Description

ワイヤハーネスプロテクタWire harness protector
　本発明は、自動車等の車両の外面に配索されるワイヤハーネスを保護するためのワイヤハーネスプロテクタに関する。 The present invention relates to a wire harness protector for protecting a wire harness routed on the outer surface of a vehicle such as an automobile.
　近年、環境への配慮や省エネルギー化が望まれており、モータとエンジンとによって駆動されるハイブリッド自動車、および、モータによって駆動される電気自動車が注目されている。 In recent years, environmental considerations and energy savings have been desired, and hybrid vehicles driven by a motor and an engine and electric vehicles driven by a motor are attracting attention.
　ハイブリッド自動車および電気自動車には、電力を供給するためのバッテリと、該バッテリから出力された直流電流を所定の周波数の高圧交流電流（三相交流電流）に変換するインバータと、該インバータから出力された高圧交流電流によって駆動されるモータと、が搭載され、前記インバータと前記モータとが三相交流高圧ハーネス（ワイヤハーネス）によって電気的に接続されている。 Hybrid vehicles and electric vehicles include a battery for supplying electric power, an inverter that converts a direct current output from the battery into a high-voltage alternating current (three-phase alternating current) having a predetermined frequency, and an output from the inverter. And a motor driven by a high-voltage AC current, and the inverter and the motor are electrically connected by a three-phase AC high-voltage harness (wire harness).
　また、ハイブリッド自動車および電気自動車では、一例として、インバータは車両後方に配置されているとともにモータは車両前方には位置されていることから、車両のフロアパネルの地面側（車両外面）となる床下にワイヤハーネスが配索され、該ワイヤハーネスが、フロアパネルの床下の形状および配索経路に沿って三次元形状に形成されている。 Moreover, in hybrid vehicles and electric vehicles, as an example, the inverter is arranged at the rear of the vehicle and the motor is located at the front of the vehicle. Therefore, the hybrid vehicle and the electric vehicle are below the floor on the ground side (vehicle outer surface) of the vehicle floor panel. A wire harness is routed, and the wire harness is formed in a three-dimensional shape along the underfloor shape of the floor panel and the routing route.
　また、ワイヤハーネスがフロアパネルの床下に配索されることから、飛び石等からワイヤハーネスを保護するためのワイヤハーネスプロテクタに収容されている。 Also, since the wire harness is routed under the floor panel, it is housed in a wire harness protector for protecting the wire harness from stepping stones.
　このようなワイヤハーネスプロテクタとしては、堅い剛性部材で構成された成形プロテクタ等（例えば、特許文献１および特許文献２など参照）、および、柔らかい可撓性部材で構成されたコルゲートチューブ等（例えば、特許文献３および特許文献４など参照）が広く知られている。 As such a wire harness protector, a molded protector or the like made of a rigid member (see, for example, Patent Document 1 and Patent Document 2), a corrugated tube made of a soft flexible member, or the like (for example, Patent Document 3 and Patent Document 4) are widely known.
特開２０００－２２４７２９号公報JP 2000-224729 A 特開平８－３４０６１６号公報JP-A-8-340616 特開２００７－１７７８１０号公報JP 2007-177810 A 特開平１０－３０４５３１号公報Japanese Patent Laid-Open No. 10-304531
　しかしながら、前述した特許文献１または特許文献２などに示された従来のワイヤハーネスプロテクタは、車両後方から車両前方に亘って配索されるワイヤハーネスの配索形態に沿った三次元形状に形成されるとともに、車両後方から車両前方までの長尺に形成されており、また、剛性部材で構成されることから、ワイヤハーネスプロテクタおよびワイヤハーネス等の組立工場からハイブリッド自動車や電気自動車等の組立工場に運搬する際に、屈曲させることができないため、運搬時に長尺で大きい梱包箱を必要とし、積荷の嵩密度が大幅に低下することとなり、運搬効率が低下してしまうという問題があった。 However, the conventional wire harness protector shown in Patent Document 1 or Patent Document 2 described above is formed in a three-dimensional shape along the wiring form of the wire harness that is routed from the rear of the vehicle to the front of the vehicle. In addition, since it is formed in a long length from the rear of the vehicle to the front of the vehicle and is composed of a rigid member, it is changed from an assembly plant for wire harness protectors and wire harnesses to an assembly plant for hybrid vehicles and electric vehicles. Since it cannot be bent when transported, a long and large packing box is required during transport, and the bulk density of the load is greatly reduced, resulting in a problem of reduced transport efficiency.
