Description

ワイヤハーネスWire harness
　本発明は、ワイヤハーネスに関するものである。 The present invention relates to a wire harness.
　従来、ハイブリッド車や電気自動車等の車両に用いられるワイヤハーネスとしては、電線部材の外側がコルゲートチューブや樹脂パイプ等の外装部材で覆われたワイヤハーネスが知られている。この種のワイヤハーネスは、車両床下等に配索されて外部に晒される場合がある。そこで、外装部材の内部への水の浸入を抑制するために、外装部材の開口部を塞ぐ弁部材を設ける技術が提案されている（例えば、特許文献１参照）。この弁部材には、電線部材の挿通させるためのスリットが形成されている。 Conventionally, as a wire harness used in a vehicle such as a hybrid vehicle or an electric vehicle, a wire harness in which the outer side of an electric wire member is covered with an exterior member such as a corrugated tube or a resin pipe is known. This type of wire harness may be routed under the floor of the vehicle or the like and exposed to the outside. Therefore, in order to prevent water from entering the inside of the exterior member, a technique of providing a valve member that closes the opening of the exterior member has been proposed (for example, see Patent Document 1). The valve member is formed with a slit for inserting the electric wire member.
特開２００１－２５１７３６号公報JP 2001-251736 A
　ところで、上述した弁部材にはスリットが形成されているため、揺動・振動や電線部材の自重などによって電線部材が動いた場合に、弁部材の変形が生じて弁部材と電線部材との間に隙間が発生するおそれがある。弁部材と電線部材との間に隙間が発生すると、その隙間を通じて外装部材の内部に水や砂が浸入するおそれがある。なお、砂等の異物が外装部材の内部に浸入することは、電線部材が傷つく原因となる。 By the way, since the above-mentioned valve member has slits, when the electric wire member moves due to rocking / vibration or the self-weight of the electric wire member, the valve member is deformed to cause a gap between the valve member and the electric wire member. There may be a gap in If a gap occurs between the valve member and the electric wire member, water or sand may enter the interior of the exterior member through the gap. It should be noted that the intrusion of foreign matter such as sand into the exterior member causes damage to the electric wire member.
　本発明は上記問題点を解決するためになされたものであって、その目的は、電線部材を良好に保護することが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 to solve the above-mentioned problems, and an object thereof is to provide a wire harness capable of satisfactorily protecting electric wire members.
　上記課題を解決するワイヤハーネスによれば、電線部材が挿通される筒状の外装部材と、前記電線部材の外周面と前記外装部材の内周面との間の隙間を塞ぐように設けられた弁部材と、を有し、前記弁部材は、第１方向に延びるスリットを有する第１弁と、前記第１弁と前記電線部材の挿通方向に並んで設けられ、前記第１方向とは異なる第２方向に延びるスリットを有する第２弁とを有している。 According to the wire harness that solves the above-mentioned problems, the tubular outer member through which the electric wire member is inserted, and the outer peripheral surface of the electric wire member and the inner peripheral surface of the outer member are provided so as to close the gap. A first valve having a slit extending in a first direction, and the valve member is provided side by side in the insertion direction of the first valve and the electric wire member, and is different from the first direction.

Further, in a state where the plurality of divided tubular portions 40 and 50 are combined, the tip end surface 77A of the electric wire holding portion 71A of the valve member 42 and the tip end surface 77B of the electric wire holding portion 71B of the valve member 52 are in contact with each other. At this time, the insertion hole 79 is formed by the recess 79A of the valve member 42 and the recess 79B of the valve member 52. The insertion hole 79 of the present embodiment is formed in a cylindrical shape that can be fitted to the outer periphery of the electric wire member 20. Note that FIG. 5 illustrates only the wire holding portions 70A, 71A, 70B, 71B and the split valves 80A, 81A, 80B, 81B of the valve members 42, 52 in an exploded manner, and the base portions 60A, 60B are shown. Is omitted.
　図２に示すように、挿通孔７８と挿通孔７９とは、例えば、プロテクタ３２の長さ方向において重なる位置に形成されている。換言すると、挿通孔７８と挿通孔７９とは、電線部材２０の挿通方向において重なる位置に形成されている。 As shown in FIG. 2, the insertion hole 78 and the insertion hole 79 are formed, for example, at positions that overlap each other in the length direction of the protector 32. In other words, the insertion hole 78 and the insertion hole 79 are formed at a position where they overlap with each other in the insertion direction of the electric wire member 20.
　挿通孔７８，７９は、プロテクタ３２の開口部、つまり本体部４１，５１の開口部よりも小さく形成されている。挿通孔７８は、電線部材２０の外径寸法よりも一回り大きくなるように形成されている。例えば、挿通孔７８は、挿通孔７８の内周面と電線部材２０の外周面との間に分割弁８０Ａ，８１Ａ，８０Ｂ，８１Ｂが配置可能な程度に電線部材２０の外形寸法よりも一回り大きく形成されている。挿通孔７９は、挿通孔７８と同じ大きさに形成してもよいし、挿通孔７８よりも一回り小さく形成してもよい。挿通孔７９を挿通孔７８よりも小さく形成する場合には、挿通孔７９は、例えば、その内周面が電線部材２０の外周面に当接するように形成される。これら挿通孔７８，７９が電線部材２０を保持する電線保持部として機能する。具体的には、挿通孔７８，７９は、プロテクタ３２の開口部よりも小さく形成されているため、挿通された電線部材２０のプロテクタ３２内でのばたつきを抑制することができる。 The insertion holes 78, 79 are formed to be smaller than the opening of the protector 32, that is, the opening of the main body 41, 51. The insertion hole 78 is formed to be slightly larger than the outer diameter dimension of the electric wire member 20. For example, the insertion hole 78 is slightly larger than the outer dimension of the electric wire member 20 to the extent that the split valves 80A, 81A, 80B, 81B can be arranged between the inner peripheral surface of the insertion hole 78 and the outer peripheral surface of the electric wire member 20. Largely formed. The insertion hole 79 may be formed to have the same size as the insertion hole 78, or may be formed to be slightly smaller than the insertion hole 78. When the insertion hole 79 is formed smaller than the insertion hole 78, the insertion hole 79 is formed, for example, so that the inner peripheral surface thereof abuts the outer peripheral surface of the electric wire member 20. These insertion holes 78 and 79 function as an electric wire holding portion that holds the electric wire member 20. Specifically, since the insertion holes 78 and 79 are formed smaller than the opening of the protector 32, it is possible to suppress the fluttering of the inserted wire member 20 in the protector 32.
