Description
本発明は、電磁波シールド性能を有するスライドファスナー及びそれを用いた電磁波シールド装置に関する。
特にスライド耐久性に優れるスライドファスナー及びこれを開閉部に設けた電磁波が遮蔽されたボックス，テント，計測施設等に係る。
The present invention relates to a slide fastener having electromagnetic shielding performance and an electromagnetic shielding device using the slide fastener.
In particular, it relates to slide fasteners with excellent sliding durability, and electromagnetic wave-shielded boxes, tents, measurement facilities, etc. that are provided in the opening and closing parts of the slide fasteners.
電子機器の開発分野では、電磁波によるノイズ対策、通信機器の通信性能テスト等、機器の開発段階にて電磁波がシールドされた測定空間が必要となる。
近年は、電気自動車の開発段階にて、大型の電磁波シールド施設が必要になっている。
これらの電磁波シールド空間に対して、電子機器や測定器の出し入れや、研究者等が出入りするための開閉部が必要となる。
このような開閉部を形成する手段として、スライドファスナーを採用することがある。
この場合に、金属製のエレメントを電磁波シールド性を有するテープ材（シート材）に連結することになるが、これまでに採用されている電磁波シールド性シート材としては、例えば特許文献１示すように、繊維シートに無電解メッキや電気メッキ等により、金属メッキにて被覆するものであった。
しかし、これではスライダーの開閉時にこのスライダーがメッキ層に摺接するためにメッキ層が剥離しやすく、また繊維シートが擦れることで破れが生じやすく、ファスナーのスライド耐久性に劣る技術的課題があった。
また、メッキ被覆繊維では金属量が少ないため、電磁波シールド性能が不充分である問題もあった。
In the field of electronic device development, a measurement space shielded from electromagnetic waves is required during the development stage of the device, such as noise countermeasures against electromagnetic waves and communication performance tests of communication devices.
In recent years, large-scale electromagnetic shielding facilities have become necessary during the development stage of electric vehicles.
These electromagnetic shielded spaces require openings and closing sections for the insertion and removal of electronic equipment and measuring instruments, as well as the access of researchers and others.
A slide fastener is sometimes used as a means for forming such an opening/closing part.
In this case, the metal element is connected to a tape material (sheet material) having electromagnetic shielding properties, and the electromagnetic shielding sheet materials that have been used so far include, for example, as shown in Patent Document 1. , the fiber sheet was coated with metal plating by electroless plating, electroplating, etc.
However, with this, the slider comes into sliding contact with the plating layer when the slider is opened and closed, which causes the plating layer to easily peel off, and the fiber sheet to rub against it, making it easy to tear, resulting in poor sliding durability of the fastener. .
Furthermore, since the amount of metal in plated coated fibers is small, there is also the problem that electromagnetic shielding performance is insufficient.
本発明は、開閉耐久性に優れるとともに、電磁波シールド性能の高い電磁波シールドスライドファスナー及びそれを用いた装置の提供を目的とする。 An object of the present invention is to provide an electromagnetic shielding slide fastener having excellent opening/closing durability and high electromagnetic shielding performance, and a device using the same.
本発明に係る電磁波シールドスライドファスナーは、左右一対の電磁波シールドテープと、前記一対の電磁波シールドテープの端部に相互に対向配置した複数の金属製のエレメントと、前記相互に対向配置した複数のエレメント同士を係合及び離脱するスライダーとを有し、前記エレメントは前記スライダーの摺接部と、前記摺接部に対して段差部を介して設けた係合部とを有することで前記スライダーが前記電磁波シールドテープに摺接しないようになっていることを特徴とする。
これにより、スライダーが電磁波シールドテープに摺接せず、テープの劣化を抑え、性能低下が生じない。
The electromagnetic shielding slide fastener according to the present invention includes a pair of left and right electromagnetic shielding tapes, a plurality of metal elements arranged opposite to each other at the ends of the pair of electromagnetic shielding tapes, and a plurality of elements arranged opposite to each other. and a slider that engages and disengages the elements, and the element has a sliding contact portion of the slider and an engaging portion provided through a stepped portion with respect to the sliding contact portion, so that the slider It is characterized in that it does not come into sliding contact with the electromagnetic shielding tape.
As a result, the slider does not come into sliding contact with the electromagnetic shielding tape, suppressing tape deterioration and preventing performance deterioration.
