The figure shows a cross-sectional view of a picture tube with an extra getter installed, and Figure 2 shows a detailed partial side cross-sectional view of the structure of the getter installation.
In the figure, 1 is a funnel part of a cathode ray tube with a conductive film 2 formed on its inner wall surface, and 3 is an anode button terminal embedded in this funnel part IVc.
As shown in the plan view and cross-sectional view, a locking portion 4 having an insertion hole 5 formed integrally with the terminal 3 protrudes into the inside of the funnel portion 1 . Reference numeral 6 denotes a getter supporting metal plate with a getter 7 attached to its tip (left end in FIG. 2), and this metal plate 6 is a VCC all-metal plate 6 as shown in FIG.
The tongue piece 9 is completely formed by cutting and raising the tongue piece 8 integrally with the notch step part 8 in the middle. When the getter supporting metal plate 6 is inserted into the insertion hole 5 of the locking part 4, the notch step part 8 is engaged with one end surface of the locking part 4, and the tongue piece 9 is engaged with the other end surface. Ru. That is, the getter supporting metal plate 6 is fixed by sandwiching the locking part 4 between the cutout step part 8 and the tongue piece 9.
