Terminal blocks have been utilized within various applications since the 1950’s. Ranging from industrial automation to the aerospace industry, they provide significant advantages in comparison to hand wiring by allowing a quick installation, saving time on wiring. The applications and uses of terminal blocks are numerous, as well as the sizes and types available.The header type, plug and socket terminal blocks provide quick connections while improving the signal integrity, maintaining consistent contact over multiple mating situations. Within the electronic industry, headers and plugs are often used as custom connectors in multiple purposes, while socket terminal blocks are mainly used in PC boards, allowing multiple connections. This type of terminal blocks is also known as board-to-board connectors, and can be found in a variety of applications such as data networking equipment and telecommunication systems. The headers and plugs type can also be utilized in the wiring and patching of machines and machines to a network.In general, terminal blocks have two parts: the first part is the conductor, either a collet, terminal bar, screw, nut or a combination of them. The other part is the insulator, normally of polyamide or another plastic material that can handle higher temperatures. Advantages of this type of terminal blocks involve being able to change the configuration, removing or adding lines, saving time and resources. In the case of the headers and plugs, the insulator is designed as a shield which re-routes and captures the signal.Whether it is plug-and-socket or screw terminal blocks, the principle is the same. The wire is connected to the terminal block by driving a force onto the conductor, making it clamp onto the wire and thus providing a stable connection. The insulator holds the wire in place, ensuring a solid connection between the wire and the terminal block.The sockets are often defined as modular terminal blocks. They come in various shapes and sizes, having round, square or rectangular sockets that are covered by an insulating base plate. These terminators feature a special tongue and groove design that connects them together, instead of pushing them into the board.Plugging the connector onto the board is easy, but it does need care and attention to correctly align the pins. Socket terminal blocks require more connection work and need the features to be connected in order; ensuring a proper connection with the mating terminal block.Headers and plugs are used when engineers need an easier way to join electrical circuits. They are considered the most popular way to join electronics, from simple circuit boards to complex ones. Headers give the convenience of having a different set of pins for the different higher current connections. With headers, wires can be securely attached using spring loaded clips.Header type terminal blocks are designed for a wide variety of connections. It also provides advantages in terms of performance and cost savings, as there are fewer terminal blocks required to cover multiple wires. Plugs can be designed for tightly bending to fit in the required space. Plugs also have the advantage of being made with precision, whereas the wires need to be stripped and terminated by hand.These type of terminal blocks when used with screw termination provide a strong connection, as the screws help feeding even and consistent pressure to the conductor, thus achieving a tight connection. The screw tightening also decreases the temperature variations by decreasing the electrical resistance within the wiring channel, providing a more stable electrical connection.Unlike headers and plugs, the socket type has different variations. There are the U-shaped sockets, having four contacts and two forks, which are used for standard electrical functions, or the spring covers that are used for electrical appliances. Apart from electric applications, socket type terminal blocks are used in a wide range of industrial purposes, such as housing mechanical parts and connecting them to pressure points.Terminal blocks, in summary, are a straightforward way to ensure a quick, secure and reliable connection between components. The applications of these are far and wide, from the simplest screw connection for a home appliance to complex solutions in industrial automation. Proper selection is key for achieving the desired performance and utilization, and ensuring the safety of the devices.
