[0020] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0021] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0022] In the description of this application, it should be noted that the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing 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, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the order of description of the following embodiments is not intended to limit the priority of the embodiments.

[0024] Please refer to Figures 1 to 4 The high-performance inductor device of this application includes a magnetic core 1, a terminal 2, and a winding 3.

[0025] In the specific implementation process, the magnetic core 1 includes a winding body 11 and a support body 12 disposed at both ends of the winding body 11. The terminals 2 are respectively connected to the side of the support body 12 away from the winding body 11. Each terminal 2 is provided with at least one winding body 4 and a patch electrode 5. The patch electrode 5 is arranged at a distance on the side of the winding body 4 and disposed on the end face of the support body 12. The winding 3 includes at least one coil wound on the winding body 11. The coil wire is wound once around the winding body 4 and then electrically connected to the winding body 4. The number of winding bodies 4 is set to M and the number of coils is set to N. Then the relationship between the number of winding bodies 4 and the number of coils is: M=N+1, where N≥1.

[0026] Therefore, based on the coil configuration of the winding body 4 and the winding 3 with M=N+1, the coil of the high-performance inductor only needs to be wound once to form the winding body 11 to form the winding 3, instead of making independent external lead connections for each turn. The winding 3 has only two lead ends on the winding body 4, which can reduce external welding / crimping points, reduce the risk of contact failure or cold welding cracks between the winding 3 and the terminal 2 due to vibration / impact, and thus improve the performance and reliability of the inductor.

[0027] Furthermore, based on this winding method that avoids the independent external leads of the coil, the wire diameter of the winding 3 coils can be reduced, and the wire spacing of the coils can be reduced. This increases the unit current density of the inductor under the same volume conditions, reduces the transmission loss of the inductor, and achieves the purpose of improving the performance of the inductor, that is, improving the overall performance of the inductor device.

[0028] In one example, the surface mount electrode 5 on each terminal 2 is located between adjacent wire wound bodies 4, or the wire wound body 4 on each terminal 2 is located between adjacent surface mount electrodes 5. This arrangement can flexibly select the positions of the wire wound body 4 and surface mount electrode 5 according to different external connection design requirements, so as to adapt to the matching requirements of the preset pads of the corresponding surface mount electrode 5 on the external device, and ensure the compatibility and process adaptability of the inductor during the mounting process.

[0029] It should be noted that the terminals 2 are respectively connected to the side of the support body 12 away from the winding body 11, and each terminal 2 is provided with at least one winding body 4. Here, the number of winding bodies 4 on the two support bodies 12 can be the same or different. Specifically: Figures 11a to 11f Can be regarded as Figure 1 or Figure 2 A diagram illustrating the wire wrapping method of the patch surface from a top-down perspective, see reference. Figure 11aThe winding body 11 has a winding body 4a and a winding body 4c on one end of the support body 12, and a winding body 4b on the other end of the support body 12. The winding 3 includes continuous coils 3a and 3b. The first end of the coil 3a is wound around the winding body 4a and then wound around the winding body 11 until the winding body 4b. The last end of the coil 3a is wound around the winding body 4b once, and then the last end of the coil 3a becomes the first end of the coil 3b. The winding body 4b continues to be wound around the winding body 11 until the winding body 4c. The winding of the winding 3 is completed by the last end of the coil 3b being wound around the winding body 4c once, so that the coils are electrically connected to the winding body after being wound around the winding body once. The number of winding bodies is 3, and the number of coils is 2, that is, M=N+1, where N≥1.

[0030] Of course, the beginning of the coil 3a can also be started by the winding body 4c, and after passing through the winding body 4b, the winding of the coil 3b can be completed by winding the winding body 4a once. This will not be elaborated here.

[0031] refer to Figure 11b ,and Figure 11a The difference is that the support body 12 at one end of the winding body 11 has a winding body 4a, and the support body 12 at the other end of the winding body 11 has a winding body 4b and a winding body 4c. Then, the first end of the coil 3a is wound around the winding body 11 until the winding body 4a. After the tail end of the coil 3a is wound around the winding body 4a once, the tail end of the coil 3a becomes the first end of the coil 3b. The winding body 4a continues to be wound around the winding body 11 until the winding body 4c. The winding of the winding 3 is completed by the tail end of the coil 3b being wound around the winding body 4c once. Of course, the first end of the coil 3a can also start from the winding body 4c. After the winding body 4a, the winding of the winding 3 is completed by the tail end of the coil 3b being wound around the winding body 4b once.

