A SIM card connector includes a base, signal spring, a detection apparatus, and a controller. The detection apparatus is configured to cooperate with one side of a SIM card, and includes a fixed contact and a detection spring, where an action of the SIM card can be detected by separation or union between the fixed contact and the detection spring. A trigger part of the detection spring can press against the end of the SIM card to move a second end of the detection spring, and compared with a pressing part, the trigger part is closer to a bearer panel. In a process of removing or inserting the SIM card, the SIM card can move the second end of the detection spring, and trigger a change in separation and union between the detection spring and the fixed contact; the controller can disconnect a power supply of the signal spring before the SIM card is separated from the signal spring, and can switch on the power supply of the signal spring after the SIM card presses against the signal spring; the controller switches on or off the power supply in a timely manner, which effectively prevents the SIM card from being burned out by a momentary electric arc generated between the SIM card and the signal spring when the SIM card is being inserted or removed. The present invention further provides a mobile terminal having the foregoing SIM card connector. |
