Description

本発明は、電力供給や信号の送受信などの被覆導線をシースで覆って一体化した平型ケーブルに関するものである。 The present invention relates to a flat cable in which a sheathed conductor for power supply and signal transmission / reception is covered with a sheath and integrated.

夫々絶縁性の被覆材によって被覆された複数の被覆電力供給用導線と被覆アース用導線を、絶縁性のシースによって被覆して一体化した平型ケーブルが知られている。また、被覆電力供給用導線と信号の送受信を行なう被覆通信用導線などをシースによって被覆して一体化した平型の複合ケーブルも知られている。 A flat cable is known in which a plurality of covered power supply conductors and a covered earth conductor, each covered with an insulating covering material, are covered and integrated with an insulating sheath. Also known is a flat composite cable in which a sheathed power supply conductor and a sheathed communication conductor for transmitting and receiving signals are covered and integrated with a sheath.

この種の平型ケーブルでは、敷設時に電力供給用導線と、アース用導線や通信用導線とを分離する必要がある。この分離作業を容易に行なうことができるように、たとえば、特許文献１では、シースを断面８字状に形成し、被覆電力供給用導線と被覆アース用導線との間を薄肉に形成している。そして、被覆アース用導線のシースを被覆電力供給導線のシースに対して引っ張ることで、シースを薄肉部分で引き裂いて、被覆電力供給用導線と被覆アース用導線を分離できるようにしている。 In this type of flat cable, it is necessary to separate the power supply conductor from the ground conductor and the communication conductor when laying. In order to facilitate this separation operation, for example, in Patent Document 1, the sheath is formed in an 8-shaped cross section, and the space between the coated power supply conductor and the coated ground conductor is formed thin. . Then, by pulling the sheath of the sheathed ground conductor with respect to the sheath of the sheathed power supply conductor, the sheath is torn at the thin portion so that the sheathed power supply conductor and the sheathed ground conductor can be separated.

しかしながら、被覆電力供給用導線と被覆アース用導線との間でシースを引き裂いて分離した後、被覆アース用導線を敷設する際に、被覆アース用導線に被さっているシースを取り去る必要がある。このとき、アース用導線の被覆材が傷付かないようにシースを剥ぎ取る作業は、手間と時間が掛かり、作業効率の低下を招く。 However, after the sheath is torn and separated between the sheathed power supply conductor and the sheathed ground conductor, the sheath covering the sheathed ground conductor must be removed when the sheathed ground conductor is laid. At this time, the work of peeling off the sheath so as not to damage the covering material of the grounding conductor takes time and effort, and causes a reduction in work efficiency.

本発明の目的は、一方の被覆導線側のシースを引っ張ってシースを分離した後、この被覆導線を覆うシースも容易に取り去ることができる平型ケーブルを提供することである。 An object of the present invention is to provide a flat cable in which a sheath covering one of the coated conductors can be easily removed after the sheath on the side of one of the coated conductors is pulled to separate the sheath.