[0032] refer to Figure 11cThe winding body 11 has a winding body 4a and a winding body 4c on one end of the support body 12, and a winding body 4b and a winding body 4d on the other end of the support body 12. The winding 3 includes continuous coils 3a, 3b, and 3c. The beginning of coil 3a is wound with winding body 4a and then wound around the winding body 11 until winding body 4d. The end of coil 3a is wound once around winding body 4d, and then the end of coil 3a becomes the beginning of coil 3b. The winding body 4d continues to be wound on the winding body 11 until the winding body 4c, and the tail end of the coil 3b serves as the head end of the coil 3c. The winding body 4c continues to be wound on the winding body 11 until the winding body 4b. The winding of the winding 3 is completed by the tail end of the coil 3c being wound around the winding body 4b once. This achieves the purpose of the coil wires being wound around the winding body once and then electrically connected to the winding body. The number of winding bodies is 4, and the number of coils is 3, that is, M=N+1, where N≥1.

[0033] refer to Figure 11d The winding body 11 has a winding body 4a and a winding body 4c on one end of the support body 12, and a winding body 4b and a winding body 4d on the other end of the support body 12. The winding 3 includes continuous coils 3a, 3b, and 3c. The first end of coil 3a is wound with winding body 4a and then wound around the winding body 11 until it reaches winding body 4b. The last end of coil 3a is wound once around winding body 4b. The tail end of the coil 3b serves as the head end of the coil 3b, and is wound by the winding body 4b on the winding body 11 until the winding body 4c. The tail end of the coil 3b serves as the head end of the coil 3c, and is wound by the winding body 4c on the winding body 11 until the winding body 4d. The winding of the coil 3 is completed by the tail end of the coil 3c being wound by the winding body 4d once, thereby achieving the purpose of the coil wires being wound by the winding body once and then electrically connected to the winding body.

[0034] refer to Figure 11eThe support body 12 at one end of the winding body 11 has winding bodies 4a, 4c, and 4e, and the support body 12 at the other end of the winding body 11 has winding bodies 4b and 4d. The winding 3 includes continuous coils 3a, 3b, 3c, and 3d. The beginning of coil 3a is wound around winding body 4a and then wound around the winding body 11 until winding body 4b. The end of coil 3a is wound around winding body 4b once, and then the end of coil 3a becomes the beginning of coil 3b, which continues to be wound around the winding body 11 by winding body 4b until winding body 4b... The end of the winding body 4c and the end of the winding body 3b serve as the beginning of the winding body 3c. The winding body 4c continues to be wound on the winding body 11 until the winding body 4d. The end of the winding body 3c serves as the beginning of the winding body 3d. The winding body 4d continues to be wound on the winding body 11 until the winding body 4e. The winding of winding 3 is completed by the end of the winding body 3d being wound around the winding body 4e once. This achieves the purpose of the winding body of the coil being wound around the winding body once and then electrically connected to the winding body. The number of winding bodies is 5, and the number of coils is 4, that is, M=N+1, where N≥1.

[0035] refer to Figure 11f The support body 12 at one end of the winding body 11 has winding bodies 4a, 4c, and 4e, and the support body 12 at the other end of the winding body 11 has winding bodies 4b, 4d, and 4f. The winding 3 includes continuous coils 3a, 3b, 3c, 3d, and 3e. The beginning of coil 3a is wound around winding body 4a and then wound around the winding body 11 until winding body 4b. The end of coil 3a is wound around winding body 4b once, and then the end of coil 3a becomes the beginning of coil 3b, which continues to be wound around the winding body 11 until winding body 4c. The end of coil 3b also serves as... The beginning of the coil 3c is wound by the winding body 4c and continues to be wound on the winding body 11 until the winding body 4d. The end of the coil 3c is the beginning of the coil 3d and continues to be wound on the winding body 11 until the winding body 4e. The end of the coil 3d is the beginning of the coil 3e and continues to be wound on the winding body 11 until the winding body 4f. The winding of winding 3 is completed by the end of the coil 3e being wound on the winding body 4f once. This achieves the purpose of the coil wires being wound on the winding body once and then electrically connected to the winding body. The number of winding bodies is 6 and the number of coils is 5, that is, M=N+1, where N≥1.