　また、積荷の嵩密度を少しでも高めるために、運搬時に梱包しないことも考えられるが、運搬時における振動や衝撃などに対するワイヤハーネスプロテクタへの保護が不十分となってしまう虞がある。 Also, in order to increase the bulk density of the load as much as possible, it may be possible not to pack it during transportation, but there is a risk that protection to the wire harness protector against vibration or impact during transportation will be insufficient.
　また、前述した特許文献３または特許文献４などに示された従来のワイヤハーネスプロテクタは、容易に屈曲させることができるため、運搬時の梱包が容易となるとともに運搬効率の低下を抑えることができるが、ハイブリッド自動車や電気自動車等の組立工場において車両のフロアパネルにワイヤハーネスプロテクタを搭載する際に、ワイヤハーネスプロテクタをワイヤハーネスの配索経路に沿って変形させながらフロアパネルに取り付けなければならず、作業効率の向上には限度があるという問題があった。 Moreover, since the conventional wire harness protector shown by patent document 3 or patent document 4 mentioned above can be bent easily, the packaging at the time of conveyance becomes easy and the fall of conveyance efficiency can be suppressed. However, when mounting a wire harness protector on a vehicle floor panel in an assembly plant such as a hybrid vehicle or an electric vehicle, the wire harness protector must be attached to the floor panel while being deformed along the wiring route of the wire harness. There is a problem that there is a limit to the improvement of work efficiency.
　また、ワイヤハーネスプロテクタが容易に屈曲されるため、車両のフロアパネルへの搭載時に、ワイヤハーネスの配索経路を細かく（すなわち精密に）規制することが困難であるという問題があった。 Also, since the wire harness protector is easily bent, there is a problem that it is difficult to finely (that is, precisely) regulate the wiring route of the wire harness when mounted on the floor panel of the vehicle.
　また、ワイヤハーネスプロテクタの機械的強度が成形プロテクタよりも低いため、ワイヤハーネスの保護性能が劣るという問題があった。 Also, since the mechanical strength of the wire harness protector is lower than that of the molded protector, there is a problem that the protection performance of the wire harness is inferior.
　本発明は、かかる問題を解決することを目的とするものである。即ち、本発明は、運搬時にはコンパクト形態となり、車両への搭載時にはワイヤハーネスの配索形態となり、ワイヤハーネスの保護性能の優れたワイヤハーネスプロテクタを提供することを目的とする。 The present invention aims to solve such problems. That is, an object of the present invention is to provide a wire harness protector that has a compact form during transportation and a wire harness arrangement form when mounted on a vehicle, and has excellent protection performance of the wire harness.

　第１保護部材２の一端部８には、図２および図３に示すように、第３保護部材４の一端部２７と係合する第１係合部１２と、第３保護部材４の一端部２７が収容される第１収容部１０と、後述する第１カバー（図４（Ａ）参照）３４と係合する係合突起９と、が設けられている。 As shown in FIGS. 2 and 3, one end portion 8 of the first protection member 2 is engaged with one end portion 27 of the third protection member 4 and one end of the third protection member 4. A first accommodating portion 10 in which the portion 27 is accommodated, and an engaging protrusion 9 that engages with a first cover (see FIG. 4A) 34 to be described later are provided.
　第１係合部１２は、図３に示すように、後述する第３保護部材４の大径部（図２参照）３１の外周面に対応した内径となるように内周面を拡径させた第１周壁部６の内周面に設けられている。第１係合部１２は、複数個（図示例では、３個）設けられている。第１係合部１２は、第１周壁部６の内周面から突出されるとともに該内周面の周方向に延在された突条とされている。 As shown in FIG. 3, the first engaging portion 12 has an inner peripheral surface whose diameter is increased so as to have an inner diameter corresponding to an outer peripheral surface of a large-diameter portion (see FIG. 2) 31 of the third protective member 4 described later. Further, the first peripheral wall portion 6 is provided on the inner peripheral surface. A plurality (three in the illustrated example) of first engaging portions 12 are provided. The first engaging portion 12 is a protrusion that protrudes from the inner peripheral surface of the first peripheral wall portion 6 and extends in the circumferential direction of the inner peripheral surface.
