摘要： Disclosed is a directly heated cathode assembly for a cathode ray tube electron gun, comprisingfirst and second conductive support members disposed to face each other via an insulating base plate,a ribbon filament stretched between the first and second conductive support members such that the width direction thereof is parallel with the axis of the electron gun,a cathode consisting of a metal substrate covered with an electron emissive coating and a support portion integral with or fixed to the metal substrate, the coating layer extending in a direction perpendicular to the axis of the electron gun and the cathode being mounted to the central portion of the filament, andat least one spring member whose free end resiliently abuts against the filament in a direction perpendicular to a plane including the axis of the electron gun.
