Abstract
The utility model relates to a lighting window for an electronic shielding shelter. The lighting window comprises a metal window frame, wherein outer plate glass and inner shielding glass which are mutually parallel are embedded in the metal window frame; the shielding glass comprises outer tempered plate glass, middle tempered plate glass and inner tempered plate glass which are parallel compounded, an outer shield screen mesh is clamped between the outer tempered plate glass and the middle tempered plate glass, and an inner shielding screen mesh is clamped between the middle tempered plate glass and the inner tempered plate glass; and the shielding screen meshes are square hole metal screen meshes which are woven by mutually vertical warp and weft metal wires and have electrical conductivity. According to the lighting window, the mutually staggered shielding screen meshes are clamped between the three pieces of tempered plate glass of the shielding glass, so that the shielding capacity of the shielding glass to electromagnetic waves is better, and the shielding glass can be used as a lighting window and arranged on an electronic shielding shelter which has a larger shielding range to the electromagnetic waves and has a shielding capacity larger than 40dB. Due to the lighting window, the technical problem that a shelter with an electromagnetic shielding capacity larger than 40dB cannot be provided with a lighting window within a frequency range of 100KHz to 10GHz is solved.

The electronic shield shelter is used for electronic equipment and microelectronic device are installed in the cabin, in order to guarantee electronic equipment and the microelectronic device reliable operation in the cabin, does not receive electromagnetic interference, and the cabin body of electronics shelter will have certain shielding properties to the electromagnetic wave of surrounding environment.
Light inlet window has window frame of metal, is embedded with transparent sheet glass in the window frame of metal, and window frame is embedded in the daylighting fenestra on cabin, the side plate of cabin body; The effect with printing opacity of only keeping out the wind of common sheet glass; Electromagnetic wave is not had shielding action, and for the borrow light that makes the electronic shield shelter has shielding action to electromagnetic wave, the sheet glass that in electronic shield shelter light inlet window, is embedded with is shield glass; Shield glass has two blocks of tempering sheet glass that are combined with each other; Between two blocks of tempering sheet glass, accompany wire lath, wire lath has electric contact, during installation; Window frame of metal electrically contacts with the exterior skin of cabin, electronic shield shelter side plate and links to each other, and the electric contact of wire lath electrically contacts with the inside panel of cabin, electronic shield shelter side plate and links to each other.
In the prior art, shield glass has only two blocks of tempering sheet glass in electronic shield shelter light inlet window, has only the layer of metal net between two blocks of tempering sheet glass.
The light inlet window of this electronic shield shelter is not fine to the electromagnetic wave shielding ability; Electronic shield shelter with this light inlet window is that shielding electromagnetic waves ability in 100K～10GHz scope is not more than 40dB to frequency; If when the electronic shield shelter required the electromagnetic wave shielding ability by force, then above-mentioned light inlet window can not be installed on the stronger electronic shield shelter of electromagnetic wave shielding ability.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency, proposes a kind of byer force to the electromagnetic wave shielding ability, can be installed in the electronic shield shelter light inlet window on the electronic shield shelter big to the electromagnetic wave shielding scope, that screening ability is stronger.
The utility model is realized with following method.
Electronic shield shelter light inlet window has window frame of metal; Be embedded with outer sheet glass parallel to each other and internal layer shield glass in the window frame of metal; That shield glass has is outer, in, interior three blocks of parallel tempering sheet glass that are combined with each other; Outside one and in accompany outer shielding silk screen between tempering sheet glass, in accompany internal layer shielding silk screen between a tempering sheet glass and the interior tempering sheet glass, the shielding silk screen is the square-mesh wire cloth that forms with orthogonal longitude and latitude metal wire knitted; The shielding silk screen has electric contact, and outer shielding silk screen and internal layer shielding silk screen are staggered compound.
The shield glass of the utility model has three blocks of tempering sheet glass; Accompany the shielding silk screen respectively between the tempering of the piece in twos sheet glass of three blocks of tempering sheet glass; Shield glass with two-layer shielding silk screen is better to the electromagnetic wave shielding ability, can be used as light inlet window and is installed on, the electronic shield shelter of screening ability greater than 40dB big to the electromagnetic wave shielding scope.Solved and in 100KHz～10GHz scope inner shield ability the technical barrier of light inlet window can not be installed greater than the shelter of 40dB at present.
Below in conjunction with accompanying drawing, the utility model is done explanation further.
