Description

本発明は、電線保護管の組立治具に関する。   The present invention relates to an assembly jig for a wire protection tube.

従来、自動車の床下に配線される高圧ケーブルは、外部からの衝撃等から電線を保護する目的で、(特許文献1)に示されるような強固なプロテクタで覆われている。   2. Description of the Related Art Conventionally, a high-voltage cable wired under the floor of an automobile is covered with a strong protector as shown in (Patent Document 1) for the purpose of protecting the electric wire from an external impact or the like.

特開2002−186131号公報JP 2002-186131 A

ところで、上記したプロテクタは、外部の衝撃等から電線を保護することができるものの可撓性を有していないため、配置する場所に応じて湾曲させることができず、使用する場所が限られてしまうという問題があった。   By the way, although the above protector can protect the electric wire from an external impact or the like but does not have flexibility, it cannot be bent according to the place where it is placed, and the place where it is used is limited. There was a problem that.

そこで、本願の発明者は、可撓性を有する電線保護管として、複数の単位チューブを連結して構成され、その内部に電線が挿通されるものであって、各単位チューブは、電線が挿通される電線挿通孔を有した筒部と、筒部に連なり、曲面状の外周面を有する曲面部と、曲面部とは反対側にて前記筒部に連なり、隣接する単位チューブの前記曲面部と嵌り合ってその曲面部の前記外周面に対して摺動する凹状面部と、を備える構成を発明するに至った。   Therefore, the inventor of the present application is configured by connecting a plurality of unit tubes as a flexible electric wire protection tube, in which electric wires are inserted, and each unit tube has an electric wire inserted therethrough. A cylindrical portion having a wire insertion hole, a curved surface portion connected to the cylindrical portion, a curved outer peripheral surface, and the curved surface portion of the adjacent unit tube connected to the cylindrical portion on the opposite side of the curved surface portion And a concave surface portion that slides with respect to the outer peripheral surface of the curved surface portion.

ここで、電線保護管を組み立てるに当たって、1個ずつ順番に単位チューブを組付けていくのでは作業効率の観点から望ましくない。   Here, in assembling the wire protection tube, it is not desirable from the viewpoint of work efficiency to assemble the unit tubes one by one in order.

本発明は上記のような事情に基づいて完成されたものであって、可撓性を有し、かつ、強度の強い電線保護管の組立治具を提供することを目的とする。   The present invention has been completed based on the above circumstances, and an object thereof is to provide an assembly jig for an electric wire protection tube having flexibility and high strength.

本発明は、複数の単位チューブを連結して構成され、その内部に電線が挿通される電線保護管の組立治具であって、前記各単位チューブは、前記電線が挿通される電線挿通孔を有した筒部と、前記筒部の一端側に連なり、曲面状の外周面を有する曲面部と、前記筒部の他端側に連なり、隣接する単位チューブの前記曲面部と嵌り合ってその曲面部の前記外周面に対して摺動する凹状面部と、を備えるとともに、前記各単位チューブは、前記筒部の軸方向に沿った面で分割された複数の分割単位チューブからなり、前記電線保護管の組立治具は、前記複数の分割単位チューブを前記電線挿通孔が連なる方向に並べて保持する一対の保持部材を有し前記各保持部材には、前記各分割単位チューブごとに、前記分割単位チューブを係止する単位チューブ係止部が設けられているところに特徴を有する(手段1)。   The present invention is an assembly jig for an electric wire protection tube configured by connecting a plurality of unit tubes, and an electric wire is inserted into the unit tube, and each unit tube has an electric wire insertion hole through which the electric wire is inserted. A cylindrical portion having a curved surface portion that has a curved outer peripheral surface, and a curved surface portion that is continuous with the other end side of the cylindrical portion, and fits with the curved surface portion of an adjacent unit tube. A concave surface portion that slides with respect to the outer peripheral surface of the portion, and each unit tube includes a plurality of divided unit tubes divided by a surface along the axial direction of the cylindrical portion, and the electric wire protection The tube assembly jig has a pair of holding members that hold the plurality of division unit tubes side by side in a direction in which the electric wire insertion holes are continuous, and each of the division unit tubes includes the division unit. Unit tube for locking the tube It has a feature where the blanking engagement portion is provided (unit 1).

かかる組立治具を用いた電線保護管の組み付けについて説明すると、一対の保持部材のそれぞれに、各分割単位チューブを単位チューブ係止部に係止することで分割単位チューブを電線挿通孔が連なる方向に連ねる。全ての分割単位チューブが係止されて分割単位チューブが電線挿通孔が連なる方向に連ねて収容されると、各分割単位チューブについては、それぞれが単位チューブ係止部に係止された状態であるから、各分割単位チューブが容易にばらばらにならない。
そして、例えば、一方の保持部材の分割単位チューブの電線挿通孔の部分に電線を配し、他方の保持部材を、対になる分割単位チューブ同士が嵌合するように一方の保持部材に突き合わせる。
The assembly of the electric wire protection tube using such an assembly jig will be described. The direction in which the electric wire insertion holes are connected to the divided unit tubes by engaging the divided unit tubes with the unit tube engaging portions on each of the pair of holding members. It continues to. When all the divided unit tubes are locked and the divided unit tubes are accommodated in the direction in which the wire insertion holes are connected, each divided unit tube is in a state of being locked to the unit tube locking portion. Therefore, each divided unit tube does not easily separate.
Then, for example, an electric wire is arranged in the portion of the electric wire insertion hole of the divided unit tube of one holding member, and the other holding member is abutted against one holding member so that the divided divided unit tubes are fitted to each other. .

このようにすれば、複数の単位チューブが連結された電線保護管を組み立てることができる。なお、上記組立において分割単位チューブに電線を配さず、電線が挿通されない電線保護管を組立てる際(電線保護管の組立後に電線を挿通させる場合)の組立についても、上記組立治具を用いることで容易になる。   If it does in this way, the electric wire protection tube with which the several unit tube was connected can be assembled. In the above assembly, the assembly jig is also used for the assembly when the electric wire protection tube that does not insert the electric wire into the divided unit tube and the electric wire is not inserted (when the electric wire is inserted after the electric wire protection tube is assembled) is assembled. It becomes easy.

そして、このような電線保護管に電線が挿通されると、電線を外部からの強い衝撃等から保護できる。また、複数の単位チューブは、単位チューブの曲面部とこれと隣接する単位チューブの凹状面部とが嵌り合ってその曲面部の外周面に対して摺動するから、これらの単位チューブが連結されて構成された電線保護管は、使用する場所に応じた形状に曲げることができる。即ち、可撓性を有し、かつ、強度の強い電線保護管とすることができる。   And if an electric wire is inserted in such an electric wire protection tube, an electric wire can be protected from the strong impact from the outside, etc. In addition, since the plurality of unit tubes slide with respect to the outer peripheral surface of the curved surface portion of the unit tube, the curved surface portion of the unit tube and the concave surface portion of the adjacent unit tube are fitted to each other. The constructed wire protection tube can be bent into a shape corresponding to the place of use. That is, the electric wire protective tube having flexibility and high strength can be obtained.

