What this backshell does for the CPC connector assembly
The TE Connectivity 206966-9 is a backshell and cable clamp for the CPC (Circular Plastic Connector) series, shell size 13. It provides strain relief and cable retention at the rear of the connector, with a 180° cable exit that routes the cable straight out the back. The 3/4-20 UNEF thread mates directly to the connector shell, and the 0.453" (11.51 mm) cable opening accepts the cable bundle that passes through the clamp. The kit includes the clamp body and two mounting screws — no separate hardware sourcing needed for a single assembly.
Thread fit and cable clearance
The 3/4-20 UNEF thread mates to the CPC connector shell. The 0.453" (11.51 mm) cable opening sets the maximum cable bundle diameter.
The black color is standard for the CPC backshell line. No plating is listed — the clamp is a non-conductive mechanical part, not a current-carrying component.
