Description

本発明は、複合ケーブル及び複合ハーネスに関し、特に、自動車等の車両において車輪側と車体側とを接続する複合ケーブル及び複合ハーネスに関する。 The present invention relates to a composite cable and a composite harness, and particularly to a composite cable and a composite harness that connect a wheel side and a vehicle body side in a vehicle such as an automobile.

近年、自動車等の車両において、電動式の制動装置が用いられている。 In recent years, electric braking devices have been used in vehicles such as automobiles.

電動式の制動装置としては、電気機械式ブレーキ（Electro-Mechanical Brake、ＥＭＢ）や、電動パーキングブレーキ（Electric Parking Brake、ＥＰＢ）が知られている。 As an electric braking device, an electro-mechanical brake (EMB) and an electric parking brake (EPB) are known.

電気機械式ブレーキは、単に電動ブレーキあるいは電気ブレーキとも呼称されるものであり、運転者によるブレーキペダルの操作量（踏力又は変位量）に応じて、車両の各車輪に備えられた専用の電気モータの回転駆動力を制御し、当該電気モータにより駆動されるピストンによりブレーキパッドを車輪のディスクロータに押し付けることにより、運転者の意図に応じた制動力を発生させるように構成されている。 The electromechanical brake is also simply referred to as an electric brake or an electric brake, and a dedicated electric motor provided for each wheel of the vehicle according to the operation amount (pedal force or displacement amount) of the brake pedal by the driver. The rotational driving force is controlled and the piston driven by the electric motor pushes the brake pad against the disc rotor of the wheel to generate a braking force according to the driver's intention.

電動パーキングブレーキは、車両の停止後に運転者がパーキングブレーキ作動スイッチを操作することにより、車両の各車輪に備えられた専用の電気モータを駆動させて、当該電気モータにより駆動されるピストンによりブレーキパッドを車輪のディスクロータに押し付けた状態とし、制動力を発生させるように構成されている。 In the electric parking brake, a driver operates a parking brake operation switch after the vehicle is stopped to drive a dedicated electric motor provided on each wheel of the vehicle, and a brake pad is driven by a piston driven by the electric motor. Is pressed against the disc rotor of the wheel to generate a braking force.

また、近年の車両においては、走行中の車輪の回転速度を検出するＡＢＳ（Anti-lock Brake System）センサや、タイヤの空気圧を検出する空気圧センサ、温度センサなどのセンサ類が車輪に搭載されることが多い。 Further, in recent vehicles, sensors such as an ABS (Anti-lock Brake System) sensor that detects the rotational speed of a running wheel, an air pressure sensor that detects the tire air pressure, and a temperature sensor are mounted on the wheel.

そこで、車輪に搭載されたセンサ用の信号線や電気機械式ブレーキの制御用の信号線と、電気機械式ブレーキや電動パーキングブレーキ用の電気モータに電力を供給する電源線とを共通のシースに収容した複合ケーブルを用い、車輪側と車体側とを接続することが行われている。この複合ケーブルの端部にコネクタを一体に設けたものは、複合ハーネスと呼称されている。 Therefore, use a common sheath for the signal lines for the sensors mounted on the wheels and the signal lines for controlling the electromechanical brakes, and the power supply lines that supply power to the electric motors for the electromechanical brakes and electric parking brakes. The wheel side and the vehicle body side are connected using the accommodated composite cable. A composite harness in which a connector is integrally provided at an end of this composite cable is called a composite harness.

特許文献１では、複数の電線とその複数の電線を一括して被覆するシースとの間に、タルク粉体等の潤滑剤を介在させることで、電線とシース間の摩擦を低減し、屈曲時に電線にかかるストレスを低減して耐屈曲性を向上させた複合ケーブルが提案されている。 In Patent Document 1, by interposing a lubricant such as talc powder between a plurality of electric wires and a sheath that collectively covers the plurality of electric wires, friction between the electric wires and the sheath is reduced, and at the time of bending. A composite cable has been proposed in which stress applied to an electric wire is reduced to improve bending resistance.

［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]
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

（複合ケーブルを適用する車両の説明）
図１は、本実施の形態に係る複合ケーブルを用いた車両の構成を示すブロック図である。 (Explanation of vehicle to which composite cable is applied)
FIG. 1 is a block diagram showing a configuration of a vehicle using the composite cable according to the present embodiment.

図１に示すように、車両１００には、電動式の制動装置として、電動パーキングブレーキ（以下、ＥＰＢという）１０１が備えられている。 As shown in FIG. 1, a vehicle 100 is provided with an electric parking brake (hereinafter referred to as EPB) 101 as an electric braking device.

ＥＰＢ１０１は、ＥＰＢ用電気モータ１０１ａと、ＥＰＢ制御部１０１ｂと、を備えている。 The EPB 101 includes an EPB electric motor 101a and an EPB control unit 101b.

ＥＰＢ用電気モータ１０１ａは、車両１００の車輪１０２に搭載されている車輪側装置である。ＥＰＢ制御部１０１ｂは、車両１００の車体側装置であるＥＣＵ（電子制御ユニット）１０３に搭載されている。なお、ＥＰＢ制御部１０１ｂは、ＥＣＵ１０３以外のコントロールユニットに搭載されていてもよく、専用のハードウェアユニットに搭載されていてもよい。 The EPB electric motor 101a is a wheel side device mounted on the wheels 102 of the vehicle 100. The EPB control unit 101b is mounted on an ECU (electronic control unit) 103 which is a vehicle body side device of the vehicle 100. The EPB control unit 101b may be mounted on a control unit other than the ECU 103, or may be mounted on a dedicated hardware unit.

図示していないが、ＥＰＢ用電気モータ１０１ａには、ブレーキパッドが取り付けられたピストンが設けられており、当該ピストンをＥＰＢ用電気モータ１０１ａの回転駆動により移動させることで、ブレーキパッドを車輪１０２の車輪のディスクロータに押し付け、制動力を発生させるように構成されている。ＥＰＢ用電気モータ１０１ａには、ＥＰＢ用電気モータ１０１ａに駆動電流を供給するための電源線として１対の第３電線６が接続されている。 Although not shown, the EPB electric motor 101a is provided with a piston to which a brake pad is attached. The wheel is pressed against the disc rotor to generate a braking force. A pair of third electric wires 6 are connected to the EPB electric motor 101a as power supply lines for supplying a drive current to the EPB electric motor 101a.

