Description

この発明は、ワイヤーハーネスを保護する技術に関する。   The present invention relates to a technique for protecting a wire harness.

自動車等に搭載されるワイヤーハーネスは、周辺部材から保護するため、保護材としてのコルゲートチューブに挿通された状態で配索経路に配索されることがある。このコルゲートチューブは、ワイヤーハーネスを内部に横入れする（延在方向に直交する方向から入れる）ために、周方向一部分に延在方向に沿って形成されたスリットを有していることもある。   In order to protect a wire harness mounted on an automobile or the like from peripheral members, the wire harness may be routed in a routing route in a state of being inserted through a corrugated tube as a protective material. The corrugated tube may have a slit formed along the extending direction in a part of the circumferential direction in order to horizontally insert the wire harness (from a direction orthogonal to the extending direction).

このようにスリットが形成されたコルゲートチューブにおいては、曲げ又はねじれ等が生じると、スリットが開いてワイヤーハーネスが外方に露出ないし飛び出してしまう恐れがある。   In the corrugated tube in which the slit is formed as described above, when bending or twisting occurs, the slit may open and the wire harness may be exposed or jumped outward.

これに対して、特許文献１には、ロック構造を有するコルゲートチューブが開示されている。このコルゲートチューブは、周方向に延びる複数の突条部が軸方向に所定ピッチで配されると共に軸方向にスリットが形成されている。突条部のうちスリットを挟む位置に配される両端部の間には、突条部の内側に収まる大きさのロック突起が設けられている。そして、突条部の両端部のうちの一方の端部がロック突起に被せられると、該一方の端部とロック突起とが係合する。   On the other hand, Patent Document 1 discloses a corrugated tube having a lock structure. In the corrugated tube, a plurality of protrusions extending in the circumferential direction are arranged at a predetermined pitch in the axial direction, and slits are formed in the axial direction. A lock protrusion having a size that fits inside the protrusion is provided between both ends of the protrusion that are arranged at positions where the slit is interposed. Then, when one end of both ends of the protrusion is put on the lock protrusion, the one end engages with the lock protrusion.

また、特許文献２にも、周方向の山部と谷部とを軸線方向に交互に設けていると共に軸線方向の全長にわたってスリットを有し、スリットを挟む山部の両側にそれぞれ係止用の凹凸部を連続して形成したメス側ロック部とオス側ロック部とを有するコルゲートチューブが開示されている。このコルゲートチューブは、オス側ロック部をメス側ロック部の内面側に挿入して凹部同士及び凸部同士を重ね合わせて嵌合し、スリットを閉鎖状態にロックできるように構成されている。   Also in Patent Document 2, circumferential ridges and valleys are alternately provided in the axial direction, and have slits over the entire length in the axial direction, and are respectively provided on both sides of the ridges sandwiching the slits. A corrugated tube having a female-side lock portion and a male-side lock portion in which concave and convex portions are continuously formed is disclosed. The corrugated tube is configured such that the male side lock portion is inserted into the inner surface side of the female side lock portion, the concave portions and the convex portions are overlapped and fitted, and the slit can be locked in a closed state.

しかしながら、特許文献１及び２のコルゲートチューブでも、より大きい曲げ又はねじれ等が生じると、突条部の両端部のうちの一方の端部がロック突起に対して浮いて外れてしまい、成型時の形態に復帰しようとする力によってスリットの口開きが生じる恐れがある。   However, even in the corrugated tube of Patent Documents 1 and 2, when larger bending or twisting occurs, one end of both ends of the ridge portion floats away from the lock projection, and at the time of molding. There is a possibility that the opening of the slit may occur due to the force of returning to the form.

特に、特許文献２のコルゲートチューブには、オス側ロック部及びメス側ロック部の各側方にそれぞれカット時の位置決め用凹部が形成されている。つまり、コルゲートチューブは、両方の位置決め用凹部で内外方向において薄肉となっているため、該位置決め用凹部で曲がり易く、各位置決め用凹部のスリット側に設けられたオス側ロック部とメス側ロック部とが内外方向において互いに離間する向きに変形し得る。そして、曲げ又はねじれ等の外力によっては、オス側ロック部とメス側ロック部とが内外方向において互いに離間して、スリットの口開きが生じてしまう。   In particular, the corrugated tube of Patent Document 2 is provided with a concave portion for positioning at the time of cutting on each side of the male lock portion and the female lock portion. That is, since the corrugated tube is thin in both the inner and outer directions at both positioning recesses, the corrugated tube is easily bent at the positioning recesses, and the male side lock portion and the female side lock portion provided on the slit side of each positioning recess. Can be deformed in a direction away from each other in the inner and outer directions. Then, depending on an external force such as bending or twisting, the male side lock portion and the female side lock portion are separated from each other in the inner and outer directions, and slit opening occurs.

そこで、本発明は、スリットの口開きをより効果的に抑制することを目的とする。   Then, an object of this invention is to suppress the opening of a slit more effectively.

