ABSTRACT:
A printed circuit module comprises a printed circuitboard equipped with integrated modules, a connector part and a contact pressure part exerting a pressure on a printed circuitboard surface, for example, a cooling device. In order to prevent warping or bending of the printed circuitboard due to the contact pressure component or due to plugging and unplugging operations, and from causing line breaks or the like, a counterpressure on the printed circuitboard is generated and a flexible connection is established between the connector part and the printed circuitboard. To this end, contacting elements of the connector part are uniformly, aerially distributed over the printed circuitboard. They respectively comprise a spring shaft for receiving a contact pin and a connecting lug resting against the printed circuitboard in a spring-like manner and whose end adjoining the contact guide surface is designed in the form of a straight metal strip and presses with its end face 3 onto to the contacting surface, and whose other end is connected to the spring shaft via a leaf spring portion bent in a wavy manner.
