Terminal Blocks - Wire to Board

Terminal block can be classified as a type of electrical connector, also described as connector blocks or terminal boards, which attach the wires from electrical equipment to the power source. Various types of terminal blocks are available including panel mount, barrier, screw, and pluggable type. In the past, traditional brass blocks were used, but nowadays plastic is more often used because of its insulating properties and temperature resistance.

Terminal blocks are mainly used in market segments such as industrial automation, power distribution, railway signaling, and broadcast. With common features such as mating screws, locking covers, and connection points on both sides, terminal blocks are available in a range of sizes. They are designed to make connections between different size and type of wires. Each terminal can support up to several hundred amps of power and are rated in temperature classes according to the Underwriter Laboratories rating system.

Terminal blocks reduce the work time of making connections when dealing with great amount of single wires inputting into an electrical system. They also provide safe, reliable, and efficient connections. Some benefits of using terminal blocks include providing a secure electrical connection, providing easy access for testing and maintenance, and providing insulation from short circuits.

There are several types of terminal blocks which are categorized based on the connection technology. The most common terminal block datasheet categories are spring clamp terminal blocks and screw termination blocks. The spring clamp terminal blocks accept individual wire, while the screw termination blocks usually feature an insulated adapter with a large barrier strip.

For screw terminal blocks, each wire is connected to a separate terminal. This type of terminal block is popular due to its high reliability and performance. When connections are made the screw tightening action ensures that a tight connection is maintained. Screw terminal blocks are available with a range of screw sizes and thread types, depending on the application.

The proper selection and use of terminal blocks is critical for engineer who design a production line or electric system. The proper selection and use of terminal blocks insure that the wires can carry the needed electrical current and voltage for a given operation. Furthermore, the terminal block should be managed in order to prevent contact corrosion and reduce the risk of short-circuit.

In recent years terminal blocks have been improved by using various advances in technology, for example higher temperature plastics, molded plastic covers, and improved insulation materials. These factors make modern terminal blocks more suitable for use in demanding application in which a more robust product is needed.

Overall, terminal blocks make it possible to connect electrical wires quickly, easily, safely, and reliably, without the use of complex tools or special skills. They are simple to install with standard tools and require minimal maintenance.
