　＜第１実施形態＞
　第１実施形態に係る配線モジュールについて説明する。 <First Embodiment>
The wiring module according to the first embodiment will be described.
　　＜配線モジュール＞
　図１は配線モジュール２０を示す概略図であり、図２は同配線モジュール２０の部分拡大概略図である。 <Wiring module>
FIG. 1 is a schematic view showing the wiring module 20, and FIG. 2 is a partially enlarged schematic view of the wiring module 20.
　この配線モジュール２０は、少なくとも１本の線状導体として複数の被覆電線２２と、前記複数の被覆電線２２の一端部に取付けられた端部部品としてのコネクタ３０と、コルゲートチューブ１０とを備える。 The wiring module 20 includes a plurality of covered electric wires 22 as at least one linear conductor, a connector 30 as an end part attached to one end of the plurality of covered electric wires 22, and the corrugated tube 10.
　複数の被覆電線２２は、分岐しつつ粘着テープ等の結束部材を用いて結束されている。これにより、ワイヤーハーネス２３が構成されている。ワイヤーハーネス２３の各分岐部分の先端部にはコネクタ３０が取付けられている。本ワイヤーハーネス２３が車両に組付けられた状態で、各コネクタ３０が車両に搭載された各種電気部品に接続される。これにより、車両に搭載された各種電気部品が本ワイヤーハーネス２３を通じて電気的に接続される。 The plurality of covered electric wires 22 are bundled using a bundling member such as an adhesive tape while branching. Thereby, the wire harness 23 is comprised. A connector 30 is attached to the tip of each branch portion of the wire harness 23. In a state where the wire harness 23 is assembled to the vehicle, each connector 30 is connected to various electric components mounted on the vehicle. Thereby, various electrical components mounted on the vehicle are electrically connected through the wire harness 23.
　上記分岐部分の少なくとも１つ（ここでは１つ）の分岐部分２３ａに、コルゲートチューブ１０が装着されている。すなわち、分岐部分２３ａに含まれる被覆電線２２の端部の端子は、コネクタ３０のキャビティに挿入されている。これにより、分岐部分２３ａの先端部にコネクタ３０が取付けられている。コネクタ３０は、通常、分岐部分２３ａよりも大きい。 The corrugated tube 10 is attached to at least one branch portion 23a (here, one) of the branch portions. That is, the terminal at the end of the covered electric wire 22 included in the branch portion 23 a is inserted into the cavity of the connector 30. Thereby, the connector 30 is attached to the front-end | tip part of the branch part 23a. The connector 30 is usually larger than the branch part 23a.
　コルゲートチューブ１０は、筒形状に形成され、加熱によりコルゲートチューブ形状を呈するように熱収縮可能な部分を含む熱収縮コルゲートチューブ１０Ｂにより構成されている。かかる熱収縮コルゲートチューブ１０Ｂ及びその製造方法例については後で説明する。 The corrugated tube 10 is formed of a heat-shrinkable corrugated tube 10B including a portion that is formed in a cylindrical shape and can be heat-shrinked so as to exhibit a corrugated tube shape by heating. Such a heat-shrinkable corrugated tube 10B and an example of its manufacturing method will be described later.
　このコルゲートチューブ１０は、上記被覆電線２２のうちの少なくともコネクタ３０側の部分を覆った状態でコルゲートチューブ形状を呈するように熱収縮した第１部分１０ａと、コネクタ３０のうち少なくとも被覆電線２２側の部分を覆った状態で熱収縮した第２部分１０ｂとを含む。 The corrugated tube 10 includes a first portion 10a that is thermally shrunk so as to exhibit a corrugated tube shape in a state of covering at least a portion of the covered electric wire 22 on the connector 30 side, and at least a portion of the connector 30 on the covered electric wire 22 side. And a second portion 10b that is thermally contracted in a state of covering the portion.
　すなわち、１つのコルゲートチューブ１０が、被覆電線２２のうちコネクタ３０側の部分からコネクタ３０のうち被覆電線２２の部分に亘って全体を覆っている。 That is, one corrugated tube 10 covers the entire covered wire 22 from the portion on the connector 30 side to the covered wire 22 portion of the connector 30.
　そして、このコルゲートチューブ１０のうち被覆電線２２を覆う第１部分１０ａがコルゲートチューブ形状を呈するように熱収縮している。ここでは、第１部分１０ａは、その延在方向に沿って太環状部１２と細環状部１４とが交互に連続して設けられた筒状をなすコルゲートチューブ形状に形成されている。このコルゲートチューブ形状については、後でさらに説明する。 And the 1st part 10a which covers the covered electric wire 22 among this corrugated tube 10 is thermally contracted so that a corrugated tube shape may be exhibited. Here, the 1st part 10a is formed in the corrugated tube shape which makes | forms the cylindrical shape in which the thick annular part 12 and the narrow annular part 14 were provided continuously by turns along the extension direction. The corrugated tube shape will be further described later.
　また、コルゲートチューブ１０のうちコネクタ３０を覆う第２部分１０ｂは、コネクタ３０のうちの被覆電線２２の部分の外周全体を覆うように熱収縮している。好ましくは、第２部分１０ｂは、その内周部とコネクタ３０の外周部との隙間をなるべく少なくするように、当該コネクタ３０の外周形状に応じた形状に熱収縮している。ここでは、コネクタ３０は、直方体状に形成されているため、第２部分１０ｂは、コネクタ３０の外周形状に倣って方形筒状をなすように熱収縮している。 Further, the second portion 10 b covering the connector 30 in the corrugated tube 10 is thermally contracted so as to cover the entire outer periphery of the covered wire 22 portion in the connector 30. Preferably, the second portion 10b is thermally contracted into a shape corresponding to the outer peripheral shape of the connector 30 so as to reduce the gap between the inner peripheral portion and the outer peripheral portion of the connector 30 as much as possible. Here, since the connector 30 is formed in a rectangular parallelepiped shape, the second portion 10 b is thermally contracted so as to form a rectangular tube shape following the outer peripheral shape of the connector 30.
　コルゲートチューブ１０の内周部、好ましくは、第２部分１０ｂとコネクタ３０との間にホットメルト等の接着剤が介在している。これにより、第２部分１０ｂとコネクタ３０との隙間を当該接着剤が埋めることができる。 An adhesive such as hot melt is interposed between the inner peripheral portion of the corrugated tube 10, preferably between the second portion 10b and the connector 30. Thereby, the said adhesive agent can fill the clearance gap between the 2nd part 10b and the connector 30. FIG.
　なお、第２部分１０ｂには、コネクタ３０を覆った状態で、コルゲートチューブ形状に応じた段差が形成されていてもよいし、そのような段差がない筒形状に形成されていてもよい。第２部分１０ｂが、コルゲートチューブ形状を呈するか呈さないかは、熱収縮コルゲートチューブ１０Ｂの元の大きさとコネクタ３０との大きさとの差異による。コネクタ３０が比較的大きく、熱収縮コルゲートチューブ１０Ｂの収縮度合が小さい場合には、第２部分１０ｂには、コルゲートチューブ形状に応じた段差が生じ難い。また、コネクタ３０が比較的小さく、熱収縮コルゲートチューブ１０Ｂの収縮度合が大きい場合には、第２部分１０ｂには、コルゲートチューブ形状に応じた段差が生じ易い。また、熱収縮コルゲートチューブ１０Ｂのうちコネクタ３０を覆う部分が、コルゲートチューブ形状に熱収縮せず、段差がない筒形状に熱収縮する構成とされていてもよい。 The second portion 10b may be formed with a step corresponding to the corrugated tube shape with the connector 30 covered, or may be formed in a cylindrical shape without such a step. Whether or not the second portion 10b has a corrugated tube shape depends on the difference between the original size of the heat-shrinkable corrugated tube 10B and the size of the connector 30. When the connector 30 is relatively large and the degree of shrinkage of the heat-shrinkable corrugated tube 10B is small, a step corresponding to the shape of the corrugated tube is unlikely to occur in the second portion 10b. Further, when the connector 30 is relatively small and the degree of contraction of the heat-shrinkable corrugated tube 10B is large, a step corresponding to the shape of the corrugated tube is likely to occur in the second portion 10b. Moreover, the part which covers the connector 30 among heat-shrink corrugated tube 10B may be set as the structure which does not heat-shrink to a corrugated tube shape, and heat-shrinks to the cylinder shape without a level | step difference.
　なお、コルゲートチューブ１０のうち上記第１部分１０ａと第２部分１０ｂとの間には、第１部分１０ａから第２部分１０ｂに向けて徐々に拡径する部分が形成されている。この部分は、コルゲートチューブ形状を呈するが、第１部分１０ａから第２部分１０ｂに向けて徐々にその段差が小さくなる。また、この部分は、第１部分１０ａから第２部分１０ｂに向けて、徐々に第１部分１０ａの形状（ここでは円形状）から第２部分１０ｂの形状（ここでは方形状）に近づくように変形する形状とされている。 In the corrugated tube 10, a portion that gradually increases in diameter from the first portion 10a toward the second portion 10b is formed between the first portion 10a and the second portion 10b. This portion has a corrugated tube shape, but the step gradually decreases from the first portion 10a toward the second portion 10b. Also, this portion gradually approaches the shape of the second portion 10b (here square) from the shape of the first portion 10a (here circular) toward the second portion 10b from the first portion 10a. The shape is deformed.
　　＜熱収縮コルゲートチューブ＞
　上記熱収縮コルゲートチューブ１０Ｂについて説明する。 <Heat-shrink corrugated tube>
The heat shrink corrugated tube 10B will be described.
　図３は熱収縮前の熱収縮コルゲートチューブ１０Ｂを示す斜視図であり、図４は熱収縮後のコルゲートチューブ１０を示す斜視図である。 FIG. 3 is a perspective view showing the heat-shrinkable corrugated tube 10B before heat shrinking, and FIG. 4 is a perspective view showing the corrugated tube 10 after heat shrinking.
