When grasped in the relationship between the communication cable 20 and the wiring member 30, the wiring member 30 is a wiring member that becomes a noise source with respect to the signal line 21 included in the communication cable 20, and the signal line 21 included in the communication cable 20. Is a wiring member affected by noise from the wiring member 30. Since the signal line 21 and the wiring member 30 are held at a distance by the sheath 26 of the communication cable 20, the influence of noise from the wiring member 30 to the signal line 21 is reduced. Note that the communication cable 20 and the wiring member 30 may be branched at the end portion of the wire harness 10 and guided to different wiring destinations. The end portions of the communication cable 20 and the wiring member are connected to various electric components mounted on the vehicle or the like via a connector or the like. That is, the wire harness 10 is used as wiring for electrically connecting various electrical components and the like in the vehicle.
　通信ケーブル２０は、車両等において、電気機器間の通信配線として用いられるケーブルであり、撚り合わされた複数の信号線２１と、複数の信号線２１を覆うシース２６とを備える。 The communication cable 20 is a cable used as a communication wiring between electrical devices in a vehicle or the like, and includes a plurality of twisted signal lines 21 and a sheath 26 that covers the plurality of signal lines 21.
　信号線２１は、銅、銅合金、アルミニウム、アルミニウム合金等の導電性線材で形成された芯線２２と、芯線２２の周囲を覆う被覆２３とを備える。芯線２２は、金属線が撚り合わされたものであってもよいし、単一の金属線によって構成されていてもよい。被覆２３は、芯線２２の周囲に軟化した樹脂を押出被覆等することによって形成されている。ここでは、通信ケーブル２０は、２つの信号線２１を備えており、２つの信号線２１が撚り合わされたツイストペアケーブルとされている。通信ケーブルは、３つ以上の信号線を備えていてもよい。 The signal line 21 includes a core wire 22 formed of a conductive wire material such as copper, copper alloy, aluminum, and aluminum alloy, and a coating 23 that covers the periphery of the core wire 22. The core wire 22 may be formed by twisting metal wires, or may be constituted by a single metal wire. The coating 23 is formed by extrusion-coating a softened resin around the core wire 22. Here, the communication cable 20 includes two signal lines 21 and is a twisted pair cable in which the two signal lines 21 are twisted together. The communication cable may include three or more signal lines.
　シース２６は、撚り合わされた複数の信号線２１の外周を覆う絶縁性部材である。シース２６は、撚り合わされた複数の信号線２１の周囲に軟化した樹脂を押出被覆すること等によって形成されている。つまり、シース２６は、複数の信号線２１の周囲を覆うチューブ状に形成され、かつ、そのチューブをなす被覆部分では樹脂が埋った形態とされている。 The sheath 26 is an insulating member that covers the outer periphery of the plurality of signal wires 21 twisted together. The sheath 26 is formed by extrusion-coating a softened resin around the plurality of signal lines 21 twisted together. That is, the sheath 26 is formed in a tube shape that covers the periphery of the plurality of signal lines 21, and the covering portion that forms the tube is filled with resin.
　シース２６の横断面（通信ケーブル２０の延在方向に対して直交する面における断面）の外周形状は、非円形形状を呈している。より具体的には、シース２６は、シース本体部２７と、突出部２８とを備える。 The outer peripheral shape of the cross section of the sheath 26 (the cross section in the plane orthogonal to the extending direction of the communication cable 20) is a non-circular shape. More specifically, the sheath 26 includes a sheath main body 27 and a protrusion 28.
　シース本体部２７は、複数の信号線２１の周囲を覆うように、横断面円形状をなすチューブ状に形成されている。すなわち、シース本体部２７の横断面の内周部は円形状をなし、シース本体部２７の横断面の外周部もその内周部の径よりも大きい円形状をなしている。従って、シース本体部２７の厚み寸法は、その周方向において一定となっている。もっとも、シース本体部２７の内周部は、撚り合わされた複数の信号線２１の間に充填されていてもよい。 The sheath body 27 is formed in a tube shape having a circular cross section so as to cover the periphery of the plurality of signal lines 21. That is, the inner peripheral part of the cross section of the sheath main body 27 has a circular shape, and the outer peripheral part of the cross section of the sheath main body 27 has a circular shape larger than the diameter of the inner peripheral part. Therefore, the thickness dimension of the sheath body 27 is constant in the circumferential direction. But the inner peripheral part of the sheath main-body part 27 may be filled between the several signal wires 21 twisted together.
