Terminal blocks are commonly used components in many electrical and electronic applications. They\'re largely responsible for the rapid connection and disconnection of terminals, cores, and wires. With the correct terminals, headers (connectors), and sockets, they can make all kinds of assemblies possible. The type 1986717-3 from Phoenix Contact is one such terminal block, and this article will explain its application fields and working principles.

Types

The 1986717-3 is a 3-pole touch-safe terminal block. This address two issues of safety and ease of use, as the terminals (connecting the input or output of controllers) have a "dead front" design meaning the terminals are safely recessed, reducing the risk of electrical shock. This is especially important in applications where human contact with the wires may be a hazard.

The 1986717-3 also features a spring connection mechanism which makes wire work a snap. It eliminates the need for screws or tools altogether, instead offering a simple push button which positively locks the wire and weakens the connection so it\'s easily removed.

Application fields

The 1986717-3 is most useful in applications where safety is a concern and where ease of assembly and service are important. It\'s particularly suited to wiring applications with a potential for human contact, such as medical equipment, mobile vehicles, and electrical appliances. It\'s also useful in wiring applications where consistency is essential, such as wire harnessing and machine control systems.

Working principles

The 1986717-3 terminal block has two different connection methods: manual and spring-caged. The manual connection is a simple, plug-in type connection which eliminates the need for additional tools or wiring. Simply insert the terminal and tighten the set screw to secure the connection.

The spring-caged connection on the 1986717-3 is slightly more complex and involves insertion of the wire into the cage. The cage then clips onto the base and locks into place. This is especially useful in instances where fast and accurate connection and disconnection of multiple wires are required.

Conclusion

The Phoenix Contact 1986717-3 terminal block is a great choice for a wide range of wiring applications. It simplifies the job of connecting and disconnecting terminals, cores, and wires. With its touch-safe design and simple connection methods, it helps ensure safety in areas where human contact may be a concern. Likewise, its spring-caged setup offers reliable, fast, and accurate connectivity.
