The invention relates to a saddle-saddle type deflection yoke, and more particularly to the cross talk by allowing the vertical deflection coil mounted on the outside of the coil separator to rotate in the same manner as the ferrite core. The invention relates to a saddle-saddle deflection yoke that facilitates adjustment and improves workability.

Generally, the deflection yoke used in a cathode ray tube (CRT) such as a TV receiver or a monitor has various types such as a saddle-toroidal type and a saddle-saddle, and the saddle-troidal deflection yoke is a coil separator. A horizontal deflection coil wound in a saddle shape is mounted on the inner side thereof, and a ferrite core wound in a troidal shape on the outer side of the vertical deflection coil is assembled by the core clamp.

However, the horizontal and vertical deflection coils of the saddle-troid type deflection yoke form magnetic fields as a sawtooth pulse is applied to deflect the R (red), G (green), and B (blue) electron beams emitted from the electron gun. Although the dice of the phase are determined, since the ultra-low frequency (about 10KHz ~ 300KHz) leakage magnetic field that is likely to adversely affect the human body is generated outside the cathode ray tube, various means are used to prevent the leakage magnetic field.

Therefore, in recent years, not only can the leakage magnetic field be prevented more efficiently than the saddle-troidal deflection yoke, but there is a tendency to increase the use of the saddle-saddle deflection yoke which has a good deflection sensitivity and the design can be easily changed during manufacturing.

A conventional saddle-saddle deflection yoke 1 is a pair of coils wound around the inside and outside of a coil separator 4 consisting of a neck portion 2 and a screen portion 3, as shown in FIG. A horizontal deflection coil (not shown) and a vertical deflection coil 5 are mounted, and between the vertical deflection coils 5, a spacer 6 having a predetermined width manufactured in a rectangular shape is installed to maintain a mutual gap. The ferrite core 7 is assembled with the core clamp 8 on the outside of the vertical deflection coil 5, and is applied by the magnetic field generated in the horizontal deflection coil as the sawtooth pulse is applied to the horizontal and vertical deflection coils 5. Since the voltage is induced to the vertical deflection coil 5, it is necessary to adjust the crosstalk to minimize the mutual influence of the horizontal and vertical deflection coil 5 by minimizing this.

At this time, the adjustment of the crosstalk is a vertical deflection coil (5) exposed to the outside of the ferrite core (7) by aligning the center of the tilt (Tilt) generated by the dispersion of the coil wound on the horizontal and vertical deflection coil (5) It is necessary to rotate by holding the coil portion of the coil, but this is because the vertical deflection coil (5) and the ferrite core (7) are not completely fixed on the coil separator (4) when the vertical deflection coil (5) rotates There is a troublesome problem in adjusting the crosstalk such that the core 7 is rotated separately.

The object of the present invention is to solve the above problems, and an object of the present invention is to flow in the same way as a ferrite core in a window portion of a vertical deflection coil wound and mounted in a saddle shape on the outside of the coil separator. By providing means, when adjusting the crosstalk of horizontal and vertical deflection coils, the ferrite core mounted on the outside of the vertical deflection coil is held, and the vertical deflection coils are rotated in the same direction when rotated left and right. This makes it easier to provide a saddle-saddle deflection yoke that can improve product productivity.

A feature of this invention for achieving the above object is a pair of horizontal and vertical deflection coils wound in a saddle shape on the inside and the outside of a coil separator consisting of a neck portion and a screen portion, and on the outside of the vertical deflection coil. In a saddle-saddle deflection yoke in which a ferrite core is assembled with a core clamp, an interlocking means is installed between the window portion of the vertical deflection coil and the ferrite core to adjust the cross torque while rotating the vertical deflection coil in the same manner as the ferrite core. There is a saddle-bird deflection yoke that makes it possible.

Hereinafter, the saddle-saddle deflection yoke according to the present invention will be described in detail with reference to the accompanying drawings.

2a, b to 4a, b is a view showing an embodiment for explaining the saddle-saddle deflection yoke according to the present invention, first, the saddle-saddle deflection yoke 11 is the neck portion 12 and the screen A pair of horizontal deflection coils (not shown) and vertical deflection coils 15, which are wound in a saddle shape, are mounted inside and outside the coil separator 14 formed of a portion 13, between the vertical deflection coils 15. The spacers 16 are formed in a rectangular shape and are spaced apart from each other, and the ferrites 17 having the coupling grooves 17a on the outer side of the vertical deflection coil 15 are provided as core clamps 18. Are assembled.

In addition, a flow means is installed between the window portion 15a of the vertical deflection coil 15 and the ferrite core 17, and the flow means has a coupling piece 19a having a predetermined length on the outer circumferential surface of the interlocking member 19. And a coupling piece 19a of the interlocking member 19 is fitted with a coupling groove 17a formed in the ferrite core 17 so that the ferrite core 17 and the vertical deflection coil 15 are rotated in the same manner. .

On the other hand, as shown in Figure 4a, b as another embodiment of the interlocking means, at least two or more projections (20a) are formed in the outer peripheral surface of the interlocking member 20 in a circular or rectangular shape, the interlocking member 20 is It is installed in the window portion 15a of the vertical deflection coil 15 to be in close contact with the inner surface of the ferrite core 17.

The saddle-saddle deflection yoke 11 of this invention, as described above, rotates left and right by holding the outer circumferential surface of the ferrite core 17 to adjust the cross torque of the horizontal deflection coil and the vertical deflection coil 15. When the coupling piece 19a of the interlocking member 19 provided in the window portion 15a of the vertical deflection coil 15 is fitted with the coupling groove 17a of the ferrite core 17, the vertical deflection coil 15 As one side is supported by the interlocking member 19, the vertical deflection coil 15 is also rotated in the same manner as the ferrite core 17 is rotated, thereby making it easy to adjust the cross torque.

On the other hand, as shown in Figure 4a, b as another embodiment of the interlocking means, the interlocking member 20 having at least two projections (20a) formed in a circular or square on the outer peripheral surface of the window portion of the vertical deflection coil 15 ( 15a) is to be in close contact with the inner surface of the ferrite core 17, so as to rotate the vertical deflection coil 15 in accordance with the rotation of the ferrite core 17 to adjust the cross torque, the interlocking member 20 As the number of protrusions 20a is increased to a plurality, the adhesion force with the ferrite core 17 is increased, and the coupling groove 17a of the ferrite core 17 is formed in the interlocking member 20 in which the protrusions 20a are formed as described above. ) Does not need to be formed.
