Description of the Invention: [Technical Field] The present invention relates to a wound coil set, and more particularly to a coil set suitable for winding a metal foil in a transformer. 5 [Prior Art] There are many shortcomings in the traditional production of coils for large-capacity transformers. For example, the size of the wound conductor is large and the number is too large, the mold installation process is complicated, the rear stage assembly requires welding processing, and the coil stray loss is large. 10 In the large-capacity transformer shown in Fig. 1, because the rated current of the coil is large, the wires of most of the coil windings 91 are assembled by a plurality of wires 911 and wound together. However, since the inside of the coil winding 91 is made of a plurality of wires 911, in the coil winding process, each wire 911 in the coil winding 91 needs to be aligned and wound, which requires more work. At the same time, it will cause the problem of size 15 being too large. In addition, in the conventional method of manufacturing a coil, it is necessary to wind a coil wire around a specific mold (the inner mold 92), and after completing all the windings, attach another coil outer mold, and cast an epoxy. Resin and drying, the coil manufacturing is completed. However, due to the complicated mold installation process, it takes a lot of manpower and 20 hours, which greatly reduces the production efficiency. Furthermore, the coils of the prior art need to be welded and connected, and in addition to requiring more labor, the manufacturing method of the welding may result in poor appearance. Moreover, since the eddy current loss of the coil is proportional to the square of the thickness of the conductor, the thickness of the conventional coil is large, causing a large eddy current, and the efficiency of the transformer is lowered. 201025370 Therefore, there is a need in the art for an innovative winding coil design that solves the above-mentioned shortcomings, achieves the goal of simplifying the coil winding manufacturing process, improving production efficiency, improving the efficiency of the device, and having an excellent appearance. 5 SUMMARY OF THE INVENTION The main object of the present invention is to provide a foil wound coil assembly which can simplify the winding process of the coil. To achieve the above object, the present invention provides a foil wound coil assembly comprising at least two winding coils. Wherein, the winding coils are axially juxtaposed with each other, and each of the 10 winding coils is continuously wound from the inside to the outside by a conductive foil, and the innermost loop of each winding coil is folded outward to form an inner fold. a sheet, the outermost loop of each winding coil is folded outwardly to form an outer flap, and the inner flap and the outer flap are respectively extended toward opposite axial directions. The foil winding coil set provided by the present invention, The feature is that at least two coils of conductive foil refer to the same strip of continuous foil, wherein the inner flap of each wound coil is the outer flap continuously connected to its adjacent winding coil. In the foil winding coil group of the present invention, the angle at which the inner flap is folded is 90 degrees, and the angle at which the outer flap is folded is 90 degrees. Of course, you can also use degrees, or 45 degrees, or 60 degrees to fold. And when one of the inner or outer flaps 20 has a folding angle of 30 degrees, or 45 degrees, or 60 degrees, the other of the folding angles should be relatively ± 30 degrees, or ± 45 degrees, or ±60 degrees.

Preferably, the insulating layer may be a resin impregnated paper having a suitable thickness and maintaining proper insulating ability or generally insulating properties. In addition, the present invention provides an innovative design which solves the problem that the area of the inner and outer flaps is over 5 due to the folding when the width of the conductive box is large. The foil wound coil assembly of the present invention, wherein the inner flap further comprises at least one slit, the conductive foil is divided into at least two foil slices, and preferably the slices are of equal width. Thus, the area of the inner and outer flaps in which the conductive box is folded out can be reduced by more than one-half. The foil winding coil assembly of the present invention further preferably includes a 10 first lead-out board and a second lead-out board, the first lead-out board being electrically connected to the outer flap of the winding coil of the foremost end. The second lead-out plate is electrically connected to the outer flap of the winding coil at the last end. Moreover, the first lead-out board and the second lead-out board are respectively selected from the group consisting of a copper plate and an aluminum plate. The first and second lead plates can be used as assembly fixings to secure the foil winding coil set to the transformer. The foil wound coil group of the present invention is easily wound into a coil because it is made of a conductive foil having a small thickness. Moreover, by folding the inner and outer flaps by folding, the wound coils can be continuously wound without interruption without welding. The longitudinal slit included in the inner flap divides the conductive foil into at least two equal width foil slices, and the area of the inner flap and the outer flap which the conductive foil is folded out is reduced by more than one-half. . Furthermore, the insulating layer of the impregnated resin insulating paper disposed on the side of the conductive box sheet is wound together with the conductive falling sheet, and the winding of the coil is completed after drying without additional epoxy resin. 'To complete the coil manufacturing. In addition, since 5 201025370 is thin and thin, the eddy current loss of the coil is small, which makes the transformer consume less power and improves efficiency. [Embodiment] 5 [Embodiment 1] Referring to Fig. 2' in the present embodiment, a box-wound coil group is provided, which includes three winding coils W. Wherein, the wound coils 1 > 2, 3 are axially juxtaposed with each other, and each of the wound coils 1, 2, 3 is continuously wound from the inside to the outside by a conductive foil 10, 20, 30. The innermost ring 10 101'201, 301 of the winding coils i, 2, 3 is further folded outward to form an inner flap 112131, and the outermost loops 102, 202, 3〇2 of each winding coil 1, 2, 3 are further An outer flap 12, 22, 32' inner flap ιι, 2 ΐ, 31 and outer flaps 12, 22, 32 extend outwardly in opposite axial directions, respectively.

Of course, you can also fold at 30 degrees, or 45 degrees, or 60 degrees. And when the inner flaps u, 2131 20 or one of the flaps 12, 22, 32 of the same winding coil has a folding angle of 30 degrees, or 45 degrees, or 60 degrees, the other is the folding angle It should be relatively ±3〇, or ±45°, or ±60°, as shown in Figure 3, where χ = γ = 90ο. In addition, as shown in FIG. 2, the conductive foils ι〇, 2〇, 3〇 of each winding coil 1 are provided with an insulating layer 13, 23, 33' on one side thereof to electrically insulate the layer. Conductive disclosure 201025370 10, 20, 3G. In the present embodiment, the insulating layers 13 23, 33 mean that the impregnated resin insulating paper can maintain an appropriate insulating ability. The drop-wound coil assembly of this embodiment, as shown in FIG. 2, includes a 5 ❹ 10 15 ❹ mu second second lead-out board 5 ′, the lead-out board 4 is electrically connected to the foremost winding coil.

[Embodiment 2] The sheet winding coil group of the present embodiment is substantially the same as the foil winding coil group of Embodiment 1, but the difference is that, as shown by the circle 4, the foil winding coil group of the present embodiment The conductive foil ΐ θ further includes two longitudinal slits 61 for dividing the conductive foil 10 into at least two foil slices 62 ′ and the foil slices 62 are of equal width. Thus, the area of the inner flap u and the outer flap 12 which the conductive foil folds can be reduced to the original one-third. Therefore, it is possible to solve the problem that the area of the inner flap outer flap 12 is excessively large due to the folding when the width of the conductive sheet 10 is large. As is apparent, the foil-wound coil assembly of the present invention is relatively easy to wind into a coil because it is made of a thin conductive foil.
