平行多芯線３を巻回することにより形成されている。This deflection yoke is a strip shape as shown in FIG. 9 in a coil winding groove 2 formed in a direction connecting the head side and the neck side on the inner peripheral surface of a bobbin 1 having a boshish shape shown in FIG. It is formed by winding the parallel multicore wire 3.

である。However, since the conventional deflection yoke uses the strip-shaped parallel multi-core wire 3 having the bare copper wire 4 as the core wire 4, the conductor cross-sectional area of the strip-shaped parallel multi-core wire 3 becomes large. During the deflection operation of the deflection yoke, as shown in FIG. 10, the eddy current i generated when the deflection magnetic field φ H passes through the strip-shaped parallel multifilamentary wire 3 becomes large, and accordingly, the heat generation due to the eddy current loss is extremely large. However, it is virtually impossible to use.

In order to match the impedance with the deflection circuit,
Generally, DC resistance is about 30 ohms and inductance is about
The value is set to 25 mH, but for that purpose, it is necessary to set the number of turns of the strip-shaped parallel multifilamentary wire 3 to about 270 turns on either side of the left and right sides. On the other hand, the winding time of the winding machine that winds the strip-shaped parallel multifilamentary wire 3 takes about 10 seconds per turn and 24 times a day.
Even if it is fully movable for a period of time, only about 16 sets of deflection coils can be manufactured in one day, which causes a problem that the cost of the deflection coil becomes high.

Compared with the case of forming a deflection coil by winding one strip parallel multi-core wire in the conventional example, the number of windings of the strip-shaped polymerized multi-core conductor wire can be reduced, and the coil winding time can be shortened accordingly. In addition, the efficiency of the coil winding work can be improved, and the cost of the deflection coil can be significantly reduced.

This does not occur, so that heat generation in the coil due to eddy current loss can be suppressed.
