1754128 Application Field and Working Principle
Terminal Blocks - Headers, Plugs and Sockets come with a variety of characteristics, which provide a wide range of applications and are therefore highly versatile. In this article, we will explain further details on their application field and the working principle behind it.
Terminal Blocks Overview
Terminal blocks are electrical connection elements for assembling printed circuit boards. They are mainly used in switch cabinets, control and power distribution systems. In the simplest form, they consist of two terminal strips and a conductor plate which contacts the two terminal strips.
Most terminal blocks have a pluggable design and are often used to connect signal and power cables to printed circuit boards. Terminal blocks are available in different sizes and shapes so that they can be used for various applications.
Application Field
Terminal blocks - headers, plugs and sockets can be used in a wide range of applications, such as machine wiring, switchgear and control, and data transmission systems. Terminal blocks can also be used to build up wiring in many cases, as they can be easily assembled on a printed circuit board.
The various headers, plugs and sockets are suitable for different applications. For example, headers are mainly used in device and system wiring, while plugs and sockets are used for signal and power wiring, for example. The plugs and sockets can also be used to connect different signals and power supplies.
Working Principle
The working principle of a terminal block is quite simple: two terminal strips are connected together by a spring-loaded metal plate. The connection is made by inserting two wires into the terminal block, with the spring loaded plate pressing the wires onto the terminals. This creates a mechanical and electric connection between the two wires.
The terminal block offers a greater amount of current than a wire-to-wire connection. This is because the spring-loaded metal plate is able to transmit a greater amount of current than two wires alone. Additionally, the spring-loaded plate is insulated, meaning that the current is not transmitted through the metal plate, but through the terminal strips.
