周辺に障害電波を吸収りる金網イ」の防護壁を設けて電
波の漏れを解消する手段が必要であった。A high-frequency generator generally used for drying wood generates an oscillating electric field and an oscillating magnetic field using an oscillating current, and these two mutually induce each other to generate electromagnetic waves. Therefore, when the high frequency generator is used, high noise is generated and causes electromagnetic interference in the surrounding area. For this reason, it was necessary to provide a protective wall of wire mesh around the generator to absorb interference radio waves to eliminate the leakage of radio waves.

定されている。Furthermore, since argon welding machines for welding stainless steel etc. use an AC power source, the arc is momentarily interrupted when the frequency pulse shifts to the negative side, so the arc is maintained continuously. In order to do this, the high frequency is set to be applied as this frequency pulse shifts to the negative side.

やカーラジオが電磁障害を受けることが多かった。This made it difficult to install a complete protective wall. Furthermore, in recent years, the electronicization of automobiles has been promoted and logic circuits are installed in important parts, and car radios have become widespread and are installed in most vehicles, but the spark discharge C1 in the vehicle engine is high. Noise is generated. As a result, the above circuits and car radios often suffered from electromagnetic interference.

Attempts have been made to form a protective wall by painting or vapor-depositing metal powder, but commercialization of both methods was postponed due to difficulties in uniformly distributing metal powder and high costs.

を提供することにある。The object of the present invention is to attach a plate-shaped thermoplastic resin to at least one surface of a plate-shaped mesh conductor, apply electricity to the conductor from the opposite end thereof, and generate heat in the conductor by the electricity supply. By pressing the conductor and the thermoplastic resin together, the two can be integrated, and interference radio waves can be uniformly and completely absorbed at low cost, and the molding conditions are good. Another object of the present invention is to provide a method for manufacturing an electric shield that can easily and reliably and safely produce a protective wall against electromagnetic interference using a planar body or a vertical body for cutting a magnetic box.

They are arranged so that they can be held at intervals. In this case, the shaft portions of the inner rollers 5 and 6 hold the thermoplastic resin plate 7 and the plate-like mesh conductor 8, which are sandwiched between the upper and lower sides, into the roller electric 4Jj1.
．． It is connected to a drive shaft (not shown) so that it can be conveyed synchronously with the feed rate of the plate-shaped wire conductor 8 according to 2.3.4.

Then, by mechanically applying a tensile force in the longitudinal direction, it is forcibly expanded to form a fixed length body (909n).
It is formed into a diamond-shaped mesh plate with a diameter of 1,818 mm.

nv, and the narrow area 10, which is arranged in a manner that intersects the wide area 9 and rfr, is approximately 5. They are each formed to have a size of nll+. Since the plate-like mesh conductor 8 has meshes forcibly formed on its surface by the above-mentioned mechanical force, the joints between the meshes are formed in an edge-like, sharply rising shape. The plate-like mesh conductor 8 has the function of smoothly absorbing interference radio waves, similar to a normal lath wire mesh. Note that the dimensions of the wide area section 9 and the narrow area section 1o are changed and set as appropriate to match the frequency of the interfering radio waves so that the radio waves do not leak through the mesh. Further, the rollers 5 and 5 are in vertical contact with the plate-like mesh conductor 8.
Thermoplastic resin plate 7 of the other material is sandwiched and pressed between 6
is 0.21111 due to synthetic resin materials such as vinyl chloride.
It is molded to a plate thickness of 11 mm. The width of this plate is approximately the same as the width of the rollers 5 and 6.

When both ends of the J-shaped mesh conductor 8 reach the positions of the left and right roller electrodes 1.2 and 3.4, both end surfaces of the mesh conductor 8 are held in contact between the top and bottom of both, so that during this time By applying the above voltage to the surface of the plate-like mesh conductor 8 (4), heat is generated in the humidity range (approximately 50°C to 55°C) where the contact surface of the heating QVI resin plate 7 is optimally softened. Under the thermal state, it advances to the 5 and 6 sides.

Ａの製造が完了できる。Both thermoplastic resin roots 7, which are conveyed in one direction and in contact with the upper and lower positions of the plate-like mesh conductor 8 which advances under the heated state described in F, conduction from the mesh conductor 8 in the intermediate zone. The contact surface becomes optimally soft when exposed to heat. At this time, both the resin plates 7 are subjected to a clamping pressure from the U-ra 5, 6 from above and below for 1 minute, so that both resin plates 7 on the softened side are The edge surface of the plate-like mesh conductor 8 bites into the surface portion of the plate-like mesh conductor 7. Therefore, the thermoplastic resin plate 7 and the plate-like mesh conductor 8 are integrated as a whole. As a result, when the product passes between the holding rollers 11, 12, 13, and 14, it becomes a series of regular-sized plate products, and the production of the electromagnetic shield A can be completed.

The thermoplastic resin plate 7 is brought into contact with the upper and lower positions of the mesh conductor 8, and by applying a voltage to the mesh conductor 8, heat is generated, thereby thermally bonding the thermoplastic resin plates 7 at the upper and lower positions. However, because of this, it can be manufactured later with uniform quality. In addition, since the above electromagnetic shield is manufactured with the plate-like conductor 8 exposed on both sides, for example, a plurality of the above electromagnetic shields A are arranged horizontally to form a wall surface that absorbs interference radio waves. case,
By combining these adjacent plate-like networks [1 conductor 8 comrades], a series of complete protective walls with no leakage of radio waves can be erected. Therefore, it has been extremely difficult to weld argon to a high-frequency generator to completely enclose the outer circumference of the place where the interference radio waves are generated, and to create a wall room that completely covers the area where radio waves are generated, at a low cost. It can be easily and quickly and completely remedied.

多大に貢献Ｃきるｂの（゛ある。As explained above, the present invention is as claimed in the claims.IJsI is applied to the electrodes on both sides to generate heat in the mesh conductor sandwiched therebetween, and conduction from the heat-generating mesh conductor. Since the mesh conductor and the resin material can be integrated using heat and a pressing force of 1" from the earth direction, the manufacturing equipment and manufacturing method are extremely simple. Therefore, an electromagnetic shielding body capable of completely absorbing interference radio waves with uniform quality can be manufactured easily, quickly, and reliably at low cost. This will greatly contribute to the development of this type of industry.
