Description

Die vorliegende Erfindung betrifft ein Kunststoffgehäuse, bestehend aus einer unteren und einer oberen Gehäusehälfte, wobei die beiden Gehäusehälften über Schraubdome miteinander verbunden sind.The The present invention relates to a plastic housing consisting of a lower one and an upper shell half, wherein the two housing halves via screw domes connected to each other.

Gehäuseteile aus Kunststoff werden im Allgemeinen mit selbstschneidenden Schrauben verschraubt. Als Aufnahme für die Schraube werden an den Kunststoffteilen so genannte Schraubdome angebracht. Dabei handelt es sich um schlanke, meist mit kreisrundem Querschnitt ausgeführte Zylinder mit einer Bohrung an der Stirnseite, um den Schraubenschaft aufzunehmen. Beim Einschrauben der Schraube wird der Schraubdom aufgrund des dadurch einwirkenden Drehmoments ein wenig tordiert. Mit zunehmender Länge nimmt die Verdrehung des Schraubdoms zu und damit auch die mechanische Belastung.housing parts Plastic are generally made with self-tapping screws screwed. As a recording for The screws are called on the plastic parts so-called screw domes appropriate. These are slender, usually circular Cross-section executed Cylinder with a hole on the front side, around the screw shaft take. When screwing in the screw, the screw dome a little twisted due to the torque acting thereby. With increasing length increases the rotation of the screw and thus the mechanical stress.

Im Allgemeinen wird versucht, die Schraubdome durch Stege zu versteifen oder die Wanddicke so zu erhöhen, dass die mechanische Belastung am Grund einen zulässigen Wert erreicht. Diese Lösung erfordert aber einen erhöhten Platzbedarf für die Schraubdome, welcher nicht immer gegeben ist.in the In general, an attempt is made to stiffen the screw domes by webs or to increase the wall thickness so that the mechanical load on the ground is a permissible value reached. This solution requires but an increased Space required for the screw dome, which is not always given.

Aufgabe der vorliegenden Erfindung, ist es für ein Kunststoffgehäuse der eingangs genannten Art eine Lösung mit Schraubdomen anzugeben, welche keinen zusätzlichen Platzbedarf benötigt.task of the present invention, it is for a plastic housing of initially mentioned kind a solution specify with screw domes, which does not require additional space.

Die erfindungsgemäße Lösung ist für das eingangs genannte Kunststoffgehäuse dadurch gekennzeichnet, dass die Schraubdome zur Aufnahme der Schrauben und die Dome zur Durchführung der Schrauben an ihren freien Enden formschlüssige Endbereiche aufweisen.The inventive solution for the beginning called plastic housing characterized in that the screw domes for receiving the screws and the cathedrals to carry the screws have positive end portions at their free ends.

Durch das Anbringen einer formschlüssigen Verbindung zwischen den beiden Domen der beiden Gehäusehälften werden die Schraubdome an ihren freien Enden abgestützt und dadurch ein Tordieren der Schraubdome verhindert.By the attachment of a positive connection between the two domes of the two housing halves are the screw domes supported at their free ends and thereby prevents twisting of the screw domes.

Der Vorteil der erfindungsgemäßen Lösung liegt darin, dass es zu einer geringeren Torsion der Schraubdome kommt und dass durch die niedrigen Wandstärken und durch die nicht benötigten Stege nur ein geringerer Platzbedarf benötigt wird.Of the Advantage of the invention is solution in that there is less torsion of the screw domes and that due to the low wall thicknesses and the unnecessary bridges only a smaller footprint needed becomes.

Ein zusätzlicher Vorteil ergibt sich dadurch, dass die beiden Gehäusehälften durch die Formschlüsse vorpositioniert werden, wodurch die Schrauben leichter in die für sie vorgegebene Bohrung finden.One additional Advantage results from the fact that the two housing halves prepositioned by the form-fitting which makes it easier for the screws to find their way into the hole

Weitere zweckmäßige Ausgestaltungen der vorliegenden Erfindung ergeben sich aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der beigefügten Zeichnung.Further expedient embodiments The present invention will become apparent from the dependent claims and from the following description of an embodiment with reference to the attached Drawing.

Wie aus den Figuren zu erkennen ist, gehören jeweils der Schraubdom 3 und der Dom 5 und der Schraubdom 4 und der Dom 6 zusammen. Der Schraubdome 3 und der Dom 5 sind in ihren Endbereichen in zwei Teile aufgeteilt, wobei sich zwischen diesen beiden Teilen eine Abstützungsfläche 7 ausbildet.As can be seen from the figures, each include the screw dome 3 and the dome 5 and the screw dome 4 and the dome 6 together. The screw dome 3 and the dome 5 are divided in their end regions into two parts, with a support surface between these two parts 7 formed.

Bei größeren Schraubdomen kann in den Endbereichen eine Verzahnung mittels des Prinzips einer Klauenkupplung vorgesehen werden, wie es bei dem Schraubdom 4 und dem Dom 6 dargestellt ist.For larger Schraubdomen a toothing can be provided by means of the principle of a dog clutch in the end regions, as in the Schraubdom 4 and the cathedral 6 is shown.
