[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art belonging to the technical field of the present application. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application. The terms "first", "second", "third", "fourth", etc. (if present) in the specification of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order.

[0031] In addition, the described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the present disclosure.

[0032] Reference Figures 1 to 5 As shown, the flat inductor proposed in the embodiment of the present application includes:

[0033] A magnetic core 100, wherein the middle portion of the magnetic core 100 is hollow and the magnetic core 100 is vertically arranged; the magnetic core 100 is divided into a winding area 110 and a fixing area 120;

[0034] A flat coil 200, the flat coil 200 is wound around the magnetic core 100 in the winding area 110, and two terminals 210 of the flat coil 200 are respectively located on two sides of the magnetic core 100 in the fixing area 120;

[0035] The base 300 includes a support member 310, a first limiting boss 320, and arc grooves 330 at both ends of the first limiting boss 320. The first limiting boss 320 abuts against the magnetic core 100 of the fixed area 120. The two arc grooves 330 are arranged corresponding to the flat coil 200 close to the fixed area 120. The support member 310 is used to fix the magnetic core 100 of the fixed area 120.

[0036] Therefore, by providing the arc groove 330, the probability of the coils on both sides of the fixing area 120 being squeezed can be reduced while the coils can be fixed. At the same time, by providing the support 310, the magnetic core 100 can be fixed, thereby reducing the probability of the magnetic core 100 being skewed. When assembling the flat inductor, only the position of the flat coil 200 and the installation method of the base 300 need to be considered, and the assembly is simpler. Therefore, compared with the related art, the flat inductor of the embodiment of the present application can reduce the difficulty of assembling the flat inductor.

[0037] It should be noted that the outer contour shape of the magnetic core 100 can be selectively set according to actual needs, such as square, round, etc. Figure 1 As shown, the outer contour of the magnetic core 100 is circular, and the hollow part is circular, so as to form a ring shape, and the flat coil 200 is wound on the ring-shaped magnetic core 100 .

[0038] It should be noted that the vertical setting means setting perpendicular to the base 300 .

[0039] It should be noted that by reserving the fixing area 120 in the magnetic core 100 only for fixing the magnetic core 100 , the convenience of fixing the magnetic core 100 can be improved.

[0040] It should be noted that the magnetic core 100 can be clamped with the support member 310 or can be clamped by the support member 310. The embodiment of the present application does not impose too many restrictions on how the support member 310 fixes the magnetic core 100.

[0041] It should be noted that the outer contour of the first limiting boss 320 matches the outer contour of the magnetic core 100 , so that the first limiting boss 320 and the magnetic core 100 can be limited and the first limiting boss 320 and the magnetic core 100 are abutted.

[0042] It should be noted that if Figure 2 and Figure 3As shown, since the flat coil 200 is protruding from the magnetic core 100 , the arc groove 330 is arranged lower than the first limiting boss 320 . By providing the arc groove 330 , more installation space can be reserved for the wound flat coil 200 .

[0043] It should be noted that the above structure of the embodiment of the present application can also facilitate the automated assembly of flat inductors, and the processing cost is lower.

[0044] It is understandable that if Figures 2 to 4 As shown, the support member 310 includes two oppositely arranged support plates 311, which are respectively located on both sides of the first limiting boss 320 and on both sides of the magnetic core 100 of the fixing area 120, and the two support plates 311 are both located between the connection terminals 210 of the two flat coils 200.

[0045] It should be noted that the embodiment of the present application does not limit the height of the support sheet 311 , and those skilled in the art can selectively set it according to actual needs.

[0046] It should be noted that the embodiment of the present application does not limit the width of the support sheet 311, and those skilled in the art can selectively set it according to actual needs.

[0047] It should be noted that the two support sheets 311 can form a clamping area, thereby playing a role in fixing the magnetic core 100 .

[0048] It should be noted that, by disposing the support sheet 311 between the connection terminals 210 of the two flat coils 200 , the magnetic core 100 can be further fixed while facilitating the assembly of the flat coils 200 .

[0049] It is understandable that the upper end of the surface at the connection between the arc groove 330 and the first limiting boss 320 on the same side is set as an inclined surface 340, and the inclined surface 340 is inclined toward the magnetic core 100 of the fixing area 120.

