Abstract

<P>PROBLEM TO BE SOLVED: To fix an electric wire with a sheathing tube without using a bundling band such as a tie wrap when cabling the electric wire with the sheathing tube such as a wire harness for a vehicle in which a wire is branched from a trunk wire to a protector. <P>SOLUTION: An electric wire fixing mechanism 10 composed of outlet port inside walls 11, a middle wall 12 and a guide wall 13 is arranged at a main body 2 of the protector. The electric wire 20 with the sheathing tube passes between the guide wall 13 and the root 12a of the middle wall 12, sneaks the tip 12b of the middle wall 12, between the outlet port inside walls 11 and the tip 12b of the middle wall 12, and after that, to be drawn out of an outlet port 9. When the electric wire 20 with the sheathing tube is pulled outwardly, the tip 12b of the middle wall 12 is oscillated toward the direction of an arrow A, and thus the electric wire 20 with the sheathing tube is sandwiched by the outlet port inside walls 11. By this, the electric wire 20 with the sheathing tube can be fixed without using the bundling band. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、幹線から枝線が分岐する車両用のワイヤーハーネスなどに適用するに好適な、プロテクタ、電線の配索方法および配索構造に関するものである。   The present invention relates to a protector, a wiring method, and a wiring structure that are suitable for use in a wire harness for a vehicle in which a branch line branches from a trunk line.

図７は従来のプロテクタを例示する斜視図、図８は図７のプロテクタに外装チューブ付き電線を配索する方法を示す斜視図である。   FIG. 7 is a perspective view illustrating a conventional protector, and FIG. 8 is a perspective view illustrating a method of routing an electric wire with an outer tube to the protector of FIG.

従来、この種のプロテクタ１においては、図７に示すように、外装チューブ付き電線用の出口９が本体２に形成されている。そして、このプロテクタ１に外装チューブ付き電線を配索する際には、コルゲート噛み込み構造と異なり、電線を容易に固定・寸法確保することができない。そこで、図８に示すように、タイラップなどの結束バンド４で外装チューブ付き電線２０をプロテクタ１の出口９に締め付けて固定していた（例えば、特許文献１参照）。
特開２００４−１５９５１号公報 Conventionally, in this type of protector 1, an outlet 9 for an electric wire with an exterior tube is formed in the main body 2 as shown in FIG. 7. And when routing the electric wire with an exterior tube to this protector 1, unlike a corrugated biting structure, an electric wire cannot be fixed and dimension secured easily. Then, as shown in FIG. 8, the electric wire 20 with an exterior tube was fastened and fixed to the exit 9 of the protector 1 with a binding band 4 such as a tie wrap (see, for example, Patent Document 1).
JP 2004-15951 A

しかし、これでは、結束バンド４の部品代がかかるばかりか、取付作業工数も多くなる。さらに、結束バンド４は、小さい部品であるため、特に量産時に管理が困難となる。   However, this not only costs for the parts of the binding band 4, but also increases the number of man-hours for mounting. Furthermore, since the binding band 4 is a small part, it becomes difficult to manage especially during mass production.

このような事情は、外装チューブ付き電線のみならず外装チューブなし電線についても同様である。   Such a situation is the same for not only an electric wire with an outer tube but also an electric wire without an outer tube.

本発明は、こうした課題を解決することが可能な、プロテクタ、電線の配索方法および配索構造を提供することを目的とする。   An object of this invention is to provide the protector, the wiring method of wiring, and a wiring structure which can solve such a subject.

