Description

本発明は、端子付き平型電線に関する。 TECHNICAL FIELD The present invention relates to a flat electric wire with a terminal.

工場等の設備あるいは電気自動車やハイブリッド自動車等の車両では、制御盤等の装置間に配線される配線材として、従来、配線部分の形状に合わせて成形されたバスバが用いられてきた（例えば、特許文献１，２参照）。 Conventionally, busbars molded to match the shape of wiring portions have been used as wiring materials for wiring between devices such as control panels in facilities such as factories or vehicles such as electric vehicles and hybrid vehicles (for example, See Patent Documents 1 and 2).

特開２０１９－８７４７１号公報JP 2019-87471 A 特開２０２０－１７７８７８号公報JP 2020-177878 A

近年、カーボンニュートラル社会の実現に向けて、例えば、産業用ロボットが使用される設備では、省エネルギー設備への更新が進んでいる。このような設備の更新に伴って、制御盤等の装置間に配線される配線材についても更新が必要となる。しかし、更新後の設備に応じたバスバを製造するためには、バスバの形状に応じた成形用の金型が必要になる。そのため、更新後の設備に応じた様々な配線形状に応じて、多種多様な金型が必要になる上、同形状のバスバの生産量は少ない傾向にある。このように、バスバは、汎用性が低く少量多品種となりやすいため、装置間の配線材としてバスバを用いる場合、生産コストが高くなってしまうという課題がある。 In recent years, toward the realization of a carbon-neutral society, for example, facilities using industrial robots are being upgraded to energy-saving facilities. Along with the renewal of such facilities, it is also necessary to renew the wiring materials that are wired between devices such as control panels. However, in order to manufacture a busbar suitable for the equipment after renewal, a molding die suitable for the shape of the busbar is required. Therefore, a wide variety of molds are required according to various wiring shapes according to the equipment after renewal, and the production volume of bus bars of the same shape tends to be small. As described above, the bus bar has low versatility and tends to be produced in a small quantity and in a large variety. Therefore, when the bus bar is used as a wiring material between devices, there is a problem that the production cost increases.

そこで、本発明者らは、バスバよりも汎用性が高い装置間の配線材として、導体が編組導体からなる平型電線を用いることを考えた。 Therefore, the present inventors considered using a flat electric wire in which the conductor is a braided conductor as a wiring material between devices, which is more versatile than the bus bar.

しかしながら、平型電線の端部には、装置と平型電線との接続のための端子が設けられるが、この端子の形状によっては平型電線を捩じって配線しなければならない場合があった。また、曲げにくい平型電線を用いると、特に装置間の狭い場所に配線する場合には、平型電線が蛇行して周囲の装置に干渉してしまう場合もあった。 However, although a terminal is provided at the end of the flat electric wire for connection between the device and the flat electric wire, the flat electric wire may have to be twisted for wiring depending on the shape of the terminal. rice field. Moreover, when a flat electric wire that is difficult to bend is used, especially when wiring is performed in a narrow space between devices, the flat electric wire may meander and interfere with surrounding devices.

そこで、本発明は、曲げやすく配線しやすい端子付き平型電線を提供することを目的とする。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a flat electric wire with a terminal that is easy to bend and easy to wire.

本発明は、上記課題を解決することを目的として、複数本の金属素線を編み合わせて構成された帯状の導体、及び前記導体の周囲を被覆している絶縁体を有する平型電線と、前記平型電線の少なくとも一方の端部に設けられ、前記絶縁体の端部から露出された前記導体の端部に固定される固定部、及び被接続部材との固定用の平板状の接続部を一体に有する端子と、を備え、前記平型電線の厚さＨと幅Ｗとの比（Ｗ／Ｈ）が４以上であり、前記端子は、前記接続部の法線方向が前記平型電線の厚さ方向と交差するように設けられている、端子付き平型電線を提供する。 In order to solve the above problems, the present invention provides a flat electric wire having a belt-shaped conductor formed by weaving together a plurality of metal wires, and an insulator covering the circumference of the conductor, A fixing part provided at at least one end of the flat electric wire and fixed to the end of the conductor exposed from the end of the insulator, and a flat connecting part for fixing to a member to be connected and a terminal integrally having the flat wire, wherein the ratio (W/H) of the thickness H and the width W of the flat electric wire is 4 or more, and the terminal has the flat wire in the normal direction of the connection part To provide a flat electric wire with a terminal provided so as to intersect the thickness direction of the electric wire.

