Terminal Blocks - Headers, Plugs and Sockets, otherwise known as 1857993, are components used to connect two or more electrical wires or cables together. By using these, connection points can be easily broken down into individual tasks and feature a variety of methods to attach to each other. This makes them particularly useful in applications where components like cables and wires need to be installed and moved around easily.

Terminal blocks typically consist of two or more rigid plastics parts much like a kind of connector. These parts can either be connected using a screw connector or sometimes feature a soldered or crimped connection. Generally, there are three types of terminal blocks; Headers, Plugs and Sockets. In order to create a secure and reliable connection between two or more cables and/or wires, all three types must be used in conjunction with one another.

Headers are the main component of a terminal block system and are most commonly used for bench-top wiring. They are designed to take multiple plugs or sockets and usually feature a range of different connection points. Depending on the system in use, the header can accept either a directly connected plug, or a plug which needs to be secured using a screw connector. Many headers also offer additional features like a small terminal or bit to help prevent loosening of the connections.

Plugs are the components which are connected to the wires or cables. They are designed to securely contact the header either through a direct contact or by using a screw connector. The main advantage of using plugs is that they allow addition wiring points to be easily added to the system without needing to reconfigure the whole wiring setup. Plugs typically come in a variety of shapes and sizes, dependant on what type of header they are intended to connect with.

Sockets are designed to be installed on the end of a wire or cable, allowing it to then connect securely to a header or plug. There are two main types of socket, a standard size and a mini socket. Standard sockets are typically used when the wiring needs to be organized properly and the maximum amount of contact is required. Mini sockets are used in applications such as motors or in any application where space is limited.

1857993 application field and working principle are intrinsically linked with the three main elements of a terminal block system, headers, plugs and sockets. As a complete system, these three elements are designed to be used together in order to ensure a secure and reliable connection for electrical wiring. As such, 1857993 finds application in many industries, including industrial automation, automotive, instrumentation and computing.
