Description

本発明は、筒状のコルゲートチューブの端部と、該コルゲートチューブに挿通された電線の露出部と、がテープ巻きされたコルゲートチューブのテープ巻き構造に関するものである。   The present invention relates to a tape winding structure of a corrugated tube in which an end portion of a cylindrical corrugated tube and an exposed portion of an electric wire inserted through the corrugated tube are tape-wound.

一般に、車両に配索されるワイヤハーネスは、筒状のコルゲートチューブと、コルゲートチューブに挿通される電線と、を有し、コルゲートチューブの端部と電線の露出部とがテープ巻きされて互いに固定される。しかしながら、コルゲートチューブの内径と電線の外径とに差がある場合、コルゲートチューブの内周面と電線の外周面との間に隙間が形成されてしまい、このような状態でテープ巻きすると固定力が弱くなってしまうことがあった。   Generally, a wire harness routed in a vehicle has a tubular corrugated tube and an electric wire inserted through the corrugated tube, and the end portion of the corrugated tube and the exposed portion of the electric wire are taped and fixed to each other. Is done. However, if there is a difference between the inner diameter of the corrugated tube and the outer diameter of the electric wire, a gap is formed between the inner peripheral surface of the corrugated tube and the outer peripheral surface of the electric wire. Sometimes became weak.

そこで、コルゲートチューブのスリットにテープを通すテープ巻き方法が提案されている（例えば、特許文献１参照）。特許文献１に記載されたテープ巻き方法では、テープを、電線の外周に巻き付けた後、コルゲートチューブの内側から外側に向かうようにコルゲートチューブのスリットに通し、コルゲートチューブの外周に巻き付ける。このようにテープを巻き付けることで、コルゲートチューブを電線の外径に合わせて縮径させ、コルゲートチューブの内周面と電線の外周面との隙間を小さくすることにより、固定力の向上を図っている。   Therefore, a tape winding method in which the tape is passed through the slit of the corrugated tube has been proposed (for example, see Patent Document 1). In the tape winding method described in Patent Document 1, after winding the tape around the outer periphery of the electric wire, the tape is passed through the slit of the corrugated tube so as to go from the inside to the outside of the corrugated tube, and then wound around the outer periphery of the corrugated tube. By winding the tape in this way, the corrugated tube is reduced in diameter according to the outer diameter of the electric wire, and the gap between the inner peripheral surface of the corrugated tube and the outer peripheral surface of the electric wire is reduced, thereby improving the fixing force. Yes.

特開２０１５−１４６６７２号公報JP2015-146672A

しかしながら、特許文献１に記載のテープ巻き方法は、電線にテープを巻き付ける工程と、スリットにテープを通す工程と、コルゲートチューブにテープを巻き付ける工程と、をそれぞれ独立に実施しなければならず、作業が複雑であるとともに作業時間が長時間化しやすいという不都合があった。即ち、テープ巻き作業を効率化（例えば自動化）することが困難であった。   However, in the tape winding method described in Patent Document 1, the step of winding the tape around the electric wire, the step of passing the tape through the slit, and the step of winding the tape around the corrugated tube must be performed independently. However, there are inconveniences that the working time tends to be long. That is, it is difficult to improve the efficiency (for example, automate) the tape winding operation.

本発明の目的は、固定力を向上させつつテープ巻き作業を効率化することができるコルゲートチューブのテープ巻き構造を提供することにある。   The objective of this invention is providing the tape winding structure of the corrugated tube which can improve a tape winding operation | work efficiently, improving a fixing force.

前記課題を解決し目的を達成するために、請求項１に記載された発明は、筒状のコルゲートチューブの端部と、該コルゲートチューブに挿通された電線の露出部と、がテープ巻きされたコルゲートチューブのテープ巻き構造であって、前記コルゲートチューブの両端には、軸方向に沿って延びる一対の縁部を有する樋状の突出部が形成され、前記コルゲートチューブの一端側の前記突出部と他端側の前記突出部とが軸方向から見て重ならない位置に形成されていることを特徴とするコルゲートチューブである。 In order to solve the above problems and achieve the object, the invention described in claim 1 is characterized in that an end portion of a cylindrical corrugated tube and an exposed portion of an electric wire inserted through the corrugated tube are wound with tape. A tape winding structure of a corrugated tube, wherein both ends of the corrugated tube are formed with hook-shaped protrusions having a pair of edges extending along the axial direction, and the protruding part on one end side of the corrugated tube The corrugated tube is characterized in that it is formed at a position where the protruding portion on the other end side does not overlap when viewed from the axial direction .

