Description

本発明は、撚線導体に関するものである。   The present invention relates to a stranded conductor.

従来、電線等に使用される撚線導体を構成する各々の素線は、一般的に、全て断面円形の丸線で、かつ、同一径である。この素線として銅線が主として用いられ、その銅線に、錫、ニッケル、銀、或いはアルミ、各種合金をメッキしたものが使用されている。   Conventionally, each of the strands constituting the stranded conductor used for the electric wire or the like is generally a round wire having a circular cross section and the same diameter. A copper wire is mainly used as the wire, and the copper wire plated with tin, nickel, silver, aluminum, or various alloys is used.

37本の素線で構成される撚線導体は、一般的に、図3に示すように、全て同じ素線102を用いて構成されているとともに、撚線導体101における中心の1本の素線102を核として、その周囲を6本の素線102が覆い囲んで第1内層103を形成し、更に、その外周を12本の素線102が覆い囲んで第2内層104を形成し、その周囲を18本の素線102が覆い囲んで最外層105を形成し、それを同一方向に撚ることで形成されている。この撚線導体101を従来技術1とする。   Generally, as shown in FIG. 3, a stranded conductor composed of 37 strands is constructed using all the same strands 102, and one strand at the center of the stranded conductor 101. Six wires 102 surround the wire 102 as a core to form a first inner layer 103, and further, 12 wires 102 surround an outer periphery thereof to form a second inner layer 104, Eighteen strands of wire 102 surround the periphery to form an outermost layer 105, which is formed by twisting in the same direction. This stranded wire conductor 101 is referred to as prior art 1.

素線102が全て、断面円形で、かつ、同一径であることから、素線102を、標準心線配列で配列して撚線導体101を形成すると、その外周形状は、図3に示すように、六角形状に近似した形状となり、丸形状に近似した形状とはならない。   Since all the strands 102 are circular in cross section and have the same diameter, when the strands 102 are arranged in a standard conductor arrangement to form the stranded conductor 101, the outer peripheral shape is as shown in FIG. The shape approximates to a hexagonal shape and does not approximate to a circular shape.

一般的に、撚線導体101は、外周部に絶縁材を被覆した後に、電線等(被覆線)として使用される。被覆線の断面形状は、略真円形状であることが望まれている。一方、絶縁材は、耐圧特性の点から撚線導体の外周部に略均一に被覆されることが望ましい。また、資源の有効利用、被覆線の軽量化の観点から、撚線導体の断面形状は真円であることが望まれている。   In general, the stranded wire conductor 101 is used as a wire or the like (coated wire) after the outer peripheral portion is coated with an insulating material. The cross-sectional shape of the coated wire is desired to be substantially a perfect circle. On the other hand, it is desirable that the insulating material be substantially uniformly coated on the outer peripheral portion of the stranded conductor from the viewpoint of pressure resistance characteristics. From the viewpoint of effective use of resources and weight reduction of the coated wire, it is desirable that the cross-sectional shape of the stranded conductor is a perfect circle.

また、撚線導体の断面形状を真円状とすることで、柔軟で可撓性に優れたものとすることができる。   In addition, by making the cross-sectional shape of the stranded wire conductor a perfect circle, it is possible to be flexible and excellent in flexibility.

このように、撚線導体を、圧縮することなく若しくは低い圧縮率で、断面形状を真円状となるように構成されたもののうち、例えば、4層以上で構成された撚線導体として、図4,図5に示すように、少なくとも最外層202,302及び、その最外層202,302に接するように内側に設けられた最外内層203,303は、線径の異なる複数種類の素線204〜206,304〜308を用いて構成された撚線導体201,301が知られている(例えば、特許文献1,2参照)。この撚線導体2を従来技術2とする。   As described above, for example, as a stranded wire conductor composed of four or more layers among those configured to have a circular cross-sectional shape without compression or at a low compression ratio, the stranded wire conductor is shown in FIG. 4, as shown in FIG. 5, at least the outermost layers 202, 302 and the outermost inner layers 203, 303 provided on the inner side so as to be in contact with the outermost layers 202, 302 The stranded-wire conductor 201,301 comprised using -206,304-308 is known (for example, refer patent document 1, 2). This stranded wire conductor 2 is referred to as prior art 2.

