A SIM card connector includes a base, signal spring, a detection apparatus, and a controller. The detection apparatus includes a fixed contact and a detection spring. An action of a SIM card can be detected by means of separation or union between the fixed contact and the detection spring. A trigger part of the detection spring can press against a surface of the SIM card to move a movable end of the detection spring. A power supply of the signal spring can be cut off before the SIM card is separated from the signal spring, and the power supply of the signal spring can be switched on after the SIM card presses against the signal spring. |
