Many mobile phone users are usually based on the phone's interface type to select the data lines, some friends will also take into account the brand and price. Obviously look similar data why the product line so the price difference is too large? In addition to the brand value, the internal structure of the data lines, materials, workmanship, with or without certification (mainly apples lighting line) and other aspects of the data lines are an important factor affecting prices. Of course, these are also related to experience the effect of the product. This article we mainly introduce the data line cable itself is generally configured.
◎ core
Core data lines for data transmission and an important carrier of charge, their number and weight differ. Currently we market data line conductor wire core have two, four, more than six kinds of specifications. Four core products more common, it is usually red (orange), black (blue), white, green, four colors, namely 5V power supply, GND bottom line, D- data, D + data. Red (orange), black (blue) is mainly used for charging two cores, white, green core is mainly used for data transmission. Under normal circumstances, the first two little thicker than the latter two. Core copper wire and a conductor is composed of an outer, often using copper as a bare copper or tinned copper wire core material outside is often pvc or HD-PE. Depending on the application and requirements, the number of copper wire and conductor thickness design are different.
◎ shield
In order to protect the life and stability of the data signal transmission line, part of the data line will use the shield wire core wrapped up. You can add an additional layer of metal layer of aluminum foil or braid shield to be both increased, multilayer shielding technology can better protect data line results, but the cost is relatively higher. Naturally, some of the data cable is not shielding layer, but does not increase the shielding of data lines prolonged use may appear short circuit and so on.
◎ Jacket
Data lines are used more for the TPE and PVC material, they have good resistance to abrasion and dirt force, TPE PVC relative softness better, more environmentally friendly. The body shape of the line can create conventional round wire, flat wire and can be extruded triangle, the outer is also a variety of colors: light gray, porcelain white, black, red, orange, yellow, green and other colors . While this outer layer of gum is based on, you can also add other materials (such as nylon braid leather layer) to increase the beauty and durability.