第１の態様は、蛇腹構造の筒状に形成されているとともに軸方向に沿う１本のスリットが形成されたロック付コルゲートチューブであって、前記スリットの両側の縁部のうちの一方の縁部から軸方向に沿って形成された第１の溝部までの周方向の一部の範囲を占める雄ロック部と、前記スリットの両側の縁部のうちの他方の縁部から周方向の一部の範囲を占め、前記雄ロック部に対して外側から被せられて前記雄ロック部に重なって係止する部分である雌ロック部と、前記雄ロック部及び前記雌ロック部以外の残りの部分である本体部とを備え、前記本体部には、周方向に沿って延在する凸状の山部と凹状の谷部とが軸方向に交互に連続して形成されているとともに、前記雌ロック部の側方の１箇所にのみ、前記谷部の外周面と面一の底面を有するとともに前記周方向において前記山部を２分する前記軸方向に沿った一連の第２の溝部が形成されている。   1st aspect is a corrugated tube with a lock | rock with which the one slit along the axial direction was formed while being formed in the cylinder shape of a bellows structure, Comprising: One edge of the edge parts of the both sides of the said slit A male locking portion occupying a partial range in the circumferential direction from the portion to the first groove portion formed along the axial direction, and a portion in the circumferential direction from the other edge portion of both side edges of the slit A female lock portion that covers the male lock portion from the outside and overlaps and locks with the male lock portion, and the remaining portions other than the male lock portion and the female lock portion. A convex body and a concave valley that extend along the circumferential direction are formed alternately and continuously in the axial direction, and the female lock The bottom surface flush with the outer peripheral surface of the valley is only at one side of the part. A series of the second groove is formed along the axial direction of 2 minutes the ridges in the circumferential direction as well as.

第２の態様は、第１の態様に係るロック付コルゲートチューブであって、前記第２の溝部は、前記谷部から前記山部の外周部に向けて前記谷部の接線に沿って延在する側壁部を有する形状に形成されている。   A 2nd aspect is a corrugated tube with a lock | rock which concerns on a 1st aspect, Comprising: A said 2nd groove part is extended along the tangent of the said trough part toward the outer peripheral part of the said peak part from the said trough part. It is formed in a shape having a side wall portion.

第３の態様は、第１又は第２の態様に係るロック付コルゲートチューブであって、前記雄ロック部は、外周側において凸となる形状に形成された内側係止凸部を有し、前記雌ロック部は、内周側において凹となる形状に形成され前記内側係止凸部の外周部に対して嵌合される外側係止凹部を有している。   A third aspect is a corrugated tube with a lock according to the first or second aspect, wherein the male lock part has an inner locking convex part formed in a shape that is convex on the outer peripheral side, The female locking part has an outer locking recess that is formed in a concave shape on the inner peripheral side and is fitted to the outer peripheral part of the inner locking protrusion.

第１の態様に係るロック付コルゲートチューブによると、周方向に沿って延在する山部と谷部とが軸方向に交互に連続して設けられた本体部が、雌ロック部の側方の１箇所にのみ、谷部の外周面と面一の底面を有するとともに周方向において山部を２分する軸方向に沿った一連の第２の溝部を有する。そのため、曲げ又は捻れ等によって作用する応力が、本体部の第２の溝部の底部における曲げ変形によって緩和される。その結果、雄ロック部と雌ロック部とのロック状態をより確実に維持し、スリットの口開きをより効果的に抑制することができる。なお、雄ロック部及び雌ロック部は、当該コルゲートチューブにおけるスリットの両側の縁部を連結して保持するロック構造部を構成する。   According to the corrugated tube with a lock according to the first aspect, the main body portion in which the crests and troughs extending along the circumferential direction are provided alternately and continuously in the axial direction is provided on the side of the female lock. It has a series of 2nd groove parts along the axial direction which divides a mountain part into 2 in the circumferential direction while having the outer peripheral surface of a trough part and the same bottom face only in one place. For this reason, stress acting by bending or twisting is alleviated by bending deformation at the bottom of the second groove portion of the main body portion. As a result, the locked state between the male lock portion and the female lock portion can be more reliably maintained, and the opening of the slit can be more effectively suppressed. The male lock portion and the female lock portion constitute a lock structure portion that connects and holds the edge portions on both sides of the slit in the corrugated tube.

第２の態様に係るロック付コルゲートチューブによると、第２の溝部が谷部から山部の外周部に向けて谷部の接線に沿って延在する側壁部を有する形状に形成されているため、金型成型時に一対の金型を該側壁部に沿った方向に接離移動させて成型面のうちの幅方向端部で第２の溝部を形成できる。これにより、より小径なものでも第２の溝部を形成してスリットの口開きを効果的に抑制することができる。   According to the corrugated tube with a lock according to the second aspect, the second groove portion is formed in a shape having a side wall portion extending along the tangent line of the valley portion from the valley portion toward the outer peripheral portion of the mountain portion. The second groove can be formed at the end in the width direction of the molding surface by moving the pair of molds in the direction along the side wall when the mold is formed. Thereby, even if it is a smaller diameter, the 2nd groove part can be formed and the opening of a slit can be suppressed effectively.

第３の態様に係るロック付コルゲートチューブによると、雄ロック部が外周側において凸となる形状に形成された内側係止凸部を有し、雌ロック部が内周側において凹となる形状に形成され内側係止凸部の外周部に対して嵌合される外側係止凹部を有しているため、より確実に雄ロック部と雌ロック部とのロック状態を維持することができる。   According to the corrugated tube with a lock according to the third aspect, the male lock portion has an inner locking convex portion formed in a shape that is convex on the outer peripheral side, and the female lock portion is concave on the inner peripheral side. Since it has the outer side latching recessed part formed and fitted with respect to the outer peripheral part of an inner side latching convex part, the locked state of a male locking part and a female locking part can be maintained more reliably.

This corrugated tube 10 with a lock is a member used for protecting the wire harness 1 from the outside.

