Description

Technical Field

[0001] This utility model relates to the technical field of fully automated winding equipment, and in particular to a magnetic ring clamping device and a winding machine. Background Technology

[0002] A winding machine is an automated processing device that winds wire onto a magnetic ring to form a coil. The winding machine requires both mechanical transmission and electrical control to rotate the magnetic ring and to wind the wire around the inside and outside of the magnetic ring. Winding machines enable the batch and fully automated processing of common-mode inductors, significantly improving the efficiency and quality of inductor manufacturing. With the continuous development of winding machine technology, more and more inductors of different models and functions can be processed fully automatically.

[0003] Single-winding differential-mode inductors use a single wire wound around a magnetic ring to form a coil structure. Therefore, during the winding process, it is necessary to ensure the uniformity and continuity of the wire winding on the outside of the magnetic ring. However, the magnetic ring clamping device on traditional winding machines often occupies a portion of the magnetic ring space when clamping the magnetic ring from both sides of the center. This causes the coil to break at the area where the magnetic ring clamping device is located, or the adjacent wires are far apart at this point. The gaps on both sides of the coil are clearly visible, which affects the processing quality of the single-winding differential-mode inductor. Utility Model Content

[0004] The purpose of this invention is to solve the shortcomings of existing winding machines when processing single-winding differential mode inductors, where the wire is loosely wound in the clamping area of ​​the magnetic ring in the magnetic ring clamping device, resulting in gaps in the coil and an inability to maintain the continuity and consistency of the coil in the circumferential direction of the magnetic ring. This invention provides a magnetic ring clamping device that, while ensuring precise and stable clamping of the magnetic ring, minimizes the gaps in the coil to improve processing quality.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a magnetic ring clamping device, including a mounting base and a first magnetic ring clamping assembly disposed on the mounting base for clamping the two circumferential ends of a magnetic ring; the first magnetic ring clamping assembly includes a pair of magnetic ring clamps and a first driving assembly for driving the pair of magnetic ring clamps to move towards each other or away from each other; the magnetic ring clamps include a first abutting part that can abut against the outer circumferential surface of the magnetic ring and a pair of second abutting parts that extend toward the center of the magnetic ring and can abut against the axial end of the magnetic ring, the width of the second abutting part of the magnetic ring clamp on the axial end face of the magnetic ring is 0.3mm-10mm.

[0006] In one embodiment, the second abutment portions of the pair of magnetic ring clamps have different widths on the axial end faces of the magnetic rings.

[0007] In one embodiment, a wire is wound around the magnetic ring to form a continuous coil from the start end to the end end. The width of the second abutment portion of the magnetic ring clamp near the start end or end end of the coil is L1, and the width of the second abutment portion of the magnetic ring clamp located in the middle section of the coil is L2, satisfying the relationship: L1 > L2.

[0008] In one embodiment, the width L1 of the second abutment portion of the magnetic ring clamp is 1mm-20mm; the width L2 of the second abutment portion of the magnetic ring clamp is 0.3mm-5mm.

[0009] In one embodiment, the second abutting portions of the pair of magnetic ring clamps have the same width on the axial end face of the magnetic ring.

[0010] In one embodiment, the width of the second abutting portion of the pair of magnetic ring clamps on the axial end face of the magnetic ring is 0.3mm-10mm.

[0011] In one embodiment, the magnetic ring clamping device further includes a second magnetic ring clamping assembly for clamping both axial ends of the magnetic ring and a translation assembly disposed on the mounting base for driving the second magnetic ring clamping assembly to move horizontally to the magnetic ring.

[0012] In one embodiment, the second magnetic ring assembly includes a pair of clamping plates and a second driving assembly for driving the pair of clamping plates to move toward each other or away from each other. When the pair of clamping plates move toward each other, they respectively abut against two end faces axially of the magnetic ring.

[0013] In one embodiment, when the pair of magnetic ring clamps of the first magnetic ring clamping assembly clamps the magnetic ring, they divide the magnetic ring into a winding region and a non-winding region, and the pair of clamping pieces of the second magnetic ring clamping assembly clamp the non-winding region of the magnetic ring.

