以下、実施形態に係るワイヤーハーネスについて説明する。図１は、実施形態に係るワイヤーハーネス１０を示す正面図である。 {Embodiment}
Hereinafter, the wire harness which concerns on embodiment is demonstrated. Drawing 1 is a front view showing
ワイヤーハーネス１０は、第１配線部材１２と、第１配線部材１２と並行する第２配線部材１４と、外装部材２０と、を備える。ワイヤーハーネス１０において、第１配線部材１２と第２配線部材１４とは離して配設されている。これにより、第１配線部材１２と第２配線部材１４との間のノイズの影響を低減可能となっている。
The wire harness 10 includes a first wiring member 12, a second wiring member 14 parallel to the first wiring member 12, and an exterior member 20. In the wire harness 10, the first wiring member 12 and the second wiring member 14 are disposed apart from each other. Thereby, the influence of the noise between the 1st wiring member 12 and the 2nd wiring member 14 can be reduced.
各配線部材１２、１４は少なくとも１本の電線１１を含む。ここでは、第１配線部材１２は、複数の電線１１の束で構成されているものとして説明する。またここでは、第２配線部材１４は、２本の電線１１が撚り合わされた、いわゆるツイスト電線１５を含み、当該ツイスト電線１５の周囲にシース１６が設けられた構成であるものとして説明する。そして、本ワイヤーハーネス１０が車両に組込まれた状態で、各配線部材１２、１４は、電線１１の端部に設けられたコネクタ等を介して車両に搭載された各種電気部品に接続される。これにより、ワイヤーハーネス１０は、車両に搭載された各種電気部品を電気的に接続する役割を果す。ワイヤーハーネス１０に含まれる電線１１は、車両における敷設経路に応じた形態で結束される。
Each wiring member 12, 14 includes at least one electric wire 11. Here, the 1st wiring member 12 is demonstrated as what is comprised by the bundle | flux of the some electric wire 11. FIG. In addition, here, the second wiring member 14 will be described as including a so-called twisted electric wire 15 in which two electric wires 11 are twisted together, and a sheath 16 provided around the twisted electric wire 15. Then, in a state where the wire harness 10 is incorporated in the vehicle, the wiring members 12 and 14 are connected to various electrical components mounted on the vehicle via connectors or the like provided at the ends of the electric wires 11. Thereby, the wire harness 10 plays the role which electrically connects the various electrical components mounted in the vehicle. The electric wires 11 included in the wire harness 10 are bundled in a form corresponding to the laying route in the vehicle.
ここでは、第１配線部材１２がノイズ源となりやすい部材であり、第２配線部材１４が第１配線部材１２からのノイズの影響を受けやすい部材であるものとして説明する。このような配線部材１２、１４の組み合わせとしては、例えば、第１配線部材１２が電源線であり、第２配線部材１４が信号線であるものが挙げられる。ここでは、第１配線部材１２が電源線であり、第２配線部材１４が、車内ＬＡＮ通信用のケーブルであり、特にここでは、第２配線部材１４がイーサネット（登録商標）規格に準拠する高速通信用のケーブルであるものとして説明する。第１配線部材１２と第２配線部材１４とは、当該ノイズの影響を低減させるために離して配設されている。
Here, the first wiring member 12 is a member that is likely to be a noise source, and the second wiring member 14 is a member that is easily affected by noise from the first wiring member 12. Examples of such a combination of the wiring members 12 and 14 include one in which the first wiring member 12 is a power supply line and the second wiring member 14 is a signal line. Here, the first wiring member 12 is a power supply line, the second wiring member 14 is a cable for in-vehicle LAN communication, and particularly here, the second wiring member 14 is a high-speed conforming to the Ethernet (registered trademark) standard. The description will be made assuming that the cable is for communication. The first wiring member 12 and the second wiring member 14 are spaced apart to reduce the influence of the noise.
