Description

電線群保護テープWire group protection tape
　本発明は、電線群を直接螺巻して電線群保護チューブと同様に保護機能を備えた電線群保護テープに関する。 The present invention relates to an electric wire group protection tape having a protective function similar to an electric wire group protection tube by directly winding an electric wire group.
　従来、この種の電線群保護テープとして、特許文献１、特許文献２に記載されるものが既に知られている。 Conventionally, what is described in patent document 1 and patent document 2 is already known as this kind of electric wire group protection tape.
　特許文献１に開示されたワイヤハーネス結束用テープ材は、幅方向の一側に凹凸部を形成するとともに、他の一側に平坦部を設け、上記平坦部を重ね代として螺旋状に電線群Ｗの外周に巻きつけ、ハーフラップ巻きして結束する（段落００２６、００２８、図３等）ものである。 The wire harness binding tape material disclosed in Patent Document 1 forms a concavo-convex portion on one side in the width direction, and provides a flat portion on the other side, and the wire group spirally using the flat portion as an overlap allowance.

　しかしながら、特許文献１に開示されたワイヤーハーネス結束用テープ材にあっては、通常のテープ同様に紙巻に巻き付けする状態にした際に、上下のテープ層が内部に形成された空間により厚みが出てきてしまい、ハーネスへ巻き付ける際の作業性が悪化するとともに、屈曲部等に全く使用できないという問題があった。 However, in the wire harness binding tape material disclosed in Patent Document 1, when the tape is wound around a paper roll like a normal tape, the thickness is increased by the space in which the upper and lower tape layers are formed. As a result, workability at the time of winding around the harness deteriorates, and there is a problem that it cannot be used at all at the bent portion.
　また、特許文献２に開示されたワイヤハーネス結束用テープ材にあっては、テープ材と粘着剤からなる構成を有するため、電線群に巻き付けた際も曲げ易いというメリットはある反面、外装材としての電線保護機能が弱いというという問題があった。 In addition, the wire harness binding tape material disclosed in Patent Document 2 has a configuration consisting of a tape material and an adhesive, and therefore has an advantage of being easily bent when wound around an electric wire group, but as an exterior material. There was a problem that the electric wire protection function was weak.

An object of the present invention is to provide an electric wire group protection tape that has a piercing property and a vibration isolation property and can maintain the flexibility of the electric wire group.
　本発明に係る電線群保護テープは、上記目的達成のため、テープ幅方向に間隔を開けて同一面状に配置され、電線群を螺巻できるよう可撓性を有する２つまたは３つの帯状外装材と、前記帯状外装材よりも少なくとも２倍以上の厚さを有し底面部を前記帯状外装材の底面部と面一となるように一致させて前記帯状外装材間に位置され両側の前記帯状外装材と側面部同士を接着された１つまたは２つの帯状クッション材と、前記電線群を螺巻できるよう可撓性を有し、前記帯状クッション材の上面部に接着状態に載置されたクッション材保護用帯状外装材と、前記帯状クッション材が圧縮されない状態に、前記帯状外装材および前記クッション材保護用帯状外装材の上面部に接着されたカバーフィルムと、少なくとも前記帯状外装材の下面に形成された粘着層とを備えた構成である。 In order to achieve the above object, the electric wire group protection tape according to the present invention is arranged on the same plane at intervals in the tape width direction, and has two or three strip-shaped exteriors having flexibility so that the electric wire group can be screwed. And at least two times as thick as the strip-shaped exterior material, and the bottom surface portion is aligned with the bottom surface portion of the strip-shaped exterior material so as to be flush with the strip-shaped exterior material. One or two belt-like cushion materials in which the belt-shaped exterior material and the side surface portions are bonded to each other, and the flexible wire so that the wire group can be screwed, are placed on the upper surface portion of the belt-shaped cushion material in an adhesive state. A belt-shaped exterior material for protecting the cushion material, a cover film bonded to the upper surface of the belt-shaped exterior material and the belt-shaped exterior material for protecting the cushion material in a state where the belt-shaped cushion material is not compressed, and at least the belt-shaped exterior material. On the bottom A configuration in which a made cohesive layer.
　この構成により、本発明に係る電線群保護テープによれば、電線群に螺巻することで、電線群の外周面に、圧縮されていない状態の帯状クッション材を下地とする振動を遮断する機能を有する突条外装帯と、第１，第２の帯状外装材が重ね巻きされた耐突き刺し性を有し、かつ電線群を屈曲し易くさせる平坦形状外装帯とが螺旋状に巻かれた外装構造を形成でき、既存の電線群保護チューブと同様の電線保護効果を得ることができる。 With this configuration, according to the electric wire group protection tape according to the present invention, the function of blocking the vibration with the band-shaped cushion material in an uncompressed state on the outer peripheral surface of the electric wire group by being wound around the electric wire group And a flat-shaped armor belt having a piercing resistance in which the first and second belt-shaped armor members are wound in layers and making the electric wire group easy to be bent is spirally wound. A structure can be formed and the same electric wire protection effect as the existing electric wire group protection tube can be acquired.
　また、本発明に係る電線群保護テープによれば、電線群に既に巻かれた部分については上記突条外装帯が出現しているため、該突条外装帯に重ならないようオーバーラップ巻きを続けていくことで、電線群にオーバーラップ幅を一定に保って肉厚が大きくなることを抑制されたオーバーラップ巻きが容易に行える。 Further, according to the wire group protection tape according to the present invention, since the above-mentioned strip outer band has appeared for the portion already wound around the electric wire group, the overlap winding is continued so as not to overlap the strip outer band. By doing so, it is possible to easily perform overlap winding while keeping the overlap width constant in the electric wire group and suppressing an increase in thickness.
　また、本発明に係る電線群保護テープは、前記帯状クッション材は、両側側面部の前記第１，第２の帯状外装材よりも高い部分が、断面台形であり、前記クッション材保護用帯状外装材は、前記帯状クッション材の上面部と同じ幅を有し、前記帯状クッション材の上面部に接着されている構成としてもよい。 Further, in the wire group protection tape according to the present invention, the band-shaped cushion material has a trapezoidal cross section in a portion higher than the first and second band-shaped exterior materials on both side surfaces, and the band-shaped exterior for cushion material protection The material may have the same width as the upper surface portion of the belt-shaped cushion material and may be bonded to the upper surface portion of the belt-shaped cushion material.

The cover film may be bonded to the upper surface portion of the material and separated from the side surface portion of the belt-shaped cushion material.