　第１係合部１２は、第３保護部材４の隣接する大径部３１同士の間に係合される幅に設定されているとともに、第３保護部材４の小径部（図２参照）３２と係合する突出量に設定されている。 The first engaging portion 12 is set to a width that is engaged between adjacent large-diameter portions 31 of the third protective member 4, and a small-diameter portion 32 of the third protective member 4 (see FIG. 2). The amount of protrusion is set to engage.
　このため、第１係合部１２と第３保護部材４とが確実に係合され、第１係合部１２と第３保護部材４との位置ズレが確実に規制されるので、第１保護部材２と第３保護部材４との長手方向の位置ズレ（移動）を規制した状態で、前記第１保護部材２と第３保護部材４とを連結して固定することができる。 For this reason, since the 1st engagement part 12 and the 3rd protection member 4 are engaged reliably, and position shift with the 1st engagement part 12 and the 3rd protection member 4 is controlled reliably, the 1st protection The first protective member 2 and the third protective member 4 can be connected and fixed in a state where the positional deviation (movement) in the longitudinal direction between the member 2 and the third protective member 4 is restricted.
　第１収容部１０は、図２および図３に示すように、上面が開口された断面Ｕ字形状の半円形状に形成されている。第１収容部１０は、その内径が、第３保護部材４の大径部３１の外周面よりも大径であり、後述する第２保護部材３の第２収容部２０の外周面よりも大径に形成されている。 As shown in FIG. 2 and FIG. 3, the first housing portion 10 is formed in a semicircular shape having a U-shaped cross section with an upper surface opened. The inner diameter of the first accommodating portion 10 is larger than the outer peripheral surface of the large diameter portion 31 of the third protective member 4 and is larger than the outer peripheral surface of the second accommodating portion 20 of the second protective member 3 described later. It is formed in the diameter.
　また、第１収容部１０は、図３に示すように、第１周壁部６の延在方向に延長されており、前記収容部１０と、第２保護部材３の第２収容部２０の先端部分とが、重なり範囲Ｄで重なるように延長量が設定されている。 Moreover, the 1st accommodating part 10 is extended in the extension direction of the 1st surrounding wall part 6, as shown in FIG. 3, The front-end | tip of the said accommodating part 10 and the 2nd accommodating part 20 of the 2nd protection member 3 is shown. The extension amount is set so that the portion overlaps in the overlapping range D.
　すなわち、第１収容部１０は、第３保護部材４の一端部２７が収容可能に形成されているとともに、第２保護部材３の第２収容部２０の先端部分が収容可能に形成され、第１収容部１０と第２収容部２０の先端部分とが重ね合わされるように形成されている。 That is, the first accommodating portion 10 is formed so that the one end portion 27 of the third protective member 4 can be accommodated, and the distal end portion of the second accommodating portion 20 of the second protective member 3 is configured to be accommodated. The first accommodating portion 10 and the distal end portion of the second accommodating portion 20 are formed so as to overlap each other.
　このように、第１収容部１０と第２収容部２０の先端部分とが重なり合うことから、前記第１収容部１０と第２収容部２０の先端部分との重なり部分で第３保護部材４が覆われるので、該第３保護部材４に収容されるワイヤハーネスを十分に保護することができる。 Thus, since the first storage portion 10 and the tip portion of the second storage portion 20 overlap, the third protective member 4 is at the overlap portion between the first storage portion 10 and the tip portion of the second storage portion 20. Since it is covered, the wire harness accommodated in the third protection member 4 can be sufficiently protected.
　また、第１収容部１０は、上面が開口された断面Ｕ字形状であることから、開口された上面から可撓性の第３保護部材４の屈曲箇所を外部に露出させて逃がすことができるようになるので、前記第３保護部材４を屈曲変形させることができるようになる。 Moreover, since the 1st accommodating part 10 is U-shaped cross-section by which the upper surface was opened, the bending location of the flexible 3rd protection member 4 can be exposed outside from the opened upper surface, and it can escape. As a result, the third protective member 4 can be bent and deformed.
