3049864 Application Field and Working Principle

Terminal blocks are essential elements of electrical equipment. They play a important role in transferring and connecting electrical power to other electrical components within a piece of equipment. They provide a convenient platform for connecting cables and enabling current to flow from one component to another as well as between multiple circuits. Din rail, channel and other types of terminal blocks are utilized in various industrial and commercial applications.

3049864 Din Rail Terminal Blocks
Din rail terminal blocks are generally designed for use with Din rail mounting systems. Connections are made through solderless screw-clamps, which allow wiring of multiple conductors or wires in a single connection. Din rail terminal blocks have a number of application fields such as automotive, telecom, control systems, security systems, industrial instrumentation, computing, audio equipments and energy distribution. They are suitable for use with diverse cables, wires and connectors.

Their working principle consists of gripping the sleeve of a standardized signal wire and displacement of an insulation shield. Such insulation shields allow to maintain the electrical separation of individual contacts. This design feature also ensures a secure connection and improved contact integrity. Existing contacts on the terminal blocks are interchangeable to accommodate various conductor sizes, shapes and insulation materials.

3049864 Channel Terminal Blocks
Channel terminal blocks are often utilized in applications that require power and signal power distribution from the main source to different destinations. These are designed for either single or multiple wire connections and are used for connecting two or more wires side by side. They are widely used in multiple machine frames, cabinets, control boxes and different electric inverter structures.

The working principle of these terminal blocks consists of three components: a terminal housing, an integrated wire clamp and the connector. The terminals are connected together internally by using a conductive material. The integrated wire clamp is responsible for both the electrical contact and the mechanical fixation of the wire. The integrated wire clamp acts as a bridge between the conductor and the attachment points of the terminal housing.

This design mechanism is to ensure a secured connection between the two and also limits potential mechanical stress which conductor wires might suffer from thermal cycling and other environmental forces. Electrical contact is also maintained through the mutual displacement of inner and outer shields, enabling reliable signal transmission in both directions.

Terminal blocks are commonly used in industrial and commercial applications. Din rail, channel and other types of terminal blocks are used for making connections between cables and conducting current from one circuit to another. They are designed to ensure a secure connection and maximum signal transmission in both directions. They provide a reliable medium for connecting various cables and wires and are essential elements of most electrical systems.
