An audio jack connector (100) includes an insulative housing (1) and a number of contacts (2) retained in the insulative housing. The insulative housing defines a receiving channel (14) and a number of terminal passageways (121). The contacts include a grounding contact (25, 25′) having a retaining portion (256; 256′) retained in the corresponding terminal passageway, a contacting portion (257; 257′) extending from the retaining portion into the receiving channel, a soldering portion (258; 258′) coplanar with a mounting face of the insulative housing, and a connecting portion (259; 259′) vertically connected between the retaining portion and the soldering portion. The connecting portion forms an auxiliary portion (2591; 2591′). Both the auxiliary portion and the retaining portion engage with the insulative housing.