ここで、配線部材１２、１４においてノイズの影響を低減させる方法として、配線部材１２、１４を構成する電線１１として絶縁電線の周囲にシールド層と外皮とが形成されたシールド電線を用いること、及びノイズ源から遠ざけることなどが挙げられる。しかしながら、配線部材を構成する電線１１としてシールド電線を用いると、ワイヤーハーネス１０のコストが上昇する恐れがあると共にシールド層を接地する必要が生じる。そこでここでは、配線部材１２、１４を構成する電線１１としてシールド電線でない電線を採用する代わりに各配線部材１２、１４同士を離して配線することで、コスト上昇を抑えつつ各配線部材１２、１４間のノイズの影響を低減させるものである。もちろん、配線部材１２、１４を構成する電線１１としてシールド電線が採用されてもよい。
Here, as a method of reducing the influence of noise in the wiring members 12 and 14, using a shielded wire in which a shield layer and an outer skin are formed around the insulated wire as the wire 11 constituting the wiring members 12 and 14, and For example, keep away from noise sources. However, if a shielded wire is used as the wire 11 constituting the wiring member, the cost of the wire harness 10 may increase and the shield layer needs to be grounded. Therefore, here, the wiring members 12 and 14 are separated from each other instead of using the non-shielded wires as the wires 11 constituting the wiring members 12 and 14, so that the wiring members 12 and 14 are suppressed while increasing costs. It is intended to reduce the influence of noise between. Of course, a shielded electric wire may be adopted as the electric wire 11 constituting the wiring members 12 and 14.
外装部材２０は、第１配線部材１２と第２配線部材１４との周囲を覆っている。また、外装部材２０は、第１配線部材１２と第２配線部材１４とを離す役割を担っている。ここでは、外装部材２０は、曲げ変形可能なシート状部材２１（図３参照）を材料として形成されている。かかるシート状部材２１としては、例えば、ＰＰ（ポリプロピレン）シート、ＰＶＣ（ポリ塩化ビニル）シート又はＰＥＴ（ポリエチレンテレフタレート）シート等の樹脂製の内部が一様に埋まっている中実シート材、プラスチックダンボール等の中空板材、発泡シート又は不織布等を用いることができる。かかるシート状部材２１としては、後述する中間部２６が第１配線部材１２と第２配線部材１４とを離した状態を保てる程度の剛性を有していることが考えられる。もっとも、シート状部材２１の剛性は上記したものより低くてもよい。この場合、中間部２６の剛性が部分的に高められていることが好ましい。例えば、不織布を材料として外装部材２０を形成する場合、中間部２６を構成する部分を加熱プレスすることによって、当該部分が他の部分よりも剛性が高められる。具体的には、外装部材２０は、第１端部２２と、第２端部２４と、中間部２６とを含む。
The exterior member 20 covers the periphery of the first wiring member 12 and the second wiring member 14. The exterior member 20 plays a role of separating the first wiring member 12 and the second wiring member 14. Here, the exterior member 20 is formed using a sheet-like member 21 (see FIG. 3) that can be bent and deformed. Examples of the sheet-like member 21 include a solid sheet material in which a resin interior such as a PP (polypropylene) sheet, a PVC (polyvinyl chloride) sheet, or a PET (polyethylene terephthalate) sheet is uniformly embedded, and plastic cardboard. A hollow plate material such as a foamed sheet or a nonwoven fabric can be used. As such a sheet-like member 21, it is conceivable that an intermediate portion 26, which will be described later, has rigidity enough to keep the first wiring member 12 and the second wiring member 14 apart. However, the rigidity of the sheet-like member 21 may be lower than that described above. In this case, it is preferable that the rigidity of the intermediate portion 26 is partially increased. For example, when forming the exterior member 20 using a nonwoven fabric as a material, the portion of the intermediate portion 26 is heated and pressed, so that the rigidity of the portion is higher than that of other portions. Specifically, the exterior member 20 includes a first end portion 22, a second end portion 24, and an intermediate portion 26.
