Description

本発明は、電磁波の漏洩を防止する電磁シールド部材の接続構造に関する。   The present invention relates to a connection structure for an electromagnetic shield member that prevents leakage of electromagnetic waves.

従来の電磁シールドパネルにおいては、パネル相互の接続を簡易に行うことができ、作業工程を低減できるシールドパネル（特許文献１）や、シールドパネルを連設して壁や天井を構成した場合、シールドパネルの寸法公差等によって、シールドパネルの接合面に隙間を生じる虞があるため、この隙間を金属メッシュによって充填すること（特許文献２）が、一般的に知られている。   In the conventional electromagnetic shield panel, the panels can be easily connected to each other and the work process can be reduced (Patent Document 1). Since there is a possibility that a gap may be formed on the joint surface of the shield panel due to a dimensional tolerance of the panel or the like, it is generally known to fill this gap with a metal mesh (Patent Document 2).

特開平５−３７１７６号公報JP-A-5-37176 特開２００４−４４３８０号公報JP 2004-44380 A

しかし、このようなシールドパネル同士の接続を簡易に行う場合、作業工程を低減することは可能であるが、シールドパネルの接合面に隙間を生じる虞がある。反面、この接合面に生じる隙間を金属メッシュ等で充填する場合、作業工程が増加してしまうといった問題もある。   However, in the case where such shield panels are simply connected to each other, it is possible to reduce the work process, but there is a possibility that a gap is formed on the joint surface of the shield panel. On the other hand, when the gap generated on the joint surface is filled with a metal mesh or the like, there is a problem that the work process is increased.

そこで、本発明は、上記従来の問題点を解消し、電磁シールド部材同士の接続を簡易に行い、作業工程を低減するとともに、電磁シールド部材の接合面に生じる隙間を電磁波遮蔽材で確実に充填して高いシールド性も確保可能とする電磁シールド部材の接続構造を提供することにある。   Therefore, the present invention eliminates the above-mentioned conventional problems, easily connects the electromagnetic shielding members, reduces the work process, and reliably fills the gap generated on the joining surface of the electromagnetic shielding members with the electromagnetic shielding material. An object of the present invention is to provide an electromagnetic shielding member connection structure that can ensure high shielding properties.

以下、本発明の実施の形態を図面に基づいて説明する。
図１は、導電性を備えたシールドルームの組み立ての一例を示す説明図である。図２は、図１のＡ−Ａ線断面の拡大図である。図３は、シールドルームのコーナー部の説明図である。図４は、図３のＢ部を拡大した説明図である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory view showing an example of assembly of a shield room having conductivity. FIG. 2 is an enlarged view of a cross section taken along line AA of FIG. FIG. 3 is an explanatory diagram of a corner portion of the shield room. FIG. 4 is an explanatory diagram in which a portion B in FIG. 3 is enlarged.

シールドルーム１は、電磁波を遮蔽する電磁シールド部材である金属製のパネル２，２・・と、コーナー部に設置される柱部材である金属製のアングル２０，２０・・と、パネル２，２間及びパネル２とアングル２０との間に設けられる電磁波遮蔽材である導電性ガスケット３と、を用いて所定の空間を囲むように形成され、外部に磁気が漏れない構造となっている。   The shield room 1 includes metal panels 2, 2... That are electromagnetic shielding members that shield electromagnetic waves, and metal angles 20, 20,. It is formed so as to surround a predetermined space using a conductive gasket 3 that is an electromagnetic wave shielding material provided between the panel 2 and the angle 20, and has a structure in which magnetism does not leak to the outside.

