Abstract

第１配線部材と第２配線部材とを、間隔をあけて配設できるようにすることを目的とする。ワイヤーハーネスは、第１配線部材と、第１配線部材に対して並列して配置された第２配線部材と、第１配線部材と第２配線部材との間に配設された第３配線部材と、第１配線部材と第２配線部材と第３配線部材の並列体の一方面側から第３配線部材を覆うと共に、第１配線部材と第３配線部材との間、及び、第２配線部材と第３配線部材との間を通って、並列体の他方面側から第１配線部材と第２配線部材とを覆うシート状配列維持部材とを備える。

Description

ワイヤーハーネス
　この発明は、第１配線部材と第２配線部材とを離して配設する技術に関する。
　特許文献１は、低電圧系回路の複数の電線と、高電圧系回路の複数の電線とを有し、これら低電圧系回路の複数の電線と高電圧系回路の複数の電線とを同一の経路に沿って配索するワイヤーハーネスであって、前記低電圧系回路の複数の電線と前記高電圧系回路の複数の電線とを分けると共に、これら低電圧系回路の複数の電線と高電圧系回路の複数の電線との全外周を別々に包み込むよう折り曲げた絶縁シートによって外装を施したワイヤーハーネスを開示している。このワイヤーハーネスでは、低電圧系回路の複数の電線と高電圧系回路の複数の電線とは互いに分離され、且つ、双方の間に絶縁シートが介在されることから比較的大きい沿面距離を持って配置される。
特開２００４－３５５８３９号公報
　ところで、電線間において、電磁ノイズの影響を避けるためには、電線間の空間距離を設けることが好ましい。特許文献１に開示の技術では、低電圧系回路の複数の電線と、高電圧系回路の複数の電線との間には、絶縁シートの厚み分の空間距離を確保できることができるだけであるので、ノイズ対策として不十分となる恐れがある。
　そこで、本発明は、第１配線部材と第２配線部材とを、間隔をあけて配設できるようにすることを目的とする。
　上記課題を解決するため、第１の態様に係るワイヤーハーネスは、第１配線部材と、前記第１配線部材に対して並列して配置された第２配線部材と、前記第１配線部材と前記第２配線部材との間に配設された第３配線部材と、前記第１配線部材と前記第２配線部材と前記第３配線部材の並列体の一方面側から前記第３配線部材を覆うと共に、前記第１配線部材と前記第３配線部材との間、及び、前記第２配線部材と前記第３配線部材との間を通って、前記並列体の他方面側から前記第１配線部材と前記第２配線部材とを覆うシート状配列維持部材とを備える。
　第２の態様は、第１の態様に係るワイヤーハーネスであって、前記第１配線部材は、ノイズ源となる配線部材であり、前記第２配線部材は、ノイズの影響を受ける配線部材とされている。
　第３の態様は、第１又は第２の態様に係るワイヤーハーネスであって、前記シート状配列維持部材は、前記並列体の外周囲を覆う側方延長覆い部を含む。
　第４の態様は、第１から第３のいずれか１つの態様に係るワイヤーハーネスであって、前記並列体の外周囲を覆う覆い部をさらに備える。
　第１の態様によると、シート状配列維持部材が、第１配線部材と第２配線部材と第３配線部材の並列体の一方面側から第３配線部材を覆うと共に、第１配線部材と第３配線部材との間、及び、第２配線部材と第３配線部材との間を通って、並列体の他方面側から第１配線部材と第２配線部材とを覆う。このため、第３配線部材が、第１配線部材と第２配線部材との間から並列体の一方面側に脱し難くなる。これにより、第１配線部材と第２配線部材と第３配線部材との並列状態が維持され易くなる。そして、第１配線部材と第２配線部材との間に第３配線部材が介在するため、第１配線部材と第２配線部材とを、第３配線部材分の間隔をあけて配設できる。
　第２の態様によると、第１配線部材から第２配線部材へのノイズの影響を少なくできる。
　第３の態様によると、側方延長覆い部によって並列体の外周囲を覆って保護することができる。
　第４の態様によると、覆い部によって並列体の外周囲を覆って保護することができる。

　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はワイヤーハーネス１０を示す概略平面図であり、図２は図１のＩＩ－ＩＩ線概略断面図である。
