HOLDER STRUCTURE OF CHARACTERISTIC IMPROVEMENT FOR CONVERGENCE IN A DEFLECTION YOKE}

The present invention relates to a holder structure of a deflection yoke, and in particular, to provide a trapezoidal holder structure that combines a structure for inserting iron pieces and supporting the upper side of a core, thereby converging a deflection yoke applied to a TV (or a large color TV) or a monitor. The present invention relates to a holder structure for improving convergence characteristics of a deflection yoke to improve XH unbalance among characteristics.

In general, when assembling a vertical deflection coil in a deflection yoke applied to a large color TV or monitor, the center of the magnetic field of the vertical deflection coil does not coincide with the magnetic field center of the horizontal deflection coil. Unbalance phenomenon occurs.

That is, as shown in FIG. 1 and FIG. 2, the R (red) and B (blue) beams of the vertical components of the screen do not appear in the same direction or in the same direction, but are inverted or unbalanced XH unbalanced phenomenon (FIG. 1 is R WIDE of the beam, and FIG. 2 shows NARROW of the R beam.

3 and 4, the slitting holder structure of the conventional deflection yoke has a horizontal upper support protrusion 1 in the horizontal form and a core left and right flow prevention protrusion 2 in the absence of flow. The upper side of the core was fixed by installing so as to face each other.

However, the holder structure of the conventional deflection yoke as described above has not only elasticity for flowing the core upper support protrusion 1 according to the height difference of the core, but also due to left and right deflection when assembling the vertical deflection coil 3 to the holder. Since there is a structure that can not insert a correction iron for improving the screen characteristics (XH unbalance) generated, there is an inconvenience to use a different correction to improve the XH unbalance.

Accordingly, the present invention provides a vertical deflection coil and a trapezoidal holder structure in which a core upper support protrusion having a predetermined inclination angle and a correction iron piece insertion unit are integrated to have elasticity according to the height of the core in order to solve the conventional problems as described above. It is the purpose to easily improve the XH unbalance generated when assembling the vertical deflection coil among the convergence characteristics of the deflection yoke applied to a TV (or large color TV) or a monitor by easily inserting and removing a correction iron piece. .

As shown in Figs. 5 to 7, in a horizontal configuration, in the holder structure of the deflection yoke including the core left and right flow preventing projections 2 for preventing the left and right flow of the core and using the screen characteristics correction iron piece 10, ,

While facing the core left and right flow preventing projections 2 to support the upper side of the core while the correction iron piece 10 is inserted to provide a trapezoidal fixing member 20 to improve the XH unbalance of the screen,

On both sides of the fixing member 20 to form the iron piece insertion portion 20A to be inserted into the left or right correction iron piece 10 according to the characteristics of the screen,

The core is formed integrally with the lower end of the fixing member 20 to support the upper side of the core and has a structure for forming a core upper support protrusion 20B having a predetermined inclination angle to have elasticity in the vertical direction according to the height of the core.

The operation of the holder structure for improving the convergence characteristics of the present invention deflection yoke configured as described above will be described with reference to FIGS. 5 to 7.

First, the core left and right flow preventing projections 2 are formed in the holder of the deflection yoke using the screen characteristic correction iron piece 10 to prevent the left and right flow of the core in a horizontal form, and then the core left and right flow preventing projections 2 are formed. When the trapezoidal fixing member 20 is installed to face the

While the upper side of the core is supported by the fixing member 20, the correction iron piece 10 is inserted to the left or the right according to the screen characteristics, thereby improving the XH unbalance of the screen generated when the vertical deflection coil 3 is assembled. .

That is, bar pieces 20A are formed at both sides of the fixing member 20, and when the bar pieces 10 are inserted at both sides of the piece piece insert part 20A to the left or the right according to the screen characteristics, According to the inserted depth of the correction iron piece 10, as shown in FIGS. 1 and 2, the amount of unbalanced R / B beams can be improved.

In addition, at the center lower end of the fixing member 20, the core upper support protrusion 20B having elasticity as a predetermined inclination angle is formed integrally,

The core upper support protrusion 20B reduces the height difference of the core while supporting elasticity in the vertical direction according to the height of the core when the vertical deflection coil 3 is assembled, and thus supports the upper side of the core. (3) is to facilitate the assembly.

Here, due to the elasticity of the core upper support protrusion 20B, the insertion and removal of the correction iron piece 10 is also easily performed.

As described above, the present invention provides a trapezoidal holder structure in which a core upper support protrusion having a predetermined inclination angle and a correction iron piece insertion unit are integrated to have elasticity according to the height of the core, thereby inserting and removing a vertical deflection coil and a correction iron piece. Since the work can be easily performed, there is an effect of easily improving the XH unbalance generated when assembling the vertical deflection coil among the convergence characteristics of the deflection yoke applied to a large color TV or monitor.
