Abstract

A plug-in connector that can be manufactured using MID technology, which nevertheless ensures good crosstalk compensation and thus a high data transmission rate has two assembled contact carrier parts with contacts are disposed between these contact carrier parts. A separate, electrically conductive compensation coating may be provided in each contact carrier part, each having a connection surface for producing an electrically conductive connection to an associated contact. Each of the electrically conductive compensation coatings has at least one coupling surface for a targeted capacitive coupling with one or more further contacts. Between each coupling surface and the associated contact, an insulating film or part of an insulating film is provided, which acts as a dielectric and a spacer. By selection of the contacts to be coupled and the capacitance of the coupling, good compensation of undesired crosstalk can thus be achieved in a simple manner.