　この構成により、本発明に係る電線群保護テープによれば、電線群への螺巻後に突条外装帯がテープ面に垂直な方向から押されることでクッション材保護用帯状外装材が帯状外装材に対してオーバーラップ状態となり、この状態での部品のエッジやバリ等の上記方向からの侵入に対して電線を強固に保護できる。 With this configuration, according to the wire group protection tape according to the present invention, the belt-shaped exterior material for protecting the cushioning material is formed by pressing the protrusion exterior strip from the direction perpendicular to the tape surface after being wound around the wire group. In this state, the electric wire can be strongly protected against the intrusion from the above-mentioned direction such as the edge of the component and the burr.

　次に、本発明に係る一実施の形態について図面を参照して説明する。 Next, an embodiment according to the present invention will be described with reference to the drawings.
　（第１の実施の形態） (First embodiment)
　まず、図１～図４を参照して電線群保護テープの構成を説明する。
　図１に示すように、本実施の形態に係る電線群保護テープ１は、第１の帯状外装材１０と、第２の帯状外装材１１と、帯状クッション材１２と、クッション材保護用帯状外装材１３と、カバーフィルム１４と、粘着層１５，１６と、を備える。カバーフィルム１４は、接着により、第１の帯状外装材１０と、第２の帯状外装材１１と、帯状クッション材１２と、クッション材保護用帯状外装材１３と、を一体に纏めている。 First, the configuration of the wire group protection tape will be described with reference to FIGS.
As shown in FIG. 1, the wire group protection tape 1 according to the present embodiment includes a first strip-shaped exterior material 10, a second strip-shaped exterior material 11, a strip-shaped cushion material 12, and a strip-shaped exterior for cushioning material protection. A material 13, a cover film 14, and adhesive layers 15 and 16 are provided. The cover film 14 integrally bundles the first strip-shaped exterior member 10, the second strip-shaped exterior member 11, the strip-shaped cushion member 12, and the cushion-shaped protective strip-shaped exterior member 13 by bonding.
　図３に示すように、電線群保護テープ１は、電線群Ｗｇの要保護領域に対し、オーバーラップ幅を有して肉厚が大きくなることを抑制されたオーバーラップ巻きされる。電線群Ｗｇの要保護領域は、例えば軸方向長さを例えば１００～５００ｍｍとされる。電線群Ｗｇは、自動車に搭載される種々の電気回路、電気系統等の間を電気的に接続する複数本の電線である。 As shown in FIG. 3, the wire group protection tape 1 is overlap-wrapped with an overlap width and suppressed thickness increase with respect to the protection area of the wire group Wg. The required protection area of the wire group Wg has an axial length of, for example, 100 to 500 mm. The electric wire group Wg is a plurality of electric wires that electrically connect various electric circuits, electric systems, and the like mounted on the automobile.
　電線群保護テープ１は、テープ幅を例えば１９～３０ｍｍとされる。第１，第２の帯状外装材１０，１１およびクッション材保護用帯状外装材１３は、例えばポリプロピレン（Ｐ．Ｐ）、あるいはポリエチレン（Ｐ．Ｅ）等の合成樹脂により帯板状に成形され耐突き刺し性および巻き付け性を有するように厚さを例えば、０．２～１．０ｍｍとされ、幅をテープ幅の例えば約三分の1の６～１０ｍｍとされる。帯状クッション材１２は、ウレタン、スポンジ等の弾性材料よりなり、テープ幅マイナス第１，第２の帯状外装材１０，１１の幅とされる。カバーフィルム１４は、例えば塩化ビニル（PVC）等の樹脂フィルムよりなり、耐引き裂き性および屈曲性を有するように厚さを例えば０．０５～０．１ｍｍとされ、好ましくは０．０７ｍｍとされる。 The wire group protection tape 1 has a tape width of 19 to 30 mm, for example. The first and second strip-shaped exterior materials 10 and 11 and the cushion-shaped protective strip-shaped exterior material 13 are formed into a strip shape by using a synthetic resin such as polypropylene (PP) or polyethylene (PE), for example. The thickness is set to, for example, 0.2 to 1.0 mm so as to have a piercing property and a winding property, and the width is set to, for example, 6 to 10 mm, which is about one third of the tape width. The belt-like cushion material 12 is made of an elastic material such as urethane or sponge and has a tape width minus the width of the first and second belt-like exterior materials 10 and 11. The cover film 14 is made of a resin film such as vinyl chloride (PVC), and has a thickness of, for example, 0.05 to 0.1 mm and preferably 0.07 mm so as to have tear resistance and flexibility. .
　帯状クッション材１２は、第１，第２の帯状外装材１０，１１間に位置され、底面部を第１，第２の帯状外装材１０，１１の底面部と面一となるように一致させて、両側の帯状外装材１０，１１とは側面部同士を接着されている。 The belt-like cushion material 12 is positioned between the first and second belt-like exterior materials 10 and 11, and the bottom surface is made to be flush with the bottom surfaces of the first and second belt-like exterior materials 10 and 11. The side portions are bonded to the strip-shaped exterior materials 10 and 11 on both sides.
　クッション材保護用帯状外装材１３は、帯状クッション材１２の上面部に接着により載置されている。 The belt-shaped exterior material 13 for protecting the cushion material is placed on the upper surface of the belt-shaped cushion material 12 by adhesion.
　カバーフィルム１４は、帯状クッション材１２が圧縮されない状態に、第１，第２の帯状外装材１０，１１およびクッション材保護用帯状外装材１３の上面部に接着されている。また、カバーフィルム１４は、帯状クッション材１２の斜面部１７１，１７２とは、それぞれ接着がなされないまま密着状態に取り付けられている。これにより、カバーフィルム１４は、例えば、後述する製品としての紙管への巻き付け時（図２参照）等、帯状クッション材１２が圧縮された状態において、該帯状クッション材１２の斜面部から離間してしわ部を形成する。 The cover film 14 is bonded to the upper surface portions of the first and second strip-shaped exterior materials 10 and 11 and the cushion-shaped protective strip-shaped exterior material 13 in a state where the strip-shaped cushion material 12 is not compressed. Further, the cover film 14 is attached to the slope portions 171 and 172 of the belt-like cushion material 12 in a close contact state without being bonded to each other. Thereby, the cover film 14 is separated from the inclined surface portion of the belt-like cushion material 12 in a state where the belt-like cushion material 12 is compressed, for example, when wrapped around a paper tube as a product to be described later (see FIG. 2). Form wrinkles.
　粘着層１５，１６は、第１，第２の帯状外装材１０，１１の下面にそれぞれ形成されている。なお、粘着層は、第１，第２の帯状外装材１０，１１と帯状クッション材１２の下面に一体に形成されていてもよい。 The adhesive layers 15 and 16 are formed on the lower surfaces of the first and second strip-shaped exterior materials 10 and 11, respectively. The adhesive layer may be integrally formed on the lower surfaces of the first and second strip-shaped exterior materials 10 and 11 and the strip-shaped cushion material 12.
　帯状クッション材１２は、両側側面部の第１，第２の帯状外装材１０，１１よりも高い部分が、断面台形である。クッション材保護用帯状外装材１３は、帯状クッション材１２の上面部と同じ幅を有し、帯状クッション材１２の上面部に接着されている。 The belt-like cushion material 12 has a trapezoidal cross section at a portion higher than the first and second belt-like exterior materials 10 and 11 on both side surfaces. The belt-shaped exterior material 13 for protecting the cushion material has the same width as the upper surface portion of the belt-shaped cushion material 12 and is bonded to the upper surface portion of the belt-shaped cushion material 12.
　電線保護テープ１は、製品（テープ材）としては、例えば円筒形の紙管に巻き付けた巻付体で提供される。 The electric wire protection tape 1 is provided as a product (tape material), for example, a wound body wound around a cylindrical paper tube.
　図２は、本実施の形態に係る電線群保護テープの巻付体における要部構造を模式的に示す断面図である。電線群保護テープ１は、巻付体では紙管２０に多重に巻かれているが、図２では特に、三重に巻かれた状態での断面構造を示している。 FIG. 2 is a cross-sectional view schematically showing the main structure of the wound body of the wire group protection tape according to the present embodiment. The wire group protection tape 1 is wound around the paper tube 20 in a wrapping body, but FIG. 2 shows a cross-sectional structure in a state of being wound in triplicate.
　図２に示すように、紙管２０に巻かれた電線群保護テープ１のうち、紙管２０のすぐ上に巻かれている一層目、および一層目の上に巻かれている二層目においては、電線保護テープ１を巻き付ける際に上層部分からテープ面に対して垂直に加わる抑え付け力によって帯状クッション材１２が上記垂直方向に圧縮され、圧縮されていない時（図１参照）に比べて薄くなった状態にある。なお、一層目および二層目において、カバーフィルム１４は、帯状クッション材１２が縮むのに合わせてその両側面からそれぞれ離脱してしわ部１８１，１８１を形成し、上層の粘着層１５，１６に当接されている。 As shown in FIG. 2, in the electric wire group protection tape 1 wound around the paper tube 20, the first layer wound just above the paper tube 20 and the second layer wound on the first layer. Compared to the case where the belt-like cushion material 12 is compressed in the vertical direction by the restraining force applied perpendicularly to the tape surface from the upper layer portion when the wire protection tape 1 is wound (see FIG. 1). It is in a thin state. In the first and second layers, the cover film 14 is separated from both side surfaces thereof as the band-shaped cushion material 12 shrinks to form wrinkle portions 181 and 181, and the upper adhesive layers 15 and 16 are formed. It is in contact.
　一方、２層目の上に巻き付けられる３層目では、図３のタイミングにおいてはまだ電線保護テープ１の上層部分から上記抑え付け力が加わっていない。このため、帯状クッション材１２は、圧縮されていない状態で巻き付け途中にある。この３層目の断面構造の状態は、電線保護テープ１を紙管２０から引き出して保護対象の電線群Ｗｇに巻き付けようとする時の膨出状態と一致している。 On the other hand, in the third layer wound on the second layer, the above-mentioned restraining force is not yet applied from the upper layer portion of the wire protection tape 1 at the timing of FIG. For this reason, the belt-like cushion material 12 is in the middle of winding in an uncompressed state. The state of the cross-sectional structure of the third layer coincides with the bulging state when the wire protection tape 1 is pulled out from the paper tube 20 and is wrapped around the wire group Wg to be protected.
　このように、電線保護テープ１は、製品として紙管２０に巻かれている時には帯状クッション材１２がテープ面に垂直な方向に縮んでおり（図２参照）、紙管２０から引き出して使用する時には帯状クッション材１２が元の状態に膨らむ（図１参照）構造である。すなわち、電線保護テープ１は、幅方向と直交する方向の厚さが薄くなるよう巻き付け得る製品構造である。この製品構造は、その後、紙管２０から引き出して電線群Ｗｇに螺旋状に巻き付ける際の作業効率を向上させる。 Thus, when the wire protection tape 1 is wound around the paper tube 20 as a product, the belt-like cushion material 12 is contracted in a direction perpendicular to the tape surface (see FIG. 2), and is used by being pulled out from the paper tube 20. In some cases, the belt-like cushion material 12 swells to its original state (see FIG. 1). That is, the electric wire protection tape 1 is a product structure that can be wound so that the thickness in the direction orthogonal to the width direction becomes thin. This product structure improves the working efficiency when it is pulled out from the paper tube 20 and wound around the wire group Wg in a spiral.
　次に、電線群保護テープ１の使い方および作用について図３を参照して説明する。
　図３は、本実施の形態に係る電線群保護テープの電線群に対する螺巻構造を示す模式的に示す図である。 Next, the usage and operation of the wire group protection tape 1 will be described with reference to FIG.
FIG. 3 is a diagram schematically illustrating a spiral structure of the wire group protection tape according to the present embodiment for the wire group.
　図３に示す螺巻構造とするための電線群保護テープ１の螺巻作業手順として、作業者は、まず、図３には示していない電線群保護テープ１のテープ材としての製品を手に持ち、紙管２０から巻き付けられている電線群保護テープ１の先端部を必要量巻き解く。次いで、巻き解き端の粘着層１５、１６のある面を電線群Ｗｇの前述したテープ長要保護領域の始端位置Ｓｔに当たる外周部に接着し、そこから電線群Ｗｇに対する巻き付けを開始する。 As a procedure for winding the wire group protection tape 1 for the screw structure shown in FIG. 3, the operator first has a product as a tape material for the wire group protection tape 1 not shown in FIG. Unwind the necessary amount of the tip of the wire group protection tape 1 held by the paper tube 20. Next, the surface having the unbonded end adhesive layers 15 and 16 is bonded to the outer peripheral portion of the electric wire group Wg corresponding to the start position St of the tape length required protection region, and winding of the electric wire group Wg is started therefrom.
　電線群Ｗｇに対する電線群保護テープ１の巻き付け作業においては、螺旋巻きにするために電線群Ｗｇの長さ方向に対して斜めの角度で巻き付け開始するとともに、巻き終えたテープの幅方向一端部に次に巻き付けようとするテープの幅方向の他端部が重なる肉厚が大きくなることを抑制されたオーバーラップ巻きで行う。 In the winding operation of the wire group protection tape 1 around the wire group Wg, winding is started at an oblique angle with respect to the length direction of the wire group Wg in order to make a spiral winding, and at the end in the width direction of the tape that has been wound. Next, it is performed by overlap winding in which an increase in the thickness at which the other end portion of the tape to be wound overlaps in the width direction is suppressed.
