ABSTRACT:
A cathode support, in an electron gun of a cathode ray tube comprising four lamellae (22, 24, 25, 30) which are connected together by means of an electrically insulating sealing glass (23). A first one of the lamella (22) engages a first electrode (10) of the electron gun. Second and third lamellae (24, 25) are situated substantially in one plane, are electrically-insulated from each other, and are cathode filament. The cathode shaft (33) is suspended from a fourth one of the lamellae (30). The cathode support is well suited for automated mass production.