本発明によれば、曲げやすく配線しやすい端子付き平型電線を提供できる。 ADVANTAGE OF THE INVENTION According to this invention, the flat electric wire with a terminal which is easy to bend and is easy to wire can be provided.

［実施の形態］
以下、本発明の実施の形態を添付図面にしたがって説明する。 [Embodiment]
BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the accompanying drawings.

図１は、本実施の形態に係る端子付き平型電線１を示す図であり、（ａ）は斜視図、（ｂ）は（ａ）の要部拡大図、（ｃ）は（ａ）のＡ－Ａ線断面図である。 FIG. 1 is a diagram showing a flat electric wire 1 with a terminal according to the present embodiment, (a) is a perspective view, (b) is an enlarged view of a main part of (a), and (c) is a It is a sectional view taken along line AA.

図１（ａ）～（ｃ）に示すように、端子付き平型電線１は、平型電線２と、平型電線２の少なくとも一方の端部に設けられた端子３と、熱収縮チューブ４と、を備えている。 As shown in FIGS. 1(a) to 1(c), a flat electric wire 1 with a terminal includes a flat electric wire 2, a terminal 3 provided at at least one end of the flat electric wire 2, and a heat-shrinkable tube 4. and have.

（平型電線２）
平型電線２は、複数本の金属素線を編み合わせて構成された帯状の導体２１と、導体２１の周囲を被覆している絶縁体２２と、を有している。 (Flat electric wire 2)
The flat electric wire 2 has a belt-shaped conductor 21 formed by weaving together a plurality of metal wires, and an insulator 22 covering the conductor 21 .

導体２１は、環状の編組導体を潰して平坦にすることで形成される。例えば、同軸線を製造する際には、導体の周囲に絶縁体を被覆したコアの周囲に編組導体を設けるが、本実施の形態ではコアを通さない状態で環状の編組導体を形成し、その後プレス等で編組導体を平坦にすることで、導体２１が形成される。平型電線２を曲げやすくするために、導体２１に用いる金属素線としては、なるべく細いものを用いることが望ましい。金属素線の直径としては、例えば、０．１０ｍｍ以上０．２０ｍｍ以下である。ここでは、直径０．１２ｍｍの金属素線を１９４４本編み合わせることで、導体断面積が２２ｍｍ２の導体２１を形成した。 The conductor 21 is formed by flattening an annular braided conductor. For example, when manufacturing a coaxial line, a braided conductor is provided around a core coated with an insulator around the conductor. The conductor 21 is formed by flattening the braided conductor by pressing or the like. In order to make the flat electric wire 2 easy to bend, it is desirable to use as thin a metal wire as possible for the conductor 21 . The diameter of the metal wire is, for example, 0.10 mm or more and 0.20 mm or less. Here, the conductor 21 having a conductor cross-sectional area of 22 mm 2 was formed by braiding 1944 metal strands with a diameter of 0.12 mm.

