Description
本発明はパイプハーネスの車体取付構造に関し、詳しくは、車両に配索する電線を金属パイプに挿通したパイプハーネスの車体パネルへの取り付けを省スペースで行うものである。
The present invention relates to a vehicle body mounting structure for a pipe harness. More specifically, the present invention is a space-saving installation of a pipe harness in which a wire routed in a vehicle is inserted into a metal pipe.
従来、ハイブリッド自動車または電気自動車のバッテリとインバータとの間やインバータとモータとの間を複数本の電線で接続しており、床下等の直線領域では前記電線をシールド用の金属パイプに挿通したパイプハーネスを配索している(特開2006-312409号公報参照)。
図4に示すように、前記パイプハーネス100は車室外Xと車室Yを仕切る車体パネル110に取り付けられ、金属パイプ102に挿通した複数本の電線101を車体パネル110に設けた貫通穴111に貫通させて車室Yに配線している。貫通穴111に挿通する電線101に対する防水性や防塵性の確保や金属パイプ102の固定、アース接続のために、ゴムシール材106を固定した金属製のブラケット103を金属パイプ102の前端近傍に取り付け、該ブラケット103を車体パネル110に固定している。 Conventionally, a plurality of electric wires are connected between a battery and an inverter of a hybrid vehicle or an electric vehicle, or between an inverter and a motor, and the electric wire is inserted into a shielding metal pipe in a straight region such as under the floor. A harness is routed (see JP 2006-312409 A).
As shown in FIG. 4, thepipe harness 100 is attached to a vehicle body panel 110 that partitions the exterior X and the interior Y, and a plurality of electric wires 101 inserted through the metal pipe 102 are inserted into through holes 111 provided in the vehicle body panel 110. It is penetrated and wired to the passenger compartment Y. A metal bracket 103 to which a rubber seal material 106 is fixed is attached in the vicinity of the front end of the metal pipe 102 in order to ensure waterproofness and dustproofness to the electric wire 101 inserted through the through hole 111, to fix the metal pipe 102, and to connect to the ground. The bracket 103 is fixed to the vehicle body panel 110.
図4に示すように、前記パイプハーネス100は車室外Xと車室Yを仕切る車体パネル110に取り付けられ、金属パイプ102に挿通した複数本の電線101を車体パネル110に設けた貫通穴111に貫通させて車室Yに配線している。貫通穴111に挿通する電線101に対する防水性や防塵性の確保や金属パイプ102の固定、アース接続のために、ゴムシール材106を固定した金属製のブラケット103を金属パイプ102の前端近傍に取り付け、該ブラケット103を車体パネル110に固定している。 Conventionally, a plurality of electric wires are connected between a battery and an inverter of a hybrid vehicle or an electric vehicle, or between an inverter and a motor, and the electric wire is inserted into a shielding metal pipe in a straight region such as under the floor. A harness is routed (see JP 2006-312409 A).