上記従来技術2の撚線導体201,301は、最外内層203,303を、複数種類の素線204〜206,304〜308で構成したことにより、素線204〜206,304〜308を所定の位置に配列することが難しく、安定して撚線導体201,301を製造することは困難であるという問題がある。   In the stranded wire conductors 201 and 301 of the prior art 2 described above, the outermost inner layers 203 and 303 are constituted of a plurality of types of strands 204 to 206, 304 to 308, whereby the strands 204 to 206, 304 to 308 are specified. There is a problem that it is difficult to arrange in the position of (2), and it is difficult to manufacture the stranded conductors 201 and 301 stably.

そこで、本発明は、上記従来技術2の撚線導体201,301より製造が容易で、かつ、撚線導体の断面形状を真円状に近い形状とした撚線導体を提供することを目的とするものである。   Therefore, it is an object of the present invention to provide a stranded conductor which is easier to manufacture than the stranded conductors 201 and 301 of the prior art 2 and in which the cross sectional shape of the stranded conductor is close to a perfect circle. It is

In addition, in order to avoid the complication of a figure, the oblique line which shows the cross section of each strand was abbreviate | omitted.

実施例1に示す撚線導体1は、図1に示すように配列された総数37心の素線を、軸方向に撚ることにより成形されたものである。この素線は、細径線(素線)2と、太径線(素線)3と、内層線(素線)4の3種類により構成されている。   The stranded wire conductor 1 shown in the first embodiment is formed by axially twisting a total of 37 core wires arranged as shown in FIG. This wire is composed of three types of a thin wire (wire) 2, a thick wire (wire) 3 and an inner layer wire (wire) 4.

また、撚線導体1は、中心に位置する1本の内層線4により構成された中心線11と、この中心線11の外周を覆い囲むように配置された6本の内層線4により構成された第1内層12と、この第1内層12の外周を覆い囲むように配置された12本の内層線4により構成された最外内層13と、この最外内層13の外周を覆い囲むように配置された12本の太径線3と6本の細径線2からなる総計18本により形成された最外層14で構成されている。また、中心線11と第1内層12と最外内層13により、内層16が構成されている。   Further, the stranded conductor 1 is constituted by a center line 11 constituted by one inner layer line 4 located at the center, and six inner layer lines 4 arranged so as to surround and surround the outer periphery of the center line 11. The outermost inner layer 13 formed of the first inner layer 12 and the twelve inner layer lines 4 arranged to surround the outer periphery of the first inner layer 12 and the outer periphery of the outermost inner layer 13 The outermost layer 14 is formed of a total of 18 pieces of 12 large-diameter lines 3 and 6 small-diameter lines 2 arranged. Further, an inner layer 16 is constituted by the center line 11, the first inner layer 12 and the outermost inner layer 13.

なお、細径線2と、太径線3と、内層線4は、夫々直径の異なる断面円形(丸形)の線材を基にして形成されたものである。これらの線材としては、従来と同様に、銅線やこの銅線に、錫、ニッケル、銀をメッキしたもの、或いはアルミ線、各種合金線等が使用できる。   The small diameter wire 2, the large diameter wire 3, and the inner layer wire 4 are formed based on wire members of circular cross section (round shape) different in diameter. As these wires, a copper wire or a copper wire plated with tin, nickel, silver, an aluminum wire, various alloy wires or the like can be used as in the prior art.

細径線2の直径dは、内層線4の直径dより小さく形成され、内層線4の直径dは、太径線3の直径dより小さく形成されている。すなわち、太径線3の直径dは、細径線2の直径dと内層線4の直径dより大きく形成されている。 The diameter d 1 of the thin lines 2 are formed smaller than the diameter d 2 of the inner layer line 4, the diameter d 2 of the inner layer line 4 is smaller than the diameter d 3 of the thick diameter line 3. That is, the diameter d 3 of the thick diameter line 3 is larger than the diameter d 2 of the thin lines 2 having a diameter d 1 and the inner line 4.