ＥＰＢ制御部１０１ｂは、車両１００の停止時に、パーキングブレーキ作動スイッチ１０１ｃがオフ状態からオン状態に操作されたとき、所定時間（例えば１秒間）にわたってＥＰＢ用電気モータ１０１ａに駆動電流を出力することにより、ブレーキパッドを車輪１０２のディスクロータに押し付けた状態とし、車輪１０２に制動力を発生させるように構成されている。また、ＥＰＢ制御部１０１ｂは、パーキングブレーキ作動スイッチ１０１ｃがオン状態からオフ状態に操作されたとき、あるいは、アクセルペダルが踏込操作されたときに、ＥＰＢ用電気モータ１０１ａに駆動電流を出力し、ブレーキパッドを車輪のディスクロータから離間させて、車輪１０２への制動力を解除するように構成される。つまり、ＥＰＢ１０１の作動状態は、パーキングブレーキ作動スイッチ１０１ｃがオンされてから、パーキングブレーキ作動スイッチ１０１ｃがオフされるかアクセルペダルが踏み込まれるまで維持されるように構成されている。なお、パーキングブレーキ作動スイッチ１０１ｃは、レバー式又はペダル式のスイッチであってもよい。 The EPB control unit 101b outputs a drive current to the EPB electric motor 101a for a predetermined time (for example, 1 second) when the parking brake operation switch 101c is operated from the OFF state to the ON state when the vehicle 100 is stopped. The brake pad is pressed against the disc rotor of the wheel 102 to generate a braking force on the wheel 102. Further, the EPB control unit 101b outputs a drive current to the EPB electric motor 101a when the parking brake actuation switch 101c is operated from the ON state to the OFF state or when the accelerator pedal is stepped on, and the EPB control unit 101b brakes. The pad is separated from the disc rotor of the wheel to release the braking force on the wheel 102. That is, the operation state of the EPB 101 is configured to be maintained after the parking brake operation switch 101c is turned on until the parking brake operation switch 101c is turned off or the accelerator pedal is depressed. The parking brake operation switch 101c may be a lever type switch or a pedal type switch.

また、車両１００には、ＡＢＳ装置１０４が搭載されている。ＡＢＳ装置１０４は、ＡＢＳセンサ１０４ａと、ＡＢＳ制御部１０４ｂと、を備えている。 An ABS device 104 is mounted on the vehicle 100. The ABS device 104 includes an ABS sensor 104a and an ABS control unit 104b.

ＡＢＳセンサ１０４ａは、走行中の車輪１０２の回転速度を検出する回転速度検出センサであり、車輪１０２に搭載されている。ＡＢＳ制御部１０４ｂは、急停止時に車輪１０２がロックされないように、ＡＢＳセンサ１０４ａの出力に基づいて制動装置を制御し、車輪１０２の制動力を制御するものであり、ＥＣＵ１０３に搭載されている。ＡＢＳセンサ１０４ａには、信号線として１対の第１電線２が接続されている。 The ABS sensor 104a is a rotation speed detection sensor that detects the rotation speed of the running wheel 102, and is mounted on the wheel 102. The ABS control unit 104b controls the braking device based on the output of the ABS sensor 104a and controls the braking force of the wheels 102 so that the wheels 102 are not locked during a sudden stop, and is installed in the ECU 103. A pair of first electric wires 2 are connected as signal lines to the ABS sensor 104a.

また、車両１００の車輪１０２には、車輪１０２に設けられたタイヤ（不図示）の空気圧を検出する空気圧センサ１０８が設けられている。空気圧センサ１０８には、信号線として１対の第２電線４が接続されている。ＥＣＵ１０３には、空気圧センサ１０８の出力に基づいてタイヤの空気圧を検出する空気圧検出１０９が搭載されている。 Further, a wheel 102 of the vehicle 100 is provided with an air pressure sensor 108 that detects an air pressure of a tire (not shown) provided on the wheel 102. A pair of second electric wires 4 are connected to the air pressure sensor 108 as signal lines. The ECU 103 is equipped with an air pressure detector 109 that detects the tire air pressure based on the output of the air pressure sensor 108.

第１電線２と第２電線４と第３電線６とを一括してシース９（図２参照）で被覆したものが、本実施の形態に係る複合ケーブル１である。車輪１０２側から延出された複合ケーブル１は、車体１０５に設けられた中継ボックス１０６内にて電線群１０７に接続され、電線群１０７を介してＥＣＵ１０３やバッテリ（不図示）に接続されている。 The first electric wire 2, the second electric wire 4, and the third electric wire 6 are collectively covered with the sheath 9 (see FIG. 2) to form the composite cable 1 according to the present embodiment. The composite cable 1 extending from the wheel 102 side is connected to a wire group 107 in a relay box 106 provided in the vehicle body 105, and is connected to the ECU 103 and a battery (not shown) via the wire group 107. ..

図１では、図の簡略化のために１つの車輪１０２のみを示しているが、ＥＰＢ用電気モータ１０１ａ、ＡＢＳセンサ１０４ａ、及び空気圧センサ１０８は、車両１００の各車輪１０２に搭載されていてもよく、例えば、車両１００の前輪のみ、あるいは後輪のみに搭載されていてもよい。 Although only one wheel 102 is shown in FIG. 1 for simplification of the drawing, the EPB electric motor 101a, the ABS sensor 104a, and the air pressure sensor 108 may be mounted on each wheel 102 of the vehicle 100. Well, for example, it may be mounted only on the front wheels of the vehicle 100 or only on the rear wheels.

The wire used for the first central conductor 21 may have a diameter of 0.05 mm or more and 0.30 mm or less. If a wire having a diameter of less than 0.05 mm is used, sufficient mechanical strength may not be obtained and the bending resistance may be reduced. If a wire having a diameter of more than 0.30 mm is used, the composite cable 1 may be flexible. May deteriorate.

In order to make the outer diameter of the composite cable 1 close to a circular shape, the first electric wire 2 and the second electric wire 4 are It can be said that it is desirable to use a wire having about half the outer diameter of the three electric wires 6.

具体的には、第１電線２及び第２電線４としては、外径１．０ｍｍ以上１．８ｍｍ以下のものを用いることができる。ここでは、第１電線２として、第１中心導体２１の導体断面積が０．１３ｍｍ2以上０．３０ｍｍ2以下のものを用い、第２電線４として、第２中心導体４１の導体断面積が０．３０ｍｍ2以上０．５０ｍｍ2以下のものを用いた。本実施の形態では、第１電線２における導体断面積よりも第２電線４における導体断面積が大きくなるように設定したが、両電線２，４の導体断面積は同じであってもよい。複合ケーブル１の断面形状をより円形状に近づけるという観点からは、両電線２，４の外径は略等しくされること（例えば、両電線２，４の外径の差が電線２の外径の２０％以内であること）が望ましいといえる。 Specifically, as the first electric wire 2 and the second electric wire 4, those having an outer diameter of 1.0 mm or more and 1.8 mm or less can be used. Here, as the first electric wire 2, a conductor having a conductor cross-sectional area of the first center conductor 21 of 0.13 mm 2 or more and 0.30 mm 2 or less is used, and as the second electric wire 4, the conductor cross-sectional area of the second center conductor 41 is 0.30 mm 2 or more 0.50 mm 2 we used the following ones. In the present embodiment, the conductor cross-sectional area of the second electric wire 4 is set to be larger than the conductor cross-sectional area of the first electric wire 2, but the conductor cross-sectional areas of the two electric wires 2 and 4 may be the same. From the viewpoint of making the cross-sectional shape of the composite cable 1 closer to a circular shape, the outer diameters of both electric wires 2 and 4 should be substantially equal (for example, the difference between the outer diameters of both electric wires 2 and 4 is the outer diameter of the electric wire 2). Within 20% of).

