An electrical connector (100) includes an insulative housing (1) defining a number of passageways (121) for receiving corresponding contacts (2), and a metal shield (3) enclosing the insulative housing (1). The metal shield has a top face (31), a bottom face (32) and a pair of side faces (33). The bottom face includes a pair of first board mounting legs (325) downwardly and a slot (326) between the first board mounting legs (325). The first board mounting legs (325) are disposed in communication of the slot (326) and mounted on a printed circuit board (4). The length of the slot (326) is equal to the total length of the first board mounting legs (325). With the addition of the first board mounting legs (325), the connector (100) can be more stably mounted on the printed circuit board.