内層16を構成する中心線11、第1内層12、最外内層13は、全て同じ内層線4で構成され、内層16は、総数19本の内層線4を、標準心線配列で配列して構成されており、内層16の外形状は、図1に示すように、略六角形状に形成されている。   The center line 11, the first inner layer 12, and the outermost inner layer 13 constituting the inner layer 16 are all constituted by the same inner layer line 4, and the inner layer 16 arranges a total of 19 inner layer lines 4 in a standard core line arrangement. As shown in FIG. 1, the outer shape of the inner layer 16 is formed in a substantially hexagonal shape.

最外層14を形成する各細径線2は、図1に示すように、最外内層13を構成する内層線4のうち、中心線11の中心Aから最も遠い位置に位置し、最外内層13の頂部13Aを構成する内層線4Aの外側で、かつ、中心線11の中心と、頂部13Aを構成する内層線4Aを結んだ線上に略位置するように配置されている。   As shown in FIG. 1, each small diameter line 2 forming the outermost layer 14 is located at a position farthest from the center A of the center line 11 among the inner layer lines 4 constituting the outermost inner layer 13 and is the outermost inner layer It is disposed on the outside of the inner layer line 4A constituting the top portion 13A of 13 and on the line connecting the center of the center line 11 and the inner layer line 4A constituting the top portion 13A.

最外層14を構成する太径線3は、図1に示すように、周方向に隣接する細径線2,2間に、周方向に2本配設されている。   As shown in FIG. 1, two large diameter wires 3 constituting the outermost layer 14 are arranged in the circumferential direction between the small diameter wires 2 and 2 adjacent in the circumferential direction.

そして、前記のように形成された撚線導体1の外周に絶縁材を被覆して、電線等に使用できる。   Then, the outer periphery of the stranded wire conductor 1 formed as described above is covered with an insulating material and can be used for a wire or the like.

上記の構成により、撚線導体1の外形形状は、略真円形状に近い形状とすることができる。すなわち、中心線11の中心Aから最外層14を形成する太径線3の最外縁端Bまでの距離L1と、中心線11の中心Aから最外層14を形成する細径線2の最外縁端Cまでの距離L2が略同一となるように形成されている。つまり、最外層14を形成する全ての細径線2、太径線3の最外縁端B、Cは、図1に示すように、中心線11の中心Aから太径線3の最外縁端Bまでの距離L1を半径とする真円線に近い位置に位置するように形成されている。   According to the above-described configuration, the external shape of the stranded wire conductor 1 can be made a shape close to a substantially perfect circular shape. That is, the distance L1 from the center A of the center line 11 to the outermost edge B of the thick line 3 forming the outermost layer 14 and the outermost edge of the thin line 2 forming the outermost layer 14 from the center A of the center line 11 The distance L2 to the end C is formed to be substantially the same. That is, the outermost ends B and C of all the small diameter lines 2 and the large diameter lines 3 forming the outermost layer 14 are the outermost ends of the large diameter line 3 from the center A of the center line 11 as shown in FIG. It is formed to be located at a position close to a perfect circle whose radius is the distance L1 to B.

例えば、
=0.72d ・・・(1)
=1.05d ・・・(2)
の関係式を満たすように設定することにより、撚線導体1を圧縮することなく形成しても、撚線導体1の中心点Aから太径線3の最外縁端Bまでの距離L1と、中心点Aから細径線2の最外縁端Cまでの距離L2が略同一で、かつ、各素線を、隣接する略全ての素線と相互に接触させることができる。
For example,
d 1 = 0.72 d 2 (1)
d 3 = 1.05 d 2 (2)
By setting so as to satisfy the following relational expression, even if the stranded wire conductor 1 is formed without compression, the distance L1 from the center point A of the stranded wire conductor 1 to the outermost end B of the large diameter wire 3; The distance L2 from the center point A to the outermost end C of the thin wire 2 is substantially the same, and each wire can be brought into contact with substantially all adjacent wires.

