Description

分岐ワイヤーハーネスBranch wire harness
　本明細書によって開示される技術は、分岐ワイヤーハーネスに関する。 The technology disclosed in this specification relates to a branch wire harness.
　複数の電線が束ねられた電線束を備え、電線束から、一部の電線の端末部が分岐している分岐ワイヤーハーネスが知られている。
　分岐ワイヤーハーネスを構成する電線の保護を目的として、電線束にテープを捲回したり、電線束を合成樹脂製の外装体によって包囲したりすることがある（特許文献１参照）。 2. Description of the Related Art A branch wire harness that includes an electric wire bundle in which a plurality of electric wires are bundled and from which the terminal portions of some electric wires are branched from the electric wire bundle is known.
For the purpose of protecting the electric wires constituting the branch wire harness, a tape may be wound around the electric wire bundle, or the electric wire bundle may be surrounded by a synthetic resin exterior body (see Patent Document 1).
特開２０１３－０２１７５３号公報JP 2013-021753 A
　電線束にテープを捲回する場合には、分岐している箇所でテープがほどけないように巻き付けるために手間がかかり、製造工程が煩雑化する。 When winding the tape around the wire bundle, it takes time to wind the tape so that the tape does not unwind at the branching point, and the manufacturing process becomes complicated.
　一方、電線束を外装体によって包囲する場合には、分岐線を導出できるように外装体を分割したり、外装体に切り欠きを設けたりする必要がある。このような構成では、外装体の加工に手間がかかり、製造工程が煩雑化する。また、輸送中や使用中において分岐ワイヤーハーネスに振動が加えられた場合に、外装体と電線とがぶつかり合ったりこすれあったりして、外装体の切り口によって電線の絶縁被覆が損傷するおそれがある。 On the other hand, when the wire bundle is surrounded by the exterior body, it is necessary to divide the exterior body so that the branch line can be derived or to provide a cutout in the exterior body. With such a configuration, it takes time to process the exterior body, and the manufacturing process becomes complicated. In addition, when vibration is applied to the branch wire harness during transportation or use, the outer body and the electric wire may collide or be rubbed, and the insulation of the electric wire may be damaged by the cut of the outer body. .
　本明細書によって開示される分岐ワイヤーハーネスは、芯線と、前記芯線を被覆する絶縁被覆とを備える電線により構成され、本線と、前記本線から分岐した分岐線とを備えるハーネス本体と、前記本線に装着される筒状の外装体とを備えた分岐ワイヤーハーネスであって、前記外装体が、軸方向に沿って延び、前記分岐線を外部に導出可能なスリットを有し、前記スリットを挟んで互いに対向して配置される一対のリップ部を備えるとともに、前記リップ部を除く部分がチューブ本体となっており、前記リップ部が前記チューブ本体よりも軟質な材料により構成されている。 The branch wire harness disclosed in the present specification is configured by an electric wire including a core wire and an insulating coating that covers the core wire, and includes a harness main body including a main wire and a branch wire branched from the main wire, and the main wire. A branch wire harness having a cylindrical outer body to be mounted, the outer body having a slit that extends along an axial direction and that can lead out the branch line to the outside. While having a pair of lip | rip parts arrange | positioned facing each other, the part except the said lip | rip part becomes a tube main body, and the said lip | rip part is comprised with the softer material than the said tube main body.
　上記の構成によれば、一対のリップ部によって、分岐線を柔らかく挟むようにして保持しつつ、本線を包囲する外装体から引き出すことができる。また、外装体が分岐線を挟んで保持していることにより、分岐ワイヤーハーネスの輸送中や使用中において、振動が加えられた場合に、ハーネス本体と外装体とが同位相で振動することとなり、外装体とハーネス本体とのぶつかり合い、こすれ合いをある程度抑制することができる。これらにより、外装体とハーネス本体とがぶつかり合ったり、こすれ合ったりすることによって絶縁被覆が損傷することを回避できる。また、所望の箇所で分岐線を引き出して一対のリップ部によって保持させれば足りるため、製造工程を簡素化できる。 According to the above configuration, the pair of lip portions can be pulled out from the exterior body surrounding the main line while holding the branch line so as to be sandwiched softly. In addition, because the exterior body holds the branch wire across it, the harness body and the exterior body vibrate in the same phase when vibration is applied during transportation or use of the branch wire harness. The collision and rubbing between the exterior body and the harness body can be suppressed to some extent. Accordingly, it is possible to avoid damage to the insulation coating due to collision or rubbing between the exterior body and the harness body. Further, since it is sufficient to draw the branch line at a desired location and hold it by the pair of lip portions, the manufacturing process can be simplified.
