Screw terminals are electronic components composed of plated brass, allowing the wires or cables to make a connection directly among communicating devices, specifically making a connection with the printed circuit board that is made of a metal frame and a screw. This screw terminal is reliable and protective to printed circuit boards because of its utilization in mounting legs, which are inserted into holes and held with the printed circuit board, and soldered into position.
A pre-stripped wire is confined inside the head of a screw since this screw is tightened downward with the help of a screwdriver, allowing a strong and protective electrical connection between the wire and the metal frame. Some connectors are terminated by using these wires, which are spade or ring Terminals put forward over the screw.
Types of Screw Terminals
There are terminals available in a variety of body plating, right-angle or vertical mounting body orientations, and current ratings. To make screw identification and troubleshooting easier, certain screw terminals use colored screws.
What are the Benefits of Screw Terminals?
These terminals offer a wide range of benefits with a straightforward installation and are put into position. It can be carried out with hand tools.
- Can be used with solid, stranded, and pre-terminated wire.
- Ensure high-density wire connections to printed circuit boards.
- Kinked leg versions for extra retention on the printed circuit board.
- Cost-effective eliminates the necessity for a mating connector.
- When properly tightened, they offer an electrically strong and reliable connection.
- Can be reused in the industry, allowing for the replacement of wires or equipment.
Where is the Screw Terminal Used?
Printed circuit boards' terminals ensure electrical connection to lead signals and current that flow to and from equipment that has been embedded with an electrical device.