＜ロック付コルゲートチューブの概略＞
概略的には、ロック付コルゲートチューブ１０は、軸方向に沿う１本のスリットを有する蛇腹構造の筒状に形成された部材である。ここでは、ロック付コルゲートチューブ１０は、略円筒状に形成されている。そして、ロック付コルゲートチューブ１０は、スリットを通じて内側にワイヤーハーネス１を配設可能であり、ワイヤーハーネス１を内側に配設した状態で保護する。本ロック付コルゲートチューブ１０は、スリットを閉じた口閉じ状態に変形可能で、且つ、この口閉じ状態を維持可能に構成されている。以下、単に周方向又は軸方向と記す場合、ロック付コルゲートチューブ１０全体における周方向又は軸方向を指すものとする。 <Outline of corrugated tube with lock>
Schematically, the corrugated tube 10 with a lock is a member formed in a cylindrical shape having a bellows structure having one slit along the axial direction. Here, the corrugated tube 10 with a lock is formed in a substantially cylindrical shape. And the corrugated tube 10 with a lock | rock can arrange | position the wire harness 1 inside through a slit, and protects the wire harness 1 in the state arrange | positioned inside. The corrugated tube 10 with a lock can be deformed into a closed mouth with the slit closed, and can be maintained in the closed mouth. Hereinafter, when simply describing the circumferential direction or the axial direction, the circumferential direction or the axial direction of the entire corrugated tube 10 with a lock is meant.

ロック付コルゲートチューブ１０は、本体部２０と、ロック構造部３０とを備えている（図３参照）。より具体的には、ロック付コルゲートチューブ１０は、周方向におけるスリットを挟んだ両側縁部を含む部位にロック構造部３０の各部を有し、その各部を連結するようにロック構造部３０以外の残りの部分である断面視弧状の本体部２０が設けられている。また、ロック構造部３０は、周方向一部に第１の溝部３４を有している。この第１の溝部３４については、後に説明する。   The corrugated tube 10 with a lock includes a main body portion 20 and a lock structure portion 30 (see FIG. 3). More specifically, the corrugated tube 10 with a lock has each part of the lock structure part 30 at a portion including both side edges sandwiching the slit in the circumferential direction, and other than the lock structure part 30 so as to connect each part. A main portion 20 having a cross-sectional arc shape, which is the remaining portion, is provided. In addition, the lock structure portion 30 has a first groove portion 34 in a part in the circumferential direction. The first groove 34 will be described later.

本体部２０は、周方向に沿って延在する凸状の山部２２と凹状の谷部２４とが軸方向に交互に連続して設けられた形状に形成されている（図２参照）。すなわち、本体部２０は、周方向に直交する断面視において、波形状（略矩形波形状）を成している。山部２２及び谷部２４は、本体部２０の周方向全体に亘って延在している。そして、本体部２０は、軸方向に並ぶ山部２２同士又は谷部２４が近接又は離間する形態で曲げられる。   The main body 20 is formed in a shape in which convex ridges 22 and concave troughs 24 extending along the circumferential direction are provided alternately and continuously in the axial direction (see FIG. 2). That is, the main body 20 has a wave shape (substantially rectangular wave shape) in a cross-sectional view orthogonal to the circumferential direction. The mountain portion 22 and the valley portion 24 extend over the entire circumferential direction of the main body portion 20. And the main-body part 20 is bent in the form from which the peak parts 22 or the trough part 24 which are located in a line in the axial direction adjoin or separate.

また、本体部２０は、周方向一部に第２の溝部２６を有している。この第２の溝部２６については、ロック構造部３０を説明した後で詳述する。   The main body portion 20 has a second groove portion 26 in a part in the circumferential direction. The second groove 26 will be described in detail after the lock structure 30 is described.

ロック構造部３０は、周方向において、本体部２０の一端側でスリットを挟んだ一端部に設けられた雄ロック部３２と、本体部２０の他端側でスリットを挟んだ他端部に設けられた雌ロック部４２とを有する。このロック構造部３０は、ロック前形態からロック形態に変形可能に形成されている。ロック前形態とは、雄ロック部３２と雌ロック部４２とが周方向に並んだ（突き合わされた）形態である（図３参照）。また、ロック形態とは、雄ロック部３２の外周部に対して雌ロック部４２が被せられて係止した形態である（図４参照）。すなわち、ロック付コルゲートチューブ１０は、ロック構造部３０のロック形態で、スリットを閉じた口閉じ状態となる。   The lock structure portion 30 is provided in the circumferential direction at a male lock portion 32 provided at one end portion sandwiching the slit at one end side of the main body portion 20 and at the other end portion sandwiching the slit at the other end side of the main body portion 20. The female lock part 42 is provided. The lock structure 30 is formed to be deformable from a pre-lock configuration to a lock configuration. The form before locking is a form in which the male lock part 32 and the female lock part 42 are aligned (abutted) in the circumferential direction (see FIG. 3). Further, the lock form is a form in which the female lock part 42 is put on the outer peripheral part of the male lock part 32 and locked (see FIG. 4). That is, the corrugated tube 10 with a lock is in the closed form with the slit closed in the lock form of the lock structure 30.

雄ロック部３２は、第１の溝部３４と、内側係止凸部３６とを有している。この雄ロック部３２は、スリットの両側の縁部のうちの一方の縁部から軸方向に沿って形成された第１の溝部３４までの周方向の一部の範囲を占める。   The male lock portion 32 has a first groove portion 34 and an inner locking convex portion 36. The male lock portion 32 occupies a partial range in the circumferential direction from one edge portion of both edge portions of the slit to the first groove portion 34 formed along the axial direction.

