An electrical cable connector includes a case forming a front receiving cavity, and a rear receiving cavity. An upward room is formed in an upper face of the case. A latch is pivotally mounted in the room with an upward locking hook at a front end thereof in an up-and-down moveable manner. An actuator is engaged with the latch to actuate the latch to be unlatched from the locking hole in the cage via a rearward pulling. An engagement between the latch and the actuator is performed by a latch slot in the latch and a T-shaped lug on the underside of the actuator moving along the latch slot. A curve structure is formed on the latch along a front-to-back direction so as to have the latch to be pivoted during rearward pulling the actuator, thus having the upward locking hook downward moved for unlatching.