本実施例1の撚線導体1は、上記の構造を有しているために、次のような作用、効果を奏する。   The stranded conductor 1 according to the first embodiment has the above-described structure, and thus exhibits the following operation and effects.

撚線導体1の外形形状を圧縮することなく、略真円形状とし、かつ、素線2〜4が、隣接する略全ての素線2〜4と接触することができる。   Without compressing the external shape of the stranded wire conductor 1, it can be made into a substantially circular shape, and the strands 2 to 4 can be in contact with substantially all the adjacent strands 2 to 4.

撚線導体1の外形が略真円形状で、絶縁材の被覆を外周全体にわたって、厚みを薄く、かつ、略均一化することができ、絶縁材の減量を図り、コストを低減することができる。   The outer shape of the stranded wire conductor 1 is substantially circular, and the coating of the insulating material can be made thin and substantially uniform over the entire outer periphery, and the amount of the insulating material can be reduced and the cost can be reduced. .

内層16を構成する中心線11、第1内層12、最外内層13を、全て同じ内層線4で構成したことにより、撚線導体1を構成する素線2,3,4の種類を、従来技術2の撚線導体201,301と比較して少なくでき、各素線2,3,4の配設が容易であり、撚線導体1の製造が容易であるとともに、品質を安定化することができる。   Since the center line 11, the first inner layer 12, and the outermost inner layer 13 constituting the inner layer 16 are all constituted by the same inner layer line 4, the types of the strands 2, 3 and 4 constituting the stranded wire conductor 1 It can be reduced compared to the stranded wire conductors 201 and 301 of technology 2, and the arrangement of the individual strands 2, 3 and 4 is easy, the manufacture of the stranded wire conductor 1 is easy, and the quality is stabilized. Can.

また、内層16を全て同じ内層線4で構成したことにより、撚線導体1の製造を行っている途中に、最外内層13と最外層14との位置関係が周方向にずれたとしても、撚線導体1の製造に与える影響は少なく、上記従来技術2の撚線導体201,301と比較して、容易、かつ、安定して、撚線導体1を製造することができる。   Moreover, even if the positional relationship between the outermost inner layer 13 and the outermost layer 14 deviates in the circumferential direction during manufacturing of the stranded wire conductor 1 by forming the inner layer 16 entirely with the same inner layer wire 4, The influence on the production of the stranded conductor 1 is small, and the stranded conductor 1 can be produced easily and stably as compared with the stranded conductors 201 and 301 of the prior art 2 described above.

なお、前記実施例1の撚線導体1を構成する素線は、細径線2の直径dは、内層線4の直径dより小さく形成され、内層線4の直径dは、太径線3の直径dより小さく形成されていれば、任意の径を有する素線以外にも任意の素線を用いて撚線導体1を構成することができる。また、その最外層14の外周部から圧縮ダイス等により圧縮して、撚線導体1を形成するようにしてもよい。 Incidentally, the wire constituting the stranded conductor 1 of the first embodiment, the diameter d 1 of the thin lines 2 are formed smaller than the diameter d 2 of the inner layer line 4, the diameter d 2 of the inner layer line 4 is thick if it is smaller than the diameter d 3 of the meridian 3, it is possible to constitute a stranded conductor 1 using any wire other than the wire having any diameter. Alternatively, the stranded wire conductor 1 may be formed by compressing the outer peripheral portion of the outermost layer 14 with a compression die or the like.

この圧縮により、最外層14を形成する素線2,3の外周部は、圧縮変形され、撚線導体の外形形状をより真円形状に近づけることができる。圧縮ダイス等による圧縮は、撚線導体1を製造する際に行っても良いし、撚線導体1を製造した後に行っても良い。なお、圧縮率に関しては、任意に設定する。   By this compression, the outer peripheries of the strands 2, 3 forming the outermost layer 14 are compressed and deformed, and the outer shape of the stranded conductor can be made closer to a perfect circle. The compression by a compression die or the like may be performed when manufacturing the stranded wire conductor 1 or may be performed after manufacturing the stranded wire conductor 1. The compression rate is arbitrarily set.