請求項２に記載された発明は、請求項１に記載の発明において、前記コルゲートチューブは円筒状に形成され、前記突出部が半円状の断面を有することを特徴とするものである。   The invention described in claim 2 is characterized in that, in the invention described in claim 1, the corrugated tube is formed in a cylindrical shape, and the protruding portion has a semicircular cross section.

請求項３に記載された発明は、請求項１又は２に記載の発明において、前記コルゲートチューブは、軸方向に沿って延びるスリット部を有し、前記一対の縁部のうち一方は、前記スリット部に連続して形成されていることを特徴とするものである。   The invention described in claim 3 is the invention according to claim 1 or 2, wherein the corrugated tube has a slit portion extending along an axial direction, and one of the pair of edge portions is the slit. It is characterized by being formed continuously in the part.

請求項１記載の発明によれば、コルゲートチューブが樋状の突出部を有することで、突出部に位置づけられた電線は、周方向のうち一部が突出部によって覆われ、他の部分が露出部となる。このようなコルゲートチューブの突出部と電線の露出部とをまとめてテープ巻きすることができ、固定力を向上させることができる。このとき、コルゲートチューブを電線に合わせて変形させるための特別な工程は必要なく、単にテープを巻き付けるだけでよいため、テープ巻き作業を効率化することができる。尚、テープ巻き時に、巻き付ける力によって突出部が電線に合わせて多少変形してもよいし、変形しなくてもよい。また、両端に突出部を有するコルゲートチューブを、容易に複数本製造することができる。即ち、一端に突出部を有する筒状部材を、軸方向から見て一端の突出部と重ならない突出部を他端に形成するように、切断することによって第１のコルゲートチューブを形成する。このとき、筒状部材には、第１のコルゲートチューブの一端と同様の突出部が形成される。同様に他端に突出部を形成するように筒状部材を切断すれば、第２のコルゲートチューブを形成することができる。このように、一種類の切断作業を繰り返すことで、両端に突出部を有する複数本のコルゲートチューブを容易に製造することができる。 According to the first aspect of the invention, since the corrugated tube has the hook-shaped protrusion, the electric wire positioned in the protrusion is partially covered by the protrusion in the circumferential direction, and the other part is exposed. Part. Such a protruding portion of the corrugated tube and the exposed portion of the electric wire can be taped together, and the fixing force can be improved. At this time, a special process for deforming the corrugated tube according to the electric wire is not necessary, and it is only necessary to wind the tape, so that the tape winding operation can be made efficient. In addition, at the time of tape winding, a protrusion part may change a little according to an electric wire with the force to wind, and does not need to change. In addition, a plurality of corrugated tubes having protrusions at both ends can be easily manufactured. That is, the first corrugated tube is formed by cutting a cylindrical member having a protruding portion at one end so that a protruding portion that does not overlap with the protruding portion at one end when viewed in the axial direction is formed at the other end. At this time, the cylindrical member is formed with a projection similar to one end of the first corrugated tube. Similarly, the second corrugated tube can be formed by cutting the cylindrical member so as to form a protrusion at the other end. Thus, by repeating one type of cutting operation, a plurality of corrugated tubes having protrusions at both ends can be easily manufactured.

請求項２に記載の発明によれば、筒状部材を切断して適宜な長さのコルゲートチューブを得る際に、突出部が半円状の断面を有するように切断することにより、筒状部材の余剰側にも同様の突出部が形成される。この筒状部材の余剰側を、同様の突出部を有するコルゲートチューブとすることができる。即ち、１回の切断によって、同様の突出部を２本のコルゲートチューブに形成することができる。   According to the invention described in claim 2, when the corrugated tube having an appropriate length is obtained by cutting the tubular member, the projecting portion is cut so as to have a semicircular cross section. Similar protrusions are also formed on the surplus side. The surplus side of this cylindrical member can be a corrugated tube having a similar protruding portion. That is, the same protrusion can be formed in two corrugated tubes by one cutting.