　この重ね巻きの作業は、例えば、ＰＶＣテープを巻き付けるときと同様に、紙管２０を逐次手で持ち替えながら電線群Ｗｇを中心にして繰り返し周回させることにより行うことができる。この螺巻作業を、図３の矢印Ｙ方向に重ね巻きが進行するように電線群Ｗｇの図示しないテープ長要保護領域の終端位置まで繰り返し実施する。 The lap winding operation can be performed, for example, by repeatedly turning around the electric wire group Wg while holding the paper tube 20 by hand as in the case of winding the PVC tape. This winding operation is repeated until the end position of the tape length protection area (not shown) of the wire group Wg so that the lap winding proceeds in the direction of arrow Y in FIG.

In FIG. 4, S1 and S2 show the tape area | region in the 1st round part and the 2nd round part at the time of winding the electric wire group protection tape 1 around the electric wire group Wg in FIG. .
　図４によれば、電線群Ｗｇに重ね巻きされる電線群保護テープ１において、先に巻き付けられた１周目部分の第２の帯状外装材１１の上部に２周目部分の第１の帯状外装材１０が重なるように重ね巻きが行われている。このように、先に巻き付けられた部分の第２の帯状外装材１１の上部に一周後に巻き付けられた部分の第１の帯状外装材１０が重ね巻きされる構造は、電線群Ｗｇの外周面に沿って、前述したテープ長要保護領域の終端位置まで螺旋状に連続的に形成される。 According to FIG. 4, in the electric wire group protection tape 1 wound around the electric wire group Wg, the first belt-like portion of the second round portion is formed on the upper portion of the second belt-shaped outer covering material 11 of the first round portion that is wound first. Overwrapping is performed so that the exterior material 10 overlaps. As described above, the structure in which the first belt-shaped sheathing material 10 of the portion wound after one round is wound around the upper portion of the second belt-shaped sheathing material 11 of the portion wound first is overlapped on the outer circumferential surface of the wire group Wg. Along the end of the tape long protection area, the tape is continuously formed in a spiral shape.
　前述したように、先に巻き付けられた部分の第２の帯状外装材１１の上部に一周後に巻き付けられた部分の第１の帯状外装材１０が重ね巻きされる構造部分を、以下では例えば平坦状外装帯１００と呼称する。 As described above, a structure portion in which the first belt-shaped exterior material 10 of the portion wound after one round is wound around the upper portion of the second belt-shaped exterior material 11 of the previously wound portion is, for example, a flat shape below. This will be referred to as an outer band 100.
　一方、図４において、帯状クッション材１２とその上面のクッション材保護用帯状外装材１３は、電線群保護テープ１の上述したテープ長要保護領域の終端位置までの連続した周回に亘って先に巻き付けられた部分と後で巻き付けられた部分とが重なり合うことはない。 On the other hand, in FIG. 4, the belt-like cushion material 12 and the cushion-like protective belt-like sheathing material 13 on the upper surface of the belt-like cushion material 12 are first passed over the continuous turn to the end position of the above-described tape length protection region of the wire group protection tape 1. The wound part and the part wound later do not overlap.
　このため、電線群Ｗｇに螺旋状に巻き付けられた電線群保護テープ１のうち、帯状クッション材１２は、紙管２０に巻き付けられているときの縮んだ状態から元の状態に膨らむ。この帯状クッション材１２の膨らみは、その上面のクッション材保護用帯状外装材１３を介して最上部のカバーフィルム１４を他の部分に比べて突出した形状に押し上げる。 For this reason, in the wire group protection tape 1 spirally wound around the wire group Wg, the belt-like cushion material 12 swells from the contracted state when wound around the paper tube 20 to the original state. The swelling of the belt-like cushion material 12 pushes up the uppermost cover film 14 to a shape protruding from the other portions via the cushion-like protective belt-like exterior material 13 on the upper surface thereof.
　これにより、電線群Ｗｇの外周面には、カバーフィルム１４が前述した帯状クッション材１２の膨らみによって突出される構造が、テープ長要保護領域の終端位置まで螺旋状に連続的に形成される。このように帯状クッション材１２の膨らみによって突出される構造が螺旋状に連なる構造部分を、以下では例えば突条外装帯２００と呼称する。 Thereby, on the outer peripheral surface of the wire group Wg, a structure in which the cover film 14 protrudes due to the swelling of the band-shaped cushion material 12 described above is continuously formed in a spiral manner up to the end position of the tape long protection area. The structure part in which the structure protruding by the swelling of the belt-like cushion material 12 is spirally connected in this manner is hereinafter referred to as, for example, a ridge outer belt 200.
　このように、本実施の形態に係る電線群保護テープ１は、電線群Ｗｇに対して図３に示す態様で螺巻することにより、保護対象である電線群Ｗｇの外周面に突条外装帯２００と平坦状外装帯１００とが隣接して螺旋状に連なる外装構造を形成する。この外装構造は、突条外装帯２００と平坦状外装帯１００とが螺旋形状に隣接することにより、既存のコルゲートチューブのような蛇腹形状の保護構造を形成する。 As described above, the wire group protection tape 1 according to the present embodiment is spirally wound around the wire group Wg in the form shown in FIG. 200 and the flat exterior belt | band | zone 100 adjoin and form the exterior structure which continues in a spiral. This exterior structure forms the bellows-shaped protective structure like the existing corrugated tube, when the protrusion exterior belt | band | zone 200 and the flat exterior belt | band | zone 100 adjoin a spiral shape.
　電線群Ｗｇに螺巻されることで雄ねじに類似する形状の保護構造を形成する電線保護テープ１（図３参照）において、突状外装帯２００は、外部部品が接触、あるいは衝突した際に、下地である帯状クッション材１２のクッション作用により、その衝撃を緩衝し、電線群Ｗｇ内の電線を保護する。 In the electric wire protection tape 1 (see FIG. 3) that forms a protective structure having a shape similar to that of a male screw by being wound around the electric wire group Wg, the protruding outer band 200 is in contact with or colliding with external parts. The cushioning action of the belt-like cushion material 12 as the base cushions the impact and protects the wires in the wire group Wg.
　また、平坦状外装帯１００は、下地である第１，第２の帯状外装帯１０，１１の幅分だけ突状外装帯２００の螺旋間に平坦部分を形成することと、該第１，第２の帯状外装帯１０，１１が持つ可撓性とによって、当該電線保護テープ１が螺巻された保護対象の電線群Ｗｇを曲げようとする際も、曲げる範囲を広くし、かつ、曲げ易くする。 Further, the flat outer strip 100 is formed by forming a flat portion between the spirals of the projecting outer strip 200 by the width of the first and second strip outer strips 10 and 11 as the base, When the wire group Wg to be protected, on which the wire protection tape 1 is wound, is bent due to the flexibility of the belt-like outer strips 10 and 11, the bending range is widened and it is easy to bend. To do.
