Electrical connector having an automatically recoverable pull tab and latches

An electrical connector assembly comprising:

• a base having a mating frame formed on a front portion thereof, a pair of cylindrical posts extending upwardly from the base near the front portion;
• a connector subassembly assembled to the base and having a portion extending into the mating frame and having a plurality of terminals received therein;
• a cover assembled to the base;
• a pull tab mounted on the base and having a pair of latch releasing portions, the pull tab being movable in front-to-back direction;
• a pair of latches each having a body portion, a claw portion formed at a front end of the body portion, and a pair of sloping legs extending inwardly from rear end of the body portion, the sloping legs each having a coiled portion at a free end thereof, the coiled portions enclosing a corresponding post posts of the base therein, when the pull tab is pulled backwardly, the latch releasing portion pushing the latches to rotate in respect to the posts of the base
• wherein the pull tab has an operation portion and a pair of arms extending from a pair of ends of the operation portion, the latch releasing portions are formed at free ends of the arms, a pair of stoppers protruding from inner sides of the arms,
• wherein the base defines a pair of slits and a pair of metal springs received therein, each metal spring has a spring portion abutting against the stopper of the pull tab, when the pull tab is pulled, the metal springs are elastically deformed by the stoppers,
• wherein the pull tab has a pair of latch pushing blocks formed at rear sides of the latch releasing portions, after the pull tab is released, the pull tab moves forwardly by the metal springs and the latch pushing blocks push the latches to original positions.
