Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0040] The following combination Figures 1 to 10 The technical solutions disclosed in various embodiments of the present invention will be described in detail. It should be noted that, for ease of demonstration of the wiring of conductor 210, Figure 1 and Figure 2 The partition 190 is not shown.

[0041] This application discloses an inductor device that can be applied to various lighting products such as downlights, bulbs, lighting modules, ceiling lights, streetlights, and industrial lamps. In addition, this inductor device can also be applied to products in other electronic fields. Lighting products typically include a lamp body, a light source module, and a driver module. The light source module and the driver module are both mounted on the lamp body and electrically connected to each other. The light source module emits illumination light, and the driver module drives the light source module. The driver module includes a circuit board 300, and the inductor device can be mounted on the circuit board 300, but is not limited to being mounted on the circuit board 300. Specifically, the circuit board 300 can also be mounted on a mounting plane with pads, and can be a circuit board 300 in electronic devices, a housing, a support frame, etc. Figures 1 to 3 As shown, the inductor device may include an inductor frame 100 and a winding assembly 200. The winding assembly 200 is mounted on the inductor frame 100, and the inductor frame 100 can be fixedly attached to the circuit board 300.

[0042] The inductor frame 100 disclosed in this embodiment of the invention is used to mount the winding assembly 200. The inductor frame 100 and the winding assembly 200 disclosed in this embodiment of the invention can constitute an inductor device. Specifically, the inductor frame 100 is a basic structural component that can provide a mounting base for the winding assembly 200.

[0043] Reference Figures 1 to 6 The inductor frame 100 includes a support body 150 and a partition 190. The support body 150 is a basic structural component that can provide support for the winding assembly 200 and the partition 190, and provide a structural basis for opening the receiving slot 120.

[0044] The support body 150 has a receiving groove 120, which is used to install the winding assembly 200. The winding assembly 200 includes at least two sets of wires 210. A partition 190 is fixedly disposed at the bottom of the receiving groove 120. The partition 190 is located between two adjacent sets of wires 210 and separates the two adjacent sets of wires 210. The partition 190 and the support body 150 are integrally formed.

[0045] There are many ways to install the winding assembly 200 in the receiving groove 120. For example, the winding assembly 200 can also be fixed in the receiving groove 120 by means of adhesive, screws, welding, clips, etc. Therefore, this embodiment does not limit the specific way in which the winding assembly 200 is installed in the receiving groove 120. In an optional embodiment, the winding assembly 200 can be fixedly installed at the bottom of the receiving groove 120.

[0046] The partition 190 is located between two sets of adjacent wires 210, which can increase the spacing between the two sets of adjacent wires 210, avoid the distance between the two sets of adjacent wires 210 being too small, ensure the voltage withstand performance of the inductor, and ensure the quality of the inductor.

[0047] The partition 190 and the support body 150 can be integrally molded. Specifically, they can be injection molded into a single structure, thus eliminating the need for separate assembly of the partition 190 and the processes of fixing the partition 190 and the winding assembly 200. This simplifies the manufacturing process of the inductor frame 100, shortens its production cycle, and facilitates the assembly of the inductor frame 100 with the winding assembly 200, making the inductor device suitable for automated production. Alternatively, the support body 150 and the partition 190 can also be milled. Integrating the partition 190 and the support body 150 into a single structure also improves product consistency, ensures the stability of the partition 190's position, prevents loosening of the partition 190, and enhances the vibration resistance of the inductor device.

[0048] In one optional embodiment, the dimension of the partition 190 in the depth direction of the receiving groove 120 is greater than or equal to the dimension of the winding assembly 200 in the depth direction of the receiving groove 120, so that the partition 190 can completely block two sets of adjacent wires 210. Specifically, the dimension of the partition 190 in the depth direction of the receiving groove 120 can be equal to or less than the depth of the receiving groove 120, so as to prevent the partition 190 from protruding from the support body 150, so that the support body 150 can protect the partition 190 and prevent the partition 190 from colliding with external objects. Further, the dimension of the winding assembly 200 in the depth direction of the receiving groove 120 is smaller than the dimension of the receiving groove 120, so that the support body 150 can protect the winding assembly 200 and prevent the winding assembly 200 from colliding with or being snagged by external objects.