[0014] The beneficial effects of the magnetic ring clamping device provided by this utility model are as follows: the first magnetic ring clamping assembly in the magnetic ring clamps and fixes the magnetic ring from both sides of the circumference of the magnetic ring. The winding area is restricted by a pair of magnetic ring clamps, ensuring that the unit wire is wound within the specified area, so as to ensure that the density and tightness of the coil meet the design requirements. The pair of magnetic ring clamps in the first magnetic ring clamping assembly are respectively located on both sides of the circumference of the magnetic ring, and the width of the second abutment part of the magnetic ring clamp is 0.3mm-20mm. By controlling the width of the second abutment part, it is suitable for different inductor processing applications. When winding a single coil inductor, the space occupied by the magnetic ring clamp in the magnetic ring winding position is minimized, and the influence of the magnetic ring clamp on the wire winding is reduced, thereby ensuring the uniformity and consistency of the coil when winding on the magnetic ring, so as to improve the winding quality.

[0015] This utility model also provides a winding machine, including a mounting plate, a rotating platform disposed on the mounting plate, and the aforementioned magnetic ring clamping device, wherein the mounting base of the magnetic ring clamping device is fixed on the rotating platform and rotates around the central axis of the magnetic ring.

[0016] The beneficial effects of the winding machine provided by this utility model are as follows: by adopting the above-mentioned magnetic ring clamping device, the winding machine can not only be used for processing traditional common mode inductors and dual-winding differential mode inductors, but also clamping and driving the magnetic ring to rotate during the winding process, making it more suitable for single-winding differential mode inductors. This better improves the coil winding quality of single-winding differential mode inductors, avoids gaps in the coil on the magnetic ring, and maintains the continuity and uniformity of the coil.

[0031] See Figures 1-6 This invention provides a magnetic ring clamping device 10. The magnetic ring clamping device 10 provided by this invention is used in a winding machine 100 to clamp and fix the magnetic ring 20, ensuring that other components of the winding machine 100 can drive the wire to shuttle between the outside and inside of the magnetic ring 20, so as to complete the winding of the wire on the circumference of the magnetic ring 20.

[0032] like Figures 1-6As shown, the magnetic ring clamping device 10 provided by this utility model has three different working states. Among them, as Figure 1 The diagram shown is a three-dimensional structural schematic of the magnetic ring clamping device 10 provided by this utility model clamping the magnetic ring 20 in a first state. In the first state, the first magnetic ring clamping assembly 12 in the magnetic ring clamping device 10 clamps both sides of the magnetic ring 20 in the circumferential direction to fix the magnetic ring 20. Figure 3 The image shows a top view of the magnetic ring clamping device 10 provided by this invention clamping a magnetic ring 20 in a second state. In the second state, both the first magnetic ring clamping assembly 12 and the second magnetic ring clamping assembly 13 of the magnetic ring clamping device 10 clamp the magnetic ring. The first magnetic ring clamping assembly 12 still clamps both sides of the magnetic ring 20 in the circumferential direction, while the second magnetic ring clamping assembly 13 clamps both sides of the magnetic ring 20 in the axial direction, further providing a more stable clamping for the magnetic ring 20. Figure 5 The diagram shown is a three-dimensional structural schematic of the magnetic ring clamping device 10 provided by this utility model without clamping the magnetic ring 20. In the unclamped state, both the first magnetic ring clamping assembly 12 and the second magnetic ring clamping assembly 13 are open and away from the magnetic ring 20, so that the magnetic ring 20 can be removed from the magnetic ring clamping device 10.

[0033] Furthermore, through Figures 1-6 The magnetic ring clamping device 10 provided by this utility model will be described in detail. For example... Figure 1 As shown, the magnetic ring clamping device 10 provided by this utility model includes a mounting base 11 and a first magnetic ring clamping assembly 12 disposed on the mounting base 11 for clamping the circumferential ends of the magnetic ring 20. The mounting base 11 is located below the entire magnetic ring clamping device 10 and is used to support and fix the first magnetic ring clamping assembly 12 and to fix the first magnetic ring clamping assembly 12 to other driving components of the winding machine 100. The first magnetic ring clamping assembly 12 is used to fix and support the magnetic ring 20 during the winding process of the winding machine 100, so that the magnetic ring 20 can complete the winding of the wire in a stable state, preventing the magnetic ring 20 from loosening from the magnetic ring clamping device 10, and also avoiding the wire from shaking due to the movement of the wire during the winding process, which would prevent the wire from being tightly wound.

