Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cathode ray tube device and a method of manufacturing the same, and more particularly to a structure and method for positioning and fixing a deflection yoke on a funnel portion of a cathode ray tube.

[0002]

2. Description of the Related Art Generally, in a self-convergence type color cathode ray tube, an error in a mounting position of a deflection yoke in the tube axis direction with respect to the cathode ray tube affects color purity.
The mounting angle with respect to the tube axis affects convergence and raster strain. Therefore, when the deflection yoke is attached and fixed to the funnel portion of the cathode ray tube, high attachment accuracy is required.

A conventional structure and method for positioning and fixing the deflection yoke on the funnel portion of the cathode ray tube will be described with reference to FIGS. 7 to 9. FIG. 7 is a side sectional view showing an example of a conventional deflection yoke 6 (saddle-saddle type deflection yoke), and FIG. 8 is a perspective view showing a wedge-shaped adjusting member 7 for mounting a conventional deflection yoke. FIG. 9 is a side sectional view showing an example of a state in which the conventional deflection yoke 6 is attached to the cathode ray tube 14.

A conventional self-convergence type deflection yoke 6 shown in FIGS. 7 and 9 is a saddle type horizontal deflection coil 1, a separator 2, a saddle type vertical deflection coil 3.
It is composed of a core 4 and the like. The conventional cathode ray tube 14 shown in FIG. 9 is composed of a glass panel portion 10, a glass funnel portion 11, a neck portion 12, an electron gun 13 and the like. The deflection yoke 6 is finally fixed to the neck portion 12 of the cathode ray tube 14 by a fastening member 9, but the attachment position of the cathode ray tube 14 in the tube axis direction and the attachment angle with the tube axis are different from those of the funnel portion 11 and the deflection. It is determined by a wedge-shaped adjusting member 7 inserted between the yoke 6 and the front surface. Cathode ray tube 14 (funnel portion 11) of the deflection yoke 6
After the mounting position and angle with respect to is determined, the mounting adjustment member 7 is placed in the gap between the deflection yoke 6 and the funnel portion 11.
Are inserted at appropriate intervals and fixed with an adhesive 15.

By precisely adjusting and fixing the position of the deflection yoke as described above, good image reproduction of the cathode ray tube device can be obtained. Further, in order to facilitate precise posture adjustment and fixing of the deflection yoke, for example, in Japanese Patent Laid-Open No. 4-328226, a guide groove is formed in the separator 2, and a wedge-shaped adjusting member 7 is inserted into the guide groove. A method of performing positioning has been proposed. Further, in Japanese Patent Laid-Open No. 7-6713,
A method has been proposed in which a wedge-shaped adjusting member 7 is provided with a discharge port for the adhesive 15.
