Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that technical scheme of the present invention is carried out clear, intactly description below, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Referring to Fig. 1-Fig. 3; The bank card payment terminal equipment that present embodiment has liquid crystal data anti-tampering protection device comprises liquid crystal display 4 and the processor P CB plate 2 below it; Liquid crystal display 4 is connected with processor P CB plate 2 through signal wire 10; Be fixed with first fender 6 and second fender 7 on the said processor P CB plate 2; Said first fender 6 and second fender 7 are the pcb board that inside is provided with the protection cabling, and said first fender 6, second fender 7 and processor P CB plate 2 surround a closed bearer bar, and said bearer bar can surround described signal wire 10 fully.
Particularly; The bank card payment terminal equipment that present embodiment has liquid crystal data anti-tampering protection device comprises housing; Housing comprises the fore shell 1 and back cover (not shown) that is fastened, and liquid crystal lens 3 and liquid crystal display 4 are housed on the fore shell 1, is provided with processor P CB plate 2 parts such as grade in the housing; After installing, said liquid crystal display 3 is positioned at processor P CB plate 2 tops; And be connected with processor P CB plate 2 through signal wire 10, being welded with first fender 6 and second fender 7 on the said processor P CB plate 2, said first fender 6 and second fender 7 are inside and are provided with the pcb board of protecting cabling; Said second fender 7 is perpendicular to the processor P CB plate 2 and first fender 6; And its height will be higher than first fender 6, and said first fender 6, second fender 7 and processor P CB plate 2 surround a closed bearer bar jointly, and said bearer bar can surround described signal wire 10 fully.
Present embodiment has the bank card payment terminal equipment of liquid crystal data anti-tampering protection device; After liquid crystal display 4 is installed; It is connected in the bearer bar that signal wire 10 just in time is crushed on liquid crystal display 4 belows, processor P CB plate 2 tops with processor P CB plate 2; And surrounded institute by first fender 6 and second fender 7 all around, can be enclosed in the said bearer bar by the second highly higher fender 7 near liquid crystal display 4 one ends, downward signal wire 10 parts that bend.All can make the protection in the plate walk thread breakage or protection cabling and ground wire are linked together no matter the stealer holes on any position of bearer bar, thereby make the data destroying of primary processor, reach the purpose of protection sensitivity.
Based on technique scheme; Optional; In order to prevent that further the assailant from distorting the data message of liquid crystal display from liquid crystal display 4 tops, also be provided with elastic conduction silicagel column 5 between said processor P CB plate 2 and the liquid crystal display 4, have through hole 9 on said first fender 6; Said electric silica gel post 5 is inserted in the said through hole 9, and is electrically connected with processor P CB plate 2.Concrete, said electric silica gel post 5 can be provided with two, and the upper left side and the lower right of corresponding said first fender 6 also should have two through holes 9, and two electric silica gel posts can be electrically connected with processor P CB plate 2.Through the extruding of shell and liquid crystal display 4, electric silica gel post 5 is contacted closely on processor P CB plate 2.Attack when the stealer will dismantle liquid crystal display 4, when stealing data, after liquid crystal display 4 was opened, electric silica gel post 5 will be upspring; Thereby do not contact with processor P CB plate 2, the protection cabling in the processor P CB plate is broken off, CPU will detect signal to attack; Thereby wipe user's in the machine sensitive data; The correctness that has effectively guaranteed liquid crystal display data with can not distorting property, better protection liquid-crystal display information has prevented distorting of liquid crystal display data.
Further; Easy for installation in order to make, simple in structure; Be easy to manufacture, said first fender 6 is a frame-type, and its lower end forms opening 11; Said second fender 7 and processor P CB plate 2, the 6 vertical settings of first fender, the 7 fixing also shutoff of said second fender are at opening 11 places of first fender 6.Concrete; Said first fender 6 is for having certain thickness frame-type thin plate; Its thickness is larger than the thickness of liquid crystal display signal wire 10, is cavity 12 between wherein, so that the signal wire 10 that liquid crystal display 4 is connected with processor P CB plate 2 can be contained in its cavity 12.The first fender lower end is an open type, so that said second fender 7 is weldingly fixed on the processor P CB plate 2, second fender 7 will block the opening 11 of first fender 6, so that data are stolen in tighter preventing.
Further, in order to make said second fender, 7 convenient welding, and can not double swerve, having slot 8 on the plate body of the openend both sides of said first fender 6, the two ends, bottom of said second fender 7 are inserted in the said slot 8.Concrete, have two ends, slot 8, the second fenders, 7 bottom on the plate body of the openend left and right sides of said first fender 6 and be inserted into respectively in the slot 8, like this, just can not double swerve behind second fender, 7 plug-in mountings.In order to make fixation, reliable, second fender, 7 bottoms are fixing with 2 welding of processor P CB plate, and the two ends, bottom are fixing with 6 welding of first fender.
Further, in order to reach tighter protection effect, said processor P CB plate 2, first fender 6, and second fender 7 be two-sided pcb board, two groups of protection cablings are set in the plate at least.Concrete, first internal protection cabling of plank adopts ground wire and the snakelike mode that detours of article one protective wire, and the spacing of ground wire and protective wire is 0.2mm; The plank another side adopts the snakelike mode that detours of second protective wire, and the spacing between the protective wire is 0.2mm.The cabling on two sides presents plumbness, no matter how the stealer holes all can make the protective wire fracture or protective wire and ground wire are linked together, thereby make the data destroying of primary processor with sensitivity, reaches the purpose of protection.
What should explain at last is: above embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although with reference to previous embodiment the present invention has been carried out detailed explanation, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that previous embodiment is put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of relevant art scheme break away from the spirit and the scope of embodiment of the invention technical scheme.
