Description

Compensation piece insertion structure of deflection yoke {INSERTION STRUCTURE FOR COMPENSATION PLATE OF DEFLECTION YOKE}

The present invention relates to a correction piece insertion structure of a deflection yoke. More specifically, a correction piece for correcting a YH deflection characteristic of a deflection yoke can be inserted into a neck portion of a separator so that the adjustment width of the deflection yoke can be adjusted. It relates to a compensating piece insertion structure of a deflection yoke for widening.

In general, the deflection yoke is mounted on the outer circumference of the cathode ray tube to deflect the electron beam emitted from the electron gun of the cathode ray tube to realize an accurate image.

The deflection yoke precisely distinguishes between the vertical deflection coil for deflecting the electron beam emitted from the cathode ray tube in the vertical direction, the horizontal deflection coil for deflecting the electron beam in the horizontal direction, and the positions of the vertical deflection coil and the horizontal deflection coil. It consists of a separator that can be electrically insulated from each other.

At this time, the electron beam of R (Red), G (Green), B (Blue) emitted from the electron gun of the cathode ray tube is deflected at a predetermined angle by the deflection yoke and then passes through the through hole formed in the shadow mask, By sealing the light on each stripe mounted on the inner circumference and emitting light, a normal image is realized on the screen of the television.

Meanwhile, the horizontal deflection coils and the vertical deflection coils respectively mounted on the inner and outer circumferences of the separator perform a function of deflecting the electron beam emitted from the electron gun of the cathode ray tube at a predetermined angle, depending on the mounted state or the wound shape. In some cases, the deflection angle is shifted, resulting in reverse crossover and misconvergence, thereby failing to realize a normal image.

In such a case, misconvergence or the like is generally corrected using a correction piece made of an alloy such as nickel (Ni) and iron (Fe).

As shown in Fig. 1, the correction piece insertion structure of the deflection yoke according to the prior art is a correction piece insertion structure for correcting a horizontal deflection coil deflection characteristic (hereinafter referred to as "YH deflection characteristic") that appears on the Y-axis line of the screen. The support 11 is formed so as to support the side of the correction piece which is formed to protrude upwardly from the upper surface of the neck portion 10, and is formed to protrude vertically in the inward direction of the support 11 to the upper surface of the neck portion 11. It consists of the support piece 12 which forms the correction piece insertion space between and.

Here, the correction piece inserted and fixed on the upper surface of the neck portion 10 affects the magnetic field of the horizontal deflection coil to correct the YH deflection characteristic due to misconvergence.

However, since the correction piece insertion structure of the deflection yoke according to the prior art having the above-described configuration can only be mounted on the neck portion for correction of the YH deflection characteristic of the deflection yoke, the correction for the YH deflection characteristic is If it is weak, there was a problem that it is difficult to control more than the YH deflection characteristics, thereby resulting in the deterioration of the characteristics of the yoke.

The present invention has been proposed to solve the above problems, and its purpose is to allow the insertion and mounting of a correction piece for correcting the YH deflection characteristic of the deflection yoke on the neck portion of the separator as well. By allowing easy insertion, the adjustment range for the YH deflection characteristics of the deflection yoke can be widened to improve the deflection characteristics of the deflection yoke as well as to provide the operator with the convenience of assembling the correction piece. It is to provide a correction piece insertion structure of.
