Schnittstellenelemente, unter denen auch Schnittstellenbau- gruppen zu subsumieren sind, werden für die unterschiedlichsten Funktionen in Elektrogeräten eingesetzt. Sie kommen überall dort zur Anwendung, wo zwei Teile, nämlich das Schnittstellenelement und eine Schnittstellenelementaufnähme aufeinander bzw. ineinander gebracht werden. Häufig han- delt es sich bei einem Schnittstellenelement um einen Batteriefachdeckel zum Verschließen eines Batteriefachs (Schnittstellenelementaufnähme) eines Elektrogerätes oder um eine (elektrische) Schnittstelle zwischen einem Batteriefach und einem elektrischen Antrieb oder einer Elektro- nik. Derartige Schnittstellenelemente weisen üblicherweise elektrische Kontakte auf, die an dem aus Hartkunststoff ausgebildeten Schnittstellenelement, meist durch Umsprit- zen, festgelegt sind. Neben oder anstelle einer elektrischen Kontaktierung können bekannte Schnittstellenelemente die unterschiedlichsten Funktionen erfüllen und hierzu beispielsweise Kodierrippen, Führungsrippen, Anschlagsrippen, etc. aufweisen. In der Praxis erfordern Schnittstellenpartner (Schnittstellenelement und Schnittstellenelementaufnähme) eine genaue Toleranzeinhaltung zueinander, um die Schnittstellenpartner relativ zueinander exakt positionieren zu können.Interface elements, which also include interface modules, are used for a wide variety of functions in electrical appliances. They are used wherever two parts, namely the interface element and an interface element receptacle are brought together or into one another.

Bei bekannten Schnittstellenpartnern erfolgt die Positionierung entweder möglichst spielfrei oder mit einem definierten Spiel, also schwimmend. Bei der spielfreien Positionierung soll eine möglichst genaue Passung erreicht wer- den. Bei der schwimmenden Positionierung soll dem Schnittstellenelement hingegen die Möglichkeit gegeben werden, sich relativ zur Schnittstellenelementaufnähme zu bewegen, beispielsweise um Toleranzabweichungen auszugleichen oder Vibrationsverschiebungen zuzulassen.

In backlash-free positioning, the most accurate fit possible. In the floating positioning, however, the interface element is to be given the opportunity to move relative to the interface element receiving means, for example to compensate for tolerance deviations or to allow vibration shifts. In the known floating positioning there is the option that

Alternativ ist eine nicht federnde, also frei schwimmende Positionierung der Schnittstellenpartner zueinander möglich.Interface element by mechanical, formed of rigid material, spring elements to make resilient, so to realize a floating bearing with nominal position and restoring forces. Alternatively, a non-resilient, so free-floating positioning of the interface partners to each other possible.
Nachteilig bei schwimmend relativ zueinander positionierbaren Schnittstellenpartnern ist, dass diese in der Regel ei- ne mangelnde Verschmutzungsresistenz aufweisen, wodurch die Relativverstellmöglichkeit zwischen den Schnittstellenpartnern im Laufe der Zeit verloren geht, mit dem Resultat, dass die Schnittstellenpartner ihre Funktion nicht mehr hinreichend erfüllen können. Bei einer festen, spielfreien Positionierung ist wiederum von Nachteil, dass überhaupt keine Anpassung der Schnittstellenpartner relativ zueinander möglich ist, sodass der Anwendungsbereich einer spielfreien Positionierung begrenzt ist. Allgemein haben sämtliche bekannten Schnittstellenpartner den Nachteil, dass stoßartige Belastungen von Hartkomponen- tenabschnitten aufgenommen werden, und, insbesondere bei dauerhafter Belastung, zu Bruch oder anderen Beschädigungen führen .One disadvantage of floating interface partners that can be positioned relative to one another is that they generally have a lack of contamination resistance, as a result of which the relative adjustment possibility between the interface partners is lost over time, with the result that the interface partners can no longer sufficiently fulfill their function. With a fixed, backlash-free positioning is again disadvantageous that no adaptation of the interface partners is possible relative to each other, so that the scope of a play-free positioning is limited. In general, all known interface partners have the disadvantage that shock-like loads are absorbed by hard component sections and, in particular under permanent load, lead to breakage or other damage.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. In den Rahmen der Erfindung fallen sämtliche Kombinationen aus zumindest zwei von in der Beschreibung, den Ansprüchen und/oder den Figuren offenbarten Merkmalen.This object is achieved with regard to the interface element having the features of claim 1, with regard to the interface element receptacle having the features of claim 6, with regard to the electrical device having the features of claim 10 and by a use according to claim 11. Advantageous developments of the invention are specified in the subclaims.

