Terminal Blocks - Barrier Blocks are a type of electrical connector used for separating conductors formed using various materials. Among these materials, SEFX-22 is one of the most popular. This article describes the application fields and working principles of the SEFX-22.

Application Field

SEFX-22 is mainly used for separating conductors in various fields, such as power industry, communications industry and automation industry. Its characteristics of superior reliability, flexible design, and cost-effective advantages make it suitable for these purposes.

Firstly, regarding the power industry, SEFX-22 can be used for connecting the main power, transformer, and distribution box, ensuring the secure transmission of electricity. Furthermore, its barrier terminals make it an ideal connection tool for signals and high voltage applications. In addition, it can also be installed in the furnace, rolling machine and machine tools for reliable transmission of electricity.

As for communications industry, SEFX-22 can be used in the wiring of internet protocol (IP) networks, providing a secure connection between IP devices. It is also used for the transmission of telecommunication signals in fiberoptics, allowing data to flow without interference. Besides, SEFX-22 is also applied in automobiles, ships and military control systems as a device of signal transmission.

In the automation industry, SEFX-22 is mainly used for connecting actuators, relays and indicator lights. Its terminals are designed to provide a secure connection so as to prevent signal losses or interference. Furthermore, its assembling function and flexible design allow it to meet various requirements from a wide range of applications, such as functions of control panel building, assembly line automation and machine assembling.

Working Principle

The working principle of SEFX-22 is based on the principle of electrical contact. The contact of the terminals depends on the formation of a difference in pressure between the terminals. When the voltage at the terminals reaches a certain level, the contact is formed. This is also the reason why the contact between the terminals is very reliable, which can prevent the electricity from leaking and thus achieves the effect of separating conductors.

SEFX-22 is specially designed to provide reliable electrical connections. Its built-in structure is composed of a dielectric insulator, contact and bridge contact. The insulator acts as a barrier between the cables and the contact, preventing electrical leakage and protecting the contact from damage or corrosion. The contact is made of copper material and it is responsible for providing the connection to the cables. The bridge contacts are designed to provide a reliable connection between the contact and the conductors.

The design of SEFX-22 is also very flexible in order to accommodate various connection methods. Generally, it can be used with crimp terminal lugs, screw terminal lugs, and pin & socket connection systems. The crimp terminals are used to make a secure connection between the conductor and the terminal contact. The screw terminals are used to form a mechanical connection with the pin & socket connection system, providing a high level of security for the connection.

In conclusion, SEFX-22 is a type of electrical connector used for separating conductors. It is mainly used in power industry, communications industry and automation industry and its working principle is based on the principle of electrical contact. Its cost-effective advantages and flexible design allow it to meet different requirements and provide reliable and secure electrical connections.
