Introduction to Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks are well-engineered connecting systems designed for making secure connections between cables, printed circuit boards (PCBs) and sensors. They are most commonly found in electrical and electronics applications such as industrial machines and automation systems.

Terminal blocks fall into two categories: headers, plugs and sockets. These categories can be further subdivided into specialty use models. Each of these are designed with specific functions in mind.

Terminal Block Headers

Headers are wire termination blocks commonly found in the bridge sections of a PCB. They connects layer-to-layer, layer-to-ground and, most importantly, layer-to-external wires.. They are made up of a main body with a mounted sockel on top for wire insertion. They provide the user with an alternative to manual soldering as they make wire mounting quicker and easier.

Terminal block headers utilize a specialized latching system which allows for effortless cable exchange. Take PCB headers for example, these electrical plugs feature a push-in connection interface which eliminates the need to use any kind of tool for wire insertion.

Terminal Block Plugs and Sockets

Plugs and sockets are designed to transfer signals or power between two circuits. The two main types are board-to-board plugs and sockets and board-to-cable plugs and sockets.

Board-to-board plugs and sockets are the most common types. They connect two circuits running in parallel. When connected, the feed-through is carried to the other board via a channel. They are typically made from metals like zinc and offer reliable connection for signal and power transmission.

Board-to-cable plugs and sockets plug into boards and into other machine equipment for a secure connection. They provide a super-low area of connection and enable mechanical stress relief for wires. They are usually interchangeable with standard plugs and sockets found in the market, meaning they can plug into other models of plugs and sockets.
