Description

ハーネスの取付構造Harness mounting structure
　本開示は、車両におけるハーネスの取付構造に関する。 The present disclosure relates to a harness mounting structure in a vehicle.
　自動車内の電気配線として、ワイヤーハーネス（以下、単にハーネスと呼ぶ）が用いられている。ハーネスは、電線部とコネクター部とを有する。電線部は、複数の電線が束ねられて構成されている。コネクター部は、電線部の両端に設けられている。コネクター部は、接続端子とそれを収容するハウジングとを有する。 A wire harness (hereinafter simply referred to as a harness) is used as electrical wiring in automobiles. The harness has an electric wire portion and a connector portion. The electric wire portion is configured by bundling a plurality of electric wires. The connector portions are provided at both ends of the electric wire portion. The connector section has connection terminals and a housing that accommodates them.
　コネクター部は、ハーネスの電気的接続部としての機能を有するとともに、ハーネスをシャーシに固定する固定部としての機能を有する。 The connector part has a function as an electrical connection part of the harness, and also has a function as a fixing part that fixes the harness to the chassis.
　ハーネスのコネクター部を利用したハーネスの取付構造としては、例えば特許文献１に記載されたものがある。 For example, Patent Document 1 describes a harness mounting structure that uses the connector portion of the harness.
特開２０１８－１１４７７６号公報JP 2018-114776 A
　ところで、自動車においては、多数のハーネスをシャーシの所定位置に配策する必要があるので、作業者の作業性を考慮すると、コネクター部のシャーシへの固定は簡易な作業で行うことができることが好ましい。 By the way, in an automobile, many harnesses need to be routed at predetermined positions on the chassis. Therefore, considering the workability of the operator, it is preferable that the fixing of the connector portion to the chassis can be performed by a simple operation. .
　そこで従来、コネクター部にクリップを設けるとともに、シャーシに貫通孔を設け、クリップを貫通孔に挿入することで、簡単にコネクター部をシャーシに取り付けることができる構成のものがある。 Therefore, conventionally, there is a configuration in which a clip is provided in the connector section, a through hole is provided in the chassis, and the clip is inserted into the through hole so that the connector section can be easily attached to the chassis.
　しかしながら、このような構成では、簡単にコネクター部をシャーシに取り付けることはできるが、コネクター部がシャーシに対して回転してしまうおそれがある。このコネクター部の回転を抑制するためには、クリップとシャーシの貫通孔との関係を、完全に回転を抑制するような複雑あるいは高精度のものとせざるを得なかった。 However, with such a configuration, although the connector part can be easily attached to the chassis, there is a risk that the connector part will rotate with respect to the chassis. In order to suppress the rotation of the connector portion, the relationship between the clip and the through-hole of the chassis had to be complicated or highly precise so as to completely suppress the rotation.
　例えば貫通孔を長孔とし、クリップを長孔に嵌まり込む扁平状のものとすることで、コネクター部の回転を抑制できる。しかし、長孔の形状の精度が低いと、回転を抑制できない、あるいは、コネクター部の向きが予定通りの向きにならない、あるいは、クリップを長孔に嵌め込む作業に手間がかかる、あるいは、クリップが長孔から外れてしまう、などの問題が生じる。 For example, by making the through hole an elongated hole and making the clip flat so as to fit into the elongated hole, the rotation of the connector can be suppressed. However, if the accuracy of the shape of the long hole is low, the rotation cannot be suppressed, or the direction of the connector portion will not turn as expected, or it will take time to fit the clip into the long hole, or the clip will not fit properly. Problems such as detachment from the long hole arise.
　本開示は、以上の点を考慮してなされたものであり、シャーシにクリップを取り付けるための構成を複雑あるいは高精度にしなくても、コネクター部の回転を抑制し得る、ハーネスの取付構造を提供する。 The present disclosure has been made in consideration of the above points, and provides a harness mounting structure capable of suppressing the rotation of the connector portion without complicating or increasing the precision of the configuration for mounting the clip to the chassis. do.

　以下、本開示の実施の形態を、図面を参照して説明する。 Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
　図１は、本開示の実施の形態に係るハーネスの取付構造の概略を示す斜視図である。 FIG. 1 is a perspective view showing an outline of a harness mounting structure according to an embodiment of the present disclosure.
