Description

【０００１】
【発明の属する技術分野】
本発明は電線保護部材の巻き付け方法及び巻き付け治具に関し、さらに詳しくは、自動車の電装品やその他のエレクトロニクス製品などに使用されている組電線を束ねる電線保護部材の巻き付け方法及び巻き付け治具に関する。
【０００２】
【従来技術】
従来より、自動車の電装品やその他の各種エレクトロニクス製品などには、周知のごとく配線を束ねた組電線がある。たとえば自動車に用いられている電装品には点火および始動回路以外に照明、信号、警告、充電、計器、ワイパーその他多種多様な回路があり、これらの回路を結ぶ電線類は極めて多くなり、組み電線として束ねられる。また、これらの電装品を接続する電線類は、高度に発達した流れ作業を採用している自動車製造工程に適合する様に一体の部品として前もって組立てられ使用されている。
【０００３】
従来、その電線の束ね方は、電線の端部にコネクタが接続された状態あるいは配線が完了した状態において、ビニールテープや粘着テープ等の電線保護部材を電線の束に巻きつけて固定する方法が多用されている。
しかしながら、多くの場合、数十本とある電線を粘着テープで巻き付け固定する作業は手間がかかる。そこで、図６に示すような比較的幅広い電線保護部材１０が用いられている。
【０００４】
図６に示す電線保護部材１０は、その一端に辺に沿って粘着部１５が設けられた矩形状のシート部材である。そして、この電線保護部材１０を巻き付けるときは、例えば、組電線２０の端部にコネクタ３０が取り付けられた状態において、先ず、図６の（ａ）に示すごとく、電線保護部材１０を、その粘着部１５が組電線２０の長手方向に沿うように対応させ、その後、図６の（ｂ）に示すように、粘着部１５設けられていない側の辺１２を先に巻き付けるように曲げ、該辺１２を押さえながら粘着部１５が設けられた側の辺１１を重ね合わせるようにし、最後に、辺１１に沿った部分の全域を手で上から擦るようにする。
このような操作によって、電線保護部材１０は、粘着部１５により、両辺１１、１２が接続され、図６の（ｃ）に示すように、場合によってはシワ１９等ができるものの、組電線２０を適宜束ねるとともに、所定な長さを保護できるように装着される。
【０００５】
この種の電線保護部材としては、種々の形態のものが提案されている。例えば、実開昭５４- １５９１７９号公報には、“一方端部と他端部とを嵌着して筒形にして電線束を束ねる電線集合体”が、実開昭５８- ８１９９０号公報には、“ビニールシート等のカバー素材の両端縁を重ね合わせて電線に巻回して、該電線を束ねるカバー部材”が、実開昭６０- ２１１１４号公報には、“熱収縮性フイルムの一端に粘着剤層を設けて電線束を束ねる結束用フイルム”が記載されている。
【０００６】
【発明が解決しようとする課題】
しかしながら、実開昭５４- １５９１７９号公報に記載された技術においては、端部同士の嵌着構造であるので、部材自身の構造が複雑なること、組電線の束の太さごとに合わせたサイズの電線保護部材が必要となるなど、極めて不経済である。
また、実開昭５８- ８１９９０号公報に記載された技術においては、図６に示した部材と同様に、比較的幅のあるシート状の電線保護部材を電線に巻き付ける作業であることから、電線長さ方向の長さが大きくなればなる程（保護領域が長い程）図１の（ｃ）に示すようなシワ１９等の巻ムラが発生し易く、巻き付け作業に多大な時間要する。特に、外気が低温の場合には、電線ならびに電線保護部材が硬化することから、巻き付け作業は極めて困難であった。
また、実開昭６０- ２１１１４号公報に記載された技術においては、熱収縮性のフィルムに素材が限定されるだけでなく、加熱工程とういう極めて面倒な作業工程を必要とし、また、加熱手段を必要とするなど、作業環境が限定される等の問題を抱えている。
【０００７】
本発明は、上記問題点に鑑みてなされたものであり、電線を束ねて組上げる際に、比較的長い領域を覆う電線保護部材であっても、巻きムラの発生を抑えることができ、巻き付けが容易にできる電線保護部材の巻き付け方法及び巻き付け治具を提供することを目的とする。
【０００８】
【課題を解決するための手段】
本発明に係る電線保護部材の巻き付け方法は、一端縁に沿って粘着部を有するシート状の電線保護部材を組電線上に巻き付けるときに、前記電線保護部材を、前記粘着部が前記組電線の長手方向に沿うように対応させた後、前記組電線と交差する一方の辺を、前記粘着部が他端縁側に接着可能な位置まで湾曲させる湾曲状態とし、その後、前記電線保護部材を前記組電線上にて前記湾曲状態に矯正可能な略筒形状の矯正手段を、先に前記湾曲状態とした側から反対側へ電線保護部材上を移動させることにより、前記電線保護部材の全体を前記湾曲状態にすることを特徴とし、これにより上記目的を達成することができる。
【０００９】
本発明に係る電線保護部材の巻き付け治具は、少なくとも内周面が略円筒形で、一端が組電線の外面から間隔をあけて該外面を囲むことができる大径内面を有し、該大径内面から他端に向かって連続し、前記組電線の直径に近づくように徐々に絞り込まれた小径内面を有することを特徴とし、これにより上記目的を達成することができる。
【００１０】
また、本発明に係る上記電線保護部材の巻き付け治具において、
・治具円周方向に対して略直交する縦方向の分割縁を有し、該分割縁の開閉を可能とするヒンジ部を有すること、
・前記分割縁には、該分割縁同士の係合を維持するロック機構を有すること、
・前記大径内面及び前記小径内面に対応して、傾斜する外面を有すること、
を特徴とする。
【００１１】
そして、本発明に係る上記電線保護部材の巻き付け方法によれば、一端縁に沿って粘着部を有するシート状の電線保護部材を組電線上に巻き付けるときに、前記一端縁を前記組電線に沿わせ、且つ前記組電線と交差する一方の辺において前記粘着部が他端縁に貼り付き可能な湾曲状態となることで、組電線上に巻き付けるための、巻き付け開始部分が形成される。
