【考案の詳細な説明】
本考案は小形化し低コスト化を計っ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 that is smaller in size and lower in cost.
従来におけるフライバックトランスとしては第１図に示
すように構成されていた。A conventional flyback transformer was constructed as shown in FIG.
コ字状のコアを２個突合せて構成した磁心１の磁脚には
、低圧コイル２を巻回した低圧ボビン３と、高圧コイル
４を巻回した高圧ボビン５が装着されて構成されていた
。A low voltage bobbin 3 around which a low voltage coil 2 was wound and a high voltage bobbin 5 around which a high voltage coil 4 was wound were attached to the magnetic legs of a magnetic core 1 which was constructed by butting two U-shaped cores together. .
上記低圧ボビン３は端子ピン６を植設した下鍔７と、こ
の下鍔７との間で低圧コイル２の巻回部を形成する中間
鍔８と、この中間鍔８上に磁心１と高圧ボビン５間には
まりこむ筒状部９によって形成され、この筒状部９の先
端に保合部１０を設けて構成されていた。The low voltage bobbin 3 has a lower flange 7 in which a terminal pin 6 is implanted, an intermediate flange 8 which forms a winding part of the low voltage coil 2 between the lower flange 7, and a magnetic core 1 and a high voltage coil on the intermediate flange 8. It is formed by a cylindrical part 9 that fits between the bobbins 5, and a retaining part 10 is provided at the tip of the cylindrical part 9.
また、高圧ボビン５は両端の鍔１１間に多数の中間鍔１
１を設けた分割ボビンより構成され、中心孔１２の一部
に低圧ボビン３の係合部１０と係合される係合突条１３
を設けて構成されていた。Moreover, the high pressure bobbin 5 has a large number of intermediate flanges 1 between the flanges 11 at both ends.
1, and an engaging protrusion 13 that is engaged with the engaging portion 10 of the low pressure bobbin 3 in a part of the center hole 12.
It was configured with the following.
この上うな構成では、低圧コイル２と高圧コイル４との
間に低圧ボビン３の中間鍔８と、高圧ボビン５の一端の
端１１が存在することになり、不必要な絶縁厚みをもつ
ことになり、全体的に大形化する欠点があった。Moreover, in such a configuration, the intermediate collar 8 of the low voltage bobbin 3 and the end 11 of one end of the high voltage bobbin 5 are present between the low voltage coil 2 and the high voltage coil 4, resulting in unnecessary insulation thickness. However, it had the disadvantage of becoming larger overall.
また、低圧ボビン２は２方向の成型となり、成型効率が
低下して量産性が計れず、このためコスト面で不利にな
るものであった。Furthermore, the low-pressure bobbin 2 is molded in two directions, which reduces molding efficiency and makes it impossible to measure mass production, which is disadvantageous in terms of cost.
本考案は以上のような従来の欠点を除去するものである
。The present invention eliminates the above-mentioned drawbacks of the prior art.
以下、本考案の一実施例を図面第２図により説明する。An embodiment of the present invention will be described below with reference to FIG. 2.
１４はフェライトなどによって形成されたコ字状コアを
２個突合せて構成した口字状の磁心で、この磁心１４の
一磁脚には高圧コイル１５を巻装した高圧ボビン１６、
低圧コイル１７を巻装した低圧ボビン１８が装着されて
いる。Reference numeral 14 denotes a square-shaped magnetic core constructed by butting together two U-shaped cores made of ferrite or the like, and a high-voltage bobbin 16 with a high-voltage coil 15 wound around one magnetic leg of the magnetic core 14;
A low voltage bobbin 18 wound with a low voltage coil 17 is attached.
上記高圧ボビン１６は複数個の鍔１９を等間隔に設け、
この一端に筒状部２０を突出させた構成となっている。The high pressure bobbin 16 has a plurality of flanges 19 arranged at equal intervals,
It has a configuration in which a cylindrical portion 20 is protruded from one end.
一方、低圧ボビン１８は端子ピン２１を植設した鍔２２
の一方に筒状部２３を設けた構成となっており、この筒
状部２３に低圧コイル１７が巻回される。On the other hand, the low pressure bobbin 18 has a flange 22 in which a terminal pin 21 is embedded.
A cylindrical portion 23 is provided on one side of the cylindrical portion 23, and a low voltage coil 17 is wound around the cylindrical portion 23.
そして、この低圧ボビン１８は高圧ボビン１６の筒状部
２０の外周にはめこまれ、低圧コイル１７の一端は高圧
ボビン１６の一端の鍔１９に当接する。The low-pressure bobbin 18 is fitted into the outer periphery of the cylindrical portion 20 of the high-pressure bobbin 16, and one end of the low-pressure coil 17 abuts against the collar 19 at one end of the high-pressure bobbin 16.
このように本考案のフライバックトランスは構成される
ため、高圧コイルと低圧コイルとの間に高圧ボビンの一
端の鍔が介在するだけであるため、全体の高さを小さく
することができ小形化が計れることかできる。Since the flyback transformer of the present invention is configured in this way, only the flange at one end of the high-voltage bobbin is interposed between the high-voltage coil and the low-voltage coil, so the overall height can be reduced, making it more compact. can be measured.
また、低圧ボビンは一方向の成型が可能となり、端子ビ
ンの打込み作業も行ないやすく、生産性に優れコストの
低減化を計る上で著しく有利となる。In addition, the low-pressure bobbin can be molded in one direction, making it easier to drive the terminal pins, resulting in excellent productivity and a significant advantage in reducing costs.
