本考案は、油や酸・アルカリ溶剤などの薬品が付着するおそれがあり、ケーブ ルの絶縁線心相互またはケーブルとケーブルベアとの接触などによる絶縁体・シ ース等の摩耗のおそれのある条件下で使用されるロボット用ケーブル、センサー 用リード線などに用いられる耐油・耐薬品・耐摩耗・耐屈曲・可撓性ケーブルに 関するものである。 This invention has the risk of being contaminated with chemicals such as oil, acids, and alkaline solvents. Insulators and shields due to contact between insulated wire cores of cables or contact between cables and cable carriers, etc. Cables and sensors for robots used under conditions where there is a risk of wear such as For oil-resistant, chemical-resistant, abrasion-resistant, bend-resistant, and flexible cables used in lead wires, etc. It is related to
【０００２】0002
従来、化学工場、塗装工場において使用される移動用ケーブル、ロボット用ケ ーブル、センサー用リード線として、耐油性・耐薬品性にすぐれたフッ素樹脂を シースとして用いた耐油・耐薬品性ケーブルが用いられている。 Traditionally, mobile cables and robot cages used in chemical factories and paint factories. We use fluororesin, which has excellent oil and chemical resistance, as lead wires for cables and sensors. An oil- and chemical-resistant cable used as a sheath is used.
【０００３】0003
しかし、フッ素樹脂は一般に硬くて剛性が大きいので、ケーブルシースとして 用いた場合は、可撓性を損なうという問題がある。そこで、本考案者らは、導体 上に被覆する絶縁体のみをフッ素樹脂とし、シースを軟らかいフッ素樹脂エラス トマーで形成した耐油・耐薬品・可撓性ケーブルを提案した。しかし、ロボット 用ケーブル等においては、ロボットまたは機器の運動や移動に伴って、ケーブル とケーブルベア等の他の物体との接触・摩擦やケーブルの絶縁線心相互の接触・ 摩擦が生じるような条件下で使用されることが多く、その点ではフッ素樹脂エラ ストマーは十分な耐摩耗性を有するとはいえないという問題点がある。 However, fluororesin is generally hard and has high rigidity, so it cannot be used as a cable sheath. If used, there is a problem of loss of flexibility. Therefore, the inventors of the present invention Only the insulation covering the top is made of fluororesin, and the sheath is made of soft fluororesin elastomer. We proposed an oil-resistant, chemical-resistant, and flexible cable made of Tomer. But the robot cables, etc., due to movement or movement of the robot or equipment. contact/friction with other objects such as cable carriers, contact/friction between insulated cores of cables, etc. It is often used under conditions where friction occurs, and in this respect fluororesin elastomers There is a problem that the stomer cannot be said to have sufficient wear resistance.
【０００４】 また、摩擦によって静電気が発生するため、静電気を帯びたケーブルが金属体 などに接近したとき放電を生じることがあり、可燃性または爆発性雰囲気中では 、発火や爆発の危険性もある。そこで、シースを導電性にすることにより、帯電 を防止することが考えられるが、万一導体の素線切れが生じ絶縁を突き破ってシ ースにその導体素線が接触すると危険である。0004 Also, because static electricity is generated by friction, cables that are charged with static electricity may not be connected to metal objects. Electric discharge may occur when approaching , there is also a risk of fire or explosion. Therefore, by making the sheath conductive, it is possible to However, in the unlikely event that the conductor strands break and break through the insulation, the It is dangerous if the conductor wire comes into contact with the ground.
【０００５】 本考案は、上述した問題点に鑑みてなされたものであり、その目的とするとこ ろは、第１に、耐油・耐薬品・可撓性のみならず、耐摩耗性にもすぐれたケーブ ルを提供せんとするものである。第２に、シースが導電性を有する場合に導体素 線切れが生じても安全なケーブルを提供せんとするものである。第３に、耐屈曲 性にすぐれ、導体素線切れのおそれのきわめて少ないケーブルを提供せんとする ものである。[0005] The present invention was developed in view of the above-mentioned problems, and its purpose is to Firstly, the cable is not only oil resistant, chemical resistant, flexible, but also has excellent abrasion resistance. The aim is to provide the following information. Second, if the sheath has conductivity, the conductor element The aim is to provide a cable that is safe even if wire breaks occur. Third, bending resistance We aim to provide cables with excellent performance and extremely low risk of breaking conductor wires. It is something.