本実施の形態では、導体２１に用いる金属素線として、すずめっき軟銅線を用いた。ただし、導体２１に用いる金属素線はこれに限らず、例えば、銅合金線、アルミニウム線、あるいはアルミニウム合金線等であってもよい。また、導体２１に用いる金属素線として、抗張力線の周囲に螺旋状に銅箔を巻き付けた銅箔糸を用いることもできる。さらに、アルミニウム又はアルミニウム合金からなる第１金属素線と、銅又は銅合金からなる第２金属素線とを交差するように編み合わせた編組導体により導体２１を構成してもよい。モジュラスの低いアルミニウム又はアルミニウム合金からなる第１金属素線を含む導体２１とすることで、平型電線２を曲げやすくすることができ、かつ平型電線２を曲げたときに曲げた形状のまま形状保持しやすくなるため、装置間の狭い場所に配線するときの配線作業がより容易になる。 In this embodiment, a tin-plated annealed copper wire is used as the metal wire used for the conductor 21 . However, the metal wire used for the conductor 21 is not limited to this, and may be, for example, a copper alloy wire, an aluminum wire, an aluminum alloy wire, or the like. As the metal wire used for the conductor 21, a copper foil yarn obtained by spirally winding a copper foil around a tensile strength wire can also be used. Furthermore, the conductor 21 may be configured by a braided conductor in which a first metal wire made of aluminum or an aluminum alloy and a second metal wire made of copper or a copper alloy are interwoven so as to cross each other. The flat electric wire 2 can be easily bent by using the conductor 21 including the first metal element wire made of aluminum or an aluminum alloy having a low modulus, and the bent shape of the flat electric wire 2 is maintained when the flat electric wire 2 is bent. Since it becomes easier to maintain the shape, wiring work becomes easier when wiring in a narrow space between devices.

なお、ここでは導体２１が編組導体である場合を説明したが、導体２１は、複数本の金属素線を織機等で織り合わせて帯状としたものであってもよい。つまり、本明細書において、「金属素線を編み合わせて構成された」という表現には、金属素線を織り合わせることも含まれる。 Although the case where the conductor 21 is a braided conductor has been described here, the conductor 21 may be formed into a belt shape by interweaving a plurality of metal wires with a loom or the like. In other words, in this specification, the expression "composed of interwoven metal wires" also includes interlacing of metal wires.

絶縁体２２は、導体２１を保護するためのものであり、例えば、ポリ塩化ビニル樹脂を主成分とする樹脂組成物からなる。絶縁体２２の厚さは、１．５ｍｍ以上２．０ｍｍ以下であるとよい。絶縁体２２の厚さを１．５ｍｍ以上とすることで、絶縁体２２の機械的強度を確保でき、絶縁体２２の厚さを２．０ｍｍ以下とすることで、平型電線２を曲げやすくすることができる。本実施の形態では、絶縁体２２の厚さを１．８ｍｍとした。 The insulator 22 is for protecting the conductor 21, and is made of, for example, a resin composition containing polyvinyl chloride resin as a main component. The thickness of the insulator 22 is preferably 1.5 mm or more and 2.0 mm or less. By setting the thickness of the insulator 22 to 1.5 mm or more, the mechanical strength of the insulator 22 can be ensured, and by setting the thickness of the insulator 22 to 2.0 mm or less, the flat electric wire 2 can be easily bent. can do. In this embodiment, the thickness of insulator 22 is set to 1.8 mm.

絶縁体２２は、導体２１の周囲に挿入押出により被覆される。これにより、平型電線２を曲げたときに絶縁体２２内で導体２１が動ける程度に導体２１の表面と絶縁体２２の内面とを密着させることができるため、平型電線２をより曲げやすくなる。 The insulator 22 is wrapped around the conductor 21 by insertion extrusion. As a result, the surface of the conductor 21 and the inner surface of the insulator 22 can be brought into close contact with each other to the extent that the conductor 21 can move within the insulator 22 when the flat electric wire 2 is bent, so that the flat electric wire 2 can be easily bent. Become.

