Abstract
The utility model discloses a high-voltage shielding device of a liquid crystal display. The high-voltage shielding device comprises a high-voltage board shielding case and a display screen support. The high-voltage board shielding case is a metal case with a plurality of radiating holes, side boards are arranged around the metal case, the back board of the high-voltage board shielding case is slightly larger than a display screen high-voltage driver board, fixing screw holes are formed on the back board, screw holes are formed at the upper ends and the left ends of the side boards of the high-voltage board shielding case, and cable ports are formed on the side boards of the high-voltage board shielding case; the display screen support is a board body on which a display screen groove is formed on the front side, a protrusion is formed on the back, and a plurality of fixing screw holes are formed on the folded edges on the periphery; and the high-voltage board shielding case is positioning at the left upper corner of the back of the display screen support, and both the upper ends and the left ends of the side boards of the high-voltage board shielding case are positioned outside the display screen support. As the shielding case with smaller area is adopted, both the wire-insertion and the assembly become comparatively simple, the production efficiency is improved, and both the raw material and the cost are saved.
Description
Technical field
The utility model relates to a kind of screening arrangement, more specifically to the LCDs high-tension shielding device that uses on vector network analyzer.
Background technology
The brightness regulation of LCDs is closely bound up with the performance that shows the high drive plate, show that the high drive plate also is a critical piece of lighting display screen work simultaneously, yet show that the high drive plate sends high-intensity electromagnetic radiation when work, can work the mischief to liquid crystal display screen and user, so for to existing electromagnetic wave source to shield, prevent electromagnetic interference, generally all will be showing that the high drive plate is arranged in the radome, radome can play the effect of shielding, and the electromagnetic wave of the overwhelming majority is blocked in cover.General radome area is bigger, not only is difficult for installing, and has used more raw material, and cost is higher.Because the heat that produces when showing the work of high drive plate is also than higher, general radome mainly plays shielding action, be difficult to reduce effectively the temperature that is produced, display screen is in the hot operation state, has reduced the useful life of product so to a certain extent.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of and is convenient to install, saves raw material, cost is lower and the reasonable LCDs high-tension shielding of radiating effect device.
The purpose of this utility model is achieved in that a kind of LCDs high-tension shielding device comprises hardboard radome and display/panel bracket, the hardboard radome is a metal cap that offers a plurality of louvres, side plate is arranged around the metal cap, the area of its backboard of hardboard radome is slightly larger than the area of display screen high drive plate, and also be provided with fixing threaded hole (screw on the backboard is corresponding with screw on the display screen high drive plate) on the backboard, its side plate of hardboard radome upper end and left end all offer fixing threaded hole (screw of offering on this screw and the vector network analyzer panel is corresponding), offer cable port on the hardboard radome side plate; Display/panel bracket is that a front offers display screen groove, back for the plate face that protrudes, the flanging place offers the plate body of a plurality of fixing threaded holes all around, the hardboard radome is positioned at the upper left corner at display/panel bracket back, and hardboard radome side plate upper end and left end all are positioned at the display/panel bracket outside.In use, display screen high drive plate is installed in the hardboard radome, screw is corresponding to screw on the display screen high drive plate screw on the hardboard radome backboard, and screw is then followed the screw correspondence of offering on the vector network analyzer panel and passed through screw on hardboard radome side plate upper end and the left end.
The utility model is because of having adopted the less radome of area, and plug wire and assembling are all fairly simple, have not only improved production efficiency, and have saved raw material, provide cost savings.Can better dispel the heat by louvre on the radome to display screen high drive plate, avoid simultaneously the interference of other parts on every side, guaranteed also that to a certain extent the high pressure master control borad avoids dust, thereby improved to a certain extent the useful life of LCDs.
Description of drawings
Fig. 1 is a hardboard shielding case structure schematic diagram;
Fig. 2 is the display/panel bracket structural representation;
Fig. 3 is the schematic diagram after the utility model assembling.
Among the figure: 1, hardboard radome; 2, louvre; 3, backboard fixing threaded hole; 4, side plate upper end screw; 5, side plate left end screw; 6, display/panel bracket.
Embodiment
The utility model is described in further detail to reach embodiment below with reference to the accompanying drawings.
As shown in Figure 3: a kind of LCDs high-tension shielding device is made up of hardboard radome 1 and display/panel bracket 6.Concrete installation process is: at first as shown in Figure 1, make a rectangle hardboard radome 1, offer a plurality of louvres 2 above the hardboard radome, the area of its backboard is slightly larger than the area of display screen high drive plate, and also be provided with on the backboard two with display screen high drive plate on the corresponding fixing threaded hole 3 of screw; Its side plate upper end, left end offers with the vector network analyzer panel on the corresponding screw 4 and 5 of screw offered; Rectangle display/panel bracket 6 of making shown in Figure 2 for another example, display/panel bracket 6 are that a front offers display screen groove, back for the plate face that protrudes, the flanging place offers the plate body of a plurality of fixing threaded holes all around; Assemble at last, hardboard radome 1 is positioned at the upper left corner at display/panel bracket 6 backs, screw 3 is corresponding to screw on the high pressure master control borad screw on the backboard, and 5 of side plate upper end screw 4 and side plate left end screws are followed the screw correspondence of offering on the vector network analyzer panel and passed through screw.
Claims (2)
