[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, in the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "front", "back", "left", "right", "up", "down", etc. is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] See also Figure 1 As shown, an embodiment of the present invention provides a micro coil skeleton that is convenient for automatic winding, including an insulating base plate 1, and a through hole 2 is opened at the center of the insulating base plate 1. 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. Insulating winding posts 5 are provided on the two folding portions 4, and copper needles 6 are coaxially embedded in the insulating winding posts 5 (magnetic effect, similar to that of silicon steel sheets). Specifically, the insulating winding posts 5 in the embodiment of the present invention are of a "T"-shaped structure, which can cooperate with the folding portion 4 at the bottom thereof to form an "I"-shaped structure, so as to facilitate the limiting of the coil.

[0026] The folding portion 4 is flexibly connected to the insulating bottom plate 1, so that the folding portion 4 can be folded back and forth relative to the insulating bottom plate 1 to switch back and forth between the folded position and the unfolded position. Figure 2 As shown, when winding, the folding part 4 can be folded down to the folded position, so that the two folding parts 4 are arranged opposite to each other. At this time, the two insulating winding posts 5 are separated from each other. The coil skeleton can be installed on the positioning fixture of the automatic winding machine, and the two copper posts 3 are used as the head and tail winding posts. The double-sided winding method is used to automatically wind and automatically complete the head and tail wire arrangement. After the coil is wound, the folding part 4 is folded upward to the unfolded position. At this time, the two folding parts 4 and the insulating bottom plate 1 are located on the same plane, and the coil skeleton can be assembled on the micro outer frame 7, as shown in FIG. Figure 3 As shown (coil not shown).

[0027] Furthermore, the bottom end of the copper column 3 passes through the bottom of the insulating base plate 1 so that the bottom end of the copper column 3 can be connected to the PCB board arranged at the bottom of the micro frame 7 as a wiring terminal. Figure 4 As shown, the micro frame 7 is provided with a connection hole 8 for the copper column 3 to pass through. The bottom end of the copper needle 6 can also pass through the bottom of the insulating bottom plate 1. It is only necessary to provide a positioning hole 9 for the copper needle 6 to be inserted on the micro frame 7, so that the copper needle 6 can be used to position the coil skeleton during assembly.

[0028] Preferably, the insulating base plate 1, the folding portion 4 and the insulating winding post 5 in the embodiment of the present invention are integrated, and the structural strength is higher. For reference, the insulating base plate 1, the folding portion 4 and the insulating winding post 5 can be made of PA66 plastic material, which has plasticity, high mechanical strength, good toughness, and high heat resistance.

[0029] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the technical solutions and core ideas of the present invention. Ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
