この考案は磁気シールドを内設するカラー受像管の改良
に関する。[Detailed Description of the Invention] This invention relates to an improvement of a color picture tube incorporating a magnetic shield.
従来インナーシールドは、プレス加工または溶接によっ
て−ケの構体を形成している。Conventionally, an inner shield has a structure formed by press working or welding.
このインナーシールドをフレームに取付けるにあたり、
後工程の炉通過時の熱によるインナーシールドの変形が
フレームを介してシャドウマスクに伝えることによりミ
スランディングを生じる。When installing this inner shield to the frame,
The deformation of the inner shield due to heat during passage through the furnace in the post-process is transmitted to the shadow mask via the frame, causing mislanding.
また前記ミスランディングの原因をなくすため、磁気シ
ールドを分割し、フレームに伝える力を分散しているが
、前記一体の構体より磁気シールド効果が低い。In addition, in order to eliminate the cause of mislanding, the magnetic shield is divided to disperse the force transmitted to the frame, but the magnetic shielding effect is lower than that of the integrated structure.
本考案は以上のような欠点に鑑みてなされたもので、イ
ンナーシールドの形状によってミスランディングを少な
く腰磁気シールド効果を一体の構造と同等に保つことの
できるカラー受像管を提供するものである。The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a color picture tube in which the shape of the inner shield reduces mislanding and maintains the waist magnetic shielding effect equivalent to that of an integral structure.
以下この考案を図について説明する。This idea will be explained below with reference to figures.
第１図は従来のカラー受像管の分解斜面図である。FIG. 1 is an exploded perspective view of a conventional color picture tube.
第１図において、１はパネル、２はシャドウマスク、３
はフレーム、４は磁気シーリド、５はファンネルである
。In Figure 1, 1 is a panel, 2 is a shadow mask, and 3
is a frame, 4 is a magnetic shield, and 5 is a funnel.
第２図は本考案になる磁気シールドの斜視図で、一体プ
レス加工のインナーシールド６に２０ｒｒｖｎ以下の切
欠き７を電子銃側よりフレーム３に向って１ヶ以上入れ
た例である。FIG. 2 is a perspective view of the magnetic shield according to the present invention, which is an example in which one or more notches 7 of 20 rrvn or less are made in the integrally pressed inner shield 6 from the electron gun side toward the frame 3.
前記切欠き７を入れることにより、一体構造とほぼ同等
のシールド効果、ビーム移動量で約５０％を得ることが
できる。By inserting the notch 7, it is possible to obtain a shielding effect almost equivalent to that of an integral structure and a beam movement amount of about 50%.
同様に第３図は２ヶ以上に分割されたシールド６の例で
、すきま８を２−以下に保てば同じシールド効果を得る
ことができる。Similarly, FIG. 3 shows an example of a shield 6 divided into two or more parts, and the same shielding effect can be obtained by keeping the gap 8 at 2- or less.
以上の説明が明らかな如く、本考案になるインナーシー
ルドを用いたカラーブラウン管によれば、磁気シールド
効果を低下させることなく、ミスランディングを除去で
きる。As is clear from the above explanation, the color cathode ray tube using the inner shield according to the present invention can eliminate mislanding without reducing the magnetic shielding effect.
