Description

Technical Field

[0001] The present application relates to the field of inductance technology, and in particular to an adjustable inductance device and electronic equipment. Background Art

[0002] Inductors, known for their energy storage, filtering, and impedance matching capabilities, are widely used in electronic devices such as impedance matchers and filters. Inductors are particularly important in impedance matchers, primarily used to adjust the circuit's impedance characteristics to achieve efficient power transmission between the signal source and the load and reduce signal reflections. Inductors play multiple roles in filters and are an indispensable component of filtering circuits. Their primary functions include blocking high-frequency signals, allowing low-frequency signals to pass, suppressing ripple signals in power supplies, filtering out high-frequency noise, and creating a time delay effect.

[0003] However, due to the combined influence of factors such as manufacturing errors, installation tolerances, transportation vibrations, and changes in operating and ambient temperatures, inductors suffer from low precision, poor stability, and poor consistency of inductors within the same batch in practical applications. Therefore, this application proposes an adjustable inductor device and electronic device. Summary of the Invention

[0004] The present application discloses an adjustable inductance device and an electronic device, which are used to solve the technical problems of low inductance precision, poor stability, and poor consistency of inductance in the same batch.

[0005] In a first aspect, the present application provides an adjustable inductor device, comprising:

[0006] An inductor coil is formed by winding a conducting wire and is in a spiral shape, and the inductor coil includes at least two turns of coil;

[0007] An adjusting mechanism, used to adjust the inductance value of the inductor coil; the adjusting mechanism comprises:

[0008] a connecting component connected to the inductor coil;

[0009] an adjusting member connected to the connecting assembly and rotatably arranged;

[0010] When the adjusting member is rotated, the adjusting member drives at least two adjacent turns of the coil to move relative to each other along the axial direction of the inductor coil, so as to change the inductance value of the inductor coil.

[0011] By setting up an adjustment mechanism and the adjustment mechanism including a connecting component and an adjustment part, when the adjustment part is rotated, at least two adjacent turns of the coil can be relatively moved along the axial direction of the inductor coil, thereby changing the inductance value of the inductor coil. By rotating the adjustment part, the inductance value of the inductor coil can be adjusted within a certain range. The inductance value of the inductor coil can be calibrated through adjustment to achieve high consistency in the inductance values ​​of the inductor coils in the same batch, reduce the influence of the inductor coil processing deviation, mechanical vibration and ambient temperature on the inductance value of the inductor coil, improve the accuracy and stability of the inductance value of the inductor coil, and ensure the consistency of the inductance value of the inductor coils in the same batch.

[0012] In one possible implementation, the connection component includes:

[0013] A support block is provided on the outer side of the inductor coil in a circumferential direction, and a first guide surface is provided on the support block;

[0014] a pressing block connected to the inductor coil, the pressing block being connected to the supporting block via the adjusting member, and the pressing block being in sliding contact with the first guide surface;

[0015] When the adjusting member is rotated, the pressing block moves simultaneously along the first direction and the axial direction of the inductor coil under the guidance of the first guide surface to change the axial length of the inductor coil, and the first direction is set at an angle to the axial direction of the inductor coil.

[0016] The connection assembly includes a support block and a pressure block, so that when the adjustment member is rotated, the pressure block drives the inductor coil to move. The connection assembly is easy to operate and has low cost.

[0017] In a possible embodiment, there are at least two pressing blocks, a portion of the pressing blocks are first-type pressing blocks, and another portion of the pressing blocks are second-type pressing blocks;

[0018] There are at least two adjusting members, a portion of which are the first type of adjusting members, and another portion of which are the second type of adjusting members; the first type of adjusting members connects the first type of pressing block and the support block, and the second type of adjusting members connects the second type of pressing block and the support block;

[0019] There are two first guide surfaces, which are spaced apart along the axial direction of the inductor coil and are in sliding contact with the first type of pressing block and the second type of pressing block respectively;

[0020] The inductor coil has a first coil end and a second coil end which are arranged opposite to each other in the axial direction of the inductor coil;

[0021] When the first type of adjusting member is rotated, the first type of pressing block approaches the support block along the first direction and approaches the second end of the coil along the axial direction of the inductor coil, or the first type of pressing block moves away from the support block along the first direction and moves away from the second end of the coil along the axial direction of the inductor coil;

[0022] When the second type of adjusting member is rotated, the second type of pressing block approaches the support block along the first direction and approaches the first end of the coil along the axial direction of the inductor coil, or the second type of pressing block moves away from the support block along the first direction and moves away from the first end of the coil along the axial direction of the inductor coil.