[0049] The partition 190 and the inner wall of the receiving groove 120 can be spaced apart, that is, there is a gap between the partition 190 and the inner wall of the receiving groove 120. The winding assembly 200 also includes a winding member 220, which is annular, and the wire 210 is wound around the winding member 220. The partition 190 passes through the corresponding central hole of the winding member 220.

[0050] Furthermore, in the length or width direction of the partition 190, a gap is formed between the partition 190 and the inner wall of the corresponding central hole of the winding member 220. That is, the radial dimension of the partition 190 in the winding member 220 is smaller than the diameter of the corresponding central hole of the winding member 220, thereby facilitating the assembly of the winding member 220 into the receiving groove 120. Furthermore, the width of the gap is smaller than the diameter of the wire 210 to prevent the wire 210 from crossing the partition 190 along the gap between the partition 190 and the inner wall of the corresponding central hole of the winding member 220, ensuring that the partition 190 can effectively block two sets of adjacent wires 210 and improve the withstand voltage performance of the inductor. Of course, in the length or width direction of the partition 190, both sides of the partition 190 can also abut against and connect to the inner wall of the corresponding central hole of the winding member 220.

[0051] Optionally, the center hole of the winding member 220 is provided with a positioning groove, the width of which is adapted to the thickness of the partition 190, so that both sides of the partition 190 in the length or width direction can be embedded in the positioning groove. The dimension of the partition 190 in the length direction is greater than or equal to the dimension in the width direction. The dimension of the partition 190 in the width direction is greater than the dimension in the thickness direction.

[0052] Reference Figures 1 to 5The inductor frame 100 may further include a mounting surface 110, a first connecting post 160, and a second connecting post 170. The support body 150 is the basic structural component, providing a mounting base for the first connecting post 160 and the second connecting post 170. The mounting surface 110 is the side of the support body 150 closest to the circuit board 300. Specifically, when the inductor is mounted on the circuit board 300, the mounting surface 110 of the support body 150 is close to the circuit board 300. Optionally, the mounting surface 110 can be mounted flush against the circuit board 300. Of course, a gap may also be provided between the mounting surface 110 and the circuit board 300.

[0053] Optionally, the first connecting post 160 and the second connecting post 170 are circumferentially disposed on the bracket body 150, and both the first connecting post 160 and the second connecting post 170 are provided with a welding surface 161. The welding surface 161 may be located on the side of the first connecting post 160 and the second connecting post 170 near the mating mounting surface 110. Both ends of the wire 210 extend out of the receiving groove 120. The first end of the wire 210 is wound around the first connecting post 160, and the first end of the wire 210 at least partially covers the welding surface 161 corresponding to the first connecting post 160. The second end of the wire 210 is wound around the second connecting post 170, and the second end of the wire 210 at least partially covers the welding surface 161 corresponding to the second connecting post 170.

[0054] It should be noted that the conductor 210 includes two ends, namely a first end and a second end. The first end of the conductor 210 mentioned in this application refers to the portion of the conductor 210 that is close to the first end and is not wrapped around the winding member 220; the second end of the conductor 210 mentioned in this application refers to the portion of the conductor 210 that is close to the second end and is not wrapped around the winding member 220.

[0055] Optionally, the first connecting post 160 and the second connecting post 170 are formed by extending from the side wall of the support body 150 in a direction away from the receiving groove 120. The extending direction of the first connecting post 160 and the second connecting post 170 is perpendicular to the depth direction of the receiving groove 120, that is, the first connecting post 160 and the second connecting post 170 are arranged circumferentially on the side of the support body 150. The first connecting post 160 and the second connecting post 170 are respectively used to wind the two ends of the wire 210, and the wire 210 wound on the first connecting post 160 and the second connecting post 170 can at least partially cover the welding surface 161 corresponding to the second connecting post 170 to facilitate welding. Specifically, during the process of assembling the inductor device onto the circuit board 300, the wire 210 wound on the first connecting post 160 and / or the second connecting post 170 is at least partially melted by high temperature, so that the molten metal can flow onto the pads on the circuit board 300, and the molten metal can be welded to the pads on the circuit board 300 by cooling. Because this structure eliminates the need for pre-reserved areas on the solder pads for pins to pass through during soldering, the area of ​​the solder pads can be significantly reduced. Furthermore, the soldering part can be completely hidden between the inductor and the circuit board 300, thereby greatly saving the area of ​​the circuit board 300.

