Description

Technical Field

[0001] This application relates to the technical field of inductors, and in particular to a three-dimensional inductor with an asymmetric winding structure and a method for manufacturing the same. Background Technology

[0002] As electronic devices continue to evolve towards miniaturization and higher performance, inductors, as crucial electronic components, directly impact the operational efficiency and stability of the entire electronic system. With the rapid advancement of electronic technology, the performance requirements for inductors are becoming increasingly stringent. They not only need higher inductance but also the ability to withstand complex electromagnetic environments, reduce electromagnetic interference, and simultaneously meet miniaturization design requirements.

[0003] To improve the withstand voltage performance of traditional inductors, the methods generally include adding a physical isolation layer and wrapping with ordinary magnetic materials. However, this method can only reduce electromagnetic interference to a limited extent. There is still a large electromagnetic coupling phenomenon between adjacent windings, which reduces the withstand voltage performance of the inductor and reduces the performance and stability of the inductor. Summary of the Invention

[0004] To improve the performance and stability of inductors, this application provides a three-dimensional inductor with an asymmetric winding architecture and a method for manufacturing the same.

[0005] In a first aspect, this application provides a three-dimensional inductor with an asymmetric wire-wound architecture, employing the following technical solution:

[0006] A three-dimensional inductor with an asymmetric winding structure includes a carrier, two coils, and a magnetic conductor. The two coils are detachably mounted on the carrier and are wound in a spiral shape and staggered from each other. The magnetic conductor is mounted on the carrier and located between the two coils. The magnetic conductor is used to shield the magnetic field and can adjust the magnetic field strength as needed.

[0007] By adopting the above technical solution, two coils and a magnetic conductor are fixedly installed on the carrier. The two coils are located on both sides of the magnetic conductor and are staggered, i.e., the two coils are asymmetrical. In addition, the shielding effect of the magnetic conductor greatly reduces the risk of electromagnetic interference between the two coils and improves the performance and stability of the inductor. At the same time, the magnetic conductor can also adjust the strength of the magnetic field as needed, so that the magnetic field is more suitable for the operating environment of the inductor, further improving the performance and stability of the inductor.

[0008] Optionally, the magnetic conductive element includes:

[0009] Two fixing parts are set on the carrier;

[0010] Two magnetic conductive plates are mounted on two fixed parts;

[0011] Several magnetic conductive plates 2 are detachably mounted on two fixed parts and located between two magnetic conductive plates 1, and cooperate with the two magnetic conductive plates 1 to adjust the magnetic field strength.

[0012] By adopting the above technical solution, two fixing parts are used to fix and connect to the carrier, and two magnetic sheets correspond to two coils. As needed, magnetic sheets are installed on the two fixing parts and located between the two magnetic sheets. The two magnetic sheets work together to shield the magnetic field. Different degrees of shielding are achieved according to the different thicknesses of the magnetic structure between the two coils, so that the shielding effect can better meet the needs of the inductor operation. Moreover, no matter how many magnetic sheets there are, the distance between the two magnetic sheets and the two coils remains unchanged, which makes the inductor operation more stable.

[0013] Optionally, multiple insertion slots are provided on the opposite side walls of the two fixing parts and between the two magnetic sheets. The magnetic sheets are inserted into the insertion slots of the two fixing parts. Both fixing parts are provided with elastic members to prevent the magnetic sheets from detaching from the insertion slots.

[0014] By adopting the above technical solution, the number of magnetic conductive sheets 2 is designed according to the needs. Then, the magnetic conductive sheets 2 are squeezed into the elastic element and inserted into the insertion slot. Finally, the elastic element presses against the magnetic conductive sheets 2 for positioning, which improves the convenience of the adjustment process.

[0015] Optionally, it also includes two epoxy boards and two magnetic cores. The magnetic conductive component is disposed on the two epoxy boards and forms two mounting spaces with the epoxy boards and the carrier. Two insertion holes are provided on the carrier and located in the two mounting spaces at intervals. The two coils are located in the two mounting spaces and are positioned by being inserted into the two insertion holes through two pins. The two magnetic cores are disposed on opposite side walls of the magnetic conductive component and are positioned by passing through the two coils respectively.

