Description

本発明は、ワイヤハーネスに関する。   The present invention relates to a wire harness.

特許文献1に示されるように、車両に搭載される電力系の従来のワイヤハーネスは、三相交流の各相に対応する3本の絶縁電線又は単相交流に対応する2本の絶縁電線が束ねられた構造を備える。絶縁電線は、電流が流れる導電部とその導電部の周囲を覆う絶縁被覆とを備える。   As shown in Patent Document 1, a conventional electric wire harness mounted on a vehicle has three insulated wires corresponding to three-phase alternating current phases or two insulated wires corresponding to single-phase alternating currents. It has a bundled structure. The insulated wire includes a conductive part through which a current flows and an insulating coating that covers the periphery of the conductive part.

また、ハイブリッド自動車又は電気自動車などの電導車両に搭載される電力系のワイヤハーネスにおいては、大きな電流が流れたときの過剰な発熱を防止するために太い電線の採用が必要となる。   In addition, in a power system wire harness mounted on a conductive vehicle such as a hybrid vehicle or an electric vehicle, it is necessary to use a thick electric wire in order to prevent excessive heat generation when a large current flows.

特開2003−197037号公報Japanese Patent Laid-Open No. 2003-197037

しかしながら、太い電線が採用されたワイヤハーネスは、柔軟性に欠けて取り扱い性能が悪いという問題点を有している。さらに、太い電線が採用されたワイヤハーネスは、表皮効果による電流の伝送ロスが大きくなりやすいという問題点も有している。   However, a wire harness employing a thick electric wire has a problem that it lacks flexibility and has poor handling performance. Furthermore, a wire harness employing a thick electric wire has a problem that current transmission loss due to the skin effect tends to increase.

本発明は、電力系のワイヤハーネスにおいて、過剰な発熱を防止するために断面積の大きな導電部が採用された場合でも、柔軟性が確保されて取り扱い性能が損なわれず、かつ、表皮効果による電流の伝送ロスを回避できることを目的とする。   Even if a conductive part having a large cross-sectional area is employed to prevent excessive heat generation in a power wiring harness, the present invention ensures flexibility and does not impair handling performance, and the current due to the skin effect The purpose is to avoid transmission loss.

The wire harness according to the present invention includes a plurality of cylindrical power transmission units stacked from the inside to the outside, and further includes the following components.
(1) A 1st component is a conductive part which constitutes each power transmission part, and is a plurality of cylindrical conductive parts which are formed in the shape of a cylinder by combining a plurality of conducting wires, and have flexibility.
(2) A 2nd component is an insulation part which comprises each power transmission part, and is a some cylindrical insulation part which is formed in the cylinder shape which covers the outer periphery of a cylindrical electroconductive part, and has a softness | flexibility.
(3) The third component is a plurality of terminals provided for each power transmission unit and electrically connected to the cylindrical conductive unit.

また、本発明に係るワイヤハーネスが、さらに以下に示す構成要素を備えることも考えられる。
(4)第4の構成要素は、最も内側の送電部の一部の内側に内包され、送電部の形状を一定に保持する芯部材である。
It is also conceivable that the wire harness according to the present invention further includes the following constituent elements.
(4) The fourth component is a core member that is included inside a part of the innermost power transmission unit and holds the shape of the power transmission unit constant.

また、本発明に係るワイヤハーネスにおいて、芯部材が、送電部の断面形状を扁平に保持する扁平な棒状に形成されていることが考えられる。   In the wire harness according to the present invention, it is conceivable that the core member is formed in a flat bar shape that holds the cross-sectional shape of the power transmission unit flat.

また、本発明に係るワイヤハーネスにおいて、外側の筒状導電部よりも内側の筒状導電部の方が断面における導線の総断面積が大きく形成されていることが考えられる。   In the wire harness according to the present invention, it is conceivable that the inner cylindrical conductive portion has a larger total cross-sectional area in the cross section than the outer cylindrical conductive portion.