[0034] like Figure 1 and Figure 2As shown, the first magnetic ring clamping assembly 12 includes a pair of magnetic ring clamps (121, 122) and a first driving assembly 123 for driving the pair of magnetic ring clamps 122 to move towards each other or away from each other. The first driving assembly 123 includes a driving component and a pair of sliding blocks, etc. A sliding guide rail or similar structure can be provided on the pair of sliding blocks, allowing the sliding blocks to move relative to each other under the drive of the sliding component. The first driving assembly 123 is fixed to the mounting base 11 and realizes the control and driving function for the pair of magnetic ring clamps (121, 122). The pair of magnetic ring clamps (121, 122) provided by this invention, at the maximum width in the circumferential direction of the magnetic ring 20, when the pair of magnetic ring clamps (121, 122) fixes the magnetic ring 20, the magnetic ring 20 is divided into a winding region 21 and a non-winding region 22. The winding region 21 is located on the side away from the first magnetic ring clamping assembly 12, and the non-winding region 22 is located within the area enclosed by the pair of magnetic ring clamps (121, 122). By fixing the magnetic rings with a pair of magnetic ring clamps (121, 122), the winding area in the winding machine 100 can be defined, ensuring that the wire winding density within the unit area of ​​the magnetic ring 20 meets the design requirements, avoiding the situation where the wire winding is loose on one side and tight on the other, and better ensuring that the coil density remains consistent.

[0035] like Figure 3 As shown, when the pair of magnetic ring clamps (121, 122) move towards each other, they completely abut against the magnetic ring 20, thus achieving fixation with the magnetic ring 20. Figure 5 As shown, when a pair of magnetic ring clamps (121, 122) move toward each other, they completely separate from the magnetic ring 20, thus achieving separation from the magnetic ring 20.

[0036] like Figure 6 The diagram shows a three-dimensional structural schematic of the magnetic ring clamp 122 in the first magnetic ring clamp assembly 12 provided by this utility model. The magnetic ring clamp 122 includes a first abutting portion 1221 that abuts against the outer circumferential surface of the magnetic ring 20, and a pair of second abutting portions 1222 extending toward the center of the magnetic ring 20 and abutting against the axial ends of the magnetic ring 20. The first abutting portions 1221 of the pair of magnetic ring clamps (121, 122) fix the circumferential movement of the magnetic ring 20 from two oppositely arranged sides of the outer circumference of the magnetic ring 20. The four second abutting portions 1222 of the two magnetic ring clamps (121, 122) restrict the axial movement of the magnetic ring 20 and the rotation of the magnetic ring 20.

[0037] Furthermore, such as Figure 2 and Figure 4As shown, in the first magnetic ring clamping assembly 12 provided by this utility model, a pair of magnetic ring clamps (121, 122) abut against the axial end face of the magnetic ring 20 when clamping the magnetic ring 20. The width of the second abutting portion 1222 of the magnetic ring clamp 122 on the axial end face of the magnetic ring 20 is 0.3mm-20mm. The width of the second abutting portion 1222 of the magnetic ring clamp 122 on the axial end face of the magnetic ring 20 needs to be adaptively adjusted according to the different products processed by the winding machine 100 to improve the quality of the coil wound on the magnetic ring 20. The smaller the diameter of the magnetic ring, the smaller the width of the second abutting portion 1222 of the magnetic ring clamp 122 on the axial end face of the magnetic ring 20. When the width is less than 0.3mm, the stability of the magnetic ring clamp 122 decreases, and the second abutting portion 1222 cannot play the role of fixing and supporting the magnetic ring 20. The magnetic ring 20 may damage the magnetic ring clamp 122 or loosen from the second abutting portion 1222 of the magnetic ring clamp 122. When the size of the magnetic ring 20 is large enough, the width of the second abutment portion 1222 of the magnetic ring clamp 122 on its axis also increases accordingly. The width of the second abutment portion 1222 is determined according to the coil's structural design. Generally, when the diameter of the magnetic ring 20 is between 15mm and 60mm, the width of the second abutment portion 1222 of the magnetic ring clamp 122 on the axial direction of the magnetic ring 20 is 0.3mm to 20mm.

