Description

Technisches GebietTechnical area

Die Erfindung betrifft ein Aufnahmegehäuse für ein Handwerkzeuggerät, der im Oberbegriff des Patentanspruchs 1 genannten Art.The invention relates to a receiving housing for a hand tool, referred to in the preamble of claim 1. Art.

Stand der TechnikState of the art

Zur Steuerung eines Handwerkzeuggerätes, wie z. B. eines Bohr- oder Meisselhammers, einer Kreis-, Stichsäge, eines Schleifers, eines Schraubers oder dergleichen, werden Elektronikeinrichtungen in einem Aufnahmegehäuse vorgesehen. Ein solches Aufnahmegehäuse umfasst ein erstes eine Öffnung aufweisendes Gehäuseteil und ein zweites Gehäuseteil zum Verschliessen der Öffnung, wobei die Gehäuseteile einen Aufnahmeraum ausbilden. In dem ersten Gehäuseteil ist eine mit Elektronikbauteilen bestückte Platine in einem Abstand zu der Öffnung angeordnet.To control a hand tool, such. As a drill or chisel hammer, a circular, jigsaw, a grinder, a screwdriver or the like, electronic devices are provided in a receiving housing. Such a receiving housing comprises a first housing part having a opening and a second housing part for closing the opening, wherein the housing parts form a receiving space. In the first housing part, a board equipped with electronic components is arranged at a distance from the opening.

Aus der CH 665 150 A5 ist ein Aufnahmegehäuse für ein Elektrohandwerkzeug bekannt, das ein erstes wannenförmiges, eine Öffnung aufweisendes Gehäuseteil umfasst, in dem eine mit Elektronikbauteilen, wie bspw. Steuerungskomponenten, optische Anzeigeelemente oder Stecker, bestückte Platine in einem Abstand zu der Öffnung angeordnet ist. Zum Schutz der Platine ist die Öffnung im ersten Gehäuseteil mit einem als zweiter Gehäuseteil ausgebildete Abdeckplatte abgedeckt, die über einen Rastmechanismus an dem ersten Gehäuseteil festgelegt ist. Die Abdeckplatte ist zumindest in dem Bereich der optischen Anzeigeelemente durchsichtig oder durchscheinend, so dass der Lichtschein derselben visuell wahrnehmbar ist.From the CH 665 150 A5 a receptacle housing for an electric hand tool is known, which comprises a first trough-shaped housing part having an opening, in which a printed circuit board equipped with electronic components, such as control components, optical display elements or plugs, is arranged at a distance from the opening. To protect the board, the opening in the first housing part is covered with a cover formed as a second housing part, which is fixed via a latching mechanism on the first housing part. The cover plate is transparent or translucent, at least in the region of the optical display elements, so that the light emission thereof is visually perceptible.

Nachteilig an der bekannten Lösung ist, dass zwischen dem ersten und zweiten Gehäuseteil Feuchtigkeit oder Staub in den Aufnahmeraum eindringen kann, was zu einer Fehlfunktion der Elektronik führt.A disadvantage of the known solution is that between the first and second housing part moisture or dust can penetrate into the receiving space, resulting in a malfunction of the electronics.

Um solche Aufnahmegehäuse vor äusseren Einflüssen, insbesondere vor dem Eindringen von Feuchtigkeit oder Staub in den Aufnahmeraum zu schützen, wird der Aufnahmeraum nach dem Zusammenführen der Gehäuseteile mit einer Vergussmasse gefüllt.In order to protect such receiving housing from external influences, in particular from the penetration of moisture or dust into the receiving space, the receiving space is filled after merging the housing parts with a potting compound.

Nachteilig an der bekannten Lösung ist, dass von der Aussenseite des Gerätes visuell wahrnehmbare oder mechanisch zugängliche Elektronikbauteile ebenfalls vollständig eingegossen werden.A disadvantage of the known solution is that from the outside of the device visually perceptible or mechanically accessible electronic components are also completely poured.

