Terminal Blocks - Barrier Blocks

Terminal blocks, also known as barrier blocks, are electrical devices designed to make connecting and removing wires from a system safer and more efficient. They are usually mounted on a chassis and use plastic attachments to hold each individual wire within the voltage block. Terminal blocks can be used in a wide variety of applications, from simple home appliances to complex industrial electronics. In this article, we\'ll explore the types of terminal blocks available, their application fields, and their working principle.

There are three main types of terminal blocks for individual wire systems: barrier strips, spring blocks, and cloisonne blocks.

Barrier strips, also called screw-down blocks or insulated terminal strips, are the most common type of terminal block. They come in a variety of sizes and shapes and are used in many different applications. A barrier strip is essentially just a strip of non-conductive insulating material, like plastic or PVC, with loop plugs on the top and bottom. Each loop plug is then connected to a wire using screws or studs.

Spring blocks, also called springclips or press contacts, are designed for faster and easier wire connection and removal. Most spring blocks are made from non-corrosive steel and work with stranded or solid core conductors. They use a simple push-in connector design, so no tools are needed to make a connection. Spring blocks are generally used in applications that require quick and easy connection and disconnection of several wires.

Finally, there are cloisonne blocks, which are used for connecting high-voltage circuits. Cloisonnes are also made from non-conductive insulating materials and feature large, solid contacts that are inserted into metal contacts when making a connection. Cloisonnes are used primarily in high-voltage applications, such as power distribution, and provide a high level of insulation between the contacts.

Terminal blocks are used in a variety of applications, from consumer electronics and home electrical systems to power distribution and industrial electronics. In consumer electronics, terminal blocks make it easy to connect and disconnect wires from the main circuit board, allowing for quick and easy repair and replacement. In power distribution, terminal blocks allow for easy, safe interconnection between circuits, allowing for the easy transfer of power. Finally, in industrial electronics, terminal blocks are used for quick and simple wire connection and disconnection, allowing maintenance personnel to quickly repair and replace components.

Terminal blocks use a simple working principle to make connections. As mentioned earlier, most terminal blocks use a screw-down connection or a push-in connection style. With a screw-down connection style, conductive material, such as a wire or conductor, is inserted into the loop plugs and secured with a screw. The junction between the plug and the conductor is then insulated with a plastic boot or sleeve. In a push-in connection style, the conductor is simply inserted into the spring block and a metal contact carries the current to the conductor.

Terminal blocks provide a convenient and safe way to interconnect wires and cables in a wide variety of applications. They come in three main types: barrier strips, spring blocks, and cloisonne blocks, and can be used for consumer electronics, power distribution, and industrial electronics. Their working principle is simple and dependable, making them a popular choice for making electrical connections.
