Description

高周波電流用の給電線  High frequency current feeder
技術分野  Technical field
[0001] 本発明は、高周波電流を流すための給電線に関するものである。  [0001] The present invention relates to a feeder line for flowing a high-frequency current.
背景技術  Background art
[0002] 日本特許公開平 5— 190026号公報は、複数のリング導体が絶縁層を介して同心 円状に配置された給電線を開示している。一般に、高周波電流が流れる給電線にお いては、電流の周波数が高くなると表皮効果が生じ、交流電流が導体の表面近くの み流れる傾向があり、その結果導線抵抗が増大し、損失が著しく増大してしまう。一 般に表皮効果の程度を示す表皮深さ dは、以下で表される。  Japanese Patent Publication No. 5-190026 discloses a feeder line in which a plurality of ring conductors are arranged concentrically with an insulating layer interposed therebetween. Generally, in a feeder line through which high-frequency current flows, the skin effect occurs when the frequency of the current increases, and alternating current tends to flow only near the surface of the conductor, resulting in increased conductor resistance and a significant increase in loss. Resulting in. In general, the skin depth d, which indicates the degree of the skin effect, is expressed as follows.
表皮深さ： d= (2Z o σ μ Ϋ/2 Skin depth: d = (2Z o σ μ Ϋ / 2
ω：周波数、 σ：材料の導電率、 μ：材料の透磁率  ω: frequency, σ: material conductivity, μ: material permeability
即ち、給電線の厚さを周波数にて決定される表皮深さ d以下とすれば、表皮効果によ る電流損失が低減できる。このため、上記の従来の給電線では、各リング導体の厚さ を 1ミクロンとすることで、電流損失を抑制している。  In other words, if the thickness of the feeder line is not more than the skin depth d determined by the frequency, current loss due to the skin effect can be reduced. For this reason, in the above-mentioned conventional feeder, current loss is suppressed by setting the thickness of each ring conductor to 1 micron.
[0003] し力しながら、このような構造の給電線は、リング導体の表面に絶縁層を被覆するェ 程を何度も繰り返す必要があって製造時間が長くなり、また、リング導体の位置決め が難しいといる問題がある。  [0003] However, it is necessary to repeat the process of covering the surface of the ring conductor with the insulating layer over and over again, which increases the manufacturing time and the positioning of the ring conductor. There is a problem that is difficult.
発明の開示  Disclosure of the invention
[0004] 本発明は、上述の点に鑑みて為されたもので、その目的とするところは、高周波電 流の損失の低減を図ることができるとともに、製造性も向上させた高周波電流用の給 電線を提供することにある。  [0004] The present invention has been made in view of the above points, and its object is to reduce the loss of high-frequency current and improve the manufacturability. The purpose is to provide power lines.
[0005] 本発明に係る給電線は、導体とこれを被覆する絶縁シースで構成される。導体は、 その長さ方向に直交する断面にぉ 、て、この断面を横切る少なくとも一つの方向に ぉ 、て、導体の一部が他部と所定の間隔で隔てられた単一の構造体として形成され る。絶縁シースは合成樹脂の成型体であり、上記絶縁シース内に上記の導体が一体 に成形される。このため、導体を流れる電流によって生じる磁束の方向に垂直な方向 に沿って、導体が分断されることで、表皮効果による電流の損出を低減することがで きることに加えて、榭脂成形体である絶縁シース内に単一の構造体である導体が一 体に成形されることで、製造性が向上できる。 [0005] A feeder line according to the present invention includes a conductor and an insulating sheath covering the conductor. The conductor has a cross-section perpendicular to its length direction, and in at least one direction crossing the cross-section, and a part of the conductor is separated from the other part at a predetermined interval as a single structure. It is formed. The insulating sheath is a synthetic resin molded body, and the conductor is integrally formed in the insulating sheath. For this reason, the direction perpendicular to the direction of the magnetic flux generated by the current flowing through the conductor In addition to being able to reduce current loss due to the skin effect, the conductor as a single structure is formed in the insulating sheath as the resin molded body. Productivity can be improved by molding into a single unit.
[0006] 導体には、上記の断面に表れる閉空間が形成されて、この閉空間によって導体の 一部が他部と隔てられることが好ましい。この場合、閉空間が絶縁樹脂で満たされる ことがなぐこの閉空間を給電線の接続部材が挿入される空間として利用できる。  [0006] It is preferable that a closed space appearing in the cross section is formed in the conductor, and a part of the conductor is separated from the other part by the closed space. In this case, this closed space where the closed space is not filled with the insulating resin can be used as a space into which the connecting member of the feeder line is inserted.
