Abstract
Description
本発明は、電磁波遮蔽性能を有するファスナー構造に関する。 The present invention relates to a fastener structure having electromagnetic wave shielding performance.
電子機器や医療機器を持ち運ぶ際に、電磁波の影響を受けないように電磁波遮蔽ボックスを用いたり、簡易電波測定用に電磁波シールドテントを用いたり、あるいは電磁波の影響を受けないように仕切った研究開発現場を設けることがある。
このような場合に、電磁波に対してシールド効果を有する導電性のボックス，容器，テント，仕切布等が用いられているが、機器の出し入れや人の出入りが可能になるように、開閉自在のスライドファスナーが採用されている場合がある。
しかし、スライドファスナーは、左右一対のテープの端部に複数のエレメントを相互に配置し、この左右のエレメントの務歯頭部同士の噛み合せをスライダーで開閉する構造になっているために、このエレメントの噛合部から電磁波が漏れる問題があった。
When carrying electronic or medical equipment, use an electromagnetic shielding box to prevent it from being affected by electromagnetic waves, use an electromagnetic shielding tent for simple radio wave measurements, or partition R&D so that it is not affected by electromagnetic waves. A site may be set up.
In such a case, a conductive box, container, tent, partition cloth or the like having a shielding effect against electromagnetic waves is used, but it can be opened and closed freely so that equipment can be taken in and out and people can go in and out. Slide fasteners may be used.
However, the slide fastener has a structure in which a plurality of elements are mutually arranged at the end portions of a pair of left and right tapes, and the engagement between the coupling tooth heads of the left and right elements is opened and closed by a slider. There was a problem that electromagnetic waves leaked from the meshing part of.
例えば特許文献１には、２つのファスナーを平行にずれた位置に設けた磁気遮蔽装置を開示する。
しかし、２つのファスナーを単に重ね合せた構造にあっては、エレメントの開閉線が左右にずれていたとしても、電磁波は上下の開閉線をいわば斜めに漏れるので、そのシールド効果が不充分であった。
特許文献２には、面ファスナーを重ね合せてシールド用チューブを形成する技術を開示するが、面ファスナーの重ね合せでは開閉操作が大変である。
For example, Patent Document 1 discloses a magnetic shield device in which two fasteners are provided at positions displaced in parallel.
However, in the structure in which two fasteners are simply overlapped, even if the opening/closing line of the element is shifted to the left or right, the electromagnetic wave leaks diagonally from above and below the opening/closing line, so the shielding effect is insufficient. It was
Patent Document 2 discloses a technique of forming a shield tube by stacking surface fasteners, but opening and closing operations are difficult when stacking surface fasteners.
本発明は、電磁波のシールド性能の向上を図るのに有効なファスナー構造の提供を目的とする。 It is an object of the present invention to provide a fastener structure effective for improving the electromagnetic wave shielding performance.
本発明に係る電磁波遮蔽ファスナー構造は、第１スライドファスナーと第２スライドファスナーとを二重に備え、前記第１スライドファスナーの第１開閉線と、前記第２スライドファスナーの第２開閉線とが平行で且つ左右に位置をずらして配置されているとともに、前記第１スライドファスナーと第２スライドファスナーとの間に帯状の電磁波遮蔽片を有することを特徴とする。
ここで、スライドファスナーは開閉にスライダーを用いたものであれば、ファスナー構造に制限はない。
An electromagnetic wave shielding fastener structure according to the present invention includes a first slide fastener and a second slide fastener in a dual manner, and a first opening/closing line of the first slide fastener and a second opening/closing line of the second slide fastener are provided. The invention is characterized in that they are arranged parallel to each other and shifted in the left and right directions, and that a strip-shaped electromagnetic wave shielding piece is provided between the first slide fastener and the second slide fastener.
Here, the slide fastener is not limited to a fastener structure as long as it uses a slider for opening and closing.
