Description

本発明は、車両用アース部材の配索構造及び車両用アース部材に関するものである。   The present invention relates to a wiring structure for a vehicle ground member and a vehicle ground member.

従来、車両に搭載される電装部品とバッテリとを電気的に接続するために、バッテリが接続された金属製の車体に電装部品を接続するボディアースを行うのが一般的であった。   BACKGROUND ART Conventionally, in order to electrically connect an electric component mounted on a vehicle and a battery, it has been common practice to perform body grounding for connecting the electric component to a metal vehicle body to which the battery is connected.

ところが、近年、軽量化を図るために車体を樹脂で形成した車両が提案されている。このような車両においては、従来の金属製の車体のようにボディアースすることができない。そこで、例えば、図５に示すように、バッテリの負極に接続された導電性の車両用アース部材１００を車体に配置し、この車両用アース部材１００に電装部品のアース電線を接続することが考えられている。   However, in recent years, there has been proposed a vehicle in which a vehicle body is formed of resin in order to reduce the weight. In such a vehicle, the body cannot be grounded like a conventional metal body. Therefore, for example, as shown in FIG. 5, it is conceivable to arrange a conductive vehicle ground member 100 connected to the negative electrode of the battery on the vehicle body and connect a ground wire of an electrical component to the vehicle ground member 100. Have been.

車両にはドア内にモータ等の電装部品が集まっている。そこで、従来、車両用アース部材１００としては、棒状に設けて、図５（Ａ）に示すように、車体１０１の幅方向の両端に車両の進行方向に沿って配置していた。しかしながら、このような配置では、図５（Ｂ）に示すように、側面衝突などの事故が発生すると、車両用アース部材１００が断線して、複数の電装部品が動作しなくなる恐れがあった。   In a vehicle, electrical components such as a motor are gathered in a door. Therefore, conventionally, the vehicle grounding member 100 is provided in a rod shape and disposed at both ends in the width direction of the vehicle body 101 along the traveling direction of the vehicle as shown in FIG. However, in such an arrangement, as shown in FIG. 5B, when an accident such as a side collision occurs, the vehicle ground member 100 may be disconnected, and a plurality of electrical components may not operate.

そこで、バッテリと、同じ電装部品と、の間を複数の車両用アース部材１００で別々に接続して、側面衝突が発生して、１つが断線しても、残りが断線せずに電装部品が動作させることも考えられる。しかしながら、車両用アース部材１００の数が増え、コスト的にも重量的にも問題があった。   Therefore, the battery and the same electrical component are separately connected by a plurality of vehicle ground members 100, so that a side collision occurs, and even if one is disconnected, the remaining electrical components are disconnected without disconnection. It is also conceivable to make it work. However, the number of vehicle ground members 100 has increased, and there have been problems in terms of cost and weight.

そこで、本発明は、側面衝突などの外的要因による車両用アース部材の断線が生じにくくなる車両用アース部材の配索構造及び車両用アース部材を提供することを課題とする。   SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle grounding member wiring structure and a vehicle grounding member in which disconnection of the vehicle grounding member due to an external factor such as a side collision hardly occurs.