[0023] The pressure blocks include first-type pressure blocks and second-type pressure blocks, which can adjust the axial length of the inductor coil at both ends of the axial direction of the inductor coil, increase the adjustment range of the inductance value of the inductor coil, improve the accuracy and stability of the inductance value of the inductor coil, and ensure the consistency of the inductance value of the inductor coils in the same batch.

[0025] Since the adjusting piece is threadedly connected to the pressing block, and when the adjusting piece rotates, the pressing block is displaced in the axial direction of the inductor coil, it is set that when the adjusting piece rotates, the adjusting piece moves along the axial direction of the inductor coil in the first through hole, which can ensure the consistency of the position of the adjusting piece and the pressing block, avoid the position of the adjusting piece blocking the movement of the pressing block, and ensure the stable expansion and contraction of the inductor coil.

[0140] Inductors, known for their energy storage, filtering, and impedance matching capabilities, are widely used in electronic devices such as impedance matchers and filters. Inductors are particularly important in impedance matchers, primarily used to adjust the circuit's impedance characteristics to achieve efficient power transmission between the signal source and the load and reduce signal reflections. Inductors play multiple roles in filters and are an indispensable component of filtering circuits. Their primary functions include blocking high-frequency signals, allowing low-frequency signals to pass, suppressing ripple signals in power supplies, filtering out high-frequency noise, and creating a time delay effect.

[0141] In related technologies, inductors used in electronic devices such as impedance matchers and filters utilize fixed hollow coil structures, with their inductance values ​​being fixed, non-adjustable parameters. However, due to factors such as manufacturing errors, installation tolerances, transportation vibrations, and variations in operating and ambient temperatures, inductors suffer from low precision, poor stability, and inconsistent inductance across batches in practical applications.

[0142] Based on the above technical problems, the present application proposes an adjustable inductance device, which includes an inductance coil and an adjustment mechanism. The inductance coil is formed by winding a wire and is spiral-shaped. The inductance coil includes at least two turns of coil; the adjustment mechanism includes a connecting assembly and an adjustment member. The connecting assembly is connected to the inductance coil; the adjustment member is connected to the connecting assembly and is rotatably arranged; wherein, when the adjustment member is rotated, the adjustment member drives at least part of the two adjacent turns of coil to move relative to each other along the axial direction of the inductance coil to change the inductance value of the inductance coil; the inductance value of the inductance coil can be adjusted within a certain range, and the inductance value of the inductance coil can be calibrated by adjustment, so as to achieve a high degree of consistency in the inductance value of the inductance coils of the same batch, reduce the influence of the inductance coil processing deviation, mechanical vibration and ambient temperature on the inductance value of the inductance coil, improve the accuracy and stability of the inductance value of the inductance coil, and ensure the consistency of the inductance value of the inductance coils of the same batch.

[0147] Adjustment mechanism 2 may include an adjustment member 21. Adjustment member 21 is connected to connection assembly 22 and is rotatably disposed. Rotation of adjustment member 21 causes at least two adjacent turns of the inductor 1 to move relative to each other along the axial direction of the inductor 1, thereby changing the inductance of the inductor 1.

[0149] Example 2

[0150] Based on the first embodiment, this embodiment mainly describes a connection component 22. In this embodiment, the connection component 22 may be a first connection component 221.

[0151] refer to Figure 1 、 Figure 2 and Figure 3, the connecting component 22 may include a support block 2211. The support block 2211 may be arranged on the outer side of the inductor coil 1 in the circumferential direction. A first guide surface 22111 may be provided on the support block 2211. The connecting component 22 may include a pressure block 2212. The pressure block 2212 may be connected to the inductor coil 1. The pressure block 2212 and the support block 2211 may be connected through an adjusting member 21. The pressure block 2212 is in sliding contact with the first guide surface 22111. When the adjusting member 21 is rotated, the pressure block 2212 is guided by the first guide surface 22111, and the pressure block 2212 moves simultaneously along the first direction and the axial direction of the inductor coil 1 to change the axial length of the inductor coil 1. The first direction is set at an angle to the axial direction of the inductor coil 1. The connecting component is provided to include a support block and a pressure block, so that when the adjusting member is rotated, the pressure block can drive the inductor coil to move. The connecting component is easy to operate and has low cost.

