Technical field
The utility model relates to and moves the POS terminal, concrete ground say so a kind of LCD screen data protecting device and mobile POS terminal thereof.
Background technology
LCDs is the human-computer interaction interface that moves the POS terminal device.Have a lot of offenders to think that a blanking method is stolen the user's that swipes the card password and other useful informations to the greatest extent at present, LCDs is exactly the key object of being attacked.The offender utilizes information such as display device miscue user card punching and input password, thereby obtains user's information.Existing mobile POS terminal device generally includes shell, LCD display and PCB mainboard; LCD display is installed on the fore shell of shell; The setting of PCB mainboard in the enclosure; LCD display is connected with the PCB mainboard through connecting line, and this structure makes criminal dismantle the attack LCD display easily, carries out stealing of data such as password.Because development in science and technology now is rapid, it is more and more superb to steal means, and this just requires the sensitivity of anti-disassembling function necessary increasingly high, and existing protective device can not satisfy the requirement of sensitivity, and it is bigger to take up room, and can make the entire mechanism thickening.
Summary of the invention
The purpose of the utility model is under attack easily for the LCD display that solves the prior art existence, in data transmission procedure, has the technical matterss such as hidden danger that are stolen, and a kind of LCD screen data protecting device and the mobile POS terminal thereof that provide.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to be achieved:
A kind of LCD screen data protecting device; It comprises LCD display and PCB mainboard; It is characterized in that: display/panel bracket and two electric silica gel carbon granules are set between said LCD display and the PCB mainboard; Have two through holes on the said display/panel bracket, two and the corresponding trigger point of said lead to the hole site are set on the said PCB mainboard, said electric silica gel carbon granules is inserted in the said through hole and aims at the trigger point of said PCB mainboard.
In the further detailed structure of the utility model, also have following technical characterictic: said two electric silica gel carbon granules are arranged on the diagonal angle of said display/panel bracket.
In the further detailed structure of the utility model, also have following technical characterictic: said display/panel bracket is a groove type, and said LCD screen is arranged in the said display/panel bracket.
The utility model is based on above-mentioned LCD screen data protecting device; A kind of mobile POS terminal that this LCD screen data protecting device is housed also is provided; It comprises setting LCD screen data security protecting device in the enclosure; Said LCD screen data security protecting device comprises LCD display and PCB mainboard, it is characterized in that: display/panel bracket and two electric silica gel carbon granules are set between said LCD display and the PCB mainboard, have two through holes on the said display/panel bracket; Two and the corresponding trigger point of said lead to the hole site are set on the said PCB mainboard, and said electric silica gel carbon granules is inserted in the said through hole and aims at the trigger point of said PCB mainboard.
In the further detailed structure of the utility model, also have following technical characterictic: said two electric silica gel carbon granules are arranged on the diagonal angle of said display/panel bracket.
In the further detailed structure of the utility model, also have following technical characterictic: said display/panel bracket is a groove type, and said LCD screen is arranged in the said display/panel bracket.
Compared with prior art; The advantage and the good effect of the utility model are: because the utility model has adopted electric silica gel carbon granules contact antiwithdrawal device, through the structural design of electric silica gel carbon granules, realized frivolous framework; And guaranteed the effective elasticity of silica gel carbon granules, realized its sensitive contact.As long as move the distance of LCD display 0.3mm, the electric silica gel carbon granules will flick, thereby the mainboard trigger point is broken off, and signal power source disappears, will the trigger protection system, and complete machine was lost efficacy, thereby make private data be able to protection.
