The TE Connectivity 552760-1 is a 50-position one-piece backshell from the CHAMP.085 series, designed to dress and protect the cable exit on a mated CHAMP connector pair. It routes the cable bundle through a 90° turn, with an integrated strain relief that clamps the round cable jacket to take tension and flex off the contact terminations. The black thermoplastic housing is unshielded and intended for indoor equipment where EMI shielding is handled elsewhere in the assembly. This backshell is a mechanical accessory — it does not carry electrical ratings. Its job is to secure the cable bundle, provide strain relief, and give the harness a clean 90° exit from the connector face. The 50-position count must match the CHAMP.085 connector it covers, and the 90° exit angle is fixed; this part does not offer a straight or variable-angle option.
Cable Exit and Strain Relief — What the 90° and Hardware Mean for Routing
The 90° cable exit routes the round cable bundle perpendicular to the connector mating axis, which is the typical choice when the cable must run along the panel or enclosure wall rather than straight out the back. The integrated strain relief clamps onto the cable jacket — this is what keeps the crimp or solder terminations from seeing the pull load when the harness is moved or routed through a cable tray. Without it, the contacts inside the CHAMP connector would fatigue over repeated flex cycles.
