Ring connectors have been used for decades in electrical engineering and have numerous different variants. The 51979-3 (or EN 1216 2003 Standard) is a specific standard of a three-pole ring connector, and is used in both military and aerospace applications. The ring connector is composed of a connector body, a locking collar, and a wired contact wiring terminal.

Application Field

The 51979-3 standard ring connector is used in a variety of applications, including:

• Aircrew systems
• Heavy equipment systems
• Marine systems
• Ground vehicle systems
• Missile systems
• Power systems
• Industrial systems

In general, the 51979-3 is used in any application where high electrical integrity is required due to the high contact ratings and low electrical resistance.

Working Principle

The 51979-3 ring connector is designed to be reliable and secure when installed, and to ensure that contact is maintained between the connected components. The connector has three wire contact terminals, each of which is connected to a corresponding conductor in the application. The wiring terminals are then connected to the connector body, which is fitted with a locking collar. The locking collar is used to secure the connection and ensure that the connector does not disconnect when subjected to vibrations, shock, or other environmental conditions.

The contact terminals are designed to provide an electrical connection with a low electrical resistance, and a high contact rating, ensuring that a reliable connection is maintained between the components. The contact terminals use an internal crimp design to ensure that the connection is securely maintained.

The overall design of the 51979-3 ring connector ensures that it can be used in a wide range of applications where a reliable and secure electrical connection is required. The design ensures that the connection will remain secure when subjected to harsh environmental conditions.