第１対撚線３の撚りピッチＰ１、及び第２対撚線５の撚りピッチＰ２は、第１電線２や第２電線４の外径を考慮し、第１電線２や第２電線４に不要な負荷がかからない程度に設定するとよい。ここでは、両対撚線３，５の撚りピッチＰ１，Ｐ２を約３０ｍｍとしたが、対撚線３，５の撚りピッチＰ１，Ｐ２はこれに限定されるものではない。また、両対撚線３，５の撚りピッチＰ１，Ｐ２が互いに異なっていていてもよい。なお、第１対撚線３の撚りピッチＰ１とは、任意の第１電線２が第１対撚線３の周方向において同じ位置となる第１対撚線３の長手方向に沿った間隔である。また、第２対撚線５の撚りピッチＰ２とは、任意の第２電線４が第２対撚線５の周方向において同じ位置となる第２対撚線５の長手方向に沿った間隔である。 The twist pitch P1 of the first twisted pair wire 3 and the twist pitch P2 of the second twisted pair wire 5 are set to the first wire 2 and the second wire 4 in consideration of the outer diameters of the first wire 2 and the second wire 4. It should be set so that unnecessary load is not applied. Here, the twist pitches P1 and P2 of both twisted pair wires 3 and 5 are set to about 30 mm, but the twist pitches P1 and P2 of the twisted pair wires 3 and 5 are not limited to this. Further, the twist pitches P1 and P2 of the twisted pair wires 3 and 5 may be different from each other. In addition, the twist pitch P1 of the first twisted pair wire 3 is an interval along the longitudinal direction of the first twisted pair wire 3 where any first electric wire 2 is at the same position in the circumferential direction of the first twisted pair wire 3. is there. Further, the twist pitch P2 of the second twisted pair wire 5 is an interval along the longitudinal direction of the second twisted pair wire 5 in which any second electric wire 4 is located at the same position in the circumferential direction of the second twisted pair wire 5. is there.

集合体７は、第１対撚線３と、第２対撚線５と、１対の第３電線６とを撚り合わせて構成される。本実施の形態では、周方向において第１対撚線３と第２対撚線５との間に第３電線６が配置されている。図２（ａ）の断面においては、時計回り方向に、第２対撚線５、一方の第３電線６、第１対撚線３、他方の第３電線６が順次配置されている。 The aggregate 7 is formed by twisting the first twisted pair wire 3, the second twisted pair wire 5, and the pair of third electric wires 6. In the present embodiment, the third electric wire 6 is arranged between the first twisted pair wire 3 and the second twisted pair wire 5 in the circumferential direction. In the cross section of FIG. 2A, the second twisted pair 5, the one third wire 6, the first twisted pair 3, and the other third wire 6 are sequentially arranged in the clockwise direction.

なお、第３電線６を周方向に隣り合うように配置した場合（両対撚線３，５を隣り合うように配置した場合）には、集合体７の重心が集合体７の中心位置から大きくずれてしまい、この状態で両対撚線３，５と第３電線６とを撚り合わせて集合体７を構成すると、集合体７が全体的に捩れた状態となってしまう。そのため、直線状の複合ケーブル１を作製することが困難となり、また長手方向の一部において曲げにくい方向が発生するなどして、可撓性が低下してしまう問題も生じる。本実施の形態のように、周方向において第１対撚線３と第２対撚線５との間に第３電線６が配置される構成とすることで、直線状の複合ケーブル１を容易に実現可能となり、かつ、長手方向の一部において曲げにくい方向が発生するといった不具合を抑制して、可撓性の低下を抑制できる。 When the third electric wires 6 are arranged so as to be adjacent to each other in the circumferential direction (when the paired twisted wires 3 and 5 are arranged so as to be adjacent to each other), the center of gravity of the assembly 7 is changed from the center position of the assembly 7. If the twisted paired wires 3 and 5 and the third electric wire 6 are twisted together to form the aggregate 7, the aggregate 7 will be twisted as a whole. Therefore, it is difficult to manufacture the linear composite cable 1, and there is a problem that flexibility is deteriorated due to occurrence of a direction that is difficult to bend in a part of the longitudinal direction. As in the present embodiment, by arranging the third electric wire 6 between the first twisted pair wire 3 and the second twisted pair wire 5 in the circumferential direction, the linear composite cable 1 can be easily manufactured. In addition, it is possible to realize the above, and it is possible to suppress a defect that a direction that is difficult to bend occurs in a part of the longitudinal direction, and to suppress deterioration of flexibility.

さらに、本実施の形態では、第１対撚線３、第２対撚線５、１対の第３電線６、及びテープ部材８との間に、複合ケーブル１の長手方向に延びる糸状（繊維状）の複数の介在１０を配置し、両対撚線３，５及び第３電線６と共に撚り合わせることにより、集合体７を構成した。このため、複数の介在１０の撚り方向及び撚りピッチは、集合体７の撚り方向及び撚りピッチと同じになる。複数の介在１０は、両対撚線３，５と第３電線６とテープ部材８との間の隙間を埋めるように配置されており、集合体７の外周にテープ部材８を巻き付けた際の断面形状がより円形状に近づくようにしている。なお、複数の介在１０の一部は、対撚線３，５と第３電線６の間である谷間や、１対の第１電線２の間である谷間、あるいは１対の第２電線４の間である谷間にも配置されてもよい。 Further, in the present embodiment, a yarn shape (fiber) extending in the longitudinal direction of the composite cable 1 is provided between the first twisted pair wire 3, the second twisted pair wire 5, the pair of third wires 6, and the tape member 8. A plurality of interposers 10 of the shape) are arranged and twisted together with the paired twisted wires 3, 5 and the third electric wire 6 to form the assembly 7. Therefore, the twisting direction and the twisting pitch of the plurality of interpositions 10 are the same as the twisting direction and the twisting pitch of the aggregate 7. The plurality of interpositions 10 are arranged so as to fill the gaps between the pair of twisted wires 3, 5, the third electric wire 6, and the tape member 8, and when the tape member 8 is wound around the outer periphery of the assembly 7. The cross-sectional shape is made closer to a circular shape. In addition, a part of the plurality of interpositions 10 is a valley between the pair of twisted wires 3 and 5 and the third electric wire 6, a valley between the pair of first electric wires 2, or a pair of the second electric wires 4. It may also be arranged in a valley between them.

介在１０としては、ポリプロピレンヤーンや、スフ糸（レーヨンステープルファイバー）、アラミド繊維、ナイロン繊維、あるいは繊維系プラスチック等の繊維状体や、紙もしくは綿糸を用いることができる。また、図２（ａ）の横断面視において、介在１０の断面積は、第１電線２の断面積、第２電線４の断面積、及び第３電線６の断面積を合計した電線２，４，６の合計断面積よりも大きいとよい。 As the interposition 10, polypropylene yarn, soft yarn (rayon staple fiber), aramid fiber, nylon fiber, fibrous material such as fiber-based plastic, or paper or cotton yarn can be used. In addition, in the cross-sectional view of FIG. 2A, the cross-sectional area of the interposition 10 is the electric wire 2, which is the sum of the cross-sectional area of the first electric wire 2, the cross-sectional area of the second electric wire 4, and the cross-sectional area of the third electric wire 6. It is preferable that it is larger than the total cross-sectional area of 4, 6.

なお、ＥＰＢ１０１では、パーキングブレーキ作動スイッチ１０１ｃが操作された際に短時間駆動電流を供給するものであり、信号線として用いられる第１電線２や第２電線４へのノイズの影響が小さい。そこで、本実施の形態では、第３電線６や対撚線３，５の周囲に設けられるシールド導体を省略している。シールド導体を省略することで、シールド導体を設けた場合と比較して複合ケーブル１の外径を小さくすることができ、また部品点数を削減してコストを抑制することも可能になる。 The EPB 101 supplies a short-time drive current when the parking brake operation switch 101c is operated, and the influence of noise on the first electric wire 2 and the second electric wire 4 used as signal lines is small. Therefore, in the present embodiment, the shield conductor provided around the third electric wire 6 and the twisted pair wires 3 and 5 is omitted. By omitting the shield conductor, the outer diameter of the composite cable 1 can be reduced as compared with the case where the shield conductor is provided, and the number of parts can be reduced and the cost can be suppressed.

