特開２００７－１８６０８２号公報JP 2007-186082 A
　近年、車両の高性能化に伴って電装品の個数が増大する傾向がある。すると、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。また、電装品に接続されるワイヤーハーネスも大型化する。このため、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空間を車両内に確保する必要が生じていた。 In recent years, the number of electrical components tends to increase as the performance of vehicles increases. Then, the number of switching elements for performing energization or disconnection of the electrical component also increases. In addition, the wire harness connected to the electrical components is also upsized. Therefore, it has been necessary to secure a space for accommodating the switching element and the wire harness in the vehicle.
　しかし、居住空間の大型化に伴い、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いる。このため、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, with the enlargement of living space, it has become difficult to secure a space for mounting a switching element or a wire harness in a vehicle. For this reason, miniaturization of a wire harness system including a switching element and a wire harness has been required.
　本発明は上記のような事情に基づいて完成されたものであって、小型化されたワイヤーハーネスシステムを提供することを目的とする。 The present invention has been completed based on the above circumstances, and it is an object of the present invention to provide a miniaturized wire harness system.
　本発明は、車両に搭載されるワイヤーハーネスシステムであって、複数の電線からなる電線束を有するワイヤーハーネスと、前記電線に接続された第１電装品と、前記第１電装品に対して通電又は断電を実行するスイッチング素子を有し、前記電線束から分岐された電線に接続されたスイッチングユニットと、を備え、前記スイッチングユニットは車両に取付けられているところに特徴を有する。 The present invention is a wire harness system mounted on a vehicle, comprising: a wire harness having a wire bundle made of a plurality of wires; a first electrical component connected to the wires; and energization of the first electrical component. Or a switching unit having a switching element for performing power disconnection and connected to a wire branched from the wire bundle, wherein the switching unit is characterized in that it is mounted on a vehicle.
　本構成によれば、電線束から分岐された電線に接続されたスイッチングユニットは、車両に取付けられているため、電装品の位置に応じてスイッチング素子を分散して配置することが可能になる。そのため、例えば多数のスイッチング素子を一箇所に集中して配置する場合と比較して、全ての電線を一箇所に集める必要がなくなり、ワイヤーハーネスシステムを構成する電線の使用量（長さ）を少なくする（短くする）ことが可能になる。よって、ワイヤーハーネスシステムを小型化することが可能になる。 According to this configuration, since the switching unit connected to the wire branched from the wire bundle is attached to the vehicle, the switching elements can be dispersedly arranged according to the position of the electrical component. Therefore, compared to, for example, arranging a large number of switching elements in one place, it is not necessary to collect all the electric wires in one place, and the amount of use (length) of electric wires constituting the wire harness system is reduced. It is possible to do (shorten). Thus, the wire harness system can be miniaturized.
　また、スイッチングユニットを車両に取付けることで、電線の熱や振動による影響をスイッチングユニットが受けることを抑制することが可能になる。 Further, by attaching the switching unit to a vehicle, it is possible to suppress the switching unit from being affected by the heat and vibration of the electric wire.

The individual electrical components include: electrical components used only for vehicles of different names, electrical components used only for vehicles with different displacements, electrical components used only for vehicles of different specifications, and vehicles of different destinations Including electrical components used only in
　本実施形態では、第１電装品２０は、図１に示すように、シートヒータ２１及び後部座席用ルームライト２２とされている。なお、第１電装品２０を、例えば、ディアイサ、ＤＲＬシステム、フォグランプ、ホーン、ＰＴＣヒータ等としてもよい。 In the present embodiment, as shown in FIG. 1, the first electric component 20 is a seat heater 21 and a room light 22 for the rear seat. The first electric component 20 may be, for example, a de-charger, a DRL system, a fog lamp, a horn, a PTC heater, or the like.
　シートヒータ２１は、搭乗者が搭乗する車室１３に取付けられたシート１６に埋め込まれている。また、後部座席用ルームライト２２は、車室１３内の後部座席の天井部寄りの位置に配設されている。 The seat heater 21 is embedded in a seat 16 attached to a passenger compartment 13 in which a passenger boardes. Further, the rear seat room light 22 is disposed at a position near the ceiling of the rear seat in the passenger compartment 13.
　第２電装品２３は、他車種においても使用される共通電装品とされ、本実施形態ではテールライト２４とされているが、これに限らず、例えば、ワイパモータ、ヘッドライト、ルームライト、セルモータ、ウォッシャポンプ、リアウィンドウ用デフロスタ等とすることも可能である。第２電装品２３は、電気接続箱１８のスイッチング素子１９により通電又は断電が実行される。 The second electric component 23 is a common electric component used also in other vehicle types, and is a taillight 24 in this embodiment, but not limited to this, for example, a wiper motor, a headlight, a room light, a cell motor, It is also possible to use a washer pump, a rear window defroster or the like. The second electric component 23 is energized or de-energized by the switching element 19 of the electric connection box 18.
