Terminal Blocks - Barrier Blocks

431612-26-0 Application Field and Working Principle

431612-26-0 is a type of Terminal Block, Barrier Blocks which specially designed for used in electrical and industrial electronic control systems. It\'s a miniature form of distributing power in a fast, reliable and economical way. Besides, with excellent insulation and security, Barrier Blocks provide stable connections and reliable performance in all kinds of applications.

For the application field, Barrier Blocks are predominantly suited for connecting power supply and application power circuits, and suitable for applications such as power supply modules, PLC control systems, CNC control systems, order picking systems, driving circuits, etc.

That\'s because Barrier Blocks is a standard, modular form of connecting that Electrical wiring and provide a durable connection between circuits. Furthermore, due to the robust design of Barrier Blocks, it prevents users from physical manipulation: the user can not use connectors with left-over contacts therefore it provides much greater safety.

Working Principle

Barrier Blocks is often mounted on a common pcb and/or a mounting plate. It makes by connecting a series of rectangular-shaped terminals, which ensures connectivity between two terminals, as well as providing robustness in high temperature or unusual environmental applications. There are various forms for Terminal Blocks, such as "populated" or "lateral-entry”.

In the process of using this Terminal Block, the steel part of each terminal is placed on the same side of the pcb, then the terminal block is rotating until the steel portion and pcb are at 90-degree angle, then the steel portion should be firmly pressed with the pcb. After that, the terminal block should be firmly pressed against the pcb to ensure good contact, then the copper strap of the other terminal should be fixed in the same way.

First, after screwing the terminal strip, put the copper terminal screw in the next terminal block hole, and then compress the plastic terminal block and tighten it with a screwdriver. When screwing the copper screw, pay attention to the tightening strength, do not be too tight, just tighten it with a hand touch. Additionally, the contact pressure between the terminal block and the insulated jacket at the same time should be uniform and the screw should be tightened at the same time.

Moreover, universal terminal blocks are used to interconnect two or more terminals, usually for power sources and components. It has a good resistance to electrical conductivity, heat insulation and oxidation and provides stability during power transfer from one point to another. As a result, it is widely used in industrial automation and other industrial electronic control systems.

In conclusion, Barrier Blocks does provides fast, reliable and economical way of distributing power. Its robust design prevents users from physical manipulation and also provides stability during power transfer from one point to another. In addition, that it also has excellent insulation and security to ensure safe connection which mak it ideal for a variety of applications.
