Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks are a type of electrical connector used for electrical connections, interfacing and grounding. Connections are generally made with screws and tabs, and are commonly used in industrial and commercial applications, computers and aviation. The main types of terminal blocks are header, plug and socket, each with their own individual characteristics and design features.

What is a Header Terminal Block?

Header terminals are wide, narrow strips, sometimes referred to as “strip header.” These headers have multiple-pole or single-pole function and are used to provide connections between circuits. Header terminal blocks provide solder points for fastening wires and other conductors to the terminal block. Header terminals are generally offered in single- or multi-row configurations. The single-row header has two parallel indentations at either end that are used to connect adjacent terminal blocks together. Multi-row headers feature a third indentation that is used to join multiple rows together. Common terminal block options include pre-assembled, punch-down and thermocouple.

What is a Plug Terminal Block?

A plug terminal block is a pluggable terminal block made up of a molded plastic housing, two grooved screws and two contacts. This type of terminal block is designed to provide connection for both circuit protection and power distribution. Connections are made by inserting the two contacts into a mating female connector until they click into place. The two grooved screws are then tightened to ensure that the connections remain secure. Plug terminal blocks are commonly used in the automotive, aerospace and electrical industries.

What is a Socket Terminal Block?

Socket terminal blocks are also known as "blocking type" or "free type" terminal blocks. Similar to the header terminal blocks, these provide connections between two circuits and have a flexible design to accommodate differing wiring configurations. With socket terminal blocks, no screws are required as each contact is inserted into the receptacle and then locked in place. This connection is made using a male and female contact allowing the user to connect and disconnect quickly and easily.

Terminal blocks are commonly used in industrial and commercial applications such as aerospace, automotive and electrical production. These terminal blocks are designed to provide connections between two or multiple circuits, often in a controlled and compact manner. The working principle of each type of terminal block will vary depending on the design and material; however, each type of terminal block will provide a secure connection for the electrical components. Header terminals typically involve screwing the contact into place, while plug and socket terminal blocks require an insertion and locking mechanism to ensure a secure connection.

Terminal blocks provide an effective solution for the fast and secure connection of two or multiple circuits. These blocks offer a convenient way to manage and organize electrical connections, making them an ideal choice for industrial and commercial applications. With the range of different designs and options available, it is easy to find the perfect terminal block for the job.