[0007] また、上記の導体が内筒と外筒を備え、上記内筒と上記外筒とが互いの周上の一 所でのみ結合されることが好ましい。導体を内筒と外筒とで構成することで、各筒を薄 くしながらも導体全体の強度が向上できる。また、導体のほぼ全周に亘つて、内筒と 外筒とが半径方向に沿って離間するため、導体を流れる電流によって発生する磁束 の方向と直交する方向において、導体の厚さを薄くすることができて、電流損出を最 小とすることが出来る。  [0007] Further, it is preferable that the conductor includes an inner cylinder and an outer cylinder, and the inner cylinder and the outer cylinder are coupled only at one place on the circumference of each other. By configuring the conductor with an inner cylinder and an outer cylinder, the strength of the entire conductor can be improved while making each cylinder thinner. In addition, since the inner cylinder and the outer cylinder are separated along the radial direction over almost the entire circumference of the conductor, the thickness of the conductor is reduced in the direction orthogonal to the direction of the magnetic flux generated by the current flowing through the conductor. Current loss can be minimized.
[0008] 更に、上記の外筒は、上記の断面において、その輪郭が外側に突出する弧状部と 平坦部とで構成されることが好ましい。この平坦部は、給電線の接続に使用する接続 部材との接触面として使用でき、接続部材との安定した電気接続が可能となる。  [0008] Furthermore, it is preferable that the outer cylinder is configured by an arc-shaped portion and a flat portion whose contour projects outward in the cross section. This flat portion can be used as a contact surface with a connection member used for connecting a power supply line, and stable electrical connection with the connection member is possible.
[0009] また、上記の外筒は、上記の断面において、互いに直径方向に対向する左右一対 の平坦部と、上下一対の外側に突出する弧状部とで構成されることが好ましい。この 場合、 2つの平坦部を給電線の接続部材との接触面とすることができ、 2つの平坦部 を挟み付ける形状の接続部材を使用して、給電線同士の接続を確実に行うことが出 来る。  [0009] Further, the outer cylinder preferably includes a pair of left and right flat portions opposed to each other in the diametrical direction and a pair of upper and lower arc-shaped portions protruding outward in the cross section. In this case, the two flat portions can be used as a contact surface with the connecting member of the power supply line, and the connecting member having a shape sandwiching the two flat portions can be used to reliably connect the power supply lines. Come out.
[0010] 上記の導体は一枚の金属板を折り曲げて形成されることが好ましい。これにより、導 体の各部分での厚さを薄くできて電流損失を抑制できると共に、所定の断面形状を 容易に作り出すことが出来る。  [0010] The conductor is preferably formed by bending a single metal plate. As a result, the thickness of each part of the conductor can be reduced, current loss can be suppressed, and a predetermined cross-sectional shape can be easily created.
[0011] 更に、上記の導体の断面形状を、その全周において、所定の間隔で半径方向に分 断されることも好ましい。この場合、厚さの薄い導体の一部を半径方向に沿って複数 並べることができ、電流損失を少なくしながらも導体の断面積を大きくして、大きな電 流容量を確保できる。  [0011] Further, it is also preferable that the cross-sectional shape of the conductor is divided in a radial direction at a predetermined interval on the entire circumference. In this case, it is possible to arrange a plurality of thin conductors along the radial direction, and it is possible to secure a large current capacity by increasing the cross-sectional area of the conductor while reducing current loss.

