Terminal Blocks - Accessories

Terminal blocks, also known as terminal boards or strips are devices used for joining wires. They come in a variety of shapes and sizes and are commonly used in electrical systems of varying complexity for connecting wiring projects. Terminal blocks simplify the installation process and make the use of multiple connections easier and faster.

In 1859, Siemens developed a modular system of terminal blocks to achieve a successful connection between electrical wires. This system gained popularity and they have been the standard for wiring projects since. Many modifications and variations have been made to the original design since then, but the basic concept remains the same. Terminal blocks are most commonly used to connect two or more wires in a single circuit.

The application field of terminal blocks includes household applications, industrial and commercial applications, as well as scientific and research applications. Their versatility and wide range of uses make them an essential part in any cable management project or electrical wiring project.

In its simplest form, a terminal block is composed of two metal plates, which are connected to one another by an arm. One of the metal plates is connected to a power source, while the other metal plate is connected to the load, such as a light or motor. A terminal block typically contains several horizontal slots, which are used to feed wires into the connection. The wires are then clamped in place on the metal plates by a pair of parallel arms.

The working principle of a terminal block is based on the conductive properties of the metal plates. When a voltage is applied to the metal plates, the electric current flows between them. The conductor in each wire is then clamped in place on the metal plates, allowing the current to flow through the wire and to the load.

Terminal blocks are an important part of any cable management or electrical wiring project. They simplify the wiring process and make multiple connections easier and faster. Their versatility makes them applicable to almost any apparatus installation or wiring project, making them a popular choice among professionals and hobbyists alike.
