Terminal Strips and Turret Boards

802 application field and working principle are central to understanding the use of terminal strips and turret boards. Terminal strips, also known as terminals, are electrical components that provide a way to connect and disconnect wiring to an electrical power source. The strip contains two parallel rows of mounting holes with corresponding male and female terminals. The terminals provide both mechanical and electrical contact with the wiring. Turret boards are similar in that they provide a way to connect and disconnect wiring to an electrical power source; however, instead of a strip of mounting holes, a turret board consists of finger-like posts called turrets. Each turret is surrounded by metal contacts and provides a secure way to mechanically and electrically connect the wiring to the power source.

Uses and Benefits

Terminal strips and turret boards are ideal for use in a variety of applications such as wiring control panels, power distribution systems, and circuit board assemblies. Their use provides a range of benefits including:

• Secure connections: Both types of components provide a secure way to mechanically and electrically connect wiring to a power source, eliminating the risk of loose contacts and arcing from exposed wiring.
• Easy installation: Both terminal strips and turret boards are quick and easy to install, saving time and money on installation costs.
• Durability: Terminal strips and turret boards are designed to support heavy loads and resist corrosion, which ensures their long-term performance and reliability.
• Cost-effectiveness: Both terminal strips and turret boards are relatively inexpensive, making them an attractive option for cost-conscious applications.

Materials and Configurations

Terminal strips and turret boards are available in a variety of materials, ranging from plastics and non-metallics to brass and copper. Each material is suitable for different applications, depending on the requirements. For instance, plastic and non-metallic materials are ideal for low-voltage and signal applications, whereas brass and copper are better suited to high-voltage applications. Furthermore, depending on the application, the mounting holes and terminals can be configured in a variety of orientations, such as top-entry, side-entry, and reverse-entry.

Safety Considerations

When using terminal strips and turret boards, it is important to consider the safety of those working with the components. Installing the terminals or turrets in the wrong orientation can result in electric shock or fire. As such, it is important to ensure that the connections are properly and securely made. Additionally, it is important to use the correct size terminals or turrets for the wiring, as too small of a size will not make a secure connection.

Conclusion

Terminal strips and turret boards are ideal for use in a variety of applications, offering secure connections, easy installation, durability, and cost-effectiveness. Their use should, however, be undertaken with safety in mind, as incorrect installation or use of the wrong size terminals or turrets can lead to electric shock and even fire.