第１端部２２は、シート状部材２１の一端部である。第１端部２２は、第１配線部材１２を覆っている。ここでは、第１端部２２は第１配線部材１２に巻付けられている。第１端部２２の先端２３は、中間部２６に重ねられて、中間部２６に溶着されている。
The first end 22 is one end of the sheet-like member 21. The first end portion 22 covers the first wiring member 12. Here, the first end portion 22 is wound around the first wiring member 12. The distal end 23 of the first end portion 22 is overlapped with the intermediate portion 26 and welded to the intermediate portion 26.
第２端部２４は、シート状部材２１の他端部であり、第１端部２２とは反対側の端部である。第２端部２４は、第２配線部材１４を覆っている。ここでは、第２端部２４は第２配線部材１４に巻付けられている。第２端部２４の先端２５は、中間部２６に重ねられて、中間部２６に溶着されている。
The second end 24 is the other end of the sheet-like member 21 and is the end opposite to the first end 22. The second end portion 24 covers the second wiring member 14. Here, the second end portion 24 is wound around the second wiring member 14. The distal end 25 of the second end portion 24 is overlapped with the intermediate portion 26 and welded to the intermediate portion 26.
中間部２６は、第１端部２２と第２端部２４との間の部分である。中間部２６は、第１配線部材１２と第２配線部材１４との間で両者が並ぶ方向に延在して第１配線部材１２と第２配線部材１４とを隔てている。中間部２６は、曲がって延在していてもよいし、直線状に延在していてもよい。ここでは中間部２６は、第１配線部材１２及び第２配線部材１４の底を結ぶ線に沿って直線状に延在する。別の見方をすると、１つの平面に沿って広がる中間部２６から当該平面に沿って延在する面上に第１配線部材１２及び第２配線部材１４が配設されている。延在方向に沿った中間部２６の寸法は、第１配線部材１２と第２配線部材１４とを離したい距離、すなわち第２配線部材１４によって伝送される信号が第１配線部材１２から受けるノイズの影響が十分に小さくなる距離に応じて適宜設定される。
The intermediate portion 26 is a portion between the first end portion 22 and the second end portion 24. The intermediate portion 26 extends in the direction in which both the first wiring member 12 and the second wiring member 14 are arranged to separate the first wiring member 12 and the second wiring member 14. The intermediate portion 26 may be bent and extend linearly. Here, the intermediate portion 26 extends linearly along a line connecting the bottoms of the first wiring member 12 and the second wiring member 14. From another viewpoint, the first wiring member 12 and the second wiring member 14 are disposed on a surface extending along the plane from the intermediate portion 26 extending along one plane. The dimension of the intermediate portion 26 along the extending direction is the distance at which the first wiring member 12 and the second wiring member 14 are desired to be separated, that is, the noise received from the first wiring member 12 by the signal transmitted by the second wiring member 14. Is appropriately set according to the distance at which the influence of the above becomes sufficiently small.
ここでは、第１端部２２の先端２３と第２端部２４の先端２５と中間部２６とが一箇所で重ねられている。そして、ここでは、当該重ねられた部分が溶着されている。溶着方法は、特に限定されるものではなく、例えば熱溶着であってもよいし、超音波溶着であってもよい。
Here, the tip 23 of the first end 22, the tip 25 of the second end 24, and the intermediate portion 26 are overlapped at one place. Here, the overlapped portion is welded. The welding method is not particularly limited, and for example, heat welding or ultrasonic welding may be used.