ここで、エレメントの摺接部と係合部とが段差部を介して有するとは、少なくとも二段形状になっていて、相互に対向配置した複数のエレメント同士が係合する際には、スライダーが両側のエレメント同士が接近する方向に相互にスライド押圧することになるが、本発明に係るエレメントは、この段差部を介して両側から押圧するとともに、スライダーは一段目の摺接部の上面に沿ってスライドすることで、スライダーがテープ生地の表面に当接しないようにしたものである。
これにより、テープ生地の表面がスライダーにより擦れることがなくなり、生地表面の導電性及び劣化耐久性が確保できる。
Here, having the sliding contact part and the engaging part of the element via a stepped part means that the sliding part and the engaging part of the element have at least a two-step shape, and when a plurality of elements arranged facing each other engage with each other, the slider The elements on both sides slide and press against each other in the direction in which they approach each other, but the element according to the present invention presses from both sides via this stepped portion, and the slider presses against the top surface of the first sliding contact portion. By sliding along the tape, the slider is prevented from coming into contact with the surface of the tape fabric.
This prevents the surface of the tape fabric from being rubbed by the slider, ensuring electrical conductivity and durability against deterioration of the fabric surface.
本発明において、電磁波シールドテープは樹脂繊維糸に金属箔糸を巻着してあってもよい。
例えば、ポリエステル等の各種繊維にアルミ箔や銅箔等の薄い箔を帯状に細く裁断した箔糸を螺旋状に巻き付けた繊維を織り込んで製造したテープ生地を採用するとよい。
電磁波シールド性能は表面抵抗及び遮蔽材質量の影響を受ける。
メッキ繊維や金属含浸繊維に比べると、金属箔を使用することにより表面抵抗が下がり、金属量が増え、その分電磁波シールド性能が向上する。
また、箔の両側のエッジによるコロナ放電効果により、従来のメッキ被覆繊維よりも表面抵抗が低く、電磁波シールド性能に優れる。
In the present invention, the electromagnetic shielding tape may include a metal foil thread wrapped around a resin fiber thread.
For example, a tape fabric manufactured by weaving various fibers such as polyester with fibers made by winding foil threads made by cutting thin foils such as aluminum foil or copper foil into strips in a spiral manner may be used.
Electromagnetic shielding performance is affected by surface resistance and the mass of the shielding material.
Compared to plated fibers or metal-impregnated fibers, the use of metal foil lowers the surface resistance and increases the amount of metal, which improves electromagnetic shielding performance.
In addition, due to the corona discharge effect created by the edges on both sides of the foil, the surface resistance is lower than that of conventional plated fibers, and it has excellent electromagnetic shielding performance.
本発明において、電磁波シールドテープと前記エレメントの連結部は金属糸を用いて編んであってもよい。
エレメントとテープとの連結部は、強度が必要であるとともに、その部分から電磁波が濡れるのを防ぐ必要がある。
そこで、上記連結部は細い銅線等を編んだものがよいが、金属糸を直接編むのが難しい場合には、水溶性の樹脂等で被覆した金属糸を編んだ後に樹脂層を除去してもよい。
In the present invention, the connecting portion between the electromagnetic shielding tape and the element may be knitted using metal thread.
The connecting portion between the element and the tape needs to have strength, and it is also necessary to prevent electromagnetic waves from getting wet from that portion.
Therefore, it is best to make the above connection part by knitting thin copper wires, etc. However, if it is difficult to knit the metal threads directly, remove the resin layer after knitting the metal threads coated with water-soluble resin etc. Good too.
本発明に係る電磁波シールドスライドファスナーを用いることで、開閉部の耐久性に優れるとともにシールド性能の高い電磁波シールドボックス，電磁波シールドテントを製作したり、シールド性の高い測定室等の建築物を製作することもできる。
また、生地の接合部としても使用でき、大型テント等の場合に生地同士をファスナーで繋ぐことで、サイズの変更ができる。
なお、大型の場合に強度を上げる目的で芯糸にアラミド系の高強度繊維を使用してもよい。
By using the electromagnetic shielding slide fastener according to the present invention, it is possible to manufacture electromagnetic shielding boxes and tents that have excellent durability in opening and closing parts and have high shielding performance, and to manufacture buildings such as measurement rooms with high shielding performance. You can also do that.
It can also be used as a joint between fabrics, and in the case of large tents, the size can be changed by connecting the fabrics with a zipper.
In addition, in the case of a large size, high-strength aramid fibers may be used for the core thread in order to increase the strength.
本発明に係るスライドファスナーは、開閉時にスライダーがテープ生地に直接触れないので、テープ生地の表面の擦れや傷付きを防止するので、開閉耐久性に優れる。
また、テープ生地に金属箔糸を巻着した繊維糸を用いたので、シールド性能も向上する。
The slide fastener according to the present invention has excellent opening and closing durability because the slider does not directly touch the tape fabric during opening and closing, thereby preventing the surface of the tape fabric from being rubbed or damaged.
Furthermore, since the tape fabric is made of fiber yarn wrapped with metal foil yarn, shielding performance is also improved.
