The invention discloses a shielding electric connector which is composed of a plug portion and a plug seat portion, wherein the plug portion comprises a plug shell, a plug base and a plug contact element. The plug seat portion comprises a plug seat shell and an inserting pin contact element. The plug portion is simultaneously provided with a shielding spring, rapid locking components and a tail cover. The shielding spring is installed on a corresponding position of the abutting end of the plug shell. The tail cover is installed on the tail end of the plug shell. The rapid locking components are fixed on two sides of the tail cover. The plug seat portion is simultaneously provided with an electric conduction rubber gasket. The electric conduction rubber gasket is installed on a corresponding position of the abutting end of the plug seat shell. The shielding electric connector is high in shielding effectiveness and capable of rapidly locking. At the same time, the shielding electric connector has the advantages of being compact in structure, small in size, light in weight, large in loading capacity, high in reliability, convenient to operate and capable of meeting multiple use requirements.