図１に示す例では、第１端部２２の先端２３と第２端部２４の先端２５と中間部２６とが、第１端部２２が真ん中に位置するように重なっている。もっとも、第１端部２２の先端２３と第２端部２４の先端２５と中間部２６との重なり方は、上記したものに限られない。第２端部２４が真ん中に位置してもよいし、中間部２６が真ん中に位置してもよい。中間部２６が真ん中に位置する場合、第１端部２２と第２端部２４とはそれぞれ中間部２６の反対側の主面に重ねられる。
In the example shown in FIG. 1, the tip 23 of the first end 22, the tip 25 of the second end 24, and the intermediate portion 26 overlap so that the first end 22 is located in the middle. However, the way in which the tip 23 of the first end 22, the tip 25 of the second end 24 and the intermediate portion 26 overlap is not limited to the above. The second end 24 may be located in the middle, and the intermediate part 26 may be located in the middle. When the intermediate portion 26 is positioned in the middle, the first end portion 22 and the second end portion 24 are overlapped with the main surface on the opposite side of the intermediate portion 26, respectively.
なお、外装部材２０は、シールド材を兼ねていてもよい。例えば、外装部材２０を形成するシート状部材２１がＰＰシート等の基材と、当該基材の一方面に設けられた金属箔等のシールド層とを含むことが考えられる。この場合、第１端部２２と中間部２６とが接合されると共に、第２端部２４と中間部２６とが接合されていることが好ましい。これにより、第１配線部材１２を収容する空間と第２配線部材１４を収容する空間とが配線部材１２、１４の延在方向直交する方向に沿って相互に独立した空間となるため、シールド効果が高くなる。
The exterior member 20 may also serve as a shield material. For example, it is conceivable that the sheet-like member 21 forming the exterior member 20 includes a base material such as a PP sheet and a shield layer such as a metal foil provided on one surface of the base material. In this case, it is preferable that the first end portion 22 and the intermediate portion 26 are joined, and the second end portion 24 and the intermediate portion 26 are joined. Thereby, since the space which accommodates the 1st wiring member 12 and the space which accommodates the 2nd wiring member 14 become mutually independent space along the direction orthogonal to the extension direction of the wiring members 12 and 14, a shielding effect Becomes higher.
また、外装部材２０の周囲には固定、さらには保護等を目的として粘着テープが巻付けられていてもよい。
Further, an adhesive tape may be wound around the exterior member 20 for the purpose of fixing and further protection.

Next, the manufacturing method of the said
まず、図２に示すように、第１配線部材１２と第２配線部材１４とをシート状部材２１の一方面に沿って並行させて配設する。例えば、第１配線部材１２は、外装部材２０が取付けられる部分の外側がそれぞれＵ字状に形成された治具で保持される。同様に第２配線部材１４は、第１配線部材１２と相互に間隔をあけて並行する態様で、外装部材２０が取付けられる部分の外側がそれぞれＵ字状に形成された治具で保持される。シート状部材２１は、これらの治具の間にそれぞれ位置する配線部材１２、１４の下方で載置部８０に載置されている。このとき図２に示す例では、配線部材１２、１４は、シート状部材２１の上面に密着しているが、密着していなくてもよい。
First, as shown in FIG. 2, the first wiring member 12 and the second wiring member 14 are arranged in parallel along one surface of the sheet-like member 21. For example, the 1st wiring member 12 is hold | maintained with the jig | tool in which the outer side of the part to which the exterior member 20 is attached was formed in the U shape, respectively. Similarly, the second wiring member 14 is held in parallel with the first wiring member 12 with a space between each other, and is held by a jig in which the outside of the portion to which the exterior member 20 is attached is formed in a U shape. . The sheet-like member 21 is placed on the placement portion 80 below the wiring members 12 and 14 positioned between these jigs. At this time, in the example illustrated in FIG. 2, the wiring members 12 and 14 are in close contact with the upper surface of the sheet-like member 21, but may not be in close contact.
