Terminal Blocks - Headers, Plugs and Sockets:

Terminal blocks are a type of electrical connection component composed of head, plugs and sockets. This type of connection component is mainly used to pass current or to interconnect signals. It achieves the connection and disconnection of electrical power by plugging and unplugging. Terminal blocks are the traditional wiring device in electrical technology, which is widely used in railways, power, machinery and other industrial fields.

Fundamental Working Principle

The working principle of terminal blocks is mainly divided into two parts: signal passing and terminal connection. For the complete form of the terminal, it can be divided into many types, such as direct connection terminal block, plug connection terminal block, spring connection terminal block and others. Terminal blocks can also be divided into two versions, one is strip connection, another is screw connection.

Application Field

In the application of the control system, terminal blocks mainly have the functions of signal conduction (including power and signal), electrical insulation, circuit interconnection, and so on. Common applications of terminal blocks are in many electrical systems, power systems, instrumentation systems and telecommunications systems.

Direct Connection

A direct connection terminal block is a terminal block designed for direct connection between core and core. In its design, male and female connections are installed between the two cores, and different terminals can be connected together without the need for any additional hardware. Furthermore, the connection of the cores to each other is reliable and the electrical contact is stable. This type of terminal block is suitable for connecting various device cores in the same line.

Plug Connection

The plug connection terminal block is a terminal block that is used to connect two wires in the same line. This type of terminal block is designed to ensure that the wire plugging port is parallel with the platen plane. This efficiently eliminates the possibility of two wires connecting to the same plugging port. Furthermore, the plugging port is also designed to facilitate the plugging operation of the wire.

Spring Connection

The spring connection terminal block usually refers to a terminal block designed for connecting two different lines. The design of this terminal block allows the user to use a spring instead of a screw to complete the connection of the two different lines. In other words, it allows two different wires or terminals to easily connect to each other by pressing with a spring. This design helps to save a lot of time when connecting two different wires or terminals.

Conclusion

Terminal blocks are an important electrical connection component. It can be used to connect different electric circuits in electronic systems, widely used in electrical, power, machinery and other industrial fields. Terminal blocks are mainly composed of head, plugs and sockets, mainly used for passing current or for interconnecting signals. Different kinds of terminal blocks have different working principle and application field, including direct connection, plug connection and spring connection.