Der Erfindung liegt der Gedanke zugrunde, einen Positionierabschnitt aus einem elastischen Material vorzusehen, der ein Relativverschieben des Hartkomponentenabschnittes des Schnittstellenelementes relativ zur Schnittstellenele- mentaufnähme ermöglicht. Dabei liegt es im Rahmen der Erfindung, den Positionierabschnitt am Schnittstellenelement und/oder an der Schnittstellenelementaufnähme zu realisieren. Wesentlich ist es lediglich, dass der Positionierabschnitt aus einem elastischeren (weicheren) Material ausgebildet ist als der Hartkomponentenabschnitt des Schnittstellenelementes. Anders ausgedrückt besteht die Erfindung darin, zwischen dem Hartkomponentenabschnitt des Schnittstellenelementes und einem Hartkomponentenabschnitt der Schnittstellenelementaufnähme einen aus einem elastischen Material ausgebildeten Positionierabschnitt vorzusehen, der durch eigenes elastisches Verformen eine Relativbewegung zwischen den beiden Hartkomponentenabschnitten der Schnittstellenpartner zulässt. Durch die Ausbildung des Positionierabschnittes aus einem elastischen Material ist bevorzugt eine Relativbewegung des Hartkomponentenabschnittes des Schnittstellenelementes zur Schnittstellenelementauf- nähme entlang sämtlicher Raumachsen möglich. Zusätzlich ermöglicht der elastische Positionierabschnitt mit Vorteil zusätzlich eine Verschwenkbewegung des Hartkomponentenabschnittes um mindestens eine, vorzugsweise um sämtliche drei, Raumachsen. Ein nach dem Konzept der Erfindung ausge- bildetes Schnittstellenelement bzw. eine nach dem Konzept der Erfindung ausgebildete Schnittstellenelementaufnähme kombiniert ausschließlich die Vorteile einer spielfreien und einer schwimmenden Positionierung und vermeidet deren Nachteile. So ist zum einen eine exakte Relativpositionie- rung der Schnittstellenpartner zueinander möglich und gleichzeitig wird die Verschmutzungsresistenz erhöht. Anders ausgedrückt wird die Relativbewegungsfunktion des Positionierabschnittes durch über die Lebensdauer auftretende Verschmutzungen nicht eingeschränkt, da die Relativbewegung zwischen dem mindestens einen Hartkomponentenabschnitt des Schnittstellenelementes und dem mindestens einen Hartkomponentenabschnitt der Schnittstellenelementaufnähme nur durch eine (innere) Materialverformung des Positionierabschnittes und nicht durch eine gleitende Relativbewegung realisiert ist. Darüber hinaus wird eine erhöhte mechanische Festigkeit als bei spielfreier und gleitend schwimmender Positionierung realisiert. Ferner wird die mechanische Robustheit, insbesondere die Bruchfestigkeit, aufgrund der Stoßabsorptionsfunktion des Positionierabschnittes erhöht. Insbesondere wird durch den Positionierabschnitt ein verbessertes Dämpfungsverhalten realisiert. Hieraus wiederum resultiert eine verbesserte Vibrationsbeständigkeit als bei bekannten Positionierungen. Darüber hinaus ist die Passgenauigkeit im Vergleich zu bekannten schwimmenden Positionierungen optimiert. Ferner können die einzuhaltenden Toleranzgrenzen aufgrund der Ausbildung des Positionierabschnittes aus einem elastischen Material vergrößert werden.The invention is based on the idea to provide a positioning section made of an elastic material, which permits relative displacement of the hard component portion of the interface element relative to the interface element receiving means. It is within the scope of the invention to realize the positioning section on the interface element and / or on the interface element receiving means. It is only essential that the positioning section is made of a more elastic (softer) material than the hard component section of the interface element. In other words, the invention consists in providing between the hard component section of the interface element and a hard component section of the interface element mounting a positioning section formed of an elastic material which, by its own elastic deformation, permits a relative movement between the two hard component sections of the interface partners. Due to the design of the positioning section made of an elastic material, a relative movement of the hard component section of the interface element for interface element reception along all spatial axes is preferably possible. In addition, the elastic positioning section advantageously additionally allows a pivoting movement of the hard component