Method of manufacturing an electron gun, electron gun, display device with such an electron gun, and sub-assembly for use in such an electron gun

摘要

A method of manufacturing an electron gun having a sub-assembly to interconnect the beaded unit and the base of the electron gun. This sub-assembly is manufactured by making a pattern of apertures in a planar element, thereby forming a number of securing elements. In the next step, portions of the securing elements are bent out of the plane of the planar element and then connected to an insulating plate, thus forming the sub-assembly of securing elements and insulating plate. This sub-assembly is preferably provided with funnel-shaped apertures to lead the electric leads of a number of gun electrodes through the insulating plate. This allows an accurate and easy interconnection of the electric leads and the pins of the base.