第１の溝部３４は、後述する雌ロック部４２のスリット側端部が嵌り込む部分である。この第１の溝部３４は、本体部２０の周方向一端側で山部２２のスリット側に設けられ、山部２２より内周側に凹となる形状に形成された部分である。より具体的には、第１の溝部３４は、山部２２の内周側端部と同周上（谷部２４の同周上）に底部を有している。また、第１の溝部３４は、底部の周方向における寸法が、少なくともロック付コルゲートチューブ１０の厚さ寸法より大きく設定されている。   The 1st groove part 34 is a part into which the slit side edge part of the female locking part 42 mentioned later fits. The first groove portion 34 is a portion that is provided on the slit side of the peak portion 22 on one end side in the circumferential direction of the main body portion 20, and is formed in a concave shape on the inner peripheral side from the peak portion 22. More specifically, the first groove portion 34 has a bottom portion on the same circumference as the inner peripheral side end portion of the peak portion 22 (on the same circumference of the valley portion 24). Moreover, the dimension in the circumferential direction of the bottom part of the 1st groove part 34 is set larger than the thickness dimension of the corrugated tube 10 with a lock | rock at least.

内側係止凸部３６は、後述する雌ロック部４２の外側係止凹部４４に対して嵌合する部分である。この内側係止凸部３６は、第１の溝部３４のスリット側に連続し、外周側において凸となる形状に形成されている。ここでは、内側係止凸部３６は、突出寸法が山部２２の突出寸法より小さく、軸方向寸法も山部２２の軸方向寸法より小さく設定されている。この内側係止凸部３６は、ロック付コルゲートチューブ１０のうち、周方向においてスリットを挟んだ一端部に設けられている。   The inner locking convex portion 36 is a portion that fits into an outer locking concave portion 44 of the female lock portion 42 described later. The inner locking convex portion 36 is formed in a shape that is continuous with the slit side of the first groove portion 34 and is convex on the outer peripheral side. Here, the inner locking convex portion 36 has a projecting dimension smaller than the projecting dimension of the peak portion 22 and an axial dimension smaller than the axial dimension of the peak portion 22. The inner locking projection 36 is provided at one end of the corrugated tube 10 with a lock with a slit in the circumferential direction.

また、雄ロック部３２のうち、谷部２４のスリット側に位置する部分は、谷部２４から延出した延出部３８である。この延出部３８は、谷部２４からその同周上に延出して扁平形状に形成されている。また、延出部３８は、第１の溝部３４の底部及び内側係止凸部３６の内周側端部に連続してそれらの同周上に位置している。   Further, the portion of the male lock portion 32 located on the slit side of the valley portion 24 is an extension portion 38 extending from the valley portion 24. The extending portion 38 extends from the valley portion 24 on the same circumference and is formed in a flat shape. Further, the extending portion 38 is continuously located on the same circumference of the bottom portion of the first groove portion 34 and the inner peripheral side end portion of the inner locking convex portion 36.

雌ロック部４２は、スリットの両側の縁部のうちの他方の縁部から周方向の一部の範囲を占め、雄ロック部３２に対して外側から被せられて雄ロック部３２に重なって係止する部分である。このように、雌ロック部４２は、雄ロック部３２の外周部に係止可能に形成されている。この雌ロック部４２は、その内周側において外側係止凹部４４を形成している。   The female lock portion 42 occupies a partial range in the circumferential direction from the other edge portion of the both side edges of the slit, covers the male lock portion 32 from the outside, and overlaps with the male lock portion 32. It is the part to stop. As described above, the female lock portion 42 is formed so as to be able to be engaged with the outer peripheral portion of the male lock portion 32. The female lock portion 42 forms an outer locking recess 44 on the inner peripheral side thereof.

外側係止凹部４４は、内周側において凹となる（換言すると外周側において凸となる）形状に形成され、内側係止凸部３６の外周部に対して嵌合される部分である。すなわち、外側係止凹部４４は、自身の内部空間内に内側係止凸部３６が配設される形態で、内側係止凸部３６に対して外嵌めされる。この外側係止凹部４４は、周方向他端側における山部２２のスリット側の位置に設けられている。ここでは、外側係止凹部４４は、周方向において、山部２２に対して、本体部２０に形成された第２の溝部２６を挟んで設けられている。   The outer locking recess 44 is formed in a shape that is concave on the inner peripheral side (in other words, convex on the outer peripheral side), and is a portion that is fitted to the outer peripheral portion of the inner locking convex portion 36. That is, the outer locking recess 44 is externally fitted to the inner locking projection 36 in a form in which the inner locking projection 36 is disposed in its own internal space. The outer locking recess 44 is provided at a position on the slit side of the peak portion 22 on the other end side in the circumferential direction. Here, the outer locking concave portion 44 is provided with respect to the mountain portion 22 with the second groove portion 26 formed in the main body portion 20 interposed therebetween in the circumferential direction.

この外側係止凹部４４は、軸方向において山部２２と略同寸法に設定されている。内側係止凸部３６との関係では、外側係止凹部４４は、軸方向において内部空間が内側係止凸部３６より大きく（ここでは僅かに大きく）設定されている。好ましくは、外側係止凹部４４と内側係止凸部３６とは、軸方向においてなるべく隙間なく嵌合可能であるとよい。また、外側係止凹部４４は、周方向において、雄ロック部３２の内側係止凸部３６より大きく設定されている。   The outer locking recess 44 is set to have substantially the same dimensions as the mountain portion 22 in the axial direction. In relation to the inner locking convex portion 36, the outer locking concave portion 44 is set such that the inner space is larger (slightly larger here) than the inner locking convex portion 36 in the axial direction. Preferably, the outer locking recess 44 and the inner locking projection 36 can be fitted with as little gap as possible in the axial direction. Further, the outer locking concave portion 44 is set larger than the inner locking convex portion 36 of the male lock portion 32 in the circumferential direction.