　上記の構成において、前記リップ部が、前記絶縁被覆より軟質な材料により構成されていても構わない。
　このような構成によれば、絶縁被覆の損傷を確実に回避できる。 Said structure WHEREIN: The said lip | rip part may be comprised with the softer material than the said insulation coating.
According to such a configuration, damage to the insulation coating can be reliably avoided.
　上記の構成において、前記一対のリップ部のそれぞれが、相手側のリップ部と対向するリップ面を有しており、一対の前記リップ面間の距離が、前記分岐線の外径よりも小さくなっていても構わない。
　このような構成によれば、一対のリップ部による分岐線の保持力を確保することができる。 In the above configuration, each of the pair of lip portions has a lip surface facing the counterpart lip portion, and a distance between the pair of lip surfaces is smaller than an outer diameter of the branch line. It does not matter.
According to such a structure, the retention strength of the branch line by a pair of lip | rip parts can be ensured.
　上記の構成において、前記リップ部の幅が前記分岐線の外径よりも大きくなっていても構わない。
　このような構成によれば、分岐線との摩擦などによりリップ部が削れたとしても、分岐線がチューブ本体に当接しない。これにより、硬いチューブ本体が分岐線に当接して絶縁被覆が損傷することを回避できる。 Said structure WHEREIN: The width | variety of the said lip | rip part may be larger than the outer diameter of the said branch line.
According to such a configuration, even if the lip portion is scraped due to friction with the branch line or the like, the branch line does not contact the tube body. Thereby, it can avoid that a hard tube main body contact | abuts a branch line and an insulation coating is damaged.
　上記の構成において、前記一対のリップ部のそれぞれが、相手側のリップ部と対向するリップ面を有しており、一対の前記リップ面のそれぞれが、相手側のリップ面に向かって凸となる曲面となっていても構わない。
　このようにリップ面、すなわち分岐線に当接する面が曲面となっており、鋭利な角部を有していないことによって、絶縁被覆の損傷を確実に回避できる。 In the above configuration, each of the pair of lip portions has a lip surface facing the counterpart lip portion, and each of the pair of lip surfaces is convex toward the counterpart lip surface. It may be a curved surface.
As described above, the lip surface, that is, the surface in contact with the branch line is a curved surface and has no sharp corners, so that damage to the insulating coating can be avoided reliably.
　本明細書によって開示される技術によれば、簡素な製造工程で、絶縁被覆の損傷を回避できる分岐ワイヤーハーネスを提供できる。 According to the technique disclosed in this specification, it is possible to provide a branch wire harness that can avoid damage to the insulation coating with a simple manufacturing process.

　実施形態を、図１～図４を参照しつつ説明する。本実施形態の分岐ワイヤーハーネス１は、図１に示すように、複数の電線１１により構成されるハーネス本体１０と、このハーネス本体１０に装着される外装体２０とを備えている。各電線１１は、芯線１２と、この芯線１２の外周を被覆する合成樹脂製の絶縁被覆１３とを備える公知の構成のものである。複数の電線１１は束ねられて電線束１１Ｂ（本線に該当）とされ、電線束１１Ｂからは、各電線１１の端末部１１Ｅ（分岐線に該当）が分岐している。 Embodiments will be described with reference to FIGS. The branch wire harness 1 of this embodiment is provided with the harness main body 10 comprised by the some electric wire 11, and the exterior body 20 with which this harness main body 10 is mounted | worn as shown in FIG. Each electric wire 11 has a known configuration including a core wire 12 and an insulating coating 13 made of synthetic resin that covers the outer periphery of the core wire 12. The plurality of electric wires 11 are bundled into an electric wire bundle 11B (corresponding to the main line), and the terminal portions 11E of the electric wires 11 (corresponding to branch lines) are branched from the electric wire bundle 11B.
