以下、実施形態に係る電線保護部材２０及び保護部材付電線１０について説明する。図１は保護部材付電線１０を示す概略斜視図であり、図２は保護部材付電線１０を示す概略正面図であり、図３は電線保護部材２０を示す概略正面図である。なお、図３では、電線束１２のうち電線保護部材２０によって保護される部分の円形状概形を２点鎖線で示している。   Hereinafter, the electric wire protection member 20 and the electric wire 10 with a protection member according to the embodiment will be described. 1 is a schematic perspective view showing the electric wire 10 with a protection member, FIG. 2 is a schematic front view showing the electric wire 10 with a protection member, and FIG. 3 is a schematic front view showing the electric wire protection member 20. In FIG. 3, a circular outline of a portion of the wire bundle 12 that is protected by the wire protection member 20 is indicated by a two-dot chain line.

保護部材付電線１０は、少なくとも１つの電線としての電線束１２と、電線保護部材２０と、取付部材４０とを備える。   The protective member-attached electric wire 10 includes an electric wire bundle 12 as at least one electric wire, an electric wire protection member 20, and an attachment member 40.

電線束１２は、複数の電線１１が束ねられた構成とされている。ここでは、電線束１２は、その延在方向に対して直交する断面形状が円形状をなすように束ねられている。なお、電線束１２は、本電線保護部材２０によって保護される部分又は電線保護部材２０から外方に延出した部分で、分岐していてもよい。前者の場合、電線保護部材２０の延在方向中間部に電線を引出すための凹部を形成しておき、当該凹部から電線を引出すとよい。   The electric wire bundle 12 has a configuration in which a plurality of electric wires 11 are bundled. Here, the electric wire bundle 12 is bundled so that the cross-sectional shape orthogonal to the extending direction forms a circular shape. The wire bundle 12 may be branched at a portion protected by the wire protection member 20 or a portion extending outward from the wire protection member 20. In the case of the former, it is good to form the recessed part for drawing out an electric wire in the extension direction intermediate part of the electric wire protection member 20, and to draw an electric wire from the said recessed part.

電線束１２に対して、光ファイバケーブル及びウオッシャーチューブ等のチューブ類の少なくとも１つが束ねられていてもよい。また、保護対象は、１本の電線であってもよい。すなわち、本電線保護部材２０による保護対象として、少なくとも１本の電線を含めばよく、これに別の電線以外の線状体が付加されていてもよい。   At least one of tubes such as an optical fiber cable and a washer tube may be bundled with the wire bundle 12. Further, the protection target may be a single electric wire. That is, at least one electric wire may be included as an object to be protected by the electric wire protection member 20, and a linear body other than another electric wire may be added thereto.

本保護部材付電線１０は、車両における所定の配線形態に沿って配設された状態で、コネクタ接続等を介して各種車載電気部品に接続される。これにより、車載電気部品が本保護部材付電線１０を介して相互に電気的に接続される。   The protective member-equipped electric wire 10 is connected to various on-vehicle electrical components through connector connection or the like in a state of being arranged along a predetermined wiring form in the vehicle. Thereby, the vehicle-mounted electrical components are electrically connected to each other via the electric wire 10 with the protective member.

電線保護部材２０は、不織部材がホットプレスされることによりシート状に形成され、その少なくとも一方の主面に、複数の直線状の凸状部２４と複数の直線状の凹状部２６とが交互にストライプ状に形成された構成とされている。   The electric wire protection member 20 is formed in a sheet shape by hot pressing a non-woven member, and a plurality of linear convex portions 24 and a plurality of linear concave portions 26 are formed on at least one main surface thereof. It is configured to be alternately formed in a stripe shape.