その後、前記電線保護部材を組電線を軽く包み込むような形状に湾曲させることのできる略筒形状の矯正手段（巻き付け治具）を、巻き付け開始部分側から該開始部分側とは反対側へ電線保護部材上を移動させる。この動作により、電線保護部材は、前記一端縁と他端縁とが巻き付け開始部分側から徐々に重なり合う湾曲状態（接着可能な位置まで湾曲した状態）となって行き、最終的に、電線保護部材全体を前記湾曲状態とすることができる。
【００１２】
また、本発明に係る上記電線保護部材の巻き付け治具によれば、一端が組電線の外面から間隔をあけて該外面を囲むことができる大径内面により、該大径内面側を先方にして移動させたときに、前記巻き付け開始部分側から、電線保護部材を該大径内面の内側に導入することができ、更に、この大径内面から他端に向かって連続しかつ徐々に絞り込まれた小径内面によって、前記電線保護部材の一端縁と他端縁（両端縁とも組電線に沿った端縁）とを接着可能な位置まで湾曲させることができる。
【００１３】
また、治具円周方向に対して略直交する縦方向の分割縁を有し、かつこの分割縁の開閉を可能とするヒンジ部を有する構成により、組電線が既に接続された場合や、組電線の端部にコネクタや機器類が接続された状態でも、巻き付け治具を組電線上のどの位置にも自由に装着することができる。
【００１４】
さらに、前記分割縁に、該分割縁同士の係合を維持するロック機構を有していることにより、巻き付け治具の閉じた状態を確実に維持することができる。
【００１５】
また、大径内面及び小径内面に対応して、傾斜する外面を有する構成により、該巻き付け治具を組電線に装着して該組電線上を移動させるときに、治具外面の傾斜に手指を引っかけるように操作することができ、操作上好都合である。
【００１６】
【発明の実施の形態】
以下、本発明に係る電線保護部材の巻き付け方法及び巻き付け治具の好適な実施の形態について図１〜図５を参照して詳細に説明する。
なお、図１は、本実施の形態の巻き付け治具を示す斜視図であり、図１の（ａ）は、巻き付け治具の開いた状態を示し、（ｂ）は閉じた状態を示す。図２、図３、図４は巻き付け方法を示す工程図であり、また、図５は図３に示す巻き付け工程に対応した一部断面概略図である。
【００１７】
図１に示す巻き付け治具１は、外観（図１の（ｂ）参照）並びに内周面において先細りの略円筒形状の部材であり、一端が比較的大径の挿入口４で、他端が小径の出口５を有している。そして、内側壁面はが、挿入口４側が組電線２０（図２参照）の外面から間隔をあけて該外面を囲むことができる大径内面２を有し、この大径内面２から他端（出口端５）に向かって徐々に絞り込まれた円錐内面が形成され、該円錐内面の出口５側が小径内面３として構成されている。
【００１８】
また、巻き付け治具１は、治具円周方向に対して略直交する縦方向（中心線Ｃに沿った方向）の分割縁６、７を有し、この分割縁６、７の開閉（矢印Ｙ方向の開閉）を可能とするヒンジ部８を有する。
【００１９】
また、本実施の形態における巻き付け治具１は、その素材に関しては、特に限定されるものではないが、例えばポリエチレンテレフタレート（ＰＥＴ）あるいはポリオキシメチレン（ＰＯＭ）等の合成樹脂材により構成することができる。このように、合成樹脂材により構成されることにより、例えばヒンジ部８は単に薄肉に構成するだけでよく、製造が極めて容易である。
【００２０】
また、本実施の形態の巻き付け治具１は、分割縁６、７に、該分割縁６、７同士の係合を維持するロック機構を有している。すなわち、例えば分割縁６側の外面に突起１６が形成され、一方、分割縁７側の外面には円周方向に沿って張り出した張り出し辺１７を有し、該張り出し辺１７の内側に突起１６と嵌合する凹部（図示せず）が形成されている。このロック機構により、巻き付け治具１の閉じた状態を確実に維持することができる。
【００２１】
本実施の形態における巻き付け治具１は、前掲のごとく外観においても、先細りの円錐形状である。すなわち、該治具１の外面８が、大径内面２及び小径内面３に対応して、傾斜する外面を有している。
したがって、この巻き付け治具１を使用するとき（組電線に装着した状態で該組電線に沿ってスライド操作するとき）、外面８の傾斜構造により、該治具１を把持し易い構造となっている。
【００２２】
以下、本発明に係る電線保護部材の巻き付け方法を、図２〜図５を参照して説明する。まず、図２の（ａ）に示すように、組電線２０の所定箇所（電線保護部材を巻き付ける位置或いはその近傍）に、巻き付け治具１を開いた状態から組電線２０を囲むように閉じて装着する（図２の（ｂ）参照）。
その後、一端縁１１に沿って粘着部１５を有する、例えば？等からなるシート状の電線保護部材１０を組電線２０に沿わせる（図２の（ｂ）参照）。このとき、電線保護部材１０を、その粘着部１５が組電線２０と平行になるようにし、その後、組電線２０と交差する一方の辺１３（巻き付け治具１が装着された側の辺）を該組電線２０を軽く包むように“の”字形状にする（図３の（ｃ）及び図５の（ｃ）参照）。
このとき、“の”字形状に巻いた部分は、粘着部１５と他端縁１２とは接着していない状態である。
【００２３】
その後、“の”字形状の部分を、巻き付け治具１の挿入口４側へ押し込む（矢印Ｚ方向への移動）。そして、治具１の出口５側から露出した“の字”形状の部分を図３及び図５の（ｄ）に示す矢印Ｍ方向へ引っ張りきつく巻き付け、片端部（辺１３）を指で押さえる。
ここで、辺１３の部分は、指で押さえることにより、他端縁１２の上に一端縁１１が粘着される。
【００２４】
その後、電線保護部材１の辺１３部分を指で押さえながら、巻き付け治具１を辺１３とは逆方向（矢印Ｘ方向）へスライドさせる。このスライドにより、図５の（ｄ）に示すように、電線保護部材１は、挿入口端４側の大径内面２により半巻き状態まで湾曲され、出口端５に向かって徐々に絞り込むような傾斜した小径内面３により、徐々に“の”字形状となる。
【００２５】
