[本願発明の実施形態の詳細]
以下、図面を参照しながら、本実施形態に係る電線の概略を説明する。図１は、本実施形態に係る電線の例を示している。 [Details of the embodiment of the present invention]
Hereinafter, the outline of the electric wire according to the present embodiment will be described with reference to the drawings. FIG. 1 shows an example of an electric wire according to this embodiment.

本実施形態に係る細径電線（電線の一例）１は、例えば、車両用のハーネスに用いられる。
図１に示すように、細径電線１は、導体１０と、絶縁層２０とを備えている。 A small-diameter electric wire (an example of an electric wire) 1 according to this embodiment is used, for example, in a harness for a vehicle.
As shown in FIG. 1, the small-diameter electric wire 1 includes a conductor 10 and an insulating layer 20.

本実施形態に係る導体１０は、複数本（ここでは７本）の素線１２を撚り合わせてから圧縮した撚線圧縮導体として構成されている。導体１０を構成する素線１２は、銅、軟銅、銀めっき軟銅、ニッケルめっき軟銅、錫めっき軟銅等の、一般に汎用されている導体材料から構成されている。これらの素線１２を撚り合わせた撚線導体を圧縮して撚線の外径が円形に近づくように整形することで、通常の撚線導体よりも細径化を図るとともに、導体１０の真円度が高くなるようにしている。撚線圧縮導体である導体１０の断面積は、０．０７ｍｍ２（直径０．３ｍｍ）以上０．２８ｍｍ２（直径０．６ｍｍ）以下程度であり、例えば０．１３ｍｍ２である。 The conductor 10 according to the present embodiment is configured as a stranded wire compressed conductor in which a plurality (seven in this case) of strands 12 are twisted and then compressed. The strand 12 which comprises the conductor 10 is comprised from the conductor materials generally used widely, such as copper, an annealed copper, silver plating anodized copper, nickel plating anodized copper, tin plating anodized copper. By compressing the stranded wire conductor obtained by twisting these strands 12 and shaping the stranded wire so that the outer diameter of the stranded wire approaches a circular shape, the diameter of the conductor 10 can be made smaller than that of a normal stranded wire conductor. I try to increase the circularity. The cross-sectional area of the conductor 10 which is a stranded wire compression conductor is about 0.07 mm 2 (diameter 0.3 mm) or more and 0.28 mm 2 (diameter 0.6 mm) or less, for example, 0.13 mm 2 .

導体１０の周囲には、絶縁層２０が単層で引落押出により被覆されている。絶縁層２０を構成する樹脂材料としては、架橋フッ素樹脂を用いることが好ましい。絶縁層２０に用いられるフッ素樹脂としては、例えば、ＥＴＦＥ（エチレンとテトラフルオロエチレンの共重合体）を用いることができる。絶縁層２０は、耐摩耗性や耐熱性および耐油性を向上するために、導体１０の周囲に単層で被覆された後に、電離放射線（γ線や電子線など）の照射や過酸化物架橋、シラン架橋などの化学架橋によって架橋処理される。   Around the conductor 10, an insulating layer 20 is covered with a single layer by pulling extrusion. As the resin material constituting the insulating layer 20, it is preferable to use a cross-linked fluororesin. As the fluororesin used for the insulating layer 20, for example, ETFE (copolymer of ethylene and tetrafluoroethylene) can be used. The insulating layer 20 is coated with a single layer around the conductor 10 in order to improve wear resistance, heat resistance and oil resistance, and then irradiated with ionizing radiation (γ rays, electron beams, etc.) or peroxide crosslinked. Crosslinking is performed by chemical crosslinking such as silane crosslinking.

なお、本実施形態においては、導体１０を被覆する単層の絶縁層２０の厚さは０．２ｍｍ以上０．３ｍｍ以下である。そして、このように構成された細径電線１は、その外径が０．７ｍｍ以上１．０ｍｍ以下の範囲内とすることができる。   In the present embodiment, the thickness of the single insulating layer 20 covering the conductor 10 is not less than 0.2 mm and not more than 0.3 mm. And the thin diameter electric wire 1 comprised in this way can be made into the range whose outer diameter is 0.7 mm or more and 1.0 mm or less.

＜評価＞
ここで、本実施形態に係る細径電線の耐摩耗性を評価するため、スクレープ摩耗試験（ＪＡＳＯ Ｄ ６１８：２０１３，６．７．２）を行った。このスクレープ摩耗試験においては、電線をサンプルホルダーに載置し、直径０．４５ｍｍの針を荷重７Ｎで電線に押し当てて６０サイクル／ｍｉｎで往復させ、電線の絶縁層が摩耗して針が電線の導体に接するまでの往復回数を測定した。 <Evaluation>
Here, a scrape wear test (JASO D 618: 2013, 6.7.2) was performed in order to evaluate the wear resistance of the thin wire according to the present embodiment. In this scrape wear test, an electric wire is placed on a sample holder, a needle having a diameter of 0.45 mm is pressed against the electric wire with a load of 7 N, and reciprocated at 60 cycles / min. The number of reciprocations until contact with the conductor was measured.

