Terminal Blocks - Barrier Blocks: 325018-01-0 Application Field and Working Principle

Barrier blocks are a type of terminal block that are designed for quick and easy electrical connection in a variety of applications. Barrier blocks allow for a simple yet versatile method of wiring up control panels, motor controllers, and industrial machines. They consist of a plastic housing with metal strips attached inside and a series of male and female terminal pins. The metal strips provide the electrical connection to the terminal pins.

Barrier blocks can be used to connect various types of wires together to provide a safe and secure connection. This makes them ideal for wiring systems in industrial environments, especially in the automotive and aerospace fields. They can also be used in homes and other places where a secure connection is desired. The type of connections that can be made with barrier blocks depend on the type of latch they feature and the type of wire used.

Barrier Block Application Field

The primary application of barrier blocks would involve the connection of various wires to form an electrical circuit. For example, barrier blocks could be used to connect a motor\'s power and ground wires, or to connect various control devices within a system, such as a temperature controller, driver and amplifier. Also, barrier blocks are used to span short distances between two points of a circuit, allowing for a secure connection.

These terminal blocks are also used in applications that require multiple circuits, as they provide an easy way to connect and disconnect various types of wires, without causing any damage. Furthermore, they are often used in the automotive industry, where they typically form part of an engine wiring harness. Other common applications include robotics, lighting controls, power supplies, and switchgear.

Barrier Block Working Principle

Barrier blocks work by connecting two or more electrical wires together. The terminal pins are attached to the block housing and the metal strips inside make the connection to the voltage source. The primary purpose of the barrier blocks is to provide a safe and secure connection without needing additional wires.

To make a connection, one or more wires are inserted into the terminal pins and the terminal is then pushed down into the housing. This pushes the metal strip inside the barrier block against the wire, forming an electrical connection between the two. The wire is then secured to the block by clamping the metal strip down, ensuring a secure connection.

The barrier blocks can also be daisy-chained together, allowing multiple wires to be connected together in a single block. This is achieved by inserting the pins of one wire into the pins of the adjacent block, creating an electrical connection between the two. This can be particularly useful in robot applications, as it allows for multiple functions to be controlled from a single point.

In summary, barrier blocks are a useful and versatile type of terminal blocks that can be used in a variety of electrical connections. Their primary application is to connect different types of wires together securely, without the need for additional wiring. They are typically used to span short distances between two points in a circuit, and are often used in industrial and automotive wiring harnesses. Additionally, they can be daisy-chained together to provide multiple connections in a single block.