まず、請求項１に係るプロテクタの発明では、電線が配索されるプロテクタであって、前記電線が外向きに引っ張られると、当該電線を挟持して固定する電線固定機構を備えていることを特徴とする。
また、請求項２に係るプロテクタの発明では、前記電線固定機構は、出口部内壁と、この出口部内壁側へ移動して当該出口部内壁との間に前記電線を挟持する中壁と、前記電線が前記中壁の先端を回り込むように案内するガイド壁とを含むことを特徴とする。
また、請求項３に係るプロテクタの発明では、前記中壁は、付根部を支点として撓む形で先端を前記出口部内壁側へ揺動自在に支持されていることを特徴とする。
また、請求項４に係る電線の配索方法の発明では、電線をプロテクタに配索する、電線の配索方法であって、前記電線が外向きに引っ張られると、当該電線が前記プロテクタの中壁と出口部内壁との間に挟持されて固定されるように当該電線を屈曲させて当該プロテクタの出口から引き出すことを特徴とする。
また、請求項５に係る電線の配索構造の発明では、電線がプロテクタに配索された、電線の配索構造であって、前記電線は、外向きに引っ張られると、当該電線が前記プロテクタの中壁と出口部内壁との間に挟持されて固定されるように屈曲して当該プロテクタの出口から引き出されていることを特徴とする。 First, in the protector invention according to claim 1, it is a protector in which an electric wire is routed, and includes an electric wire fixing mechanism that clamps and fixes the electric wire when the electric wire is pulled outward. Features.
Moreover, in the protector invention according to claim 2, the wire fixing mechanism includes an outlet inner wall, an inner wall that moves toward the outlet inner wall and sandwiches the electric wire between the outlet inner wall, And a guide wall for guiding the electric wire so as to wrap around the tip of the inner wall.
The protector according to claim 3 is characterized in that the inner wall is supported so as to be able to swing freely toward the inner wall side of the outlet portion so as to bend with the root portion as a fulcrum.
Further, in the invention of the electric wire arrangement method according to claim 4, the electric wire is arranged in the protector, and when the electric wire is pulled outward, the electric wire is placed in the protector. The electric wire is bent and pulled out from the outlet of the protector so as to be sandwiched and fixed between the wall and the inner wall of the outlet portion.
Further, in the invention of the wiring structure of the electric wire according to claim 5, the electric wire is arranged in a protector, and when the electric wire is pulled outward, the electric wire is connected to the protector. It bends so that it may be pinched | interposed and fixed between the inner wall and the exit part inner wall, and it is drawn out from the exit of the said protector.

本発明によれば、電線が外向きに引っ張られると、電線がプロテクタに挟持されて固定されることから、タイラップなどの結束バンドを使用することなく電線を固定することができる。その結果、結束バンドによる従来の方法と比べて、結束バンドの部品代および取付作業工数が削減され、結束バンドの管理が不要となる。   According to the present invention, when the electric wire is pulled outward, the electric wire is sandwiched and fixed by the protector, so that the electric wire can be fixed without using a binding band such as a tie wrap. As a result, compared to the conventional method using a binding band, the parts cost of the binding band and the number of installation work steps are reduced, and the management of the binding band becomes unnecessary.

しかも、電線の引張力の大小に応じて電線の挟持力が増減するので、引張力の大小を問わず広範に対処することが可能となる。   And since the clamping force of an electric wire increases / decreases according to the magnitude of the tensile force of an electric wire, it becomes possible to cope widely regardless of the magnitude of the tensile force.

また、電線が外向きに引っ張られない限り、電線に締付力が作用しないので、電線が常に締め付けられることによる弊害を未然に防ぐことができる。   In addition, since the tightening force does not act on the electric wire unless the electric wire is pulled outward, it is possible to prevent an adverse effect caused by the electric wire being always tightened.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

＜第１の実施形態＞
図１は本発明に係るプロテクタの第１の実施形態を示す斜視図、図２は図１のプロテクタの要部を示す斜視図、図３は図１のプロテクタの要部を示す図であって、（ａ）はその平面図、（ｂ）はその左側面図、（ｃ）はその正面図、図４は図１のプロテクタに外装チューブ付き電線を配索する方法を示す平面図である。 <First Embodiment>
1 is a perspective view showing a first embodiment of a protector according to the present invention, FIG. 2 is a perspective view showing a main part of the protector of FIG. 1, and FIG. 3 is a view showing a main part of the protector of FIG. (A) is the top view, (b) is the left side view, (c) is the front view, FIG. 4 is a top view which shows the method of routing the electric wire with an exterior tube to the protector of FIG.

プロテクタ１は、図１に示すように、樋状の本体２を有しており、本体２には蓋３が薄肉のヒンジ５を介して矢印Ｍ、Ｎ方向に１８０°回動自在に一体で成形されている。蓋３には２個の係止爪６が形成されており、本体２には、これらの係止爪６に対応する位置に２個の係止片７が形成されている。   As shown in FIG. 1, the protector 1 has a bowl-shaped main body 2, and a lid 3 is integrated with the main body 2 through a thin hinge 5 so as to be rotatable by 180 ° in the directions of arrows M and N. Molded. Two latching claws 6 are formed on the lid 3, and two latching pieces 7 are formed on the main body 2 at positions corresponding to these latching claws 6.

