Embodiment Construction

[0042] A USB3.1 TYPE-C type cable automatic testing method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] Such as figure 1 As shown, a USB3.1 TYPE-C cable automatic testing method, including steps:

[0044] S1: install a measurement tool at the two ports of the USB cable respectively, and perform initialization processing;

[0045] S2: Let i=1;

[0046] S3: sending a high / low level to the i-th IO port in the USB cable;

[0047] S4: Detect whether the IO line corresponding to the IO port is short-circuited with the connected IO line and store the test result in a register;

[0048] S5: Detect whether the IO line is disconnected and store the test result in the register;

[0049] S6: Determine whether i is equal to the total number of IO lines in the USB cable, if not, execute S7; otherwise, end;

[0050] S7: i=1+1, return to step S3.

[0051] Specifically, the USB cable includes i...

Abstract

The invention provides a USB 3.1 C type cable automatic test method. The method comprises the steps of S1, respectively arranging a measurement tool at each of the two ports of a USB cable, and conducting the initial treatment; S2, setting i to be 1; S3, sending a high / low level to the i IO port of the USB cable; S4, detecting whether an IO line corresponding to the above IO port and an adjacent IO line are short-circuited or not and then storing the detecting result in a register corresponding to the IO port; S5, detecting whether the IO line is disconnected and then storing the detecting result in the register; S6, judging whether i is equal to the total number of IO lines in the USB cable; if not, executing the step S7; otherwise, ending the process; S7, i=i+1 and returning to execute the step S3, wherein the USB cable is composed of i IO lines and i is a positive integer greater than 0. In this way, the error of the manual operation is reduced, and both the testing efficiency and the first pass yield are increased. Meanwhile, the measurement tools are controlled by a personnel computer (PC) and test results are uploaded to the PC. As a result, the quality track of products is facilitated.

Description

technical field [0001] The invention relates to the technical field of power communication, in particular to an automatic test method for USB3.1 TYPE-C cables. Background technique [0002] USB3.1 TYPE-C is a relatively advanced high-speed communication cable. In the current production and processing process, the processing of the cable is mainly tested manually, which is inefficient and has a defect rate of more than 10%. At the same time, because the USB3.1 TYPE-C cable supports two-way power supply, there is a power control chip in the cable, which requires professional testing equipment to complete the test. Due to the impact of the defective rate, it may cause USB3.1 TYPE-C testing Damage to equipment and USB3.1 TYPE-C equipment. [0003] During the production and processing of the USB3.1 TYPE-C cable, there may be short circuits or tin connections due to operational errors during the welding process. In this case, if it is used directly, it will cause damage to the U...
