    • A shadow mask spring for a color cathode ray tube having a generally rectangular shadow mask structure including a shadow mask and a support frame for holding the shadow mask. Shadow mask springs serve for holding the support frame inside a panel having a phosphor screen adjacent thereto and engage with panel pins for holding the shadow mask structure. Each of the shadow mask springs includes L-shaped base plate and a joined plate secured to one end of the base plate. The base plate has a phosphor screen side metal portion and an electron gun side metal portion with the phosphor screen side metal portion having a smaller thermal expansion coefficient than that of the electron gun side metal portion. An other end of the base plate is secured to a side of the support frame. The joined plate is engageable with a panel pin and the secured portion of the one end of the base plate and the joined plate is located at a position closer to the phosphor screen than the secured portion of the other end of the base plate and the support frame.
    • 一种用于彩色阴极射线管的荫罩弹簧,其具有包括荫罩和用于保持荫罩的支撑框架的大致矩形的荫罩结构。 荫罩弹簧用于将支撑框架保持在具有与其相邻的荧光屏的面板内,并与用于保持荫罩结构的面板销接合。 每个荫罩弹簧包括L形基板和固定到基板的一端的接合板。 基板具有荧光屏侧金属部分和电子枪侧金属部分,荧光屏侧金属部分的热膨胀系数比电子枪侧金属部分的热膨胀系数小。 基板的另一端固定到支撑框架的一侧。 接合板可与面板销接合,并且基板的一端的固定部分和接合板位于比基板的另一端的固定部分更靠近荧光屏的位置,并且支撑件 帧。