上記目的を達成するために、本考案における耐油・耐薬品・耐摩耗・耐屈曲・ 可撓性ケーブルは、導体上にフッ素樹脂を被覆して成る絶縁線心を有するケーブ ルコアの外方に、フッ素樹脂エラストマーから成る内部シース、ポリウレタンエ ラストマーから成る外部シースを備えたものである。 In order to achieve the above purpose, the present invention has been designed to be oil resistant, chemical resistant, abrasion resistant, bend resistant, A flexible cable is a cable with an insulated core made of a fluororesin coating on the conductor. On the outside of the Lucoa, there is an inner sheath made of fluoropolymer elastomer, a polyurethane It has an outer sheath made of lastomer.
【０００７】 そして、導体の全部又は一部が少なくともＺｒを含む添加元素の総量が０．０ ０５〜０．５重量％である銅合金であって、最終線径細線に至る中間線径で中間 熱処理を施してＣｕ3 Ｚｒを析出させて成る高力高導電性銅合金の細線を素線と する撚線導体から成るものである。さらに、上記銅合金から成る銅合金箔テープ を高抗張力繊維糸の周りに横巻きして形成した銅合金箔糸を素線とする撚線導体 から成るものである。[0007] All or part of the conductor is made of a copper alloy in which the total amount of additive elements including at least Zr is 0.005 to 0.5% by weight, and the conductor is made of a copper alloy having an intermediate wire diameter leading to a final wire diameter fine wire. It consists of a stranded wire conductor whose strands are fine wires made of a high-strength, high-conductivity copper alloy that has been heat-treated to precipitate Cu 3 Zr. Further, it is made of a stranded wire conductor whose strands are copper alloy foil threads formed by horizontally winding a copper alloy foil tape made of the above-mentioned copper alloy around high tensile strength fiber threads.

内部シースを耐油性・耐薬品性・可撓性にすぐれたフッ素樹脂エラストマーと し、外部シースを耐摩耗性にすぐれたフッ素樹脂エラストマーで形成したので、 ケーブル全体として、耐油性・耐薬品性・可撓性を損なうことなく耐摩耗性も良 くなる。 The inner sheath is made of fluororesin elastomer with excellent oil resistance, chemical resistance, and flexibility. However, the outer sheath is made of fluororesin elastomer with excellent wear resistance. The cable as a whole has good abrasion resistance without sacrificing oil resistance, chemical resistance, or flexibility. It becomes.
【０００９】 そして、導体の全部又は一部を構成する素線が少なくともＺｒを含む添加元素 の総量が０．００５〜０．５重量％である銅合金であって、最終線径細線に至る 中間線径で中間熱処理を施してＣｕ3 Ｚｒを析出させた高力高導電性銅合金細線 から成るので、耐屈曲性にすぐれている。なお、この高力高導電性銅合金は特願 平２−３０５６４８号の明細書に記載のとおり、耐屈曲性・引張強さなどの機械 的強度にすぐれ、しかも、導電率の高い銅合金である。Ｚｒを含む添加元素の総 量が０．００５重量％未満であると機械的強度が向上せず、０．５重量％を越え ると、導電率及び線引加工性が悪くなる。また、中間線径で中間熱処理を施した 後冷間伸線した場合にはＺｒの析出量が増加する結果、Ｃｕ3 Ｚｒが析出し、銅 マトリックス中の加工歪が取り除かれることになり、導電率及び機械的強度を向 上させる。[0009] The strands constituting all or a part of the conductor are made of a copper alloy in which the total amount of additive elements including at least Zr is 0.005 to 0.5% by weight, and the wire is an intermediate wire constituting the final wire with a fine diameter. Since it is made of a high-strength, high-conductivity copper alloy fine wire that has been subjected to intermediate heat treatment to precipitate Cu 3 Zr, it has excellent bending resistance. As described in the specification of Japanese Patent Application No. 2-305648, this high-strength, high-conductivity copper alloy has excellent mechanical strength such as bending resistance and tensile strength, and is also a high-conductivity copper alloy. be. If the total amount of additional elements including Zr is less than 0.005% by weight, mechanical strength will not improve, and if it exceeds 0.5% by weight, electrical conductivity and wire drawability will deteriorate. In addition, when cold wire is drawn after intermediate heat treatment at an intermediate wire diameter, the amount of Zr precipitated increases, resulting in the precipitation of Cu 3 Zr, which removes the processing strain in the copper matrix and improves conductivity. rate and mechanical strength.