本実施の形態では、平型電線２の厚さＨと幅Ｗとの比（Ｗ／Ｈ）が、４以上とされる。これにより、平型電線２がより扁平な形状となるため、平型電線２を曲げやすくなる。ここでは、平型電線２の厚さＨを６．１ｍｍ、幅Ｗを３０ｍｍとし、これらの比（Ｗ／Ｈ）を約４．９とした。なお、導体２１における厚さ（最大厚さ）Ｈｄと幅（最大幅）Ｗｄとの比（Ｗｄ／Ｈｄ）についても、４倍以上であることが望ましい。 In this embodiment, the ratio (W/H) of the thickness H to the width W of the flat electric wire 2 is 4 or more. As a result, the flat electric wire 2 has a flatter shape, so that the flat electric wire 2 can be easily bent. Here, the flat electric wire 2 has a thickness H of 6.1 mm, a width W of 30 mm, and a ratio (W/H) thereof of about 4.9. The ratio (Wd/Hd) between the thickness (maximum thickness) Hd and the width (maximum width) Wd of the conductor 21 is also preferably four times or more.

（端子３）
端子３は、平型電線２の少なくとも一方の端部に設けられる。図１（ａ）では、平型電線２の両方の端部に端子３を設けた場合を示している。端子３は、絶縁体２２の端部から露出された導体２１の端部に加締め等の固定方法によって固定される固定部（以下、加締め部）３１と、制御盤等の装置１１に設けられた電極１１ａ（図２（ａ）参照）等の被接続部材にボルト等で固定するための平板状の接続部３２と、を一体に有する圧着端子である。なお、端子３を導体２１に加締め固定以外の方法で固定してもよい。 (Terminal 3)
A terminal 3 is provided on at least one end of the flat electric wire 2 . FIG. 1(a) shows a case where terminals 3 are provided at both ends of a flat electric wire 2. FIG. The terminal 3 has a fixing portion (hereinafter referred to as a crimping portion) 31 fixed to the end portion of the conductor 21 exposed from the end portion of the insulator 22 by a fixing method such as crimping, and a device 11 such as a control panel. It is a crimp terminal integrally having a plate-like connecting portion 32 for fixing to a connected member such as an electrode 11a (see FIG. 2(a)) with a bolt or the like. Note that the terminal 3 may be fixed to the conductor 21 by a method other than crimping.

加締め部３１は、筒状に形成されており、その内部に導体２１を挿入した状態で加締めることで、導体２１に固定されている。接続部３２は、加締め部３１から、平型電線２の長手方向における外方に向かって延出されている。接続部３２は、平板状に形成されており、その中央部には、ボルトを通すための貫通孔３２ａが形成されている。 The caulking portion 31 is formed in a cylindrical shape, and is fixed to the conductor 21 by caulking it with the conductor 21 inserted therein. The connecting portion 32 extends outward from the crimping portion 31 in the longitudinal direction of the flat electric wire 2 . The connecting portion 32 is formed in a flat plate shape, and a through hole 32a for passing a bolt is formed in the central portion thereof.

本実施の形態に係る端子付き平型電線１では、端子３は、接続部３２の法線方向が平型電線２の厚さ方向と交差するように設けられている。より具体的には、端子３は、接続部３２の法線方向が平型電線２の厚さ方向と直交するように（幅方向と平行になるように）設けられている。 In the flat electric wire 1 with a terminal according to the present embodiment, the terminal 3 is provided so that the normal direction of the connection portion 32 intersects the thickness direction of the flat electric wire 2 . More specifically, the terminal 3 is provided such that the normal direction of the connection portion 32 is orthogonal to the thickness direction of the flat electric wire 2 (parallel to the width direction).