　しかも、突状外装帯２００および平坦状外装帯１００は、いずれもその下地にポリプロピレンや、ポリエチレン等の合成樹脂材からなる耐突き刺し性を有する外装材（クッション材保護用帯状外装材１３および第１，第２の帯状外装材１０，１１）が存在するため、外部部品等のエッジ部や、例えばコルゲートチューブ内に挿入して用いる場合のコルゲートチューブのバリ等の侵入を防止できる。 In addition, the protruding outer band 200 and the flat outer band 100 are both stab-resistant outer covering materials (such as the band-shaped outer covering material 13 for cushioning material protection and the first covering member) made of a synthetic resin material such as polypropylene or polyethylene. , Second strip-shaped exterior materials 10, 11) can prevent entry of edge parts of external parts or the like, or burrs of the corrugated tube when inserted into the corrugated tube, for example.
　本実施の形態では、例えば第２の帯状外装材１１の上に一巻後の第１の帯状外装材１０が重なるようにして、電線群保護テープ１を電線群Ｗｇに螺巻するだけで、電線群Ｗｇの外周面に、圧縮されていない状態の帯状クッション材１２を下地とする突条外装帯２００と、第１，第２の帯状外装材１０，１１が重ね巻きされた平坦状外装帯２００からなる雄ねじに類似する形状の保護構造を形成することができ、既存のコルゲートチューブを用いる場合と同様、電線群Ｗｇの屈曲性を保ちながら電線の保護が図れる。 In the present embodiment, for example, the first band-shaped exterior material 10 after one turn is overlapped on the second band-shaped exterior material 11, and the wire group protection tape 1 is simply wound around the wire group Wg. A flat outer band in which a ridge outer band 200 having the uncompressed band-shaped cushion material 12 as a base, and first and second band-shaped outer members 10 and 11 are wound around the outer peripheral surface of the wire group Wg. A protective structure having a shape similar to a male screw made of 200 can be formed, and the wire can be protected while maintaining the flexibility of the wire group Wg as in the case of using an existing corrugated tube.
　また、本実施の形態では、紙管２０に巻き付けて製品化する際に帯状クッション材１２を強く圧縮させて巻き上げることで製品としての電線群保護テープ１の厚みを抑えることができ、電線群Ｗｇに巻き付ける螺巻作業の作業性を向上させることができる。特に、帯状クッション材１２を、第１，第２の帯状外装材１０，１１よりも高い部分を断面台形とすることで、紙管２０に巻かれる製品状態でのテープの厚さをさらに抑えることができ、電線群Ｗｇに螺巻する際の作業性を向上させることができる。 Moreover, in this Embodiment, when winding around the paper tube 20 and commercializing, the thickness of the wire group protection tape 1 as a product can be restrained by strongly compressing and winding up the strip | belt-shaped cushioning material 12, and the electric wire group Wg It is possible to improve the workability of the winding work to be wound around. In particular, the band-shaped cushioning material 12 has a trapezoidal cross section at a portion higher than the first and second belt-shaped exterior materials 10 and 11, thereby further reducing the thickness of the tape in the product state wound around the paper tube 20. The workability at the time of being wound around the wire group Wg can be improved.
　また、本実施の形態では、電線群保護テープ１が製品としてテープ巻きの構造を採ることで、保護対象の電線径に依らずに電線群を保護できるようになり、部品点数を抑え、部品の償却費を抑えることができる。また、本実施の形態では、上記製品化された電線群保護テープ１を引き出して電線群に螺巻するだけで電線群を保護することができるため、コルゲートチューブを含むハーネスを構築する場合に比べて工数を大幅に削減できる。 In the present embodiment, the wire group protection tape 1 adopts a tape winding structure as a product, so that the wire group can be protected regardless of the diameter of the wire to be protected, the number of parts is reduced, Amortization expenses can be reduced. Moreover, in this Embodiment, since an electric wire group can be protected only by pulling out the commercialized electric wire group protection tape 1 and screwing around the electric wire group, compared with the case where a harness including a corrugated tube is constructed. The man-hour can be greatly reduced.
　また、本実施の形態では、帯状クッション材１２上にクッション材保護用帯状外装材１３を配置しているため、コルゲートチューブでは得られない緩衝効果を得ることができ、緩衝材の代用品としての使用も可能となる。 Moreover, in this Embodiment, since the strip | belt-shaped exterior packaging material 13 for cushioning material protection is arrange | positioned on the strip | belt-shaped cushioning material 12, the buffer effect which cannot be obtained with a corrugated tube can be acquired, and as a substitute of a cushioning material Use is also possible.
　以上のように、本実施の形態に係る電線群保護テープ１は、電線群Ｗｇにオーバーラップ幅を一定に保って肉厚が大きくなることを抑制されたオーバーラップ巻きが容易にできるとともに、耐突き刺し性と振動遮断性を有し、電線群Ｗｇの屈曲性が保てる。 As described above, the wire group protection tape 1 according to the present embodiment can easily overlap the wire group Wg while keeping the overlap width constant and prevent the wall thickness from becoming large. It has piercing properties and vibration isolation properties, and the flexibility of the wire group Wg can be maintained.
　（第２の実施の形態） (Second embodiment)
　図５に示すように、本発明の第２の実施の形態に係る電線群保護テープ１Ａは、電線群Ｗｇを螺巻できる可撓性を有する第１，第２の帯状外装材１０Ａ，１１Ａと、第１，第２の帯状外装材１０Ａ，１１Ａよりも少なくとも２倍以上の厚さを有する帯状クッション材１２Ａと、電線群Ｗｇを螺巻できる可撓性を有し、帯状クッション材１２Ａの上面部に接着状態に載置されたクッション材保護用帯状外装材１３Ａと、帯状クッション材１２Ａが圧縮されない状態に、第１，第２の帯状外装材１０Ａ，１１Ａおよびクッション材保護用帯状外装材１３Ａの上面部に接着されたカバーフィルム１４Ａと、少なくとも第１，第２の帯状外装材１０Ａ，１１Ａの下面に形成された粘着層１５Ａ，１６Ａと、を備えている。 As shown in FIG. 5, the wire group protection tape 1A according to the second embodiment of the present invention includes flexible first and second strip-shaped exterior materials 10A and 11A that can be wound around the wire group Wg. The upper and lower surfaces of the belt-like cushion material 12A having the flexibility of being able to screw the wire-like group Wg and the belt-like cushion material 12A having a thickness at least twice that of the first and second belt-like exterior materials 10A and 11A. The first and second belt-like exterior materials 10A and 11A and the cushion-material-protecting belt-like sheath material 13A in a state where the belt-like sheath material 13A for cushioning material placed in the adhesive state and the belt-like cushion material 12A are not compressed. Cover film 14A adhered to the upper surface portion of the film and adhesive layers 15A and 16A formed on the lower surfaces of at least the first and second strip-shaped exterior materials 10A and 11A.