また、本実施の形態では、主に車両の停車後にＥＰＢ１０１へ駆動電流を供給する一対の第３電線６により、車両の走行時に電気信号を伝送する第１対撚線３と、同じく車両の走行時に電気信号を伝送する第２対撚線５と、を離間させている。これにより、対撚線３，５の周囲に設けられるシールド導体を省略したとしても、第１対撚線３と第２対撚線５との間のクロストークを低減することが可能となる。 Further, in the present embodiment, the first pair twisted wire 3 that transmits an electric signal when the vehicle is traveling is mainly driven by the pair of third electric wires 6 that supply the drive current to the EPB 101 after the vehicle is stopped, and the vehicle traveling is also the same. The second twisted pair wire 5, which sometimes transmits an electric signal, is separated from the second twisted wire 5. Thereby, even if the shield conductors provided around the twisted pair wires 3 and 5 are omitted, it is possible to reduce the crosstalk between the first twisted pair wire 3 and the second twisted pair wire 5.

なお、ここでは第３電線６がＥＰＢ用電気モータ１０１ａに駆動電流を供給するものである場合を説明しているが、第３電線６は、例えば、車輪１０２に設けられた電気機械式ブレーキ（以下、ＥＭＢという）の電気モータに駆動電流を供給するために用いられてもよい。この場合、第３電線６に駆動電流が頻繁に流れることになるため、信号線として用いられる第１電線２や第２電線４へのノイズの影響を抑制するために、対撚線３，５の周囲（あるいは各電線２，４の周囲）にシールド導体を設けることが望ましいといえる。 In addition, although the case where the third electric wire 6 supplies a drive current to the EPB electric motor 101a is described here, the third electric wire 6 is, for example, an electromechanical brake ( Hereinafter, referred to as EMB), may be used to supply drive current to an electric motor. In this case, since the drive current frequently flows through the third electric wire 6, in order to suppress the influence of noise on the first electric wire 2 and the second electric wire 4 used as signal lines, the twisted pair wires 3, 5 It can be said that it is desirable to provide a shield conductor around (or around each of the electric wires 2 and 4).

また、ここでは第１電線２がＡＢＳセンサ１０４ａ用の信号線であり、第２電線４が空気圧センサ１０８用の信号線である場合を説明しているが、第１電線２及び第２電線４は、車輪１０２に設けられる他のセンサ、例えば温度センサ等に用いられる信号線であってもよいし、車両１００の制振装置の制御に用いられるダンパ線であってもよく、さらにはＥＭＢ制御用の信号線（ＣＡＮケーブル等）であってもよい。 Further, here, the case where the first electric wire 2 is the signal wire for the ABS sensor 104a and the second electric wire 4 is the signal wire for the air pressure sensor 108 has been described, but the first electric wire 2 and the second electric wire 4 are described. May be a signal line used for another sensor provided on the wheel 102, for example, a temperature sensor or the like, a damper line used for controlling a vibration damping device of the vehicle 100, and further, an EMB control. It may be a signal line for use (CAN cable or the like).

集合体７全体の外径は、例えば、５ｍｍ〜９ｍｍ程度である。集合体７の撚りピッチＰ３は、集合体７の外径を考慮し、対撚線３，５と第３電線６に不要な負荷がかからない程度に設定するとよい。ここでは、集合体７の撚りピッチＰ３を約６０ｍｍとしたが、集合体７の撚りピッチＰ３はこれに限定されるものではない。なお、集合体７の撚りピッチＰ３とは、任意の対撚線３，５または第３電線６が集合体７の周方向において同じ位置となる集合体７の長手方向に沿った間隔である。 The outer diameter of the entire assembly 7 is, for example, about 5 mm to 9 mm. The twist pitch P3 of the assembly 7 is preferably set in consideration of the outer diameter of the assembly 7 so as not to apply an unnecessary load to the twisted pair wires 3, 5 and the third electric wire 6. Here, the twist pitch P3 of the aggregate 7 is set to about 60 mm, but the twist pitch P3 of the aggregate 7 is not limited to this. The twist pitch P3 of the aggregate 7 is an interval along the longitudinal direction of the aggregate 7 in which any pair of twisted wires 3, 5 or the third electric wire 6 is at the same position in the circumferential direction of the aggregate 7.

集合体７の周囲には、テープ部材８が螺旋状に巻き付けられており、テープ部材８は、テープ部材８が覆う全ての電線（１対の第１電線２、１対の第２電線４、及び１対の第３電線６）に接触している。テープ部材８は、集合体７とシース９との間に介在し、屈曲時に集合体７（電線２，４，６）とシース９間の摩擦を低減する役割を果たす。すなわち、テープ部材８を設けることで、従来のようにタルク粉体等の潤滑剤を用いることなく、電線２，４，６とシース９間の摩擦を低減し、屈曲時に電線２，４，６にかかるストレスを低減して、耐屈曲性を向上させることが可能になる。 A tape member 8 is spirally wound around the assembly 7, and the tape member 8 covers all the electric wires (the pair of first electric wires 2 and the pair of second electric wires 4, which are covered by the tape member 8). And a pair of third electric wires 6). The tape member 8 is interposed between the assembly 7 and the sheath 9 and plays a role of reducing friction between the assembly 7 (electric wires 2, 4, 6) and the sheath 9 when bent. That is, by providing the tape member 8, the friction between the electric wires 2, 4, 6 and the sheath 9 can be reduced without using a lubricant such as talc powder as in the conventional case, and the electric wires 2, 4, 6 can be bent. It is possible to reduce the stress applied to the body and improve the bending resistance.

テープ部材８としては、第１電線２の第１絶縁体２２、第２電線４の第２絶縁体４２、及び第３電線６の第３絶縁体６２に対して、滑りやすいもの（摩擦係数が小さいもの）を用いることが望ましく、例えば、不織布や紙、あるいは樹脂（樹脂フィルム等）からなるものを用いることができる。より具体的には、テープ部材８としては、テープ部材８と絶縁体２２，４２，６２間の摩擦係数（静摩擦係数）が、テープ部材８を設けなかった際におけるシース９と絶縁体２２，４２，６２間の摩擦係数（静摩擦係数）よりも小さい部材を用いるとよい。 The tape member 8 is slippery with respect to the first insulator 22 of the first electric wire 2, the second insulator 42 of the second electric wire 4, and the third insulator 62 of the third electric wire 6 (the friction coefficient is It is desirable to use a small one, and for example, a non-woven fabric, paper, or a resin (resin film) can be used. More specifically, as the tape member 8, the coefficient of friction (static friction coefficient) between the tape member 8 and the insulators 22, 42, 62 is the sheath 9 and the insulators 22, 42 when the tape member 8 is not provided. , 62, it is preferable to use a member having a smaller coefficient of friction (static coefficient of friction).

