The present invention relates to a saddle-saddle type deflection yoke, and more specifically, a spacer is installed between the vertical deflection coil and the ferrite core mounted on the outside of the coil separator so that the mutual gap between the vertical deflection coils is fixed. This invention relates to a spacer of a saddle-saddle deflection yoke, which can be maintained at the same time and at the same time prevent a leakage magnetic field.

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 has a neck portion. A horizontal deflection coil wound in a saddle shape is mounted inside the coil separator including a screen portion, and a ferrite core in which a vertical deflection coil is wound in a troidal shape 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 R (red), G (green), and B (blue) electron beams emitted from the electron gun. Although the dice are determined on the outside of the cathode ray tube, various means have been used to prevent the leakage magnetic fields because they generate an ultra-low frequency (about 10 Hz to 300 Hz) leakage magnetic field that is likely to adversely affect the human body. Is in.

Therefore, in recent years, not only can the leakage magnetic field be prevented more effectively than the saddle-troidal deflection yoke, but also the use of the saddle-saddle deflection yoke, which has a good deflection sensitivity of the electron beam and is easy to change the design in manufacturing, have.

The conventional saddle-saddle deflection yoke 1 is wound in a saddle shape on the inside and outside of the coil separator 4 composed of the neck portion 2 and the screen portion 3, as shown in FIG. A pair of horizontal deflection coils (not shown) and horizontal deflection coils 5 are mounted, and between the vertical deflection coils 5, a space 6 is formed in a rectangular shape to maintain a mutual gap. The ferrite core 7 is assembled to the core clamp 8 on the outside of the vertical deflection coil 5, and a magnetic field generated in the horizontal deflection coil as the sawtooth pulse is applied to the horizontal and vertical deflection coils 5. By the voltage is maintained by the vertical deflection coil (5), to minimize the cross talk (Cross Talk) to minimize the mutual influence of the horizontal and vertical deflection coil (5).

At this time, the adjustment of the cross-talk is a vertical deflection coil (5) exposed to the outside of the ferrite core (7) by aligning the center of the tilt (Tite) generated by the dispersion of the coil wound on the horizontal and vertical deflection coil (5) Hold the coil of the coil and rotate it in the left and right directions. However, since the vertical deflection coil 5 and the ferrite core 7 are not completely fixed on the coil separator 4, the vertical deflection coil 5 During the rotation of the spacer 6 is pushed upward and downward, it is impossible to maintain a constant height.

Therefore, the unevenness of the vertical deflection coil 5 is caused by the flow of the spacer 6, which not only makes the assembly work inconvenient, but also interferes with the adjustment of the cross torque, and the saddle-saddle deflection yoke 1 Although it is possible to prevent the leakage magnetic field more than the saddle-troyed deflection yoke, there was an unsatisfactory problem.

The object of the present invention is to solve the above problems, and an object of the present invention is to provide a magnetic field formed in the horizontal and vertical deflection coils by installing a pair of spacers between the vertical deflection coil and the ferrite core mounted on the outer side of the coil separator. The leakage magnetic field generated from the product can be prevented more efficiently, and the reliability of the product is not only improved, but the installation position of the spacer is kept constant, thereby preventing the unbalance of the vertical deflection coil. To provide a spacer of a saddle-saddle deflection yoke.

A feature of the present 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, a pair of spacers are provided between the vertical deflection coil and the ferrite core to prevent a leakage magnetic field, and the spacer has support pieces on the upper and lower sides of the body, respectively. It is formed in the spacer of the saddle-saddle deflection yoke, which is formed at both ends and the divided pieces are each bent to maintain the vertical deflection coil at a constant interval.

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

2 and 3 show an embodiment for explaining the spacer of the saddle-saddle deflection yoke according to the present invention. First, the saddle-saddle deflection yoke 11 has a neck portion 12 and a screen portion ( 13, a pair of horizontal deflection coils (not shown) wound in a saddle shape is mounted inside the coil separator 14, and a pair of vertical deflection coils 15 wound in a saddle shape are mounted to the outside. .

In addition, a pair of spacers 16 are disposed outside the vertical deflection coil 15, and the spacers 16 are formed in the same curved shape as the coil separator 14, and the spacers 16 are formed. The support body 18a of the same square shape as the neck part 12 is formed in the upper side of the body 17, and the circular support piece 18b is formed in the same shape as the screen part 13 in the lower side.

In addition, the divided pieces 19a and 19b are bent at both ends of the body 17 of the spacer 16 so that both sides of the vertical deflection coil 15 can be held and mounted at a predetermined interval. A pair of ferrite cores 20 are assembled to the outer side of the spacer 16 by the core clamp 21.

The saddle-saddle deflection yoke 11 of this design, as described above, is supported by a central portion of the vertical deflection coil 15 wound in a saddle shape wrapped around the inner circumferential surface of the body 17 of the spacer 16. The upper side of the vertical deflection coil 15 is supported on the upper surface of the support piece 18a of the body 17 and the lower side is firmly mounted on the lower surface of the support piece 18b of the body 17.

In addition, since the divided pieces 19a and 19b bent on both sides of the body 17 of the spacer 16 are regulated by mutual gaps of the vertical deflection coils 15, the mounting position is precisely maintained, thereby facilitating assembly work. When adjusting the cross torque of the horizontal and vertical deflection coils 15 by maintaining a constant height while preventing the flow of the spacer 16, the unbalance of the vertical deflection coil 15 is prevented and the cross torque is easily adjusted.

In addition, after mounting the saddle-saddle deflection yoke 11 to a cathode ray tube such as a TV receiver or a monitor, when a sawtooth pulse is applied to the horizontal and vertical deflection coils 15, a magnetic field is formed and R is emitted from the electron gun. And deflecting the electron beams of G and B to determine the dice on the screen. At this time, the leakage magnetic field generated while flowing into and out of the coil separator 14 is efficiently carried out by the spacer 16 and the ferrite core 20. Is prevented.

As described above, this design provides a pair of spacers between the vertical deflection coil and the ferrite core mounted on the outer side of the coil separator to prevent leakage magnetic field more efficiently and to prevent the unbalance of the vertical deflection coil to adjust the cross torque. It is a useful design that can improve the reliability and productivity of the product by facilitating.
