The invention relates to a wire frame structure of a magnetic component and a winding method thereof, in particular to a wire frame structure for facilitating winding of a magnetic component and a winding method thereof.

The wire frame structure of the existing magnetic component is disclosed in the Patent No. I501266, I493578, I471879, M502237, and M491933 of the Republic of China. The wire frame structure includes a winding portion and a plurality of wire outlet portions, and the winding portion provides At least one wire is wound thereon, and the outlet portion is fixed with a plurality of conductive pins to provide the wire after the winding is completed, and the end of the wire is wound thereon, and then the wire is electrically connected to the wire. The feet form an electrical connection. However, each of the conductive pins of the wire frame structure is fixedly attached to the wire frame structure after the wire frame structure is completed. In this way, the user needs to pay special attention to the position of the conductive pins when the wire is wound by the user, and whether the conductive pins conform to the winding jig used at present, which is unfavorable for implementation.

Wherein the bobbin includes at least one winding region, the aluminum conductor includes a winding segment at least one turn around the winding region, and two connecting segments at the end of the aluminum conductor.
