本発明はシールドパイプ端末における電線保護構造に関し、詳しくは、シールドパイプに挿通され端末から引き出される電線が該シールドパイプの端末のエッジに当接して損傷するのを防止するものである。
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire protection structure for a shield pipe end, and more particularly, to prevent an electric wire inserted through a shield pipe and drawn from the end from coming into contact with the edge of the end of the shield pipe.
従来、ハイブリッド自動車や電気自動車では、バッテリとインバータとの間やインバータとモータとの間などに配索されるワイヤハーネスの複数本の電線を金属製のシールドパイプに挿通して配線する場合が多い。例えば、特開2006-311699号公報(特許文献1)では、車体の床下に沿った配線経路で図5に示すような金属製のシールドパイプ101に複数本の電線100を挿通し、エンジンルーム内などスペースに余裕のない屈曲した配線経路では前記シールドパイプ101の端部に接続した金属編組線からなる可撓性シールド部材102に前記電線100を挿通して配線している。さらに、防水や電線保護の目的で、前記可撓性シールド部材102にゴム製のグロメット103を外装している。
Conventionally, in hybrid vehicles and electric vehicles, there are many cases where a plurality of wires of a wire harness routed between a battery and an inverter or between an inverter and a motor are inserted through a metal shield pipe and wired. . For example, in Japanese Patent Laid-Open No. 2006-311699 (Patent Document 1), a plurality of electric wires 100 are inserted through a metal shield pipe 101 as shown in FIG. For example, in a bent wiring path having no space, the electric wire 100 is inserted through the flexible shield member 102 made of a metal braided wire connected to the end of the shield pipe 101. Further, a rubber grommet 103 is externally attached to the flexible shield member 102 for the purpose of waterproofing and electric wire protection.
しかし、円筒状のシールドパイプ101内に挿通される複数本の電線100の周囲には隙間Aが形成されており、車体の振動等によってシールドパイプ101内の電線100が互いに干渉しながらパイプ径方向に移動したり、引き出された電線100の配線方向等によってシールドパイプ101内に挿通される複数本の電線100がパイプ径方向に傾いたりする場合があり、これによりシールドパイプ101の端末エッジ101aに電線100が当接して損傷するおそれがある。
However, a gap A is formed around the plurality of electric wires 100 inserted into the cylindrical shield pipe 101, and the electric wires 100 in the shield pipe 101 interfere with each other due to vibration of the vehicle body and the like in the pipe radial direction. Or the plurality of wires 100 inserted into the shield pipe 101 may be inclined in the pipe radial direction depending on the wiring direction of the drawn wire 100, etc. There is a possibility that the electric wire 100 may be abutted and damaged.
本発明は、シールドパイプに挿通される複数本の電線が該シールドパイプの端末エッジに当接して損傷するのを防止することを課題としている。

前記課題を解決するため、本発明は、ハイブリッド自動車または電気自動車に配索する複数本の電線からなるワイヤハーネスがシールドパイプに挿通され、
該シールドパイプに挿通される前記複数本の電線には、該電線の外周面と前記シールドパイプの端末エッジとの間に介在させる樹脂材またはゴム材がモールド成形されていることを特徴とするシールドパイプ端末における電線保護構造を提供している。 In order to solve the above problems, the present invention is a wire harness composed of a plurality of electric wires arranged in a hybrid vehicle or an electric vehicle is inserted into a shield pipe,

The partition walls are formed in a radial cross section, and each partition wall is a shielded pipe with a partition provided with at least one bent portion continuous in the pipe axis direction,

さらに、前記のように、シールドパイプの周壁および隣接する2枚の仕切壁で囲まれる電線挿通空間に1本ずつ挿通される電線に、シールドパイプの周壁および隣接する2枚の仕切壁の端末エッジと前記電線の外周面との間に介在させる樹脂材またはゴム材をモールド成形しておくことで、前記電線挿通空間に挿通される各電線が前記シールドパイプの周壁および仕切壁の端末エッジに当接して損傷することを効果的に防止できる。 As described above, as the shield pipe through which the plurality of electric wires are inserted, a plurality of partition walls corresponding to the number of electric wires to be inserted project radially from the inner surface of the peripheral wall of the shield pipe, and a plurality of the partition walls are provided by the partition walls. By separating the wires in the shield pipe one by one, the wires in the shield pipe do not move in the radial direction of the pipe while interfering with each other, and each wire is partitioned in the shield pipe. By aligning them in parallel, the movement of the electric wires in the pipe radial direction can be restricted and each electric wire can be stably held.
Further, as described above, the end edges of the peripheral wall of the shield pipe and the two adjacent partition walls are inserted into the electric wire inserted one by one into the electric wire insertion space surrounded by the peripheral wall of the shield pipe and the two adjacent partition walls. By molding a resin material or rubber material interposed between the wire and the outer peripheral surface of the electric wire, each electric wire inserted into the electric wire insertion space contacts the peripheral wall of the shield pipe and the end edge of the partition wall.

By separating the wires in the shield pipe one by one, the wires in the shield pipe do not move in the radial direction of the pipe while interfering with each other, and each wire is partitioned in the shield pipe. By aligning them in parallel, the movement of the electric wires in the pipe radial direction can be restricted and each electric wire can be stably held.
Further, as described above, the end edges of the peripheral wall of the shield pipe and the two adjacent partition walls are inserted into the electric wire inserted one by one into the electric wire insertion space surrounded by the peripheral wall of the shield pipe and the two adjacent partition walls. By molding a resin material or rubber material interposed between the wire and the outer peripheral surface of the electric wire, each electric wire inserted into the electric wire insertion space contacts the peripheral wall of the shield pipe and the end edge of the partition wall.