また、本体２の側面には、図１から図３までに示すように、出口９が形成されており、出口９の内側には電線固定機構１０が設けられている。この電線固定機構１０は、出口部内壁１１と、「へ」の字状の中壁１２と、ガイド壁１３とから構成されている。ここで、中壁１２は、その付根部１２ａを支点として撓む形で先端１２ｂを矢印Ａ方向、つまり出口部内壁１１側へ揺動自在に支持されている。また、ガイド壁１３は、中壁１２の付根部１２ａの内側に立設されている。   Further, as shown in FIGS. 1 to 3, an outlet 9 is formed on the side surface of the main body 2, and an electric wire fixing mechanism 10 is provided inside the outlet 9. The electric wire fixing mechanism 10 includes an outlet inner wall 11, an “U” -shaped inner wall 12, and a guide wall 13. Here, the middle wall 12 is supported so that the tip 12b can swing in the direction of arrow A, that is, toward the inner wall 11 side of the outlet portion, with the root portion 12a as a fulcrum. The guide wall 13 is erected on the inner side of the root portion 12 a of the middle wall 12.

プロテクタ１は以上のような構成を有するので、ＰＶＣ（ポリ塩化ビニル）チューブなどの外装チューブが電線に外装された外装チューブ付き電線２０をプロテクタ１に配索する際には、図４に示すように、プロテクタ１内で外装チューブ付き電線２０を屈曲させる。このとき、外装チューブ付き電線２０は、ガイド壁１３と中壁１２の付根部１２ａとの間を通し、中壁１２の先端１２ｂを回り込ませて、出口部内壁１１と中壁１２の先端１２ｂとの間を通した後、出口９から引き出す。その後、蓋３を矢印Ｎ方向に１８０°回動させて閉じる。ここで、外装チューブ付き電線２０の配索作業が終了する。   Since the protector 1 has the above-described configuration, when the electric wire 20 with the outer tube in which the outer tube such as a PVC (polyvinyl chloride) tube is covered with the electric wire is routed to the protector 1, as shown in FIG. Next, the electric wire 20 with the outer tube is bent in the protector 1. At this time, the outer tube-attached electric wire 20 passes between the guide wall 13 and the root portion 12a of the middle wall 12 and wraps around the front end 12b of the middle wall 12 so that the outlet inner wall 11 and the front end 12b of the middle wall 12 After passing through, it pulls out from the exit 9. Thereafter, the lid 3 is turned 180 ° in the direction of arrow N and closed. Here, the wiring work of the electric wire 20 with the exterior tube is completed.

そして、外装チューブ付き電線２０が外向きに引っ張られると、電線固定機構１０により、プロテクタ１の中壁１２は、図４に示すように、その付根部１２ａを支点として撓む形で先端１２ｂを矢印Ａ方向、つまり出口部内壁１１側へ揺動させるため、外装チューブ付き電線２０は、中壁１２の先端１２ｂと出口部内壁１１との間に挟持される形でプロテクタ１に固定される。したがって、タイラップなどの結束バンド４を使用することなく外装チューブ付き電線２０を固定することができる。その結果、結束バンド４を使用する従来の方法（図８参照）と比べて、結束バンド４の部品代および取付作業工数が削減され、結束バンド４の管理が不要となる。   Then, when the outer tube-equipped electric wire 20 is pulled outward, the inner wall 12 of the protector 1 is bent by the electric wire fixing mechanism 10 with its root 12a as a fulcrum as shown in FIG. In order to swing in the direction of arrow A, that is, toward the outlet inner wall 11 side, the outer tube-attached electric wire 20 is fixed to the protector 1 so as to be sandwiched between the front end 12b of the middle wall 12 and the outlet inner wall 11. Therefore, the electric wire 20 with an exterior tube can be fixed without using the binding band 4 such as a tie wrap. As a result, compared to the conventional method using the binding band 4 (see FIG. 8), the cost of parts of the binding band 4 and the number of mounting work steps are reduced, and the management of the binding band 4 becomes unnecessary.

