A computer connection cable is a cable that connects various external devices to the computer host, divided into a monitor connection cable, a power cable, and a data cable. The power cord is mainly used to provide power to the device and charge the battery. The display cable is used to connect the output port of the host graphics card or the display output port of the motherboard to the input port of the display. The data cable is mainly connected to external input, output, or storage devices through computer serial and parallel ports, as well as USB interfaces, to achieve the purpose of exchanging information. For example, connecting a printer to a computer requires a printer USB cable, connecting a phone to a computer requires a phone USB cable, and so on.
100% digital uncompressed, without the need to convert pure digital images and sound directly from the source (visible and audible). Video and audio signals maintain the best digital quality from the output device to the display device. Sound and images provide the bandwidth for HDTV
The general arrangement of colors for USB cable interface definition is: red, white, green, black, defined from left to right: red - USB power supply: marked with the words - VCC, Power, 5V, 5VSB green - USB data cable: (positive) - DATA+, USBD+, PD+, USBDT+white - USB data cable: (negative) - DATA -, USBD -, PD -, USBDT+black - ground wire: GND, Ground
1. COM interface, also known as serial port, is connected to the back of desktop computers and is currently being phased out. The advantage is that the price is low and it supports flashing (some mobile phones can only use serial cable flashing); The disadvantage is that it is extremely inconvenient to remove and unplug, does not support laptops, and the transmission speed is also relatively slow. 2. USB interface is currently the mainstream, with the advantage of being convenient, fast, and stable, supporting all models of computers; The disadvantage is that the price with IC is slightly higher, and some data cables do not support the flash function.
China's connecting lines are mainly at the mid to low end, while the proportion of high-end connecting lines is still relatively low, but demand is growing rapidly. In the field of high-end connection cables, computers and peripheral devices have the largest market share, and the market share of connection cables for automobiles and medical devices is also relatively high. In China, the market share of automobile connection cables is about 20%. However, the rapid popularity of 3G mobile phones has led to a rapid growth in demand for high-end connection cables. Currently, the connection cable spacing used by 3G mobile phones is only 0.3mm. With the development of mobile products led by mobile phones towards miniaturization, thinness, and high-performance, the connection between display screen components and substrates has become more complex. In this context, the demand for narrow spacing, low back, and multipolarity between the substrate and FPC connection lines is more urgent, especially for the ultra-thin requirements of mobile phones, which require ultra-low back of the internal connection lines. In order to achieve low back, narrow spacing, miniaturization, multipolarization, and high reliability of products, various manufacturers have adopted simulation technology for in-depth research and development.
Easy to learn technology: The so-called USB3.0 is the new generation of USB interface, characterized by a very fast transmission rate, theoretically reaching 4.8Gbps, which is 10 times faster than the current 480Mbps High, Speed, and USB (referred to as USB2.0). Its appearance is basically the same as the current USB interface, and it can be compatible with USB2.0 and USB1.1 devices.