　熱収縮コルゲートチューブ１０Ｂは、筒形状をなしている。熱収縮コルゲートチューブ１０Ｂには、その延在方向全体に沿った切れ目は形成されていない。ここでは、熱収縮コルゲートチューブ１０Ｂは、円筒状をなしているが、三角形筒状、四角形状等の多角形筒状をなしていてもよいし、楕円筒状をなしていてもよい。また、熱収縮コルゲートチューブ１０Ｂは、その延在方向において同じ大きさの断面形状が連続する筒形状に形成されている。もっとも、熱収縮コルゲートチューブ１０Ｂは、熱収縮後のコルゲートチューブ１０よりも段差が小さい程度で、熱収縮後のコルゲートチューブ１０の太環状部１２及び細環状部１４に応じた凹凸が形成されていてもよい。 The heat-shrink corrugated tube 10B has a cylindrical shape. The heat shrink corrugated tube 10B is not formed with a cut along the entire extending direction. Here, the heat-shrinkable corrugated tube 10B has a cylindrical shape, but may have a polygonal cylindrical shape such as a triangular cylindrical shape or a rectangular shape, or may have an elliptical cylindrical shape. The heat-shrinkable corrugated tube 10B is formed in a cylindrical shape in which cross-sectional shapes of the same size are continuous in the extending direction. Of course, the heat-shrinkable corrugated tube 10B has a level difference smaller than that of the corrugated tube 10 after heat shrinkage, and irregularities corresponding to the thick annular portion 12 and the thin annular portion 14 of the corrugated tube 10 after heat shrinkage are formed. Also good.
　また、上記したように、熱収縮コルゲートチューブのうちコネクタを覆う部分が、コルゲートチューブ形状を呈さない形状、すなわち、その延在方向に沿って同一の大きさ（同一径）部分が連続する筒形状に形成されていてもよい。 In addition, as described above, the portion of the heat-shrinkable corrugated tube that covers the connector has a shape that does not exhibit a corrugated tube shape, that is, a cylindrical shape in which the same size (same diameter) portion continues along the extending direction. It may be formed.
　熱収縮後のコルゲートチューブ１０は、コルゲートチューブ形状を呈している。このコルゲートチューブ１０にも、その延在方向に沿った切れ目であって当該延在方向全体に亘って存在するものは形成されていない。コルゲートチューブ１０は、その延在方向に沿って太環状部１２と細環状部１４とが交互に連続して設けられた筒状に形成されている。ここでは、太環状部１２と細環状部１４とは、それぞれ円形環状（チューブ１０の軸方向に対して直交する断面視が円形状）に形成されている。もっとも、コルゲートチューブ１０の断面形状は、円形状に限られず、楕円形、多角形状等でもよい。そして、コルゲートチューブ１０の内側には、被覆電線等を配設可能な空間が存在している。すなわち、太環状部１２の内部空間と、細環状部１４の内部空間とが、コルゲートチューブ１０の延在方向に連続している。 The corrugated tube 10 after heat shrinkage has a corrugated tube shape. The corrugated tube 10 is also not formed with a cut along the extending direction and existing throughout the extending direction. The corrugated tube 10 is formed in a cylindrical shape in which large annular portions 12 and narrow annular portions 14 are provided alternately and continuously along the extending direction. Here, the thick annular portion 12 and the narrow annular portion 14 are each formed in a circular annular shape (a circular sectional view perpendicular to the axial direction of the tube 10). However, the cross-sectional shape of the corrugated tube 10 is not limited to a circular shape, and may be an elliptical shape, a polygonal shape, or the like. And inside the corrugated tube 10, the space which can arrange | position a covered electric wire etc. exists. That is, the internal space of the thick annular portion 12 and the internal space of the narrow annular portion 14 are continuous in the extending direction of the corrugated tube 10.
　上記太環状部１２と細環状部１４との間には、コルゲートチューブ１０の外周側から内周側に向う円盤状の介在部１３が存在している。介在部１３は、太環状部１２及び細環状部１４に対しても角をなして繋がっている。従って、コルゲートチューブ１０をその軸方向沿った断面で観察すると、矩形波が連続する形状を示す。もっとも、コルゲートチューブの軸方向に沿った断面は、サイン波又は三角波等が連続する形状であってもよい。コルゲートチューブ形状とは、太い環状部分と細い環状部分とがその軸方向に沿って交互に連続する形状全てを含む。 Between the thick annular portion 12 and the narrow annular portion 14, there is a disc-shaped interposition portion 13 that extends from the outer peripheral side to the inner peripheral side of the corrugated tube 10. The interposition part 13 is also connected to the thick annular part 12 and the narrow annular part 14 at an angle. Therefore, when the corrugated tube 10 is observed in a cross section along the axial direction, a shape in which rectangular waves are continuous is shown. But the cross section along the axial direction of a corrugated tube may be a shape where a sine wave or a triangular wave continues. The corrugated tube shape includes all shapes in which thick annular portions and thin annular portions are alternately continued along the axial direction.
　上記細環状部１４の内径寸法は、熱収縮前の熱収縮コルゲートチューブ１０Ｂの内径寸法よりも小さい。好ましくは、太環状部１２と細環状部１４との双方の内径寸法は、熱収縮前の熱収縮コルゲートチューブ１０Ｂの内径寸法よりも小さい。 The inner diameter of the narrow annular portion 14 is smaller than the inner diameter of the heat shrink corrugated tube 10B before heat shrink. Preferably, the inner diameter dimensions of both the thick annular portion 12 and the narrow annular portion 14 are smaller than the inner diameter dimension of the heat-shrinkable corrugated tube 10B before heat shrinking.
　本コルゲートチューブ１０は、太環状部１２と介在部１３との間、細環状部１４と介在部１３との間、或は、介在部１３が弾性変形することで、容易に曲ることができる。 The corrugated tube 10 can be easily bent between the thick annular portion 12 and the interposed portion 13, between the narrow annular portion 14 and the interposed portion 13, or when the interposed portion 13 is elastically deformed. .
　上記熱収縮前の熱収縮コルゲートチューブ１０Ｂは、熱収縮後のコルゲートチューブ１０の形状を呈するように熱収縮することができる。すなわち、熱収縮コルゲートチューブ１０Ｂは、細くなる（ここでは、内径寸法を小さくする）と共に上記太環状部１２と細環状部１４とが交互に連続する形状となるように熱収縮することができる。ここで、熱収縮コルゲートチューブ１０Ｂが細くなる場合には、その延在方向全体が細くなる場合、及び、その延在方向の一部（例えば、細環状部１４に対応する部分）が細くなる場合を含む。 The heat-shrinkable corrugated tube 10B before heat shrinkage can be heat-shrinked so as to exhibit the shape of the corrugated tube 10 after heat-shrinking. That is, the heat-shrinkable corrugated tube 10B can be heat-shrinked so as to be thin (in this case, the inner diameter dimension is reduced) and to have a shape in which the thick annular portions 12 and the fine annular portions 14 are alternately continuous. Here, when the heat-shrinkable corrugated tube 10B becomes thin, when the whole extending direction becomes thin, and when a part of the extending direction (for example, a portion corresponding to the narrow annular portion 14) becomes thin. including.
　ここでは、熱収縮コルゲートチューブ１０Ｂは、架橋可能な重合体によって構成されており、後述するように、複数の重合体がコルゲートチューブ形状を記憶した状態で架橋した架橋構造を含み、この架橋構造がコルゲートチューブ形状を記憶した状態のまま引き伸ばされた構成とされている。架橋可能な重合体としては、ポリエチレン、エチレン－酢酸ビニル共重合体、ポリオレフィン、フッ素樹脂等を用いることができる。 Here, the heat-shrinkable corrugated tube 10B is made of a crosslinkable polymer, and includes a crosslinked structure in which a plurality of polymers memorize the corrugated tube shape as described later. It is set as the structure extended with the corrugated tube shape memorized. As the crosslinkable polymer, polyethylene, ethylene-vinyl acetate copolymer, polyolefin, fluororesin, or the like can be used.
　熱収縮コルゲートチューブ１０Ｂの内部には、ホットメルト等の接着剤が付着していることが好ましく、より好ましくは、それらが熱収縮コルゲートチューブの端部の内側のみに付着している。この接着剤は、コネクタ等に対してコルゲートチューブを接着する役割及びコネクタとコルゲートチューブとの間の隙間を塞ぐ役割を果す。 It is preferable that an adhesive such as hot melt is attached inside the heat-shrinkable corrugated tube 10B, and more preferably, they are attached only inside the end portion of the heat-shrinkable corrugated tube. This adhesive plays a role of adhering the corrugated tube to the connector and the like and closing a gap between the connector and the corrugated tube.
　このように構成された熱収縮コルゲートチューブ１０Ｂによると、熱収縮前の熱収縮コルゲートチューブ１０Ｂに対して被覆電線及びコネクタ等を容易に挿通させることができる。そして、熱収縮コルゲートチューブ１０Ｂを熱収縮させることで、熱収縮後のコルゲートチューブ１０を被覆電線及びコネクタ等に対して容易に装着できる。すなわち、その延在方向全体に沿って被覆電線等挿入用の切れ目が形成されていないコルゲートチューブ１０を、被覆電線及びコネクタ等に対して容易に装着できる。 According to the heat-shrinkable corrugated tube 10B configured in this manner, a covered electric wire, a connector, and the like can be easily inserted into the heat-shrinkable corrugated tube 10B before heat-shrinking. And the heat-shrinkable corrugated tube 10B is heat-shrinked, so that the heat-shrinkable corrugated tube 10 can be easily attached to the covered electric wire and the connector. That is, the corrugated tube 10 in which the cut for insertion of the covered electric wire or the like is not formed along the entire extending direction can be easily attached to the covered electric wire and the connector.
　また、熱収縮してコルゲートチューブ形状を呈するようになったコルゲートチューブ１０は容易に曲ることができる。このため、被覆電線等を曲げ可能な状態に保ちつつ、当該被覆電線等をコルゲートチューブ１０によって保護することができる。 Also, the corrugated tube 10 that has been heat-shrinked and has a corrugated tube shape can be easily bent. For this reason, the said covered electric wire etc. can be protected by the corrugated tube 10, keeping the covered electric wire etc. in the bendable state.