しかも、結束バンド４によって一定の力で外装チューブ付き電線２０を締め付ける従来の方法と異なり、外装チューブ付き電線２０の引張力が増大すると、それに応じて中壁１２の撓み量が大きくなり、外装チューブ付き電線２０の挟持力が増大する。逆に、外装チューブ付き電線２０の引張力が減少すると、それに応じて中壁１２の撓み量が小さくなり、外装チューブ付き電線２０の挟持力が減少する。したがって、外装チューブ付き電線２０の引張力の大小を問わず広範に対処することが可能となる。   In addition, unlike the conventional method of fastening the outer tube-equipped electric wire 20 with a certain force by the binding band 4, when the tensile force of the outer tube-equipped electric wire 20 increases, the amount of deflection of the inner wall 12 increases accordingly, and the outer tube The clamping force of the attached electric wire 20 increases. On the contrary, if the tensile force of the electric wire 20 with an exterior tube decreases, the amount of bending of the inner wall 12 will decrease accordingly, and the clamping force of the electric wire 20 with an exterior tube will decrease. Therefore, it is possible to deal with a wide range regardless of the tensile force of the electric wire 20 with the outer tube.

また、外装チューブ付き電線２０を外向きに引っ張る荷重がなくなると、それまで出口部内壁１１との間に外装チューブ付き電線２０を挟持していた中壁１２の先端１２ｂが、出口部内壁１１から離れて元の位置に戻る。したがって、結束バンド４で外装チューブ付き電線２０を締め付け続ける従来の方法と異なり、外装チューブ付き電線２０を締め付け続けない。すなわち、外装チューブ付き電線２０が外向きに引っ張られない限り、外装チューブ付き電線２０に締付力が作用しない。その結果、外装チューブ付き電線２０が常に締め付けられることによる弊害（例えば、電線と外装チューブとの摩擦、外装チューブの損傷など）を未然に回避することができる。   Further, when the load for pulling the outer tube-attached electric wire 20 outward is eliminated, the tip 12b of the inner wall 12 that has held the outer tube-attached electric wire 20 between the outer tube 11 and the outlet portion inner wall 11 until then is removed from the outlet portion inner wall 11. Move away and return to the original position. Therefore, unlike the conventional method in which the cable 20 with the outer tube is continuously tightened with the binding band 4, the electric wire 20 with the outer tube is not continuously tightened. In other words, unless the electric wire 20 with the outer tube is pulled outward, the tightening force does not act on the electric wire 20 with the outer tube. As a result, adverse effects (for example, friction between the electric wire and the outer tube, damage to the outer tube, etc.) due to the electric wire 20 with the outer tube being always tightened can be avoided.

さらに、中壁１２は、その付根部１２ａを支点として撓む形で先端１２ｂを出口部内壁１１側へ揺動自在に支持されているので、タイラップなどの結束バンドを使用した場合と違い、本体２と蓋３が係止爪６と係止片７により閉じられるまでであれば、外装チューブ付き電線２０の出し入れが可能である。   Further, the inner wall 12 is supported by the tip 12b so as to be swingable toward the outlet inner wall 11 side so as to bend with its root portion 12a as a fulcrum. Therefore, unlike the case where a binding band such as a tie wrap is used, As long as 2 and the lid 3 are closed by the locking claws 6 and the locking pieces 7, the outer tube-equipped electric wire 20 can be taken in and out.

＜第２の実施形態＞
図５は本発明に係るプロテクタの第２の実施形態を示す斜視図であって、（ａ）はその組付状態図、（ｂ）はその分解状態図、図６は図５のプロテクタに外装チューブ付き電線を配索する方法を示す斜視図であって、（ａ）はその第１工程図、（ｂ）はその第２工程図、（ｃ）はその第３工程図である。 <Second Embodiment>
5A and 5B are perspective views showing a second embodiment of the protector according to the present invention, wherein FIG. 5A is an assembled state diagram, FIG. 5B is an exploded state diagram, and FIG. 6 is an exterior view of the protector of FIG. It is a perspective view which shows the method of routing the electric wire with a tube, Comprising: (a) is the 1st process drawing, (b) is the 2nd process drawing, (c) is the 3rd process drawing.

プロテクタ１は、図５に示すように、本体２を有しており、本体２には蓋３が嵌合自在に別体で設けられている。   As shown in FIG. 5, the protector 1 has a main body 2, and a lid 3 is provided separately on the main body 2 so as to be freely fitted.