パネル２は、図２に示すように、内部が中空の四角板で、一方の端面１３は鉛直方向の溝１５を有する凹状に形成され、他方の端面１２には鉛直方向に突条１４が突設されている。溝１５内には、断面を略長方形状とする導電性ガスケット３と、その導電性ガスケット３に隣接する押圧板としての板状の導電性ガスケット潰し材４とが収容され、溝１５の開口寄りには、孔部７及びネジ部８が、奥側にはネジ部９が夫々設けられて、ネジ部９に、先端がガスケット潰し材４に当接するネジ１７が螺合している。このネジ１７及びガスケット潰し材４とが本発明の押圧手段となる。   As shown in FIG. 2, the panel 2 is a square plate having a hollow inside, one end surface 13 is formed in a concave shape having a vertical groove 15, and the other end surface 12 has a protrusion 14 protruding in the vertical direction. It is installed. A conductive gasket 3 having a substantially rectangular cross section and a plate-shaped conductive gasket crushing material 4 as a pressing plate adjacent to the conductive gasket 3 are accommodated in the groove 15, and close to the opening of the groove 15. Are provided with a hole portion 7 and a screw portion 8, and a screw portion 9 is provided on the back side, and a screw 17 whose tip is in contact with the gasket crushing material 4 is screwed into the screw portion 9. The screw 17 and the gasket crushing material 4 are the pressing means of the present invention.

また、パネル２の突条１４は、溝１５の深さよりも短い寸法で突設されており、突条１４を隣接するパネル２の溝１５内に挿入して端面１２，１３同士を当接させた状態では、突条１４の先端面と溝１５の底面との間に、端面１２，１３同士が非接触となる空間２３が形成されるようになっている。
さらに、突条１４には、前述のように溝１５に挿入して端面１２，１３同士が当接した状態で、孔部７とネジ部８とに対応する位置に、孔部１０，１０が設けられている。よって、ネジ５を孔部７及び孔部１０，１０に貫通させてネジ部８に螺合させることで、隣接するパネル２，２同士を互いの端面１２，１３を当接させた状態で接続可能となっている。これが本発明の接続手段（ここではネジ止め手段）となる。
なお、パネル２における孔部７とネジ部９との対応位置には、ネジ５及び１７の操作用の孔部１１，１１が設けられて、各孔部１１には目隠し用の化粧キャップ６，６が嵌合されている。 Further, the protrusion 14 of the panel 2 is provided with a dimension shorter than the depth of the groove 15, and the end faces 12 and 13 are brought into contact with each other by inserting the protrusion 14 into the groove 15 of the adjacent panel 2. In this state, a space 23 in which the end surfaces 12 and 13 are not in contact with each other is formed between the tip surface of the protrusion 14 and the bottom surface of the groove 15.
Further, the ridge 14 has holes 10 and 10 at positions corresponding to the hole 7 and the screw portion 8 in a state where the end faces 12 and 13 are in contact with each other while being inserted into the groove 15 as described above. Is provided. Therefore, the adjacent panels 2 and 2 are connected to each other with their end faces 12 and 13 in contact with each other by passing the screw 5 through the hole 7 and the holes 10 and 10 and screwing them into the screw 8. It is possible. This is the connecting means (here, screwing means) of the present invention.
In the panel 2, holes 11 and 11 for operating the screws 5 and 17 are provided at positions corresponding to the holes 7 and the screw portions 9. 6 is fitted.

一方、シールドルーム１のコーナー部では、図３，４に示すように、アングル２０も内部が中空の四角柱で、平面視で隣接して互いに直交する２つの端面２１，２１には、パネル２と同様に孔部１０を備えた突条２２が鉛直方向に突設されて、夫々パネル２の溝１５に突条２２を挿入することで、端面２１がパネル２側の端面１３に当接してネジ５によるネジ止めが可能となっている。   On the other hand, at the corner portion of the shield room 1, as shown in FIGS. 3 and 4, the angle 20 is also a rectangular prism having a hollow inside, and the two end surfaces 21 and 21 that are adjacent to each other in plan view are orthogonal to each other. In the same manner as described above, the protrusion 22 having the hole 10 is provided in the vertical direction, and the protrusion 22 is inserted into the groove 15 of the panel 2 so that the end surface 21 comes into contact with the end surface 13 on the panel 2 side. Screwing with a screw 5 is possible.