請求項３記載の発明によれば、樋状の突出部の一方の縁部がスリット部と連続していることで、この縁部を形成するためにコルゲートチューブを切断する必要がなく、切断作業の工程を削減したり切断手段を簡素化したりすることができる。   According to the third aspect of the present invention, since one edge portion of the bowl-shaped projecting portion is continuous with the slit portion, there is no need to cut the corrugated tube in order to form this edge portion. This process can be reduced and the cutting means can be simplified.

以下、本発明の実施形態を図面に基づいて説明する。図１は、実施形態に係るワイヤハーネス１を示す斜視図であり、図２は、ワイヤハーネス１のコルゲートチューブ２を示す斜視図であり、図３は、コルゲートチューブ２を示す正面図であり、図４は、コルゲートチューブ２を製造するための製造装置１００を示す斜視図であり、図５は、製造装置１００によってコルゲートチューブを製造する様子を示す下面図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a wire harness 1 according to the embodiment, FIG. 2 is a perspective view showing a corrugated tube 2 of the wire harness 1, and FIG. 3 is a front view showing the corrugated tube 2. FIG. 4 is a perspective view showing a manufacturing apparatus 100 for manufacturing the corrugated tube 2, and FIG. 5 is a bottom view showing how the corrugated tube is manufactured by the manufacturing apparatus 100.

本実施形態のワイヤハーネス１は、例えば車両に配索されて電装部品に電力を供給したり信号を送信したりするためのものであって、図１に示すように、コルゲートチューブ２と電線３とを備える。   The wire harness 1 according to the present embodiment is, for example, arranged in a vehicle to supply power to an electrical component or transmit a signal, and as shown in FIG. With.

コルゲートチューブ２は、例えば絶縁性の合成樹脂によって構成され、図２にも示すように、円筒状に形成されるとともに、その外周面に凹凸が軸方向に交互に並んで蛇腹状に形成され、容易に屈曲可能となっている。また、コルゲートチューブ２には、軸方向に沿って延びる１本のスリット部２１が形成されている。   The corrugated tube 2 is made of, for example, an insulating synthetic resin, and as shown in FIG. 2, the corrugated tube 2 is formed in a cylindrical shape, and the outer peripheral surface thereof is formed in a bellows shape alternately in the axial direction. It can be bent easily. The corrugated tube 2 is formed with one slit portion 21 extending along the axial direction.

コルゲートチューブ２の一端２Ａには、樋状の突出部２２が形成されている。突出部２２は、軸方向に沿って延びる一対の縁部２２１、２２２と、円弧状の軸方向端部２２３と、を有する。   At one end 2A of the corrugated tube 2, a bowl-shaped protrusion 22 is formed. The protruding portion 22 has a pair of edge portions 221 and 222 extending along the axial direction, and an arc-shaped axial end portion 223.

一方の縁部２２１は、スリット部２１に連続して形成され、他方の縁部２２２は、縁部２２１と径方向に対向する位置に形成されている。軸方向端部２２３は、図３に示すように、中心角θが略１８０°の円弧状に形成されている。即ち、突出部２２は、半円状の断面を有する。   One edge portion 221 is formed continuously with the slit portion 21, and the other edge portion 222 is formed at a position facing the edge portion 221 in the radial direction. As shown in FIG. 3, the axial end 223 is formed in an arc shape having a central angle θ of approximately 180 °. That is, the protrusion 22 has a semicircular cross section.

