本考案はテレビジヨン受像機において使用する
フライバツクトランスに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flyback transformer used in a television receiver.

また適当な対策とは言えなかつた。 FIG. 1 shows a side cross-sectional view of a conventional flyback transformer, in which a low-voltage coil 3 is placed in the low-voltage side portion of the high-voltage coil 1 in the hollow of a split-type high-voltage coil bobbin 2 around which the high-voltage coil 1 is wound. A low-voltage coil bobbin 4 wound with is inserted and assembled, and a ferrite core 5 is passed through the hollow portion of the low-voltage coil bobbin 4 and molded with resin (not shown). However, even if the part (A) in FIG. 1 is filled with resin, there is a slight gap between the ferrite core 5 and the low-voltage coil bobbin 4.
There was a drawback that corona discharge occurred in the gap near the high voltage portion of the high voltage coil 1. Therefore, as a countermeasure to this problem, a conventional flyback transformer as shown in the side cross-sectional view of FIG. This prevents the occurrence of corona discharge as described above, but the structure of winding the low voltage coil 3 in this way requires a complicated winding method and it is difficult to use automatic winding, so this is also an appropriate countermeasure. I couldn't say that.

特徴としている。 In FIG. 3, which shows a side sectional view of the flyback transformer of the present invention, in which the same parts as those in FIG. 6 is tightly wound around the low voltage coil bobbin 4,
It is characterized in that the metal foil sheet 6 is led to the ground by a lead wire 7a which is led to the ground to set it at ground potential.

めに生じることはない。 Next, the method of assembling the main parts of the flyback transformer of the present invention will be explained. As shown in FIG. 4, the lead wire 7a is connected to the flange 4a of the low voltage coil bobbin 4.
The lead wire 7a is passed through the notch 4c of the flange 4b, then through the notch 4d of the flange 4b, and is hung on the small protrusion 4e formed on the flange 4b, and passed through the notch 4d again, and wound between the flanges 4b and 4a to form a low-voltage coil, and then led out through the notch 4f of the flange 4a. After that, the metal foil sheet 6 is wrapped around the entire outer periphery of the cylindrical part 4g of the low-voltage coil bobbin 4. This metal foil sheet 6 is made of copper or the like, and is wrapped around the edge 6a (hatched part) using an insulating sheet 8 with adhesive applied on both sides so that the metal foil sheet 6 does not form a closed loop. The insulating sheet 8 is used because if it is not insulated, a short circuit will occur due to electromotive force, and the flyback transformer will no longer function. Then, the lead wire 7 that was hung on the small protrusion 4e is removed and connected to the metal foil sheet 6 by soldering or the like, and the metal foil sheet 6 is set to earth potential. If such a metal foil sheet 6 is kept at earth potential and wrapped tightly around the low-voltage coil bobbin 4, then when the sheet is resin molded, the space between the metal foil sheet 6 and the high-voltage coil bobbin 2 is filled with resin (not shown) without any gaps, and no corona discharge occurs in this area.
Furthermore, corona discharge in the small gap between the low voltage coil bobbin 4 and the ferrite core 5 as described above does not occur because the metal foil sheet 6 blocks the induced voltage.

果があり、極めて有用である。 As described above, the flyback transformer of the present invention has the effect of reliably preventing the occurrence of corona discharge in the flyback transformer with a simple structure, and is extremely useful.