【００１０】 しかも、外部シースの内側に内部シースがあるので、外部シースを半導電性ポ リウレタンエラストマーとした場合において、万一導体の素線切れが生じても直 ちにそれが半導電性ポリウレタンエラストマーの外部シースと接触せず、地絡の おそれもない。さらに、導体の全部又は一部を上記銅合金細線を箔状にして高抗 張力繊維糸の周りに横巻きして形成した銅合金箔糸を素線として構成するときは 、銅合金箔糸がケーブル屈曲時の各心線の伸縮に対応して伸び縮みし、かつ高抗 張力繊維糸の特性と相俟って銅合金細線そのものを素線として構成したものより も耐屈曲性がさらにすぐれたものとなり、万一素線切れが生じても、素線自体の 剛性が小さいので、内部シースを突き抜ける危険性はない。0010 Moreover, since the inner sheath is inside the outer sheath, the outer sheath can be When using urethane elastomer, even if a conductor strand breaks, it will not be damaged immediately. If it does not come into contact with the semiconductive polyurethane elastomer outer sheath, it will cause a ground fault. There's no fear. Furthermore, all or part of the conductor is made of the above-mentioned copper alloy thin wire in the form of a high-resistance foil. When configuring copper alloy foil threads formed by horizontally wrapping them around tension fiber threads as strands, , the copper alloy foil thread expands and contracts in response to the expansion and contraction of each core wire when the cable is bent, and has high resistance. Coupled with the properties of tensile fiber yarn, it is better than one made of copper alloy fine wire itself as a strand. The bending resistance is even better, and even if the wire breaks, the wire itself will not break. Due to its low rigidity, there is no risk of it penetrating the inner sheath.

以下、本考案の実施例を図面を参照しつつ説明する。図１は考案例１及び２の ケーブルの断面図を示している。 Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows design examples 1 and 2. Figure 3 shows a cross-sectional view of the cable.
【００１２】 導体１を被覆する絶縁体２で一つの絶縁線心３Ａとなり、４本の絶縁線心３Ａ ，３Ｂ，３Ｃ，３Ｄと、その間の介在物４及び押え巻きテープ５でケーブルコア ６が形成されている。0012 Insulator 2 covering conductor 1 forms one insulated wire core 3A, and four insulated wire cores 3A , 3B, 3C, 3D, the inclusion 4 between them, and the pressing tape 5 to form the cable core. 6 is formed.
【００１３】 考案例１及び２共に、導体１は特願平３−３０５６４８号に記載の高力高導電 性銅合金の細線から成る撚線導体２．０ｍｍ2 （７／５７／０．０８ｍｍ）×４ Ｃであり、導体１上の絶縁体２はフッ素樹脂のＥＴＦＥ（テトラフルオロエチレ ン、エチレン共重合体）である。絶縁体２をフッ素樹脂としたのは、電気特性が 良く絶縁厚さを薄くすることができ、ケーブル外径を小さくすることができるか らである。特に、ＥＴＦＥは耐摩耗性が良いので、ケーブル屈曲時の絶縁線心同 士の摩擦に耐え、ロボット用ケーブル等の用途に適している。In both Examples 1 and 2, the conductor 1 is a 2.0 mm 2 (7/57/0.08 mm) stranded conductor made of fine wires of high-strength, high-conductivity copper alloy described in Japanese Patent Application No. 3-305648. ×4 C, and the insulator 2 on the conductor 1 is a fluororesin ETFE (tetrafluoroethylene, ethylene copolymer). The reason why the insulator 2 is made of fluororesin is that it has good electrical properties, allows the insulation thickness to be reduced, and allows the cable outer diameter to be reduced. In particular, ETFE has good wear resistance, so it can withstand friction between insulated wire cores when the cable is bent, making it suitable for applications such as robot cables.
