Description

ワイヤーハーネスシステムWire harness system
 本発明は、複数の電線を備えたワイヤーハーネスシステムに関する。 The present invention relates to a wire harness system provided with a plurality of electric wires.
 従来、車両には複数の電装品が搭載されており、これらの電装品は、ワイヤーハーネスを介して電源と接続されている。このワイヤーハーネスの一例として特許文献1に記載のものは、車両に搭載されたスイッチング素子によって電装品への通電又は断電が実行されるようになっている。 Conventionally, a plurality of electrical components are mounted on a vehicle, and these electrical components are connected to a power source via a wire harness.

 近年、車両の高性能化に伴って電装品の個数が増大し、電装品の通電又は断電を実行するスイッチング素子の個数も増大する傾向がある。この場合、電装品に接続されるワイヤーハーネスも大型化するため、スイッチング素子やワイヤーハーネスを収容するための広い空間を車両内に確保する必要がある。 In recent years, as the performance of vehicles increases, the number of electrical components increases, and the number of switching elements for performing energization or disconnection of the electrical components also tends to increase. In this case, in order to increase the size of the wire harness connected to the electrical component, it is necessary to secure a large space for accommodating the switching element and the wire harness in the vehicle.
 しかし、居住空間の大型化の要請に伴い、車両内においてスイッチング素子やワイヤーハーネスを搭載するためのスペースを確保することは困難になっており、スイッチング素子及びワイヤーハーネスを含むワイヤーハーネスシステムの小型化が求められていた。 However, it has become difficult to secure a space for mounting a switching element and a wire harness in a vehicle with the demand for enlargement of a living space, and downsizing of a wire harness system including the switching element and the wire harness Was required.

(ワイヤーハーネス11)
 ワイヤーハーネス11は、図2,図12に模式的に示すように、複数の電線11Aが束ねられた電線束に対して一方の面に粘着剤が塗布されたテープ25(「結束部材」の一例)を捲回させる(巻き付ける)ことによって形成される。このワイヤーハーネス11は、複数の電線11Aが露出する程度にテープ25Aを巻き付けて仮巻き状態の電線束(図12)を構成するとともに、仮巻き状態の電線束に更にテープ25Bを電線11Aが露出しないように本巻きした構成となっている(図2)。なお、仮巻きする際のテープ25Aと本巻きする際のテープ25Bは、同一のテープ25が用いられているが、異なるテープを用いることも可能である。
(Wire harness 11)
The wire harness 11 is, as schematically shown in FIGS. 2 and 12, a tape 25 (an example of a “binding member” in which an adhesive is applied to one surface of a wire bundle in which a plurality of wires 11A are bundled. Formed by winding (rolling). The wire harness 11 winds the tape 25A to such an extent that the plurality of electric wires 11A are exposed to constitute a wire bundle in a temporarily wound state (FIG. 12), and further exposes the wire 25A to the wire bundle in the temporarily wound state. In order not to do this, it has become the constitution which is wound (figure 2). Although the same tape 25 is used as the tape 25A at the time of temporary winding and the tape 25B at the time of main winding, it is also possible to use different tapes.
 電線11Aは、芯線(図示せず)の外周を、合成樹脂製の絶縁層で被覆してなる。芯線は、金属、カーボンナノチューブ等の導電性の材料からなる。本実施形態においては、金属細線を撚り合わせてなる撚り線が用いられている。撚り線に用いられる金属としては、銅、銅合金、アルミニウム、アルミニウム合金、鉄、鉄合金等、必要に応じて任意の金属を適宜に選択できる。本実施形態では芯線は、銅又は銅合金が用いられる。 The electric wire 11A is formed by covering the outer periphery of a core wire (not shown) with an insulating layer made of synthetic resin. The core wire is made of a conductive material such as metal or carbon nanotube. In the present embodiment, a stranded wire formed by twisting metal fine wires is used. As a metal used for a strand wire, arbitrary metals can be suitably selected as needed, such as copper, a copper alloy, aluminum, an aluminum alloy, iron, an iron alloy. In the present embodiment, copper or a copper alloy is used as the core wire.
 ワイヤーハーネス11は、車両12の床下、ピラー内等、必要に応じて任意の位置に配索されるものである。本実施形態においては、ワイヤーハーネス11は、車両12の床下(車室内におけるシートよりも下側の図示しない樹脂ケースの内側)を通るように配索されている。 The wire harness 11 is arranged at an arbitrary position as needed, such as under the floor of the vehicle 12 or in a pillar. In the present embodiment, the wire harness 11 is routed so as to pass under the floor of the vehicle 12 (inside the resin case (not shown) below the seat in the vehicle compartment).
 このワイヤーハーネス11は複数箇所で分岐されており、この分岐された電線11A(ワイヤーハーネス)の端末には、第1電装品20及び第2電装品23がそれぞれ接続されている。 The wire harness 11 is branched at a plurality of places, and the first electric component 20 and the second electric component 23 are respectively connected to the terminals of the branched electric wire 11A (wire harness).
 電源17とスイッチング素子19,28とは、図13に示すように、ヒューズ26を介して電気的に接続されている。このヒューズ26は、金属導体により形成されたヒューズでもよく、また、電気回路によって実現された過電流保護機能による過電流遮断装置であってもよく、また、スイッチング素子を制御するプログラムによって実現された過電流保護機能であってもよい。 The power supply 17 and the switching elements 19 and 28 are electrically connected via a fuse 26 as shown in FIG. The fuse 26 may be a fuse formed of a metal conductor, or may be an overcurrent interrupting device with an overcurrent protection function implemented by an electric circuit, and may be implemented by a program for controlling a switching element. It may be an over current protection function.
 第1電装品20の通電又は断電を行うスイッチング素子28のオンオフの信号は、電気接続箱18を通らず、手動スイッチ15から直接行われる。
 これにより、インスツルメントパネル14に配設された手動スイッチ15によって第1電装品20の通電又は断電が指示されると、手動スイッチ15からの信号は、(ワイヤーハーネス間の距離が長い)電気接続箱18を経由せずに(ワイヤーハーネス間の距離が短い)スイッチング素子28に直接的に与えられ、スイッチング素子28をオンオフする。
The on / off signal of the switching element 28 for energizing or de-energizing the first electric component 20 is directly transmitted from the manual switch 15 without passing through the electric connection box 18.
Thus, when the manual switch 15 disposed on the instrument panel 14 instructs the energization or de-energization of the first electric component 20, the signal from the manual switch 15 indicates that the distance between the wire harnesses is long. It is directly given to the switching element 28 without passing through the electrical connection box 18 (the distance between the wire harnesses is short), and turns the switching element 28 on and off.
