Introduction

Terminal blocks are one of the most common and versatile connector types available for use in electronic systems applications, such as signal interconnection, device connection and power supply. Introduced in the early 1900s, these components are now commonplace in many environments, including industrial machinery, computers, vehicles, appliances and more. Wire-to-board terminal blocks, also known as 18700470000 applications, are a vital part of an effective wiring solution.

Terminal Blocks - Wire to Board

They offer reliable secure connections between wires and boards, without the need for soldering or crimping. These are especially suitable for devices such as relays and on-off switches and provide a simple way to manage large groups of wires.A terminal block consists of a base unit upon which are mounted wire contacts which are usually arranged in a vertical line with posts at either end. When wires are inserted into the contacts, they need to be held securely and the terminal block provides the necessary pressure to do so, without damaging the insulation on the wire. This is done by the action of a clamp or clip that is pushed onto the Wire, pressing it onto the contact and maintaining the connection until the pressure is released.Wire-to-board terminal blocks are typically rated for either a standard or high current application, often up to 16A in wiring projects and sometimes up to 100A or more for power supply applications. They come with both vertical and horizontal orientations, so that they can be used in a wide range of layout arrangements.

Working Principle

The working principle of a wire-to-board terminal block is relatively simple. The contact is usually a male pin or socket which is soldered to the board and into which a wire is inserted. The wire is held firmly in place by a clamp or clip attached to the terminal block. This clamp applies pressure to the wire, folding and wrapping the strands of the outer insulation over the contact pin or socket. When the wire is pressed down, this contact wraps around the pin or socket which in turn is securely soldered onto the board.The difference between a horizontal and a vertical orientation is simply the arrangement of the contacts on the block. In a horizontal orientation, the contacts are arranged in an even pattern across the length of the block and in a vertical orientation, the contacts are arranged in a series down the length of the block.

Conclusion

In conclusion, terminal blocks are vital components in all types of electrical and electronic systems. They enable secure connection of wires to a terminal or board and can even be used to manage large groups of wires. Wire-to-board terminal blocks, also known as 18700470000 applications, are invaluable in providing reliable connections and a simple way to organize multiple wires. With a choice of horizontal and vertical orientations and a wide range of ratings, they can be used effectively in any kind of system.
