産業上の利用分野
本発明はテレビジョン受像機等に用いられる陰極線管（
以下ＣＲＴと略記する）の偏向ヨークに関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to cathode ray tubes (
The present invention relates to a deflection yoke for a CRT (hereinafter abbreviated as CRT).
従来の技術
従来の偏向ヨークの特に水平コイルを鞍形に巻いたもの
は第３図ないし第６図に示されるようなものであった。2. Description of the Related Art Conventional deflection yokes, particularly those in which a horizontal coil is wound in a saddle shape, are as shown in FIGS. 3 to 6.
ここで、１はフェライト等のコアであシ、このコア１の
上に垂直コイル２が巻かれている。Here, 1 is a core made of ferrite or the like, and a vertical coil 2 is wound on top of this core 1.
そして垂直コイル２が巻かれたコア１は２分割された絶
縁枠３の外面に取り付けられ、絶縁枠３の内面には水平
コイル４が取シ付けられている。The core 1 with the vertical coil 2 wound thereon is attached to the outer surface of an insulating frame 3 divided into two parts, and the horizontal coil 4 is attached to the inner surface of the insulating frame 3.
また、水平コイル４の絶縁枠３の分割線と重なり合う部
分は絶縁の沿面距離が十分確保できないため、絶縁テー
プ６が巻かれていた。In addition, an insulating tape 6 was wrapped around the portion of the horizontal coil 4 that overlapped with the dividing line of the insulating frame 3 because a sufficient creeping distance of the insulation could not be ensured.
発明が解決しようとする問題点
しかしながらこのような従来の偏向ヨークは絶縁テープ
６の巻き付は作業が自動化しに＜＜、作業自体も工数の
かかるものであった。Problems to be Solved by the Invention However, in such a conventional deflection yoke, the winding of the insulating tape 6 cannot be automated, and the work itself requires a lot of man-hours.
本発明はこのような従来の問題点に着目してなされたも
のであり、わずかの作業で絶縁の確保ができる偏向ヨー
クを得るものである。The present invention has been made in view of these conventional problems, and is intended to provide a deflection yoke that can ensure insulation with a small amount of work.
問題点を解決するだめの手段
本発明は２分割された絶縁枠の内面に水平偏向コイルを
設け、水平偏向コイルの絶縁枠の分割線と重なる部分に
水平偏向コイルを挾む断面がコ字状の絶縁体を設けたも
のである。Means to Solve the Problem The present invention provides a horizontal deflection coil on the inner surface of an insulating frame that is divided into two parts, and a U-shaped cross section that sandwiches the horizontal deflection coil in the portion that overlaps with the dividing line of the insulating frame. It is equipped with an insulator.
作 用
本発明は以上の構成より々るため、絶縁は絶縁体によっ
て十分確保され、また絶縁体は水平偏向コイルに被せる
だけでよいので、組み立ては容易なものである。Operation Since the present invention has the above configuration, sufficient insulation is ensured by the insulator, and since the insulator only needs to be placed over the horizontal deflection coil, assembly is easy.
実施例
本発明の一実施例について以下第１図および第２図に沿
って詳細に説明を行う。Embodiment An embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2.
６はフェライト等のコアで、このコア６には垂直偏向コ
イル７が巻かれ、２分割された絶縁枠８゜８′の外面に
取り付けられている。Reference numeral 6 denotes a core made of ferrite or the like, and a vertical deflection coil 7 is wound around this core 6, which is attached to the outer surface of an insulating frame 8.8' which is divided into two parts.
９は水平偏向コイルで、絶縁枠８，８′の内面に取り付
けられている。Reference numeral 9 denotes a horizontal deflection coil, which is attached to the inner surface of the insulating frames 8, 8'.
１０は断面がコ字状の合成樹脂等よりなる絶縁体で、絶
縁枠８，８′の分割線１１と重なる水平偏向コイル９に
嵌め込まれている。Reference numeral 10 denotes an insulator made of synthetic resin or the like having a U-shaped cross section, and is fitted into the horizontal deflection coil 9, which overlaps the dividing line 11 of the insulating frames 8, 8'.
以上の構成の偏向ヨークの組み立てに際しては、サドル
状に巻かれた水平偏向コイル９に絶縁体１０を嵌め合せ
、その後、水平偏向コイル９を絶縁枠８．８′の内側へ
取り付けて組み立てる。When assembling the deflection yoke having the above structure, the insulator 10 is fitted onto the horizontal deflection coil 9 wound in a saddle shape, and then the horizontal deflection coil 9 is attached to the inside of the insulating frame 8.8' and assembled.
発明の効果
以上の説明で明らかなように本発明の偏向ヨークは、２
分割された絶縁枠の内面に水平偏向コイルを設け、水平
偏向コイルの絶縁枠の分割線と重なる部分に水平偏向コ
イルを挾む断面がコ字状の絶縁体を設けているため水平
偏向コイルの絶縁を確保する作業が容易に行えるもので
ある。Effects of the Invention As is clear from the above explanation, the deflection yoke of the present invention has two effects.
A horizontal deflection coil is provided on the inner surface of the divided insulating frame, and an insulator with a U-shaped cross section that sandwiches the horizontal deflection coil is provided in the part that overlaps with the dividing line of the insulating frame of the horizontal deflection coil. The work to ensure insulation can be easily performed.