本実施形態では、突出部２２は、コルゲートチューブ２の外周面の凹凸２つずつに相当する長さを有しているものとするが、突出部の長さは、後述するようにテープ巻きした際に適宜な固定力が得られるような長さであればよく、例えばコルゲートチューブの内径や電線の内径、テープの粘着力等の各種の条件に応じて設定されればよい。   In the present embodiment, the projecting portion 22 has a length corresponding to each of the two irregularities on the outer peripheral surface of the corrugated tube 2, but the length of the projecting portion is taped as will be described later. The length may be set so as to obtain an appropriate fixing force, and may be set according to various conditions such as the inner diameter of the corrugated tube, the inner diameter of the electric wire, and the adhesive strength of the tape.

電線３は、コルゲートチューブ２に挿通され、例えば車両に搭載されたバッテリやＥＣＵと電装部品とを接続する。電線３のうちコルゲートチューブ２の突出部２２に位置づけられた部分は、突出部２２によって周方向の一部が覆われるとともに他の部分が露出する。この露出した部分が露出部３１となる。尚、電線３は、複数本の導体によって構成されたものであってもよいし、１本の導体によって構成されていてもよい。   The electric wire 3 is inserted into the corrugated tube 2 and connects, for example, a battery or ECU mounted on the vehicle and an electrical component. A portion of the electric wire 3 positioned at the protruding portion 22 of the corrugated tube 2 is covered with the protruding portion 22 in the circumferential direction and the other portion is exposed. This exposed portion becomes the exposed portion 31. The electric wire 3 may be constituted by a plurality of conductors or may be constituted by a single conductor.

以上のようなワイヤハーネス１において、図１に示すように、コルゲートチューブ２の一端２Ａと電線３の露出部３１とにテープ４が巻き付けられることで、コルゲートチューブのテープ巻き構造１０が構成される。即ち、突出部２２と露出部３１とをまとめてテープ巻きする。これにより、軸方向において重複する領域に形成された突出部２２と露出部３１との両者にテープが貼り付けられる。また、テープ巻き時に、巻き付ける力によって突出部２２が電線３に合わせて変形してもよく、変形した場合には、突出部２２と電線３との隙間が小さくなる。   In the wire harness 1 as described above, as shown in FIG. 1, the tape 4 is wound around the one end 2 </ b> A of the corrugated tube 2 and the exposed portion 31 of the electric wire 3, thereby configuring the tape winding structure 10 of the corrugated tube. . That is, the protruding portion 22 and the exposed portion 31 are collectively wound with tape. Thereby, a tape is affixed on both the protrusion part 22 and the exposed part 31 which were formed in the area | region which overlaps in an axial direction. Moreover, the protrusion part 22 may deform | transform according to the electric wire 3 with the force to wind at the time of tape winding, and when it deform | transforms, the clearance gap between the protrusion part 22 and the electric wire 3 will become small.

尚、突出部２２はテープ巻き時に変形しなくてもよい。また、テープ巻きは先端側または軸方向中央部側のいずれから開始してもよく、適宜に重ねつつ螺旋状にテープ４を巻き付ければよい。このとき、テープ巻きされる範囲は、例えば、少なくとも突出部２２の基端から先端までを含むとともに、その前後も適宜な長さだけ含む範囲であればよい。   In addition, the protrusion part 22 does not need to deform | transform at the time of tape winding. Tape winding may be started from either the front end side or the axial center side, and the tape 4 may be wound spirally while being appropriately stacked. At this time, the tape-wrapped range may be, for example, a range that includes at least the proximal end to the distal end of the protruding portion 22 and includes an appropriate length before and after that.

このようなテープ巻き作業は、手作業により実施されてもよいし、適宜なテープ巻き装置によって自動化されてもよい。従来のコルゲートチューブのようにテープ４をスリット部２１に通す必要がないため、作業が単純であり容易に自動化することができる。   Such a tape winding operation may be performed manually or may be automated by an appropriate tape winding device. Since it is not necessary to pass the tape 4 through the slit portion 21 unlike a conventional corrugated tube, the operation is simple and can be easily automated.

次に、上記のようなコルゲートチューブ２を製造する製造装置１００について説明する。   Next, the manufacturing apparatus 100 which manufactures the above corrugated tubes 2 is demonstrated.