　また、コルゲートチューブに切れ目を形成し、当該切れ目を通じて被覆電線等をコルゲートチューブ内に挿入する場合には、切れ目を閉じた状態に維持するために、コルゲートチューブに粘着テープを巻回する作業等が必要となっていた。しかしながら、本熱収縮コルゲートチューブ１０Ｂによると、そのような切れ目を形成せずともよい。このため、従来のように、切れ目を閉じた状態に維持するための部材（粘着テープ等）及び作業を不要とすることができ、コルゲートチューブ１０の組付け作業の容易可及び材料費の削減等が可能となる。 In addition, when a cut is formed in the corrugated tube and a covered electric wire or the like is inserted into the corrugated tube through the cut, an operation of winding an adhesive tape around the corrugated tube in order to keep the cut closed. It was necessary. However, according to the heat-shrinkable corrugated tube 10B, such a cut need not be formed. This eliminates the need for a member (such as an adhesive tape) and work for maintaining the cut in a closed state as in the prior art, facilitates assembly work of the corrugated tube 10 and reduces material costs. Is possible.
　　＜熱収縮コルゲートチューブの製造方法＞
　上記熱収縮コルゲートチューブ１０Ｂの製造方法例について説明する。 <Method for producing heat-shrinkable corrugated tube>
An example of a method for manufacturing the heat-shrinkable corrugated tube 10B will be described.
　熱収縮コルゲートチューブ１０Ｂの製造方法は、コルゲートチューブ１０Ｃを金型成形する工程と、この工程によって金型成形されたコルゲートチューブ１０Ｃを、架橋処理する工程と、この工程によって架橋処理されたコルゲートチューブ１０Ｃを、その内部空間が大きくなるように引き伸す工程とを備える。 The manufacturing method of the heat-shrinkable corrugated tube 10B includes a step of molding the corrugated tube 10C, a step of crosslinking the corrugated tube 10C molded by this step, and a corrugated tube 10C crosslinked by this step. And a step of stretching the inner space so that the inner space becomes larger.
　図５はコルゲートチューブ１０Ｃを金型成形する工程の一例を示す説明図である。この工程では、次に説明するコルゲートチューブ金型成形装置５０を用いてコルゲートチューブ１０Ｃが製造される。 FIG. 5 is an explanatory view showing an example of a step of molding the corrugated tube 10C. In this step, the corrugated tube 10C is manufactured using a corrugated tube mold forming apparatus 50 described below.
　すなわち、コルゲートチューブ金型成形装置５０は、押出機５２と、複数対の金型６０と、金型移動機構部６８とを備える。 That is, the corrugated tube mold forming apparatus 50 includes an extruder 52, a plurality of pairs of molds 60, and a mold moving mechanism unit 68.
　押出機５２は、溶融した樹脂材料５１を、先端に設けられたダイス５３とその内側に配設されたポイントとの隙間を通じて押し出し、筒状（ここでは略円筒状）に連続供給するように構成されている。押出機５２は、閉状態の一対の金型６０内に筒状の樹脂材料５１を押し出すため、ダイス５３の先端部が、成形路Ｒ中の上流位置で閉状態の一対の金型６０間に位置するように配設されている。 The extruder 52 is configured to extrude the molten resin material 51 through a gap between a die 53 provided at the tip and a point disposed inside thereof, and continuously supply the resin material 51 in a cylindrical shape (here, substantially cylindrical shape). Has been. Since the extruder 52 pushes the cylindrical resin material 51 into the pair of molds 60 in the closed state, the tip of the die 53 is located between the pair of molds 60 in the closed state at the upstream position in the molding path R. It arrange | positions so that it may be located.
　一対の金型６０は、突き合せて配置された閉状態で、コルゲートチューブ１０の外形状に対応した形状の金型面６２をそれぞれ有している。各金型面６２は、コルゲートチューブ１０の外表面形状を、その軸方向に沿った面で２分割した形状に形成されている。この一対の金型６０は複数対用意されている。コルゲートチューブの延在方向の一部を、コルゲートチューブ形状ではない、同一径部分が連続する筒形状に形成する場合には、金型の一部を、円柱外周面形状に形成すればよい。 The pair of molds 60 each have a mold surface 62 having a shape corresponding to the outer shape of the corrugated tube 10 in a closed state in which they are arranged to face each other. Each mold surface 62 is formed in a shape obtained by dividing the outer surface shape of the corrugated tube 10 into two parts along the axial direction. A plurality of pairs of the molds 60 are prepared. When a part of the corrugated tube in the extending direction is not formed in a corrugated tube shape but is formed in a cylindrical shape with continuous portions having the same diameter, a part of the mold may be formed in a cylindrical outer peripheral surface shape.
　金型移動機構部６８は、複数対の金型６０を、それぞれ、一対の無端環状の移動路に沿って移動させるように構成されている。そして、金型移動機構部６８は、移動路のうち一対の移動路が隣合う成形路Ｒで、各移動路に沿って移動される一対の金型６０を突き合わせた閉状態にしたまま、成形路Ｒの上流側から下流側に向けて移動させる。また、金型移動機構部６８は、移動路中の成形路Ｒ以外の位置では、一対の金型６０を離れさせた開状態で各移動路を移動させる。 The mold moving mechanism 68 is configured to move a plurality of pairs of molds 60 along a pair of endless annular moving paths. The mold moving mechanism unit 68 is a molding path R adjacent to the pair of movement paths, and the molding movement mechanism 68 is in a closed state in which the pair of molds 60 moved along each movement path are in contact with each other. Move from the upstream side of the path R toward the downstream side. The mold moving mechanism 68 moves each moving path in an open state in which the pair of molds 60 are separated at positions other than the molding path R in the moving path.
　例えば、金型移動機構部６８としては、複数の金型６０を無端環状のチェーンにそれぞれ連結し、モータにより歯車を回転させて当該チェーンを送ることにより、複数対の金型６０を移動させる構成を採用することができる。 For example, the mold moving mechanism unit 68 is configured to move a plurality of pairs of molds 60 by connecting a plurality of molds 60 to an endless annular chain and rotating the gears by a motor to send the chains. Can be adopted.
　なお、上記金型６０には、押出機５２から供給される樹脂材料５１を一対の金型６０の金型面６２に密着させる構成を有している。例えば、金型６０に樹脂材料５１を吸引する吸引孔が形成され、当該吸引孔から空気を吸引することによって、樹脂材料５１を金型面に吸着する構成（バキューム成形法）、或は、筒状に押出された樹脂材料５１内に空気を送込むことによって、当該樹脂材料５１を金型面６２に密着させる構成（ブロー成形法）、又はその両方を用いた構成が採用される。 The mold 60 has a configuration in which the resin material 51 supplied from the extruder 52 is in close contact with the mold surfaces 62 of the pair of molds 60. For example, a suction hole for sucking the resin material 51 is formed in the mold 60, and the resin material 51 is adsorbed to the mold surface by sucking air from the suction hole (vacuum molding method). A configuration in which the resin material 51 is brought into close contact with the mold surface 62 by blowing air into the extruded resin material 51 (blow molding method), or a configuration using both of them is employed.
　そして、樹脂材料５１が金型６０によってコルゲートチューブ１０と同形状を呈するコルゲートチューブ１０Ｃに金型成形され、これが連続的に送出される。このコルゲートチューブ１０Ｃは、空気又は液体等を用いた冷却部６６を経て冷却された後、リール６７に巻取って収容される。 The resin material 51 is molded by a mold 60 into a corrugated tube 10C having the same shape as the corrugated tube 10, and is continuously sent out. The corrugated tube 10 </ b> C is cooled through a cooling unit 66 using air, liquid, or the like, and then wound around a reel 67 and accommodated.
　図６は、架橋処理工程を示す説明図である。 FIG. 6 is an explanatory view showing a crosslinking treatment step.
　この工程では、上記工程によって金型成形されたコルゲートチューブ１０Ｃを、架橋処理する。この工程では、次の架橋処理装置７０によって架橋処理を施す。 In this step, the corrugated tube 10C molded in the above step is subjected to a crosslinking treatment. In this step, a crosslinking process is performed by the next crosslinking apparatus 70.
　すなわち、架橋処理装置７０は、金型成形されたコルゲートチューブ１０Ｃを巻取収容したリール７２と、その下流側のリール７８と、リール７２、７８間に設けられた電子線照射装置７４とを備える。電子線照射装置７４は、その照射窓から照射される電子線を、リール７２からリール７８に向けて送られるコルゲートチューブ１０Ｃに照射可能な位置及び姿勢で配設される。 That is, the cross-linking apparatus 70 includes a reel 72 that winds and accommodates a corrugated tube 10 </ b> C that is molded, a reel 78 on the downstream side, and an electron beam irradiation device 74 provided between the reels 72 and 78. . The electron beam irradiation device 74 is disposed at a position and posture capable of irradiating the corrugated tube 10 </ b> C sent from the reel 72 toward the reel 78 with the electron beam irradiated from the irradiation window.
　そして、金型成形されたコルゲートチューブ１０Ｃがリール７２から引出されリール７８に向う途中で、電子線に曝される。これにより、コルゲートチューブ１０Ｃの重合体が架橋し、当該架橋構造がコルゲートチューブ１０Ｃの形状を記憶する。このコルゲートチューブ１０Ｃは、下流側のリール７８によって巻取られる。 Then, the corrugated tube 10C that has been molded is drawn from the reel 72 and exposed to the electron beam on the way to the reel 78. Thereby, the polymer of the corrugated tube 10C is crosslinked, and the crosslinked structure stores the shape of the corrugated tube 10C. The corrugated tube 10 </ b> C is taken up by a reel 78 on the downstream side.
　なお、ここでは、電子線によってコルゲートチューブ１０Ｃの架橋処理がなされるが、架橋処理は、その他の放射線架橋、又は、化学架橋等によってなされてもよい。 Here, although the corrugated tube 10C is subjected to crosslinking treatment with an electron beam, the crosslinking treatment may be performed by other radiation crosslinking, chemical crosslinking, or the like.
