Abstract
An electromagnetic shielding comprising a cabinet bottom, a roof cover, side walls, stand frame, spring lamination, upper wave guide window, lower wave guide window, door knife, electric wave filter, screening glass, perspective screening glass door, back door, wave guide tube and fiber optic holder, wherein the holder are four columns mounted on the medial wall of the cabinet, the optical machine are mounted on the four mounting racks, the upper wave guide window and the lower wave guide window are arranged on the top cover and the cabinet bottom, the doors are arranged on the frame having spring laminations on the four sides, the door knives are arranged on the four sides of the door frame, the perspective screening glass door is arranged on the front side of the electromagnetic shielding rack. The invention can be used to diminish the possible injury by the electromagnetic wave to the human body.
Description
Technical field:
The present invention relates to a kind of rack that can play shielding action to electromagnetic radiation, especially a kind of computer server of placing, information equipments such as small switch, can stop electromagnetic wave to personal injury, suppress the computer electromagnetic information leakage effectively and prevent outside forceful electric power magnetic harassing and wrecking, influence the electromagnetic shielding rack of computer operate as normal
Background technology:
The use of computer now is the various aspects of people's lives such as office, school, family deeply, and electromagenetic wave radiation has caused people's attention to the injury of human body.Though the computer protecting screen is arranged on the market, also just the display front is shielded, the village magnetic wave of its side and back surface radiation can't shield.This is unfavorable for healthy.Relate to special sectors such as military affairs, national defence in addition, need the electromagnetic information of computer not leaked, it is far from being enough that protection screen only is set.
Summary of the invention:
The purpose of this invention is to provide a kind of computer, computer server, small switch placed, and can stop electromagnetic wave to personal injury, effectively suppress the computer electromagnetic information leakage and prevent the harassing and wrecking of outside forceful electric power magnetic influence the computer operate as normal the electromagnetic shielding rack.
A kind of electromagnetic shielding rack that the present invention relates to, at the bottom of it includes cabinet, top cover, sidewall, it also includes frame,, spring leaf, go up waveguide window, waveguide window, door cutter, filter, shield glass, perspective shielding glass door, back door, waveguide, optical transceiver frame are formed down;
Described frame is four and is fixed on the rack madial wall, and the optical transceiver frame is installed on four frames,
On described upward waveguide window, following waveguide window are separately positioned at the bottom of top cover, the cabinet,
Be equipped with door on the described rack, be provided with spring leaf, be provided with a cutter on doorframe four limits on door four limits
Described electromagnetic shielding cabinet front is provided with perspective shielding glass door,
Circumscripted power line, telephone signal line, incoming line in a kind of electromagnetic shielding rack of the present invention, pass separately waveguide be located at the electromagnetic shielding rack in filter and supply socket, traffic filter be connected respectively.
The front of its cabinet is provided with perspective shielding glass door in a kind of electromagnetic shielding rack of the present invention.
Bullet spring leaf in a kind of electromagnetic shielding rack of the present invention is circular arc, comb shape or undulating springs sheet, is provided with the door cutter that cooperates with described spring leaf on described doorframe.
The aperture of waveguide is 1: 10 with the length ratio in a kind of electromagnetic shielding rack of the present invention, and wall thickness is 2-4mm.
Waveguide window is to have metallic plate some, circular honeycomb hole in a kind of electromagnetic shielding rack of the present invention, and its aperture is 3-3.5mm, and its thickness of slab is 4-10mm.
A kind of electromagnetic shielding rack of the present invention is design principle and the technology with electromagnetic shielding, be applied on the electromagnetic shielding, adopt integral structure, design and manufacture the 26S Proteasome Structure and Function that both has the minisize shielding chamber, the advantage of this village magnetic screen rack and good effect are that the openable door of rack body is provided with spring leaf, connecting line between power line and each parts is provided with waveguide and filter, therefore, the rack body can effectively shield the extraneous electromagnetic radiation that produces, avoid electromagnetic wave to personal injury, also can suppress self-contained computer server, the leakage of information of equipment such as small switch.
