Abstract

The device has a metallic housing receiving a plug-in circuit board (2) which is retained within the housing via fixing springs (3). The latter are made of metal and cooperate with parts (4) of the metallic housing upon insertion of the circuit board, for providing an electrical contact between the housing and an earth terminal of the circuit board. Each fixing spring may be integrated in a plastics injection moulded locating rail (6) for the plug-in circuit board, with an electrically conductive surface provided at the point of contact of the spring with the circuit board.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Eine elektrisches Gerät nach der Figur weist ein metalli­ sches Gehäuse 1 auf, in das von oben eine Leiterplatte 2 eingeschoben werden kann. Die Leiterplatte 2 trägt ein ela­ stisches Element 3 als Federmittel, das beim Einschieben an einer metallischen Platte 4 des Gehäuses 1 dicht mit elek­ trischem Kontakt anliegt. Das elastische Element 3 ist spritztechnisch in ein Kunststoffsteckerteil 6 integriert. An electrical device according to the figure has a metallic housing 1 into which a circuit board 2 can be inserted from above. The circuit board 2 carries an ela-elastic element 3 as a spring means which bears tightly with electrical contact when inserted on a metallic plate 4 of the housing 1 . The elastic element 3 is integrated into a plastic plug part 6 by injection molding.

Zur Herstellung einer optimalen EMV-Anbindung der Leiter­ platte 2 an das Gehäuse 1 ist das elastische Element 3 mit der Masse der Leiterplatte 2, beispielsweise durch galva­ nisch aufgebrachte leitende Oberflächen auf der Leiterplat­ te 2 im Bereich des elastischen Elements 3, verbunden. Die metallische Platte 4 ist eine Magnethalteplatte für einen Druckregelbaustein 5 und ist mittels einer Schraube 7 eben­ falls elektrisch leitend mit dem Gehäuse 1 verbunden.To produce an optimal EMC connection of the printed circuit board 2 to the housing 1 , the elastic element 3 is connected to the mass of the printed circuit board 2 , for example by galvanically applied conductive surfaces on the printed circuit board 2 in the area of the elastic element 3 . The metallic plate 4 is a magnetic holding plate for a pressure regulating module 5 and is also electrically connected to the housing 1 by means of a screw 7 .