以上の如く構成されたシールドルーム１の組み立ては、以下のように行われる。
まず、図２に示すように、パネル２の溝１５に導電性ガスケット３と、導電性ガスケット潰し材４とを挿入し、ネジ１７を孔部１１を介してネジ部９に螺合することで、仮止めを行う。そして、他のパネル２の突条１４を、端面１２が端面１３に当接する位置まで挿入し、ネジ５を孔部１１から孔部１０，１０を介してネジ部８に螺合する。これによって、パネル２，２同士が固定される。 The shield room 1 configured as described above is assembled as follows.
First, as shown in FIG. 2, the conductive gasket 3 and the conductive gasket crushing material 4 are inserted into the groove 15 of the panel 2, and the screw 17 is screwed into the screw portion 9 through the hole portion 11. , Temporarily fix. Then, the protrusion 14 of the other panel 2 is inserted to a position where the end surface 12 contacts the end surface 13, and the screw 5 is screwed into the screw portion 8 from the hole portion 11 through the hole portions 10 and 10. Thereby, the panels 2 and 2 are fixed.

その後、ネジ１７を仮止めの位置から更に奥へと締め込むことによって、導電性ガスケット３が導電性ガスケット潰し材４によって押圧される。これにより、導電性ガスケット３が弾性変形し、溝１５の底面及び側面１６と、突条１４の先端面とに隙間なく密接する。そして、化粧キャップ６，６を孔部１１，１１に嵌合し、孔部１１，１１・・の目隠しを行う。また、パネル２の残りの端部間に対しても、同様にネジ止めすると共に、導電性ガスケット３を弾性変形させてパネル２，２の端面間に当接させる。   Thereafter, the conductive gasket 3 is pressed by the conductive gasket crushing material 4 by tightening the screw 17 further from the temporarily fixed position. As a result, the conductive gasket 3 is elastically deformed, and is in close contact with the bottom surface and the side surface 16 of the groove 15 and the tip surface of the protrusion 14 without any gap. Then, the decorative caps 6 and 6 are fitted into the holes 11 and 11, and the holes 11, 11,. Further, the remaining end portions of the panel 2 are similarly screwed together, and the conductive gasket 3 is elastically deformed to be brought into contact between the end surfaces of the panels 2 and 2.

一方、コーナー部の組み立ては、図３に示すように、パネル２，２の溝１５に導電性ガスケット３と、導電性ガスケット潰し材４とを挿入し、ネジ１７を孔部１１を介してネジ部９に螺合することで仮止めを行い、アングル２０の各突条２２を、夫々端面２１が対応するパネル２の端面１３と当接するまで挿入し、ネジ５，５を孔部１１，１１・・から孔部１０，１０・・を介してネジ部８，８に螺合する。これにより、一対のパネル２，２がアングル２０に固定される。   On the other hand, as shown in FIG. 3, the corner portion is assembled by inserting the conductive gasket 3 and the conductive gasket crushing material 4 into the groove 15 of the panels 2 and 2 and screwing the screw 17 through the hole portion 11. The projections 22 of the angles 20 are temporarily fixed by being screwed to the portions 9 until the end surfaces 21 come into contact with the corresponding end surfaces 13 of the panel 2, and the screws 5, 5 are inserted into the holes 11, 11. .. screwed into the screw portions 8, 8 through the hole portions 10, 10,. As a result, the pair of panels 2 and 2 are fixed to the angle 20.

そして、ネジ１７，１７を仮止めの位置から更に奥へと締め込むことによって、導電性ガスケット３，３が導電性ガスケット潰し材４，４によって押圧される。これによって、導電性ガスケット３，３が弾性変形し、溝１５の底面及び側面１６と、突条２２の先端面とに隙間なく密着する。さらに、化粧キャップ６，６・・を孔部１１，１１・・に嵌合し、孔部１１，１１・・の目隠しを行う。
このように、パネル２，２同士を固定することと、パネル２，２とアングル２０とを固定することとによって、シールドルーム１が構成される。 Then, by tightening the screws 17 and 17 further from the temporarily fixed position, the conductive gaskets 3 and 3 are pressed by the conductive gasket crushing materials 4 and 4. As a result, the conductive gaskets 3 and 3 are elastically deformed, and are in close contact with the bottom surface and the side surface 16 of the groove 15 and the front end surface of the protrusion 22 without any gap. Further, the decorative caps 6, 6,... Are fitted into the holes 11, 11, and the holes 11, 11,.
In this way, the shield room 1 is configured by fixing the panels 2 and 2 and fixing the panels 2 and 2 and the angle 20.

