【発明の詳細な説明】
〔産業上の利用分野〕
この発明は、曲げ応力、ねじり応力、引張り応力と言っ
た力に対する耐性を改善した高強度導体に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates to a high-strength conductor with improved resistance to forces such as bending stress, torsional stress, and tensile stress.
可動体相互間又は固定体と可動体間を結ぶ導電線は、曲

較的可撓性に富む線の単体や撚り合せ集合線に絶縁処理
を施すなどしたものが用いられている。Conductive wires connecting movable bodies or between a fixed body and a movable body are often repeatedly subjected to bending, torsion stress, or tensile stress. Therefore, conductive wires for such uses include relatively flexible single wires such as copper wires, copper alloy wires, or thin copper-plated iron wires, or wires made by applying insulation treatment to twisted and assembled wires. is used.
しかしながら、それ等の導電線は、主体となる銅や鉄の
強度自体に問題があるため、耐屈曲寿命が決して良いと
は言えず、最近富に需要の増えている各種のロボット、
医療機器、精密電子機器、0Afi器等のように頻繁に
動きを生じる装置の変位点間を結ぶ電気回路には、疲労
が激しくて、早期破断を起こすことがある。However, these conductive wires have problems with the strength of the copper and iron that make up the main components, so they cannot be said to have a good bending life.
Electrical circuits that connect displacement points of devices that frequently move, such as medical equipment, precision electronic equipment, and 0Afi equipment, are subject to severe fatigue and may cause premature breakage.
そこで、この発明は、繰り返し応力や伸び変形に充分に
耐える屈曲寿命に優れた高強度導体々を提供することを
目的としている。Therefore, an object of the present invention is to provide high-strength conductors that can sufficiently withstand repeated stress and elongation deformation and have an excellent bending life.
上記の目的を達成するため、この発明では補強用芯材と

設けたこきに特徴づけられるのが、この発明の高強度導
体である。本用途では高周波電流を流して実用されるが
、高周波電流は導体の表面を流れるため、導電性の良好
な銅又は銅合金を被覆材としたのである。In order to achieve the above object, the present invention employs an austenitic stainless steel wire with a good balance of strength and elongation as a reinforcing core material, and coats the outer periphery of the wire with a conductive material. Specifically, as shown in Figure 1, the wire diameter is 0.01
A wire with a cross-sectional area ratio of 5% or more 7 on the outer periphery of the core austenitic stainless steel wire 1 with a diameter of 1 mm or more and 0.7 mm or less
The high-strength conductor of the present invention is characterized by having a coating layer 2 made of 0% or less copper or an alloy thereof. In this application, a high-frequency current is passed through the conductor, and since the high-frequency current flows on the surface of the conductor, copper or a copper alloy with good conductivity was used as the coating material.
更に銅又は銅合金はオーステナイト系ステンレス鋼に比
べれば加工硬化しにくく柔らかいので、本用途で次に重
要な特性であるしなやかさを得るためには外層に用いな
ければならない。Furthermore, copper or copper alloys are less susceptible to work hardening and are softer than austenitic stainless steels, so they must be used in the outer layer in order to obtain flexibility, which is the next most important property in this application.
又ここで芯材にオーステナイト系ステンレス鋼を用いた
のは、フェライト系、マルテンサイト系、析出硬化型の
ステンレス鋼や鉄、鋼糸の材料では引張強度と伸びのバ

特性の劣るステンレスを芯に用いることは、−見ナンセ
ンスのように見えるが、これが本発明の最大のPa1n
tである。In addition, austenitic stainless steel was used as the core material because ferritic, martensitic, precipitation-hardened stainless steel, iron, and steel thread materials have a poor balance of tensile strength and elongation, so it is difficult to use as a substitute for this purpose. This is because the bending value, which is a characteristic, becomes low. It may seem nonsense to use stainless steel, which has good corrosion resistance but generally has inferior mechanical properties than steel, for the core, but this is the biggest advantage of the present invention.
It is t.
ここで、この発明の導体において、芯材となるステンレ
ス!7!I線の線径を上述の値に限定したのは、その線
径が0.011mmφ以下では強度的に優れるステンレ
スであっても、破断力が10g以下となって僅かな力で
断線するため実用に耐えず、一方、0.7mmφ以上で
は、破断力が20kg以上となり、線が硬すぎてしなや
かさの要求される精密電子機器用としては扱い難くなる
からである。Here, in the conductor of this invention, stainless steel is the core material! 7! The reason why the wire diameter of the I wire is limited to the above value is that even if the wire diameter is 0.011 mmφ or less, even stainless steel has excellent strength, the breaking force will be less than 10 g, and it will break with a slight force, so it is not practical. On the other hand, if the diameter is 0.7 mm or more, the breaking force will be 20 kg or more, and the wire will be too hard to handle for precision electronic devices that require flexibility.
また、被覆層の断面積比も、5%以下では、電子ワイヤ
に要求される導電特性を満足し得す、70%以上ではス
テンレス電線による補強効果が充分に得られないからで
ある。Further, if the cross-sectional area ratio of the coating layer is 5% or less, the electrical conductivity required for the electronic wire can be satisfied, but if it is 70% or more, the reinforcing effect of the stainless steel wire cannot be sufficiently obtained.
なお、被覆層2は、周知のメツキ法やクラッド法等によ
って形成すればよい。Note that the covering layer 2 may be formed by a well-known plating method, cladding method, or the like.
また、その層2の形成時期は、ステンレス鋼線1を先に
述べた径になる迄伸線した後、又は伸線前のいずれであ
ってもよい。Further, the layer 2 may be formed either after the stainless steel wire 1 is drawn to the diameter described above or before the wire drawing.
なお本用途の機械的特性の中で最も重要なのは耐屈曲寿
命であるが、耐屈曲寿命特性の加速試験としては第2図
に示すように、R= 0.4mmの円弧面に沿わせて線
材を(イ)→(r+)→(ハ)の順に屈曲させる90°
曲げ値で評価する屈曲試験が用いられる。The most important mechanical property for this application is the bending life, but as shown in Figure 2, as an accelerated test of the bending life, the wire was 90° bending in the order of (a) → (r+) → (c)
A bending test is used that evaluates by bending value.
しかしこの屈曲値は同じ素材でも荷重の重さと線径によ
り大きく異なるので単純にその大小で評価できない。However, this bending value cannot be evaluated simply by its size, as it varies greatly depending on the weight of the load and the wire diameter even for the same material.
そこで我々は(引張強度(kg/mm2)) x (伸
び(%))なる指!(TP)を導入すれば荷重の重さや
線径が異ってもその値の大小で屈曲値の良否すなわち精
密電子機器用電線としての屈曲寿命の長短を評価できる
ことを見出した。この指標は引張強度と伸びという互い
に相反するものであるが、その積をとることにより”°
しなやかさ°′を一軸で評価できるという利点がある。So we have a finger that is (tensile strength (kg/mm2)) x (elongation (%))! It has been found that by introducing (TP), it is possible to evaluate the quality of the bending value, that is, the length of the bending life as an electric wire for precision electronic equipment, by the magnitude of the value even if the weight of the load and the wire diameter are different. This index is tensile strength and elongation, which are contradictory to each other, but by taking the product of
It has the advantage of being able to evaluate suppleness °′ on a single axis.

