Description
Technical field
The utility model relates to one kind can satisfy the safety device that PCI authenticates (International Safety Certification) keyboard distinguishing value,
The device is mainly used in financial payment terminal.
Background technique
Since the safety requirements rank that the PCI certification of financial payment terminal inputs client password is relatively high, so key
Project checking of the physical protection of disk area in PCI verification process is also especially stringent.Previous keyboard region physical protection form list
One, productibility is poor.Constantly upgrade recently as PCI certification version, the single protected mode in keyboard region is no longer satisfied
PCI keyboard authenticates score value, causes the score value of entire safety certification that cannot meet the requirements.
Summary of the invention
The purpose of this utility model is: meeting PCI for the protection requirement of keyboard area and reaches judge score value.
In order to achieve the above object, there is provided one kind can achieve PCI certification keyboard for the technical solution of the utility model
The safety device of distinguishing value, including the flexible film PCB between rubber keyboard and PCB main board, PCB main board is equipped with N number of
Static security contact and M dynamic security contact, N >=1, M=2K, K >=1, M dynamic security contact are divided into K pairs, each static state
Safety contact includes outer ring safety component and the inner ring safety component in the safety component of outer ring, which is characterized in that soft thin
Film PCB is equipped with M contact and N number of metal metal dome, and M contact and M dynamic security contact are divided into K to touching correspondingly
Point pair, each pair of contact is connected to the cabling snakelike all the way by being wound on flexible film PCB, and the flexible film is fitted in
After on PCB main board, each contact is in contact by respective conductive carbon granules with corresponding dynamic security contact；N number of metal pan is young
Piece and N number of static security contact correspond, after the flexible film is fitted on PCB main board and installs the rubber keyboard,
The outer ring safety component of each static security contact and short circuit is formed by corresponding metal metal dome positioned at outer ring safety component.
Preferably, the diameter of the contact is 2mm.
Preferably, the quantity of the contact is 4, and 4 contacts are distributed on 4 angles of the flexible film PCB.
Preferably, the line width 6mil of the snakelike cabling, line-spacing 6mil.
Preferably, the flexible film PCB has at least 2 layers.
Due to the adoption of the above technical scheme, device provided by the utility model has the following beneficial effects:
1, have 3 heavy protected modes: dynamic protection, static protection, snakelike cabling fully meet PCI for keyboard area
Requirement, and reach score value；
2, after using this device, snakelike cabling does not have in the keyboard area of mainboard around the reduction main PCB number of plies reduces
The cost of complete machine.
Detailed description of the invention
Fig. 1 is the schematic diagram of the flexible film PCB in embodiment (gum faces outwardly)；
Fig. 2 is the schematic diagram of static security contact.
Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
A kind of safety device can achieve PCI certification keyboard region score value provided by the utility model is mounted on rubber keyboard
Between PCB main board.Wherein, have 5 static security contacts and 4 dynamic security contacts on PCB main board.Wherein, 4 dynamics
Safety contact is divided into two pairs, and when certain touches to short circuit dynamic security, equipment is without exception, and equipment is abnormal when breaking.Static security
The structure of contact is as shown in Fig. 2, include the outer ring safety component B and inner ring safety component A in the safety component B of outer ring.When
When inner ring safety component A is with the B short circuit of outer ring safety component, equipment is without exception, and equipment is abnormal when breaking.
As shown in Figure 1, safety device disclosed in the present embodiment includes flexible film PCB1, there are 4 on flexible film PCB1
Contact 2 and 5 metal metal domes 3.Contact 2 and dynamic security contact correspond, and are correspondingly divided into 2 pairs of contacts pair.Often
A pair of contact is connected to the cabling snakelike all the way by being wound on flexible film PCB1, then shares the snakelike cabling of two-way.Every road
Snakelike routing line width is 6mil, line-spacing 6mil, is unordered wiring.After flexible film PCB1 is fitted on PCB main board, each
Contact 2 is in contact by corresponding conductive carbon granules with corresponding dynamic security contact.
5 metal metal domes 3 are then corresponded with 5 static security contacts, and flexible film PCB1 is fitted on PCB main board
And after the installation rubber keyboard, after loading onto equipment shell urgent screw, shell is simultaneously pressed down 5 metal metal domes 3
Firmly, the inner ring safety component A and outer ring safety component B of each static security contact is made to pass through corresponding 3 short circuit of metal metal dome.
The protected mode one of the utility model is realized by contact 2 and snakelike cabling: due to snakelike routing line width and line-spacing
It is all very narrow and be covered with entire flexible film PCB1, while without rule when being routed, if so attacker is directly to soft
Property film PCB1 destroyed if will lead at least any pair open circuit of 2 pairs of contact centerings, to further result in PCB master
To open circuit occurs, master chip can recognize machine at once has exception at least any pair of dynamic security contact on plate.
The protected mode two of the utility model is realized by metal pan son piece 3: if attacker slightly loosens equipment shell,
Metal metal dome 3 can rebound, and open circuit, master chip occur for the inner ring safety component A and outer ring safety component B of static security contact
Machine can be recognized at once has exception
The protected mode two of the utility model is realized by contact 2 and conductive carbon granules: if professional attacker does not loosen equipment
Shell, but use the attack form destroyed to shell, it will cause the loosening of any a line of flexible film PCB1,
So as to cause falling off for conductive carbon granules, so that dynamic security contact is not contacted with contact 2, dynamic security contact open, master chip
Also machine can be recognized at once has exception.
