US Patent 7175480 Connector and a terminal fitting

A terminal fitting (20) has close-contact portions (24) that frictionally engage inner walls (11a) of a press-in hole (11), biting projections (25) behind the close-contact portions (24) for biting in the inner walls (11a) of the press-in hole (11) and recesses (26) behind the biting projections (25). The close-contact portions (24) are held in sliding contact with the inner walls (11a) at an initial stage of the pressing operation. Thus, a resistance is smaller as compared to a case where projections are moved while biting in the inner walls (11a).
