Electrical connector having elastic card-ejecting member

An electrical connector to be disposed on a main board, and to be connected to and engaged with a circuit board, the electrical connector comprising:

• a plastic base, which is fixed to the main board and formed with a connection slot, wherein the connection slot has an opening, and one end of the circuit board may be inserted into and connected to the opening;
• a plurality of terminals disposed on the plastic base, wherein each of the terminals has a projecting connection point disposed on the connection slot;
• a board engaging structure having at least one engaging portion, which can engage with the circuit board when the circuit board is inserted into the connection slot for positioning;
• and
• at least one elastic card-ejecting member, which enters a forced state when the one end of the circuit board is inserted into the connection slot by a stroke, and pushes the circuit board out by another stroke so that the circuit board is engaged with the engaging portion when the elastic card-ejecting member bounces, wherein the board engaging structure comprises two lateral arms, which are disposed on two sides of the plastic base and extend toward the opening of the connection slot, and an engaging portion is disposed near an outer end of each of the lateral arms.
