Patent attributes
A receptacle connector is arranged on an interface of an electronic device for mating with a corresponding plug connector. An anti-incorrect-insertion block is arranged on and protruded from a mating portion of the plug connector. The receptacle connector comprises an insulating housing, conductive terminals assembled in the housing and a first shielding shell for covering on the outside of the insulating housing. A soldering portion welded to a circuit board is arranged on the lower edge of the first shielding shell. The receptacle connector is further provided with a second shielding shell for shielding the electromagnetic signals from the fool-proof opening of the interface. A receptacle connector of the invention shields the fool-proof opening by adding the second shielding shell, thereby preventing the electromagnetic leakage, improving the anti-electromagnetic interference capability of the connector and ensuring an electrical connection of the connector.
