Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks are a staple component found in a wide variety of industrial and commercial applications. Generally composed of a connector, pins, and other components, these blocks are essential where devices need to be connected together in an efficient and secure manner. Headers, plugs, and sockets are among the components used within terminal blocks and their working principles and respective fields of application are outlined in this article.

Headers

Headers (also referred to as female contacts) are the female part of a terminal block and are found on the device to which the wires are to be connected. Headers consist of a single piece of metal, usually copper-based, and have several spring-loaded pins. Wires are pushed into the header and connected securely by the spring-loaded pins. The pins provide both electrical and physical connections and ensure that the wires remain securely connected even when subjected to significant vibration or force. The most common application for header terminal blocks is connecting industrial equipment to supply power or for data communication. These lengths may be long or short and generally require the use of intermediate connectors (e.g. plugs and sockets) for making secure connections which will in turn require headers.

Plugs and Sockets

Plugs are usually the secondary part of a terminal block, serving as the connector. Plugs consist of a male part with several pins which are designed to mate with the female header. The number of pins in the plug depends on the specific application. Plugs also feature either a spring loaded mechanism to secure the wire or a v-shaped retainer which helps secure the connection. These pins are usually copper-based and are designed to withstand the high levels of current and force which come with many industrial and commercial applications. Sockets are the same as plugs in that they feature a set of pins. However, in this case the pins are not spring-loaded. Rather, the wires are pushed directly into the socket and the connection is secured by an external pressure applied onto the pins. Sockets are usually found in applications where long lengths of cables need to be connected with minimal stress on the wires.

Conclusion

Headers, plugs, and sockets form vital components found in terminal blocks. Headers provide a female connection point to which wires can be securely attached. Plugs are typically the connecting piece between two terminal blocks and provide a secure male connection. Finally, sockets provide a secure connection between two wires with external pressure applied to the pins. These components are essential in the building of terminal blocks and finding their applications in industrial and commercial applications.