Further, an inner layer 36 is configured by the center line 31, the first inner layer 32, the second inner layer 33, and the outermost inner layer 34.

なお、細径線22と、第1太径線23と、第2太径線24と、内層線25は、夫々直径の異なる断面円形(丸形)の線材を基にして形成されたもので、実施例1と同様の線材を用いることができる。   The small diameter wire 22, the first large diameter wire 23, the second large diameter wire 24, and the inner layer wire 25 are formed based on wire members of circular cross section (round shape) different in diameter. The same wire as in Example 1 can be used.

細径線22の直径d11は、内層線25の直径d12より小さく形成され、第1太径線23の直径d13と、第2太径線24の直径d14は、細径線22の直径d11より大きく形成されている。また、第1太径線23の直径d13は、内層線25の直径d12より小さく形成され、第2太径線24の直径d14は、内層線25の直径d12より大きく形成されている。第1太径線23と第2太径線24は、その直径d13,d14が、細径線22の直径d11より大きく形成された太径線である。 The diameter d 11 of the small-diameter wire 22 is formed smaller than the diameter d 12 of the inner layer wire 25, the diameter d 13 of the first thick diameter line 23, the diameter d 14 of the second thick diameter line 24, thin lines 22 It is formed larger than the diameter d 11.

The first large diameter line 23 and the second large diameter line 24 are large diameter lines whose diameters d 13 and d 14 are formed larger than the diameter d 11 of the small diameter line 22.

内層36を構成する中心線31、第1内層32、第2内層33、最外内層34は、全て同じ内層線25で構成され、内層36は、総数37本の内層線25を、標準心線配列で配列して構成されており、内層36の外形状は、図2に示すように、略六角形状に形成されている。   The center line 31, the first inner layer 32, the second inner layer 33, and the outermost inner layer 34 constituting the inner layer 36 are all constituted by the same inner layer line 25, and the inner layer 36 has a total of 37 inner layer lines 25 The outer layer of the inner layer 36 is formed in a substantially hexagonal shape as shown in FIG. 2.

最外層35を形成する各細径線22は、図2に示すように、最外内層34を構成する内層線25のうち、中心線31の中心Dから最も遠い位置に位置し、最外内層34の頂部34Aを構成する内層線25Aの外側で、かつ、中心線31の中心と、頂部33Aを構成する内層線25Aを結んだ線上に略位置するように配置されている。   Each of the small diameter lines 22 forming the outermost layer 35 is located farthest from the center D of the center line 31 among the inner layer lines 25 constituting the outermost inner layer 34, as shown in FIG. It is disposed on the outside of the inner layer line 25A constituting the top portion 34A of 34 and on a line connecting the center of the center line 31 and the inner layer line 25A constituting the top portion 33A.

最外層35を構成する第1太径線23は、図2に示すように、周方向に隣接する細径線22,22間に、周方向に離間して2本配設されている。   As shown in FIG. 2, two first large diameter wires 23 constituting the outermost layer 35 are provided circumferentially apart from each other between the small diameter wires 22 and 22 adjacent in the circumferential direction.

最外層35を構成する第2太径線24は、図2に示すように、周方向に隣接する第1太径線23,23間に1本配設されている。   As shown in FIG. 2, one second thick wire 24 constituting the outermost layer 35 is disposed between the first thick wires 23 and 23 adjacent in the circumferential direction.

そして、前記のように形成された撚線導体21の外周に絶縁材を被覆して、電線等に使用できる。   Then, the outer periphery of the stranded wire conductor 21 formed as described above is covered with an insulating material and can be used for a wire or the like.

