How can the UL  USB cable of the factory ensure the bending resistance performance?

Sinodec Industrial Co., ltd.  in china can provided micro USB,  USB3.0 type C, usb lightning cable, USB Type B, OTG USB3.0 cable, etc. which is Rohs &CE compliance for EU market, of course, we can also provide UL, California Prop 65 Compliance (US), Phthalate  free cord as per customers requested.All of the cable will have a very good bending resistance performance.

Many customers will consider bending resistance performance when choosing USB charger cord , such as the mouse cable, the  USB Type B printer cable, the POS cable, and so on.  How does the USB cable processing manufacturer meet the customer's bending resistance requirements?  Mainly through the following three aspects to achieve.

USB cable

1. Determine the conditions for the bending resistance test by asking the customer's use environment or the information provided by the customer.  Customize the wire of the corresponding specification to the wire supplier.  According to the test conditions, the wire supplier determines the material selection of the wire and the core wire, whether to add nylon wire and the selection of the position, etc. to achieve the customer's requirements; if the number of bending times reaches 20 million times or the use environment is bad,  It is necessary to consider the dragline;

2. USB cable manufacturer After the wire material manufacturer provides the wire sample, the swing test is performed.  The rocking test is to fix the wire on the fixture, hoist at a certain distance, and set the number of swings, the angle of the swing, and the frequency of the swing.  For example, 30CM, 90 degrees, 40 times per minute, hoisting 250G, the number of swings is ≥ 2000 times.

3. After the USB cable manufacturer has made the connection line, it will provide the sample to the customer, and the customer will perform another swing test verification, or actual measurement.  When the customer confirms that the sample meets the customer's requirements, it can be trial-produced in small quantities.  Then carry out mass production.

Therefore, whether it is a connection line in an industrial device or a consumer device connection line, the bending requirement can be ensured during the use of the customer.