[0038] When the winding machine 100 is used to process single-winding differential-mode inductors, a single wire is wound around a magnetic ring 20 to form a complete and continuous coil. At this time, if the width of the second abutment portion 1222 is larger, the space where the wire cannot be completely wound in the area fixed by the magnetic ring clamps (121, 122) will be larger, resulting in gaps in the coil within the area fixed by the magnetic ring clamps (121, 122). Therefore, in order for the winding machine 100 to be suitable for processing single-winding differential-mode inductors, the area fixed by the magnetic ring clamps (121, 122) on the end face of the magnetic ring 20 should be minimized. This maintains the continuity, uniformity, and consistency of the wire winding, and also ensures the continuity of the coil on the magnetic ring 20, eliminating gaps. Therefore, the width of the second abutment portion 1222 on the axial end face of the magnetic ring 20 should be as small as possible.

[0039] When the winding machine 100 is used to process dual-winding differential-mode inductors or common-mode inductors, the first wire is wound from the starting end of the magnetic ring 20 and wound clockwise around half of the magnetic ring 20 to form the first coil. The second wire is wound from one side of the starting end of the magnetic ring 20 and wound counterclockwise around half of the magnetic ring 20 to form the second coil. The two coils are each wound with two separate wires, and the two wires are not connected at all, and the two coils are spatially separated. Sufficient gaps are needed on the magnetic ring 20 to distinguish the two sections of coil. Therefore, in order to make the winding machine 100 suitable for processing dual-winding differential-mode inductors, the uniform distribution of the two coils on the magnetic ring 20 is controlled as much as possible, and they are wound within the designed range. The width of the second abutment portion 1222 of the magnetic ring clamp 122 on the axial end face of the magnetic ring 20 is selected according to the design requirements of the dual-winding differential-mode inductor.

[0040] Furthermore, such as Figure 4 As shown, in this embodiment, the second abutment portion 1222 of the pair of magnetic ring clamps (121, 122) has different widths on the axial end face of the magnetic ring 20. A wire is wound around the magnetic ring 20 to form a continuous coil from the starting end to the ending end (the coil structure is not shown in the figure), as... Figure 4As shown, in this embodiment, the starting end of the coil is near the left side of the magnetic ring clamp 121, and the ending end of the coil is near the right side of the magnetic ring clamp 121. The coil starts winding around the magnetic ring from the left side of the magnetic ring clamp 121, passes through the magnetic ring clamp 122, and continues winding to the right side of the magnetic ring clamp 121. The magnetic ring clamp 122 is located in the middle section of the coil. In this embodiment, the width of the second abutting portion 1222 of the magnetic ring clamp 121 near the starting or ending end of the coil is L1, and the width of the second abutting portion 1222 of the magnetic ring clamp 122 located in the middle section of the coil is L2, satisfying the relationship: L1 > L2. In order to form a complete and continuous coil with uniform wire distribution in the middle on the magnetic ring 20, the width L2 of the magnetic ring clamp 122 located in the middle section of the coil should be controlled to reduce the problem of wire distribution difference caused by the setting of the magnetic ring clamp 122. To better suit single-winding differential-mode inductors, the magnetic ring clamping device 10 provided by this invention has a width L2 of the second abutment portion 1222 of the magnetic ring clamp 122 located in the middle section of the coil of the magnetic ring 20, which should be smaller than the width L1 of the second abutment portion 1222 of the magnetic ring clamp 121 located at the end of the coil. This allows the coil to be continuous on the magnetic ring 20 and reduces the gap between adjacent wires. In this case, the width L1 of the second abutment portion 1222 of the magnetic ring clamp 121 located at the beginning or end of the coil is 1mm-20mm. The width of the magnetic ring clamp 121 is determined by the coil structure design. When the coil design requires the beginning and end of the coil to be connected end-to-end, the smaller the width L1 of the magnetic ring clamp 121, the better, to ensure the requirements of the coil design. Furthermore, the width L1 of the magnetic ring clamp 121 is greater than the width L2 of the magnetic ring clamp 122. The slightly larger width L1 of the magnetic ring clamp 121 compared to the width L2 of the magnetic ring clamp 122 provides more support and restraint for the magnetic ring 20. Therefore, the width L1 of the magnetic ring clamp 121 has a relatively large range. If the width L1 is less than 1mm, it cannot be guaranteed that the magnetic ring clamp 121 can effectively support the magnetic ring 20 and ensure structural stability. Therefore, the width L1 of the magnetic ring clamp 121 should be greater than or equal to 1mm. When the coil design requires a certain width interval between the start and end ends of the coil, the width L1 of the magnetic ring clamp 121 is the design width. Generally, the width L1 of the magnetic ring clamp 121 is controlled between 1mm and 20mm. Figure 4 As shown, the width of the magnetic ring clamp 121 gradually decreases from the outer surface of the magnetic ring 20 to the center of the magnetic ring 20. Here, the width L1 of the magnetic ring clamp 121 is the maximum value of the width of the second abutment portion 1222 in the axial direction of the magnetic ring 20, as shown. Figure 4The width L2 of the second abutment portion 1222 of the magnetic ring clamp 122, located in the middle section of the coil, is 0.3mm-5mm. The width L2 of this magnetic ring clamp 122 affects the continuity and uniformity of coil winding; therefore, the smaller the width L2 of the magnetic ring clamp 122, the better, ensuring that the magnetic ring 20 will not loosen during winding, while maintaining clamping and structural stability. If the width of the magnetic ring clamp 122 is greater than 5mm, even when processing a magnetic ring 20 with a larger diameter (greater than 40mm), gaps may easily appear at the location where the magnetic ring clamp 122 is set during wire winding, which is detrimental to coil arrangement. Therefore, the width L2 of the magnetic ring clamp 122 should be controlled between 0.3mm and 5mm.