section about at least one, preferably around all three, spatial axes. An interface element designed according to the concept of the invention or an interface element receptacle designed according to the concept of the invention exclusively combines the advantages of play-free and floating positioning and avoids their disadvantages. On the one hand, exact relative positioning of the interface partners to one another is possible, and at the same time, the resistance to contamination is increased. In other words, the relative movement function of the positioning section is due to over the life occurring Contamination is not limited, since the relative movement between the at least one hard component section of the interface element and the at least one hard component section of the interface element receiver is realized only by an (internal) material deformation of the positioning section and not by a sliding relative movement. In addition, an increased mechanical strength is realized as play-free and slidably floating positioning. Furthermore, the mechanical robustness, in particular the breaking strength, is increased due to the impact absorbing function of the positioning section. In particular, an improved damping behavior is realized by the positioning section. This in turn results in an improved vibration resistance than known positions. In addition, the accuracy of fit compared to known floating positioning is optimized. Furthermore, the tolerance limits to be complied with can be increased due to the formation of the positioning of an elastic material.
Bei der Auslegung des Positionierabschnittes ist darauf zu achten, dass sich die Kennlinien des elastischen Materials im Vergleich zu Federelementen höchst unlinear ausfallen, d.h. es werden geringe Rückstellkräfte nahe der neutralen Stellung und relativ hohe Rückstellkräfte am Ende des ReIa- tivverschiebungsweges erreicht.When designing the positioning section, care must be taken to ensure that the characteristics of the elastic material are highly nonlinear compared to spring elements, i. Low restoring forces near the neutral position and relatively high restoring forces at the end of the displacement displacement path are achieved.
Unter einem Schnittstellenelement im Sinne der Erfindung werden sämtliche Bauteile oder Baugruppen verstanden, die eine funktionelle Schnittstelle zwischen zwei Funktionselementen des Elektrogerätes erfüllen. Bevorzugt handelt es sich bei dem Schnittstellenelement, wie später noch erläutert werden wird, um ein elektrisches Schnittstellenelement mit einem elektrischen Kontakt zum Herstellen einer elektrischen Verbindung zwischen einem Batterie- und/oder Akkumulatorfach und dem eigentlichen Elektrogerät, insbesondere dem mindestens einen Elektromotor und/oder der Elektronik des Elektrogerätes. Dabei liegt es im Rahmen der Erfindung, dass das Schnittstellenelement dauerhaft fest oder lösbar mit der Schnittstellenelementaufnähme verbunden ist. Wesentlich ist, dass im aneinander festgelegten Zustand von Schnittstellenelement und Schnittstellenelementaufnähme und/oder beim Montieren der Schnittstellenpartner eine Relativbewegung des Hartkomponentenabschnittes des Schnittstellenelementes relativ zu einem Hartkomponentenabschnitt der Schnittstellenelementaufnähme ermöglicht wird.Under an interface element in the context of the invention, all components or assemblies are understood to meet a functional interface between two functional elements of the electrical appliance. As will be explained later, the interface element is preferably an electrical interface element with an electrical contact for establishing an electrical connection between a battery and / or accumulator compartment and the actual electrical appliance, in particular the at least one electric motor and / or the electronics of the electrical appliance. It is within the scope of the invention for the interface element to be permanently or detachably connected to the interface element receptacle. It is essential that in the mutually fixed state of the interface element and the interface element receiving means and / or during mounting of the interface partner a relative movement of the hard component section of the interface element relative to a hard component section of the interface element receiving means be made possible.