　図７は引き伸し工程を示す説明図である。この工程では、上記工程によって架橋処理されたコルゲートチューブ１０Ｃを、その内部空間が大きくなるように引き伸す。この工程は、次の拡大装置８０によって引き伸し処理を行う。 FIG. 7 is an explanatory view showing the stretching process. In this step, the corrugated tube 10C subjected to the cross-linking process in the above step is stretched so that the internal space becomes large. In this step, the enlargement process is performed by the next enlargement device 80.
　拡大装置８０は、架橋処理されたコルゲートチューブ１０Ｃを巻取収容したリール８２と、その下流側のリール８８と、リール８２、８８の間に設けられた加熱装置８４と、リール８２、８８の間であって加熱装置８４の下流側に設けられたダイ８６とを備える。 The enlarging device 80 includes a reel 82 that winds and accommodates the corrugated tube 10 </ b> C subjected to the crosslinking treatment, a reel 88 on the downstream side thereof, a heating device 84 provided between the reels 82, 88, and the reels 82, 88. And a die 86 provided on the downstream side of the heating device 84.
　コルゲートチューブ１０Ｃのリール８２側の端部等には、気体を供給するための気体供給装置が連結されており、コルゲートチューブ１０Ｃ内には当該コルゲートチューブ１０Ｃを拡大させるための空気が供給されている。加熱装置８４は、ヒーター等を有しており、リール８２から引出されたコルゲートチューブ１０Ｃを加熱可能に構成されている。ダイ８６は、コルゲートチューブ１０Ｃの外径寸法よりも大きな内径寸法の挿通孔８６ｈが形成された部材であり、コルゲートチューブ１０Ｃが拡大された状態で本挿通孔８６ｈ内を通ることで、その外径寸法が当該挿通孔８６ｈの内径寸法に応じた大きさとなるように仕上げられる。 A gas supply device for supplying a gas is connected to an end of the corrugated tube 10C on the reel 82 side, and the air for expanding the corrugated tube 10C is supplied into the corrugated tube 10C. . The heating device 84 includes a heater and the like, and is configured to be able to heat the corrugated tube 10 </ b> C drawn from the reel 82. The die 86 is a member in which an insertion hole 86h having an inner diameter larger than the outer diameter of the corrugated tube 10C is formed, and the outer diameter of the die 86 passes through the main insertion hole 86h in an enlarged state. The size is finished so as to be a size corresponding to the inner diameter of the insertion hole 86h.
　そして、リール８２から引出されたコルゲートチューブ１０Ｃは、加熱装置８４にて加熱されて軟化された後、その内部に供給された気体によってその径方向外側に拡大されつつ、ダイ８６の挿通孔８６ｈ内に送込まれる。これにより、熱収縮コルゲートチューブ１０Ｂは、挿通孔８６ｈの内径寸法と同じ外形寸法の筒形状となるように仕上げられる。そして、この熱収縮コルゲートチューブ１０Ｂは、冷却後、リール８８によって巻取って収容される。 The corrugated tube 10 </ b> C pulled out from the reel 82 is heated and softened by the heating device 84, and then expanded radially outward by the gas supplied to the corrugated tube 10 </ b> C. Sent to. Thereby, the heat-shrinkable corrugated tube 10B is finished so as to have a cylindrical shape having the same outer dimensions as the inner diameter of the insertion hole 86h. And this heat contraction corrugated tube 10B is wound up and accommodated by the reel 88 after cooling.
　コルゲートチューブ１０Ｃを拡大させる構成は、上記例に限られない。例えば、コルゲートチューブ１０Ｃの外周部をバキュームして拡大させる構成、コルゲートチューブ１０Ｃ内に円錐状の拡大治具を挿入して、コルゲートチューブ１０Ｃを拡大させる構成等を採用することができる。 The configuration for expanding the corrugated tube 10C is not limited to the above example. For example, a configuration for vacuuming and expanding the outer peripheral portion of the corrugated tube 10C, a configuration for expanding the corrugated tube 10C by inserting a conical expanding jig into the corrugated tube 10C, and the like can be adopted.
　図８～図１０は、上記各工程において、コルゲートチューブの重合体の状態を概念的に示す説明図である。 8 to 10 are explanatory diagrams conceptually showing the state of the polymer of the corrugated tube in each of the above steps.
　まず、コルゲートチューブ１０Ｃが金型成形された直後の状態では、図８に示すように、複数の重合体は、ばらばらな状態で存在している。 First, in a state immediately after the corrugated tube 10C is molded, as shown in FIG. 8, a plurality of polymers exist in a dispersed state.
　この状態で、架橋処理を施すと、図９に示すように、複数の重合体が、その時の形状、即ち、コルゲートチューブ形状を記憶した状態で架橋し、もって、コルゲートチューブ形状を記憶した架橋構造を得ることができる。 When cross-linking treatment is performed in this state, as shown in FIG. 9, a plurality of polymers are cross-linked in a state where the shape at that time, that is, the corrugated tube shape is memorized, and thus a cross-linked structure memorized in the corrugated tube shape Can be obtained.
　この後、コルゲートチューブ１０Ｃを加熱する。加熱温度は、コルゲートチューブ１０Ｃを引き伸すことができるが、溶融点未満の温度である。すると、図１０に示すように、前記架橋構造がコルゲートチューブ形状を記憶した状態のまま引き伸されることになる。この後、コルゲートチューブ１０Ｃを引き伸したものが冷却されると、コルゲートチューブ形状を記憶した架橋構造を含んだまま筒形状に引き伸された状態で固化し、熱収縮前の熱収縮コルゲートチューブ１０Ｂが製造される。 Thereafter, the corrugated tube 10C is heated. The heating temperature is a temperature below the melting point, although the corrugated tube 10C can be stretched. Then, as shown in FIG. 10, the bridging structure is stretched while the corrugated tube shape is memorized. After this, when the expanded one of the corrugated tube 10C is cooled, the corrugated tube 10C is solidified in a state of being stretched into a cylindrical shape while including the bridging structure storing the corrugated tube shape, and the heat-shrinkable corrugated tube 10B before heat shrinking. Is manufactured.
　これにより、上記熱収縮コルゲートチューブ１０Ｂを容易に製造することができる。 Thereby, the heat-shrinkable corrugated tube 10B can be easily manufactured.
　　＜配線モジュールの製造方法＞
　上記配線モジュール２０の製造方法について説明する。 <Manufacturing method of wiring module>
A method for manufacturing the wiring module 20 will be described.
　まず、複数の被覆電線が分岐しつつ結束されたワイヤーハーネス２３を準備する。ワイヤーハーネス２３は、端部にコネクタ３０が取付けられた分岐部分２３ａを少なくとも１つ含む（図１参照）。 First, a wire harness 23 in which a plurality of covered electric wires are bundled while being branched is prepared. The wire harness 23 includes at least one branch portion 23a to which the connector 30 is attached at the end (see FIG. 1).
　そして、図１１に示すように、上記ワイヤーハーネス２３の分岐部分２３ａ（少なくとも１つの被覆電線を含む）を、熱収縮前の熱収縮コルゲートチューブ１０Ｂに通す。より具体的には、端部のコネクタ３０及び分岐部分２３ａを、そのコネクタ３０側から熱収縮コルゲートチューブ１０Ｂの一端側開口に挿入してその軸方向に沿って押込んでいく。なお、１本の被覆電線又は１つに束ねられた複数の被覆電線２２を熱収縮コルゲートチューブ１０Ｂに通す場合等には、コネクタの反対側から、１本の被覆電線又は１つに束ねられた複数の被覆電線２２を熱収縮コルゲートチューブ１０Ｂに通すこともできる。 Then, as shown in FIG. 11, the branch portion 23a (including at least one covered wire) of the wire harness 23 is passed through the heat-shrinkable corrugated tube 10B before heat-shrinking. More specifically, the connector 30 and the branch portion 23a at the end are inserted into the opening on one end side of the heat-shrinkable corrugated tube 10B from the connector 30 side and pushed in along the axial direction. In addition, when passing one covered electric wire or a plurality of covered electric wires 22 bundled into one through the heat-shrinkable corrugated tube 10B, it was bundled into one covered electric wire or one from the opposite side of the connector. The plurality of covered electric wires 22 can be passed through the heat-shrinkable corrugated tube 10B.
　そして、熱収縮コルゲートチューブ１０Ｂの一端部がコネクタ３０のうち分岐部分２３ａ側の端部を覆うと共に、熱収縮コルゲートチューブ１０Ｂの残りの部分が分岐部分２３ａを覆うようにする。すなわち、少なくとも１本の被覆電線２２を含む分岐部分２３ａの延在方向の少なくとも一部及びこの端部に取付けられたコネクタ３０の少なくとも一部を、熱収縮コルゲートチューブ１０Ｂ内に配設する（工程(a1)）。 Then, one end of the heat shrink corrugated tube 10B covers the end of the connector 30 on the branching portion 23a side, and the remaining portion of the heat shrinking corrugated tube 10B covers the branching portion 23a. That is, at least a part in the extending direction of the branch portion 23a including at least one covered electric wire 22 and at least a part of the connector 30 attached to this end are disposed in the heat-shrinkable corrugated tube 10B (step). (a1)).
　そして、図１２に示すように、熱収縮コルゲートチューブ１０Ｂをヒーター等の加熱装置９９によって加熱して収縮させて、図１及び図２に示すように、分岐部分２３ａにコルゲートチューブ１０を装着する。ここでは、熱収縮コルゲートチューブ１０Ｂを、熱収縮可能な温度であって溶融する温度よりも低い温度で加熱することによって熱収縮する。これにより、熱収縮コルゲートチューブ１０Ｂのうち分岐部分２３ａを覆う部分を、コルゲートチューブ形状を呈するように熱収縮させて、第１部分１０ａを形成する（工程(a2)）。また、熱収縮コルゲートチューブ１０Ｂのうちコネクタ３０を覆う部分を、当該コネクタ３０の外周を覆うように熱収縮させて上記第２部分１０ｂを形成する(工程(a3))。なお、工程(a2)及び工程(a3)はいずれが先に行われてもよいし、同時に行われてもよい。これにより、上記配線モジュール２０が製造される。 Then, as shown in FIG. 12, the heat-shrinkable corrugated tube 10B is heated and contracted by a heating device 99 such as a heater, and the corrugated tube 10 is attached to the branching portion 23a as shown in FIGS. Here, the heat-shrinkable corrugated tube 10B is heat-shrinkable by heating at a temperature that is heat-shrinkable and lower than the melting temperature. Thereby, the part which covers the branch part 23a among heat-shrink corrugated tube 10B is heat-shrinked so that a corrugated tube shape may be exhibited, and the 1st part 10a is formed (process (a2)). Moreover, the part which covers the connector 30 among the heat contraction corrugated tubes 10B is thermally contracted so as to cover the outer periphery of the connector 30 to form the second part 10b (step (a3)). Note that either step (a2) or step (a3) may be performed first or simultaneously. Thereby, the wiring module 20 is manufactured.