　ハーネス１００は、電線部１１０と、電線部１１０の端部に設けられたコネクター部１２０と、を有する。 The harness 100 has a wire portion 110 and a connector portion 120 provided at the end of the wire portion 110 .
　電線部１１０は、複数の電線１１１が束ねられて構成されている。より具体的には、電線１１１がポリ塩化ビニルなどの被覆材料によって被覆され、さらに被覆後の電線がコルゲートチューブや樹脂テープなどの保護部材１１２によって束ねられている。 The electric wire portion 110 is configured by bundling a plurality of electric wires 111 . More specifically, the electric wire 111 is covered with a covering material such as polyvinyl chloride, and the covered electric wire is bundled with a protective member 112 such as a corrugated tube or resin tape.
　コネクター部１２０は、電線部１１０の一端に設けられている。電線部１１０の他端にはコネクター部１５０が設けられている。コネクター部１２０には、図２に示したように、他のハーネス１００′のコネクター部１２０′が挿し込まれる。これにより、ハーネス１００とハーネス１００′が電気的に接続される。また、コネクター部１５０は、車両の電装部品などに電気的に接続される。 The connector section 120 is provided at one end of the electric wire section 110 . A connector portion 150 is provided at the other end of the wire portion 110 . A connector portion 120' of another harness 100' is inserted into the connector portion 120, as shown in FIG. Thereby, the harness 100 and the harness 100' are electrically connected. Also, the connector portion 150 is electrically connected to an electrical component of the vehicle.
　コネクター部１２０は、接続端子（図示せず）とそれを収容するハウジング１２１とを有する。因みに、コネクター部１２０は、オス型の接続端子（図示せず）を有するオス型のコネクターである。 The connector part 120 has connection terminals (not shown) and a housing 121 that accommodates them. Incidentally, the connector part 120 is a male connector having male connection terminals (not shown).
　コネクター部１２０のハウジング１２１は、略直方体形状である。ハウジング１２１の第１の面１２１ａには、コネクター部１２０をシャーシ２００に取り付けるクリップ１３０が設けられている。図中の鎖線で模式的に示したシャーシ２００には、貫通孔（図示せず）が形成されており、この貫通孔にクリップ１３０を挿入して係合させることにより、シャーシ２００にコネクター部１２０を取り付けることができる。本実施の形態の貫通孔（図示せず）は例えば円形である。 A housing 121 of the connector section 120 has a substantially rectangular parallelepiped shape. A clip 130 for attaching the connector section 120 to the chassis 200 is provided on the first surface 121 a of the housing 121 . A through hole (not shown) is formed in the chassis 200 schematically indicated by the dashed line in the drawing, and the connector portion 120 is connected to the chassis 200 by inserting the clip 130 into the through hole and engaging it. can be installed. The through-hole (not shown) of this embodiment is circular, for example.
　かかる構成に加えて、電線部１１０は、ハウジング１２０からの導出位置から、コネクター部１２０（ハウジング１２１）が取り付けられるシャーシ２００の面に直交するハウジング１２１の第２の面１２１ｂに沿うように折り返されている。 In addition to this configuration, the electric wire portion 110 is folded back along the second surface 121b of the housing 121 orthogonal to the surface of the chassis 200 to which the connector portion 120 (housing 121) is attached from the lead-out position from the housing 120. ing.
　第２の面１２１ｂは、コネクター部１２０がクリップ１３０によってシャーシ２００に取り付けられた際に、クリップ１３０を回転中心として円周方向に回転する面である。本実施の形態では、電線部１１０に第２の面１２１ｂに沿った折り返し部分を設けることで、電線部１１０によって第２の面１２１ｂの前記円周方向の回転を規制する。 The second surface 121b is a surface that rotates in the circumferential direction around the clip 130 when the connector section 120 is attached to the chassis 200 by the clip 130 . In the present embodiment, the electric wire portion 110 is provided with a folded portion along the second surface 121b so that the electric wire portion 110 restricts the rotation of the second surface 121b in the circumferential direction.
