Description

Technical Field

[0001] This application relates to the field of inductor technology, and in particular to a magnetic core anti-skew positioning component and an inductor. Background Technology

[0002] A magnetic core inductor is an inductor that uses magnetic materials as its core. The magnetic core enhances the magnetic field strength, thereby increasing the inductance and optimizing the electromagnetic performance. It is widely used in power electronics, communications, automotive electronics and other fields.

[0003] Structurally, a magnetic core inductor generally includes a coil winding, a magnetic core, and a support component. The magnetic core is generally made of materials such as ferrite. The coil winding consists of insulated wires wound on the magnetic core. The support component serves as a support structure for the magnetic core and can play a supporting role.

[0004] In existing magnetic core inductors, due to tolerance fluctuations in the manufacturing of the support components, the magnetic core can still move slightly after assembly, causing the magnetic core to tilt relative to the coil winding, resulting in a decrease in the effective permeability and inductance of the magnetic core inductor. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a magnetic core anti-skew positioning component and inductor to solve the problem of magnetic core tilting in existing magnetic core inductors.

[0006] To achieve the above-mentioned technical objectives, the first aspect of this application provides a magnetic core anti-tilt positioning component, comprising: a base and an insert plate;

[0007] The base is used for mounting the magnetic core;

[0008] The insert plate is disposed on the base, and the insert plate is provided with a pressure block;

[0009] The pressure block abuts against the magnetic core on the base to apply a downward elastic clamping force to the magnetic core.

[0010] Furthermore, the insert plate includes: a first insert plate and a second insert plate;

[0011] The base is provided with a groove for mounting the magnetic core;

[0012] The first insert plate and the second insert plate are respectively disposed on both sides of the groove along the first direction on the horizontal plane;

[0013] The pressure block is disposed on the first insert plate and / or the second insert plate.

[0014] Furthermore, the base is provided with two limiting grooves;

[0015] The two limiting grooves are disposed on both sides of the groove along the first direction;

[0016] The first insert plate and the second insert plate are detachably disposed in the two limiting grooves.

[0017] Furthermore, both the first insert plate and the second insert plate are provided with protrusions;

[0018] The protrusion is inserted into the limiting groove in a horizontal direction;

[0019] The protrusion is used to restrict the movement of the first insert or the second insert in the vertical direction.

[0020] Furthermore, the first insert plate and the second insert plate are interlocked with each other.

[0021] Furthermore, a first card block is provided on the first insert plate;

[0022] The second insert plate is provided with a second card block;

[0023] The first and second locking blocks engage with each other to restrict the movement of the first and second insert plates along the first direction.

[0024] Furthermore, a first baffle is provided on the first insert plate;

[0025] The second insert plate is provided with a second baffle plate;

[0026] The end face of the first baffle along the second direction abuts against the end face of the second baffle along the second direction;

[0027] The second direction is a direction perpendicular to the first direction on a horizontal plane.

[0028] Furthermore, the pressure block is an arc-shaped rod with a concave bottom surface.

[0029] A second aspect of this application provides an inductor, comprising the magnetic core anti-skew positioning component, magnetic core, and coil winding as described in any of the preceding claims;

[0030] The magnetic core is disposed in the base of the magnetic core anti-tilt positioning assembly;

[0031] The coil winding is wound on the magnetic core.

[0032] Furthermore, the base is provided with perforations;

[0033] The coil winding passes through the through hole.

[0034] As can be seen from the above technical solutions, this application provides a magnetic core anti-skew positioning component and an inductor; wherein, the magnetic core anti-skew positioning component includes: a base and an insert plate; the base is used for mounting the magnetic core; the insert plate is disposed on the base, and a pressure block is disposed on the insert plate; the pressure block abuts against the magnetic core on the base, and is used to apply a downward elastic clamping force to the magnetic core.

