Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks are essential components for any industrial power distribution and electrical system. Their primary function is to allow connection points for electrical power and signals. The 1911473 series terminal blocks, also known as ASI headers, plugs and sockets, are made to meet stringent UL standards for safety and applications in industrial settings. Each product in the series has different characteristics and specifications to serve specific roles in electricity and signal distribution, making them a versatile and highly useful range of terminals.

Applications

The 1911473 series is intended for use as power or signal distribution blocks in industrial and other heavy-duty electrical systems. They are designed to connect various parts of a system in a safe and secure manner, with snap-action locking pins that can be easily engaged or released as needed. This makes them well-suited for safety applications in order to ensure that all connections remain secure and short circuits are avoided. In addition to power and signal distribution, they are also suitable for use with high voltage and power as they have a durable construction and materials that are designed to withstand higher levels of current than found in regular industrial applications.

Plug Styles

An important aspect of selecting the 1911473 series of terminals is the type of plug. The plug is the component that is inserted into the header or socket. In the 1911473 series, there are three plug types available: vertical, right angle, and differential. The vertical plug is the most commonly used and is used for simple electrical connections. It is relatively easy to insert and remove and is also resistant to accidental misconnections. The right angle plug is designed for applications where space is limited. It has a 90° angle from the header and plugs in sideways. The differential plug is designed for power supplies or when there is a need for dual circuitry. It has two parallel connectors for each side and is ideal for polarized electronic components.

Header Styles

The header is the component of the terminal block that the plug inserts into. In the 1911473 series, there are two header styles available: single and double. The single header is suitable for single wiring applications and is designed for both the vertical and right-angle plugs. The double header is more suited for dual-circuit applications and is designed for the differential plug only. It has two drilled holes and is used for both power and signal connections. The two-hole connection allows for several connections between the two separate circuits.

Sockets

Sockets in the 1911473 series are used for applications where it is necessary to disconnect and reconnect quickly, such as for testing or maintenance. The sockets are available in both vertical and right-angle variations to fit the plug type chosen, with high quality contacts designed for a secure, reliable connection. They are also UL listed for use in high voltage applications, allowing for more creative solutions to power and signal distribution requirements.

Materials and Construction

The 1911473 series is made from a combination of steel and copper for strength, with zinc plating for added corrosion protection. The plugs and headers are also finished with a layer of nickel for additional protection and durability. In addition, the plugs and headers have a double-hinged design that enables them to be inserted without causing additional pressure on the contacts, making them safe to use in high voltage systems.

Working Principle

The 1911473 series of terminals allow for easy and secure connection of electrical equipment. The plugs are inserted into the corresponding headers, and the latching pins securely hold the plug in place. The cables are connected to the terminals on the plugs and the header, creating a connection between two power sources. The double-hinged design of the plugs and headers also ensures that there is no additional pressure on the contacts, making them more reliable and less likely to experience corrosion.

Conclusion

The 1911473 series of terminals are a versatile and reliable choice for a wide variety of industrial applications. Their rugged construction ensures a safe connection that can withstand the demands of harsh industrial environments, while their various plug and header styles offer flexibility in terms of electrical and signal connections. With UL approval for use in high voltage systems, they make an excellent choice for any industrial application.
