20140127927 | USB MALE END, USB FEMALE END AND USB PORT CONNECTION DEVICE - 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 ( | 05-08-2014 |
20140162481 | SELF-EJECTABLE PORT FIXING DEVICE - 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. | 06-12-2014 |