また、本発明に係るワイヤハーネスが、さらに以下に示す構成要素を備えることも考えられる。
(5)第5の構成要素は、最も内側の送電部の内側に内包された絶縁電線である。
It is also conceivable that the wire harness according to the present invention further includes the following constituent elements.
(5) The fifth component is an insulated wire enclosed inside the innermost power transmission unit.

また、本発明に係るワイヤハーネスにおいて、筒状導電部が、複数の導線が編まれて筒状に形成され柔軟性を有する編組線からなることが考えられる。   In the wire harness according to the present invention, it is conceivable that the cylindrical conductive portion is formed of a braided wire having a flexibility by forming a plurality of conductive wires into a cylindrical shape.

また、本発明に係るワイヤハーネスが、さらに以下に示す構成要素を備えることも考えられる。
(6)第6の構成要素は、最も外側の送電部の外側を覆う筒状の編組線からなるシールド部材である。
It is also conceivable that the wire harness according to the present invention further includes the following constituent elements.
(6) A 6th component is a shield member which consists of a cylindrical braided wire which covers the outer side of the outermost power transmission part.

本発明に係るワイヤハーネスにおいて、筒状導電部は、例えば編組線からなる部分であり、複数の導線が組み合わされて筒状に形成され柔軟性を有する。そのため、筒状導電部が、過剰な発熱を防止するために大きな断面積で形成された場合でも、柔軟性が確保されて取り扱い性能が損なわれない。また、筒状導電部は、中空の構造を有するため表皮効果による電流の伝送ロスが生じにくい。   In the wire harness according to the present invention, the cylindrical conductive portion is a portion made of, for example, a braided wire, and is formed into a cylindrical shape by combining a plurality of conductive wires and has flexibility. Therefore, even when the cylindrical conductive portion is formed with a large cross-sectional area to prevent excessive heat generation, flexibility is ensured and handling performance is not impaired. In addition, since the cylindrical conductive portion has a hollow structure, current transmission loss due to the skin effect is unlikely to occur.

また、車両に搭載されるワイヤハーネスにおいて、一部分が予め定められた配線経路に沿う形状で保持され、他の部分が柔軟性を有することにより、ワイヤハーネスの敷設がより容易となる場合がある。そのような場合、本発明に係るワイヤハーネスが、送電部の形状を一定に保持する芯部材をさらに備えれば、敷設の取り扱い性能がより高まり好適である。   Moreover, in the wire harness mounted in a vehicle, a part is hold | maintained in the shape along a predetermined wiring path | route, and laying of a wire harness may become easier because another part has a softness | flexibility. In such a case, if the wire harness according to the present invention further includes a core member that keeps the shape of the power transmission unit constant, it is preferable that the handling performance of the laying is further increased.

また、本発明に係るワイヤハーネスが、送電部の断面形状を扁平に保持する扁平な棒状の芯部材を備えれば、送電部を高さの低い隙間に敷設することが容易となる。   Moreover, if the wire harness which concerns on this invention is provided with the flat rod-shaped core member which hold | maintains the cross-sectional shape of a power transmission part flat, it will become easy to lay a power transmission part in the clearance gap with low height.

また、本発明に係るワイヤハーネスにおいて、外側の筒状導電部よりも内側の筒状導電部の方が放熱性が悪い。そのため、外側の筒状導電部よりも内側の筒状導電部の方が断面における導線の総断面積が大きく形成されていることが望ましい。これにより、複数の筒状導電部各々の熱バランスが均一化され、一部の筒状導電部のみが過剰に高温化することを防止できる。   Moreover, in the wire harness according to the present invention, the inner cylindrical conductive portion is less heat radiating than the outer cylindrical conductive portion. For this reason, it is desirable that the inner cylindrical conductive portion of the inner cylindrical conductive portion has a larger total cross-sectional area in the cross section than the outer cylindrical conductive portion. Thereby, the thermal balance of each of the plurality of cylindrical conductive parts is made uniform, and only a part of the cylindrical conductive parts can be prevented from being excessively heated.

