For example, the chinese utility model "micro inductor" with the authorized publication number CN202749186U, the chinese utility model "inductance capable of increasing inductance and current under height limitation" with the authorized publication number CN207183049U, and the chinese utility model "a flat single-turn inductor with magnetic powder glue encapsulation air gap" with the authorized publication number CN204010944U all belong to the aforementioned chip inductor.

The applicant has also involved in the production activity a chip inductor as shown in fig. 1, which has a flat plastic package base 1 ', the bottom surface of which plastic package base 1' is provided with solder fillets 11 ', and the top surface of plastic package base 1' is filled with a central conductor 2 'forming a series circuit with solder fillets 11'. The central conductor 2' is a flat coil structure constructed by ferrite cores, and specifically adopts an assembly structure as shown in fig. 2:

adopting a circular gasket 20 ' made of conductive metal, forming three folded foot ends 21 ' with equal distance distribution in a herringbone shape on the circumference of the circular gasket 20 ' along the radial direction, and placing a disc-shaped ferrite core 22 ' with the same diameter on the circular gasket 20 '; the three bent leg ends 21 ' are sequentially bent towards the top surface of the ferrite core 22 ' along the edge of the circular gasket 20 ', and the overlapped parts between the bent leg ends 21 ' are spaced by adopting insulating rubber sheets 23 ' made of polyamide; the three bent leg ends 21 'form a flat coil wrapped on the ferrite core 22' in cooperation with the circular pad 20 ', and the ends of the leg ends 21' respectively extend out of the edge of the ferrite core 24 'to form connection terminals matched with the solder legs 11'.