[0050] It should be noted that if Figure 2 and Figure 3 As shown, the arc groove 330 is arranged lower than the first limiting boss 320, and a surface is formed at the connection between the arc groove 330 and the first limiting boss 320. The upper end of the surface is arranged as an inclined surface 340, and the lower end of the surface is arranged as a vertical surface, so that it can further match the contour of the flat coil 200 and reduce the probability of the flat coil 200 being squeezed.

[0051] It is understandable that if Figure 4 and Figure 5 As shown, the base 300 is provided with two first through holes 350 corresponding to the connection terminals 210 of the flat coil 200 .

[0052] The two first through holes 350 can facilitate the assembly of the two terminals 210 of the flat coil 200 and the base 300 .

[0053] It is understandable that the support sheet 311 and the first limiting boss 320 are integrally formed.

[0054] By integrally forming the support sheet 311 and the first limiting boss 320 , the difficulty of assembly can be reduced, and at the same time, the clamping space formed between the support sheets 311 can be more closely matched with the magnetic core 100 .

[0055] It is understandable that if Figure 3 As shown, the base 300 is provided with a plurality of pins 400 , and the plurality of pins 400 are arranged circumferentially along the base 300 ; a first end of the pin 400 is connected to the base 300 , and a second end of the pin 400 passes through the base 300 .

[0056] It should be noted that the pins 400 are used to connect to the circuit board, and the base 300 can also be fixed by the pins 400 .

[0057] It is understandable that if Figure 3 As shown, the first end of the pin 400 is bent, and the second end of the pin 400 is vertically arranged.

[0058] It should be noted that by bending the first end of the pin 400, the connection between the pin 400 and the base 300 is tighter and not easy to fall off. Compared with the straight-insertion pins in the related art, the pin 400 of the present application can reduce the risk of falling off, and the structure is more stable and can increase the pull-out force of the pin 400.

[0059] It should be noted that the embodiment of the present application does not limit the degree of the bending portion of the pin 400, nor the bending angle of the first end, and those skilled in the art can selectively set it according to actual needs. Figure 3 As shown, the first end of the pin 400 is bent 90 degrees and abuts against the inner wall of the slot 360 on the base 300 .

[0060] It is understandable that if Figure 4 As shown, the base 300 is provided with slots 360 corresponding to the pins 400 one by one, and the first ends of the pins 400 are arranged in the corresponding slots 360 .

[0061] By providing the card slot 360 , the pin 400 can be further limited in position, so that the position of the pin 400 is more stable and not easy to fall off.

[0062] like Figure 3 and Figure 4As shown, in some embodiments, a plurality of second limiting bosses 370 are disposed in the base 300 , and a latching slot 360 is formed on each of the second limiting bosses 370 in a one-to-one correspondence.

[0063] It should be noted that if Figure 3 and Figure 4 As shown, in some embodiments, the second limiting boss 370 is tilted near the side of the support sheet 311, so that when the inductor is filled with filler, the filler can more fully fill the base 300. The embodiment of the present application does not limit the tilt angle of the side of the second limiting boss 370, and those skilled in the art can selectively set it according to actual needs.

[0064] It is understandable that if Figures 3 to 5 As shown, the four corners of the bottom surface of the base 300 extend outward to form feet 381.

[0065] For example, Figure 5 As shown, the outer contour of the base 300 is set to be a square, and the four corners of the base 300 extend outward and protrude from the surface of the base 300 to form pads 381.

[0066] By providing the foot 381 , a certain gap is left between the base 300 and the circuit board on which the inductor is mounted, thereby achieving better heat dissipation.

[0067] It is understandable that a plurality of grooves 382 are formed on the ground of the base 300 , some of the grooves 382 are disposed corresponding to the first limiting boss 320 , and some of the grooves 382 are disposed corresponding to the arc-shaped groove 330 .

[0068] By providing the groove 382 , the weight of the base 300 can be reduced while the heat dissipation area can be expanded.

[0069] The above is a specific description of the preferred implementation of the present application, but the present application is not limited to the above-mentioned implementation mode. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the present application. These equivalent deformations or substitutions are all included in the scope defined by the claims of the present application.
