Ruuviliittimillä

Ruuviliittimillä, often translated as screw terminals or screw connectors, are a common type of electrical connector used to terminate wires. They provide a secure and reliable method for joining electrical conductors. The basic principle involves inserting a stripped wire into an opening and then tightening a screw. This screw presses down on the wire, creating a mechanical and electrical connection.

These connectors are widely used in various applications, including household wiring, industrial control panels, power supplies, and electronic devices. Their simplicity, affordability, and ease of use make them a popular choice for many electrical installations. Ruuviliittimillä can accommodate a range of wire gauges, from fine wires to thicker cables, depending on the size and design of the terminal.

There are several variations of screw terminals. Some are designed for single wires, while others can accept multiple wires. Terminal blocks, a common form of ruuviliittimillä, consist of a series of individual terminals mounted on an insulating base. This allows for organized and safe connections within a larger electrical system. The materials used for screw terminals typically include conductive metals like brass or copper for the electrical contact and insulating plastics for the housing. Proper tightening of the screw is crucial to ensure a good electrical connection and to prevent the wire from loosening over time, which could lead to intermittent connections or overheating.
