Description

Die Erfindung betrifft ein Elektrogerät gemäß Anspruch 1.The invention relates to an electrical appliance according to claim 1.

Schnittstellenelemente, unter denen auch Schnittstellenbaugruppen 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 Schnittstellenelementaufnahme aufeinander bzw. ineinander gebracht werden. Häufig handelt es sich bei einem Schnittstellenelement um einen Batteriefachdeckel zum Verschließen eines Batteriefachs (Schnittstellenelementaufnahme) eines Elektrogerätes oder um eine (elektrische) Schnittstelle zwischen einem Batteriefach und einem elektrischen Antrieb oder einer Elektronik. Derartige Schnittstellenelemente weisen üblicherweise elektrische Kontakte auf, die an dem aus Hartkunststoff ausgebildeten Schnittstellenelement, meist durch Umspritzen, festgelegt sind. Neben oder anstelle einer elektrischen Kontaktierung können bekannte Schnittstellenelemente die unterschiedlichsten Funktionen erfüllen und hierzu beispielsweise Kodierrippen, Führungsrippen, Anschlagsrippen, etc. aufweisen.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 holder, are brought into or onto one another. Frequently, an interface element is a battery compartment cover for closing a battery compartment (interface element receptacle) of an electrical appliance or an (electrical) interface between a battery compartment and an electric drive or electronics. Such interface elements usually have electrical contacts, which are fixed to the formed of hard plastic interface element, usually by encapsulation. In addition to or instead of an electrical contacting known interface elements can perform a variety of functions and this example coding ribs, guide ribs, stop ribs, etc. have.

In der Praxis erfordern Schnittstellenpartner (Schnittstellenelement und Schnittstellenelementaufnahme) eine genaue Toleranzeinhaltung zueinander, um die Schnittstellenpartner relativ zueinander exakt positionieren zu können.In practice, interface partners (interface element and interface element mount) require accurate tolerance compliance with each other to accurately position the interface partners relative to 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 werden. Bei der schwimmenden Positionierung soll dem Schnittstellenelement hingegen die Möglichkeit gegeben werden, sich relativ zur Schnittstellenelementaufnahme zu bewegen, beispielsweise um Toleranzabweichungen auszugleichen oder Vibrationsverschiebungen zuzulassen. Bei der bekannten schwimmenden Positionierung besteht die Option, das Schnittstellenelement durch mechanische, aus starrem Material ausgebildete, Federelemente federnd zu gestalten, also eine schwimmende Lagerung mit Nennposition und Rückstellkräften zu realisieren. Alternativ ist eine nicht federnde, also frei schwimmende Positionierung der Schnittstellenpartner zueinander möglich.In the case of known interface partners, the positioning takes place either as far as possible without play or with a defined clearance, ie floating. In the play-free positioning as accurate as possible to be achieved. In the floating positioning, however, the interface element should be given the opportunity to move relative to the interface element recording, for example, to compensate for tolerance deviations or allow vibration shifts. At the known floating Positioning is the option to design the interface element by mechanical, formed of rigid material, spring elements 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 eine 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.A disadvantage of floating relative positionable interface partners is that they usually have a lack of contamination resistance, whereby the Relativverstellmöglichkeit between the interface partners is lost over time, with the result that the interface partners can no longer fulfill their function adequately. 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.

Aus der DE 10 2004 032 790 A1 ist ein Schnittstellenelement nach dem Oberbegriff des Anspruchs 1 bekannt. Das Schnittstellenelement umfasst einen aus Kunststoff bestehenden Kontaktträger, der Gegenkontakte trägt, die mit Kontakten an einer Batterie einer Elektrohandwerkzeugmaschine zusammenwirken. Der Kontaktträger ist innerhalb des Gehäuses der Elektrohandwerkzeugmaschine horizontal sowie vertikal um ein gewisses Maß beweglich angeordnet. Hierzu können beispielsweise an den Außenseiten des Kontaktträgers angespritzte, elastische Rippen oder Noppen vorgesehen sein. Alternativ dazu können derartige elastische Rippen oder Noppen jedoch auch in der Gehäuseaufnahme der Elektrohandwerkzeugmaschine vorgesehen sein, so dass an dem Kontaktträger keine derartigen elastischen Elemente angeordnet werden müssen. Derartige angespritzte Rippen oder Noppen, insbesondere wenn diese eine relativ geringe Größe aufweisen, haben den Nachteil, dass diese bei einer dauerhaften Belastung leicht beschädigt werden können.From the DE 10 2004 032 790 A1 an interface element according to the preamble of claim 1 is known. The interface element comprises a contact carrier made of plastic, which carries mating contacts, which interact with contacts on a battery of a power hand tool. The contact carrier is arranged to be movable horizontally and vertically to a certain extent within the housing of the electric power tool. For this purpose, for example, be provided on the outer sides of the contact carrier molded, elastic ribs or nubs. Alternatively, however, such elastic ribs or nubs may also be provided in the housing receptacle of the electric hand tool, so that no such elastic elements must be arranged on the contact carrier. Such molded ribs or nubs, especially if they have a relatively small size, have the disadvantage that they can be easily damaged in a permanent load.

In WO 2008/086806 A1 ist ein Elektrowerkzeug mit einem Gehäuse beschrieben. Im Gehäuse befindet sich ein Elektromotor und eine an Aufnahmen im Gehäuse befestigte elektrische und/oder elektronische Baugruppe, beispielsweise ein elektrischer Schalter oder eine Elektronik. Zwischen den Aufnahmen im Gehäuse und der elektrischen und/oder elektronischen Baugruppe ist eine Vibrationskopplung angeordnet.In WO 2008/086806 A1 is a power tool with a housing described. The housing contains an electric motor and an electrical and / or electronic assembly, for example an electrical switch or an electronic unit, attached to receptacles in the housing. Between the shots in the case and the electrical and / or electronic assembly is arranged a vibration coupling.