[0035] In this solution, after the magnetic core is installed on the base, the insert plate can apply a clamping force to the magnetic core through the pressure block. This ensures that even if there are dimensional tolerance fluctuations between the base and the insert plate, the insert plate can still fit tightly against the magnetic core, thus positioning the magnetic core and preventing tilting, thereby reducing the offset caused by dimensional tolerances after the magnetic core is installed.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0047] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "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 the embodiments of this application 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 the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0049] Please see Figures 1 to 3 The first aspect provided in this application provides a magnetic core anti-tilting positioning component, including: a base 10 and an insert plate 20; the base 10 is used for mounting a magnetic core 30; the insert plate 20 is disposed on the base 10, and a pressure block 201 is disposed on the insert plate 20; the pressure block 201 abuts against the magnetic core 30 on the base 10 and is used to apply a downward elastic clamping force to the magnetic core 30.

[0050] In this embodiment, the method of installing the magnetic core 30 and the base 10 can refer to existing technology, specifically ensuring that the magnetic core 30 can be installed on the base 10. Since there will inevitably be dimensional tolerances between the base 10 and the magnetic core 30 during the manufacturing process, the magnetic core 30 will still have a certain amount of room to move after installation, which will cause the magnetic core 30 to tilt slightly.

[0051] After the magnetic core 30 is installed, the insert plate 20 is mounted on the base 10 to abut against the magnetic core 30 and provides downward clamping force to the magnetic core 30 through the pressure block 201, thereby reducing the risk of the magnetic core 30 shifting relative to the base 10 and preventing the magnetic core 30 from tilting. Furthermore, because the pressure block 201 is elastic, even in extreme cases where the magnetic core 30 and the base 10 are at the upper or lower tolerance limits, the pressure block 201 can still remain firmly against the magnetic core 30, providing stable support.

[0052] In one implementation, the pressure block 201 can be an elastic block disposed on the insert plate 20; the material of the pressure block 201 can be an elastic soft material such as rubber or silicone. After the magnetic core 30 and the insert plate 20 are installed in sequence, the pressure block 201 abuts against the magnetic core 30 to provide clamping force.

[0053] In another embodiment, the clamping block 201 can be a plastic rod-shaped structure and integrated with the insert plate 20; that is, the insert plate 20 is a plastic plate structure. The insert plate 20 and the clamping block 201 can be made of elastic plastic materials such as thermoplastic polyurethane. The integrated structure of the insert plate 20 and the clamping block 201 is easier to manufacture, and compared to flexible soft materials, the plastic rod structure of the clamping block 201 can provide a more stable elastic clamping force to the magnetic core 30. A cross-sectional view of the clamping block 201 clamping the magnetic core 30 can be found in [reference needed]. Figure 3 After being pressed, the pressure block 201 adheres tightly to the upper surface of the magnetic core 30.

[0054] In a more specific embodiment, please refer to Figures 1 to 4 The insertion plate 20 includes: a first insertion plate 21 and a second insertion plate 22; a groove 11 for mounting the magnetic core 30 is provided on the base 10; the first insertion plate 21 and the second insertion plate 22 are respectively disposed on both sides of the groove 11 along the first direction x on the horizontal plane; and the pressure block 201 is disposed on the first insertion plate 21 and / or the second insertion plate 22.

[0055] In this embodiment, the first direction x can be Figure 1 and Figure 4 The x-axis direction is shown. The method of installing the first insert plate 21 and the second insert plate 22 from both sides of the first x-axis direction enables the insert plate 20 to be fixed after the magnetic core 30 is installed, so as to ensure the pressing effect of the insert plate 20 on the magnetic core 30.

[0056] In one implementation, the pressure block 201 may be provided only on the first insert plate 21 or the second insert plate 22.

[0057] In another embodiment, both the first insert plate 21 and the second insert plate 22 are provided with pressure blocks 201, so that the magnetic core 30 can be pressed tightly on both sides, thereby improving the pressing effect on the magnetic core 30.

[0058] In one embodiment, the base 10 is provided with two limiting grooves 12; the two limiting grooves 12 are provided on both sides of the groove 11 along the first direction; the first insert plate 21 and the second insert plate 22 are respectively detachably provided in the two limiting grooves 12.

