What This CPC Cable Clamp Is
The TE Connectivity 828859-1 is a CPC (Circular Plastic Connector) cable clamp, part of the CPC accessory family. It is a strain-relief and cable-retention component designed for use with the corresponding CPC circular connector backshell or housing, securing the cable exit and preventing pull-out forces from reaching the contact terminations. This is a mechanical accessory — it carries no electrical rating itself but is specified for the environmental sealing and mechanical integrity of the mated connector assembly.
