An electrical connector assembly comprises a first connector having an outer housing having an activatable latch flexibly attached thereto, the latch having a lock tab located thereon; an inner housing mounted in the outer housing, the inner housing having first and second prongs integrally formed with the inner housing and configured to continuously bias the latch; and a second connector comprising a cavity formed on a surface thereof. Continuously biasing the latch by the first and second prongs causes the engagement of the lock tab of the first connector with the cavity of the second connector to lock the first connector to the second connector.