[0016] By adopting the above technical solution, the epoxy board and the magnetic conductive component cooperate with the carrier to form two installation spaces. Then, the two coils are installed in the two installation spaces. During installation, the two pins of the coils are plugged into the two plug holes. Then, the two magnetic cores are installed on the magnetic conductive component and correspond to the two coils. During the installation process, the magnetic cores are positioned by passing through the coils. The formation of two installation spaces can further reduce the risk of electromagnetic interference between the two coils and improve the stability of the coils after installation, thereby further improving the performance and stability of the inductor.

[0017] Optionally, the magnetic core includes:

[0018] Two covers are mounted on the magnetic conductor and located outside the installation space;

[0019] The core is positioned on the two covers and passes through the coil.

[0020] By adopting the above technical solution, the core column is passed through the coil, and then the two covers are fixedly installed on the magnetic conductor and fixedly connected to both ends of the core column, thereby enabling the positioning of the coil and the installation of the magnetic core.

[0021] Optionally, the epoxy board is provided with two support assemblies that support the two coils respectively, and the support assemblies include:

[0022] Multiple support components are spaced along the coil axis on the magnetic sheet and are arc-shaped, and are used to support and position the coil between adjacent turns.

[0023] Support component two is slidably mounted on the epoxy board in a direction close to or away from support component one. The bottom of the coil is positioned by pressing against support component two under the action of gravity. After the pin is plugged into the plug hole, it can move to make way when support component two drives the coil to move.

[0024] Positioning element, used to position the support element at position two.

[0025] By adopting the above technical solution, the coil has a spiral structure and is fixed on the carrier by pins at both ends. As a result, the stability of the coil itself is poor, and the stability between the multiple turns formed by the coil winding is also poor, which reduces the performance and stability of the inductor during operation.

[0026] The positioning component unlocks the second support component, placing it away from the first magnetic sheet. The bottom of the coil is then positioned against the second support component. The coil is pushed so that its two pins are inserted into the two insertion holes for initial positioning. The coil and the second support component are then pushed closer to the first magnetic sheet and the first support component, allowing multiple first support components to be inserted between adjacent turns for support and positioning. Simultaneously, the pins are positioned against the insertion holes, and the positioning component positions the second support component. Therefore, the second support component supports the bottom of the coil, and multiple support components support the coil, thus jointly supporting the coil and improving its stability, as well as the performance and stability of the inductor.

[0027] At the same time, there is a certain elastic force between the bottom of the coil and the second support member. That is, the second support member and the positioning member can position the coil. Furthermore, the magnetic core passes through the coil for positioning, which can greatly improve the stability of the coil position and improve the performance and stability of the inductor.

[0028] The two magnetic components remain in their original positions, so adjusting the magnetic field will not affect the coil support, thus improving the inductor's performance and stability while adjusting the magnetic field. When the positioning component unlocks the second support component, the coil can be moved away from the first magnetic component, allowing it to be removed for replacement, further enhancing the convenience of inductor maintenance.

[0029] The coil is spiral-shaped, and the second support is inserted between two adjacent turns for support. That is, the second support is also spiral-shaped. Therefore, after the second support is inserted, it can also position the coil and prevent the pin from moving on the plug hole, thereby further improving the performance and stability of the inductor.

[0030] Optionally, the positioning element is an elastic arc-shaped strip that extends along the sliding direction of the second support member. The second support member has a placement groove for placing the arc-shaped strip and engaging with it. When the coil is installed, the coil is pushed to drive the second support member to squeeze the arc-shaped strip, and the arc-shaped strip moves out of the placement groove and presses against the second support member for positioning.

[0031] By adopting the above technical solution, the second support component moves and squeezes the arc-shaped strip, causing the arc-shaped strip to move out of the placement groove. The arc-shaped strip presses against the second support component for positioning, thereby positioning the second support component and the coil. When unlocking is required, the second support component moves back and squeezes the arc-shaped strip, causing the arc-shaped strip to move into the placement groove and engage with it, thus continuing to position the second support component. Therefore, it is convenient to remove the coil for replacement.

[0032] Optionally, the second support member has a support surface that fits against the coil, and the height of the side of the support surface closer to the magnetic sheet is lower than the height of the side farther from the magnetic sheet.

