Circular Connectors - Backshells and Cable Clamps

Circular connectors are versatile components used in a wide variety of applications. They are primarily used to stablish electrical connection between two wires, cables or components and are generally divided into two main categories: backshells and cable clamps.

M85049/10-11N Application Field and Working Principle

The M85049/10-11N is a type of circular connector backshell from the military COTS (Commercial Off The Shelf) range of connectors. This particular connector is a shielded connector designed for wireless communications applications and provides low-cost solutions for military and aerospace systems. The M85049/10-11N backshell is a single-piece, self-locking friction-style backshell, which features a robust 360° shielded housing and easy assembly. It is designed to be used in a wide range of electronic systems, including embedded systems, unmanned aerial vehicle (UAVs), rotorcraft avionics, communication radios, and satellite systems.The connector’s working principle is based on the fact it is a self-locking single-piece backshell. This type of backshell is held in place by a spring clamp, which fits around the circumference of the connector’s housing, locking the backshell in place. The contact pins inside the connector are connected to the wires from each side of the assembly. The backshell’s assembly is comprised of an outer shield, which is attached to the housing, which in turn is attached to an inner shield assembly. Connectors lie between the two shield parts and when tightened, they securely hold the cable in place. A key benefit of the M85049/10-11N connector is that it meets stringent military performance requirements for RF interference and RF transmission. It features a durable, waterproof housing that can withstand extreme environmental conditions, such as extreme temperatures and vibration. Additionally, the connector is resistant to corrosion and vibration, as it features precision machined parts that provide effective shock and vibration performance.

Conclusion

The M85049/10-11N backshell is a highly durable circular connector that is designed to provide reliable electrical connections in the most demanding environments. It features a robust 360° shielded housing that provides superior vibration and shock performance and is resistant to corrosion and RF interference. The incorporation of a spring clamp also ensures secure retention and easy assembly. Overall, the M85049/10-11N is an ideal choice for military and aerospace communications applications and provides a low-cost solution for a wide range of electronic systems.
