Terminals - Turret Connectors

Turret connectors are a form of terminal block or terminal strip, commonly used in power distributed systems such as mains power supply, industrial lighting, railway systems, and automation systems.

A turret connector includes multiple wire leads or connections that are connected to a single base connection, and the connection sockets are formed into a turret shape. Their shape makes them particularly suitable for high power applications such as mains power supply, since the turret shape prevents pins from connecting with each other and helps to maintain a reliable and robust connection.

Each turret connection includes a terminal connection at one end, often referred to as the face or head, and a screw connection at the other end, commonly called the body or tail. The body connection is typically used to connect the system ground or earth wire, while the face connection is used to connect to the power supply. The connection between the body and the face is referred to as the terminal block or terminal strip.

There are a few different types of turret connectors, such as closed-end, open-end, and shrouded types. Closed-end turret connectors are used when the application requires a more robust connection between the terminal and the power source, as the connection between the body and the face is completely metal-to-metal, creating a connection that is more resistant to dust and vibration. Open-end turret connectors are often used in low power applications where vibration is not a concern, and the wire connections are exposed.

Shrouded turret connectors offer the same level of protection as closed-end connectors, but with added protection against dust and vibration. The shroud is also used to protect the connection from moisture and other contaminants, making them ideal for high-power and high-reliability applications.

The working principle of a turret connector is relatively simple. When the wire is connected to the face, current will flow from the power source to the face connection, and the screw connection will form a connection to the system ground or earth wire, creating a continuous electrical circuit. This allows for a reliable and stable connection between the power source and the load, right from the source.

Today, turret connectors are used in a wide range of applications, such as electrical distribution systems in both commercial and industrial settings, lighting systems, aircraft maintenance and repair, and automotive applications.

Turret connectors offer reliable connections, superior durability, and the ability to protect against dust and vibration, making them ideal for high power and high reliability applications. They are also cost-effective and easy to install, making them a popular choice among industrial and commercial professionals.
