An electrical connector (100), includes an insulative housing (10), a plurality of conductive contacts (20) retained in the insulative housing, an insulative base (60) secured to the insulative housing, a subsidiary printed circuit board (30) connecting with the conductive contacts, a flexible printed circuit board (50) electrically connecting with the subsidiary printed circuit board, and a shielding shell (70) shielding peripherally around the insulative housing and the insulative base. The subsidiary printed circuit board is attached to the insulative base. A gap (609) is defined between a portion of the insulative base and an edge of the subsidiary printed circuit board. The flexible printed circuit board has a first strip portion (503) extending out of the insulative base, a second strip portion (501) connecting with the subsidiary printed circuit board, and a folded portion (505) between the two strip portions. The folded portion is received in the gap.
