Terminal blocks commonly referred to as headers, plugs and sockets, are simple and compact electrical connectors which provide a reliable and efficient connection between two components of an electrical circuit.

The design and construction of terminal blocks varies depending on their use but generally they consist of a contact element or pin, a plastic housing and additional components. As terminal blocks are usually used in relatively demanding applications, the design needs to be robust and provide a high quality connection between the two components. In situations where there is a lot of vibration or movement, the terminal block also needs to be able to accommodate this without loose connections or breakages.

One of the most common uses for terminal blocks is as the connector between a switch and a wire. This application takes advantage of the benefit of being able to disconnect the two without any wiring or soldering. It also provides a secure connection which will usually withstand the small amounts of vibration and movement which are typical in many environments. In other applications, terminal blocks are used as the connecting point between two electrical components in an electrical circuit, for example connecting a switch to a motor.

The working principle of terminal blocks is relatively simple. Electricity is transmitted from one connecting point to another through the contact element which can be a copper pin, a brass screw or a spring. The contact element is surrounded by a plastic housing which has slots which enable the connector to be clamped onto a wire or cable. This connection is then made secure by tightening a screw or lock, which applies pressure to the contact element and guarantees the connection.

Terminal blocks are available in a wide range of sizes and materials, dependent upon the exact application, and some are rated for specific voltage and current requirements. Different types of terminal block connectors have different designs due to their specific application. These connectors may include extra components such as components to switch off the electrical current, to protect against overload, to prevent shock and to dissipate heat generated from the electrical current.

1956289 terminal blocks provide everything from simple plug-and-socket applications to device level terminal blocks which require accurate measurement and control of electricity and other environmental conditions. They are commonly used in the industrial, automotive, aerospace and power industries where the device needs to be a reliable source of electricity. Whether it is transmitting power, managing electricity or providing a reliable way to connect electrical components, 1956289 terminal blocks are designed to provide a safe and efficient solution.