なお、テープ部材８としては、２層以上の積層構造となっているものも用いることができる。この場合、テープ部材８の集合体７と接触する面が、不織布、紙、樹脂層のいずれかからなるものを用いればよい。例えば、テープ部材８として、紙の一方の面に樹脂層を形成したものを用い、より摩擦係数が小さい樹脂層を集合体７側として巻き付けるように構成することもできる。 The tape member 8 may have a laminated structure of two or more layers. In this case, the surface of the tape member 8 that comes into contact with the aggregate 7 may be made of non-woven fabric, paper, or a resin layer. For example, as the tape member 8, a paper having a resin layer formed on one surface thereof may be used, and the resin layer having a smaller friction coefficient may be wound around the assembly 7 side.

テープ部材８は、その幅方向（テープ部材８の長手方向及び厚さ方向と垂直な方向）の一部が重なり合うように、螺旋状に集合体７に巻き付けられている。テープ部材８が重なり合う幅は、例えば、テープ部材８の幅の１／４以上１／２以下である。なお、本実施の形態において、テープ部材８が重なり合う部分は、接着剤等により接着されていない。 The tape member 8 is spirally wound around the assembly 7 so that the widthwise portions thereof (directions perpendicular to the longitudinal direction and the thickness direction of the tape member 8) overlap each other. The overlapping width of the tape members 8 is, for example, 1/4 or more and 1/2 or less of the width of the tape members 8. In the present embodiment, the overlapping portions of the tape members 8 are not adhered by an adhesive or the like.

テープ部材８の幅は、テープ部材８を巻き付けた際にテープ部材８に皺が寄らない程度の幅とすればよく、集合体７全体の外径が小さくなるほど幅の狭いテープ部材８を用いることが望ましい。具体的には、集合体７の外径が５ｍｍ〜９ｍｍである場合、テープ部材８の幅は、２０ｍｍ〜５０ｍｍ程度とすればよい。テープ部材８の巻きピッチＰ４、すなわちテープ部材８が周方向の同じ位置となる長手方向に沿った間隔（例えば幅方向の一端部同士の間隔）は、テープ部材８の幅及び重なり幅（テープ部材８の巻き付け角度）に依存し、この場合最大で４０ｍｍ程度となる。ここでは、テープ部材８の巻きピッチＰ４を約３０ｍｍとしたが、テープ部材８の巻きピッチＰ４はこれに限定されるものではない。 The width of the tape member 8 may be such that the tape member 8 does not become wrinkled when the tape member 8 is wound, and the tape member 8 having a smaller width is used as the outer diameter of the entire assembly 7 becomes smaller. Is desirable. Specifically, when the outer diameter of the aggregate 7 is 5 mm to 9 mm, the width of the tape member 8 may be about 20 mm to 50 mm. The winding pitch P4 of the tape member 8, that is, the interval along the longitudinal direction where the tape member 8 is at the same position in the circumferential direction (for example, the interval between the one ends in the width direction) is the width and the overlapping width of the tape member 8 (tape member). 8 winding angle), and in this case, the maximum is about 40 mm. Although the winding pitch P4 of the tape member 8 is about 30 mm here, the winding pitch P4 of the tape member 8 is not limited to this.

なお、テープ部材８の幅を大きくし、巻きピッチＰ４を大きくしていくと、テープ部材８を縦添えした状態に近くなり、複合ケーブル１の柔軟性が失われて曲げにくくなる。そのため、テープ部材８の巻きピッチＰ４は、４０ｍｍ以下とすることが望ましい。 When the width of the tape member 8 is increased and the winding pitch P4 is increased, the tape member 8 becomes closer to a vertically attached state, and the flexibility of the composite cable 1 is lost, and it becomes difficult to bend the composite cable 1. Therefore, it is desirable that the winding pitch P4 of the tape member 8 be 40 mm or less.

テープ部材８の周囲には、シース９が設けられる。シース９は、例えばウレタン樹脂からなる。本実施の形態では、第３電線６がＥＰＢ用電気モータ１０１ａに駆動電流を供給するものであり、第３電線６に駆動電流が流れる時間が比較的短いため、テープ部材８の周囲に設けられるシールド導体を省略しているが、第３電線６の用途等に応じて、テープ部材８とシース９との間、あるいはシース９の外周にシールド導体を設けてもよい。 A sheath 9 is provided around the tape member 8. The sheath 9 is made of urethane resin, for example. In the present embodiment, the third electric wire 6 supplies the drive current to the EPB electric motor 101a, and the time period during which the drive current flows through the third electric wire 6 is relatively short. Therefore, the third electric wire 6 is provided around the tape member 8. Although the shield conductor is omitted, a shield conductor may be provided between the tape member 8 and the sheath 9 or on the outer periphery of the sheath 9 depending on the application of the third electric wire 6 and the like.

（対撚線３，５と集合体７の撚り方向、テープ部材８の巻き付け方向）
本実施の形態に係る複合ケーブル１では、両対撚線３，５の撚り方向と集合体７の撚り方向とが同じ方向であり、集合体７の撚り方向とテープ部材８の巻き付け方向とが異なる方向となっている。 (Twisting direction of the twisted pair wires 3, 5 and the assembly 7, winding direction of the tape member 8)
In the composite cable 1 according to the present embodiment, the twisting directions of the paired twisted wires 3 and 5 are the same as the twisting direction of the assembly 7, and the twisting direction of the assembly 7 and the winding direction of the tape member 8 are the same. It's a different direction.

なお、ここでいう撚り方向とは、複合ケーブル１を先端側（図２（ｂ）の左側、テープ部材８の重なりが上となる側）から見たときに、電線２，４，６が基端側から先端側にかけて回転している方向をいう。ここでは、対撚線３，５の撚り方向、及び集合体７の撚り方向が右回り（時計回り）となる。なお、対撚線３，５の撚り方向とは、２本の電線２，４を撚り合わせる方向であり、集合体７の撚り方向とは、対撚線３，５と第３電線６とを撚り合わせる方向である。 The twisting direction here means that when the composite cable 1 is viewed from the tip side (the left side in FIG. 2B, the side where the tape member 8 is overlapped), the wires 2, 4, 6 are the bases. The direction of rotation from the end side to the tip side. Here, the twisting direction of the twisted pair wires 3 and 5 and the twisting direction of the assembly 7 are clockwise (clockwise). The twisting direction of the twisted pair wires 3 and 5 is the direction in which the two electric wires 2 and 4 are twisted together, and the twisting direction of the assembly 7 is the twisting direction of the twisted pair wires 3 and 5 and the third wire 6. It is the twisting direction.

また、テープ部材８の巻き付け方向とは、複合ケーブル１を先端側（図２（ｂ）の左側、テープ部材８の重なりが上となる側）から見た時に、テープ部材８が基端側から先端側にかけて回転している方向をいう。ここでは、テープ部材８の巻き付け方向は右回り（時計回り）となる。図２（ａ）では、先端側から見たときの断面図を示しており、第１対撚線３の撚り方向を破線矢印Ａ、第２対撚線５の撚り方向を破線矢印Ｂ、集合体７の撚り方向を破線矢印Ｃ、テープ部材８の巻き付け方向を破線矢印Ｄで表している。 Further, the winding direction of the tape member 8 means that the tape member 8 is from the base end side when the composite cable 1 is viewed from the tip end side (the left side in FIG. 2B, the side where the tape members 8 overlap each other). The direction of rotation toward the tip side. Here, the winding direction of the tape member 8 is clockwise (clockwise). FIG. 2A shows a cross-sectional view when viewed from the tip side, in which the twisting direction of the first twisted pair wire 3 is indicated by a broken arrow A, the twisting direction of the second twisted pair wire 5 is indicated by a broken arrow B, and The twisting direction of the body 7 is indicated by a broken arrow C, and the winding direction of the tape member 8 is indicated by a broken arrow D.

