Description

Technical Field

[0001] This utility model relates to the field of magnetic core technology, and more specifically, to an anti-interference magnetic core. Background Technology

[0002] With the rapid development of electronic information technology, magnetic material components are increasingly widely used in computers, mobile phones, automation equipment, and electronic transformers. As a key component of these devices, the performance of the magnetic core directly affects the stability and reliability of the entire device. As electronic devices gradually develop towards higher frequencies and higher power, the magnetic core generates a large amount of heat during operation, causing the electromagnetic devices to heat up rapidly.

[0003] For example, the magnetic core structure disclosed in patent announcement CN220569490 U includes several magnetic core units evenly spaced along a first direction and a second direction. Each magnetic core unit is 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 that can cover the upper / lower surfaces of the several magnetic core units. This structure can meet the requirements of the transmitter and receiver of a wireless charging system for the magnetic core structure.

[0004] In the above, there is no buffer structure between adjacent magnetic core units, which leads to damage due to collision when subjected to external impact or vibration. This will affect the internal circuits between adjacent magnetic core units and generate electromagnetic interference. Because there is no specific structure between adjacent magnetic core units, the structural stability between adjacent magnetic core units is insufficient. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-interference magnetic core that improves the buffering effect and reduces the generation of electromagnetic interference.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An anti-interference magnetic core includes a first magnetic core unit and a second magnetic core unit, with a connector provided between the first magnetic core unit and the second magnetic core unit.

[0008] The two ends of the connector are fixed to one side of the first magnetic core unit and one side of the second magnetic core unit, respectively.

[0009] The connector includes a housing and a plug-in plate.

[0010] The housing has slots, and the insert plate is placed in the slots and movably connected to them.

[0011] The slot is equipped with several positioning posts that are fixed to the inner wall of the slot.

[0012] The insertion plate has several first limiting plates fixed to it on one side. The first limiting plates are placed between adjacent positioning posts, and the two sides of the first limiting plates are connected to the outer wall of the first limiting plate and the inner wall of the groove, respectively.

[0013] The casing is also provided with two blind slots, which are located on either side of the slot.

[0014] The plug-in board is also provided with a second limiting plate. There are two second limiting plates, which are placed on both sides of the first limiting plate so that the second limiting plates are placed in the blind groove and connected to the blind groove.

[0015] The present invention is further configured such that: a first auxiliary layer, a second auxiliary layer and several extrusion columns are fixed to the positioning column in the groove, the extrusion columns are placed between the first auxiliary layer and the second auxiliary layer, the two sides of the extrusion columns are respectively connected to the first auxiliary layer and the second auxiliary layer, and there is a buffer space between the first auxiliary layer, the second auxiliary layer and the adjacent extrusion columns.

[0016] The present invention is further configured such that the plug-in board has a buffer chamber.

[0017] The present invention is further configured such that: the first auxiliary layer, the second auxiliary layer and the plug-in plate are all made of rubber, and the extrusion column is made of polyurethane.

[0018] The present invention is further configured such that both the first limiting plate and the second limiting plate are made of silicone.

[0019] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0020] By inserting the first limiting plate between adjacent positioning posts and the second limiting plate into the blind slot, the double-insertion design enhances the buffering effect when subjected to external impacts or vibrations. Combined with the structure of the first auxiliary layer, the extrusion post, and the second auxiliary layer, the impact of external impacts on the internal circuits of the first and second magnetic core units can be reduced, thereby reducing the generation of electromagnetic interference. The use of rubber, polyurethane, and silicone buffer materials effectively improves the impact and vibration resistance between the first and second magnetic core units. The installation of connectors between the first and second magnetic core units improves the structural stability between them. Attached Figure Description

[0024] 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.

[0025] 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.

[0026] like Figure 1 As shown, the anti-interference magnetic core includes a first magnetic core unit 1 and a second magnetic core unit 2. A connector 3 is installed between the first magnetic core unit 1 and the second magnetic core unit 2. The housing 4 is fixed to the first magnetic core unit 1 with glue. The plug-in plate 5 is also glued to the second magnetic core unit 2. The plug-in plates 5 are all made of rubber, which has high elasticity and can effectively alleviate impact and vibration.

[0027] The insertion plate 5 extends into the slot 6 of the housing 4, and then the first limiting plate 8 on the insertion plate 5 extends between the adjacent positioning posts 7. There are six first limiting plates 8 and seven positioning posts 7. The six first limiting plates 8 can be inserted into the adjacent positioning posts 7 in an alternating manner, so that the outer wall of the first limiting plate 8 is in pressure contact with the outer wall of the adjacent positioning post 7 and the first auxiliary layer 11, which improves the cushioning performance. The first limiting plate 8 and the insertion plate 5 are glued together, and the positioning posts 7 are fixed to the first auxiliary layer 11 with glue.

[0028] When the insert plate 5 is in the slot 6, the second limiting plates 10 on both sides of the first limiting plate 8 are also inserted into the corresponding blind slots 9. The outer wall of the second limiting plate 10 and the inner wall of the blind slot 9 are in contact. Both the first limiting plate 8 and the second limiting plate 10 are made of silicone. Silicone has good flexibility and elasticity, and can quickly return to its original shape after being compressed, which can effectively buffer the impact force.

[0029] The slot 6 is also equipped with a first auxiliary layer 11, a second auxiliary layer 12 and an extrusion column 13. The two sides of the extrusion column 13 are respectively bonded and fixed to the first auxiliary layer 11 and the second auxiliary layer 12. When the first limiting plate 8 is squeezed between the outer wall of the adjacent positioning column 7 and the first auxiliary layer 11, the first auxiliary layer 11 will squeeze towards the extrusion column 13. At the same time, the extrusion column 13 will squeeze and buffer the first auxiliary layer 11. The first auxiliary layer 11 and the second auxiliary layer 12 are made of rubber, which can absorb and disperse vibration energy. The extrusion column 13 is made of polyurethane, which has good elasticity and buffering capacity, which can effectively reduce vibration and impact, and at the same time improve the structural stability of the extrusion column 13, making it less prone to deformation or damage.

[0030] There is a buffer space between the first auxiliary layer 11, the second auxiliary layer 12 and the adjacent extrusion column 13. When the outer wall of the first limiting plate 8 adjacent positioning column 7 is squeezed between the first auxiliary layer 11, the first limiting plate 8 faces the buffer space, which can reduce the impact of external impact on the internal circuits of the first magnetic core unit 1 and the second magnetic core unit 2, thereby reducing the generation of electromagnetic interference.

[0031] The plug-in plate 5 has a buffer chamber 14, which can alleviate the impact force when the first magnetic core unit 1 and the second magnetic core unit 2 are squeezed together.

[0032] 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.