手段1の構成に加えて、前記分割単位チューブの凹状面部の外周面には、係止凹部が設けられており、前記単位チューブ係止部は、前記係止凹部に嵌め込まれて係止される係止凸部であるようにしてもよい(手段2)。
手段2の構成によれば、簡易な構成で分割単位チューブを保持部材に係止させることができる。また、凹状面部の外周面に設けられる係止凹部は、保持部材の側を凹部とする場合よりも比較的弾性変形しやすいから容易に係止凸部を係止凹部に係止させることができる。
In addition to the structure of the means 1, a locking recess is provided on the outer peripheral surface of the concave surface portion of the divided unit tube, and the unit tube locking portion is fitted into the locking recess and locked. You may make it be a latching convex part (means 2).
According to the configuration of the means 2, the division unit tube can be locked to the holding member with a simple configuration. Moreover, since the latching recessed part provided in the outer peripheral surface of a concave surface part is comparatively easy to deform elastically compared with the case where the side of a holding member is used as a recessed part, a latching convex part can be easily latched by a latching recessed part. .

手段1又は手段2の構成に加えて、前記一対の保持部材は、前記分割単位チューブの電線挿通孔が連なる方向に長い形状の底部とこの底部の両側縁から立ち上がる側壁部とを有し、一方の保持部材の側壁部の上端部が他方の保持部材の側壁部の上端部に突き当てられることにより、前記各保持部材に収容された前記分割単位チューブ同士が嵌り合って電線保護管が形成されるようにしてもよい(手段3)。
手段3の構成によれば、保持部材同士を突き当てれば電線保護管が組み立てられるから、電線保護管の組立が容易になる。
In addition to the configuration of the means 1 or 2, the pair of holding members have a bottom portion that is long in the direction in which the electric wire insertion holes of the divided unit tube are continuous and side wall portions that rise from both side edges of the bottom portion, When the upper end portion of the side wall portion of the holding member is abutted against the upper end portion of the side wall portion of the other holding member, the divided unit tubes accommodated in the holding members are fitted to each other to form a wire protection tube. (Means 3).
According to the configuration of the means 3, since the electric wire protection tube is assembled when the holding members are brought into contact with each other, the electric wire protection tube can be easily assembled.

手段1ないし手段3のいずれか一項に記載の構成に加えて、前記一方の保持部材における側壁部の上端部には、上方に突出する嵌合ピンが形成されており、前記他方の保持部材の側壁部の上端部には、前記嵌合ピンが挿入されるピン挿入凹部が形成されているようにしてもよい(手段4)。
手段4の構成によれば、保持部材同士を突き当てる際の位置合わせが容易になる。
In addition to the structure according to any one of the means 1 to 3, a fitting pin protruding upward is formed at the upper end of the side wall of the one holding member, and the other holding member A pin insertion recess into which the fitting pin is inserted may be formed at the upper end of the side wall (means 4).
According to the structure of the means 4, the positioning at the time of abutting holding members becomes easy.

手段1ないし手段4のいずれか一項に記載の構成に加えて、前記単位チューブは、一対の前記分割単位チューブのうちの一方に形成されたロックピンが他方に形成されたロック孔に挿入されて係止されるものであって、前記嵌合ピンは、前記ロックピンが前記ロック孔に挿入されるのに先立って、前記ピン挿入凹部に挿入されるようにしてもよい(手段5)。
手段5の構成によれば、ロックピンよりも嵌合ピンが先に挿入されて位置合わせが行われるから、ロックピンの損傷を防止することができる。
In addition to the structure according to any one of the means 1 to 4, the unit tube has a lock pin formed on one of the pair of divided unit tubes inserted into a lock hole formed on the other. The fitting pin may be inserted into the pin insertion recess before the lock pin is inserted into the lock hole (means 5).
According to the structure of the means 5, since the fitting pin is inserted earlier than the lock pin and the alignment is performed, damage to the lock pin can be prevented.

手段1ないし手段5のいずれか一項に記載の構成に加えて、前記分割単位チューブの凹状面部には、係止孔が設けられており、前記単位チューブ係止部は、前記係止孔の孔縁に係止するものであり、全ての前記単位チューブ係止部がそれぞれ対応する前記係止孔の孔縁に係止する係止位置から、全ての単位チューブ係止部の前記係止孔への係止が解除される解除位置に変更可能な解除機構を有するようにしてもよい(手段6)。
手段6の構成によれば、電線保護管の組立後の係止状態の解除が容易になる。
In addition to the structure according to any one of the means 1 to 5, the concave surface portion of the divided unit tube is provided with a locking hole, and the unit tube locking portion is formed of the locking hole. The locking holes of all the unit tube locking portions are locked from the locking positions at which the unit tube locking portions are locked to the hole edges of the corresponding locking holes. There may be a changeable release mechanism at the release position at which the lock is released (means 6).
According to the configuration of the means 6, it is easy to release the locked state after the assembly of the wire protection tube.

手段1ないし手段6のいずれか一項に記載の構成に加えて、前記電線保護管は、複数の前記単位チューブを連結して構成される連結単位チューブと、筒状プロテクタ部と、連結単位チューブと筒状プロテクタ部とを連結する連結部材と、からなり、前記保持部材のうち、前記電線保護管の電線挿通孔が連なる方向の端部には、前記連結部材に係止して前記連結部材を位置決めする位置決め部が設けられているようにしてもよい(手段7)。   In addition to the configuration according to any one of the means 1 to 6, the wire protection tube includes a connection unit tube configured by connecting a plurality of the unit tubes, a cylindrical protector portion, and a connection unit tube. And a connecting member that connects the tubular protector portion, and of the holding member, an end portion in a direction in which the wire insertion holes of the wire protection tube are connected to each other is engaged with the connecting member and the connecting member. There may be provided a positioning portion for positioning (means 7).

可撓制を有しつつ電線を保護するという点では、電線保護管の全ての部分を連結単位チューブで構成することも可能であるが、連結単位チューブの部分については、可撓性を有するための構成により、筒状プロテクタ部よりも体積が大きくなりやすく、その分重量が重くなりやすい。そこで、可撓性を有する必要のある部分については、連結単位チューブとし、可撓性を有する必要のない部分については、筒状プロテクタ部により電線を保護することととすれば、全てを連結単位チューブとする場合よりも電線保護管を軽量化することができる。
このように連結単位チューブと筒状プロテクタ部とを有する場合に、これらの間を連結部材で連結すれば、連結単位チューブと筒状プロテクタ部との間の隙間による電線の露出を防止することができるため望ましい。
手段7の構成では、かかる場合に用いる連結部材を利用して、電線保護管の組立の際の位置決めをすることができる。
In terms of protecting the electric wire while having flexibility, it is possible to configure all parts of the electric wire protection tube with a connecting unit tube, but the connecting unit tube part is flexible. With this configuration, the volume is likely to be larger than that of the cylindrical protector portion, and the weight is likely to increase accordingly. Therefore, if the portion that needs to be flexible is a connecting unit tube, and the portion that does not need to be flexible is to protect the electric wire with a cylindrical protector part, all the connecting unit tube. The electric wire protection tube can be reduced in weight compared with the case where the tube is used.
Thus, when it has a connection unit tube and a cylindrical protector part, if these are connected with a connection member, exposure of the electric wire by the crevice between a connection unit tube and a cylindrical protector part may be prevented. This is desirable because it can be done.
In the configuration of the means 7, the connecting member used in such a case can be used for positioning when assembling the wire protection tube.