　図４に示すように、電線保持部７０Ａの凹部７８Ａの端面７３Ａ側の開口端縁は、丸みを帯びた形状に形成されている。換言すると、凹部７８Ａの端面７３Ａ側の開口端縁の角部がＲ形状に形成されている。また、電線保持部７０Ａの先端面７４Ａの端面７３Ａ側の角部は、丸みを帯びた形状に形成されている。 As shown in FIG. 4, the opening edge on the end face 73A side of the recess 78A of the wire holding portion 70A is formed in a rounded shape. In other words, the corner of the opening edge on the end face 73A side of the recess 78A is formed in an R shape. In addition, the corner portion of the tip end surface 74A of the wire holding portion 70A on the end surface 73A side is formed in a rounded shape.
　複数の分割弁８０Ａ，８１Ａは、電線部材２０の挿通方向（図４の左右方向）に沿って並んで設けられている。複数の分割弁８０Ａ，８１Ａは、例えば、一対の電線保持部７０Ａ，７１Ａの間に形成された収容溝４４Ａに設けられている。各分割弁８０Ａ，８１Ａは、例えば、薄板状や膜状に形成されている。各分割弁８０Ａ，８１Ａは、例えば、土台部６０Ａの先端面から分割筒部４０の内側に向かって突出するように形成されている。すなわち、各分割弁８０Ａ，８１Ａは、土台部６０Ａの先端面からプロテクタ３２の中心軸に向かって突出するように形成されている。例えば、各分割弁８０Ａ，８１Ａは、その基端部が土台部６０Ａに埋設されている。本実施形態の各分割弁８０Ａ，８１Ａは、外力の加わっていない自然状態において、プロテクタ３２の端面３２Ａ側に傾くように形成されている。すなわち、各分割弁８０Ａ，８１Ａは、電線部材２０が挿通される前の単独の状態において、プロテクタ３２の端面３２Ａ側に傾くように形成されている。換言すると、各分割弁８０Ａ，８１Ａは、基端部から先端部に向かうにつれてプロテクタ３２の端面３２Ａに近づくように形成されている。分割弁８０Ａの傾斜角度と分割弁８１Ａの傾斜角度とは、互いに同じ角度であってもよいし、互いに異なる角度であってもよい。分割弁８０Ａ，８１Ａの厚さは、例えば、本体部４１の厚さよりも薄く、電線保持部７０Ａ，７１Ａの厚さよりも薄く設定されている。分割弁８０Ａ，８１Ａの厚さは、例えば、０．５～１．５ｍｍ程度とすることができる。 The plurality of split valves 80A and 81A are provided side by side along the insertion direction of the electric wire member 20 (left and right direction in FIG. 4). The plurality of split valves 80A, 81A are provided, for example, in a housing groove 44A formed between a pair of electric wire holding portions 70A, 71A. Each of the division valves 80A and 81A is formed in a thin plate shape or a film shape, for example. Each of the split valves 80A and 81A is formed, for example, so as to project from the tip end surface of the base portion 60A toward the inside of the split tubular portion 40. That is, each of the division valves 80A and 81A is formed so as to project from the tip end surface of the base portion 60A toward the central axis of the protector 32. For example, the base ends of the respective division valves 80A and 81A are embedded in the base portion 60A. Each of the split valves 80A and 81A of the present embodiment is formed so as to incline toward the end surface 32A side of the protector 32 in a natural state where no external force is applied. That is, each of the split valves 80A and 81A is formed so as to incline toward the end surface 32A side of the protector 32 in a single state before the electric wire member 20 is inserted. In other words, each of the split valves 80A and 81A is formed so as to approach the end surface 32A of the protector 32 from the base end portion toward the tip end portion. The inclination angle of the division valve 80A and the inclination angle of the division valve 81A may be the same as each other or may be different from each other. The thickness of the split valves 80A and 81A is set to be thinner than that of the main body 41 and thinner than that of the wire holding portions 70A and 71A, for example. The thickness of the split valves 80A and 81A can be set to, for example, about 0.5 to 1.5 mm.
　各分割弁８０Ａ，８１Ａの材料としては、例えば、土台部６０Ａと同じ材料であってもよいし、土台部６０Ａと異なる材料であってもよい。土台部６０Ａと材料が異なる場合の各分割弁８０Ａ，８０Ｂの材料として、例えば、シリコンやゴムなどの土台部６０Ａよりも柔軟性に優れた材料を用いることができる。分割弁８０Ａの材料と分割弁８０Ｂの材料とは、互いに異なる材料であってもよいし、互いに同じ材料であってもよい。なお、各分割弁８０Ａ，８１Ａと土台部６０Ａとの材料が異なる場合には、各分割弁８０Ａ，８１Ａは、例えば、二色成形によって土台部６０Ａと一体化されている。 The material of each of the dividing valves 80A and 81A may be the same as that of the base portion 60A or may be different from that of the base portion 60A. As a material of each of the division valves 80A and 80B when the material is different from that of the base portion 60A, for example, a material such as silicon or rubber which is more flexible than the base portion 60A can be used. The material of the division valve 80A and the material of the division valve 80B may be different materials or may be the same material. When the materials of the respective division valves 80A, 81A and the base portion 60A are different, the respective division valves 80A, 81A are integrated with the base portion 60A by, for example, two-color molding.