　このため、第３保護部材４を屈曲変形させることによって、ワイヤハーネスプロテクタを運搬時などにおけるコンパクト形態に変形させることができるようになる。 For this reason, by bending and deforming the third protective member 4, the wire harness protector can be deformed into a compact form during transportation.
　重なり範囲Ｄは、図４（Ｂ）に示すように、例えば、梱包時において、後述する第３保護部材４を矢印ａ方向に屈曲させた際、および、車両への搭載時において、第３保護部材４を矢印ｂ方向に伸展させた際に、第１収容部１０と第２収容部２０とが互いに干渉しない範囲に設定されている。 As shown in FIG. 4B, the overlapping range D is, for example, a third protection when a third protection member 4 (to be described later) is bent in the direction of arrow a during packaging and when mounted on a vehicle. When the member 4 is extended in the direction of the arrow b, the first accommodating portion 10 and the second accommodating portion 20 are set in a range that does not interfere with each other.
　また、第１収容部１０には、車両のフロアパネルの床下に第１保護部材２を固定するための取付部３８が設けられている。 In addition, the first accommodating portion 10 is provided with an attachment portion 38 for fixing the first protective member 2 under the floor of the vehicle floor panel.
　取付部３８には、車両のフロアパネルの床下の取付座に対して締結されるボルト等の締結部材の挿通されるボルト孔３９が設けられている。 The mounting portion 38 is provided with a bolt hole 39 through which a fastening member such as a bolt fastened to a mounting seat under the floor of the vehicle floor panel is inserted.
　ボルト孔３９は、第１保護部材２の長手方向に長尺となる楕円形状に形成されている。ボルト孔３９は、例えば、インサート成形によって、第１保護部材２の取付部３８と、楕円形状の開口を有する金属とが一体化されて形成されている。 The bolt hole 39 is formed in an elliptical shape that is long in the longitudinal direction of the first protective member 2. The bolt hole 39 is formed, for example, by integrating the mounting portion 38 of the first protective member 2 and a metal having an elliptical opening by insert molding.
　このように、ボルト孔３９が第１保護部材２の長手方向に長尺となる楕円形状に形成されているので、車両のフロアパネルの床下に第１保護部材２を搭載する際に、該第１保護部材２の取付位置を微調整することができる。 Thus, since the bolt hole 39 is formed in an elliptical shape that is elongated in the longitudinal direction of the first protective member 2, the first protective member 2 is mounted when the first protective member 2 is mounted under the floor of a vehicle floor panel. 1 The attachment position of the protection member 2 can be finely adjusted.
　なお、他の取付部（図１参照）３６，４０、および、後述する第２カバー３５の取付部（不図示）も、前記取付部３８と同様に形成されている。 The other attachment portions (see FIG. 1) 36 and 40 and the attachment portion (not shown) of the second cover 35 described later are also formed in the same manner as the attachment portion 38.
　係合突起９は、図３に示すように、第１係合部１２の形成された箇所の第１周壁部６の外周面に設けられている。係合突起９は、前記外周面から突出され、第１カバー（図４（Ａ）参照）３４と係合可能に形成されている。 As shown in FIG. 3, the engagement protrusion 9 is provided on the outer peripheral surface of the first peripheral wall portion 6 where the first engagement portion 12 is formed. The engagement protrusion 9 protrudes from the outer peripheral surface and is formed to be able to engage with a first cover (see FIG. 4A) 34.
　第１カバー３４は、図４（Ａ）および図４（Ｂ）に示すように、配索形態に沿って延在された第１周壁部６の上面の開口を塞ぐように形成されている。また、第１カバー３４は、第１周壁部６に設けられた図示しない複数個の係合突起によって、前記第１周壁部６に係合されるように形成されている。 As shown in FIGS. 4A and 4B, the first cover 34 is formed so as to close the opening on the upper surface of the first peripheral wall portion 6 extending along the routing form. The first cover 34 is formed so as to be engaged with the first peripheral wall portion 6 by a plurality of engagement protrusions (not shown) provided on the first peripheral wall portion 6.