[0036] In one example, continue combining Figure 7 and Figure 8 The winding body 4 is bent at an inclination angle from the outside to the inside of the terminal 2 in the opposite direction of the terminal 2. Through the design of this inclination structure, the winding body 4 can not only shrink inward in terms of spatial layout, but also reserve a suitable inward push position for subsequent solder joint arrangement.

[0037] Optional, tilt angle (e.g.) Figure 7 or Figure 8 The range of the marking Q is 5° to 85°, so that the winding body 4 can not only shrink inward in spatial layout, but also reserve a suitable inward push position for the subsequent solder joint arrangement, and buffer the tension of the winding lead.

[0038] Preferably, the tilt angle is 15°, 35°, 55° and 75°.

[0039] Continue to combine Figure 5 and Figure 6 The winding body 4 includes a bottom section 41, a recessed section 42 and a top section 43. The two ends of the recessed section 42 are respectively connected to the bottom section 41 and the top section 43 to form a winding groove 6. The end of the bottom section 41 away from the recessed section 42 is connected to the terminal 2, thereby facilitating the bending and tilting of the winding body 4.

[0040] The winding groove 6 is used for winding the coil wire and / or accommodating the electrical connection solder joint 6a between the winding body 4 and the coil 3a, ensuring the stability and consistency of the coil of winding 3 during the winding process and realizing the electrical connection between the winding body 4 and the coil wire of winding 3. Through the cooperation of the inclined structure and the winding groove, the solder joint 6a is completely retracted into the inside of the product after the electrical connection is completed, and will not protrude from the outer contour of the product. This prevents damage to the wire or solder joint caused by direct or indirect customer soldering board mounting or collision during use. The inward solder joint design releases the tension of the winding lead, reducing the possibility of wire loss when the inductor is subjected to impact and vibration, and improving the overall reliability of the product. At the same time, this design does not increase the external length of the product, and while maintaining miniaturization, it enhances the stability and durability of the internal connection, making it suitable for the packaging requirements of high-density electrical connections.

[0041] Optionally, the bottom section 41, the recessed section 42, and the top section 43 are integrally connected to ensure the overall structural strength of the winding body 4.

[0042] Preferably, the widths of the bottom section 41 and the recessed section 42 are L1 and L2, respectively, then: L1 > 1 times the thickness of the terminal 2; and L2 ≤ (L1 - 0.25 times the wire diameter of the winding 3).

[0043] The design of L1 > 1 times the thickness of terminal 2 ensures sufficient contact area between solder joint 6a and terminal 2, avoiding the problem of solder joint 6a falling off, and further ensuring the structural strength of the winding body 4. During the winding process of winding 3, it prevents the winding body 4 from tilting or deforming due to winding tension, thus ensuring the stability of product dimensions. In addition, L2 ≤ (L1 - 0.25 times the wire diameter of winding 3) can prevent the winding from loosening, which is conducive to the stable winding or hanging of the wire in the winding groove 6 of the winding body 4 during the winding process, avoiding the problem of wire slippage during the winding process, thereby improving the process stability and product consistency of winding 3.

[0044] The width of the top section 43 is L3, so L1=L3, in order to further ensure sufficient contact area between the solder joint 6a and the terminal 2 and avoid the problem of solder joint 6a falling off.

[0045] The recessed portion 42 may also be provided with auxiliary grooves 421 on one or both sides to further optimize the size of the winding groove 6, prevent the winding from coming loose, and ensure that the wire is stably wound or hung in the winding groove 6 of the winding body 4.

[0046] Optionally, the cross-sectional profile of the recess 42 is arc-shaped, crescent-shaped, rectangular, or wedge-shaped to facilitate the winding of the wire.

[0047] Continue to refer to Figure 3 and Figure 4 The support body 12 is provided with a clearance groove 7, which corresponds to the bend of the winding body 4 relative to the terminal 2. The bottom of the clearance groove 7 is not higher than the bend, and the winding body 4 is located in the clearance groove 7, that is, the winding body 4 can be completely contained in the clearance groove 7.