　突出部２８は、シース本体部２７の外周部の一部から突出する形状に形成されている。ここでは、突出部２８は、基部２８ａと、幅広突部２８ｂとを備える。基部２８ａは、シース本体部２７の外周部からその径方向外側に向けて突出する形状に形成されている。基部２８ａは、通信ケーブル２０の延在方向全体に亘って延在する長尺状に形成されていることが好ましいが、これは必須ではない。幅広突部２８ｂは、基部２８ａの先端部の幅を広げる方向に突出している。ここでは、幅広突部２８ｂは、基部２８ａの先端部からその両側に突出する形状に形成されている。このため、突出部２８を、通信ケーブル２０の横断面において観察すると、Ｔ字状をなしている。幅広突部は、基部の先端部から一側部のみに突出していてもよい。また、幅広突部２８ｂは、省略されてもよい。突出部は、シース本体部から突出する形状であればよく、その形状は任意である。 The protruding portion 28 is formed in a shape protruding from a part of the outer peripheral portion of the sheath body portion 27. Here, the protrusion part 28 is provided with the base part 28a and the wide protrusion part 28b. The base portion 28a is formed in a shape that protrudes from the outer peripheral portion of the sheath main body portion 27 toward the radially outer side. The base 28a is preferably formed in a long shape extending in the entire extending direction of the communication cable 20, but this is not essential. The wide protrusion 28b protrudes in the direction of increasing the width of the tip of the base 28a. Here, the wide protrusion 28b is formed in a shape protruding from both ends of the base 28a. For this reason, when the protrusion part 28 is observed in the cross section of the communication cable 20, it has comprised T shape. The wide protrusion may protrude from the tip of the base only to one side. Further, the wide protrusion 28b may be omitted. The protruding portion may be any shape that protrudes from the sheath body, and the shape is arbitrary.
　上記通信ケーブル２０としては、車内ＬＡＮ通信用のケーブルであること、特に、イーサネット（登録商標）規格に準拠する高速通信用のケーブルであること等が想定される。 The communication cable 20 is assumed to be a cable for in-vehicle LAN communication, in particular, a cable for high-speed communication complying with the Ethernet (registered trademark) standard.
　配線部材３０は、車両等において、電気部品等に接続される配線用の部材であり、ここでは、少なくとも１本の電線３１を含む配線部材である。本実施形態においては、配線部材３０は、複数の電線３１が束ねられている例で説明する。本配線部材３０の少なくとも一部は、上記通信ケーブル２０に対して並列して配設される。 The wiring member 30 is a wiring member connected to an electrical component or the like in a vehicle or the like, and here is a wiring member including at least one electric wire 31. In the present embodiment, the wiring member 30 will be described as an example in which a plurality of electric wires 31 are bundled. At least a part of the wiring member 30 is arranged in parallel with the communication cable 20.
　上記配線部材３０として、電源線を含む例が挙げられる。この場合、配線部材３０は、通信ケーブル２０に対してノイズの影響を与え易い。もっとも、配線部材３０は、その他の通信用の信号線、センサ用の信号線等を含んでいてもよい。 Examples of the wiring member 30 include a power supply line. In this case, the wiring member 30 tends to affect the communication cable 20 with noise. However, the wiring member 30 may include other signal lines for communication, signal lines for sensors, and the like.
　上記通信ケーブル２０と配線部材３０とは、シース２６のうち外側に出ている部分である突出部２８を配線部材３０側に配設した状態で、並列状態に配設されている。ここでは、突出部２８の幅広突部２８ｂの外向き部分に配線部材３０の外周の一部を接触させた状態で、通信ケーブル２０と配線部材３０とが粘着テープ、結束バンド、保護シート等の結束部材４０によって結束されている。このため、通信ケーブル２０と配線部材３０とは、結束部材４０によって並列状態に束ねられている。また、この状態で、通信ケーブル２０に含まれる信号線２１と、配線部材３０との間に、突出部２８の突出寸法以上の間隔が隔てられた状態となっている。 The communication cable 20 and the wiring member 30 are arranged in a parallel state with the protruding portion 28, which is a portion protruding outside the sheath 26, arranged on the wiring member 30 side. Here, the communication cable 20 and the wiring member 30 are made of an adhesive tape, a binding band, a protective sheet, etc. in a state where a part of the outer periphery of the wiring member 30 is in contact with the outward portion of the wide protrusion 28b of the protrusion 28. They are bound by the binding member 40. For this reason, the communication cable 20 and the wiring member 30 are bundled in a parallel state by the binding member 40. Further, in this state, the signal line 21 included in the communication cable 20 and the wiring member 30 are spaced apart by a distance equal to or larger than the protruding dimension of the protruding portion 28.