　ワイヤーハーネス１０は、第１配線部材２０と、第２配線部材３０と、第３配線部材４０と、シート状配列維持部材５０とを備える。第１配線部材２０と第２配線部材３０との間には第３配線部材４０が設けられており、第１配線部材２０と第２配線部材３０とが間隔をあけて並列状態に配設されている。これにより、第１配線部材２０と第２配線部材３０間のノイズの影響を低減可能となっている。なお、ワイヤーハーネス１０の端部等において、第１配線部材２０と第２配線部材３０と第３配線部材４０とが分岐していてもよい。第１配線部材２０、第２配線部材３０及び第３配線部材４０の端部は、コネクタ等を介して車両等に搭載された各種電気部品等に接続される。つまり、ワイヤーハーネス１０は、車両において各種電気部品等を電気的に接続する配線として用いられる。
　第１配線部材２０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２１を含む配線部材である。本実施形態においては、第１配線部材２０は、複数の電線２１が束ねられた構成である例で説明する。
　第２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２１を含む配線部材である。本実施形態においては、第２配線部材３０は、複数（例えば、２本）の電線２１が撚り合わされると共にその外周にシース２２が形成されたツイスト電線２４である例で説明する。本第２配線部材３０の少なくとも一部は、上記第１配線部材２０に対して並列して配設される。
　第３配線部材４０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２１を含む配線部材である。本実施形態においては、第３配線部材４０は、複数の電線２１が束ねられた構成である例で説明する。なお、図２では、第３配線部材４０は、第１配線部材２０よりも細く、第２配線部材３０よりも太い。もっとも、第１配線部材、第２配線部材、第３配線部材の太さは上記例に限られない。例えば、第３配線部材が第１及び第２配線部材よりも太くてもよい。
　この第３配線部材４０の少なくとも一部は、第１配線部材２０と第２配線部材３０との間に配設されている。このため、第１配線部材２０、第２配線部材３０及び第３配線部材４０は、同一平面上において並列するように配設された部分を含む。第１配線部材２０、第２配線部材３０及び第３配線部材４０が並列配置された部分を、並列体１８ということとする。
　上記第１配線部材２０と第２配線部材３０との関係で説明すると、第１配線部材２０はノイズ源となりやすい部材であり、第２配線部材３０は第１配線部材２０からのノイズの影響を受けやすい部材であることが考えられる。このような配線部材２０、３０の組み合わせとしては、例えば、第１配線部材２０が電源線を含み、第２配線部材３０の信号線を含むものである例が挙げられる。また、第１配線部材２０が高電圧系の電源線を含み、第２配線部材３０がそれよりも低電圧系の電源線を含むものである例が挙げられる。
　さらに、第１配線部材２０、第２配線部材３０及び第３配線部材４０との関係で説明すると、第３配線部材４０としては、第１配線部材２０よりも第２配線部材３０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３０よりも第１配線部材２０から受けるノイズの影響が小さいものである例が挙げられる。このような、第１配線部材２０、第２配線部材３０、第３配線部材４０の組み合わせとしては、例えば、第１配線部材２０が高電圧系の電源線であり、第２配線部材３０が信号線であり、第３配線部材４０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２０が電源線であり、第２配線部材３０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４０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。
　ここでは、第１配線部材２０が電源線を含み、第２配線部材３０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３０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り、第３配線部材４０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を含む例で説明する。
