Description

本発明は、自動車用電線に関し、特に十分な引張強度を有し、細線化、軽量化を図った自動車用電線に関するものである。   The present invention relates to an automobile electric wire, and more particularly to an automobile electric wire having a sufficient tensile strength and reduced in thickness and weight.

自動車では、電装品等への電気的接続のために多数の電線を束ねたワイヤハーネスが使用されている。ワイヤハーネスに使用される電線の導体は、ワイヤハーネスへの加工性から、導体の引張強度が80N程度以上必要で、電線を1本で使用する場合、0.35mm以上の断面積(以下導体サイズとも称する)が必要であった。 In an automobile, a wire harness in which a number of electric wires are bundled is used for electrical connection to an electrical component or the like. The conductor of the electric wire used for the wire harness requires a tensile strength of the conductor of about 80 N or more from the workability to the wire harness, and when using one electric wire, the cross-sectional area of 0.35 mm 2 or more (hereinafter referred to as the conductor) Also referred to as size).

また、ワイヤハーネスに用いられる電線の中には、複数本の素線を撚り合わせた撚線構造の導体を有するものがある。このような導体の一例を図1に示す。図1において1は導体であり、中心素線2の周りに6本の周辺素線3を配置して撚りあわせた撚線構造となっている。従来、このような撚線構造の導体を構成する中心素線2及び周辺素線3にはいずれも銅が使用されているのが一般的であった。   Moreover, some electric wires used for the wire harness have a conductor having a twisted wire structure in which a plurality of strands are twisted together. An example of such a conductor is shown in FIG. In FIG. 1, reference numeral 1 denotes a conductor, which has a twisted wire structure in which six peripheral strands 3 are arranged around a central strand 2 and twisted together. Conventionally, copper has generally been used for the central strand 2 and the peripheral strand 3 constituting such a conductor having a stranded wire structure.

一方、近年の自動車においては、用いられる電線の細線化(例えば導体サイズ0.22mm以下)、軽量化が要求されてきている。ところが、導体(中心素線、周辺素線)に銅を用いたものでは、このような細線化、軽量化を行うと、所要の引張強度を得ることができなくなってしまう。 On the other hand, in recent automobiles, thinning of the electric wires used (for example, conductor size of 0.22 mm 2 or less) and weight reduction have been required. However, in the case where copper is used for the conductor (center strand, peripheral strand), if such thinning and weight reduction are performed, the required tensile strength cannot be obtained.

そこで、これに対して、素線として銅と、ステンレス鋼を用いた複合導体とすることにより、細線化、軽量化を図る提案がなされている(実開平6−13014号公報(特許文献1))。この自動車用電線における導体は、中央素線としてステンレス鋼を用い、その周囲に軟銅からなる複数の周辺素線を配置し、複合撚線構造としたものである。銅に比べてステンレス鋼の方が比重が小さいこと及びステンレス鋼が高い引張強度を有していることにより、細線化、軽量化が図れるようになる。   In view of this, a proposal has been made to reduce the thickness and weight by using a composite conductor using copper and stainless steel as the element wires (Japanese Utility Model Laid-Open No. 6-13014 (Patent Document 1)). ). The conductor in this automobile electric wire has a composite twisted wire structure in which stainless steel is used as a central strand, and a plurality of peripheral strands made of annealed copper are arranged around it. Stainless steel has a lower specific gravity than copper, and stainless steel has a higher tensile strength, so that it is possible to reduce the thickness and weight.

このような構造において、ステンレス鋼からなる素線の伸び率は、例えばSUS304のなまし材では約40%であるのに対し、銅からなる素線の伸び率は、例えば一般的な軟銅材では15%程度と、ステンレス鋼素線の方が銅素線より伸び率が大きくなっているのが実状である。なお、本明細書中「伸び率」とは、引張試験において破断が起こる直前における試験片の長さの増加分を原長の百分率で示したもののことである。
ところが、このような構造の電線では、素線の伸び率はステンレス鋼の方がより大きいため、大きな引っ張り力が加わると、銅素線の方がステンレス鋼素線より先に切断され、電気的にはステンレス鋼素線のみ残ってしまう。ステンレス鋼素線のみが残ると、導体抵抗が大きく、通電時に発熱の可能性がある。
In such a structure, the elongation rate of the strand made of stainless steel is, for example, about 40% in the annealed material of SUS304, whereas the elongation rate of the strand made of copper is, for example, in a general annealed copper material The actual condition is that the elongation of the stainless steel wire is about 15% larger than that of the copper wire. In the present specification, the “elongation rate” refers to an increase in the length of the test piece immediately before breakage in the tensile test, expressed as a percentage of the original length.
However, in the case of an electric wire with such a structure, the elongation rate of the strands of stainless steel is larger than that of copper . Therefore, when a large tensile force is applied, the copper strands are cut before the stainless steel strands. In particular, only the stainless steel wire remains. If only the stainless steel wire remains, the conductor resistance is large and there is a possibility of heat generation when energized.

