Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks, also known as terminal boards, are mechanical connection devices enabling the connection of several wires. They are classified into headers, plugs and sockets, each of which has a different use and working principle.

0395324513 Application Field and Working Principle

Terminal blocks are primarily used in industrial applications, such as in the control systems of automotive and industrial plants, in power distribution and electronics assembly and production. The working principle of terminal blocks involves a metal contact plate, which is connected to a wire that has been inserted into a corresponding hole. The contact plate penetrates the insulation of the wire and measures the voltage or current of the wire, which is then transferred to a connector located at the rear of the terminal block. The connector then transfers the signal to the system which it is connected to.

Headers

Headers are the base components of terminal blocks and their primary purpose is to hold the contact plates and their respective wires. Headers are often sold in modular kit form which consists of a variety of headers, contact plates and associated components. This modular kit system simplifies the design and installation process of terminal blocks, as it eliminates the time consuming task of wiring individual components.

Plugs and Sockets

Plugs and sockets facilitate the electrical connection of individual wires and are commonly utilised in the automotive industry. The plug is the male part of the connector, which transmits an electrical current to the socket. The socket connects to a wire harness, which in turn connects to other electrical systems. The socket is designed to ensure that the wires are securely held in place with a mechanism which latches onto the pins of the plug. This minimises the risk of the wiring becoming loose or disconnected.

In conclusion, terminal blocks are useful tools used primarily in industrial applications. They come in the form of headers, plugs and sockets, each of which has a different use and working principle. Header components are used to hold contact plates and their respective wires and plugs and sockets are used to facilitate an electrical connection between individual wires. Due to the modular kit system, terminal blocks are both simple and efficient to install and design.