載置部８０にはスリット８６が設けられている。当該スリット８６は第１配線部材１２と第２配線部材１４との間に位置し、配線部材１２、１４の延在方向に沿って延びる。当該スリット８６は、溶着機構９０によってシート状部材を溶着する際に用いられる。ここでは、載置部８０はシート状部材２１のうち第１配線部材１２の下方に位置する部分が載置される第１載置面８２を有する第１載置部８１と、シート状部材２１のうち第２配線部材１４の下方に位置する部分が載置される第２載置面８４を有する第２載置部８３とで構成されている。第１載置面８２と第２載置面８４とが載置面８２、８４の広がる方向であって、配線部材１２、１４の延在方向と直交する方向に間隔をあけていることで、第１載置面８２と第２載置面８４との間に上記スリット８６が形成されている。
The mounting portion 80 is provided with a slit 86. The slit 86 is located between the first wiring member 12 and the second wiring member 14 and extends along the extending direction of the wiring members 12 and 14. The slit 86 is used when the sheet-like member is welded by the welding mechanism 90. Here, the placement portion 80 includes a first placement portion 81 having a first placement surface 82 on which a portion of the sheet-like member 21 positioned below the first wiring member 12 is placed, and the sheet-like member 21. Among these, it is comprised with the 2nd mounting part 83 which has the 2nd mounting surface 84 in which the part located under the 2nd wiring member 14 is mounted. The first mounting surface 82 and the second mounting surface 84 are spaced in the direction in which the mounting surfaces 82 and 84 spread and are orthogonal to the extending direction of the wiring members 12 and 14. The slit 86 is formed between the first placement surface 82 and the second placement surface 84.
次に、図３に示すように、シート状部材２１の第１端部２２を第１配線部材１２に巻付ける。また、シート状部材２１の第２端部２４を第２配線部材１４に巻付ける。このとき、第１端部２２の先端２３を中間部２６に重ねると共に、第２端部２４の先端２３を中間部２６に重ねる。上述したようにここでは、第１端部２２が真ん中に位置するように重ねているが、必ずしもこの必要はない。第２端部２４が真ん中に位置してもよいし、中間部２６が真ん中に位置してもよい。中間部２６が真ん中に位置する場合、第１端部２２と第２端部２４とはそれぞれ中間部２６の反対側の主面に重ねられる。
Next, as shown in FIG. 3, the first end 22 of the sheet-like member 21 is wound around the first wiring member 12. Further, the second end portion 24 of the sheet-like member 21 is wound around the second wiring member 14. At this time, the tip 23 of the first end 22 is overlapped with the intermediate portion 26, and the tip 23 of the second end 24 is overlapped with the intermediate portion 26. As described above, the first end portion 22 is overlapped so as to be located in the middle here, but this is not always necessary. The second end 24 may be located in the middle, and the intermediate part 26 may be located in the middle. When the intermediate portion 26 is positioned in the middle, the first end portion 22 and the second end portion 24 are overlapped with the main surface on the opposite side of the intermediate portion 26, respectively.
第１端部２２の先端２３と第２端部２４の先端２５と中間部２６とが重なったら、図３に示すように、溶着機構９０で、当該重なり部分を溶着する。図３に示す例では、溶着機構９０は、上型９２と下型９４とで重なり部を挟み込んで溶着する。上型９２は、第１配線部材１２と第２配線部材１４との間に通されて第２端部２４の先端２５の上面を押える。下型９４は上記スリット８６に通されて中間部２６の下面を押える。このとき、上型９２及び下型９４のうち第１端部２２の先端２３側を押える部材（図３に示す例では上型９２）は、押え込みが完了するまでの間に第１端部２２の先端２３を巻き込んで第１配線部材１２に巻付けられた第１端部２２を絞ることが可能であるとよい。これにより、第１端部２２の巻付が強固になり、外装部材２０と第１配線部材１２とが位置ずれしにくくなる。第２配線部材１４に巻付けられた第２端部２４も同様に上型９２又は下型９４によって絞られた状態で溶着されるとよい。なお、絞り込みに関しては、溶着機構９０とは別の治具で行ってもよい。
When the tip 23 of the first end 22, the tip 25 of the second end 24, and the intermediate portion 26 overlap, the overlapping portion is welded by a welding mechanism 90 as shown in FIG. 3. In the example shown in FIG. 3, the welding mechanism 90 is welded by sandwiching an overlapping portion between an upper mold 92 and a lower mold 94. The upper die 92 is passed between the first wiring member 12 and the second wiring member 14 and presses the upper surface of the tip 25 of the second end portion 24. The lower die 94 is passed through the slit 86 and presses the lower surface of the intermediate portion 26. At this time, the member (upper die 92 in the example shown in FIG. 3) that presses the tip 23 side of the first end 22 out of the upper die 92 and the lower die 94 is the first end 22 until the pressing is completed. It is preferable that the first end portion 22 wound around the first wiring member 12 can be squeezed by winding the front end 23 of the wire. Thereby, winding of the 1st end part 22 becomes firm, and it becomes difficult to position-shift the exterior member 20 and the 1st wiring member 12. Similarly, the second end portion 24 wound around the second wiring member 14 may be welded in a state of being squeezed by the upper die 92 or the lower die 94. Note that the narrowing may be performed with a jig different from the welding mechanism 90.
