skruvterminaler

Skruvterminaler, also known as screw terminals or screw clamps, are a common type of electrical connector used to terminate wires. They consist of a metal screw that passes through a metal clamp or lug, with a threaded hole for the screw to engage. When a wire is inserted into the terminal and the screw is tightened, the screw presses down on the wire, creating a secure electrical connection. This method relies on direct metal-to-metal contact to conduct electricity.

These terminals are widely used in various applications due to their simplicity, reliability, and cost-effectiveness. They are frequently found in power supplies, circuit breakers, junction boxes, and electronic devices where a robust and easy-to-use connection is required. Skruvterminaler can accommodate different wire gauges, and some designs allow for multiple wires to be connected to a single terminal.

The installation process typically involves stripping a portion of the wire's insulation, inserting the exposed conductor into the terminal opening, and then tightening the screw with a screwdriver. Over-tightening can damage the wire or the terminal, while insufficient tightening can lead to a poor connection, arcing, or overheating. Different types of skruvterminaler exist, including those with captive screws that cannot be lost, and those designed for specific wire types such as solid or stranded conductors. Maintenance often involves periodic checks to ensure screws remain tight, especially in environments subject to vibration.
