Description

本発明は、ワイヤハーネスに関する。 The present invention relates to a wire harness.

ハイブリッド車や電気自動車に搭載される車両用導電路（ワイヤハーネス）として、シールド機能を備えたものがある（例えば、特許文献１参照。）。この車両用導電路は、複数本の電線を一括して包囲する筒状のシールド手段を有し、シールド手段として金属製のパイプが使用される。このようなパイプを用いたシールド機能付ワイヤハーネスでは、電線で発生した熱がパイプの内部にこもりやすい。そのため、放熱効率の向上を図るため、電線に沿って冷却パイプを配置する技術や電線を冷却する装置が提案されている（特許文献２〜４参照。）。 Some conductive paths (wire harnesses) for vehicles mounted on hybrid vehicles and electric vehicles have a shielding function (see, for example, Patent Document 1). This vehicle conductive path has a tubular shielding means that collectively surrounds a plurality of electric wires, and a metal pipe is used as the shielding means. In a wire harness with a shield function using such a pipe, the heat generated by the electric wire tends to be trapped inside the pipe. Therefore, in order to improve the heat dissipation efficiency, a technique of arranging a cooling pipe along the electric wire and a device for cooling the electric wire have been proposed (see Patent Documents 2 to 4).

シールド機能付ワイヤハーネス、特に、バッテリとパワーコントロールユニット（ＰＣＵ）との間に配索される高圧ワイヤハーネスにおいては、年々、通電電流が増加し、電線が太くなる傾向にある。このため、その電線を包囲する金属パイプも大径化し、ワイヤハーネスを車両に搭載するためのスペースが肥大化することとなる。このようなワイヤハーネスに特許文献２〜４に記載の冷却パイプや冷却装置を組み合わせると、一段とスペースが肥大化する。 In a wire harness with a shielding function, particularly in a high-voltage wire harness distributed between a battery and a power control unit (PCU), the energizing current tends to increase year by year and the electric wire tends to become thicker. Therefore, the diameter of the metal pipe surrounding the electric wire is also increased, and the space for mounting the wire harness on the vehicle is increased. When the cooling pipes and cooling devices described in Patent Documents 2 to 4 are combined with such a wire harness, the space is further enlarged.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、省スペースで車両に搭載できるワイヤハーネスを提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wire harness that can be mounted on a vehicle in a space-saving manner.

以上、本発明について簡潔に説明した。更に、以下に説明される発明を実施するための形態（以下、「実施形態」という。）を添付の図面を参照して通読することにより、本発明の詳細は更に明確化されるであろう。 The present invention has been briefly described above. Further, the details of the present invention will be further clarified by reading through the embodiments described below (hereinafter referred to as "embodiments") with reference to the accompanying drawings. ..

本発明に関する具体的な実施形態について、各図を参照しながら以下に説明する。 Specific embodiments of the present invention will be described below with reference to the respective figures.

図１は、本発明の一実施形態の概略図である。本実施形態では、シールド機能付高圧ワイヤハーネス（以下単にワイヤハーネスと称する。）１０がパワーコントロールユニット（ＰＣＵ）２０とバッテリ（ＢＡＴＴ）３０との間に配索される例を示す。ワイヤハーネス１０は、三本の電線１２（図３参照）と、三本の電線１２が内部に挿通された金属パイプ１（第一パイプ）と、金属パイプ１の外周を覆う金属パイプ２（第二パイプ）と、を備える。また、ワイヤハーネス１０は、金属パイプ１と金属パイプ２との間に冷却水を流すための空洞３を有する。すなわち、ワイヤハーネス１０において、複数の電線１２を二重の金属パイプ１，２が包囲している。二重の金属パイプ１，２の間に設けられた空洞３は、冷却水１３（図２参照）が流れる水路となっている。金属パイプ２の長手方向の両端には、それぞれ孔２１が設けられ、孔２１には空洞３に冷却水１３を送り込むためのチューブ４，５が連結される。チューブ４はＰＣＵ２０に連結され、チューブ５はＢＡＴＴ３０に連結される。これにより、ＰＣＵ２０、ＢＡＴＴ３０用の冷却水を電線１２の冷却用として用いることができる。 FIG. 1 is a schematic view of an embodiment of the present invention. In this embodiment, an example is shown in which a high-voltage wire harness with a shielding function (hereinafter, simply referred to as a wire harness) 10 is arranged between the power control unit (PCU) 20 and the battery (BATT) 30. The wire harness 10 includes three electric wires 12 (see FIG. 3), a metal pipe 1 (first pipe) through which the three electric wires 12 are inserted, and a metal pipe 2 (first pipe) that covers the outer periphery of the metal pipe 1. Two pipes) and. Further, the wire harness 10 has a cavity 3 for flowing cooling water between the metal pipe 1 and the metal pipe 2. That is, in the wire harness 10, the plurality of electric wires 12 are surrounded by the double metal pipes 1 and 2. The cavity 3 provided between the double metal pipes 1 and 2 is a water channel through which the cooling water 13 (see FIG. 2) flows. Holes 21 are provided at both ends of the metal pipe 2 in the longitudinal direction, and tubes 4 and 5 for feeding the cooling water 13 into the cavity 3 are connected to the holes 21. The tube 4 is connected to the PCU 20, and the tube 5 is connected to the BATT 30. As a result, the cooling water for the PCU 20 and BATT 30 can be used for cooling the electric wire 12.

