A waterproof electronic receptacle connector includes a plastic-core housing, an insulation housing, terminals, a waterproof ring gasket and a sealing material. The plastic-core housing includes a through hole. The insulation housing is configured in the through hole and includes a base and a tongue plate. The base includes an inner side plane facing toward the through hole and an outer side plane facing toward an outside of the through hole. The tongue plate is extended from the inner side plane. The terminals are passing through the base. Each terminal includes a contacting end extended from the tongue plate and a welding end connected to the contacting end and extruded from the outer side plane. The waterproof ring gasket is abutted between the base and an inner wall of the through hole. The sealing material is formed on the outer side plane to fill gaps between the terminal and the base.