また、巻き付け治具１のスライド操作のときに、該治具１の出口端５側から現れてくる電線保護部材１０のところどころ（図３及び図５の（ｅ）に示すＡ，Ｂなどの粘着部１５が設けられた部分に対応した部分）を指で押さえながら、電線保護部材１０が該治具１から完全に露出するまで（電線保護部材１の終端の辺１４が治具１を通過するまで）該治具１をスライドさせる（図４の（ｆ）の状態）。
その後、巻き付け治具１を開いて組電線２０から外し、例えば手指５０により粘着確認の意味を兼ねて、もう一度上部材裏側の粘着部１５に対応した一端縁１１全体を指で押しつける。
【００２６】
本発明に係る巻き付け治具は、必要に応じて、例えば外観形状や内周面の形状等は円錐面の一部でなくてもよく適宜変更可能であることは勿論である。
また、本発明に係る巻き付け方法は、電線保護部材の一端（辺１３）を巻き付け治具に通すとき、前掲の実施の形態においては、電線保護部材を移動するようにしたが、該治具を移動するように操作してもよいことは勿論である。
【００２７】
【発明の効果】
以上説明したように、本発明に係る電線保護部材の巻き付け方法及び巻き付け治具によれば、該巻き付け治具を使用して、電線保護部材を組電線上への最終巻き付けの直前状態までに安定してセッティングすることができるので、電線保護部材の巻き付けにバラツキ（巻きムラ）が殆どなく、短時間で済み品質、作業性が向上する。
特に、本発明に係る電線保護部材の書き付け方法及び巻き付け治具によれば、電線保護部材が長くなればなるほど（組電線を保護する部位が長くなるばなるほど）その効果は顕著であり、また、低温期において、組電線や電線保護部材が比較的硬くなった状態において顕著な効果を発揮することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a winding method and a winding jig for an electric wire protection member, and more particularly to a winding method and a winding jig for an electric wire protection member for bundling assembled wires used in automobile electrical components and other electronic products.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there are assembled electric wires in which wiring is bundled as is well known in automobile electrical components and other various electronic products. For example, electrical components used in automobiles include a wide variety of circuits such as lighting, signals, warnings, charging, measuring instruments, wipers, etc., in addition to ignition and starting circuits. Bundled as In addition, the electric wires connecting these electrical components are pre-assembled and used as an integral part so as to be compatible with the automobile manufacturing process adopting highly developed flow work.
[0003]
Conventionally, the method of bundling the wires is to wrap and fix a wire protection member such as vinyl tape or adhesive tape around the bundle of wires when the connector is connected to the end of the wire or when the wiring is completed. It is used a lot.
However, in many cases, it takes time and effort to wind and fix several tens of wires with an adhesive tape. Therefore, a relatively wide wire protection member 10 as shown in FIG. 6 is used.
[0004]
The electric wire protection member 10 shown in FIG. 6 is a rectangular sheet member having an adhesive portion 15 provided along one side at one end thereof. And when winding this electric wire protection member 10, for example in the state where the connector 30 was attached to the edge part of the assembled electric wire 20, first, as shown to (a) of FIG. The portion 15 is made to correspond to the longitudinal direction of the assembled electric wire 20, and then, as shown in FIG. 6B, the side 12 on the side where the adhesive portion 15 is not provided is bent so as to be wound first, The side 11 on the side where the adhesive portion 15 is provided is overlapped while pressing 12, and finally, the entire region along the side 11 is rubbed from above by hand.
