Electrical connector and electronic device

An electrical connector adapted to be electrically connected with a mating terminal includes an outer housing, an inner housing, and an elastic terminal. The outer housing includes an outer cylindrical body, and an upper blocking disc and a lower blocking disc radially extending inwardly from opposite ends of the outer cylindrical body, the upper blocking disc has an outer through hole. The inner housing includes an inner cylindrical body and a mounting portion surrounding an outer periphery of the inner cylindrical body. The inner housing is formed with an inner through hole. The mounting portion is movably mounted in a space defined by the outer cylindrical body, the upper blocking disc, and the lower blocking disc. The elastic terminal is mounted within the inner cylindrical body and adapted to be electrically connected with the mating terminal inserted into the inner cylindrical body through the outer through hole and the inner through hole.