以上のように、本形態の接続構造によれば、パネル２同士を互いの端面１２、１３を当接させた状態で接続する接続手段を設ける一方、端面１２，１３間の一部に、パネル２，２同士の接続状態で端面１２，１３同士が非接触となる空間２３を形成して、その空間２３内に、導電性ガスケット３と、その導電性ガスケット３を弾性変形させてパネル２の互いの端面（ここでは突条１４の先端面と溝１５の底面）に夫々当接させる押圧手段を設けたことで、パネル２，２間に形成した空間２３内で導電性ガスケット３が当接するため、シールド性が高く、電磁波の漏洩を確実に防止することができる。而も、パネル２，２間の端面同士の当接は維持されるため、シールドルーム１組立後の寸法精度が高く、設置スペースを必要以上に広く取る必要がない。さらに、導電性ガスケット３が露出しないため、汚損によるシールド性能の劣化も少ない。これはパネル２とアングル２０との接続についても同様である。   As described above, according to the connection structure of the present embodiment, the connection means for connecting the panels 2 with the end faces 12 and 13 in contact with each other is provided, while the panel between the end faces 12 and 13 is provided on a part. A space 23 is formed in which the end faces 12 and 13 are not in contact with each other in a connected state between the two and the two, and the conductive gasket 3 and the conductive gasket 3 are elastically deformed in the space 23 to form the panel 2. By providing pressing means for contacting each other's end surfaces (here, the tip surface of the protrusion 14 and the bottom surface of the groove 15), the conductive gasket 3 contacts in the space 23 formed between the panels 2 and 2. Therefore, the shielding property is high and leakage of electromagnetic waves can be reliably prevented. In addition, since the contact between the end surfaces of the panels 2 and 2 is maintained, the dimensional accuracy after the assembly of the shield room 1 is high, and it is not necessary to take a larger installation space than necessary. Furthermore, since the conductive gasket 3 is not exposed, there is little deterioration in the shielding performance due to contamination. The same applies to the connection between the panel 2 and the angle 20.

さらに、パネル２の何れか一方の端面１３を、溝１５を有する凹状に形成する一方、他方の端面１２に、パネル２，２同士の接続状態で溝１５に嵌合する突条１４を形成して、空間２３を溝１５の底面と突条１４の先端面との間に形成し、押圧手段による弾性変形で、導電性ガスケット３を溝１５の内面と突条１４の先端面とに夫々当接させるようにしたことで、導電性ガスケット３を露出させない状態でのパネル２、２同士の接続が簡単に行える。   Further, one end surface 13 of the panel 2 is formed in a concave shape having a groove 15, while the other end surface 12 is formed with a protrusion 14 that fits into the groove 15 in a connected state between the panels 2 and 2. Thus, the space 23 is formed between the bottom surface of the groove 15 and the tip surface of the ridge 14, and the conductive gasket 3 is applied to the inner surface of the groove 15 and the tip surface of the ridge 14 by elastic deformation by the pressing means, respectively. By making it contact, connection of the panels 2 and 2 in the state which does not expose the conductive gasket 3 can be performed easily.