By such an operation, both sides 11 and 12 are connected to the electric wire protection member 10 by the adhesive portion 15 and, as shown in FIG. It is appropriately bundled and attached so that a predetermined length can be protected.
[0005]
Various types of wire protection members have been proposed. For example, Japanese Utility Model Laid-Open No. 54-159179 discloses “a wire assembly in which one end portion and the other end portion are fitted into a cylindrical shape to bundle a bundle of wires” in Japanese Utility Model Laid-Open No. 58-81990. “A cover member that wraps both ends of a cover material such as a vinyl sheet and winds it around an electric wire and bundles the electric wire” is disclosed in Japanese Utility Model Publication No. 60-21114 as “one end of a heat-shrinkable film”. "Bundling film" in which an adhesive layer is provided to bundle an electric wire bundle is described.
[0006]
[Problems to be solved by the invention]
However, in the technique described in Japanese Utility Model Publication No. 54-159179, since the end portions are fitted to each other, the structure of the member itself is complicated, and the size according to the thickness of the bundle of assembled wires It is extremely uneconomical, such as the need for a wire protection member.
Further, in the technique described in Japanese Utility Model Publication No. 58-81990, since the sheet-shaped wire protection member having a relatively wide width is wound around the electric wire in the same manner as the member shown in FIG. As the length in the length direction increases (the longer the protection area), the winding unevenness of the wrinkles 19 and the like as shown in FIG. 1C is likely to occur, and the winding operation takes a long time. In particular, when the outside air is at a low temperature, the wire and the wire protection member are cured, so that the winding operation is extremely difficult.
In the technique described in Japanese Utility Model Laid-Open No. 60-21114, not only is the material limited to the heat-shrinkable film, but also a very troublesome work process such as a heating process is required. The problem is that the working environment is limited.