It becomes.

以下、本発明の実施の形態を好ましい実施例により説明する。   The preferred embodiments of the present invention will be described below.

本発明による第1の自動車用電線(請求項1に相当)は、ステンレス鋼(SUS)からなる中心素線の周囲に該中心素線を包囲するように銅又は銅合金からなる複数の周辺素線を配置してなり、ステンレス鋼からなる素線の伸び率が銅又は銅合金からなる素線の伸び率より小さいことを特徴とする。   A first electric wire for an automobile according to the present invention (corresponding to claim 1) includes a plurality of peripheral elements made of copper or a copper alloy so as to surround the central element wire around a central element wire made of stainless steel (SUS). A wire is arranged, and the elongation rate of the strand made of stainless steel is smaller than the elongation rate of the strand made of copper or a copper alloy.

図2に、第1の自動車用電線の一構成例における導体構成を断面図で示す。図中11は導体の集合体で、ステンレス鋼からなる中心素線12の周囲に、銅又は銅合金からなる6本の周辺素線13が配置され、撚りあわされ撚線構造となっている。また、中心素線12の素線径と周辺素線13の素線径は等しくなっている。この導体の集合体の周りに直接又はシールド層を介して絶縁被覆を設けて、自動車用電線とする。本発明では、ステンレス鋼からなる素線の伸び率が銅又は銅合金からなる素線の伸び率より小さく設定される。ステンレス鋼素線の伸び率は銅又は銅合金素線の伸び率より10〜50%小さいことが好ましい。なお、本明細書において「伸び率」はJIS C 3002に基づくものである。   FIG. 2 is a sectional view showing a conductor configuration in one configuration example of the first automobile electric wire. In the figure, 11 is an assembly of conductors. Six peripheral strands 13 made of copper or copper alloy are arranged around a central strand 12 made of stainless steel, and are twisted to form a stranded wire structure. Moreover, the strand diameter of the center strand 12 and the strand diameter of the peripheral strand 13 are equal. An insulating coating is provided around the conductor assembly directly or through a shield layer to obtain an automobile electric wire. In the present invention, the elongation percentage of the strand made of stainless steel is set smaller than the elongation percentage of the strand made of copper or a copper alloy. The elongation of the stainless steel wire is preferably 10 to 50% smaller than the elongation of the copper or copper alloy wire. In this specification, “elongation rate” is based on JIS C 3002.

本構成例の中心素線12に使用されるステンレス鋼は、上記の条件を満足していることが必要であるが、ステンレス鋼の伸び率の調整方法としては、(1)C成分を増加させる(例えば、SUS304において現行の0.03wt%程度から0.07wt%程度にする)、(2)Ni成分を減少させる(例えば、SUS304において現行の10.0wt%程度から8.0wt%程度にする)、(3)素線製造工程において最終溶体化処理温度を若干下げる(例えば、SUS304において現行の1000〜1200℃を800〜1000℃程度にする)、(4)素線製造工程において最終溶体化処理時間を短くする(例えば、SUS304において現行の5秒をその80%の4秒程度にする)、(5)素線製造工程において最終溶体化処理前の冷間加工度を加工限界ぎりぎり(加工限界に対して95%程度まで上げる、というような方法を用いることができる。これらの方法は単独で用いてもよいし、併用してもよい。
中心素線12の素線径は、用途に応じて適宜設定されるが、通常、0.1〜0.2mm程度とすることが好ましい。
The stainless steel used for the central strand 12 of this configuration example needs to satisfy the above conditions. As a method for adjusting the elongation of the stainless steel, (1) increase the C component. (For example, in SUS304, it is changed from about 0.03 wt% to about 0.07 wt%), (2) Ni component is reduced (for example, in SUS304, from about 10.0 wt% to about 8.0 wt%) ), (3) The final solution treatment temperature is slightly lowered in the strand manufacturing process (for example, the current 1000-1200 ° C. is changed to about 800-1000 ° C. in SUS304), and (4) The final solution treatment is performed in the strand manufacturing process. Reduce the processing time (for example, the current 5 seconds in SUS304 is set to about 80% of 4 seconds) (5) Final solution treatment in the wire manufacturing process Raising the cold working ratio up to about 95% working marginal (processing limit, it is possible to use a method such as that. May be used these methods alone or in combination.
Although the strand diameter of the center strand 12 is suitably set according to a use, it is usually preferable to set it as about 0.1-0.2 mm.

