2967976 Application Field and Working Principle

Terminal blocks, also known as conductor terminals or contact terminals, are a type of electrical connector that facilitates connection between field wiring and electrical equipment. It is usually composed of a plurality of connection ports, a fixed frame, a movable connector and a plunger. Terminal blocks can be divided into plug-in types and non-plugging types according to the installation method. Jumpers are devices used to bridge different terminals and connections.

Application Field of Terminal Block

Terminal blocks are widely used in all kinds of electrical equipment in industry, agriculture, defense, aerospace, medical care and other fields, and are widely used in electric power, electric energy, communication, electronic instrumentation, computers, automation and control industries, and are extensively used in the majority of wiring fields. With the development of automation industry in recent years, terminal blocks are widely used in such fields as automation, process engineering and industrial control.

Working Principle of Terminal Block

Terminal blocks generally have a pluggable structure. During assembly, a plurality of interface pins connected to one side of each wire are inserted into the plug-in holes of the terminal block plug, and the other side of each wire is connected to a single contact on the conductive strip on the plug, thereby forming an electrical connection. When the contact strip needs to be changed or removed, the plug can be pulled out of the plug hole of the terminal block, and the pin is also naturally removed from the plug.

Working Principle of Jumpers

Jumpers are used for signal bridge connection. When two points or terminals of the same layer need to be connected, the jumper can be used to connect, and the jumper is placed in the parasitic capacitor area on the PCB to ensure that the circuit works normally without interference. After the connection, the jumper can be easily removed, and the resistance between the two terminals is very low. Jumpers are generally used to adjust the current, isolate two parts of the circuit, and protect sensitive components.