　　＜効果等＞
　この配線モジュール２０及びその製造方法によると、熱収縮前の熱収縮コルゲートチューブ１０Ｂ内に、少なくとも１本の被覆電線２２の延在方向の少なくとも一部及びその端部に取付けられたコネクタ３０の少なくとも一部を容易に配設することができる。そして、この熱収縮コルゲートチューブ１０Ｂを、少なくとも１本の被覆電線２２のうちの少なくともコネクタ３０側の部分を覆った状態でコルゲートチューブ形状を呈するように熱収縮した第１部分１０ａと、コネクタ３０のうちの少なくとも被覆電線２２側の部分を覆った状態で熱収縮した第２部分１０ｂとを含むように、熱収縮させる。これにより、その延在方向全体に沿った切れ目が形成されていないコルゲートチューブ１０を、端部にコネクタ３０が取付けられた被覆電線２２に容易に装着することができる。この際、コルゲートチューブ１０は、コネクタ３０のうちの少なくとも被覆電線２２側の部分を覆った状態で熱収縮した部分１０ｂとを含むため、コネクタ３０と被覆電線２２の間の部分を止水できる。 <Effects>
According to the wiring module 20 and the manufacturing method thereof, at least a part of the extending direction of the at least one covered electric wire 22 and the connector 30 attached to the end of the at least one covered electric wire 22 are provided in the heat-shrinkable corrugated tube 10B before heat-shrinking. A part can be easily arranged. Then, the heat shrinking corrugated tube 10B is heat shrunk so as to exhibit a corrugated tube shape in a state of covering at least a portion of the at least one covered electric wire 22 on the connector 30 side, It heat-shrinks so that the 2nd part 10b heat-shrinked in the state which covered the part by the side of the covered electric wire 22 at least among them. Thereby, the corrugated tube 10 in which the cut | interruption along the whole extension direction is not formed can be easily mounted | worn with the covered electric wire 22 with which the connector 30 was attached to the edge part. At this time, the corrugated tube 10 includes the portion 10b that is thermally contracted in a state of covering at least a portion of the connector 30 on the side of the covered electric wire 22, so that the portion between the connector 30 and the covered electric wire 22 can be stopped.
　特に、分岐部分２３ａの端部に端部部品としてコネクタ３０が取付けられていると、当該コネクタ３０が邪魔となって、コルゲートチューブに通し難い。そこで、このような場合にも、比較的太い状態の熱収縮コルゲートチューブ１０Ｂに、分岐部分２３ａを、コネクタ３０を取付けた状態のまま通すことができ、コルゲートチューブ１０を分岐部分２３ａに容易に装着することができる。 Particularly, when the connector 30 is attached as an end part to the end of the branching portion 23a, the connector 30 is obstructed and is difficult to pass through the corrugated tube. Therefore, even in such a case, the branch portion 23a can be passed through the relatively thick heat-shrinkable corrugated tube 10B with the connector 30 attached, and the corrugated tube 10 can be easily attached to the branch portion 23a. can do.
　また、第２部分１０ｂは、コネクタ３０を覆うように熱収縮しているため、構成のコンパクト化にも貢献する。 Moreover, since the second portion 10b is thermally contracted so as to cover the connector 30, it contributes to a compact configuration.
　また、熱収縮コルゲートチューブ１０Ｂを熱収縮する際に、第１部分１０ａがコルゲートチューブ形状を呈するまで熱収縮させているため、第１部分１０ａは柔軟に曲ることができる。このため、分岐部分２３ａを曲げ可能にしつつ保護することが可能となる。 Also, when the heat-shrinkable corrugated tube 10B is heat-shrinked, the first portion 10a can be bent flexibly because it is heat-shrinked until the first portion 10a assumes a corrugated tube shape. For this reason, it becomes possible to protect the branch portion 23a while making it bendable.

The housing part 132 includes a housing main body part 132a whose outer peripheral surface has a rectangular parallelepiped outer peripheral surface shape, and a connecting part 132b that is connected to one end of the housing main body part 132a (the end on the side to which the covered electric wire 122 is connected).

　このハウジング部１３２には、各被覆電線１２２に対応する端子部が組込まれている。各端子部は、被覆電線１２２の導体に接続されている。各端子部と導体との接続は、超音波溶接、抵抗溶接、はんだ付、圧着等によってなされている。また、この端子部は、導体との接続部をハウジング部１３２内に埋設すると共に、その反対側の接続部を突出させた状態で、ハウジング部１３２にインサート成形等によって組込まれている。端子部の接続部は、ハウジング本体部１３２ａのうち上記連結部１３２ｂとは反対側に露出している。この接続部は、外部の電気部品側との接続に供される部分であり、ネジ止用の孔が形成された丸形端子形状、筒状のメス端子形状、ピン状或はタブ状のオス端子形状等に形成されている。端子部と接続された導体を含む被覆電線１２２は、ハウジング部１３２の連結部１３２ｂ側から外方に延出している。 In the housing part 132, terminal parts corresponding to the respective covered electric wires 122 are incorporated. Each terminal portion is connected to the conductor of the covered electric wire 122. Connection between each terminal portion and the conductor is made by ultrasonic welding, resistance welding, soldering, crimping, or the like. Further, the terminal portion is embedded in the housing portion 132 by insert molding or the like in a state where the connecting portion with the conductor is embedded in the housing portion 132 and the connecting portion on the opposite side is protruded. The connecting portion of the terminal portion is exposed on the opposite side of the housing main body portion 132a from the connecting portion 132b. This connection part is used for connection to the external electrical component side, and is a round terminal shape with a screw hole, a cylindrical female terminal shape, a pin-shaped or tab-shaped male. It is formed in a terminal shape or the like. The covered electric wire 122 including the conductor connected to the terminal portion extends outward from the connecting portion 132 b side of the housing portion 132.
　導電性シェル１３４は、ステンレス、アルミニウム、鉄等の金属板をプレス成形等することによって形成された部材であり、上記ハウジング部１３２のハウジング本体部１３２ａ及び連結部１３２ｂの周囲４方を覆う箱形状に形成されている。導電性シェル１３４は、連結部１３２ｂの外向き側及びその反対側で開口している。 The conductive shell 134 is a member formed by press-molding a metal plate such as stainless steel, aluminum, or iron, and has a box shape that covers four sides of the housing main body 132a and the connecting portion 132b of the housing portion 132. Is formed. The conductive shell 134 opens on the outward side of the connecting portion 132b and on the opposite side.
　そして、配線モジュール１２０が車両に組込まれた状態で、本コネクタ１３０が車両に等際された各種電気部品に接続され、被覆電線１２２が電気部品に電気的に接続される。この際、導電性シェル１３４は、電気部品の金属ケース等、車両の接地部位に電気的に接続される。 Then, in a state in which the wiring module 120 is incorporated in the vehicle, the connector 130 is connected to various electrical components that are equalized in the vehicle, and the covered electric wire 122 is electrically connected to the electrical components. At this time, the conductive shell 134 is electrically connected to a grounded portion of the vehicle such as a metal case of an electrical component.
　筒部材１５０は、被覆電線１２２を、コネクタ１３０から間隔をあけた位置で囲む筒状の部材である。筒部材１５０は、ここでは、アルミニウム、ステンレス又は鉄等の金属によって形成された導電性筒部材である。この筒部材１５０は、被覆電線１２２のうちコネクタ１３０から離れた部分を覆って保護する役割及び電磁的なシールドを行う役割を有する。もっとも、筒部材１５０が、導電性であることは必須ではなく、樹脂等の筒部材等であってもよい。 The cylindrical member 150 is a cylindrical member that surrounds the covered electric wire 122 at a position spaced from the connector 130. Here, the cylindrical member 150 is a conductive cylindrical member formed of a metal such as aluminum, stainless steel, or iron. The cylindrical member 150 has a role of covering and protecting a portion of the covered electric wire 122 away from the connector 130 and a role of performing electromagnetic shielding. However, it is not essential that the cylindrical member 150 is conductive, and a cylindrical member such as a resin may be used.
　筒部材１５０を、コネクタ１３０に対して間隔をあけた位置に設けているのは、筒部材１５０とコネクタ１３０との間で、被覆電線１２２を曲げ可能にするためである。つまり、筒部材１５０を車両に固定すると共に、コネクタ１３０を車両の電気部品に接続した状態で、それらの間を曲げ容易にすることで、それらの組込作業性を良好にすることができる。このため、筒部材１５０とコネクタ１３０との間には、それらの間で被覆電線１２２を曲げ容易にする程度の間隔が設けられていればよく、例えば、５ｃｍ～３０ｃｍの間隔が設けられていればよい。 The reason why the cylindrical member 150 is provided at a position spaced from the connector 130 is to allow the covered electric wire 122 to be bent between the cylindrical member 150 and the connector 130. That is, while fixing the cylindrical member 150 to the vehicle and connecting the connector 130 to an electrical component of the vehicle, it is easy to bend between them, so that their workability can be improved. For this reason, it is only necessary to provide an interval between the cylindrical member 150 and the connector 130 so that the covered electric wire 122 can be easily bent between them. For example, an interval of 5 cm to 30 cm may be provided. That's fine.