　外装体２０は、合成樹脂製であって、図１に示すように、全体として、両端が開口した円筒状に構成されている。この外装体２０は、軸方向に沿って全長にわたって延びるスリット２１を有しており、このスリット２１から各電線１１の端末部１１Ｅが外装体２０の外部に導出されている。 The exterior body 20 is made of a synthetic resin, and as illustrated in FIG. 1, the exterior body 20 is configured in a cylindrical shape having both ends opened as a whole. The exterior body 20 has a slit 21 extending over the entire length along the axial direction, and the terminal portion 11E of each electric wire 11 is led out of the exterior body 20 from the slit 21.
　外装体２０は、一対のリップ部２２、２２を備えている。一対のリップ部２２、２２は、図３に示すように、外装体２０において、スリット２１の両側に、スリット２１に隣接して、互いに対向して配置されている。一対のリップ部２２、２２のそれぞれは、スリット２１に沿って、外装体２０の全長にわたって延びる細長い帯状の部分である。外装体２０において、これら一対のリップ部２２、２２を除く部分は、チューブ本体２３となっている。 The exterior body 20 includes a pair of lip portions 22 and 22. As shown in FIG. 3, the pair of lip portions 22, 22 are disposed on both sides of the slit 21 in the exterior body 20, adjacent to the slit 21 and facing each other. Each of the pair of lip portions 22, 22 is an elongated belt-like portion extending along the slit 21 over the entire length of the exterior body 20. In the exterior body 20, a portion excluding the pair of lip portions 22 and 22 is a tube main body 23.
　各リップ部２２は、チューブ本体２３よりも軟質であり、かつ、電線１１の絶縁被覆１３より軟質な材料により構成されている。例えば、チューブ本体２３および絶縁被覆１３がポリプロピレンまたは硬質ＰＶＣ（ポリ塩化ビニル）により構成されており、リップ部２２がエラストマまたは軟質ＰＶＣ（ポリ塩化ビニル）により構成されていてもよい。 Each lip portion 22 is made of a material that is softer than the tube body 23 and softer than the insulating coating 13 of the electric wire 11. For example, the tube body 23 and the insulating coating 13 may be made of polypropylene or hard PVC (polyvinyl chloride), and the lip portion 22 may be made of elastomer or soft PVC (polyvinyl chloride).
　一対のリップ部２２、２２のそれぞれにおいて、相手側のリップ部２２と対向する面（リップ面２２Ｆ）は、図４に示すように、相手側のリップ面２２Ｆに向かって凸となる曲面となっている。また、各リップ部２２の幅（リップ面２２Ｆからその反対側の端縁までの距離）Ｗは、電線１１の外径Ｄ１よりも大きくなっている。
　外装体２０が電線束１１Ｂに外装されていない状態においては、一対のリップ部２２、２２が互いに接触している。 In each of the pair of lip portions 22, 22, the surface (lip surface 22 </ b> F) facing the mating lip portion 22 is a curved surface that is convex toward the mating lip surface 22 </ b> F, as shown in FIG. 4. ing. Further, the width (distance from the lip surface 22F to the opposite end edge) W of each lip portion 22 is larger than the outer diameter D1 of the electric wire 11.
In a state where the outer package 20 is not covered by the wire bundle 11B, the pair of lip portions 22 and 22 are in contact with each other.
　上記のような外装体２０は、例えば二色成形によって製造することができる。 The exterior body 20 as described above can be manufactured by, for example, two-color molding.
　外装体２０は、電線束１１Ｂを包囲するように装着され、一対のリップ部２２、２２の間から、各電線１１の端末部１１Ｅが外部に引き出されている。一対のリップ部２２、２２は、電線１１が間に通されることによって圧縮され、弾性復元力によって、端末部１１Ｅを両側から挟み付けるようにして、端末部１１Ｅの外周に密着する。これにより、端末部１１Ｅが所望の位置で保持される。一対のリップ部２２、２２は、端末部１１Ｅが導出されている箇所を除く部分では、互いに密着している。 The exterior body 20 is mounted so as to surround the wire bundle 11 </ b> B, and the terminal portion 11 </ b> E of each wire 11 is drawn out from between the pair of lip portions 22 and 22. The pair of lip portions 22 and 22 are compressed when the electric wire 11 is passed between them, and are brought into close contact with the outer periphery of the terminal portion 11E so as to sandwich the terminal portion 11E from both sides by elastic restoring force. Thereby, the terminal unit 11E is held at a desired position. The pair of lip portions 22 and 22 are in close contact with each other at portions other than the portion where the terminal portion 11E is led out.
