  • Patent number: 9197016
    Abstract: The present invention provides a self-ejectable port fixing device for contact connecting with a port having a port chip. The port fixing device comprises a casing having an opening through which the port chip is allowed to insert and to contact with a receptacle chip provided in the casing. The port fixing device further comprises an elastic unit and a locking unit. The elastic unit is compressed directly or indirectly by the port so as to accumulate elastic potential energy while the port chip is getting closer to the receptacle chip. When the port chip is in contact with the receptacle chip, the locking unit locks the port chip at this contacting position. When the locking unit is unlocked, the elastic unit releases the elastic potential energy to push the port chip to be detached from the receptacle chip.

  • Publication number: 20140127927
    Abstract: 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.