コルゲートチューブの製造装置１００は、図４に示すように、長尺状かつ蛇腹状の筒状部材２００を適宜な長さに切断することによって上記のようなコルゲートチューブ２を製造するものであって、筒状部材２００を移動させる移動手段１１０と、筒状部材２００を案内する図示しない案内手段と、筒状部材２００を切断する切断手段１２０と、を備える。コルゲートチューブの製造装置１００は、筒状部材２００の軸方向を水平面内の一方向に向けつつ、筒状部材２００を軸方向に沿って移動させる。この移動方向をＸ方向とし、水平面内においてＸ方向に略直交する方向をＹ方向とし、上下方向をＺ方向とする。   As shown in FIG. 4, the corrugated tube manufacturing apparatus 100 manufactures the corrugated tube 2 as described above by cutting a long and bellows-shaped cylindrical member 200 into an appropriate length. , A moving means 110 for moving the cylindrical member 200, a guide means (not shown) for guiding the cylindrical member 200, and a cutting means 120 for cutting the cylindrical member 200. The corrugated tube manufacturing apparatus 100 moves the cylindrical member 200 along the axial direction while directing the axial direction of the cylindrical member 200 in one direction in the horizontal plane. This moving direction is defined as the X direction, the direction substantially orthogonal to the X direction in the horizontal plane is defined as the Y direction, and the vertical direction is defined as the Z direction.

移動手段１１０は、筒状部材２００の外周面の凹凸に噛み合う一対のギア１１１によって構成されている。一対のギア１１１は、Ｙ方向から筒状部材２００を挟み込み、Ｚ方向に沿った回転軸を中心に回転することで筒状部材２００をＸ方向に移動させる。   The moving means 110 is constituted by a pair of gears 111 that mesh with the irregularities on the outer peripheral surface of the cylindrical member 200. The pair of gears 111 sandwich the cylindrical member 200 from the Y direction, and move the cylindrical member 200 in the X direction by rotating around the rotation axis along the Z direction.

案内手段は、例えば板状又は棒状に形成され、筒状部材２００のスリット部に挿入されることにより、スリット部の延在方向（即ちＸ方向）に筒状部材２００を案内する。尚、本実施形態では、筒状部材２００のスリット部は下方側に向けられている。   The guide means is formed in a plate shape or a rod shape, for example, and is inserted into the slit portion of the cylindrical member 200 to guide the cylindrical member 200 in the extending direction of the slit portion (that is, the X direction). In the present embodiment, the slit portion of the cylindrical member 200 is directed downward.

切断手段１２０は、Ｘ方向に並んだ一対の第１切断刃１２１、１２２と、一対の第１切断刃１２１、１２２の間に設けられた第２切断刃１２３と、切断刃１２１〜１２３を保持する保持部１２４と、保持部１２４をＺ方向に沿って昇降させる昇降手段と、を有する。   The cutting means 120 holds a pair of first cutting blades 121 and 122 arranged in the X direction, a second cutting blade 123 provided between the pair of first cutting blades 121 and 122, and the cutting blades 121 to 123. And holding means 124 for raising and lowering the holding part 124 along the Z direction.

第１切断刃１２１、１２２は、ＹＺ平面に沿った板状に形成され、先端が下方側を向くように保持される。一対の第１切断刃１２１、１２２は、Ｘ方向に所定の間隔をあけて配置され、この間隔が突出部２２の突出寸法に略等しくなる。また、一対の第１切断刃１２１、１２２は、Ｘ方向から見て互いに重ならないように、Ｙ方向にずれて配置されている。具体的には、一方の第１切断刃１２１が筒状部材２００のＹ方向における半分（図４における手前側半分）を切断し、他方の第１切断刃１２２が残り半分（図４における奥側半分）を切断するように配置されている。   The first cutting blades 121 and 122 are formed in a plate shape along the YZ plane, and are held so that the tips are directed downward. The pair of first cutting blades 121 and 122 are arranged at a predetermined interval in the X direction, and this interval is substantially equal to the protruding dimension of the protruding portion 22. Further, the pair of first cutting blades 121 and 122 are arranged so as to be shifted in the Y direction so as not to overlap each other when viewed from the X direction. Specifically, one first cutting blade 121 cuts half of the tubular member 200 in the Y direction (front half in FIG. 4), and the other first cutting blade 122 has the remaining half (back side in FIG. 4). Is arranged to cut half).

