Abstract
A deflection yoke for a cathode ray tube comprises a funnel shaped separator means 1a, 1b having a cylindrical neck portion 3 where a magnetic ring is attached. The magnetic ring is engaged with upward holding portions 33a, 33b and with downward holding portions 32a, 32b, which hold such magnetic ring. Root portions 33a3 and 33b3 of the downward holding portions 32a and 32b are substantially inflexible, where the inner circumference of the magnetic ring substantially contacts the root portions 33a3 and 33b3, and the root portions 33a3 and 33b3 restrict the position of magnetic ring from being disengaged from the protrusions 33a1 and 33b1 when the downward holding portions 33a and 33b are forced to disengage the magnetic ring.
Claims4
A deflection yoke for a cathode ray tube comprising:
