A kind of tamper Internet bank token
Technical field
The utility model relates to a kind of Internet bank token, is specifically related to a kind of tamper Internet bank token.The field that belongs to Internet bank's safety.
Background technology
Along with networks development, the Internet bank is accepted by most of people.The Internet bank uses the token of the Internet bank in a large number, stores lot of data in the token of the Internet bank, if usurped by others, will produce serious consequence.
So proposed the problem of security protection of the token of the Internet bank.
The utility model content
The purpose of this utility model is, provides a kind of tamper Internet bank token, to overcome the above-mentioned shortcoming and defect of existing in prior technology.
A kind of tamper Internet bank token comprises fuselage, bonnet and circuit board, and described fuselage and bonnet are connected, and described fuselage interior is provided with circuit board, it is characterized in that, elastic sheet switch and contact are set on the described circuit board, and described elastic sheet switch is connected with the contact;
Described elastic sheet switch comprises: head, middle part and afterbody, and described head is fixed on the circuit board, and described head is connected with the middle part of arching upward, and described middle part and bonnet touch, and described afterbody and contact touch.
Wherein, described head is set to horizontally disposed domes, on described head welding and the circuit board.
Wherein, described middle part is set to domes, and the quantity of described domes is one.
Wherein, described afterbody is set to convex structure.
Principle of the present utility model:
Fuselage interior is provided with circuit board, and elastic sheet switch is set on the circuit board, and in the head welding and circuit board of elastic sheet switch, arching upward in the middle part of elastic sheet switch, when building bonnet, touches with bonnet, accepts the pressure of bonnet, and the compressing middle part drives the tail down campaign.The contact that is provided with on afterbody and the circuit board touches.Circuit communication.
When dispatching from the factory, when the bonnet of token and fuselage were closed, elastic sheet switch was a closure state, and circuit is a connected state.
When the people attempted to open, the bonnet of token and fuselage did not have closed the time, and elastic sheet switch is a free state, and circuit is for disconnecting, and product automatically resets at this moment, and all data can't read.
The beneficial effects of the utility model:
The utility model is provided with elastic sheet switch on circuit board, when the bonnet of token and fuselage were opened, elastic sheet switch was a free state, and circuit is for disconnecting, and product automatically resets at this moment, and all data can't read.Data in the token are protected, played tamper, the anti-effect that reads and prevent duplicating, guaranteed the safety of the token of the Internet bank.
What the afterbody of elastic sheet switch was set to circular-arc, circular-arc afterbody can guarantee shell fragment effective contact point and guarantee that shell fragment can carry out deformation swimmingly when bonnet is oppressed shell fragment still when highly slightly changing.

Reference numeral:
Fuselage 100, bonnet 200, circuit board 300, contact 310, elastic sheet switch 400, head 410, middle part 420, afterbody 430.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be understood that following examples only are used to the utility model is described but not are used to limit scope of the present utility model.
A kind of tamper Internet bank token as shown in Figure 1, comprises fuselage 100, bonnet 200, circuit board 300 and elastic sheet switch 400.
Fuselage 100 is connected with bonnet 200, and described fuselage 100 internal edges are provided with draw-in groove, and the edge of bonnet 200 is provided with bayonet socket, and the size of draw-in groove and bayonet socket matches.
Referring to Fig. 1, fuselage 100 inside are provided with circuit board 300 once more, and elastic sheet switch 400 and contact 310 are set on the circuit board 300, and elastic sheet switch 400 can be connected with contact 310 when bonnet 200 and fuselage 100 are closed.
As shown in Figure 2, elastic sheet switch 400 comprises: head 410, middle part 420 and afterbody 430, and head 410 is set to horizontally disposed domes, and an end of head 410 is fixed on the circuit board 300, and head 410 can adopt the form of welding to be fixed on the circuit board 300.The other end of head 410 is connected with the middle part of arching upward 420, and the jut at middle part 420 and bonnet 200 touch.
Referring to Fig. 2 and Fig. 3, the middle part 420 of elastic sheet switch 400 is set to domes once more, and the quantity of domes is one.Afterbody 430 is set to convex structure, and the bottom of convex structure and contact 310 touch.
Using method of the present utility model:
When dispatching from the factory, in the time of the bonnet 200 of token and fuselage 100 closures, elastic sheet switch 400 is a closure state, and circuit is a connected state.
When the people attempted to open, the bonnet of token 200 and fuselage 100 did not have closed the time, and elastic sheet switch 400 be a free state, and circuit is disconnection, and product automatically resets at this moment, and all data can't read.
The utility model is provided with elastic sheet switch 400 on circuit board 300, when the bonnet 200 and the fuselage 100 of token was opened, elastic sheet switch 400 was a free state, and circuit is for disconnecting, and product automatically resets at this moment, and all data can't read.Data in the token are protected, guaranteed the safety of the Internet bank.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.