　図５に示すように、複数の分割筒部４０，５０が合体した状態では、弁部材４２の分割弁８０Ａの先端面と、弁部材５２の分割弁８０Ｂの先端面とが当接する。これら分割弁８０Ａと分割弁８０Ｂとによって１つの弁８０が形成される。また、複数の分割筒部４０，５０が合体した状態では、弁部材４２の分割弁８１Ａの分割面と、弁部材５２の分割弁８１Ｂの分割面とが当接する。これら分割弁８１Ａと分割弁８１Ｂとによって１つの弁８１が形成される。弁８０，８１は、例えば、プロテクタ３２（図２参照）の開口部を塞ぐように形成されている。 As shown in FIG. 5, when the plurality of split cylindrical portions 40, 50 are combined, the tip surface of the split valve 80A of the valve member 42 and the tip surface of the split valve 80B of the valve member 52 contact each other. The split valve 80A and the split valve 80B form one valve 80. Further, in a state in which the plurality of divided tubular portions 40 and 50 are combined, the divided surface of the divided valve 81A of the valve member 42 and the divided surface of the divided valve 81B of the valve member 52 are in contact with each other. One valve 81 is formed by the split valve 81A and the split valve 81B. The valves 80 and 81 are formed so as to close the opening of the protector 32 (see FIG. 2), for example.
　弁８０は、１本又は複数本（ここでは、２本）のスリットＳ１，Ｓ２を有している。スリットＳ１，Ｓ２は、電線部材２０の挿通方向において挿通孔７８と重なる挿通領域８０Ｘに位置する部分の弁８０に形成されている。スリットＳ１は、第１方向、ここでは分割筒部４０，５０の合体方向に延びるように形成されている。スリットＳ２は、例えば、第１方向と直交する第２方向、ここでは車両幅方向に延びるように形成されている。これらスリットＳ１，Ｓ２は、例えば、挿通孔７８の中心軸Ａ１を通るように形成されている。なお、本実施形態では、挿通孔７８の中心軸Ａ１は、プロテクタ３２の中心軸と一致している。ここで、本実施形態のスリットＳ２は、分割弁８０Ａの先端面と分割弁８０Ｂの先端面との間の隙間によって構成されている。すなわち、スリットＳ２は、分割弁８０Ａと分割弁８０Ｂとの分割面によって構成されている。このため、スリットＳ２は、弁８０の車両幅方向の全長に亘って延びるように形成されている。一方で、本実施形態のスリットＳ１は、挿通領域８０Ｘに位置する部分の弁８０のみに形成されている。 The valve 80 has one or more (here, two) slits S1 and S2. The slits S1 and S2 are formed in the valve 80 at a portion located in the insertion area 80X that overlaps the insertion hole 78 in the insertion direction of the electric wire member 20. The slit S1 is formed so as to extend in the first direction, here, the joining direction of the split cylindrical portions 40, 50. The slit S2 is formed, for example, so as to extend in a second direction orthogonal to the first direction, here the vehicle width direction. These slits S1 and S2 are formed, for example, so as to pass through the central axis A1 of the insertion hole 78. In addition, in this embodiment, the central axis A1 of the insertion hole 78 coincides with the central axis of the protector 32. Here, the slit S2 of the present embodiment is formed by a gap between the tip surface of the split valve 80A and the tip surface of the split valve 80B. That is, the slit S2 is configured by the division surface of the division valve 80A and the division valve 80B. Therefore, the slit S2 is formed so as to extend over the entire length of the valve 80 in the vehicle width direction. On the other hand, the slit S1 of the present embodiment is formed only in the valve 80 in the portion located in the insertion area 80X.
　分割弁８１Ａは、１本又は複数本（ここでは、２本）のスリットＳ３，Ｓ４を有している。スリットＳ３，Ｓ４は、電線部材２０の挿通方向において挿通孔７８と重なる挿通領域８１Ｘに位置する部分の弁８１に形成されている。スリットＳ３は、第１方向（分割筒部３０，４０の合体方向）及び第２方向（車両幅方向）の双方と交差する第３方向に延びるように形成されている。スリットＳ４は、例えば、第１方向及び第２方向と交差する方向であって、第３方向と直交する第４方向に延びるように形成されている。これらスリットＳ３，Ｓ４は、例えば、挿通孔７８の中心軸Ａ１を通るように形成されている。ここで、本実施形態のスリットＳ３，Ｓ４は、分割弁８１Ａの分割面と分割弁８１Ｂの分割面との間の隙間によって構成されている。ここで、本実施形態の分割弁８１Ａの分割面は、第４方向に延びる端面８３と、その端面８３の両端部からそれぞれ第１方向に延びる端面８４，８５とを有している。このような分割面を有する分割弁８１Ａは、先端部が他方の弁部材５２の収容溝４４Ｂ（図４参照）まで延びるように形成されている。本実施形態の分割弁８１Ａは、複数の分割筒部４０，５０が合体した状態において、基端部が自身の弁部材４２の収容溝４４Ａ（図４参照）に収容されるとともに、先端部が他方の弁部材５２の収容溝４４Ｂ（図４参照）に収容されている。 The split valve 81A has one or a plurality (here, two) of slits S3 and S4. The slits S3 and S4 are formed in the valve 81 at a portion located in the insertion area 81X that overlaps the insertion hole 78 in the insertion direction of the electric wire member 20. The slit S3 is formed so as to extend in a third direction that intersects both the first direction (the direction in which the split cylindrical portions 30 and 40 are merged) and the second direction (the vehicle width direction). The slit S4 is formed, for example, in a direction intersecting the first direction and the second direction and extending in the fourth direction orthogonal to the third direction. These slits S3 and S4 are formed, for example, so as to pass through the central axis A1 of the insertion hole 78. Here, the slits S3 and S4 of the present embodiment are formed by a gap between the split surface of the split valve 81A and the split surface of the split valve 81B. Here, the split surface of the split valve 81A of the present embodiment has an end face 83 extending in the fourth direction, and end faces 84, 85 extending in the first direction from both ends of the end face 83, respectively. 81 A of division | segmentation valves which have such a division | segmentation surface are formed so that a front-end | tip part may extend to the accommodation groove 44B (refer FIG. 4) of the other valve member 52. In the split valve 81A of the present embodiment, the base end portion is stored in the storage groove 44A (see FIG. 4) of the valve member 42 of its own and the tip end portion is in the state where the plurality of split cylindrical portions 40, 50 are combined. It is housed in the housing groove 44B (see FIG. 4) of the other valve member 52.