[0041] Furthermore, in the magnetic ring clamping device 10 provided by this utility model, the width of the second abutment portion of the pair of magnetic ring clamps on the first magnetic ring clamping assembly 12 is the same on the axial end face of the magnetic ring 20 (not shown in the figure). The width of the second abutment portion of the pair of magnetic ring clamps on the axial end face of the magnetic ring 20 is 0.3mm-10mm. The smaller the space occupied by the second abutment portion of the pair of magnetic ring clamps on the axial end face of the magnetic ring 20, the smaller the impact on the tightness of the coil. Moreover, the width of the second abutment portion of the magnetic ring clamp on the axial end face of the magnetic ring 20 is related to the diameter of the magnetic ring 20 itself. The larger the diameter of the magnetic ring 20, the larger the width of the second abutment portion of the magnetic ring clamp also becomes. If the width of the second abutment portion of the pair of magnetic ring clamps on the magnetic ring 20 is less than 0.3mm, the magnetic ring 20 cannot be effectively fixed, and the magnetic ring 20 is prone to loosening from the pair of magnetic ring clamps during the winding process. If the width of the second abutting part of a pair of magnetic ring clamps on the magnetic ring 20 is greater than 10mm, then the space occupied by the pair of magnetic ring clamps on the magnetic ring 20 is large (the axial end face occupies more than 20mm), which reduces the winding space of the coil and is not conducive to the arrangement of the coil.

[0042] Furthermore, such as Figure 1 As shown, the magnetic ring clamping device 10 provided by this utility model further includes a second magnetic ring clamping assembly 13 for clamping both axial ends of the magnetic ring 20, and a translation component 14 disposed on the mounting base 11 to drive the second magnetic ring clamping assembly 13 to move horizontally to the magnetic ring 20. The second magnetic ring clamping assembly 13 is fixed to the mounting base 11 by the translation component 14, and can move on the mounting base 11 toward the magnetic ring 20 clamped by the first magnetic ring clamping assembly 12 as driven by the translation component 14, and clamp the magnetic ring 20. The translation component 14 is existing technology and can be a motor guide rail, cylinder guide rail structure, etc., that is, to realize the reciprocating horizontal movement of the second magnetic ring clamping assembly 13 on the mounting base 11. When the second magnetic ring clamping assembly 13 is needed, the translation assembly 14 drives the second magnetic ring clamping assembly 13 to move toward the magnetic ring 20 and clamp the magnetic ring 20. When the second magnetic ring clamping assembly 13 is not needed, the translation assembly 14 drives the second magnetic ring clamping assembly 13 to move on the mounting base 11 to the side away from the magnetic ring 20.

