Description

Card insert type mechanical cipher controller

The utility model relates to a kind of Crypto Control Unit, especially relates to a kind of mechanical cipher controller of card insert type.

Existing security personnel's product mainly contains lock class and burglar alarm etc.The lock class is divided into mechanical lock and magnetic electron lock again, the mutual opening rate height of mechanical lock class, and theftproof performance is undesirable.The mutual opening rate of magnetic electron lock is lower, but the same with mechanical lock, its key is easy to duplicate, so anti-theft effect is also undesirable.

For overcoming the deficiency of above-mentioned lock class security personnel product, people have proposed cipher control lock etc. again.The controller subdivision of this kind cipher control lock is an electronic product, and therefore, it all can have information exchange with the external world more or less.By this information, the burglar can decode the password of this controller, thereby makes this coded lock completely lose protection function.The coded access device that some coded lock electronic controllers such as bank are also arranged, it need not to send the electronics electronic information to the external world.After keyboard or other peripheral hardwares are received the password of input, directly judge, if password is errorless, then open; If password bad, then can report to the police or make corresponding actions.Obviously, the cost of this electronic cipher controller is very high.

For overcoming the deficiency of Electronic Control Crypto Control Unit, the someone proposes the Crypto Control Unit of machinery control again, and this kind mechanical code controller mainly comprises several combination disk.Each combination disk all preestablishes a password position, when all combination disk all by transferring to during the predetermined cipher position, Crypto Control Unit promptly is in opening.After shutting, need to leave combination disk under order password position, password is transferred disorderly, to prevent the generation of the incident of stealing.Go to adjust with needing a combination disk of a combination disk when this kind coded lock is operated obviously, too loaded down with trivial details.Because the adjusting of this kind Crypto Control Unit password is to adjust by the continuous rotation of combination disk,, and be difficult to whether correctly determine whether to report to the police by password so this kind Crypto Control Unit is difficult to and circuit is realized interlock.

For overcoming above-mentioned many deficiencies, utility application has proposed a kind of new-type mechanical code controller for No. 00228634.3, the good confidentiality of this kind mechanical code controller, and cost is low.But operation is trouble slightly, must press several passwords successively and just can finish whole breakdown action.

It is a kind of easy and simple to handle that the purpose of this utility model is to provide, the mechanical cipher controller of lower-cost card insert type.

For achieving the above object, the utility model adopts following technical scheme: card insert type mechanical cipher controller comprises base and plug-in card:

Described base is provided with elastic force contact, series connection contact and operating contact, and stube cable is connected between relevant contacts;

Be provided with the pressure film trap in the corresponding position of elastic force contact on the described plug-in card, partly in the pressure film trap pressure plate be set.

Understand for the utility model patent being had further, the spy is described in detail as follows with accompanying drawing in conjunction with the embodiments.

Accompanying drawing 1 is depicted as the utility model structural representation.

Accompanying drawing 2 is depicted as the utility model plug-in card structural representation partly.

Accompanying drawing 3 is depicted as the utility model plug-in card inside

Embodiment:

See also accompanying drawing 1, the mechanical cipher of card insert type shown in figure controller comprises base 1 and plug-in card 2:

Described base 1 is provided with elastic force contact 3, series connection contact 4 and operating contact 5, and stube cable 6 is connected between relevant contacts;

Be provided with pressure film trap 7 in the corresponding position of elastic force contact 3 on the described plug-in card 2, partly in the pressure film trap 7 pressure plate 8 be set.

Described cassette mechanical cipher controller, series connection contact 4 and operating contact 5 are arranged separately in pairs, keep in touch with elastic force contact 3 under 4 normalities of series connection contact, break away from elastic force contact 3 under operating contact 5 normalities.

Described card insert type mechanical cipher controller, on the base 1 with its in the pressure film trap 7 corresponding positions of pressure plate 8 are set, the input of stube cable 6 and output are connected to operating contact 5 corresponding two contacts.

Described card insert type mechanical cipher controller, on the base 1 with its in the pressure film trap 7 corresponding positions of pressure plate 8 are not set, the input of stube cable 6 is connected to 4 corresponding two contacts, contact of connecting with output.

When plug-in card 2 inserted on the base 1, pressure plate 8 compressing elastic force contacts 3 past its front ends that protract in the pressure film trap 7 contacted with operating contact 5, if stube cable 6 is to be connected in operating contact 5 on this position, then by elastic force contact 3, circuit is connected; Otherwise stube cable 6 is to be connected in the series connection contact on this position, and then because the elastic force contact breaks away from it toward protracting, circuit disconnects.Another kind of situation then is that on the position of the pressure film trap 7 that pressure plate 8 is not set, because pressure film trap 7 itself can't touch elastic force contact 3, so circuit is unaffected.

As seen, make stube cable 6 be connected in series connection contact 4 or operating contact 5 as required, in stube cable 6 is connected in pressure film trap 7 on the relevant position of operating contact 5, pressure plate 8 is set, then can make card insert type mechanical cipher controller.If in the pressure film trap 7 of pressure plate 8 should not be set pressure plate 8 was set, if in the pressure film trap 7 of pressure plate 8 should be set pressure plate 8 is not set, then entire circuit can't be communicated with, and warning circuit also is set in case of necessity.

Shown in accompanying drawing 1 and accompanying drawing 3, card insert type mechanical cipher controller among the figure, there is power switch 9 rear end of plug-in card 2, and front end has power contact 10 to link to each other with extraneous power supply.Power switch 9 is used to control the through and off of power circuit.In the process of inserting, disconnect this power supply earlier, prevent random warning.

As shown in Figure 2, card insert type mechanical cipher controller among the figure, its plug-in card 2 is provided with detachable cap 11.The pressure film trap 7 and the pressure plate 8 of 11 pairs of plug-in cards 2 of detachable cap have protective effect, and privacy functions is arranged again simultaneously.

The utility model card insert type mechanical cipher controller can be controlled the through and off of operating circuit by plug-in card 2, and then control depends on the unblanking of this operating circuit through and off, locking or other work, thereby operational motion is simple and easy to do.
