Terminal strips and turret boards are two types of electronic components used to make electrical connections between various item such as wires, relays, and other devices. They are often used in applications such as military, industrial, commercial, and consumer electronic products.

Terminal Strips

Terminal strips are used to connect wires and devices or, to provide support and strain relief for wires. They are typically made from metal, such as brass, and they come in a variety of shapes, sizes, and styles. The two most common types are barrier strips and pin strips. Barrier strips are two-piece and have scissor action contacts inside that open and close to make a connection. Pin strips are single-piece and feature spring contacts that depress to make a connection.

Terminal strips are widely used in various applications, such as communication systems, audio gear, industrial control, and medical systems, among others. The primary benefit of using terminal strips is that they can provide a secure, reliable connection, which can be easily disassembled and re-assembled for maintenance and repair.

Working Principle

Terminal strips provide a means for a secure and efficient connection between two or more items. They typically work by clamping down or depressing two contact points so that the electricity can flow from one object to another. When the contacts are open, the electricity cannot flow. Depending on the type of terminal strip, the contact points can be accessed via screws, levers, or spring contacts.

In some cases, terminal strips also provide the option to terminate wires by inserting them into the contact points and tightening down a screw. This is called a “solderless connection” and provides a secure termination for the wires. It is important to note that these connections are not as permanent as soldered connections.

Turret Boards

Turret boards are an extended form of terminal strips. They are also used for connecting wires and devices, but they are more specialized than terminal strips. Turret boards are typically constructed from metal and plastic, and come in a variety of shapes, sizes, and styles.

The primary benefit of a turret board is that it can provide a much faster, more efficient connection than a terminal strip. The contact points can be quickly accessed and manipulated, making it easy to add or remove connections. This makes them ideal for applications that require frequent wiring changes.

Working Principle

Turret boards use contact points that are mechanically operated by a handle. The handle can be moved up and down to clamp down on two contact points which creates a connection. This allows for an incredibly fast and efficient connection that is easy to modify.

In addition to providing a faster and more efficient connection than a terminal strip, turret boards can also offer additional features. These include reset and polarity screws, grounding posts, and other features that can provide additional safety and protection from electrical shocks.

In conclusion, terminal strips and turret boards are two different types of electronic components that can be used to make electrical connections. Terminal strips are designed to provide a secure, reliable connection and are commonly used in various applications such as military, industrial, commercial, and consumer electronic products. Turret boards are an extended form of terminal strips and provide a faster, more efficient connection. They are suitable for applications that require frequent wiring changes.