上記の構成により、撚線導体21の外形形状は、略真円形状に近い形状とすることができる。すなわち、中心線31の中心Dから最外層35を形成する第2太径線24の最外縁端Eまでの距離L3と、中心線31の中心Dから最外層35を形成する細径線22の最外縁端Fまでの距離L4が略同一となるように形成されている。つまり、最外層35を形成する全ての細径線22、第2太径線24の最外縁端E、Fは、図2に示すように、中心線31の中心Dから第2太径線24の最外縁端Eまでの距離L3を半径とする真円線に近い位置に位置するように形成されている。   According to the above configuration, the external shape of the stranded wire conductor 21 can be made to be a shape close to a substantially perfect circular shape. That is, the distance L3 from the center D of the center line 31 to the outermost end E of the second thick line 24 forming the outermost layer 35, and the thin line 22 forming the outermost layer 35 from the center D of the center line 31 The distance L4 to the outermost edge F is formed to be substantially the same. That is, the outermost edges E and F of all the small diameter lines 22 forming the outermost layer 35 and the second large diameter line 24 are the second large diameter line 24 from the center D of the center line 31 as shown in FIG. It is formed so as to be located near a perfect circle whose radius is the distance L3 to the outermost edge E of the.

例えば、
11=0.68d12 ・・・(3)
13=0.99d12 ・・・(4)
14=1.17d12 ・・・(5)
の関係式を満たすように設定することにより、撚線導体21を圧縮することなく形成しても、撚線導体21の中心点Dから第2太径線24の最外縁端Eまでの距離L3と、中心点Dから細径線22の最外縁端Fまでの距離L4が略同一で、かつ、各素線が、隣接する略全ての素線と相互に接触させることができる。
For example,
d 11 = 0.68 d 12 (3)
d 13 = 0.99 d 12 (4)
d 14 = 1.17 d 12 (5)
The distance L3 from the center point D of the stranded wire conductor 21 to the outermost end E of the second large diameter wire 24 even if the stranded wire conductor 21 is formed without compression by setting so as to satisfy the relational expression of Also, the distance L4 from the center point D to the outermost edge F of the thin wire 22 can be substantially the same, and each wire can be in contact with substantially all adjacent wires.

なお、前記実施例2の撚線導体21を構成する素線は、細径線22の直径d11は、内層線25の直径d12より小さく形成され、第1太径線23の直径d13と、第2太径線24の直径d14は、細径線22の直径d11より大きく形成されていれば、任意の径を有する素線以外にも任意の素線を用いて撚線導体21を構成することができる。また、その最外層35の外周部から圧縮ダイス等により圧縮して、撚線導体21を形成するようにしてもよい。 Incidentally, the wire constituting the stranded conductor 21 of the second embodiment, the diameter d 11 of the small-diameter wire 22 is formed smaller than the diameter d 12 of the inner layer wire 25, the diameter d 13 of the first thick diameter line 23 If the diameter d 14 of the second large diameter wire 24 is larger than the diameter d 11 of the small diameter wire 22, any strand other than the strand having any diameter may be used as a stranded conductor 21 can be configured. Alternatively, the stranded wire conductor 21 may be formed by compressing the outer peripheral portion of the outermost layer 35 with a compression die or the like.

この圧縮により、最外層35を形成する素線22,23,24の外周部は、圧縮変形され、撚線導体の外形形状をより真円形状に近づけることができる。圧縮ダイス等による圧縮は、撚線導体21を製造する際に行っても良いし、撚線導体21を製造した後に行っても良い。なお、圧縮率に関しては、任意に設定する。   By this compression, the outer peripheral portions of the strands 22, 23, 24 forming the outermost layer 35 are compressed and deformed, and the outer shape of the stranded conductor can be made closer to a true circular shape. The compression by a compression die or the like may be performed when manufacturing the stranded wire conductor 21 or may be performed after manufacturing the stranded wire conductor 21. The compression rate is arbitrarily set.

本実施例2においても、上記実施例1と同様の作用、効果を奏する。   In the second embodiment, the same operation and effect as the first embodiment can be obtained.