　また、電線部１１０の折り返し部分は、バンド１４０によってハウジング１２１に固定されている。具体的には、バンド１４０は、ハウジング１２１の外面を周回するように形成されたくびれ部１２１ｃに沿ってハウジング１２１に巻回されている。これにより、バンド１４０がハウジング１２１から外れたりずれたりすることが抑制される。因みに、くびれ部１２１ｃは、作業者がコネクター部１２０の抜き挿し時にコネクター部１２０を指で把持し易くするためにハウジング１２１に形成されているものであり、本実施の形態では、これを有効活用してバンド１４０のずれを抑制するようになっている。なお、バンド１４０は、必ずしもくびれ部１２１ｃに沿って設けられる必要はない。 Also, the folded portion of the electric wire portion 110 is fixed to the housing 121 by a band 140 . Specifically, the band 140 is wound around the housing 121 along a constricted portion 121c formed around the outer surface of the housing 121 . This prevents the band 140 from coming off or shifting from the housing 121 . Incidentally, the constricted portion 121c is formed in the housing 121 so that the operator can easily grip the connector portion 120 with his/her fingers when inserting/removing the connector portion 120, and this embodiment effectively utilizes the constricted portion 121c. By doing so, the displacement of the band 140 is suppressed. Note that the band 140 does not necessarily need to be provided along the constricted portion 121c.
　次に、図２を用いて、本実施の形態の動作について説明する。 Next, the operation of this embodiment will be described using FIG.
　図２は、ハーネス１００をクリップ１３０（図１）によってシャーシ２００（図１）に取り付けた状態を、取り付け方向の正面から見た平面図である。なお、図２では、ハーネス１００のコネクター部１２０に、ハーネス１００′のコネクター部１２０′が接続されている。 FIG. 2 is a plan view of the harness 100 attached to the chassis 200 (FIG. 1) by the clip 130 (FIG. 1), viewed from the front in the attachment direction. 2, the connector portion 120 of the harness 100 is connected to the connector portion 120' of the harness 100'.
　ここで、コネクター部１２０は、クリップ１３０（図１）により回転自在にシャーシ２００に取り付けられている。 Here, the connector section 120 is rotatably attached to the chassis 200 by a clip 130 (Fig. 1).
　図２Ａに示したように、コネクター部１２０が時計方向に回転しようとすると、コネクター部１２０の下方部分が電線部１１０の折り返し部分に当接して回転が規制される。一方、図２Ｂに示したように、コネクター部１２０が反時計方向に回転しようとすると、コネクター部１２０の上方部分が電線部１１０の折り返し部分に当接して回転が規制される。 As shown in FIG. 2A, when the connector part 120 tries to rotate clockwise, the lower part of the connector part 120 comes into contact with the folded part of the electric wire part 110 and the rotation is restricted. On the other hand, as shown in FIG. 2B, when the connector portion 120 attempts to rotate counterclockwise, the upper portion of the connector portion 120 comes into contact with the folded portion of the electric wire portion 110 and the rotation is restricted.
　これにより、図１の矢印で示す方向へのコネクター部１２０の回転が抑制される。この結果、クリップ１３０とシャーシ２００の貫通孔との関係を、完全に回転を抑制するような複雑あるいは高精度のものとしなくても、電線部１１０の折り返し部分によって回転を抑制できるようになる。 As a result, rotation of the connector portion 120 in the direction indicated by the arrow in FIG. 1 is suppressed. As a result, even if the relationship between the clip 130 and the through-hole of the chassis 200 does not have to be complicated or highly accurate to completely suppress rotation, the folded portion of the electric wire portion 110 can suppress rotation.
　ところで、図３Ａに示したように、コネクター部１２０のハウジング１２１が回転してハウジング１２１の開口部が上を向いてしまうと、この開口部からハウジング１２１内に水などが進入し接続端子が腐食するおそれがあるので、好ましくない。 By the way, as shown in FIG. 3A, when the housing 121 of the connector section 120 rotates and the opening of the housing 121 faces upward, water or the like enters the housing 121 through this opening, corroding the connection terminals. It is not preferable because there is a risk of
　さらに言うと、図３Ｂに示したように、コネクター部１２０のハウジング１２１が回転中心（クリップ１３０）を中心として、ハウジング１２１の開口部が水平方向よりも上を向いてしまうと、この開口部からハウジング１２１内に水などが進入するおそれがあるので、好ましくない。 Furthermore, as shown in FIG. 3B, when the opening of the housing 121 of the connector section 120 faces upward from the horizontal direction around the rotation center (clip 130), the This is not preferable because water or the like may enter the housing 121 .
