Contact assembly for a combined power and data connector and socket assembly for a mating connector socket

The invention relates to a contact assembly (1) for a combined power and data connector (3) and to a socket assembly (115) for a mating socket (117). In order to provide a combined power and data connector that allows combined transport of electrical power and data signals, which is compact, solid and may be produced cost-effectively, it is intended according to the invention that a connector face (5) of the contact assembly (1) comprises a data section (13) and a second section (10), wherein the data section (13) comprises a plurality of data contacts (43), which are separated from the second section (10) by at least one separating wall assembly (29), the data contacts (43) being arranged on a carrier unit (33) that is mounted on a data section side (31) of the separating wall assembly (29), that the carrier unit (33) further carries electric power and wherein the at least one separating wall assembly (29) comprises a fixation subassembly (53) that fixates the carrier unit (33) onto the separating wall assembly (29).