【００１４】 そして、考案例１及び２共に、内部シース８にはフッ素樹脂エラストマーが用 いられているが、考案例１の外部シース９にはポリウレタンエラストマーが用い られ、考案例２の外部シース９′には導電性ポリウレタンエラストマーが用いら れている。このフッ素樹脂エラストマー及びポリウレタンエラストマーは可撓性 にすぐれた材料であるが、ＪＩＳＫ３６０１に規定されたスプリング硬さ試験（ Ａ形）による硬度が８５以下のもの、さらには７０以上８０以下のものが好まし い。また、フッ素樹脂エラストマー及びポリウレタンエラストマーは共に耐油性 ・耐薬品性にもすぐれており、特にポリウレタンエラストマーは耐摩耗性にすぐ れている。したがって、ケーブルとケーブルベア等の他の物体との接触・摩擦が 生じるような条件下で使用されるロボット用ケーブル、センサー用リード線等の 用途に適している。さらに、いずれの材料も、内部シース８、外部シース９の成 形に際して、加硫工程がないので、製造が容易である。しかも導体が高力高導電 性銅合金を素線とする撚線導体であるから耐屈曲性にすぐれ素線切れのおそれが きわめて少ない。[0014] In both design examples 1 and 2, fluororesin elastomer is used for the inner sheath 8. However, the outer sheath 9 of Example 1 is made of polyurethane elastomer. The outer sheath 9' of Example 2 is made of conductive polyurethane elastomer. It is. This fluororesin elastomer and polyurethane elastomer are flexible Although it is an excellent material, it has not been tested in the spring hardness test specified in JISK3601 ( Type A) hardness is preferably 85 or less, more preferably 70 or more and 80 or less. stomach. In addition, both fluororesin elastomer and polyurethane elastomer are oil resistant. ・It also has excellent chemical resistance, and polyurethane elastomer in particular has excellent abrasion resistance. It is. Therefore, contact and friction between the cable and other objects such as cable carriers is reduced. robot cables, sensor lead wires, etc. that are used under such conditions. suitable for the purpose. Furthermore, both materials are suitable for forming the inner sheath 8 and outer sheath 9. Since there is no vulcanization process in shaping, manufacturing is easy. Moreover, the conductor has high strength and high conductivity. Because it is a stranded wire conductor whose wires are made of copper alloy, it has excellent bending resistance and there is no risk of wire breakage. Very few.
【００１５】 考案例２の外部シース９′に用いられる導電性ポリウレタンエラストマーは、 ポリウレタンエラストマーにカーボンを配合して体積抵抗率を１０8 Ω−ｃｍ以 下としたものである。このものは、ケーブルとケーブルベア等の他の物体との摩 擦によって静電気を帯びることがなく、したがってスパーク発生の恐れがないの で、可燃性または爆発性雰囲気中でも使用できる。しかも、外部シース９′の内 側には内部シース８があるので、万一絶縁線心の素線切れが生じても直ちにそれ が半導電性ポリウレタンエラストマーの外部シース９′と接触することはなく、 したがって地絡のおそれもない。The conductive polyurethane elastomer used for the outer sheath 9' of Example 2 is a polyurethane elastomer mixed with carbon to have a volume resistivity of 10 8 Ω-cm or less. This cable is not charged with static electricity due to friction between the cable and other objects such as cable carriers, and therefore there is no risk of spark generation, so it can be used even in flammable or explosive atmospheres. Furthermore, since the inner sheath 8 is located inside the outer sheath 9', even if a strand of the insulated wire core should break, it will not immediately come into contact with the outer sheath 9' made of semiconductive polyurethane elastomer. Therefore, there is no risk of ground fault.

It has good abrasion resistance and bending resistance without compromising oil resistance, chemical resistance, and flexibility. Excellent. In addition, there is no risk of the cable being charged with static electricity due to friction. In the unlikely event that a conductor strand breaks, it is immediately removed from the semiconductive polyurethane elastomer. No contact with the sheath, and there is no risk of ground fault.