ここで、ホットプレスとは、不織部材に対して加熱処理及び不織部材を型に押付けて所定形状に形成する処理を施すことをいう。加熱処理と所定形状への形成処理とは、同時に行われてもよいし、或は、連続的に別々に行われてもよい。例えば、不織部材を圧縮状態で加熱した後、冷却により固まる前に所定の型に押付けて曲げることで、当該曲げ形状に維持できる。この実施形態に係る電線保護部材２０を加工するのに適したホットプレス加工の例については後にさらに詳述する。   Here, the hot press refers to performing a heat treatment on a non-woven member and a process of pressing the non-woven member against a mold to form a predetermined shape. The heat treatment and the forming process into a predetermined shape may be performed simultaneously, or may be performed separately continuously. For example, after heating a non-woven member in a compressed state, the non-woven member can be maintained in the bent shape by being pressed against a predetermined mold and bent before being solidified by cooling. An example of hot pressing suitable for processing the wire protection member 20 according to this embodiment will be described in detail later.

また、加工対象となる不織部材としては、少なくとも一部が溶融し或いは軟らかくなり、その後冷却工程を経て硬くなることが可能なものを用いることができる。このような不織部材として、基本繊維とバインダ（接着樹脂とも呼ばれる）とを含むものを用いることができる。バインダは、基本繊維の融点（例えば、２５０度）よりも低い融点（例えば、１１０度〜１５０度）を有する樹脂である。そして、不織部材を、基本繊維の融点より低く且つバインダの融点よりも高い温度に加熱することにより、バインダが溶融されて基本繊維間にしみ込む。この後、不織部材の温度が低下すると、バインダが凝固する。これにより、不織部材を加熱時の成形状態に維持することができる。   In addition, as the non-woven member to be processed, one that can be at least partially melted or softened and then hardened through a cooling step can be used. As such a non-woven member, a material containing basic fibers and a binder (also called an adhesive resin) can be used. The binder is a resin having a melting point (for example, 110 to 150 degrees) lower than the melting point (for example, 250 degrees) of the basic fiber. Then, by heating the nonwoven member to a temperature lower than the melting point of the basic fiber and higher than the melting point of the binder, the binder is melted and soaks between the basic fibers. Thereafter, when the temperature of the nonwoven member is lowered, the binder is solidified. Thereby, a nonwoven member can be maintained in the shaping | molding state at the time of a heating.

不織部材の基本繊維としては、バインダの融点で繊維状態を保ち得るものであればよく、樹脂繊維の他、ガラス繊維等の各種繊維を用いることができる。また、バインダは、基本繊維の融点より低い融点を有する熱可塑性樹脂繊維を用いることができる。例えば、基本繊維とバインダとの組合せとしては、基本繊維をＰＥＴ（ポリエチレンテレフタレート）の樹脂繊維とし、バインダをＰＥＴとＰＥＩ（ポリエチレンイソフタレート）との共重合樹脂としたものが挙げられる。   As a basic fiber of a nonwoven member, what is necessary is just to be able to maintain a fiber state with melting | fusing point of a binder, and various fibers, such as glass fiber other than a resin fiber, can be used. Moreover, the thermoplastic resin fiber which has melting | fusing point lower than melting | fusing point of a basic fiber can be used for a binder. For example, as a combination of a basic fiber and a binder, there may be mentioned one in which the basic fiber is a resin fiber of PET (polyethylene terephthalate) and the binder is a copolymer resin of PET and PEI (polyethylene isophthalate).

ここでは、電線保護部材２０は、方形シート状に形成されており、電線保護部材２０の両方の主面のそれぞれに、複数の凸状部２４と複数の凹状部２６とが交互にストライプ状に形成されている。複数の凸状部２４と複数の凹状部２６とは、電線保護部材２０の４つの辺のうち対向する一組の辺の方向に沿って延在している。また、複数の凸状部２４と複数の凹状部２６とは、４つの辺のうち対向する他の一組の辺に至る迄形成されている。すなわち、複数の凸状部２４と複数の凹状部２６とは、電線保護部材２０の１つの辺からこれに対向する他の辺に亘って全体的に形成されている。   Here, the electric wire protection member 20 is formed in a rectangular sheet shape, and a plurality of convex portions 24 and a plurality of concave portions 26 are alternately formed in stripes on both main surfaces of the electric wire protection member 20. Is formed. The plurality of convex portions 24 and the plurality of concave portions 26 extend along the direction of a pair of opposing sides of the four sides of the wire protection member 20. Further, the plurality of convex portions 24 and the plurality of concave portions 26 are formed up to another set of opposing sides among the four sides. That is, the plurality of convex portions 24 and the plurality of concave portions 26 are entirely formed from one side of the wire protection member 20 to the other side opposite thereto.

電線保護部材２０の一方の主面には、複数の凸状部２４と複数の凹状部２６とが交互にストライプ状に形成されている。凸状部２４をその延在方向に沿った方向から見ると、湾曲しつつ突出する形状に形成されている。また、凹状部２６をその延在方向に沿って見ると、湾曲しつつ凹む形状に形成されている。このため、電線保護部材２０の一方の主面を、複数の凸状部２４と複数の凹状部２６との延在方向に対して直交する方向から観察すると、凸形状部分と凹形状部分とがサインカーブを描きつつ連続する形状を示す。   On one main surface of the wire protection member 20, a plurality of convex portions 24 and a plurality of concave portions 26 are alternately formed in a stripe shape. When the convex portion 24 is viewed from the direction along the extending direction, the convex portion 24 is formed in a shape protruding while being curved. Further, when the concave portion 26 is viewed along the extending direction, the concave portion 26 is formed in a concave shape while being curved. For this reason, when one main surface of the wire protection member 20 is observed from a direction orthogonal to the extending direction of the plurality of convex portions 24 and the plurality of concave portions 26, the convex portion and the concave portion are formed. Shows a continuous shape while drawing a sine curve.

また、電線保護部材２０の他方の主面には、複数の凸状部２４と複数の凹状部２６とが交互にストライプ状に形成されている。電線保護部材２０の他方の主面に形成された複数の凸状部２４と複数の凹状部２６とは、電線保護部材２０の一方の主面に形成された複数の凸状部２４と複数の凹状部２６と同形状に形成されている。このため、このため、電線保護部材２０の他方の主面を、複数の凸状部２４と複数の凹状部２６との延在方向に対して直交する方向から観察すると、凸形状部分と凹形状部分とがサインカーブを描きつつ連続する形状を示す。   In addition, a plurality of convex portions 24 and a plurality of concave portions 26 are alternately formed in a stripe shape on the other main surface of the wire protection member 20. The plurality of convex portions 24 and the plurality of concave portions 26 formed on the other main surface of the wire protection member 20 are the plurality of convex portions 24 and the plurality of concave portions 26 formed on one main surface of the wire protection member 20. It is formed in the same shape as the concave portion 26. For this reason, when the other main surface of the wire protection member 20 is observed from a direction orthogonal to the extending direction of the plurality of convex portions 24 and the plurality of concave portions 26, the convex portion and the concave shape are observed. The part shows a continuous shape while drawing a sine curve.

また、電線保護部材２０を平面視で観察すると、電線保護部材２０の一方の主面に形成された複数の凸状部２４は、電線保護部材２０の他方の主面に形成された凹状部２６に対応する位置に形成されている。また、電線保護部材２０の一方の主面に形成された複数の凹状部２６は、電線保護部材２０の一方の主面に形成された凸状部２４に対応する位置に形成されている。このため、電線保護部材２０を全体的に観察すると、同じ厚み寸法の板材が連続する波を形成する形状を示す。   Further, when the electric wire protection member 20 is observed in a plan view, the plurality of convex portions 24 formed on one main surface of the electric wire protection member 20 are concave portions 26 formed on the other main surface of the electric wire protection member 20. It is formed in the position corresponding to. In addition, the plurality of concave portions 26 formed on one main surface of the wire protection member 20 are formed at positions corresponding to the convex portions 24 formed on one main surface of the wire protection member 20. For this reason, when the electric wire protection member 20 is observed entirely, the shape which forms the wave which the board | plate material of the same thickness dimension continues is shown.

この電線保護部材２０は、複数の凸状部２４と複数の凹状部２６との延在方向を、電線束１２の延在方向に一致させた状態で、電線束１２に巻付けられている。電線保護部材２０の初期形状は、平面状に延在しており、この電線保護部材２０を電線束１２に巻付ける際には、電線束１２の外形状に応じて丸める必要がある。電線保護部材２０は、複数の凸状部２４と複数の凹状部２６とが交互にストライプ状に形成された構成であるため、電線保護部材２０は、主として複数の凸状部２４と複数の凹状部２６との延在方向と一致する各ラインに沿って徐々に曲ることができる。このため、電線保護部材２０を全体的に電線束１２の形状に応じた形状に丸めやすい（図３において２点鎖線で示す電線保護部材２０参照）。このため、電線保護部材２０を、電線束１２に容易に巻付けることができる。   The wire protection member 20 is wound around the wire bundle 12 in a state where the extending directions of the plurality of convex portions 24 and the plurality of concave portions 26 coincide with the extending direction of the wire bundle 12. The initial shape of the wire protection member 20 extends in a planar shape, and when the wire protection member 20 is wound around the wire bundle 12, it is necessary to round the wire protection member 20 according to the outer shape of the wire bundle 12. Since the wire protection member 20 has a configuration in which a plurality of convex portions 24 and a plurality of concave portions 26 are alternately formed in a stripe shape, the wire protection member 20 is mainly composed of a plurality of convex portions 24 and a plurality of concave shapes. It can bend gradually along each line that coincides with the direction of extension with the portion 26. For this reason, it is easy to round the electric wire protection member 20 into the shape according to the shape of the electric wire bundle 12 as a whole (refer to the electric wire protection member 20 shown by a two-dot chain line in FIG. 3). For this reason, the electric wire protection member 20 can be easily wound around the electric wire bundle 12.

なお、好ましくは、電線保護部材２０の内周部が電線束１２の外周部に接するように、電線保護部材２０が電線束１２に巻付けられる。また、好ましくは、電線保護部材２０の周方向の両端部が重なるように、電線保護部材２０が電線束１２に巻付けられる。もっとも、これらは必須ではなく、例えば、電線保護部材２０の周方向の両端部の間に隙間が空いていてもよい。   Preferably, the wire protection member 20 is wound around the wire bundle 12 so that the inner periphery of the wire protection member 20 contacts the outer periphery of the wire bundle 12. Preferably, the wire protection member 20 is wound around the wire bundle 12 so that both ends in the circumferential direction of the wire protection member 20 overlap. But these are not essential, for example, the clearance gap may be vacant between the both ends of the circumferential direction of the electric wire protection member 20. FIG.

取付部材４０は、粘着テープ又は結束バンド等により構成された部材であり、電線束１２に巻付けられた電線保護部材２０の周囲に巻付けられることで、電線保護部材２０が電線束１２に巻付けられて取付られた状態を維持している。ここでは、電線保護部材２０の延在方向において間隔をあけて複数の取付部材４０が取付けられている。取付部材４０の数は、電線保護部材２０の長さ寸法に応じて変えるとよい。一般的には、電線保護部材２０の両端部に近い２箇所に取付部材４０を巻付けることが好ましく、電線保護部材２０の長さ寸法が長くなれば、その長さ寸法に応じて電線保護部材２０の長手方向中間部にも１つ又は複数の取付部材４０を巻付けることが好ましい。   The attachment member 40 is a member formed of an adhesive tape, a binding band, or the like, and the wire protection member 20 is wound around the wire bundle 12 by being wound around the wire protection member 20 wound around the wire bundle 12. The attached state is maintained. Here, a plurality of attachment members 40 are attached at intervals in the extending direction of the wire protection member 20. The number of attachment members 40 may be changed according to the length dimension of the wire protection member 20. In general, it is preferable to wrap the attachment member 40 at two locations close to both ends of the wire protection member 20, and if the length dimension of the wire protection member 20 becomes longer, the wire protection member according to the length dimension. It is preferable to wind one or a plurality of attachment members 40 around the 20 middle portion in the longitudinal direction.

この実施形態では、電線保護部材２０が電線束１２に取付けられた状態で、一方の主面側の複数の凸状部２４及び複数の凹状部２６は、電線保護部材２０の外周側に設けられている。   In this embodiment, in a state where the wire protection member 20 is attached to the wire bundle 12, the plurality of convex portions 24 and the plurality of concave portions 26 on one main surface side are provided on the outer peripheral side of the wire protection member 20. ing.

上記電線保護部材２０の一製造例について説明する。   A manufacturing example of the wire protection member 20 will be described.

まず、図４に示すように、長尺状シート状の不織部材３０Ｂが丸められた状態で供給される。そして、この不織部材３０Ｂを所定長に切断し（図４の点線参照）、方形シート状の不織部材３０を得る。   First, as shown in FIG. 4, the long sheet-like non-woven member 30B is supplied in a rolled state. And this nonwoven member 30B is cut | disconnected by predetermined length (refer the dotted line of FIG. 4), and the rectangular sheet-like nonwoven member 30 is obtained.

下型５２は、熱伝導性に優れた金属等により形成された長尺部材であり、その一主面（上面）に下型面５３が形成されている。下型面５３は、電線保護部材２０の一方主面を形作るための部分であり、凸部と凹部とが交互に連続する波状の面を形成している。   The lower mold 52 is a long member formed of a metal or the like having excellent thermal conductivity, and a lower mold surface 53 is formed on one main surface (upper surface) thereof. The lower mold surface 53 is a portion for forming one main surface of the electric wire protection member 20, and forms a wavy surface in which convex portions and concave portions are alternately continued.

上型６２は、熱伝導性に優れた金属等により形成された長尺部材であり、その一主面（下面）に上型面６３が形成されている。上型面６３は、電線保護部材２０の他方主面を形作るための部分であり、凸部と凹部とが交互に連続する波状の面を形成している。   The upper mold 62 is a long member formed of a metal or the like having excellent thermal conductivity, and an upper mold surface 63 is formed on one main surface (lower surface) thereof. The upper mold surface 63 is a portion for forming the other main surface of the wire protection member 20, and forms a wave-like surface in which convex portions and concave portions are alternately continued.

そして、この上型面６３と下型面５３とが近接対向配置されることにより、それらの間で、電線保護部材２０を形成可能なスペースが形成される。なお、下型５２及び上型６２には、ヒーター等の加熱部５４、６４が設けられている。   The upper mold surface 63 and the lower mold surface 53 are arranged close to each other so that a space in which the wire protection member 20 can be formed is formed between them. The lower mold 52 and the upper mold 62 are provided with heating parts 54 and 64 such as a heater.

上記ホットプレス型５０を用いてホットプレス加工を行う。   Hot pressing is performed using the hot pressing die 50.

すなわち、シート状の不織部材３０を下型面５３と上型面６３との間に配設する。なお、不織部材３０は、２つのシート状の不織部材を重ね合せたものであってもよい。２つのシート状の不織部材として、バインダの混合割合等が異なるものを用いることで、電線保護部材２０の一方の主面と他方の主面とを異なる硬さに形成することができる。また、下型５２と上型６２との加熱温度を異なるように設定してもよい。これによっても、電線保護部材２０の一方の主面と他方の主面とを異なる硬さに形成することができる。   That is, the sheet-like non-woven member 30 is disposed between the lower mold surface 53 and the upper mold surface 63. The nonwoven member 30 may be a laminate of two sheet-like nonwoven members. By using the two sheet-like non-woven members having different binder mixing ratios, the one main surface and the other main surface of the wire protection member 20 can be formed to have different hardnesses. Further, the heating temperatures of the lower mold 52 and the upper mold 62 may be set differently. Also by this, one main surface and the other main surface of the electric wire protection member 20 can be formed in different hardness.

そして、下型５２と上型６２とを接近移動させて、下型面５３と上型面６３との間で不織部材３０を挟込み、当該不織部材３０を加圧及び加熱する。これにより、不織部材３０中のバインダが溶融する。   Then, the lower mold 52 and the upper mold 62 are moved close to each other to sandwich the nonwoven member 30 between the lower mold surface 53 and the upper mold surface 63, and the nonwoven member 30 is pressurized and heated. Thereby, the binder in the non-woven member 30 is melted.

この後、不織部材３０が冷却されると、上記下型５２及び上型６２間で、不織部材３０が下型面５３及び上型面６３の形状に応じた形状で硬化し、電線保護部材２０が形成される。   Thereafter, when the non-woven member 30 is cooled, the non-woven member 30 is cured between the lower mold 52 and the upper mold 62 in a shape corresponding to the shapes of the lower mold surface 53 and the upper mold surface 63, thereby protecting the electric wire. Member 20 is formed.

この後、電線保護部材２０がホットプレス型５０から取出される。   Thereafter, the wire protection member 20 is taken out from the hot press mold 50.

なお、図６に示すように、長尺シート状の不織部材を連続的にホットプレス加工して、複数の凸状部２４と複数の凹状部２６とが多数交互に形成された元部材２０Ｂを準備し、これを保護対象となる電線束１２の外径寸法等に応じて切断して（図６の点線参照）、電線保護部材２０を製造するようにしてもよい。これにより、複数の電線保護部材２０を効率よく製造できる。また、各種外径寸法の電線束１２にも容易に対応できるというメリットもある。   As shown in FIG. 6, the original member 20 </ b> B in which a plurality of convex portions 24 and a plurality of concave portions 26 are alternately formed by continuously hot-pressing a long sheet-like nonwoven member. May be cut according to the outer diameter of the wire bundle 12 to be protected (see the dotted line in FIG. 6) to manufacture the wire protection member 20. Thereby, the some electric wire protection member 20 can be manufactured efficiently. In addition, there is an advantage that the wire bundle 12 having various outer diameters can be easily handled.

このように形成された電線保護部材２０が上記したように電線束１２に取付られる。   The electric wire protection member 20 formed in this way is attached to the electric wire bundle 12 as described above.

以上のように構成された保護部材付電線１０及び電線保護部材２０によると、電線保護部材２０は、複数の凸状部２４と複数の凹状部２６との延在方向に沿った各ラインで容易に曲ることができる。このため、複数の凸状部２４と複数の凹状部２６との延在方向を少なくとも１本の電線（１本の電線又は電線束１２）の延在方向に一致させた状態で、電線保護部材２０を少なくとも１本の電線に容易に巻付けることができる。これにより、不織部材３０をホットプレス加工した電線保護部材２０を、少なくとも１本の電線に容易に巻付けることができる。   According to the protective member-equipped electric wire 10 and the electric wire protection member 20 configured as described above, the electric wire protection member 20 is easy in each line along the extending direction of the plurality of convex portions 24 and the plurality of concave portions 26. Can bend to. For this reason, in the state which made the extension direction of the some convex part 24 and the some concave part 26 correspond to the extension direction of at least 1 electric wire (one electric wire or electric wire bundle 12), it is an electric wire protection member. 20 can be easily wound around at least one electric wire. Thereby, the electric wire protection member 20 which hot-pressed the nonwoven member 30 can be easily wound around at least one electric wire.

なお、電線保護部材２０自体は、不織部材３０がホットプレスされたものであるため、ある程度硬い。このため、電線の保護性能、経路規制機能に優れる。電線保護部材２０の硬さは、ホットプレス加工時の温度、不織部材の圧縮度合、不織部材におけるバインダの混合割合等を調整することによって、調整することができる。電線保護部材２０を硬く形成すれば、電線の保護性能及び経路形状維持機能に優れる。また、電線保護部材２０をなるべく柔軟にすれば、防音性（電線保護部材２０とその周辺部材との接触による音の発生）に優れる。電線保護部材２０の硬さは、それが配設される場所において要求される保護性能、経路維持性能、防音性等に応じて調整される。   Note that the wire protection member 20 itself is hard to some extent because the nonwoven member 30 is hot-pressed. For this reason, it is excellent in the protection performance of an electric wire and a path | route control function. The hardness of the electric wire protection member 20 can be adjusted by adjusting the temperature at the time of hot pressing, the degree of compression of the nonwoven member, the mixing ratio of the binder in the nonwoven member, and the like. If the wire protection member 20 is formed hard, the wire protection performance and the path shape maintaining function are excellent. Moreover, if the electric wire protection member 20 is made as flexible as possible, it is excellent in soundproofing (generation of sound due to contact between the electric wire protection member 20 and its peripheral members). The hardness of the electric wire protection member 20 is adjusted according to the protection performance, path maintenance performance, soundproofness, etc. required at the place where it is disposed.

