A security USB adapter of the present invention comprises: a box-shaped security block (10) inserted into a standard USB connector (U) to block insertion of a standard USB memory (UM); a plate-shaped security connecting chip (20) provided in the interior of the security block (10) and including connector terminals (21) arranged on the top surface in the same way of contact terminals (2) and security terminals (22) arranged on the bottom surface in a different way from the contact terminals (2); a security adapter (30) including an adapter plug (31) extending with a width identical to an inner width of the security block (10) and plug elastic terminals (32) arranged on the top surface of the adapter plug (31) in the same way of the security terminals (22), the arrangement of the security terminals (22) formed in the security connecting chip (20) is formed into any one arrangement pattern among 24 patterns not to be in contact with terminals of the standard USB memory (UM) such that the box-shaped security block inserted into the standard USB connector may prevent the standard USB memory from being inserted, and the arrangement of the security terminals formed in the security connecting chips is randomly changed to any one pattern among the 24 patterns to vary mutual contact positions, thereby improving security. |