[0056] To improve assembly stability, the first connecting post 160 and the second connecting post 170 can be symmetrically arranged on both sides of the bracket body 150, and both the first connecting post 160 and the second connecting post 170 can be wound with wire 210 and soldered to the circuit board 300. It should be noted that if the number of wire ends in the winding assembly 200 is less than the number of the first connecting post 160 and the second connecting post 170, auxiliary wires can be independently wound around some of the first connecting posts 160 and / or the second connecting post 170 so that some of the first connecting posts 160 and / or the second connecting post 170 can be soldered to the circuit board 300 through the auxiliary wires. Of course, if the wires 210 in the winding assembly 200 do not need to be connected to the circuitry in the circuit board 300, both the first connecting post 160 and the second connecting post 170 can be soldered to the circuit board 300 by winding with auxiliary wires. It should be noted that auxiliary wires refer to wires used only for winding around the first connecting post 160 and / or the second connecting post 170 for soldering. It should be emphasized that auxiliary wires can be used only for soldering and not connected to the circuitry of electronic devices. The electronic device described in this application may be an electronic device with an inductor.

[0057] In the above embodiment, both sides of the support body 150 can be welded and fixed to the circuit board 300, thereby improving the stability of the connection between the inductor frame 100 and the circuit board 300. Furthermore, the number of the first connecting posts 160 and the second connecting posts 170 welded to the circuit board 300 can be between one and three. Preferably, the total number of the first connecting posts 160 and the second connecting posts 170 can be four, and the first connecting posts 160 and the second connecting posts 170 welded to the circuit board 300 are symmetrically distributed on both sides of the support body 150.

[0058] In one optional embodiment, the soldering surface 161 and the mounting surface 110 satisfy the condition that the conductor 210 covering the soldering surface 161 is flush with or extends beyond the mounting surface 110. Optionally, the soldering surface 161 may extend beyond the mounting surface 110, that is, the first connecting post 160 and the second connecting post 170 at least partially protrude from the mounting surface 110, to ensure that the conductor 210 wound on the first connecting post 160 and the second connecting post 170 can make sufficient contact with the pads on the circuit board 300, so that the conductor 210 on the first connecting post 160 and the second connecting post 170 can be soldered to the pads in the circuit board 300, thereby improving the stability of the electrical connection between the inductor and the circuit board 300. Of course, the soldering surface 161 may also be flush with the mounting surface 110, thereby allowing the conductor 210 wound on the first connecting post 160 and the second connecting post 170 to protrude from the mounting surface 110. In another alternative embodiment, the welding surface 161 may also be recessed into the mounting surface 110, and the wire 210 may be flush with or extend beyond the mounting surface 110 by wrapping the wire 210.

[0059] Reference Figures 1 to 4 The inductor frame 100 also includes a first clearance groove 130 and a second clearance groove 140. Both the first clearance groove 130 and the second clearance groove 140 penetrate the groove wall of the receiving groove 120. The two ends of the wire 210 pass through the first clearance groove 130 and the second clearance groove 140 respectively and exit the receiving groove 120.

[0060] Specifically, the inductor frame 100 provides a structural basis for the opening of the first clearance groove 130 and the second clearance groove 140. In this embodiment, by opening the first clearance groove 130 and the second clearance groove 140 on the inductor frame 100, not only can the processing difficulty of the inductor frame 100 be reduced, but the installation of the winding assembly 200 can also be facilitated, thereby reducing the manufacturing difficulty of the inductor device and making it suitable for automated production. Specifically, the first clearance groove 130 and the second clearance groove 140 can be machined by a milling machine, or they can be cast during the casting process of the support body 150.

[0061] Of course, holes can also be drilled in the bracket body 150 so that the two ends of the wire 210 can pass through the receiving slot 120. However, directly slotting in the bracket body 150 can further simplify the manufacturing of the inductor frame 100 and is suitable for automated production.

