Description

[Brief explanation of the drawing]

Figure 1 is a front view of the deflection core related to the deflection yoke of the present invention;
The figure is a cross-sectional view along the Y axis in Figure 1, Figure 3 is a partial cross-section of the deflection core in Figure 1 with a winding guide attached, and Figure 4 is a front end winding on the deflection core in Figure 1. Figure 5 is a front view with the guide attached, Figure 5 is a rear view of the core shown in Figure 1 with the rear end winding guide attached, Figure 6 is a partial cross section of the deflection coil wound around the deflection core shown in Figure 1. The enlarged view, FIG. 7, is a front view showing another embodiment of the deflection core according to the present invention. In the figure, 1 is a deflection core, 2 is a winding groove, 3 is a convex strip, and 4 is a communication groove. Figure 6 2-17 1 9 Figure 5

Claims (1)

[Scope of utility model registration request] An even number of winding grooves extending in the direction of the tube axis is formed on the inner surface of the deflection core, and a communication groove spanning adjacent grooves is formed to create an even stronger bottle cushion magnetic field or a stronger magnetic field on the screen side of the core. A deflection yoke characterized by being configured to form a deflection magnetic field that becomes an even stronger barrel magnetic field.