上記課題を解決するために、本発明の平型ケーブルは、
第１導線と前記第１導線を被覆する絶縁性の第１被覆材とを含む１又は複数の被覆第１導線と、
第２導線と前記第２導線を被覆する絶縁性の第２被覆材とを含む１又は複数の被覆第２導線と、
前記被覆第１導線と前記被覆第２導線を被覆して一体化する絶縁性のシースと、
を含む平型ケーブルであって、
前記シースは、被覆第１導線と前記被覆第２導線との間の長手方向に沿う両面に凹部が形成された括れ部を有し、前記括れ部の各凹部には、前記被覆第１導線に向けて溝状の切断可能部が凹設されており、
前記被覆第１導線側のシースを前記被覆第２導線側のシースに対して引っ張ることで、前記シースは、前記切断可能部にて分断され、前記被覆第１導線を被覆するシースが、前記切断可能部間の前記被覆第２導線側に残る残留部を残して、前記被覆第１導線と共に引き剥がされ、
前記被覆第１導線は、引き剥がされた前記被覆第１導線を被覆するシースの前記切断可能部間に形成された空隙から引き出し可能となっている、 In order to solve the above problems, the flat cable of the present invention is
One or a plurality of covered first conductive wires including a first conductive wire and an insulating first covering material covering the first conductive wire;
One or a plurality of covered second conductive wires including a second conductive wire and an insulating second covering material covering the second conductive wire;
An insulating sheath that covers and integrates the coated first conducting wire and the coated second conducting wire;
A flat cable including
The sheath has a constricted portion in which concave portions are formed on both surfaces along a longitudinal direction between the coated first conductive wire and the coated second conductive wire, and each concave portion of the constricted portion includes the constricted first conductive wire. A groove-shaped cutable part is recessed toward the
By pulling the sheath on the coated first conducting wire side with respect to the sheath on the coated second conducting wire side, the sheath is divided at the cuttable portion, and the sheath covering the coated first conducting wire is cut off The remaining portion remaining on the side of the coated second conducting wire between the possible parts is peeled off with the coated first conducting wire,
The covered first conducting wire can be drawn out from a gap formed between the cuttable portions of the sheath covering the peeled covered first conducting wire.

前記切断可能部は、前記空隙の幅が、前記被覆第１導線の直径よりも小さくなるように前記括れ部の凹部に形成されることが望ましい。 The cuttable portion is preferably formed in the concave portion of the constricted portion so that the width of the gap is smaller than the diameter of the covered first conducting wire.

本発明の平型ケーブルによれば、被覆第１導線側のシースを被覆第２導線側のシースに対して引っ張ることで、被覆第１導線を被覆するシースは、被覆第１導線と共に引き剥がされる。引き剥がされた被覆第１導線を被覆するシースは、切断可能部間に空隙が形成されている。従って、この空隙から被覆第１導線を引き出すことで、被覆第１導線を被覆するシースを容易に剥ぎ取ることができる。 According to the flat cable of the present invention, the sheath covering the coated first conductive wire is pulled off together with the coated first conductive wire by pulling the sheath on the coated first conductive wire side with respect to the sheath on the coated second conductive wire side. . In the sheath covering the peeled coated first conducting wire, a gap is formed between the cuttable portions. Therefore, the sheath covering the covered first conductive wire can be easily peeled off by pulling out the covered first conductive wire from this gap.

また、被覆第１導線を被覆するシースは、残留部のみが被覆第２導線側のシースに残るだけであるので、見栄えが良く、残留部を除去する必要もない。 Further, since the sheath covering the coated first conducting wire only has the remaining portion remaining in the sheath on the coated second conducting wire side, the appearance is good and it is not necessary to remove the remaining portion.

切断可能部は、残留部の先端の幅を、被覆第１導線の直径よりも小さくなるように形成することで、被覆第１導線側のシースを被覆第２導線側のシースに対して引っ張ったときに、被覆第１導線とこれを被覆するシースがばらばらにならないので、作業性を可及的に向上させることができる。 The cuttable portion is formed such that the width of the tip of the remaining portion is smaller than the diameter of the covered first conducting wire, thereby pulling the sheath on the covering first conducting wire side with respect to the sheath on the covering second conducting wire side. Sometimes, the coated first conducting wire and the sheath covering the first conductive wire are not separated, so that workability can be improved as much as possible.

以下、本発明の一実施例に係る平型ケーブル１０について、図面を参照しながら説明を行なう。 Hereinafter, a flat cable 10 according to an embodiment of the present invention will be described with reference to the drawings.

図１に示すように、本発明の平型ケーブル１０は、被覆第１導線２０と被覆第２導線３０を並列に並べ、絶縁性のシース４０によって被覆して構成することができる。図示の実施形態では、被覆第１導線２０を１本、被覆第２導線３０を２本としているが、本数はこれに限定されるものではない。 As shown in FIG. 1, the flat cable 10 of the present invention can be configured by arranging a covered first conducting wire 20 and a covering second conducting wire 30 in parallel and covering with an insulating sheath 40. In the illustrated embodiment, one covered first conducting wire 20 and two covered second conducting wires 30 are provided, but the number is not limited to this.

