ムの偏向を行う偏向ヨークに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a deflection yoke that is fixedly attached to a cathode ray tube such as a television picture tube and deflects an electron beam emitted from an electron gun.

クの三つに分けられる。Conventional configurations and their problems In general, deflection yokes include an all-saddle type deflection yoke that uses saddle-type coils for both vertical and horizontal deflection, and a toroidal-type coil for vertical deflection and a saddle-type coil for horizontal deflection. There are three types of deflection yokes: a semi-toroidal type deflection yoke, which uses toroidal coils for both vertical and horizontal deflection, and an all-toroidal type deflection yoke, which uses toroidal coils to perform both vertical and horizontal deflection.

行ないづらいという欠点を有していた。 Among these, the saddle type coil used in the all-saddle type deflection yoke and the semi-toroidal type deflection yoke has two coils 1 wound in a saddle shape facing each other, as shown in the perspective view in Fig. 1. A core 2 is combined around the outer periphery of the coil 1 as shown in FIG. 2, and most of the magnetic field generated by the coil 1 is utilized in the space inside the core 2. Here, in a cathode ray tube that has an electron gun or in-line gun that emits a central beam and a pair of side beams,
By making various changes to the windings of the coil, we intentionally change the magnetic field distribution inside the core to form a distorted magnetic field, and the "red" emitted from the in-line gun is created by creating a distorted magnetic field.
The superimposition of the "green" and "blue" electron beams was adjusted, and the sensitivity of each electron beam was adjusted. However, this method has the disadvantage that it is difficult to make fine adjustments after winding is completed.

ことを目的とする。Purpose of the Invention The present invention has been made in view of the above-mentioned conventional drawbacks, and can easily change the magnetic field distribution in the core internal space with a simple structure, without increasing power consumption. Another object of the present invention is to provide a deflection yoke that can improve the sensitivity of electron beams.

した。Structure of the Invention In order to achieve the above object, the deflection yoke of the present invention has the following features:
A pair of correction pieces made of magnetic material is arranged between a pair of opposing saddle-shaped coils, a protrusion is formed in the center of each correction piece, and both correction pieces are connected to a window formed in the horizontal deflection coil. The above protrusion was located at the center of the correction piece, and the protrusions of both correction pieces were arranged so as to face each other.

Each saddle-shaped coil 1 for horizontal deflection is provided with a window. When a current is passed through the saddle-shaped coil 1 wound within the coil 2, magnetic fluxes 3, 4, 5, 6, and 7 are generated in the core 2 internal space. FIG. 4 shows a pair of correction pieces 8 and 8' made of magnetic material.
Each of the correction pieces 8 and 8' has a protrusion formed in its center. Then, as shown in FIG. 5, these correction pieces 8 and 8' are attached in contact with the core 2 so that the protrusion is located in the center of the window formed in the saddle-shaped coil 1. .
By doing so, the magnetic resistance between the correction pieces 8 becomes smaller, so that the strength of the magnetic flux 7 becomes stronger.

By doing so, it is possible to correct the horizontal deflection magnetic field that passes vertically inside the cathode ray tube, and it is possible to make corrections that increase the density of the horizontal deflection magnetic field, especially in the center. The beam deflection angle can be increased.
