What This Crimp Flange Does in a D-Sub Assembly
The TE Connectivity 2-2308348-1 is a crimp flange — a metal or plated bracket that clamps the cable shield and jacket to the back of a D-sub backshell. It is the 11 large variant, sized for the larger cable-entry opening on the corresponding backshell half. The flange wraps around the cable, and when the backshell screws together, the crimp ears bite into the braid to establish a 360° shield termination and a strain-relief grip on the cable jacket. This is an accessory, not a connector — it does not carry signals itself. It completes the mechanical and electrical termination of the cable shield at the backshell, which is the step that keeps radiated emissions inside the cable and external noise out of the signal pair.
Sizing It Against the 2-2308348-2 Sibling
The 2-2308348-1 is the 11 large crimp flange; the 2-2308348-2 is the same accessory type but a different size variant under the same base product number 2308348. Both are active, both ship in a Box package, and both are for use with D-sub backshells. The size difference — 11 large vs the sibling's dimension — determines which cable diameter range the flange accepts. Match the flange size to the backshell's cable-entry bore and the cable's outer diameter before ordering.
Installation Sequence on a D-Sub Backshell
The crimp flange slides over the cable before the backshell halves are assembled. Slide the flange onto the cable first, then prepare the cable end — strip the jacket to expose the braid and the individual conductors. Dress the braid over the cable jacket, then position the flange so its crimp ears sit over the braid. Crimp the ears with a standard crimp tool sized for the flange material. Once crimped, the flange sits captive on the cable, and the backshell halves close around it, with the flange's outer profile seating into the backshell's internal groove.
