Abstract
The utility model discloses a shielding device for a displayer which comprises a metal panel of a cabinet internally installed with a displayer. The mental panel of the cabinet is provided with a groove matching with the displayer. A first conductive rubber pad, wire mesh conductive glass and a second conductive rubber pad are provided successively in the groove; one side of the first conductive rubber pad is in contact with the conductive surface of the groove, and the other side of the first conductive rubber pad is in contact with the wire mesh conductive glass; one side of the second conductive rubber pad is in contact with the wire mesh conductive glass; and the other side of the second conductive rubber pad is in contact with the displayer. The shielding device has advantages of high performance of shielding the displayer, high pertinency, simple structure, easy assembling, shock and vibration resistance, stability, and free daily maintenance. Furthermore, the wire mesh conductive glass has good light-admitting quality, which does not affect the displaying effect.
Description
Technical field
The utility model relates to a kind of display screen windows screening arrangement.
Background technology
Because the restriction of operational environment, partly equipment, subsystem, system's intensive work form common electromagnetic environment.For guaranteeing each class of electronic devices and subsystem operate as normal and possess good electromagnetism environment in common electromagnetic environment, standard GJB151A-1997 has stipulated relevant control requirement.For satisfying RE102 among the GJB151A-1997, RS103 requirement, equipment enclosure, cabinet should possess good shielding properties.If perforate is installed display screen and is not carried out professional shielding processing on metal closed rack, cabinet, equipment enclosure, cabinet will produce electromagnetic leakage, destroy electromagnetic environment, peripheral equipment is formed interference, equipment self antijamming capability decline cisco unity malfunction can't be by correlation test among the GJB151A-1997.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of display screen windows screening arrangement is provided, can effectively shield high band magnetic field, electric field radiation emission, can stop effectively that high band magnetic field, electric field radiation disturb, and help equipment to pass through the GJB151A-1997 correlation test.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of display screen windows screening arrangement, the metal cabinet panel that comprises built-in display screen, described metal cabinet panel has the groove that adapts with display screen, and set gradually first conductive rubber pad, woven wire electro-conductive glass and second conductive rubber pad in this groove, the one side of first conductive rubber pad contacts with the conductive plane of groove, its another side contacts with the woven wire electro-conductive glass, the one side of second conductive rubber pad contacts with the woven wire electro-conductive glass, and its another side contacts with display screen.
And the two sides of described first conductive rubber pad is affixed on the conductive plane and woven wire electro-conductive glass of groove respectively by two-sided conductive tape; The one side of described second conductive rubber pad is affixed on the woven wire electro-conductive glass by two-sided conductive tape, and its another side contacts with display screen frame.
And described display screen is anchored on the metal cabinet panel by screw.
Advantage of the present utility model is: 1, use this new-type display screen window screening arrangement screening effectiveness height, with strong points; 2, simple in structure, easy to install; 3, possess certain shock resistance, vibration ability; 4, good stable is arranged, need not regular maintenance; 5, woven wire electro-conductive glass light transmission is good, does not influence display screen display effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional arrangement drawing of the present utility model.
Wherein, 1, the metal cabinet panel, 2, first conductive rubber pad, 3, the woven wire electro-conductive glass, 4, second conductive rubber pad, 5, display screen.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Present embodiment provides a kind of display screen windows screening arrangement, as depicted in figs. 1 and 2, the metal cabinet panel 1 that comprises built-in display screen 5, described metal cabinet panel 1 has the groove that adapts with display screen 5, and set gradually first conductive rubber pad 2, woven wire electro-conductive glass 3 and second conductive rubber pad 4 in this groove, the one side of first conductive rubber pad 2 contacts with the conductive plane of groove, its another side contacts with woven wire electro-conductive glass 3, the one side of second conductive rubber pad 4 contacts with woven wire electro-conductive glass 3, and its another side contacts with display screen 5.
Further, the two sides of above-mentioned first conductive rubber pad 2 is affixed on the conductive plane and woven wire electro-conductive glass 3 of groove respectively by two-sided conductive tape; The one side of described second conductive rubber pad 4 is affixed on the woven wire electro-conductive glass 3 by two-sided conductive tape, and its another side contacts with display screen 5 frames.
Further, above-mentioned display screen 5 is anchored on the metal cabinet panel 1 by screw.
The utility model makes the frame of woven wire electro-conductive glass 3 form the seamless full fully conducting state that contacts with 1 of metal cabinet panel, be sandwiched in the full conducting of woven wire metal edge frame peripheral with it in the electro-conductive glass, display screen windows on the metal cabinet panel 1 is shielded fully, reaches by woven wire density in the selection electro-conductive glass and satisfies different electromagnetic environment requirements.After being installed, display screen 5 make conductive rubber pad produce compression, again by two-sided conductive tape effect, whole display window becomes complete, a continuous electric conductor, and screening effectiveness can reach 60dB～90dB under the perfect condition, can be by RE102, RS103 test among the GJB151A-1997.
