Description

[Detailed Description of the Invention] The present invention relates to a deflection yoke that is attached to a cathode ray tube of a color television receiver and deflects an electron beam.

FIG. 1 shows a conventional deflection yoke, with FIG. 1a being a front view and FIG. 1A being a side sectional view.

In Figures 1a and 1b, 1 is a horizontal coil that is closely attached to the inner surface of the separator 2, and the neck end conductor 3 of the horizontal coil 1 has a high precision in the dimensions of the unconnected separator 2 provided on the separator 2. is required.

In addition, in FIG. 1, 7 is a vertical coil.

An object of the present invention is to provide a deflection yoke equipped with a separator that can accommodate many types of horizontal coils and can be used satisfactorily even with low dimensional accuracy.

The present invention will be explained below with reference to examples.

Figure 2 is a diagram showing the deflection yoke according to the present invention, and Figure 2a
Figure 2 is a front view, and Figure 2 is a side sectional view, with the vertical coils omitted.

FIG. 3 is a perspective view of a separator in the deflection yoke of the present invention.

The feature of this deflection yoke is that a convex strip 6 is provided on the large diameter portion 2a of the separator 2', and the convex strip 6 extends to the outer surface 5b of the conductor 5 at the opening end of the horizontal coil 1. The horizontal coil 1 is held by the large diameter portion 2a of the separator 2' by pressing the horizontal coil 1.

Of course, the inner surface 5a of the opening end conductor 5 of the horizontal coil 1 is in close contact with the separator 2'.

The width d of the housing 4 of the separator 2' is larger than the width of the neck end conductor 3 of the horizontal coil 1, and the separator 2' is compatible with many types of horizontal coils having different lengths of the body 1b of the horizontal coil 1. It is chosen so that it can be done.

Of course, the dimensional accuracy does not need to be high.

Therefore, since the housing 4 and the neck end conductor 3 are not fitted together, the neck end conductor 3 is inserted into the housing 4 with a margin, and the separator 2' is made of various types with different lengths of the body part 1a. Compatible with horizontal coil 1.

As explained above, in the deflection yoke of the present invention, a convex strip is provided on the large diameter part of the separator, and this convex strip presses the outer surface of the conductor at the opening end of the horizontal coil to hold the horizontal coil. Because of this structure, it is possible to use a highly versatile separator that can be used with many types of horizontal coils, and there is no need to require high dimensional accuracy of the separator.

Moreover, when the design of the horizontal coil is changed, there is no need to change the design of the separator accordingly.
