Electrical connector having a locker for enabling the connector to have a reliable connection with a mated connector

Claim 1

An electrical connector for mating with a complementary connector, comprising: a base defining a pair of elongated channels each including a stopper in opposite sides of the base; a cover assembled to the base, the base and the cover together define an enclosure for receiving a connector housing; a pull tab assembled to the base/cover assembly and having a pair of arms, each arm having a latch releasing portion at a free end thereof; a pair of latch springs cooperating with the pull tab for latching with the complementary connector, the latch releasing portions driveably connecting with the latch springs, whereby when the latch releasing portions moves the latch springs also moves in a predetermined manner; and a locker having a pressing portion and a pair of locking portions, the locker connecting with the pull tab and the locking portions abutting against stoppers to secure the pull tab on the base where the locker is at a first position; wherein when the pressing portion is moved to a second position, the locking portions disengage from the stoppers, whereby the pull tab can be moved in a first direction to cause the latch releasing portions to drive the latch springs to move in a direction for separating from the complementary connector; wherein the locker has a pair of beams extending from the pressing portion, the locking portions are formed on edges of the beams; wherein the locker has a pair of spring portions formed on the beams and abutting against the pull tab, the pressing portion moves from the second position to the first position by a spring force of the spring portions; wherein the locker has a stopper portion extending from the pressing portion and in a direction the same as the pressing portion for abutting against an upper surface of the pull tab.