また、本発明に係るワイヤハーネスが、送電部の内側に内包された絶縁電線を備えれば、その絶縁電線は、筒状導電部に印加される電圧よりも低い電圧が印加される信号系の電線として利用可能である。これにより、電力系の送電部と信号系の絶縁電線とを効率的に配線することが可能となる。   In addition, if the wire harness according to the present invention includes an insulated wire contained inside the power transmission unit, the insulated wire has a signal system to which a voltage lower than the voltage applied to the cylindrical conductive unit is applied. It can be used as an electric wire. Accordingly, it is possible to efficiently wire the power transmission unit and the signal insulated wire.

また、本発明に係るワイヤハーネスが、送電部の外側を覆う筒状の編組線からなるシールド部材を備えれば、ワイヤハーネスの柔軟性を損なうことなく送電部のシールドが可能となる。   Moreover, if the wire harness which concerns on this invention is equipped with the shielding member which consists of a cylindrical braided wire which covers the outer side of a power transmission part, the power transmission part can be shielded without impairing the flexibility of a wire harness.

Each of the following embodiments is an example embodying the present invention, and is not an example of limiting the technical scope of the present invention.

<第1実施形態>
まず、図1から図4を参照しつつ、本発明の第1実施形態に係るワイヤハーネス1の構成について説明する。図1に示されるように、ワイヤハーネス1は、ケーブル部10と、ケーブル部10の両端に設けられた接続部50とを備える。また、ケーブル部10は、予め定められた形状に保持された第1ケーブル部11と、一定形状に保持されず柔軟性を有する第2ケーブル部12とを含む。図1は、第1ケーブル部11の断面図を含む斜視図であり、図2は、第2ケーブル部12の断面図を含む斜視図である。
<First Embodiment>
First, the configuration of the wire harness 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 4. As shown in FIG. 1, the wire harness 1 includes a cable portion 10 and connection portions 50 provided at both ends of the cable portion 10. Moreover, the cable part 10 contains the 1st cable part 11 hold | maintained at the predetermined shape, and the 2nd cable part 12 which is not hold | maintained at a fixed shape but has flexibility. FIG. 1 is a perspective view including a cross-sectional view of the first cable portion 11, and FIG. 2 is a perspective view including a cross-sectional view of the second cable portion 12.

<ケーブル部>
図1及び図2に示されるように、ケーブル部10は、内側から外側へ重ねられた3つの筒状の送電部を備える。各送電部は、筒状導電部2と筒状絶縁部3とにより構成されている。以下、筒状導電部2と筒状絶縁部3とを併せて送電部2・3と記載する。また、3つの筒状導電部2各々のことを、内側から外側へ順に第1筒状導電部21、第2筒状導電部22及び第3筒状導電部23と称する。同様に、3つの筒状絶縁部3各々のことを、内側から外側へ順に第1筒状絶縁部31、第2筒状絶縁部32及び第3筒状絶縁部33と称する。
<Cable part>
As shown in FIGS. 1 and 2, the cable unit 10 includes three cylindrical power transmission units stacked from the inside to the outside. Each power transmission unit includes a cylindrical conductive unit 2 and a cylindrical insulating unit 3. Hereinafter, the cylindrical conductive part 2 and the cylindrical insulating part 3 are collectively referred to as a power transmission part 2. Each of the three cylindrical conductive parts 2 is referred to as a first cylindrical conductive part 21, a second cylindrical conductive part 22, and a third cylindrical conductive part 23 in order from the inside to the outside. Similarly, each of the three cylindrical insulating portions 3 is referred to as a first cylindrical insulating portion 31, a second cylindrical insulating portion 32, and a third cylindrical insulating portion 33 in order from the inside to the outside.

