(57) [Problem] To provide a new type of wire winding tape for electric wires, which can be industrially easily manufactured. SOLUTION: A winding tape for electric wires, characterized in that a fine embossing is applied to the surface of a synthetic resin film.
Description
【0001】[0001]
本考案は、600V級以下の低圧電線、特に単相三線式電線に使用される抑え 巻きテープに関する。 The present invention relates to a low-winding tape of 600V class or less, particularly to a winding tape used for a single-phase three-wire cable.
【0002】[0002]
600V級以下の低電圧で使用され、かつ周波数の高くない一般の商用周波数 領域で用いられる単相三線式電線は、例えば図3に示すように撚り線からなる導 体(1)を絶縁テープ(2)で被覆してなる三線を絶縁性の介在物(3)と共に抑えテ ープ(4)で巻き、さらに保護被覆樹脂シース(5)で被覆した構造を有する。 A single-phase three-wire electric wire that is used at a low voltage of 600 V class or less and that is used in a general commercial frequency region where the frequency is not high is, for example, as shown in FIG. It has a structure in which the three wires covered by 2) are wound with a tape (4) together with an insulating inclusion (3), and further covered with a protective coating resin sheath (5).
【0003】 抑え巻きテープ(4)は、電線断面の形状を円形にする役割および被覆樹脂の落 ち込み防止の目的で使用されるもので、その外装(シース)である保護被覆樹脂 (5)(例えば、ポリ塩化ビニル、ポリエチレン等)による被覆加工中に外装被膜 に気泡又はふくれが生じないように通気性の大きいテープ、例えば布テープ、不 織布テープ等が使用されている。しかし、これらの通気性テープはコストが高い 欠点を有する。最近、非通気性のテープでありながら、抑え巻きテープとしての 機能を果たす白点印刷ポリプロピレンテープが開発され実用化されている。これ は一軸延伸プロピレンフィルムの表面に白色インキを2.5g/m2グラビア印刷 し、図4に示すように10mm角当り80〜120ドット印刷したものである。[0003] The holding tape (4) is used for the purpose of making the cross section of the electric wire circular and for the purpose of preventing the coating resin from dropping. A tape having a high air permeability, such as a cloth tape or a non-woven cloth tape, is used so that air bubbles or blisters do not occur in the exterior coating during the coating process (for example, polyvinyl chloride, polyethylene, or the like). However, these breathable tapes have the disadvantage of being expensive. Recently, a white spot printed polypropylene tape that functions as a holding tape while being a non-breathable tape has been developed and put into practical use. In this method, 2.5 g / m 2 gravure printing of white ink was performed on the surface of a uniaxially stretched propylene film, and 80 to 120 dots were printed per 10 mm square as shown in FIG.
【0004】 ところで、この白点印刷ポリプロピレン抑え巻きテープは、重ね巻きしたとき に白点が樹脂被覆したときの電線内部の空気抜きのためのフィルム間に空隙を作 るために使用されているが、高速被覆の条件によっては空気が抜けず、ふくれの 原因となることがある。[0004] By the way, this white spot printed polypropylene suppressed winding tape is used to form a gap between films for bleeding air inside the electric wire when white spots are covered with a resin when wrapped and wound. Depending on the conditions of high-speed coating, air may not escape and cause blistering.
【0005】[0005]
本考案は、前述した点に鑑み、グラビア印刷によって合成樹脂フィルム表面に 斑点状のインキ層を設けずとも、単に合成樹脂フィルム表面に微細なエンボス加 工処理を施しただけで、実用に供し得る電線用抑え巻きテープを提供するために なされたものである。 In view of the above, the present invention can be put to practical use simply by applying a fine embossing process to the surface of a synthetic resin film without providing a spotted ink layer on the surface of the synthetic resin film by gravure printing. This was done to provide a wire winding tape.
【0006】[0006]
本考案の電線用抑え巻きテープは、合成樹脂フィルム表面に全体に亘って微細 なエンボス加工を施し、重ね巻きしたときのフィルム間の空気抜けを容易にした ことを特徴としている。 The winding tape for electric wires of the present invention is characterized in that the surface of the synthetic resin film is finely embossed over the entire surface to facilitate air bleeding between the films when wrapped and wound.