図２は、図１のＡ−Ａ断面図である。図２に示すように、金属パイプ１の内部には三本の電線１２が挿通されており、金属パイプ１の内周面は互いに外接する三本の電線１２に外接している。金属パイプ２は金属パイプ１を同心円状に覆い、金属パイプ１と金属パイプ２との間に設けた空洞３には、冷却水１３が満たされている。 FIG. 2 is a cross-sectional view taken along the line AA of FIG. As shown in FIG. 2, three electric wires 12 are inserted inside the metal pipe 1, and the inner peripheral surfaces of the metal pipe 1 are circumscribed by the three electric wires 12 circumscribing each other. The metal pipe 2 covers the metal pipe 1 concentrically, and the cavity 3 provided between the metal pipe 1 and the metal pipe 2 is filled with cooling water 13.

図３は、冷却前における図１のＢ部分の拡大断面図であり、図４は、冷却時における図１のＢ部分の拡大断面図である。但し、理解を容易にするため、電線１２は斜視図とした。金属パイプ１，２の長手方向の一端は図３及び図４に示すようにＢＡＴＴ３０に接続され、他端は同様にＰＣＵ２０に接続される。金属パイプ１，２の端部は、導電性の金属細線をメッシュ状に編み込んだ編組部材６に包囲され、編組部材６と金属パイプ２とが金属バンド７によって接続されている。さらに、金属バンド７で接続された編組部材６と金属パイプ２とを、外装８で保護した上で、結束バンド９で固定している。金属パイプ１，２の端部において、金属パイプ２が金属パイプ１と接続して端面を構成することにより、冷却水１３を空洞３内に保持している。また、金属パイプ２の端部において、孔２１にチューブ５が連結され、ＢＡＴＴ３０からの冷却水１３が孔２１を介してチューブ５から空洞３に送り込まれる。金属パイプ１，２の他端においては、孔２１を介してチューブ４が連結され、ＰＣＵ２０からの冷却水１３が孔２１を介してチューブ４から送り込まれる。そして、図４に示すように、空洞３内が冷却水１３で満たされる。その後、空洞３内の冷却水１３は、チューブ４，５を介して、ＰＣＵ２０、ＢＡＴＴ３０内に備わった冷却機構（図示せず）に流れ込み、冷却される。すなわち、電線１２で発生した熱は、電線１２と金属パイプ１とが接する箇所から金属パイプ１に効率よく伝達され、金属パイプ１が冷却水１３によって冷却される。金属パイプ２の長手方向両端から空洞３に冷却水１３を送りこむことにより、電線１２を長手方向に沿って均一に冷却できる。このように、シールド機能を有する金属パイプ１，２内の空洞３に冷却水１３を流すことで、発熱した電線１２を効率よく冷却できる。電線に大電流を流すと発熱するため、電線を太くして電線の過熱を防止する必要があるが、本実施形態によれば、電線１２を冷却して発熱を抑制できるため、電線１２を太くする必要がなくなり、電線のサイズダウンが可能となる。なお、冷却水１３をチューブ５から空洞３に送り込みチューブ４から排出してもよい。この場合、例えばＰＣＵ２０からＢＡＴＴ３０への不図示の流路により冷却水１３を戻す。 FIG. 3 is an enlarged cross-sectional view of the portion B of FIG. 1 before cooling, and FIG. 4 is an enlarged cross-sectional view of the portion B of FIG. 1 during cooling. However, in order to facilitate understanding, the electric wire 12 is a perspective view. One end of the metal pipes 1 and 2 in the longitudinal direction is connected to the BATT 30 as shown in FIGS. 3 and 4, and the other end is similarly connected to the PCU 20. The ends of the metal pipes 1 and 2 are surrounded by a braided member 6 in which conductive metal fine wires are woven into a mesh shape, and the braided member 6 and the metal pipe 2 are connected by a metal band 7. Further, the braided member 6 and the metal pipe 2 connected by the metal band 7 are protected by the exterior 8 and then fixed by the binding band 9. At the ends of the metal pipes 1 and 2, the metal pipe 2 is connected to the metal pipe 1 to form an end face, thereby holding the cooling water 13 in the cavity 3. Further, at the end of the metal pipe 2, the tube 5 is connected to the hole 21, and the cooling water 13 from the BATT 30 is sent from the tube 5 to the cavity 3 through the hole 