　図２に示すように、弁８０，８１は、プロテクタ３２に電線部材２０が挿通された状態において、電線部材２０の外周面に沿って倒れるように変形する。例えば、弁８０は、スリットＳ１，Ｓ２（図５参照）によって分割された分割単位毎に、プロテクタ３２の端面３２Ａ側に向かって倒れるように変形する。例えば、弁８１は、スリットＳ３，Ｓ４（図５参照）によって分割された分割単位毎に、プロテクタ３２の端面３２Ａ側に向かって倒れるように変形する。変形した弁８０，８１は、例えば、電磁シールド部材２２を電線２１の外周面に向かって押圧するように、電磁シールド部材２２の外周面に密着している。具体的には、変形した弁８０，８１は、電線２１の外周面と弁８０，８１との間に隙間が無くなるように、電磁シールド部材２２を電線２１の外周面に向かって押圧している。これら弁８０，８１によって、本体部４１，５１の内周面と電線２１の外周面との間の隙間を好適に無くすことができる。但し、図３に示すように、単独の弁８０では、揺動・振動や電線部材２０の自重などによって電線部材２０が動いた場合に、弁８０に意図しない変形が生じて弁８０と電線部材２０との間に隙間８０Ｓが発生する場合がある。これに対し、本実施形態では、複数の弁８０，８１を電線部材２０の挿通方向に並べて設け、弁８０に形成するスリットＳ１，Ｓ２（図５参照）と弁８１に形成するスリットＳ３，Ｓ４（図５参照）との向きを互いに異なる方向に設定した。これにより、一方の弁８０と電線部材２０との間に隙間８０Ｓが発生した場合であっても、その隙間８０Ｓでは他方の弁８１を電線部材２０に密着させることができる。このため、電線部材２０の周方向全周に亘って、弁８０，８１と電線部材２０との間に隙間が発生することを好適に抑制することができる。この結果、電線部材２０の周方向全周に亘って、本体部４１，５１の内周面と電線部材２０の外周面との間に隙間が発生することを好適に抑制することができる。したがって、弁８０，８１よりも内方側のプロテクタ３２の内部空間に、水や砂などの異物が浸入することを好適に抑制することができる。 As shown in FIG. 2, the valves 80 and 81 are deformed so as to fall along the outer peripheral surface of the electric wire member 20 when the electric wire member 20 is inserted into the protector 32. For example, the valve 80 is deformed so as to fall toward the end surface 32A side of the protector 32 for each division unit divided by the slits S1 and S2 (see FIG. 5). For example, the valve 81 is deformed so as to fall toward the end face 32A side of the protector 32 for each division unit divided by the slits S3, S4 (see FIG. 5). The deformed valves 80 and 81 are in close contact with the outer peripheral surface of the electromagnetic shield member 22 so as to press the electromagnetic shield member 22 toward the outer peripheral surface of the electric wire 21, for example. Specifically, the deformed valves 80 and 81 press the electromagnetic shield member 22 toward the outer peripheral surface of the electric wire 21 so that there is no gap between the outer peripheral surface of the electric wire 21 and the valves 80 and 81. .. With these valves 80 and 81, it is possible to preferably eliminate the gap between the inner peripheral surfaces of the main body portions 41 and 51 and the outer peripheral surface of the electric wire 21. However, as shown in FIG. 3, with the independent valve 80, when the electric wire member 20 moves due to rocking / vibration or the self-weight of the electric wire member 20, unintended deformation occurs in the valve 80 and the electric wire member 20. There may be a gap 80S between the gap 20 and 20. On the other hand, in the present embodiment, a plurality of valves 80 and 81 are provided side by side in the insertion direction of the electric wire member 20, and slits S1 and S2 (see FIG. 5) formed in the valve 80 and slits S3 and S4 formed in the valve 81. (See FIG. 5) are set in different directions. Accordingly, even when the gap 80S is generated between the valve 80 and the electric wire member 20, the other valve 81 can be brought into close contact with the electric wire member 20 in the gap 80S. Therefore, it is possible to preferably suppress the occurrence of a gap between the valves 80 and 81 and the electric wire member 20 over the entire circumference of the electric wire member 20 in the circumferential direction. As a result, it is possible to preferably suppress the occurrence of a gap between the inner peripheral surfaces of the main body portions 41 and 51 and the outer peripheral surface of the electric wire member 20 over the entire circumference of the electric wire member 20. Therefore, it is possible to preferably prevent foreign matter such as water or sand from entering the internal space of the protector 32 on the inner side of the valves 80 and 81.
　プロテクタ３２は、複数の分割筒部４０，５０を合体状態に保持する１つ又は複数のロック構造９０を有している。ロック構造９０は、互いに係止可能なロック部９１及びロック受け部９２を有している。各分割筒部４０，５０は、例えば、ロック部９１及びロック受け部９２の双方を有している。ロック部９１及びロック受け部９２は、例えば、本体部４１，５１の周方向端部の外周面に設けられている。ロック部９１は、例えば、分割筒部４０，５０の合体方向（図３の上下方向）に突出して形成されている。ロック部９１の突出先端部の外面には爪部９３が外側に突出するように形成されている。ロック受け部９２は、ロック部９１が貫通可能な穴部９４を有している。ロック受け部９２の穴部９４の周縁部にロック部９１の爪部９３が係止することで、ロック構造９０がロック状態となる。 The protector 32 has one or a plurality of lock structures 90 that hold the plurality of divided cylindrical portions 40 and 50 in a united state. The lock structure 90 has a lock portion 91 and a lock receiving portion 92 that can be locked with each other. Each of the divided tubular portions 40 and 50 has, for example, both a lock portion 91 and a lock receiving portion 92. The lock portion 91 and the lock receiving portion 92 are provided, for example, on the outer peripheral surfaces of the circumferential end portions of the main body portions 41 and 51. The lock portion 91 is formed, for example, so as to project in the direction in which the split cylindrical portions 40 and 50 are combined (the vertical direction in FIG. 3). A claw portion 93 is formed on the outer surface of the protruding tip portion of the lock portion 91 so as to protrude outward. The lock receiving portion 92 has a hole portion 94 through which the lock portion 91 can pass. The pawl portion 93 of the lock portion 91 is locked to the peripheral portion of the hole portion 94 of the lock receiving portion 92, so that the lock structure 90 is brought into the locked state.