[0013] (第 1の実施形態） [0013] (First embodiment)
本発明の第 1の実施形態に係る高周波電流用の給電線を、図 1と図 2に基づいて 説明する。給電線は、絶縁性の榭脂成形体である絶縁シース 10と、この中に、例え ば、インサートによって一体に成形された導体 20とで構成される。導体 20は、一枚の 金属板を折り曲げて形成される円形の内筒 21と円形の外筒 26を備える。内筒 21と 外筒 26とは同軸上に位置し、互いの周上の一箇所のみで半径方向に走る結合片 2 8によって結合されて、単一構造体の導体 20が得られる。絶縁シース 10は外筒 26の 全周を覆い、内筒 21内部の空間及び内筒 21と外筒 26との間のギャップは、断面に おいて閉空間となり、絶縁樹脂が充填されない空間として残る。導体 20を形成する 金属板は、例えば、厚さが 0.5から 0.8mmの銅板が使用され、外筒 26の外周の一所 で端部同士を溶接により接合して、外筒 26の内部及び内筒 21を絶縁シース 10から 隔離している。  A high-frequency current feeder according to a first embodiment of the present invention will be described with reference to FIGS. The power supply line includes an insulating sheath 10 that is an insulating resin molded body, and a conductor 20 that is integrally formed by an insert, for example. The conductor 20 includes a circular inner cylinder 21 and a circular outer cylinder 26 formed by bending a single metal plate. The inner cylinder 21 and the outer cylinder 26 are located on the same axis, and are coupled by a coupling piece 28 that runs in a radial direction only at one location on the periphery of each other, whereby a conductor 20 having a single structure is obtained. The insulating sheath 10 covers the entire circumference of the outer cylinder 26, and the space inside the inner cylinder 21 and the gap between the inner cylinder 21 and the outer cylinder 26 are closed in the cross section and remain as a space not filled with insulating resin. . The metal plate that forms the conductor 20 is, for example, a copper plate having a thickness of 0.5 to 0.8 mm. The ends of the outer tube 26 are joined together by welding at the outer periphery of the outer tube 26 so that the inside and the inside of the outer tube 26 are joined. The cylinder 21 is isolated from the insulating sheath 10.
[0014] このように、絶縁シース 10内では、内筒 21と外筒 26とが、結合片 28の部位を除い て、半径方向に離間して、この間にギャップを形成する。このため、導体 20のほぼ全 周に亘つて、導体を流れる電流によって発生する磁束の方向（図 2の矢印で示す）と 直交する方向に沿って導体が分断されることになり、導体 20全体の断面積を確保し て所定の電流容量を満足しながらも、表皮効果や近接効果による高周波特有の電 流損失を低減することができる。また、導体 20は単一の構造体であるため、絶縁シー ス 10内での位置決めが容易であり、給電線の製造が容易となる。  As described above, in the insulating sheath 10, the inner cylinder 21 and the outer cylinder 26 are separated in the radial direction except for the portion of the coupling piece 28, and a gap is formed therebetween. For this reason, the conductor is divided along the direction perpendicular to the direction of the magnetic flux generated by the current flowing through the conductor (indicated by the arrow in FIG. 2) over almost the entire circumference of the conductor 20. The current loss peculiar to the high frequency due to the skin effect and the proximity effect can be reduced while ensuring a predetermined cross-sectional area and satisfying a predetermined current capacity. Further, since the conductor 20 is a single structure, positioning within the insulating sheath 10 is easy, and manufacturing of the feeder line is facilitated.
[0015] 図 3及び図 4は、接続具 30を使用した給電線同士の接続構造を示す。接続具 30 は、給電線の端部が挿入されるソケット 34を両側に備えた絶縁性の基台 32と、各ソ ケット内 34に突出するプラグ 36で構成され、各プラグ 36を外筒 26の内周面に圧接さ せることで、給電線の接続が行える。各プラグ 36は一対の断面が弧状の接続片で形 成され、その厚さは上記のギャップ厚よりも十分に小さくされており、内筒 21との間に 十分な距離を残す。このため、給電線の接続を、内筒 21と外筒 26との間の空間を利 用して行われるものの、給電線の接続部においても、電流の損失を少なくできる。好 ましくは、導体 20の厚さが 0.5から 0.8mmで、外筒 26の内径が 5から 10mm、内筒 21の 外径を 4カゝら 6mmとしている。このような接続方式では、給電線の端部の絶縁シース 1 0を剥がす必要がなぐ単に給電線の端部を接続具のソケット 34内に挿入することで 簡単な接続が行える。 3 and 4 show a connection structure between the feeder lines using the connection tool 30. FIG. The connector 30 includes an insulating base 32 having sockets 34 on both sides into which end portions of the power supply lines are inserted, and plugs 36 protruding into the sockets 34. The power supply line can be connected by press-contacting to the inner peripheral surface of the cable. Each plug 36 has a pair of cross-sections formed by arc-shaped connecting pieces, the thickness of which is sufficiently smaller than the gap thickness described above, and between the inner cylinder 21 and each plug 36. Leave enough distance. For this reason, although the connection of the power supply line is performed using the space between the inner cylinder 21 and the outer cylinder 26, current loss can also be reduced at the connection part of the power supply line. Preferably, the thickness of the conductor 20 is 0.5 to 0.8 mm, the inner diameter of the outer cylinder 26 is 5 to 10 mm, and the outer diameter of the inner cylinder 21 is 4 to 6 mm. In such a connection method, a simple connection can be made by simply inserting the end of the feeder into the socket 34 of the connector without having to peel off the insulating sheath 10 at the end of the feeder.
