本考案は絶縁ケースに改良を加えて磁心と高圧コイルの
高圧部との絶縁性の向−ヒと磁心の固定を計るように構
成したフライバッ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 in which the insulating case is improved to improve the insulation between the magnetic core and the high-voltage portion of the high-voltage coil and to secure the magnetic core.
従来のフライバックトランスとしては第１図。Figure 1 shows a conventional flyback transformer.
第２図に示すように構成されていた。It was constructed as shown in Figure 2.

下端開口部に底板８を取付けて構成されていた。That is, a low-voltage bobbin 4 and a high-voltage coil 5 each have a low-voltage coil 3 wound around one magnetic leg of the magnetic core 2, which is formed by abutting two U-shaped cores made of ferrite or the like and forming an opening shape using a fastening fitting 1. A split-type high-pressure bobbin 6 that has been wound in sections is attached, and this is housed in an insulating case 7, and a bottom plate 8 is attached to the opening at the lower end of the insulating case 7.

た。A storage section 10 for storing a rectifying diode 9 is provided at the upper end of the high-pressure bobbin 6, and the insulating goosef is formed into a shape that follows the magnetic core 2, the low-pressure bobbin 4, and the high-pressure bobbin 6. Since the insulation creepage distance between the diode 9 connected to the high voltage output of the high voltage coil 5 and the magnetic core 2 is linear and short as shown by arrow A, dielectric breakdown often occurs in this part. Met.
しかも、磁心２と絶縁ケース７とはボビンを装着しない
磁心２の磁脚と絶縁ケース７とがはまり合うだけである
ため、磁心２の寸法精度のばらつきなどによってがたつ
きやすいものとなっていた。Furthermore, since the magnetic core 2 and the insulating case 7 are simply fitted together by the magnetic legs of the magnetic core 2 to which no bobbin is attached and the insulating case 7, the magnetic core 2 tends to wobble due to variations in the dimensional accuracy of the magnetic core 2. .

とはない。With this configuration, the diode 18 and the magnetic core 11, which become the high voltage part of the high voltage coil 15, are connected to the insulating case 2.
The insulation creepage distance becomes significantly longer as shown by the arrow B due to the 0 protrusions 21, and no dielectric breakdown occurs in this portion.