これにより、図２（ａ）に示すように、平型電線２を厚さ方向に曲げて配線を行うことが可能になり、制御盤等の装置１１間の狭いスペースにも容易に配線できるようになる。なお、接続部３２の法線方向の平型電線２の厚さ方向に対する角度は、装置１１に設けられた電極１１ａの形状や向き等に応じて適宜調整可能である。これに対して、例えば、接続部３２の法線方向が平型電線２の厚さ方向と平行となるように端子３を設けた従来の端子付き平型電線１０の場合、図２（ｂ）に示すように、平型電線２を捩じるように配線しなければならない。そのため、平型電線２が蛇行して装置１１に干渉（接触）してしまいやすくなり、平型電線２が損傷を受けてしまうおそれが生じる。本実施の形態によれば、このような不具合を抑制し、装置１１間の狭いスペースにも容易に配線することが可能である。 As a result, as shown in FIG. 2(a), it becomes possible to wire by bending the flat wire 2 in the thickness direction, so that wiring can be easily performed in a narrow space between devices 11 such as a control panel. become. The angle of the normal direction of the connection portion 32 with respect to the thickness direction of the flat electric wire 2 can be appropriately adjusted according to the shape and orientation of the electrode 11 a provided in the device 11 . On the other hand, for example, in the case of the conventional flat electric wire 10 with a terminal in which the terminal 3 is provided so that the normal direction of the connecting portion 32 is parallel to the thickness direction of the flat electric wire 2, FIG. , the flat electric wire 2 must be twisted. As a result, the flat electric wire 2 is likely to meander and interfere with (contact with) the device 11, and the flat electric wire 2 may be damaged. According to the present embodiment, such problems can be suppressed, and wiring can be easily performed even in a narrow space between devices 11 .

すなわち、接続部３２の法線方向の平型電線２の厚さ方向に対する角度（＝接続部３２の法線方向と平型電線２の厚さ方向とのなす角度）が、接続部３２の法線方向と平型電線２の厚さ方向とが直交する場合を９０度とし、接続部３２の法線方向と平型電線２の厚さ方向とが平行となる場合を０度とすると、端子３は、上記角度が０度よりも大きく９０度以下の範囲となるように接続部３２の向きを調整することが可能である。これにより、端子付き平型電線１は、図２（ａ）に示すように、配線時に蛇行や捩れが生じにくくなり、装置１１に設けられた電極１１ａの形状や向き等に応じた配線が可能となる。 That is, the angle between the normal direction of the connecting portion 32 and the thickness direction of the flat wire 2 (=the angle between the normal direction of the connecting portion 32 and the thickness direction of the flat wire 2) is the normal to the connecting portion 32. Assuming that the wire direction and the thickness direction of the flat wire 2 are orthogonal to each other is 90 degrees, and that the normal direction of the connection portion 32 and the thickness direction of the flat wire 2 are parallel to each other is 0 degrees, the terminal 3, it is possible to adjust the orientation of the connecting portion 32 so that the angle is in the range of greater than 0 degrees and less than or equal to 90 degrees. As a result, as shown in FIG. 2(a), the terminal-equipped flat wire 1 is less prone to meandering and twisting during wiring, and wiring can be performed according to the shape and orientation of the electrodes 11a provided in the device 11. becomes.

（熱収縮チューブ４、平型電線２の端部の形状）
熱収縮チューブ４は、平型電線２の絶縁体２２から端子３の加締め部３１にかけて、その周囲を一括して覆うように設けられている。より詳細には、熱収縮チューブ４は、絶縁体２２と端子３との間で露出された導体２１、端子３の加締め部３１の少なくとも一部、及び絶縁体２２の端部を一括して覆うように設けられている。熱収縮チューブ４は、露出した導体２１の周囲を覆って絶縁する役割と、水分や埃等が平型電線２内に侵入するのを抑制する役割とを果たしている。 (Heat-shrinkable tube 4, end shape of flat electric wire 2)
The heat-shrinkable tube 4 is provided from the insulator 22 of the flat electric wire 2 to the crimped portion 31 of the terminal 3 so as to cover the entire circumference thereof. More specifically, the heat-shrinkable tube 4 bundles together the conductor 21 exposed between the insulator 22 and the terminal 3, at least a portion of the crimped portion 31 of the terminal 3, and the end of the insulator 22. provided to cover. The heat-shrinkable tube 4 serves to cover and insulate the exposed conductor 21 and to prevent moisture, dust, etc. from entering the flat wire 2 .

