Abstract
A deflection yoke for CRTs, designed to easily correct a misconvergence in a vertical direction of a frame without being rotated during a frame correction step, is disclosed. The deflection yoke has a coil separator composed of a screen part, a rear cover part and a neck part. A plurality of horizontal and vertical deflection coils are set on the internal and external surfaces of the coil separator and generate horizontal and vertical deflection magnetic fields. A correction means is provided on the rear cover part of the coil separator and corrects the vertical magnetic field in addition to frame dispersion. A position adjusting means is provided at a position between the rear cover part and the correction means and holds the correction means on the rear cover part while allowing the position of the correction means relative to the rear cover part to be finely and precisely adjustable. This deflection yoke precisely and stably corrects both the frame dispersion and the vertical magnetic field. In the correction means, two correction pieces are connected together into a single structure by a guider. This guider also almost completely prevents the correction pieces from being undesirably displaced on or removed from the rear cover part, thus improving the operational reliability of the deflection yoke.