　上記通信ケーブル２０を製造する方法の一例について説明する。図４及び図５は、上記通信ケーブル２０を製造するための押出被覆装置５０を示す概略図である。 An example of a method for manufacturing the communication cable 20 will be described. 4 and 5 are schematic views showing an extrusion coating apparatus 50 for manufacturing the communication cable 20.
　押出被覆装置５０は、樹脂供給部５２と、押出ヘッド６０とを備える。 The extrusion coating apparatus 50 includes a resin supply unit 52 and an extrusion head 60.
　樹脂供給部５２は、押出ヘッド６０に対して加熱軟化して流動状態となった樹脂材料を供給する部分である。この樹脂供給部５２は、シース２６を形成するための樹脂材料を加熱して軟化させて流動状態とし、この流動状態となった樹脂材料をスクリューにより押出ヘッドに向けて送る構成等を採用することができる。ここでは、樹脂供給部５２は、押出ヘッド６０に対して上下２箇所から流動状態となった樹脂材料を供給する（図４は一方のみ図示）。 The resin supply unit 52 is a part that supplies the resin material that has been softened by heating to the extrusion head 60 and is in a fluid state. The resin supply unit 52 employs a configuration in which the resin material for forming the sheath 26 is heated and softened to be in a fluidized state, and the fluidized resin material is sent to the extrusion head by a screw. Can do. Here, the resin supply part 52 supplies the resin material that has flowed to the extrusion head 60 from two upper and lower positions (FIG. 4 shows only one of them).
　押出ヘッド６０は、内側ダイ６２と、外側ダイ６４とを備える。 The extrusion head 60 includes an inner die 62 and an outer die 64.
　内側ダイ６２は、撚り合わされた複数の信号線２１を通過させてガイド可能に構成されている。すなわち、内側ダイ６２には、撚り合せ体を通過可能なガイド孔６３が形成されている。 The inner die 62 is configured to be able to guide through a plurality of twisted signal lines 21. That is, the inner die 62 has a guide hole 63 that can pass through the twisted body.
　内側ダイ６２の先端側部分は、先端部に向けて徐々に小径となる円錐状に形成されている。上記ガイド孔６３の中心軸は、内側ダイ６２の円錐状部分の中心と一致している。従って、ガイド孔６３は、内側ダイ６２の先端側部分の頂点に対応する位置で開口している。 The tip side portion of the inner die 62 is formed in a conical shape that gradually decreases in diameter toward the tip. The central axis of the guide hole 63 coincides with the center of the conical portion of the inner die 62. Therefore, the guide hole 63 is opened at a position corresponding to the apex of the tip side portion of the inner die 62.
　外側ダイ６４内には、円錐状の空間が形成されている。この外側ダイ６４の円錐状の空間を囲む周面と、内側ダイ６２の円錐状の外周面との間には、円錐周面状の流路６６が形成されている。 A conical space is formed in the outer die 64. Between the peripheral surface surrounding the conical space of the outer die 64 and the conical outer peripheral surface of the inner die 62, a conical peripheral surface channel 66 is formed.
　上記流路６６のうち幅広となる基端部には、樹脂供給部５２からの樹脂材料を当該流路６６に向けて導くための導入路６７が形成されている。 An introduction path 67 for guiding the resin material from the resin supply section 52 toward the flow path 66 is formed at the base end portion which is wide in the flow path 66.
　また、外側ダイ６４の先端部であって、ガイド孔６３の延長上には、吐出口６８が形成されている。吐出口６８を、ガイド孔６３の軸方向に沿って外側から視ると、円形状部分の外周の一部にＴ字状開口部分が連なる開口形状に形成されている。この吐出口６８の開口形状が、シース２６の外形状を規定する。 Also, a discharge port 68 is formed at the tip of the outer die 64 and on the extension of the guide hole 63. When the discharge port 68 is viewed from the outside along the axial direction of the guide hole 63, the discharge port 68 is formed in an opening shape in which a T-shaped opening portion is continuous with a part of the outer periphery of the circular portion. The opening shape of the discharge port 68 defines the outer shape of the sheath 26.
