図である。The structure of the conventional example and its problems The conventional flyback transformer of this type is structured as shown in Figs. 1 to 3. Fig. 1 is a wiring diagram of this type of flyback transformer. A high voltage coil L2 magnetically coupled to the coil L1 is divided into a plurality of parts, and a diode D is connected in series to the high potential side of each winding of the high voltage coil L2. FIG. 2 is a front external view showing a part of a high voltage coil of a conventional flyback transformer of this type in cross section.

ィルム２を示しており、表面はフラットなものである。In this case, the method of drawing out the copper wire at the beginning and end of each winding is as shown in Fig. 3. At any drawing point of the insulating film 2 wound around the high-voltage bobbin 1, the fixing tape 3 is placed over the copper wire 4. A method of fixing the lead-out portion of the copper wire by pasting it is used. FIG. 4 shows the insulating film 2, which has a flat surface.

ければならないという欠点があった。In this configuration, it is necessary to bend the copper wire 4 at right angles within the area of the fixing chip 13 using an arbitrary drawing device, and at the same time, it is necessary to apply the fixing tape 3. Another disadvantage is that the operation of the winding wiring machine must be temporarily stopped during tape application.
