Receptacle connector integrating with different interfaces

An electrical assembly comprising:

• an insulative housing;
• a metallic shell enclosing said housing, said shell including a pair of opposite horizontal side walls to thereof define and divide a large interface and a small interface respectively in a vertical direction to receive a large tongue plate and a small tongue plate which respectively extends from the housing, wherein said large interface is larger than the small interface in a transverse direction perpendicular to said vertical direction;
• said large interface and said small interface intimately neighboring with each other in said vertical direction via sharing a same boundary while being configured to be respectively coupled to complementary mating interfaces of corresponding first and second plugs without interference in the vertical direction when said complementary mating interfaces of both said first plug and said second plug are simultaneously inserted in to the shell under condition that outer covers of both said first plug and said second plug are respectively coplanar with the corresponding complementary mating interfaces thereof without interference in the vertical direction.