Darstellung der ErfindungPresentation of the invention

Aufgabe der Erfindung ist es, ein Aufnahmegehäuse der genannten Art zu schaffen, bei der einzelne Elektronikbauteile visuell von der Aussenseite des Gerätes wahrnehmbar oder mechanisch zugänglich sind, wobei der Aufnahmeraum zum Schutz der Elektronik vergiessbar ist.The object of the invention is to provide a receiving housing of the type mentioned, in which individual electronic components are visually perceptible or mechanically accessible from the outside of the device, wherein the receiving space to protect the electronics is pourable.

Die Aufgabe ist durch die Merkmale des unabhängigen Anspruchs gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen dargelegt.The object is solved by the features of the independent claim. Advantageous developments are set forth in the subclaims.

Gemäss der Erfindung ist an dem zweiten Gehäuseteil zumindest ein Hülsenabschnitt vorgesehen, dessen freie axiale Länge zumindest dem Abstand zwischen der Platine und der Öffnung entspricht.According to the invention, at least one sleeve section is provided on the second housing part, the free axial length of which corresponds at least to the distance between the circuit board and the opening.

Der zumindest eine Hülsenabschnitt ist derart an dem zweiten Gehäuseteil angeordnet, dass beispielsweise ein auf der Platine angeordnetes optisches Anzeigeelement visuell von aussen wahrnehmbar beziehungsweise ein auf der Platine angeordneter Stecker von aussen mechanisch zugänglich ist. Die axiale Erstreckung des zumindest einen Hülsenabschnitts ist derart gewählt, dass nach dem Zusammenführen der Gehäuseteile zumindest das freie Ende des freien Endbereichs des Hülsenabschnitts an die Seite der Platine angepresst wird, wobei die umlaufende Dichtzone geschaffen wird. Der verbleibende Raum des Aufnahmeraums wird nach dem Zusammenführen der beiden Gehäuseteile mit einer geeigneten Vergussmasse verfüllt, wobei die umlaufende Dichtzone ein Eintreten der Vergussmasse in den von dem zumindest einen Hülsenabschnitt geschaffenen Innenraum und somit dem in dem Innenraum vorhandenen Elektronikbauteilen verhindert.The at least one sleeve section is arranged on the second housing part such that, for example, an optical display element arranged on the circuit board is visually perceptible from the outside or a plug arranged on the circuit board is mechanically accessible from the outside. The axial extension of the at least one sleeve portion is selected such that after merging the housing parts, at least the free end of the free end portion of the sleeve portion is pressed against the side of the board, wherein the circumferential sealing zone is provided. The remaining space of the receiving space is filled after the merging of the two housing parts with a suitable potting compound, wherein the circumferential sealing zone prevents entry of the potting compound in the created by the at least one sleeve portion interior and thus the existing electronic components in the interior.

Vorzugsweise ist eine Zugangsöffnung zu dem von dem zumindest einen Hülsenabschnitt gebildeten Innenraum in dem zweiten Gehäuseteil vorgesehen, durch die ein an der Platine angeordnetes Elektronikbauteil, wie beispielsweise ein Stecker, von aussen mechanisch zugänglich ist. Bei einem visuell wahrnehmbaren Elektronikbauteil, wie beispielsweise ein LED, ist die Zugänglichkeit des Elektronikbauteils nicht zwingend erforderlich, sofern das zweite Gehäuseteil zumindest in dem Bereich des zumindest einen Hülsenabschnitts transparent oder zumindest durchscheinend ausgebildet ist.Preferably, an access opening to the interior formed by the at least one sleeve portion in the second housing part is provided, through which an electronic component arranged on the circuit board, such as a plug, is mechanically accessible from the outside. In a visually perceptible electronic component, such as an LED, the accessibility of the electronic component is not mandatory, if the second housing part is at least in the region of the at least one sleeve portion transparent or at least translucent.

