An electrical connector comprises a dielectric body, a plurality of terminals, and a metal shell. The dielectric body includes a base and a tongue. The tongue extends forward from the base and supports the plurality of terminals. The metal shell is integrally formed around the dielectric body, and can be formed by bending a metal plate, and includes a top wall, a bottom wall opposite to the top wall, a first side wall, and a second side wall, the four walls defining a rectangular opening. The first side wall includes a lower wall portion and an upper wall portion, both of which are joined at a seam on the first side wall. The lower wall portion has a lower solder leg and the upper wall portion has an upper solder leg and the lower and upper solder legs can be soldered to the circuit board.
