The locking member 110 has an outer frame 111 and an inner structure 113. The outer frame 111 has a quadrangular frame shape, and two pairs of locking holes 111a and 111b are formed in the upper wall and the lower wall, respectively. The outer frame 111 has a rectangular frame shape corresponding to the shape of the USB port 10 and is inserted into the USB port 10 and coupled thereto. The two pairs of locking holes 111a and 111b are portions to which the locking pieces 11 installed in the USB port 10 are coupled when the locking member 110 is inserted into the USB port 10. These locking holes 111a and 111b are arranged to be engaged with the locking piece 11 in two stages in the direction of engaging and disengaging the locking member 110 so that the locking member 110 can be easily detached from the USB port 10 You can not. The locking holes 111a and 111b are formed in the upper and lower portions of the lock member 110, respectively.

Also, a locking hole 111c may be formed on a side surface of the outer frame 111. [ The locking hole 111c is resiliently coupled by a locking piece (not shown) provided on the inner side surface of the USB port 10 to prevent the locking member 110 from being easily separated from the USB port 10.

In addition, a locking piece 113d (see FIG. 1B) may be formed on the side of the outer frame 110 in place of the locking hole 111c. The locking piece 111d elastically contacts the inner side surface of the USB port 10 when the USB port 10 is coupled to the USB port 10 so that the locking piece 110d can not be easily separated from the USB port 10.

The inner structure 113 is inserted into the outer frame 111 to be coupled thereto. The internal structure 113 is coupled to the USB port 10 so as to open a part of the USB port 10 to provide a space for relatively inserting the connection pin 12 into the rear of the external frame 111. The inner structure 113 blocks the front of the outer frame 111 while leaving only the keyhole 113a in which the fixed key 123 of the releasing key unit 120 is inserted at the front of the outer frame 111 And has a combined configuration.

A key protrusion 113b is formed in the keyhole 113a in a predetermined pattern to allow a predetermined fixed key 123 to be coupled to the keyhole 113a.

As shown in FIG. 5, when the locking member 110 having the above configuration is inserted into the USB port 10, the locking member 110 is completely inserted into and coupled to the USB port 10, and thus is removed using the release key unit 120. Since it cannot be easily removed by other methods, the USB port 10 can be physically and safely blocked.

The release key unit 120 is for separating the locking member 110 coupled to the USB port 10 as shown in FIG. 5 from the USB port 10 in a coupled state as shown in FIG. 4. The release key unit 120 includes a unit body 121, a keyhole 122 rotatably installed on the unit body 121, a fixed key 123 coupled to the keyhole 122, a fixed key 123 And a release button 125 provided on the key holder 122. The release button 125 is provided on the key holder 122,

A receiving portion 121a for receiving a plurality of locking members 110 is formed in the unit body 121. The receiving portion 121a includes a cover member 121b slidably mounted on the unit body 121, .

One end of the key holder 122 is rotatably mounted on the unit body 121.

A fixed key 123 protrudes from the keyhole 122 at the other end. The fixed key 123 is inserted into the keyhole 113a of the lock member 110 and a keyway 123a corresponding to the key projection 113b in the keyhole 113a is formed at the tip. Therefore, only when the fixing key 123 having the key groove 123a corresponding to the key protrusion 113b is inserted into the key hole 113a, the fixing key 123 and the latch key 124 are completely inside the key hole 113a. The latch key 124 may be inserted into the key hole 113a.

As shown in FIGS. 6A to 6D, the clasp key 124 has a substantially U-shape in planar configuration, as long as it extends from the elastic portion 124a connected to one end thereof and the elastic portion 124a. A locking step 124c is provided at the free end of the pair of connecting portions 124b. In addition, a button contact portion 124d which is interfered by the release button 125 is provided at the center of the connection portion 124b. In the latch key 124 having the above configuration, when the release button 125 is pressed in the state shown in FIGS. 6A and 6B, the button contact part 124d is pressed by the release button 125, and thus, the latch key 124 is different from FIGS. 6C and 6D. As the gap between the pair of connecting portions 124b is narrowed, the locking jaw 124c is positioned so that it can be pulled out without being caught inside the key hole 113a.

According to the USB port locking apparatus 100 having the above-described configuration, the locking member 110 is inserted into the unused USB port 10 of the electronic apparatus 10 such as a computer. Then, the locking member 110 is completely inserted into the USB port 10 to prevent the locking hole 111b from being caught by the locking piece 11 and naturally falling out to the outside. Of course, before the lock key 113a is forcibly pulled out by inserting the lock key 123 and the latch key 124 of the release key unit 120, it becomes difficult to easily pull it out by using another tool or the like. Therefore, it is possible to physically block the connection of the USB memory 10 to the USB port 10 by an intruder or an intruder who intrudes into a government agency such as a company or a government office, thereby preventing virus infiltration and preventing leakage of important information can do.

In particular, in the case of the present invention by forming a pair of locking holes (111a, 111b) in the locking member 110, by having a configuration formed in plurality so as to neighbor in the direction to be coupled and separated with respect to the USB port 10, The locking member 110 is firmly supported by the locking piece 11, and in particular, is subjected to frictional force over two steps, so that the locking member 110 can be easily prevented from falling out. In addition, due to the pair of locking holes 111a and 111b, when the locking member 110 is separated, the frictional force is applied to the secondary, so that it cannot be easily separated except forcibly pulling out by using the release key unit 120. .
