In the journey of t-type double-ended braided data cable from production line to market, a series of rigorous durability tests are the key to ensure its excellent quality.
The plug-in test is the first to bear the brunt, simulating the situation of frequent daily connection of devices. The robotic arm accurately simulates the plug-in and pull-out actions of human hands. According to industry standards, T-type data cables need to undergo thousands of plug-in and pull-out cycles, such as the common USB interface end must withstand at least 5,000 times. The angle and depth of each plug-in and pull-out are strictly controlled, and the degree of interface wear and contact stability are monitored to ensure that after multiple plug-ins and pull-outs, the metal contacts are still tightly fitted, and the signal transmission and charging functions are not attenuated, eliminating data interruption or slow charging caused by poor contact.
The bending test simulates the fate of the data cable being repeatedly bent in a backpack or pocket. Special equipment fixes the two ends of the data cable and repeatedly bends it according to a certain curvature radius, and the T-type branch is the focus of attention. High-quality data cables must be able to withstand tens of thousands of bends. For example, near the mobile phone connector, which is frequently bent every day, the number of bends can reach more than 10,000 times. The test monitors whether the insulation layer of the internal wire is damaged or whether the wire is broken. Once a slight crack is found, the production link will be traced back to find defects in time to prevent sudden circuit failures during use.
The tensile test is like a tug-of-war competition to test the toughness of the data cable. Applying gradually increasing tension in different directions to simulate the scene of accidental pulling. The upper limit of the tension depends on the thickness of the wire diameter and the strength of the material. The thick wire can withstand up to tens of Newtons of tension. Monitor whether the outer braided layer is loose and the displacement of the internal core wire to ensure that even if there is a sudden pull, such as being tripped by the corner of the table, it will only recover quickly after elastic deformation, and the data transmission and power supply links will not move.
The temperature cycle test allows the data cable to be "tempered" in both ice and fire. From the low temperature of tens of degrees below zero Celsius to the high temperature of 60 to 70 degrees Celsius, it simulates the extreme cold outdoors and the heating of the equipment. After dozens of hot and cold cycles, observe whether the outer skin material is brittle or softened, and whether the sealant at the interface fails to cause water vapor to corrode the line, ensuring that the data cable is universal and has constant performance in all seasons.
In addition, there is a salt spray test to simulate the highly corrosive seaside or industrial pollution area environment to test the anti-corrosion ability of metal parts; a wear test to use rough objects to simulate friction with the desktop and debris in the bag to test the wear resistance of the braided outer skin, so as to ensure that the data cable has a intact appearance and the same performance for a long time, and become a reliable and durable connection link in the hands of users.
