Terminal blocks, also known as barrier strips, are electrical connection points typically used in industrial control systems. They are designed to provide a safe and secure connection while protecting exposed wires from voltage and current. The design of the terminal block also helps to maintain a good electrical contact between a variety of industrial controllers and components. This article will discuss the application field and working principle of terminal blocks.

Application Field

Terminal blocks are useful in industrial control applications of any kind where a secure connection must be made. These blocks can form interconnections in large-scale automation systems, control cabinets, and compact electronic systems. In addition, terminal blocks provide a quick and easy power distribution in machine environments while also reducing hazardous wiring. These blocks are also commonly used to control and measure powder and liquid levels, as well as monitoring and regulating temperature.

Terminal blocks are also used in mechanically operated systems such as robotic arms and valve activation systems. The terminal blocks provide a reliable transmission of signals from the controller to the components, as well as a secure solder joint for connection. Furthermore, a large selection of terminal block collets, spacers and other installation components are available to suit any application.

Working Principle

Terminal blocks utilize a broad range of connector designs, such as screw terminals, pluggable terminals, and pcb-style components for making electrical connections. The most common design utilizes a block-like construction with a reciprocal screw-type connector to join two conductors. Connecting the conductors to the block requires the user to place each wire, or a group of wires, into the appropriate section of the terminal block and then terminate the connection with the right sized screw. The screws are then tightened securely to ensure proper contact between the conductors and the block.

Terminal blocks can also accommodate a variety of other connection types such as spring-cage, mechanical, and solderless connections. Spring-cage and mechanical connections involve slots on the block that the conductors are inserted into. The connection is then secured with a clamping device or some other form of latching mechanism. Solderless connections have the same slot-type design but utilize a specialized connector that is inserted and then locked with a pre-set tightening mechanism to ensure the connection is secure.

In addition to the traditional terminal block designs, manufacturers now offer a variety of specialty blocks that can provide advanced functionality. Many of these newer designs are designed to improve safety, efficiency, and versatility on the job site. For example, the Unilogik line of terminal blocks has an integrated protection system that helps protect the terminals from short-circuiting and external electrical noise.

Conclusion

Terminal blocks, also known as barrier strips, provide an efficient and secure electrical connection for a variety of industrial applications. These blocks are primarily used as a secure power distribution tool in all types of machinery and they come in a variety of different designs to accommodate different types of connections. From screw terminals to spring-cage and solderless connections, terminal blocks offer a wide range of features to suit any application.
