- the end portion on the vehicle body 105 side (relay box 106 side) is referred to as “other end portion”.
- a wheel-side power connector 11a for connection to the EPB electric motor 101a is attached to one end of the pair of first electric wires 2, and a relay box 106 is attached to the other end of the pair of first electric wires 2.
- a vehicle body side power connector 11b for connection to the electric wire group 107 is attached.
- An ABS sensor 104a is attached to one end of the pair of second electric wires 3 (paired stranded wire 4), and the other end of the pair of second electric wires 3 (paired stranded wire 4) is connected to the relay box 106.
- a vehicle body side ABS connector 12 for connection to the electric wire group 107 is attached.
- the composite cable 1 according to the present embodiment includes the tape member 6 spirally wound around the assembly 5, and the twist direction of the paired strand 4 and the twist direction of the assembly 5. And the twisting direction of the assembly 5 and the winding direction of the tape member 6 are different.
- the friction between the electric wires 2, 3 and the sheath 7 can be reduced without using a lubricant such as talc powder, the stress applied to the electric wires 2, 3 during bending can be reduced, and bending resistance can be achieved. It becomes possible to improve the property. Since the tape member 6 can be easily removed at the time of terminal processing, it becomes possible to improve workability of terminal processing while maintaining bending durability.
- the twisting direction of the twisted wire 4 and the winding direction of the tape member 6 are made different by making the twisting direction of the twisted pair wire 4 different from the twisting direction of the assembly 5 and making the twisting direction of the assembly 5 different from the winding direction of the tape member 6. It is possible to suppress the bending wrinkles due to, and stabilize the twist pitches P1 and P2 of the twisted pair wire 4 and the assembly 5. As a result, it is possible to suppress the variation in the bending characteristics, and it is possible to realize the composite cable 1 in which flexibility in the longitudinal direction is stable and easy to route. Furthermore, since the cross-sectional shape of the composite cable 1 can be made closer to a circular shape, the strip operation of the sheath 7 becomes easy.
- a pair of twisted wires (4) obtained by twisting a pair of first electric wires (2) and a pair of second electric wires (3) having an outer diameter smaller than that of the first electric wires (2);
- a tape member (6) spirally wound around an assembly (5) in which a pair of first electric wires (2) and the twisted pair wire (4) are twisted together, and the twisted pair wire

Abstract
Description
以下、本発明の実施の形態を添付図面にしたがって説明する。
図1は、本実施の形態に係る複合ケーブルを用いた車両の構成を示すブロック図である。
図2Aは、本実施の形態に係る複合ケーブル1の横断面図、図2Bは第1電線と第2電線の撚り方向およびテープ部材の巻方向を説明する図である。
本実施の形態に係る複合ケーブル1では、対撚線4の撚り方向と集合体5の撚り方向とが異なり、かつ、集合体5の撚り方向とテープ部材6の巻き付け方向とが異なっている。つまり、複合ケーブル1では、対撚線4の撚り方向とテープ部材6の巻き付け方向とは同じ方向となり、集合体5の撚り方向のみが異なる方向となっている。
図3は、本実施の形態に係る複合ハーネスの概略構成図である。
以上説明したように、本実施の形態に係る複合ケーブル1では、集合体5の周囲に螺旋状に巻き付けられたテープ部材6を備え、対撚線4の撚り方向と集合体5の撚り方向とが異なり、かつ、集合体5の撚り方向とテープ部材6の巻き付け方向とが異なっている。
次に、以上説明した実施の形態から把握される技術思想について、実施の形態における符号等を援用して記載する。ただし、以下の記載における各符号等は、特許請求の範囲における構成要素を実施の形態に具体的に示した部材等に限定するものではない。
2…第1電線
3…第2電線
