いう問題があった。Detailed Description of the Invention "Industrial Application Field" The present invention provides an improved method that can improve the high frequency gain, improve the space factor during winding, and further prevent the looseness of the wire. [Conventional technology 1] Litz wires, which are made by twisting enamelled wires to make them multi-conductor, have been used since early times in high-frequency communication equipment, etc.
As the frequency of the current increases, the AC resistance increases due to the skin effect and the resistance becomes larger. The purpose is to divide the skin current 7 and prevent the increase in AC resistance mentioned above. 6 In recent years, as electrical equipment has become smaller, more efficient, and more energy efficient, inverter control has become more frequent. I=゛B is used to improve image quality in the deflection yoke of TVs, etc.
As the T drive frequency becomes higher, the demand for Litz wires is increasing.9 Knotts wires are made by twisting together many enamelled wires as described in 1 above, or by twisting them together. Regardless of whether the twisting method is concentric twisting, collective twisting, or compound twisting, when the terminals are cut, the strain during twisting is released all at once, and the strands tend to fall apart, making it difficult to wind coils. There was a problem that terminal processing became extremely troublesome.
上記端末処理の問題のほかにも、上記のようにバラケ易
いとこれを角形ボビンに巻線した際に角部で電線の撚り
形状につぶれが生じ、円滑に巻線することか困難になる
という問題もある。In addition to the above-mentioned problem of terminal processing, if the wires tend to come apart as mentioned above, when the wires are wound on a rectangular bobbin, the twisted shape of the wires will be crushed at the corners, making it difficult to wind the wires smoothly. There are also problems.

[発明か解決しようとする課題]
リッツ線にとって宿命的ともいえる素線のバラクの問題

的に断面円形状の撚線に構成するのが通常であった。[Invention or Problem to be Solved] The above problem has solved the problem of bare wires, which can be said to be a fateful problem for Litz wires, but Litz wires still have the problem of a decrease in space factor. 6 In other words, the conventional litz wire has an enamel coating 2 on the conductor 1.
An enameled wire coated with 1. As shown in FIG. 8, A and LA were usually twisted concentrically, in clusters, or in combination to form a stranded wire with an overall circular cross section.

く、実用−F問題かあった。In order to improve this space factor, it has been proposed to twist the litz wires and then roll the whole into a rectangular shape as shown in FIG. However, in the case of forced deformation in this way, a very large stress is applied to the strands IA particularly located in the central part, and the elongation and distortion of the enamel film 2 become large. There was a great risk of cracking in the film 2, causing pinholes, and impairing insulation reliability, which was a practical problem.

成される。[Means for Solving the Problems] The gist of the present invention is to arrange and strand a plurality of enamelled wires each having a circular cross section in a #12 row, thereby forming a flat stranded wire having a rectangular overall cross section. This is due to the fact that it is configured so that
In that case, one or more of the wires constituting the flat stranded wire is made of self-bonding enamelled wire, mixed between ordinary enamelled wires, and after being twisted into the flat stranded wire, 6 [Action 1: As in the conventional example, the stranded wire with a circular cross section is Instead of rolling the wires into a rectangular shape, when twisting the wires, arrange the wires in two horizontal rows and twist them so that they have a rectangular cross section. [Example] The present invention will be described below with reference to Examples.7 Figure 1 is a perspective view of a litz wire according to the present invention.
The figure is an end view thereof. In the present invention, an enameled wire 1. A and LA are twisted in two rows horizontally as shown in the figure, so that the entire # section becomes a flat stranded wire with a rectangular shape.

The enameled cable wires IA and LA are sent out from the delivery pobbins 21 and 21 of the delivery device 20, twisted into the above-mentioned flat shape in the flat twisting ties 22, and then passed through the forming ties 24 to change the overall shape. Alternatively, it may be wound up using the winding machine 25.

ある。Furthermore, as shown in FIG. 7, the flat stranded wire 10 may be rolled and welded from the short side direction at a reduction rate of 5 to 40% using a rolling roll 26, so as to be configured as shown in FIG. 6. Thereby, the space factor can be further improved. (With a rolling reduction ratio of 40%, it is possible to increase the space factor from 60% before rolling to 85% after rolling.) Experiments have shown that with a rolling reduction ratio of 5 to 40%, the occurrence of pinholes can be eliminated. Confirmed 9
Litz wires having the configurations shown in Figures 2, 4, and 5 above were arranged in two layers of 7 wires each using 0.2111 m diameter enameled wire (2UEW) and self-bonding enameled wire (28B3UEW), resulting in 14 wires. After manufacturing flat stranded wires, each wire was wound into a square pobbin, and no crushing phenomenon was observed at the corners, indicating good winding performance.2
[Effects of the Invention] As described above, according to the Litz wire according to the present invention, the space factor in the winding can be improved, and at least one of the strands is made of a self-bonding enamelled wire. By doing so, it is possible to prevent looseness between the strands, which is very useful in industry.