本発明によれば、可撓性を有し、かつ、強度の強い電線保護管を組立てるための組立治具を提供することができる。   According to the present invention, it is possible to provide an assembly jig for assembling a flexible and strong electric wire protection tube.

As shown in FIG. 15, the assembly jig 80 of the wire protection tube 10 includes a pair of holding members 81 and 81 that hold a plurality of divided unit tubes 31A side by side in a direction in which the wire insertion holes 21 (29, 51) are continuous. (Only one holding member 81 is shown in FIG. 15).

各保持部材81,81は、共に同形で、例えば金属製であり、長尺の板状をなす底板部82(本発明の「底部」の一例)と、底板部82の両側縁部から立ち上がる一対の側壁部83,83と、を有する。   Each holding member 81, 81 is the same shape and is made of, for example, metal, and is a pair of rising from a bottom plate portion 82 (an example of a “bottom portion” of the present invention) having a long plate shape and both side edges of the bottom plate portion 82. Side wall portions 83, 83.

底板部82には、上方に突出する係止凸部84(本発明の「単位チューブ係止部」の一例)が、長手方向に等間隔で設けられている。この係止凸部84は、分割単位チューブ31A,31Aの凹状面部37に形成された係止孔37A(本発明の「係止凹部」の一例)の径よりわずかに大きい(太い)。言い換えると、係止凸部84の径は、係止凸部84が係止孔37Aに嵌め込まれる(陥入される)と、保持部材81,81を逆さにした程度では抜け落ちないように係止状態が維持される程度の大きさ(太さ)とされる。   The bottom plate portion 82 is provided with locking projections 84 (an example of the “unit tube locking portion” of the present invention) protruding upward at equal intervals in the longitudinal direction. The locking projection 84 is slightly larger (thick) than the diameter of a locking hole 37A (an example of the “locking recess” in the present invention) formed in the concave surface portion 37 of the divided unit tubes 31A and 31A. In other words, the diameter of the locking projection 84 is set so that when the locking projection 84 is fitted (indented) into the locking hole 37 </ b> A, the holding members 81, 81 are inverted so that they do not fall off. The size (thickness) is such that the state is maintained.

隣接する係止凸部84の間隔は、複数の分割単位チューブ31A,31Aを電線挿通孔29(及び撓み許容孔36)が連なるように並べた際の、隣接する係止孔37Aの間隔となる。   The interval between the adjacent locking projections 84 is the interval between the adjacent locking holes 37A when the plurality of divided unit tubes 31A and 31A are arranged so that the electric wire insertion holes 29 (and the bending allowance holes 36) are continuous. .

側壁部83,83は、底板部82の全長に亘って設けられており、その高さは、係止凸部84を分割単位チューブ31Aの係止孔37Aに係止させた際(分割単位チューブ31Aを保持部材81,81に保持させた際)の分割端面の高さにほぼ等しくなっている(図20参照)。   The side wall parts 83, 83 are provided over the entire length of the bottom plate part 82, and the height thereof is determined when the locking projection 84 is locked in the locking hole 37A of the divided unit tube 31A (the divided unit tube). The height is substantially equal to the height of the divided end face (when 31A is held by the holding members 81, 81) (see FIG. 20).

側壁部83,83には、図15,図16に示すように、その長手方向の一方の端部の上面(上端部)に、上方に突出する嵌合ピン85Aが設けられ、他方の端部に嵌合ピン85Aが挿入可能な径(大きさ)及び深さのピン挿入凹部85Bが設けられている。   As shown in FIGS. 15 and 16, the side walls 83, 83 are provided with fitting pins 85 </ b> A protruding upward on the upper surface (upper end) of one end in the longitudinal direction, and the other end A pin insertion recess 85B having a diameter (size) and a depth into which the fitting pin 85A can be inserted is provided.

この嵌合ピン85A及びピン挿入凹部85Bの組み合わせは、一対の側壁部83,83のうち、一方の側壁部83と他方の側壁部83とで、位置が逆になっている(保持部材81,81を180度回転させると同じ位置になる配置である)。   The combination of the fitting pin 85A and the pin insertion recess 85B is reverse in position between the one side wall 83 and the other side wall 83 of the pair of side walls 83, 83 (holding member 81, 83). It is the same position when 81 is rotated 180 degrees).

ここで、嵌合ピン85Aの長さ(高さ)は、電線保護管10の組立時に一対の保持部材81,81が向き合う方向に近づけていく際に、各単位チューブ31のロック部38がロック孔39Aに挿入されるのに先立って、嵌合ピン85Aがピン挿入凹部85Bに挿入される嵌合ピン85Aの長さが設定されている。具体的には、図23に示すように、嵌合ピン85Aの基端部は、ロック部38の基端部よりも上方に配されており、嵌合ピン85Aの先端部の高さは、ロック部38の先端部の高さよりも高い位置に形成されている。一方、ピン挿入凹部85Bの挿入位置の高さは、ロック受け部39の挿入位置の高さと同じである。なお、本実施形態では、嵌合ピン85Aとロック部38とは同じ方向に突出することとしたが、嵌合ピン85Aとロック部38とが逆方向に突出するものでもよく、この場合でも、ロック部38がロック孔39Aに挿入されるより先に嵌合ピン85Aがピン挿入凹部85Bに挿入されるようにすればよい。   Here, the length (height) of the fitting pin 85 </ b> A is such that the lock portion 38 of each unit tube 31 is locked when the pair of holding members 81, 81 are brought closer to each other when the electric wire protection tube 10 is assembled. Prior to being inserted into the hole 39A, the length of the fitting pin 85A into which the fitting pin 85A is inserted into the pin insertion recess 85B is set. Specifically, as shown in FIG. 23, the proximal end portion of the fitting pin 85A is disposed above the proximal end portion of the lock portion 38, and the height of the distal end portion of the fitting pin 85A is The lock portion 38 is formed at a position higher than the height of the tip portion. On the other hand, the height of the insertion position of the pin insertion recess 85 </ b> B is the same as the height of the insertion position of the lock receiving portion 39. In this embodiment, the fitting pin 85A and the lock portion 38 protrude in the same direction, but the fitting pin 85A and the lock portion 38 may protrude in the opposite direction. The fitting pin 85A may be inserted into the pin insertion recess 85B before the lock portion 38 is inserted into the lock hole 39A.

