た赤・緑・青の蛍光膜２に衝突し発光する原理である。As schematically shown in FIGS. 3 and 4, in a color cathode ray tube, electrons emitted from an electron gun 13 pass through a shadow mask 7, and red, green, and blue fluorescent films 2 are coated regularly on the inner surface of the panel in advance. This is the principle behind the collision of light and light.

あった。In order to operate, a high voltage of about 25 KV is supplied to the inside surface of the panel from an external power source through the anode button 11 of the funnel. The supply route is that electricity is applied to the interior graphite 12 on the inner surface of the funnel from the anode button 11, and from the interior graphite 12, voltage is supplied to the panel stud pin 4 via the contact spring 10 welded to the shadow mask structure, which is a conductor, and the stud pin 4, conductive graphite 6 is applied with a brush between the aluminum vapor deposited film 3 deposited on the fluorescent film, and a high voltage is supplied to the entire inner surface of the panel. In this way, the conduction between the star, rad pin, and the aluminum vapor-deposited film is done manually, so there are problems such as poor conductivity due to forgetting to apply or short graphite dimensions, and peeling off due to thicker graphite film. In addition, if the aluminum vapor-deposited film is vapor-deposited on the stud pins, the aluminum will be missing when attaching and detaching the support piece that holds the mask structure. had to be avoided.

からの高電圧の供給を容易にしたことを特徴とする。In the panel tank body of the present invention, stud pins embedded in the panel are provided with conductive metal rod-shaped leads.
A feature is that an aluminum vapor-deposited film is formed on the rod-shaped lead, making it easy to supply high voltage from the stud pin.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

４より可能となる。2(a) and (b) are a sectional view and a front view of an embodiment in which the stud pin of the present invention is embedded in a panel.The rod-shaped lead 5 is located 180 degrees opposite the panel sealing surface 14, and A portion of the rod-shaped lead 5 is exposed from the glass surface of the panel 1.The length of the rod-shaped lead 5 is such that it can be polymerized with the aluminum evaporation film 3.Thereby, conduction with the aluminum evaporation film 3 is established. This is possible from the stud pin 4 via the rod-shaped lead 5.

が可能となる。As explained above, the present invention enables electrical conduction between the aluminum evaporated film and the stud pin, which is necessary for operating a color cathode ray tube, by providing a conductive metal rod-shaped lead on the stud pin, which was previously done manually. Problems such as poor conductivity due to the small dimensions of the conductive graphite coating film and peeling due to the large thickness of the coating film can be solved, and it is possible to save labor in the process.
