The embodiment of the invention discloses an interface device and a control method for the interface device, relates to the field of USB interfaces, and solves the problem of poor user experience when preventing corrosion of the USB Type-C interface. The specific solution is: the interface device includes a detection module, a processor, a controller and a connector, the detection module is used to obtain the voltage of the detection contact, and sends an indication message to the processor according to the voltage, and the indication information is used to indicate whether the connector is In contact with the electrolyte; the processor is configured to control the controller to output a low level to the first interface identification contact and the second interface identification contact when it is determined that the indication information indicates that the connector is in contact with the electrolyte. The embodiment of the present invention is used in the process of preventing corrosion of the USB interface.
Description
technical field [0001] Embodiments of the present invention relate to the field of Universal Serial Bus (Universal Serial Bus, USB) interfaces, and in particular, relate to an interface device and a method for controlling the interface device. Background technique [0002] At present, the USB Type-C interface has become the standard configuration of electronic devices such as mobile phones, computers, and televisions. The USB Type-C interface includes two CC contacts, which can output pulse power for connection identification. However, if the interface comes into contact with an electrolyte such as water, an electrolytic reaction will occur due to the pulse power supply, resulting in corrosion of the CC contacts. [0003] In order to prevent corrosion of the CC contacts of the USB Type-C interface, a plating layer can be added to the interface to isolate the contact between the CC contacts and the electrolyte. Alternatively, the connection identification function of the in...