[0007]
The present invention has been made in view of the above problems, and even when the wires are bundled and assembled, even if the wire protection member covers a relatively long region, the occurrence of winding unevenness can be suppressed, An object of the present invention is to provide a winding method and a winding jig for an electric wire protection member that can be easily performed.
[0008]
[Means for Solving the Problems]
In the winding method of the wire protection member according to the present invention, when the sheet-like wire protection member having an adhesive portion along one edge is wound on the assembled wire, the wire protection member is disposed on the assembled wire. After making it correspond along a longitudinal direction, let one side which cross | intersects the said assembled electric wire be in the curved state which curves to the position which the said adhesion part can adhere | attach to an other end edge side, Then, the said electric wire protection member is said assembly By moving the substantially cylindrical correction means that can be corrected to the curved state on the electric wire from the side previously set to the curved state to the opposite side, the entire electric wire protective member is bent. The above-mentioned purpose can be achieved.
[0009]
The winding jig for the wire protection member according to the present invention has a large-diameter inner surface that has at least an inner peripheral surface that is substantially cylindrical and has one end that can surround the outer surface with a space from the outer surface of the assembled wire. It has a small-diameter inner surface that is continuous from the inner diameter surface toward the other end and is gradually narrowed so as to approach the diameter of the assembled electric wire, thereby achieving the above object.
[0010]
Moreover, in the winding jig of the wire protection member according to the present invention,
-Having a longitudinally divided edge substantially perpendicular to the jig circumferential direction, and having a hinge portion that enables opening and closing of the divided edge;
-The split edge has a lock mechanism for maintaining the engagement between the split edges;
Having an inclined outer surface corresponding to the large-diameter inner surface and the small-diameter inner surface;
It is characterized by.
[0011]
According to the winding method of the wire protection member according to the present invention, when the sheet-like wire protection member having an adhesive portion along one end edge is wound on the assembled wire, the one end edge is aligned with the assembled wire. In addition, a winding start portion for winding on the assembled wire is formed by forming a curved state in which the adhesive portion can be attached to the other end edge on one side intersecting the assembled wire.
After that, the wire-protecting member (winding jig) capable of bending the wire protection member into a shape that gently wraps the assembled wire is protected from the winding start portion side to the opposite side to the start portion side. Move on the member. By this operation, the wire protection member becomes a curved state where the one end edge and the other end edge gradually overlap each other from the winding start portion side (a state where the wire protection member is bent to a position where it can be bonded). The whole can be in the curved state.
[0012]
Moreover, according to the winding jig for the wire protection member according to the present invention, the large-diameter inner surface can be surrounded by the large-diameter inner surface that can surround the outer surface with one end spaced from the outer surface of the assembled wire. When moved, the wire protection member can be introduced into the inner surface of the large-diameter inner surface from the winding start portion side, and further, it is continuously and gradually narrowed from the large-diameter inner surface toward the other end. With the small diameter inner surface, the one end edge and the other end edge of the electric wire protection member can be bent to a position where both end edges can be bonded together.
[0013]
In addition, when the assembled wire is already connected by the configuration having a vertical split edge substantially orthogonal to the jig circumferential direction and having a hinge portion that enables opening and closing of the split edge, Even when a connector or equipment is connected to the end portion of the electric wire, the winding jig can be freely attached to any position on the assembled electric wire.
[0014]
Furthermore, the closed state of the winding jig can be reliably maintained by having the lock mechanism for maintaining the engagement between the split edges at the split edges.
[0015]
In addition, with the configuration having the inclined outer surface corresponding to the large diameter inner surface and the small diameter inner surface, when the winding jig is mounted on the assembled wire and moved on the assembled wire, fingers are applied to the inclination of the outer surface of the jig. It can be operated so as to be hooked, which is convenient for operation.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a winding method of a wire protection member and a winding jig according to the present invention will be described in detail with reference to FIGS.
FIG. 1 is a perspective view showing the winding jig of the present embodiment. FIG. 1 (a) shows an open state of the winding jig and FIG. 1 (b) shows a closed state. 2, 3 and 4 are process diagrams showing a winding method, and FIG. 5 is a partial cross-sectional schematic view corresponding to the winding process shown in FIG.
