Plug electrical connector

Claim 1

A plug electrical connector comprising: a dielectric base having two opposite side walls each defining a slot therein; an insulative housing receiving a number of contacts therein and being received in the base and between the two opposite side walls; a cable extending into the base from a rear end thereof and having an electrical connection with the contacts; a pair of latching members each having a retaining arm fixedly received in a corresponding slot, a lock arm located above and resiliently movable toward the retaining arm and having a barb at a free front end thereof for engaging with a mating connector, a tab extending first upwardly from the lock arm and then inwardly toward the housing, said tab forming an abutment at its upper end; and a cover fixed to the base and having a movable operating portion engaging with the abutments, whereby when the operating portion is depressed downwardly, the lock arms and the barbs move downwardly; wherein the abutment of each latching member extends straight upward; wherein a slit is defined between each lock arm and the corresponding retaining arm; wherein a pair of latching projections depends downwardly from opposite sides of a rear portion of the cover to latch in a pair of holes defined in opposite sides of a rear portion of the base; wherein a strain-relief block is integrally formed at an end of the cable for preventing the cable from being pulled out of the electrical connector by an overload force; wherein a pair of guiding posts extends forwardly from front ends of the side walls of the base for guiding the plug electrical connector to mate with the mating connector.
