Screw terminals are electrical connectors that secure wires by tightening a screw onto the wire. This design ensures a reliable and stable connection, making them commonly used in various electrical applications, such as in circuit boards and power distribution systems. They are favored for their ease of use and ability to handle different wire sizes. These terminals typically consist of a metal screw and a metal plate or clamp. When the screw is tightened, it compresses the wire against the plate, creating a strong electrical connection. Screw terminals are often found in industrial equipment and home appliances due to their durability and effectiveness.