表１に例１および例２の電線の具体的な構成およびスクレープ摩耗試験の結果を示す。例１は本実施形態に係る細径電線の一例を示し、例２は比較例に係る電線を示している。例１の絶縁層は、架橋ＥＴＦＥから構成されている。一方、例２の絶縁層は架橋フッ素ゴム（テトラフルオロエチレンとポリプロピレンの共重合体）から構成されている。

Figure 2016189272
Table 1 shows the specific configuration of the electric wires of Example 1 and Example 2 and the results of the scrape wear test. Example 1 shows an example of a thin wire according to this embodiment, and Example 2 shows a wire according to a comparative example. The insulating layer of Example 1 is composed of crosslinked ETFE. On the other hand, the insulating layer of Example 2 is composed of cross-linked fluororubber (a copolymer of tetrafluoroethylene and polypropylene).
Figure 2016189272

上記の表１に示すように、本実施形態に係る例１の細径電線の外径は０．９５ｍｍであり、比較例に係る例２の電線（外径：１．７ｍｍ）よりも外径比で４５％程度も細径化された。この細径化された例１に係る細径電線においては、当該電線の絶縁層が摩耗して針が導体に接するまでの往復回数は１２１サイクルであった。一方、比較例に係る例２の電線においては、当該電線の絶縁層が例１の絶縁層よりも厚いにもかかわらず、針が導体に接するまでの往復回数は２２サイクルであった。すなわち、本実施形態に係る細径電線を用いることで、耐摩耗性が大きく向上することが確認された。   As shown in Table 1 above, the outer diameter of the thin electric wire of Example 1 according to the present embodiment is 0.95 mm, which is larger than that of the electric wire of Example 2 (outer diameter: 1.7 mm) according to the comparative example. The diameter was reduced by about 45%. In the thin electric wire according to the reduced diameter example 1, the number of reciprocations until the needle contacted the conductor after the insulating layer of the electric wire was worn was 121 cycles. On the other hand, in the electric wire of Example 2 according to the comparative example, although the insulating layer of the electric wire was thicker than the insulating layer of Example 1, the number of reciprocations until the needle contacted the conductor was 22 cycles. That is, it has been confirmed that the wear resistance is greatly improved by using the thin wire according to the present embodiment.

以上説明したように、本実施形態にかかる細径電線１においては、撚線圧縮導体から構成された導体１０の周囲に単層の架橋フッ素樹脂層から構成された厚さ０．２ｍｍ以上０．３ｍｍ以下の絶縁層２０が被覆されている。これにより、細径電線１の外径を０．７ｍｍ以上１．０ｍｍ以下と細径化することができる。そのため、細径電線１が例えば車両用ハーネスとして用いられる場合に、狭いスペース内での配線作業（取り回し）を容易にし、省スペース化や軽量化が可能となる。   As described above, in the small-diameter electric wire 1 according to the present embodiment, the thickness of 0.2 mm or more formed of a single layer of a cross-linked fluororesin layer around the conductor 10 formed of a stranded wire compression conductor is 0. An insulating layer 20 of 3 mm or less is covered. Thereby, the outer diameter of the thin wire 1 can be reduced to 0.7 mm or more and 1.0 mm or less. Therefore, when the thin wire 1 is used as, for example, a vehicle harness, wiring work (managing) in a narrow space is facilitated, and space saving and weight reduction are possible.

また、本実施形態の細径電線１は、導体１０が撚線圧縮導体から構成されているため、この導体１０の周囲に薄肉化された絶縁層２０が単層で被覆されていても、撚り合わせた素線１２の外形が撚り波として絶縁層２０の外表面に現れるようなことがなく、良好な外観を確保することができる。そして、細径電線１は、その外表面に撚り波を起因とする凹凸がないため、摩擦係数が小さくなり（スクレープ摩耗試験における絶縁層への針の引っ掛かりが少なくなり）、耐摩耗性に優れている。   Moreover, since the conductor 10 is comprised from the twisted wire compression conductor, even if the thin insulating layer 20 is coat | covered with the single layer in the circumference | surroundings of this conductor 10, the thin wire 1 of this embodiment is twisted. The outer shape of the combined strands 12 does not appear on the outer surface of the insulating layer 20 as a twist wave, and a good appearance can be ensured. And since the thin wire 1 has no irregularities caused by twisted waves on its outer surface, the friction coefficient is small (the needle is not caught on the insulating layer in the scrape wear test), and the wear resistance is excellent. ing.

また、本実施形態においては、絶縁層２０が架橋フッ素樹脂から構成されている。そのため、絶縁層２０が単層で構成され、その厚さが０．２〜０．３ｍｍと薄肉化されていても、耐摩耗性だけではなく、耐熱性および耐油性にも優れた細径電線１を提供することができる。   In the present embodiment, the insulating layer 20 is made of a crosslinked fluororesin. Therefore, even if the insulating layer 20 is composed of a single layer and the thickness thereof is thinned to 0.2 to 0.3 mm, the thin wire is excellent not only in wear resistance but also in heat resistance and oil resistance. 1 can be provided.

以上、本発明を詳細にまた特定の実施態様を参照して説明したが、本発明の精神と範囲を逸脱することなく様々な変更や修正を加えることができることは当業者にとって明らかである。また、上記説明した構成部材の数、位置、形状等は上記実施の形態に限定されず、本発明を実施する上で好適な数、位置、形状等に変更することができる。   While the invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. In addition, the number, position, shape, and the like of the constituent members described above are not limited to the above-described embodiments, and can be changed to a number, position, shape, and the like that are suitable for carrying out the present invention.
