Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a semidroidal deaf deflection yoke used in a color television summer image receiving system, and a winding device for winding a vertical coil around the deflection yoke.

The one-way yoke of the SE()0IDAL type has a structure in which 111Lm is wound around =1 of a ferrite table divided into two by a predetermined number of turns, and this is wound in multiple layers. Winding of each layer is then started from a fixed direction. That is, in FIG. 1(g), 41!4 is wound around the core 8 from the winding start 2, and returns to the original position along the return line 5, as shown in FIG. 41(A). The same thing is the first
1m (C) to C). Then, the winding is completed by 5 at the end of the first winding. A return is made from the winding end 3 of each layer to the winding beginning 2 of the next layer, and as shown in Fig. 1 (A>, ld), vlK, this return involves one or two turns of the core 8, and is a large winding. An angle is formed.

Figure N2 shows a coil wound around the core 8 of the deflection yoke 1. That is, the winding 4!4, which starts nine windings from the opening lI9 toward the neck nozzle 10, forms a return @S with a large core index angle inside and outside the core 8, and this return $5 is connected to other aligned windings. The winding 4 intersects with the winding 4.・This return Ia5 disturbs the winding distribution by causing a positional shift of the next layer to be wound.
This causes the coil characteristics to become unstable. By reducing the angle of the return wire 5 and winding as many wires as possible from the winding end 5 to the winding start 2, it is possible to prevent the wire from diagonally oriented inside and outside the l core 8. However, if many electric wires are wound around the core 8 at the time of return, bright and dark stripes and distortions called ringing phenomenon occur on the 77 screen. These light and dark stripes and distortion are proportional to the number of turns at the time of return, and in order to avoid the ringing phenomenon, a return with a large index angle of 1 or 2 turns is required. .

Returning to Figures 81 (#) and (p), the winding layer of the deflection yoke employs a one-winding method called hollowing (indicated by mutual symbols). This forms a part in the center of the core 8 that is not wound, and the left and right windings are connected by a hollow hole of 1 m7. This hollow alternation is necessary due to the characteristics of the coil, and it is necessary to perform it in all the layers or some of the layers.

This hollow angle can be as high as 90 degrees for hired workers. Therefore, the same problem as the return ms occurs. Figure 5 shows deflection yoke 1
It shows the hollow A in .

Note that in both FIGS. 2A and 2I5, solid lines indicate the windings inside the core 8. .

As explained above, return-5 and hollow? m7
This has been considered a problem in the past because it causes disturbance of the coil characteristics and requires a lot of time for the work #1. 4
Figure 4 shows a deflection yoke in which return @S and hollow N7 are mixed.

In the deflection yoke 1, since the winding inside the core 8 affects the coil characteristics, it is necessary that diagonal lines such as the return II 5 and the hollow +117 do not occur in the core 8. Therefore, even in the conventional winding system [I], the core 8 is indexed at a large angle when the flyer 21 is on the outside of the box 18, and the core 8 is indexed at a small angle when it is on the inside. However, as shown in FIGS. 2 and 5, there is a distance l between the tip of the ear 21 and the end surface of the opening 9 of the core 8.
The electric wire is oriented diagonally inside the core 8 by this amount.

Also, as a method of performing the return and hollowing outside the core 8, the opening 119 of the core 8 and the neck ill? A ring having some unevenness is attached to the ring with adhesive tape or the like, and an electric wire is wound inside the recess, and the return wire 5 and the hollow N7 are passed diagonally outside the core 8, and the ring is attached to the protrusion of the ring. Instead of hooking the wires on the wire to prevent sideways slipping and making the windings parallel to each other inside the core 8, or using the ring with the unevenness described above, there is a method in which wires are glued with an adhesive and the slippage is prevented. etc. have traditionally been done. However, all of these methods have the disadvantage that the number of parts increases and the number of man-hours increases, making the deflection yoke expensive.

The present invention eliminates the drawbacks of the prior art, and its purpose is to provide a uniform deflection yoke with a uniform quality and less variation in coil characteristics without causing ftm comrades to develop inside the core. Deflection yoke reliably and
The purpose is to provide a winding device that can produce high DC efficiency.

In order to achieve the above object, the present invention includes a rotating part that holds one layer of the core and rotates the core around the center; turn 7
The layer and this rotating drive part, and the outside of the core
An electric wire guide section that holds the area within the core and holds the wax from the flyer at that position so that it is parallel to the core center axis, and this electric wire guide section is attached to the core as necessary. It is characterized by a winding device of a deflection yoke that moves to a position at a predetermined position and a deflection yoke that performs ttM, and a deflection yoke that does not form the winding 1 that intersects on the circular side of the °C core due to the zero winding. .