[0062] Reference Figure 3 and Figure 4 The first clearance groove 130 includes a first groove bottom 131, and the second clearance groove 140 includes a second groove bottom 141. The winding assembly 200 also includes a winding member 220, around which a wire 210 is wound. The first end of the wire 210 is located on the side of the winding member 220 away from the opening of the receiving groove 120, and the second end of the wire 210 is located on the side of the winding member 220 close to the opening of the receiving groove 120. The first end of the wire 210 exits the receiving groove 120 through the first clearance groove 130. The second end of the wire 210 exits the receiving groove 120 through the second clearance groove 140. This provides a channel for the wire 210 to exit the receiving groove 120, simplifies the structure of the inductor frame 100, facilitates the manufacturing of the inductor frame 100, and reduces the assembly difficulty between the inductor frame 100 and the winding assembly 200.

[0063] Reference Figure 10 The distance between the bottom of the first slot 131 and the opening of the receiving slot 120 is the fifth distance 105. The distance between the side of the winding assembly 200 away from the opening of the receiving slot 120 and the opening of the receiving slot 120 is the sixth distance 106. The fifth distance 105 is greater than or equal to the sixth distance 106. The distance between the bottom of the second slot 141 and the opening of the receiving slot 120 is the seventh distance 107. The distance between the side of the winding component 220 near the opening of the receiving slot 120 and the opening of the receiving slot 120 is the eighth distance 108. The seventh distance 107 is greater than or equal to the eighth distance 108. This technical solution not only avoids the wire 210 pulling the winding component 220 towards the slot opening of the receiving groove 120, but also uses the first end of the wire 210 to fix the winding component 220, so that the winding assembly 200 can be fixed on the side of the receiving groove 120 away from the slot opening of the receiving groove 120. This eliminates the need to fix the winding assembly 200 in the receiving groove 120 by means of glue, screws, or welding, simplifying the assembly process of the winding assembly 200 and the inductor frame 100 and shortening the production cycle of the inductor device.

[0064] It should be noted that the distance between a certain part of the inductor frame 100 and the opening of the receiving groove 120 in this application refers to the distance between the plane where the part and the opening of the receiving groove 120 are located. Optionally, the receiving groove 120, the first groove bottom 131, and the second clearance groove 140 are formed on the same side of the support body 150 to facilitate the processing of the receiving groove 120, the first groove bottom 131, and the second clearance groove 140. Further optionally, the receiving groove 120, the first groove bottom 131, and the second clearance groove 140 are formed on the same plane.

[0065] There are many ways to allow the first and second ends of the wire 210 to pass through the receiving groove 120. Specifically, a through hole can be made in the groove wall of the receiving groove 120 so that the first and second ends of the wire 210 can pass through the through hole in the groove wall of the receiving groove 120. Alternatively, grooves can be made again in the bottom of the first relief groove 130 and the second relief groove 140 so that the first and second ends of the wire 210 can pass through the grooves in the bottom of the first relief groove 130 and the second relief groove 140, respectively, and exit the receiving groove 120. Therefore, the first and second ends of the wire 210 described in this application can pass through the receiving groove 120 from, but are not limited to, the first relief groove 130 and the second relief groove 140.

[0066] Reference Figure 4 , Figure 5 and Figure 7 The inductor frame 100 may further include a positioning post 180, which is fixedly mounted on the support body 150. The distance between the side of the positioning post 180 away from the opening of the receiving groove 120 and the opening of the receiving groove 120 is a first distance 101. The distance between the side of the winding member 220 away from the opening of the receiving groove 120 and the opening of the receiving groove 120 is a second distance 102. The first distance 101 is greater than or equal to the second distance 102. The first end of the wire 210 passes through the receiving groove 120 from the first clearance groove 130, and the wire 210 passes around the positioning post 180 away from the opening of the receiving groove 120 and is wound around the first connecting post 160. Optionally, the positioning post 180 and the first connecting post 160 may, but are not limited to, be located on the same side of the support body 150. In one embodiment, the positioning post 180 and the first connecting post 160 are disposed on the same side of the bracket body 150 to reduce the distance between the positioning post 180 and the first connecting post 160, reduce the length of the wire 210, and reduce the cost of manufacturing the inductor.

