Open state；When the time span that SIM card support is contacted with SIM card holder shrapnel is in preset time, SIM card holder shrapnel is by ground connection shape
State become with SIM card support contact condition, when pulse-generating circuit generate high level pulse signal, power switch disconnect, control core
Piece is in off state；The time span that SIM card support is contacted with SIM card holder shrapnel is more than high level pulse signal after preset time
Become low level from high level, power switch is closed, and control chip becomes open state, so far passes through the plug pair of SIM card support
It controls chip and completes primary reset.
It should be noted that pulse-generating circuit can be multivibrator circuit or Schmitt trigger pulse circuit,
The utility model is not particularly limited pulse-generating circuit.
It should be noted that preset time can be 0.1s, 0.2s, 0.3s, those skilled in the art can be according to reality
Situation selects preset time, and the utility model is not specifically limited preset time.
Another kind is controlled as follows by way of power switch is closed or disconnects the pulse signal that pulse-generating circuit exports：
Setting low level pulse signal makes control chip close.
When SIM card support is not inserted into SIM card holder, control chip is open state；SIM card support is contacted with SIM card holder shrapnel
In preset time, SIM card holder shrapnel is become generating with SIM card support contact condition, at this time pulse time span from ground state
Circuit generates a low level pulse signal, and low level pulse information controls power switch and disconnects, and then control chip becomes closing
Closed state；After SIM card support and SIM card holder shrapnel time of contact length are more than preset time, low level pulse signal is from low level
Become high level, power switch is closed, and control chip is open state.
In the utility model embodiment, according to the SIM card support of mobile terminal and the structure design of SIM card holder, to realize
Reset is reopened to MCU.Since pulse-generating circuit is connected on the access that SIM card holder shrapnel is connect with power switch
On, then when SIM card support is inserted into SIM card holder, by controlling the pulse signal of pulse-generating circuit, and control closing for power switch
It closes, to control the reset of chip, and then can realize when mobile terminal crashes, adjusted by the extraction of SIM card support, insertion
The state of control control chip promotes the use of user to solve the problems, such as to cannot be started up in the case where mobile terminal crashes
Experience.
