Abstract

A short circuit fault processing device and method are disclosed. The device includes a short circuit fault processing circuit. The circuit may include an input power supply, a drive power supply, a control module, a detection module and a fault processing module. The detection module sends signals to the control module when access of a terminal device to be charged is detected. The control modulewhen receiving the signals sent by the detection module establishes connection between a power supply input end of the terminal device and the drive power supply, and triggers passage signal detection by the detection module. The control module establishes connection between the power supply input end of the terminal device and the input power supply when the detection module detects that passagesignals are normal, or when the detection module detects that passage signals are abnormal, the control module sends a trigger signal to the fault processing module to trigger processing of a short circuit fault by the fault processing module. By adoption of the method and device, abnormal short circuit faults at a charge interface of the terminal device can be processed in time, thus prolongingthe service lifetime of the charge interface.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a short-circuit fault processing device and method. Background technique [0002] Currently, with the increasing popularity of terminal devices such as wearable devices or mobile phones, the terminal device has become one of the indispensable tools in the daily life of terminal device users. The higher the frequency of use of the terminal equipment, the higher the charging frequency of the terminal equipment. Currently, terminal devices such as wearable devices use more wired charging methods, that is, the terminal device needs to establish a wired connection with the charging device before it can be charged through the charging device. When the terminal device is charged with a wired connection through the charging device, the charging interface connected between the terminal device and the charging device is easily contaminated with liquid with electrolyte, such as water o...