　帯状クッション材１２Ａは、断面矩形であり、底面部を第１，第２の帯状外装材１０Ａ，１１Ａの底面部と面一となるように一致させて第１，第２の帯状外装材１０Ａ，１１Ａ間に位置されている。また、帯状クッション材１２Ａは、両側の第１，第２の帯状外装材１０Ａ，１１Ａと側面部同士を接着されている。 The belt-like cushioning material 12A has a rectangular cross section, and the first and second belt- like packaging materials 10A, 10A, 11A. Further, the belt-like cushion material 12A is bonded to the first and second belt-like exterior materials 10A and 11A on both sides and the side portions.
　クッション材保護用帯状外装材１３Ａは、帯状クッション材１２Ａの上面部より幅方向両側に張り出して帯状クッション材１２Ａの上面部に接着されている。カバーフィルム１４Ａは、帯状クッション材１２Ａの側面部から離間している。 The belt-shaped exterior material 13A for protecting the cushion material projects from the upper surface portion of the belt-shaped cushion material 12A to both sides in the width direction and is bonded to the upper surface portion of the belt-shaped cushion material 12A. The cover film 14A is separated from the side surface portion of the belt-like cushion material 12A.
　クッション材保護用帯状外装材１３Ａが帯状クッション材１２Ａの上面部より幅方向両側に張り出し、その上から第１，第２の帯状外装材１０Ａ，１１Ａの上面部にかけてカバーフィルム１４Ａで覆う図５の構成によれば、カバーフィルム１４Ａと、第１，第２の帯状外装材１０Ａ，１１Ａ、帯状クッション材１２Ａ、およびクッション材保護用帯状外装材１３Ａ間に空間Ｓ１およびＳ２が形成される。 In FIG. 5, the belt-shaped exterior material 13A for protecting the cushion material projects from the upper surface of the belt-shaped cushion material 12A to both sides in the width direction, and covers the upper surface of the first and second belt-shaped exterior materials 10A and 11A from above. According to the configuration, spaces S1 and S2 are formed between the cover film 14A and the first and second strip-shaped exterior members 10A and 11A, the strip-shaped cushion member 12A, and the cushion-protecting strip-shaped exterior member 13A.
　電線群保護テープ１Ａにおいて、第１，第２の帯状外装材１０Ａ，１１Ａ、帯状クッション材１２Ａ、クッション材保護用帯状外装材１３Ａ、カバーフィルム１４Ａの材質は、それぞれ、第１実施の形態に係る電線群保護テープ１における第１，第２の帯状外装材１０，１１、帯状クッション材１２、クッション材保護用帯状外装材１３、カバーフィルム１４の材質と同等のものである。 In the wire group protection tape 1A, the materials of the first and second strip-shaped exterior materials 10A and 11A, the strip-shaped cushion material 12A, the cushion-material-protective strip-shaped exterior material 13A, and the cover film 14A are related to the first embodiment. It is the same as the material of the 1st, 2nd strip | belt-shaped cladding | exterior_material 10,11 in the electric wire group protection tape 1, the strip | belt-shaped cushioning material 12, the strip | belt-shaped cladding | exterior_material 13 for cushioning material protection, and the cover film 14. FIG.
　電線群保護テープ１Ａの使い方についても第１の実施の形態に係る電線群保護テープ１Ａと同様である。すなわち、電線群保護テープ１Ａは、図２に示す電線群保護テープ１Ａと同様、電線群Ｗｇに対して螺巻することにより電線群Ｗｇの保護を図るものである。 The usage of the wire group protection tape 1A is also the same as that of the wire group protection tape 1A according to the first embodiment. That is, the wire group protection tape 1A, like the wire group protection tape 1A shown in FIG. 2, is intended to protect the wire group Wg by being wound around the wire group Wg.
　螺巻作業においては、電線群保護テープ１Ａを、第１，第２の帯状外装材１０Ａ，１１Ａを重ね代として電線群Ｗｇに重ね巻きにより螺巻することで、圧縮されていない状態の帯状クッション材１２Ａを下地とする、第１の実施の形態における突条外装帯２００と同等の突条外装帯２００Ａが電線群Ｗｇの外周面に螺旋状に形成される。 In the winding operation, the wire group protection tape 1A is wound around the wire group Wg by overlapping winding with the first and second strip-shaped exterior materials 10A and 11A being overlapped, so that the band-shaped cushion is not compressed. A strip outer strip 200A equivalent to the strip outer strip 200 in the first embodiment, with the material 12A as a base, is formed in a spiral shape on the outer peripheral surface of the wire group Wg.
　また、突条外装帯２００Ａの両側には、第１，第２の帯状外装材１０Ａ，１１Ａが重ね巻きされた、第１の実施の形態における平坦状外装帯１００と同等の平坦状外装帯１００Ａが螺旋状に形成される。よって、本実施の形態においても、電線群保護テープ１Ａを保護対象の電線群Ｗｇに螺巻するだけで、コルゲートチューブの外観のような蛇腹形状の外装構造を形成することができる。 In addition, a flat outer strip 100A equivalent to the flat outer strip 100 in the first embodiment, in which the first and second strip-shaped outer strips 10A and 11A are overlapped on both sides of the ridge outer strip 200A. Is formed in a spiral shape. Therefore, also in the present embodiment, it is possible to form an accordion-shaped exterior structure like the appearance of a corrugated tube only by screwing the wire group protection tape 1A around the wire group Wg to be protected.
　上記外装構造において、平坦状外装帯１００Ａは、クッション材が介在しないために衝撃緩衝機能はないが、第１，第２の帯状外装材１０Ａ，１１Ａを重ね巻きしたものであることから、外部部品のエッジやバリ等の侵入から電線群Ｗｇを保護する機能を有する。また、この平坦状外装帯１００Ａを配したことにより、電線群Ｗｇの屈曲性を向上させることができる。一方、突条外装帯２００Ａは、下地が帯状クッション材１２Ａであるため、外部部品からの衝撃が加わっても緩衝材として働き、電線群Ｗｇを保護することができる。 In the above exterior structure, the flat exterior band 100A does not have an impact buffering function because no cushion material is interposed. However, the flat exterior band 100A is formed by wrapping the first and second belt-shaped exterior members 10A and 11A, so that an external component is used. It has a function of protecting the wire group Wg from intrusion of edges and burrs. Moreover, the flexibility of the electric wire group Wg can be improved by providing the flat outer strip 100A. On the other hand, since the base of the ridge exterior band 200A is the band-shaped cushioning material 12A, even if an impact from an external component is applied, it acts as a buffer material and can protect the wire group Wg.
