[0023] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0024] like Figures 1 to 5 As shown, an embodiment of this utility model provides a novel magnetic core electroplating structure based on magnetic adhesive inductor, including a magnetic core body 1, a coil 2 wound on the magnetic core body 1, solder 3 soldered on the magnetic core body 1, and magnetic adhesive 4 coated on the surface of the coil 2.

[0025] In this embodiment of the utility model, based on the existing method of not electroplating the four corners, the wire slot opening is also not electroplated. When the machine winds the wire and puts it into the wire slot, and then solders it with a soldering iron 3, the lack of electroplating in the wire slot will keep the solder away from the wire slot opening, preventing it from flowing to the coil 2 and causing a short circuit. In addition, the soldering iron tip does not need to be moved to the wire slot opening during the process, avoiding friction between the soldering iron tip and the wire diameter, which is less likely to cause wire breakage. In the mass production of magnetic glue inductors, soldering iron technology is used, which has a low cost. Soldering iron can precisely control the heat, reduce thermal damage to nearby sensitive components, meet the needs of industrial mass production and facilitate worker maintenance. By adopting the method of not plating the wire slot opening, production efficiency is improved, human operation differences are prevented, and the defect rate of short circuits and short wires is reduced, thereby improving product reliability and market competitiveness.

[0026] Figures 1 to 5As shown, the magnetic core body 1 is fixedly provided with a plurality of support frames 7, each of the support frames 7 is fixedly provided with a round sleeve 8, the inner wall of each of the round sleeves 8 is connected with a spring 9, the end of each of the springs 9 is connected with a telescopic block 10, a plurality of the telescopic blocks 10 are fixedly provided with a limiting shell 11, the limiting shell 11 is provided with a support mechanism, the support mechanism is used for supporting the limiting shell 11 to move and fix, the magnetic core body 1 is symmetrically fixedly provided with two connecting frames 5, the ends of the two connecting frames 5 are fixedly provided with a frame block 6, the magnetic core body 1 and the frame block 6 are provided with a gap matched with the limiting shell 11, the support mechanism comprises a frame plate 12 fixedly provided on the limiting shell 11, the frame plate 12 is fixedly provided with a round shell 13, the support mechanism further comprises a top frame 15 fixedly provided on the two connecting frames 5, the inner side of the top frame 15 is movably provided with a support bolt 14, the support bolt 14 is provided with a thread matched with the top frame 15, and the bottom end of the support bolt 14 is movably located on the inner side of the round shell 13.

[0027] In the embodiment of the utility model, the staff twists out the top frame 15 through the thread of support bolt 14, makes support bolt 14 no longer fix the limiting shell 11 through the top frame 15, makes the limiting shell 11 move along the gap between the magnetic core body 1 and the frame block 6 under the elastic force of spring 9, makes the limiting shell 11 abut on the bottom end of magnetic core body 1, thereby when the magnetic glue 4 is applied to coil 2, the limiting shell 11 can limit the flowing of the un-solidified magnetic glue 4, prevents the uneven phenomenon, thereby can improve the mechanical strength, heat dissipation performance and electrical characteristics of inductor.

[0028] Figures 1 to 5 As shown, the top end of the magnetic core body 1 is provided with a plurality of through holes, the outer side of the round shell 13 is movably provided with a movable frame 16, and a plurality of end portions of the movable frame 16 are each fixedly provided with a rubber plug 17 matched with the through holes.

[0029] In the embodiment of the utility model, when the limiting shell 11 abuts on the bottom end of the magnetic core body 1, the rubber plug 17 is driven out of the inner side of the through hole by the movable frame 16, the magnetic core glue is injected into the space between the coil 2 and the limiting shell 11 through the through hole by the injection tool, the magnetic glue 4 fills the space between the coil 2 and the limiting shell 11, thereby the uniformity of the magnetic glue 4 acting on the coil 2 can be improved.

[0030] Working principle: on the basis of not electroplating four corners, the wire slot is not electroplated, the machine winding puts the wire into the wire slot, and then the tin is welded by the soldering iron 3. Because the wire slot is not electroplated, the tin is far away from the wire slot, which can prevent the tin from flowing to the coil 2 and causing short circuit. The staff twists out the top frame 15 by the threaded part of the supporting bolt 14, so that the supporting bolt 14 no longer fixes the limiting shell 11 through the top frame 15. The limiting shell 11 moves along the gap between the magnetic core body 1 and the frame block 6 under the elastic force of the spring 9, and abuts against the bottom end of the magnetic core body 1. The rubber plug 17 is driven by the movable frame 16 to move out of the inner side of the through hole. The magnetic core glue is injected into the space between the coil 2 and the limiting shell 11 through the through hole by the injection tool, so that the magnetic glue 4 fills the space between the coil 2 and the limiting shell 11. The rubber plug 17 is blocked in the through hole by the movable frame 16. When the magnetic glue 4 acts on the coil 2, the limiting shell 11 can limit the flow of the un-solidified magnetic glue 4, and prevent unevenness. When the magnetic glue 4 solidifies, the supporting bolt 14 is moved upward and fixed on the top frame 15, so that the limiting shell 11 is separated from the solidified magnetic glue 4.

[0031] The above is the preferred embodiment of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered as the protection scope of the present application.
