【考案の詳細な説明】 本考案は電気機器、例えばカラーテレビジョン受像機に
使用する偏向ヨーク装置の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in deflection yoke devices used in electrical equipment, such as color television receivers.

カラーテレビジョン受像機は、カラー受像管に偏向ヨー
ク装置を取付けており、一般に水平偏向コイルと垂直偏
向コイルの間に磁性体を配置させ画面左右の偏向糸巻歪
を補正する偏向ヨーク装置に於いては、磁性体の取付は
位置が補正量に大きく影響を与えるので、正確に且つ確
実に位置決めを行なう必要がある。Color television receivers have a deflection yoke device attached to the color picture tube. Generally, a magnetic material is placed between the horizontal deflection coil and the vertical deflection coil, and the deflection yoke device corrects deflection pincushion distortion on the left and right sides of the screen. When attaching a magnetic body, the position greatly affects the amount of correction, so it is necessary to position the magnetic body accurately and reliably.

従来より偏向ヨーク装置に於ける磁性体の取付けとして
は第１図と、第１図の一部拡大図である第２図で説明す
ると下記の例がある。Conventionally, there are the following examples of mounting a magnetic body in a deflection yoke device, which will be explained with reference to FIG. 1 and FIG. 2, which is a partially enlarged view of FIG.

二分割された漏斗状の合成樹脂製コイルセパレータ１，
１の傾斜部の互いに対向する端部に凹形の切り欠き２，
２とこの切り欠き２，２周辺に設けられ磁性体４が挿入

けた突堤６，６をコイルセパレータ１と一体に形威し磁
性体４を溝５．５に挿入後接着剤で固定していた。Two-part funnel-shaped synthetic resin coil separator 1,
concave notches 2 at mutually opposing ends of the inclined portion of 1;
2 and grooves 5, 5 provided around the notches 2, 2, into which the magnetic material 4 can be inserted and held, and jetties 6, 6 provided facing each other are formed integrally with the coil separator 1, and the magnetic material 4 is formed integrally with the coil separator 1. 4 was inserted into the groove 5.5 and fixed with adhesive.

この様な構成での磁性体４の位置決め保持構造では、コ

A gap 7 is formed at the junction of each coil separator 1, 1.

ここに間隙７ができることは磁性体４の挿入時正確な位
置決めが不可能で、精度は極めて不正確になることであ
り、偏向糸巻歪の補正に対してもバラツキが大きくなる
欠点があった。The gap 7 created here makes it impossible to accurately position the magnetic body 4 when it is inserted, resulting in extremely inaccurate accuracy, and has the drawback of large variations in correction of deflection pincushion distortion.

磁性体４は溝５に挿入後接着剤にて固定するが、完全に
硬化する迄磁性体４の移動が発生しない様に注意して放
置しなければならず放置場所が必要になり工数的にも増
加する等の欠点があった。The magnetic material 4 is fixed with adhesive after being inserted into the groove 5, but care must be taken to prevent the magnetic material 4 from moving until it is completely cured, which requires a place to store it, which reduces man-hours. There were disadvantages such as an increase in

又、コイルセパレータ１に溝５を一体に設けることは金
型が複雑になり高価になるばかりでなく、複雑になれば
金型の寿命が短くなる等の金型構造上、および金型寿命
上の欠点があった。Moreover, providing the groove 5 integrally with the coil separator 1 not only complicates the mold and increases its cost, but also increases the complexity and shortens the life of the mold, which is detrimental to the structure of the mold and the lifespan of the mold. There was a drawback.