本実施の形態では、図２（ｂ）の側面視（先端側を左側、基端側を右側として複合ケーブル１を左右に直線状に配置した状態での側面視）においては、テープ部材８が左上がりとなるように巻回されており、かつ、集合体７を構成する対撚線３，５と第３電線６は左下がりとなるように撚り合わされている。つまり、図２（ｂ）の側面視においては、テープ部材８が傾斜している方向と、対撚線３，５や第３電線６（あるいは対撚線３，５と第３電線６間の溝）が傾斜している方向とが、逆方向となっている。また、対撚線３，５を構成する電線２，４は、図２（ｂ）の側面視においては、左下がりとなるように撚り合わされている。よって、図２（ｂ）の側面視においては、電線２，４（あるいは電線２，４間の溝）が傾斜している方向は、テープ部材８が傾斜している方向と逆方向となり、対撚線３，５や第３電線６（あるいは対撚線３，５と第３電線６間の溝）が傾斜している方向と同じ方向となっている。なお、ここでいう「傾斜している方向」とは、複合ケーブル１の長手方向（すなわち左右方向）に対して傾斜している方向である。 In the present embodiment, in a side view of FIG. 2B (side view in a state where the composite cable 1 is linearly arranged left and right with the front end side on the left side and the base end side on the right side), the tape member 8 is The pair of twisted wires 3 and 5 forming the assembly 7 and the third electric wire 6 are wound so as to rise to the left and twisted so as to descend to the left. That is, in the side view of FIG. 2B, the twisted direction of the tape member 8 and the twisted pair wires 3, 5 and the third electric wire 6 (or between the twisted pair wires 3, 5 and the third electric wire 6). The direction in which the grooves are inclined is the opposite direction. In addition, the electric wires 2 and 4 forming the twisted pair wires 3 and 5 are twisted so as to be downward leftward in the side view of FIG. 2B. Therefore, in the side view of FIG. 2B, the direction in which the electric wires 2 and 4 (or the groove between the electric wires 2 and 4) is inclined is opposite to the direction in which the tape member 8 is inclined, and The twisted wires 3 and 5 and the third electric wire 6 (or the groove between the twisted paired wires 3 and 5 and the third electric wire 6) are inclined in the same direction. The “inclined direction” mentioned here is a direction inclined with respect to the longitudinal direction (that is, the left-right direction) of the composite cable 1.

対撚線３，５の撚り方向と集合体７の撚り方向を同じ方向とすることにより、集合体７を撚り合わせる際に、２本の電線２，４を撚ることにより対撚線３，５に付与される曲がり癖に沿った方向に対撚線３，５と第３電線６を撚り合せることになる。このため、複合ケーブル１が屈曲する際に、対撚線３，５と第３電線６とが同調して複合ケーブル１の長手方向に伸縮するため、複合ケーブル１が曲がりやすくなり、複合ケーブル１の可撓性を向上させることが可能になる。 By setting the twisting direction of the twisted pair wires 3 and 5 to be the same as the twisting direction of the aggregate 7, when twisting the aggregate 7, the two wires 2 and 4 are twisted to twist the twisted pair wires 3, 4. The twisted pair wires 3, 5 and the third electric wire 6 are twisted together in the direction along the bending tendency given to the wire 5. Therefore, when the composite cable 1 bends, the twisted pair wires 3, 5 and the third electric wire 6 are synchronized with each other and expand and contract in the longitudinal direction of the composite cable 1, so that the composite cable 1 is easily bent and the composite cable 1 It is possible to improve the flexibility of the.

また、本実施の形態では、対撚線３，５の曲がり癖に沿った方向に撚り合せて集合体７を形成しているため、シース９を手作業でほどかずに、専用のストリップ装置等でシース９とテープ部材８とを同時に除去した場合に、対撚線３，５の曲がり癖の影響により、対撚線３，５と第３電線６とが撚られた状態のまま維持され易くなる。端末加工時にシース９の除去長を長くする場合には、複数回に分けてストリップ作業を行うが、複合ケーブル１では、１度ストリップ作業を行った後にも対撚線３，５と第３電線６とが撚られた状態で維持されるため、複数回のストリップ作業を容易に行うことが可能になる。 Further, in the present embodiment, since the assembly 7 is formed by twisting the twisted pair wires 3 and 5 in the direction along the bending habit, the sheath 9 is not manually unwound, and a dedicated strip device or the like is used. When the sheath 9 and the tape member 8 are removed at the same time, it is easy to maintain the twisted state of the twisted pair wires 3 and 5 and the third electric wire 6 due to the bending tendency of the twisted pair wires 3 and 5. Become. When the removal length of the sheath 9 is lengthened at the time of terminal processing, the stripping work is performed in plural times. However, in the composite cable 1, even after the stripping work is performed once, the twisted pair wires 3 and 5 and the third wire Since 6 and 6 are maintained in a twisted state, it is possible to easily perform a plurality of strip operations.

さらに、対撚線３，５の撚り方向と集合体７の撚り方向とを同じ方向とすることで、端末加工をする際に、集合体７の撚りをほぐすと対撚線３，５の撚りが自然にほぐれることになり、電線２，４，６をほぐし易くなる。これにより、複合ケーブル１の解体性が向上し、端末加工を行う際の作業性が向上する。 Furthermore, by twisting the twisted directions of the twisted pair wires 3 and 5 and the twisted direction of the aggregate 7 in the same direction, when twisting the aggregate 7 when the terminal processing is performed, the twisted pairs 3 and 5 are twisted. Will be naturally unraveled, and the electric wires 2, 4, 6 will be easily unraveled. As a result, disassemblability of the composite cable 1 is improved, and workability at the time of terminal processing is improved.

さらにまた、対撚線３，５の撚り方向と集合体７の撚り方向とを同じ方向とすることで、複合ケーブル１に捩れが加わった際に、対撚線３，５と集合体７とが同調して開いたり閉じたりすることになり、捩れに対する耐久性を向上させることが可能になる。 Furthermore, by making the twisting direction of the twisted pair wires 3 and 5 the same as the twisting direction of the assembly 7, when twisting is applied to the composite cable 1, the twisted pair wires 3 and 5 and the assembly 7 are separated from each other. Will open and close in synchronism with each other, and the durability against twisting can be improved.

