A plug connector includes a plug shell, a housing base and a plug contact. The housing base is combined with the plug shell and includes a main base and a tongue structure. The tongue structure extends from the main base and has a first face and a second face opposite to the first face. The plug contact includes a main body, a foot portion, a first end portion and a second end portion. The main body is mounted in the main base. The foot portion extends from the main body and stretches out of the main base. The first end portion is resiliently connected to the main body and protrudes out of the tongue structure via the first face. The second end portion corresponding to the first end portion is resiliently connected to the main body and protrudes out of the tongue structure via the second face.
