Terminal Blocks - Barrier Blocks: Application Field and Working Principle

Terminal blocks offer high quality information exchange and power distribution through multiple electrical connections. Barrier blocks, more specifically, are widely used in a number of electronic and industrial applications as terminal blocks specifically designed for terminal protection. As the name suggests, these terminal blocks have a “barrier” which electrically isolates multiple terminals. This offers an efficient and cost effective solution to building and protecting terminal blocks.

Barrier blocks are designed to work with two distinct terminals separated by an electrical insulating barrier. Each terminal is connected by a single copper contact and the terminals are placed on opposite sides of the insulating barrier. This design offers greater separation between the connections and also a higher level of protection from electrical hazards. Linked together, multiple barrier blocks can provide one reliable point of contact for the entire system.

Barrier blocks are commonly used in a wide range of applications, including motor control circuits, robotics, lightening systems, wiring harness assemblies, and any other electrical circuits. Depending on the specific application, the terminal block can be composed of varying materials such as copper alloys, aluminum alloys, phosphor bronze, etc. Barrier blocks are designed for a variety of voltages, ranging from AC or DC voltage applications, as well as for both commercial and industrial applications.

Barrier blocks can be further sub-classified based on their intended purpose as well as their design and measure features. As such, there are several types of terminal blocks available, such as PCB terminal blocks, block-to-block cables, terminal-end board blocks, and various feeds and posts. These shapes and sizes are not only tailored to the desired application and are made to fit with the power supply, but are also designed to minimize contact resistance, ensuring quality performance and durability.

The working principle of barrier blocks is quite simple. The terminal blocks act as an interface between the equipment and circuit. They provide a secure connection point where electrical connections can be made without the risk of arcing or other undesirable results. This allows for the efficient transfer of electricity from the source power supply, typically through a power supply or distribution panel, to the terminal blocks and then ultimately to the equipment. The design of the terminal blocks ensures that the connections remain securely linked and that the electrical connections remain safe.

In conclusion, barrier blocks are a simple yet efficient form of terminal blocks specifically designed for terminal protection. These terminal blocks are highly dependable and energy-saving, making them suitable for a variety of applications, from general electronic and industrial applications to motor control circuits, wiring harness assemblies, and lightening systems. Barrier blocks are composed of different materials depending on the application and offer a number of shape, size, and voltage options. The working principle of these terminal blocks involves providing an efficient connection between the power supply and the equipment. This type of terminal block is ideal for ensuring a secure and reliable connection.
