Description

【０００１】
【発明の属する技術分野】
本発明は、電磁波シールド編組用金属被覆糸とその糸で編組するスリーブに係わる。
【０００２】
【従来の技術】
従来から、ガスケット用や電線被覆用の電磁波（シールド）用スリーブとして用いられる電磁波シールド編組用スリーブは、糸の表面に電磁波シールド用の金属をメッキしたり、糸の表面に金属箔を巻き付けたりしたものが用いられている。
【０００３】
糸の表面に金属をメッキしたのでは、繰り返しの折曲げ等の機械的応力によって金属メッキが剥がれてしまい電磁波シールド効果がなくなることがある。
又、糸の表面全体に金属箔を巻き付けてしまうと、隣接する金属箔同士がこすれて、擦り切れたり破れたりすると共に、スリーブの可撓性、柔軟性が損なわれる。
【０００４】
これ等を解決するために、糸の表面に金属箔を隣接する金属箔と重ならない様に、間隔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ものが、実公平６−１１５９９号に示されている。
この公報においても、糸の表面に巻き付ける金属箔の隙間が狭いと金属箔が擦れて変形したり割れたりするし、隙間が広いとシールド効果が低下する。又、編組の際に、各糸に巻いた金属箔の角同士がひっかかったりして滑りにくいため金属箔が伸びたり、切れたりすることがある。
【０００５】
さらに、この公報記載のスリーブ内にコードを差し込むと、金属箔の角にコードの先がひっかかり金属箔を損傷するという問題もある。
【０００６】
【発明が解決しようとする課題】
そこで、本発明はシールド効果を犠牲にすることなく、使用中及び製造中に金属箔が損傷しないフレキシビリテイの高い電磁波シールド用の編組スリーブを提供する。
【０００７】
【課題を解決するための手段、発明の実施の形態及び発明の効果】
第１の発明は、繊維をより合わせた糸の表面に、金属箔を隣同士が重ならない様に隙間を設けて螺旋状に巻き付けた電磁波シールド編組用金属被覆糸において、前記金属箔同士の隙間から中の糸の細かい繊維をはみ出させたことを特徴とする。
【０００８】
具体的には、前記糸として、細かい繊維で表面を覆う様に毛ばだたせたものを使ったり、前記繊維を、多数の細かい単繊維（フィラメント）を集束より糸したマルチフィラメントヤーンにするとよい。
第１発明によると、金属箔同士の隙間から中の糸の細かい繊維をはみ出させてあるから、隙間を狭くしても隙間からはみだした細かい繊維が隙間に挟まり衝撃をやわらげるから金属箔同士が擦れたり損傷したりすることがない。
【０００９】
従って、金属箔を接近させて巻くことができ、シールド効果を上げることができる。
又、マルチフィラメントヤーンにアラミド繊維のを糸に用いると耐熱性に加え耐摩耗性に優れている。
【００１０】
尚、金属箔同士の隙間にはみだしている繊維が金属箔のエッジを保護するから金属被覆糸の滑りを円滑にすることができる。
第２の発明は、請求項１〜３のいずれか記載の電磁波シールド編組用金属被覆糸で合糸編組されたことを特徴とするスリーブである。
【００１１】
第２発明によると、第１の発明の作用効果の他に、スリーブ内にコードを差し込んだ際、コードの先端が金属箔の隙間からはみ出している細かい繊維に当接し滑らかに差し込むことかできて、金属箔のエッジにコードの先端が直接ひっかかる様なことがないから金属箔を損傷させることがない。
【００１２】
【実施例】
本発明の実施例を図に基づいて説明する。
電磁波シールド編組スリーブの製造には、図１（ａ），（ｂ）に示す様に２本の耐熱性のマルチフィラメント２，２をより合わせ、より合わせ目から細い繊維３をもやもやと毛ばだたせて出して糸１の表面を覆ったものを用いる。
【００１３】
次に、図１（ｃ），（ｄ）に示すように、幅：０．３３ｍｍ、厚さ：０．０２６ｍｍの銅箔の表面に厚さ：０．５μｍの以上の錫メッキを施してある箔帯１０を、糸１の表面にごく僅かの隙間１１をもたせて螺旋状に巻き付け、螺旋状に巻きつけた箔帯１０の隙間１１から細い繊維３をもやもやと出して金属被覆糸３０を構成する。
【００１４】
この様な金属被覆糸３０は、螺旋状に巻き付けられた箔帯１０の隙間から細い繊維３をもやもやと出してあるから、金属被覆糸３０を折曲げたりしても箔帯１０の隙間１１から出ている細い繊維３が箔帯同士に挟まれて、クッションの役目を果たしてくれるし、箔帯１０が擦れたり割れたりしない様に保護してくれる。
【００１５】
従って、箔帯１０を接近させてごく僅かの隙間１１を開けるだけで巻き付けることができるからシールド性を向上させることができる。
又、この金属被覆糸３０で編み込む時に金属被覆糸３０が多くの細い繊維３をもやもやと箔帯１０の隙間１１から出しているから、細い繊維３が箔帯１０の夫々のエッジを覆ってくれて滑り易いから途中で箔帯１０がひっかかって伸びたり切れたりすることがない。従って、編み込み易く、この手の編組用の金属被覆糸に適している。
【００１６】
図２（ａ）に示す様に金属被覆糸３０で３本×２４打でスリーブ４０を編み上げると電磁シールド編組スリーブが完成する。
この電磁シールド編組スリーブは、図２（ｂ）に示す様に金属被覆糸３０の箔帯１０の隙間１１から出ている細い繊維３がスリーブ４０の中側にも出ており、スリーブ４０の中側にコード等を差し込む際に、この細い繊維３が奥の方になびいてくれて箔帯１０のエッジを覆ってくれるからコード等の先端が箔帯１０にひっかかることがないし、箔帯１０を破ったりして損傷させることがない。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a metal-coated yarn for braiding an electromagnetic wave shield and a sleeve braided with the yarn.
