MS3158-20C application field and working principle

Circular connectors are commonly used to make electrical connections between two or more components or cables. The MS3158 series of connectors are a type of circular, modular, mil-spec connector. The -20C model includes a standard breakout backshell and cable clamps ideal for applications where stress relief to the cable is required.

Application Fields

The MS3158-20C is most commonly used in the aerospace and military equipment industries, however it they can be used in a wide range of applications including medical, communications, entertainment and display systems, instrumentation, transportation equipment, mass transit, industrial computing, military vehicles, telecommunications, and robotics.

Working Principle

MS3158-20C connectors are designed to provide a reliable electrical connection for a wide range of applications. The connector’s contact surfaces are plated with either gold or cadmium over nickel, and the mating surfaces are surrounded by an insulating sleeve. The contacts on the connector are inserted into the backshell and cable clamps, then held in place by a locking insert. The metal clamps provide strain relief to the connected cable, preventing critical electrical junctions from being affected by outside forces.

The contact pins on the connector have a crimped barrel, ensuring that the connection remains strong and reliable. These crimped contacts also provide a secondary form of strain relief in addition to the cable clamps, further protecting the electrical connection.

Conclusion

MS3158-20C connectors provide a reliable electrical connection for a wide variety of applications in the aerospace and military industries. The combination of a breakout backshell and cable clamps provide superior protection for the connected components from outside forces. The contact pins provide a secure connection through the use of crimped barrels, and the insulating sleeves provide electrical isolation between the mating surfaces. The MS3158-20C connectors are an ideal choice when a robust and reliable connection is needed.