また、周辺素線13に使用される銅又は銅合金は、通常電線に使用される各種のタイプのものが使用できるが、導電性、引張強度、伸び等の観点から純銅、Cu−Ag合金、Cu−Ni−Si合金等の使用が好ましい。周辺素線13の素線径は、用途に応じて適宜設定されるが、通常、0.1〜0.2mm程度である。   Moreover, although the copper or copper alloy used for the peripheral strand 13 can use the various types of thing normally used for an electric wire, from a viewpoint of electroconductivity, tensile strength, elongation, etc., pure copper, Cu-Ag alloy, Use of a Cu-Ni-Si alloy or the like is preferable. Although the strand diameter of the peripheral strand 13 is suitably set according to a use, it is about 0.1-0.2 mm normally.

絶縁被覆としては、従来使用されているポリ塩化ビニル(PVC)、ポリエチレン(発泡系を含む)、ハロゲンフリー材、テトラフロロエチレン等の各種樹脂材料を用いることができる。絶縁被覆の厚さは導体の集合体の外径に応じて適宜設定される。
シールド層を設ける場合には、従来公知のシールド効果を有する各種材料が使用できる。
As the insulating coating, various resin materials such as polyvinyl chloride (PVC), polyethylene (including foamed materials), halogen-free materials, and tetrafluoroethylene, which are conventionally used, can be used. The thickness of the insulating coating is appropriately set according to the outer diameter of the conductor assembly.
When providing a shield layer, various materials having a conventionally known shielding effect can be used.

上記のような構成によれば、ステンレス鋼からなる素線の伸び率が銅又は銅合金からなる素線の伸び率より小さくなるように設定されているので、大きな引張力が加わり、万一素線断線が発生しても、ステンレス素線が銅又は銅合金素線より先に切れるため、発熱等の事態にはいたらない。また、全体として引張強度が十分確保でき、しかも細線化、軽量化が可能となる。   According to the above configuration, since the elongation rate of the strand made of stainless steel is set to be smaller than the elongation rate of the strand made of copper or a copper alloy, a large tensile force is applied. Even if the wire breakage occurs, the stainless steel strand is cut before the copper or copper alloy strand, so that the situation such as heat generation does not occur. In addition, sufficient tensile strength can be ensured as a whole, and further thinning and weight reduction are possible.

第1の自動車用電線は、図示の構成例のみに限定されず、種々の変形、変更が可能である。
例えば、上記では、1本の中心素線の周りを6本の周辺素線で包囲した7本撚りタイプのものとしたが、さらにその周りを12本の周辺素線で包囲した19本撚りタイプのものとしてもよい。
また、上記では、撚線構造としたが、撚線としなくてもよい。
また、上記では、中心素線の素線径を周辺素線の素線径と同じにしたが、所要の引張強度が得られるならば、中心素線の素線径を周辺素線の素線径より小さく、例えば、断面積とした場合70〜95%程度となるようにしてもよい。この場合、電線のより細線化、軽量化が可能となる利点がある。
The first automotive electric wire is not limited to the illustrated configuration example, and various modifications and changes can be made.
For example, in the above description, a single strand is surrounded by 6 peripheral strands, but the 7 strand type is surrounded by 12 peripheral strands. It is good also as a thing.
Moreover, although it was set as the twisted-wire structure in the above, it does not need to be set as a twisted wire.
In the above, the strand diameter of the central strand is the same as the strand diameter of the peripheral strand, but if the required tensile strength is obtained, the strand diameter of the central strand is set to the strand of the peripheral strand. For example, when the cross-sectional area is smaller than the diameter, it may be about 70 to 95%. In this case, there is an advantage that the wire can be made thinner and lighter.