Bevorzugt ist zumindest der freie Endbereich des zumindest einen Hülsenabschnitts aus einem elastisch verformbaren Material gefertigt, womit sich das freie Ende beim Zusammenführen der beiden Gehäuseteile leicht zurückstülpt und dabei eine sichere Abdichtung zwischen dem Aufnahmeraum und der Platine und somit gegen den von dem zumindest einen Hülsenabschnitt geschaffenen Innenraum gewährleistet. Beispielsweise kommt als elastisch verformbares Material ein Elastomer zur Anwendung. Alternativ ist der ganze zumindest eine Hülsenabschnitt oder sogar der gesamte zweite Gehäuseteil aus einem elastisch verformbaren Material gefertigt.Preferably, at least the free end portion of the at least one sleeve portion is made of an elastically deformable material, whereby the free end easily slips back when merging the two housing parts, while a secure seal between the receiving space and the board and thus created by the at least one sleeve portion Interior guaranteed. For example, an elastomer is used as the elastically deformable material. Alternatively, the whole at least one sleeve portion or even the entire second housing part is made of an elastically deformable material.

Vorzugsweise weist der zumindest eine Hülsenabschnitt einen umfangseitig angeordneten Hinterschnitt auf. Der Hinterschnitt ist vorteilhaft auf die Ausgestaltung des freien Randes des ersten Gehäuseteils abgestimmt ausgebildet und ermöglicht eine einfache Festlegung des zweiten Gehäuseteils an dem ersten Gehäuseteil über eine Rastverbindung. Diese Rastverbindung hält die beiden Gehäuseteile auch während dem Verfüllen des verbleibenden Aufnahmeraums mit der Vergussmasse in Position und dichtet die Öffnung im ersten Gehäuseteil sowie den Innenraum gegen den Austritt der Vergussmasse aus dem Aufnahmeraum ab.The at least one sleeve section preferably has an undercut arranged on the circumference. The undercut is advantageously formed tuned to the configuration of the free edge of the first housing part and allows easy fixing of the second housing part to the first housing part via a latching connection. This locking connection holds the two housing parts during filling of the remaining receiving space with the potting compound in position and seals the opening in the first housing part and the interior against the escape of the potting compound from the receiving space.

Bevorzugt ist der zumindest eine Hülsenabschnitt in seinem freien Endbereich trichterförmig erweiternd ausgebildet, so dass beim Zusammenführen der beiden Gehäuseteile der freie Endbereich des zumindest einen Hülsenabschnitts für eine sichere Abdichtung zur Platine nach aussen gestülpt wird und zumindest bereichsweise flächig an der Seite der Platine anliegt.Preferably, the at least one sleeve portion is funnel-shaped widening in its free end, so that when merging the two housing parts of the free end portion of the at least one sleeve portion for a secure seal to the board is pushed outwards and at least partially rests flat against the side of the board.

Vorzugsweise ist die Wandstärke des zumindest einen Hülsenabschnitts zum freien Ende hin abnehmend ausgebildet, so dass sich der freie Endbereich beim Zusammenführen der beiden Gehäuseteile leicht verformen lässt und sich einfach an die Platine unter Vorspannung anlegt.Preferably, the wall thickness of the at least one sleeve portion is designed to be decreasing towards the free end, so that the free end region can easily be deformed when the two housing parts are brought together and simply applies to the printed circuit board under prestressing.