[0043] Specifically, such as Figure 1 As shown, the second magnetic ring clamping assembly 13 includes a pair of clamping plates 131 and a second driving assembly 132 for driving the pair of clamping plates 131 to move towards each other or away from each other. The second driving assembly 132 is a conventional mechanism that can realize the relative movement of the pair of clamping plates 131 towards each other or away from each other. When the pair of clamping plates 131 move towards each other, they respectively abut against the two end faces of the magnetic ring 20 along the axial direction. In the magnetic ring clamping device 10 provided by this utility model, the pair of magnetic ring clamps (121, 122) of the first magnetic ring clamping assembly 12 move towards each other in the circumferential direction of the magnetic ring 20, clamping the magnetic ring 20 radially; the pair of clamping plates 131 of the second magnetic ring clamping assembly 13 move towards each other in the axial direction of the magnetic ring 20, clamping the magnetic ring 20 axially. The second magnetic ring clamping assembly 13 further secures the magnetic ring 20 during the winding process of the winding machine 100, preventing it from flipping or loosening relative to the pair of magnetic ring clamps (121, 122) due to wire disturbance. In particular, when the width of the second abutment portion of the pair of magnetic ring clamps (121, 122) is small, it can provide more support, ensuring the stability of the magnetic ring 20.

[0044] like Figure 4 As shown, when the pair of magnetic ring clamps 122 of the first magnetic ring clamping assembly 12 clamps the magnetic ring 20, the magnetic ring 20 is divided into a winding region 21 and a non-winding region 22. The pair of clamping pieces 131 of the second magnetic ring clamping assembly 13 clamps the non-winding region 22 of the magnetic ring 20. When the magnetic ring 20 is in the first half-wound formation, the pair of clamping pieces 131 of the second magnetic ring clamping assembly 13 clamps the two end faces of the magnetic ring 20 along its axial direction. When the magnetic ring 20 is flipped and in the second half-wound formation, the pair of clamping pieces 131 of the second magnetic ring clamping assembly 13 clamps the end faces of the coil that the magnetic ring 20 has just wound.

[0045] The magnetic ring clamping device 10 provided by this utility model has a first magnetic ring clamping assembly 12 that clamps and fixes the magnetic ring 20 from both sides of the circumference. A pair of magnetic ring clamps (121, 122) restrict the winding area to ensure that the unit wire is wound within the specified area, so as to ensure that the density and tightness of the coil meet the design requirements. The pair of magnetic ring clamps (121, 122) in the first magnetic ring clamping assembly 12 are located on both sides of the circumference of the magnetic ring 20, and the width of the second abutment portion 1222 of the magnetic ring clamp 122 is 0.3mm-10mm. By controlling the width of the second abutment portion 1222, it is suitable for different inductor processing. When winding a single coil inductor, the space occupied by the magnetic ring clamp 122 in the winding position of the magnetic ring 20 is minimized, and the influence of the magnetic ring clamp 122 on the wire winding is reduced, thereby ensuring the uniformity and consistency of the coil when winding on the magnetic ring 20, so as to improve the winding quality.

[0046] like Figure 7 and Figure 8 As shown, this is the winding machine 100 provided by this utility model. Figure 7 As shown, the winding machine 100 includes a mounting plate 30, a rotating platform 40 disposed on the mounting plate 30, and the aforementioned magnetic ring clamping device 10. The mounting base 11 of the magnetic ring clamping device 10 is fixed to the rotating platform 40 and rotates around the central axis of the magnetic ring 20. The rotating platform 40 is a conventional structure in the winding machine 100, disposed on both sides of the mounting plate 30. One side has a driving component and a rotating guide rail, and the other side has a fixing part. The mounting base 11 of the magnetic ring clamping device 10 is fixed to the fixing part of the rotating platform 40 and rotates relative to the mounting plate 30 as the driving component of the rotating platform 40 drives it. The rotation axis of the rotating platform 40 is the central line of the magnetic ring 20, thereby allowing the magnetic ring clamping device 10 to drive the clamped magnetic ring 20 to rotate around its axis under the drive of the rotating platform 40.

[0047] The winding machine 100 provided by this utility model adopts the aforementioned magnetic ring clamping device 10, which makes the winding machine 100 not only suitable for processing traditional common mode inductors and dual-winding differential mode inductors, but also able to more stably clamp and fix the magnetic ring 20. During the winding process of the winding machine 100, the magnetic ring 20 is clamped and driven to rotate, making it more suitable for single-winding differential mode inductors. By controlling the width of the magnetic ring clamp 122 on the axial end face of the magnetic ring 20, the influence of the magnetic ring clamp on the winding coil is reduced, thereby improving the winding quality of the single-winding differential mode inductor coil, avoiding gaps in the coil on the magnetic ring 20, and maintaining the continuity and uniformity of the coil.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
