A cathode ray tube, especially a high-intensity cathode ray tube, increases the energy of an electron beam that strikes the fluorescent surface to obtain a reproduced optical image of high brightness, but a front panel coated with a fluorescent material, that is, glass. Since the panel has a low thermal conductivity, the temperature rise is large especially in the central portion of the panel where it is difficult to dissipate heat during continuous operation. Therefore, in the fluorescent body,
So-called temperature quenching occurs in which the brightness decreases as the temperature rises. This temperature extinction causes the white balance to be out of order because the degree of the phosphor of each color is different.

As a cathode ray tube in which such temperature quenching does not occur, for example, as in the cathode ray tube apparatus disclosed in Japanese Utility Model Publication No. 59-7731, a cooling liquid is sealed in contact with the front panel of the cathode ray tube. A liquid-cooled cathode ray tube device has been proposed which is designed to effectively dissipate the heat of the central portion of the front panel of the cathode ray tube by convection of the cooling liquid.

Both surfaces of the panel and the panels (2) and (3) facing it are liquid-tightly sealed, and thus surrounded by the metal frame (5) between the panels (2) and (3). A cooling liquid (7) such as ethylene glycol is enclosed in the liquid tight space. In the cathode ray tube device having such a configuration, when the temperature of the front panel (2) rises due to the high-energy electron beam impact during operation, the cooling liquid (7) warmed with this temperature rise has a specific gravity. Rises due to
Convection is generated in the cooling liquid, whereby heat is transferred toward the metal frame body (5), and heat is dissipated from this to cool the front panel (2).

According to the above-mentioned structure, due to the presence of the spacer piece (27), the space between the metal frame body (15) and the front panel (2) of the pipe body (1), and thus the adhesive resin (6) between them, is prevented. Since the thickness can be set to the required, ie, necessary and sufficient thickness d 1 , reliable sealing and sufficient expansion and contraction due to the temperature rise / fall of the cooling liquid (7) are expanded and contracted to achieve liquid tightness. Can be held.

And according to the present invention, a plurality of spacer pieces (27)
Between the inner peripheral flange portion (14) of the metal frame body (15) and the front panel (2) of the cathode ray tube body (1). These spacer pieces (27) are Frame-shaped part (26)
Since it is integrated with each other, it is not necessary to handle them individually, and the frame-shaped spacer member (28) having this frame-shaped portion (26) can be arranged only by being housed in the metal frame body (15). Further, since the member (28) has rigidity as a whole and can retain its shape at the time of molding, its handling becomes easy, and its arrangement can be automatically mechanized.

Further, in practice, for example, in a color cathode ray tube body (1), the front panel (2) has a color fluorescent surface formed on the inner surface thereof, and then a glass is formed at the front opening end of the funnel (10) of the body. Fritted by the frit (11),
Generally, since the frit (11) has a relatively low insulating property, the high voltage part in the cathode ray tube body (1) and the frame part (16) of the metal frame body (15) are directly positively connected through this. If it does, there is a risk that discharge will occur between the two. However, according to the configuration of the present invention, the insulating frame-shaped spacer member (28) is provided between the portion where the frit (11) is present and the metal frame-shaped (15).
Since such a frame-shaped portion (26) can be interposed, the occurrence of such discharge is avoided.
