The encrypted keyboard can meet the overall balanced requirement of connectivity and reliability of a protective device, so that the reliability of the encrypted keyboard is improved.
Description
Technical field
The utility model relates to finance device, relates in particular to the Encryption Keyboard that is provided with in the finance device.
Background technology
Encryption Keyboard because will and preserve sensitive data in order to input, so must there be anti-the stealing also of attack protection self-destruction to occur under insecure environments, promptly possesses functions such as tamper, pick-proof and replacing-proof.
Chinese patent CN1812031 discloses a kind of metal encrypted keyboard, comprise the panel that distributes successively from top to bottom, liner plate, sealing gasket, the conductive rubber keypad, button is electrically connected printed circuit board (PCB) and base, and described panel and base surround out the keyboard cavity, be provided with keyboard in this cavity and handle, also comprise the little axle of protection between described panel and liner plate with printed circuit board (PCB) and supplying cell; Described keyboard is handled can be divided into function of keeping secret processing section and unclassified function treatment part with printed circuit board (PCB), and the one side of the placement components and parts of described function of keeping secret processing section is sealed with protective cover.The inside surface of described protective cover is provided with the safeguard protection line layer, and the lead that is labyrinth pattern cabling on it is connected by web member with circuit on the printed circuit board (PCB) with the processing of keyboard function of keeping secret.Be provided with microprocessor in this printed circuit board (PCB), the little axle of this protection has constituted the protection module that links to each other with this microprocessor jointly with protective cover.
Wherein, connector in order to circuit on the safeguard protection line layer of the inside surface that connects protective cover and the printed circuit board (PCB), adopt the single device that is flexible coupling, for example: zebra bar etc., there is anti-ambient temperature differences in soft connector, is easy to generate physical change as defectives such as distortion, expansion, contractions in different temperatures; Adopt single hard connector, for example: connect shell fragment, thimble-type etc., there is the relatively poor defective of switching performance under the external force situations such as resisting vibration or impact in rigid connector.
As seen, existing syndeton can not satisfy the requirement of the general equilibrium of the connectivity of protective device and reliability well, and easily the appearance of illegal unlatching is wrong to start the self-destruction action because of loose contact takes for, and causes Encryption Keyboard work unreliable.
The utility model content
The technical problems to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and proposes a kind of Encryption Keyboard of syndeton of requirement of the general equilibrium with the connectivity that can satisfy protective device and reliability.
The utility model solves the problems of the technologies described above the technological means that is adopted and comprises; a kind of Encryption Keyboard is proposed; comprise housing and the Circuits System that is arranged in this housing; this Circuits System comprises that its printed circuit board (PCB) that is provided with microprocessor and its inside surface are provided with the protective cover of safeguard protection line layer; this protective cover is fixed on this printed circuit board (PCB); thereby this protective cover also is electrically connected with this printed circuit board (PCB) by at least one bindiny mechanism this safeguard protection line layer can be electrically connected with this microprocessor, and each bindiny mechanism comprises soft connector and rigid connector.
This soft connector and rigid connector are arranged on this printed circuit board (PCB).
This soft connector is consistent with the setting height(from bottom) of rigid connector on this printed circuit board (PCB).
It is consistent that this soft connector and rigid connector are fixed on this printed circuit board (PCB) caused decrement stroke at this protective cover.
This soft connector is a zebra bar web member.
This rigid connector is the thimble-type web member that includes at least one pin.
The number of this bindiny mechanism is two.
This protective cover is rectangular, and two diagonal angles of these two bindiny mechanisms and this protective cover are provided with accordingly.
Compared with prior art; Encryption Keyboard of the present utility model; by bindiny mechanism being arranged to comprise soft connector and rigid connector simultaneously, can satisfying the requirement of the general equilibrium of the connectivity of protective device and reliability, thereby improve the reliability of Encryption Keyboard.
Description of drawings
Fig. 1 is the structural drawing of Encryption Keyboard embodiment of the present utility model.
Embodiment
In order to further specify principle of the present utility model and structure, now in conjunction with the accompanying drawings preferred embodiment of the present utility model is elaborated.
Fig. 1 is the structural drawing of Encryption Keyboard embodiment of the present utility model.This Encryption Keyboard comprises housing and the Circuits System that is arranged in this housing; this Circuits System comprises that its printed circuit board (PCB) that is provided with microprocessor 1 and its inside surface are provided with the protective cover 2 of safeguard protection line layer 21; this protective cover 2 is fixed on this printed circuit board (PCB) 1; thereby this protective cover 2 also is electrically connected with this printed circuit board (PCB) 1 by two bindiny mechanisms 3 this safeguard protection line layer 21 can be electrically connected with this microprocessor, and each bindiny mechanism 3 comprises soft connector 31 and rigid connector 32.This protective cover 2 is roughly rectangular, and these two bindiny mechanisms 3 are provided with accordingly with two diagonal angles of this protective cover 2.
This soft connector 31 and rigid connector 32 can be arranged on this printed circuit board (PCB) 1.
This soft connector 31 is consistent with the setting height(from bottom) of rigid connector 32 on this printed circuit board (PCB) 1, and both are fixed to caused decrement stroke unanimity on this printed circuit board (PCB) 1 at this protective cover 2.
This soft connector 31 can be selected zebra bar web member for use.
This rigid connector 32 can be selected the thimble-type web member of three pins for use.
Compared with prior art, the usefulness brought of Encryption Keyboard of the present utility model comprises:
Single line on the safeguard protection line layer 21 can effectively be connected with rigid connector 32 simultaneously by soft connector 31 when connecting, be subjected to normal outside world, as get into the cave or steal etc. under the situation, thereby can effectively detect destruction, protection sensitive data; Reduce or during bad connection, another connector still can keep high performance connection not destroyed by false triggering with the secure data of guaranteeing Encryption Keyboard in the single connector performance of certain or certain.Thereby, can remedy the shortcoming separately of two kinds of connectors, have both the advantage of two kinds of connectors simultaneously, safe and reliable with what guarantee to connect.