[0002]
[Prior art]
Conventionally, an electromagnetic wave shielding braided sleeve used as an electromagnetic wave (shield) sleeve for a gasket or an electric wire covering has a metal for an electromagnetic wave shield plated on the surface of the yarn, or a metal foil wound on the surface of the yarn. Things are used.
[0003]
If a metal is plated on the surface of the yarn, the metal plating may peel off due to mechanical stress such as repeated bending, and the electromagnetic wave shielding effect may be lost.
In addition, when the metal foil is wound around the entire surface of the yarn, the adjacent metal foils are rubbed with each other, and are worn or broken, and the flexibility and flexibility of the sleeve are impaired.
[0004]
In order to solve these problems, it is necessary to wrap a plurality of yarns wound spirally at intervals so that the metal foil does not overlap with the adjacent metal foil on the surface of the yarn. No. 6-11599.
Also in this publication, if the gap between the metal foils wound around the surface of the yarn is narrow, the metal foil is rubbed and deformed or cracked, and if the gap is wide, the shielding effect is reduced. Further, at the time of braiding, the corners of the metal foil wound around each thread are stuck and are not slippery, so that the metal foil may be stretched or cut.
[0005]
Further, when the cord is inserted into the sleeve described in this publication, there is a problem that the tip of the cord is caught at a corner of the metal foil and the metal foil is damaged.
[0006]
[Problems to be solved by the invention]
Accordingly, the present invention provides a braided sleeve for electromagnetic wave shielding with high flexibility that does not damage the metal foil during use and manufacture without sacrificing the shielding effect.
[0007]
Means for Solving the Problems, Embodiments of the Invention and Effects of the Invention
According to a first aspect of the present invention, there is provided a metal-coated yarn for an electromagnetic shielding braid, wherein a metal foil is spirally wound on a surface of a yarn in which fibers are twisted so that adjacent metal foils do not overlap each other. It is characterized in that the fine fibers of the yarn inside are protruded.
[0008]
Specifically, it is preferable to use, as the yarn, a yarn that has been fluffed so as to cover the surface with fine fibers, or to use the fiber as a multifilament yarn in which a large number of fine single fibers (filaments) are twisted from a bundle.
According to the first invention, the fine fibers of the yarn inside are protruded from the gaps between the metal foils, so even if the gaps are narrowed, the fine fibers protruding from the gaps are caught in the gaps and soften the impact, so the metal foils are rubbed. No damage or damage.
[0009]
Therefore, the metal foil can be wound close to and the shielding effect can be improved.
When aramid fiber is used for the multifilament yarn, the abrasion resistance is excellent in addition to the heat resistance.
[0010]
Since the fibers protruding into the gaps between the metal foils protect the edges of the metal foil, the sliding of the metal-coated yarn can be made smooth.
According to a second aspect of the present invention, there is provided a sleeve characterized in that the metal-coated yarn for braiding an electromagnetic shield according to any one of claims 1 to 3 is braided.
[0011]
According to the second invention, in addition to the operation and effect of the first invention, when the cord is inserted into the sleeve, the tip of the cord can contact the fine fiber protruding from the gap of the metal foil and be smoothly inserted. Since the tip of the cord does not directly catch on the edge of the metal foil, the metal foil is not damaged.
[0012]
【Example】
An embodiment of the present invention will be described with reference to the drawings.
To manufacture an electromagnetic shielding braided sleeve, as shown in FIGS. 1A and 1B, two heat-resistant multifilaments 2 and 2 are twisted together, and a fine fiber 3 is smoky and fuzzy from the joint. A thread which is put out and covers the surface of the thread 1 is used.
[0013]
Next, as shown in FIGS. 1C and 1D, a copper foil having a width of 0.33 mm and a thickness of 0.026 mm is plated with tin having a thickness of 0.5 μm or more. The foil strip 10 is spirally wound around the surface of the yarn 1 with a very small gap 11, and the thin fiber 3 is misted from the gap 11 of the spirally wound foil strip 10 to form the metal-coated yarn 30. I do.
[0014]
Since such a metal-coated yarn 30 has a thin fiber 3 mist coming out of a gap between the spirally wound foil strips 10, even if the metal-coated thread 30 is bent, the thin fibers 3 are not removed from the gaps 11 of the foil strip 10. The thin fibers 3 are sandwiched between the foil strips to serve as a cushion and protect the foil strip 10 from being rubbed or broken.
[0015]
Therefore, the foil strip 10 can be wound by approaching the foil strip 10 and opening a very small gap 11, so that the shielding property can be improved.
Also, when the metal-coated yarn 30 is knitted with the metal-coated yarn 30, the metal-coated yarn 30 has a lot of fine fibers 3 coming out of the gaps 11 of the foil band 10 so that the fine fibers 3 cover the respective edges of the foil band 10. Since it is slippery, the foil strip 10 does not catch on the way and does not stretch or break. Therefore, it is easy to knit and is suitable for such a metal-coated yarn for braiding.
[0016]
As shown in FIG. 2 (a), when the sleeve 40 is knitted by 3 × 24 strokes with the metal-coated yarn 30, the electromagnetically shielded braided sleeve is completed.
In this electromagnetic shield braided sleeve, as shown in FIG. 2 (b), the thin fibers 3 coming out of the gaps 11 of the foil strips 10 of the metal-coated yarn 30 also come out on the inner side of the sleeve 40. When the cord or the like is inserted into the side, the thin fibers 3 move toward the back and cover the edge of the foil strip 10, so that the tip of the cord or the like does not catch on the foil strip 10, Does not break or damage.