なお、ここでは、第１端部２２の先端２３と第２端部２４の先端２５と中間部２６とを一度に溶着するものとして説明したが、このことは必須ではない。例えば、第１端部２２の先端２３と中間部２６とを溶着した後、第１端部２２の先端２３と第２端部２４の先端２５と中間部２６とを溶着するものであってもよい。
In addition, although demonstrated here that the front-end | tip 23 of the 1st end part 22, the front-end | tip 25 of the 2nd end part 24, and the intermediate part 26 were welded at once, this is not essential. For example, after the tip 23 of the first end 22 and the intermediate portion 26 are welded, the tip 23 of the first end 22, the tip 25 of the second end 24, and the intermediate portion 26 are welded. Good.
以上より、外装部材２０の中間部２６で第１配線部材１２及び第２配線部材１４を離しつつ、外装部材２０が第１配線部材１２及び第２配線部材１４に外装される。
As described above, the exterior member 20 is externally attached to the first wiring member 12 and the second wiring member 14 while separating the first wiring member 12 and the second wiring member 14 at the intermediate portion 26 of the exterior member 20.
このように構成されたワイヤーハーネス１０によると、中間部２６が第１配線部材１２と第２配線部材１４との間で両者が並ぶ方向に延在して第１配線部材１２と第２配線部材１４とを隔てるように形成されているため、第１配線部材１２と第２配線部材１４とを中間部２６の延在方向に沿った長さ寸法分離すことができる。従って、シート状部材２１を用いて複数の配線部材を離して配設する際、シート状部材２１の厚みより大きく離すことができる。
According to the wire harness 10 configured as described above, the intermediate portion 26 extends in the direction in which both are arranged between the first wiring member 12 and the second wiring member 14, so that the first wiring member 12 and the second wiring member are arranged. 14, the first wiring member 12 and the second wiring member 14 can be separated in the length dimension along the extending direction of the intermediate portion 26. Therefore, when the plurality of wiring members are separated from each other using the sheet-like member 21, it can be separated from the thickness of the sheet-like member 21.
また、第１端部２２及び第２端部２４と中間部２６とが溶着されているため、第１端部２２及び第２端部２４がそれぞれ第１配線部材１２及び第２配線部材１４を覆う状態を維持する機構を容易に付与することができる。
Further, since the first end portion 22 and the second end portion 24 and the intermediate portion 26 are welded, the first end portion 22 and the second end portion 24 connect the first wiring member 12 and the second wiring member 14, respectively. A mechanism for maintaining the covering state can be easily provided.
また、第３の態様によると、第１端部２２の先端２３と第２端部の先端２５と中間部２６とが重ねられているため、第１配線部材１２と第２配線部材１４とを離す中間部２６の剛性を高めることができる。
Moreover, according to the 3rd aspect, since the front-end | tip 23 of the 1st end part 22, the front-end | tip 25 of the 2nd end part, and the intermediate part 26 are piled up, the 1st wiring member 12 and the 2nd wiring member 14 are connected. The rigidity of the intermediate part 26 to be separated can be increased.