即ち、ケーブル部10において、第1筒状絶縁部31は第1筒状導電部21の外周を覆って形成され、第2筒状導電部22は第1筒状絶縁部31の外周を覆って形成され、第2筒状絶縁部32は第2筒状導電部22の外周を覆って形成され、第3筒状導電部23は第2筒状絶縁部32の外周を覆って形成され、第3筒状絶縁部33は第3筒状導電部23の外周を覆って形成されている。   That is, in the cable part 10, the first cylindrical insulating part 31 is formed so as to cover the outer periphery of the first cylindrical conductive part 21, and the second cylindrical conductive part 22 covers the outer periphery of the first cylindrical insulating part 31. The second cylindrical insulating part 32 is formed so as to cover the outer periphery of the second cylindrical conductive part 22, and the third cylindrical conductive part 23 is formed so as to cover the outer periphery of the second cylindrical insulating part 32. The three cylindrical insulating portions 33 are formed so as to cover the outer periphery of the third cylindrical conductive portion 23.

筒状導電部2は、送電部2・3各々の一部を構成し、複数の導線が組み合わされて筒状に形成された導電部である。筒状導電部2は、複数の導線が筒状に組み合わされた構造を有するため、柔軟性を有し、曲げること及び押し潰して扁平な形状へ変形させることが容易である。例えば、筒状導電部2は、軟銅の導線が編まれて筒状に形成された編組線などである。   The cylindrical conductive part 2 is a conductive part that forms a part of each of the power transmission units 2 and 3 and is formed into a cylindrical shape by combining a plurality of conductive wires. Since the cylindrical conductive part 2 has a structure in which a plurality of conducting wires are combined in a cylindrical shape, it has flexibility, and can be easily bent and crushed to be deformed into a flat shape. For example, the cylindrical conductive portion 2 is a braided wire formed into a cylindrical shape by knitting an annealed copper conductor.

各筒状導電部2は、電動車両において三相モータとインバータ回路とを接続し、高い電圧が印加されることにより大きな電流が流れる電力線である。即ち、3つの筒状導電部2は、三相交流における各相の電流を伝送する。そのため、3つの筒状導電部2各々の断面における導線の総断面積は、過剰に発熱しない程度に十分に大きく形成されている。以下の説明において、筒状導電部2各々の断面における導線の総断面積のことを導線総断面積と称する。   Each cylindrical conductive portion 2 is a power line that connects a three-phase motor and an inverter circuit in an electric vehicle and through which a large current flows when a high voltage is applied. That is, the three cylindrical conductive parts 2 transmit the current of each phase in the three-phase alternating current. Therefore, the total cross-sectional area of the conducting wire in the cross section of each of the three cylindrical conductive portions 2 is sufficiently large so as not to generate excessive heat. In the following description, the total cross-sectional area of the conducting wire in each cross section of the cylindrical conductive portion 2 is referred to as a conducting wire total cross-sectional area.

本実施形態においては、外側の筒状導電部2よりも内側の筒状導電部2の方が導線総断面積が大きく形成されている。即ち、第3筒状導電部23の導線総断面積が最も小さく、第2筒状導電部22の導線総断面積は、第3筒状導電部23の導線総断面積よりも大きく、第1筒状導電部21の導線総断面積は、第2筒状導電部22の導線総断面積よりも大きい。   In the present embodiment, the inner cylindrical conductive portion 2 is formed to have a larger total cross-sectional area than the outer cylindrical conductive portion 2. That is, the total lead cross-sectional area of the third cylindrical conductive portion 23 is the smallest, the total lead cross-sectional area of the second cylindrical conductive portion 22 is larger than the total lead cross-sectional area of the third cylindrical conductive portion 23, The conducting wire total cross-sectional area of the cylindrical conductive part 21 is larger than the conducting wire total cross-sectional area of the second cylindrical conductive part 22.

