That is, "other vehicle types" refer to vehicles having different vehicle names, displacement, specifications, and destinations.
（ワイヤーハーネス１０Ａ）
　ワイヤーハーネス１０Ａは、図２，図１０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１０Ａは、複数の電線１１Ａが露出する程度にテープ２５Ａ（「第１結束部材」の一例）を巻き付けて仮巻き状態の電線束１１（図１０）を構成するとともに、仮巻き状態の電線束１１に更にテープ２５Ｂ（「第２結束部材」の一例）を電線１１Ａが露出しないように巻き付ける（本巻きする）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（結束部材）が用いられているが、異なる結束部材を用いることも可能である。 (Wire harness 10A)
As schematically shown in FIGS. 2 and 10, the wire harness 10A is a tape 25 (“tie-up member”) in which an adhesive is applied to one surface of the wire bundle 11 in which a plurality of wires 11A are bundled. An example is formed by winding (rolling). The wire harness 10A winds the tape 25A (an example of the "first binding member") to such an extent that the plurality of electric wires 11A are exposed to constitute the wire bundle 11 (Fig. 10) in a temporarily wound state. Further, a tape 25B (an example of a "second binding member") is wound around the wire bundle 11 so that the wire 11A is not exposed (the main winding is performed) (FIG. 2). Although the same tape 25 (binding member) is used as the tape 25A for temporary winding and the tape 25B for main winding, it is also possible to use different binding members.
　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 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 (inside a resin case (not shown) below the seat in the vehicle compartment).
　図１に示すように、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。 As shown in FIG. 1, the wire harness 10A is branched at a plurality of locations, and the first electric component 20 and the second electric component 23 are respectively connected to the ends of the branched electric wire 11A (wire harness). There is.
　電源１７とスイッチング素子１９，２８とは、図１１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.

In the present embodiment, two switching elements 28 are disposed side by side on the second surface 32 of the circuit board 30. The number of switching elements 28 provided in the switching unit 27 may be one, or three or more.
The switching element 28 is a semiconductor switching element formed of a MOSFET or the like, and performs energization or disconnection on the first electric component 20.
　コネクタハウジング３３は合成樹脂製であって、相手側の雄コネクタと嵌合する雌形の嵌合部３４を備える。嵌合部３４には肉薄の棒状をなす複数の金属製の端子２９Ａが貫通されている。端子２９Ａの一端側は嵌合部３４の内部に保持され、端子２９Ａの他端側は嵌合部３４を貫通してコネクタハウジング３３の後方に突出するとともに、回路基板３０に向けて略直角に曲げ加工されてスルーホールに挿通されている。端子２９Ａは、スルーホール内ではんだ付け等の公知の手法により、回路基板３０の導電路と電気的に接続されている。 The connector housing 33 is made of synthetic resin and includes a female fitting portion 34 that mates with a mating male connector. A plurality of thin, rod-like metal terminals 29A are penetrated through the fitting portion 34. One end side of the terminal 29A is held in the inside of the fitting portion 34, and the other end side of the terminal 29A penetrates the fitting portion 34 and protrudes rearward of the connector housing 33 and is substantially orthogonal to the circuit board 30. It is bent and inserted into the through hole. The terminal 29A is electrically connected to the conductive path of the circuit board 30 in the through hole by a known method such as soldering.
　嵌合部３４には、電線１１Ａの端末部に取付られた（接続された）雄コネクタが装着される。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コネクタや、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コネクタ等が装着される。
　なお、本実施形態では、嵌合部３４を雌形とし、相手側の雄コネクタと嵌合することとしたが、他の実施形態として、嵌合部を雄形とし、相手側の雌コネクタと嵌合するようにしてもよい。また、電線の端末部に取付けられた雄端子と雌端子のいずれか一方が嵌合部に収容されるようにしてもよい。 The male connector attached (connected) to the end of the electric wire 11A is attached to the fitting portion 34. Specifically, for example, a connector connected to the other end of the wire 11A whose one end is connected to the electrical components 20, 23 or to the other end of the wire 11A whose one end is connected to the manual switch 15 A connector or the like is attached.

　凹状面３９の曲率は、嵌め合わせる電線束１１の外形形状に応じて適宜設定することができる。例えば、電線１１Ａの本数や電線１１Ａの径が大きくなることで電線束１１の径が大きくなるほど凹状面３９の曲率を小さくすれば凹状面３９を電線束１１の外面に当接させた際に電線束１１の外面が凹状面３９の内側に嵌め入れられやすいため好ましい。 The concave surface 39 is recessed in an arc shape, and is formed to be inclined and deepened toward the middle side in the width direction in FIG. 3.
The curvature of the concave surface 39 can be appropriately set in accordance with the outer shape of the wire bundle 11 to be fitted. For example, when the curvature of the concave surface 39 is reduced as the diameter of the wire bundle 11 is increased by increasing the number of the wires 11A or the diameter of the wire 11A, the wire is used when the concave surface 39 is brought into contact with the outer surface of the wire bundle 11 It is preferable because the outer surface of the bundle 11 is easily fitted inside the concave surface 39.

