Carry out collocation channel detection).In this way, compared with prior art, since the second end at least one elastic slice connects at least one
It when ground pin contacts, can be controlled by triggering interrupt signal to connectivity port output pulse signal, and no longer be routinely
To connectivity port output pulse signal, thus can reduce connectivity port occur electrochemical corrosion a possibility that, so as to
The accuracy of the data on detection connectivity port is improved to a certain extent.In addition, since terminal device is to interrupt letter by triggering
Number control to connectivity port output pulse signal, and be no longer routinely to connectivity port output pulse signal, therefore can be with
Reduce the power consumption of terminal device.
