Heavy Duty Connectors – Housings, Hoods, Bases

Heavy duty connectors are specialized, robust components which are utilized in heavy industries like telecom, engineering, and cable management. They are necessary when connecting large power systems in areas where repeated operation or other external forces might otherwise cause a particular connector to fail. The main advantages of employing heavy duty connectors over other types are their longer lifetime, higher current-carrying capacity, and improved durability.

1771891 – Housings

The 1771891 heavy duty connector is a type of housing, specifically designed to provide an efficient interconnect solution in space-constrained applications. It is made from die-cast aluminum alloy for improved durability and enhanced electrical performance. Its features include an internally threaded housing which can be mounted on either a tube or a panel surface, providing a seamless connection for large-scale electrical system designs. It has anti-vibration, shock resistance, and EMI/RFI shielding to protect against external influences. Its snap-fit design ensures quick, reliable connections while securing the parts of the system, minimizing any risk of failure or damage.

1771891 – Hoods

The 1771891 hood is a specialized component designed for use with the 1771891 connector housing. It is fitted with a lock chain for improved safety and easy mounting in exposed areas. Its design includes a dust cap cover to protect against moisture ingress, as well as an external o-ring for preventing liquid contamination. The hood is rated up to 130A and can withstand temperatures up to 125°C, making it suitable for a variety of industrial applications. It also provides complete 360° electrical shielding to protect delicate components.

1771891 – Bases

The 1771891 base is a heavy-duty connector system that is designed for external installation. It is constructed from die-cast aluminum and features an encapsulated back end which provides complete environmental protection. It is equipped with an external clamp for secure installations and has a robust, vibration-resistant design. Its brass contacts guarantee low contact resistance and improved quality copper contacts … which guarantee excellent electrical performance. The base is rated for current-carrying capacity up to 400A, making it suitable for large-scale industrial applications. It is equipped with an earthing cable for ground connection and features a lock-in-place feature for added safety.

1771891 – Working Principle

The 1771891 connectors feature an integrated spring connection system for easy installation. The system utilizes the tension generated by springy metal contacts combined with a special clip to ensure a reliable connection. The housing and hood components are locked in place during installation and the clip is installed as the last step, which provides a secure connection. The spring connection system significantly reduces installation time and provides improved reliability and durability even in harsh conditions.

Conclusion

The 1771891 series of heavy duty connectors provides reliable interconnection solutions in many industrial applications. Its die-cast aluminum components are robust and long-lasting, while its spring connection system ensures secure connection with minimal installation time. Overall, the 1771891 is an excellent option for large-scale equipment that requires reliable power connections in difficult environmental conditions.