　そして、撚り合わされた複数の信号線２１を、上記ガイド孔６３及び吐出口６８を通るように連続的に送る（工程（ａ））。この際、撚り合わされた複数の信号線の外周に、流路６６を通って供給される軟化した樹脂を、押出被覆する。すると、横断面の外周形状が上記のように非円形形状を呈するシース２６が形成される（工程（ｂ））。 Then, the plurality of twisted signal lines 21 are continuously sent so as to pass through the guide hole 63 and the discharge port 68 (step (a)). At this time, the softened resin supplied through the channel 66 is extrusion coated on the outer periphery of the twisted signal lines. As a result, the sheath 26 having a non-circular shape as described above is formed (step (b)).
　以上のように構成された通信ケーブル２０、ワイヤーハーネス１０及び通信ケーブル２０の製造方法によると、シース２６の横断面の外周形状が非円形断面を呈するため、シース２６のうち外側に出ている部分を他の配線部材３０側に配設することによって、通信ケーブル２０に含まれる複数の信号線２１を、当該他の配線部材３０に対して間隔をあけて配設できる。具体的には、シース本体部２７の外周部の一部から突出する突出部２８を、他の配線部材３０側に配設することによって、通信ケーブル２０に含まれる複数の信号線２１を、当該他の配線部材３０に対して間隔をあけて配設できる。しかも、シースの全体を厚く形成しなくてもよいため、全体として軽量化が可能となる。 According to the manufacturing method of the communication cable 20, the wire harness 10, and the communication cable 20 configured as described above, the outer peripheral portion of the sheath 26 has a non-circular cross section, and therefore the portion of the sheath 26 that protrudes to the outside. By disposing on the other wiring member 30 side, a plurality of signal lines 21 included in the communication cable 20 can be disposed with a space from the other wiring member 30. Specifically, by arranging the protruding portion 28 protruding from a part of the outer peripheral portion of the sheath body portion 27 on the other wiring member 30 side, the plurality of signal lines 21 included in the communication cable 20 are The wiring members 30 can be arranged at intervals with respect to the other wiring members 30. In addition, since the entire sheath does not have to be formed thick, the overall weight can be reduced.
　しかも、突出部２８は、基部２８ａとその基部２８ａの先端部を幅広にする幅広突部２８ｂとを有し、当該幅広突部２８ｂを配線部材３０に接触させた状態とすることができる。幅広突部２８ｂによって、配線部材３０が安定して接触した状態となるため、通信ケーブル２０に含まれる複数の信号線２１を、当該他の配線部材３０に対して安定して離した状態とすることができる。 Moreover, the protruding portion 28 has a base portion 28 a and a wide protrusion portion 28 b that widens the tip end portion of the base portion 28 a, and the wide protrusion portion 28 b can be brought into contact with the wiring member 30. Since the wiring member 30 is in stable contact with the wide protrusion 28b, the plurality of signal lines 21 included in the communication cable 20 are stably separated from the other wiring member 30. be able to.
　なお、通信ケーブルと配線部材との間で電磁ノイズの影響を抑制する方法としては、外周に金属製の編組等が形成されたシールド電線を用いることが想定される。しかしながら、そのようなシールド電線を用いると高コストとなる。これに対して、ワイヤーハーネス１０では、通信ケーブル２０と配線部材３０との間に空間的距離を設けることで、ノイズの影響を抑制している。これにより、コストアップを抑制しつつ、通信ケーブル２０と配線部材３０との間のノイズの影響を低減することができる。もちろん、通信ケーブル２０及び配線部材３０を構成する電線として、シールド電線が採用されたり、それらの間にシールド層が設けられたりしてもよい。 As a method for suppressing the influence of electromagnetic noise between the communication cable and the wiring member, it is assumed that a shielded electric wire having a metal braid or the like formed on the outer periphery is used. However, the use of such a shielded wire is expensive. On the other hand, in the wire harness 10, the influence of noise is suppressed by providing a spatial distance between the communication cable 20 and the wiring member 30. Thereby, the influence of the noise between the communication cable 20 and the wiring member 30 can be reduced, suppressing a cost increase. Of course, shielded wires may be adopted as the wires constituting the communication cable 20 and the wiring member 30, or a shield layer may be provided between them.
