Abstract
Disclosed is a deflection yoke to improve screen quality, including a coiling density adjustment groove formed along a vertical direction of a coil by way of increasing the coiling density at an arbitrary portion of the electric field at the internal side of the deflection coil. To this end, a winding frame is provided for winding coil around the deflection yoke, having a curvature of a designated shape at the center, in which the winding frame includes a wire position guide that projects as much as a designated width to a vertical direction of a coil to be wound around an arbitrary portion of the internal electric field for increasing a coiling density.
Claims4
A deflection yoke, comprising:
- a conical-shaped coil separator mounted with a front cover that bonds with a cathode-ray tube and a rear cover that bonds with the neck portion on the opposite side;
- a ferrite core for forming a magnetic field on the exterior of the coil separator;
- a deflection coil having windings and forming a magnetic field together with the ferrite core;
- and
- a coiling density adjustment groove, formed to face away from the cathode ray tube on the exterior of the coil crosswise to the windings, thereby increasing coiling density of an electric field inside the deflection coil and underlying the groove.
