Shielding structure of electromagnetic waves for distribution line

The present invention relates to an electromagnetic wave shielding structure of a distribution line, and more particularly, the structure is simple and easy to install, and accordingly, the manufacturing cost and the installation cost are low, and in particular, the electromagnetic wave is not only smoothly blocked, It is related with electromagnetic shielding structure of distribution line where data transmission is more stable because there is no room for error due to heat. .

In general, a lot of cables such as power lines and communication lines are installed in apartment houses such as apartment complexes, which are usually wired to the basement floor of a building. In this case, if the cable is laid in the air, it is not only sag down due to its own load, but also there is a high possibility of being damaged by interference with other structures.

Therefore, generally, the structure which supports a cable by mounting the tray which accommodates the said cable to the hanger provided under the slab is used.

However, since these trays are open at the top, electromagnetic waves generated from cables carrying high voltages reach the residential area through the slab, which may adversely affect the human body and electronic devices, and are induced by high voltages flowing into the cables. Static electricity may accumulate in the tray, which may be a hazard to workers in maintenance, etc. Therefore, an electromagnetic shielding structure of a distribution line has been required.

In order to solve such a conventional problem, "a plurality of hangers (1) having a U-shaped upper end is buried vertically to the slab and the lower part is connected horizontally; a rectangular lower plate (11) and on both sides of the lower plate (11) It is provided with a vertically formed side plate 12, a bent portion 13 bent inwardly at both upper ends of the side plate 12, and a ground line 15 on one side of the side plate 12, A tray (10) for accommodating the cable (2); a rectangular frame (21), an acryl plate (22) installed inside the frame (21), and an upper layer of the acryl plate (22), each layer Into the plurality of copper mesh layer 23 interposed between the energization spacer 230, a pair of hinge holes (27) formed at both edges of the frame 21, and the copper mesh layer 23 of the one corner A plurality of rectangular shielding plates 20 having a ground hole 25 formed therein; It is formed on the opposite side of the gripping portion 31 and the screw hole 32 perforated in the upper portion to be coupled to the gripping portion 31 that can slide in the longitudinal direction, the screw 33 that can be fixed at a predetermined position A slider provided with a hinge hole 34 coupled to a hinge bolt 35 together with a hinge hole 27 of the shield plate 20, and a slider installed at even-numbered positions among a plurality of shield plates 20 contacting each other. A hinge shaft 28 for hinge-bonding the shielding plates 20 through the hinge holes 27 at odd positions among the plurality of shielding plates 20 that are in contact with each other; Electromagnetic shielding structure of a distribution line for a multi-family house including a ground line 14 interconnecting one side of the corner side of the copper mesh layer 23 and one side of the side plate 12. "Patent Registration 10-0646349 (2006.11. 23) has been disclosed.

In the conventional electromagnetic shielding structure of the distribution line, the shield plate 20 which is slid by the slider 30 while being folded by a plurality of hinge shafts 28 on the upper surface of the tray 10 is wrapped in the frame 21 acrylic It consists of a plate 22 and a plurality of copper mesh layer 23, a plurality of copper mesh layer 23 is interposed between the conduction spacer 230 therebetween to maintain the gap between the layers and the ground wire 24 It is to be connected, although the effect of blocking the electromagnetic waves generated from the cable (2) accommodated in the tray 10, the structure is complicated and not easy to drop, accordingly, the manufacturing cost is high, especially on a hot summer day There was a structural problem that causes an error in the case of data transmission cable because the heat generated in 2) is not properly released.