これに関し、対撚線３，５の撚り方向と集合体７の撚り方向とを逆方向とした場合、例えば集合体７が開く（撚りがほぐれる）方向に複合ケーブル１に捩じれが加わった際には、対撚線３，５の撚りが締まり、捩れによるストレスが第１電線２と第２電線４に集中して、第１電線２や第２電線４の一部分に過大な負荷が加わってしまうおそれがある。また、集合体７が閉じる（撚りが締まる）方向に複合ケーブル１に捩じれが加わった際には、対撚線３，５の撚りがほぐれ、捩れによるストレスが第３電線６に集中して、第３電線６の一部分に過大な負荷が加わってしまうおそれがある。そのため、本実施の形態では、対撚線３，５の撚り方向と集合体７の撚り方向とを同じ方向とし、対撚線３，５と集合体７とが同調して開いたり閉じたりするようにしている。これにより、複合ケーブル１の捩じれに対する耐久性を向上させることが可能となる。 In this regard, when the twisting directions of the twisted pair wires 3 and 5 and the twisting direction of the assembly 7 are opposite to each other, for example, when twist is applied to the composite cable 1 in the direction in which the assembly 7 is opened (twisted). The twist of the twisted pair wires 3 and 5 is tightened, and the stress due to the twist is concentrated on the first electric wire 2 and the second electric wire 4, and an excessive load is applied to a part of the first electric wire 2 and the second electric wire 4. There is a risk. Further, when twist is applied to the composite cable 1 in the direction in which the assembly 7 is closed (twist is tightened), the twist of the twisted pair wires 3 and 5 is unraveled, and the stress due to the twist is concentrated on the third electric wire 6, An excessive load may be applied to a part of the third electric wire 6. Therefore, in the present embodiment, the twisting directions of the twisted pair wires 3 and 5 are the same as the twisting direction of the aggregate 7, and the twisted pair wires 3 and 5 and the aggregate 7 are opened and closed in synchronization. I am trying. As a result, the durability of the composite cable 1 against twisting can be improved.

なお、本実施の形態では、対撚線３，５の撚り方向と集合体７の撚り方向を同じ方向としているため、対撚線３，５の撚りピッチＰ１，Ｐ２と集合体７の撚りピッチＰ３が同じであると、第１電線２や第２電線４と第３電線６との位置関係が長手方向で常に同じとなり、複合ケーブル１の外観がいびつになってしまう可能性がある。そのため、対撚線３，５の撚りピッチＰ１，Ｐ２と集合体７の撚りピッチＰ３とを異ならせること（具体的には、対撚線３，５の撚りピッチＰ１，Ｐ２を、集合体７の撚りピッチＰ３よりも、集合体７の撚りピッチＰ３の１０％以上８０％以下小さくすること）が望ましい。対撚線３，５の撚りピッチＰ１，Ｐ２を集合体７の撚りピッチＰ３よりも大きくすると、集合体７を撚り合わせる際に対撚線３，５の撚りピッチＰ１，Ｐ２が変動してしまうおそれがあるため、対撚線３，５の撚りピッチＰ１，Ｐ２は、少なくとも集合体７の撚りピッチＰ３よりも小さいことが望ましい。 In the present embodiment, since the twisting directions of the twisted pair wires 3 and 5 and the twisting direction of the aggregate 7 are the same, the twisting pitches P1 and P2 of the twisted paired wires 3 and 5 and the twisting pitch of the aggregate 7 are the same. If P3 is the same, the positional relationship between the first electric wire 2, the second electric wire 4, and the third electric wire 6 is always the same in the longitudinal direction, and the appearance of the composite cable 1 may be distorted. Therefore, the twist pitches P1 and P2 of the twisted pair wires 3 and 5 and the twist pitch P3 of the aggregate 7 are made different (specifically, the twist pitches P1 and P2 of the twisted pair wires 3 and 5 are set to the aggregate 7 10% or more and 80% or less of the twist pitch P3 of the assembly 7 is preferable to the twist pitch P3 of No. If the twist pitches P1 and P2 of the twisted pair wires 3 and 5 are made larger than the twist pitch P3 of the aggregate 7, the twist pitches P1 and P2 of the twisted pair wires 3 and 5 change when the aggregate 7 is twisted together. Therefore, the twist pitches P1 and P2 of the twisted pair wires 3 and 5 are preferably at least smaller than the twist pitch P3 of the assembly 7.

集合体７の撚りピッチＰ３を小さくすると、複合ケーブル１を曲げやすくなり可撓性が向上するが、撚りに余裕がなくなり捩れに対する耐久性は低下してしまう。逆に、集合体７の撚りピッチＰ３を大きくすると、捩じれに対する耐久性は向上するが可撓性は低下する。本実施の形態では、捩れが加わった際に、対撚線３，５と集合体７とが同調して開いたり閉じたりして負荷を分散できるため、集合体７の撚りピッチＰ３を小さくして可撓性を向上させた場合であっても、捩れに対する耐久性を十分に確保することが可能である。 When the twisting pitch P3 of the assembly 7 is reduced, the composite cable 1 is easily bent and the flexibility is improved, but the twisting has no margin and the durability against twisting is reduced. On the contrary, if the twist pitch P3 of the aggregate 7 is increased, the durability against twisting is improved but the flexibility is decreased. In the present embodiment, when twist is applied, the twisted pair P3 of the assembly 7 can be reduced because the twisted pair 3, 5 and the assembly 7 can be opened and closed in synchronization with each other to distribute the load. Even when the flexibility is improved by the above method, it is possible to sufficiently secure the durability against twisting.

また、本実施の形態では、集合体７の撚り方向とテープ部材８の巻き付け方向とを異ならせているため、集合体７の曲がり癖とテープ部材８を巻き付けることによる曲がり癖とが逆方向となって互いに相殺されることになり、曲がり癖を抑制した直線状の複合ケーブル１を容易に実現できる。その結果、複合ケーブル１の長手方向における屈曲特性のばらつきを抑制することが可能になる。 Further, in the present embodiment, since the twisting direction of the assembly 7 and the winding direction of the tape member 8 are different, the curl habit of the assembly 7 and the curl habit caused by winding the tape member 8 are opposite to each other. As a result, the linear composite cables 1 in which the bending tendency is suppressed can be easily realized. As a result, it becomes possible to suppress variations in the bending characteristics of the composite cable 1 in the longitudinal direction.

本実施の形態では、テープ部材８を巻き付けることによる曲がり癖により、集合体７の曲がり癖を矯正しているため、テープ部材８の巻きピッチＰ４を、曲がり癖を付与できる程度に小さくする必要がある。そのため、テープ部材８の巻きピッチＰ４は、少なくとも集合体７の撚りピッチＰ３よりも小さくすることが望ましい。本実施の形態では、対撚線３，５の撚りピッチＰ１，Ｐ２を約３０ｍｍ、集合体７の撚りピッチＰ３を約６０ｍｍとしており、テープ部材８の巻きピッチＰ４を約３０ｍｍとしている。 In the present embodiment, since the curl habit of the assembly 7 is corrected by the curl habit caused by winding the tape member 8, it is necessary to make the winding pitch P4 of the tape member 8 small enough to impart the curl habit. is there. Therefore, it is desirable that the winding pitch P4 of the tape member 8 be smaller than at least the twist pitch P3 of the aggregate 7. In the present embodiment, the twist pitches P1 and P2 of the twisted pair wires 3 and 5 are about 30 mm, the twist pitch P3 of the assembly 7 is about 60 mm, and the winding pitch P4 of the tape member 8 is about 30 mm.

また、テープ部材８の巻きピッチＰ４は、対撚線３，５の撚りピッチＰ１，Ｐ２以上にすればよい。このようにすることで、対撚線３，５と接触している部分におけるテープ部材８の歪みを低減でき、複合ケーブル１の断面形状を円形状に成形しやくなる。 The winding pitch P4 of the tape member 8 may be set to be equal to or greater than the twist pitches P1 and P2 of the twisted pair wires 3 and 5. By doing so, the distortion of the tape member 8 in the portion in contact with the twisted pair wires 3 and 5 can be reduced, and the cross-sectional shape of the composite cable 1 can be easily formed into a circular shape.

