An electrical connector is provided, including a main body, first terminals installed at a seat of the main body, second terminals embedded in the seat, and a housing. The housing has a bottom wall, two side walls, and a top wall, and defines an accommodating space having a first opening and a second opening. A plurality of first spring plates are disposed on the top wall and bottom wall. A second spring plate is disposed near the second opening of the top wall. Third spring plates are disposed near the second opening of the bottom wall. When a connector plug is plugged into the electrically connector, the first, second and third spring plates make contact with an iron housing of the connector plug to increase the contact area between the connector plug and the electrical connector, and reduce electromagnetic interference to peripheral devices.