　シート状配列維持部材５０は、上記並列体１８の一方面側（図２の上側）から第３配線部材４０を覆うと共に、第１配線部材２０と第３配線部材４０との間、及び、第２配線部材３０と第３配線部材４０との間を通って、並列体１８の他方面側（図２の下側）から第１配線部材２０と第３配線部材４０とを覆う。これにより、第３配線部材４０が並列体１８の上方に移動することを抑制すると共に、第１配線部材２０及び第２配線部材３０が並列体１８の下方に移動することを抑制し、もって、第１配線部材２０、第２配線部材３０及び第３配線部材４０が並列状態を保つようにする役割を果す。
　より具体的には、シート状配列維持部材５０は、細長いシート状に形成されている。シート状配列維持部材５０は、割れることなく曲げ可能なシート状部材により形成される。かかるシート状配列維持部材５０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、内部が一様に樹脂で埋まっている樹脂製シート材（樹脂製フィルム等の薄手のものを含む）、プラスチックダンボール等の中空板材、発泡シート、不織布等を用いることができる。本実施形態では、シート状配列維持部材５０は、緩やかにカーブを描くように曲げられているが、折目を介して曲げられていてもよい。また、シート状配列維持部材５０として、金属蒸着、金属メッキ等によって導電性が付与されたものが用いられてもよい。
　ここでは、シート状配列維持部材５０は、シート本体部５２と、側方延長覆い部５６とを備える。
　シート本体部５２は、長方形状に形成されている。シート本体部５２の長さ寸法は、第１配線部材２０、第２配線部材３０及び第３配線部材４０のうち本シート状配列維持部材５０によって並列状態が維持される部分の長さ寸法と同じに設定されている。シート本体部５２の幅寸法は、第１配線部材２０、第２配線部材３０及び第３配線部材４０のそれぞれを半分程度覆える程度の長さ以上に設定されている。
　シート本体部５２の幅方向中間部は、並列体１８の一方面側（図２の上側）から第３配線部材４０を半周程度覆っている。シート本体部５２のうち第３配線部材４０を覆う部分の両側部は、第１配線部材２０と第３配線部材４０との間、及び、第２配線部材３０と第３配線部材４０との間を、並列体１８の一方面側から他方面側（図２では上から下へ）へと通っている。そして、シート本体部５２の両側部が、並列体１８の他方面側（図２では下側）から第１配線部材２０及び第２配線部材３０を半周程度又は半周を超える程度覆っている。
　側方延長覆い部５６は、シート本体部５２の一側部から外方に延出する長方形状に形成されている。ここでは、側方延長覆い部５６の長さ寸法は、シート本体部５２の長さ寸法と同じに設定されている。もっとも、側方延長覆い部の長さ寸法は、シート本体部５２の長さ寸法より大きくてもよいし、小さくてもよい。また、シート本体部の一側部の一部にのみ、側方延長覆い部が設けられていてもよい。側方延長覆い部５６の幅寸法は、並列体１８の外周部を一周以上覆える大きさに設定されている。
　側方延長覆い部５６は、シート本体部５２の一側部から延出して、並列体１８の全体の外周を覆うように曲げられている。側方延長覆い部５６の端部は、両面テープ等の接合部５７によって、側方延長覆い部５６のうち巻付け済の部分の外周に接合されている。側方延長覆い部５６の端部は、接着剤、熱溶着等によって側方延長覆い部５６のうち巻付け済の部分の外周に接合されてもよい。また、側方延長覆い部５６の外周に粘着テープ、結束バンド等の結束部材を巻付けることによって、側方延長覆い部５６が並列体１８を覆う状態が維持されてもよい。
　図３から図５は、上記ワイヤーハーネス１０の製造方法例を示す説明図である。
　まず、図３に示すように、ワイヤーハーネス組立図板等に組込まれた作業台６０上に、第３配線部材４０を載置する。
　そして、図４に示すように、作業台６０上で、第３配線部材４０の上側からシート状配列維持部材５０のシート本体部５２を被せる。この状態では、シート本体部５２の幅方向中間部が第２配線部材３０を上側から覆い、シート本体部５２の両側部及び側方延長覆い部５６が第３配線部材４０の両側で作業台６０上に配設された状態となる。
