In one embodiment, instantaneous voltage when being contacted according to the power pins of the SD card and the conductive unit is examined
Survey the plug state of the SD card, comprising:
When the instantaneous voltage is lower than preset threshold, the SD card is in extraction state.
During pulling out SD card extraction, the conductive unit on Kato can be contacted with the power pins, can make SD
The power pins of card are connected with the grounding pin of SD card, and then short circuit.Transient current when short-circuit is big, and instantaneous voltage is small.
That is, when the instantaneous voltage when conductive unit and power pins contact is lower than preset threshold, it can be determined that obtain
The power pins of SD card are connected and short-circuit with the grounding pin of SD card, at this point, SD card is in extraction state.
When SD card is in extraction state, the usual triggered time is 200 microseconds (us), can quickly and effectively turn off SD card
Power supply.
Due to triggering the low pressure difference linear voltage regulator in the power management module when SD card is in extraction state
Overcurrent protection disconnects the power supply of SD card.During being inserted into SD card, can also conductive unit be made to contact with power pins, still

Exempt from the generation for causing SIM card to burn card phenomenon because of the failure of conductive unit, needs to detect the validity of conductive unit.
Further, the validity for detecting conductive unit, specifically includes: the power pins and conductive unit for detecting SD card connect
Transient current when touching；When transient current is less than pre-set current value, then determine that conductive unit fails.When conductive unit and power supply draw
When foot contacts, the power pins of SD card can be made to be connected with the grounding pin of SD card, and then short circuit, and transient current when short circuit
It can be more than pre-set current value.When transient current when the power pins of SD card and conductive unit contact is less than pre-set current value,
Then determine that conductive unit fails.
Step 506: when conductive unit failure, detecting the variation shape of the level value of the plug state detection pin
State.
When conductive unit failure, the detection circuit in terminal can detecte the level of the plug state detection pin of SD card
The variable condition of value.Wherein, variable condition can become high level from low level, can also become low level with high level.When slotting
The level value for pulling out state-detection pin becomes high level from low level, then it represents that SD card is in insert state at this time.
Step 508: when the level value of plug state detection pin becomes low level from high level, controlling the electricity
Source control module disconnects the power supply of the SD card.
When the level value of plug state detection pin becomes high level from low level, then it represents that SD card is in insertion at this time
State.And when the level value of plug state detection pin becomes low level from high level, then it represents that SD card, which is in, at this time extracts
State controls the power supply that the power management module disconnects the SD card.
In the present embodiment, even conductive unit breaks down, by detecting, judging that SD card plug state detects pin
The variation of level value, and then can control the power supply that power management module disconnects SD card in time when SD card is extracted, guarantee SIM
Card is not burned.
In one embodiment, prevent SIM card from burning the method for card, further includes:
Step 602: detecting the validity of the conductive unit.
Further, the validity for detecting conductive unit, specifically includes: the power pins and conductive unit for detecting SD card connect
Transient current when touching；When transient current is less than pre-set current value, then determine that conductive unit fails.When conductive unit and power supply draw
When foot contacts, the power pins of SD card can be made to be connected with the grounding pin of SD card, and then short circuit, and transient current when short circuit
It can be more than pre-set current value.When transient current when the power pins of SD card and conductive unit contact is less than pre-set current value,
Then determine that conductive unit fails.
Step 604: when conductive unit failure, judging whether the plug state detection pin for detecting the SD card
The signal of output.
In the case where conductive unit failure, in order to avoid SIM card burns the generation of card phenomenon, double insurance machine can be set
System.Can according to the demand of user, the meaning of the plug state pin of customized setting SD card.When terminal is able to detect that SD card
Plug state pin real-time output signal when, then it is assumed that the SD card is in insert state, when terminal fails to detect SD card
Plug state pin real-time output signal when, then it is assumed that the SD card is in plug state.
When the plug state that the SD card is not detected detects the signal of pin output, 606 are thened follow the steps: control electricity
Source control module disconnects the power supply of the SD card.
In the present embodiment, even conductive unit breaks down, and detects that SD card plug state detects by judging whether
The signal of pin output, and then can control the power supply that power management module disconnects SD card in time when SD card is extracted, guarantee
SIM card is not burned.
