Introduction to Terminal Blocks – Headers, Plugs and Sockets

Terminal blocks also known as headers, plugs, and sockets, are electrical components used to join two wires together. They are used extensively within audio, video, automotive, and industrial applications where the need arises to join two electrical signals. Depending on the application, there are a variety of designs differing in size and shape.

Types Of Terminal Blocks

Crimp Terminals:

Crimp terminals are the most commonly used terminal block which is composed of a terminal block and a connector (or pin). The connector is often made of a simple metal strip, coated with a conductive coating. When the terminals are crimped, the connector makes direct contact with the wire, providing the required electrical connection.

Spade Terminals:

Spade terminals are similar to the crimp terminals, but are made of a metal or plastic strip with two slots. They are easier to install than the crimp terminals since they require no crimping and have an increased flexibility. The spade terminals are normally used with 12- or 24-volt systems and are designed to keep the two wires only partially connected in order to reduce the risk of a short circuit.

Blade Terminals:

Blade terminals are also known as flat blade terminals. They are the simplest type of terminal block and are generally used with AC/DC power components. The blade terminal consists of a flat metal plate with one side slightly bent. When the blade terminal is inserted into the electrical device, the bent end makes contact with the two wires and provides the necessary connection.

Barrier-strip Terminals:

Barrier-strip terminals are the most advanced and versatile type of terminal block. They are usually a strip of plastic or metal with multiple slots where wires can be inserted. They provide a secure connection and are widely used in high power applications such as aerospace and automotive applications.

Application of Terminal Blocks

Terminal blocks are designed to be easy to install, durable, and provide a reliable connection for any type of electrical application. They are especially useful in applications requiring multiple wires to be connected, such as in automotive, audio, and video equipment. Terminal blocks are also popular for applications that involve the use of a 12- or 24-volt system, providing flexibility and reducing the risk of a short circuit.

Working Principle of Terminal Blocks

Terminal blocks provide a secure connection between two wires for any type of application. Depending on the type of terminal block used, the electrical connection is made through crimping, using a metal strip with a conductive coating, or through inserting a flat metal plate into the device. The principle for each type of terminal block is the same: the electrical current is directed to the required location, providing the connection needed for the equipment.

Conclusion

Terminal blocks, also known as headers, plugs, and sockets, are used in many types of electrical applications for joining two wires together. They are available in a variety of styles, depending on the type of application they are being used for. The most commonly used terminal blocks are the crimp terminals, spade terminals, blade terminals, and barrier-strip terminals. Depending on the type of terminal block used, the electrical connection will be completed through crimping, inserting a flat metal plate, or using a metal strip with a conductive coating.