第２切断刃１２３は、ＺＸ平面に沿った板状に形成され、先端が下方側を向くように保持される。第２切断刃１２３は、筒状部材２００のＹ方向中央部を切断するように、一方の第１切断刃１２１のＹ方向端部から他方の第１切断刃１２２のＹ方向端部に亘って設けられている。また、第２切断刃１２３の先端は、第１切断刃１２１、１２２の先端よりも所定の寸法（例えば筒状部材２００の直径）だけ上方側に配置されている。これにより、昇降手段によって保持部１２４を下降させ、第１切断刃１２１、１２２によってそれぞれ筒状部材２００のＹ方向半分を切断する際に、第２切断刃１２３によって筒状部材２００の上方側のみが切断されるようになっている。   The second cutting blade 123 is formed in a plate shape along the ZX plane and is held so that the tip is directed downward. The second cutting blade 123 extends from the Y-direction end of one first cutting blade 121 to the Y-direction end of the other first cutting blade 122 so as to cut the Y-direction center of the cylindrical member 200. Is provided. The tip of the second cutting blade 123 is disposed above the tips of the first cutting blades 121 and 122 by a predetermined dimension (for example, the diameter of the cylindrical member 200). Thus, when the holding unit 124 is lowered by the lifting and lowering means and the first cutting blades 121 and 122 respectively cut the half of the cylindrical member 200 in the Y direction, only the upper side of the cylindrical member 200 by the second cutting blade 123. Is to be disconnected.

以上のようなコルゲートチューブの製造装置１００によって筒状部材２００を切断してコルゲートチューブを製造する方法について説明する。尚、筒状部材２００は、製造するコルゲートチューブの２本分の長さを有しているものとする。   A method of manufacturing the corrugated tube by cutting the tubular member 200 using the corrugated tube manufacturing apparatus 100 as described above will be described. In addition, the cylindrical member 200 shall have the length for two corrugated tubes to manufacture.

まず、案内手段をスリット部に挿通しつつ筒状部材２００をコルゲートチューブの製造装置１００にセットする。次に、移動手段１１０によって筒状部材２００をＸ方向に移動させる。この移動距離は、製造したいコルゲートチューブの長さに応じて適宜に設定されればよい。次に、切断手段１２０の昇降手段によって保持部１２４を下降させ、切断刃１２１〜１２３によって図５に示すように筒状部材２００を切断する。図５は、筒状部材２００を下方視した図であり、第１切断刃１２１による切断線をＬ１とし、第１切断刃１２２による切断線をＬ２とし、第２切断刃１２３による切断線をＬ３とする。尚、このような切断によって形成された角部を面取りしてアール部を形成してもよい。   First, the cylindrical member 200 is set in the corrugated tube manufacturing apparatus 100 while the guide means is inserted through the slit portion. Next, the cylindrical member 200 is moved in the X direction by the moving means 110. This moving distance may be appropriately set according to the length of the corrugated tube to be manufactured. Next, the holding part 124 is lowered by the lifting means of the cutting means 120, and the cylindrical member 200 is cut by the cutting blades 121 to 123 as shown in FIG. FIG. 5 is a view of the cylindrical member 200 as viewed from below, where the cutting line by the first cutting blade 121 is L1, the cutting line by the first cutting blade 122 is L2, and the cutting line by the second cutting blade 123 is L3. And Note that the rounded portion may be formed by chamfering the corner portion formed by such cutting.

このように筒状部材２００を切断することにより、それぞれ突出部２２を有する２本のコルゲートチューブ２が形成される。このとき、第１切断刃１２１、１２２によって軸方向端部２２３が形成され、第２切断刃１２３によって他方の縁部２２２が形成される。   By cutting the cylindrical member 200 in this manner, two corrugated tubes 2 each having a protruding portion 22 are formed. At this time, the axial end 223 is formed by the first cutting blades 121 and 122, and the other edge 222 is formed by the second cutting blade 123.