ここで、本体２の側面には、図５（ｂ）に示すように、中壁１２が薄肉のヒンジ８を介して矢印Ｋ、Ｌ方向に回動自在に連設されており、中壁１２の内側には、電線受け１７が付設されている。なお、中壁１２は、可動ピン（図示せず）を用いて閉状態で仮固定できるようになっている。また、本体２の側面には、ガイド壁１３および係合片１５が形成されている。さらに、本体２には係合突起１８が立設されている。   Here, as shown in FIG. 5B, the middle wall 12 is connected to the side surface of the main body 2 via the thin hinge 8 so as to be rotatable in the directions of arrows K and L. An electric wire receiver 17 is attached to the inside of the. The inner wall 12 can be temporarily fixed in a closed state using a movable pin (not shown). A guide wall 13 and an engagement piece 15 are formed on the side surface of the main body 2. Further, an engagement protrusion 18 is erected on the main body 2.

一方、蓋３の側面には、図５（ｂ）に示すように、下部がテーパ状に広がる出口９が形成されており、出口９の内側には出口部内壁１１が形成されている。また、蓋３の側面には、本体２の係合片１５に対応する位置に係合爪１６が形成されている。   On the other hand, as shown in FIG. 5B, the side surface of the lid 3 is formed with an outlet 9 having a tapered lower portion, and an outlet inner wall 11 is formed inside the outlet 9. An engaging claw 16 is formed on the side surface of the lid 3 at a position corresponding to the engaging piece 15 of the main body 2.

そして、本体２の中壁１２およびガイド壁１３と蓋３の出口部内壁１１とにより、電線固定機構１０が構成されている。   The wire fixing mechanism 10 is configured by the inner wall 12 and the guide wall 13 of the main body 2 and the outlet inner wall 11 of the lid 3.

プロテクタ１は以上のような構成を有するので、ＰＶＣ（ポリ塩化ビニル）チューブなどの外装チューブが電線に外装された外装チューブ付き電線２０をプロテクタ１に配索する際には、次の手順による。   Since the protector 1 has the above-described configuration, the following procedure is used when routing the wire 20 with the exterior tube in which the exterior tube such as a PVC (polyvinyl chloride) tube is sheathed on the wire.

まず、図６（ａ）に示すように、本体２の中壁１２が開いた状態で、外装チューブ付き電線２０を中壁１２の内側に載置する。   First, as illustrated in FIG. 6A, the electric wire 20 with the exterior tube is placed inside the middle wall 12 with the middle wall 12 of the main body 2 being opened.

次いで、図６（ｂ）に示すように、本体２の中壁１２を矢印Ｌ方向に９０°回動させて閉じ、前記可動ピンで中壁１２を仮固定する。このとき、外装チューブ付き電線２０は、電線受け１７に支持された状態となっているので、中壁１２から離れて脱落する恐れはない。   Next, as shown in FIG. 6B, the middle wall 12 of the main body 2 is closed by turning 90 ° in the direction of arrow L, and the middle wall 12 is temporarily fixed with the movable pin. At this time, since the outer tube-attached electric wire 20 is supported by the electric wire receiver 17, there is no possibility that the outer tube-attached electric wire 20 is detached from the inner wall 12.

最後に、図６（ｃ）に示すように、本体２に蓋３を嵌合させる。このとき、外装チューブ付き電線２０は、中壁１２の先端１２ｂを回り込ませて、出口部内壁１１と中壁１２の先端１２ｂとの間を通した後、出口９から引き出す。すると、蓋３の係合爪１６が本体２の係合片１５に係合する。また、出口９の下部が係合突起１８に係合する。このとき、出口９は、下部がテーパ状に広がっているため、係合突起１８との係合は円滑に行われる。   Finally, as shown in FIG. 6C, the lid 3 is fitted to the main body 2. At this time, the outer tube-attached electric wire 20 wraps around the front end 12 b of the middle wall 12, passes between the outlet portion inner wall 11 and the front end 12 b of the middle wall 12, and then is pulled out from the outlet 9. Then, the engaging claw 16 of the lid 3 engages with the engaging piece 15 of the main body 2. Further, the lower portion of the outlet 9 is engaged with the engaging protrusion 18. At this time, since the lower portion of the outlet 9 is tapered, the engagement with the engagement protrusion 18 is smoothly performed.

ここで、外装チューブ付き電線２０の配索作業が終了する。   Here, the wiring work of the electric wire 20 with the exterior tube is completed.