[0017]
A winding jig 1 shown in FIG. 1 is a substantially cylindrical member that is tapered on an outer appearance (see FIG. 1B) and an inner peripheral surface, and has one end having a relatively large diameter insertion port 4 and the other end. It has a small diameter outlet 5. The inner wall surface has a large-diameter inner surface 2 on the insertion port 4 side that can surround the outer surface with a space from the outer surface of the assembled wire 20 (see FIG. 2). A conical inner surface gradually narrowed toward the outlet end 5) is formed, and the outlet 5 side of the conical inner surface is configured as a small-diameter inner surface 3.
[0018]
The winding jig 1 has split edges 6 and 7 in the vertical direction (direction along the center line C) substantially orthogonal to the jig circumferential direction, and the split edges 6 and 7 are opened and closed (arrows). It has a hinge portion 8 that enables opening and closing in the Y direction.
[0019]
Further, the winding jig 1 in the present embodiment is not particularly limited with respect to the material, but may be composed of a synthetic resin material such as polyethylene terephthalate (PET) or polyoxymethylene (POM). it can. Thus, by being comprised with a synthetic resin material, the hinge part 8 should just be comprised only thinly, for example, and manufacture is very easy.
[0020]
Further, the winding jig 1 of the present embodiment has a locking mechanism for maintaining the engagement between the divided edges 6 and 7 at the divided edges 6 and 7. That is, for example, the protrusion 16 is formed on the outer surface on the divided edge 6 side, while the outer surface on the divided edge 7 side has a projecting side 17 projecting along the circumferential direction, and the projection 16 is formed inside the projecting side 17. And a recess (not shown) to be fitted. By this lock mechanism, the closed state of the winding jig 1 can be reliably maintained.
[0021]
The winding jig 1 in the present embodiment has a tapered conical shape even in appearance as described above. That is, the outer surface 8 of the jig 1 has an inclined outer surface corresponding to the large-diameter inner surface 2 and the small-diameter inner surface 3.
Therefore, when this winding jig 1 is used (when it is slid along the assembled wire while attached to the assembled wire), the inclined structure of the outer surface 8 makes it easy to grip the jig 1. Yes.
[0022]
Hereinafter, the winding method of the electric wire protection member concerning this invention is demonstrated with reference to FIGS. First, as shown in FIG. 2 (a), the coiled wire 20 is closed at a predetermined position (position where the wire protection member is wound or in the vicinity thereof) so as to surround the coiled wire 20 from the opened state. Wear (see (b) of FIG. 2).
Then, it has the adhesion part 15 along the one end edge 11, for example,? A sheet-shaped wire protection member 10 made of, for example, is placed along the assembled wire 20 (see FIG. 2B). At this time, the adhesive portion 15 of the wire protection member 10 is made parallel to the assembled wire 20, and then one side 13 (side on which the winding jig 1 is mounted) intersecting the assembled wire 20 is arranged. The assembled electric wire 20 is formed in a ““ ”shape so as to be lightly wrapped (see FIG. 3C and FIG. 5C).
At this time, the adhesive portion 15 and the other end edge 12 are not bonded to each other in the portion wound in the shape of "".
[0023]
Thereafter, the “-”-shaped portion is pushed into the insertion port 4 side of the winding jig 1 (movement in the arrow Z direction). Then, the “letter” -shaped portion exposed from the outlet 5 side of the jig 1 is tightly wound in the direction of arrow M shown in FIGS. 3 and 5D, and one end (side 13) is pressed with a finger.
Here, the edge 13 is adhered to the other edge 12 by pressing the edge 13 with a finger.
[0024]
Thereafter, the winding jig 1 is slid in the direction opposite to the side 13 (arrow X direction) while pressing the side 13 portion of the wire protection member 1 with a finger. With this slide, as shown in FIG. 5 (d), the wire protection member 1 is bent to a half-winding state by the large-diameter inner surface 2 on the insertion port end 4 side and gradually narrows toward the outlet end 5. Due to the inclined small-diameter inner surface 3, it gradually becomes a ““ ”shape.

【The invention's effect】
As described above, according to the winding method and the winding jig of the wire protection member according to the present invention, the wire protection member can be stabilized up to the state immediately before the final winding on the assembled wire using the winding jig. Therefore, there is almost no variation (winding unevenness) in the winding of the wire protection member, and it takes only a short time and the quality and workability are improved.
In particular, according to the writing method and the winding jig of the electric wire protection member according to the present invention, the longer the electric wire protection member is (the longer the portion that protects the assembled electric wire is longer), the more remarkable the effect is. In the low temperature period, a remarkable effect can be exhibited in a state where the assembled wire and the wire protection member are relatively hard.