　本実施の形態のハーネス１００は、電線１１０にハウジング１２１の第２の面１２１ｂに沿うような折り返し部を設けるとともに、この折り返し部分をバンド１４０によってハウジング１２１に固定したことにより、コネクター部１２０を回転させるような外力が与えられたとしても、コネクター部１２０の回転が抑制される。 In the harness 100 of the present embodiment, the wire 110 is provided with a folded portion along the second surface 121b of the housing 121, and the folded portion is fixed to the housing 121 by the band 140, so that the connector portion 120 can be rotated. Rotation of the connector portion 120 is suppressed even if an external force is applied.
　例えば、図１に示したようにハーネス１００をシャーシ２００に取り付けた後に、図２に示したように、コネクター部１２０に、ハーネス１００′のコネクター部１２０′を接続する場合に、コネクター部１２０に回転力が付与されたとしてもコネクター部１２０の回転が電線部１１０の折り返し部分によって抑制される。 For example, after attaching the harness 100 to the chassis 200 as shown in FIG. Even if a rotational force is applied, the rotation of the connector portion 120 is suppressed by the folded portion of the electric wire portion 110 .
　このように、例えばハーネスの配策作業時にコネクター部１２０に不用意な力が与えられたとしても、コネクター部１２０の好ましくない方向への回転が未然に防止される。 In this manner, even if an unintentional force is applied to the connector portion 120 during a harness routing operation, the connector portion 120 is prevented from rotating in an undesirable direction.
　以上説明したように、本実施の形態によれば、電線部１１０は、ハウジング１２１からの導出位置から、コネクター部１２０が取り付けられるシャーシ２００の面に直交するハウジング１２１の第２の面１２１ｂに沿うように折り返されており、かつ、電線部１１０の折り返し部分は、バンド１４０によってハウジング１２１に固定されている。 As described above, according to the present embodiment, the wire portion 110 extends along the second surface 121b of the housing 121 perpendicular to the surface of the chassis 200 to which the connector portion 120 is attached from the lead-out position from the housing 121. and the folded portion of the wire portion 110 is fixed to the housing 121 by the band 140 .
　これにより、シャーシ２００にクリップ１３０を取り付けるための構成を複雑あるいは高精度にしなくても、コネクター部１２０の回転を抑制し得る、ハーネスの取付構造を実現できる。 As a result, a harness mounting structure capable of suppressing the rotation of the connector portion 120 can be realized without making the configuration for mounting the clip 130 to the chassis 200 complicated or highly precise.
　ここで、本実施の形態の構成によってコネクター部１２０の回転を確実に抑制するためには、電線部１１０の剛性が高い必要がある。本実施の形態の電線部１１０は、保護部材１１２内に複数の電線が束ねられて構成されているので、剛性が高く、コネクター部１２０の回転を抑制できる。 Here, in order to reliably suppress the rotation of the connector portion 120 with the configuration of the present embodiment, the wire portion 110 must have high rigidity. Since the electric wire portion 110 of the present embodiment is configured by bundling a plurality of electric wires in the protective member 112, the rigidity is high and the rotation of the connector portion 120 can be suppressed.
　さらに、上述の実施の形態の構成に加えて、電線部１１０を、電線部１１０の折り返し部から見てコネクター部１２０と反対側の位置において、固定具（図示せず）によってシャーシ２００に固定してもよい。つまり、図１の電線部１１０の折り返し部からコネクター部１５０との間の電線部１１０を固定具（図示せず）によってシャーシ２００に固定してもよい。このようにすれば、電線部１１０の変形や移動を抑制できるので、コネクター部１２０の回転をより確実に抑制できるようになる。 Furthermore, in addition to the configuration of the above-described embodiment, wire portion 110 is fixed to chassis 200 by a fixture (not shown) at a position on the opposite side of connector portion 120 when viewed from the folded portion of wire portion 110. may That is, the electric wire portion 110 between the folded portion of the electric wire portion 110 in FIG. 1 and the connector portion 150 may be fixed to the chassis 200 by a fixture (not shown). In this way, the deformation and movement of the wire portion 110 can be suppressed, so that the rotation of the connector portion 120 can be suppressed more reliably.
