US Patent 10003161 Electrical connector

An electrical connector includes a metallic shell structure having a port, an insulation housing disposed in the metallic shell structure, a shielding plate disposed inside the insulation housing, and two rows of conductive terminal sets disposed on the insulation housing with each on two opposing sides of the shielding plate. A conductive contact portion is formed around the port by the metallic shell structure. Therefore, as the electrical connector is assembled with an external device, the conductive contact portion can be in contact with the external device. Hence, a grounding effect is achieved, and an electromagnetic compatibility is improved.
