Terminal Blocks - Barrier Blocks

The 0387212812 application field and working principle refers to the use and operation of terminals blocks and barrier blocks. Terminal blocks are components used to connect two or more conductors or wires electrically. Barrier blocks are designed to block access to certain terminals and usually are not designed to control current or voltage. This article will discuss the application field and working principles of both terminal blocks and barrier blocks.

Application Field of Terminal Blocks and Barrier Blocks

Terminal blocks are very versatile and can be used in many different applications. They are commonly used in the electronics industry for connecting printed circuit board components and wire harnesses. In addition, they are also used in industrial control panels for safety hazards or to provide a ground via a grounded conductor. Terminal blocks can also be used for connecting transducers, relays, timers, and sensors.

Barrier blocks, on the other hand, are mainly used for electrical isolation purposes. They can be used to prevent accidental electrical contact of a potential shock hazard or to protect certain terminals from accidental contact. These devices are mainly used in hazardous areas and can be used to block access to the terminals. They are also used in electrical control systems when dealing with high voltage.

Working Principle of Terminal Blocks and Barrier Blocks

Terminal blocks are basically composed of two parts. The first part is the top portion which consists of a terminal post, which can be either insulated or conducting. The second part is the bottom portion which consists of a spring clip that is placed at the rear and contacts the insulation of the cable. The top portion then connects the springs clip to the terminal post.

When using a terminal block, the wires to be connected must be stripped of their insulation and wired around the terminal post. The spring clip at the rear helps keep the wires secure and the terminal post is tightened to prevent the wires from coming loose. In addition, a nut and washer can be added to increase the strength of the connection by holding the wires in place.

Barrier blocks work by using a series of independent circuits. Each circuit is electrically isolated from the others and is connected through a barrier that prevents the current or voltage from crossing over into the other circuits. This isolation helps to prevent undesired current or voltage from entering a particular circuit. In addition, barrier blocks can be used as switchable dividers to isolate or combine two or more circuits.

Conclusion

Terminal blocks and barrier blocks are essential components for many industries. Terminal blocks provide electrical connections between wires and can be used in many different applications. Barrier blocks provide electrical isolation for certain circuits and prevent accidental contact of high voltage current or voltage. Both are important components for many industries and understanding their application field and working principles is important when using them.