　図２に示すように、プロテクタ３２の端面３２Ａを有する一端部とその一端部から導出された電線部材２０との間は、例えば、プロテクタ３２の一端部の外周と電線部材２０の外周とに亘って巻かれるテープ９５によって閉塞されている。 As shown in FIG. 2, between one end portion having the end surface 32A of the protector 32 and the electric wire member 20 led out from the one end portion, for example, the outer circumference of the one end portion of the protector 32 and the outer circumference of the electric wire member 20 are provided. It is closed by a tape 95 to be wound up.
　次に、ワイヤハーネス１０の製造方法の一例について説明する。
　図４に示すように、電線２１とその電線２１の外周を包囲する電磁シールド部材２２とを有する電線部材２０を準備するとともに、複数の分割筒部４０，５０を準備する。続いて、複数の分割筒部４０，５０を、それらの間に電線部材２０を挟むようにして合体させる。これら分割筒部４０，５０の合体時に、分割弁８０Ａ，８１Ａ，８０Ｂ，８１Ｂが分割筒部４０，５０の合体方向から電線部材２０の外周面に接触する。このとき、分割弁８０Ａ，８１Ａ，８０Ｂ，８１Ｂがあらかじめプロテクタ３２の端面３２Ａ側に傾くように形成されている。このため、分割筒部４０，５０の合体時に、分割弁８０Ａ，８１Ａ，８０Ｂ，８１Ｂに対して合体方向から外力が加わると、それら分割弁８０Ａ，８１Ａ，８０Ｂ，８１Ｂが電線部材２０の外周面に追従して端面３２Ａ側に倒れるように変形する。その後、図３に示したロック構造９０によりロック状態とされ、複数の分割筒部４０，５０の合体状態が保持される。 Next, an example of a method for manufacturing the wire harness 10 will be described.
As shown in FIG. 4, an electric wire member 20 having an electric wire 21 and an electromagnetic shield member 22 surrounding the outer circumference of the electric wire 21 is prepared, and a plurality of split cylinder portions 40, 50 are prepared. Then, the plurality of divided tubular portions 40 and 50 are combined so that the electric wire member 20 is sandwiched between them. When the split cylindrical portions 40, 50 are combined, the split valves 80A, 81A, 80B, 81B come into contact with the outer peripheral surface of the electric wire member 20 from the merged direction of the split cylindrical portions 40, 50. At this time, the split valves 80A, 81A, 80B, 81B are formed in advance so as to be inclined toward the end surface 32A of the protector 32. Therefore, when an external force is applied to the split valves 80A, 81A, 80B, 81B from the joining direction when the split tubular portions 40, 50 are joined, the split valves 80A, 81A, 80B, 81B are moved to the outer peripheral surface of the wire member 20. And is deformed so as to fall toward the end face 32A side. After that, the lock structure 90 shown in FIG. 3 sets the lock state, and the united state of the plurality of divided cylindrical portions 40 and 50 is held.
　次に、本実施形態の作用効果を説明する。
　（１）複数の弁８０，８１を電線部材２０の挿通方向に並べて設け、弁８０に形成するスリットＳ１，Ｓ２と弁８１に形成するスリットＳ３，Ｓ４との向きを互いに異なる方向に設定した。これにより、一方の弁８０と電線部材２０との間に隙間８０Ｓが発生した場合であっても、その隙間８０Ｓでは他方の弁８１を電線部材２０に密着させることができる。このため、電線部材２０の周方向全周に亘って、弁８０，８１と電線部材２０との間に隙間が発生することを好適に抑制することができる。この結果、電線部材２０の周方向全周に亘って、本体部４１，５１の内周面と電線部材２０の外周面との間に隙間が発生することを好適に抑制することができる。したがって、弁８０，８１よりも内方側のプロテクタ３２の内部空間に、水や砂などの異物が浸入することを好適に抑制することができる。これにより、電線部材２０を良好に保護することができる。 Next, the function and effect of this embodiment will be described.
(1) A plurality of valves 80 and 81 are arranged side by side in the insertion direction of the electric wire member 20, and the slits S1 and S2 formed in the valve 80 and the slits S3 and S4 formed in the valve 81 are set in different directions. Accordingly, even when the gap 80S is generated between the valve 80 and the electric wire member 20, the other valve 81 can be brought into close contact with the electric wire member 20 in the gap 80S. Therefore, it is possible to preferably suppress the occurrence of a gap between the valves 80 and 81 and the electric wire member 20 over the entire circumference of the electric wire member 20 in the circumferential direction. As a result, it is possible to preferably suppress the occurrence of a gap between the inner peripheral surfaces of the main body portions 41 and 51 and the outer peripheral surface of the electric wire member 20 over the entire circumference of the electric wire member 20. Therefore, it is possible to preferably prevent foreign matter such as water or sand from entering the internal space of the protector 32 on the inner side of the valves 80 and 81. Thereby, the electric wire member 20 can be well protected.
　（２）プロテクタ３２を、複数の分割筒部４０，５０を組み合わせて構成した。また、複数の分割弁８０Ａ，８０Ｂを組み合わせて１つの弁８０を構成し、複数の分割弁８１Ａ，８１Ｂを組み合わせて１つの弁８１を構成した。これら弁８０，８１には、その分割面に必ず１つのスリットＳ２，Ｓ４が形成されることになる。したがって、本構成では、弁８０，８１と電線部材２０の外周面との間に隙間が生じやすくなる。このため、本構成を採用する場合には、上記（１）で説明した作用効果が顕著になる。 (2) The protector 32 is configured by combining a plurality of divided cylindrical portions 40 and 50. Further, a plurality of split valves 80A and 80B are combined to form one valve 80, and a plurality of split valves 81A and 81B are combined to form one valve 81. One slit S2, S4 is always formed on the dividing surface of each of the valves 80, 81. Therefore, in this configuration, a gap is likely to be formed between the valves 80 and 81 and the outer peripheral surface of the electric wire member 20. Therefore, when the present configuration is adopted, the function and effect described in (1) above becomes remarkable.