　また、第１カバー３４は、第１保護部材２の一端部８と、該一端部８の係合部（図３参照）１２に係合された第３保護部材４の一端部（図２参照）２７と、を覆うように形成されている。また、第１カバー３４の内周面には、前記第３保護部材４の一端部２７と係合する図示しない係合部が設けられている。 The first cover 34 has one end portion 8 of the first protection member 2 and one end portion of the third protection member 4 engaged with the engagement portion (see FIG. 3) 12 of the one end portion 8 (see FIG. 2). 27). Further, an engagement portion (not shown) that engages with the one end portion 27 of the third protection member 4 is provided on the inner peripheral surface of the first cover 34.
　なお、第１カバー３４を第１保護部材２に取り付けない場合であっても、第１周壁部６の開口された上面と車両のフロアパネルの床下とを対向させてワイヤハーネスプロテクタ１が搭載されるので、該ワイヤハーネスプロテクタ１に収容されたワイヤハーネスが直接外部に触れることはなく、飛び石等からワイヤハーネスを十分に保護することができる。 Even when the first cover 34 is not attached to the first protective member 2, the wire harness protector 1 is mounted with the upper surface of the first peripheral wall portion 6 and the under floor of the floor panel of the vehicle facing each other. Therefore, the wire harness accommodated in the wire harness protector 1 does not directly touch the outside, and the wire harness can be sufficiently protected from stepping stones and the like.
　第２保護部材３は、車両フロアパネルの床下に配索されるワイヤハーネスの配索形態および当該床下に沿った形状に形成されている。第２保護部材３は、図３に示すように、上面を開口した断面Ｕ字形状の第２周壁部１６が延在されて形成されている。 The second protective member 3 is formed in a wiring form of a wire harness routed under the floor of the vehicle floor panel and a shape along the floor. As shown in FIG. 3, the second protective member 3 is formed by extending a second peripheral wall portion 16 having a U-shaped cross section having an upper surface opened.
　また、第２保護部材３は、第１保護部材２と同様に、電気絶縁性と剛性とを有する剛性部材によって一体成形されている。第２保護部材３は、例えば、ＵＬ９４規格のＶ－０等級の難燃性を有している。 Further, the second protective member 3 is integrally formed of a rigid member having electrical insulation and rigidity, like the first protective member 2. The second protective member 3 has, for example, UL94 standard V-0 flame retardancy.
　また、第２保護部材３には、ボルト等の締結手段によって車両のフロアパネルの床下に第２保護部材３を固定するための取付部４０が設けられている。 Further, the second protective member 3 is provided with an attachment portion 40 for fixing the second protective member 3 under the floor of the vehicle floor panel by fastening means such as bolts.
　第２保護部材３の一端部１８には、図２および図３に示すように、第３保護部材４の他端部２８と係合する第２係合部２２と、第３保護部材４の他端部２８が収容される第２収容部２０と、後述する第２カバー（図４（Ａ）参照）３５と係合する係合突起１９と、が設けられている。 As shown in FIGS. 2 and 3, the one end portion 18 of the second protection member 3 includes a second engagement portion 22 that engages with the other end portion 28 of the third protection member 4, and the third protection member 4. A second accommodation portion 20 in which the other end portion 28 is accommodated, and an engagement protrusion 19 that engages with a second cover (see FIG. 4A) 35 described later are provided.
　第２係合部２２は、図３に示すように、第３保護部材４の大径部（図２参照）３１を受け入れ可能に形成された第２周壁部１６の内周面に設けられている。第２係合部２２は、複数個（図示例では、３個）設けられている。第２係合部２２は、第２周壁部１６の内周面から突出されるとともに該内周面周方向に延在された突条とされている。 As shown in FIG. 3, the second engaging portion 22 is provided on the inner peripheral surface of the second peripheral wall portion 16 formed so as to be able to receive the large-diameter portion (see FIG. 2) 31 of the third protective member 4. Yes. A plurality (three in the illustrated example) of the second engaging portions 22 are provided. The second engaging portion 22 is a protrusion that protrudes from the inner peripheral surface of the second peripheral wall portion 16 and extends in the circumferential direction of the inner peripheral surface.
