Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0021] see figure 1 , a preferred embodiment of the present invention provides a test method for USB data line samples. The testing method of described USB data line sample comprises steps:

[0022] Step S101, performing appearance and size tests on the USB data cable samples.

[0023] This step is specifically: at room temperature, in a brightly lit environment, visually check whether the surface of the test sample is dirty, whether the logo is correct, whether the wire body and plug are damaged, whether the metal edge of the plug is covered with peaks, and whether the metal parts are Corrosion, whether the PIN pin inside the plug is deformed, warped, oxidized, etc. Afterwards, use a circle ruler to measure whether the length of the data line meets the parameters of the te...

Abstract

The invention provides a test method for a USB (universal serial bus) data wire. The test method is used for carrying out reliability detection on the USB data wire and comprises the following steps that a USB data wire sample is subjected to appearance and dimension test; in addition, after the appearance and dimension test, the USB data wire sample is sequentially subjected to matching performance test, insulation voltage-withstand test, bending fatigue test, connecting force intensity test, plugging and unplugging fatigue test and full-load aging test. The test method for the USB data wire provided by the invention has the advantages that the long-time use process of the USB data wire can be simulated, and the reliability of the USB data wire can be effectively detected.

Description

technical field [0001] The invention relates to a testing method for a USB data line. Background technique [0002] Universal Serial Bus (USB) is a commonly used PC interface and the most widely used external bus standard in the PC field, used to standardize the connection and communication between computers and external devices. The USB interface supports the plug-and-play and hot-swappable functions of the device, which can transmit data conveniently, quickly and stably, supports all types of computers, and supports mice, keyboards, printers, scanners, cameras, flash drives, MP3 machines, mobile phones, digital Electronic products such as cameras, mobile hard drives, and USB network cards are widely used in daily life. As a bridge between the computer and the device, the USB data cable is often bent, wound, pulled, plugged and unplugged during use. The parameters and quality of the data cable are particularly important. The USB data cable is an effective guarantee for da...