[0152] Specifically, the first direction can be perpendicular to the axial direction of the inductor coil 1. The first direction can be the radial direction of the inductor coil 1. The first guide surface 22111 can be a plane. When the first guide surface 22111 is a plane, the first guide surface 22111 is tilted relative to the axial direction of the inductor coil 1, and the angle between the axial direction of the inductor coil 1 and the first guide surface 22111 is an acute angle.

[0153] The adjusting member 21 can be threadedly connected to the pressing block 2212. The support block 2211 can be provided with a first through hole 22112. The first through hole 22112 penetrates the support block 2211. The adjusting member 21 is inserted into the first through hole 22112. When the adjusting member 21 rotates, the adjusting member 21 moves in the first through hole 22112 along the axial direction of the inductor 1.

[0154] Specifically, the first through hole 22112 may be a waist-shaped hole. The rotation axis of the adjusting member 21 may be parallel to the first direction, and the first direction may be perpendicular to the axial direction of the inductor 1. The adjusting member 21 may be a screw.

[0155] refer to Figure 1 、 Figure 2 and Figure 3 The plurality of pressing blocks 2212 may include at least two pressing blocks, with some of the pressing blocks 2212 being first-type pressing blocks 22121 and others being second-type pressing blocks 22122. The inductor 1 is connected to the first-type pressing blocks 22121 and the second-type pressing blocks 22122. The inductor 1 includes a first coil end 11 and a second coil end 12 that are disposed opposite each other in the axial direction of the inductor 1.

[0156] There are at least two adjusting members 21, a part of the adjusting members 21 are first-type adjusting members 211, and another part of the adjusting members 21 are second-type adjusting members 212. The first-type adjusting members 211 connect the first-type pressing block 22121 and the support block 2211, and the second-type adjusting members 212 connect the second-type pressing block 22122 and the support block 2211.

[0157] There are two first guide surfaces 22111. The two first guide surfaces 22111 are spaced apart along the axial direction of the inductor 1. The two first guide surfaces 22111 are in sliding contact with the first type of pressing block 22121 and the second type of pressing block 22122 respectively.

[0158] When the first type adjusting member 211 is rotated, the first type pressing block 22121 approaches the supporting block 2211 along the first direction and approaches the second end 12 of the coil along the axial direction of the inductor coil 1, or the first type pressing block 22121 moves away from the supporting block 2211 along the first direction and moves away from the second end 12 of the coil along the axial direction of the inductor coil 1.

[0159] When the second type adjusting member 212 is rotated, the second type pressing block 22122 approaches the support block 2211 along the first direction and approaches the first end 11 of the coil along the axial direction of the inductor coil 1, or the second type pressing block 22122 moves away from the support block 2211 along the first direction and moves away from the first end 11 of the coil along the axial direction of the inductor coil 1.

[0160] The pressure block 2212 is provided to include a first type of pressure block 22121 and a second type of pressure block 22122, which can adjust the axial length of the inductor coil 1 at both ends of the axial direction of the inductor coil 1, thereby increasing the adjustment range of the inductance value of the inductor coil 1, improving the accuracy and stability of the inductance value of the inductor coil 1, and ensuring the consistency of the inductance value of the inductor coils 1 in the same batch.

[0161] Specifically, the first type of pressing block 22121 is connected to the first end of the inductor 1 , and the second type of pressing block 22122 is connected to the second end of the inductor 1 .

[0162] The first type of adjusting member 211 and the first type of pressing block 22121 can be threadedly connected. The first type of adjusting member 211 is inserted into the first through hole 22112. When the first type of adjusting member 211 rotates, the first type of adjusting member 211 moves along the axial direction of the inductor 1 in the first through hole 22112. The rotation axis of the first type of adjusting member 211 is parallel to the first direction, and the first direction is perpendicular to the axial direction of the inductor 1. Since the adjusting member is threadedly connected to the pressing block, and when the adjusting member rotates, the pressing block is displaced in the axial direction of the inductor, and when the adjusting member rotates, the adjusting member is arranged to move along the axial direction of the inductor in the first through hole. This ensures that the position of the adjusting member is consistent with the pressing block, avoids the position of the adjusting member blocking the movement of the pressing block, and ensures stable expansion and contraction of the inductor.

[0163] The second-type adjusting member 212 can be threadedly connected to the second-type pressing block 22122. The second-type adjusting member 212 is inserted into the first through-hole 22112. When the second-type adjusting member 212 rotates, it moves axially within the first through-hole 22112 along the inductor 1. The rotation axis of the second-type adjusting member 212 is parallel to the first direction, which is perpendicular to the axial direction of the inductor 1.

