Therefore, there must be more turns on the secondary side. However, it is easy to wind around the ends of the head and tail. Jumping phenomenon. In order to overcome the above-mentioned image of power jump, the more common solution is to adopt the method shown in FIG. 1 , wherein the transformer i shown in the figure includes a core 10, and the core 10 is provided with a plurality of intervals. The retaining wall 11 and the primary side coil 12 and the secondary side coil 13 are slotted by one of the retaining walls 11 , and the secondary side coil 13 is also divided into a plurality of slots by the retaining walls 11 . Therefore, since the number of turns in a single slot is small, the problem of power jump is effectively reduced. Although the structure of the above-mentioned conventional transformer can achieve the function of reducing the power jump, the opposite figure is an example of the core, the 10 series has five supporting walls, and at least the winding volume of 30 〇/〇 is taken up, and The higher demand will lead to more configuration of the wall 11 and the demand for the production of electronic parts. The practicality and competitiveness of this structure can no longer be attributed to this.

Referring to the two figures, the transformer 2 of the present invention includes a core 20, and the core 20 is wound around a secondary side coil 21, and the outer layer T of the secondary side coil 21 is covered - The first insulating layer 22' is provided with the 200849290-secondary coil 23 around the first insulating layer (1). Further, a second insulating layer 24 may be provided on the outer layer of the primary side coil 23 as needed. Referring to the second circle, the core 20 is implemented as a single-slot wound core, and the secondary coil 21 is wound around the core 20 to form a first right-angled triangle area A1 and a plurality of inclined surfaces. The area A2 and a second right triangle area A3. The winding method of the first right-angled triangular area A1 is formed by the i-th ring being parallelized from one end of the core 20 to the other end to form a layer, and the starting winding point of the next layer of bending is selected as the most Close to the last winding point of the previous layer, and wound to the end of the core 2〇 in a winding direction opposite to the previous layer, repeating the winding method to wind the outer layer; and the slope area A2 is along the line The beveled surface of the right-angled triangular region is wound; thus the remaining unwound region is then gradually wound inwardly out of the right-angled triangular region A3 in a winding sequence opposite to the first right-angled triangular region A1.

The circle is formed by (a) and the other is oblique (four), and the beveled heart is wound outward in order from 200849290. The younger 21 to the 25th circle form a bevel area A2, which is wound around the 66th to the 70th circle according to the bevel winding method. A plurality of slope areas A2 are accumulated. At this time, the remaining portion has only one position of the inverted right-angled triangle, and then is arranged to the 85th turn with reference to the winding manner opposite to the right-angled triangular area A1 described above, thereby completing the winding of the secondary-side coil 21 as described above. The bevel area A2 of the present invention starts to be slanted around the 5th turn, and is reciprocated a total of u times. The effect of the winding is the same as that of the conventional technique in which the iron core is wound into 55 grooves by a plurality of retaining walls. In addition, the front and rear two right-angled triangle areas A3 are also equivalent to two slots, so the voltage conversion efficiency produced by this is better than the conventional split-type transformer, but the volume is reduced by at least 3〇%. As described, the coil winding method used in the transformer of the present invention includes the oblique order arrangement, so that the number of adjacent windings at the time of winding is relatively close and no jump phenomenon occurs, so that the conventional transformer can be omitted. The wall-casting structure 'especially because of the addition of two right-angled areas to improve efficiency', the present invention has higher efficiency and smaller size than the conventional transformer system. For the production of the production can be described together with the economic benefits, but also to meet the miniaturization of electronic components now to be described above are only illustrative and not a limiting sense. Any changes or equivalents to the invention may be made without departing from the spirit and scope of the invention.
