A module connector for electrically connecting a pair of electric modules includes a pair of contact assemblies spaced from one another and fastening the module connector to the electric modules, a conductor assembly electrically connecting the contact assemblies and, with the contact assemblies, forming an electrical connection between the electric modules, and a housing formed of an electrically insulating material. The contact assemblies and the conductor assembly are accommodated in the housing. At least one of the contact assemblies is fastened to the conductor assembly in a manner displaceable relative to the conductor assembly in a direction of displacement directed towards and/or away from the other of the contact assemblies.
