Terminal blocks or headers, plugs and sockets are an essential part of most circuit designs. It is used to connect electrically-powered devices to circuits within an application. It also helps keep wires from getting tangled and overloading the circuit. The 1943687 application field and working principle are both varied and complex.

Terminal blocks are used in various industries, including in industrial manufacturing; in installation and maintenance engineering; in the automotive industries; in the medical industry; in electrical/electronic installations; in telecoms/data communications; and in connection and distribution of power supply systems.

Terminal blocks typically consist of two or more connecting modules with a spring-loaded bridge or a sliding bridge that connects two or more individual terminals. Depending on design, these devices allow various modes of connection, for example, tension-clamp technology, spring-clamping technology, but also simple screw-penetrable terminal blocks. The working principle of terminal blocks is relatively simple: A terminal block connects two or more wires by forming a link between the wires. The interlocking features of terminal blocks help increase reliability and reduce the risk of a faulty connection.

To use a terminal block, you first need to insert the cable into the terminal block. Depending on your requirements, you may need to connect the terminals to a power supply or to other wires within the terminal block. Once the wires are connected to the terminal, the spring-loaded bridge or sliding bridge will form a complete connection, ensuring that the electric current runs uninterrupted from one side of the terminal block to the other.

In addition to connecting electric devices, terminal blocks are also used to protect wires from electrical surges or safety hazards. For example, a fuse block may be fitted to a terminal block to ensure the protection of the cable from any potential overloads. Additionally, some terminal blocks may also feature signaling lights or indicators for controlling and managing circuits. This ensures electrical safety and helps reduce any risks of electric shock.

Terminal blocks provide a simple and cost-effective way to connect electrical devices and thus form an integral part in a variety of industries. Their varied components, different wiring arrangements and ability to protect wires from potential overloads make them ideal for many electrical power distribution and signal transmission applications.
