A contact device for plugs is arranged on the component side of the printed circuitboard and includes soldered connections which penetrate through the printed circuitboard and are soldered to conductor paths of the printed circuitboard on the opposite side thereof. The countercontacts of a plug can be inserted from the soldering side of the printed circuitboard and penetrate through a recess through the printed circuitboard. The purpose of the invention is to provide a contact device which can be applied together with the components from one side of the printed circuitboard by way of an automatic equipping machine. Accordingly, at least one plug receptacle forms the contact device. The plug receptacle includes two flanks which serve for mechanical and electrical fastening to the printed circuitboard and between which a plug tongue is arranged for contacting the respective countercontact of the plug.
