Description

Technical Field

[0001] This utility model relates to the field of magnetic components technology, and more specifically, to a magnetic core for use in electronic devices. Background Technology

[0002] In the field of electronic device technology, magnetic cores are used as key components in electronic components such as transformers, inductors, and filters, playing an important role in enhancing magnetic fields, guiding magnetic flux, and improving energy conversion efficiency.

[0003] For example, the magnetic core structure disclosed in patent announcement number CN220569490 U includes a number of magnetic core units evenly spaced along a first direction and a second direction. The magnetic core units are square. The first direction is parallel to the length direction of the magnetic core unit, and the second direction is parallel to the width direction of the magnetic core unit. A dielectric sheet is fixed between two adjacent magnetic core units in the first direction along the second direction, and a dielectric sheet is fixed between two adjacent magnetic core units in the second direction along the first direction to form an air gap. The magnetic core structure also includes a heat-conducting component.

[0004] In the above, the magnetic core units are bonded together with solid glue. Since the connection strength formed after the glue cures is high, once the magnetic core fails and needs to be repaired or replaced, the disassembly process is often cumbersome and time-consuming, and may even damage surrounding electronic components, increasing maintenance costs and difficulty. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic core for electronic devices that is easy to disassemble and reduces maintenance costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A magnetic core for use in electronic devices includes several individual magnetic core units, with adjacent magnetic core units being detachably connected. The magnetic core unit is equipped with side plates and mounting posts, which are fixed to both sides of the magnetic core unit respectively. A connecting groove is provided on the side plate, and the mounting post extends into the connecting groove and magnetically connects with the inner wall of the connecting groove. A groove is provided on the inner wall of the connecting groove. The outer wall of the mounting column has protrusions that are elastic and are positioned within and connected to grooves. A connecting rod is provided between the side plate and the mounting column. The connecting rod passes through the side plate and is placed in the connecting groove, and is inserted into the mounting column.

[0007] The present invention is further configured such that: a through hole is provided on one side of the side plate for the connecting rod to pass through, the through hole is connected to the connecting groove, a blind hole is provided on the mounting column, and one end of the connecting rod is connected to the blind hole.

[0008] The present invention is further configured such that: a first magnetic block is provided on the inner wall of the connecting groove, and a second magnetic block connected to the first magnetic block is provided on the outer wall of the mounting column.

[0009] The present invention is further configured such that: there are two grooves and two protrusions, and the two protrusions are respectively fixed on both sides of the mounting post.

[0010] By adopting the above technical solution, the beneficial effects of this utility model are as follows: The design of the magnetic assemblies and locking mechanisms allows for easy disassembly of individual magnetic core units. When it is necessary to replace or repair a magnetic core unit, simply release the locking mechanism and separate the magnetic assemblies without damaging surrounding electronic components. This makes maintenance of the magnetic core units more convenient, thereby facilitating disassembly and reducing maintenance costs. The connecting rods then secure the magnetic core units together, further improving their stability. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., 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, and 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. Therefore, they should not be construed as limitations on this utility model.

[0015] like Figures 1 to 2As shown, the magnetic core used in electronic devices includes several magnetic core units 1. The mounting posts 3 on the magnetic core units 1 are placed at the connecting grooves 4 of the side plates 2 on the adjacent magnetic core units 1. The mounting post 3 extends into the connecting groove 4, causing the second magnetic block 11 on the mounting post 3 and the first magnetic block 10 on the inner wall of the connecting groove 4 to magnetically adhere, thus achieving one-time fixation between adjacent magnetic core units 1. The second magnetic block 11 is bonded and fixed to the mounting post 3, and the first magnetic block 10 is also bonded and fixed to the inner wall of the connecting groove 4. When the first magnetic block 10 and the second magnetic block 11 are fixed, the protrusion 6 is elastic, so that the protrusion 6 is engaged and fixed in the groove 5, realizing secondary fixation between adjacent magnetic core units 1. One end of the protrusion is integrally formed with the mounting post 3. There are two grooves 5 and two protrusions 6. The two grooves 5 are on both sides of the inner wall of the connecting groove 4, and the two protrusions 6 are on both sides of the mounting post 3. The two protrusions are engaged and fixed with the corresponding grooves 5. There are two connecting rods 7, two through holes 8 and two blind holes 9. The two connecting rods 7 are on both sides of the side plate 2, the two through holes 8 are also on both sides of the side plate 2, and the two blind holes 9 are on both sides of the mounting post 3.

[0016] Two connecting rods 7 pass through the corresponding through holes 8 on the side plate 2 respectively. At this time, one end of the connecting rod 7 is in the connecting groove 4. Then, force is applied to the connecting rod 7 to push it towards the mounting post 3. The connecting rod 7 and the blind hole 9 on the mounting post 3 engage and fix it. Through the connecting rod 7, the side plate 2 and the mounting post 3 are fixed, realizing the three-fold fixation between adjacent magnetic core units 1.

[0017] Working principle: Pull the connecting rod 7 outward with force. The connecting rod 7 is pulled out of the blind hole 9 and then pulled out of the connecting groove 4 and the through hole 8 in sequence. Then, pry one of the magnetic core units 1 outward so that the mounting post 3 on the magnetic core unit 1 is pulled out of the connecting groove 4 on the adjacent magnetic core unit 1. When pulled out, the first magnetic block 10 and the second magnetic block 11 separate. At the same time, the protrusion 6 is pulled out of the groove 5. In this way, the magnetic core unit 1 can be disassembled from the magnetic core unit 1.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
