Circular Connectors - Backshells and Cable Clamps

The M85049/41-10A is a circular connector backshell and cable clamp, designed to be used with M85049/41 series military circular plugs. It is also one of the most common backshell and clamps in the M85049/41 series, which includes variations in protection class, size, material and plating. This article will discuss the application field of the M85049/41-10A, and the working principle of the backshell and clamp.

Application Field

The M85049/41-10A is a protective device used in U.S. military applications. It features a space saving backshell, while providing the best EMI performance in its class. It is suitable for use in any system that requires MIL-C-27500 series connectors, such as secure communications systems and military avionics. It is also applicable to spacecraft launch vehicle equipment that requires high strength and stiffness of connector shells.

Working Principle

The M85049/41-10A cable clamp consists of a threaded clamp, a cable shield, and a locking gland. The threaded clamp is used to attach the connector’s backshells and to secure the cable shield to the backshell. The cable shield is the main conduit for providing EMI shielding. It is made of an outer aluminum shell and an inner conductive shielded plenum. When the clamp is tightened, the cable shield is compressed, providing an EMI tight seal.

The locking gland is used to ensure the backshell and cable shield remain firmly secured to the connector. It features two separate ports, one for the backshell and one for the cable shield, and a locking nut for each port. The locking nut is tightened to secure the backshell to the connector, while the other nut is tightened to secure the cable shield to the backshell.

Conclusion

The M85049/41-10A circular connector backshell and cable clamp is an essential component for a variety of military applications. It provides an EMI tight seal, while protecting the cable and connector from environmental contamination. The threaded clamp, cable shield and locking gland ensure that the connection is tightly sealed, providing a long lasting and reliable connection.
