Terminal Blocks - Barrier Blocks

0382101504 Application Field and Working Principle

Located in the electrical industry, Terminal Blocks - Barrier/clips or Bridge Blocks provide a cost-effective and secure link between electrical components on a circuit board. A Terminal Block can be described as a connecting block that is designed to help organize your circuit board layout by providing numerous options regarding current and voltage rating, wiring options and mounting type.

Usable in various applications, these devices are designed to allow good electrical contact between two or more metal strips, wires, or cable lugs. They also provide a low resistance for electrical circuit connections, and also help to protect against electrical shock, eliminate the possibility of electric sparks, electrical short circuits, and ensure overall system safety.

Typically, Terminal Blocks - Barrier Blocks hold an internal pressure contact, two electrical contacts, and a spring-loaded shifter for multiple connection and direction. A slide switch connects internal pins with others on the same block by pressing down, essentially making it a more user-friendly and less time-consuming means to create connections. The used pressure contact is usually made of resistive material (such as copper, brass, zinc, or aluminum) that is already pre-mounted on an insulated core, and the insulated core is usually made of plastic, fiberglass, or rubber.

Apart from the aforementioned features, Terminal Blocks - Barrier Blocks are also capable of accepting various types of wiring such as ferrules, fork or stud type screws, hook and loop wires, and so on. Furthermore, these blocks feature plugs that are keyed for the future so that wire pairs are easy to clearly identify, and this further adds to its user-friendly interface.

As mentioned earlier, the primary function of Terminal Blocks - Barrier Block is to allow current to flow from one wire to the other, and it does so by pressing down on the contacts while separating the two electrical systems when exposed to an external shock. The blocks are also available in a variety of shapes, sizes, and designs, which makes it possible to create a large number of applications.

Some of the most common applications for Terminal Blocks - Barrier Blocks include battery chargers, industrial and consumer electronics, medical equipment, vending machines, lighting controls, robotic controls, process control equipment, and military components. Owing to their versatility and wide range of applications, these blocks are widely used in various industries.

The advantages of using Terminal Blocks - Barrier Block include their ability to save space on board, maximum mechanical and electrical reliability, compatibility with a wide variety of wires and connectors, easy installation and maintenance, and low thermal resistance, among others.