また、筒状絶縁部3は、送電部2・3各々の一部を構成し、筒状導電部2の外周を覆う筒状に形成され柔軟性を有する絶縁部である。筒状絶縁部3は、その内側の筒状導電部2とその外側に存在する物とを電気的に絶縁する部材である。例えば、筒状絶縁部3は、ポリエチレン、塩化ビニル又はポリアミド系ナイロンなどの樹脂の筒状部材である。   Further, the cylindrical insulating portion 3 is a flexible insulating portion that forms a part of each of the power transmission units 2 and 3 and is formed in a cylindrical shape that covers the outer periphery of the cylindrical conductive portion 2. The cylindrical insulating part 3 is a member that electrically insulates the cylindrical conductive part 2 on the inner side from the object existing on the outer side. For example, the cylindrical insulating portion 3 is a cylindrical member made of resin such as polyethylene, vinyl chloride, or polyamide-based nylon.

また、図1に示されるように、ケーブル部10のうちの第1ケーブル部11は、最も内側の送電部2・3の内側に内包され、その送電部2・3の形状を一定に保持する芯部材4を備えている。   Further, as shown in FIG. 1, the first cable portion 11 of the cable portion 10 is included inside the innermost power transmission unit 2, 3, and the shape of the power transmission unit 2, 3 is held constant. A core member 4 is provided.

図4に示される斜視図は、芯部材4の一例を示す。図4に示される芯部材4は、その断面が扁平に形成された棒状の部材であり、直線状に延びる棒状に形成された直線部41と、ねじれて形成されたねじれ部42と、湾曲して形成された湾曲部43とを有する。   The perspective view shown in FIG. 4 shows an example of the core member 4. The core member 4 shown in FIG. 4 is a rod-like member having a flat cross section, and is linearly formed with a linear portion 41 formed into a linear shape, a twisted portion 42 formed by twisting, and a curved portion. And a curved portion 43 formed.

図4に示されるような芯部材4が、第1ケーブル部11における最も内側の送電部2・3の内側に配置されることにより、図3に示されるように、ケーブル部10の一部である第1ケーブル部11は、直線状の部分とねじれた部分と湾曲した部分とが連なった形状に保持される。さらに、芯部材4が扁平な棒状に形成されているため、図1に示されるように、第1ケーブル部11における3つの送電部2・3各々の断面形状は扁平に保持される。   As shown in FIG. 3, the core member 4 as shown in FIG. 4 is arranged inside the innermost power transmission units 2 and 3 in the first cable portion 11, so that a part of the cable portion 10 is used. The certain 1st cable part 11 is hold | maintained in the shape where the linear part, the twisted part, and the curved part continued. Furthermore, since the core member 4 is formed in a flat bar shape, as shown in FIG. 1, the cross-sectional shapes of the three power transmission units 2 and 3 in the first cable unit 11 are held flat.

一方、ケーブル部10のうちの第2ケーブル部12は、芯部材4を備えておらず、最も内側の送電部2・3の内側は空洞である。そのため、柔軟性を有する3つの送電部2・3が重ねられた構造を有する第2ケーブル部12は、全体として柔軟性が確保され、図3に示されるように、曲げること及び扁平な状態へ変形させることが容易である。   On the other hand, the 2nd cable part 12 of the cable parts 10 is not provided with the core member 4, and the inner side of the innermost power transmission part 2 * 3 is a cavity. Therefore, the 2nd cable part 12 which has the structure where the 3 power transmission parts 2 * 3 which have flexibility were piled up was secured as a whole, and as shown in FIG. 3, it bends and becomes a flat state. It is easy to deform.

<接続部>
図1に示されるように、ケーブル部10の両端に設けられた各接続部50は、3つの送電部2・3ごとに設けられた3つの端子5と、絶縁性の材料で構成された端子固定部6とを含む。
<Connection part>
As shown in FIG. 1, each connection part 50 provided at both ends of the cable part 10 includes three terminals 5 provided for each of the three power transmission parts 2 and 3 and terminals made of an insulating material. And a fixed portion 6.