また、不織部材を電線束に巻付けた後に、ホットプレス加工を行う構成では、不織部材の巻付工程及び電線束であるワイヤーハーネスの製造場所でのホットプレス工程が必要であったが、本電線保護部材２０によると、ホットプレス加工は、ワイヤーハーネスの製造場所以外で行うことができ、ワイヤーハーネスの製造場所では、電線保護部材２０の巻付及び取付部材４０の巻付を行えばよいため、その取付及び保護部材付電線１０の製造が容易となる。   Further, in the configuration in which hot pressing is performed after the non-woven member is wound around the electric wire bundle, the non-woven member winding step and the hot pressing step at the production site of the wire harness that is the electric wire bundle are required. According to the electric wire protection member 20, the hot pressing can be performed at a place other than the production site of the wire harness, and if the winding of the electric wire protection member 20 and the attachment member 40 are wound at the production location of the wire harness. Since it is good, the attachment and manufacture of the electric wire 10 with a protection member become easy.

また、電線保護部材２０の両側部の重ね合せ量を調整することにより、電線又は電線束１２の外径寸法にあまり依存せず、電線保護部材２０を電線又は電線束１２に取付けることができ、汎用性に優れる。   In addition, by adjusting the amount of overlap of both sides of the wire protection member 20, the wire protection member 20 can be attached to the wire or the wire bundle 12 without much depending on the outer diameter of the wire or the wire bundle 12. Excellent versatility.

また、複数の凸状部２４と複数の凹状部２６とが、電線保護部材２０の外周側に設けられているため、電線保護部材２０の見かけの厚み寸法を大きく形成でき、耐摩耗性を向上させることができる。すなわち、電線保護部材２０が周辺部材に接触して摩耗したとしても、周辺部材が電線に接触するためには、複数の凸状部２４の最も突出した部分から内面側に至る迄電線保護部材２０が摩耗する必要がある。このため、電線保護部材２０が摩耗したとしても、周辺部材は内部の電線には達し難く、耐摩耗性を向上させることができる。   In addition, since the plurality of convex portions 24 and the plurality of concave portions 26 are provided on the outer peripheral side of the wire protection member 20, the apparent thickness dimension of the wire protection member 20 can be formed large, and the wear resistance is improved. Can be made. That is, even if the wire protection member 20 comes into contact with the peripheral member and wears, in order for the peripheral member to contact the electric wire, the wire protection member 20 extends from the most protruding portion of the plurality of convex portions 24 to the inner surface side. Need to wear. For this reason, even if the electric wire protection member 20 is worn, the peripheral member is difficult to reach the internal electric wire, and the wear resistance can be improved.

また、電線保護部材２０が周辺部材に接触したとしても、凸状部２４のクッション作用等によって、大きな音を発生し難いようにすることができる。   Moreover, even if the wire protection member 20 comes into contact with the peripheral member, it is possible to prevent a loud sound from being generated due to the cushioning action of the convex portion 24 or the like.

また、電線保護部材２０の両主面において、複数の凸状部２４と複数の凹状部２６とが、互いに対応する位置に形成されている。このため、電線保護部材２０は、複数の凸状部２４と複数の凹状部２６との延在方向に沿った各ラインで容易に曲ることができる。このため、電線保護部材２０を、少なくとも１本の電線に対してより容易に取付けることができる。   Further, on both main surfaces of the wire protection member 20, a plurality of convex portions 24 and a plurality of concave portions 26 are formed at positions corresponding to each other. For this reason, the electric wire protection member 20 can be easily bent at each line along the extending direction of the plurality of convex portions 24 and the plurality of concave portions 26. For this reason, the electric wire protection member 20 can be more easily attached to at least one electric wire.

