With the development of The Times, mobile phones, smart watches, mobile power, digital cameras and other digital products have become our daily necessities. Some time ago, my friend bought a data cable for his mobile phone, but it could not be charged in less than a week. What's going on here? In fact, most likely, he bought a bad data line. And on the market a variety of brands of data cable, all kinds of, how should we choose a good data line?
01
Outside is material
The outer cover is the outermost and most intuitive part of the data line. The outer cover of the data cable on the market is generally divided into PVC and TPE materials.
PVC is a common plastic texture is stiff, cheap, but its service life is not as good as TPE.
TPE is a new material with high elasticity and strength of rubber as well as the characteristics of plastic injection molding. The data line made by TPE is durable, smooth, safe and non-toxic, and will not cause any irritation to human skin.
Nowadays, most of the international first-line brands choose TPE as the data line outside the material, in the selection of data line should try to choose the wire diameter thick and wire surface does not reflect the data line, the thicker the wire, the higher the tensile strength, the copper core has a good protection; The less reflective the surface of the wire, the higher the content of TPE in the wire. This data cable has good elasticity, anti-aging and is not easy to break. Therefore, good data line is more common wire from the quality and line diameter will be slightly larger, feel smooth and thick.
02
core of cable
The inferior data cable is generally used in copper clad steel, copper clad iron, copper clad copper, steel and other relatively inferior material core.
First, we can use ferromagnetism to distinguish. The magnet close to the line of the data line, can feel the magnetic force, and even can be the data line adsorption, the data cable is a relatively inferior core. Just take a look at the picture below.
Second, use the combustion method to distinguish.
High quality wire core is generally tinned copper and pure copper. Tinned COPPER CORES AND PURE COPPER CORES BURN FOR A PERIOD OF TIME, slowly burning backward, with less burning material falling off, as shown IN THE picture below.
After the combustion of the inferior wire core with more impurities, some substances are scattered around, just like fairy flowers.
This kind of core charging will be hot, and short life, less than a month can not charge.
Enamelled steel, enamelled iron core, some companies in order to pretend to be copper wire, steel wire, iron wire dipped yellow paint, the surface looks like pure copper copper wire, but the paint is flammable, lit can continue to burn or even have an open flame flame.
This kind of wire core charging will also be hot, and after a period of time, the more slowly charging.