　（３）弁部材４３をプロテクタ３２の長さ方向の端面３２Ａの近傍に設けるようにした。この構成によれば、プロテクタ３２の長さ方向の中央部に弁部材４３を設ける場合に比べて、端面３２Ａの近傍に設けた弁部材４３によって、プロテクタ３２の内部空間に水や砂が浸入することを好適に抑制できる。 (3) The valve member 43 is provided near the lengthwise end face 32A of the protector 32. According to this configuration, as compared with the case where the valve member 43 is provided at the central portion in the length direction of the protector 32, the valve member 43 provided in the vicinity of the end face 32A allows water and sand to enter the internal space of the protector 32. This can be suitably suppressed.
　（４）分割弁８０Ａ，８１Ａ，８０Ｂ，８１Ｂを、外力の加わっていない状態において、プロテクタ３２の長さ方向の端面３２Ａ側に傾くように設けた。これにより、複数の分割筒部４０，５０を合体させるときに、分割弁８０Ａ，８１Ａ，８０Ｂ，８１Ｂを電線部材２０の外周面に追従して端面３２Ａ側に倒れるように変形させることができる。この結果、変形した分割弁８０Ａ，８１Ａ，８０Ｂ，８１Ｂと電線部材２０の外周面との間に、水や砂等の異物が溜まることを抑制できる。 (4) The split valves 80A, 81A, 80B, 81B are provided so as to incline toward the end face 32A side in the longitudinal direction of the protector 32 when no external force is applied. This allows the split valves 80A, 81A, 80B, 81B to be deformed so as to follow the outer peripheral surface of the electric wire member 20 and fall toward the end surface 32A when the plurality of split tubular portions 40, 50 are combined. As a result, it is possible to suppress the accumulation of foreign matter such as water or sand between the deformed split valves 80A, 81A, 80B, 81B and the outer peripheral surface of the electric wire member 20.
　（５）電線部材２０を保持する一対の電線保持部７０Ａ，７１Ａ，７０Ｂ，７１Ｂの間に弁８０，８１を設けた。電線保持部７０Ａ，７１Ａ，７０Ｂ，７１Ｂによって電線部材２０の移動が規制されるため、電線部材２０のばたつきを抑制できる。これにより、電線部材２０の移動に伴う弁８０，８１の意図しない変形が発生することを好適に抑制できる。この結果、弁８０，８１と電線部材２０との間に隙間が発生することを好適に抑制することができる。 (5) Valves 80, 81 are provided between the pair of electric wire holding portions 70A, 71A, 70B, 71B for holding the electric wire member 20. Since the movement of the electric wire member 20 is restricted by the electric wire holding portions 70A, 71A, 70B, 71B, the fluttering of the electric wire member 20 can be suppressed. As a result, it is possible to preferably suppress unintended deformation of the valves 80 and 81 due to the movement of the electric wire member 20. As a result, it is possible to preferably suppress the occurrence of a gap between the valves 80 and 81 and the electric wire member 20.
　（６）本体部４１，５１の内周面に、その内周面と一体に弁部材４２，５２を形成するようにした。この構成によれば、プロテクタ３２に電線部材２０を挿通する作業と同時に、弁８０，８１によってプロテクタ３２と電線部材２０との間の隙間を塞ぐ構造を形成することができる。 (6) The valve members 42 and 52 are formed integrally with the inner peripheral surfaces of the main body portions 41 and 51. According to this configuration, at the same time when the electric wire member 20 is inserted into the protector 32, it is possible to form a structure in which the valves 80 and 81 close the gap between the protector 32 and the electric wire member 20.
　（他の実施形態）
　上記実施形態は、以下のように変更して実施することができる。上記実施形態及び以下の変更例は、技術的に矛盾しない範囲で互いに組み合わせて実施することができる。 (Other embodiments)
The above embodiment can be modified and implemented as follows. The above-described embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
　・図６に示すように、弁８０，８１のうち弁８１の中心部に電線部材２０（図２参照）の挿通方向に貫通する貫通孔８６を形成するようにしてもよい。すなわち、弁８１の厚さ方向に貫通する貫通孔８６を弁８１の中心部に形成するようにしてもよい。貫通孔８６は、挿通領域８１Ｘの中心部に設けられている。すなわち、貫通孔８６は、その中心軸が挿通孔７８の中心軸Ａ１と一致するように形成されている。貫通孔８６の横断面形状は、電線部材２０の外形に対応する形状、ここでは円形状に形成されている。貫通孔８６の横断面形状の大きさは、電線部材２０の横断面形状よりも小さく形成されている。貫通孔８６は、分割弁８１Ａに形成された凹部８６Ａと、分割弁８１Ｂに形成された凹部８６Ｂとが分割筒部４０，５０の合体方向に重ね合わされて構成されている。 As shown in FIG. 6, a through hole 86 penetrating in the insertion direction of the electric wire member 20 (see FIG. 2) may be formed in the central portion of the valve 81 of the valves 80 and 81. That is, the through hole 86 penetrating in the thickness direction of the valve 81 may be formed in the central portion of the valve 81. The through hole 86 is provided at the center of the insertion area 81X. That is, the through hole 86 is formed so that its central axis coincides with the central axis A1 of the insertion hole 78. The cross-sectional shape of the through hole 86 is formed in a shape corresponding to the outer shape of the electric wire member 20, here, a circular shape. The size of the cross-sectional shape of the through hole 86 is smaller than that of the electric wire member 20. The through hole 86 is configured by stacking a recess 86A formed on the split valve 81A and a recess 86B formed on the split valve 81B in the direction in which the split cylindrical portions 40, 50 are combined.
　この構成によれば、電線部材２０がプロテクタ３２に挿通された場合の弁８１の変形する部分が短くなるため、電線部材２０の外周面に対する弁８１の追従性を向上させることができる。これにより、弁８１と電線部材２０との間に隙間が生じることを好適に抑制できる。 According to this configuration, the portion of the valve 81 that deforms when the electric wire member 20 is inserted into the protector 32 becomes shorter, so that the followability of the valve 81 to the outer peripheral surface of the electric wire member 20 can be improved. Accordingly, it is possible to preferably suppress the occurrence of a gap between the valve 81 and the electric wire member 20.
