Abstract
The utility model discloses a SIM card connector which can hold well the conductive terminal and the conductive terminal, including an insulating body and a plurality of conductive terminals. The insulating body have accepting slots provided with an accepting cavity at both laterals. The conductive terminal has a first connecting part arranged in the accepting slot and one end of the first connecting part extends to form a welding part. The other end of the first connecting part bends and extends upwards to form a folding part. The terminal of the folding part extends with a second connecting part in parallel with the first connecting part. The terminal of the second connecting part protrudes and extends upwards to form a touching part. The two sides of the first connecting part extend outwards and upwards to form a fixing part inserted in the accepting cavity. One lateral of the fixing part extends and protrudes outwards a clamping-holding block clamping the accepting cavity. Therefore, when the insulating body is softened in the making process of SMT, the clamping-holding block intervenes with the inner wall of the accepting cavity to prevent the welding part of the electric-guide terminal being bounced out of the insulating body to enable the SIM card connector to be welded on the circuit board of the mobile phone firmly.
