Terminal Blocks - Barrier Blocks

Terminal blocks, also known as barrier blocks, are commonly used components in electrical and electronic circuits. They are generally used to make connections between multiple circuits, usually in order to provide insulation and protection. They are typically single-pole with their contacts split into two sections, each one accommodating either two wires or a terminal block connector.

The 1-1546968-6 model of terminal block is one example of a barrier block. This type of terminal block is specifically designed for low-voltage distribution, and is often used in power supply units and control systems.

Application Field

Terminal blocks are used in almost any type of system that requires a high degree of flexibility in terms of wiring. They are particularly common in industrial automation systems, where the terminals can be adjusted or replaced without disturbing any of the other components. They are also frequently used in industrial and commercial power distribution systems.

Terminal blocks are also used in many consumer electronics applications. Examples include computer motherboards, computer gaming consoles, and even automobile electrical systems. In these cases, the terminal blocks are typically used to make electrical connections between components.

Working Principle

The working principle behind a terminal block is fairly simple. When two or more terminals are inserted into the block, the contacts in the block make an electrical connection. This connection allows electricity to flow between the different terminals.

To ensure that the current does not escape from the block, the block is made up of two or more conductors, which act as an insulator. These conductors form a barrier between the terminals, preventing any current or voltage from escaping. This ensures that the current is routed to the correct destination and that the electricity remains safe.

To further improve safety, many terminal blocks are fitted with a fuse or circuit breaker. These safeguard the electronics in the circuit, while also making it possible to shut off the flow of electricity if necessary.
