Circular connectors, or round connectors, offer a wide range of sizes, allowing them to be used in a multitude of applications. The 217-8676-000 is one such example and is a particularly versatile connector. This article will discuss its application field, as well as the working principles behind it.

Application fields

The 217-8676-000 is a Military Standard (“Mil-Spec”) circular connector. The Mil-Spec/MIL-C-38999 Series I style and the miniature MIL-C-28840 Series I configurations are two common variations, as it is designed for use with a wide variety of applications in a range of areas, including aerospace, defense, industrial, telecommunications, and transportation. In terms of usage, it is highly suited for multiple install requirements, such as fields that require panel mount or removable receptacles with jackscrews, as well as board mount configurations. The 217-8676-000 circular connector can be used for signal and power interconnects, as well as for transmitting control, audio, video, data, and RF signals. It is also quite useful in applications that require high levels of vibration, such as ground and air vehicles.

Working Principle

The 217-8676-000 circular connector operates on the principles of insertion, contact alignment and retention. Firstly, the connector is inserted into the mating receptacle, where twist-lock latching is enabled if applicable. The design of the bayonet locking system ensures that contact points on each side, such as pins and sockets or female and male contacts, are parallel and that contact forces are applied evenly on the mating surfaces. This increases stability and reliability in data transmission. Secondly, insertion of the connector will also ensure that the contact points are properly aligned before firmly mating the connector.

The third principle used in the 217-8676-000 circular connector is contact retention. This refers to the ability of the connector to endure vibrations that can disrupt signals, as well as to protect the contacts from corrosion. Contact retention is achieved through the use of special mechanical locks, such as the double open end bayonet or split nut, which ensures that the contacts remain in accurate positions relative to each other regardless of the environmental forces applied on them.

Conclusion

The 217-8676-000 circular connector is an ideal choice for a number of applications, offering multiple advantages in terms of signal and power transmission. Its operating principles are based on three key components: insertion, contact alignment and retention, all of which are essential for ensure consistent and reliable connections. For these reasons, the 217-8676-000 is an excellent connector for industries such as aerospace, defense, industrial, telecommunications, and transportation.
