用于USB TYPE-C线材的智能测试电路及其测试方法Intelligent test circuit and test method for USB TYPE-C wire

技术领域 technical field

本发明涉及USBType-C线材技术领域，特别是涉及一种用于USBTYPE-C线材的智能测试电路及其测试方法。 The invention relates to the technical field of USB Type-C wires, in particular to an intelligent test circuit for USB Type-C wires and a testing method thereof.

背景技术 Background technique

USBType-C主要有三种传输功能，分别是USB数据、供电/充电、DisplayPort视频。总结说来，USBType-C至少具有以下优点：1、最大数据传输速度达到10Gbit/秒，也是USB3.1的标准；2、USBType-C插座端的尺寸约为8.3mm×2.5mm；3、支持从正反两面均可插入的“正反插”功能，可承受1万次反复插拔。基于上述优点，在不远的将来，手机、平板、笔记本、台式机等电子通讯设备的通讯接口均会标配USBType-C，USBType-C线材的市场需求巨大。 USB Type-C mainly has three transmission functions, namely USB data, power supply/charging, and DisplayPort video. In summary, USB Type-C has at least the following advantages: 1. The maximum data transmission speed reaches 10Gbit/s, which is also the standard of USB3.1; 2. The size of the USB Type-C socket end is about 8.3mm×2.5mm; 3. Support from The "front and back insertion" function, which can be inserted on both sides, can withstand 10,000 times of repeated plugging and unplugging. Based on the above advantages, in the near future, the communication interfaces of electronic communication devices such as mobile phones, tablets, notebooks, and desktop computers will all be equipped with USB Type-C as standard, and the market demand for USB Type-C cables is huge.

USBType-C线材的插头具有如图2所示引脚；USBType-C插座端具有如图3所示引脚。 The plug of the USB Type-C cable has the pins shown in Figure 2; the USB Type-C socket end has the pins shown in Figure 3.

USBType-C线材出厂前要测试USBType-C线材的第一端和第二端正反插时的电气连接是否正常，传统的做法需测试四次：即，第一端进行正反插测试两次，对调第二端后再进行正反测试两次，导致测试次数较多、用时较长，不利于USBType-C线材的批量生产。 Before the USB Type-C cable leaves the factory, it is necessary to test whether the electrical connection between the first end and the second end of the USB Type-C cable is normal. The traditional method needs to be tested four times: that is, the first end is tested twice for positive and negative insertion. Swap the second end and then perform the front and back tests twice, resulting in more tests and longer time, which is not conducive to the mass production of USB Type-C cables.