　｛変形例｝
　図６は変形例に係るワイヤーハーネス１１０を示す概略断面図である。本ワイヤーハーネス１１０が、上記ワイヤーハーネス１０と異なるのは、通信ケーブル２０に代えて、通信ケーブル１２０を備えている点である。 {Modification}
FIG. 6 is a schematic cross-sectional view showing a wire harness 110 according to a modification. The wire harness 110 is different from the wire harness 10 in that a communication cable 120 is provided instead of the communication cable 20.
　通信ケーブル１２０は、上記と同様に、撚り合わされた複数の信号線２１と、この外周を覆うシース１２６とを備える。 The communication cable 120 includes a plurality of twisted signal lines 21 and a sheath 126 that covers the outer periphery in the same manner as described above.
　シース１２６は、シース本体部１２７と、シース本体部１２７の外周部の複数箇所のそれぞれに設けられた複数の突出部１２８とを備える。ここでは、シース１２６の横断面形状の外周部において、複数箇所に突出部１２８が設けられている。ここでは、複数の突出部１２８は、シース１２６の外周部に均等間隔で設けられている。つまり、複数の突出部１２８は、シース本体部１２８から放射状に外部に突出している。隣合う突出部１２８の間に配線部材３０が入り込まないように、隣合う突出部１２８の間隔寸法は、配線部材３０の外径よりも小さい寸法であることが好ましい。もっとも、複数の突出部は、シースの外周部に均等間隔で設けられていなくてもよい。 The sheath 126 includes a sheath body 127 and a plurality of protrusions 128 provided at each of a plurality of locations on the outer periphery of the sheath body 127. Here, protrusions 128 are provided at a plurality of locations on the outer peripheral portion of the cross-sectional shape of the sheath 126. Here, the plurality of protrusions 128 are provided at equal intervals on the outer periphery of the sheath 126. That is, the plurality of projecting portions 128 project radially outward from the sheath main body portion 128. It is preferable that the distance between adjacent protrusions 128 is smaller than the outer diameter of the wiring member 30 so that the wiring member 30 does not enter between the adjacent protrusions 128. But the some protrusion part does not need to be provided in the outer peripheral part of the sheath at equal intervals.
　また、ここでは、突出部１２８は、通信ケーブル１２０の径方向に沿って延在し、かつ、その厚み寸法が基端部から先端部に向ってほぼ同一である細長板状をなす形状に形成されている。もっとも、突出部は、上記実施形態と同様に、横断面Ｔ字状等の形状をなしていてもよい。 Further, here, the protruding portion 128 is formed in an elongated plate shape that extends along the radial direction of the communication cable 120 and whose thickness dimension is substantially the same from the proximal end portion toward the distal end portion. Has been. But the protrusion part may comprise shapes, such as a cross-sectional T shape, similarly to the said embodiment.
　そして、上記実施形態と同様に、通信ケーブル１２０と配線部材３０とを並列状態となるように結束部材４０で結束すると、配線部材３０が突出部１２８の少なくとも１つ（ここでは、隣合う２つ）に先端部に接する。これにより、通信ケーブル２０に含まれる信号線２１と配線部材３０との間に、突出部１２８の突出寸法程度の隙間が設けられる。このため、上記実施形態と同様に、通信ケーブル２０に含まれる信号線２１と配線部材３０とを離して配設することができる。 As in the above embodiment, when the communication cable 120 and the wiring member 30 are bound by the binding member 40 so as to be in a parallel state, the wiring member 30 has at least one of the protrusions 128 (here, two adjacent ones). ) In contact with the tip. As a result, a gap having a protruding dimension of the protruding portion 128 is provided between the signal line 21 and the wiring member 30 included in the communication cable 20. For this reason, similarly to the above-described embodiment, the signal line 21 and the wiring member 30 included in the communication cable 20 can be arranged apart from each other.
　また、通信ケーブル１２０の周囲に複数の突出部１２８が設けられているため、通信ケーブル１２０の回転方向の向きを一定にしなくても、また、途中でねじれ等が生じていても、通信ケーブル２０に含まれる信号線２１と配線部材３０とを離して配設することができる。 In addition, since the plurality of projecting portions 128 are provided around the communication cable 120, the communication cable 20 can be used even if the rotation direction of the communication cable 120 is not constant or twisted in the middle. The signal line 21 and the wiring member 30 included in the circuit board can be separated from each other.
　以上のようにこの発明は詳細に説明されたが、上記した説明は、すべての局面において、例示であって、この発明がそれに限定されるものではない。例示されていない無数の変形例が、この発明の範囲から外れることなく想定され得るものと解される。 Although the present invention has been described in detail as described above, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
