Abstract: An electrical connector assembly and its female end connector, wherein the electrical connector assembly also has a male end connector, and the female end connector can exert force on the male end connector on the long side to force the male connector to abut the female connector laterally to provide a stop and at least limit the degree of lateral displacement of the male end connector relative to the female end connector. In addition, the female connector can choose to exert force on the male connector on the long side, forcing the male connector to abut the female connector longitudinally, so as to ensure that the overlap relationship between the male connector and the female connector meets expectations , the conductive structure in the male end connector can be electrically connected to the female end connector. Furthermore,the female end connector can be buckled with the male connector on the short side to at least limit the degree of displacement of the male connector relative to the female connector, and solve the problem of insufficient mating force between the male end connector and the overlapping female end connector after the overall height is reduced. In this way, the present invention can achieve the purpose of reducing the overall size of the electrical connector assembly, so as to provide a thinner electronic product for use.