ここで、帯状の電磁波遮蔽片は左右一対の第１電磁波遮蔽片と第２電磁波遮蔽片とからなり、スライドファスナーを閉じた状態では前記第１及び第２電磁波遮蔽片が相互に一部重なるものであるのが、さらに好ましい。
この場合には、第１電磁波遮蔽片を左右一対のテープのうち、一方のテープ側に設け、第２電磁波遮蔽片を他のテープ側に設けることになる。
Here, the strip-shaped electromagnetic wave shielding piece is composed of a pair of left and right first electromagnetic wave shielding pieces and second electromagnetic wave shielding pieces, and the first and second electromagnetic wave shielding pieces partially overlap each other when the slide fastener is closed. Is more preferable.
In this case, the first electromagnetic wave shielding piece is provided on one tape side of the pair of left and right tapes, and the second electromagnetic wave shielding piece is provided on the other tape side.
本発明に係るファスナー構造にあっては、２つのスライドファスナーを平行で且つ、位置がずれるように二重に配置するとともに、その間に電磁波遮蔽片を設けたので、電磁波のシールド効果に優れる。
また、ファスナーとして、スライダーで開閉できるスライドファスナーを採用したことにより、従来の面ファスナーの重ね合せ構造に比較して、開閉操作が容易である。
In the fastener structure according to the present invention, the two slide fasteners are arranged in parallel and doubly displaced so that the electromagnetic wave shielding piece is provided between them, so that the electromagnetic wave shielding effect is excellent.
Further, by adopting a slide fastener that can be opened and closed with a slider as the fastener, the opening and closing operation is easier as compared with the conventional superposed structure of surface fasteners.

その測定結果を図８の表に示す。
発信器から発生する電磁波の強度に対して、外側にどれだけ下がったかを測定（単位ｄｂ）した。
本発明品は実施例２に相当し、従来品は平行で位置をずらした二重ファスナーの場合である。
測定周波数２．４ＧＨｚでは、従来品が−７２ｄｂであったのに対して、本発明品はシールド効果が大きく、計測できない状態であった（計測不可）。
測定周波数５ＧＨｚにおいては、従来品が−７０ｄｂであったのに対して、本発明品はそれよりもシールド効果が大きい−９２ｄｂであった。
これにより、本発明品は、従来品よりもシールド効果が高いことが確認できた。
The shield effects of the slide fastener structure according to the present invention and the conventional double fastener structure were measured comparatively and will be described below.
As shown in FIG. 7(a), a transmitter is placed in a bag body having an opening formed by a slide fastener, the slide fastener is closed, and as shown in FIG. 7(b), the intensity of electromagnetic waves leaked to the outside is adjusted. It was measured.
The measurement results are shown in the table of FIG.
With respect to the intensity of the electromagnetic wave generated from the transmitter, how much it went down was measured (unit: db).
The product of the present invention corresponds to the second embodiment, and the conventional product is a case of a double fastener which is parallel and displaced.
At a measurement frequency of 2.4 GHz, the product of the present invention had a large shielding effect, whereas the conventional product had a value of −72 dB, and could not be measured (measurement impossible).
At the measurement frequency of 5 GHz, the conventional product had -70 db, whereas the product of the present invention had -92 db, which had a greater shield effect.
From this, it was confirmed that the product of the present invention has a higher shielding effect than the conventional product.
本発明に用いる第１電磁波遮蔽片３０や第２電磁波遮蔽片４０は、位置をずらして配置した二重のスライドファスナーの間を塞ぐようにするのが目的である。
そこで、第１及び第２電磁波遮蔽片は厚みを有すると、それだけ遮蔽効果が高くなる。
例えば、遮蔽片を二重にしたり、袋状にし、その中にスポンジシート等の弾性材を挿入してもよい。
また、遮蔽片にスポンジシート等を貼り合せてもよい。
The purpose of the first electromagnetic wave shielding piece 30 and the second electromagnetic wave shielding piece 40 used in the present invention is to close the space between the double slide fasteners arranged at different positions.
Therefore, if the first and second electromagnetic wave shielding pieces have a thickness, the shielding effect becomes higher accordingly.
For example, the shielding piece may be doubled or formed into a bag shape, and an elastic material such as a sponge sheet may be inserted therein.
Further, a sponge sheet or the like may be attached to the shield piece.
