Dynamic token is the hardware token using dynamic password, and it is that a kind of secure identity confirms product, and its storage inside has responsive information.Present stage, the method obtaining inner sensitive information is first disassembled by its housing, then by the bare spots read of sensitive information on internal circuit board.In order to protect inner sensitive information, the baroque Anti-dismounting structure of general employing now, but this Anti-dismounting structure cost is often high.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of dynamic token.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of dynamic token, comprise spill housing, battery is disposed with from the bottom up in the groove of described spill housing, token circuit board and display screen, described display screen is connected with spill housing by screw, described token circuit board is fixed on the back side of display screen, the bottom surface of described token circuit board is provided with the first conducting strip and the second conducting strip, the two ends that described first conducting strip and the second conducting strip are powered with token circuit board are respectively connected, the bottom portion of groove of described spill housing is provided with the 3rd conducting strip and the 4th conducting strip, described 3rd conducting strip and the 4th conducting strip are relative with the second conducting strip with the first conducting strip respectively, and be connected with the positive pole of battery and negative pole respectively, described 3rd conducting strip and the 4th conducting strip are all vertically provided with power spring, when display screen is confined on spill housing, power spring on first conducting strip contacts with the 3rd conducting strip, power spring on second conducting strip contacts with the 4th conducting strip, token power on circuitry.
Described display screen is also coated with one deck peep-proof film.
Described peep-proof film also applies one deck fluid sealant.
Described battery is button cell.
Described power spring is copper spring.
Described first conducting strip, the second conducting strip, the 3rd conducting strip and the 4th conducting strip are copper current-conducting piece.
The beneficial effect that the present invention reaches: 1, the sensitive information of dynamic token is all stored in the RAM district of token circuit chip, only under the state of continued power, sensitive information is kept at store status, once power-off sensitive information will disappear, the present invention utilizes this feature of dynamic token, token circuit board is fixed on the back side of display screen, token circuit is powered by power spring, lay down once display screen is split, the power supply of token circuit will disconnect, sensitive information also can disappear, effectively achieve the object of Anti-dismantling, solve the problem that existing Anti-dismounting structure cost is high, 2, display screen of the present invention is also coated with one deck peep-proof film, effective prevents others spying on, and ensures sensitive information safety further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of dynamic token, comprise spill housing 1, battery 2 is disposed with from the bottom up in the groove of spill housing 1, token circuit board 3 and display screen 4, display screen 4 is connected with spill housing 1 by screw 5, token circuit board 3 is fixed on the back side of display screen 4, namely display screen 4 and token circuit board 3 are fixed as an entirety, the bottom surface of token circuit board 3 is provided with the first conducting strip 6 and the second conducting strip 7, the two ends that first conducting strip 6 is powered with token circuit board 3 respectively with the second conducting strip 7 are connected, the bottom portion of groove of spill housing 1 is provided with the 3rd conducting strip 8 and the 4th conducting strip 9, 3rd conducting strip 8 and the 4th conducting strip 9 are relative with the second conducting strip 7 with the first conducting strip 6 respectively, and be connected with the positive pole of battery 2 and negative pole respectively, here battery 2 is button cell, 3rd conducting strip 8 and the 4th conducting strip 9 are all vertically provided with power spring 10, when display screen 4 is confined on spill housing 1, power spring 10 on first conducting strip 6 contacts with the 3rd conducting strip 8, power spring 10 on second conducting strip 7 contacts with the 4th conducting strip 9, token power on circuitry.
Above-mentioned power spring 10 is copper spring, and the first conducting strip 6, second conducting strip 7, the 3rd conducting strip 8 and the 4th conducting strip 9 are copper current-conducting piece.
In order to prevent others spying on, ensureing sensitive information safety further, also covering one deck peep-proof film 11 on the display screen 4, peep-proof film 11 also applies one deck fluid sealant 12.
The sensitive information of dynamic token is all stored in the RAM district of token circuit chip, only under the state of continued power, sensitive information is kept at store status, once power-off sensitive information will disappear, above-mentioned dynamic token utilizes this feature of dynamic token, token circuit board 3 is fixed on the back side of display screen 4, token circuit is powered by power spring 10, lay down once display screen 4 is split, first conducting strip 6 and the second conducting strip 7 can depart from power spring 10, the power supply of token circuit will disconnect, sensitive information also can disappear, effectively achieve the object of Anti-dismantling, solve the problem that existing Anti-dismounting structure cost is high.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