[0033] By adopting the above technical solution, the positioning component positions the second support component, thereby preventing the coil from moving away from the first magnetic sheet and the first support component. The pin abuts against the insertion hole, preventing the coil from continuing to approach the first magnetic sheet and the first support component. This greatly improves the positioning effect of the coil and enhances the performance and stability of the inductor.

[0034] Secondly, the inductor manufacturing method provided in this application adopts the following technical solution:

[0035] A method for manufacturing an inductor includes the following steps:

[0036] Skeleton design and manufacturing: Manufacture a winding skeleton with stepped winding grooves according to design requirements;

[0037] Winding process: The coil is produced on the bobbin using automated winding equipment;

[0038] Magnetic component installation: Install the required number of magnetic sheets into the insertion slots as needed, connect the two ends of the two fixing parts to the two epoxy boards, and connect the two epoxy boards to the carrier;

[0039] Install two coils: Connect the two pins of the coils to the two insertion holes respectively, so that one end of the coil is pressed against the second support for positioning. Then push the second support and the coil close to the first magnetic sheet at the same time, so that multiple first supports are inserted between two adjacent turns for support and positioning. The positioning component positions the second support and the coil.

[0040] Install the magnetic cores: Install the two magnetic cores onto the two fixed parts and position them by passing them through the two coils respectively.

[0041] By adopting the above technical solution, a winding frame with stepped winding grooves is manufactured according to design requirements. The coil is then produced on the frame using automated winding equipment. As needed, a magnetic sheet is inserted and installed into the insertion slot. The two ends of the magnetic sheet are connected to two epoxy boards, which are then connected to the carrier. The two leads of the coil are inserted and installed into the two insertion holes, so that one end of the coil is pressed against the second support for positioning. Then, the second support and the coil are pushed towards the first magnetic sheet simultaneously, allowing multiple first supports to be inserted between adjacent turns for support and positioning. Positioning components position the second support and the coil. Finally, two magnetic cores are installed on the magnetic sheet and pass through the two coils for positioning, thus improving the performance and stability of the inductor.

[0042] In summary, this application includes at least one of the following beneficial technical effects:

[0043] 1. By fixing two coils and a magnetic conductor to the carrier, the two coils are made asymmetrical. In addition, the shielding effect of the magnetic conductor greatly reduces the risk of electromagnetic interference between the two coils, thus improving the performance and stability of the inductor. At the same time, the magnetic conductor can also adjust the strength of the magnetic field as needed, so that the magnetic field is more suitable for the operating environment of the inductor, further improving the performance and stability of the inductor.

[0044] 2. Two mounting spaces are formed by the cooperation between the epoxy board and the magnetic conductive component and the carrier. Then, two coils are installed in the two mounting spaces, and two magnetic cores are installed on the magnetic conductive component and correspond to the two coils. During the installation process, the magnetic cores are positioned by passing through the coils. The formation of two mounting spaces can further reduce the risk of electromagnetic interference between the two coils and improve the stability of the coils after installation, thereby further improving the performance and stability of the inductor.

[0045] 3. Multiple support components are installed between adjacent turns for support and positioning. The pins are positioned against the insertion holes, and the positioning component positions the second support component. The second support component supports the bottom of the coil. Multiple support components support the coil together, thereby improving the stability of the coil itself and improving the performance and stability of the inductor. Attached Figure Description

[0053] The following provides a further detailed description of this application.

[0054] This application discloses a three-dimensional inductor with an asymmetric winding architecture.

[0055] Reference Figure 1 The three-dimensional inductor with an asymmetric winding structure includes a carrier 1, two coils 11, and a magnetic conductor 2. The carrier 1 is vertical, and the two coils 11 are detachably mounted on the carrier 1. The two coils 11 are wound in a spiral shape and are staggered, i.e., asymmetric, thereby reducing electromagnetic interference between the two coils 11. The magnetic conductor 2 is mounted on the carrier 1 and located between the two coils 11. The magnetic conductor 2 is used to shield the magnetic field and can adjust the strength of the magnetic field as needed.

