Terminal blocks are electrical components that quickly connect multiple wires together in an efficient and space-saving manner. This type of terminal block, the wire-to-board variety, is employed for connecting both electrical and electronic equipment, including power supplies, motor drives, relays and semiconductor packages. By fastening its wires to board-mounted terminals, the technician is able to reduce a potentially complex web of signal wires and connectors down to a small number of connections.

Wire-to-board terminal blocks are available in a variety of different styles and designs, including coaxial, double-decker, and feed-through blocks. Coaxial blocks (sometimes called RF blocks) are designed to securely terminate coaxial cables, such as those used in antenna systems. Double-decker blocks are tall enough to accommodate two different wire types or sizes in two separate rows, while feed-through blocks feature two mating layers allowing the conductor carrying current in one direction to be independently connected to another conductor. The terms “device” and “power” blocks refer to blocks that have integrated relays, switches, and other current-carrying devices, allowing for additional flexibility in the power and/or control circuitry. This type of terminal block is often used in the industrial segment.

The various types of wire-to-board terminal blocks are designed to accept a variety of wire sizes and insulation types, including solid or stranded copper, aluminum, or even fine-stranded auditory. The materials used in the terminal blocks also vary, but the objective is always the same: a secure, temperature-resistant connection. These blocks generally utilize a screw-clamp mechanism, which is tightened using a torque screwdriver or similar device, with no additional adhesives or fixers required. The intrinsic design of these terminal blocks prevents any inconsistencies in the connection from developing over time.

The overall size of wire-to-board terminal blocks depends on the number of wire connections needed. Generally, standard sizes range from a two-circuit configuration up to a thirty-two circuit block. When connected in series, providing additional current-carrying capability over a single terminal block, even larger configurations can be created. Operating temperatures for these blocks can range from -40°C almost up to 200°C, depending on the materials used in the component.

Wire-to-board terminal blocks offer the technician or engineer a reliable, efficient, and lightweight solution for connection needs. With the variety of sizes, shapes, and styles available, these components can be employed in a wide range of 1697150000 application fields.
