Machining Computer Cable Includes (Display, Power Cord, USB cable)
- PRODUCT DETAIL
The computer cable is the cable that connects various external devices to the computer host. Divided into display cable, power cable and data cable. The power cord is mainly to provide electricity to the device and charge the battery. The display cable is used to connect the output port of the display card of the host computer or the display output port of the main board to the input port of the display. The data line is mainly connected with external input, output or storage devices through the computer serial port and parallel port and USB interface to achieve the purpose of mutual information transmission. For example, a printer USB cable is required to connect a printer to a computer, and a mobile phone USB cable is required to connect a mobile phone to a computer.
Display cable
The display cable includes a data cable connecting the host and the display, and a power cable connecting the power supply.
Common data cable types are: HDMI cable, VGA cable, and DVI cable. There is also a DP cable for notebooks
Computer power cord
Common power cable types are: The interface has three-pin and two-pin types.
USB cable classification
According to the size of the connected device, the connector is divided into: small, medium, and large.Trumpet: Mainly used on some small mobile storage devices. Some mobile phones or cameras, such as mp3 or mp4, also use a small size, but very few.
Medium: mobile phones, psp, nds, etc.
Large size: U disk, mobile hard disk, multi-function TV, printer and some special ones, which have various shapes, which are different from standard USB.
Data line interface
USB is classified according to the function of the interface data line: without IC, with IC, special chip.
1. Without IC: There is no central control chip, you must plug in your mobile phone to recognize the line, and the price is cheap.
Typical models: Samsung CDMA series, D500 series; Motorola E398 series, V3 series; Nokia DKU-2; NEC N720 series; Siemens 65 series and so on,
2. With IC: With a central control chip, the common chip models are 2303, 2101, 3116, and the line can be identified without plugging in a mobile phone or computer. Since the price of an IC is 10 RMB, the price is more expensive than the one without IC. The working principle of the data cable with chip is USB to COM, which converts the USB interface into a serial port and displays it on the computer.
Typical model: Samsung E638 series, D418 series; NEC N610 series; Siemens 25 series, 55 series; Sony Ericsson mobile phone data cable; Panasonic mobile phone data cable; Lenovo mobile phone data cable and so on.
3. Special chip:
Non-ordinary popular chips, dedicated special model chips such as: DKU-5, CA-42, DCU-11 and so on.
Note: Don't mistakenly think that the quality with IC is good and the quality without IC is poor. The actual product with or without IC needs to be produced according to the applicable model of the mobile phone.
USB data line characteristics
USB data cable is the mainstream, the advantage is that it is convenient, fast and stable, and supports all types of equipment;The disadvantage is that the price with IC is slightly higher, and some data lines do not support reinstalling system functions.
There is also a USB high-speed cable, which transfers files several times faster than a general USB cable. The speed of USB file transfer is not only based on the speed of the USB cable, but also related to the speed of your computer's hard disk, memory, and mobile storage devices! And supports hot swap.
USB data cable difference
There are two versions of USB. The maximum data transfer rate of USB1.1 is 12Mbps, and that of USB2.0 is increased to 480Mbps. Note: The b here means Bit, 1MB/s (megabytes per second) = 8MBPS (megabits per second), 12Mbps = 1.5MB/s. The physical interfaces of the two are exactly the same, and the difference in data transfer rate is completely determined by the PC's USB host controller and the USB device. USB can provide up to 5V, 500mA power to the device through the cable. In addition, some USB-related products on the market marked as USB 2.0 Full Speed are actually USB 1.1, while those marked as USB 2.0 High Speed are real USB 2.0.
