Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks - headers, plugs, and sockets are electrical connectors which are used in various applications as means of connecting two, three, or more electrical circuits. They are designed to act as a reliability point for applications with limited space need, as they can frequently be found in small electrical enclosures which need to be kept completely sealed. They allow the user to make temporary connections that can easily be reconfigured or removed for troubleshooting or maintenance.

Application Field

Terminal blocks - headers, plugs and sockets, are commonly used to safely connect low-voltage and current, control and signal circuits. Terminal blocks come in a range of sizes and configurations with different voltage and current ratings for specific applications. Other than their use in industrial control systems, they are also used in building automation, motor controls, lighting, uninterruptible power supplies, as well as where greater insulation between conductivity is required.

Terminal blocks are occasionally used to connect multiple wires to one connection point to group wires together, for example to attach many wires used for motor connections in a junction box. Because of their common usage in industrial control systems for attaching multiple wires to a control device, they have become a universal tool for electricians and engineers. When using terminal blocks - headers, plugs and sockets, the key factor is to make sure they can handle the voltage and current of the work being done.

Working Principle

Terminal blocks - headers, plugs and sockets, provide secure, space-efficient connections without the use of tools. The terminals are connected in one wire at each end of the connectors and are typically color coded, intended to match the type of wire connections. The ends of the terminals are spring loaded, and the insertion of the wire forces the pin open to engage the conductive core, while the insulated outer shell closes around the hole to create an electrical connection. The two spring-loaded parts allow for a removable connection when needed.

The current flows from the plug when connected with the socket, thus creating an electrical network. This design allows easy debugging and maintenance, by providing flexibility when troubleshooting connections, or for reconfiguration of the network.

Terminal blocks - headers, plugs and sockets, provide strong connections and better insulations to reduce the chances of short-circuiting. Wires connected to the terminals are flattened and held in place with the help of special crimping tools, which are used to apply pressure to the end of the wire and ensure a firm connection. The connections have a safety rating, which is pre-defined depending on the voltage.
