ABSTRACT:
An integrated grid (G1/G2) assembly having enhanced mechanical strength and rigidity is provided for use in an electron gun assembly of a cathode ray tube (CRT). In the integrated grid assembly, the first and second grids (35 and 40, respectively) are fixed in relationship to one another, both axially and radially, by means of an insulating element (50) and a collar element (55). Brazed joints are preferably provided at the interface of the insulating element (50) with the second grid (40) and the collar element (55) to enhance the mechanical strength and rigidity of the assembly. An integrated grid (G1/G2)/anode assembly may be provided by mounting anode assembly (45) fixedly with respect to second grid (40) by means of second insulating element (60) and second collar element (65). Methods for assembling the integrated grid assemblies are also disclosed.
