Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks are electrical components used to secure two or more conductor connections in a safe and reliable manner. They are commonly used in the manufacturing process and in the final assembly of electrical and electronic devices. The device consists of three essential elements known as headers, plugs and sockets.

Headers

The headers are what attaches the terminal block to the device or circuit it is connected to. These are the primary connections of the terminal block. Most terminal blocks have metal or plastic casing, with several slots for the contacts. Headers are usually secured with screw, bolts or rivets. Headers may also be bar-shaped or beveled, depending on the type of the application.

Plugs

Plugs are the peripheral components of the terminal block: they are exactly what’s needed in order to make the connection between the header and the device it is connected to. Plugs are made from conductive materials such as aluminum, steel, copper, etc. and are available in various sizes and shapes. Typically, plugs are either inserted or wire-wrapped into the header of the terminal block.

Sockets

The third and final component of the terminal block is the socket. As its name implies, it is the part of the device used to plug in or remove the plug from the header. Sockets are usually made of a softer, more malleable material than the plugs, allowing for easier insertion and removal. These come in various shapes and sizes; some feature a sliding or snap lock mechanism for an even stronger connection.

Application Field and Working Principle

Terminal blocks are typically used for a wide variety of applications, from electrical wiring to telecom connections. The most common are industrial controls, such as circuit breakers, relays, switches and control panels. They can also be used to provide power to test instruments, medical equipment and consumer electronic equipment.The working principle of a terminal block is quite simple: the plug is inserted into the header, and the connection is made when the socket is mated with the plug. The header then provides the electricity and/or data connection between the two elements. Secure connections are ensured by the use of twisted, spring or riveted pins.Terminal blocks provide a safe and reliable way of connecting two or more conductive materials. They are used in a variety of applications, from industrial control to consumer electronics. Headers, plugs and sockets are the three main components of the device, providing the connection and secure connections. They are also quite simple to use, as the principle is merely the insertion and mating of two components.
