Terminal Blocks - Barrier Blocks

3-1546561-3 terminal block, more commonly known as Barrier Blocks, are used in various electronic devices where the need to bring out signals to a connector arises. They come in several sizes, styles, and contact configurations. They are used in industrial automation, military, medical, HVAC, telecom products, and other applications.

Barrier Blocks are commonly linked together and used in a variety of wiring configurations for maximum convenience. Depending on the application, barrier blocks may be installed alone or in conjunction with control boxes, power box assemblies, or junction boxes.

Working Principle

Barrier blocks are designed to provide electrical connections between a given set of two terminals. They effectively connect isolated circuits while preventing leakage current between the two points. This is achieved by incorporating a “barrier” between the two points of contact. This barrier is typically made of insulating material such as plastic or paper.

Barrier blocks typically have two metal contact points, typically made of copper and silver alloys. These are mounted onto the barrier itself to form a contact bridge. The two contacts, when pressed together, form a circuit when electricity is applied to them.

Barrier blocks also feature a “slot” at one end, which provides an increased amount of surface area for the contact points. This increased area helps to provide a more secure connection.

The contact bridge between two points is usually covered in an insulation material, such as plastic or rubber, to prevent any accidental contact with other components. This insulation also serves to protect the metal contacts from corrosion and other environmental damage.

In addition to providing electrical connections, barrier blocks are also used to provide mechanical support for various components. This is achieved by the use of “clips” or “washers”, which are attached to the barrier itself and hold the components in place.

Barrier blocks are designed for easy installation and removal. This is achieved through the use of mounting tabs, which are connected to the barrier itself. The tabs enable the user to attach or detach the barrier block to other components quickly and easily.

In addition to providing electrical connections, barrier blocks can also be used as a form of insulation. This is achieved by providing a foam or rubber coating to the metal contact points. This helps to protect the contacts from environmental damage as well as provide an effective heat sink. This also helps to ensure that electrical signals are accurately transmitted between two points.

Barrier blocks are an essential component in a wide range of electronic devices. They are often used to provide electrical connections in industrial automation, military, medical, HVAC, and telecom products. They feature a robust design that is able to withstand a variety of environmental conditions and ensure reliable connectivity and insulation.