In Weiterbildung der Erfindung ist mit Vorteil vorgesehen, dass sowohl der Positionierabschnitt als auch der Hartkomponentenabschnitt aus Kunststoff ausgebildet sind, wobei der den Positionierabschnitt bildende Kunststoff bei Raumtemperatur, also bei etwa 200C, weicher ist als das Kunst- Stoffmaterial des Hartkomponentenabschnittes. Besonders geeignet zur Ausbildung des Positionierabschnittes ist Kunststoffelastomermaterial . Besonders bevorzugt ist der Positionierabschnitt aus einem thermoplastischen Elastomermaterial (TPE) ausgebildet.In a further development of the invention is advantageously provided that both the positioning and the hard component portion are formed of plastic, wherein the plastic forming the positioning is at room temperature, ie at about 20 0 C, softer than the plastic material of the hard component section. Particularly suitable for the formation of the positioning is Kunststoffelastomermaterial. Particularly preferably, the positioning section is formed from a thermoplastic elastomer material (TPE).
In Weiterbildung der Erfindung ist mit Vorteil vorgesehen, dass der Positionierabschnitt unmittelbaren Kontakt zum Hartkomponentenabschnitt des Schnittstellenelementes bzw. der Schnittstellenelementaufnähme hat. Hierzu ist es mög- lieh, den Positionierabschnitt als von dem Hartkomponentenabschnitt separates Bauteil auszubilden und die Bauteile aneinander anliegend, vorzugsweise formschlüssig, anzuordnen. Bevorzugt sind jedoch der Positionierabschnitt und der Hartkomponentenabschnitt als unlösbares Verbundbauteil, insbesondere als Mehrkomponentenspritzgussteil, ausgebildet. Bevorzugt handelt es sich um eine Zwei-Komponenten- KunstStoffumspritzung.In a development of the invention, it is advantageously provided that the positioning section has direct contact with the hard component section of the interface element or the interface element receiver. For this purpose, it is possible to form the positioning section as a component separate from the hard component section and to arrange the components adjacent to one another, preferably in a form-locking manner. However, preferred are the positioning and the Hard component portion as insoluble composite component, in particular as a multi-component injection molded part formed. It is preferably a two-component plastic coating.
Von besonderem Vorteil ist eine Ausführungsform des Schnittstellenelementes bzw. der Schnittstellenelementauf- nahme, bei der an dem Hartkomponentenabschnitt des Schnittstellenelementes oder an einem Hartkomponentenabschnitt der Schnittstellenelementaufnähme mindestens ein Funktionsabschnitt festgelegt ist oder aber der Funktionsabschnitt von dem jeweiligen Hartkomponentenabschnitt gebildet ist. So ist es beispielsweise möglich, dass der Hartkomponentenabschnitt mindestens einen elektrischen Kontakt oder mindes- tens eine Kodierrippe und/oder mindestens eine Führungsrippe und/oder mindestens eine Anschlagrippe aufweist oder bildet. Bei einer derartigen Ausführungsform kommen dem Hartkomponentenabschnitt im Wesentlichen harte, statische Funktionen zu, wohingegen dem Positionierabschnitt die wei- chen, dynamischen Funktionen zukommen, insbesondere das Abfangen von Vibrationen und Stößen sowie sonstiger Kräfte und das Garantieren einer Beweglichkeit des Schnittstellenelementes relativ zur Schnittstellenelementaufnähme . Bevorzugt stellt der Positionierabschnitt auch Rückstellkräfte bereit, beispielsweise um an dem Hartkomponentenabschnitt festgelegte Kontakte in Richtung auf eine Batterie oder einen Akkumulator mit einer Federkraft zu beaufschlagen.Of particular advantage is an embodiment of the interface element or of the interface element receptacle, in which at least one functional section is fixed to the hard component section of the interface element or to a hard component section of the interface element receptacle or the functional section is formed by the respective hard component section. For example, it is possible for the hard component section to have or form at least one electrical contact or at least one coding rib and / or at least one guide rib and / or at least one stop rib. In such an embodiment, the hard component portion has substantially hard, static functions, whereas the positioning portion has the soft, dynamic functions, in particular the interception of vibrations and shocks and other forces, and guaranteeing mobility of the interface member relative to the interface member housing. The positioning section also preferably provides restoring forces, for example for applying a spring force to contacts fixed to the hard component section in the direction of a battery or a rechargeable battery.
