Abstract
Abstract A contact retention mechanism for a smart card connector comprises a frame (12) and a number of contacts (3). The frame (12) forms a guiding recess (124) and a number of contact slots (125). A positioning slot (1250) is formed in each contact slot (125) and comprises a straight slot (1254) and a transverse positioning recess (1255). Each contact (3) is received in a corresponding contact slot (125) and comprises a contact body (30), a solder portion (31), a retention portion (33) and a contact portion (32). The solder portion (31) further comprises a pair of flanges (311) formed on opposite ends thereof for being received in the corresponding transverse positioning recess (1255) of the positioning slot (1250) thereby precisely maintaining the position and alignment of the contact (3).
