Wire harnesses are generally composed of wires, connectors, sheaths, insulating materials, etc. Below, the cool breeze of Xuanye Connector will discuss with you what kind of role relationships the signal wires, power cables, and connectors in the wire harness have.
The signal line, as the name implies, mainly refers to the line used to transmit sensor information and control information in the electrical control circuit. The signal line is often composed of multiple cables as one or more transmission lines, or it can be a printed line arranged in a printed circuit. With the continuous advancement of technology and applications, the signal line has been developed from a metal carrier to another Carriers, such as optical cables, etc. Signal lines for different purposes often have different industry standards to facilitate standardized production and application.
A power cord is a wire that transmits electric current. The usual way of current transmission is point-to-point transmission. Power cords can be divided into AC AC power cords and DC DC power cords according to their use. Generally, AC power cords are wires that pass high-voltage alternating current. Such wires require uniform standards to obtain safety certification due to their high voltage before they can be officially produced. The DC line basically passes the low-voltage direct current, so the safety requirements are not as strict as the AC line, but for safety reasons, countries still require unified safety certification.
The biggest difference between a signal wire and a power wire is that the signal wire transmits analog or digital signals, and the power wire is used to transmit current.
The signal line refers to the line that transmits data, and the power line refers to the circuit that provides power. In fact, the signal line also runs electric signals, but they are regular, arranged, and informative electric signals. The power cord only carries DC current with a fixed voltage value.
In electronic equipment, the function of the connector is to provide a separable connection device between the electronic systems without causing signal absorption, attenuation, and power loss to the performance of the system. A wire is connected.
The three of them can exist independently or coexist. If there are signal and power transmission requirements in electronic products, how can there be fewer connectors? Therefore, these three are interdependent and coexist, and they are indispensable in electronic products.