ここで、第1の自動車用電線の作製例を述べる。ステンレス鋼素線の素線径:0.18mm、ステンレス鋼素線の伸び率10%、純銅素線の素線径:0.18mm、純銅素線の伸び率15%、導体の集合体の外径:0.54mmφ、引張強度:120N。この第1の自動車用電線によれば、破断試験を行ったところ、ステンレス鋼素線が純銅素線より先に切れることが確認された。また、細線化、軽量化が図れ、高い引張強度が得られることが確認された。   Here, a production example of the first automobile electric wire will be described. Stainless steel element wire diameter: 0.18 mm, stainless steel element wire elongation: 10%, pure copper element wire diameter: 0.18 mm, pure copper element wire elongation: 15%, outside conductor assembly Diameter: 0.54 mmφ, tensile strength: 120 N. According to the first electric wire for automobiles, when a break test was performed, it was confirmed that the stainless steel wire was cut before the pure copper wire. Moreover, it was confirmed that thinning and weight reduction can be achieved and high tensile strength can be obtained.

次に、本発明による第2の自動車用電線(請求項2に相当)について述べる。第2の自動車用電線は、ステンレス鋼からなる中心素線の周囲に該中心素線を包囲するように銅又は銅合金からなる周辺素線とステンレス鋼からなる周辺素線とを交互に複数本配置してなり、ステンレス鋼からなる素線の伸び率が銅又は銅合金からなる素線の伸び率より小さいことを特徴とする。   Next, a second automobile electric wire (corresponding to claim 2) according to the present invention will be described. The second automotive electric wire includes a plurality of alternating peripheral wires made of copper or copper alloy and peripheral wires made of stainless steel so as to surround the central wire made of stainless steel. It is arranged, and the elongation rate of the strand made of stainless steel is smaller than the elongation rate of the strand made of copper or a copper alloy.

図3に、第2の自動車用電線の一構成例における導体の状態を断面図で示す。図中21は導体の集合体で、ステンレス鋼からなる中心素線22の周囲に、銅又は銅合金からなる周辺素線23とステンレス鋼からなる周辺素線24が交互に配置され、撚りあわされ撚線構造となっている。また、中心素線22の素線径と周辺素線23、24の素線径は等しくなっている。導体の集合体の周りに直接又はシールド層を介して絶縁被覆を設けて、自動車用電線とする。本発明では、前記したように、ステンレス鋼からなる素線の伸び率が銅又は銅合金からなる素線の伸び率より小さく設定される。ステンレス鋼素線の伸び率は銅又は銅合金素線の伸び率より0〜50%小さいことが好ましい。   In FIG. 3, the state of the conductor in the structural example of the 2nd electric wire for motor vehicles is shown with sectional drawing. In the figure, 21 is an assembly of conductors, and a peripheral strand 23 made of copper or a copper alloy and a peripheral strand 24 made of stainless steel are alternately arranged and twisted around a central strand 22 made of stainless steel. It has a stranded wire structure. The strand diameter of the central strand 22 and the strand diameters of the peripheral strands 23 and 24 are equal. An insulating coating is provided directly around the conductor assembly or through a shield layer to obtain an automobile electric wire. In the present invention, as described above, the elongation rate of the strand made of stainless steel is set smaller than the elongation rate of the strand made of copper or a copper alloy. The elongation of the stainless steel wire is preferably 0 to 50% smaller than the elongation of the copper or copper alloy wire.

本構成例の中心素線22に使用されるステンレス鋼は、上記の条件を満足していることが必要であるが、ステンレス鋼の伸び率の調整方法としては、第1の自動車用電線に関して述べた方法を用いることができる。
中心素線12の素線径は、用途に応じて適宜設定されるが、通常、0.1〜0.2mm程度とすることが好ましい。
中心素線22、周辺素線24の素線径は、用途に応じて適宜設定されるが、通常、0.1〜0.2mm程度である。
The stainless steel used for the central strand 22 of this configuration example needs to satisfy the above conditions, but the method for adjusting the elongation of the stainless steel is described with respect to the first automobile wire. Can be used.
Although the strand diameter of the center strand 12 is suitably set according to a use, it is usually preferable to set it as about 0.1-0.2 mm.
The strand diameters of the central strand 22 and the peripheral strand 24 are appropriately set according to the use, but are usually about 0.1 to 0.2 mm.

