ABSTRACT:
A logic card comprises a printed circuitboard equipped with integrated modules, a plug connector and a contact pressure component, for example, a cooling device, which exerts a pressure against a surface of the printed circuitboard. In order to prevent sag of the printed circuitboard which could result by the contact pressure component, or to prevent line ruptures and the like caused by plug-in and pulling events, a counterpressure is generated against the printed circuitboard and an elastic connection is produced between the plug connector and the printed circuitboard. To this end, the contacting elements of the plug connector are uniformly, planarly distributed over the printed circuitboard. Each comprises a spring shank for receiving a contact pin and a terminal lug for resiliently pressing against the printed circuitboard.
