Terminal Blocks – Wire to Board: Application Field and Working Principle

Terminal blocks, also known as terminal strips, are devices that connect wiring and provide an electrical connection to a circuit. The connection from wire to terminal blocks is made through the soldering of the individual contact points. Terminal blocks are used in a variety of applications that include industrial automation, commercial electronics, medical electronic, power and lighting control systems and more. In this article we will discuss the application field and working principle of terminal blocks in the wire to board segment.

Terminal blocks that are used for wire to board connections offer several advantages over other connection methods, such as screw terminals and connectors. Just as with screw terminals, the connection can be made with minimal effort and without additional tools. However, with terminal blocks there is no contact wear or oxidation of the contact points, which also makes them very reliable and long lasting. Additionally, they can easily be connected with other terminal blocks and used to isolate circuits. Finally, terminal blocks allow for easy removal and installation of components within a circuit, when maintenance is needed.

There are several types of wire to board terminal blocks that vary in design. Typically, they consist of two components - a base and a screw terminal. The base incorporates a mounting base which is used to secure the terminal block to a mounting surface. This could be a panel, a PCB or even a PLC. The base will then have a set of contact points that will be used to connect the wires to the terminal block. Finally, the screw terminal is used to tighten the wire connection firmly in order for it to remain securely connected. The design of the terminal block also includes insulation to provide protection from any short circuits that may occur.

The working principle of terminate blocks in the wire to board segment is relatively simple. The base of the terminal block has two contact points, one connected to ground and one connected to power. When a wire is inserted into the terminal block, the two contact points make contact with the exposed conductive material, completing the circuit. The connection is further secured by the screw terminal being tightened into the base, which locks the two contact points together. It should be noted that the wire connection should also be securely connected with solder or a similar method to ensure a safe and durable connection.

Terminal blocks in the wire to board segment are a cost effective and reliable option for many application fields. They offer a secure and dependable connection that can withstand high electrical currents and vibrations. Additionally, they are also very easy to install and require minimal maintenance. For these reasons, terminal blocks have found a wide variety of applications, including telecommunications, industrial automation, medical electronics and more.
