The TE Connectivity 552496-1 is a 90-degree cover kit — a cap (cover) with integrated strain relief — designed for 64-position CHAMP D-Sub connectors. The 64-position count must match the connector it covers; this is not a universal fit across different position counts within the CHAMP family.
Strain Relief and Cable Exit
The integrated strain relief grips the cable bundle exiting the connector at a 90-degree angle, routing the cable parallel to the panel or board face. This is the primary reason to specify this cover over a plain backshell — it prevents cable pull from transmitting force to the solder or crimp terminations inside the connector. For a 64-position CHAMP D-Sub carrying a dense cable bundle, the strain relief reduces fatigue at the termination point in applications where the cable is flexed or routed through tight spaces.
Compatibility: Which Connectors It Fits
This cover kit is intended for use with CHAMP D-Sub connectors — the TE family of high-density D-Subminiature connectors with a 0.050-inch (1.27 mm) contact pitch. It fits any 64-position CHAMP D-Sub plug or receptacle housing. It does not fit standard-density D-Sub connectors (DB, DC, DD series) because the CHAMP footprint and shell dimensions are different. If you are working with a 64-position CHAMP connector, this cover is the correct mate.
