Circular Connectors - Backshells and Cable Clamps are components designed for use in many applications. 71-74911-4 is one such connector, which is a part of this family.

The 71-74911-4 is a round back shell used for strain relief. It is designed to fit any connector having between three and twelve contacts. It is made from polytetrafluoroethylene (PTFE) plastics, and is designed to protect the wiring inside electrical connections from physical damage due to strain, flexing, or external forces.

The backshell itself features two parts: a mating surface and a closing surface. The mating surface features compliant legs that form a bump around the circumference of the connector, which holds the backshell to the mating surface. The closing surface features a groove which ensures that the tension created by the mating surface is evenly distributed across the entire circumference of the backshell. The tension created by this design ensures that the wires in the electrical connection are firmly secured, while still allowing for some give due to strain or flexing.

The 71-74911-4 also features a cable clamp, which is designed to provide strain relief for the wires inside the electrical connection. The cable clamp is adjustable, and is capable of providing a clamping force of up to 200 pounds. It is made of PTFE, and is designed to prevent the spread of heat due to electrical current.

Overall, the 71-74911-4 is a versatile component for electrical connections, providing strain relief, flexibility, and protection from physical damage due to strain or flexing. Its design, featuring the two-part backshell and adjustable cable clamp, has made it popular for many types of applications, such as aviation, medical devices, and aerospace.
