Abstract: A cable assembly includes a coaxial cable and a plug-and-socket (plug-in) connector part. The connector part has a sleeve, a sleeve contact, and a shielding module. The sleeve is connected to the outer conductor of the cable at a free end section of the cable and the sleeve contact is connected to the inner conductor of the cable. The shielding module includes a shielding plate and a chamber insert. The chamber insert is inserted into the shielding plate and receives the sleeve contact. The shielding module is connected to the sleeve such that the sleeve and the shielding plate surround the sleeve contact with the sleeve contact enclosed by the chamber insert up to a side of the sleeve contact intended for connecting along a direction of insertion with a contact pin of a mating plug-in connector.
