In addition, as the locking member 400 exits the link unit 200, the second interference member 440 moves to a position that interferes with the locking member 271 of the third locking unit 270.

Since the second locking unit 260 is in the unlocked state, the USB cable lock housing 300 may be detached from the link unit 200, and then the USB cable 10 may be detached from the external USB port 230. . In this case, since the locking member 271 is interfered with the second interference member 440, the locking member 271 may not enter the external USB port 230.

In addition, when the locking member 400 is pushed back into the link unit 200 while the USB cable 10 and the USB external lock housing 300 are separated from the link unit 200, the link unit 200 is electronically connected. It is coupled to the USB port 21 of the device 20 to maintain a blocked state. In addition, the locking member 271 that is interfering with the third interference member 270 enters to protrude into the external USB port 230 by the elastic force of the elastic member 273. Therefore, in this state, it is not possible to connect an external device such as an unauthorized USB cable 10 or a USB memory, thereby fundamentally preventing the unauthorized external device from being connected to the electronic device 20.

While the invention has been shown and described in connection with preferred embodiments for illustrating the principles of the invention, the invention is not limited to the construction and operation as shown and described. Rather, those skilled in the art will appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
