USB (Universal Serial Bus) connector with data theftproof female interface

The invention relates to a USB (Universal Serial Bus) connector with a data theftproof female interface. The USB connector provided by the invention comprises a shell, wherein a faucet is arranged at the front end of the shell; an insulator and a corresponding contact element are arranged in the shell; an insertion-connection channel is formed between the outer surface of the insulator and the inner wall surface of the shell; and the insulator is provided with more than one theftproof stop dog protruded from the insulator toward the inside of the insertion-connection channel. Because the thefproof stop dog is arranged on the insulator, thus the USB connector with the data theftproof female interface is in stopping block fit with the common USB connector in the current market when the common USB connector is to be inserted in the USB connector with the data theftproof female interface so that the common USB connector can not complete connection, thus the data information in a computer is effectively protected,