　また、第２係合部２２の設けられた第２周壁部１６は、断面凹状に形成されている。なお、第２係合部２２の設けられた第２周壁部１６は、第１係合部２２の設けられた第１周壁部６と同様に断面半円形状としてもよい。 Further, the second peripheral wall portion 16 provided with the second engagement portion 22 is formed in a concave cross section. Note that the second peripheral wall portion 16 provided with the second engagement portion 22 may have a semicircular cross-section similarly to the first peripheral wall portion 6 provided with the first engagement portion 22.
　また、第２係合部２２は、第３保護部材４の隣接する大径部３１同士の間に係合される幅に設定されているとともに、第３保護部材４の小径部（図２参照）３２と係合する突出量に設定されている。 The second engaging portion 22 is set to have a width that is engaged between the adjacent large diameter portions 31 of the third protective member 4 and the small diameter portion of the third protective member 4 (see FIG. 2). ) Is set to a protrusion amount that engages with 32.
　このため、第２係合部２２と第３保護部材４とが確実に係合され、第２係合部２２と第３保護部材４との位置ズレが確実に規制されるので、第２保護部材３と第３保護部材４との長手方向の位置ズレ（移動）を規制した状態で、前記第２保護部材３と第３保護部材４とを連結して固定することができる。 For this reason, since the 2nd engagement part 22 and the 3rd protection member 4 are engaged reliably, and the position shift of the 2nd engagement part 22 and the 3rd protection member 4 is controlled reliably, 2nd protection The second protective member 3 and the third protective member 4 can be connected and fixed in a state where the positional deviation (movement) in the longitudinal direction between the member 3 and the third protective member 4 is restricted.
　第２収容部２０は、図２および図３に示すように、上面が開口された断面Ｕ字形状の半円形状に形成されている。第２収容部２０は、その内径が、第３保護部材４の大径部３１の外周面に沿って形成されている。また、第２収容部２０は、その外径が、第１保護部材２の第１収容部１０の内周面よりも小径に形成されている。 As shown in FIG. 2 and FIG. 3, the second housing portion 20 is formed in a semicircular shape having a U-shaped cross section with an upper surface opened. The inner diameter of the second accommodating portion 20 is formed along the outer peripheral surface of the large diameter portion 31 of the third protective member 4. Further, the second housing portion 20 has an outer diameter smaller than the inner peripheral surface of the first housing portion 10 of the first protective member 2.
　すなわち、第２収容部２０は、第３保護部材４の他端部２８が収容可能に形成されているとともに、第１保護部材２の第１収容部１０に収容可能に形成され、第１収容部１０の内周面に第２収容部２０の外周面が重ね合わされるように形成されている。 That is, the second housing portion 20 is formed so that the other end portion 28 of the third protection member 4 can be housed, and can be housed in the first housing portion 10 of the first protection member 2. The outer peripheral surface of the second accommodating portion 20 is formed so as to overlap the inner peripheral surface of the portion 10.
　また、第２収容部２０は、上面が開口された断面Ｕ字形状であることから、開口された上面から可撓性の第３保護部材４の屈曲箇所を外部に露出させて逃がすことができるようになる。 Moreover, since the 2nd accommodating part 20 is U-shaped cross-section by which the upper surface was opened, the bending location of the flexible 3rd protection member 4 can be exposed outside from the opened upper surface, and it can escape. It becomes like this.
　そして、図４（Ｂ）に示すように、第１収容部１０の開口された上面および第２収容部２０の開口された上面の双方から第３保護部材４の屈曲箇所を外部に逃がすことができるようになるので、前記第３保護部材４を大きく屈曲変形させる（すなわち小さい屈曲半径で屈曲させる）ことができるようになる。 And as shown in FIG.4 (B), the bending location of the 3rd protection member 4 can be escaped from both the opened upper surface of the 1st accommodating part 10, and the opened upper surface of the 2nd accommodating part 20. As a result, the third protective member 4 can be greatly bent and deformed (that is, bent with a small bending radius).