また、外側係止凹部４４は、内周側端部が谷部２４より外周側の位置に設定されている。ここでは、外側係止凹部４４は、内外方向において、谷部２４よりロック付コルゲートチューブ１０の各部の厚さ寸法と略同じ寸法分外周側の位置から外周側に突出している。なお、外側係止凹部４４の外周側端部は、山部２２の外周側端部と略同周上に設定されている。すなわち、外側係止凹部４４は、内側係止凸部３６に嵌合される際に、その内周側端部が第１の溝部３４の底部上及び延出部３８上に配設された状態で、スリットを挟んだ周方向一端側の山部２２に対して外周側端部が略同周上に位置するように構成されている。   Further, the outer locking recess 44 has an inner peripheral side end set at a position on the outer peripheral side with respect to the valley portion 24. Here, the outer locking concave portion 44 protrudes from the valley portion 24 to the outer peripheral side from the position on the outer peripheral side by substantially the same dimension as the thickness dimension of each portion of the corrugated tube 10 with the lock in the inner and outer directions. The outer peripheral side end of the outer locking recess 44 is set substantially on the same circumference as the outer peripheral side end of the peak portion 22. That is, when the outer locking concave portion 44 is fitted to the inner locking convex portion 36, the inner peripheral side end portion is disposed on the bottom portion and the extending portion 38 of the first groove portion 34. Thus, the outer peripheral side end portion is configured to be located substantially on the same circumference with respect to the crest portion 22 on one end side in the circumferential direction across the slit.

また、雌ロック部４２のうち、谷部２４のスリット側に位置する部分は、谷部２４から延出した延出部４８である。この延出部４８は、谷部２４に連続して、谷部２４より外周側で周方向に沿ってスリット側に延出する扁平形状に形成されている。また、延出部４８は、外側係止凹部４４の基端部と連続してその同周上に位置している。   Further, a portion of the female lock portion 42 located on the slit side of the valley portion 24 is an extension portion 48 extending from the valley portion 24. The extending portion 48 is formed in a flat shape extending continuously from the valley portion 24 toward the slit side along the circumferential direction on the outer peripheral side. Further, the extending portion 48 is located on the same circumference continuously with the base end portion of the outer locking recess 44.

また、雌ロック部４２の外側係止凹部４４及び延出部４８のスリット側には、周方向に延出する端部ベラ４５が設けられていてもよい。この端部ベラ４５は、外側係止凹部４４の内周側部分において延出する扁平な形状に形成され、ロック付コルゲートチューブ１０の延在方向（軸方向）に沿って延在している。また、端部ベラ４５のスリット側への延出寸法は、雄ロック部３２の第１の溝部３４内に配設可能な大きさに設定されている。   In addition, an end spatula 45 extending in the circumferential direction may be provided on the outer locking recess 44 of the female lock portion 42 and the slit side of the extension portion 48. The end spatula 45 is formed in a flat shape extending at the inner peripheral side portion of the outer locking recess 44 and extends along the extending direction (axial direction) of the corrugated tube 10 with lock. The extension dimension of the end spatula 45 toward the slit side is set to a size that can be disposed in the first groove 34 of the male lock part 32.

＜ロック付コルゲートチューブの製造方法＞
上記ロック付コルゲートチューブ１０は、例えば、以下のようにして製造される。まず、溶融させた合成樹脂材料を押出成形用の金型を用いて筒状に押し出す。押し出された軟らかい状態の筒状体を一対の金型９０で挟み込み、ブロー成型又はバキューム成型によって一対の金型９０に密着させることにより、凹凸を有する筒状に形成する。そして、得られた凹凸を有する筒状体を周方向一部で軸方向に沿って切り開くことによりスリットを形成する。 <Method of manufacturing corrugated tube with lock>
The corrugated tube 10 with a lock is manufactured as follows, for example. First, the melted synthetic resin material is extruded into a cylindrical shape using an extrusion mold. The extruded cylindrical body is sandwiched between a pair of molds 90, and is brought into close contact with the pair of molds 90 by blow molding or vacuum molding, thereby forming a cylindrical shape having irregularities. And the slit is formed by opening the cylindrical body which has the unevenness | corrugation along the axial direction in a part of circumferential direction.

ここでは、雄ロック部３２の内側係止凸部３６と雌ロック部４２の外側係止凹部４４とが周方向に連結された筒状体に成型され、内側係止凸部３６と外側係止凹部４４との境界部分で該筒状体を切り開いている。すなわち、ロック構造部３０のロック前形態とは、成形後の筒状体が切り開かれた形態である。   Here, the inner locking convex portion 36 of the male locking portion 32 and the outer locking concave portion 44 of the female locking portion 42 are molded into a cylindrical body connected in the circumferential direction, and the inner locking convex portion 36 and the outer locking protrusion 44 are molded. The cylindrical body is cut open at the boundary with the recess 44. That is, the pre-locking form of the lock structure 30 is a form in which the molded cylindrical body is cut open.