また、側壁部83,83の長手方向の端部における内面側には、図15に示すように、連結位置決め凹部86が形成されている。この連結位置決め凹部86は、連結部材41,48に設けられた連結位置決め凸部46,56と嵌合することにより、連結部材41,48の(電線挿通孔が連なる方向への)位置決めがされるようになっている。   Further, as shown in FIG. 15, a connection positioning recess 86 is formed on the inner surface side of the end portions in the longitudinal direction of the side walls 83, 83. The connection positioning recess 86 is engaged with the connection positioning protrusions 46 and 56 provided in the connection members 41 and 48, thereby positioning the connection members 41 and 48 (in the direction in which the wire insertion holes are continuous). It is like that.

なお、側壁部83,83には、配置する分割単位チューブ31Aのロック部38及びロック受け部39の位置に対応して、ロック収容凹部87が凹設されている。ロック収容凹部87は、ロック部38及びロック受け部39が凹状面部37よりも幅方向に若干突き出ているため、これらを(保持部材81の幅を比較的狭くしても)側壁部83に当たらずに、収容することができる。また、このロック収容凹部87にロック部38及びロック受け部39を嵌め込めば分割単位チューブ31Aを係止凸部84に係止させることもできるため、分割単位チューブ31Aの係止を容易にすることができる。   The side walls 83, 83 are provided with lock receiving recesses 87 corresponding to the positions of the lock part 38 and the lock receiving part 39 of the divided unit tube 31 </ b> A to be arranged. Since the lock portion 38 and the lock receiving portion 39 protrude slightly in the width direction from the concave surface portion 37, the lock accommodating recess 87 is not exposed to the side wall portion 83 (even if the width of the holding member 81 is relatively narrow). Without being accommodated. Further, if the lock portion 38 and the lock receiving portion 39 are fitted in the lock receiving recess 87, the division unit tube 31A can be engaged with the engagement projection 84, so that the division unit tube 31A can be easily engaged. be able to.

次に、組立治具80を用いた電線保護管10の組み立て方法について説明する。
まず一方の保持部材81について、図17に示すように、凹状面部付連結部材41を構成する分割連結部材41Aを連結位置決め凹部86に連結位置決め凸部46を嵌合させつつ、係止孔37Aに係止凸部84を挿入して係止させる。
Next, a method for assembling the wire protection tube 10 using the assembly jig 80 will be described.
First, with respect to one holding member 81, as shown in FIG. 17, the split connecting member 41 </ b> A constituting the connecting member 41 with the concave surface portion is fitted into the connecting positioning concave portion 86 and the connecting positioning convex portion 46 is fitted into the locking hole 37 </ b> A. The locking projection 84 is inserted and locked.

次に、図18に示すように、分割連結部材41Aの凹状面部42に、分割単位チューブ31Aの曲面部35が嵌るように、分割単位チューブ31Aの係止孔37Aに係止凸部84を挿入して係止させ、電線挿通孔が連なる方向に隣接する分割単位チューブ31Aを順番に、分割単位チューブ31Aの係止孔37Aに係止凸部84を挿入して係止させていく。   Next, as shown in FIG. 18, the locking convex portion 84 is inserted into the locking hole 37 </ b> A of the divided unit tube 31 </ b> A so that the curved surface portion 35 of the divided unit tube 31 </ b> A fits into the concave surface portion 42 of the divided connecting member 41 </ b> A. Then, the division unit tubes 31A adjacent to each other in the direction in which the wire insertion holes are continuous are sequentially inserted into the engagement holes 37A of the division unit tubes 31A to be engaged.

次に、図19に示すように、曲面部付連結部材48を構成する分割連結部材48Aを連結位置決め凹部86に連結位置決め凸部56を嵌合させつつ、係止孔37Aに係止凸部84を挿入して係止させる。
次に、図21に示すように、分割プロテクタ22を分割連結部材41A及び分割連結部材48Aのそれぞれに取り付ける。
そして、図22に示すように、長手方向に連ねられた電線挿通孔に電線70を配し、分割連結部材41A及び分割連結部材48Aに取り付けた分割プロテクタ22に、対をなす分割プロテクタ22を嵌め合わせて、分割プロテクタ22の被溶着部28を溶着して一体となった筒状プロテクタ部20とする。
Next, as shown in FIG. 19, the split connecting member 48A constituting the connecting member 48 with the curved surface portion is fitted into the connecting positioning concave portion 86 with the connecting positioning convex portion 56, and the locking convex portion 84 is fitted into the locking hole 37A. Insert and lock.
Next, as shown in FIG. 21, the split protector 22 is attached to each of the split connecting member 41A and the split connecting member 48A.
And as shown in FIG. 22, the electric wire 70 is distribute | arranged to the electric wire penetration hole continued in the longitudinal direction, and the division | segmentation protector 22 which makes a pair is fitted to the division | segmentation protector 22 attached to the division | segmentation connection member 41A and the division | segmentation connection member 48A. In addition, the welded portion 28 of the divided protector 22 is welded to form a cylindrical protector portion 20 integrated.

そして、他方の保持部材81,81についても同様に、分割連結部材41A、複数の分割単位チューブ31A及び分割連結部材48Aについて順番に係止孔37Aに係止凸部84を挿入して係止させる(図19)。
次に、分割連結部材41A,48A及び複数の分割単位チューブ31Aを全て係止させたら、作業者は、当該他方の保持部材81(電線70が配されていない側)を持ち上げて裏返す。このときは、電線挿通孔が連なるように連結された分割単位チューブ31A及び連結部材41,48は、それぞれが対応する係止凸部84に係止されているから、抜け落ちない。
Similarly, with respect to the other holding members 81, 81, the locking projections 84 are inserted into the locking holes 37A in order and locked with respect to the divided connecting member 41A, the plurality of divided unit tubes 31A, and the divided connecting member 48A. (FIG. 19).
Next, when all of the divided connecting members 41A and 48A and the plurality of divided unit tubes 31A are locked, the operator lifts the other holding member 81 (the side where the electric wire 70 is not disposed) and turns it over. At this time, the divided unit tubes 31A and the connecting members 41 and 48 connected so that the electric wire insertion holes are continuous are locked to the corresponding locking projections 84, and thus do not fall off.

そして、図23に示すように、他方の保持部材81を一方の保持部材81に向かい合わせ、嵌合ピン85Aがピン挿入凹部85Bに挿入されるように近づける。   Then, as shown in FIG. 23, the other holding member 81 is opposed to the one holding member 81 and brought close to the fitting pin 85A so as to be inserted into the pin insertion recess 85B.

