Abstract: An electrical connector includes an insulating body having an accommodating slot vertically running therethrough, a terminal and an elastic body. The terminal has a base correspondingly accommodated in the accommodating slot. An elastic arm extends upward from the base. A contact portion extends from the elastic arm to be electrically connected to a first mating member. A bottom end of the terminal is used to be electrically connected to a second mating member. The elastic body is provided on the elastic arm. The elastic body is only in contact with the elastic arm. The elastic body includes an elastic insulating member and dielectric particles mixed with the elastic insulating member. A dielectric coefficient of the dielectric particles is greater than a dielectric coefficient of the electric insulating member.
