Abstract

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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 160 words
In a printed circuit structure of the type in which at least one electric module engages a cooling device on one side thereof and engages a plurality of contact surfaces of a printed circuitboard on the other side thereof, and in which the contact surfaces are respectively contacted by electrical contacts of an electrical connector which extends over the entire printed circuitboard and which has passages therethrough for the electrical contacts, the improvement wherein: a reinforcing plate is carried by the printed circuitboard and includes a plurality of holes aligned with the contact surfaces of the printed circuitboard; and each of said electrical contacts comprises a spring sectin for receiving plug pin, a straight flat metal strip including an end face engaging the respective contact surface, and a wave-shaped leaf spring integral therewith and connecting said straight flat metal strip and said spring section, said straight flat metal strips contacting said contact surfaces through said holes of said reinforcing plate.
Claim 2
Dependent Claim 160 words
In a printed circuit structure of the type in which at least one electric module engages a cooling device on one side thereof and engages a plurality of contact surfaces of a printed circuitboard on the other side thereof, and in which the contact surfaces are respectively contacted by electrical contacts of an electrical connector which extends over the entire printed circuitboard and which has passages therethrough for the electrical contacts, the improvement wherein: a reinforcing plate is carried by the printed circuitboard and includes a plurality of holes aligned with the contact surfaces of the printed circuitboard; and each of said electrical contacts comprises a spring sectin for receiving plug pin, a straight flat metal strip including an end face engaging the respective contact surface, and a wave-shaped leaf spring integral therewith and connecting said straight flat metal strip and said spring section, said straight flat metal strips contacting said contact surfaces through said holes of said reinforcing plate.
