Terminal Blocks - Accessories

Terminal blocks are a type of vital electrical component typically found in a variety of settings, from industrial manufacturing applications to commercial wiring and electronic circuits. Accessories are available to connect them together and tie them into larger systems, ensuring they function correctly and are safe for use.

1970 Application Field

Originally introduced in 1970, terminal blocks have been used for a range of applications including electric motors, alarm systems, workbench testing equipment, high voltage power supplies, isolators, and robotic systems. Thanks to the variety of terminal blocks available, users can now link everything from electrical components from a variety of brands and product types while allowing sufficient electrical current to pass freely between them.

Industries that make use of terminal blocks and their accessories include but are not limited to marine, automotive, military, and marine equipment, industrial robotics, power generation/distribution, oil/gas refineries, and medical equipment at hospitals and other healthcare facilities.

Working Principle

The working principle of terminal blocks is relatively straightforward and relies on two main factors to create an electrical connection between components. The first factor is a small screw, which is used to securely fasten a terminal block in place. Second, a conductor in the form of either a flat wire or a threaded rod is used to transfer electricity between two components.

Terminal blocks are designed to allow only minimal contact points between the wire and the body of the unit, reducing the risk of wires overheating or shorting out. When using a threaded rod, the rod is inserted into an opening at the top side of the block and then the screws are tightened. The terminal blocks are then ready to be connected and components linked.

Terminal Blocks and Accessories

Terminal blocks are available in a range of sizes and types to suit different applications. There are heavy duty terminal blocks for use in industrial settings and lower voltage terminal blocks for residential and commercial uses. Accessories are available to make linking components quick and easy, such as nuts and bolts, washers, wire clamps, and ground terminals.

The wide range of components that can be connected to terminal blocks include AC and DC current, sockets, relays, control circuits, trunk cables, and other devices such as network switches, power supplies, shielding, and overload protection.

By using terminal blocks and their associated accessories, engineers, electricians, and technicians have an easy, reliable and safe means of connecting components in a range of applications. Safety remains a priority when working with electrical systems, and these accessories are used for just that.
