Description

USB Lock Socket Security Locker for USB Socket

The present invention relates to a USB socket security lock for a USB socket type that locks a USB socket by preventing it from falling out without a separate control command or a password when the USB socket is mounted on the USB socket.

In the field of industrial information security, much efforts have been made to prevent information stored in computers and the like from being leaked to the outside, and information leakage through the Internet has been relatively effectively prevented. However, it is very simple and easy to transfer information through a USB interface widely used in computers and the like, but its management is very difficult. For example, even if a user inserts a USB memory into a USB socket of a portable notebook and transfers special information to the notebook, the administrator can not turn on the notebook to check the files stored therein.

'USB' is a simple name for a universal serial bus (USB), which is one of the input and output standards used to connect computers and peripherals. It is a type of keyboard, mouse, printer, scanner, digital camera, storage device ) And the like. As in the previous example, the USB socket is exposed on the computer or laptop, and the USB plug is inserted into the USB socket and electrically connected.

One of the ways to move software programs or files stored on computers or laptops recently is to use USB memory extensively. Just plug the USB plug on the front of the USB memory into the USB socket that is exposed to the computer or the notebook. The computer recognizes the USB memory as a storage device and transfers the files stored on the computer etc. to the USB memory Or, conversely, files stored in the USB memory can be transferred to a computer or the like. In addition, USB plugs can be interconnected via a USB cable on the front.

A commonly used method in the industry for managing the leakage of information through the USB interface is to seal the USB socket on the person's computer with tape. If the seal is removed, it is judged that the USB interface is used and the inspection is performed. However, it can not be guaranteed that this is still well secured. For the fundamental security of the USB interface, lock the USB socket from being used.

In addition, a conventionally used USB interface lock device (for example, Patent Publication No. 10-2010-0131925) is disclosed, but these devices are intended to prevent the USB plug from being arbitrarily disconnected from the USB socket, It is not a security lock device that blocks the plugging of any plug in itself.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a USB socket security locking device for locking a USB socket by preventing the USB socket from being arbitrarily disengaged without a separate control command or a password when the USB socket is mounted on the USB socket.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail with reference to the drawings.

1 to 4, a locking device 100 for locking a USB socket security device according to the present invention has a USB plug type, When the socket 10 is inserted into the USB socket 10, the user can not use another computer peripheral device, such as a memory device, by inserting the socket 10 into the socket 10.

The lock device 100 operates in a socket lock mode and a socket open mode, and the entry of each mode is controlled by a lock control section 233 described below. The socket locking mode is a state in which the socket 10 is not opened and thus the socket 10 can not be connected to the USB memory or other peripheral device and the user can freely disconnect the locking device 100 from the socket 10 Can not. In the socket open mode, the locking device 100 is detachable from the socket 10 so that the user can detach the locking device 100 from the socket 10 and use the socket 10.

2, the locking device 100 basically has a plug shape to be fitted into the socket 10 and includes a locking part 210 for the present invention and a locking part case 221 for accommodating the locking part 210 ).

The lock portion case 221 is wrapped and protected by a plug case 223 and a body cover 225 in the form of a plug. When the locking device 100 is inserted into the socket 10, the plug case 223 is inserted into the socket 10 in such a manner as to fit in the space portion 15 inside the socket 10. At this time, the plug case 223 is provided with a through groove 223a through which the latching leaf spring 11 of the socket 10 is inserted and engaged with each other. The coupling of the latching leaf spring 11 and the through groove 223a is well known and has a coupling force enough to be easily separated by a small force of the user. In the example of Fig. 2, the through-hole 223a functions as a catching groove 223a described below.

The lock portion case 221 is formed therein with a lock member receiving portion 227 in which the lock portion 210 is received. 2, the lock portion case 221 covers the upper portion of the lock member accommodating portion 227 and the lower portion of the lock member accommodating portion 227 covers the plug case 223 and the body cover 225 .