[0056] Reference Figures 1-3 It also includes two epoxy boards 12 and two magnetic cores 3. The two epoxy boards 12 are fixedly installed on the side wall of the carrier 1 and are horizontal and vertically spaced apart. The magnetic conductor 2 is vertical and its two ends are fixedly connected to the two epoxy boards 12. The magnetic conductor 2, the epoxy boards 12 and the carrier 1 cooperate to form two installation spaces 15. Two insertion holes 13 are vertically spaced on the carrier 1 and located in the two installation spaces 15. The insertion holes 13 in the two installation spaces 15 are staggered. The two coils 11 are located in the two installation spaces 15 and are positioned by being inserted into the two insertion holes 13 through two pins 14. The staggered insertion holes 13 make the two coils 11 staggered. The two magnetic cores 3 are set on the opposite side walls of the magnetic conductor 2 and are positioned by passing through the two coils 11 respectively.

[0057] The magnetic conductive component 2 includes two fixing parts 21, two magnetic conductive sheets 22, and several magnetic conductive sheets 23. The two fixing parts 21 are arranged vertically opposite each other, and the fixing parts 21 extend vertically through the middle of the upper surface of the epoxy board 12 and then extend to the bottom of the epoxy board 12. The two magnetic conductive sheets 22 are integrally disposed on opposite ends of the two fixing parts 21, and the two magnetic conductive sheets 22 are correspondingly disposed with the two coils 11. The opposite side walls of the two magnetic conductive sheets 22 are flush with the opposite side walls of the two fixing parts 21.

[0058] Each of the two fixing parts 21 has a plurality of insertion slots 24 spaced apart at one end. The number of magnetic conductive sheets 23 is determined as needed. The magnetic conductive sheets 23 are inserted into the insertion slots 24 of the two fixing parts 21 for positioning. Elastic members 25 are fixedly installed on the side walls of the two fixing parts 21 and on both sides of the insertion slots 24. The elastic members 25 are horizontally arranged semi-cylindrical structures and are elastic. After the magnetic conductive sheets 23 press against the two elastic members 25, they are inserted into the insertion slots 24 until the magnetic conductive sheets 23 are positioned against the carrier 1, and the elastic members 25 press against the magnetic conductive sheets 23 for positioning, thereby preventing the magnetic conductive sheets 23 from detaching from the insertion slots 24. The number of magnetic conductive sheets 23 installed is determined according to the needs, thereby enabling the adjustment of the magnetic field strength of the two coils 11.

[0059] Two magnetic cores 3 are correspondingly arranged with two coils 11. Each epoxy board 12 has a through hole at the installation space 15. The magnetic core 3 includes two covers 31 and a core column 32. The two covers 31 are fixedly installed on the side walls of the two fixing parts 21 and are located on the upper and lower sides of the two epoxy boards 12. The two ends of the core column 32 are fixedly installed on the two covers 31. During installation, the core column 32 passes through the coil 11, thereby fixing the magnetic core 3 and positioning the coil 11.

[0060] Reference Figure 1 , Figures 4-6Two support components 4 are provided on the epoxy board 12 located at the lower position to support the two coils 11 respectively. The two support components 4 are respectively provided with two installation spaces 15. The support components 4 include multiple support members 41, support members 42 and positioning members 43. Multiple support members 41 are fixedly installed on the side wall of the magnetic sheet 22 near the coil 11 and are spaced apart along the axis of the coil 11. Multiple support members 41 are arc-shaped and the number is determined according to the number of turns of the coil 11, so that each support member 41 can be inserted between two adjacent turns of the coil 11 for support and positioning. The shape and size of the support member 41 match the size and shape of the space between two adjacent turns. The side of the support member 41 near the coil 11 is also arc-shaped and easy to insert between two adjacent turns. The support member 41 is spiral-shaped.

[0061] The second support member 42 is horizontally slidably mounted on the upper surface of the epoxy board 12, and the second support member 42 slides in the direction of approaching or moving away from the first magnetic sheet 22. At the same time, the sliding direction of the second support member 42 is perpendicular to the direction of the pin 14 being inserted into the plug hole 13. The second support member 42 has a clearance hole 44 for the core post 32 to pass through. A spiral support surface 45 is formed on the upper surface of the second support member 42 for tightly contacting the bottom of the coil 11.