As shown in FIG. 4, the
具体的には、金属製のブラケット103は、金属パイプ102の外周面に加締め固定する小径筒部104と、小径筒部104に連続し内周面にゴムシール材106を固定した拡径筒部105と、該拡径筒部105の前端から外径方向に突設した固定部107とからなり、固定部107にはボルト締結のためのボルト穴108が穿設されていると共に、前記拡径筒部105に内嵌固定したゴムシール材106の大径側前端面には環状のシールリップ部106aを突設している。複数本の電線101が挿通される金属パイプ102の前端近傍の外周面に前記ブラケット103の小径筒部104を加締め固定し、車体パネル110のボルト穴112に連通する固定部107のボルト穴108にボルトBを通して締結することによってブラケット103と車体パネル110とを固定している。このようなブラケット103と車体パネル110との固定により、金属パイプ102の車体パネル110への固定ならびにアース接続が可能となると共に、ゴムシール材106前端面のシールリップ部106aが貫通穴111周囲の車体パネル110に押し当てられて、金属パイプ102の前端開口から引き出される電線101を貫通する貫通穴111のシール性を確保している。
Specifically, the metal bracket 103 includes a small-diameter cylindrical portion 104 that is caulked and fixed to the outer peripheral surface of the metal pipe 102, and a large-diameter cylindrical portion that is continuous to the small-diameter cylindrical portion 104 and has a rubber seal material 106 fixed to the inner peripheral surface. 105 and a fixing portion 107 protruding in the outer diameter direction from the front end of the enlarged diameter cylindrical portion 105. The fixing portion 107 has a bolt hole 108 for fastening a bolt, and the diameter expansion An annular seal lip portion 106 a is projected from the front end surface of the large-diameter side of the rubber seal material 106 fitted and fixed to the tube portion 105. The small diameter cylindrical portion 104 of the bracket 103 is caulked and fixed to the outer peripheral surface near the front end of the metal pipe 102 through which the plurality of electric wires 101 are inserted, and the bolt hole 108 of the fixing portion 107 communicating with the bolt hole 112 of the vehicle body panel 110. The bracket 103 and the vehicle body panel 110 are fixed to each other by fastening them through bolts B. By fixing the bracket 103 and the vehicle body panel 110 in this manner, the metal pipe 102 can be fixed to the vehicle body panel 110 and connected to the ground, and the seal lip portion 106a on the front end surface of the rubber seal member 106 has a vehicle body around the through hole 111. The sealability of the through hole 111 that is pressed against the panel 110 and penetrates the electric wire 101 drawn from the front end opening of the metal pipe 102 is ensured.
しかし、前記のようなゴムシール材106を貫通穴111の周囲の車体パネル110面に押し当てて貫通穴111をシールする面シール構造では、一定のシール性を確保するために、貫通穴111の開口面積を電線101を挿通する金属パイプ102の断面積の5倍程度にまで大きくする必要がある。したがって、パイプハーネス100の車体パネル110への取り付けに要するスペースが大きくなり、パイプハーネス100の取り付け可能な箇所が限定されてしまうという問題がある。
However, in the face seal structure in which the rubber seal material 106 is pressed against the surface of the vehicle body panel 110 around the through hole 111 to seal the through hole 111, the opening of the through hole 111 is secured in order to ensure a certain sealing property. The area needs to be increased to about 5 times the cross-sectional area of the metal pipe 102 through which the electric wire 101 is inserted. Therefore, there is a problem that a space required for attaching the pipe harness 100 to the vehicle body panel 110 is increased, and a place where the pipe harness 100 can be attached is limited.

An annular rubber seal 9 is continuously fitted to the metal pipe 3 continuously to the rear end of the front retainer 4, and is fixed to the vehicle body panel 20 and is swaged and fixed to the metal pipe 3. A rubber seal material 9 is held between the front retainer 4 and the front retainer 4. Therefore, a shaft seal structure in which the front retainer 4 is passed through the through hole 21 of the vehicle body panel 20 and the rubber seal material 9 on the rear end side is pressed against the inner peripheral surface of the through hole 21 to seal the through hole 21 can be obtained. The opening area of the through hole 21 can be reduced to the same level as the cross-sectional area of the metal pipe 3 while maintaining high sealing performance. Therefore, the pipe harness 1 can be attached in a space-saving manner, and the attachment location to the vehicle body panel 20 is hardly restricted, so that the routing route can be set more freely.
また、前記のように車体パネル20に穿設する貫通穴21の開口面積を小さくできるため、金属パイプ3を車体パネル20に固定、アース接続するためのブラケット11の固定部13も小型化できる。さらに、前記円筒形状のフロントリテーナ4は比較的安価な樹脂成形品であり、該フロントリテーナ4の後端に連続して外嵌するゴムシール材9も小型の環状ゴム材であるため、製造コストを抑えることができる。
Further, since the opening area of the through hole 21 formed in the vehicle body panel 20 can be reduced as described above, the fixing portion 13 of the bracket 11 for fixing the metal pipe 3 to the vehicle body panel 20 and connecting to the ground can also be reduced in size. Further, the cylindrical front retainer 4 is a relatively inexpensive resin molded product, and the rubber seal material 9 that is continuously fitted to the rear end of the front retainer 4 is also a small annular rubber material. Can be suppressed.
