There are many kinds of mobile phone data lines in the market, and the quality is also uneven. How to choose a quality USB power charging and data sync cable?
First, the material of wire:
1. Wire material: The core strength of the pure copper core is small, which can improve the charging efficiency. Therefore, we must choose the data lead made of pure copper core material.
2. Selection of shielding layer: Aluminum foila and metal braided mesh shielding are needed outside the inner core to resist electromagnetic interference and the transmission is faster and more stable. However, since the core of the data line cannot be directly seen by the naked eye, when purchasing, you can try to select a data line with a large diameter.
3, Wire sleeve: good wire sleeve can reduce the internal copper core of the data line is affected by external tension and damage, so check the cable itself is tensile and strong.
Second, the material of USB connectors:
The most easily broken part of the USB cable is the connectors, a quality USB cable have a ver strong connectors, the material being used will be very important, Usually, it is made of aluminum alloy material, which can effectively avoid the oxidation and rust of metal.
Third, the processing technology:
The USB data cable interface and the wire which are pressed by the plastic mixed rubber are pressed together, and the tensile strength is good, which is beneficial to prolonging the service life of the data line, and also has a certain protection effect on the control chip in the data line interface. The mobile phone data cable produced by Sinodec Industrial Co., ltd. in china uses high-quality tinned copper core wire for the selection of wire. The output rate is up to >97% and the speed increased 30% . The high-end aluminum alloy is used in the interface part to effectively avoid the interface being affected by oxidation and rust.
