There are a variety of connecting lines on the market, so what are the common connecting lines?

1, computer cable

The computer cable is a cable that connects various external devices to the host computer, and is divided into a display cable, a power cable, and a data cable. The power cord is mainly to supply power to the device and to charge the battery. The display cable is used to connect the host graphics card output port or the motherboard display output port to the display input port. The data line is mainly connected to an external input, output or storage device through a computer serial port and a parallel port and a USB interface to achieve mutual information transmission. For example, the printer and the computer need to connect the printer USB cable, the mobile phone and the computer need a mobile phone USB cable, and the like.

2, printer cable

The printer cable is the cable used to connect the printer to the computer. It is divided into two types: USB print cable and parallel port print cable.

3, display cable

The display cable includes a data cable that connects the host to the display and a power cable that connects to the power supply.

Common data cable types are: HDMI cable, VGA cable, DVI cable, and the Display Port (DP) and Mini Display Port cables that have become popular in recent years, as well as the latest Thunderbolt (mainly for Apple). Mac product line after 2010).

Common types of power cables are: the interface has three pins and two pin types.

4, USB print cable

The port is connected to the USB port and the PIN5 port is connected to the printer. The transmission speed is fast, it can be hot-swapped, and the printer driver can be loaded from the computer after the connection is completed.

5, parallel port print line

Refers to the print line that uses parallel transmission to transfer data. Because this interface is easily damaged and the transmission speed is slow, it is basically replaced by the USB interface.

6, male and female cable

The meaning of the male and female connecting lines is very simple, that is, a connecting line composed of a male connector and a female connector is called a male and female connecting wire. Common male and female cables are commonly used in DC lines and terminal busbars for LED lights and drive power connections. The DC male busbar is injection-molded, that is, the DC head is welded and then injection-molded. The terminal busbar is cold-pressed on the wire and then inserted into the male and female connectors to become the terminal busbar. The male busbar is also convenient for maintenance and maintenance. For example, the lamp driver is broken, and the driver can be directly replaced without welding.

7, PCB board interface

PCB boards are used in every electronic product, except for capacitors, resistors, ICs, diodes, and triodes. The most important thing is the needle holder that can be connected to the wire. By soldering the needle holder, and then leading out the line with the connector, it is called the connection line. The advantage of the connection line is that it does not need to be soldered and can be cold pressed by the terminal machine. carry out. Connection cable with connectors for easy maintenance and commissioning. In the equipment, if the line is short-circuited, we only need to change the line of the same specification line, no need to solder with a soldering iron, which is environmentally friendly and simple. Bailev specializes in a variety of cables and offers a variety of solutions. The PCB board connection line, also known as the terminal connection line, is a connection line made of a needle holder, a plastic case, a terminal, a wire, and the like, and is widely used in the interior of the device. It is also a key point that cannot be ignored.