　以上のように本実施形態によれば、分岐ワイヤーハーネス１は、ハーネス本体１０と、外装体２０とを備えている。ハーネス本体１０は、芯線１２と、芯線１２を被覆する絶縁被覆１３とを備える複数の電線１１により構成されている。複数の電線１１は束ねられて電線束１１Ｂとされ、電線束１１Ｂからは、各電線１１の端末部１１Ｅがそれぞれ分岐している。外装体２０は、電線束１１Ｂに外装されている。外装体２０が、軸方向に沿って延び、端末部１１Ｅを外部に導出可能なスリット２１を有し、このスリット２１を挟んで互いに対向して配置される一対のリップ部２２、２２を備えるとともに、一対のリップ部２２、２２を除く部分がチューブ本体２３となっており、リップ部２２、２２がチューブ本体２３よりも軟質な材料により構成されている。 As described above, according to the present embodiment, the branch wire harness 1 includes the harness body 10 and the exterior body 20. The harness body 10 includes a plurality of electric wires 11 including a core wire 12 and an insulating coating 13 that covers the core wire 12. The plurality of electric wires 11 are bundled into an electric wire bundle 11B, and the terminal portions 11E of the electric wires 11 are branched from the electric wire bundle 11B. The exterior body 20 is exteriorized by the wire bundle 11B. The exterior body 20 includes a pair of lip portions 22, 22 that extend along the axial direction and have a slit 21 that can lead out the terminal portion 11 </ b> E to the outside, and are opposed to each other across the slit 21. The portion excluding the pair of lip portions 22 and 22 is a tube body 23, and the lip portions 22 and 22 are made of a softer material than the tube body 23.
　上記の構成によれば、一対のリップ部２２、２２によって、電線１１の端末部１１Ｅを柔らかく挟むようにして保持しつつ、電線束１１Ｂを包囲する外装体２０から引き出すことができる。また、外装体２０が端末部１１Ｅを挟んで保持していることにより、分岐ワイヤーハーネス１の輸送中や使用中において、振動が加えられた場合に、ハーネス本体１０と外装体２０とが同位相で振動することとなり、外装体２０とハーネス本体１０とのぶつかり合い、こすれ合いをある程度抑制することができる。これらにより、外装体とハーネス本体とがぶつかり合ったり、こすれ合ったりすることによって絶縁被覆が損傷することを回避できる。また、所望の箇所で端末部１１Ｅを引き出して一対のリップ部２２、２２によって保持させれば足りるため、製造工程を簡素化できる。 According to the above configuration, the pair of lip portions 22 and 22 can be pulled out from the outer package 20 surrounding the wire bundle 11B while holding the terminal portion 11E of the wire 11 so as to be softly sandwiched. In addition, since the exterior body 20 holds the terminal portion 11E between the harness body 10 and the exterior body 20 when vibration is applied during transportation or use of the branch wire harness 1, the exterior body 20 is in phase. Therefore, the collision and rubbing between the exterior body 20 and the harness body 10 can be suppressed to some extent. Accordingly, it is possible to avoid damage to the insulation coating due to collision or rubbing between the exterior body and the harness body. Moreover, since it is sufficient to pull out the terminal portion 11E at a desired location and hold it by the pair of lip portions 22 and 22, the manufacturing process can be simplified.
　また、リップ部２２、２２が、絶縁被覆１３より軟質な材料により構成されている。このような構成によれば、絶縁被覆１３の損傷を確実に回避できる。 Further, the lip portions 22 and 22 are made of a material softer than the insulating coating 13. According to such a configuration, damage to the insulating coating 13 can be reliably avoided.
　また、一対のリップ部２２、２２のそれぞれが、相手側のリップ部２２と対向するリップ面２２Ｆを有しており、一対のリップ面２２Ｆ、２２Ｆ間の距離が、電線１１の外径よりも小さくなっている。このような構成によれば、一対のリップ部２２、２２による端末部１１Ｅの保持力を確保することができる。 Each of the pair of lip portions 22, 22 has a lip surface 22 </ b> F facing the counterpart lip portion 22, and the distance between the pair of lip surfaces 22 </ b> F, 22 </ b> F is larger than the outer diameter of the electric wire 11. It is getting smaller. According to such a configuration, the holding force of the terminal portion 11E by the pair of lip portions 22 and 22 can be ensured.