嵌合ピン85Aがピン挿入凹部85Bに挿入されると、その後に、分割単位チューブ31Aのロック部38が相手側の分割単位チューブ31Aのロック孔39Aに挿入される。
ロック部38がロック孔39Aに挿入されてロックされると、図24に示すように、他方の保持部材81の側壁部83,83の上端部の面が、一方の保持部材81の側壁部83,83の上端部の面に突き当たる(保持部材81,81同士が突き当たる)。
When the fitting pin 85A is inserted into the pin insertion recess 85B, thereafter, the lock portion 38 of the division unit tube 31A is inserted into the lock hole 39A of the other division unit tube 31A.
When the lock portion 38 is inserted into the lock hole 39A and locked, the upper end surfaces of the side wall portions 83 and 83 of the other holding member 81 are aligned with the side wall portion 83 of the one holding member 81 as shown in FIG. , 83 abut against the surface of the upper end portion (the holding members 81 abut against each other).

これにより、電線保護管10が組立てられたことが分かるから、作業者は、他方の保持部材81を引き離す。すると、今度は、単位チューブ31や連結部材41,48は、係止凸部84への係止よりも強い力でロック部38及びロック受け部39でロックされているから単位チューブ31が分割単位チューブ31A,31Aや分割連結部材41A,41A(48A,48A)に分離することはなく、片方の保持部材81における係止凸部84の係止孔37Aへの係止状態が解除されて、当該片方の保持部材81が電線保護管10から引き離される。
そして、作業者が電線保護管10を掴んで持ち上げると、全ての係止凸部84の係止孔37Aへの係止が解除されて、電線70が挿通された状態の電線保護管10が組み立てられる。
Thereby, since it turns out that the electric wire protection tube 10 was assembled, the operator pulls the other holding member 81 apart. Then, since the unit tube 31 and the connecting members 41 and 48 are locked by the lock portion 38 and the lock receiving portion 39 with a force stronger than the locking to the locking convex portion 84, the unit tube 31 is divided into units. The tube 31A, 31A and the divided connecting members 41A, 41A (48A, 48A) are not separated, and the locking state of the locking projection 84 in the holding member 81 on one side is released to the locking hole 37A. One holding member 81 is pulled away from the wire protection tube 10.
When the operator grips and lifts the wire protection tube 10, all the locking projections 84 are released from the locking holes 37 </ b> A, and the wire protection tube 10 with the wires 70 inserted is assembled. It is done.

なお、単位チューブ31や連結部材41,48の取り付けに先立って、電線70の外周にグリースや樹脂(例えば、シリコン系の樹脂)を塗布し、隙間(空気層)をなくして放熱性を更に向上させるようにしてもよい。   Prior to attaching the unit tube 31 and the connecting members 41 and 48, grease or resin (for example, silicon-based resin) is applied to the outer periphery of the electric wire 70 to eliminate gaps (air layers) and further improve heat dissipation. You may make it make it.

そして、このようにして組み付けられた電線保護管10は、図14に示すように、連結単位チューブ30の部分により、車内等の配索する場所の形状に応じて曲げることができる。   And the electric wire protection tube 10 assembled | attached in this way can be bent by the part of the connection unit tube 30 according to the shape of the place to route, such as the inside of a vehicle, as shown in FIG.

本実施形態によれば、以下の効果を奏する。
(1)組立治具80を用いることにより、組立の際に複数の単位チューブ31が係止(保持)されてばらばらにならないから、電線保護管10の組み立てが容易になる。なお、上記組立において分割単位チューブ31に電線70を配さず、電線70が挿通されない電線保護管10を組立てる際(電線保護管10の組立後に電線保護管10の一方から電線70を挿通させる場合)も、上記と同様に組立治具80を用いることで組立が容易になる。
そして、このような電線保護管10に電線70が挿通されると、外部からの強い衝撃等から電線70を保護できる。また、複数の単位チューブ31は、単位チューブ31の曲面部35とこれと隣接する単位チューブ31の凹状面部37とが嵌り合ってその曲面部35の外周面に対して摺動するから、これらの単位チューブ31が連結されて構成された電線保護管10は、使用する場所に応じた形状に曲げることができる。即ち、可撓性を有し、かつ、強度の強い電線保護管10とすることができる。
According to this embodiment, the following effects can be obtained.
(1) By using the assembly jig 80, the plurality of unit tubes 31 are locked (held) at the time of assembly and do not become separated, so that the assembly of the wire protection tube 10 is facilitated. In addition, when assembling the electric wire protection tube 10 in which the electric wire 70 is not inserted into the divided unit tube 31 in the above assembly and the electric wire 70 is not inserted (when the electric wire 70 is inserted from one side of the electric wire protection tube 10 after the electric wire protection tube 10 is assembled). ) Can be easily assembled by using the assembly jig 80 as described above.
And if the electric wire 70 is inserted in such an electric wire protection tube 10, the electric wire 70 can be protected from the strong impact etc. from the outside. In addition, since the plurality of unit tubes 31 are fitted to the curved surface portion 35 of the unit tube 31 and the concave surface portion 37 of the unit tube 31 adjacent thereto and slide with respect to the outer peripheral surface of the curved surface portion 35, The electric wire protection tube 10 configured by connecting the unit tubes 31 can be bent into a shape corresponding to the place of use. That is, the electric wire protection tube 10 having flexibility and high strength can be obtained.

(2)分割単位チューブ31の凹状面部37には、係止孔37A(係止凹部)が設けられており、単位チューブ係止部は、係止孔37Aに嵌め込まれて係止される係止凸部84であるから、簡易な構成で分割単位チューブ31を保持部材81に係止させることができる。また、凹状面部37の外周に設けられる係止孔37Aは、保持部材81の側に凹部を設けるよりも比較的弾性変形しやすいから容易に係止凸部84を係止孔37Aに係止させることができる。 (2) The concave surface portion 37 of the divided unit tube 31 is provided with a locking hole 37A (locking recess), and the unit tube locking portion is locked by being fitted into the locking hole 37A. Since it is the convex part 84, the division | segmentation unit tube 31 can be latched to the holding member 81 with a simple structure. Further, since the locking hole 37A provided on the outer periphery of the concave surface portion 37 is relatively elastically deformed more easily than the concave portion provided on the holding member 81 side, the locking convex portion 84 is easily locked to the locking hole 37A. be able to.

(3)一対の保持部材81,81は、分割単位チューブ31の電線挿通孔が連なる方向に長い形状の底板部82(底部)とこの底板部82の両側縁から立ち上がる側壁部83,83とを有し、一方の保持部材81の側壁部83の上端部が他方の保持部材の側壁部の上端部に突き当てられることにより、各保持部材81に収容された分割単位チューブ31A,31A同士が嵌り合って電線保護管10が形成されるから、保持部材81同士を突き当てれば電線保護管10が組み立てられ、電線保護管10の組立が容易になる。 (3) The pair of holding members 81, 81 includes a bottom plate portion 82 (bottom portion) that is long in the direction in which the electric wire insertion holes of the divided unit tube 31 are continuous, and side wall portions 83, 83 that rise from both side edges of the bottom plate portion 82. And having the upper end portion of the side wall portion 83 of one holding member 81 abut against the upper end portion of the side wall portion of the other holding member, the divided unit tubes 31A and 31A accommodated in each holding member 81 are fitted to each other. Accordingly, since the electric wire protection tube 10 is formed, the electric wire protection tube 10 is assembled if the holding members 81 are brought into contact with each other, and the electric wire protection tube 10 is easily assembled.