　また、弁８０，８１のうちプロテクタ３２の端面３２Ａから遠く離れた方の弁８１に貫通孔８６を形成した。すなわち、弁８０，８１のうちプロテクタ３２の内方側（つまり、内部空間側）に位置する弁８１に貫通孔８６を形成したため、プロテクタ３２の内方側に位置する弁８１の変形する部分を短くできる。これにより、弁８０，８１が電線部材２０の外周面に追従してプロテクタ３２の端面３２Ａ側（つまり、外方側）に倒れるように変形した場合に、プロテクタ３２の内方側に位置する弁８１がプロテクタ３２の外方側に位置する弁８０と電線部材２０の外周面との間に入り込むことを抑制できる。この結果、弁８０と電線部材２０の外周面との間に隙間が生じることを好適に抑制できる。 A through hole 86 is formed in the valve 81, which is farther from the end surface 32A of the protector 32, of the valves 80 and 81. That is, since the through hole 86 is formed in the valve 81 located on the inner side of the protector 32 (that is, on the inner space side) of the valves 80 and 81, the deformed portion of the valve 81 located on the inner side of the protector 32 is reduced. Can be shortened. Accordingly, when the valves 80 and 81 are deformed to follow the outer peripheral surface of the electric wire member 20 and fall toward the end surface 32A side (that is, the outer side) of the protector 32, the valve positioned on the inner side of the protector 32. It is possible to prevent 81 from entering between the valve 80 located on the outer side of the protector 32 and the outer peripheral surface of the electric wire member 20. As a result, it is possible to preferably suppress the formation of a gap between the valve 80 and the outer peripheral surface of the electric wire member 20.
　・図６に示した変更例では、弁８０，８１のうちプロテクタ３２の端面３２Ａから遠く離れた方の弁８１に貫通孔８６を形成したが、弁８０，８１のうち端面３２Ａに近い方の弁８０の中心部に電線部材２０の挿通方向に貫通する貫通孔を形成してもよい。この場合に、弁８０，８１のうち弁８０のみに貫通孔を形成してもよいし、弁８０，８１の双方に貫通孔を形成してもよい。 In the modified example shown in FIG. 6, the through hole 86 is formed in the valve 81, which is farther from the end surface 32A of the protector 32, of the valves 80, 81, but the valve 80, 81 is closer to the end surface 32A. A through hole that penetrates in the insertion direction of the electric wire member 20 may be formed in the central portion of the valve 80. In this case, the through hole may be formed only in the valve 80 among the valves 80 and 81, or the through hole may be formed in both the valves 80 and 81.
　・図６に示した変更例における貫通孔８６の横断面形状は、挿通される電線部材２０の横断面形状に対応する形状に設定される。このため、電線部材２０の横断面形状に合わせて貫通孔８６の横断面形状を適宜変更することができる。例えば電線部材２０の横断面形状が矩形状である場合には、貫通孔８６の横断面形状も矩形状に設定することができる。 The cross-sectional shape of the through hole 86 in the modification shown in FIG. 6 is set to a shape corresponding to the cross-sectional shape of the electric wire member 20 to be inserted. Therefore, the cross-sectional shape of the through hole 86 can be appropriately changed according to the cross-sectional shape of the electric wire member 20. For example, when the cross-sectional shape of the electric wire member 20 is rectangular, the cross-sectional shape of the through hole 86 can be set to be rectangular.
　・上記実施形態では、弁部材４２，５２を、プロテクタ３２の端面３２Ａからプロテクタ３２の内側に離間した位置に設けたが、その形成位置は特に限定されない。例えば、電線保持部７０Ａ，７０Ｂの端面７２Ａ，７２Ｂがプロテクタ３２の端面３２Ａと面一になるように、本体部４１，５１の内周面に弁部材４２，５２を設けるようにしてもよい。 In the above embodiment, the valve members 42 and 52 are provided at positions separated from the end surface 32A of the protector 32 to the inside of the protector 32, but the formation position thereof is not particularly limited. For example, the valve members 42 and 52 may be provided on the inner peripheral surfaces of the body portions 41 and 51 so that the end surfaces 72A and 72B of the wire holding portions 70A and 70B are flush with the end surface 32A of the protector 32.
　・あるいは、弁部材４２，５２を、プロテクタ３２の長さ方向の中央部における本体部４１，５１の内周面に設けるようにしてもよい。
　・上記実施形態では、プロテクタ３２の内部空間に、弁部材４２，５２によって構成される弁部材４３を１つ設けるようにしたが、その数は特に限定されない。例えば、プロテクタ３２の内部空間に、弁部材４３を２つ以上設けるようにしてもよい。例えば、弁部材４３を、プロテクタ３２の長さ方向の端面のうちコルゲートチューブ３３に近い端面、つまり車両前方側の端面の近傍にも設けるようにしてもよい。 -Alternatively, the valve members 42 and 52 may be provided on the inner peripheral surfaces of the body portions 41 and 51 at the central portion of the protector 32 in the longitudinal direction.
In the above embodiment, one valve member 43 including the valve members 42 and 52 is provided in the internal space of the protector 32, but the number is not particularly limited. For example, two or more valve members 43 may be provided in the internal space of the protector 32. For example, the valve member 43 may be provided on the end face of the protector 32 in the length direction near the end face near the corrugated tube 33, that is, near the end face on the vehicle front side.