　導電性被覆部材１６０は、筒部材１５０とコネクタ１３０との間で被覆電線１２２を覆う筒状の部材であって、柔軟かつ導電性を有する部材である。かかる導電性被覆部材１６０は、例えば、金属線等の導線が筒状に編み込まれた編組、金属線等の導線が縦横に交差するように織られた網目構造を有する金属布又は金属網が筒形状をなすように丸められた構成のもの、等が用いられる。かかる導電性被覆部材１６０は、被覆電線１２２を覆いつつ、柔軟に曲ることができる。 The conductive covering member 160 is a tubular member that covers the covered electric wire 122 between the tubular member 150 and the connector 130, and is a flexible and conductive member. Such a conductive covering member 160 is, for example, a braid in which conducting wires such as metal wires are knitted in a cylindrical shape, or a metal cloth or metal mesh having a mesh structure woven so that conducting wires such as metal wires intersect vertically and horizontally. The thing of the structure rounded so that it may make a shape, etc. are used. The conductive covering member 160 can bend flexibly while covering the covered electric wire 122.
　導電性被覆部材１６０の一端部は、上記導電性シェル１３４に電気的に接続されている。ここでは、導電性被覆部材１６０の一端部を、コネクタ１３０の連結部１３２ｂ外周で導電性シェル１３４の外周に被せ、そのさらに外周囲に金属筒形状のかしめ部材１６２を配設してかしめ部材１６２をかしめることによって、導電性被覆部材１６０の一端部が、上記導電性シェル１３４に電気的に接続されている。 One end of the conductive covering member 160 is electrically connected to the conductive shell 134. Here, one end portion of the conductive covering member 160 is placed on the outer periphery of the conductive shell 134 at the outer periphery of the connecting portion 132b of the connector 130, and a caulking member 162 having a metal cylindrical shape is disposed on the outer periphery thereof. By caulking, one end of the conductive covering member 160 is electrically connected to the conductive shell 134.
　また、導電性被覆部材１６０の他端部は、筒部材１５０に電気的に接続されている。ここでは、導電性被覆部材１６０の他端部を、筒部材１５０のうちコネクタ１３０側の端部の外周に被せ、そのさらに外周囲に金属筒形状のかしめ部材１６４を配設してかしめ部材１６４をかしめることによって、導電性被覆部材１６０の他端部が、上記筒部材１５０に電気的に接続されている。 Also, the other end of the conductive covering member 160 is electrically connected to the cylindrical member 150. Here, the other end portion of the conductive covering member 160 is put on the outer periphery of the end portion on the connector 130 side of the cylindrical member 150, and a caulking member 164 having a metal cylindrical shape is further disposed on the outer periphery thereof. By caulking, the other end portion of the conductive covering member 160 is electrically connected to the cylindrical member 150.
　これにより、被覆電線１２２が、筒部材１５０及び導電性被覆部材１６０によって囲まれると共に、筒部材１５０及び導電性被覆部材１６０が導電性シェル１３４に電気的に接続され、当該導電性シェル１３４を通じて接地可能となる。これにより、被覆電線１２２を電磁的に遮蔽することができる。 Accordingly, the covered electric wire 122 is surrounded by the cylindrical member 150 and the conductive covering member 160, and the cylindrical member 150 and the conductive covering member 160 are electrically connected to the conductive shell 134 and grounded through the conductive shell 134. It becomes possible. Thereby, the covered electric wire 122 can be shielded electromagnetically.
　上記複数の被覆電線１２２のうち少なくともコネクタ１３０側の部分に、コルゲートチューブ１１０が装着されている。 The corrugated tube 110 is attached to at least a portion of the plurality of covered electric wires 122 on the connector 130 side.
　コルゲートチューブ１１０は、上記第１実施形態と同様に、熱収縮コルゲートチューブ１０Ｂにより構成されている。 The corrugated tube 110 is configured by a heat-shrinkable corrugated tube 10B as in the first embodiment.
　ここでは、コルゲートチューブ１１０は、上記被覆電線１２２のうちの少なくともコネクタ１３０側の部分を覆った状態でコルゲートチューブ形状を呈するように熱収縮した第１部分１１０ａと、コネクタ１３０のうち少なくとも被覆電線１２２側の部分を覆った状態で熱収縮した第２部分１１０ｂと、筒部材１５０のうち被覆電線１２２側の部分を覆った状態で熱収縮した第３部分１１０ｃとを含む。 Here, the corrugated tube 110 includes a first portion 110a that is thermally shrunk so as to have a corrugated tube shape in a state where at least a portion of the covered electric wire 122 on the connector 130 side is covered, and at least the covered electric wire 122 of the connector 130. A second portion 110b thermally contracted in a state of covering the portion on the side, and a third portion 110c thermally contracted in a state of covering a portion on the covered wire 122 side of the cylindrical member 150.
　すなわち、１つのコルゲートチューブ１１０が、コネクタ１３０のうち被覆電線１２２側の部分から、被覆電線１２２のうちのコネクタ１３０側の部分及び筒部材１５０のうち被覆電線１２２側の部分に亘って全体を覆っている。 That is, one corrugated tube 110 covers the whole from the portion on the covered wire 122 side of the connector 130 to the portion on the connector 130 side of the covered wire 122 and the portion on the covered wire 122 side of the cylindrical member 150. ing.
　そして、このコルゲートチューブ１１０のうち被覆電線１２２を覆う第１部分１１０ａがコルゲートチューブ形状を呈するように熱収縮している。この第１部分１１０ａは、導電性被覆部材１６０を介して被覆電線１２２を覆っている。従って、導電性被覆部材１６０は、コルゲートチューブ１１０によって保護されると共に止水状態に保たれる。 And the 1st part 110a which covers the covered electric wire 122 among this corrugated tube 110 is thermally contracted so that a corrugated tube shape may be exhibited. The first portion 110 a covers the covered electric wire 122 via the conductive covering member 160. Therefore, the conductive covering member 160 is protected by the corrugated tube 110 and kept in a water-stopped state.
　また、第１部分１１０ａは、複数の被覆電線１２２を一括して覆っているため、個々の被覆電線１２２を別々に覆う場合と比べて、比較的簡易に当該複数の被覆電線１２２を覆って保護することができる。 Moreover, since the 1st part 110a has covered the some covered electric wire 122 collectively, compared with the case where each covered electric wire 122 is covered separately, it covers the said some covered electric wire 122 comparatively easily. can do.
　また、ここでは、第１部分１１０ａは、その延在方向に沿って太環状部１２と細環状部１４とが交互に連続して設けられた筒状をなすコルゲートチューブ形状に形成されている。従って、第１部分１１０ａは、比較的容易に曲ることができる。 Further, here, the first portion 110a is formed in a corrugated tube shape having a cylindrical shape in which the thick annular portions 12 and the narrow annular portions 14 are alternately and continuously provided along the extending direction. Accordingly, the first portion 110a can be bent relatively easily.
　また、コルゲートチューブ１１０のうちコネクタ１３０を覆う第２部分１１０ｂは、コネクタ１３０の連結部１３２ｂの外周を、導電性被覆部材１６０の一端部及びかしめ部材１６２を介して覆った状態で熱収縮している。好ましくは、第２部分１１０ｂは、その内周部とコネクタ１３０の外周部との隙間をなるべく少なくするように、当該コネクタ１３０の連結部１３２ｂの外周形状に応じた形状に熱収縮している。 The second portion 110b of the corrugated tube 110 covering the connector 130 is thermally contracted in a state where the outer periphery of the connecting portion 132b of the connector 130 is covered with the one end portion of the conductive coating member 160 and the caulking member 162. Yes. Preferably, the second portion 110b is thermally contracted into a shape corresponding to the outer peripheral shape of the connecting portion 132b of the connector 130 so as to reduce the gap between the inner peripheral portion and the outer peripheral portion of the connector 130 as much as possible.
　コルゲートチューブ１１０の内周部、好ましくは、第２部分１１０ｂと連結部１３２ｂとの間にホットメルト等の接着剤１１１ｂが介在している。これにより、第２部分１１０ｂとコネクタ１３０の連結部１３２ｂとの隙間を当該接着剤１１１ｂが埋めることができる。 An adhesive 111b such as hot melt is interposed between the inner peripheral portion of the corrugated tube 110, preferably between the second portion 110b and the connecting portion 132b. Accordingly, the adhesive 111b can fill the gap between the second portion 110b and the connecting portion 132b of the connector 130.
　なお、上記第１実施形態で説明したように、第２部分１１０ｂには、コネクタ１３０を覆った状態で、コルゲートチューブ形状に応じた段差が形成されていてもよいし、そのような段差がない筒形状に形成されていてもよい。 As described in the first embodiment, the second portion 110b may have a step corresponding to the corrugated tube shape in a state where the connector 130 is covered, and there is no such step. It may be formed in a cylindrical shape.
　図１７に示す変形例に係る配線モジュール１２０Ｂでは、コルゲートチューブ１１０Ｂのうちコネクタ１３０を覆った状態で熱収縮した第２部分１１０Ｂｂには、コルゲートチューブ形状に応じた段差が形成されていない。かかる第２部分１１０Ｂｂは、連結部１３２ｂが比較的大きく、熱収縮コルゲートチューブ１０Ｂの収縮度合が小さい結果、コルゲートチューブ形状に応じた段差が生じない形状として形成されたものであってもよい。あるいは、熱収縮コルゲートチューブ１０Ｂのうちコネクタ１３０を覆う部分が、コルゲートチューブ形状に熱収縮せず、段差がない筒形状に熱収縮する構成である結果、段差の無い第２部分１１０Ｂｂが形成されたものであってもよい。 In the wiring module 120B according to the modification shown in FIG. 17, the step corresponding to the shape of the corrugated tube is not formed in the second portion 110Bb of the corrugated tube 110B that is thermally contracted while covering the connector 130. The second portion 110Bb may be formed in a shape in which a step corresponding to the corrugated tube shape does not occur as a result of the relatively large connecting portion 132b and a small degree of contraction of the heat-shrinkable corrugated tube 10B. Alternatively, the portion of the heat-shrinkable corrugated tube 10B that covers the connector 130 is not heat-shrinked into a corrugated tube shape and is heat-shrinked into a cylindrical shape without a step, resulting in the formation of a second portion 110Bb without a step. It may be a thing.