[0164] When there are two first guide surfaces 22111, the two first guide surfaces 22111 are inclined in opposite directions relative to the axial direction of the inductor coil 1. A first slot 22113 may be provided on the side of the support block 2211 close to the inductor coil 1. The pressure block 2212 may be inserted into the first slot 22113. The first guide surface 22111 may be a side wall of the first slot 22113. The first guide surface 22111 is located at the end of the first slot 22113 in the axial direction of the inductor coil 1. The first type of pressure block 22121 and the second type of pressure block 22122 may both be inserted into the first slot 22113, and the two first guide surfaces 22111 may be respectively located at the two ends of the first slot 22113 in the axial direction of the inductor coil 1.

[0165] refer to Figure 1 、 Figure 2 and Figure 3 The pressing block 2212 may include a pressing plate 22123, a first limiting plate 22124, and a second limiting plate 22125. The first limiting plate 22124 and the second limiting plate 22125 are located on the side of the pressing plate 22123 close to the support block 2211. The pressing plate 22123, the first limiting plate 22124, and the second limiting plate 22125 form a limiting groove 22126. The inductor coil 1 is sleeved on the pressing plate 22123, and the coil of the inductor coil 1 is inserted into the limiting groove 22126. The limiting groove 22126 is provided so that the coil of the inductor coil 1 is inserted into the limiting groove 22126, facilitating the connection between the inductor coil 1 and the pressing block 2212.

[0166] The first limiting plate 22124 is formed with a first mating surface 221241 that is in sliding contact with the first guide surface 22111. The first mating surface 221241 may be a plane. The first mating surface 221241 and the first guide surface 22111 that are in sliding contact may be parallel.

[0167] A direction perpendicular to both the axial direction of the inductor 1 and the first direction is defined as a second direction. The second direction is parallel to the first guide surface 22111. The second direction is parallel to the first mating surface 221241.

[0168] refer to Figure 1 、 Figure 2 and Figure 3The connecting assembly 22 further includes a self-locking member 2213, which is used to securely connect the adjusting member 21 to the support block 2211. After the axial length of the inductor 1 is adjusted and determined, the self-locking member 2213 can be set to securely connect the adjusting member 21 to the support block 2211. This restricts the rotation and sliding of the adjusting member 21 relative to the support block 2211, preventing the pressing block 2212 from moving relative to the support block 2211. This maintains the axial length of the inductor 1, thereby ensuring a stable inductance value of the inductor 1.

[0169] The self-locking member 2213 is sleeved on the adjusting member 21, and the self-locking member 2213 and the adjusting member 21 can be threadedly connected. The self-locking member 2213 is located between the support block 2211 and the pressing block 2212. The self-locking member 2213 can be a self-locking nut. The self-locking nut can be a hexagonal nut.

[0170] refer to Figure 1 、 Figure 2 and Figure 3 The connecting assembly 22 may include a gasket 2214, which is sleeved on the adjusting member 21 and located on the side of the support block 2211 away from the pressing block 2212. The provision of the gasket 2214 can expand the contact area between the adjusting member 21 and the support block 2211, effectively dispersing the concentrated load of the adjusting member 21 on the support block 2211. Furthermore, the elastic deformation of the gasket 2214 can be utilized to enhance the effect of the self-locking member 2213 in securing the connection between the adjusting member 21 and the support block 2211.

When the adjusting member 21 is rotated, under the limit of the first limiting portion 22214, the first connecting member 2222 drives the first end 11 of the coil and the second end 12 of the coil to approach each other to reduce the axial length of the inductor 1, or, the first connecting member 2222 drives the first end 11 of the coil and the second end 12 of the coil away from each other to increase the axial length of the inductor 1.

[0175] Specifically, the first limiting portion 22214 is a flat surface. The axial direction of the inductor 1 is perpendicular to the first limiting portion 22214. Setting the axial direction of the inductor 1 perpendicular to the first limiting portion 22214 ensures that the first limiting portion 22214 can limit the position of the inductor 1 regardless of how the inductor 1 rotates relative to the base 2221.

The second connecting member 2224 is connected to the adjusting member 21. The second connecting member 2224 confines the terminal block 2223 to the adjusting member 21. The provision of the terminal block 2223 and the electrical connection of the terminal block 2223 to the inductor 1 through the first connecting member 2222 facilitate the electrical connection of the inductor 1 to other components through the terminal block 2223.
