Electromagnetic shielding body and electromagnetic shielding structure utilizing same

A magnetic shielding room defined by a wall structure, said wall structure being comprised of a plurality of wall elements each being electrically connected and each being composed of at least one electromagnetic shielding panel which comprises:

• at least one ferromagnetic member formed in a shape of a panel;
• an electric conducting member formed in a shape of a panel and disposed substantially in parallel to the ferromagnetic member;
• and
• an electric connecting member electrically integrated with the electric conducting member, said electric connecting member being formed along an edge portion of the electric conducting member,
• wherein at least one of said wall elements is provided with an electromagnetic shielding exit/entrance structure which includes
• an electromagnetic shielding panel including at least one ferromagnetic member formed in a shape of a panel having a cutout portion forming a first opening, said first opening defining an edge portion, an electric conducting member formed in a shape of a panel and disposed substantially in parallel to the ferromagnetic member, said electric conducting member having an opening with a size corresponding to said first opening of the ferromagnetic member, and an electric connecting member electrically integrated with the electric conducting member, said electric connecting member being formed along an edge portion of the electric conducting member, and
• an electromagnetic shielding door member including at least one ferromagnetic member formed in a shape of a panel having a size larger than that of said first opening of the ferromagnetic member of said electromagnetic shielding panel, an electric conducting member formed in a shape of a panel and disposed substantially in parallel to the ferromagnetic member, and an electric connecting member electrically integrated with the electric conducting member, said electric connecting member being formed along an edge portion of the electric conducting member,
• wherein said electromagnetic shielding door member is fitted within the first opening of said electromagnetic shielding panel to be slidable so as to open or close the first opening, and
• wherein the electric connecting member of the electromagnetic shielding panel contacts the electric connecting member of the electromagnetic shielding door member when the electromagnetic shielding door member closes the first opening of the electromagnetic shielding panel.

An electromagnetic shielding panel adapted to be connected to at least a second electromagnetic shielding panel, comprising:

• a first ferromagnetic member;
• two second ferromagnetic members respectively disposed on either side of the first ferromagnetic member substantially in parallel to said first ferromagnetic member with spaces therebetween, wherein said second ferromagnetic members have a magnetic permeability smaller than that of said first ferromagnetic member;
• first and second electric conducting members, with said first electric conducting member disposed between said first ferromagnetic member and one of said second ferromagnetic members, and with said second electric conducting member disposed between said first ferromagnetic member and the other of said second ferromagnetic members;
• an electric connecting member electrically integrated with each of the electric conducting members, said electric connecting member being formed along an end portion of the electric conducting member;
• wherein, upon connection to said second electromagnetic shielding panel, at least one of said ferromagnetic members is magnetically coupled to a ferromagnetic member of said second electromagnetic shielding panel, and the electric conducting member is electrically connected to an electric conducting member of said second electromagnetic shielding panel.

An electromagnetic shielding exit/entrance structure comprising:

• an electromagnetic shielding panel including at least one ferromagnetic member formed in a shape of a panel having a cutout portion forming a first opening, said first opening defining an edge portion, said electromagnetic shielding panel further including an electric conducting member formed in a shape of a panel and disposed substantially in parallel to the ferromagnetic member, said electric conducting member having an opening with a size corresponding to said first opening of the ferromagnetic member, and an electric connecting member electrically integrated with the electric conducting member, said electric connecting member being formed along an edge portion of the electric conducting member;
• and
• an electromagnetic shielding door member including at least one ferromagnetic member formed in a shape of a panel having a size larger than that of said first opening of the ferromagnetic member of said electromagnetic shielding panel, an electric conducting member formed in a shape of a panel and disposed substantially in parallel to the ferromagnetic member, and an electric connecting member electrically integrated with the electric conducting member, said electric connecting member being formed along an edge portion of the electric conducting member,
• wherein said electromagnetic shielding door member is fitted within the first opening of said electromagnetic shielding panel to be slidable so as to open or close the first opening, and
• wherein the electric connecting member of the electromagnetic shielding panel contacts the electric connecting member of the electromagnetic shielding door member when the electromagnetic shielding door member closes the first opening of the electromagnetic shielding panel.
