The present invention relates to a deflection yoke mounted on an in-line picture tube in which a plurality of electron guns are arranged in-line.

ずるものであつた。 Recently, as shown in FIG. 1, electron guns 1, 2, and 3 of Blue B, Green G, and Red R are used as deflection yokes mounted on a picture tube in which electron guns 1, 2, and 3 of Blue B, Green G, and Red R are arranged in-line. The so-called self-convergence type is capable of adjusting the applied amount of the deflection magnetic field generated by the deflection yoke for each electron beam emitted from the electron beams emitted from the electron beams 3 and 3, thereby obtaining good convergence characteristics without using a convergence yoke. A deflection yoke has been developed and put into practical use.
However, in the deflection yoke described above,
Due to deviations in the line symmetry of the vertical deflection magnetic field generated by the vertical deflection coil, or variations in picture tube performance, etc., the upper and lower points of the Y-axis on the screen may differ from the center when viewed from the network side. The blue electron gun 1 is located on the right side, or the red electron gun 3 is located on the left side.
The sensitivity of one of the rasters B and R (for example, the sensitivity of raster R) is insufficient in the vertical direction, as shown in Figure 2.
This caused misconvergence in the vertical direction on the screen S.

管用偏向ヨークに関するものである。 The present invention relates to a deflection yoke made in view of the above matters, and in particular, a substantially cross-shaped magnetic piece is attached to a bobbin near one side of an electron gun arranged in-line parallel to the tube axis of the deflection yoke. This invention relates to a deflection yoke for an in-line picture tube, which is movably attached to the rear surface of the enlarged rear part of the picture tube.

and a horizontal deflection coil 14 wound in a hollow shape on the inner surface of the core 11 via a bobbin 13, and a tightening tongue piece 13 provided at the rear end of the bobbin 13.
By reducing the diameter of electron gun 1 with a tightening tool 15 such as a tightening band, three electron guns 1, 2, and 3 of blue B, green G, and red R are arranged in a predetermined position on a picture tube 16 arranged in-line. Fixed in position. Rear enlarged portion 13 of the bobbin 13 that constitutes the deflection yoke 10
As shown in FIG. 4, a pair of sliding grooves 17 are formed on the back surface 132A of the tube 2, parallel to the tube axis, and located above and below the clamping tongue 131. , a magnetic piece 1 made of a magnetic material such as ferrite or vermalloy is located on the electron gun 3 side of the lead R (left side with respect to the tube axis) with the tightening tongue piece 131 as a boundary.

The deflection yoke 10 is placed on the picture tube 16 with the approximately cross-shaped magnetic piece 18 attached to the electron gun 3 side of the reed R via the sliding groove 17 formed on the back surface 132A of the rear enlarged portion 132. Attach and fix. After that,
The magnetic piece 18 is moved along the sliding groove 17, adjusted to an optimal position, and fixed by adhesive or other means. At this time, the vertical deflection magnetic field generated by the vertical deflection coil 12 is concentrated (increased) on the raster R generated by the reed gun 3 due to the action of the magnetic piece 18, and in particular, As a result, the leakage amount of the vertical deflection magnetic field applied to the raster R increases (by varying the length of the bent portion 183, the leakage amount can be controlled arbitrarily). ), the sensitivity of the vertical deflection component of raster R increases, and the misconvergence on the screen is corrected in the vertical direction (up and down) of the screen S, as shown in Figure 6, and the sensitivity of the vertical deflection component of raster R increases. , G, and R are in the best condition. Further, the magnetic piece 18 is configured in a substantially cross shape, and the horizontal piece 1
A bent part 183 is provided at one end of 82,
The magnetic piece 18 acts only on the vertical deflection magnetic field, has no effect on the horizontal deflection magnetic field generated by the horizontal deflection coil 14 (does not cut part of the horizontal deflection magnetic field), and does not act on the horizontal deflection magnetic field generated by the horizontal deflection coil 14. All deflection magnetic fields operate effectively.

Of course, it can also be applied to the situation where the raster B sensitivity generated by the blue electron gun is insufficient (under). It is located and attached to the gun side.

A substantially cross-shaped magnetic piece consisting of a horizontal piece and a vertical piece is movably attached to the left or right side of the tube axis, and one end of the horizontal piece of the magnetic piece is moved forward in the tube axis direction. It is bent approximately at right angles to the horizontal piece, and the vertical angle at the upper and lower Y-axis points on the screen is caused by deviations in line symmetry of the vertical deflection magnetic field or variations in picture tube performance. Directional misconvergence is corrected, and with a simple configuration of simply providing a nearly cross-shaped magnetic piece, good convergence characteristics can always be obtained for the entire screen without affecting the horizontal deflection component. It is something that can be done. In addition, by appropriately adjusting the mounting position and shape (for example, the length of the bent part) of the magnetic piece, it can be applied to various deflection yokes.
It is highly applicable, especially for adjusting the position of the deflection yoke vertically and horizontally with respect to the tube axis (oscillation adjustment).
It is extremely effective as a self-convergence type deflection yoke with no oscillation.
