Embodiments of the invention disclose a USB female end, a USB male end and a USB port connection device. The USB female end comprises a female end body (1) which comprises a receptacle (11), two solenoid switches (3), a switch, a signal acquisition unit (21) and a control unit (22). Each solenoid switch (3) controls a movable core (31) to protrude and pass through the through hole on side walls of the receptacle (11). The signal acquisition unit (21) generates a corresponding potential signal from potential information. The control unit (22) controls the switch to enable or disable the power supply of the solenoid switches (3). When the USB female and the USB male are connected, the movable cores (31) pass through the through holes and lock the USB male, thereby improving the firmness of the connection between the USB female end and the USB male end. |
