Cathode-ray tube having multiplate cathode unit

摘要

A cathode-ray tube, such as a camera tube or a display tube, having an electron gun with a cathode unit including a cathode shank (30) suspended coaxially in an aperture in an assembly plate (38) and extending perpendicularly to the longitudinal axis of the electron gun. The cathode unit includes a metal supporting plate (41) which is accurately positioned with respect to the assembly plate (38). The assembly plate (38) and the supporting plate (41) each have two apertures through which supporting pins (44) for electrical connection lugs (32) extend. Glass plugs (43) connect the assembly plate (38), the supporting pins (44) and the supporting plate (41) together.
