Abstract: A plug connector comprising a first contact support, in which contacts are disposed, which enter an electrical connection with mating contacts of a second contact support, when the contact supports are joined. The first contact support comprises first coding device, which interacts with a second coding device of the second contact support and assures a defined joining of the contact supports in order to connect the contacts and the mating contacts.

Abstract: The invention relates to a plug connector comprising a first contact support, in which contacts are disposed, which enter an electrical connection with mating contacts of a second contact support, when the contact supports are joined, wherein the first contact support comprises first coding device, which interacts with a second coding device of the second contact support and assures a defined joining of the contact supports in order to connect the contacts and the mating contacts. It is the object of the invention to simplify the production of plug connectors, in particular plug connectors with mechanical coding devices. The object is accomplished through a plug connector according to claim 1, which is in particular characterized in that at least one contact support comprises a receiver for a coding device configured as a separate component.