＜溝部について＞
第２の溝部２６は、本体部２０のうち、周方向における雌ロック部４２の側方の一箇所のみに設けられ、谷部２４の外周面と面一の底部２７を有すると共に周方向において山部２２を二分して軸方向に沿った一連の溝状に形成された部分である。すなわち、第２の溝部２６は、本体部の山部２２を横切って形成されている。ここでは、第２の溝部２６は、周方向において、本体部２０の他端部に形成されている。換言すると、第２の溝部２６は、雌ロック部４２の外側係止凹部４４及び延在部４８の側方に連続して形成されている。 <About the groove>
The second groove portion 26 is provided only at one location on the side of the female lock portion 42 in the circumferential direction in the main body portion 20, and has a bottom portion 27 that is flush with the outer peripheral surface of the valley portion 24 and has a mountain in the circumferential direction. This is a portion formed by dividing the portion 22 into a series of grooves along the axial direction. That is, the second groove portion 26 is formed across the peak portion 22 of the main body portion. Here, the 2nd groove part 26 is formed in the other end part of the main-body part 20 in the circumferential direction. In other words, the second groove portion 26 is continuously formed on the side of the outer locking recess 44 and the extension portion 48 of the female lock portion 42.

この第２の溝部２６は、雄ロック部３２の第１の溝部３４（その他、ロック構造部３０における凹凸形状部分）とは異なり、ロック形態において他の部分と嵌合しない部分である(図４参照)。なお、第１の溝部３４には、雌ロック部４２の端部ベラ４５を含むスリット側端部が嵌まり込む。   Unlike the first groove portion 34 of the male lock portion 32 (in addition, the uneven portion in the lock structure portion 30), the second groove portion 26 is a portion that does not fit into other portions in the lock configuration (FIG. 4). reference). In addition, the slit side end part including the edge part 45 of the female lock part 42 is fitted in the first groove part 34.

第２の溝部２６は、谷部２４から山部２２の外周部に向けて谷部２４の接線に沿って延在する側壁部２８を有する形状に形成されている（図３の側壁部２８上を通る一点鎖線参照）。この側壁部２８は、ロック付コルゲートチューブ１０の金型成型時に一対の金型９０の接離方向に沿って延在している(図３参照)。そして、第２の溝部２６は、軸方向に直交する断面視において、略Ｖ字状を成している。   The second groove 26 is formed in a shape having a side wall 28 extending along the tangent line of the valley 24 from the valley 24 toward the outer periphery of the peak 22 (on the side wall 28 in FIG. 3). Dash-dot line through The side wall 28 extends along the contact / separation direction of the pair of molds 90 when the corrugated tube 10 with lock is molded (see FIG. 3). And the 2nd groove part 26 has comprised substantially V shape in the cross sectional view orthogonal to an axial direction.

第２の溝部２６の底部２７は、軸方向に沿って線状に延びている。これにより、ロック付コルゲートチューブ１０は、周方向において、第２の溝部２６のうち線状の底部２７に沿って屈曲するように撓む。もっとも、第２の溝部２６の底部２７は、周方向に幅を有する平坦面状に形成されていてもよい。この場合、ロック付コルゲートチューブ１０は、周方向において、幅を有する底部２７が湾曲するように撓む。また、延在部４８が、谷部２４が沿う周面に対して傾斜して角部をなす面に沿って延在し、その角部をなす部分が第２の溝部２６の底部２７を形成してもよい。すなわち、軸方向に直交する断面視において、谷部２４と延在部４８とが折れ線状を成している。これにより、ロック付コルゲートチューブ１０は、折れ部分である底部２７を基点として変形し易くなると考えられる。   The bottom 27 of the second groove 26 extends linearly along the axial direction. Thereby, the corrugated tube 10 with a lock | rock bends so that it may bend along the linear bottom part 27 among the 2nd groove parts 26 in the circumferential direction. But the bottom part 27 of the 2nd groove part 26 may be formed in the flat surface shape which has a width | variety in the circumferential direction. In this case, the corrugated tube 10 with a lock is bent so that the bottom 27 having a width is curved in the circumferential direction. Further, the extending portion 48 is inclined with respect to the circumferential surface along which the valley portion 24 extends and extends along a surface forming a corner portion, and the portion forming the corner portion forms the bottom portion 27 of the second groove portion 26. May be. That is, in the cross-sectional view orthogonal to the axial direction, the valley portion 24 and the extending portion 48 form a polygonal line shape. Thereby, it is thought that the corrugated tube 10 with a lock | rock becomes easy to deform | transform using the bottom part 27 which is a broken part as a base point.

＜ワイヤーハーネスに対する装着＞
ロック付コルゲートチューブ１０をワイヤーハーネス１に対して装着する際には、まず、ワイヤーハーネス１を、スリットを通じてロック付コルゲートチューブ１０の内側に配設する（図３参照）。このとき、ロック構造部３０は、ロック前形態に維持されている。ワイヤーハーネス１がロック付コルゲートチューブ１０内に配設された状態で、ロック構造部３０をロック形態に変形させる（図４参照）。すなわち、ロック付コルゲートチューブ１０を縮径させるようにして弾性変形させつつ、雌ロック部４２を雄ロック部３２に被せる。より具体的には、内側係止凸部３６を外側係止凹部４４の内側に配設する形態で両者を嵌合させると共に、雌ロック部４２のスリット側端部（外側係止凹部４４のスリット側壁部及び端部ベラ４５）を第１の溝部３４内に挿入する。ここで、雌ロック部４２の端部ベラ４５は、第１の溝部３４の底部寄りの位置に配設される。この状態が、ロック構造部３０のロック形態である。 <Mounting to wire harness>
When the corrugated tube 10 with lock is attached to the wire harness 1, first, the wire harness 1 is disposed inside the corrugated tube 10 with lock through a slit (see FIG. 3). At this time, the lock structure 30 is maintained in the pre-lock configuration. In a state where the wire harness 1 is disposed in the corrugated tube 10 with a lock, the lock structure 30 is deformed into a lock form (see FIG. 4). That is, the female lock portion 42 is put on the male lock portion 32 while elastically deforming the corrugated tube 10 with a lock so as to reduce the diameter. More specifically, the inner locking projection 36 is fitted inside the outer locking recess 44 and the two are fitted together, and the slit side end portion of the female locking portion 42 (the slit of the outer locking recess 44) is fitted. Insert the side wall and the end spatula 45) into the first groove 34. Here, the end spatula 45 of the female lock portion 42 is disposed at a position near the bottom of the first groove portion 34. This state is a lock form of the lock structure 30.