[0048] Therefore, the bent and inclined winding body 4 can avoid the solid area of ​​the support body 12, thus avoiding interference with the support body 12. At the same time, the winding body 4 is located in the clearance groove 7, which can provide a certain degree of protection during the winding process or when subjected to external impact, reducing the risk of deformation or displacement of the winding body 4, improving the mechanical stability of the inductor, and avoiding damage to the wire or solder joints caused by collisions during the use of the inductor.

[0049] Furthermore, the winding body 4 is provided with a bending groove 8 at the bend relative to the terminal 2, with the bending groove 8 facing the clearance groove 7. This facilitates the bending of the winding body 4 from the outside to the inside of the terminal 2 in the opposite direction. It also allows the bent part of the winding body 4 to be more fully accommodated and protected with the cooperation of the bending groove 8 and the clearance groove 7. The synergistic effect of the bending groove 8 and the clearance groove 7 can provide buffering when the device is subjected to external impact or vibration, thereby reducing the risk of deformation of the winding body 4 or damage to the solder joint 6a, and improving the mechanical reliability of the terminal 2 and the overall structure of the winding body 4.

[0050] In one example, the support body 12 has a receiving groove 9 on the side opposite to the winding body 11, and the terminal 2 is connected in the receiving groove 9 so that the support body 12 can form a stable connection with the terminal 2 through the receiving groove 9.

[0051] Preferably, the depth of the receiving groove 9 is ≥ 0.5 times the thickness of the terminal 2. Through the structural design of the receiving groove 9, the terminal 2 is made to be in an inward state in the overall structure of the product, avoiding the problem of traditional external terminals occupying extra length, thus not increasing the external length of the product. At the same time, the setting of the receiving groove 9 increases the magnetic conductive area between the magnetic core 1 and the cover plate, effectively improving the inductance while ensuring the overall structure of the magnetic core is compact.

[0052] Optionally, the support 12 is bonded and fixed to the terminal 2.

[0053] Continue to combine Figure 9 and Figure 10 The patch electrode 5 is bent from the side of the support body 12 and covers the end face of the support body 12 relative to the terminal 2. The patch electrode 5 and the end face of the support body 12 are provided with a minimum distance H, where H > 0 and H < 1 times the thickness of the terminal 2. This allows the patch electrode 5 to rebound and deform at H when subjected to external impact or vibration, thereby absorbing part of the impact energy and preventing the impact from directly acting on the body of the terminal 2 or the solder joint, thus improving the mechanical reliability and long-term stability of the terminal structure.

[0054] In one example, the high-performance inductor also includes a magnetic cover plate 10, which is connected to the end of the support 12 away from the patch electrode 5 and forms a closed magnetic circuit with the magnetic core 1, so that the magnetic flux is basically concentrated inside the magnetic core 1, reducing magnetic leakage loss and improving the inductor flux utilization and overall inductance.

[0055] Preferably, the magnetic cover plate 10 and the support body 12 can be fixed by means of bonding or pressing, so that the inductor can maintain structural stability under vibration, impact and high temperature environment.

[0056] Both the magnetic core 1 and the magnetic cover plate 10 are made of magnetic materials. These magnetic materials can include one or more of ferrite materials, magnetic metal alloy materials, iron-silicon alloy materials, or soft magnetic materials to meet the working requirements of the magnetic device.

[0057] In the specific implementation process, the winding body 11 can be designed as a rectangular structure so that the coils of the winding 3 can be stacked more easily, that is, more winding space is provided, and the edges and corners of the rectangular body can also be used to adjust the magnetic field distribution of the magnetic device, which helps to optimize the performance of the inductor and makes it easier to process and manufacture in the production process.

[0058] Furthermore, the coil wire of winding 3 can be made of copper enameled wire. It is understood that copper is an excellent conductive material with low resistance. Using copper enameled wire as winding 3 can reduce the resistance of the inductor and improve the current transmission efficiency. In addition, copper has good thermal conductivity, which can effectively conduct heat away from winding 3, avoiding the degradation or damage of inductor performance due to excessive temperature. On the other hand, copper enameled wire can usually withstand high temperatures and is suitable for applications in high-temperature environments. This is very important for magnetic devices that need to operate under high-temperature conditions. Moreover, copper enameled wire has high corrosion resistance and can resist the erosion of some chemicals, thereby extending the service life of magnetic devices.
