D-Sub connectors, often referred to as D-Shaped connectors, are electronically activated connectors used in a variety of applications. They are often used in the integration of computers, industrial automation and communication systems. The 206478-5 is a D-Sub backshell, hood and hood assembly designed to provide mechanical protection to the connector.

Function and Design

The 206478-5 D-Sub backshell is an IP67 rated high-performance backshell designed to protect the connectors from dust, liquids and other foreign material. It consists of three main components - the backshell, hood, and hood assembly. The backshell is made from two molded halves connected by two screws, and acts as a housing for the cable wrap that is used to provide strain relief for the wires and cables. The hood is an aluminum shell designed to provide protection for the connector housing itself. Finally, the hood assembly is designed to connect the backshell and the hood together, and provide additional shielding for the connector assembly.

Applications

The 206478-5 D-Sub backshell is often used in industrial automation systems, communication systems, and computer systems. Generally, these systems require the use of multiple connectors that are connected to each other. The backshell provides strong and durable protection for the connectors and cables, helping to extend the life of the system. In addition, the backshell helps to protect the system from dirt, dust, and other environmental factors. It is also designed to provide efficient cooling of the system by providing an insulated chamber for air to circulate around the connector.

Working Principle

The 206478-5 D-Sub backshell is an active connector in which the contacts are in constant electrical contact with each other. This allows electrical signals to pass from one connector to another. In addition, the backshell provides the required strain relief for the cable and wires related to the connector. In order for the electrical signals to travel efficiently between the connectors, the backshell is designed to provide a number of shielding layers. This includes an aluminum hood, which helps to protect the electrical signals from any external electromagnetic interference. In addition, the hood assembly helps to provide additional protection by allowing air to circulate around the connectors and providing an insulated chamber for the connectors.

Conclusion

Overall, the 206478-5 D-Sub backshell, hood, and hood assembly are designed to provide strong and durable protection for the connectors and cables in a variety of applications. The backshell is designed to provide an insulated chamber that helps to keep cables and wires safe from dust, liquids, and other foreign material. In addition, the hood provides additional shielding from electrical interference. And finally, the hood assembly is designed to provide efficient cooling of the system by allowing air to circulate around the connectors.
