The utility model discloses an electrical connector comprising an insulating body, a plurality of first conductors, a plurality of second conductors, a plurality of liquid conductors and a plurality of insulating elastic bodies. The insulating body is provided with a plurality of accommodating grooves. As accommodating cavities for accommodating the liquid conductors are jointly formed by the first conductors and the corresponding accommodating grooves instead of being formed only by concavely arranging the first conductors, the sizes of the first conductors can be reduced. The insulating elastic bodies are fixedly arranged on the second conductors and seal the accommodating grooves, which can prevent the liquid conductors from leakage and oxidation. The second conductors have second extension parts extending into the accommodating cavities. The insulating elastic bodies are integrally molded through electrical connection between the liquid conductors and the first conductors, which can simplify the process and assembly.