被覆第１導線２０は、導電性の第１導線２２の周囲を絶縁性の第１被覆材２４で覆って構成することができる。また、被覆第２導線３０は、導電性の第２導線３２の周囲を絶縁性の第２被覆材３４で覆って構成することができる。 The covered first conductive wire 20 can be configured by covering the periphery of the conductive first conductive wire 22 with an insulating first covering material 24. The coated second conductive wire 30 can be configured by covering the periphery of the conductive second conductive wire 32 with an insulating second coating material 34.

たとえば、第１導線２２をアース用導線、第２導線３２を電力供給用導線とすることができる。また、第１導線２２や第２導線３２を通信用導線などとすることもできる。第１導線２２及び第２導線３２は、夫々単線、撚り線、撚り対線、シールド線、同軸ケーブル、光ケーブル、テンションメンバー等を採用することができる。 For example, the first conductor 22 can be a ground conductor, and the second conductor 32 can be a power supply conductor. Moreover, the 1st conducting wire 22 and the 2nd conducting wire 32 can also be used as the conducting wire for communication. As the first conducting wire 22 and the second conducting wire 32, a single wire, a stranded wire, a twisted pair wire, a shielded wire, a coaxial cable, an optical cable, a tension member, or the like can be adopted.

また、第１被覆材２４、第２被覆材３４として、ポリ塩化ビニル、ポリエチレン、フッ素樹脂、ポリエステル、ポリエチレンテレフタレート、エチレン酢酸ビニル共重合体、エチレンポリプロピレンゴム、クロロプレンゴム、変性ポリフェニレンエーテル樹脂、エチレンエチル共重合体、ポリウレタンなどの絶縁性、可撓性、耐熱性、耐水性、難燃性を有する材料を採用することができる。 Further, as the first covering material 24 and the second covering material 34, polyvinyl chloride, polyethylene, fluororesin, polyester, polyethylene terephthalate, ethylene vinyl acetate copolymer, ethylene polypropylene rubber, chloroprene rubber, modified polyphenylene ether resin, ethylene ethyl A material having insulating properties, flexibility, heat resistance, water resistance, and flame retardancy, such as a copolymer or polyurethane, can be employed.

被覆第１導線２０と被覆第２導線３０を一体に被覆するシース４０として、ポリ塩化ビニル、ポリエチレン、フッ素樹脂、ポリエステル、ポリエチレンテレフタレート、エチレン酢酸ビニル共重合体、エチレンポリプロピレンゴム、クロロプレンゴム、変性ポリフェニレンエーテル樹脂、エチレンエチル共重合体、ポリウレタンなどの絶縁性、可撓性、耐熱性、耐水性、難燃性を有する材料を採用することができる。 As the sheath 40 for covering the coated first conductive wire 20 and the coated second conductive wire 30 integrally, polyvinyl chloride, polyethylene, fluororesin, polyester, polyethylene terephthalate, ethylene vinyl acetate copolymer, ethylene polypropylene rubber, chloroprene rubber, modified polyphenylene A material having insulating properties, flexibility, heat resistance, water resistance, and flame retardancy, such as ether resin, ethylene ethyl copolymer, and polyurethane can be employed.

シース４０は、被覆第１導線２０と前記被覆第２導線３０との間に長手方向に沿う両面に凹部４２が形成された括れ部４１を有するように、これら被覆導線２０，３０を被覆する。望ましくは、第１シース４７の厚さは、０．２ｍｍ〜１．０ｍｍ、第２シース４９の厚さは、１．０ｍｍ〜２．０ｍｍとする。 The sheath 40 covers the covered conductors 20 and 30 so as to have a constricted portion 41 having recesses 42 formed on both surfaces along the longitudinal direction between the covered first conductor 20 and the covered second conductor 30. Desirably, the thickness of the first sheath 47 is 0.2 mm to 1.0 mm, and the thickness of the second sheath 49 is 1.0 mm to 2.0 mm.

