PHN 9840 11 ABSTRACT: A cathode support in an electron gun of a cath- ode ray tube which comprises four substantially parallel lamellae which are connected together by means of an electrically insulating sealing glass, of which a first metal lamella engages a first electrode, for example, the anode of the electron gun, second and third lamellae are situated substantially in one plane and are insulated electrically from each other, to which lamella the cath- ode filament is connected electrically, and the cathode shaft is suspended from a fourth lamella. This is very suitable for automated mass production of cathode ray tubes, for example television camera tubes, and enables a shorter cathode ray tube.