　また、本実施の形態では、クッション材保護用帯状外装材１３Ａが帯状クッション材１２Ａの上面部より幅方向両側に張り出し、その上から第１，第２の帯状外装材１０Ａ，１１Ａの上面部にかけてカバーフィルム１４Ａにより覆う構成（図５参照）を有するため、上記幅方向に直交する方向からの干渉に対して強い保護機能を発揮する。 Further, in the present embodiment, the cushion material protecting strip-shaped exterior material 13A projects from the top surface portion of the strip-shaped cushion material 12A to both sides in the width direction, and extends from there to the top surface portions of the first and second strip-shaped exterior materials 10A, 11A. Since it has the structure (refer FIG. 5) covered with the cover film 14A, a strong protection function is exhibited with respect to the interference from the direction orthogonal to the said width direction.
　図６は、本実施の形態に係る電線群保護テープの外部から干渉を受けた際の状態を模式的に示す断面図である。
　図６においては、電線群保護テープ１Ａ（図５参照）を電線群Ｗｇに対して螺巻した状態で突条外装帯２００Ａに対して矢印方向、すなわちテープ幅方向に直交する方向（テープの表面に対して垂直な方向）から干渉を受けた場合の様子を示している。 FIG. 6 is a cross-sectional view schematically showing a state when interference is received from the outside of the wire group protection tape according to the present embodiment.
In FIG. 6, the wire group protection tape 1 </ b> A (see FIG. 5) is wound around the wire group Wg and is in the direction of the arrow, that is, the direction perpendicular to the tape width direction (the tape surface). It shows a state in the case of receiving interference from a direction perpendicular to.
　図６において、矢印で示す方向からの干渉があると、断面矩形の帯状クッション材１２ｇはその干渉力を受けて圧縮され、空間Ｓ１，Ｓ２の容量は次第に小さくなっていく。ここで、クッション材保護用帯状外装材１３Ａが帯状クッション材１２Ａの上面部より幅方向両側に張り出した構造となっているため、上記干渉力次第では、クッション材保護用帯状外装材１３Ａの下面部が第１，第２の帯状外装材１０Ａ，１１Ａの上面部に接するように帯状クッション材１２Ａが縮んだ状態となる。この状態は、上記干渉方向から見て、第１，第２の帯状外装材１０Ａ，１１Ａおよびクッション材保護用帯状外装材１３Ａ間にテープ幅方向の隙間がない状態である。 In FIG. 6, when there is interference from the direction indicated by the arrow, the band-shaped cushion material 12g having a rectangular cross section is compressed by receiving the interference force, and the capacity of the spaces S1 and S2 gradually decreases. Here, since the belt-shaped exterior material 13A for cushioning material protection has a structure projecting to both sides in the width direction from the upper surface of the belt-shaped cushioning material 12A, depending on the interference force, the lower surface portion of the belt-shaped exterior material 13A for cushioning material protection However, the belt-like cushion material 12A is contracted so as to be in contact with the upper surface portions of the first and second belt-like exterior materials 10A and 11A. This state is a state where there is no gap in the tape width direction between the first and second strip-shaped exterior members 10A and 11A and the cushion-protecting strip-shaped exterior member 13A as viewed from the interference direction.
　図６に示す状態では、第１，第２の帯状外装材１０Ａ，１１Ａおよびクッション材保護用帯状外装材１３Ａを超えて外部部材のエッジ部やバリ等が侵入する隙間がないため、既存のコルゲートチューブと遜色のない電線の保護が可能となる。また、電線群保護テープ１Ａは、図６の状態以外の場合には、クッション材保護用帯状外装材１３Ａがカバーフィルム１４Ａを介して外部部品と接触した時に圧縮されて衝撃を吸収する等、第１の実施の形態に係る電線群保護テープ１と同様の電線保護機能を有する。 In the state shown in FIG. 6, there is no clearance for the edge portion, burrs, and the like of the external member to enter beyond the first and second strip-shaped exterior materials 10A and 11A and the cushion-shaped protective strip-shaped exterior material 13A. It is possible to protect the wires that are inferior to the tube. Further, in the case other than the state of FIG. 6, the wire group protection tape 1A is compressed when the cushion material protection strip-shaped exterior material 13A comes into contact with an external part through the cover film 14A and absorbs an impact, etc. It has the same electric wire protection function as electric wire group protection tape 1 concerning one embodiment.
　本実施の形態では、電線群保護テープ１Ａを、第１，第２の帯状外装材１０Ａ，１１Ａを重ね代として電線群Ｗｇに螺巻することで、電線群Ｗｇの外周面に、圧縮されていない状態の帯状クッション材１２Ａを下地とする突条外装帯２００Ａと、第１，第２の帯状外装材１０Ａ，１１Ａが重ねて巻かれた平坦状外装帯１００Ａが隣接した蛇腹形状の外装構造を形成することができ、これにより、第１の実施の形態と同一の効果が得られる。 In the present embodiment, the electric wire group protection tape 1A is compressed on the outer peripheral surface of the electric wire group Wg by being wound around the electric wire group Wg with the first and second strip-shaped exterior materials 10A and 11A being overlapped. A bellows-shaped exterior structure in which a strip-shaped exterior strip 200A with the strip-shaped cushion member 12A in an unexposed state and a flat exterior strip 100A on which the first and second strip-shaped exterior members 10A and 11A are overlapped and wound are adjacent to each other. Thus, the same effect as in the first embodiment can be obtained.
　特に、本実施の形態では、帯状クッション材１２Ａが断面矩形状に形成され、クッション材保護用帯状外装材１３Ａが帯状クッション材１２Ａの上面部より幅方向両側に張り出した構造を有するため、上記幅方向からの干渉を受けて帯状クッション材１２Ａが圧縮されることで、斜め外方から見て、第１，第２の帯状外装材１０Ａ，１１Ａおよびクッション材保護用帯状外装材１３Ａ間にテープ幅方向の隙間がない状態とすることができ、上記干渉方向からのエッジやバリ等の侵入を防止し、高い電線保護機能を発揮できる。 In particular, in the present embodiment, the belt-like cushion material 12A is formed in a rectangular cross section, and the cushion-material-protecting belt-like exterior material 13A has a structure projecting from the upper surface of the belt-like cushion material 12A to both sides in the width direction. When the belt-shaped cushioning material 12A is compressed in response to interference from the direction, the tape width between the first and second belt-shaped packaging materials 10A and 11A and the cushioning material protection belt-shaped packaging material 13A is seen obliquely from the outside. It is possible to achieve a state in which there is no gap in the direction, and it is possible to prevent intrusion of edges, burrs and the like from the interference direction, and to exhibit a high electric wire protection function.