シース４０の括れ部４１の各凹部４２には、被覆第１導線２０に向けて溝状の切断可能部４３が夫々凹設されている。切断可能部４３の間隔は、被覆第１導線２０の直径よりも小さくすることが望ましい。この理由については後述する。 In each of the concave portions 42 of the constricted portion 41 of the sheath 40, a groove-shaped cutable portion 43 is provided so as to be recessed toward the coated first conductive wire 20. It is desirable that the interval between the cutable portions 43 be smaller than the diameter of the covered first conducting wire 20. The reason for this will be described later.

また、切断可能部４３の深さは、第１シース４７を第２シース４９に対して手で引っ張って、切断可能部４３にてシース４０を切断することができるが、通常の使用状態（たとえば、敷設時や敷設後）では容易に切断されない厚さとする。たとえば、切断可能部４３は、シース４０の厚さを０．０５ｍｍ〜０．３ｍｍ残す深さに形成することが好適である。 Further, the depth of the severable portion 43 is such that the sheath 40 can be cut by the severable portion 43 by pulling the first sheath 47 with respect to the second sheath 49 by hand. The thickness should not be easily cut during or after laying. For example, the cutable portion 43 is preferably formed to a depth that leaves the thickness of the sheath 40 between 0.05 mm and 0.3 mm.

上記のようなシース４０による被覆第１導線２０と被覆第２導線３０の被覆は、押出成型によって実施することができる。なお、押出成型により、括れ部４１と切断可能部４３を同時に形成することもできるし、括れ部４１のみをシース４０に形成した後、括れ部４１の凹部４２にカッターや回転刃などを用いて切断可能部４３を別途形成するようにしてもよい。 The covering of the covered first conducting wire 20 and the covering second conducting wire 30 with the sheath 40 as described above can be performed by extrusion molding. It is to be noted that the constricted portion 41 and the cuttable portion 43 can be formed at the same time by extrusion molding. Alternatively, after forming only the constricted portion 41 on the sheath 40, a cutter or a rotary blade is used for the concave portion 42 of the constricted portion 41. The cuttable portion 43 may be formed separately.

作成された平型ケーブル１０には、何れの導線がどの部分に通っているかを判別したり、平型ケーブル１０の用途等を示すためにシース４０の表面に長手方向に沿って着色を施したり、刻印などを付加することができる。 In the created flat cable 10, it is possible to determine which portion of the lead wire passes through, or to color the surface of the sheath 40 along the longitudinal direction in order to indicate the use of the flat cable 10, etc. , Stamps and the like can be added.

上記構成の平型ケーブル１０について、図２及び図３に示すように、第１シース４７を第２シース４９に対して引っ張ると、シース４０は、凹部４２に形成された切断可能部４３で引き裂かれて分断する。たとえば、一方の手の指先を第１シース４７側から括れ部４１に入れ、他方の手の指先を第２シース４９側から括れ部４１に入れて引っ張ることで、切断可能部４３にてシース４０を容易に引き裂くことができる。 2 and 3, when the first sheath 47 is pulled with respect to the second sheath 49, the sheath 40 is torn by the cutable portion 43 formed in the recess 42, as shown in FIGS. Break up. For example, the fingertip of one hand is put into the constricted portion 41 from the first sheath 47 side, and the fingertip of the other hand is put into the constricted portion 41 from the second sheath 49 side and pulled, so that the sheath 40 can be cut by the cutable portion 43. Can be easily torn.

その結果、被覆第１導線２０を被覆するシース４０は、切断可能部４３間の被覆第２導線３０と連続する残留部４４を残して、被覆第１導線２０と共に引き剥がされることとなる。 As a result, the sheath 40 that covers the coated first conductive wire 20 is peeled off together with the coated first conductive wire 20, leaving a remaining portion 44 that is continuous with the coated second conductive wire 30 between the cutable portions 43.

