Abstract

The utility model provides a USB (universal serial bus) port external-connection-proof charging-proof and secret-leakage-proof three-proof lock, which comprises a casing, wherein one end of the casing is provided with a USB external connection jack, a circuit board is arranged in the casing, the USB jack is connected with the circuit board, and the other end of the casing is provided with a data wire connected with the circuit board. The USB port external-connection-proof charging-proof and secret-leakage-proof three-proof lock has the advantages that the USB data output port can maintain the connected or disconnected state with a system, the USB data communication is in a controlled state, nonpermissive personnel can be prevented from using intranet computers without authorization, meanwhile, the secondary prompt is carried out on operators through the computer software interface, and the misoperation is prevented.

Description

USB mouth is anti-to be outreached, anti-charging, the anti-Three-protecting lock of divulging a secret
Technical field
The utility model relates to USB interface control device, is specifically related to that a kind of USB mouth anti-outreaches, anti-charging, the anti-Three-protecting lock of divulging a secret.
Background technology
Along with scientific and technological development, USB interface is widely used by people.Because USB interface communication is smooth and easy, easy to use, the equipment with USB interface is more and more.At present, the computing machine that people use has several USB interface, and existing computing machine USB interface is used mostly without restriction.Along with the raising of people's safety, confidential notions, in some crucial industries, as high industries of some confidentialities such as national defence, electric power, banks, very strict to the request for utilization of computing machine, non-designated personnel can not arbitrarily use certain computer.Therefore, the control to USB interface of computer and important, can prevent that other staff from reading the critical data on computing machine by USB interface, especially Intranet data.
Summary of the invention
Technical problem to be solved in the utility model is how to make the USB interface of computing machine obtain effective management and control, prevents that a kind of USB mouth of unwarranted librarian use from anti-outreaching, anti-charging, the anti-Three-protecting lock of divulging a secret.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of USB mouth is anti-to be outreached, anti-charging, the anti-Three-protecting lock of divulging a secret, comprise housing, establish USB circumscription socket in one end of housing, in housing, establish a circuit board, USB socket is connected with circuit board, establishes the data line being connected with circuit board at the other end of housing; On described circuit board, establish microprocessor controller, microprocessor controller is connected with USB circumscription socket, USB High-speed on-off control, and USB speed-sensitive switch is connected with usb data delivery outlet.
Could to use USB interface in order clearly showing, to establish a double-colored LED light on described housing, dual-colored LED pilot lamp is connected with circuit board.
The utility model adopts that the designed USB mouth of technique scheme anti-ly outreaches, anti-charging, the anti-Three-protecting lock of divulging a secret ,owing to establishing circuit board in housing, by circuit board microprocessor controller control USB speed-sensitive switch, make usb data delivery outlet and system can keep being connected or disconnecting, usb data communication is in slave mode, avoid non-license personnel to use without permission inner net computer, meanwhile, can also carry out secondary prompting to operating personnel by computer software interface, prevent maloperation.
Brief description of the drawings
Fig. 1 represents structural representation of the present utility model;
Fig. 2 represents the square frame principle schematic diagram of the utility model circuit control;
Fig. 3 represents use process flow diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing to the utility model USB mouth anti-outreach, the structure of anti-charging, the anti-Three-protecting lock of divulging a secret illustrates.
Referring to Fig. 1, the utility model USB mouth is anti-to be outreached, the structure of anti-charging, the anti-Three-protecting lock of divulging a secret comprises a plastic casing 2, USB circumscription socket 1 is established in an end at plastic casing 2, in plastic casing 2, establish a circuit board 4, USB circumscription socket 1 is connected on circuit board 4, establishes the data line 5 being connected with circuit board 4 at the other end of plastic casing 2.In the time connecting computing machine, first stay next computing machine USB mouth to be used for carrying out exchanges data, then remaining USB mouth is all carried out to shutoff, make computing machine outbound data transmit port unique.Referring to Fig. 2, wherein, on circuit board 4, establish microprocessor controller, microprocessor controller is connected with USB circumscription socket, USB High-speed on-off control, and USB speed-sensitive switch is connected with usb data delivery outlet.The utility model makes usb data delivery outlet and system can keep being connected or disconnecting by the microprocessor controller on circuit board 4, and usb data communication, in slave mode, avoids non-license personnel to use without permission inner net computer.The utility model is also made a password confirming and alarm system by means of computer software, and soft or hard combination realizes the effective management and control to USB interface of computer.Could use USB interface in order to clearly show, on plastic casing 2, establish a double-colored LED light 3, dual-colored LED pilot lamp 3 is connected with circuit board 4, default is worked as dual-colored LED pilot lamp 3 and is shown that red interval scale USB mouth is disabled status, when dual-colored LED pilot lamp 3 shows the release of green interval scale USB mouth, can use.
Referring to Fig. 3, the utility model in use, first will be inserted on USB circumscription socket 1 with the interfacing equipment of USB, start system password input window, input system when correct when password (password has been input in computing machine in advance) and can send twice warning, reminding user is anti-to be outreached, anti-charging, anti-divulging a secret, and then brings into use USB interface to carry out data processing.In the time of Password Input mistake, system exits automatically, and USB interface is in off-state, and data communication is obstructed, can not access data, reach effective management and control, and prevent leaking of security information.
