Terminal Blocks - Barrier Blocks

Barrier blocks, also known as terminal blocks, are electrical wiring components used for joining electrical wires together. Barrier blocks are an essential part of building and connecting electrical systems and of avoiding accidental electrical contact. They are also used as a means of providing protection against electric shock.

Barrier blocks are generally made of plastic or aluminium with contacts made of either brass, copper or silver. They come in a variety of shapes and sizes and can be used for either industrial or domestic applications. Barrier blocks are commonly used in automotive industry, medical devices, audio/video equipment, lighting systems and computers.

Barrier blocks are essentially designed to provide an effective means of safely joining together two or more electrical wires without the need for soldering or other sort of physical connection. The contact surface on each terminal block is designed to make contact with the wire conductor inside the terminal block, thus forming a permanent electrical connection. This design allows for a simple and quick electrical connection within a system. This is also why barrier blocks are so widely used in almost any type of electrical or electronic circuitry.

Barrier blocks usually consist of two metal blocks, each with separate contacts. One of the blocks holds the electrical wire to be connected, while the other block holds the opposite end of the wire. The two blocks are held together by a screw, and the electrical connection is made when the screws are tightened. Typically, there are two sets of contact points in the blocks - one set for joining two or more wires together, and another set for connecting the wire to an external ground.

The working principle of barrier blocks is quite simple. When the screws are tightened, the wire is forced against the contact surface of the block, creating an electrical connection. This electrical connection can be permanent or it can be designed to freely come apart and reattach, depending on the specific application. The advantages of using barrier blocks are obvious - they are flexible, reliable and cost effective. Barrier blocks are also easy to install and maintain.

Barrier blocks are a safe and effective way to join wires together. They are a quick and efficient way to join two or more wires together in any kind of electrical or electronic circuitry. They are a cost effective solution for those seeking easy installation and flexible wiring options. They can also be used for permanent electrical connections, providing a secure, reliable connection. Barrier blocks are sure to be a reliable part of any electrical system.