なお、電線保護部材２０の両主面において、複数の凸状部２４と複数の凹状部２６とが、互いに対応する位置に形成されていることは必須ではない。例えば、図７に示す電線保護部材１２０では、一方主面側の複数の凸状部１２４と、他方主面側の複数の複数の凹状部１２６とは互いに異なる位置に形成されている。この場合であっても、電線保護部材１２０は、複数の凸状部１２４と複数の凹状部１２６との延在方向に沿ったラインで容易に曲ることができる。このように、電線保護部材１２０の両面において、複数の凸状部１２４と複数の凹状部１２６が対応する位置関係に配設される必要が無いため、ホットプレス加工時において、下型５２と上型６２とを正確に位置合せする必要が無く、ホットプレス加工が容易となる。   In addition, it is not essential that the plurality of convex portions 24 and the plurality of concave portions 26 are formed at positions corresponding to each other on both main surfaces of the wire protection member 20. For example, in the wire protection member 120 shown in FIG. 7, the plurality of convex portions 124 on one main surface side and the plurality of concave portions 126 on the other main surface side are formed at different positions. Even in this case, the wire protection member 120 can be easily bent along a line along the extending direction of the plurality of convex portions 124 and the plurality of concave portions 126. Thus, since it is not necessary to arrange the plurality of convex portions 124 and the plurality of concave portions 126 in the corresponding positional relationship on both surfaces of the wire protection member 120, the lower mold 52 and the upper There is no need to accurately align the mold 62 and hot pressing is facilitated.

また、電線保護部材２０の両面に複数の凸状部２４と複数の凹状部２６とが形成されていることは必須ではない。   Moreover, it is not essential that the plurality of convex portions 24 and the plurality of concave portions 26 are formed on both surfaces of the wire protection member 20.

例えば、図８に示す電線保護部材２２０では、その一方主面のみに複数の凸状部２２４と複数の凹状部２２６とが交互にストライプ状に形成され、他方主面は平面に形成されている。この場合でも、電線保護部材２２０は、複数の凸状部２２４と複数の凹状部２２６との延在方向に沿ったラインで容易に曲ることができる。   For example, in the wire protection member 220 shown in FIG. 8, a plurality of convex portions 224 and a plurality of concave portions 226 are alternately formed in a stripe shape only on one main surface, and the other main surface is formed in a plane. . Even in this case, the wire protection member 220 can be easily bent along a line along the extending direction of the plurality of convex portions 224 and the plurality of concave portions 226.

また、凸状部２４と凹状部２６は、カーブを描く凸形状又は凹形状である必要は無い。   Further, the convex portion 24 and the concave portion 26 do not need to have a convex shape or a concave shape that draws a curve.

例えば、図９に示す電線保護部材３２０の両面のそれぞれには、横向きにした三角柱状の複数の凸状部３２４と三角溝状の複数の凹状部３２６とが交互にストライプ状に形成されている。この場合でも、電線保護部材２２０は、複数の凸状部３２４と複数の凹状部３２６との延在方向に沿ったラインで容易に曲ることができる。   For example, a plurality of triangular prism-like convex portions 324 and a plurality of triangular groove-like concave portions 326 are alternately formed in stripes on both surfaces of the wire protection member 320 shown in FIG. . Even in this case, the wire protection member 220 can be easily bent along a line along the extending direction of the plurality of convex portions 324 and the plurality of concave portions 326.

その他、凸状部は横向きにした四角柱状等であってもよく、また、凹状部は、四角溝状であってもよい。   In addition, the convex portion may be a square columnar shape or the like that is turned sideways, and the concave portion may be a square groove shape.

なお、上記実施形態及び各変形例で説明した各構成は、相互に矛盾しない限り適宜組合わせることができる。例えば、横向きにした三角柱状の複数の凸状部と三角溝状の複数の凹状部とが、電線保護部材の一方の主面のみに形成されていてもよい。   In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts. For example, a plurality of triangular prism-shaped convex portions and a plurality of triangular groove-shaped concave portions that are horizontally oriented may be formed only on one main surface of the wire protection member.

以上のようにこの発明は詳細に説明されたが、上記した説明は、すべての局面において、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。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 described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
