[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.

[0026] The embodiments of the present application will be described below in combination with Figs. 1 to 3 .

[0027] According to the embodiments of the present application, an inductor is provided, which comprises:

[0028] Two mounting plates 1, which are arranged in parallel relative to each other and have a distance between them adapted to the maximum length of the lead extending in the direction perpendicular to the axial direction;

[0029] A winding structure, which is arranged between the two mounting plates 1 and is adapted to wind the lead and form a coil thereon, and the maximum radial length of the coil is less than or equal to the maximum radial length of the mounting plate 1, so as to ensure that the two mounting plates 1 can limit the coil in the axial direction of the winding structure.

[0030] It should be noted that when the lead is a regular ordinary lead with a circular cross section, the maximum length of the lead extending in the direction perpendicular to the axial direction is the diameter of the lead; when the lead is flat or has other irregular shapes, the maximum length of the lead extending in the direction perpendicular to the axial direction is the maximum distance between two points on the cross section.

[0031] It should be noted that the two mounting plates 1 are arranged in parallel, providing a stable and regular frame for the winding structure. During winding, the coil can be wound in a relatively regular space, avoiding deviations caused by problems such as angle inclination of the mounting plate 1. At the same time, the distance between the two mounting plates 1 is adapted to the maximum length of the lead extending in the direction perpendicular to the axial direction, ensuring that the lead does not shake or deviate when winding between the mounting plates 1, affecting the tightness and uniformity of the coil; nor will the lead be difficult to pass through or be excessively pressed during winding due to the small gap, damaging the lead or affecting the winding efficiency, thereby ensuring the stability of the inductor.

[0032] The inductor provided by the embodiment provides a stable frame for winding by arranging two mounting plates 1 in parallel and with a distance adapted to the width of the lead; the winding structure therebetween facilitates winding the lead to form a coil, effectively solving the problems of difficult adhesion and uneven stacking during winding, ensuring uniform number of turns of the coil, improving the stability of the inductor and the performance of the product, meeting the demand of electronic equipment for high-performance inductors, and the maximum radial length of the coil is less than or equal to the maximum radial length of the mounting plate 1, so that the coil is clamped and fixed by the two mounting plates 1, preventing loosening.

[0033] Further, the winding structure includes at least two winding columns 2, the axial directions of the at least two winding columns 2 are arranged in parallel, and the two ends of the winding column 2 are respectively vertically abutted and fixed with the plate surfaces of the two mounting plates 1, and the lead is sequentially wound around the circumferences of the at least two winding columns 2, thereby forming a coil.

[0034] In the embodiment, the number of winding columns 2 is two, the two winding columns 2 are axially parallel and equally spaced, and they evenly share the winding task of the lead. Of course, in other embodiments, other numbers of winding columns 2 can be arranged according to actual needs, such as 3, 4 or more, and the multiple (3 or more) winding columns 2 are distributed in a ring shape to ensure the uniformity of winding. Here, the specific number of winding columns 2 is not limited.

[0035] It should be noted that the axial directions of the at least two winding columns 2 are parallel to each other, ensuring that the lead is wound along a parallel path during winding, so that each turn of the coil can be kept on a relatively parallel plane, which is beneficial to improve the uniformity and stability of the coil. The two ends of the winding column 2 are respectively vertically abutted and fixedly connected with the plate surfaces of the two mounting plates 1, which not only ensures the stability of the winding column 2 between the mounting plates 1, but also provides reliable support for the winding of the lead.

[0036] Further, the cross-sectional shape of the winding column 2 is circular.

[0037] Specifically, during winding, the lead wire can be more smoothly wound around the circumference of the circular winding column 2. Since the curvature of each point on the circular surface is the same, the operator does not need to frequently adjust the winding angle during the winding process, and only needs to maintain uniform winding strength to make the lead wire tightly and uniformly wound on the winding column 2, thereby improving the winding efficiency and the manufacturing quality of the coil. Moreover, the arc-shaped side surface can make the lead wire uniformly stressed during winding, thereby reducing the deformation or damage of the lead wire caused by uneven local stress, thereby ensuring the stability and reliability of the coil, and reducing the scratch damage to the surface of the lead wire.

[0038] In an optional embodiment, the cross-sectional shape of the winding column 2 can be a polygon, and the number of sides of the polygon is greater than or equal to 3.

[0039] It should be noted that the edges of the polygonal winding column 2 provide stable positioning points for the lead wire to prevent sliding, ensure accurate and uniform number of turns, improve the stability of inductance performance, and meet the demand of high-precision inductance value circuit. Different numbers of winding columns 2 can be selected as needed to achieve specific inductance characteristics, which is suitable for scenarios with special requirements for magnetic field distribution, and provides more possibilities for inductance diversification applications. Here, the cross-sectional shape of the winding column 2 is not limited, and the specific shape can be selected according to the application scenario of the inductance.

[0040] Further, the surface of the winding column 2 is provided with anti-slip lines, and the anti-slip lines are suitable for increasing the friction between the lead wire and the winding column 2.

