    • A deflection yoke is provided for a CRT, which includes horizontal and vertical deflection coils that deflect electron beams emitted from an electron gun in a horizontal or vertical direction, a ferrite core that reduces a loss of magnetic force caused by the horizontal and vertical deflection coils thereby enhancing magnetic efficiency, and a holder that holds the horizontal deflection coils, the vertical deflection coils, and the ferrite core at required positions, and provides insulation between the horizontal deflection coils and the vertical deflection coils. The horizontal and/or vertical deflection coils have a substantially rectangular shape on a screen side, and the ferrite core is circular or elliptical. This reduces material costs and reduces convergence and distortion errors, because a dimensional distribution of an inside surface area of the ferrite core is reduced with respect to related art deflection yokes, and polishing of an inside surface becomes easier. This significantly improves production yield and the dimensional distribution of the ferrite core.
    • 为CRT提供偏转线圈,其包括水平和垂直偏转线圈,其偏转电子枪在水平或垂直方向上发射的电子束,铁氧体磁心减少由水平和垂直偏转线圈引起的磁力损失 从而提高磁效率,以及将水平偏转线圈,垂直偏转线圈和铁氧体磁心保持在所需位置的保持器,并且在水平偏转线圈和垂直偏转线圈之间提供绝缘。 水平和/或垂直偏转线圈在屏幕侧具有基本矩形的形状,铁氧体磁芯是圆形或椭圆形。 由于相对于现有技术的偏转线圈,铁氧体磁芯的内表面积的尺寸分布减小,因此内部面的研磨变得容易,因此能够降低材料成本,降低会聚和失真误差。 这显着提高了铁素体芯的生产率和尺寸分布。

    • A device for simply and precisely fixing a deflection yoke to a Braun tube in such a manner that it does not permanently affix the yoke to the Braun tube but permits the location and fixing angle of the yoke with respect to the Braun tube be easily changed as required. The device includes a holder, coupled to a separator, and a plurality of wedge type cams rotatably mounted on the holder. The holder is provided with a plurality of mounts for rotatably supporting the wedge type cams respectively, a plurality of releasable fixing members for fixing the cams at their adjusted angles, and connection bands extending between the mounts for connecting the mounts together. The wedge type cams not only adjust the yoke fixing angle for compensation of mis-alignment of electron gun but also releasably affix the deflection yoke to the Braun tube. In another embodiment, the wedge type cams may be substituted by pulley type cams which are rotatably mounted on the holder.
    • 一种用于将偏转线圈简单且精确地固定到布朗管的装置,使得它不将轭固定地固定到布朗管,而允许轭相对于布劳恩管的位置和固定角度容易地改变为 需要。 该装置包括联接到分离器的保持器和可旋转地安装在保持器上的多个楔形凸轮。 保持器设置有用于分别可旋转地支撑楔形凸轮的多个安装件,用于以调节的角度固定凸轮的多个可释放的固定构件以及在安装件之间延伸的用于将安装件连接在一起的连接带。 楔形凸轮不仅调整轭固定角度以补偿电子枪的错误对准,而且还可以将偏转线圈可拆卸地固定到布朗管。 在另一个实施例中,楔形凸轮可以被可旋转地安装在支架上的滑轮型凸轮代替。