ロック形態では、ロック付コルゲートチューブ１０は、ロック前形態に復帰しようとする力により、外側係止凹部４４のスリット側の壁部の内面が内側係止凸部３６の山部２２側を向く外面に係止する。すなわち、ロック前形態に復帰しようとする力とは、拡径しようとして雄ロック部３２と雌ロック部４２とが周方向に離間する力であり、外側係止凹部４４の内面と内側係止凸部３６の外面とが互いに当接するように働く。好ましくは、両壁部は、互いに面接触しているとよい。   In the lock configuration, the corrugated tube with lock 10 has an outer surface in which the inner surface of the wall portion on the slit side of the outer locking recess 44 faces the mountain portion 22 side of the inner locking projection 36 due to the force of returning to the pre-locking configuration. Lock to. That is, the force for returning to the pre-locking form is a force for separating the male lock portion 32 and the female lock portion 42 in the circumferential direction in an attempt to expand the diameter. It works so that the outer surface of the part 36 contacts each other. Preferably, both wall portions are in surface contact with each other.

また、雄ロック部３２は、ロック付コルゲートチューブ１０の拡径しようとする力により、外周側に向けて雌ロック部４２に対して押し付けられている。ここでは、雄ロック部３２の外周部に嵌合する雌ロック部４２の周方向側方に第２の溝部２６が形成され、雄ロック部３２の側方には第２の溝部２６が形成されていない。このため、雄ロック部３２は、本体部２０の一端側部分から雄ロック部３２に亘る部分の剛性により、上述したように外周側へ向けて雌ロック部４２に対して押し付けられる。一方、雌ロック部４２は、係止相手である雄ロック部３２に追従して、第２の溝部２６の底部２７を基点として本体部２０に対して姿勢変更し得る状態にある。   Further, the male lock portion 32 is pressed against the female lock portion 42 toward the outer peripheral side by a force for expanding the diameter of the corrugated tube 10 with a lock. Here, the second groove 26 is formed on the side in the circumferential direction of the female lock 42 that is fitted to the outer periphery of the male lock 32, and the second groove 26 is formed on the side of the male lock 32. Not. For this reason, the male lock part 32 is pressed against the female lock part 42 toward the outer peripheral side as described above by the rigidity of the part extending from the one end side part of the main body part 20 to the male lock part 32. On the other hand, the female lock portion 42 follows the male lock portion 32 that is a locking partner, and is in a state where the posture can be changed with respect to the main body portion 20 with the bottom portion 27 of the second groove portion 26 as a base point.

以上の作用により、ロック構造部３０は、ロック形態に維持されている。   Due to the above action, the lock structure 30 is maintained in a locked configuration.

＜変形時の動作＞
上記ロック付コルゲートチューブ１０において、曲げ又はねじれ等が生じたときの動作について説明する。 <Operation during deformation>
An operation when the corrugated tube 10 with lock is bent or twisted will be described.

まず、ロック付コルゲートチューブ１０が、ロック構造部３０の両側方の部分が近接するように変形する場合について説明する（図５参照）。このような変形時には、雄ロック部３２は、内周側に移動しようとする。一方、雌ロック部４２は、雄ロック部３２に対して係止した状態で、該雄ロック部３２の動作に追従して内周側に移動しようとする。すなわち、第２の溝部２６は、底部２７が外周側に向けて移動し、開くように変形する。そして、雌ロック部４２は、本体部２０の他端側部分に対して、第２の溝部２６の底部２７を基点として相対的に内周側に姿勢変更する。これにより、ロック付コルゲートチューブ１０は、上記変形によっても、雌ロック部４２が雄ロック部３２の外周部に対して嵌合した状態に維持される。   First, a case where the corrugated tube 10 with a lock is deformed so that the portions on both sides of the lock structure 30 are close to each other will be described (see FIG. 5). At the time of such deformation, the male lock portion 32 tends to move to the inner peripheral side. On the other hand, the female lock portion 42 tries to move to the inner peripheral side following the operation of the male lock portion 32 in a state of being locked to the male lock portion 32. That is, the second groove 26 is deformed so that the bottom 27 moves toward the outer peripheral side and opens. Then, the female lock portion 42 changes its posture relative to the inner peripheral side with respect to the other end side portion of the main body portion 20 with the bottom portion 27 of the second groove portion 26 as a base point. Thereby, the corrugated tube 10 with a lock | rock maintains the state which the female locking part 42 fitted with respect to the outer peripheral part of the male locking part 32 also by the said deformation | transformation.

