励磁巻線（４）が第７図に示すように埋設される。5 and 6 show a conventional deflection yoke core (1), which has a trumpet shape in which one end has a small diameter and the other end has a large diameter. The inner surface of the core (1) facing the cathode ray tube (not shown) is provided with a plurality of grooves (2) over the entire inner surface from one end surface to the other end surface in the core axial direction. Exciting windings (4) for creating a deflection magnetic field are buried in these grooves as shown in FIG.

つた。In the conventional deflection yoke configured as described above, since the plurality of grooves 2 are formed over the entire length in the core axial direction, that is, from one end surface to the other end surface, the position in the core axial direction varies. That is, the winding distribution function with respect to the circumferential angle does not change much. Therefore, it is not easy to adjust the magnetic field distribution, and when applied to a color cathode ray tube, even if color misregistration (misconvergence) occurs, it is difficult to correct it by the deflection yoke.

に調整可能な偏向ヨークを得ることを目的とする。The present invention has been made in view of the above-mentioned points, and makes it possible to change the distribution function related to the circumferential angle of the excitation winding applied to the core depending on the position in the core axial direction. It is an object of the present invention to obtain a deflection yoke that can reduce color misregistration (misconvergence) and can adjust the raster shape on the screen to an appropriate one.

軸方向に延在する複数の溝を形成するとともに、コアの
大径側内面を平坦面としたものである。In the deflection yoke according to the present invention, a plurality of grooves extending in the axial direction of the core are formed on the inner surface of the core on the small diameter side, and the inner surface of the core on the large diameter side is made flat.

可能ならしめるものである。According to the present invention, a plurality of grooves formed on the inner surface of the core on the small diameter side are arranged in a predetermined distribution function regarding the positioning and circumferential angle of the excitation winding, and the inner surface of the core on the large diameter side is flat. This allows the surface to move in the circumferential direction of the excitation winding and the distribution function in the circumferential direction of the excitation winding to be adjustable.

るものである。An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. 1 and 2 show a core (1), and a plurality of grooves (2) for burying an excitation winding extending in the core axial direction on the inner surface of one end of the core (1) on the small diameter side. Has a groove forming portion (I) and a flat surface on the inner surface of the other end of the core (1) on the large diameter side, that is, a flat portion (II) in which no groove is formed. A guide groove (5) for fixing the position of the excitation winding on the screen side is formed on the other end surface of the core (1). The excitation winding includes a toroidal type vertical deflection winding (4a) and a saddle type horizontal deflection winding (4b), and as shown in FIGS. 3 and 4, the horizontal deflection winding (4b) ) Is wound on the vertical deflection winding (4a).

位置を変えるようにしたものである。Next, a description will be given of a method of adjusting the winding distribution in the circumferential direction in the excitation winding, particularly the horizontal deflection winding (4b) in the deflection yoke configured as described above. FIGS. 3 and 4 show that the horizontal deflection winding (4b) wound on the vertical deflection winding (4a) changes its position in the circumferential direction at the groove-free portion, that is, the flat portion (II). It was done.

に調整される。広角偏向の平面に近いスクリーンの陰極
線管では方形ラスタとなつて現れることになる。In this way, in the horizontal deflection winding (4b), the exciting current has a distribution close to a sine wave with respect to the angle θ on the one end side where the diameter of the core (1) with the electron gun is small, whereas the diameter of the core (1) Since the winding on the other end side where the angle is large tends to be concentrated at the position where the angle θ is small, the magnetic field generated is of the pink twitch type. As a result, the raster on the screen is adjusted to a barrel shape. In a cathode ray tube with a screen close to the plane of wide-angle deflection, it will appear as a square raster.

できる。In short, in this embodiment, it is possible to change the position of the horizontal deflection winding (4b) with respect to the angle θ in the flat portion (II) where no groove is formed, depending on the position in the core axial direction. As a result, it is possible to adjust the winding distribution regarding the circumferential direction angle depending on the position of the horizontal deflection winding (4b) in the core axial direction.

る。In the above-mentioned embodiment, the groove for burying the excitation winding is not provided at a portion where the inner diameter of the core is large, but is a flat portion (II). However, the flat portion (II) does not reduce the deflection efficiency. The flat portion (II) has almost no adverse effect. This is because the deflection magnetic field strength at the one end side where the deflection yoke inner diameter is small, that is, at the neck portion of the cathode ray tube, is not so much decreased because the groove is not provided on the other end side where the core inner diameter is large, and is not so much decreased. is there.

Further, although the vertical deflection winding (4a) is shown as a toroidal type, it may be a saddle type.

有するものである。As described above, the present invention forms a plurality of grooves in which the excitation winding extending in the core axial direction is embedded in the inner surface of the core on the small diameter side, and the inner surface of the core on the large diameter side is a flat surface. The excitation winding can be moved in the circumferential direction on the flat surface on the large diameter side of the core,
This has the effect that the winding distribution function relating to the circumferential angle of the excitation winding can be easily changed, and the magnetic field distribution can be easily adjusted.
