第１図に従来の偏向調整装置を示す。FIG. 1 shows a conventional deflection adjustment device.
偏向コイルたとえば水平偏向コイルは左右一対のコイル
１゜２からなり、受像管に取り付けられている。A deflection coil, for example a horizontal deflection coil, consists of a pair of left and right coils 1°2, and is attached to the picture tube.
この一対のコイル１，２は並列接続され、端子３，４に
偏向回路の出力が加えられて動作する。The pair of coils 1 and 2 are connected in parallel and operate by applying the output of the deflection circuit to terminals 3 and 4.
上記コイル１，２のそれぞれの一端には振幅調整コイル
５が押入され、この振幅調整コイル５内にコア６が移動
自在に設けられている。An amplitude adjustment coil 5 is inserted into one end of each of the coils 1 and 2, and a core 6 is movably provided within the amplitude adjustment coil 5.
上記振幅調整コイル５の中点タップＴは上記端子４に接
続される。A midpoint tap T of the amplitude adjustment coil 5 is connected to the terminal 4.
したがってテレビジョン受像機の受像管画面のラスク位
置、振幅を最適に調整するには、上記コア６を移動させ
ることにより簡単に行なうことができる。Therefore, the rask position and amplitude of the picture tube screen of the television receiver can be optimally adjusted by simply moving the core 6.
しかしながらこの構成では一対のコイル１２が並列接続
の場合にのみ使用でき直列接続の場合には使用できなか
った。However, this configuration can only be used when the pair of coils 12 are connected in parallel, and cannot be used when the pair of coils 12 are connected in series.
本発明は偏向コイルがトロイダル巻きであり、一対のコ
イルが直列接続されている場合にラスタの振幅を容易に
調整できる偏向調整装置を提供するものであり、以下本
発明の一実施例を図面とともに説明する。The present invention provides a deflection adjustment device that can easily adjust raster amplitude when the deflection coil has a toroidal winding and a pair of coils are connected in series.One embodiment of the present invention will be described below with reference to the drawings. explain.
第２図において、コア８に偏向コイルたとえば水平偏向
コイルを２分割した一対のコイル９，１０がトロイダル
状に巻装さたている。In FIG. 2, a pair of coils 9 and 10, which are obtained by dividing a deflection coil, for example, a horizontal deflection coil into two, are wound around a core 8 in a toroidal shape.
このうちコイル１０は振幅調整コイル１１と直列接続さ
れ偏向回路に端子１２．１３を介して接続される。Of these, the coil 10 is connected in series with the amplitude adjustment coil 11 and connected to the deflection circuit via terminals 12 and 13.
一方上記コイル９の両端には振幅調整コイル１４が接続
されループを作る。On the other hand, amplitude adjustment coils 14 are connected to both ends of the coil 9 to form a loop.
上記両振幅調整コイル１１１４はほぼ同一の形状をなし
、−直線上に隣接して配され、両コイル内部に一つのコ
ア１５が移動自在に設けられる。Both amplitude adjustment coils 1114 have substantially the same shape, are arranged adjacent to each other on a straight line, and one core 15 is movably provided inside both coils.
上記コイル１０に偏向回路からの出力が流れれば偏向磁
束１６が生じ、コイル１０とコイル９とはコア８により
磁気的に結合し、コイル９に偏向磁束１７が発生するよ
うに逆起電流が流れる。When the output from the deflection circuit flows through the coil 10, a deflection magnetic flux 16 is generated, the coil 10 and the coil 9 are magnetically coupled by the core 8, and a back electromotive current is generated such that a deflection magnetic flux 17 is generated in the coil 9. flows.
この状態でたとえば上記コア１５を振幅調整コイル１１
側へ移動させれば、コイル１１のインダクタンス値は大
きくなり、逆に振幅調整コイル１４のインダクタンス値
は小さくなる。In this state, for example, the core 15 is connected to the amplitude adjustment coil 11.
If it is moved to the side, the inductance value of the coil 11 increases, and conversely, the inductance value of the amplitude adjustment coil 14 decreases.
したがってコイル１０を流れる電流は減少し、コイル９
を流れる電流は増大する。Therefore, the current flowing through coil 10 decreases and coil 9
The current flowing through increases.
このためコイル１０によって発生する偏向磁束１６は弱
く、コイル９によって発生する偏向磁束１７は強くなる
。Therefore, the deflection magnetic flux 16 generated by the coil 10 is weak, and the deflection magnetic flux 17 generated by the coil 9 is strong.
このように偏向コイルのインダクタンスのばらつき及び
その他の原因によるラスタ振幅のアンバランスを正しく
調整できる。In this way, it is possible to correctly adjust the raster amplitude imbalance due to variations in the inductance of the deflection coil and other causes.
なおこのような接続における偏向回路出力側から見た偏
向コイルのインピーダンスは偏向周波数においてはコイ
ル９，１０が直列接続の場合のインピーダンスと等価で
ある。Note that the impedance of the deflection coil viewed from the output side of the deflection circuit in such a connection is equivalent to the impedance when the coils 9 and 10 are connected in series at the deflection frequency.
したがって偏向コイルが二分割され直列接続される場合
において本発明の回路は犬なる効果を奏する。Therefore, when the deflection coil is divided into two parts and connected in series, the circuit of the present invention has a significant effect.
なお水平偏向コイルに限らず垂直偏向コイルにも使用で
きる。Note that it can be used not only for horizontal deflection coils but also for vertical deflection coils.
以上のように本発明によれば二分割され直列接続された
偏向コイルのインダクタンス値を微調整でき受像管のラ
スタを正しく位置させることができるものである。As described above, according to the present invention, the inductance value of the deflection coil divided into two and connected in series can be finely adjusted, and the raster of the picture tube can be correctly positioned.
