摘要：
A cathode ray tube is provided with a deflection unit. The yoke is secured to a flange of a coil holder by means of connecting elements. These connecting elements are flexible in the radial direction so that differences in thermal expansion between the yoke and the rest of the deflection unit are compensated in a flexible manner. By virtue thereof, movement of the yoke relative to the coils, which leads to an irreversible change of the deflection fields, is precluded or is at least less likely.
