Abstract
Description
Die Erfindung betrifft ein Gehäuse nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a housing according to the preamble of patent claim 1.
Solche Gehäuse werden insbesondere für einen elektronischen Schlüssel, einen Identifikations(ID)-Geber o. dgl. eines Schließsystems in einem Kraftfahrzeug verwendet.Such housings are used in particular for an electronic key, an identification (ID) sensor o. The like. Of a locking system in a motor vehicle.
Schließsysteme für Kraftfahrzeuge sind zur Steigerung des Komforts für den Benutzer oft mit einem elektronischen Schlüssel ausgestattet. Nach entsprechender Betätigung durch den Benutzer wird zwischen dem Schlüssel und einem Steuergerät im Kraftfahrzeug ein Code, beispielsweise über elektromagnetische Wellen, ausgetauscht, so dass nach positiver Auswertung des Codes die Türen, der Kofferraumdeckel o. dgl. des Kraftfahrzeugs fernbedienbar ent- und/oder verriegelt sowie sonstige Funktionen ausgelöst werden.Automotive locking systems are often equipped with an electronic key to enhance user comfort. After appropriate operation by the user code between the key and a control unit in the motor vehicle, for example, via electromagnetic waves, exchanged, so that after positive evaluation of the code, the doors, the boot lid o. The like. Of the motor vehicle remote controllable ent and / or locked as well as other functions are triggered.
Ein derartiger elektronischer Schlüssel ist aus der
Der Erfindung liegt die Aufgabe zugrunde, das Gehäuse derart weiterzuentwickeln, dass die Leiterplatte weitgehend vor Zerstörung, insbesondere beim Herunterfallen des Schlüssels, geschützt ist. Insbesondere soll die Leiterplatte in einem Fahrzeugschlüssel so fixiert werden, dass die Fixierung spielfrei ausgeführt wird und/oder die Toleranzen der Einzelteile ausgeglichen werden. Bevorzugterweise soll desweiteren die Fixierung falltesttauglich sein.The invention has for its object to further develop the housing so that the circuit board is largely protected against destruction, especially when the key falls down. In particular, the circuit board should be fixed in a vehicle key so that the fixation is performed without play and / or the tolerances of the items are compensated. Preferably, furthermore, the fixation should be falltesttauglich.
Diese Aufgabe wird bei einem gattungsgemäßen Gehäuse durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved in a generic housing by the characterizing features of claim 1.
Beim erfindungsgemäßen Gehäuse ist die Leiterplatte mittels wenigstens eines in dem einen Gehäuseteil befindlichen Fixierelements vorpositioniert. Weiter ist die Leiterplatte mittels wenigstens eines in dem einen Gehäuseteil befindlichen Halteelements seitlich geklemmt. Geschaffen ist somit eine Fixierung der Leiterplatte in einem Fahrzeugschlüssel. Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.In the case of the invention, the printed circuit board is prepositioned by means of at least one fixing element located in the one housing part. Furthermore, the printed circuit board is clamped laterally by means of at least one retaining element located in the one housing part. Created is thus a fixation of the circuit board in a vehicle key. Further embodiments of the invention are the subject of the dependent claims.
Zur weiteren Steigerung der Robustheit ist die Leiterplatte mittels wenigstens eines in dem anderen Gehäuseteil befindlichen elastischen Niederhalters, insbesondere zum Ausgleich von Dickentoleranzen, fixiert.To further increase the robustness, the printed circuit board is fixed by means of at least one elastic hold-down located in the other housing part, in particular to compensate for thickness tolerances.
In einer weiteren Ausgestaltung können das Fixierelement sowie das Halteelement im Gehäuseunterteil befindlich sein. Der Niederhalter kann dann im Gehäuseoberteil befindlich sein. In einer anderen Ausgestaltung können das Fixierelement sowie das Halteelement im Gehäuseoberteil befindlich sein. Der Niederhalter kann dann im Gehäuseunterteil befindlich sein.In a further embodiment, the fixing element and the retaining element may be located in the lower housing part. The hold-down can then be located in the upper housing part. In another embodiment, the fixing element and the retaining element may be located in the upper housing part. The hold-down can then be located in the housing base.
In einfacher Ausgestaltung kann es sich bei dem Fixierelement um einen Stift, einen Steg, eine Rippe o. dgl. handeln. Bei dem Halteelement kann es sich um eine Einreitrippe, ein elastisches und/oder federndes Element, eine Bohrung, eine Nut o. dgl. handeln. In kostengünstiger Weise kann der Niederhalter aus einem thermoplastischen Kunststoff bestehen.In a simple embodiment, the fixing element may be a pin, a web, a rib or the like. The holding element may be a Einreitrippe, an elastic and / or resilient element, a bore, a groove o. The like. Act. In a cost effective manner, the hold-down can consist of a thermoplastic material.
Für eine besonders bevorzugte Ausgestaltung ist nachfolgendes festzustellen. Die Leiterplatte wird über zwei Stifte vorpositioniert und über Einreitrippen in X- und Y-Richtung geklemmt. Die Dickentoleranz wird durch weiche, thermoplastische Niederhalter am Oberteil ausgeglichen. Im Unterteil liegt die Leiterplatte fest auf.For a particularly preferred embodiment is to be determined below. The printed circuit board is pre-positioned over two pins and clamped in the X and Y direction via ribs. The thickness tolerance is compensated by soft, thermoplastic hold-down on the upper part. In the lower part of the circuit board is firmly on.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass eine falltesttaugliche Leiterplattenklemmung ohne zusätzliche Verschraubung und/oder Verstemmung mit Toleranzausgleich erreicht ist. Vorteilhafterweise ist die Herstellung des Schlüssels voll automatisierbar.The advantages achieved by the invention are in particular that a falltesttaugliche PCB clamping is achieved without additional screw and / or caulking with tolerance compensation. Advantageously, the production of the key is fully automated.