　このため、第３保護部材４を大きく屈曲変形させることによって、ワイヤハーネスプロテクタを運搬時などにおけるコンパクト形態に容易に変形させることができるようになる。 For this reason, by greatly bending and deforming the third protective member 4, the wire harness protector can be easily deformed into a compact form during transportation.
　なお、第１収容部１０および第２収容部の双方は、開口された上面が車両のフロアパネルの床下（すなわち車両の外面）に面して搭載されるので、ワイヤハーネスプロテクタ１の車両搭載時には、上面の開口がフロアパネルの床下によって塞がれる。 In addition, since both the 1st accommodating part 10 and the 2nd accommodating part are mounted so that the opened upper surface may face the floor under the floor panel of a vehicle (namely, outer surface of a vehicle), when the wire harness protector 1 is mounted in a vehicle The opening on the top surface is blocked by the floor panel under the floor.
　このため、第１収容部１０および第２収容部の双方に第３保護部材４が収容され、該第３保護部材４が外部に露出しないように保護されるので、第３保護部材４に収容されるワイヤハーネスに対して優れた保護性能を発揮することができる。 For this reason, the third protective member 4 is accommodated in both the first accommodating portion 10 and the second accommodating portion, and the third protective member 4 is protected so as not to be exposed to the outside. The protective performance which was excellent with respect to the wire harness made can be exhibited.
　係合突起１９は、図３に示すように、第２係合部２２の形成された箇所の第２周壁部１６の外周面に設けられている。係合突起１９は、前記外周面から突出され、第２カバー（図４（Ａ）参照）３５と係合可能に形成されている。 As shown in FIG. 3, the engagement protrusion 19 is provided on the outer peripheral surface of the second peripheral wall portion 16 where the second engagement portion 22 is formed. The engaging protrusion 19 protrudes from the outer peripheral surface and is formed so as to be engageable with a second cover 35 (see FIG. 4A).
　第２カバー３５は、図４（Ａ）および図４（Ｂ）に示すように、配索形態に沿って延在された第２周壁部１６の上面の開口を塞ぐように形成されている。また、第２カバー３５は、第２周壁部１６に設けられた図示しない複数個の係合突起によって、前記第２周壁部１６に係合されるように形成されている。 The 2nd cover 35 is formed so that the opening of the upper surface of the 2nd surrounding wall part 16 extended along the routing form may be plugged, as shown to FIG. 4 (A) and FIG. 4 (B). The second cover 35 is formed to be engaged with the second peripheral wall portion 16 by a plurality of engagement protrusions (not shown) provided on the second peripheral wall portion 16.
　また、第２カバー３５は、第２保護部材３の一端部１８と、該一端部１８の係合部（図３参照）２２に係合された第３保護部材４の他端部（図２参照）２８と、を覆うように形成されている。また、第２カバー３５の内周面には、前記第３保護部材４の他端部２８と係合する図示しない係合部が設けられている。 The second cover 35 has one end 18 of the second protective member 3 and the other end (see FIG. 2) of the third protective member 4 engaged with the engaging portion (see FIG. 3) 22 of the one end 18. Reference) 28 is formed so as to cover. An engagement portion (not shown) that engages with the other end portion 28 of the third protection member 4 is provided on the inner peripheral surface of the second cover 35.
　なお、第２カバー３５を第２保護部材３に取り付けない場合であっても、第２周壁部１６の開口された上面と車両のフロアパネルの床下とを対向させてワイヤハーネスプロテクタ１が搭載されるので、該ワイヤハーネスプロテクタ１に収容されたワイヤハーネスが直接外部に触れることはなく、飛び石等からワイヤハーネスを十分に保護することができる。 Even when the second cover 35 is not attached to the second protective member 3, the wire harness protector 1 is mounted with the upper surface of the second peripheral wall portion 16 and the under floor of the vehicle floor panel facing each other. Therefore, the wire harness accommodated in the wire harness protector 1 does not directly touch the outside, and the wire harness can be sufficiently protected from stepping stones and the like.