(4)一方の保持部材81における側壁部83の上端部には、上方に突出する嵌合ピン85Aが形成されており、他方の保持部材81の側壁部83の上端部には、嵌合ピン85Aが挿入されるピン挿入凹部85Bが形成されているから、保持部材81,81同士を突き当てる際の位置合わせが容易になる。 (4) A fitting pin 85A protruding upward is formed at the upper end portion of the side wall portion 83 of one holding member 81, and the fitting pin is formed at the upper end portion of the side wall portion 83 of the other holding member 81. Since the pin insertion recess 85B into which 85A is inserted is formed, the positioning when the holding members 81 and 81 abut against each other becomes easy.

(5)単位チューブ31は、一対の分割単位チューブ31A,31Aのうちの一方に形成されたロック部38(ロックピン)が他方に形成されたロック孔39Aに挿入されて係止されるものであって、嵌合ピン85Aは、ロック部38がロック孔39Aに挿入されるのに先立って、ピン挿入凹部85Bに挿入されるから、ロック部38よりも嵌合ピン85Aが先に挿入されて位置合わせが行われることになり、ロック部38の損傷を防止することができる。 (5) The unit tube 31 is configured such that a lock portion 38 (lock pin) formed in one of the pair of divided unit tubes 31A and 31A is inserted into and locked in a lock hole 39A formed in the other. Since the fitting pin 85A is inserted into the pin insertion recess 85B before the lock portion 38 is inserted into the lock hole 39A, the fitting pin 85A is inserted before the lock portion 38. Positioning is performed, and damage to the lock portion 38 can be prevented.

(6)電線保護管10は、複数の単位チューブ31を連結して構成される連結単位チューブ30と、筒状プロテクタ部20と、連結単位チューブ30と筒状プロテクタ部20とを連結する連結部材41,48と、からなり、保持部材81,81のうち、電線保護管10の電線挿通孔が連なる方向の端部には、連結部材41,48に係止して連結部材41,48を位置決めする連結位置決め凹部86(位置決め部)が設けられている。
このように連結単位チューブ30と筒状プロテクタ部20とを有する場合に、これらの間を連結部材41,48で連結すれば、連結単位チューブ30と筒状プロテクタ部20との間の隙間による電線70の露出を防止することができるが、本構成によれば、この連結部材41,48を利用して、電線保護管10の組立の際の位置決めをすることができる。
(6) The electric wire protection tube 10 includes a connecting unit tube 30 configured by connecting a plurality of unit tubes 31, a cylindrical protector unit 20, and a connecting member that connects the connecting unit tube 30 and the cylindrical protector unit 20. 41, 48, and the end of the holding member 81, 81 in the direction in which the wire insertion hole of the wire protection tube 10 is connected is locked to the connection member 41, 48 to position the connection member 41, 48. A connecting positioning recess 86 (positioning portion) is provided.
Thus, when it has the connection unit tube 30 and the cylindrical protector part 20, if these are connected by the connection members 41 and 48, the electric wire by the clearance gap between the connection unit tube 30 and the cylindrical protector part 20 will be demonstrated. Although exposure of 70 can be prevented, according to this configuration, the connection members 41 and 48 can be used to position the wire protection tube 10 during assembly.

なお、可撓制を有しつつ電線70を保護するという点では、電線保護管10の全ての部分を連結単位チューブ30で構成することも可能であるが、連結単位チューブ30の部分については、可撓性を有するための構成により、筒状プロテクタ部20よりも体積が大きくなりやすく、その分重量が重くなりやすい。そこで、可撓性を有する必要のある部分については、連結単位チューブ30とし、可撓性を有する必要のない部分については、筒状プロテクタ部20により電線70を保護することとすれば、全てを連結単位チューブ30とする場合よりも電線保護管10を軽量化することができる。   In addition, in terms of protecting the electric wire 70 while having flexibility, it is possible to configure all the portions of the electric wire protection tube 10 with the connection unit tube 30, but for the portion of the connection unit tube 30, Due to the configuration for flexibility, the volume is likely to be larger than that of the cylindrical protector portion 20, and the weight is likely to increase accordingly. Therefore, if the portion that needs to be flexible is the connecting unit tube 30 and the portion that does not need to be flexible is to protect the electric wire 70 by the cylindrical protector portion 20, all of them are used. The wire protection tube 10 can be reduced in weight compared to the case where the connection unit tube 30 is used.

<実施形態2>
本発明の実施形態2を図25〜図31を参照して説明する。
実施形態1の組立治具80は、単位チューブ31や連結部材41,48を係止凸部84が係止した状態の解除を保持部材81,81を係止力に逆らって作業者が引き離すことにより行うこととしたが、実施形態2の組立治具80は、単位チューブ131や連結部材41,48の係止状態の解除を保持部材181,181がそれぞれ備える解除機構90により行うものである。以下、実施形態1と同一の構成については同一の符号を付して説明を省略する。
<Embodiment 2>
A second embodiment of the present invention will be described with reference to FIGS.
In the assembly jig 80 of the first embodiment, the operator pulls the holding members 81 and 81 against the locking force to release the state in which the locking projections 84 lock the unit tubes 31 and the connecting members 41 and 48. However, the assembly jig 80 of the second embodiment performs the release of the locked state of the unit tube 131 and the connecting members 41 and 48 by the release mechanism 90 provided in the holding members 181 and 181, respectively. Hereinafter, the same components as those of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

図31に示すように、単位チューブ131を構成する分割単位チューブ131Aの凹状面部137には、係止孔137Aが設けられている。
この係止孔137Aは、円形状の孔であって、単位チューブ131の内方側に向けて段差状に径が大きくなる段差部137Bを有する。
保持部材181,181は、金属製であって、その底板部182は、その幅方向の中心部に、解除機構90が収容された解除機構収容部103が設けられている。
As shown in FIG. 31, a locking hole 137 </ b> A is provided in the concave surface portion 137 of the divided unit tube 131 </ b> A constituting the unit tube 131.
The locking hole 137 </ b> A is a circular hole and has a step portion 137 </ b> B whose diameter increases stepwise toward the inner side of the unit tube 131.
The holding members 181 and 181 are made of metal, and the bottom plate portion 182 is provided with a release mechanism accommodation portion 103 in which the release mechanism 90 is accommodated at the center in the width direction.

