Large ring terminal connectors are commonly referred to as lugs. This terminology is widely used in electrical applications to describe connectors that are designed to be fastened to a bolt or a stud, ensuring a secure electrical connection. Lugs typically feature a circular opening that allows them to be attached to power distribution equipment, battery terminals, or other components in a circuit where reliable conductivity and strength are essential. In contrast, terminal blocks refer to a specific type of electrical connection point that houses multiple circuits in a single block, while fasteners are a broader category that includes items like screws and bolts used to hold components together. Clamps serve a different function, usually involving securing wires or cables in place rather than providing a direct electrical connection. This distinction helps clarify why lugs is the most appropriate term for large ring terminal connectors.
