Figure 3-1. Coaxial Connector Examples
These connectors are available in two coupling styles – Bayonet or Threaded:
• Bayonet Coupling Style – The jack has a pair of guideposts that accommodate the plug’s
lockdown slots. This lockdown design provides secure assembly without over-tightening
the connection.
• Threaded Coupling Style – The jack features external threads. The plug shell features
internal threads, and has either a knurled outer surface to permit hand-tightening of the
connection, or hex flats to accommodate torqued installation.
Connection Instructions:
• Bayonet Coupling Connections: Use the plug slots to guide, then slide the plug onto the jack
posts. Then, turn the plug clockwise until the jack posts are fully seated within the plug slot.
• Threaded Coupling Connections: Engage the plug onto the jack threads, and then turn the
plug clockwise until it is fully threaded onto the jack. Do not over-tighten the connection.
