  • Patent number: 10027360
    Abstract: 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. 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, 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.

  • Patent number: 9985674
    Abstract: 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.
