Data line connecting wire
Technical Field

Background
Since release of USB V0.7 at 11/1994, USB version has been developed for many years, and has been developed to 3.1, becoming the standard extension interface in computers in the twenty-first century. Currently (2016), a mainboard mainly adopts USB2.0 and USB3.0 interfaces, and USB versions can be well compatible with each other. USB uses a 4-pin (USB3.0 standard is 9-pin) plug as a standard plug, and all peripherals can be connected in daisy chain form, and 127 external devices can be connected at most without losing bandwidth. USB requires support from three aspects, host hardware, operating system and peripherals, to work. In the twenty-first century, a control chipset supporting USB function is generally adopted for a motherboard, a USB interface socket is also installed on the motherboard, and besides a socket of a backplane, a USB pin is reserved on the motherboard and can be connected to the front of a case through a connection line to serve as a front USB interface for convenient use (note that, during wiring, the motherboard specification is carefully read and connected according to a drawing, and tens of millions of devices cannot be mistakenly connected to cause damage). And the USB interface can also realize the dual-computer interconnection through the special USB connecting line, and can expand more interfaces through Hub. The USB has the advantages of high transmission speed, convenience in use, support for hot plug, flexibility in connection, independent power supply and the like, and can be connected with a mouse, a keyboard, a printer, a scanner, a camera, a charger, a flash disk, an MP3 player, a mobile phone, a digital camera, a mobile hard disk, an external CD/floppy drive, a USB network card, an ADSL Modem, a Cable Modem and other almost all external devices.
Although the use of the USB data cable is very widespread, the frequent plugging and unplugging of the USB plug causes the wires between the wires and the USB data head to be very easily broken; the transmitted partial data needs to keep the stability of the USB mounting position due to higher requirement on data precision, so that unstable signals are avoided; in addition, some precision instruments and the joints of the USB data lines are also required to avoid the interference of external signals.