21. At the other ends of the metal pipes 1 and 2, the tube 4 is connected via the hole 21, and the cooling water 13 from the PCU 20 is sent from the tube 4 through the hole 21. Then, as shown in FIG. 4, the inside of the cavity 3 is filled with the cooling water 13. After that, the cooling water 13 in the cavity 3 flows into the cooling mechanism (not shown) provided in the PCU 20 and the BATT 30 through the tubes 4 and 5, and is cooled. That is, the heat generated in the electric wire 12 is efficiently transferred to the metal pipe 1 from the position where the electric wire 12 and the metal pipe 1 are in contact with each other, and the metal pipe 1 is cooled by the cooling water 13. By sending the cooling water 13 into the cavity 3 from both ends in the longitudinal direction of the metal pipe 2, the electric wire 12 can be uniformly cooled along the longitudinal direction. By flowing the cooling water 13 through the cavities 3 in the metal pipes 1 and 2 having the shielding function in this way, the generated electric wire 12 can be efficiently cooled. Since heat is generated when a large current is passed through the electric wire, it is necessary to thicken the electric wire to prevent overheating of the electric wire. However, according to this embodiment, the electric wire 12 can be cooled to suppress heat generation, so that the electric wire 12 is made thick. It is not necessary to do this, and the size of the electric wire can be reduced. The cooling water 13 may be sent from the tube 5 into the cavity 3 and discharged from the tube 4. In this case, for example, the cooling water 13 is returned by a flow path (not shown) from the PCU 20 to the BATT 30.

以上説明したように、本実施形態のシールド機能付高圧ワイヤハーネス１０によれば、金属パイプ１，２内の空洞３に冷却水１３を流すことで、発熱した電線１２を効率よく冷却できる。すなわち、本実施形態では、金属パイプ１，２によりシールド機能を実現するとともに、この金属パイプ１，２を活用して冷却水１３を流す水路（空洞３）を作り、電線１２を冷却することで過熱を防止して、電線１２のサイズダウンが可能となる。したがって、電線を包囲する金属パイプの径を小さくできるため、省スペースなシールド機能付高圧ワイヤハーネスを実現できる。 As described above, according to the high-voltage wire harness 10 with a shield function of the present embodiment, the generated electric wire 12 can be efficiently cooled by flowing the cooling water 13 through the cavities 3 in the metal pipes 1 and 2. That is, in the present embodiment, the shield function is realized by the metal pipes 1 and 2, and the metal pipes 1 and 2 are used to create a water channel (cavity 3) through which the cooling water 13 flows to cool the electric wire 12. Overheating can be prevented and the size of the electric wire 12 can be reduced. Therefore, since the diameter of the metal pipe surrounding the electric wire can be reduced, a space-saving high-voltage wire harness with a shielding function can be realized.
