Abstract

The invention, which relates to the technical field of USB data line testing, discloses a USB data line detecting system and device so that a problem of low detection sensitivity of the existing USB data line testing device can be solved. After two ends of a data line are respectively inserted into a first adapter and a second adapter, a control signal is sent to a control circuit through a communication module if a tester detects that the performance of the data line is good, so that a power input circuit and a power output circuit are connected. Because of the high current sensitivity by anindication light, the indication light emits a non-bright or flickering signal if a short-circuit, open-circuit or poor connection problem occurs in the data line. The detection sensitivity is high.

Description

technical field [0001] The invention relates to the technical field of USB data line testing, more specifically, it relates to a USB data line testing system and device. Background technique [0002] The USB data cable is used for the connection and communication between the computer and the external device, and can also be used for the charging of the mobile phone and the connection with the outside. It includes five lines inside, which are power line (VCHG), ground line (GND), positive data line (USB_D+), negative data line (USB_D-) and signal shielding line. After the USB data cable is produced, in order to ensure its charging performance and data transmission performance, it is usually tested for short circuit and open circuit. [0003] The Chinese patent with the existing authorized notification number CN205404693U discloses a USB data line swing limit test device, which includes a test device and a base. The front side of the test device is provided with a test port c...
