Terminal Blocks – Headers, Plugs and SocketsTerminal blocks are electrical connection points in an electrical system which allow for the easy connection of wires within a circuit while referencing the connection with its currently assigned name. They can be used in a variety of different systems, such as solar and automotive, and typically connect multiple circuits via a series of threaded plates.Headers, Plugs and SocketsHeaders are generally used to connect circuits together and provide a secure connection with minimal effort from the user. This is achieved by the rotating locking mechanism that assists with the connection of the plug to the header. Generally they are available in two variants: one which provides a surface mount design for PCBs and one which is more suitable for connecting electrical cables. In general, headers are constructed from either plastic or metal, depending on the environment in which they are used. The pins will be exposed and the internal contacts are typically plated with a soft metal or alloy. The spacing of the pins will generally correspond with the pitch of the pins of the plug and socket. In some instances, headers may also feature additional features such as current-limiting resistors or diodes to provide additional protection for the circuit.Plugs and sockets are usually connected to headers together in order to provide an efficient way to connect two circuits together. The plugs and sockets are generally constructed from either plastic or metal and should have good electrical insulation properties. They are usually available in various sizes and designs, depending on the requirements of the application.The plug part of the assembly will often feature a wire or terminal to which the electrical cable can be connected. This is then connected via a rotating lock to the corresponding socket. The socket will also feature a series of contacts which align with those of the plug and seal its connection once rotated.Working PrincipleThe working principle of terminal blocks is pretty simple and relies on two main principals: one being the use of a rotating lock to secure the connection and the other being the electrical contact points. For the lock, the plug will feature a corresponding two-part locking mechanism which is connected to a rotatable bar. When the plug is inserted into the socket, the rotatable bar will move and secure the plug in position. The rotating lock will also provide an effective electrical connection between the pin contacts of the plug and the socket.The electrical contact points will be plated with a contact-friendly metal or alloy to ensure a good connection between them. In some cases, the contact points may also be surrounded by an insulating layer of plastic or rubber in order to protect them from environmental damage. In summary, terminal blocks are an effective and versatile way to securely connect circuits together in a variety of applications. They are relatively easy to use and a secure way to ensure the closure of a electrical circuit.
