Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks are connectors that are used to connect electronic components and routes signals and power between them. The different types of terminal blocks include headers, plugs, and sockets. This article will describe the application field and working principle of these types of terminal blocks.

Headers

Headers are terminal blocks which are used to interconnect electronic components and to route signals and power within a circuit. They consist of male rows of protruding prongs or pins that are designed to make contact with circuitry. Headers are commonly used in the electronic industry and are suitable for a variety of signals, including digital and analog. They are widely used in applications such as computers, audiovisual equipment, and other industrial controls.

Headers are usually available in two formats. These are male headers and female headers. The male header has a row of pins which protrude from the base, while the female header has a row of sockets which accept male pins. The pins and sockets are designed to provide secure electrical connections.

Plugs and Sockets

Plugs and sockets are terminal blocks that are used to interconnect two pieces of electrical equipment. They consist of a male plug which is inserted into a female socket. There are different types of plugs and sockets available, including AC and DC power connectors, telephone connectors, RCA connectors, headphone connectors, and others. The plugs and sockets are designed to transfer signals such as audio, video, power, and other types of signals and are available in different sizes and configurations.

The plugs and sockets are designed to provide a secure connection and are available in single-pole or multi-pole configurations. The plugs and sockets are able to carry different types of signals and can be used for a variety of circuits and systems. The plugs and sockets can also be used in a variety of applications, including industrial control systems, telecommunications systems, and automotive systems.

Working Principle

The working principle for terminal blocks such as headers, plugs and sockets is relatively simple. They are designed to provide a secure and reliable connection between two or more components. The pins/prongs of the headers are designed to make contact with the circuitry, while the plugs and sockets are designed to be inserted and removed from the socket in order to make a secure connection. When the connection is made, the pins make contact with the circuitry, allowing signals and power to flow between the components.

The connections between headers, plugs and sockets are designed to be secure and reliable. The connectors are usually constructed from high-hot wire with a good insulation that does not allow any signals to escape or enter the connection. They are also designed to provide a low resistance connection, meaning that a low voltage and current is present between the terminal pins.

Conclusion

Headers, plugs and sockets are terminal blocks that are used to connect two or more electrical components and to transfer signals between them. They are widely available in a variety of formats and are suitable for a variety of signals and applications. The working principle for headers, plugs and sockets is relatively simple and they are designed to provide secure and reliable connections at low voltages and currents between two or more components.
