<p>A method of manufacturing an electron gun (6) having a sub-assembly (42) to interconnect the beaded unit (33) and the base (28) of the electron gun. This sub-assembly is manufactured by making a pattern of apertures (41) in a planar element (40), thereby forming a number of securing means (42). In the next step of the manufacturing process, portions of the securing means (42) are bent out of the plane of the planar element (40) and then connected to an insulating plate (55), thus forming the sub-assembly (54) of securing means (42) and insulating plate (55). This sub-assembly (42) is preferably provided with funnel-shaped apertures (57) to lead the electric leads of a number of the electrodes (20-24) of the electron gun (6) through the insulating plate (55). This allows an accurate and easy interconnection of leads and pins (29) of the base (28).</p> |
