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 fixed key 123 having the key groove 123a corresponding to the key projection 113b is inserted into the key hole 113a, the fixed key 123 and the catch key 124 are completely inserted into the key hole 113a So that the locking tab 124a of the latch key 124 can be engaged with the locking groove 113e in the keyhole 113a.

9 to 12, the latch key 124 has an elastic portion 124b having a substantially U-shaped planar configuration and connected at one end thereof, and an elastic portion 124b extending from the elastic portion 124b At the free end of the pair of connecting portions 124c, a latching protrusion 124a is provided. The latching jaw 124a is bent at an angle of about 90 degrees upward at the free end of the connecting portion 124c and is formed to protrude from the upper surface of the fixed key 123. [

 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. 9 and 10, when the release button 125 is depressed, the release button 125 pushes the button contact portion 124d. As a result, the catch key 124 of the above- The distance between the pair of connecting portions 124b is narrowed and the engaging protrusion 124c is exposed to the side surface of the fixed key 123 and enters the receiving groove 123b formed on the side surface of the fixed key 123. [ 14, when the locking key 123 is inserted into the keyhole 113a, when the locking key 123c is not protruded from the side surface of the fixed key 123 and is located in the receiving groove 123b, The engaging step 124a protruding from the upper surface of the first stepped groove 123 can be inserted into the keyhole 113a by being positioned in the second stepped groove 113c without being caught by the ceiling face s2 of the first stepped groove 113b do.

When the release key unit 120 is pulled in this state, And naturally escapes from the USB port 10.

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, so that the locking hole 111b is caught by the locking piece 11 and can be prevented from being naturally released 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.

Particularly, in the case of the present invention, a pair of locking holes 111a and 111b are formed in the lock member 110, and a plurality of locking holes 111a and 111b are formed so as to be adjacent to the USB port 10 in the direction of being engaged and disengaged. The locking member 110 is firmly supported by the locking piece 11 and can be supplemented so as not to be easily detached because it is subjected to frictional force in two steps in particular. When the lock member 110 is detached due to the pair of locking holes 111a and 111b, it is subjected to a frictional force for a second time and can not be separated easily except for the operation of forcibly withdrawing by using the release key unit 120 .

Further, since the locking groove 113e, to which the locking step 124a of the latch key 124 is locked, is formed on the ceiling surface inside the key hole 113a, Since it is difficult to forcibly pull out the member 110, it is necessary to use the designated release key unit 120 in order to pull out the lock member 110, so that the USB port 10 can be securely locked to protect information .