　さらに、一対のリップ部２２、２２のそれぞれは、電線１１の外径Ｄ１よりも大きな幅Ｗを有している。このような構成によれば、端末部１１Ｅとの摩擦などによりリップ部２２、２２が削れたとしても、端末部１１Ｅがチューブ本体２３に当接しない。これにより、硬いチューブ本体２３が端末部１１Ｅに当接して絶縁被覆１３が損傷することを回避できる。 Furthermore, each of the pair of lip portions 22 and 22 has a width W larger than the outer diameter D1 of the electric wire 11. According to such a configuration, even if the lip portions 22 and 22 are scraped due to friction with the terminal portion 11E, the terminal portion 11E does not contact the tube body 23. Thereby, it can avoid that the hard tube main body 23 contact | abuts to the terminal part 11E, and the insulation coating 13 is damaged.
　加えて、一対のリップ面２２Ｆ、２２Ｆのそれぞれが、相手側のリップ面２２Ｆに向かって凸となる曲面となっている。このように、リップ面２２Ｆ、すなわち端末部１１Ｅに当接する面が曲面となっており、鋭利な角部を有していないことによって、絶縁被覆１３の損傷を確実に回避できる。 In addition, each of the pair of lip surfaces 22F, 22F is a curved surface that is convex toward the mating lip surface 22F. Thus, the lip surface 22F, that is, the surface in contact with the terminal portion 11E is a curved surface and has no sharp corners, so that damage to the insulating coating 13 can be reliably avoided.
　＜変形例＞
　図５および図６に示すように、変形例の分岐ワイヤーハーネス３０は、実施形態と同様に、ハーネス本体１０と、このハーネス本体１０に装着され、スリット３２を有する外装体３１とを備えている。本変形例は、外装体３１の一対のリップ部３３、３３が互いに密着しておらず、互いに対向するリップ面３３Ｆ、３３Ｆの間に隙間を有している点で実施形態と異なる。 <Modification>
As shown in FIGS. 5 and 6, the branch wire harness 30 of the modified example includes a harness body 10 and an exterior body 31 that is attached to the harness body 10 and has a slit 32, as in the embodiment. . This modified example is different from the embodiment in that the pair of lip portions 33 and 33 of the exterior body 31 are not in close contact with each other and a gap is provided between the lip surfaces 33F and 33F facing each other.
　外装体３１が電線束１１Ｂに外装されていない状態においては、一対のリップ面３３Ｆ、３３Ｆの間隔Ｄ２が、電線１１の外径Ｄ１よりも小さくなっている。 In a state where the outer package 31 is not covered with the wire bundle 11B, the distance D2 between the pair of lip surfaces 33F and 33F is smaller than the outer diameter D1 of the wire 11.
　外装体３１が電線束１１Ｂに外装された状態では、一対のリップ部３３、３３の間から、各電線１１の端末部１１Ｅが外部に引き出されている。一対のリップ部３３、３３は、電線１１が間に通されることによって圧縮され、弾性復元力によって、端末部１１Ｅを両側から挟み付けるようにして、端末部１１Ｅの外周に密着する。これにより、端末部１１Ｅが所望の位置で保持される。一対のリップ部３３、３３は、端末部１１Ｅが導出されている箇所を除く部分では、一対のリップ面３３Ｆ、３３Ｆの間隔Ｄ２が、電線１１の外径Ｄ１よりも小さくなっている。 In the state where the exterior body 31 is externally covered with the wire bundle 11B, the terminal portion 11E of each wire 11 is drawn out from between the pair of lip portions 33 and 33. The pair of lip portions 33 and 33 are compressed when the electric wire 11 is passed between them, and are brought into close contact with the outer periphery of the terminal portion 11E so as to sandwich the terminal portion 11E from both sides by elastic restoring force. Thereby, the terminal unit 11E is held at a desired position. In the pair of lip portions 33 and 33, the distance D2 between the pair of lip surfaces 33 </ b> F and 33 </ b> F is smaller than the outer diameter D <b> 1 of the electric wire 11 except for the portion where the terminal portion 11 </ b> E is led out.
　本変形例において、上記以外の構成は、実施形態と同様であり、同様の構成には同一の符号を付して説明を省略する。 In the present modification, configurations other than those described above are the same as those in the embodiment, and the same configurations are denoted by the same reference numerals and description thereof is omitted.