【0007】[0007]
本考案によれば、エンボスパターンが流れ方向に対して各方向に入っているこ とから、重ね巻きを行ってもエンボスの山と谷が一致せず、空気抜きの間隙が容 易にできる。 According to the present invention, since the embossed pattern is in each direction with respect to the flow direction, the ridges and valleys of the emboss do not coincide even when lap winding is performed, and the gap for air venting can be easily performed.
【0008】[0008]
以下、本考案を図面に示す実施例により説明する。 Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.
【0009】 図1は厚さ20μmのポリプロピレンフィルムの表面にエンボス加工処理して 得られた厚さ23μmの抑えテープの斜視図を示し、図2は図1のA−A、B− Bの概略断面図である。FIG. 1 is a perspective view of a 23 μm-thick holding tape obtained by embossing the surface of a 20 μm-thick polypropylene film, and FIG. 2 is a schematic view of AA and BB in FIG. It is sectional drawing.
【0010】 エンボス加工を施した合成樹脂フィルムは所定の巾にスリットして目的とする 電線用抑え巻きテープに供する。[0010] The embossed synthetic resin film is slit into a predetermined width to be used as an intended wire winding tape.
【0011】 本考案に係る抑え巻きテープの基材として使用される合成樹脂フィルムは、耐 熱性、引張強度、伸び等の点から厚さ12〜125mμのポリプロピレンフィル ム、ポリエチレンテレフタレートフィルム、ナイロンフィルム、ポリエチレンフ ィルム等が好適である。The synthetic resin film used as the base material of the holding tape according to the present invention is a polypropylene film having a thickness of 12 to 125 mμ, a polyethylene terephthalate film, a nylon film, or the like in view of heat resistance, tensile strength, elongation, and the like. Polyethylene films and the like are preferred.
【0012】 エンボス加工は常法に従ってロールエンボス、平判エンボス等によって行うこ とができ、これによって膜厚が全体として14〜165μm、好ましくは24〜 70μm程度なる範囲内から適宜設定される。フィルム表面に形成するエンボス 模様は前述したように外装の保護被膜樹脂がコーティング処理を施したときに気 泡が残留しないように円滑な脱気作用をもたらすように設けるものであるから、 微細な山状、波状、格子状、絹目、皮しぼ、布目、菱目、水玉、円形、楕円形等 要するに表面平滑性のないものであればよい。The embossing can be carried out by roll embossing, plain embossing or the like according to a conventional method, whereby the film thickness is appropriately set within a range of about 14 to 165 μm, preferably about 24 to 70 μm as a whole. As described above, the embossed pattern formed on the film surface is provided so as to provide a smooth deaeration effect so that no bubbles remain when the protective coating resin of the exterior is subjected to the coating treatment. Shape, wavy, lattice, silk, grain, cloth, diamond, polka dot, round, oval, etc. In short, any material having no surface smoothness may be used.
【0013】 次に図1に示したエンボス加工ポリプロピレンテープで抑え巻きした単相三線 式電線にポリ塩化ビニル保護被膜を行ったところ、脱気不良による電線のふくれ は皆無であった。Next, when a polyvinyl chloride protective coating was applied to the single-phase three-wire electric wire held down and wound with the embossed polypropylene tape shown in FIG. 1, there was no bulging of the electric wire due to poor degassing.
【0014】[0014]
以上説明したように本考案によれば抑え巻きテープに形成したエンボスがフィ ルム間の空隙を形成するため、外装の保護被膜材料によるコーティング処理は効 率よく行うことができ、外装被膜にあわやふくれのない、外観上美麗な電線に仕 上げることができる。 As described above, according to the present invention, the embossing formed on the holding tape forms the gap between the films, so that the coating treatment with the protective coating material of the exterior can be performed efficiently, and the outer coating has a blister and blister. It is possible to finish the wire with no appearance and beautiful appearance.
