本発明は、強化繊維樹脂等の樹脂ボディを備えた車両に適用するのに適したワイヤーハーネスとアース部材の配索構造に関する。   The present invention relates to a wiring harness and a grounding member wiring structure suitable for application to a vehicle having a resin body such as a reinforced fiber resin.

従来、金属製のボディを備えた車両（自動車）において、バッテリ駆動する電装機器（補機）のアース接続のために、バッテリのマイナス端子に接続したボディをアース回路（グランド）として利用するのが一般的であった。   Conventionally, in a vehicle (automobile) having a metal body, the body connected to the negative terminal of the battery is used as an earth circuit (ground) for earth connection of battery-powered electrical equipment (auxiliary equipment). It was general.

しかし、強化繊維樹脂等の合成樹脂を用いて一体形成した樹脂ボディを備えた車両があるが、このような樹脂ボディでは導電性はあるものの抵抗値が高い、抵抗値が安定しないなどの理由で、アースとしての機能を満たさない。このため、例えば特開２００９−１８４６１１号公報（特許文献１）に開示されているように、様々なアース構造が提案されている。   However, there are vehicles equipped with a resin body integrally formed using a synthetic resin such as a reinforced fiber resin, but such a resin body is conductive but has a high resistance value and the resistance value is not stable. Does not fulfill the function of earth. For this reason, various ground structures have been proposed as disclosed in, for example, Japanese Patent Application Laid-Open No. 2009-184611 (Patent Document 1).

FIG. 1 is a perspective view showing a part of a wire harness and a ground member according to a first embodiment of the present invention. The ground member 1 of this embodiment is formed as a long member having an L-shaped cross section composed of a bottom plate 11 and a side plate 12 by a conductive member such as aluminum. The ground member 1 has an opening 1 </ b> A sandwiched between the edge of the bottom plate 11 and the edge of the side plate 12.

Further, since the ground member 1 surrounds a part of the wire harness 10 around the axis L, the wire harness 10 can be protected. Furthermore, since the earth member 1 is composed of a conductive member, it can block electromagnetic waves and the like, and is also an EMC measure.

図２は本発明の第２実施形態のワイヤーハーネスとアース部材の一部を示す斜視図である。この実施形態のアース部材２は、例えばアルミニウム等の導電性部材により構成され、底板２１と、２つの側板２２，２３と、傾斜壁２４，からなる。このアース部材２は、側板２２の縁と傾斜壁２４の縁とに挟まれた開口部２Ａを有している。すなわち、アース部材２はその長手方向の軸Ｌに沿ってアース部材２の全長に沿って開口部２Ａを有している。   FIG. 2 is a perspective view showing a part of the wire harness and the ground member according to the second embodiment of the present invention.

Moreover, since the earth member 2 surrounds a part of the wire harness 10 around the axis L, the wire harness 10 can be protected. Furthermore, since the earth member 2 is composed of a conductive member, it can block electromagnetic waves and the like, and is also an EMC measure. At this time, by adjusting the angle of the inclined plate 24 and the height of the side plate 22, it is possible to take EMC countermeasures against electromagnetic waves coming from an arbitrary direction.

The ground member 4 of this embodiment is formed in a circular arc shape whose cross section is approximately three-quarters of a circle by a conductive member such as aluminum. The ground member 4 has an opening 4A sandwiched between both edges parallel to the axis L. That is, the earth member 4 has an opening 4A along the entire length of the earth member 4 along the longitudinal axis L thereof.

また、アース部材４はその内側に凹部４Ｂを有しており、この凹部４Ｂ内にワイヤーハーネス１０が配設されている。すなわち、ワイヤーハーネス１０は、アース部材４に沿ってこのアース部材４の内側に配置されている。このように、アース部材４はワイヤーハーネス１０の軸Ｌ回りの一部を囲っている。また、アース部材４には各種電装機器（補機）ｂが電気的に接続される。   The ground member 4 has a recess 4B inside thereof, and the wire harness 10 is disposed in the recess 4B.

アース部材４とワイヤーハーネス１０を車両のボディに配索するときは、アース部材４の開口部４Ａからワイヤーハーネス１０をこのアース部材４の内側に配置できるので、容易に配索することができる。また、アース部材４はワイヤーハーネス１０の軸Ｌ回りの一部を囲っているので、このワイヤーハーネス１０を保護することもできる。さらに、アース部材４は導電性部材で構成されているので、電磁波等を遮断することができ、ＥＭＣ対策にもなる。開口部４Ａを蓋部材４１で埋めることで、異物等の侵入を防ぐなどの外装機能の補強ができる。さらに、この蓋部材４１を、導電性部材とすることで、回折による電磁波の侵入を防ぐことができ、さらなるＥＭＣ対策にもなる。   When routing the ground member 4 and the wire harness 10 to the body of the vehicle, the wire harness 10 can be placed inside the ground member 4 from the opening 4A of the ground member 4, so that it can be easily routed. Further, since the ground member 4 surrounds a part of the wire harness 10 around the axis L, the wire harness 10 can be protected. Furthermore, since the earth member 4 is composed of a conductive member, it can block electromagnetic waves and the like, and is also an EMC measure. By filling the opening 4 </ b> A with the lid member 41, it is possible to reinforce the exterior function such as preventing the entry of foreign matters and the like. Furthermore, by using the lid member 41 as a conductive member, it is possible to prevent intrusion of electromagnetic waves due to diffraction, which is a further EMC measure.