　なお、コルゲートチューブ１１０のうち上記第１部分１１０ａと第２部分１１０ｂとの間には、第１部分１１０ａから第２部分１１０ｂに向けて徐々に拡径する部分が形成されている。 In the corrugated tube 110, a portion that gradually increases in diameter from the first portion 110a toward the second portion 110b is formed between the first portion 110a and the second portion 110b.
　また、コルゲートチューブ１１０のうち筒部材１５０を覆う第３部分１１０ｃは、筒部材１５０のうち被覆電線１２２側の外周を、導電性被覆部材１６０の他端部及びかしめ部材１６４を介して覆った状態で熱収縮している。好ましくは、第３部分１１０ｃは、その内周部と筒部材１５０の外周部との隙間をなるべく少なくするように、当該筒部材１５０の外周形状に応じた形状に熱収縮している。 The third portion 110c of the corrugated tube 110 that covers the cylindrical member 150 covers the outer periphery of the cylindrical member 150 on the side of the covered electric wire 122 via the other end of the conductive coating member 160 and the caulking member 164. It is heat shrinking. Preferably, the third portion 110c is thermally contracted into a shape corresponding to the outer peripheral shape of the cylindrical member 150 so as to reduce the gap between the inner peripheral portion and the outer peripheral portion of the cylindrical member 150 as much as possible.
　コルゲートチューブ１１０の内周部、好ましくは、第３部分１１０ｃと筒部材１５０との間にホットメルト等の接着剤１１１ｃが介在している。これにより、第３部分１１０ｃと筒部材１５０との隙間を当該接着剤１１１ｃが埋めることができる。 An adhesive 111c such as hot melt is interposed between the inner peripheral portion of the corrugated tube 110, preferably between the third portion 110c and the cylindrical member 150. Thereby, the adhesive 111c can fill the gap between the third portion 110c and the cylindrical member 150.
　なお、上記したように、第３部分１１０ｃには、筒部材１５０を覆った状態で、コルゲートチューブ形状に応じた段差が形成されていてもよいし、そのような段差がない筒形状に形成されていてもよい。 As described above, the third portion 110c may be formed with a step corresponding to the shape of the corrugated tube in a state of covering the cylindrical member 150, or may be formed in a cylindrical shape without such a step. It may be.
　図１７に示す変形例に係る配線モジュール１２０Ｂでは、コルゲートチューブ１１０Ｂのうち筒部材１５０を覆った状態で熱収縮した第３部分１１０Ｂｃには、コルゲートチューブ形状に応じた段差が形成されていない。かかる第３部分１１０Ｂｃは、筒部材１５０が比較的大きく、熱収縮コルゲートチューブ１０Ｂの収縮度合が小さい結果、コルゲートチューブ形状に応じた段差が生じない形状として形成されたものであってもよい。あるいは、熱収縮コルゲートチューブ１０Ｂのうち筒部材１５０を覆う部分が、コルゲートチューブ形状に熱収縮せず、段差がない筒形状に熱収縮する構成である結果、段差の無い第３部分１１０Ｂｃが形成されたものであってもよい。 In the wiring module 120B according to the modification shown in FIG. 17, the step corresponding to the corrugated tube shape is not formed in the third portion 110Bc of the corrugated tube 110B that is thermally contracted in a state of covering the cylindrical member 150. The third portion 110Bc may be formed in a shape in which a step corresponding to the corrugated tube shape does not occur as a result of the relatively large cylindrical member 150 and a small degree of contraction of the heat-shrinkable corrugated tube 10B. Alternatively, the portion of the heat-shrinkable corrugated tube 10B that covers the cylindrical member 150 does not thermally shrink into a corrugated tube shape and is heat-shrinked into a cylindrical shape without a step, resulting in the formation of a third portion 110Bc without a step. It may be.
　なお、本配線モジュール１２０において、被覆電線１２２の他端部は、上記した一端部と同様構成であってもよいし、別構造によって他の電気部品に接続される構成であってもよい。 In the wiring module 120, the other end of the covered electric wire 122 may have the same configuration as the one end described above, or may be connected to another electrical component by another structure.
　　＜配線モジュールの製造方法＞
　上記配線モジュール１２０の製造方法について説明する。 <Manufacturing method of wiring module>
A method for manufacturing the wiring module 120 will be described.
　まず、複数の被覆電線１２２の一端部にコネクタ１３０が取付けられ、被覆電線１２２に対してコネクタ１３０から離れた位置に筒部材１５０が被せられ、さらに、導電性被覆部材１６０がコネクタ１３０の導電性シェル１３４及び筒部材１５０に電気的に接続された状態で被覆電線１２２を覆ったもの、を準備する。そして、これを、図１５に示すように、熱収縮コルゲートチューブ１０Ｂに通す。なお、ここでは、被覆電線１２２等を、コネクタ１３０側から熱収縮コルゲートチューブ１０Ｂ内に通しているが、その反対側から熱収縮コルゲートチューブ１０Ｂ内に通してもよい。 First, the connector 130 is attached to one end portion of the plurality of covered electric wires 122, the cylindrical member 150 is put on a position away from the connector 130 with respect to the covered electric wires 122, and the conductive covering member 160 is further conductive of the connector 130. What covered the covered electric wire 122 in the state electrically connected to the shell 134 and the cylindrical member 150 is prepared. Then, this is passed through the heat-shrinkable corrugated tube 10B as shown in FIG. Here, the covered electric wire 122 and the like are passed through the heat-shrinkable corrugated tube 10B from the connector 130 side, but may be passed through the heat-shrinkable corrugated tube 10B from the opposite side.
　そして、熱収縮コルゲートチューブ１０Ｂの一端部がコネクタ１３０のうち連結部１３２ｂを覆うと共に、熱収縮コルゲートチューブ１０Ｂの他端部が筒部材１５０のうち被覆電線１２２側の端部を覆うようにする。また、コネクタ１３０と筒部材１５０との間で、熱収縮コルゲートチューブ１０Ｂが複数の被覆電線１２２を一括して覆うようにする。 The one end portion of the heat-shrinkable corrugated tube 10B covers the connecting portion 132b of the connector 130, and the other end portion of the heat-shrinkable corrugated tube 10B covers the end portion of the cylindrical member 150 on the covered wire 122 side. Further, the heat-shrinkable corrugated tube 10 </ b> B covers the plurality of covered electric wires 122 at a time between the connector 130 and the cylindrical member 150.
　そして、図１６に示すように、熱収縮コルゲートチューブ１０Ｂをヒーター等の加熱装置９９によって加熱して収縮させて、図１３及び図１４に示すように、被覆電線１２２にコルゲートチューブ１１０を装着する。ここでは、熱収縮コルゲートチューブ１０Ｂを、熱収縮可能な温度であって溶融する温度よりも低い温度で加熱することによって熱収縮する。これにより、熱収縮コルゲートチューブ１０Ｂのうち、コネクタ１３０と筒部材１５０との間で被覆電線１２２を覆う部分を、コルゲートチューブ形状を呈するように熱収縮させて、第１部分１１０ａを形成する。また、熱収縮コルゲートチューブ１０Ｂのうちコネクタ１３０の連結部１３２ｂを覆う部分を、当該連結部１３２ｂの外周を覆うように熱収縮させて上記第２部分１１０ｂを形成する。さらに、熱収縮コルゲートチューブ１０Ｂのうち筒部材１５０を覆う部分を、当該筒部材１５０の外周を覆うように熱収縮させて上記第３部分１１０ｃを形成する。なお、上記各熱収縮の工程は、いずれが先に行われてもよいし、同時に行われてもよい。これにより、上記配線モジュール１２０が製造される。 Then, as shown in FIG. 16, the heat-shrinkable corrugated tube 10 </ b> B is heated and contracted by a heating device 99 such as a heater, and the corrugated tube 110 is attached to the covered electric wire 122 as shown in FIGS. 13 and 14. Here, the heat-shrinkable corrugated tube 10B is heat-shrinkable by heating at a temperature that is heat-shrinkable and lower than the melting temperature. Thereby, the part which covers the covered electric wire 122 between the connector 130 and the cylindrical member 150 among the heat-shrinkable corrugated tube 10B is heat-shrinked so as to exhibit the corrugated tube shape, thereby forming the first portion 110a. Moreover, the part which covers the connection part 132b of the connector 130 among the heat contraction corrugated tubes 10B is thermally contracted so as to cover the outer periphery of the connection part 132b, thereby forming the second part 110b. Furthermore, the part which covers the cylindrical member 150 among the heat-shrinkable corrugated tubes 10B is thermally contracted so as to cover the outer periphery of the cylindrical member 150, thereby forming the third part 110c. Note that any of the heat shrinking steps may be performed first or simultaneously. Thereby, the wiring module 120 is manufactured.
　　＜効果等＞
　第２実施形態に係る配線モジュール１２０及びその製造方法によると、上記第１実施形態と同様の作用効果を得ることができる。 <Effects>
According to the wiring module 120 and the manufacturing method thereof according to the second embodiment, it is possible to obtain the same effects as those of the first embodiment.
　加えて、コルゲートチューブ１１０は、筒部材１５０を覆うように熱収縮した第３部分１１０ｃを含むため、筒部材１５０とコネクタ１３０との間で、被覆電線１２２を止水することができる。換言すれば、主として１つのコルゲートチューブ１１０によって、筒部材１５０とコネクタ１３０との間を止水することができ、部品コスト、部品点数の削減、構成の簡易化等が可能となる。 In addition, since the corrugated tube 110 includes the third portion 110 c that is thermally contracted so as to cover the cylindrical member 150, the covered electric wire 122 can be stopped between the cylindrical member 150 and the connector 130. In other words, the water between the cylindrical member 150 and the connector 130 can be stopped mainly by the single corrugated tube 110, and the part cost, the number of parts can be reduced, the configuration can be simplified, and the like.
