Terminal Blocks - Barrier Blocks

Terminal blocks, also known as barrier blocks, are small, usually rectangular blocks used to connect two electrical circuits. They are typically composed of metal or plastic with evenly spaced electrical terminals for making secure connections. A barrier block, also known as a pluggable terminal block, allows the user to easily plug a cable connector into it to provide a secure electrically connection. They are typically used in industrial and commercial applications but can also be used in consumer electronics.

Terminal blocks are used in a variety of industrial, commercial and consumer applications. They are commonly used in the electronics industry for constructing prototype and low voltage circuits, as well as for components such as switches and relays. Terminal blocks can also be found in test and measurement equipment, industrial controls and related products.In a typical setup, a terminal block can contain multiple electrical connections. The voltage and wiring connections are then placed in the terminals, creating the electrical circuit. Typically, the connections are joined using a screw, a solder joint or a spade terminal connector. In some cases, the terminal block will also be used to connect wires to other boards or components, such as a printed circuit board or a relay.

When the wires are inserted into the terminal blocks, a barrier or insulation strip is placed on the terminals to stop any electrical cross-talk between circuits. This barrier strip provides greater safety and insulation than what a single conductor cable could offer, making terminal blocks an ideal solution for connecting circuits in high-voltage or high-current applications.In addition, terminal blocks enable users to configure numerous types of wiring schemes, such as wiring points, bridges, rings, grids, busses, switches, and terminal blocks stacks. These wiring modes can be readily changed and reconfigured as needed.Moreover, terminal blocks can also include LEDs and pilot lights that can indicate the on/off status of the circuit and whether or not it is energized. This is a valuable asset in troubleshooting applications.

Terminal blocks provide a secure and convenient connection among multiple electrical wires and devices. They are especially helpful in larger applications where traditional wires may be too bulky and difficult to work with. Due to their many design features and capabilities, terminal blocks have become a mainstay in various industrial, commercial and consumer applications.