解除機構収容部103は、底板部182を構成する上面部182Aと下面部182Bとの間の空間として設けられており、上面部182Aは、係止孔137Aの位置に対応して円形状に窪んだ収容凹部102を有する。
この収容凹部102の底面には、後述する係止片91A,91Aが挿通される挿通孔101が形成されている。
The release mechanism accommodating portion 103 is provided as a space between the upper surface portion 182A and the lower surface portion 182B constituting the bottom plate portion 182, and the upper surface portion 182A is recessed in a circular shape corresponding to the position of the locking hole 137A. It has an accommodating recess 102.
An insertion hole 101 through which locking pieces 91A and 91A described later are inserted is formed on the bottom surface of the housing recess 102.

解除機構90は、係止片91A,91Aが底板部182の上面部182Aから突き出されて単位チューブ131の係止孔137Aに係止可能となる係止状態(係止位置)と、係止片91A,91Aが底板部182側に引き戻されて係止状態が解除される解除状態(解除位置)とを切り換えるためのものである。
この解除機構90は、単位チューブ31や連結部材41,48の係止孔137Aに係止される単位チューブ係止部91と、作業者の操作に応じて単位チューブ係止部91を付勢する付勢部97とを有する。
The release mechanism 90 includes a locking state (locking position) in which the locking pieces 91 </ b> A and 91 </ b> A protrude from the upper surface part 182 </ b> A of the bottom plate part 182 and can be locked in the locking hole 137 </ b> A of the unit tube 131. 91A, 91A is pulled back to the bottom plate portion 182 side to switch the release state (release position) where the locked state is released.
The release mechanism 90 biases the unit tube locking portion 91 locked in the locking holes 137A of the unit tube 31 and the connecting members 41 and 48, and the unit tube locking portion 91 according to the operation of the operator. And an urging portion 97.

単位チューブ係止部91は、合成樹脂製であって、基端部から上方に枝分かれした一対の係止片91A,91Aを有し、この係止片91A,91Aの間はわずかに離間している。係止片91A,91Aの先端部は、半球型の係止球部とされ、分割単位チューブ131Aの係止の際には、この係止球部が係止孔137Aの段差部137Bに係止される(図29参照)。
単位チューブ係止部91の基端部には、幅方向に張り出した張出部91Dが形成されており、この張出部91Dと上面部182Aとの間に配されるバネ98により自然状態では単位チューブ係止部91が下方側に付勢されている。
The unit tube locking portion 91 is made of synthetic resin and has a pair of locking pieces 91A and 91A branched upward from the base end portion, and the locking pieces 91A and 91A are slightly separated from each other. Yes. The distal ends of the locking pieces 91A and 91A are hemispherical locking spheres, and when the divided unit tube 131A is locked, the locking spheres are locked to the stepped portion 137B of the locking hole 137A. (See FIG. 29).
A protruding portion 91D protruding in the width direction is formed at the base end portion of the unit tube locking portion 91, and in a natural state by a spring 98 disposed between the protruding portion 91D and the upper surface portion 182A. The unit tube locking portion 91 is urged downward.

付勢部97は、図26に示すように、底板部182の内部にて単位チューブ係止部91が載置される板状の載置板97Aと、載置板97Aと下面部182Bとの間に接続されるアーム部97Bと、を有する。   As shown in FIG. 26, the urging portion 97 includes a plate-like placement plate 97A on which the unit tube locking portion 91 is placed inside the bottom plate portion 182, and a placement plate 97A and a lower surface portion 182B. And an arm part 97B connected between them.

載置板97Aとアーム部97Bとの間の接続部分及びアーム部97Bと下面部182Bとの間の接続部分には、それぞれ接続部分を回動させるヒンジ97Cが設けられ、これにより、載置板97Aは、下側のヒンジ97Cを軸として、長手方向(分割チューブを並べる方向)に移動するようになっている。   Hinges 97C for rotating the connection portions are provided at the connection portion between the mounting plate 97A and the arm portion 97B and at the connection portion between the arm portion 97B and the lower surface portion 182B. 97A is configured to move in the longitudinal direction (direction in which the divided tubes are arranged) around the lower hinge 97C as an axis.

載置板97Aは、底板部182の外部に露出した把持部93に連なって構成されている。
把持部93は、作業者が掴むことができる棒状の部材であり、把持部93と底板部182の前端面182Cとの間には、弾性部材であるバネ95が設けられており、常時は、このバネ95により把持部93が手前側に付勢されている。
このときは、載置板97Aは、バネ95の弾性力により把持部93側に引き寄せられた係止位置(アーム97Bが下面部182Bに対して垂直に起立する位置)である。この係止位置にある載置板97Aの上に載置された単位チューブ係止部91は、バネ98により下方に付勢されているが、このバネ98よりも把持部93のバネ95の弾性力の方が大きいため、単位チューブ係止部91は、載置板97Aに弾性係止された状態で、底板部182の上面部182Aから突き出されている(突き出された係止片91A,91Aが分割単位チューブ31Aを係止可能な位置となる)。
ここから作業者がバネ95の弾性力に逆らって奥側(図26の右方)に把持部93を押し付けると、図27に示すように、アーム97Bが傾斜して載置板97Aが奥側に移動した解除位置となる。このとき、単位チューブ係止部91は、バネ98により下方側に付勢されているから載置板97Aとともに下方側に移動し、係止片91A,91Aが底板部182の内方に引き戻される(係止片91A,91Aの分割単位チューブ31Aへの係止が解除される位置となる)。
The mounting plate 97 </ b> A is configured to be connected to the grip portion 93 exposed to the outside of the bottom plate portion 182.
The grip portion 93 is a rod-shaped member that can be gripped by an operator, and a spring 95 that is an elastic member is provided between the grip portion 93 and the front end surface 182C of the bottom plate portion 182. The grip portion 93 is urged toward the front side by the spring 95.
At this time, the mounting plate 97A is a locking position (a position where the arm 97B stands perpendicular to the lower surface part 182B) drawn toward the grip portion 93 by the elastic force of the spring 95. The unit tube locking portion 91 mounted on the mounting plate 97 </ b> A in this locking position is biased downward by a spring 98, but the elasticity of the spring 95 of the gripping portion 93 is more than this spring 98. Since the force is larger, the unit tube locking portion 91 is protruded from the upper surface portion 182A of the bottom plate portion 182 while being elastically locked to the mounting plate 97A (the protruding locking pieces 91A, 91A). Is a position where the divided unit tube 31A can be locked).
When the operator presses the grip portion 93 against the back side (right side in FIG. 26) against the elastic force of the spring 95, the arm 97B is inclined and the mounting plate 97A is on the back side, as shown in FIG. The release position moved to. At this time, since the unit tube locking portion 91 is biased downward by the spring 98, the unit tube locking portion 91 moves downward together with the mounting plate 97A, and the locking pieces 91A and 91A are pulled back inward of the bottom plate portion 182. (This is the position at which the locking pieces 91A and 91A are unlocked from the divided unit tube 31A).