本実施の形態では、平型電線２の絶縁体２２から露出させた導体２１を束ねて加締め部３１で固定しており、平型電線２における導体２１の幅Ｗｄよりも、加締め部３１における導体２１の幅が小さくなっている。そして、熱収縮チューブ４は、露出された導体２１の周囲にできるだけ隙間なく密着するように設けられている。そのため、絶縁体２２と端子３との間において、熱収縮チューブ４の外形は、端子３に近づくほど幅が小さくなるテーパ形状となる。以下、絶縁体２２の端部と端子３との間の部分を非圧着部５と呼称する。このように構成することで、非圧着部５にて平型電線２の幅方向にも曲げることが可能になるため、配線時に平型電線２の蛇行や捩れを発生しにくくすることが可能になり、より配線作業が容易になる。また、露出された導体２１の周囲に密着するように十分に熱収縮チューブ４を収縮させることで、曲げた際等に熱収縮チューブ４が絶縁体２２の表面から浮いてしまうことが生じてしまったり、熱収縮チューブ４に位置ずれが生じてしまったりすることを抑制できる。なお、本実施の形態では、熱収縮チューブ４内に接着剤は充填されない。 In this embodiment, the conductors 21 exposed from the insulator 22 of the flat electric wire 2 are bundled and fixed by the caulking portion 31, and the width Wd of the conductor 21 in the flat electric wire 2 is larger than the width Wd of the conductor 21. , the width of the conductor 21 is reduced. The heat-shrinkable tube 4 is provided around the exposed conductor 21 so as to be in close contact therewith as much as possible. Therefore, between the insulator 22 and the terminal 3 , the outer shape of the heat-shrinkable tube 4 has a tapered shape in which the width decreases toward the terminal 3 . A portion between the end portion of the insulator 22 and the terminal 3 is hereinafter referred to as a non-crimping portion 5 . With this configuration, it is possible to bend the flat electric wire 2 in the width direction at the non-crimping portion 5, so that the flat electric wire 2 is less likely to meander or twist during wiring. This makes the wiring work easier. In addition, by sufficiently shrinking the heat shrinkable tube 4 so as to be in close contact with the periphery of the exposed conductor 21, the heat shrinkable tube 4 may float from the surface of the insulator 22 when bent. It is possible to prevent the heat-shrinkable tube 4 from getting loose and the heat-shrinkable tube 4 from being misaligned. In this embodiment, the heat-shrinkable tube 4 is not filled with an adhesive.

非圧着部５を曲げやすくし配線作業をより容易にするために、非圧着部５の長さ（すなわち、絶縁体２２の端部から端子３までの平型電線２の長手方向に沿った長さ）Ｌは、なるべく長くすることが望ましい。また、非圧着部５の長さＬが短すぎると、導体２１を束ねる際に平型電線２が長手方向からみて弓なりに湾曲するように撓んでしまいやすくなる。その結果、熱収縮チューブ４を設けた際に熱収縮チューブ４と絶縁体２２との間に隙間が生じてしまい、当該隙間から水分や埃が侵入しやすくなり接続信頼性が低下するおそれもある。そのため、非圧着部５の長さＬは、少なくとも、平型電線２の幅Ｗ以上であるとよい。 The length of the non-crimped portion 5 (i.e., the length along the longitudinal direction of the flat wire 2 from the end of the insulator 22 to the terminal 3 is adjusted to facilitate the bending of the non-crimped portion 5 and facilitate the wiring work. ) It is desirable to make L as long as possible. Also, if the length L of the non-crimping portion 5 is too short, the flat electric wire 2 tends to bend into a bow shape when viewed from the longitudinal direction when the conductors 21 are bundled. As a result, when the heat-shrinkable tube 4 is provided, a gap is formed between the heat-shrinkable tube 4 and the insulator 22, and moisture and dust are likely to enter through the gap, which may reduce connection reliability. . Therefore, it is preferable that the length L of the non-crimping portion 5 is at least equal to or greater than the width W of the flat electric wire 2 .