[0059] The limiting groove 12 allows for quick installation of the first insert plate 21 and the second insert plate 22, improving installation efficiency. Simultaneously, the positions of the limiting groove 12 and the recess 11 are pre-set on the base 10, so the first insert plate 21 and the second insert plate 22 can be installed according to the position set by the limiting groove 12, ensuring precise alignment between the insert plate 20 and the magnetic core 30, thereby ensuring the clamping effect of the insert plate 20 on the magnetic core 30.

[0060] In this embodiment, the limiting groove 12 can open in a horizontal direction, specifically in the first direction x; the first insert plate 21 and the second insert plate 22 can be inserted into the limiting groove 12 along the first direction x. The limiting groove 12 can restrict the movement of the first insert plate 21 and the second insert plate 22 along the second direction y, ensuring that they will not shift during installation, thus stabilizing the relative position of the insert plate 20 and the magnetic core 30. Here, the second direction y is a direction perpendicular to the first direction x on a horizontal plane.

[0061] Optionally, both the first insert plate 21 and the second insert plate 22 are provided with protrusions 202; the protrusions 202 are inserted into the limiting groove 12 in the horizontal direction; the protrusions 202 are used to restrict the first insert plate 21 or the second insert plate 22 from moving in the vertical direction.

[0062] In this embodiment, the protrusion 202 protrudes in the horizontal direction, so that the insert plate 20 and the limiting groove 12 form a limiting fit, thereby effectively fixing the first insert plate 21 and the second insert plate 22 in the vertical direction and preventing them from moving up and down during use.

[0063] In one embodiment, the first insert plate 21 and the second insert plate 22 are interlocked with each other. That is, in addition to being inserted into the limiting groove 12, the first insert plate 21 and the second insert plate 22 are also connected to each other by a snap-fit, which enhances the stability of the overall structure of the insert plate 20 and further ensures that the magnetic core 30 remains stable during operation.

[0064] In one specific embodiment, a first locking block 23 is provided on the first insert plate 21; a second locking block 24 is provided on the second insert plate 22; the first locking block 23 and the second locking block 24 are engaged with each other to restrict the movement of the first insert plate 21 and the second insert plate 22 along the first direction.

[0065] In this embodiment, the first locking block 23 and the second locking block 24 can be hook-type structures. The insert plate 20 is entirely made of plastic sheet. Specifically, the first locking block 23 and the pressing block 201 cause the first insert plate 21 to form an F-shaped structure; the second locking block 24 and the pressing block 201 cause the second insert plate 22 to form an F-shaped structure. The insert plate 20, made of plastic sheet material, has a certain degree of elasticity, so the first locking block 23 and the second locking block 24 can deform and eventually lock together after they approach and abut against each other, realizing the locking of the first insert plate 21 and the second insert plate 22.

[0066] In one embodiment, a first baffle 25 is provided on the first insert plate 21; a second baffle 26 is provided on the second insert plate 22; the end face of the first baffle 25 along the second direction y abuts against the end face of the second baffle 26 along the second direction.

[0067] The first baffle 25 and the second baffle 26 form a blockage in the second direction y. Together with the above-mentioned snap-fit ​​structure, they can prevent the first insert plate 21 and the second insert plate 22 from being displaced relative to each other in the y-axis direction, further enhancing the overall stability of the insert plate 20.

[0068] In the embodiments provided in this application, the pressure block 201 is an arc-shaped rod with a concave bottom surface, so that the pressure block 201 can fit the circular magnetic core 30. Correspondingly, the groove 11 is an arc-shaped groove.

[0069] Please see Figure 1 and Figure 2 The second aspect of this application provides an inductor, including a magnetic core anti-skew positioning assembly, a magnetic core 30, and a coil winding 40 as described above; the magnetic core 30 is disposed on a base 10 in the magnetic core anti-skew positioning assembly; and the coil winding 40 is wound on the magnetic core 30.

[0070] The base 10 has a through hole 13; the coil winding 40 passes through the through hole 13 to increase the stability of the connection between the coil winding 40, the magnetic core 30 and the base 10.

[0071] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