[0067] In the above embodiment, the positioning post 180 can provide support for the wire 210, thereby enabling the wire 210 to generate a pulling force on the winding component 220 towards the side away from the opening of the receiving groove 120. This allows the wire 210 to be fixed to the bottom of the receiving groove 120. Bypassing the positioning post 180, the wire 210 not only receives support from the positioning post 180 but also reduces the assembly difficulty between the inductor frame 100 and the winding assembly 200.

[0068] In one optional embodiment, a positioning groove is provided on the side of the positioning post 180 away from the opening of the receiving groove 120, and the wire 210 is at least partially recessed in the positioning groove to prevent the wire 210 from slipping off the positioning post 180. Optionally, the distance between the bottom of the positioning groove and the opening of the receiving groove 120 is greater than the distance between the side of the winding member 220 away from the mating mounting surface 110 and the mating mounting surface 110.

[0069] Reference Figure 2 , Figure 3 and Figure 8 The distance between the side of the second connecting post 170 away from the opening of the receiving groove 120 and the opening of the receiving groove 120 is the third distance 103, and the distance between the side of the winding assembly 200 near the opening of the receiving groove 120 and the opening of the receiving groove 120 is the fourth distance 104. The third distance 103 is greater than or equal to the fourth distance 104. After the second end of the wire 210 passes through the receiving groove 120, it winds from the side of the second connecting post 170 away from the opening of the receiving groove 120 toward the side of the second connecting post 170 closer to the opening of the receiving groove 120, so that the second connecting post 170 can provide support for the second end of the wire 210, thereby allowing the second end of the wire 210 to provide a force to the winding assembly 220 toward the side away from the opening of the receiving groove 120, thus ensuring that the winding assembly 200 can be fixed at the bottom of the receiving groove 120, preventing the winding assembly 200 from moving toward the circuit board 300, ensuring the gap between the winding assembly 200 and the circuit board 300, which is beneficial for heat dissipation of the inductor.

[0070] Reference Figure 2 , Figure 4 and Figure 5Both the first connecting post 160 and the second connecting post 170 can be provided with an anti-detachment part 162. The anti-detachment part 162 is located at the end of the first connecting post 160 and the second connecting post 170 away from the support body 150, and protrudes from the first connecting post 160 and the second connecting post 170, and is in contact with the surface of the wire 210. In this embodiment, the anti-detachment part 162 can be provided on any surface of the first connecting post 160 and the second connecting post 170, since the wire 210 wound on the first connecting post 160 or the second connecting post 170 is a whole. Therefore, it is sufficient to prevent any part of the wire 210 wound on the first connecting post 160 or the second connecting post 170 from detaching from the first connecting post 160 or the second connecting post 170. However, in order to ensure the soldering effect, it is preferable to keep the soldering surface 161 as close as possible to the circuit board 300 when assembling the inductor device. Therefore, in this embodiment, the anti-detachment part 162 is preferably provided on other surfaces of the first connecting post 160 and the second connecting post 170 other than the soldering surface 161. Furthermore, when the two first connecting posts 160 are parallel, the anti-detachment part 162 can be provided on the opposite sidewalls of the two first connecting posts 160. When the two second connecting posts 170 are parallel, the anti-detachment part 162 can be provided on the opposite sidewalls of the two second connecting posts 170.

[0071] Reference Figure 4 The system comprises at least two first connecting posts 160 and two second connecting posts 170. The first connecting posts 160 are arranged parallel to each other on the first side of the support body 150, and the second connecting posts 170 are arranged parallel to each other on the second side of the support body 150, with the first and second sides facing away from each other. The parallel arrangement of the two first connecting posts 160 allows them to be simultaneously welded to the circuit board 300, eliminating the need to rotate the inductor frame 100 or adjust the position of the workpiece during welding. This simplifies the welding process, meets the requirements of automated production processes, and improves the welding quality between the inductor frame 100 and the circuit board 300.

[0072] Reference Figures 1 to 6 Optionally, the mounting surface 110 can be flat to facilitate the installation of the inductor frame 100.