In the meantime, a second flat outer band (referred to as a reference numeral 100B-2 for convenience) is formed by winding a single layer of the second band outer material 10B-2.
　このように、本実施の形態においても、電線群保護テープ１Ｂを保護対象の電線群Ｗｇに螺巻するだけで、コルゲートチューブの外観のような蛇腹形状を有する外装構造を形成することができる。 Thus, also in the present embodiment, it is possible to form an exterior structure having a bellows shape like the appearance of a corrugated tube by simply winding the wire group protection tape 1B around the wire group Wg to be protected.
　上記外装構造において、２つの突条外装帯２００Ｂ－１，２００Ｂ－２は、下地が帯状クッション材１２Ｂ－１，１２Ｂ－２であるため、外部部品からの衝撃があっても緩衝材として働き、電線群Ｗｇを保護することができる。 In the above exterior structure, the two ridge exterior bands 200B-1 and 200B-2 work as cushioning materials even if there is an impact from an external component because the base is the band-shaped cushion material 12B-1 or 12B-2. The electric wire group Wg can be protected.
　一方、突条外装帯２００Ｂ－１，２００Ｂ－２に隣接する第１，第２の平坦状外装帯１００Ｂ－１，１００Ｂ－２は、クッション材が介在しないために緩衝機能はないが、第１，第３の帯状外装材１０Ｂ－１，１０Ｂ－３の重ね巻き、あるいは第２の帯状外装材１０Ｂ－２の単層巻きからなるため、エッジやバリ等による損傷から電線群Ｗｇを保護する機能を有している。また、上記平坦状外装帯１００Ｂ－１，１００Ｂ－２を配した構造によれば、電線群Ｗｇの屈曲性を良好なものとすることができる。 On the other hand, the first and second flat outer strips 100B-1 and 100B-2 adjacent to the ridge outer strips 200B-1 and 200B-2 have no cushioning function because no cushion material is interposed therebetween. , The third belt-like exterior material 10B-1, 10B-3, or the second belt-like exterior material 10B-2 is a single layer winding, so that the wire group Wg can be protected from damage caused by edges, burrs, etc. have. Further, according to the structure in which the flat exterior bands 100B-1 and 100B-2 are arranged, the flexibility of the wire group Wg can be improved.
［第３の実施の形態の効果］
　本実施の形態では、電線群保護テープ１Ｂを、第１，第３の帯状外装材１０Ｂ－１，１０Ｂ－３を重ね代として電線群Ｗｇに螺巻するだけで、電線群Ｗｇの外周面に、圧縮されていない状態の帯状クッション材１２Ｂ－１，１２Ｂ－２ｂを下地とする２つの突条外装帯２００Ｂ－１，２００Ｂ－２と、第１，第３の帯状外装材１０Ｂ－１，１０Ｂ－３の重ね巻き、および第２の帯状外装材１０Ｂ－２単層による平坦状外装帯１００Ｂ－１，１００Ｂ－２を有する外装構造を形成することができ、これにより、第１の実施の形態と同一の電線保護効果が得られる。 [Effect of the third embodiment]

　例えば、第１の実施の形態において、電線群保護テープ１は、第１，第２の帯状外装帯１０，１１とクッション材保護用帯状外装材１３の厚さを同じにしているが、クッション材保護用帯状外装材１３の厚さを、第１，第２の帯状外装帯１０，１１の厚さよりも薄く形成した構造としてもよい。この点については、第２および第３の実施の形態でも同様である。これにより、紙管２０に多重に巻き付けた製品状態においてテープの厚さをより薄くでき、その後の螺巻作業のし易さに繋がる。 For example, in the first embodiment, the wire group protection tape 1 has the same thickness as the first and second strip-shaped exterior strips 10 and 11 and the cushion-protecting strip-shaped exterior member 13. The thickness of the protective strip-shaped exterior material 13 may be made thinner than the thickness of the first and second strip-shaped exterior strips 10 and 11. This is the same in the second and third embodiments. As a result, the thickness of the tape can be made thinner in the product state in which the paper tube 20 is wrapped around the paper tube 20, which leads to the ease of the subsequent winding operation.
　また、第１の実施の形態において、電線群保護テープ１は、一つのテープ内に１つのクッション材保護用帯状外装材１３（および帯状クッション材１２）と、２つの帯状外装材１０，１１を配置した構造としているが、一つのテープ内により多数のクッション材保護用帯状外装材（および帯状クッション材）、帯状外装材を配置した構造としてもよい。この点についても、第２および第３の実施の形態も同様である。 Moreover, in 1st Embodiment, the electric wire group protection tape 1 has the strip | belt-shaped exterior material 13 for cushion material protection (and strip | belt-shaped cushion material 12), and the two strip-shaped exterior materials 10 and 11 in one tape. Although the structure is arranged, it is also possible to adopt a structure in which a number of cushioning material protective strips (and striped cushions) and strips are arranged in one tape. This also applies to the second and third embodiments.
　また、電線群保護テープ１の帯状クッション材１２は、断面台形とする構造を例示したが、断面矩形のものを採用してもよい。この点は、第３の実施の形態においても同様である。また、粘着層については、第２および第３の実施形態においても、帯状外装材の下面のみならず、帯状クッション材を含む下面全体に形成する構成としてもよい。 Moreover, although the band-shaped cushion material 12 of the electric wire group protection tape 1 has exemplified a structure having a trapezoidal cross section, a rectangular cross section may be adopted. This is the same in the third embodiment. Moreover, about the adhesion layer, it is good also as a structure formed not only in the lower surface of a strip | belt-shaped exterior material but in the whole lower surface containing a strip | belt-shaped cushion material also in 2nd and 3rd embodiment.
　以上説明したように、本発明に係る電線群保護テープは、電線群にオーバーラップ幅を一定に保って肉厚が大きくなることを抑制されたオーバーラップ巻きが容易にできるとともに、耐突き刺し性と振動遮断性を有するという効果を有し、電線群に螺巻してコルゲートチューブと同等に電線群を保護する電線群保護テープ全般に有用である。 As described above, the wire group protection tape according to the present invention can easily overlap the wire group and keep the overlap width constant and prevent the wall thickness from becoming large, and has a puncture resistance. It has the effect of having vibration isolation, and is useful for all wire group protection tapes that are wound around a wire group and protect the wire group in the same manner as a corrugated tube.