なお、テープ部材８の巻きピッチＰ４が対撚線３，５の撚りピッチＰ１，Ｐ２より小さいと、複合ケーブル１を屈曲させた際に、巻きピッチＰ４が小さいテープ部材８は長手方向に伸縮して屈曲による負荷を受けにくくなり、撚りピッチＰ１，Ｐ２が大きく長手方向に伸縮しにくい対撚線３，５に屈曲による負荷が集中してしまう。テープ部材８の巻きピッチＰ４を、対撚線３，５の撚りピッチＰ１，Ｐ２以上とすることで、屈曲による負荷の一部をテープ部材８に負担させ、対撚線３，５に屈曲による負荷が集中してしまうことを抑制でき、屈曲耐久性を向上させることが可能になる。 If the winding pitch P4 of the tape member 8 is smaller than the twisting pitches P1 and P2 of the twisted pair wires 3 and 5, the tape member 8 having a small winding pitch P4 expands and contracts in the longitudinal direction when the composite cable 1 is bent. Therefore, the load due to bending is less likely to be received, and the load due to bending is concentrated on the twisted pair wires 3 and 5 in which the twist pitches P1 and P2 are large and it is difficult to expand and contract in the longitudinal direction. By setting the winding pitch P4 of the tape member 8 to be equal to or greater than the twist pitches P1 and P2 of the twisted pair wires 3 and 5, a part of the load due to bending is applied to the tape member 8 and the twisted pair wires 3 and 5 are bent. It is possible to prevent the load from being concentrated, and it is possible to improve the bending durability.

また、集合体７の撚り方向とテープ部材８の巻き付け方向とを異ならせることで、テープ部材８を巻き付ける際に、集合体７の撚りピッチＰ３が変化しにくくなり、集合体７の撚りピッチＰ３を安定させることが可能になる。 Further, by making the twist direction of the aggregate 7 different from the winding direction of the tape member 8, the twist pitch P3 of the aggregate 7 is less likely to change when the tape member 8 is wound, and the twist pitch P3 of the aggregate 7 is less likely to change. Can be stabilized.

さらに、集合体７の撚り方向とテープ部材８の巻き付け方向とを異ならせることで、テープ部材８が対撚線３，５と第３電線６との間の隙間に入り込んでしまうことが抑制され、テープ部材８の外周にシース９を押出被覆した際のテープ部材８の断面形状をより円形状に近くすることが可能になる。その結果、複合ケーブル１の外観を向上させると共に、シース９を除去するストリップ作業を容易に行うことが可能になる。本実施の形態に係る複合ケーブル１は、断面形状が円形状に近く、かつ、対撚線３，５の曲がり癖の影響により１度ストリップ作業を行った後にも対撚線３，５と第３電線６とが撚られた状態で維持されるため、複数回のストリップ作業をより容易に行うことが可能になる。 Furthermore, by making the twisting direction of the assembly 7 different from the winding direction of the tape member 8, it is possible to prevent the tape member 8 from entering the gap between the twisted pair wires 3, 5 and the third electric wire 6. The cross-sectional shape of the tape member 8 when the outer periphery of the tape member 8 is extrusion-coated with the sheath 9 can be made closer to a circular shape. As a result, the appearance of the composite cable 1 can be improved and the stripping operation for removing the sheath 9 can be easily performed. In the composite cable 1 according to the present embodiment, the cross-sectional shape is close to a circular shape, and even after the stripping work is performed once due to the influence of the bending tendency of the twisted pair wires 3, 5, the twisted pair wires 3, 5 Since the three electric wires 6 are maintained in a twisted state, it is possible to more easily perform the stripping operation a plurality of times.

さらにまた、集合体７の撚り方向とテープ部材８の巻き付け方向とを異ならせることで、集合体７が座屈し易い方向とテープ部材８が座屈し易い方向とを異ならせることができ、例えば複合ケーブル１に捩じれと曲げが同時に加わったような場合であっても、座屈しにくい複合ケーブル１を実現できる。 Furthermore, by making the twisting direction of the assembly 7 different from the winding direction of the tape member 8, the direction in which the assembly 7 is likely to buckle and the direction in which the tape member 8 is likely to buckle can be made different. Even if the cable 1 is twisted and bent at the same time, it is possible to realize the composite cable 1 that is less likely to buckle.

（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複合ケーブル１では、集合体７の周囲に螺旋状に巻き付けられているテープ部材８を備え、両対撚線３，５の撚り方向と集合体７の撚り方向とが同じ方向であり、集合体７の撚り方向とテープ部材８の巻き付け方向とが異なっている。 (Operation and Effect of Embodiment)
As described above, the composite cable 1 according to the present embodiment is provided with the tape member 8 that is spirally wound around the assembly 7, and the twist direction of the paired twisted wires 3 and 5 and the assembly 7 are arranged. And the winding direction of the tape member 8 are different from each other.

テープ部材８を備えることで、タルク粉体等の潤滑剤を用いずとも、電線２，４，６とシース９間の摩擦を低減し、屈曲時に電線２，４，６にかかるストレスを低減して、耐屈曲性を向上させることが可能になる。つまり、本実施の形態によれば、屈曲耐久性を維持しつつも端末加工の作業環境の悪化を抑制することが可能になる。 By providing the tape member 8, the friction between the electric wires 2, 4, 6 and the sheath 9 can be reduced and the stress applied to the electric wires 2, 4, 6 at the time of bending can be reduced without using a lubricant such as talc powder. Thus, it becomes possible to improve the bending resistance. That is, according to the present embodiment, it is possible to suppress deterioration of the working environment for terminal processing while maintaining bending durability.

また、両対撚線３，５の撚り方向と集合体７の撚り方向とを同じ方向とし、かつ、集合体７の撚り方向とテープ部材８の巻き付け方向とを異ならせることで、捩れに対する耐久性を向上させつつも、集合体７の周囲のテープ部材８の断面形状をより円形状に近くしてシース９のストリップ作業を容易に行うことが可能になり、捩れに対する耐久性と端末加工の作業性を共に向上することができる。 Further, by making the twisting direction of both twisted pair wires 3 and 5 the same as the twisting direction of the aggregate 7, and making the twisting direction of the aggregate 7 different from the winding direction of the tape member 8, durability against twisting is obtained. It is possible to easily perform the stripping operation of the sheath 9 by making the cross-sectional shape of the tape member 8 around the assembly 7 closer to a circular shape while improving the durability, and to improve the durability against twisting and the end processing. Workability can be improved together.

さらに、対撚線３，５の撚り方向と集合体７の撚り方向とを同じ方向とすることで可撓性を向上でき、かつ、集合体７の撚り方向とテープ部材８の巻き付け方向とを異なる方向とすることで曲がり癖を矯正できるので、曲げやすく長手方向における屈曲特性のばらつきも少ない配策性の良好な複合ケーブル１を実現できる。 Further, by making the twisting directions of the twisted pair wires 3 and 5 and the twisting direction of the assembly 7 the same, flexibility can be improved, and the twisting direction of the assembly 7 and the winding direction of the tape member 8 can be changed. Since the bending tendency can be corrected by making the directions different, it is possible to realize the composite cable 1 which is easy to bend and has little variation in bending characteristics in the longitudinal direction and has good routing performance.
