Slide to the second step faces 533, 543, respectively. The positioning post 6 is pushed up to compress the second elastic member 56, so that the distance between the positioning post 6 and the mating surface is shortened, and the overall southness is shortened after the docking. After the docking state is eliminated, the cylinder 6 is restored by the elastic action of the second elastic member 56, and the first stopper 53 and the second stopper 54 are restored to the initial state under the elastic force of the first elastic member 55. The connecting portion of the first stopper can also be a separate component, and the same effect as the foregoing embodiment can be achieved by simultaneously arranging the receiving grooves on the respective stoppers. As shown in Figs. 9(a) and 9(b), in the electrical connector 3 of another embodiment, the connecting portion is even eliminated, and the first elastic member 53 is directly sleeved on the first stopper W.
