ツ線７ａ、７ｂ。(Problem to be Solved by the Invention) When the saddle-shaped deflection coil 1 is constructed by winding a plurality of thin wires or Litz wires in parallel in this manner, the plurality of conductor wires 7 wound in parallel can be stacked in an orderly manner. As a result, each of the conductor wires 7 is wound at different positions, resulting in a difference in the inductance of each of the multiple conductor wires 7. For example, when seven conductor wires 7 with a wire diameter of 0.14 mm are twisted together, Litz wires 7a, 7b.

, 7b, 7c, 7d, and 7e are not evenly divided into 115 parts, and more of the current flows to those with less inductance, and a phase shift difference occurs between those with less and more inductance. Different currents flow depending on the coupling conditions such as mutual induction between wires and distributed capacitance, and uneven currents often flow in each Litz wire.

になる。This, combined with the fact that each litz wire is wound in a coil shape at different positions, generates a locally distorted and non-uniform magnetic field, which causes the electron beams emitted from each electron gun to This effect results in a partially distorted deflection.

使えないものが多発すると云う欠点がある。Therefore, irregular misconvergence between the electron beams occurs locally on the screen, especially in the peripheral area of the screen where the electron beam passes near the IQ yoke, which significantly degrades the convergence quality. The drawback is that there are many products that cannot be used for high-definition displays.

ストみ高いものになっていた。In addition, in displays where the horizontal deflection frequency is variable, the state of misconvergence of each electron beam on the screen changes due to changes in the horizontal deflection frequency, and this effect becomes larger as the horizontal deflection frequency increases. The fact has become clear that some conventional deflection yokes cannot withstand use even for this type of display, and as a deflection yoke for high-definition displays, productivity is extremely low and costs are high.

た。In this way, conventional deflection yokes have focused on reducing losses due to the skin effect and eddy currents of horizontal deflection coils, and at least one pair of saddles are constructed using horizontal deflection coils to prevent variations in high-precision deflection yokes. No consideration was given to improving productivity and achieving F1 at a low cost of 1~.

。A saddle-shaped deflection coil 1 is made using such stranded wires 17.
4, it easily adapts to the shape of the saddle-shaped space 6 formed between the female mold 2 and the male mold 4, and as shown in FIG. The wires are rolled while being crushed, and the wires are wound up to the tip as in the conventional case, and in the wide part of the space, the wires are piled up and wound in an orderly manner while being crushed horizontally, and the wires are also wound in an orderly manner on the male side, so that the saddle-shaped space 6 is created. It is wound into a coil with less collapse within the coil, and there is less space 9 formed between the convex surface 5 of the male die 4 and the convex surface 5 of the male die 4 at the end of the winding. Due to the electromagnetic force acting between the windings and the positional deviation between the strands when the strands 17 are pushed into the saddle-shaped space when forming the coil end face with the press tool 8, the winding start side and the winding end side are It is possible to obtain a saddle-shaped horizontal deflection coil 14 in which there is little reversal of the twisted wires and the windings are stacked in an orderly manner from the beginning to the end of the winding, with little variation in the winding distribution.

できた。As a result, it goes without saying that the variation in the main 1n direction magnetic field distribution generated by passing current through the deflection coil becomes smaller, but since multiple thin wires are twisted together into one, each The coupling conditions such as mutual induction between thin wires and distributed capacitance are also stable, and it is possible to prevent variations in the inductance between each FP body dose line, current phase shift differences, and local unbalanced currents, so high-frequency current can be passed. However, due to the generation of a locally distorted and non-uniform magnetic field, an asymmetrical component is generated in the deflection magnetic field. b) The cross misconvergence Xv of the horizontal lines of the side beams B and H as shown in the figure has almost disappeared, and the horizontal deflection frequency has been reduced to a level that does not cause any problems even in ultra-high definition displays with a horizontal deflection frequency of 64 kllz or more. .

偏向周波数用途への対応も可能になる。As a result, by twisting multiple phase wires into one tree, the rate at which wires are clogged in the saddle-shaped space 6 (space factor ), and the space factor worsens, so the saddle-shaped coil may be finished larger than the standard one (at the time of design). By using copper wire, it is possible not only to compensate for the poor space factor, but also to increase the wire diameter d of the conductor wire 18, 21 and increase the number of conductor wires. temperature rise can be reduced, making it possible to support large power applications and even higher horizontal deflection frequency applications.