残留部４４は、被覆第２導線３０側である第２シース４９に形成される。この残留部４４は、断面略台形状、略矩形形状又は略三角形形状であり、略台形形状又は略矩形形状の場合、残留部４４は、被覆第１導線２０と当接していた先端面は円弧状となる。 The remaining portion 44 is formed in the second sheath 49 on the coated second conducting wire 30 side. The residual portion 44 has a substantially trapezoidal cross section, a substantially rectangular shape, or a substantially triangular shape. In the case of the substantially trapezoidal shape or the substantially rectangular shape, the residual portion 44 has a circular end surface that is in contact with the covered first conductive wire 20. Arc shape.

残留部４４は、第２シース４９と一体であり、さらに、略台形形状又は矩形形状であるため見栄えが良く、この残留部４４を第２シース４９から除去する必要はない。 The remaining portion 44 is integrated with the second sheath 49 and has a substantially trapezoidal shape or rectangular shape, so that the remaining portion 44 has a good appearance, and it is not necessary to remove the remaining portion 44 from the second sheath 49.

残留部４４を第２シース４９に残して引き剥がされた被覆第１導線２０側の第１シース４７は、図２及び図３に示すように、残留部４４のあった部分が空隙４８となる断面略Ｃ字状に構成される。 As shown in FIGS. 2 and 3, the first sheath 47 on the side of the coated first conducting wire 20 that is peeled off while leaving the remaining portion 44 on the second sheath 49 becomes a gap 48 as shown in FIGS. 2 and 3. The cross section is substantially C-shaped.

切断可能部４３を上記したとおり、切断可能部４３の間隔を、被覆第１導線２０の直径よりも小さくすることで、第１シース４７に形成される空隙４８の幅を被覆第１導線２０の直径よりも小さくすることができる。従って、第１シース４７を引っ張ったときに、被覆第１導線２０が第１シース４７から外れることなく一体に第２シース４９から引き剥がすことができる。 As described above, the interval between the cutable portions 43 is made smaller than the diameter of the covered first conducting wire 20 to reduce the width of the gap 48 formed in the first sheath 47 of the covered first conducting wire 20. It can be made smaller than the diameter. Accordingly, when the first sheath 47 is pulled, the covered first conducting wire 20 can be integrally peeled from the second sheath 49 without being detached from the first sheath 47.

望ましくは、空隙４８の幅Ｗ（図３参照）は、最も狭い部分、たとえば、略台形形状の場合は内面側の幅が、被覆第１導線２０の直径の５％〜４０％となるようにする。空隙４８の幅Ｗが、被覆第１導線２０の直径の４０％を越えると、第１シース４７を引っ張ったときに、被覆第１導線２０が空隙４８からはみ出て、被覆第１導線２０が第１シース４７から外れてしまい、作業性が低下することがある。また、空隙４８の幅Ｗが、被覆第１導線２０の直径の５％よりも狭くなると、後述する被覆第１導線２０から第１シース４７を剥ぎ取る工程において、スムーズに第１シース４７を剥ぎ取ることができなくなるためである。 Desirably, the width W of the air gap 48 (see FIG. 3) is such that the narrowest portion, for example, in the case of a substantially trapezoidal shape, the width on the inner surface side is 5% to 40% of the diameter of the coated first conducting wire 20. To do. When the width W of the air gap 48 exceeds 40% of the diameter of the covered first conducting wire 20, when the first sheath 47 is pulled, the covered first conducting wire 20 protrudes from the air gap 48 and the covered first conducting wire 20 is 1 sheath 47 may come off and workability may be reduced. Further, when the width W of the air gap 48 becomes narrower than 5% of the diameter of the covered first conducting wire 20, the first sheath 47 is smoothly peeled off in the step of peeling the first sheath 47 from the covering first conducting wire 20 described later. It is because it becomes impossible to take.

