Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks, headers, plugs, and sockets, are physical connectors that facilitate the connection of multiple devices in the electrical, computing, and telecommunications industries. From the simplest form such as a stripped plastic or metal screw down connector, to fully integrated electronics in the form of a motherboard receptacle, these are vital components in the wiring systems of every branch of modern industry.

Types of Terminal Blocks

Terminal blocks can generally be divided into two broad categories: fixed and removable. Fixed terminal blocks, such as those found in consumer electronics, are permanently affixed to the conductor with either a screw terminal, fuse, solder, or other hardware component. Removable terminal blocks, such as DIN-rail mounted terminal blocks, have an integrated wire clamp system that allows the user to easily disconnect and reconnect the conductor from the terminal block.

Application Field

Terminal blocks are used in a variety of industrial applications ranging from small hobby electronic projects to large-scale commercial wiring projects. From simple two-wire projects to complex wiring schemes, terminal blocks provide a reliable connection platform for both electrical and communication wiring.In larger-scale projects, terminal blocks are used to create massive electrical networks in factories, airports, power plants, and educational institutions. In such wiring configurations, terminal blocks are typically grouped to form panels of several inter-connected blocks, allowing for centralized control and streamlined changeovers for more efficient maintenance.

Working Principle

Terminal blocks are wired directly into or onto a device. The device\'s input and output terminals are wired or soldered into the block. When the terminals are crimped onto the block, a secure connection is made that facilitates an electrical connection between the device and the wiring. The wiring then exits the block and is routed and connected to an adjacent terminal or device connection, creating an electrical loop that runs from one connection to the next. In more basic applications, wire wraps are commonly used to connect wire ends onto the terminal blocks. Wire wraps are a type of wire-stripping tool which encourage electrical insulation by removing the corrosion and oxidation caused by exposure to air or other elements.

Advantage

Terminal blocks are extremely useful for making both low- and high-voltage connections. They provide mechanical support for electrical wiring layouts and are capable of handling significant amounts of power transfer. Furthermore, the connection process is simple and does not require the use of complex tools or machines. Terminal blocks are suitable for nearly any application where reliable electrical connections are needed. They are economical, easy to install, and increasingly available in a variety of sizes and styles to suit any wiring needs. By utilizing the proper type and quantity of terminal blocks, a secure and reliable wiring system can be made.