ある。Furthermore, the stranded wires 17 and 22 used in the present invention tend to have a cross-sectional shape that easily changes due to a weak external force even when the number of conductor wires increases or the finished outer diameter increases. It is easy to adapt to the shape, and as shown in Figure 5, the tip of the saddle-shaped space 6 with a narrow gap is rolled while being crushed vertically, and the electric wire is wound up to the tip as in the conventional structure, and the wire is wound in the wide space. In order to stack and wind in an orderly manner while being flattened horizontally, it is necessary to twist the strands at a coarse twisting pitch P, but the pitch P is not limited to that in the example. The most suitable one may be used depending on the line configuration, but the ones that can be adopted in the present invention are:
For the above reason, P=1011III+ or more is required.

ベルにでき、その品位を著しく向上することができた。(Effects of the Invention) As described above, the saddle-shaped in-plane coil of the deflection yoke of the present invention adapts to the shape inside the saddle-shaped space by twisting a plurality of conductor wires at a targeted pitch into one. Since the coils are stacked in the saddle-shaped space of the winding form in an orderly manner from the winding start to the winding end, variations in inductance between multiple conductor wires connected in parallel and winding distribution can be avoided. By reducing the dispersion and generating locally non-uniform magnetic fields, asymmetrical components of the deflection magnetic field are generated, resulting in extremely high resolution of the misconvergence of horizontal side beams, which becomes more prominent as the horizontal deflection frequency increases. Even a simple display device can be made to a level that does not pose any practical problems, and its quality has been significantly improved.

なる。Furthermore, by mixing conductor wires without a fused i4 layer, multiple conductor wires can be formed.
When using a stranded wire made by twisting rod wires together at a coarse pitch to form a single piece of wood, compared to a stranded wire using a conductor wire that all has a fusion layer, the total area is reduced by the amount corresponding to the amount of the fusion layer removed. The rate at which the conductor wires get stuck in the saddle-shaped space (space factor) has been improved, and by twisting the conductor wires, it is possible to compensate for the decrease in the space factor caused by the increase in the number of gaps between the conductor wires. ,
This not only prevents misconvergence caused by the saddle-shaped coil being larger than the standard one, but also makes it possible to increase the diameter of each conductor wire and increase the number of conductor wires. It is possible to reduce the temperature rise of the system, making it possible to handle large electric power and even higher horizontal single load frequency applications.

点を前述の効果に追加できる。In addition, since conductor wires without a fusion layer are cheaper to manufacture than conductor wires with a fusion layer, the cost of stranded wire can be lowered by mixing and using water conductor wires without a fusion layer. Benefits can be added to the aforementioned effects.

なる分だけ生産コストが安くなる利点がある。Furthermore, to construct a single stranded wire by simultaneously twisting a large number of conductor wires together, it is possible to construct a single stranded wire by twisting a relatively small number of conductor wires together in units of 9 wires in advance. Compared to the case where a single stranded wire is used, the finished outer diameter can be made smaller, and the production cost is reduced by one less twisting step.

でき、その工業的価値は大きなものがある。Furthermore, because conventionally a large number of conductor wires or stranded wires (Litz wires) were wound simultaneously in parallel, the wire transmission system of the winding machine became complicated, resulting in variations in the tension between each conductor wire and In order to obtain a stable coil, it was difficult to manage the operation of the winding machine due to variations in the way the wire slides into the winding form, etc. However, if the winding machine is unified as in the present invention, the wire feeding becomes easier. The system becomes simpler, there is no variation in the tension between each conductor wire, the number of times the winding machine has to stop to supply the wire due to a wire being lost in the middle of winding is reduced, and the simple configuration reduces troubles. It is now possible to operate the equal winding machine continuously for a long time with less generation.
The winding temperature becomes stable, and a stable saddle-shaped 1U coil can be produced with high productivity using a simple and inexpensive winding machine, which is used for high-quality, high-resolution displays, etc. It is possible to produce a highly difficult deflection yoke with a high yield, and its industrial value is great.