また、接続されるパネル２は、内部が中空であって、接続手段は、嵌合した溝１５と突条１４とをパネル２の内部でネジ止めすることにある。さらに、押圧手段を、パネル２の厚み方向で導電性ガスケット３に対して移動可能に設けられた導電性ガスケット潰し材４と、パネル２に螺合して導電性ガスケット潰し材４を当該厚み方向で導電性ガスケット３側へネジ送り可能なネジ１７とから形成している。
その結果、上記に加えて、ドライバーのみでパネル２，２の接続と電磁波の遮蔽とが可能であり、接続に特別な金物や連結具等を必要とせず、組立も容易である。それに加え、施工現場で導電性テープ等の補助接続資材が不要なので、施工が容易である。他にも、施工に特別な電磁波の遮蔽技術や知識を必要としないから、誰でも容易に施工することもでき、工期の短縮や、コスト削減に貢献する。 The panel 2 to be connected is hollow inside, and the connecting means is to screw the fitted groove 15 and the protrusion 14 inside the panel 2. Furthermore, the pressing means is connected to the conductive gasket crushing material 4 movably with respect to the conductive gasket 3 in the thickness direction of the panel 2, and the conductive gasket crushing material 4 is screwed into the panel 2 so that the conductive gasket crushing material 4 And a screw 17 that can be screwed to the conductive gasket 3 side.
As a result, in addition to the above, it is possible to connect the panels 2 and 2 and shield electromagnetic waves with only a screwdriver, so that no special hardware or coupling tools are required for the connection, and assembly is easy. In addition, construction is easy because no auxiliary connection material such as conductive tape is required at the construction site. In addition, since no special electromagnetic shielding technology or knowledge is required for construction, anyone can easily perform construction, contributing to shortening the construction period and reducing costs.

なお、本発明の接続構造は、上記実施形態の態様に何ら制限されるものではなく、パネル２端部の形状、構造、配置等の構成を、本発明の趣旨を逸脱しない範囲で必要に応じて適宜変更することができる。   Note that the connection structure of the present invention is not limited to the aspect of the above embodiment, and the configuration of the shape, structure, arrangement, etc. of the panel 2 end portion is as required without departing from the spirit of the present invention. Can be changed as appropriate.

例えば、パネル２は、内部が中空のパネルを用いているが、必ずしも内部が中空である必要はなく、パネル２と他のパネル２の端面同士が当接するとともに、導電性ガスケット３によって、隙間なく密着させるものであれば適宜変更可能である。   For example, the panel 2 uses a panel having a hollow inside, but the inside does not necessarily have to be hollow. The end surfaces of the panel 2 and the other panel 2 are in contact with each other, and the conductive gasket 3 allows no gap. As long as it adheres, it can change suitably.

さらに、電磁シールド部材の端面の形状は、必ずしも凹状と突条とを採用する必要はなく、両端面同士が当接するとともに、両端面同士が非接触となる空間内に電磁波遮蔽材が押圧手段と共に収容されるものであれば、例えばパネルの端部を突条が厚み方向の一方側へ偏る平面視Ｌ字状にして、電磁波遮蔽材の収容空間を露出状態で形成したり、一方の突条をなくして平坦な端面と他方の溝との間に空間を形成したり等、適宜変更可能である。   Furthermore, the shape of the end face of the electromagnetic shield member does not necessarily need to adopt a concave shape and a ridge, and both end faces come into contact with each other, and the electromagnetic shielding material and the pressing means are in a space where both end faces are not in contact with each other. If it is accommodated, for example, the end of the panel is formed in an L shape in plan view in which the ridge is biased to one side in the thickness direction, and the accommodation space for the electromagnetic shielding material is formed in an exposed state, or one of the ridges It is possible to appropriately change such as eliminating the gap and forming a space between the flat end face and the other groove.

また、接続手段は、上記ネジ止め手段に限らず、端面同士が当接した状態で固定可能であれば、爪やプランジャを使用して係止することによって固定する構造に変更しても良い。
さらに、押圧手段も、必ずしも上記形態のように押圧板をネジ部材でネジ送りする機構を採用する必要はなく、例えば、ネジ部材に代えてコイルバネや板バネ等の弾性体を利用する等、電磁波遮蔽材を電磁シールド部材の端面間に隙間なく密着させるものであれば、適宜設計変更可能である。 Further, the connecting means is not limited to the above-described screwing means, and may be changed to a structure that is fixed by locking using a claw or a plunger as long as the connecting means can be fixed in a state where the end faces are in contact with each other.
Furthermore, the pressing means does not necessarily need to employ a mechanism for screw-feeding the pressing plate with a screw member as in the above embodiment. For example, an electromagnetic wave such as an elastic body such as a coil spring or a leaf spring is used instead of the screw member. The design can be changed as appropriate as long as the shielding material is brought into close contact between the end surfaces of the electromagnetic shielding member without any gap.
