An electrical connector (100) assembled to a printed circuit board (5) for connecting with a mating connector, includes a longitudinal insulative housing (1) and a plurality of contacts (2, 3) received in the housing. Each of the contacts (2, 3) defines a retaining section (20, 30), a contacting portion (21) extending forwards from the retaining section for contacting with the mating connector and a compressing portion (220, 320) extending rearwards from the retaining section for connecting to the printed circuit board. The compressing portions are arranged in two rows, and the compressing portions nip and elastic compress against the printed circuit board instead of being soldered thereto to connect the electrical connector to the printed circuit board steadily.
