Which connector type uses a coupling ring that slides along the axis?

• A. Push-Pull coupling
• B. Screw coupling
• C. Bayonet coupling
• D. Interlock coupling

Answer: (A)

The main idea here is how the locking sleeve moves to connect or disconnect. In a push-pull connector, you mate the plug and receptacle and then slide a coupling ring along the axis to lock them together. This axial sliding collar is the distinctive feature of the push-pull style, allowing quick, non-rotational connection and disconnection even in tight or vibration-prone environments. In contrast, screw-type connections require rotating a threaded nut, bayonet-type connections need a push-in followed by a twist, and interlock types use a locking mechanism that doesn’t rely on sliding a collar along the axis.