たメツシュ導体等を最終製品として実用に供すればよい
。In addition, the high-strength conductor of the present invention may be put to practical use as a final product, such as a solid wire, a flammable wire, a wire with an insulating coating applied to the outer periphery of the wire, or a mesh conductor formed by knitting bare wires.

トも生まれる。As can be seen from this table, the conductivity of the conductor of the present invention changes depending on the cross-sectional area ratio of the coating layer (the sample is copper), and although it is smaller than that of well-known copper-based conductors, it is In the case of conductive wires for electronic devices, since large currents do not flow, sufficient conductive performance can be ensured as a conductive material for such applications. On the other hand, when used as a high-frequency conductor, since the outer periphery is made of copper or aluminum, it can be expected that the performance will actually exceed the overall average conductivity, and the conductivity can be increased by changing the cross-sectional bond ratio. There is also the advantage of being able to control it.

覆なまし鉄線等に比較してはるかに優れる。In addition, since the stainless steel wire is used as the core material, the tensile strength is about three times higher than that of copper-based materials (close to the drawn copper-clad stainless steel wire in ■), and the elongation is also lower than that of copper-based materials and copper-clad stainless steel wire. Much superior to annealed iron wire, etc.
さらに、屈曲値は首記のロボット等に採用する場合、最
も重要視されるが、この発明の導体は、従来のそれと比
較にならない程優れた特性を示している。Furthermore, the bending value is considered most important when used in the above-mentioned robots, and the conductor of the present invention exhibits characteristics that are incomparably superior to those of conventional conductors.
なお比較例[相]ではTP値は744とかなり良い数値
を示しているが屈曲値はそれ程良くない。In Comparative Example [Phase], the TP value is 744, which is a fairly good value, but the bending value is not so good.
やはり芯材はオーステナイト系ステンレスwJ線を用い
なければ本用途を満足させることはできない。After all, this application cannot be satisfied unless an austenitic stainless steel wJ wire is used as the core material.
第3図には0.1+nn+φのオーステナイト系ステン

800以上で屈曲値が優れるのがわかる。FIG. 3 shows the relationship between the TP value and the bending value of 0.1+nn+φ austenitic stainless steel wire and copper wire, and it can be seen that the bending value is excellent when the TP value is 800 or more.
以上述べたように、この発明の高強度導体は、線径及び

又はその合金を特定された断面猜比の範囲で被覆したも

求値を充分に確保し得る。増強効果は、勿論、ステンレ
スの特性によるものである。As described above, the high-strength conductor of the present invention includes copper, copper,
Alternatively, since the alloy is coated with a specified cross-sectional ratio range, the strength can be greatly improved, and the required conductivity can be sufficiently ensured. The reinforcing effect is, of course, due to the properties of stainless steel.
また、銅合金は、元来伸びが小さい上、高強度を得るの
に必要な冷間加工により、その伸びが著しく小さくなる
。これに対し、ステンレスは本来、高強度で焼鈍状態で
利用できるため、大きな伸びを確保できる。In addition, copper alloys inherently have low elongation, and the cold working necessary to obtain high strength significantly reduces their elongation. On the other hand, stainless steel inherently has high strength and can be used in an annealed state, so it can ensure large elongation.
さらに、ステンレスの特性により、耐疲労性、屈曲性能
も大巾に向上する。Furthermore, due to the characteristics of stainless steel, fatigue resistance and bending performance are greatly improved.
そのほか、ステンレスと被覆属の断面積比を限定値内で
自由に選べるので、導電率のコントロールも可能になる
と云う効果が得られる。In addition, since the cross-sectional area ratio of the stainless steel and the coating metal can be freely selected within a limited value, it is possible to control the electrical conductivity.
また、この発明の方法によれば、被ff1層形成後に伸

、極細の線に対してもクラッド法の適用が可能になる。Further, according to the method of the present invention, since the wire drawing process is performed after the formation of the first ff layer, the coating efficiency can be increased, and furthermore, the cladding method can be applied to extremely fine wires.
