<p>Disclosed are a polyhedron type electromagnetic shielding device having an electromagnetic field absorption effect and an electromagnetic shielding apparatus having the same. The polyhedron type electromagnetic shielding device having an electromagnetic field absorption effect is a shielding device connected to a terminal polarity fixing unit and applying any one among a neutral power supply and a phase voltage power supply to a designated terminal and the other one to another designated terminal. The polyhedron type electromagnetic shielding device comprises: a first conductor which always receives the neutral power supply, regardless of which power supply, among the neutral power supply and the phase voltage power supply, is connected to which terminal; and a second conductor which receives the phase power supply regardless of which power supply, among the neutral power supply and the phase voltage power supply is connected to which terminal, wherein the first conductor is formed to be surrounded by the second conductor having a polyhedron form. Accordingly, since additional efforts are not needed to find a neutral terminal, user convenience is increased. Since grounding through the neutral terminal is enabled, occurrences of electric shock accidents caused by a non-expert or a non-cognizer can be reduced. Since exposure to an electromagnetic wave arising from a zero-potential phenomenon is reduced, effects to the human body can be minimized, and reduction in the damage to the human body resulting from electromagnetic wave shielding can be obtained by using another electronic device or electrical device in parallel, without replacing the electronic device or electrical device.</p> |