　次に図５に示すように、第３配線部材４０の両側であってシート本体部５２の幅方向両側部に、第１配線部材２０及び第２配線部材３０を載置する。この後、シート本体部５２の両側部を第１配線部材２０及び第２配線部材３０の周囲に被せ、さらに、側方延長覆い部５６によって、第１配線部材２０、第２配線部材３０及び第３配線部材４０を覆う。そして、側方延長覆い部５６の端部を両面テープ等によって側方延長覆い部５６のうちの巻付け済の部分に接合する。あるいは、側方延長覆い部５６の周囲に粘着テープ等の結束部材を巻付けて結束状態に維持する。
　このようにして、ワイヤーハーネス１０を容易に製造することができる。
　以上のように構成されたワイヤーハーネス１０によると、シート状配列維持部材５０のシート本体部５２が、並列体１８の一方面側から第３配線部材４０を覆うと共に、第１配線部材２０と第３配線部材４０との間、及び、第２配線部材３０と第３配線部材４０との間を通って、並列体１８の他方面側から第１配線部材２０と第２配線部材３０とを覆う。このため、第３配線部材４０が、第１配線部材２０と第２配線部材３０との間から並列体１８の一方面側に脱し難くなる。これにより、第１配線部材２０、第２配線部材３０及び第３配線部材４０の並列状態が維持され易くなる。また、第１配線部材２０と第２配線部材３０との間に第３配線部材４０が介在するため、第１配線部材２０と第２配線部材３０とを、第３配線部材４０の直径寸法分の間隔をあけて配設することができる。これにより、第１配線部材２０と第２配線部材３０との間でのノイズの影響、特に、第１配線部材２０から第２配線部材３０へのノイズの影響を低減できる。
　なお、配線部材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、第１配線部材２０と第２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、第１配線部材２０と第２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、第１配線部材２０及び第２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。
　また、側方延長覆い部５６によって並列体１８の外周囲を覆って保護することができる。側方延長覆い部５６は、第１配線部材２０と第２配線部材３０との間に第３配線部材４０が配設された並列体１８の外周囲を覆うことによって、第３配線部材４０が並列体１８の他方面側に脱することを抑制し、もって、第１配線部材２０、第２配線部材３０及び第３配線部材４０の並列形態をより確実に維持する役割をも果す。
　｛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。このワイヤーハーネス１１０では、上記シート状配列維持部材５０に代えて、次のシート状配列維持部材１５０が用いられている。シート状配列維持部材１５０は、上記シート状配列維持部材５０において、側方延長覆い部５６を省略し、シート本体部５２に対応する部分のみを備えた構成とされている。そして、シート状配列維持部材１５０が上記シート本体部５２と同様の態様にて、第１配線部材２０、第２配線部材３０及び第３配線部材４０を覆っており、これにより、第１配線部材２０、第２配線部材３０及び第３配線部材４０が並列形態に保たれている。
　また、ワイヤーハーネス１１０は、シート状配列維持部材１５０とは別に覆い部１５６を備える。覆い部１５６は、第１配線部材２０、第２配線部材３０及び第３配線部材４０の並列体１８の外周囲を覆っている。覆い部１５６の巻き終り側の端部は、覆い部１５６のうち巻始め側の部分の外周に、両面テープ等によって接合されている。これにより、並列体１８が覆い部１５６によって保護される。また、並列体１８の形態がより確実に保たれるようになっている。
　覆い部１５６を設ける代りに、並列体１８の外周に粘着テープ、結束バンド等の結束部材を巻付けるようにしてもよい。
　また、上記実施形態及び変形例において、並列体１８を覆うシート状配列維持部材５０、１５０が、並列体１８を覆う向きを交互に変えて複数設けられてもよい。
　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。
