Abstract
A protective structure for a metal keyboard of a cash recycling machine comprises an internal key circuit board of the keyboard, wherein a plurality of keyboard key contacts and six screw fixing positions are arranged on the internal key circuit board; at least two shell-opening protective key contacts are arranged between the keyboard key contacts on the internal key circuit board of the keyboard, and are connected with the circuit board after being connected in series; and the connection or disconnection of the series circuit is realized by the shell-opening protective key contacts. The design of the structure can avoid the disclosure of such confidential information as secret keys of the metal keyboard, the secret key algorithm and the like, thereby guaranteeing the safety of self-help withdrawal and deposit devices applied in the financial system.
Description
Technical field
The utility model relates to the all-in-one of depositing and withdrawing of financial sector, mainly is meant a kind of all-in-one metal keyboard protection structure of depositing and withdrawing.
Background technology
A operating surface has 16 buttons, with 4 * 4 form assembled arrangement, digital 0-9 is wherein arranged, decimal point ". ", two zero " 00 ", " cancellation ", " corrigendum ", " affirmation " and a reservation button are formed, keytop and by tangible concavo-convex mark, be installed on the cash-access money circulator, can make and carry out cash and non-cash automated transaction between client and the financial sector, comprise deposit, withdraw the money, inquire about, transfer accounts, revise multiple cash and noncash financial transactions such as password, smart card.
The metal encrypted keyboard of traditional design, because there is certain hidden danger in encrypting keyboard fail safe aspect, by some high-tech means, the keyboard key can be stolen and cracked key algorithm, this brings hidden danger just for financial sector self-service dealing fail safe aspect.
Summary of the invention
The purpose of this utility model is to provide a kind of all-in-one metal keyboard protection structure of depositing and withdrawing; 6 fixed screws by metal keyboard behind shell; make the shell protection key contacts of opening on the inner button circuit board be in normally on; just be in the guard mode of key and algorithm, overcome the deficiency that prior art exists preferably.
The realization the technical solution of the utility model is: this all-in-one metal keyboard protection structure of depositing and withdrawing comprises the keyboard button circuit board; which is provided with some keyboards contact and six screw fixed positions; wherein between the keyboard contact on the described keyboard button circuit board, be provided with the more than one shell protection key contacts of opening; this is opened shell protection key contacts and is serially connected with the series connection form and is connected with described circuit board, and the conducting or the off-state of realization series circuit.
This technical scheme also comprises:
Described to open shell protection key contacts be three, and setting triangular in shape.
Described triangle setting comprises the isosceles triangle setting.
The conducting state of described series circuit is meant that described three are opened shell protection key contacts and press the series circuit conducting simultaneously; The off-state of described series circuit is meant that described three are opened shell protection key contacts and do not press simultaneously, and series circuit disconnects.
The beneficial effect that the utlity model has: on metal keyboard button circuit board, increase by 3 and open shell protection key contacts; and open shell protection key contacts for these 3 and when being pressed, keep the series connection conducting state; only regularly in the complete state of 6 screws of EPP keyboard bottom enclosure; these 3 extra contacts just are in the state that is pressed all the time; if any one screw is by loosening; will cause 3 one in the contact to upspring; the circuit of series connection will be in off state; at this moment; the keyboard chip will the auto-destruct key and is destroyed algorithm; leaking of security informations such as metal keyboard key and key algorithm avoided in this design, ensured the fail safe of the self-service equipment of depositing and withdrawing of financial sector use.
Description of drawings
Fig. 1 is a metal encrypted keyboard schematic diagram of the present utility model.
Fig. 2 opens the schematic diagram of shell protection key contacts for the keypad portion skin of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the key diagram of metal encrypted keyboard 20.
1 is digital button, and comprising numerical key " 0-9 ", decimal point ". " and two zero key " 00 " are used to input numerals such as the password and the amount of money.
2 is cancel button, is used in operating process cancellation operation.
3 for the corrigendum button, is used to revise the password of inputing by mistake and the amount of money of withdrawing the money.
4 is ACK button, the affirmation operation behind be used to the to be totally lost password and the amount of money of withdrawing the money.
5 for reserving button, and the functions expanding that is used for the daily record keyboard is standby, is commonly used in now metal keyboard input key, uses when needing input alphabet, when for example needing input " A ", then needs to click this button, clicks " 1 " key again, just can realize.When needing input " A-F ", reserve button and just can realize in conjunction with " 1-6 " successively.
More than the composition and the function of metal encrypted keyboard is illustrated, further specify the effect that skin is opened shell protection key contacts below.
Fig. 2 is the outer key diagram of opening shell protection key contacts.
6 is keyboard shell screw fixed position behind, wherein one has 6, plays when keyboard front and back shell is completely fixed, and makes 3 additional metal key contacts on the keyboard can be in the state of pressing all the time.
7 is the keyboard contact, carries out the function of each button correspondence by key contacts.
8A, 8B, 8C are for opening shell protection key contacts; by increasing this 3 key contacts; by after loosening, any 1 in 3 key contacts will be bounced at any 1 screw on the keyboard case, and the keyboard chip will the auto-destruct key and destroyed key algorithm.
On metal keyboard button circuit board, increase by 3 and open shell protection key contacts; and open shell protection key contacts only when being pressed simultaneously for these 3; just keep the series connection conducting state; only regularly in the complete state of 6 screws of metallic bond tray bottom shell; these 3 extra contacts just are in the state that is pressed all the time; if any one screw is by loosening; will cause 3 one in the contact to upspring; the circuit of series connection will be in off state; at this moment, the keyboard chip will auto-destruct key and destruction key algorithm.
Open shell protection key contacts by increasing metal keyboard key; avoid leaking of security informations such as metal keyboard key and key algorithm; ensured that financial institution uses the fail safe of the self-service equipment of depositing and withdrawing, made this metal button when carrying out cash and non-cash transaction, more safe and reliable.