2, the lock part case 221 serves as a terminal block for supporting the electric terminal 229 like a conventional USB plug and is supplied with power from the computer 20 or the like equipped with the socket 10 But it is not an essential function of the present invention.

The locking portion 210 basically includes a locking member 201 serving as a locking latch. The locking member 201 can be formed as a flat plate as in the example of Fig. 4 and includes a hinge portion 201a for rotating the locking member 201 and a hinge portion 201b for extending from the hinge portion 201a to the front end of the locking device 100 And a latch 201b which is bent in a downward direction at an end portion exposed to the outside through the latch groove 223a of the plug case 223. Therefore, the lock member 201 can rotate the latch 201b at a predetermined angle in the lock member receiving portion 227 around the hinge portion 201a.

When the lock member 201 is heavy in weight on the side of the latch 201b with respect to the hinge portion 201a and is in a state of no operation other than the opposite side, Is always exposed through the opening 223a. The degree of exposure of the latch 201b to the outside of the latch groove 223a does not need to be large enough so that it is sufficient that it is approximately 1 mm to 3 mm and it is possible to lock it without any special operation when inserted into the socket 10 Preferably about 1 mm. When the socket is in the socket lock mode, the latch (201b) is fitted into the coupling groove (13) of the socket (10), so that the socket (10) is locked.

The through groove 223a through which the latching leaf spring 11 of the bottom surface of the socket 10 is inserted can be used as the latch groove 223a in which the latch 201b is exposed. The coupling groove 13 formed in the socket 10 may also be formed by cutting the lower surface of the socket 10 to generate the leaf spring 11 for latching. The locking member 201 can be arranged to be biased to one side from the center of the locking device 100, opposite to the latching leaf spring 11 of the socket 10. [

2, the lock portion 210 includes a press plate 201c which is bent at a predetermined angle from the hinge portion 201a and formed at the other end of the lock member 201 extending in the direction opposite to the latch 201b, And an elastic member 203 for elastically supporting the pressure plate 201c. When the pressing plate 201c is formed in the lock receiving portion 227 according to the shape of the lock member 201, the lock portion 210 is exposed to the outside of the body cover 225 to press the pressing plate 201c And a switch 205 capable of performing a predetermined operation.

<Basic operation explanation>

Hereinafter, the operation of the lock portion 210 will be briefly described with reference to FIGS. 2 and 3. FIG.

The latch 201b is exposed to the outside of the latch groove 223a in a normal state without any other operation and is more so because the elastic member 203 supports the pressure plate 201c in the example of FIG. When the lock device 100 is inserted into the socket 10, when the push plate 201c is pressed using the switch 205 as shown in Fig. 3, the latch 201b rotates about the hinge portion 201a, So that the locking device 100 can be mounted to the socket 10 without any hitches. Thereafter, when the pushing operation of the switch 205 is stopped, the position of the switch 205 and the lock member 201 is restored by the restoring force of the elastic member 203, and the latch 201b is returned to the outside of the latch groove 223a Exposed and locked in the coupling groove 13 of the socket 10 to be locked.

When the lock device 100 is mounted on the socket 10 and the latch 201b is fitted in the lock groove 13, when the push plate 201c is pressed by using the switch 205 and the lock device 100 is pulled out, The locking device 100 is easily separated from the socket 10.

If the degree of exposure of the latch 201b is small, when the locking device 100 is inserted into the socket 10, the latch is lifted by the case of the socket 10 even if the switch 205 is not pressed, And can be coupled to the coupling groove 13. However, if the push plate 201c is not pressed by using the switch 205, the locking device 100 is not separated from the socket 10. [

In the socket lock mode, the locking device 100 should not be disconnected from the socket 10, even if there is an arbitrary operation of the user, for example, the operation of the switch 205. The locking portion 210 of the locking device 100 of the present invention is moved in the turning radius region of the locking member 201 A locking member 231 for blocking the pressing operation of the pressure plate 201c by being fitted in the lock plate 201c and a lock control unit 233 for controlling the operation of the lock device 100 as a whole.

