Description
【考案の詳細な説明】 産業上の利用分野 本考案は、電磁波の受動的、能動的遮断を必要とする、
電線等に用いられる。[Detailed Description of the Invention] Industrial field of application The present invention requires passive and active interruption of electromagnetic waves,
Used for electric wires, etc.
従来の技術 従来、電磁波遮蔽（シールド効果）を必要とする電線に
は、シールド線を利用したり、金属箔テープを巻き付け
て対処した。2. Description of the Related Art Conventionally, an electric wire that requires electromagnetic wave shielding (shielding effect) has been dealt with by using a shield wire or winding a metal foil tape.
ところが、シールド線は、電線径ごとに用意する必要が
あり、可とう性、柔軟性にも乏しい。However, it is necessary to prepare a shielded wire for each wire diameter, and it lacks flexibility and flexibility.
また、例えば特願昭６０−８７１２に開示されるシール
ドテープや金属箔テープの場合は、作業者の熟練性に負
うところが大きく、作業性やシールド効果に劣る。Further, for example, in the case of the shield tape or the metal foil tape disclosed in Japanese Patent Application No. 60-8712, the skill of the operator is largely involved, and the workability and the shield effect are poor.
そこで、実願昭６１−１２０１１８に開示されるよう
な、モノフィラメント糸に金属の化学メッキを施した合
成繊維の倦縮加工糸を巻回してなる糸状を筒状に編組し
てなる電磁波シールド用電線被覆材が知られている。Therefore, as disclosed in Japanese Utility Model Application No. 61-120118, a wire for electromagnetic wave shielding, which is formed by braiding a filament-like thread, which is obtained by winding a crimped thread of a synthetic fiber obtained by chemically plating a metal on a monofilament thread, into a tubular shape. Dressings are known.
しかし、一般に合成繊維への化学メッキは金属の厚さに
乏しく、また、金属の被着体に対する密着力も不十分で
あり、例えば、繰り返して、折り曲げ等の機械的刺激
や、電線を何度も抜き差しする摩擦的刺激を与えた場
合、メッキが容易に割れたり、剥がれたりして、本発明
の目的とする、優れたシールド効果や耐久性を有する電
線等のシールド材料の提供は、達成不可能である。However, in general, the chemical plating on synthetic fibers is poor in the thickness of metal, and the adhesion of the metal to the adherend is also insufficient. When a frictional stimulus for inserting and removing is applied, the plating is easily cracked or peeled off, and it is not possible to achieve the object of the present invention to provide a shield material such as an electric wire having an excellent shield effect and durability. Is.
また、倦縮加工糸を用いているため、糸自身の直径が大
きくなり、電磁波シールド用電線被覆材として、優れた
シールド効果を得るために、密に編組する必要があるの
に対し、それが不可能となるなどの問題もみられた。Further, since the crimped yarn is used, the diameter of the yarn itself becomes large, and as a wire covering material for electromagnetic wave shielding, it is necessary to closely braid in order to obtain an excellent shielding effect. There were also problems such as being impossible.
更に、倦縮加工糸は、平面平滑性に乏しく、結果として
表面摩擦力が大きいために、電線の挿入が極めて困難で
あり、本発明の目的とする、作業性の向上は図れないと
いう問題もあった。Furthermore, since the crimped yarn has poor planar smoothness and consequently has a large surface frictional force, it is extremely difficult to insert an electric wire, and there is a problem that workability, which is an object of the present invention, cannot be improved. there were.
考案が解決しようとする課題 本考案は、以上の欠点を解決し、シールド効果はもちろ
んのこと、汎用性、可とう性、柔軟性そして作業性に優
れた電磁波シールド用スリーブを提供することを目的と
する。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention solves the above-mentioned drawbacks and aims to provide an electromagnetic wave shielding sleeve excellent in versatility, flexibility, flexibility and workability as well as shielding effect. And
課題を解決するための手段 従って本考案は、糸の表面に、 金属箔を隣接する金属箔と重ならないように、 隙間を空けて、 螺旋状に巻き付けた、 糸を複数本合糸したもので、 スリーブ状に編組した、 電磁波シールド用スリーブを提供する。Therefore, the present invention is a device in which a plurality of yarns are combined on the surface of a yarn, which are spirally wound with a gap so that the metal foil does not overlap the adjacent metal foil. Provide a sleeve for electromagnetic wave shielding, which is braided in a sleeve shape.
ここで、糸表面に金属箔を隣接する金属箔と重ならない
ように、隙間を空けて、螺旋状に巻き付けることを要件
とするのは、糸の表面全体に、金属箔を巻き付けてしま
うと、隣接する金属箔どおしがこすれて、可とう性、柔
軟性が得られないためである。Here, it is a requirement that the metal foil be wound spirally with a gap so that the metal foil does not overlap the adjacent metal foil on the yarn surface, if the metal foil is wrapped around the entire surface of the yarn, This is because the adjacent metal foils rub against each other and flexibility and flexibility cannot be obtained.
また、糸の表面全体が金属で覆われていると、繰り返し
ての折り曲げ等の機械的刺激により、応力が集中して、
金属箔が容易に破断してしまい、耐久性のあるシールド
効果が得られないためでもある。Also, if the entire surface of the thread is covered with metal, stress is concentrated due to mechanical stimuli such as repeated bending,
This is also because the metal foil is easily broken and a durable shield effect cannot be obtained.
更には、隣接する金属箔どうしが重ね合うことにより、
段差が生じ、表面平滑性に乏しくなり、電線の抜き差し
が困難になるという問題も生じるためである。一方、上
記の糸を複数本合糸し用いるのは、より可とう性の高
い、耐久性の優れた電磁波シールド用スリーブを提供す
るためである。Furthermore, by overlapping adjacent metal foils,
This is because there is a problem that a step occurs, the surface smoothness becomes poor, and it becomes difficult to insert and remove the electric wire. On the other hand, the reason why a plurality of the above-mentioned yarns are combined and used is to provide a sleeve for electromagnetic wave shield having higher flexibility and excellent durability.
すなわち、複数本合糸したものを用いることにより、応
力を緩和し、金属箔の断線を効果的に防止し、更に機械
的強度を増すためでもある。That is, by using a plurality of yarns that are combined, the stress is relaxed, the breakage of the metal foil is effectively prevented, and the mechanical strength is further increased.
作用 電磁波シールド用スリーブの素材として、糸の表面に、
金属箔を隣接する金属箔と重ならないよう、隙間を空け
て、螺旋状に巻き付けた複数糸を用いてスリーブ状に編
組したことにより、被電磁波遮蔽物、例えば電線を、か
かるスリーブの中にとおすだけで、短時間に確実に電磁
波からシールド処理することができた。Action As a material for the sleeve for electromagnetic shielding, on the surface of the thread,
The metal foil is braided in a sleeve shape by using a plurality of spirally wound threads so that the metal foil does not overlap the adjacent metal foil. Only by doing so, it was possible to reliably shield the electromagnetic waves in a short time.
その他、被電磁波遮蔽物の径、形状に対する汎用性を持
たすこともできた。In addition, it was possible to have versatility with respect to the diameter and shape of the electromagnetic wave shield.
