What this strain relief does on a CHAMP connector
The TE 1-552027-1 is a 50-position strain relief from the CHAMP series, designed to clamp onto the cable exit of a CHAMP D-Sub connector. It absorbs flex and pull at the wire bundle so the termination points inside the connector body don't fatigue over repeated handling or vibration. If you're building a harness with a 50-position CHAMP plug or receptacle, this is the back-end accessory that keeps the cable-to-contact junction intact through the life of the assembly.
Position count and series fit
This strain relief is made for 50-position CHAMP D-Sub connectors. The CHAMP series covers a range of position counts — 14, 24, 36, 50, 64 — and each position count uses its own dedicated strain relief shell. The 1-552027-1 fits only the 50-position variant; the shell cavity and clamp footprint change with the connector body size. No cross-reference or universal equivalent is on record for this part.