　図４及び図５は、本実施の形態に対する比較例の構成を示す図である。 4 and 5 are diagrams showing configurations of comparative examples for the present embodiment.
　図４では、コネクター部１２０とコネクター部１２０′とを接続することで、ハーネス１００とハーネス１００′が接続されている。コネクター部１２０は、シャーシ２００に回転自在に取り付けられている。ハーネス１００′の電線部１１０′は、固定具３００によってシャーシ２００に固定されている。これにより、コネクター部１２０の回転が抑制される。 In FIG. 4, the harness 100 and the harness 100' are connected by connecting the connector portion 120 and the connector portion 120'. Connector section 120 is rotatably attached to chassis 200 . Wire portion 110 ′ of harness 100 ′ is fixed to chassis 200 by fixture 300 . Thereby, the rotation of the connector portion 120 is suppressed.
　図４の比較例のメリットは、構成が簡単であることである。しかしながら、図４の比較例では、次のデメリットがある。第１に、相手側のハーネス１００′を含め、広いスペースが必要となる。また、第２に、ハーネス１００′の長さの誤差が大きいと、意図した回転制御ができない可能性がある。第３に、他のハーネス１００′のレイアウトに依存する。 The advantage of the comparative example in FIG. 4 is that the configuration is simple. However, the comparative example of FIG. 4 has the following disadvantages. First, a large space is required including the mating harness 100'. Secondly, if the error in the length of the harness 100' is large, there is a possibility that the intended rotation control cannot be performed. Third, it depends on the layout of other harnesses 100'.
　図５の例は、上述した「発明が解決しようとする課題」の項でも説明したような、シャーシ２００に長孔（図示せず）を形成するとともに、クリップ１３０を長孔に嵌まり込む扁平状のものとした例である。 In the example of FIG. 5, a long hole (not shown) is formed in the chassis 200, and the clip 130 is fitted into the long hole, as described in the above "Problem to be Solved by the Invention" section. This is an example of a shape.
　図５の比較例のメリットは、実施の形態と同様に相手側のハーネス１００′に依存せずにコネクター部１２０の回転を抑制できることである。しかしながら、上述したように、長孔の形状の精度が低いと、回転を抑制できない、あるいは、コネクター部の向きが予定通りの向きにならない、あるいは、クリップを長孔に嵌め込む作業に手間がかかる、あるいは、クリップが長孔から外れてしまう、などの問題が生じる。 The advantage of the comparative example of FIG. 5 is that it is possible to suppress the rotation of the connector portion 120 without depending on the mating harness 100', as in the embodiment. However, as described above, if the accuracy of the shape of the long hole is low, the rotation cannot be suppressed, or the orientation of the connector portion is not as expected, or it takes time and effort to fit the clip into the long hole. Alternatively, problems such as the clip coming off the long hole may occur.
　上述の実施の形態は、本発明を実施するにあたっての具体化の一例を示したものに過ぎず、これらによって本発明の技術的範囲が限定的に解釈されてはならないものである。すなわち、本発明はその要旨、またはその主要な特徴から逸脱することの無い範囲で、様々な形で実施することができる。 The above-described embodiment merely shows an example of implementation of the present invention, and the technical scope of the present invention should not be construed to be limited by these. That is, the present invention can be embodied in various forms without departing from its spirit or essential characteristics.
　上述の実施の形態では、オス型のコネクター部１２０にクリップ１３０、折り返し部、バンド１４０を設けた場合について述べたが、本発明はこれに限らず、メス型のコネクター部にクリップ、折り返し部、バンドを設けてメス型のコネクター部の回転を抑制するようにしてもよい。 In the above-described embodiment, the male connector portion 120 is provided with the clip 130, the folded portion, and the band 140. However, the present invention is not limited to this, and the female connector portion is provided with the clip, folded portion, and A band may be provided to restrain rotation of the female connector portion.