（変形例）
図３（ａ），（ｂ）は、平型電線２の一変形例を示す断面図である。図３（ａ），（ｂ）に示すように、平型電線２は、導体２１の周囲に設けられた形状保持用の帯状あるいは線状の形状保持部材２３をさらに有してもよい。 (Modification)
3(a) and 3(b) are sectional views showing a modified example of the flat electric wire 2. FIG. As shown in FIGS. 3A and 3B, the flat electric wire 2 may further have a belt-shaped or linear shape-retaining member 23 provided around the conductor 21 for shape retention.

図３（ａ）では、線状の形状保持部材２３ａを用いた場合を示しており、幅方向において導体２１を挟み込むように一対の形状保持部材２３ａが配置されている。線状の形状保持部材２３ａとしては、例えば、軟銅線やアルミニウム線等を用いることができる。なお、使用する形状保持部材２３ａの本数や配置位置は図示のものに限定されない。 FIG. 3A shows a case where linear shape retaining members 23a are used, and a pair of shape retaining members 23a are arranged so as to sandwich the conductor 21 in the width direction. As the linear shape retaining member 23a, for example, an annealed copper wire, an aluminum wire, or the like can be used. The number and arrangement positions of the shape retaining members 23a to be used are not limited to those shown in the drawing.

図３（ｂ）では、帯状の形状保持部材２３ｂを用いた場合を示しており、厚さ方向において導体２１と隣り合うように形状保持部材２３ｂが配置されている。帯状の形状保持部材２３ｂとしては、例えば銅板を用いることができる。 FIG. 3(b) shows a case where a belt-shaped shape retaining member 23b is used, and the shape retaining member 23b is arranged so as to be adjacent to the conductor 21 in the thickness direction. For example, a copper plate can be used as the belt-like shape retaining member 23b.

形状保持部材２３を有することにより、所望の形状に平型電線２を折り曲げた状態で形状保持することが可能となり、所望の配線レイアウトに沿った配線がより容易になる。なお、図示の例では、形状保持部材２３は、導体２１と絶縁体２２との間に設けられており形状保持部材２３と導体２１とが接触しているが、これに限らず、導体２１と形状保持部材２３とが離間していてもよい（導体２１と形状保持部材２３との間に絶縁体２２が存在してもよい）。 By having the shape-retaining member 23, it becomes possible to retain the shape of the flat electric wire 2 in a state in which it is bent into a desired shape, thereby facilitating wiring along a desired wiring layout. In the illustrated example, the shape-retaining member 23 is provided between the conductor 21 and the insulator 22, and the shape-retaining member 23 and the conductor 21 are in contact with each other. The shape retaining member 23 may be spaced apart (the insulator 22 may exist between the conductor 21 and the shape retaining member 23).

（実施の形態の作用及び効果）
以上説明したように、本実施の形態に係る端子付き平型電線１では、平型電線２の厚さＨと幅Ｗとの比（Ｗ／Ｈ）が４以上であり、端子３は、接続部３２の法線方向が平型電線２の厚さ方向と交差するように設けられている。これにより、端子付き平型電線１は、平型電線２を厚さ方向に曲げやすくなり、かつ、制御盤等の装置１１間の狭い隙間にも平型電線２の蛇行や捩れが生じることなく配線でき、配線作業が容易になる。つまり、本実施の形態によれば、曲げやすく配線しやすい端子付き平型電線１を実現できる。また、装置１１間の電源供給用の配線材に用いられてきた従来のバスバと比較して、端子付き平型電線１は、様々な配線レイアウトに配線することが可能で、且つ汎用性も高いため、設備の更新等の際に低コストの配線材を提供することが可能である。 (Actions and effects of the embodiment)

As a result, the flat electric wire 2 with a terminal can be easily bent in the thickness direction, and the flat electric wire 2 can be prevented from meandering or twisting even in narrow gaps between devices 11 such as control panels. It can be wired, and the wiring work becomes easy. That is, according to the present embodiment, it is possible to realize the flat electric wire 1 with a terminal that is easy to bend and easy to wire.
