having an opening device with shock absorbers, a locking device, a ventilation device, a shielded viewing window, a universal interface board for the I / O controller.

A disadvantage of the known containers is the lack of shielding of electromagnetic radiation of equipment that ensures the functioning of computing devices and office equipment placed in the container.

A well-known container for testing telecommunications devices (patent KR No. 1020070029926 A dated 09/12/2005) having a shielded case and cover with an electrically conductive material, a connection of the cover to the base using pneumatic cylinders and with the possibility of rotation when opening and closing, means of shielding the rectangular connector of the base and cover in closed condition.

A disadvantage of the known containers is the lack of shielding of electromagnetic radiation of equipment that ensures the functioning of computing devices and office equipment placed in the container.

The technical problem solved by the utility model is the creation of a container that provides shielding of electromagnetic radiation from equipment that ensures the functioning of computing devices and office equipment placed in it.

The technical problem is solved in a container that shields electromagnetic radiation, consisting of a housing of electrically conductive material having a bottom, side, front and rear walls and a cover connected by loops and cylindrical shock absorbers with the possibility of rotation for opening and closing; means of shielding in the closed state, placed around the perimeter of the connector cover and housing; ventilation panels; a locking device providing power contact connection of the shielding means when closing the lid; universal interface board of the input / output controller installed in the housing; at the same time, on the walls inside the case there are: a power supply unit, a power splitter, a shielded line filter, a network hub, a media converter and shielded input-output connectors for fiber-optic communication lines of a media converter (“twisted-fiber-optic cable”).

To visually monitor the operation of the device, a viewing window with an optically transparent filter that shields electromagnetic radiation can be installed in the housing cover.

To prevent unauthorized use of the device, the housing and the lid may have a locking device that allows sealing the container in the closed state.

To optimize the thermal regime of computing devices, office equipment and equipment that are located inside the container, at least one ventilation unit is installed on one of the housing walls, consisting of a ventilation panel shielding electromagnetic radiation and a fan, and a ventilation unit is installed on the opposite wall panel.

The technical problem - the creation of a container that provides shielding of electromagnetic radiation from equipment that ensures the functioning of computing devices and office equipment placed in it - was solved by the following combination of distinctive features: a power supply unit, a power splitter, a shielded line filter, a network hub, a media converter are installed on the walls inside the case and shielded input-output connectors of fiber-optic communication lines of a media converter (“twisted pair-FOCL”).

This set of distinctive features was not found in the process of patent information search, therefore, the utility model meets the criterion of "novelty."

The container with shielding electromagnetic radiation (Figs. 1-9) consists of a housing 1 made of an electrically conductive material having a bottom 2, side walls 3 and 4, a front wall 5, a rear wall 6 and a cover 7 connected by loops 8 and cylindrical shock absorbers 9 with the possibility of rotation for opening and closing; means 10 (Fig.6) shielding in the closed state, placed around the perimeter, respectively, of the connector cover 7 (means 10A, Fig.4) and the housing 1 (means 10b, Fig.2); a locking device 11 (FIG. 2), providing a power contact connection of the shielding means 10 when closing the lid 7; universal interface board 12 (figure 2) of the input / output controller installed in the housing 1; while on the walls 3, 4, 6 of the housing 1 (FIG. 2), a power supply 13, a power splitter 14, a shielded line filter 15, a network hub 16 and a media converter 17 are installed; and in one of the walls there are shielded connectors 18 (Fig. 7) of the input-output of fiber-optic communication lines of the media converter 17 (“twisted pair FOCL”).

For visual monitoring of the operation of the protected device (not shown) in the cover 7 of the housing 1 can be installed a viewing window 19 (figure 3) with an optically transparent filter (not shown) that shields electromagnetic radiation.

To exclude unauthorized use of the protected devices, the housing 1 and the cover 7 may have a locking device 11a (Fig.3, 8), allowing the container to be sealed in a closed state.

To optimize the thermal regime of the protected computing devices and office equipment, at least one ventilation unit 20 (FIGS. 5, 9), consisting of an electromagnetic radiation shielding ventilation panel 21 (FIG. 7) and a fan 22, can be installed on the wall 4 of the housing 1 and on the opposite wall 3 there is a ventilation panel 21a (Fig. 9). With a small flow of heat generated by the protected computing devices or office equipment, ventilation panels 21 and 21a without fan 22 are placed on walls 3 and 4. The number of ventilation panels can be increased.
