Along with this, it is necessary for the stranded wire to have higher strength, but in the case of pure copper wire, if a non-annealed wire is used to increase the strength, it becomes difficult to twist the wire and a stranded wire with good straightness can be obtained. There was a problem of not having. Further, when a high-strength copper alloy wire is used, there is a problem that twisting becomes extremely difficult without annealing and a twisted wire with good straightness cannot be obtained.

And a winding step, which is a method for producing a highly conductive and high strength stranded wire. Since winding a high-strength stranded wire causes distortion, it is preferable that the stranded wire is continuously wound in a straight line without being wound and then cooled after being wound.

By continuously heating the stranded wire in a straight line without winding it and then cooling it, the internal strain generated in the stranded wire process is alleviated without significantly lowering the strength. It is characterized by preventing. If the working ratio of wire drawing is less than 90%, the strength is not sufficiently improved, and the working ratio is 9 in order to sufficiently improve the strength.
It is desirable to be 9% or more.

Because it is done. After that, when wound around a spool or the like, the straightness may be slightly impaired and a so-called winding tendency may be generated, but as is generally known, the diameter of the spool is larger than the diameter of the twisted wire. Is sufficiently large so that practically no inconvenience occurs.

When g is less than the lower limit, sufficient strength cannot be obtained, and when it exceeds the upper limit, workability and conductivity are slightly deteriorated. Therefore, the above-specified ones are preferable.

最も好ましい結果が得られたからである。In the case of the long stranded wire which is the object of the present invention, when it is heated and cooled in a wound state, the straightness is poor. For example, it is coated with vinyl chloride or the like to be used for automobile wiring. If used, straightness is poor and assembly workability is impaired. In the present invention, it was found that the straightness is good and the practically sufficient strength and conductivity can be obtained by continuously performing the heat treatment in a linear state. In addition, when the heat treatment is continuously performed in a straight line state, the straightness can be further improved by applying tension. In this case, the larger the tension applied to the material to be heat-treated is, the more remarkable the effect is. However, if the tension is too large, a wire breakage accident occurs, so that the yield strength in the heated state is usually 20 to 70. % Is preferable. Further, it is preferable that the condition for heating and cooling the stranded wire is such that the tensile strength of the stranded wire that is cooled after heating is 70 to 95% of the tensile strength of the stranded wire before heating, which exceeds 95%. In this case, the straightness is not sufficiently improved, and when it is less than 70%, the straightness is sufficient, but the strength is remarkably reduced, and therefore, the practically preferable range is 70 to 95%.

A composite wire coated with a 2 μm Ag or Ni layer may be used, but this is to improve the corrosion resistance of the body or the copper alloy wire, especially to improve the electrical contact characteristics in a corrosive environment and high temperature. Is 0.1 to 2 μm, the effect is insufficient if less than 0.1 μm,
This is because if the thickness exceeds 2 μm, the effect is saturated and the cost is unnecessarily increased.
