The conventional technology of the semi-toroidal deflection yoke of CELLS convergence used for a so-called in-line color picture tube in which red, green, and blue electron guns are arranged horizontally is shown in Fig. 1.
In such a conventional example, the winding angle θ1□+θ of the vertical deflection coil 1 is
The wider the picture tube, the thicker the 1□I (14

In view of these points, the present invention provides a new and useful semi-toroidal deflection yoke that has a configuration that allows sufficient space to fix the core to an automatic winding machine and is devised to improve magnetic properties. The specific structure is an in-line color picture tube deflection yoke consisting of a saddle-shaped horizontal deflection coil and a toroidal-shaped vertical deflection coil, in which the left side coil and right side coil are wound in multiple layers at a certain angle from the center of the toroidal core half-way. In addition, the vertical coils are formed such that the winding angles of the left and right coils are the same for each layer, and the difference in winding angle between any layer and the next layer is approximately 1.5°. .

以下、図面に示した実施例に従って本考案を詳述する。Hereinafter, the present invention will be described in detail according to the embodiments shown in the drawings.

It is wound so that the force is @1.5°.

次に、このように1.5°に選んだ理由を述べる。Next, the reason for choosing 1.5° as described above will be explained.

In the vertical deflection coil, the wider the winding angle and the larger the hollow angle (θ0+θ'o), the more the barrel magnetic field becomes.

要がある。
The optimal magnetic field distribution is placed on the vertical axis (Y-axis) passing through the center of the picture tube, and produces a barrel magnetic field of a certain strength (the total of the effective magnetic field integrated along the central axis of the picture tube is the barrel). However, if the winding angle difference K between the adjacent layers is large, the winding angle becomes smaller toward the upper layer, and the average winding angle becomes smaller. Therefore, in order to obtain a predetermined barrel magnetic field on the Y-axis, it is necessary to set a large hollow angle.

However, if this is done, the barrel magnetic field on the diagonal becomes weaker, causing misconvergence as shown in FIG. 6A.

Next, when the winding angle difference K is made smaller, the above case is reversed, and misconvergence as shown in FIG. 6 occurs.

According to the present invention, it is sufficient that the maximum winding angle of the coil wound on the core half, that is, θ2□+θ′2□, is 1400 or less even when forming a deflection yoke for a wide angle. We were able to obtain excellent deflection characteristics.

Since the winding angle on such a half-core core is relatively small, it is easy to fix the half-core to an automatic winding machine.

In addition, in this invention, a part where the coil is not wound is created in the center of the coil winding angle range, and this eliminates unnecessary magnetic fields, so vertical misconvergence at the top and bottom of the center of the screen in Figure 5 is suppressed. It will be done.