　また、筒部材１５０は、導電性を有する部材とされ、コネクタ１３０がその外周に設けられた導電性シェル１３４を含んでいる。そして、柔軟な導電性被覆部材１６０が、筒部材１５０と導電性シェル１３４に電気的に接続されると共に、筒部材１５０と導電性シェル１３４との間で被覆電線１２２を覆っている。その上で、コルゲートチューブ１１０が、導電性被覆部材１６０を介して被覆電線１２２を覆っている。このため、筒部材１５０と導電性シェル１３４との間に導電性被覆部材１６０を設けることによって、この部分で被覆電線１２２を電磁的に遮蔽する構成において、当該導電性被覆部材１６０をも、コルゲートチューブ１１０によって覆って止水等することができる。 The cylindrical member 150 is a conductive member, and includes a conductive shell 134 provided with a connector 130 on the outer periphery thereof. A flexible conductive covering member 160 is electrically connected to the cylindrical member 150 and the conductive shell 134 and covers the covered electric wire 122 between the cylindrical member 150 and the conductive shell 134. In addition, the corrugated tube 110 covers the covered electric wire 122 via the conductive covering member 160. For this reason, by providing the conductive covering member 160 between the cylindrical member 150 and the conductive shell 134, the conductive covering member 160 is also corrugated in a configuration in which the covered electric wire 122 is electromagnetically shielded at this portion. The water can be stopped by covering with the tube 110.
　また、コルゲートチューブ１１０が複数の被覆電線１２２を一括して覆っているため、その構成の簡易化が可能となる。 Moreover, since the corrugated tube 110 covers the plurality of covered electric wires 122 in a lump, the configuration can be simplified.

　上記複数の裸線状導体２２２のそれぞれにコルゲートチューブ２１０が装着されている。 A corrugated tube 210 is attached to each of the plurality of bare wire conductors 222.
　コルゲートチューブ２１０は、上記第１実施形態と同様に、熱収縮コルゲートチューブ１０Ｂにより構成されている。 The corrugated tube 210 is configured by the heat-shrinkable corrugated tube 10B as in the first embodiment.
　ここでは、コルゲートチューブ２１０は、上記裸線状導体２２２のうちの少なくとも端部接続部２３０側の部分を覆った状態でコルゲートチューブ形状を呈するように熱収縮した第１部分２１０ａと、端部接続部２３０のうち少なくとも裸線状導体２２２側の部分を覆った状態で熱収縮した第２部分２１０ｂとを含む。 Here, the corrugated tube 210 is connected to the first portion 210a thermally contracted so as to exhibit a corrugated tube shape in a state of covering at least a portion on the end connecting portion 230 side of the bare wire-like conductor 222, and an end connecting portion. And a second portion 210b thermally contracted in a state of covering at least a portion of the portion 230 on the bare wire conductor 222 side.
　すなわち、１つのコルゲートチューブ２１０が、端部接続部２３０のう裸線状導体２２２側の部分から裸線状導体２２２のうちの端部接続部２３０側の部分に亘って全体を覆っている。 That is, one corrugated tube 210 covers the entire portion from the portion on the bare wire conductor 222 side of the end connection portion 230 to the portion on the end connection portion 230 side of the bare wire conductor 222.
　そして、このコルゲートチューブ２１０のうち裸線状導体２２２を覆う第１部分２１０ａがコルゲートチューブ形状を呈するように熱収縮している。この第１部分２１０ａは、裸線状導体２２２を、他の絶縁性部分を介することなく、直接的に裸線状導体２２２を覆っている。従って、コルゲートチューブ２１０は、裸線状導体２２２をその周囲の導電性部分と接触しないように保つ絶縁部材としての役割を果す。もちろん、コルゲートチューブ２１０は、裸線状導体２２２を外傷等から保護すると共に止水状態に保たつ役割をも果す。 And the 1st part 210a which covers the bare wire conductor 222 among this corrugated tube 210 is thermally contracted so that a corrugated tube shape may be exhibited. The first portion 210a directly covers the bare wire conductor 222 without passing through another insulating portion. Accordingly, the corrugated tube 210 serves as an insulating member that keeps the bare wire conductor 222 from coming into contact with the surrounding conductive portions. Of course, the corrugated tube 210 plays a role of protecting the bare wire-like conductor 222 from a damage or the like and keeping it in a water-stopped state.
　また、ここでは、第１部分２１０ａは、その延在方向に沿って太環状部１２と細環状部１４とが交互に連続して設けられた筒状をなすコルゲートチューブ形状に形成されている。従って、第１部分２１０ａは、比較的容易に曲ることができる。 In addition, here, the first portion 210a is formed in a corrugated tube shape having a cylindrical shape in which the thick annular portions 12 and the narrow annular portions 14 are alternately and continuously provided along the extending direction. Accordingly, the first portion 210a can be bent relatively easily.
　また、コルゲートチューブ２１０のうち端部接続部２３０の突出導出部２３３を覆う第２部分２１０ｂは、突出導出部２３３の外周を覆った状態で熱収縮している。好ましくは、第２部分２１０ｂは、その内周部と突出導出部２３３の外周部との隙間をなるべく少なくするように、当該突出導出部２３３の外周形状に応じた形状に熱収縮している。 Further, the second portion 210b of the corrugated tube 210 that covers the protruding lead-out portion 233 of the end connection portion 230 is thermally contracted in a state of covering the outer periphery of the protruding lead-out portion 233. Preferably, the second portion 210b is thermally contracted into a shape corresponding to the outer peripheral shape of the protrusion derivation portion 233 so as to reduce the gap between the inner peripheral portion and the outer periphery of the protrusion derivation portion 233 as much as possible.
　コルゲートチューブ２１０の内周部、好ましくは、第２部分２１０ｂと突出導出部２３３との間にホットメルト等の接着剤２１１ｂが介在している。これにより、第２部分２１０ｂと突出導出部２３３との隙間を当該接着剤２１１ｂが埋めることができる。 An adhesive 211b such as hot melt is interposed between the inner peripheral portion of the corrugated tube 210, preferably between the second portion 210b and the protruding lead-out portion 233. Thereby, the adhesive 211b can fill the gap between the second portion 210b and the protruding lead-out portion 233.
　なお、上記第１実施形態で説明したように、第２部分２１０ｂには、突出導出部２３３を覆った状態で、コルゲートチューブ形状に応じた段差が形成されていてもよいし、そのような段差がない筒形状に形成されていてもよい。 As described in the first embodiment, a step corresponding to the corrugated tube shape may be formed in the second portion 210b while covering the protruding lead-out portion 233, and such a step may be formed. It may be formed in a cylindrical shape without any.
　なお、本配線モジュール２２０において、裸線状導体２２２の他端部は、上記した一端部と同様構成であってもよいし、別構造によって他の電気部品に接続される構成であってもよい。 In the wiring module 220, the other end of the bare wire conductor 222 may have the same configuration as the one end described above, or may be configured to be connected to another electrical component by another structure. .
　上記配線モジュール２２０は、第１実施形態又は第２実施形態と同様に、熱収縮コルゲートチューブ１０Ｂ内に、裸線状導体２２２及び突出導出部２３３を配設し状態で、熱収縮コルゲートチューブ１０Ｂを熱収縮させることによって、製造することができる。 Similar to the first embodiment or the second embodiment, the wiring module 220 has the bare wire conductor 222 and the protruding lead-out portion 233 disposed in the heat shrink corrugated tube 10B, and the heat shrink corrugated tube 10B is placed in the heat shrink corrugated tube 10B. It can be manufactured by heat shrinking.
　　＜効果等＞
　第３実施形態に係る配線モジュール２２０及びその製造方法によると、上記第１実施形態と同様の作用効果を得ることができる。 <Effects>
According to the wiring module 220 and the manufacturing method thereof according to the third embodiment, it is possible to obtain the same effects as those of the first embodiment.
　加えて、コルゲートチューブ２１０は、裸線状導体２２２を直接的に覆っているため、コルゲートチューブ２１０を、裸線状導体２２２の絶縁被覆として用いることができる。この場合、裸線状導体２２２として、編組又は金属布等を用いた場合に、その周囲を絶縁被覆する構成として適する。 In addition, since the corrugated tube 210 directly covers the bare wire conductor 222, the corrugated tube 210 can be used as an insulating coating for the bare wire conductor 222. In this case, when a braid, a metal cloth, or the like is used as the bare wire conductor 222, it is suitable as a configuration in which the periphery is insulated.
　また、コルゲートチューブ２１０は、端部接続部２３０の突出導出部２３３を覆った状態で熱収縮した第２部分２１０ｂを含むため、裸線状導体２２２が端部接続部２３０から導出される部分で、裸線状導体２２２を他の導電性部分からより確実に絶縁することができる。 Further, since the corrugated tube 210 includes the second portion 210b that is thermally contracted in a state of covering the protruding lead-out portion 233 of the end connection portion 230, the bare wire conductor 222 is a portion that is led out from the end connection portion 230. The bare wire conductor 222 can be more reliably insulated from other conductive portions.
　また、コルゲートチューブ２１０によって、裸線状導体２２２が、突出導出部２３３から延出する部分又はその他の部分で急激に曲ってしまうことを抑制できる。 Further, the corrugated tube 210 can suppress the bare wire conductor 222 from being bent suddenly at a portion extending from the protruding lead-out portion 233 or at other portions.
　また、第１及び第２実施形態において、熱収縮コルゲートチューブは、熱収縮してコネクタの電線接続側の少なくとも一部を覆っているが、熱収縮コルゲートチューブは、熱収縮してコネクタの全体を覆っていてもよい。 In the first and second embodiments, the heat-shrinkable corrugated tube is heat-shrinked to cover at least a part of the electric wire connection side of the connector, but the heat-shrinkable corrugated tube is heat-shrinked to cover the entire connector. It may be covered.
　さらに、第２実施形態において、導電性被覆部材は、筒部材の外周囲にかしめ接続されているとしたが、筒部材の内部に接続されていてもよい。 Further, in the second embodiment, the conductive coating member is caulked and connected to the outer periphery of the cylindrical member, but may be connected to the inside of the cylindrical member.