Wege zur Ausführung der ErfindungWays to carry out the invention

Das in den Figuren 1 bis 3 dargestellte Aufnahmegehäuse 11 für ein, hier nicht dargestelltes Handwerkzeuggerät, umfasst ein wannenförmiges, erstes Gehäuseteil 13, das eine als Langloch ausgebildete Öffnung 15 aufweist, und ein zweites Gehäuseteil 14 zum Verschliessen der Öffnung 15, wobei die Gehäuseteile 13, 14 einen Aufnahmeraum 16 ausbilden. In dem ersten Gehäuseteil 13 ist eine mit Elektronikbauteilen 17, mit LEDs 18 und mit einem Stecker 19 bestückte Platine 20 in einem Abstand A zu der Öffnung 15 angeordnet.The receiving housing 11 shown in Figures 1 to 3 for a, not shown here hand tool, comprises a trough-shaped, first housing part 13 having a slot formed as an opening 15, and a second housing part 14 for closing the opening 15, wherein the housing parts , 14 form a receiving space 16. In the first housing part 13, a board 20 equipped with electronic components 17, with LEDs 18 and with a plug 19 is arranged at a distance A from the opening 15.

An dem zweiten Gehäuseteil 14 sind drei Hülsenabschnitte 26 vorgesehen, deren freie axiale Länge L grösser als der Abstand A zwischen der Platine 20 und der Öffnung 15 ausgebildet. Da die freie axiale Länge L der Hülsenabschnitte 26 zumindest dem Abstand A entspricht, liegen die freien Endbereiche 28 der Hülsenabschnitte 26 unter Ausbildung von drei Innenräumen 27 im zusammengefügten Zustand des ersten Gehäuseteils 13 und des zweiten Gehäuseteils 14 an der Seite 21 der Platine 20 über eine umlaufende Dichtzone an und dichten den Aufnahmeraum 16 zu den Innenräumen 27 ab. In dem zweiten Gehäuseteil 14 sind jeweils Zugangsöffnungen 29 zu den Innenräumen 27 vorgesehen, so dass die in den Innenräumen 27 zu liegen kommenden LEDs 18 von aussen visuell wahrnehmbar und der Stecker 19 von aussen mechanisch zugänglich ist.On the second housing part 14, three sleeve sections 26 are provided, the free axial length L greater than the distance A between the board 20 and the opening 15 is formed. Since the free axial length L of the sleeve portions 26 at least equal to the distance A, the free end portions 28 of the sleeve portions 26 are to form three interiors 27 in the assembled state of the first housing part 13 and the second housing part 14 on the side 21 of the board 20 via a circumferential sealing zone and seal the receiving space 16 to the interior 27 from. Access openings 29 to the interior spaces 27 are respectively provided in the second housing part 14, so that the LEDs 18 coming to lie in the interior spaces 27 are visually perceptible from the outside and the plug 19 is mechanically accessible from the outside.

Der freie Endbereich 28 der Hülsenabschnitte 26 ist aus einem Elastomermaterial gefertigt und erweitert sich trichterförmig, wobei die Wandstärke der Hülsenabschnitte 26 zum freien Ende hin abnehmend ausgebildet ist. Im vorliegenden Ausführungsbeispiel weisen die Hülsenabschnitte 26 in deren axialen Erstreckung eine hyperbolische Aussenkontur auf.The free end portion 28 of the sleeve portions 26 is made of an elastomeric material and widens funnel-shaped, wherein the wall thickness of the sleeve portions 26 is formed to the free end decreasing. In the present exemplary embodiment, the sleeve sections 26 have a hyperbolic outer contour in their axial extent.

Zur Ausbildung eines Hinterschnitts 31 weisen die Hülsenabschnitte 26 eine umfangseitig angeordnete Vertiefung auf, die entsprechend der Ausgestaltung des freien Randes 32 des ersten Gehäuseteils 13 ausgebildet ist. Über die von dem Hinterschnitt 31 geschaffene Rastverbindung wird der zweite Gehäuseteil 14 und somit der freie Endbereich 28 der Hülsenabschnitte 26 beim Verfüllen des Aufnahmeraums 16 mit der Vergussmasse 23 durch die Einfüllöffnung 22 im ersten Gehäuseteil 13 mit der Seite 21 der Platine 20 in Anlage gehalten.