3つの端子5は、モータ又はインバータ回路などの電装部品に対してネジ止めされる部分である。3つの端子5は、端子固定部6内においてそれぞれ独立して3つの筒状導電部2各々に対して電気的に接続されている。即ち、3つの端子5には、第1筒状導電部21と電気的に接続された第1端子51と、第2筒状導電部22と電気的に接続された第2端子52と、第3筒状導電部23と電気的に接続された第3端子55とが含まれる。例えば、3つの端子5は、端子固定部6内において3つの筒状導電部2各々に対して圧着又は溶着されている。   The three terminals 5 are parts that are screwed to electrical components such as a motor or an inverter circuit. The three terminals 5 are electrically connected to each of the three cylindrical conductive parts 2 independently in the terminal fixing part 6. That is, the three terminals 5 include a first terminal 51 electrically connected to the first cylindrical conductive portion 21, a second terminal 52 electrically connected to the second cylindrical conductive portion 22, and a first terminal The third cylindrical conductive portion 23 and a third terminal 55 electrically connected are included. For example, the three terminals 5 are crimped or welded to each of the three cylindrical conductive parts 2 in the terminal fixing part 6.

端子固定部6は、3つの端子5を予め定められた位置関係で保持する部材である。端子固定部6は、例えばポリアミド、ポリプロピレン、ポリブチレンテレフタレート、ABS樹脂又はポリエチレン又はそれらが混合された絶縁性の樹脂の成形部材である。   The terminal fixing portion 6 is a member that holds the three terminals 5 in a predetermined positional relationship. The terminal fixing portion 6 is a molded member made of, for example, polyamide, polypropylene, polybutylene terephthalate, ABS resin, polyethylene, or insulating resin in which they are mixed.

<効果>
ワイヤハーネス1において、筒状導電部2は、複数の導線が組み合わされて筒状に形成され柔軟性を有する。そのため、筒状導電部2が、過剰な発熱を防止するために大きな断面積で形成された場合でも、柔軟性が確保されて取り扱い性能が損なわれない。また、筒状導電部2は、中空の構造を有するため表皮効果による電流の伝送ロスが生じにくい。
<Effect>
In the wire harness 1, the cylindrical conductive portion 2 is formed into a cylindrical shape by combining a plurality of conductive wires and has flexibility. Therefore, even when the cylindrical conductive portion 2 is formed with a large cross-sectional area to prevent excessive heat generation, flexibility is ensured and handling performance is not impaired. Moreover, since the cylindrical conductive part 2 has a hollow structure, current transmission loss due to the skin effect is unlikely to occur.

また、ワイヤハーネス1において、第1ケーブル部11は、芯部材4によって予め定められた配線経路に沿う形状で保持され、第2ケーブル部12は、柔軟性を有する。これにより、ワイヤハーネス1の敷設の取り扱い性能がより高まる。   Moreover, in the wire harness 1, the 1st cable part 11 is hold | maintained in the shape in alignment with the wiring path predetermined by the core member 4, and the 2nd cable part 12 has a softness | flexibility. Thereby, the handling performance of laying the wire harness 1 is further increased.

また、ワイヤハーネス1の芯部材4は、送電部2・3の断面形状を扁平に保持する扁平な棒状であるため、第1ケーブル部11を高さの低い隙間に敷設することが容易となる。   Moreover, since the core member 4 of the wire harness 1 has a flat bar shape that holds the cross-sectional shape of the power transmission units 2 and 3 flat, it is easy to lay the first cable portion 11 in a gap having a low height. .

