Introduction to Terminal Blocks - Barrier Blocks
Terminal blocks – barrier blocks, also known as screw or plug terminal blocks, are a type of electrical connection device used to join two electrical wires together. They form a secure connection between two wires that is much more reliable than traditional soldering or crimping methods. Barrier blocks are blocks of metal or plastic that act as a bridge between two different points in an electrical circuit, allowing electricity to travel between them. They are connected via bolts, nuts, or screws. Typically, each block has two terminals – a male and female terminal – one at the top and one at the bottom. The male and female terminals are designed to snap together quickly and easily, allowing electricity to be passed along a wire connection.
Advantages of Terminal Blocks – Barrier Blocks
Barrier blocks offer several advantages over traditional wiring. One of the primary benefits is that they provide a stronger connection than soldering or crimping. This means that they are less likely to come loose or fail due to inferior connections. Additionally, barrier blocks are typically more reliable than solder connections because they require fewer steps in the wiring process. With solderless construction, installation of the wiring is much simpler and faster.
Another advantage of barrier blocks is that they provide a secure connection between two wires without the need to solder the wires together. This eliminates the need for soldering tools and associated equipment. In addition, most barrier blocks are designed to be removable from the circuits they are felted to, allowing circuits to be changed or reconfigured easily and quickly. This makes it easy to add, remove, or replace components in a circuit without having to disconnect and re-solder connections.
Uses of Terminal Blocks – Barrier Blocks
Terminal blocks – barrier blocks can be used for many different applications, including:
- Automation and control: Barrier blocks are often used in automation and control applications, such as motor speed control, where their ability to easily and quickly connect electrical circuits makes them invaluable.- Industrial applications: They are also commonly used in industrial applications, where reliable, secure connections are essential.- Electronics testing: Barrier blocks are used in testing electronic components, as a means of easily connecting test equipment.- Wire harnesses: Barrier blocks are also frequently used to provide secure connections for wire harnesses, where each wire is connected to the block separately.- Power distribution: Many barrier blocks are used in applications such as power distribution, where they are used to power multiple circuits with a single connection.Working Principles of The Terminal Blocks - Barrier Blocks
The function of the terminal blocks is simple but effective. A relatively simple mechanism is responsible for creating a reliable connection between two wires, which is applicable in a number of situations. A nut and bolt are used to connect the terminal block to a baseplate. The terminal blocks have a slotted insert that the wires are placed in. They also have a pair of terminal contacts, one male and one female. Once the wires are securely inserted into the insert and the terminal pair is pressed together, an electrical connection is formed.
In addition to providing a reliable electrical connection, the barrier blocks also provide some degree of protection against overloaded circuits. This is achieved by having the integrated screw-and-nut mechanism act as a fuse, meaning that if too much current is drawn through the connection, the nut and bolt will heat up and eventually melt, breaking the circuit and preventing damage to the equipment.Conclusion
Terminal blocks – barrier blocks are a reliable, easy-to-connect device used in a range of applications, from automation and control to power distribution. Their integrated screw-and-nut mechanism provides an electrical connection with excellent conductivity, as well as some degree of overload protection, making them an ideal choice for many applications.