Although a composite stranded conductor is used, other stranded conductors such as a collective stranded conductor may be used. Also, Conductors 1 and 14 are copper alloy foil threads in which copper alloy foil tape is wound horizontally around high tensile strength fiber threads. If the wire is used as a stranded conductor to form a twisted wire conductor, the bending resistance will be even better.
【００１８】 例えば、上記図２の考案例において、図３（ａ）のように導体１４を銅合金箔 糸３１を７本撚り合わせた撚線導体とする。ここで、図３（ｂ）のように銅合金 箔糸３１は、２５０デニールのテトロン糸３２の周りに、箔厚０．０２７ｍｍ、 箔幅０．３２ｍｍの銅合金箔３３を１０ｍｍあたり２２回の密度で横巻きした構 造である。この導体１４の断面積は上記すずメッキ軟銅より線（０．２ｍｍ2 ） よりも小さいが耐屈曲性はすずメッキ軟銅より線よりすぐれており、図２の導体 １１の撚線導体（０．５ｍｍ2 ）よりも断面積の小さい導体１４の方が先に断線 するということを防止できる。For example, in the example shown in FIG. 2, the conductor 14 is a stranded conductor made by twisting seven copper alloy foil threads 31 as shown in FIG. 3(a). Here, as shown in FIG. 3(b), the copper alloy foil thread 31 is made by wrapping a copper alloy foil 33 with a foil thickness of 0.027 mm and a foil width of 0.32 mm 22 times per 10 mm around a 250 denier Tetron thread 32. It has a horizontally wound structure with density. Although the cross-sectional area of the conductor 14 is smaller than that of the tin-plated annealed copper wire (0.2 mm 2 ), its bending resistance is superior to that of the tin-plated annealed copper wire (0.5 mm 2 ). 2 ) It is possible to prevent the conductor 14 having a smaller cross-sectional area from breaking first.

本考案における耐油・耐薬品・耐摩耗・耐屈曲・可撓性ケーブルは、導体上に フッ素樹脂を被覆して成る絶縁線心を有するケーブルコアの外方に、フッ素樹脂 エラストマーから成る内部シース、ポリウレタンエラストマーから成る外部シー スを備えたものであり、内部シースが耐油性・耐薬品性・可撓性にすぐれ、外部 シースが耐摩耗性にすぐれているので、ケーブル全体として、耐油性・耐薬品性 ・可撓性を損なうことなく耐摩耗性を向上させることができる。 The oil-resistant, chemical-resistant, abrasion-resistant, bend-resistant, and flexible cable in this invention is A cable core with an insulated wire core coated with fluororesin is coated with fluororesin on the outside of the cable core. Inner sheath made of elastomer, outer sheath made of polyurethane elastomer The internal sheath has excellent oil resistance, chemical resistance, and flexibility, and the external sheath Since the sheath has excellent abrasion resistance, the entire cable is oil and chemical resistant. ・Abrasion resistance can be improved without compromising flexibility.
【００２０】 そして、導体の全部又は一部を構成する高力高導電性銅合金細線が耐屈曲性に すぐれているため、素線切れを生じるおそれがきわめて少なく、安全である。し かも、外部シースの内側に内部シースがあるので、外部シースを半導電性ポリウ レタンエラストマーとした場合において、万一導体の素線切れが生じても直ちに それが半導電性ポリウレタンエラストマーのシースと接触することがなく、地絡 が発生せず、安全である。さらに導体の全部又は一部を銅合金箔糸を素線として 構成するときは、ケーブルの耐屈曲性が一層すぐれたものとなる。[0020] The high-strength, high-conductivity thin copper alloy wire that makes up all or part of the conductor has excellent bending resistance. Because of its superior properties, there is very little risk of wire breakage, making it safe. death However, since there is an inner sheath inside the outer sheath, the outer sheath can be When using rhethane elastomer, if a conductor strand breaks, immediately It does not come into contact with the semi-conductive polyurethane elastomer sheath and can cause ground faults. It is safe and does not occur. Furthermore, all or part of the conductor is made of copper alloy foil thread as a wire. When configured, the cable has even better bending resistance.
