のである。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire conductor for a harness that can be used, for example, for a wire harness for an automobile.
［従来の技術］ 近年、自動車の高性能化とともに、各種の制御回路の
増加など自動車内における配線箇所は多く、またそれら

エネルギの立場などからは、自動車重量の軽量化が強く
要求されるようになってきた。[Related Art] In recent years, with increasing performance of automobiles, there are many wiring locations in automobiles, such as an increase in various control circuits, and the reliability required for them has been further strengthened. On the other hand, from the standpoint of energy saving, it has been strongly required to reduce the weight of automobiles.

縁体を同心円状に被覆して電線としていた。Conventionally, JIS C 31
A soft copper wire as specified in 02 or a twisted wire obtained by twisting a tinned wire or the like is used, and this is concentrically covered with an insulator such as vinyl chloride, cross-linked vinyl or cross-linked polyethylene. And electric wires.
ところで自動車配線回路では、前述のとおり近年特に
制御用などの信号電流回路の割合が増加している。この
ような電線では、通電容量には十分余裕があるにもかか
わらず、機械的強度維持のために電気的な必要径より大
なる導体を用いていた。By the way, in automobile wiring circuits, as described above, in recent years, the ratio of signal current circuits especially for control has increased. In such an electric wire, a conductor having a diameter larger than an electrical required diameter has been used to maintain mechanical strength, although there is a sufficient margin in the current carrying capacity.
このような電線を軽量化する試みとして、導体のアル
ミニウム（合金を含む、以下同じ）化も一部検討され
た。As an attempt to reduce the weight of such electric wires, some attempts have been made to make the conductor aluminum (including an alloy, the same applies hereinafter).
［発明が解決しようとする課題］ しかしながら、アルミニウムでは一般に強度的に弱
く、十分な強度を得るためには外径を太くするとか、撚
線本数を多くするとかの方策が必要となり、絶縁体を多
く必要とすることにより、配線スペースを多く必要とす
るほか、軽量化の効果も十分に期待できず、また絶縁体
コストの上昇をも招く効果となりやすかった。[Problems to be Solved by the Invention] However, aluminum is generally weak in strength, and in order to obtain sufficient strength, it is necessary to take measures such as increasing the outer diameter or increasing the number of twisted wires. The need for a large amount requires a large amount of wiring space, and the effect of reducing the weight cannot be sufficiently expected, and the effect of increasing the cost of the insulator is likely to be obtained.
この発明の目的は、細径化、すなわち軽量化しても従
来のハーネス電線に劣らない破断荷重を有し、さらに衝
撃的な荷重に対しても破断しにくく、また線ぐせが悪く
なく、切断した撚線にバラケがないハーネス用電線導体
を提供することにある。The object of the present invention is to reduce the diameter, that is, to have a breaking load that is not inferior to the conventional harness electric wire even when the weight is reduced, and it is also difficult to break even under an impact load, and the wire is not bad and cut. An object of the present invention is to provide a harness electric wire conductor in which stranded wires have no variation.
［課題を解決するための手段および作用］ この発明のハーネス用電線導体は、導体断面積が0.03
〜0.3mm2であって、Snを0.2〜2.5重量％含み、残部が本
質的に銅よりなる、断面円形形状の素線を撚り合わせて
撚線とし、この撚線を円型圧縮加工したことを特徴とし
ている。[Means and Actions for Solving the Problems] The harness electric wire conductor of the present invention has a conductor cross-sectional area of 0.03.
A ～0.3Mm 2, includes Sn 0.2 to 2.5 wt%, the balance of essentially of copper, and circular cross section shape wire twisted together twisted wire, that the stranded wire was processed circular compression It is characterized by.
この発明において、導体断面積を0.03〜0.3mm2とした
のは、0.03mm2未満であれば、ハーネスとしての加圧の
際端子圧縮加工が困難であり、0.3mm2を越えれば、軽量
化の目的にそぐわないからである。In the present invention, the conductor cross-sectional area was 0.03 to 0.3 mm 2, if it is less than 0.03 mm 2, terminal compression processing upon pressurization of the harness it is difficult, if exceeds the 0.3 mm 2, weight This is because it does not fit the purpose.
この発明において、Snの含有量を0.2〜2.5重量％とし
ているのは、Snが0.2重量％より少なくなると、破断荷
重の向上の効果が少なくなり、2.5重量％より多くなる
と、導電率が50％以下になってしまうため、電線として
回路によっては望ましくない場合が生じるからである。In the present invention, the content of Sn is set to 0.2 to 2.5% by weight. When the content of Sn is less than 0.2% by weight, the effect of improving the breaking load is reduced, and when the content is more than 2.5% by weight, the conductivity is 50%. This is because, due to the following, an undesirable case may occur depending on the circuit as the electric wire.
また、この発明のハーネス用電線導体において、単線
ではなく、撚線としているのは、繰返し屈曲に対して信
頼性を高めるためである。The harness electric wire conductor according to the present invention is not a single wire but a stranded wire in order to increase reliability against repeated bending.
また、この発明では、撚線を円型圧縮加工している。
第１図は、この発明の一実施例を示す断面図であり、第
２図は、従来のハーネス電線を示す断面図である。Further, in the present invention, the stranded wire is subjected to circular compression processing.
FIG. 1 is a sectional view showing an embodiment of the present invention, and FIG. 2 is a sectional view showing a conventional harness electric wire.