上記実施形態に係るロック付コルゲートチューブ１０によると、周方向に沿って延在する山部２２と谷部２４とが軸方向に交互に連続して設けられた本体部２０が、雌ロック部４２の側方の１箇所にのみ、谷部２４の外周面と面一の底面２７を有するとともに周方向において山部２２を２分する軸方向に沿った一連の第２の溝部２６を有する。そのため、曲げ又は捻れ等によって作用する応力が、本体部２０における第２の溝部２６の底部２７における曲げ変形によって緩和される。すなわち、周方向において雄ロック部３２と雌ロック部４２とが並んだロック前の形態に復帰しようとする力により、雄ロック部３２が外周側に向けて雌ロック部４２に対して押し当てられると共に、周方向側方に第２の溝部２６が形成された雌ロック部４２が雄ロック部３２に対して係止した状態で追従して動く。その結果、雄ロック部３２と雌ロック部４２とのロック状態をより確実に維持し、スリットの口開きをより効果的に抑制することができる。   According to the corrugated tube 10 with a lock according to the above-described embodiment, the main body 20 in which the ridges 22 and the valleys 24 extending along the circumferential direction are provided alternately and continuously in the axial direction is the female lock 42. Only at one side of the groove portion 24, it has a bottom surface 27 that is flush with the outer peripheral surface of the valley portion 24, and a series of second groove portions 26 along the axial direction that divides the peak portion 22 in the circumferential direction. Therefore, the stress acting due to bending or twisting is alleviated by bending deformation at the bottom 27 of the second groove 26 in the main body 20. That is, the male lock portion 32 is pressed against the female lock portion 42 toward the outer peripheral side by a force to return to the form before locking in which the male lock portion 32 and the female lock portion 42 are arranged in the circumferential direction. At the same time, the female locking part 42 in which the second groove part 26 is formed on the side in the circumferential direction follows and moves with the male locking part 32 engaged. As a result, the locked state of the male lock part 32 and the female lock part 42 can be more reliably maintained, and the opening of the slit can be more effectively suppressed.

また、第２の溝部２６が谷部２４から山部２２の外周部に向けて谷部２４の接線に沿って延在する側壁部２８を有する形状に形成されているため、金型成型時に一対の金型９０を該側壁部２８に沿った方向に接離移動させて、成型面のうちの幅方向端部で第２の溝部２８を形成できる。これにより、より小径なものでも第２の溝部２６を形成してスリットの口開きを効果的に抑制することができる。   Further, since the second groove portion 26 is formed in a shape having a side wall portion 28 extending along the tangent line of the valley portion 24 from the valley portion 24 toward the outer peripheral portion of the mountain portion 22, The second groove 28 can be formed at the end in the width direction of the molding surface by moving the mold 90 in the direction along the side wall 28. Thereby, even if it has a smaller diameter, the second groove portion 26 can be formed to effectively suppress the opening of the slit.

また、雄ロック部３２が外周側において凸となる形状に形成された内側係止凸部３６を有し、雌ロック部４２が内周側において凹となる形状に形成され内側係止凸部３６の外周部に対して嵌合される外側係止凹部４４を有しているため、より確実に雄ロック部３２と雌ロック部４２とのロック状態を維持することができる。   Further, the male locking portion 32 has an inner locking convex portion 36 formed in a convex shape on the outer peripheral side, and the female locking portion 42 is formed in a concave shape on the inner peripheral side, and the inner locking convex portion 36. Therefore, the locked state of the male lock part 32 and the female lock part 42 can be maintained more reliably.

これまで、ロック構造部３０が、第１の溝部３４及び内側係止凸部３６を有する雄ロック部３２と、外側係止凹部４４を有する雌ロック部４２とにより構成される例で説明してきたが、この構成に限られるものではない。すなわち、ロック構造部３０は、雌ロック部４２が雄ロック部に外側から被せられて雄ロック部３２に重なって係止する構成であればよく、雄ロック部３２及び雌ロック部４２が互いに対応する種々の凹凸形状に形成されていてよい。   So far, the lock structure portion 30 has been described with an example constituted by the male lock portion 32 having the first groove portion 34 and the inner locking convex portion 36 and the female lock portion 42 having the outer locking concave portion 44. However, it is not limited to this configuration. That is, the lock structure portion 30 may be configured so that the female lock portion 42 is put on the male lock portion from the outside and overlapped with and locked to the male lock portion 32, and the male lock portion 32 and the female lock portion 42 correspond to each other. It may be formed in various uneven shapes.

また、溝部２６は、谷部２４の外周面と面一の底面を有していればよく、側壁部２８を有する断面視略Ｖ字の形状に限られるものではない。   Moreover, the groove part 26 should just have the bottom face flush with the outer peripheral surface of the trough part 24, and is not restricted to the cross-sectional view substantially V shape which has the side wall part 28. FIG.

以上のように、ロック付コルゲートチューブ１０は詳細に説明されたが、上記した説明は、全ての局面において例示であって、この発明がそれに限定されるものではない。また、上述した各種変形例は、相互に矛盾しない限り組み合わせて適用可能である。そして、例示されていない無数の変形例が、この発明の範囲から外れることなく想定され得るものと解される。   As mentioned above, although the corrugated tube 10 with a lock | rock was demonstrated in detail, above-described description is an illustration in all the phases, Comprising: This invention is not limited to it. The various modifications described above can be applied in combination as long as they do not contradict each other. And it is understood that the countless modification which is not illustrated can be assumed without deviating from the scope of the present invention.
