Introduction

Terminal blocks, also known as barrier blocks, are devices used to electrically connect one or more electrical circuits. They are also used to securely terminate wires and provide an easy means to isolate, connect, and disconnect them. Terminal blocks provide an effective solution to simplify and improve the wiring of equipment. In 2015, manufacturers began using advanced application fields and working methods for terminal blocks.

Applications

Terminal blocks are used in a variety of settings and for a variety of purposes. These devices are suitable for use in both wire-to-wire and wire-to-board connections. Typical applications include but are not limited to: distributed control and power systems; lighting, heating and air conditioning systems; industrial automation systems; domestic appliance controls; and medical equipment. Terminal blocks can also provide a space-saving solution to control cabinet applications in industrial automation and in machine building. Separable terminal blocks – which clamp the wires with a screw connection – are particularly useful for this purpose. They allow for connections to be easily removed and reused if necessary.

Materials

Terminal blocks come in a variety of materials, each with its own characteristics and advantages. Plastic terminal blocks are simple to use and provide a reliable connection for most low-power applications. Metal terminal blocks are more suitable for high-power applications and offer higher levels of durability.

Working Principle

Terminal blocks are similar to screw terminals and have a terminal strip for each wire. This strip is then electrically connected to a terminal pin. When the screw terminal is tightened, the strip and pin come into contact and electrical current flows. When two terminal blocks are connected together, a conductor bar is used to ensure electrical continuity between them. The conductor bar has two busbars with insulated metal contact strips, which are separated by an insulating material called a dielectric. The dielectric acts as a barrier between the two busbars, preventing the current from flowing from one to the other.

Design Considerations

There are several important considerations when designing terminal blocks. These include the current ratings, housing type, and wire connection type. The current rating will determine how much power can be transmitted through the terminal block. The housing type is important as it will determine how the terminal block is mounted. The wire connection type will determine how the wires are securely connected to the terminal block.

Conclusion

Terminal blocks, also known as barrier blocks, are devices that provide an effective solution to simplify and improve the wiring of equipment. In 2015, manufacturers began using advanced application fields and working methods for terminal blocks. These devices are suitable for use in both wire-to-wire and wire-to-board connections, and can also provide a space-saving solution to control cabinet applications in industrial automation and in machine building. Terminal blocks are typically made from plastic or metal, and the current rating, housing type, and wire connection type must be taken into consideration when designing.
