus ensuring product stability. Attached Figure Description

[0029] The following is for reference. Figures 1 to 2 The present invention will be further described below:

[0030] A stacked composite magnetic core structure, comprising:

[0031] Mounting frame 1 is used to support the component, and a magnetic core hole 11 is provided on one side near the middle position;

[0032] The first magnetic core 2 is approximately U-shaped, with a portion inserted into the core hole 11.

[0033] The second magnetic core 3 is approximately L-shaped, with part of it inserted into the core hole 11.

[0034] The first magnetic core 2 and the second magnetic core 3 are in contact with each other inside the core hole 11. A protrusion 231 is provided on the side of the first magnetic core 2 that contacts the second magnetic core 3. The protrusion 231 is in close contact with one side wall of the core hole 11.

[0035] In this embodiment, the side of the convex hull 231 is semi-circular with a radius of 1 mm, and the contact point between the convex hull 231 and the through-core hole 11 forms an interference of 0.1 mm.

[0036] During the assembly process, the first magnetic core 2 is first assembled into the through-core hole 11 of the mounting frame 1, and then the second magnetic core 3 is assembled. When assembling the second magnetic core 3, the second magnetic core 3 presses against the first magnetic core 2. At this time, the protrusion 231 on the first magnetic core 2 presses against one side of the through-core hole 11, causing the inner side of the through-core hole 11 to undergo slight elastic deformation. This achieves the fixation of the magnetic core position and reduces the assembly difficulty.

[0037] The first magnetic core 2 includes a first part 21, a second part 22 and a third part 23. The first part 21 and the third part 23 are parallel. The two ends of the second part 22 are connected to the first part 21 and the third part 23 respectively. The third part 23 is provided with a protrusion 231 and passes through the core hole 11 to contact the second magnetic core 3. The first part 21 passes through the mounting frame 1 above the core hole 11.

[0038] The second magnetic core 3 includes a fourth part 31, a fifth part 32, and a sixth part 33. The fourth part 31 and the sixth part 33 are parallel. The two ends of the fifth part 32 are connected to the fourth part 31 and the sixth part 33 respectively. The sixth part 33 passes through the magnetic core hole 11 and contacts the first magnetic core 2. The fourth part 31 is inserted into the mounting frame 1 above the magnetic core hole 11.

[0039] The first magnetic core 2 and the second magnetic core 3 are arranged in a stacked manner in the core hole 11. The size of the core hole 11 is just enough to accommodate the first magnetic core 2 and the second magnetic core 3 at the same time, achieving an interference fit. Through the interference fit, the first magnetic core 2, the second magnetic core 3 and the mounting frame bracket 1 will not be displaced, thereby achieving a stable installation structure that is not easily affected by external vibrations and other factors, resulting in high product stability.

[0040] Preferably, the mounting frame 1 is made of a non-magnetic material, such as plastic or ceramic, to avoid affecting the magnetism of the magnetic core components.

[0041] In this embodiment, the mounting frame 1 is made of plastic, which can better achieve an interference fit with the first magnetic core 2.

[0042] The materials of the first magnetic core 2 and the second magnetic core 3 include, but are not limited to, iron oxide mixtures.

[0043] Optionally, an auxiliary fixing structure can be added to the device: a small protrusion or groove structure is added to the contact surface between the first magnetic core 2 and the second magnetic core 3 and the mounting frame 1, which further enhances the fixing effect of the magnetic core by physical locking and prevents displacement under extreme conditions.

[0044] Optionally, the materials of the first magnetic core 2 and the second magnetic core 3 may be high-performance magnetic core materials: magnetic core materials with high permeability and low loss, such as high-performance ferrite or rare earth magnets, may be selected to improve the magnetic properties and stability of the first magnetic core 2 and the second magnetic core 3.

[0045] Optionally, a wear-resistant coating may be applied to the contact surfaces of the first magnetic core 2 and the second magnetic core 3 with the mounting frame 1 to reduce friction and wear and extend service life.

[0046] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