[0073] Optionally, the receiving groove 120, the first clearance groove 130 and the second clearance groove 140 are formed on the mating mounting surface 110 so that after the inductor is mounted on the circuit board 300, it can at least partially cover the receiving groove 120, the first clearance groove 130 and / or the second clearance groove 140 to prevent foreign objects from entering the receiving groove 120, so that the bracket body 150 can better protect the winding assembly 200.

[0074] In one optional embodiment, the depth of the receiving groove 120 is greater than the dimension of the winding assembly 200 in the depth direction of the receiving groove 120. Therefore, when the winding assembly 200 is installed in the receiving groove 120, the winding assembly 200 is recessed into the mating mounting surface 110, and the distance between the winding assembly 200 and the mating mounting surface 110 is greater than zero. Furthermore, when the inductor frame 100 is mated and mounted on the circuit board 300, the winding assembly 200, the first clearance groove 130, and the second clearance groove 140 form a through-path 400 with the circuit board 300. This allows wiring to be routed below the inductor frame 100 and the winding assembly 200, i.e., between the inductor and the circuit board 300, reducing the area occupied by the inductor on the circuit board 300 and increasing the wiring area of ​​the circuit board 300.

[0075] Furthermore, the depths of the receiving groove 120, the first clearance groove 130, and the second clearance groove 140 can be adjusted as needed to regulate the dimensions of the wiring channel 400 in the depth direction of the receiving groove 120, thus accommodating the wiring of the circuit board 300. Specifically, the deeper the receiving groove 120, the first clearance groove 130, and the second clearance groove 140 are recessed into the mounting surface 110, the larger the dimensions of the wiring channel 400 in the depth direction of the receiving groove 120. This allows for the placement of space-consuming electronic components or circuits between the inductor and the circuit board 300. Of course, if it is not necessary to place space-consuming electronic components or circuits between the inductor and the circuit board 300, the depth of the receiving groove 120, the first clearance groove 130, and the second clearance groove 140 recessed into the mounting surface 110 can be reduced to decrease the space occupied by the inductor in the electronic device.

[0076] Additionally, it should be noted that the depth of the receiving groove 120 mentioned in this application refers to the distance between the bottom of the receiving groove 120 and the mating mounting surface 110; the depth of the first clearance groove 130 refers to the distance between the bottom of the first clearance groove 130 and the mating mounting surface 110; and the depth of the second clearance groove 140 refers to the distance between the bottom of the second clearance groove 140 and the mating mounting surface 110. The depth direction of the receiving groove 120 refers to the direction perpendicular to the mating mounting surface 110.

[0077] Reference Figures 1 to 3The first clearance groove 130 and the second clearance groove 140 can be disposed on opposite sides of the receiving groove 120, so that the winding assembly 200, the first clearance groove 130 and the second clearance groove 140 and the circuit board 300 form a straight-line routing channel 400, which facilitates wiring between the inductor and the circuit board 300. Furthermore, the number of the first clearance groove 130 and the second clearance groove 140 can be at least two, so that after the inductor frame 100 is mounted on the circuit board 300, at least two intersecting routing channels 400 can be formed, further facilitating wiring between the inductor frame 100 and the circuit board 300 and increasing the diversity of wiring paths between the inductor frame 100 and the circuit board 300.

[0078] In the above embodiments, the first clearance groove 130, the second clearance groove 140, and the receiving groove 120 form a wiring channel 400 penetrating the inductor frame 100 between the circuit board 300 and the first clearance groove 130 and the second clearance groove 140. This allows the first clearance groove 130 and the second clearance groove 140 to not only provide a channel for the wire 210 to pass through the receiving groove 120, but also to form the wiring channel 400. This achieves multiple uses for the first clearance groove 130 and the second clearance groove 140, simplifies the structure of the inductor frame 100, and facilitates the manufacturing of the inductor frame 100. Furthermore, it can reduce the assembly difficulty between the inductor frame 100 and the winding assembly 200.

[0079] Optionally, the inductor frame 100 described in this application can be applied to common mode inductor devices.