そして、外装チューブ付き電線２０が外向きに引っ張られると、上述した第１の実施形態と同様、電線固定機構１０により、外装チューブ付き電線２０は、中壁１２の先端１２ｂと出口部内壁１１との間に挟持される形でプロテクタ１に固定される。したがって、タイラップなどの結束バンド４を使用することなく外装チューブ付き電線２０を固定することができる。その結果、結束バンド４を使用する従来の方法（図８参照）と比べて、結束バンド４の部品代および取付作業工数が削減され、結束バンド４の管理が不要となる。   When the outer tube-attached electric wire 20 is pulled outward, the electric wire fixing mechanism 10 causes the outer tube-equipped electric wire 20 to be connected to the distal end 12b of the inner wall 12 and the outlet portion inner wall 11 as in the first embodiment described above. It is fixed to the protector 1 so as to be sandwiched between the two. Therefore, the electric wire 20 with an exterior tube can be fixed without using the binding band 4 such as a tie wrap. As a result, compared to the conventional method using the binding band 4 (see FIG. 8), the cost of parts of the binding band 4 and the number of mounting work steps are reduced, and the management of the binding band 4 becomes unnecessary.

しかも、結束バンド４によって一定の力で外装チューブ付き電線２０を締め付ける従来の方法と異なり、外装チューブ付き電線２０の引張力が増大すると、それに応じて中壁１２の撓み量が大きくなり、外装チューブ付き電線２０の挟持力が増大する。逆に、外装チューブ付き電線２０の引張力が減少すると、それに応じて中壁１２の撓み量が小さくなり、外装チューブ付き電線２０の挟持力が減少する。したがって、外装チューブ付き電線２０の引張力の大小を問わず広範に対処することが可能となる。   In addition, unlike the conventional method of fastening the outer tube-equipped electric wire 20 with a certain force by the binding band 4, when the tensile force of the outer tube-equipped electric wire 20 increases, the amount of deflection of the inner wall 12 increases accordingly, and the outer tube The clamping force of the attached electric wire 20 increases. On the contrary, if the tensile force of the electric wire 20 with an exterior tube decreases, the amount of bending of the inner wall 12 will decrease accordingly, and the clamping force of the electric wire 20 with an exterior tube will decrease. Therefore, it is possible to deal with a wide range regardless of the tensile force of the electric wire 20 with the outer tube.

また、外装チューブ付き電線２０を外向きに引っ張る荷重がなくなると、それまで出口部内壁１１との間に外装チューブ付き電線２０を挟持していた中壁１２の先端１２ｂが、出口部内壁１１から離れて元の位置に戻る。したがって、結束バンド４で外装チューブ付き電線２０を締め付け続ける従来の方法と異なり、外装チューブ付き電線２０を締め付け続けない。すなわち、外装チューブ付き電線２０が外向きに引っ張られない限り、外装チューブ付き電線２０に締付力が作用しない。その結果、外装チューブ付き電線２０が常に締め付けられることによる弊害（例えば、電線と外装チューブとの摩擦、外装チューブの損傷など）を未然に回避することができる。   Further, when the load for pulling the outer tube-attached electric wire 20 outward is eliminated, the tip 12b of the inner wall 12 that has held the outer tube-attached electric wire 20 between the outer tube 11 and the outlet portion inner wall 11 until then is removed from the outlet portion inner wall 11. Move away and return to the original position. Therefore, unlike the conventional method in which the cable 20 with the outer tube is continuously tightened with the binding band 4, the electric wire 20 with the outer tube is not continuously tightened. In other words, unless the electric wire 20 with the outer tube is pulled outward, the tightening force does not act on the electric wire 20 with the outer tube. As a result, adverse effects (for example, friction between the electric wire and the outer tube, damage to the outer tube, etc.) due to the electric wire 20 with the outer tube being always tightened can be avoided.

さらに、中壁１２は、ヒンジ８を介して回動自在に設けられているので、上述した第１の実施形態と比べ、小さな荷重により、外装チューブ付き電線２０を外向きに引っ張った場合でも、中壁１２が容易に可動し、電線固定機構１０が機能するという利点がある。   Furthermore, since the inner wall 12 is rotatably provided via the hinge 8, even when the outer tube-attached electric wire 20 is pulled outward with a small load compared to the first embodiment described above, There is an advantage that the middle wall 12 is easily movable and the electric wire fixing mechanism 10 functions.
