Abstract
An electron beam deflection structure for a high frequency cathode-ray tube incorporates a meanderline slow wave circuit that is supported directly by the same glass rods used to support other portions of the CRT's beam forming and deflection system. To accomplish this, elongate loops that serially interconnect a plurality of deflection plate segments are bent away from the plane of the segments (and the beam axis) and joined by integral support strips to the rods. The elimination of a separate support structure for the deflectors greatly reduces manufacturing costs.
Claims11
A deflection structure for a cathode-ray tube having means therein for producing a beam of electrons, said structure comprising
- a serpentine meanderline of conductive material along which deflection signals travel, said meanderline being formed by a plurality of plate segments disposed in spaced edge-to-edge relation in a row extending generally along the path of said beam and serially interconnected generally U-shaped strips of substantially narrower width, said strips extending angularly away from the plane of each segment, and
- means supporting the meanderline in said tube, said means comprising a pair of insulating rods extending in the direction of said path, one along each side of said row, and means for securing said strips to said rods.

- means supporting said meanderlines in spaced relation on opposite sides of said path, said means comprising for each meanderline a pair of insulating rods extending in the direction of said path, one along each side of the row of plate segments in said line, and means for securing the strips of each line to the insulating rods for said line.