[0080] Based on the inductor frame 100 provided by the present invention, this application also provides an inductor device. Specifically, the inductor device disclosed in the embodiments of this application includes a winding assembly 200 and the inductor frame 100 described in any of the above embodiments. Specifically, the winding assembly 200 is fixedly installed in the receiving groove 120 so that the inductor frame 100 can provide support for the winding assembly 200, so that a wiring channel 400 can be formed between the inductor device and the circuit board 300. This allows wiring to be performed between the inductor device and the circuit board 300, thereby increasing the wiring area of ​​the circuit board 300.

[0081] Reference Figure 1 , Figure 2 and Figure 9 The winding assembly 200 includes a conductor 210 and a winding member 220. The conductor 210 is wound around the winding member 220, with a first end of the conductor 210 located on the side of the winding member 220 away from the opening of the receiving groove 120; and a second end of the conductor 210 located on the side of the winding member 220 closer to the opening of the receiving groove 120. The first end of the conductor 210 extends out of the receiving groove 120 through a first clearance groove 130. The second end of the conductor 210 extends out of the receiving groove 120 through a second clearance groove 140, so that the conductor 210 in the winding assembly 200 can be electrically connected to other electronic components or parts.

[0082] Reference Figure 1 , Figure 2 and Figure 9 The winding component 220 can be a ring, and there are two wires 210. The wires 210 are symmetrically wound around the winding component 220, and the two wires 210 cover two different arc segments in the winding component 220. Specifically, the arc segments covered by the two wires 210 do not overlap. The winding component 220 is a ring-shaped magnetic component, such as a magnetic ring. The wires 210 pass through the corresponding center hole of the winding component 220 and are wound around it. Specifically, the length of the arc segment covered by the wires 210 can be adjusted by controlling the diameter of the wires 210 and the number of turns.

[0083] Reference Figure 3 The partition 190 can pass through the central hole of the winding member 220. Optionally, the width of the partition 190 in the radial direction of the winding member 220 can be equal to the inner diameter of the winding member 220, that is, the diameter of the central hole of the winding member 220 is equal to the width of the partition 190 in the radial direction of the winding member 220. This allows the partition 190 to divide the central hole of the winding member 220 into two through holes, allowing two wires 210 to pass through the through holes on both sides of the partition 190 and be wound around the winding member 220, ensuring that the two wires 210 can be separated by the partition 190. It should be noted that the thickness of the partition 190 is less than the width and length of the partition 190, and the thickness of the partition 190 is less than the diameter of the central hole of the winding member 220, thereby ensuring that through holes for passing wires 210 can be formed on both sides of the partition 190 in the thickness direction. Optionally, the inductor device described herein can be a common-mode inductor device.

[0084] In addition to the above, the inductor provided in this embodiment is typically used in electrical equipment such as lamps. For example, when used in a lamp, the lamp typically includes a lamp body, a light source module, and a driver module. The lamp body typically includes a housing and a cover. The light source module and the driver module are both mounted on the lamp body and are electrically connected to each other. The light source module typically includes only a light source board and LED chips mounted on the light source board, while the driver module includes a driver board and a series of components mounted on the driver board, among which the inductor is one.

[0085] Due to the limited space within the lamp fixture and the compact arrangement of components, and because the inductor is a magnetic element, it may interfere with the normal operation of other components. Therefore, to avoid interference with other components, the inductor frame 100 in this embodiment can be made of magnetically shielded materials such as magnetic glue or magnetic ferrite. Since the winding assembly 200 is installed within the receiving groove 120, the winding assembly 200 can be surrounded by the inductor frame 100. Because the inductor frame 100 is made of magnetically shielded material, it can shield the magnetic field generated by the winding assembly 200, preventing the magnetic field from interfering with other electronic components in the lamp fixture.

[0086] In some lighting fixtures, the light source board and driver board may be integrated, in which case some of the light emitted by the LED chip may shine onto the inductor. Typically, the magnetic materials used in inductors are dark-colored or even black, with high light absorption and extremely low reflectivity, leading to some wasted light energy. In this embodiment, the surface of the inductor frame 100 can be specifically coated with a light-colored (e.g., white) reflective material to give it higher light reflectivity.

[0087] The above embodiments of the present invention focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0088] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