また、周辺素線23に使用される銅又は銅合金も、第1の自動車用電線の場合と同様、通常電線に使用される各種のタイプのものが使用できるが、導電性、引張強度、伸び等の観点から純銅、Cu−Ag合金、Cu−Ni−Si合金等の使用が好ましい。周辺素線23の素線径は、用途に応じて適宜設定されるが、通常、0.1〜0.2mm程度である。   Also, the copper or copper alloy used for the peripheral wire 23 can be of various types used for ordinary electric wires, as in the case of the first automobile electric wire, but it has conductivity, tensile strength, elongation. From the viewpoint of the above, it is preferable to use pure copper, Cu—Ag alloy, Cu—Ni—Si alloy or the like. Although the strand diameter of the peripheral strand 23 is suitably set according to a use, it is about 0.1-0.2 mm normally.

絶縁被覆も、第1の自動車用電線の場合と同様、従来使用されているポリ塩化ビニル(PVC)、ポリエチレン(発泡系を含む)、ハロゲンフリー材、テトラフロロエチレン等の各種樹脂材料を用いることができる。絶縁被覆の厚さは導体の集合体の外径に応じて適宜設定される。
シールド層を設ける場合には、従来公知のシールド効果を有する各種材料が使用できる。
As in the case of the first automobile electric wire, the insulation coating should be made of various resin materials such as polyvinyl chloride (PVC), polyethylene (including foam), halogen-free materials, and tetrafluoroethylene, which have been used in the past. Can do. The thickness of the insulating coating is appropriately set according to the outer diameter of the conductor assembly.
When providing a shield layer, various materials having a conventionally known shielding effect can be used.

上記のような構成によれば、ステンレス鋼からなる素線の伸び率が銅又は銅合金からなる素線の伸び率より小さくなるように設定されているので、第1の自動車用電線の場合と同様、大きな引張力が加わり、万一素線断線が発生しても、ステンレス素線が銅又は銅合金素線より先に切れるため、発熱等の事態にはいたらない。また、全体として引張強度が十分確保でき、しかもより細線化、軽量化が可能となる。   According to the configuration as described above, since the elongation rate of the strand made of stainless steel is set to be smaller than the elongation rate of the strand made of copper or a copper alloy, Similarly, even if a large tensile force is applied and a strand break occurs, the stainless strand breaks before the copper or copper alloy strand, so that a situation such as heat generation does not occur. In addition, sufficient tensile strength can be secured as a whole, and further thinning and weight reduction can be achieved.

第2の自動車用電線も、図示の構成例のみに限定されず、種々の変形、変更が可能である。
例えば、上記では、1本の中心素線の周りを6本の周辺素線で包囲した7本撚りタイプのものとしたが、さらにその周りを12本の周辺素線で包囲した19本撚りタイプのものとしてもよい。
また、上記では、撚線構造としたが、撚線としなくてもよい。
また、上記では、中心素線の素線径を周辺素線の素線径と同じにしたが、所要の引張強度が得られるならば、中心素線の素線径を周辺素線の素線径より小さく、例えば、断面積とした場合70〜95%程度となるようにしてもよい。この場合、電線のより細線化が可能となる利点がある。
The second automobile electric wire is not limited to the illustrated configuration example, and various modifications and changes can be made.
For example, in the above description, a single strand is surrounded by 6 peripheral strands, but the 7 strand type is surrounded by 12 peripheral strands. It is good also as a thing.
Moreover, although it was set as the twisted-wire structure in the above, it does not need to be set as a twisted wire.
In the above, the strand diameter of the central strand is the same as the strand diameter of the peripheral strand, but if the required tensile strength is obtained, the strand diameter of the central strand is set to the strand of the peripheral strand. For example, when the cross-sectional area is smaller than the diameter, it may be about 70 to 95%. In this case, there is an advantage that the wire can be made thinner.

ここで、第2の自動車用電線の作製例を述べる。ステンレス鋼素線の素線径:0.18mm、ステンレス鋼素線の伸び率10%、純銅素線の素線径:0.18mm、純銅素線の伸び率15%、導体の集合体の外径:0.54mmφ、引張強度:120N。この第2の自動車用電線によれば、破断試験を行ったところ、ステンレス鋼素線が純銅素線より先に切れることが確認された。また、細線化、軽量化が図れ、より高い引張強度が得られることが確認された。   Here, a production example of the second automobile electric wire will be described. Stainless steel element wire diameter: 0.18 mm, stainless steel element wire elongation: 10%, pure copper element wire diameter: 0.18 mm, pure copper element wire elongation: 15%, outside conductor assembly Diameter: 0.54 mmφ, tensile strength: 120 N. According to the second automotive electric wire, when a break test was performed, it was confirmed that the stainless steel strand was cut before the pure copper strand. In addition, it was confirmed that thinning and lightening can be achieved and higher tensile strength can be obtained.
