Description

Structure of magnetic fixed partial for screen VCR correction in coil separator of deflection yoke}

When the deflection yoke (DY) is mounted on the CRT, the present invention has a green line, which is a horizontal line on the upper and lower sides, located outward or inward as compared to red or blue lines. It relates to a magnetic piece to be corrected when, and particularly relates to a fixing portion for fixing the magnetic piece.

In general, the deflection yoke used in the CRT of the electron gun in-line array type, such as a high-resolution monitor, has a neck portion at the upper portion and a screen portion at the lower portion of the inner circumferential surface of the coil separator assembled in pairs. The horizontal deflection coil is wound around the vertical deflection coil, and the core is assembled by a clamp.

RGB (green, red, blue) formed on the fluorescent surface (screen) of the CRT by installing the deflection yoke configured as described above on the neck of the CRT and deflecting the electron beam emitted from the electron gun of the CRT in left, right, or up and down directions Hit to determine the dice on the screen.

As described above, the electron beam emitted from the electron gun of the CRT has the characteristics of the screen as shown in Fig. 1 (a) (b) due to the error of mechanical mechanism and its own error of deflection yoke such as the dispersion of horizontal and vertical deflection coils. The positions of the green line 110, the red line 130, and the blue line 120 forming horizontal lines on the upper and lower sides of the screen are changed.

For example, a phenomenon in which a green line is positioned outward or inward as compared to red or blue lines is called a VCR.

When the above phenomenon occurs, the VCR correction magnetic piece is corrected by using a conventional magnet. In the conventional installation of the VCR correction magnetic piece 5, the upper part of the frame 4 of the comma-free coil 3 as shown in FIGS. And fixed with adhesive using an adhesive.

When fixing the VCR correction magnetic piece 5 to the frame 4 of the comma-free coil 3 by using an adhesive as described above, when fixing the VCR correction magnetic piece, the VCR correction magnetic piece does not deviate from the corrected position. It has to pay attention, and it takes time for the adhesive to harden and it has a disadvantage of low working efficiency.The VCR correction magnetic piece is installed close to the comma free coil, so it is shorted with the comma free coil. It always implies the risk of fire, and has a disadvantage in that a functional impairment is caused by an error in the upper and lower horizontal lines because it is easily separated from the small impact force.

The present invention devised to solve the disadvantage that occurs when fixing the screen VCR correction magnetic piece of the conventional deflection yoke coil separator as described above, the comma-free coil is installed is installed with a flat plate formed on the neck portion of the deflection yoke A horizontal plate member is formed in the pre-fixed frame, and a VCR correction magnetic piece fixing part having an insertion hole formed by an insulating wall spaced apart from the lower part of the pre-fixing frame is formed. It is easy to improve the assembly productivity by shortening the working time according to the screen VCR correction; Secondly, it is installed at a sufficient distance from the comma-free coil and at the same time has an insulating wall to prevent malfunction due to short; Third, to provide a structure of the VCR correction magnetic piece fixing portion of the coil separator for deflection yoke that is firmly fixed and can prevent the deviation of the VCR correction magnetic piece generated by the impact.

The present invention for achieving the above object, the horizontal deflection coil is wound around the inner circumferential surface of the coil separator assembled as a pair having a neck portion at the top and the screen portion at the bottom, and the vertical deflection coil wound on the outer circumferential surface Is assembled by a clamp, and is located above the comma-free coil which is installed as a flat plate formed around the neck, and is composed of green line, red line, and blue line. In the VCR corrected magnetic piece for correcting the position of the horizontal line, the VCR corrected magnetic piece fixing part extended to the upper part of the comma free fixing frame on which the comma free coil installed on the flat plate formed in the neck part is mounted is the comma free coil fixing frame. VC is formed by extending the horizontal plate in the horizontal direction on both sides, the upper portion of the coil mounting portion The R correction magnetic piece fixing portion has a horizontal plate member extending in a horizontal direction on both sides of the comma-free coil fixing frame, and an insulating wall is formed between the horizontal plate members, and the insulating wall has a VCR correction magnetic piece inserted and fixed. It is achieved by being spaced apart from each other and having insertion widths formed between the horizontal plate and the insulating wall.
