Terminal Blocks - Headers, Plugs and Sockets

1672340000 is an international standard developed by the European standardization organization CENELEC EN 50045. It is mainly used in terminal blocks such as headers, plugs and sockets. The standard applies to the production of products used in electro-mechanical electrical wiring and connection between power supply and load. It specifies performance and test requirements, dimensional specifications, marking, verification methods, test instructions and environmental requirements.

Applications

Terminal blocks such as headers, plugs and sockets are widely used in various fields with 1672340000 standard, including but not limited to industrial electrical distribution, electrical instrumentation, robotics, communication or multimedia control systems. Specifically, It is often used in the following areas such as shipbuilding, container plants, raw material plants and nuclear engineering.

Working Principle

The working principle of the terminal block and constraints of electrical connection can be determined mainly based on the type of the device. Terminal blocks are generally classified into three types by their working principle: screw, fasteners, and insulation piercing connections.

Screw terminal blocks with mechanical connection, through screw compression, good contact force, low sliding contact resistance and high reliability are widely used. This type of terminal block generally M3 stainless steel screws for fastening, then the terminals will be clamped with it. Its main advantage is its good performance on heavy load.

Fastener terminal blocks usually connect the connector block and contact block by fastening screws. This type of terminal blocks is especially suitable for frequent connections. It is widely used in the connection of power automation, industrial power control, breaker control, instrument transformer and so on.

Insulation piercing connections terminal blocks are used in transmission lines with very high voltage per unit area and very long distance transmission. The wire is clamped into U-type contact gaps and the surface of the wire is pierced through the insulation layer without removing the insulation layer of the wire. This terminal blocks are also used in an environment where a lot of interference sources exist.

Advantages

The terminal blocks manufactured according to the CENELEC EN 50045 standard has the advantages of standardization, safety and convenience. Products also have the advantages of good insulation performance, high impact resistance, good connection stability, fast installation and convenient transportation.

Safe and convenient terminal blocks are manufactured using a variety of insulation materials, installation methods and connection types. It provides a reliable and convenient electrical connection to ensure that the connection can withstand thousands of mechanical and electrical connection life.

Terminal blocks have contributed significantly to the reliability, safety and stability of power control and industrial control system, and have achieved the observed requirements of the connection through the development and improvement of technology and materials. The CENELEC EN 50045 Standard have played a crucial role in this.