　第３保護部材４は、図２に示すように、断面円形状の第３周壁部２６が延在されて形成されている。第３保護部材４は、一端部２７および他端部２８の双方が開口されている。すなわち、第３保護部材４は、ワイヤハーネスを収容可能な円筒形状に形成されている。また、第３保護部材４は、いわゆるコルゲートチューブである。 As shown in FIG. 2, the third protective member 4 is formed by extending a third peripheral wall portion 26 having a circular cross section. The third protective member 4 has both one end portion 27 and the other end portion 28 opened. That is, the 3rd protection member 4 is formed in the cylindrical shape which can accommodate a wire harness. The third protective member 4 is a so-called corrugated tube.
　第３保護部材４は、例えば、フッ素系難燃剤や塩素系難燃剤や臭素系難燃剤を使用しないノンハロゲン樹脂組成物であるナイロン樹脂などの電気絶縁性と可撓性とを有する可撓性部材によって一体成形されている。第３保護部材４は、例えば、ＵＬ９４規格のＶ－０等級の難燃性を有している。 The third protective member 4 is, for example, a flexible member having electrical insulation and flexibility, such as a nylon resin that is a non-halogen resin composition that does not use a fluorine-based flame retardant, a chlorine-based flame retardant, or a bromine-based flame retardant. Are integrally molded. The third protective member 4 has, for example, UL94 standard V-0 flame retardancy.
　このように、第３保護部材４は、可撓性部材によって形成されているので、前記第３周壁部２６の延在方向に対して屈伸可能となっている。 Thus, since the third protective member 4 is formed of a flexible member, it can bend and stretch with respect to the extending direction of the third peripheral wall portion 26.
　このため、梱包時には第３保護部材４を屈曲させることによって、ワイヤハーネスプロテクタ１をコンパクト形態とすることができ、また、車両のフロアパネルの床下への搭載時には第３保護部材４を伸展させることによって、ワイヤハーネスプロテクタ１を配索形態とすることができる。 For this reason, by bending the 3rd protection member 4 at the time of packing, the wire harness protector 1 can be made into a compact form, and the 3rd protection member 4 is extended at the time of mounting under the floor of a vehicle floor panel. By this, the wire harness protector 1 can be set in the routing form.
　第３周壁部２６は、該第３周壁部２６の延在方向に対して交互に連続する環状の大径部３１と小径部３２とを備えている。 The third peripheral wall portion 26 includes annular large-diameter portions 31 and small-diameter portions 32 that are alternately continuous with respect to the extending direction of the third peripheral wall portion 26.
　このように、第３保護部材４が、可撓性を有するコルゲートチューブで構成されているので、簡単な構成でワイヤハーネスプロテクタ１の一部を屈伸可能にすることができる。また、汎用性のコルゲートチューブは安価に入手可能であるので、ワイヤハーネスプロテクタ１のコストアップを抑制できる。 Thus, since the third protective member 4 is formed of a corrugated tube having flexibility, a part of the wire harness protector 1 can be bent and stretched with a simple configuration. Moreover, since the versatile corrugated tube can be obtained at a low cost, the cost increase of the wire harness protector 1 can be suppressed.
　以上に説明したように、本発明の一実施形態にかかるワイヤハーネスプロテクタ１は、ワイヤハーネスが収容される第１保護部材２と、前記ワイヤハーネスが収容される第２保護部材３と、前記ワイヤハーネスが収容され且つ両端部が開口された円筒形状の可撓性を有する第３保護部材４と、を備え、前記第３保護部材４の一端部２７と前記第１保護部材２の一端部８とが連結されて連通されるとともに当該第３保護部材４の他端部２８と前記第２保護部材３の一端部１８とが連結されて連通され、前記第１保護部材２および前記第２保護部材３の双方が、剛性部材で形成され、前記第１保護部材２の前記一端部８には、前記第３保護部材４の一端部２７が収容される第１収容部１０が設けられ、前記第２保護部材３の前記一端部１８には、前記第３保護部材４の他端部２８が収容される第２収容部２０が設けられ、前記第１収容部１０は、上面が開口された断面Ｕ字形状であるとともに前記第２収容部２０の先端部分が収容されることを特徴とするものである。 As described above, the wire harness protector 1 according to the embodiment of the present invention includes the first protective member 2 in which the wire harness is accommodated, the second protective member 3 in which the wire harness is accommodated, and the wire.
