Abstract

Zur Sicherstellung der Entformbarkeit von aus Gehäuseschalenhälften (3) bestehenden Gehäusen von Geräten mit einer Tastaturmatte (2), beispielsweise von Mobilteilen von Schnurlostelefonen oder von Mobiltelefonen, wird für die betreffenden Geräte eine Tastaturmatte (2) mit integrierten Abdichtrippen (10) vorgeschlagen. Die integrierten Abdichtrippen (10) ersetzen ansonsten an den Gehäuseschalenhälften (3) vorhandene Rippenteile (4), die auf die Tastaturmatte (2) drücken und dadurch eine Abdichtung zum Inneren des betreffenden Geräts bewirken. Durch den wenigstens teilweisen Wegfall der Rippenteile (4) an den Gehäuseschalenhälften (3) werden Schrägausstoßer (5) an der einen Gehäuseschalenhälfte (3), die Hinterschnitte (7) an der anderen Gehäuseschalenhälfte im montierten Zustand hintergreifen und so die Gehäuseschalenhälften (3) zusammenhalten, bei einer Entformung an einer Entformung nicht mehr gehindert. Die Abdichtung zum Gehäuseinneren ist aber nach wie vor gegeben.

Figure 00000001
To ensure the demouldability of housing shell halves (3) existing housings of devices with a keypad (2), for example, from handsets of cordless telephones or mobile phones, a keypad mat (2) with integrated sealing ribs (10) is proposed for the devices concerned. The integrated sealing ribs (10) otherwise replace the housing shell halves (3) ribbed parts (4) which press on the keypad mat (2), thereby causing a seal to the interior of the device in question. As a result of the at least partial removal of the rib parts (4) on the housing shell halves (3), oblique ejectors (5) on one housing shell half (3) engage behind the undercuts (7) on the other housing shell half in the assembled state and thus hold together the housing shell halves (3) , no longer hindered in demoulding at a demolding. The seal to the housing interior is still given.
