Terminal blocks are electrical connectors which are used to provide fast and secure connection point. The terminal blocks which are popularly referred to as wire to board connectors, allow for fast connection between two wires. These connector can also be used to facilitate the connection of wires to various components on a board such as electronic chips and capacitors. The terminal blocks are mainly used in the application of automation, computer engineering, industrial control, and power electronics.The type of terminal block which is classified as wire to board, is designed for the purpose of permanently connecting wires to a printed circuit board (PCB). These connectors are conveniently designed with a horizontal or vertical pin configuration. There are also more complex structures with multiple rows of pins available. Possible pin spacing for wire to board terminal blocks includes 2.54mm, 5.08mm and 7.62mm among others.The working principle of terminal blocks involves making a secure connection between the wires and the printed circuit board, using the appropriate insulation displacement contact (IDC) technology. The optimal IDC tool is used, depending on the type of material which forms the terminal block. For example, for insulation displacement contacts which are made of copper, a copper IDC tool is employed. It is essential that the IDC tool precisely cuts into the conductor which allows for safe, reliable and durable electrical contact. The terminal block structure typically has grooves which are to be filled with the IDC tool which pierce through the insulation material when force is applied onto them.The other parts of the terminal block may involve common differential contact technology or fixed compression spring technology. Common differential contact technology involves two conductor elements which are arranged in the terminal block and which make contact with the wires. The differential contact makes springs which can expand. The wire is inserted into the open spring and when the spring closes, it will cut away the insulation and penetrate to the conductor, providing a secure electrical contact. Fixed compression spring technology on the other hand, involves a contact spring which is fitted into a hole in the terminal block. When the wire is inserted into the spring, the spring will compress against the wire and create a secure connection. The wire is then locked in place with the combination of the spring force and the structure of the terminal block.The advantages of terminal blocks include fast installation, secure electrical connection, large variety in pin-spacing choice, compact size and versatility in application. The wire to board terminal block is particularly beneficial due to its versatility in application which includes the termination of various shapes and sizes of wires. Moreover, to facilitate a connection of longer cable lengths, there are also types of terminal blocks which contain a bridge module so that multiple terminal blocks can be connected together. The terminal blocks are widely used in many modern day electronics, including computers, home automation, industrial machines and even in robotics. They are preferred for these applications due to their ability to withstand high current capacity, extreme temperatures and shock and vibration. Other than that, terminal blocks are known to be cost-effective and low in maintenance.In conclusion, terminal blocks are widely used in the industrial domain for the secure and fast connection of wires to a printed circuit board. The main application includes automation, computer engineering, industrial control and power electronics. One of the common types of terminal blocks is the wire to board connectors.Their advantages include fast installation, secure electrical connection, large variety in pin-spacing choice, compact size, versatility in applications and ability to withstand extreme conditions.
