WIPO Patent Application WO/2019/192212
Kind Code:
A1
Abstract:
A data cable for a mobile phone. The data cable comprises a body, the body being internally provided with a first connection terminal (1) connected to an external device, a second connection terminal (2) connected to a mobile phone and a connecting line (3) for connecting the first connection terminal (1) and the second connection terminal (2), wherein the connecting line (3) comprises a twin-core data communication line (31) and a twin-core voltage line (32). The data cable further comprises a display screen (4) disposed outside of the body, and a DSP chip (5), a voltage detection circuit (6) and a current detection circuit (7) disposed inside the body, wherein a first end of the DSP chip (5) is connected to a first end of the voltage detection circuit (6), a second end thereof is connected to a first end of the current detection circuit (7), and a third end thereof is connected to the display screen (4); a second end of the voltage detection circuit (6) is connected to one core in the twin-core voltage line (32), and a third end thereof is grounded; and a second end and a third end of the current detection circuit (7) are connected in series on the other core in the twin-core voltage line (32), thus realizing the connection between the first connection terminal (1) and the second connection terminal (2). The data cable can monitor a voltage and/or a current flowing through the data cable in real time when a mobile phone is charged and discover and eliminate hidden dangers in a timely manner, thereby reducing the probability of damage occurring during mobile phone charging.