You may go. When providing the locking mechanism, a known shape can be used, and for example, an elastic claw piece protruding from one side may be fitted and held in the other recess.

　次に、本発明の実施形態２について、図１２ないし図１６を参照しつつ説明する。実施形態２のスイッチングユニット４０は、実施形態１の半導体のスイッチング素子２８に代えてメカニカルリレー４１を搭載したものである。以下では、実施形態１と同一の構成については同一の符号を付して説明を省略する。 Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIGS. 12 to 16. The switching unit 40 of the second embodiment has a mechanical relay 41 mounted in place of the semiconductor switching element 28 of the first embodiment. In the following, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
　図１２に示すように、スイッチングユニット４０は、ケース５２にユニット本体４２が収容されている。 As shown in FIG. 12, in the switching unit 40, a unit main body 42 is accommodated in a case 52.

　メカニカルリレー４１は、コイルに電流を流して接点部を開閉するものであり、公知の形状のものを用いることができる。
　電子部品４４は、抵抗等の部品からなる。回路部４３は、バスバー端子５１が一体に形成されるとともに、メカニカルリレー４１及び電子部品４４の端子が挿通される複数のスルーホールが形成されている。
　バスバー端子５１は、嵌合部５０の奥壁に設けられた端子挿通孔５０Ｂに圧入されている。 As shown in FIG. 14, the unit body 42 has a circuit portion 43 on which the mechanical relay 41 and the electronic component 44 are mounted, a synthetic resin base 46 holding the circuit portion 43, and a hood to be fitted with the mating connector. And an interlocking portion 50.
The mechanical relay 41 flows a current through the coil to open and close the contact portion, and may have a known shape.
The electronic component 44 is made of a component such as a resistor. In the circuit portion 43, the bus bar terminals 51 are integrally formed, and a plurality of through holes into which the terminals of the mechanical relay 41 and the electronic component 44 are inserted are formed.
The bus bar terminal 51 is press-fit into a terminal insertion hole 50B provided in the back wall of the fitting portion 50.
　本実施形態においては、回路部４３には、２つのメカニカルリレー４１がユニット本体４２のケース５２への挿通方向に並んで配されている。なお、スイッチングユニット４０に備えられるメカニカルリレー４１は、１つでもよく、また、３つ以上の複数であってもよい。
　メカニカルリレー４１は、第１電装品２０に対して通電又は断電を実行する。 In the present embodiment, two mechanical relays 41 are arranged in the circuit portion 43 in the insertion direction of the unit main body 42 into the case 52. The number of mechanical relays 41 provided in the switching unit 40 may be one, or three or more.
The mechanical relay 41 performs energization or disconnection on the first electric component 20.
　基部４６は、箱形であって、例えば、モールド成形により、回路部４３のメカニカルリレー４１及び電子部品４４側を外部と仕切る仕切り壁４７が形成されている。メカニカルリレー４１及び電子部品４４が実装される面とは反対側の面には、図１５に示すように、メカニカルリレー４１及び電子部品４４の端子が挿通されるスルーホールに連なる位置に半田溜まり４９が凹設されている。 The base 46 has a box shape, and a partition wall 47 is formed by molding, for example, to divide the mechanical relay 41 and the electronic component 44 side of the circuit portion 43 from the outside.

For example, when the concave surface 55 is brought into contact with the outer surface of the wire bundle 11 by decreasing the curvature of the concave surface 55 as the diameter of the wire bundle 11 increases by increasing the number of the wires 11A and the diameter of each wire 11A. It is preferable because the outer surface of the wire bundle 11 can be easily fitted inside the concave surface 39.
　嵌合部５０は、回路部４３のバスバー端子５１側に組み付けられるものであり、嵌合部５０の外面には、図１２に示すように係止凸部５０Ａが設けられている。係止凸部５０Ａは、嵌合方向の一方側が段差状に突出し、他方側が傾斜状に突出し、段差状に突出する部分がケース５２の内面に形成された係止孔５２Ａの孔縁に係止してユニット本体４２のケース５２への抜け止めがなされている。
　実施形態２によれば、スイッチング素子は、比較的安価なメカニカルリレー４１であるため、ワイヤーハーネス１０Ａの製造コストを低減させることが可能になる。 The fitting portion 50 is assembled on the side of the bus bar terminal 51 of the circuit portion 43, and a locking convex portion 50A is provided on the outer surface of the fitting portion 50 as shown in FIG. In the locking projection 50A, one side in the fitting direction protrudes in a step-like shape, and the other side protrudes in an inclined manner, and the portion protruding in a step-like shape is locked at the hole edge of the locking hole 52A formed in the inner surface of the case 52 Thus, the unit main body 42 is prevented from coming off the case 52.
According to the second embodiment, since the switching element is a relatively inexpensive mechanical relay 41, the manufacturing cost of the wire harness 10A can be reduced.
