損わせるものであつた。 FIG. 1 shows a conventional example of this type of flyback transformer, and 1 is a hollow high-voltage coil bobbin around which a high-voltage coil 2 is wound.In the hollow part of the high-voltage coil bobbin 1, a low-voltage coil (not shown) is installed. Placed. Reference numeral 3 denotes a terminal board in which a multi-voltage rectifier circuit is incorporated, and the end portion of the terminal board 3 is held by a holding piece 5 of a holding plate 4 provided on the high-voltage coil bobbin 1. After passing the protrusion 6 into the hole 7 of the terminal board 3, the protrusion 6 is heat-sealed to fix the terminal board 3 to the high-voltage coil bobbin 1. In general, the high-voltage coil bobbin 1, terminal board 3, etc. are molded products of synthetic resin, so if the terminal board is fixed by heat fusion, the heat fusion part will carbonize and the insulation will drop significantly, causing flyback. This damaged the reliability of the transformer.

のように行なわれる。 FIG. 2 shows an exploded perspective view of the main parts of the flyback transformer of the present invention.
a and 11b are provided. Reference numeral 12 denotes a terminal board in which a multi-voltage rectifier circuit (not shown) is incorporated, and the terminal board 12 has an engaging portion 13 that engages with the pair of arm portions 11a and 11b.
A, 13b and the recess 14, and a terminal holding portion 15 to which a terminal for leading out the multiplied high voltage to the outside is provided. The high voltage coil bobbin 9 and the terminal board 12 are combined as follows.
すなわち、第３図の如く高圧コイルボビン９の
腕部１１ａ，１１ｂのうちＬ字型の腕部１１ａを

嵌まり込んで弾性的に係合する訳である。 That is, as shown in FIG. 3, while hooking the L-shaped arm 11a of the arms 11a and 11b of the high-voltage coil bobbin 9 to the engaging part 13a of the terminal board 12, the other arm 11b having the claw part 16 When pushed in the direction of arrow A, the tapered part of the claw part 16 comes into contact with the engaging part 13b, and the arm part 11b is pushed open by the elastic force of the resin, and when pushed further, the claw part 16 engages as shown in FIG. It fits into the engagement hole 13'b of the portion 13b and engages elastically.
このようにして高圧コイルボビン９とターミナ

ので絶縁性の向上が図れる。 After the high voltage coil bobbin 9 and the terminal board 12 are combined in this way, they are housed in an insulating case 17 as shown in FIG.
4 is provided with a convex portion 18 that is fitted into the concave portion 14.
The terminal board 12 is positioned by the protrusions 18 and 18. FIG. 6 shows the convex portion 18
shows the state before being fitted into the recess 14,
FIG. 7 shows the state after fitting. As can be seen from FIG. 7, the tip of the protrusion 18 of the insulating case 17 is in contact with the bottom of the recess 14 of the terminal board 12, and the terminal board 12 and the insulating case 17 are spaced apart by a certain distance l. It's summery. Therefore, when an insulating resin such as epoxy resin is applied inside the insulating case 17, the resin enters between the insulating case 17 including the convex portion 18 and the terminal board 12, and the creeping surface between the insulating case 17 and the terminal board 12 is Since the distance can be increased, insulation properties can be improved.
また、このとき前記端子保持部１５が、高圧リ
