Abstract

PURPOSE:To uniform the friction resistance and the fastening force of the full surface of band plates by providing a crossing member in which a specific scope of width at the positions symmetric to the rising fastening parts of outer circular band plates is reduced, and forming inner circular band plates sliding to the inner circumferential side through the crossing member. CONSTITUTION:The specific surfaces of the left and the right band plates 11 at the positions symmectric to the fastening members 12 of outer circular band plates 11 having the rising fastening parts 12 are reduced to form width reduction parts 13. While the width reduction parts 13 are crossed staggered each other, inner circular band plates 14 sliding to the inner circumferential surface of the band plates 11 are formed endless through the width reduction parts 13. The band plates 14 are formed in a superposing part at the openings of the band plates 11, and a spot welding is applied so as to make the inner circumferential surface almost in a round condition. As a result, by regulating the contact of the fastening members 12 with a screw, the diameter of the inner circular band plates is reduced together with the reduction of the diameter of the outer circular band plates, and an even friction resistance and fastening force can be obtained over the full circumference of the band plates.

2. Description of the Related Art The deflection yoke is fixed to a CRT by using a CRT cone 1 as generally shown in FIG.
The protrusion 2 that is formed by projecting to the back side of the device has slits formed on the neck portion 2 containing the electron gun and having a separable separator 4 having a core 5 wound with a coil, and is outwardly symmetrically positioned. At the tail portion 4a forming the portion 4b, both ends of the band plate 6 formed in an end ring shape are bent outward to form a pair of confronting tightening portions 7 and 8, and the tightening screw 9 is tightened on the tightening portions 7 and 8. By using a tightening band in which the tightening portions 7 and 8 are adjusted to come into contact with and separate from each other so that the diameters of the strips can be made different from each other, and the fitting hole 6b of the band is used to project the tail portion 4a. It is used that it is tightened and fixed by a tightening screw 9 in a state of being fitted to the portion 4b.

However, in the case of using the above-mentioned conventional tightening neck band, the band plate 6 formed in an annular shape was made to stand up toward the outside formed at both ends. A gap is created between the pair of tightening portions 7 and 8, and as a result, not only the tightening force of the gap portion cannot be obtained, but also the respective rising angle portions of the tightening portions 7 and 8 enter inside during tightening, and However, there is a problem in that the position of the deflection yoke is displaced and the screen focus is distorted.

Further, since the contact area of the inner peripheral surface of the tightening band with respect to the tail portion of the separator is small, not only is the deflection yoke not sufficiently fixed, but also a larger tightening torque is required for tightening, and therefore the above-mentioned rising is caused. Excessive tightening stress is locally applied only to a specific portion in the circumferential direction including the corners, and the neck portion containing the electron gun is often broken. In addition, this tendency is becoming more remarkable in connection with the tendency of expansion of the deflection yoke accompanying the increase in size of the television.

When the pair of rising tightening portions provided at the ends of the outer ring band plate are adjusted to be brought into contact with or separated from each other by the screws, the diameter of the outer ring band plate is correspondingly reduced, and the inner ring band plate is internally crossed through the intersection. The diameter of the annulus is gradually reduced or expanded along the inner peripheral surface of the outer annulus and in the opposite direction to the outer annulus, and the diameter is gradually reduced or expanded. The diameter of the strip is changed without creating a gap to generate a uniform tightening torque over the entire peripheral surface.

Further, by joining the other ends of the annular body to each other and integrally joining them together, the two annular bodies can be integrated with each other, thereby creating a gap between the both ends of the outer ring strip. Therefore, it is possible to manufacture the deflection yoke fixing neck band that produces a uniform tightening torque over the entire peripheral surface by varying the diameter of the strip plate.

Finally, the open ends of the two annular bodies R, R on the side not having the tightening portion 12 (the inner ring strip 14) are joined together so as to be integral with each other. As a joining method in this case, as shown in FIG. 1, one end is expanded to the outer peripheral side by the plate pressure, and the other end is formed by both ends.

As described above, according to the present invention, the structure of the tightening band for fixing the deflection yoke is configured so that the fixed range of symmetrical positions with the pair of left and right rising tightening portions of the outer ring strip provided with the rising tightening portions is approximately half width. The left and right strips are reduced in width so as to intersect each other in a staggered manner, and an inner ring strip that slidably contacts the inner circumferential side of the outer ring strip is formed endlessly through the intersecting portion. For this reason, there is no gap between the pair of tightening parts that are formed outward at the ends of the end plate formed into a tubular shape, and the diameter of the outer ring band plate is reduced. Since the inner diameter of the inner ring band plate is indirectly reduced and expanded as the size increases, local tightening stress does not act, and therefore the entire circumference of the band plate is tightened by tightening the tightening screws. Uniform friction resistance and tightening force It is possible to obtain.

1. A deflection yoke fixing in which a pair of rising tightening portions opposed to both ends of an annular band plate partially opened are adjusted to be brought into contact with and separated from each other by screws to change an inner diameter. A tightening band for use in which the left and right band plates are staggered by reducing a certain range of a symmetrical position with a pair of left and right rising tightening parts of an outer ring band plate provided with rising tightening parts to approximately a half width. A neckband for fixing a deflection yoke in a CRT, characterized in that an inner ring band plate is formed in an endless shape so as to intersect with the outer ring band plate and slidably contact the inner ring side of the outer ring band plate through the crossing portion.

2. A set of two annular bodies in which a fixed interval in an intermediate portion of a band plate formed in an end ring shape is reduced to about a half width, and only one end is erected outward to form a tightening portion. The step of molding, and the side half where the tightening portions are erected so that the tightening portions of the respective annular bodies are opposed to each other on the outside, and the side not having the tightening portions is on the inside, and the width-reducing portion is positioned so as to be positioned relative to each other. 2. A method of manufacturing a neck band for fixing a deflection yoke in a CRT, comprising the steps of assembling by crossing each other in a staggered manner, and the step of abutting the other ends of the respective annular bodies and integrally joining them together.