[0062] Reference Figure 1 , Figures 4-6 Both the insertion hole 13 and the pin 14 are horizontal. After the pin 14 is inserted into the insertion hole 13, the pin 14 can move along the sliding direction of the support member 42 on the insertion hole 13, thereby making way when the support member 42 drives the coil 11 to move. The positioning member 43 is used to position the support member 42. The positioning member 43 is an elastic arc-shaped strip that extends along the sliding direction of the support member 42. The bottom of the support member 42 has a placement groove 46 that engages with the arc-shaped strip.

[0063] Reference Figures 3-6 The bottom of coil 11 is pressed against support 42 and the two pins 14 are inserted into the two insertion holes 13. The coil 11 is moved so that the bottom of coil 11 is in close contact with the support surface 45 for positioning. The coil 11 and support 42 are pushed closer to magnetic sheet 22 and support 41, so that multiple support 41 are inserted between adjacent turns for support and positioning. The pins 14 are positioned against the insertion holes 13, so that coil 11 and magnetic sheet 22 are kept at a certain distance. During the movement of support 42, positioning member 43 is moved out of placement groove 46 and positioned against the side wall of support 42 away from magnetic sheet 22 for positioning, thus completing the installation of coil 11.

[0064] The height of the support surface 45 near the magnetic sheet 22 is lower than the height of the side away from the magnetic sheet 22, preventing the coil 11 from moving away from the magnetic sheet 22. This allows the pin 14, the insertion hole 13, and the support surface 45 to cooperate in positioning the coil 11. When unlocking is required, the support member 42 and the coil 11 are pulled away from the magnetic sheet 22, causing the support member 42 to press against the positioning member 43. This causes the positioning member 43 to snap into place on the placement slot 46, thus disengaging the coil 11 from the multiple support members 41. The coil 11 can then be removed for replacement, improving the performance and stability of the inductor.

[0065] The working principle of this application embodiment is as follows:

[0066] The required number of magnetic conductive sheets 23 are inserted and installed on the insertion slots 24. The two fixing parts 21 are fixedly installed on the two epoxy boards 12. The two epoxy boards 12 are fixedly installed on the carrier 1. Then, the two coils 11 are installed in the two installation spaces 15. The bottom of the coils 11 is supported by the second support member 42, and multiple first support members 41 are inserted between adjacent turns to support and position the coils 11, so that the coils 11 in the two installation spaces 15 are in an asymmetrical state. At the same time, the magnetic field is adjusted by the magnetic conductive member 2, which greatly reduces the interference between the magnetic fields of the two coils 11 and improves the performance and stability of the inductor.

[0067] This application discloses a method for manufacturing an inductor.

[0072] Reference Figures 3-6 Install two coils 11: Insert the two pins 14 on the coil 11 into the two insertion holes 13 respectively, so that one end of the coil 11 presses against the support member 42 for positioning, and then push the support member 42 and the coil 11 close to the magnetic sheet 22 at the same time, so that multiple support members 41 are inserted between two adjacent turns for support and positioning, and the positioning member 43 positions the support member 42 and the coil 11.

[0073] Reference Figure 1 , Figure 3 Install the magnetic core 3: Install the two magnetic cores 3 onto the two fixing parts 21 and position them by passing them through the two coils 11 respectively.

[0074] The working principle of this application embodiment is as follows:

[0075] According to the design requirements, a winding frame with stepped winding grooves is manufactured. The coil 11 is produced on the frame using automated winding equipment. The required number of magnetic conductors 2 are inserted and installed into the insertion slots 24. The two ends of the two fixing parts 21 are connected to the two epoxy boards 12. The two epoxy boards 12 are connected to the carrier 1. The two pins 14 on the coil 11 are respectively inserted and installed into the two insertion holes 13, so that one end of the coil 11 is pressed against the support 42 for positioning. Then, the support 42 and the coil 11 are pushed simultaneously towards the magnetic sheet 22, so that multiple support 41 are inserted between adjacent turns for support and positioning. The positioning element 43 positions the support 42 and the coil 11, thereby achieving support and positioning of the coil 11. Finally, two magnetic cores 3 are installed on the two fixing parts 21 and respectively pass through the two coils 11 for positioning, improving the performance and stability of the inductor.

[0076] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