また、ワイヤハーネス1において、外側の第3筒状導電部23よりも内側の第2筒状導電部22の方が放熱性が悪い。これに対し、第2筒状導電部22が第3筒状導電部23よりも導線総断面積を大きく形成され、さらに、第1筒状導電部21が第2筒状導電部22よりも導線総断面積を大きく形成されている。その結果、3つの筒状導電部2各々の熱バランスが均一化され、一部の筒状導電部2のみが過剰に高温化することを防止できる。   Further, in the wire harness 1, the second cylindrical conductive part 22 on the inner side is worse in heat dissipation than the third cylindrical conductive part 23 on the outer side. On the other hand, the second cylindrical conductive portion 22 is formed to have a larger total cross-sectional area than the third cylindrical conductive portion 23, and the first cylindrical conductive portion 21 is more conductive than the second cylindrical conductive portion 22. The total cross-sectional area is formed large. As a result, the thermal balance of each of the three cylindrical conductive parts 2 is made uniform, and only a part of the cylindrical conductive parts 2 can be prevented from being excessively heated.

<第2実施形態>
次に、図5及び図6を参照しつつ、本発明の第2実施形態に係るワイヤハーネス1Aについて説明する。このワイヤハーネス1Aは、図1から図3に示されたワイヤハーネス1と比較して、一部の構成要素が追加された構成を有している。図5及び図6において、図1から図4に示される構成要素と同じ構成要素は、同じ参照符号が付されている。以下、ワイヤハーネス1Aにおけるワイヤハーネス1と異なる点についてのみ説明する。
Second Embodiment
Next, a wire harness 1A according to a second embodiment of the present invention will be described with reference to FIGS. This wire harness 1A has a configuration in which some components are added as compared to the wire harness 1 shown in FIGS. 5 and 6, the same constituent elements as those shown in FIGS. 1 to 4 are denoted by the same reference numerals. Hereinafter, only different points of the wire harness 1A from the wire harness 1 will be described.

図5は、ワイヤハーネス1Aの一部である第1ケーブル部11の断面図を含む斜視図であり、図6は、ワイヤハーネス1Aの一部である第2ケーブル部12の断面図を含む斜視図である。ワイヤハーネス1Aは、第1ケーブル部11を一定の形状に保持する芯部材4Aを備えている。この芯部材4Aは、ワイヤハーネス1における芯部材4に相当する。   5 is a perspective view including a cross-sectional view of the first cable portion 11 that is a part of the wire harness 1A, and FIG. 6 is a perspective view including a cross-sectional view of the second cable portion 12 that is a part of the wire harness 1A. FIG. The wire harness 1A includes a core member 4A that holds the first cable portion 11 in a fixed shape. The core member 4 </ b> A corresponds to the core member 4 in the wire harness 1.

ワイヤハーネス1Aは、ワイヤハーネス1Aが備える構成に加え、最も内側の送電部2・3の内側、即ち、第1筒状導電部21の内側に内包された複数の絶縁電線7を備えている。図5及び図6に示される例では、3本の絶縁電線7が第1筒状導電部21の内側に内包されているが、1本の絶縁電線7、2本の絶縁電線7又は4本以上の絶縁電線7が、第1筒状導電部21の内側に内包される例も考えられる。   The wire harness 1 </ b> A includes a plurality of insulated wires 7 included in the innermost power transmission units 2, 3, i.e., the first cylindrical conductive unit 21, in addition to the configuration of the wire harness 1 </ b> A. In the example shown in FIGS. 5 and 6, three insulated wires 7 are included inside the first cylindrical conductive portion 21, but one insulated wire 7, two insulated wires 7, or four. An example in which the above insulated wire 7 is included inside the first cylindrical conductive portion 21 is also conceivable.