The lock control unit 233 controls the socket locking mode and the socket opening mode in such a manner that the fixing member 231 is conveyed along a predetermined conveyance path. The lock control unit 233 operates according to a predetermined control command, and such a control command can be provided through an external device. For example, when the plug terminal 229 is electrically connected to the electrical terminal 17 of the socket 10 on the upper surface of the lock portion case 221, the lock control portion 233 controls the operation of the socket- A predetermined control command may be provided from the control unit 20 and the like. In another embodiment, the locking device 100 may be provided with a separate interface to receive a software key such as a password for releasing the socket locking mode, or receive a control command from an external device other than the computer 20 .

To enter the socket lock mode, the lock control unit 233 transfers the fixing member 231 located in the fixing member storage box 239 to the lock position. Thereby, the pushing operation of the pressure plate 201c is interrupted, and the lock is not released even by the operation of the switch 205 of the user. 4 and 5, the fixing member 231 is positioned below the pressing plate 201c and the lower portion of the locking member 201 extending from the pressing plate 201c to the hinge portion 201b is shown as the 'locking position'. However, As described above, since it is the rotating radius region of the locking member 201, any place for preventing the rotation of the locking member 201 is possible.

In order to enter the socket opening mode, the lock control unit 233 causes the fixing member 231 to escape to the fixing member storage box 239 again. 2 and 3 show a state in which the fixing member 231 is in the socket release mode in which the fixing member 231 is housed in the fixing member storage box 239. Figure 4 shows a state in which the fixing member 231 is positioned at the locking position of the locking member 201, 201c in the socket lock mode.

The fixing member 231, which is illustratively shown in Figs. 2 to 4, is shown in the form of a cylinder, but is not limited thereto. Furthermore, various methods and configurations can be applied to the transporting mechanism and the mechanism of the fixing member 231.

For example, in order to complete the feeding of the fixing member 231 with a simple structure and operation, the locking device 100 of the present invention implements the fixing member 231 with a magnetic body in which N pole and S pole are fixedly arranged. The lock control unit 233 includes an electromagnet 235 for determining the polarity toward the fixing member 231 in accordance with the direction of the supplied DC power and a circuit unit 237 for controlling the operation of the electromagnet 235. The electromagnet 235 is located at the end of an imaginary line segment passing through the lock position starting from the fixed member storage box 239 and drives the electromagnet 235 in the socket lock mode to move the fixed member 231 are pulled by the pulling force to be positioned at the locked position to block the rotation operation of the lock member 201 and the pushing operation of the pressure plate 201c and to drive the electromagnet 235 in the socket release mode, Is pushed to the fixing member storage box 239 to enable the rotation of the lock member 201 and the pressing operation of the pressure plate 201c.

Further, when the plug terminal 229 is electrically connected to the electrical terminal 17 of the socket 10 on the upper surface of the lock part case 221, the lock control part 233 controls the operation of the computer 10 on which the socket 10 is mounted The electromagnet 235 can be controlled by the power source of the lamp 20. Naturally, the locking device 100 may also include a built-in battery for operating power of the lock control unit 233.

<Examples>

The locking portion 210 may further include a stopper 241 for blocking the conveyance of the fixing member 231 on the conveying path of the fixing member 231. [ The stopper 241 has a structure in which a rigid body (for example, a ball bearing) is accommodated in the groove formed on the conveying path of the fixing member 231 while being supported by the elastic member, and one end thereof is exposed on the conveyance path, (231). Therefore, even when the electromagnet 235 does not operate because the operation power of the lock control unit 233 is shut off or turned off, the fixing member 231 can be prevented from moving out of its position for reasons such as inclination. In other words, the stopper 241 prevents the socket lock mode from being arbitrarily released even when there is no operation power of the lock control unit 233.

The resistance of the stopper 241 must be smaller than the force of the electromagnet 235 to which the fixed member 231 is to be fed and the rigid body of the stopper 241 is a ball bearing so that the fixed member 231 can be slid desirable.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