　・上記実施形態では、プロテクタ３２の本体部４１，５１と一体に形成された弁部材４２，５２に具体化したが、これに限定されない。
　例えば図７に示すように、プロテクタ３２とは別部材であるホルダ１００に、プロテクタ３２の内周面と電線部材２０の外周面との間の隙間を塞ぐ弁部材４３を設けるようにしてもよい。ホルダ１００は、プロテクタ３２の端部の外周に嵌合される筒部１０１と、その筒部１０１の内周面に形成された弁部材４３とを有している。弁部材４３は、ホルダ１００の長さ方向に並んで設けられた２つの弁８０，８１を有している。換言すると、弁部材４３は、電線部材２０の挿通方向に並んで設けられた２つの弁８０，８１を有している。ホルダ１００は、例えば、電線部材２０が挿通された状態のプロテクタ３２の端部に装着される。このとき、ホルダ１００の内部に電線部材２０が挿通されることに伴って弁８０，８１が電線部材２０の外周面に沿って変形し、その変形した弁８０，８１によって、プロテクタ３２の内周面と電線部材２０の外周面との間の隙間が塞がれる。なお、ホルダ１００の弁部材４３が設けられた側の第１端部とその第１端部から導出された電線部材２０との間は、例えば、ホルダ１００の第１端部の外周と電線部材２０の外周とに亘って巻かれるテープ９６によって閉塞されている。また、ホルダ１００のプロテクタ３２に嵌合される側の第２端部とプロテクタ３２との間は、例えば、ホルダ１００の第２端部の外周とプロテクタ３２の外周とに亘って巻かれるテープ９７によって閉塞されている。 In the above embodiment, the valve members 42 and 52 formed integrally with the body portions 41 and 51 of the protector 32 are embodied, but the invention is not limited to this.
For example, as shown in FIG. 7, the holder 100, which is a member separate from the protector 32, may be provided with a valve member 43 that closes the gap between the inner peripheral surface of the protector 32 and the outer peripheral surface of the electric wire member 20. .. The holder 100 has a tubular portion 101 fitted to the outer circumference of the end of the protector 32, and a valve member 43 formed on the inner circumferential surface of the tubular portion 101. The valve member 43 has two valves 80 and 81 arranged side by side in the length direction of the holder 100. In other words, the valve member 43 has two valves 80 and 81 arranged side by side in the insertion direction of the electric wire member 20. The holder 100 is attached to, for example, the end portion of the protector 32 with the electric wire member 20 inserted therethrough. At this time, the valves 80 and 81 are deformed along the outer peripheral surface of the electric wire member 20 as the electric wire member 20 is inserted into the holder 100, and the deformed valves 80 and 81 cause the inner circumference of the protector 32 to be changed. The gap between the surface and the outer peripheral surface of the electric wire member 20 is closed. In addition, between the first end portion of the holder 100 on the side where the valve member 43 is provided and the electric wire member 20 led out from the first end portion, for example, the outer circumference of the first end portion of the holder 100 and the electric wire member. It is closed by a tape 96 wound around the outer circumference of 20. Further, between the second end portion of the holder 100 on the side fitted to the protector 32 and the protector 32, for example, the tape 97 wound around the outer circumference of the second end portion of the holder 100 and the outer circumference of the protector 32. Is blocked by.

For example, as shown in FIG. 8, the valve member 43 may be provided with only one valve 81. Like the valve 81 shown in FIG. 6, the valve 81 in this case preferably has a through hole 86 formed in the center thereof. When the through hole 86 is formed, the formation of the slits S3 and S4 can be omitted.
　・上記実施形態では、２つに分割された弁部材４２，５２を組み合わせて１つの弁部材４３を構成するようにしたが、これに限定されない。例えば、弁部材４３を、弁部材４２，５２を一体に形成した単一部品に変更してもよい。この場合には、例えば、電線保持部７０Ａ，７０Ｂ，７１Ａ，７１Ｂ及び土台部６０Ａ，６０Ｂが単一部品で構成され、弁８０，８１が単一部品で構成される。 In the above embodiment, the valve members 42 and 52 divided into two are combined to form one valve member 43, but the present invention is not limited to this. For example, the valve member 43 may be changed to a single component in which the valve members 42 and 52 are integrally formed. In this case, for example, the electric wire holding portions 70A, 70B, 71A, 71B and the base portions 60A, 60B are configured by a single component, and the valves 80, 81 are configured by a single component.
　・上記実施形態では、プロテクタ３２を、２つの分割筒部４０，５０を組み合わせて構成するようにしたが、これに限定されない。例えば、プロテクタ３２を、３つ以上の分割筒部を組み合わせて構成するようにしてもよい。 In the above embodiment, the protector 32 is configured by combining the two divided cylindrical portions 40 and 50, but the present invention is not limited to this.

For example, the valves 80 and 81 may be directly formed on the inner peripheral surfaces of the main body portions 41 and 51 of the split cylindrical portions 40 and 50. That is, the formation of the base portions 60A and 60B may be omitted.

　・上記実施形態では、電線部材２０の電線２１を１本としたが、電線２１の本数は特に限定されない。例えば、車両の仕様に応じて電線２１の本数は変更することができ、電線２１を２本以上としてもよい。例えば、ワイヤハーネス１０を構成する電線として、低圧バッテリと各種低電圧機器（例えば、ランプ、カーオーディオ等）とを接続する低圧電線を追加した構成としてもよい。 The electric wire holding portions 70A, 70B and the electric wire holding portions 71A, 71B in the above embodiment may be omitted.
-In the said embodiment, although the electric wire 21 of the electric wire member 20 was one, the number of the electric wires 21 is not specifically limited. For example, the number of the electric wires 21 can be changed according to the specifications of the vehicle, and the electric wires 21 may be two or more.

A plurality of slits S1 and S2 are formed in each insertion area 80X. Two electric wires 21 are individually inserted into each insertion area 80X.

　・上記実施形態における挿通領域８０Ｘ，８１Ｘは、電線部材２０の横断面形状に対応する形状に設定される。このため、電線部材２０の横断面形状に合わせて挿通領域８０Ｘ，８１Ｘの形状を適宜変更することができ、スリットＳ１～Ｓ４の形状を適宜変更することができる。例えば電線部材２０の横断面形状が矩形状である場合には、挿通領域８０Ｘ，８１Ｘも矩形状に設定することができる。 The insertion regions 80X and 81X in the above embodiment are set to have a shape corresponding to the cross-sectional shape of the electric wire member 20. Therefore, the shapes of the insertion regions 80X and 81X can be appropriately changed according to the cross-sectional shape of the electric wire member 20, and the shapes of the slits S1 to S4 can be appropriately changed. For example, when the cross-sectional shape of the electric wire member 20 is rectangular, the insertion regions 80X and 81X can also be set to be rectangular.
