Preferably, the connection is made materially, preferably by the leaf spring forms an integral part of a protruding at the edge of the housing opening collar portion.

[25] Die Blattfeder ist vorzugsweise zur Gehäuseöffnung hin gewölbt oder geknickt. Sie weist vorzugsweise eine Wölbung in die Gehäuseöffnung hinein auf. Der Grad der Wölbung bzw. der in eine Grundfläche der Öffnung hineinragende Überstand nimmt vorzugsweise längs der Montagerichtung zu.

[29] Vorzugsweise ist alternativ oder zusätzlich zur Torsionskomponente ein Mittelbereich der Blattfeder relativ zu den beiden Enden der Blattfeder auslenkbar. Drehpunkte sind dabei die Blattfederenden. Das Drehmoment wirkt in der Ebene der Abdeckung. Preferably, alternatively or in addition to the torsion component, a central region of the leaf spring is deflectable relative to the two ends of the leaf spring. Fulcrums are the leaf spring ends. The torque acts in the plane of the cover.
[30] Die für den kragenartig überstehenden Gehäuseabschnitt erforderliche Bauhöhe h2 ist deutlich geringer als die Bauhöhe h1 , die mit Federzungen 4,5 nach dem Stand der Technik erforderlich wäre. Denn die Wirkrichtung der Blattfeder ist um 90° relativ zu solchen Federzungen in eine Ebene parallel zur Abdeckung gedreht. Dadurch wird der benötigte Federweg parallel zur Abdeckung ausgeführt und ist in Montagerichtung reduziert. Außerdem ist die erforderliche Auslenkung geringer, weil die Federkraft durch beidseitige Lagerung bzw. Befestigung der Feder doppelt wirkt und durch zusätzliche Torsion der Blattfeder verstärkt ist. Im Ergebnis ergibt sich so eine Bauraum-Ersparnis und eine zuverlässigere Befestigung und eine erhöht die Stabilität der Blattfeder. The required for the collar-like protruding housing portion height h2 is significantly less than the height h1, which would be required with spring tongues 4.5 according to the prior art. Because the effective direction of the leaf spring is rotated by 90 ° relative to such spring tongues in a plane parallel to the cover. As a result, the required travel is performed parallel to the cover and is reduced in the mounting direction. In addition, the required deflection is lower because the spring force acts double by both sides storage or attachment of the spring and is reinforced by additional torsion of the leaf spring. As a result, this results in a space savings and a more reliable attachment and increases the stability of the leaf spring.