[0041] As can be easily understood, the anti-slip lines increase the friction with the lead wire, effectively prevent the lead wire from sliding and shifting during winding, ensure the accuracy of the number of turns, maintain uniform and tight winding state, and improve the stability and reliability of the inductance coil.

[0042] Further, the mounting plate 1 is provided with a threading hole 11, and the threading hole 11 is suitable for threading the lead wire between the two mounting plates 1.

[0043] It should be noted that the shape of the threading hole 11 is set to be circular in this embodiment, and since it has no corners, the lead wire is not easy to be scratched when passing through, which can ensure the integrity of the conductor insulation layer and ensure electrical safety. Moreover, the circular hole is relatively simple to process, whether it is drilled, punched or injection molded, and the cost is relatively low. In terms of size, the diameter of the threading hole 11 needs to be accurately controlled, and it is usually 0.1-0.3 mm larger than the outer diameter of the lead wire. If the hole diameter is too small, the lead wire will encounter a large resistance when threading, which not only increases the operation difficulty, but also may cause the lead wire surface to wear or even be damaged, affecting the inductance performance; and if the hole diameter is too large, the lead wire is easy to shake when passing through, and it is difficult to accurately position the initial winding position, and the winding process may also deviate, causing the coil to be wound unevenly, thereby reducing the stability and reliability of the inductance.

[0044] As is easily understood, the wire hole 11 provides a precise guide path for the lead wire, allowing it to smoothly and quickly enter the winding area between the two mounting plates 1. This prevents the lead wire from wandering around outside the mounting plate 1, effectively preventing winding errors or short circuit risks caused by messy lead wire arrangement, and ensuring the orderliness and efficiency of the winding process.

[0045] Furthermore, the threading hole 11 is provided on the surface of the mounting plate 1 between the two winding posts 2.

[0046] It is easy to understand that by setting the wire hole 11 on the surface of the mounting plate 1 between the two winding posts 2, the lead wire can directly reach the winding post 2 through the wire hole 11 at this position with the shortest path without having to move a long distance. This effectively reduces the bending and twisting of the lead wire, reduces the difficulty of operation, and improves the winding efficiency.

[0047] Specifically, in this embodiment, the wire hole 11 is located at the center of the mounting plate 1, and two winding posts 2 are symmetrically distributed on opposite sides of the wire hole 11 and are arranged close to the wire hole 11 so that the lead wire can be smoothly wound on the winding post 2 after passing through the wire hole.

[0048] Furthermore, the surface of mounting plate 1 is circular.

[0049] It is easy to understand that the circular mounting plate 1 has good structural stability. Its concentricity ensures that the force distribution is uniform when subjected to external forces or electromagnetic forces, and stress concentration is less likely to occur, thus ensuring the stable operation of the inductor in complex environments. From the perspective of winding, the circular outline facilitates the uniform distribution of the winding posts 2 around the center, allowing the leads to be wound within a regular circumference during the winding process. This helps to form a uniform and symmetrical coil structure, thereby optimizing the magnetic field distribution of the inductor and improving its performance.

[0050] In an optional embodiment, the mounting plate 1 can also be rectangular. A rectangular mounting plate 1 facilitates standardized production, enabling more efficient use of raw materials during mass manufacturing, reducing waste of scrap materials, and lowering production costs. Furthermore, the rectangular shape better fits the rectangular layout on the circuit board when combined with other electronic components, facilitating overall circuit design and wiring planning.

[0051] Furthermore, multiple heat dissipation holes 12 are provided on the surface of the mounting plate 1.

[0052] It is easy to understand that multiple heat dissipation holes 12 are provided on the mounting plate 1 to effectively improve the heat dissipation performance of the inductor. When the inductor is working, the current passing through the coil generates heat. If this heat cannot be dissipated in time, the inductor temperature will rise, thus affecting its performance and lifespan. The presence of heat dissipation holes 12 provides a channel for heat transfer, allowing heat to be quickly conducted from the inside of the mounting plate 1 to the external environment, reducing the inductor's operating temperature. This not only ensures that the inductor operates within a stable temperature range, improving its reliability, but also reduces inductor parameter drift caused by temperature changes, ensuring that the inductor maintains stable electrical performance in the circuit and extending its service life in various electronic devices.

[0053] Reference Fig. 3 As shown, in this embodiment, multiple heat dissipation holes 12 are arranged in a circular pattern on the surface of the mounting plate 1. The heat dissipation holes 12 are located at the midpoint of the radius of the mounting plate 1 to ensure stable heat dissipation of the inductor. In an optional embodiment, they can also be arranged in an array on the mounting plate 1, evenly covering the effective area of ​​the mounting plate 1, ensuring that heat is dissipated evenly.

[0054] It should be noted that the specific size of the heat dissipation hole 12 is not limited here. Its size can be reasonably selected according to the size of the mounting plate 1, the thickness of the lead wire, and the heat generation of the inductor itself.

[0055] In addition, to secure the lead end of the coil at the other end after winding, adhesive or clips can be used to fix the lead end to the edge of the mounting plate 1 to prevent the lead from loosening.

[0056] This embodiment also provides a radio frequency device, including the inductor described above.
