ランスが崩れることになる。By the way, the distribution part 14 of the bobbin 2 and the crossover part
The multi-core parallel conductor 15 is inserted into the coil winding groove 30 at the boundary area between 12 and 13.
When winding, it is necessary to bend the multi-core parallel conductor 15 and wind it, and when this multi-core parallel conductor is bent and wound, the multi-core parallel conductor has a band shape and the radius of curvature is different between the inside and outside of the bend. In addition, the outside of the line is pulled inward, which inevitably causes the line to rise or bulge. Due to the turbulence phenomenon caused by the lifting and bulging of such lines,
There is a difference in the laminated shape of the multi-core parallel conductors 15 between the case where the multi-core parallel conductor 15 is wound around the boundary region between the distribution portion and the crossover portion and the case where the multi-core parallel conductor 15 is wound around the boundary region between the crossover portion and the distribution portion. For example, the lamination shape of the multi-core parallel conducting wire 15 at the point B in the boundary region between the distribution portion and the crossover portion is in a state as shown in FIG.
The laminated shape of the multi-core parallel conductor 15 at the point C in the boundary region between the crossover portion and the distribution portion is in a state as shown in FIG. 2B. From these figures, the gap 17 inside the coil winding groove at the point C of the boundary region between the crossover and the distribution portion is larger than the gap 17 between the groove at the point B of the boundary region between the distribution portion and the crossover portion. The lamination shape of the core parallel conductive wire 15 also swells at the point C inside the groove and is more disturbed than at the point B. The imbalance due to the left and right winding disturbance also occurs between the other left and right coil winding grooves, and thus the coil distribution balance in the left and right boundary region is lost.

The portion that moves to the crossover portion and the portion that moves from the crossover portion to the distribution portion are different, and the left and right balance of the coil distribution is lost.

た。As described above, if the laminated state of the multifilamentary parallel conductors 15 is different between the coil winding grooves 30 in the left and right boundary regions of the bobbin 2, the balance of the left and right coil distributions is lost.
There is a problem that precise control of the deflection magnetic field becomes difficult.