すなわち、第１シース４７を第２シース４９から引き剥がすときに、第１シース４７が被覆第１導線２０とばらばらにならないから、作業性を可及的に向上させることができる。 In other words, when the first sheath 47 is peeled off from the second sheath 49, the first sheath 47 is not separated from the covered first conducting wire 20, so that workability can be improved as much as possible.

たとえば、必要長さだけ被覆第１導線２０を第１シース４７と共に引き剥がした後、被覆第１導線２０を掴んで、第１シース４７を図４の矢印Ａ方向に引っ張ると、第１シース４７は、空隙４８が広がって、被覆第１導線２０を引き出すことができる。 For example, after the coated first conducting wire 20 is peeled off together with the first sheath 47 by a necessary length, the first sheath 47 is grasped and pulled in the direction of arrow A in FIG. The gap 48 is widened, and the covered first conductive wire 20 can be pulled out.

その後、図４の一点鎖線Ｃで示すように、必要な長さ位置で第１シース４７を切断することで、被覆第１導線２０を露出させることができる。 Thereafter, as shown by the one-dot chain line C in FIG. 4, the first sheath 47 can be exposed at the required length position to expose the covered first conducting wire 20.

第１シース４７を切断する際に、必要長さよりも少し長めに第１シース４７を被覆第１導線２０から剥ぎ取って、必要長さ位置で切断した後、長めに剥ぎ取られた第１シース４７を被覆第１導線２０側に押し込めば、空隙４８が広がって被覆第１導線２０を越え、被覆第１導線２０を再度被覆することができる。従って、第１シース４７の切断の際に、被覆第１導線２０を傷付けることもないので、第１シース４７の切断も極めて容易に行なうことができる。 When the first sheath 47 is cut, the first sheath 47 is peeled off from the covered first conducting wire 20 slightly longer than the required length, cut at the required length position, and then the first sheath peeled off longer. If 47 is pushed into the coated first conductive wire 20 side, the gap 48 widens and exceeds the coated first conductive wire 20, and the coated first conductive wire 20 can be coated again. Therefore, the first sheath 47 can be cut very easily because the covered first conducting wire 20 is not damaged when the first sheath 47 is cut.

図５は、上記により得られた本発明の一実施形態に係る平型ケーブル１０の斜視図である。図に示すように、被覆第１導線２０は第１シース４７に被覆されているため、被覆第１導線２０をそのまま露出した状態で被覆第２導線３０側である第２シース４９に接着させた場合と比較して、平型ケーブル１０を工事する場合、被覆第１導線２０に対する直接的な擦過傷をなくすることができ、結果として、経年劣化等への耐性を非常に高めることができる。 FIG. 5 is a perspective view of the flat cable 10 according to one embodiment of the present invention obtained as described above. As shown in the figure, since the covered first conducting wire 20 is covered with the first sheath 47, it is adhered to the second sheath 49 on the covering second conducting wire 30 side with the covered first conducting wire 20 exposed as it is. Compared to the case, when constructing the flat cable 10, it is possible to eliminate direct scratching on the covered first conducting wire 20, and as a result, it is possible to greatly enhance the resistance against aging and the like.

加えて、第２シース４９に残った残留部４４は、断面略台形形状又は略矩形形状であるから、見栄えもよく、これを後から除去する必要もない。 In addition, since the remaining portion 44 remaining in the second sheath 49 has a substantially trapezoidal shape or a substantially rectangular shape in cross section, it looks good and does not need to be removed later.

上記のように、本発明の平型ケーブル１０によれば、シース４０によって一体化された被覆第１導線２０と被覆第２導線３０を容易に引き剥がすことができ、さらに、被覆第１導線２０を覆う第１シース４７も容易に取り除くことができるから、配線敷設作業の効率を可及的に高めることができる。 As described above, according to the flat cable 10 of the present invention, the coated first conductive wire 20 and the coated second conductive wire 30 integrated by the sheath 40 can be easily peeled off, and further, the coated first conductive wire 20. Since the first sheath 47 covering the wire can be easily removed, the efficiency of the wiring laying operation can be enhanced as much as possible.