絶縁電線7は、軟銅の撚り線からなる芯線とその芯線の周囲を覆う筒状の絶縁被覆とを有する電線である。この絶縁電線7は、筒状導電部2に印加される電圧よりも低い電圧が印加され、筒状導電部2に流れる電流よりも十分小さな電流が流れる信号系の電線である。   The insulated electric wire 7 is an electric wire having a core wire made of a stranded copper wire and a cylindrical insulating coating covering the periphery of the core wire. The insulated wire 7 is a signal-type wire to which a voltage lower than the voltage applied to the cylindrical conductive portion 2 is applied and a current sufficiently smaller than the current flowing through the cylindrical conductive portion 2 flows.

また、図5に示されるように、ワイヤハーネス1の芯部材4Aには、絶縁電線7が嵌め入れられる溝44が形成されている。これにより、絶縁電線7は、第1ケーブル部11内において一定の位置に保持される。   Further, as shown in FIG. 5, the core member 4 </ b> A of the wire harness 1 is formed with a groove 44 into which the insulated wire 7 is fitted. Thereby, the insulated wire 7 is held at a fixed position in the first cable portion 11.

<効果>
ワイヤハーネス1Aが採用されることにより、ワイヤハーネス1が採用される場合と同様の効果が得られる。さらに、ワイヤハーネス1Aは、送電部2・3の内側に内包された信号系の絶縁電線7を備える。そのため、電力系の送電部2・3と信号系の絶縁電線7とを効率的に配線することが可能となる。
<Effect>
By adopting the wire harness 1A, the same effect as that obtained when the wire harness 1 is employed can be obtained. Furthermore, the wire harness 1 </ b> A includes a signal-type insulated wire 7 included inside the power transmission units 2 and 3. Therefore, it is possible to efficiently wire the power transmission units 2 and 3 and the signal insulated wires 7.

<第3実施形態>
次に、図7を参照しつつ、本発明の第3実施形態に係るワイヤハーネス1Bについて説明する。このワイヤハーネス1Bは、図1から図3に示されたワイヤハーネス1と比較して、芯部材4と形状が異なる芯部材4Aを備える点、及び端子固定部6と形状が異なる端子固定部6Aを備える点のみが異なる。図7において、図1から図4に示される構成要素と同じ構成要素は、同じ参照符号が付されている。以下、ワイヤハーネス1Bにおけるワイヤハーネス1と異なる点についてのみ説明する。
<Third Embodiment>

The wire harness 1B includes a core member 4A having a shape different from that of the core member 4 and a terminal fixing portion 6A having a shape different from that of the terminal fixing portion 6 as compared with the wire harness 1 shown in FIGS. The only difference is that 7, the same components as those shown in FIGS. 1 to 4 are given the same reference numerals. Hereinafter, only different points from the wire harness 1 in the wire harness 1B will be described.

ワイヤハーネス1Bにおいて、第1ケーブル部11内に配置される芯部材4Aは、直線状に延びる棒状に形成された直線部41と、湾曲して形成された湾曲部43とを有する。しかしながら、芯部材4Aにはねじれ部42は形成されていない。このような形状の芯部材4Aも本発明に係るワイヤハーネスに採用される芯部材の一例である。   In the wire harness 1 </ b> B, the core member 4 </ b> A disposed in the first cable portion 11 includes a straight portion 41 that is formed in a rod shape that extends linearly, and a curved portion 43 that is curved. However, the twist part 42 is not formed in the core member 4A. The core member 4A having such a shape is also an example of the core member employed in the wire harness according to the present invention.

また、ワイヤハーネス1Bの端部には接続部50Aが設けられている。接続部50Aを構成する端子固定部6Aは、複数の端子5をそれらが並列する状態で保持する。このような形状の端子固定部6Aも本発明に係るワイヤハーネスに採用される端子固定部の一例である。   Moreover, the connection part 50A is provided in the edge part of the wire harness 1B. The terminal fixing portion 6A constituting the connection portion 50A holds the plurality of terminals 5 in a state where they are arranged in parallel. The terminal fixing portion 6A having such a shape is also an example of the terminal fixing portion employed in the wire harness according to the present invention.