　「車種」とは、車名の差異、排気量の差異、仕様の差異、及び仕向け地の差異を含む。詳細に説明すると、他車種とは、例えば、車名が異なる場合、車名は同じであるが排気量が異なる場合、車名も排気量も同じであるが仕様が異なる場合、車名も排気量も仕様も同じであるが、仕向け地が異なる場合等を含む。すなわち、「他車種」とは、車名、排気量、仕様、及び仕向け地の少なくとも一つが異なる車両１２をいう。
（ワイヤーハーネス１０Ａ）
　ワイヤーハーネス１０Ａ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１０Ａは、車両１２の床下（車室内におけるシートよりも下側）を通るように配索されている。 "Model" includes car name differences, engine displacement differences, specification differences, and destination differences. More specifically, for example, when the vehicle name is different, the vehicle name is the same but the displacement is different. When the vehicle name and the displacement are the same but the specification is different, the vehicle name is also emission. Although the amount and specifications are the same, this includes cases where the destinations are different. That is, "other vehicle type" refers to a vehicle 12 in which at least one of the vehicle name, the displacement, the specifications, and the destination is different.
(Wire harness 10A)
The wire harness 10A 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 10A is routed so as to pass under the floor of the vehicle 12 (below the seat in the passenger compartment).
　ワイヤーハーネス１０Ａは複数箇所で分岐されており、この分岐されたワイヤーハーネス１０Ａを構成する複数の電線１１Ａ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 10A 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 plurality of electric wires 11A constituting the branched wire harness 10A.
　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.
　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、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から直接行われる。
　これにより、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１０Ａ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１０Ａ間の距離が短い）スイッチングユニット２７のスイッチング素子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 disposed on the instrument panel 14 without passing through the electrical connection box 18.
Thus, when the manual switch 15 instructs the energization or de-energization of the first electric component 20, the signal from the manual switch 15 does not pass through the electric connection box 18 (the distance between the wire harnesses 10A is long). It is given directly to the switching element 28 of the switching unit 27 (the distance between the wire harnesses 10A is short), and turns the switching element 28 on and off.
　電源１７とスイッチング素子１９，２８とは、図１５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.
　ワイヤーハーネス１０Ａは、図２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１１に対して一方の面に粘着剤又は接着剤が塗布されたテープ２５を電線束１１が隠れる程度に捲回させる（巻き付ける）ことによって形成される。 As schematically shown in FIG. 2, the wire harness 10 </ b> A hides the tape 25 having the adhesive or the adhesive applied to one surface of the wire bundle 11 in which the plurality of electric wires 11 </ b> A are bundled. It is formed by winding to a degree.
　電線束１１を構成する複数の電線１１Ａのうち、スイッチング素子２８を備えるスイッチングユニット２７が接続された電線１１Ａが電線束１１から分岐しており、この分岐された電線１１Ａの端末部に接続されたスイッチングユニット２７には、テープ２５が巻き付けられておらず、ワイヤーハーネス１０Ａの外部（電線束１１の外部）に導出されて車両１２に取付けられている。 Of the plurality of wires 11A constituting the wire bundle 11, the wire 11A to which the switching unit 27 having the switching element 28 is connected is branched from the wire bundle 11, and is connected to the end of the branched wire 11A. The tape 25 is not wound around the switching unit 27 and is led out of the wire harness 10A (outside of the wire bundle 11) and attached to the vehicle 12.
（スイッチングユニット２７）
　スイッチングユニット２７は、ワイヤーハーネス１０Ａが配策される経路上の複数の位置に配されており、図７に示すように、ユニット本体２９が合成樹脂製のケース３６に収容されている。

The circuit board 30A includes a first surface 31 to which the connector housing 33 is attached, and a second surface 32 which is a back surface to the first surface 31 and on which the switching element 28 is mounted.
　回路基板３０Ａの第２面３２には、スイッチング素子２８が回路基板３０Ａに形成された導電路にはんだ付け等の公知の手法により電気的に接続されている。本実施形態においては、回路基板３０Ａの第２面３２には、２つのスイッチング素子２８が横並びに配設されている。なお、スイッチングユニット２７に備えられるスイッチング素子２８は、１つでもよく、また、３つ以上の複数であってもよい。 The switching element 28 is electrically connected to the conductive path formed on the circuit board 30A on the second surface 32 of the circuit board 30A by a known method such as soldering. In the present embodiment, two switching elements 28 are disposed side by side on the second surface 32 of the circuit board 30A. The number of switching elements 28 provided in the switching unit 27 may be one, or three or more.
　スイッチング素子２８は、例えばＭＯＳＦＥＴからなる半導体スイッチング素子であって、第１電装品２０に対して通電又は断電を実行する。
　コネクタハウジング３３は合成樹脂製であって、電線１１Ａの端末に接続された複数の端子（図示しない）が装着される装着部３４を備える。装着部３４は、端子が嵌め入れられる複数の凹部３４Ａが並んで形成されている。 The switching element 28 is a semiconductor switching element formed of, for example, a MOSFET, and performs energization or disconnection on the first electric component 20.
The connector housing 33 is made of synthetic resin, and includes a mounting portion 34 to which a plurality of terminals (not shown) connected to the end of the electric wire 11A are mounted. The mounting portion 34 is formed with a plurality of concave portions 34A in which the terminals are fitted.
　複数の凹部３４Ａには、電線１１Ａの端末部に取付られた（接続された）金属製の雌端子が嵌め入れられる。具体的には、例えば、一端側が電装品２０，２３に接続された電線１１Ａの他端側に接続された端子や、一端側が手動スイッチ１５に接続された電線１１Ａの他端側に接続された端子等が嵌め入れられる。凹部３４Ａに嵌め入れられた端子は、凹部３４Ａの内部のランスからなる抜け止め機構３４Ｂに係止されて端子の抜けが防止される。 The metal female terminals attached (connected) to the end portions of the wires 11A are fitted into the plurality of recesses 34A.
