[0021] Please refer toFigure 1 As shown, an embodiment of this utility model provides a miniature coil frame that facilitates automatic winding, including an insulating base plate 1 with a through hole 2 at its center. Copper pillars 3 are respectively provided at the front and rear ends of the insulating base plate 1, and folding portions 4 are respectively provided on the left and right sides of the insulating base plate 1. Each folding portion 4 is provided with an insulating winding post 5, and a copper needle 6 (with magnetic effect, similar to the function of silicon steel sheets) is coaxially embedded within the insulating winding post 5. Specifically, the insulating winding post 5 in this embodiment of the utility model has a "T"-shaped structure, which, together with the folding portion 4 at its bottom, forms an "I"-shaped structure, facilitating coil positioning.

Figure 2 As shown, during winding, the folded part 4 can be folded downwards to the folded position, so that the two folded parts 4 are positioned opposite each other. At this time, the two insulating winding posts 5 are away from each other. The coil frame can be installed on the positioning fixture of the automatic winding machine, using the two copper posts 3 as the head and tail winding posts, and automatically winding and automatically completing the head and tail winding in a double-sided winding method. After the coil is wound, the folded part 4 is folded upwards to the unfolded position. At this time, the two folded parts 4 and the insulating base plate 1 are on the same plane, and the coil frame can be assembled on the miniature outer frame 7, as shown. Figure 3 As shown (coil not shown).

[0023] Furthermore, the bottom end of the copper pillar 3 extends from the bottom of the insulating base plate 1, so that the bottom end of the copper pillar 3 can be used as a terminal to connect to the PCB board located at the bottom of the miniature outer frame 7, such as... Figure 4 As shown, the miniature outer frame 7 is provided with a corresponding connection hole 8 for the copper post 3 to pass through. The bottom end of the copper needle 6 can also pass through the bottom of the insulating base plate 1.
