liitäntäruuvi

A liitäntäruuvi, often translated as connection screw or terminal screw, is a type of fastener used primarily in electrical and electronic applications. Its main function is to provide a secure point for connecting electrical conductors, such as wires, to a circuit or device. These screws typically feature a threaded shaft that is inserted into a corresponding threaded hole or nut.

The head of a liitäntäruuvi is designed to accommodate a tool for tightening, commonly a flathead or Phillips screwdriver. Some variations may have a slotted head with a wide, flat slot for ease of use with a flathead screwdriver. The design often includes a washer or a flanged head to distribute pressure and prevent damage to the conductor or the connection point.

Liitäntäruuvit are manufactured from various materials, including brass, steel, and plated metals, chosen for their conductivity, strength, and resistance to corrosion. They are found in a wide array of devices, from simple household appliances and power strips to more complex industrial machinery and electrical panels. The reliability of the electrical connection is paramount in these applications, and the liitäntäruuvi plays a crucial role in ensuring this. Proper tightening of the liitäntäruuvi is essential to prevent loose connections, which can lead to increased resistance, overheating, and potential failure of the electrical system.
