Terminal Blocks - Wire to Board
Terminal blocks, also known as barrier strips, are a commonly used board level connection method for connecting wires to mounting equipment such as racks/cabinets/panels. Such terminals not only enable the assembly and maintenance of components in the electrical and electronic systems, but also carry the power and control signals from the main circuit board to the various parts in the system.
The terminals provide flexibility in the connection of wires, for example, the number of wires that are connected can vary and multiple layers of lines can be interconnected as it is easy to add or remove wires from terminal blocks. They are also quite robust and the same terminal can be used for multiple connections.
The two most common types of terminal blocks are wire-to-board and board-to-board. The former connects wires from an external source to the board-mounted equipment, and the latter connects two board-level components. Wire-to-board type are more commonly used. They come in various shapes and sizes and a variety of panel-mount materials.
The wire-to-board terminal blocks feature multiple spaces for accommodating various sizes and types of electrical wires. Each block typically has a series of holes called “wipe” that are used to accommodate different wire diameters, so as to achieve secure connections. Each hole also has a spring element inside to ensure stable and reliable connectivity.
The terminal blocks are designed in a variety of configurations such as the vertical access, vertical screwless, horizontal access, and horizontal screwless. These configurations can allow a wide range of wires including stranded, solid state, and flexible types. Each of them also comes with different levels of current carrying capacity and voltage rating, so it is important to select the right type according to the application requirements.
Wire-to-board terminal blocks can be used in various industrial, automotive, and consumer applications such as power supply, motor control, lighting, high voltage power distribution, and other automated devices. They can help to ensure a secure connection in circuits with higher power demand or with large number of components.
The working principle of wire-to-board terminal blocks can be simply explained as follows: A wire of specific diameter is fed from an external source through the hole in the terminal block, connections are securely tightened, and the spring element inside the terminal presses against the wire so as to create a good contact. This process is repeated with each wire for all the components in the system.
In summary, terminal blocks are designed to make physical and electrical connections between wires and a board-mounted equipment. Among the different types, the wire-to-board terminal blocks are most commonly used as they are easy to install and allow multiple wires to be securely connected in a single device.
