Abstract

The present invention provides a deflection yoke in which a vertical and horizontal coil is wound and a ferrite core mounted on a coil separator in order to provide a deflection yoke in which damage to a display device is prevented from static electricity generated in a comapri. It is composed of a yoke clamp for coupling the tube and the yoke clamp is provided on both sides of the outer peripheral surface of the tube, the at least one bent end is comma-free to the tube by the yoke clamp.

Description

Deflection yoke

The present invention relates to a deflection yoke, and more particularly, to a deflection yoke in which an electric shock generated by static electricity is prevented.

In general, a large deflection yoke is provided with a coma free to compensate for misconvergence, and the coma free is installed near a yoke clamp that fixes the deflection yoke, and a voltage induced in the coma free is adjacent to the coma free. The yoke clamp is discharged (Spark) may cause an error in the display device equipped with the deflection yoke.

1A is a front view of a deflection yoke according to the prior art, and FIG. 1B is a plan view of FIG. 1A.

The deflection yoke according to the related art is a deflection yoke composed of a coil separator, a ferrite core, or the like, the yoke clamp 10 connecting the coil separator with a tube and the yoke clamp 10 adjacent to the yoke clamp 10. It consists of the comapri 12 provided in both sides of the outer peripheral surface of a tube.

The deflection yoke according to the related art according to the related art is configured as described above, in the deflection yoke 100 having a coil separator 14 having a ferrite core wound around vertical and horizontal coils. Is combed by the yoke clamp 10 so as to be mounted to the tube, and the comma prism 12 formed on both sides of the outer circumferential surface of the tube adjacent to the yoke clamp 10 to the tube is electrons emitted from the electron gun. By deflecting, the misconvergence is operated to be corrected.

However, when the current flows in the vertical coil wound around the ferrite core, the comapri 12 provided adjacent to the yoke clamp 10 is induced with a voltage, and thus the yoke clamp 10 is connected to the yoke clamp 10. Since the induced voltage is discharged, there is a problem in that the display device equipped with the deflection yoke configured as described above is damaged.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and a main object of the invention is to provide a deflection yoke in which damage to the screen device is prevented from static electricity generated in Comapri.

A feature of the present invention for achieving the above object is a deflection yoke composed of a ferrite core wound with vertical and horizontal coils and mounted on a coil separator, the yoke clamp for coupling the coil separator to a tube and adjacent to the yoke clamp. And provided on both sides of the outer circumferential surface of the tube, and at least one bent end is composed of a comma-free which is connected to the tube by the yoke clamp.

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

Figure 2 is a schematic diagram showing a deflection yoke according to the present invention, Figure 3a is a front view of the comapri, Figure 3b is a side view of the comapri.

The deflection yoke according to the present invention is a deflection yoke composed of a ferrite core 26 in which vertical and horizontal coils are wound and mounted to a coil separator 24, which connects the coil separator 24 to the tube 28. Comapri 22 which is provided on both sides of the outer circumferential surface of the tube adjacent to the yoke clamp 20 and the yoke clamp 20, and at least one bent end is connected to the tube 28 by the yoke clamp 20 It is composed of

The following describes the operating state of the deflection yoke according to the present invention configured as described above.

The deflection yoke is stably fixed by the yoke clamp 20 which connects the coil separator 24 configured as described above with the tube 28. As shown in FIGS. 3A and 3B, at least one bending The comapri 22 having the one end is chamfered by the yoke clamp 20 between the inside of the yoke clamp 20 and the outside of the tube 28.

As described above, the comapri 22 is connected between the inside of the yoke clamp 20 and the outside of the tube 28 and the voltage is induced by a current flowing in a vertical coil. Since the voltage induced through the yoke clamp 20 flows to the ground of the screen device, the spark is prevented instantaneously.

As described in detail above, the present invention has a great effect of stably operating the screen device because the comma free is struck with the yoke clamp so that the induced voltage is naturally discharged so as to prevent damage to the screen device from static electricity generated in the comapri. There is.

The present invention is not limited to the above embodiments, and it is apparent that many modifications are possible by those skilled in the art within the technical spirit of the present invention.
