Terminal blocks - Headers, Plugs, and Sockets, are part of the 11.5.27.00 application field and an effective tool for connecting electrical equipment components and electronic circuits. Terminal blocks are used to provide electrical connections between two conductors within two or more circuits in an efficient, controlled, and cost-effective manner.

Terminal blocks consist of two or more uniformly sized connecting points in a linear or circular arrangement, known as "headers." Each header is usually made of a metal material such as brass, copper, or nickel-plated zinc, and they are attached to an insulated base or lug. Depending on the application, headers can be designed with multiple, removable, interchangeable parts that can accommodate different wire sizes or circuit configurations. Other common features of headers include retaining clips, cable clamps, cable strain-relievers, and power distribution terminals.

The plugs, standoffs, and sockets that are used with the header terminals provide the ability to connect, disconnect, and replace electrical connections without needing to cut or strip the wires. The plugs are inserted into the headers and are usually made out of various types of metals, plastics, or even rubber. Standoffs are typically used to keep the plugs securely in place, and to reduce the incidence of wires shorting out. Sockets are often used to ensure the proper matching of plug and header terminal, as well as provide controlled contact pressures and electrical connection.

Terminal blocks provide significant electrical and safety advantages compared to soldered connections. They also save time and money, as they allow for easy inspection of circuitry and provide a simpler and less expensive means of maintenance. Additionally, terminal blocks allow for the addition of components or circuitry without complicated rewiring, and ensure secure connections if parts are disassembled/reassembled. By helping to effectively connect electrical devices, terminals are an essential part of any electronic circuit.
