US Patent 7442066 Plug connector

A plug connector includes an insulating housing, a plurality of terminals and two latches. The insulating housing has a base and a tongue portion protruding forward from the front of the base. The terminals are received in the insulating housing. Two cavities are defined at two sides of the base and the tongue portion for receiving the respective latches. Each of the latches has a fixing portion. The fixing portion extends forward and inclines downward to form a first elastic arm. A free end of the first elastic arm extends forward and inclines upward to form a second elastic arm. The second elastic arm protrudes upward to form a hook at a free end thereof and a support portion lower than the hook at the rear of the hook. The hook and the support portion stretch out of the cavity to rise above the tongue portion.
