If the fastening piece 123 remains in the unit body 110 remaining in the housing port 10 while the cover body 120 is removed abnormally as described above, It is also impossible to insert the cover body 120 into the unit body 110.

Therefore, if the manager or the like subsequently pulls out the unit body 110 and finds that the fastening piece 123 is broken and remains, it is possible to recognize that an unauthorized person has attempted illegal access to the USB port. (Fig. 11B)

12 shows a process of removing the unit body 110 remaining inside the port housing 10 by using the key unit 200 of the present invention when only the cover body 120 is abnormally removed as described above.

Since the engaging protrusions 232 provided on the fixed keys 230a and 230b of the key unit 200 correspond to the engaging recesses 144 formed in the unit body 110, even when the cover body 120 is removed It is possible to remove the unit main body 110 by using the key unit 200. The detailed removal process is the same as that described with reference to FIG. 10, so that the description is omitted here.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

For example, in the above-described embodiment, the through hole 123a formed between the connecting portions 124 is formed as a long hole having a predetermined length so as to easily break the fastening piece 121. However, (123a) may be arranged in a line and formed in the same shape as a dotted line.

As another example, the engaging groove portion 144 of the unit body 110 and the engaging protrusion 232 formed on the fixed keys 230a and 230b may be variously modified in specific positions, shapes, and the like. For example, the latching groove portion 144 may be formed only on one of the inner walls of the key insertion hole 101 facing each other. In this case, the locking protrusion 232 may be formed only on the corresponding fixed key, or one fixed key may be included in the key unit 200. [

As another example, a locking protrusion may be formed on the inner wall of the key insertion hole 101 of the unit body 110, and a corresponding locking groove may be formed on the fixing keys 230a and 230b.

The movable key 240 is inserted into the key insertion hole 101 in the state where the fixed keys 230a and 230 of the key unit 200 are inserted into or between the fixed keys 230a and 230b, It is needless to say that when the lock unit 100 is brought into intimate contact with the locking unit 100,

Further, it is needless to say that, in any case, whether or not a locking groove is formed in the inner wall of the key insertion hole 101 of the unit body 110 or a locking protrusion is formed, a locking protrusion to which a clip inserted from the outside can be caught is not formed.

The present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof, and it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