実施形態に係るワイヤーハーネス１０において、第３配線部材１８を配設することも考えられる。図４には、中間部２６に第３配線部材１８を配設したワイヤーハーネス１０Ａが示されている。 {Modifications}
In the
具体的には、ワイヤーハーネス１０Ａは、第３配線部材１８をさらに備える。また、ワイヤーハーネス１０Ａは、被覆部材３０をさらに備える。
Specifically, the wire harness 10 </ b> A further includes a third wiring member 18. The wire harness 10 </ b> A further includes a covering member 30.
第３配線部材１８は、中間部２６上に配設され、第１配線部材１２及び第２配線部材１４と並行する。かかる第３配線部材１８としては、第１配線部材１２よりも第２配線部材１４に与えるノイズの影響が小さいものであって、第２配線部材１４よりも第１配線部材１２から受けるノイズの影響が小さいものが好ましい。このような、第１配線部材１２、第２配線部材１４、第３配線部材１８の組み合わせとしては、例えば、第１配線部材１２が高電圧系の電源線であり、第２配線部材１４が信号線であり、第３配線部材１８が低電圧系の電源線である組み合わせが考えられる。また、例えば、第１配線部材１２が電源線であり、第２配線部材１４が高速通信用の信号線などのノイズの影響を受けやすい信号線であり、第３配線部材１８がセンサ用の信号線又は低速通信用の信号線などのノイズの影響を受けにくい信号線である組み合わせが考えられる。
The third wiring member 18 is disposed on the intermediate portion 26 and is parallel to the first wiring member 12 and the second wiring member 14. The third wiring member 18 is less affected by noise on the second wiring member 14 than the first wiring member 12, and is affected by noise received from the first wiring member 12 than the second wiring member 14. Is preferably small. As such a combination of the first wiring member 12, the second wiring member 14, and the third wiring member 18, for example, the first wiring member 12 is a high-voltage power supply line, and the second wiring member 14 is a signal. A combination in which the third wiring member 18 is a low-voltage power supply line is conceivable. Further, for example, the first wiring member 12 is a power line, the second wiring member 14 is a signal line that is susceptible to noise such as a signal line for high-speed communication, and the third wiring member 18 is a signal for a sensor. A combination that is a signal line that is not easily affected by noise, such as a line or a signal line for low-speed communication, can be considered.
被覆部材３０は、外装部材２０及び第３配線部材１８の周囲を覆う。かかる被覆部材３０としては、ここでは、粘着テープであるものとして説明する。もっとも被覆部材３０は、コルゲートチューブ又は硬質チューブ等の筒状部材等であってもよいし、シート状部材２１を巻き付けたものであってもよい。
The covering member 30 covers the periphery of the exterior member 20 and the third wiring member 18. Here, the covering member 30 will be described as an adhesive tape. However, the covering member 30 may be a cylindrical member such as a corrugated tube or a hard tube, or may be a member around which the sheet-like member 21 is wound.
このようなワイヤーハーネス１０Ａによると、第３配線部材１８を容易に追加することができる。
According to such a wire harness 10A, the third wiring member 18 can be easily added.
また、外装部材２０及び第３配線部材１８の周囲を覆う被覆部材３０をさらに備えるため、第１配線部材１２、第２配線部材１４及び第３配線部材１８の位置関係を維持しやすくなる。
Moreover, since the covering member 30 that covers the periphery of the exterior member 20 and the third wiring member 18 is further provided, the positional relationship among the first wiring member 12, the second wiring member 14, and the third wiring member 18 can be easily maintained.
