摘要:
A SIM card connector includes a base, signal spring, a detection apparatus, and a controller. The detection apparatus is disposed at a bearer panel of the base, and 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. Compared with the signal spring, the trigger part is closer to the bearer panel. During a process of inserting or removing the SIM card, the SIM card can move the movable end to trigger a change in separation and union between the detection spring and the fixed contact. In addition, by using the controller, 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. 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.

An RFID card includes a smartcard controller that receives power from a host device. The RFID card also includes a small inductive device capable of inductive coupling with an RFID reader. The small inductive device is small enough to fit in the form factor of a memory card or SIM card. Enhancement circuits enhance the usable read and write distance of the RFID card.
摘要:
An SIM card connector and a mobile terminal are disclosed. The SIM card connector comprises a card holder as well as a power supply terminal, a first terminal and a second terminal disposed within the card holder. When the SIM card is plugged, the power supply terminal connects with a power supply contact of the SIM card earlier than the first terminal, and the first terminal connects with the power supply contact earlier than the second terminal. The mobile terminal comprises an interruption detection module, a power supply management module and an SIM card connector. The power supply management module is configured to, when the SIM card is plugged in a powered-on state of the mobile terminal, supply power to the power supply terminal; the interruption detection module is configured to, if it is detected that neither of the levels at the first terminal and the second terminal is a predetermined level, transmit a first control signal to the power supply management module, and otherwise, transmit a second control signal to the power supply management module; and the power supply management module is further configured to stop supplying power to the power supply terminal when it is determined that the signal received changes from the second control signal into the first control signal. With the present disclosure, short-circuit of the SIM card when the SIM card is removed in a powered-on state of the mobile terminal can be prevented.
摘要:
According to one embodiment of the present disclosure, an electronic device may comprise: a housing comprising a first through hole, which is formed so as to pass through a lateral surface, and a second through hole which is disposed adjacent to the first through hole and formed so as to pass through the lateral surface; a protruding portion disposed so as to at least partially face the second through hole inside the housing; a socket disposed inside the housing so as to be aligned with the first through hole; a push bar disposed on one side of the socket so as to be linearly reciprocatable, and at least partially aligned with the second through hole; and a waterproof pin accommodated in the second through hole to seal the second through hole, and formed so as to move the push bar by linearly reciprocating inside the second through hole by an external force. In one example, when the waterproof pin reaches a designated location in the second through hole, a first area of one end face of the waterproof pin comes into contact with the push bar, and a second area, different from the first area, of the one end face of the waterproof pin comes into contact with the protruding portion. Various other embodiments are possible.
