Terminal strips and turret boards have been used for decades to connect electrical circuits. These devices have evolved over time, finding applications ranging from audio and industrial control systems to telecommunications and home automation. While the basic principles of these devices remain unchanged, their implementation and applications have grown significantly in recent years.The purpose of terminal strips and turret boards is to provide electrical terminals in order to enable connectivity between different components of a circuit. A terminal strip is used to connect two or more wires to the same point in a circuit. The strip typically has a set of metal contacts (usually copper or nickel plated) which form one of several types of electrical connection. The strip is mounted on an insulating base, usually plastic or fiber board, and can feature binding posts or screws for connecting wires.A turret board is a terminal strip featuring turrets, or raised metal contacts, that accept wire ends. Each turret has a specially shaped hole that securely grips a single wire, creating an electrical connection without soldering or other attachment methods. Connectors or printed circuit boards are placed in the board which form the circuit nodes for the connected wires. Both single and multi-strand wire can be used on these boards, with different types of insulation being used such as heat-shrinkable tubing or hot-melt adhesive.Terminal strips and turret boards are used in a variety of applications. The most common of these are audio and industrial control systems. Audio systems use terminal strips or turret boards to connect speakers to power amplifiers, and to join together components within a single amplifier. Industrial control systems use similar connections to enable electrical current to flow between components in order to control the speed and other operations of machines.Telecommunications and home automation are two other fields where terminal strips and turret boards are used. Within telecommunications, the strips and boards can be used to join together multiple telephone lines. This allows for more efficient communication between different parties. Within home automation, these same terminals are used to join together different appliances within a home, allowing for simple and efficient control over household tasks.Terminal strips and turret boards today feature a wide range of features and technologies. These include pre-tinned connectors to facilitate wiring and connections with other devices. They can also feature quick disconnect terminals or faston terminals to allow for easy connection and disconnection. Additionally, a variety of insulation materials are used on the contacts to help ensure the connection doesn’t suffer from wear and tear or corrosion.In conclusion, terminal strips and turret boards are devices that are widely used in a variety of applications. They are used to connect electronic components and circuits, and provide an efficient way to do so. They feature a variety of features including quick-connectors, insulation materials, and pre-tinned contacts. As technology continues to develop, the use of these devices is only likely to increase.
