What This Crimp Flange Does in the D-Sub Assembly
The TE Connectivity 2-2308348-2 is a crimp flange accessory sized 12 large, designed for use with D-Sub backshells. It secures the cable jacket at the backshell exit, providing strain relief and a clean termination point for the cable braid or overall shield. This is the part that keeps the cable from pulling on the solder bucket or IDC contacts inside the backshell — skip it and the whole assembly relies on the contact retention alone.