The stranded wire 2 is subjected to circular compression processing, and the outer peripheral surface of the element wire 2a located on the outside is subjected to compression processing so as to have a substantially circular shape as a whole. The insulating coating 3 is provided on the outer periphery of the stranded wire 2 which has been subjected to the circular compression processing as described above.

図ることができないという問題を生じる。Referring to FIG. 2, in a conventional harness electric wire 11, an insulating coating 13 is formed around a stranded wire 12 obtained by simply twisting strands, and the insulating coating 13 extends to a groove 14 between the strands 12a. Was provided. The groove 14 between the strands is a portion that does not affect the insulation even if the insulating film 13 is not provided.By providing the insulating film 13 also in such a portion, a large amount of material of the insulating film is required, A problem arises in that the weight cannot be sufficiently reduced from the viewpoint of weight.

なく、また軽量化を達成することができる。On the other hand, in the case of the harness electric wire 1 according to the present invention as shown in FIG. 1, since a very large groove is not formed between the strands 2a, a large amount of coating material is not required and the weight is light. Can be achieved.
また、この発明に従うハーネス用電線では、同一の断
面積で見た場合、隙間の部分が少ないので、外径を小さ
くすることができ、細径化を図ることができる。Further, in the harness electric wire according to the present invention, when viewed from the same cross-sectional area, since there are few gaps, the outer diameter can be reduced, and the diameter can be reduced.

工により、線ぐせを改善することができる。Further, copper used for the harness electric wire conductor according to the present invention contains 0.2 to 2.5% by weight of Sn, and has a spring property as compared with conventionally used soft copper, so that the terminal is easily separated, It is conceivable that a problem that it is difficult to crimp the terminal fitting is caused. However, in the present invention,
Since the stranded wire is subjected to the circular compression processing, it is possible to reduce the occurrence of such terminal deviation. In addition, the roundness can be improved by the circular compression processing.
さらに、円型圧縮加工することにより耐衝撃力も改善
されるということを見出した。Further, they have found that the impact resistance can be improved by the circular compression processing.
また、この発明に従うハーネス用電線においては、円

10分以上の熱処理したものであることを特徴としてい
る。Further, in the harness electric wire according to the present invention, the circularly-compressed stranded wire is subjected to a temperature in the range of 180 ° C to 350 ° C.
It is characterized by being heat-treated for 10 minutes or more.
熱処理温度を180℃〜350℃の範囲内とするのは、180
℃未満の場合には、衝撃値を向上させるという効果が十
分でない場合があり、一方、350℃より高い温度になる
と、著しく破断荷重が低下してしまう場合があるからで
ある。The heat treatment temperature within the range of 180 ° C to 350 ° C
If the temperature is lower than 0 ° C, the effect of improving the impact value may not be sufficient, while if the temperature is higher than 350 ° C, the breaking load may be significantly reduced.
また、熱処理時間を10分以上とするのは、10分未満と
なると、衝撃値を向上させるという効果が不十分な場合
があるからである。The reason why the heat treatment time is set to 10 minutes or more is that if the heat treatment time is less than 10 minutes, the effect of improving the impact value may be insufficient.
このような熱処理をすることにより、引っ張り強さが
熱処理前の80〜95％の範囲内となるような熱処理が行な
われることになる。その結果、耐衝撃力をさらに向上さ
せることができ、かつ撚線のばらけをさらに少なくする
ことができる。By performing such a heat treatment, a heat treatment is performed such that the tensile strength is in the range of 80 to 95% of that before the heat treatment. As a result, the impact resistance can be further improved, and the variation of the stranded wire can be further reduced.
なお、この熱処理により引っ張り強さにおける破断荷
重は低下するが、この低下した破断荷重を、上記のよう

題を生じることがある。また、引っ張り強さが熱処理前
の80％より低くなる場合には、破断荷重が著しく低下し
てしまい、Snを所定量含有させて破断強度を向上させる
という合金化の効果が失われてしまう。Although the heat treatment reduces the breaking load in the tensile strength, it is preferable that the reduced breaking load be in the range of 80 to 95% before the heat treatment as described above. If the breaking load after the heat treatment is larger than 95% before the heat treatment, the impact value may not be sufficiently improved, which may cause a problem such as unevenness or line breaking. If the tensile strength is lower than 80% before the heat treatment, the breaking load is significantly reduced, and the alloying effect of improving the breaking strength by including a predetermined amount of Sn is lost.
