What This Strain Relief Does
The TE Connectivity 747275-2 is a D-sub strain relief accessory from the AMPLIMITE HDF-20 series, designed for use with HDF-20 ribbon cable connectors. It fits 25-position D-sub shells and clamps onto the cable exit to take the mechanical load off the IDC termination points — the part that sees the most flex stress in a harness. The strain relief body is a two-piece plastic shell that closes around the ribbon cable after it's terminated, with a slot that aligns to the connector backshell. No mounting hardware is included with this accessory; the strain relief relies on the D-sub connector's own jack-screws or slide-lock to hold the assembly together.
