USB connecting port assembly, detecting method thereof and man-machine interaction equipment

Abstract

The invention discloses a USB connecting port assembly. The USB connecting port assembly comprises a female connecting port which is matched with a male connecting port of an external connector, wherein the female connecting port comprises a master control chip, a GND pin and an ID pin; the GND pin and the ID pin are both electrically connected with the master control chip; the GND pin and the IDpin are arranged at intervals; the female connecting port further comprises an additional detecting pin which is connected with the master control chip; the additional detecting pin is positioned at the position which is close to the edge of the female connecting port; when inserted in the female connecting port, the male connecting port is in contact with the additional detecting pin; and when the master control chip receives the signal shows that the additional detecting pin is in contact with the male connecting port, the GND pin and the ID pin are controlled to energized. The invention further provides a method for detecting the USB connecting port assembly and man-machine interaction equipment. By the technical scheme, short-circuiting and electrolytic corrosion of the USB connectingport are avoided.

Description

technical field [0001] The invention relates to the field of universal serial bus devices, in particular to a USB connection port component, a detection method thereof, and a human-computer interaction device. Background technique [0002] Applied to mobile communication and human-computer interaction devices with USB connection ports such as mobile phones, PADs, and vehicle terminals. Usually, the above-mentioned USB connection ports have GND, ID, D+, D-, and VBUS pins, and the ID pin is used for Detect whether there is an external device inserted, the VBUS pin is used to receive the signal from the ID pin that the external device is inserted, and then output high voltage and high current to perform operations such as charging or data transmission for the inserted external device; and the ID pin is for To be able to realize the detection function, it is necessary to go out for a long time and be in a standby state, and the ID pin is adjacent to the GND pin; in actual use, i...

If the electrolytic corrosion is severe, the USB connection port cannot be charged or cannot transmit data.