このような本実施形態によれば、以下のような効果がある。即ち、コルゲートチューブ２が樋状の突出部２２を有することで、突出部２２と、電線３の露出部３１と、をまとめてテープ巻きし、軸方向において重複する領域に形成された突出部２２と露出部３１との両者にテープが貼り付けられ、固定力を向上させることができる。また、テープ巻き時に突出部２２が電線３に合わせて変形すれば、突出部２２と電線３との隙間が小さくなり、固定力をさらに向上させることができる。このとき、コルゲートチューブ２を電線３に合わせて変形させるための特別な工程は必要なく、単にテープ４を巻き付けるだけでよいため、テープ巻き作業を効率化することができる。   According to this embodiment, there are the following effects. That is, since the corrugated tube 2 has the hook-shaped protrusion 22, the protrusion 22 and the exposed portion 31 of the electric wire 3 are taped together, and the protrusion 22 formed in a region overlapping in the axial direction. A tape is affixed to both the exposed portion 31 and the exposed portion 31, and the fixing force can be improved. Moreover, if the protrusion part 22 deform | transforms according to the electric wire 3 at the time of tape winding, the clearance gap between the protrusion part 22 and the electric wire 3 will become small, and a fixing force can be improved further. At this time, there is no need for a special process for deforming the corrugated tube 2 in accordance with the electric wire 3, and it is only necessary to wind the tape 4, so that the tape winding operation can be made efficient.

また、突出部２２が半円状の断面を有することで、切断刃１２１〜１２３によって筒状部材２００を切断して２本のコルゲートチューブ２を得る際に、両方のコルゲートチューブ２に突出部２２が形成される。即ち、１回の切断で同様の突出部２２を２本のコルゲートチューブ２に形成することができる。   Moreover, when the protrusion part 22 has a semicircular cross section, when the cylindrical member 200 is cut | disconnected by the cutting blades 121-123 and the two corrugated tubes 2 are obtained, the protrusion part 22 is provided to both corrugated tubes 2. Is formed. That is, the same protrusion 22 can be formed in the two corrugated tubes 2 by one cutting.

また、切断刃１２１〜１２３によって２本のコルゲートチューブ２に突出部２２を形成し、２つの突出部２２の中心角の合計が略３６０°であることで、切りカスがほとんど発生しない。従って、原材料の無駄を削減して低コスト化するとともに、切りカスを除去するための工程を省略したり簡略化したりすることができる。   Further, the protruding portions 22 are formed on the two corrugated tubes 2 by the cutting blades 121 to 123, and the sum of the central angles of the two protruding portions 22 is approximately 360 °, so that almost no cutting residue is generated. Therefore, waste of raw materials can be reduced and the cost can be reduced, and a process for removing cut waste can be omitted or simplified.

また、樋状の突出部２２の一方の縁部２２１がスリット部２１と連続していることで、この縁部２２１を形成するために筒状部材２００を切断する必要がなく、切断手段１２０の切断刃の数を減らして製造装置１００を簡素化することができる。   Moreover, since one edge part 221 of the bowl-shaped protrusion part 22 is following the slit part 21, it is not necessary to cut the cylindrical member 200 in order to form this edge part 221. The manufacturing apparatus 100 can be simplified by reducing the number of cutting blades.

なお、本発明は、前記実施形態に限定されるものではなく、本発明の目的が達成できる他の構成等を含み、以下に示すような変形等も本発明に含まれる。   In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.

例えば、前記実施形態では、突出部２２が半円状の断面を有する（中心角θが１８０°である）ものとしたが、図６に示すように中心角θが１８０°未満の突出部２２Ｂとしてもよいし、図７に示すように中心角θが１８０°よりも大きい突出部２２Ｃとしてもよい。このように中心角θを１８０°以外の値とする場合であっても、２本のコルゲートチューブ２に突出部を形成する際に、２つの突出部の中心角の合計を略３６０°とすれば、前記実施形態と同様に切りカスがほとんど発生しない。   For example, in the above-described embodiment, the protrusion 22 has a semicircular cross section (the central angle θ is 180 °). However, as shown in FIG. 6, the protrusion 22B has a central angle θ of less than 180 °. Alternatively, as illustrated in FIG. 7, the protrusion 22 </ b> C having a central angle θ larger than 180 ° may be used. Thus, even when the central angle θ is set to a value other than 180 °, when the protrusions are formed on the two corrugated tubes 2, the sum of the central angles of the two protrusions is approximately 360 °. For example, almost no cutting residue is generated as in the above embodiment.

