Terminals - Turret Connectors

Turret terminals, sometimes known as turret connectors, are set-screw terminals used to connect wires to printed circuit boards. These terminals are designed for use in high-performance electronic equipment, such as computers, block-and-tackle systems, and telecom switching centers. Turret terminals are made with standard threaded metal posts, allowing for the fastening of wires that are crimped onto the contact.

These terminals are useful for connecting multiple signals at a single point. For instance, if several signal lines must pass through an amplifier, a single turret terminal can be used instead of multiple, separate terminals. This reduces the time needed for installation as well as the chances of error.

Turret terminals are used in telecommunications, signal processing, and audio/video systems.In many cases, these types of terminals are used in high-density audio/video switchgear. Since wire-to-board connections are often needed in systems of this type, the turret terminals allow for a quick and efficient connection.

The working principle behind turret terminals is straightforward. In most cases, these terminals use a small set-screw to secure the wire to the contact post. The contact post and the screw are both physically insulated, preventing any possibility of shorting. Once the wire is in place, a nut is tightened onto the set-screw, completing the connection.

This is a much faster method of connecting wires than soldering, and has the advantage of being easily reversible. If the wire needs to be replaced, the terminal can be quickly unscrewed, and the wire can be disconnected and replaced with a new one. This is especially useful in cases where the wire is exposed to expansion and contraction due to changes in temperature or vibration.

Turret terminals are an important part of many industrial, electronic, and communications systems. They are highly reliable and require minimal installation time, making them the perfect choice for applications where quick, secure connections are needed.