また、実施形態において、第１端部２２、第２端部２４及び中間部２６が溶着されているものとして説明したが、このことは必須ではない。第１端部２２、第２端部２４及び中間部２６が両面粘着テープ、接着剤、又は凹部と凸部とによる係合等、溶着以外の方法で接合されていてもよい。また、第１端部２２、第２端部２４及び中間部２６が接合されなくてもよい。この場合、被覆部材３０等の外装部材２０に外装される部材で、外装部材２０の巻付け形態を維持することが考えられる。
In the embodiment, the first end portion 22, the second end portion 24, and the intermediate portion 26 are described as being welded, but this is not essential. The first end portion 22, the second end portion 24, and the intermediate portion 26 may be joined by a method other than welding, such as double-sided pressure-sensitive adhesive tape, adhesive, or engagement between a concave portion and a convex portion. Moreover, the 1st end part 22, the 2nd end part 24, and the intermediate part 26 do not need to be joined. In this case, it is conceivable to maintain the winding form of the exterior member 20 with a member that is exteriorly mounted on the exterior member 20 such as the covering member 30.
また、実施形態において、第１端部２２、第２端部２４及び中間部２６が一箇所で重なっているものとして説明したが、このことは必須ではない。第１端部２２及び中間部２６の重なり部分と、第２端部２４及び中間部２６の重なり部分とが中間部２６の延在方向に沿って離れていてもよい。この場合、第１端部２２及び第２端部２４は、中間部２６の同じ主面に重なっていてもよいし、相互に反対側の主面に重なっていてもよい。また、各端部２２、２４と中間部２６とは重なっていなくてもよい。この場合、各端部２２、２４の先端２３、２５は各端部２２、２４が覆う各配線部材１２、１４に固定されることが考えられる。
In the embodiment, the first end portion 22, the second end portion 24, and the intermediate portion 26 are described as overlapping at one place, but this is not essential. The overlapping portion of the first end portion 22 and the intermediate portion 26 and the overlapping portion of the second end portion 24 and the intermediate portion 26 may be separated along the extending direction of the intermediate portion 26. In this case, the first end 22 and the second end 24 may overlap the same main surface of the intermediate portion 26, or may overlap the opposite main surfaces. Moreover, each end part 22 and 24 and the intermediate part 26 do not need to overlap. In this case, it is conceivable that the tips 23 and 25 of the end portions 22 and 24 are fixed to the wiring members 12 and 14 covered by the end portions 22 and 24.
また、実施形態において、中間部２６は、第１配線部材１２及び第２配線部材１４の底を結ぶ線上に沿って延在するものとして説明したが、このことは必須ではない。例えば、中間部２６は、第１配線部材１２及び第２配線部材１４の各中心軸を結ぶ線に沿って延在するものであってもよい。このような外装部材を備えるワイヤーハーネスは、例えば、上記載置部８０の各載置面８２、８４に第１配線部材１２及び第２配線部材１４の半周面に応じた横断面半円状の溝を形成するなどすることで製造可能である。
In the embodiment, the intermediate portion 26 has been described as extending along a line connecting the bottoms of the first wiring member 12 and the second wiring member 14, but this is not essential. For example, the intermediate portion 26 may extend along a line connecting the central axes of the first wiring member 12 and the second wiring member 14. A wire harness provided with such an exterior member has, for example, a semicircular cross section corresponding to the semicircular surfaces of the first wiring member 12 and the second wiring member 14 on the mounting surfaces 82 and 84 of the mounting portion 80 described above. It can be manufactured by forming a groove.
また、実施形態において外装部材２０の各端部２２、２４が各配線部材１２、１４に巻付けられるものとして説明したが、このことは必須ではない。外装部材２０の剛性が高い場合、外装部材２０の各端部２２、２４は、屈曲しつつ各配線部材１２、１４を覆うことが考えられる。
In the embodiment, the end portions 22 and 24 of the exterior member 20 are described as being wound around the wiring members 12 and 14, but this is not essential. When the exterior member 20 has high rigidity, it is conceivable that the end portions 22 and 24 of the exterior member 20 cover the wiring members 12 and 14 while being bent.
なお、上記実施形態及び各変形例で説明した各構成は、相互に矛盾しない限り適宜組み合わせることができる。
In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.
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.