また、前記実施形態では、筒状部材２００を１回切断して２本のコルゲートチューブ２を得る、即ち、コルゲートチューブ２の一端２Ａにのみ突出部２２が形成されるものとしたが、コルゲートチューブ２の両端に突出部を形成してもよい。このとき、両端の突出部の形成位置の関係は任意であり、例えば樋状の２つの突出部が同じ向きに凸に形成されていてもよいし、反対向きに凸に形成されていてもよい。   Moreover, in the said embodiment, although the cylindrical member 200 was cut | disconnected once and the two corrugated tubes 2 were obtained, ie, the protrusion part 22 shall be formed only in the one end 2A of the corrugated tube 2, a corrugated tube Projections may be formed at both ends of the two. At this time, the relationship of the formation positions of the protrusions at both ends is arbitrary. For example, the two hook-shaped protrusions may be formed in the same direction or may be formed in the opposite direction. .

また、図８に示すように、一端２Ａ側の突出部２２と他端２Ｂ側の突出部２３とを軸方向から見て重ならない位置に形成すれば、前記実施形態のようなコルゲートチューブの製造装置１００によって容易に突出部を形成しつつ切断することができる。具体的には、１回目の切断によって第１のコルゲートチューブ２の一端２Ａに突出部２２を形成し、２回目の切断によって第１のコルゲートチューブ２の他端２Ｂに突出部２３を形成する。２回目の切断によって筒状部材に突出部が形成され、この突出部が第２のコルゲートチューブ２’の一端２Ａの突出部２２となる。３回目の切断によって第２のコルゲートチューブ２’の他端２Ｂに突出部２３が形成される。このように同一の切断作業を複数回繰り返すことにより、両端に同様の突出部２２、２３を有する複数本のコルゲートチューブを容易に製造することができる。   Moreover, as shown in FIG. 8, if the protrusion part 22 by the side of one end 2A and the protrusion part 23 by the side of the other end 2B are formed in the position which does not overlap seeing from an axial direction, manufacture of a corrugated tube like the said embodiment will be carried out. The apparatus 100 can be easily cut while forming the protrusion. Specifically, the protrusion 22 is formed at one end 2A of the first corrugated tube 2 by the first cutting, and the protrusion 23 is formed at the other end 2B of the first corrugated tube 2 by the second cutting. A protrusion is formed in the cylindrical member by the second cutting, and this protrusion becomes the protrusion 22 of the one end 2A of the second corrugated tube 2 '. A protrusion 23 is formed at the other end 2B of the second corrugated tube 2 'by the third cutting. In this way, by repeating the same cutting operation a plurality of times, a plurality of corrugated tubes having the same protrusions 22 and 23 at both ends can be easily manufactured.

また、前記実施形態では、コルゲートチューブ２が円筒状であるものとしたが、コルゲートチューブは、楕円筒状であってもよいし、角筒状であってもよい。   Moreover, in the said embodiment, although the corrugated tube 2 shall be cylindrical shape, an elliptical cylinder shape may be sufficient as a corrugated tube, and a rectangular tube shape may be sufficient as it.

また、前記実施形態では、突出部２２の一方の縁部２２１がコルゲートチューブ２のスリット部２１に連続しているものとしたが、スリット部とは異なる位置に一対の縁部を形成してもよい。また、コルゲートチューブはスリット部を有していなくてもよい。   Moreover, in the said embodiment, although the one edge part 221 of the protrusion part 22 shall be continued to the slit part 21 of the corrugated tube 2, even if it forms a pair of edge part in the position different from a slit part. Good. Moreover, the corrugated tube may not have a slit part.