次に、組立治具80を用いた電線保護管110の組み立て方法について説明する。
最初に、両保持部材181,181の把持部93,93は、共に、バネ95により手前側に付勢されているから、両保持部材181,181の単位チューブ係止部91は係止位置となっている。
そして、一方の保持部材181について、分割連結部材41Aの係止孔137Aに一対の係止片91A,91Aを挿入して係止させる。そして、隣接する分割単位チューブ131Aについて順番に、係止孔137Aに一対の係止片91A,91Aを挿入して係止させていく。最後に分割連結部材48Aの係止孔137Aに一対の係止片91A,91Aを挿入して係止させたら、次に分割プロテクタ22を分割連結部材41A及び分割連結部材48Aにそれぞれ取り付ける。
Next, a method for assembling the wire protection tube 110 using the assembly jig 80 will be described.
First, since the grip portions 93 and 93 of both the holding members 181 and 181 are both urged toward the front side by the spring 95, the unit tube locking portion 91 of both the holding members 181 and 181 is in the locked position. It has become.
And about one holding member 181, a pair of latching pieces 91A and 91A are inserted and latched in the latching hole 137A of the division | segmentation connection member 41A. Then, a pair of locking pieces 91A and 91A are inserted into the locking holes 137A and locked in order for the adjacent divided unit tubes 131A. Finally, after the pair of locking pieces 91A and 91A are inserted and locked in the locking holes 137A of the split connection member 48A, the split protector 22 is then attached to the split connection member 41A and the split connection member 48A, respectively.

そして、電線挿通孔に電線70を配し、分割連結部材41A,48Aのそれぞれに取り付けられた分割プロテクタ22に、対をなす分割プロテクタ22を嵌め合わせて、分割プロテクタ22の被溶着部28を溶着して一体となった筒状プロテクタ部20とする。   And the electric wire 70 is distribute | arranged to the electric wire penetration hole, the division | segmentation protector 22 which makes a pair is fitted to the division | segmentation protector 22 attached to each of division | segmentation connection member 41A, 48A, and the welding part 28 of the division | segmentation protector 22 is welded. Thus, the cylindrical protector unit 20 is integrated.

次に、他方の保持部材181についても同様に、分割連結部材41A、複数の分割単位チューブ131A及び連結部材48Aを順番に係止孔137Aに一対の係止片91A,91Aを挿入して係止させる。
分割連結部材41A,48A及び複数の分割単位チューブ131Aを全て係止させたら、作業者は、当該他方の保持部材181を持ち上げて裏返す。このとき、複数の分割単位チューブ131Aや分割連結部材41A,48Aは、一対の係止片91A,91Aに係止されているから、抜け落ちない。
Next, similarly with respect to the other holding member 181, the divided connecting member 41A, the plurality of divided unit tubes 131A, and the connecting member 48A are sequentially inserted into the locking holes 137A and the pair of locking pieces 91A and 91A are locked. Let
When all of the divided connecting members 41A and 48A and the plurality of divided unit tubes 131A are locked, the operator lifts the other holding member 181 and turns it over. At this time, since the plurality of divided unit tubes 131A and the divided connecting members 41A and 48A are locked to the pair of locking pieces 91A and 91A, they do not fall off.

そして、一方の保持部材181と他方の保持部材181とを向き合わせ、嵌合ピン85Aがピン挿入凹部85Bに挿入されるように近づける。
嵌合ピン85Aがピン挿入凹部85Bに挿入されると、次に、ロック部38がロック孔39Aに近づき、ロック部38がロック孔39Aに挿入される。
Then, the one holding member 181 and the other holding member 181 are faced to approach each other so that the fitting pin 85A is inserted into the pin insertion recess 85B.
When the fitting pin 85A is inserted into the pin insertion recess 85B, the lock portion 38 then approaches the lock hole 39A, and the lock portion 38 is inserted into the lock hole 39A.

ロック部38がロック孔39Aに挿入されてロックされると、他方の保持部材181の側壁部83,83の上端部が、一方の保持部材181の側壁部83,83の上端部に突き当たる。   When the lock portion 38 is inserted into the lock hole 39A and locked, the upper end portions of the side wall portions 83 and 83 of the other holding member 181 abut against the upper end portions of the side wall portions 83 and 83 of the one holding member 181.

保持部材181の側壁部83,83が突き当たったら、次に、作業者は、上側と下側の保持部材181,181の把持部93,93を奥側に押し付ける。すると、載置板97Aが係止位置から前方の解除位置に移動して、一対の係止片91A,91A(を含む単位チューブ係止部91)が底板部82の内側に引かれ、全ての単位チューブ131について係止が解除される。
このときは、電線保護管110は、保持部材181,181(の単位チューブ係止部91に)全く係止されていないから、上側の保持部材181を持ち上げ、下側の保持部材181に残された電線保護管110を取り出す。
When the side wall portions 83 and 83 of the holding member 181 come into contact with each other, the operator then presses the grip portions 93 and 93 of the upper and lower holding members 181 and 181 to the back side. Then, the mounting plate 97A moves from the locking position to the forward release position, and the pair of locking pieces 91A, 91A (including the unit tube locking portion 91) is pulled inside the bottom plate portion 82, The unit tube 131 is unlocked.
At this time, since the wire protection tube 110 is not locked at all by the holding members 181 and 181 (to the unit tube locking portion 91), the upper holding member 181 is lifted and left on the lower holding member 181. Take out the wire protection tube 110.

このように、分割単位チューブ131Aの凹状面部37には、係止孔137Aが設けられており、単位チューブ係止部91の一対の係止片91A,91Aは、係止孔137Aの孔縁に係止するものであり、全ての単位チューブ係止部91の係止片91A,91Aがそれぞれ対応する係止孔137Aの孔縁に係止する係止位置から、全ての単位チューブ係止部91の係止片91A,91Aの係止孔137Aへの係止が解除される解除位置に変更可能な解除機構90を有する。したがって、解除機構90により、単位チューブ係止部91を係止位置から解除位置に移動させるだけで、係止片91A,91Aの係止が解除されるから、電線保護管110の組立後に保持部材181,181から電線保護管110を取り外す作業が容易になる。   Thus, the concave surface portion 37 of the divided unit tube 131A is provided with the locking hole 137A, and the pair of locking pieces 91A, 91A of the unit tube locking portion 91 are formed at the hole edge of the locking hole 137A. All the unit tube locking portions 91 are locked from the locking position where the locking pieces 91A, 91A of all the unit tube locking portions 91 are locked to the hole edges of the corresponding locking holes 137A. There is a release mechanism 90 that can be changed to a release position where the engagement of the engagement pieces 91A, 91A to the engagement hole 137A is released. Therefore, the locking mechanism 91 is released from the locking position by simply moving the unit tube locking portion 91 from the locking position to the releasing position by the release mechanism 90. Therefore, the holding member is assembled after the wire protection tube 110 is assembled. The operation of removing the electric wire protection tube 110 from 181 and 181 becomes easy.
