ruuviliittimet

Ruuviliittimet, often referred to as screw terminals or screw connectors, are a common type of electrical connector used to join wires. They are designed to secure electrical conductors, typically wires, by using a screw to clamp down on the conductor and hold it in place. This creates a reliable electrical connection.

The basic structure of a ruuviliitin involves a metal conductive body with threaded holes. A screw passes through a portion of this body, and when tightened, it presses the inserted wire against the conductive part of the connector. This mechanical pressure ensures good electrical contact. They are widely used in a variety of applications, from household electrical installations to industrial equipment and electronic devices.

Ruuviliittimet are advantageous for their simplicity, low cost, and ease of use. They do not require specialized tools for installation, often just a screwdriver. Different types exist, including single-wire terminals, multi-wire terminals where multiple wires can be connected to a single point, and terminals with integrated strain relief to prevent wires from being pulled loose. The size and material of the ruuviliitin are chosen based on the current and voltage requirements of the application, as well as the environmental conditions. They offer a secure mechanical connection that is also electrically conductive.