Wie eingangs erwähnt, ist eine Ausführungsform des Schnitt- Stellenelementes als elektrisches Schnittstellenelement bevorzugt, bei dem ein als elektrischer Kontakt ausgebildeter Funktionsabschnitt vorgesehen ist, wobei der elektrische Kontakt, also der Funktionsabschnitt zum Herstellen einer elektrisch leitenden Verbindung zwischen einer Batterie und/oder einem Akkumulator und einer Elektrik, insbesondere einem Antriebsmotor und/oder einer Elektronik, des Elektrogerätes dient. Besonders bevorzugt ist eine Ausführungs- form, bei der der mindestens eine elektrische Kontakt von dem Hartkomponentenabschnitt des Schnittstellenelementes umspritzt ist. Ganz besonders bevorzugt ist eine Ausführungsform, bei der der Hartkomponentenabschnitt wiederum, zumindest abschnittsweise, insbesondere randseitig, von dem aus einem elastischen Material gebildeten Positionierabschnitt umspritzt ist.As mentioned above, an embodiment of the interface element is preferred as an electrical interface element, in which a designed as an electrical contact functional portion is provided, wherein the electrical contact, so the functional portion for producing a electrically conductive connection between a battery and / or an accumulator and an electrical system, in particular a drive motor and / or electronics, of the electrical appliance is used. Particularly preferred is an embodiment in which the at least one electrical contact is encapsulated by the hard component section of the interface element. Very particular preference is given to an embodiment in which the hard component section is in turn, at least in sections, in particular peripherally encapsulated by the positioning section formed from an elastic material.

On separate fastening means can be dispensed with due to the formation of the positioning advantageously. From Fig. 2, the formed as electrical contacts functional elements 7, 8 are shown in a view from below. It can also be seen that the hard component section 11 of the interface element receptacle 2 protrudes into the positioning section 9 in the radial direction - in other words, the hard component section 11 of the interface element receptacle 2 is encompassed in sections by the positioning section 9 of the interface element 1.
In Fig. 3 ist in einer schematischen, teilgeschnittenen Ansicht eine alternative Anordnung, umfassend ein Schnitt- Stellenelement 1 und eine Schnittstellenelementaufnähme 2 gezeigt. Das Schnittstellenelement 1 umfasst einen Hartkomponentenabschnitt 6, an dem als elektrische Kontakte ausgebildete Funktionsabschnitte 4, 5 festgelegt sind. Der Hart- komponentenabschnitt 6 ist randseitig umspritzt von einem einen Positionierabschnitt 9 bildenden elastischen Material. Der umlaufende Positionierabschnitt 9 wiederum ist in einer umlaufenden Aufnahmetasche 12 der Schnittelementauf- nähme 2 aufgenommen, wobei die Aufnahmetasche 12 wiederum von zwei parallel zueinander verlaufenden nach innen weisenden Stegen 13, 14 eines Hartkomponentenabschnittes 11 der Schnittstellenelementaufnähme 2 gebildet ist.In Fig. 3 is shown in a schematic, partially sectioned view of an alternative arrangement comprising a Schnittstelleelement 1 and a Schnittstellenelementaufnähme 2.