Allgemein haben sämtliche bekannten Schnittstellenpartner den Nachteil, dass stoßartige Belastungen von Hartkomponentenabschnitten aufgenommen werden, und, insbesondere bei dauerhafter Belastung, zu Bruch oder anderen Beschädigungen führen.In general, all known interface partners have the disadvantage that impulsive loads of hard component sections are absorbed, and, in particular under permanent load, lead to breakage or other damage.

Offenbarung der ErfindungDisclosure of the invention

Ausgehend von dem dargestellten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Elektrogerät nach dem Oberbegriff des Anspruchs 1 derart weiterzubilden, dass dieses einerseits mechanisch besonders robust ausgebildet ist um Beschädigungen zu vermeiden, und andererseits eine exakte relative Positionierung für mit dem Schnittstellenelement zusammenwirkende Teile zu ermöglichen. Diese Aufgabe wird erfindungsgemäß bei einem Elektrogerät mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Based on the illustrated prior art, the invention has the object, an electrical appliance according to the preamble of claim 1 such that on the one hand mechanically very robust to avoid damage, and on the other hand an exact relative positioning for interacting with the interface element parts to enable. This object is achieved in an electrical appliance with the features of claim 1. Advantageous developments of the invention are specified in the subclaims.

Der Erfindung liegt der Gedanke zugrunde, einen Positionierabschnitt aus einem elastischen Material vorzusehen,
(weiter auf Beschreibungsseite 4)
der ein Relativverschieben des Hartkomponentenabschnittes des Schnittstellenelementes relativ zur Schnittstellenelementaufnahme ermöglicht. Dabei liegt es im Rahmen der Erfindung, den Positionierabschnitt am Schnittstellenelement und/oder an der Schnittstellenelementaufnahme 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 Schnittstellenelementaufnahme 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 Schnittstellenelementaufnahme 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 ausgebildetes Schnittstellenelement bzw. eine nach dem Konzept der Erfindung ausgebildete Schnittstellenelementaufnahme kombiniert ausschließlich die Vorteile einer spielfreien und einer schwimmenden Positionierung und vermeidet deren Nachteile. So ist zum einen eine exakte Relativpositionierung 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 Schnittstellenelementaufnahme 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,
(continue on description page 4)
which allows a relative displacement of the hard component portion of the interface element relative to the interface element receptacle. It is within the scope of the invention to realize the positioning section on the interface element and / or on the interface element holder. 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 a positioning section formed of an elastic material between the hard component section of the interface element and a hard component section of the interface element holder, which permits a relative movement between the two hard component sections of the interface partners by its own elastic deformation. By forming the positioning section 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. Thus, on the one hand, an exact relative positioning of the interface partners to each other possible and at the same time the pollution resistance 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 portion of the interface element and the at least one hard component portion of the interface element receptacle is realized only by an (inner) material deformation of the positioning 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 Relativverschiebungsweges 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. It will be achieved low return forces near the neutral position and relatively high restoring forces at the end of Relativverschiebungsweges.

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 Schnittstellenelementaufnahme verbunden ist. Wesentlich ist, dass im aneinander festgelegten Zustand von Schnittstellenelement und Schnittstellenelementaufnahme und/oder beim Montieren der Schnittstellenpartner eine Relativbewegung des Hartkomponentenabschnittes des Schnittstellenelementes relativ zu einem Hartkomponentenabschnitt der Schnittstellenelementaufnahme 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 that the interface element is permanently fixed or detachably connected to the interface element receptacle. It is essential that a relative movement of the hard component section of the interface element relative to a hard component section of the interface element receptacle is made possible in the mutually fixed state of interface element and interface element receptacle and / or when mounting the interface partner.

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 20°C, weicher ist als das Kunststoffmaterial 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 portion at room temperature, ie at about 20 ° C, softer than the plastic material of the hard component portion. 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 Schnittstellenelementaufnahme hat. Hierzu ist es möglich, 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 interface element receptacle. 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-fitting 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 extrusion.

Von besonderem Vorteil ist eine Ausführungsform des Schnittstellenelementes bzw. der Schnittstellenelementaufnahme, bei der an dem Hartkomponentenabschnitt des Schnittstellenelementes oder an einem Hartkomponentenabschnitt der Schnittstellenelementaufnahme 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 mindestens 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 weichen, dynamischen Funktionen zukommen, insbesondere das Abfangen von Vibrationen und Stößen sowie sonstiger Kräfte und das Garantieren einer Beweglichkeit des Schnittstellenelementes relativ zur Schnittstellenelementaufnahme. 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 the interface element receptacle, wherein 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 the guarantee of mobility of the interface element relative to the interface element receiver. 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 Schnittstellenelementes 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 Ausführungsform, 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 portion 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.

Neben dem zuvor beschriebenen Schnittstellenelement und der zuvor beschriebenen Schnittstellenelementaufnahme führt die Erfindung auf ein Elektrogerät mit einem zuvor beschriebenen Schnittstellenelement und/oder einer zuvor beschriebenen Schnittstellenelementaufnahme. Dabei ist es möglich, dass sowohl das Schnittstellenelement als auch die Schnittstellenelementaufnahme jeweils einen Positionierabschnitt aus einem elastischen Material aufweisen, wobei die beiden Positionierabschnitte im montierten Zustand unmittelbar aneinander anliegen. Besonders bevorzugt ist es jedoch, entweder nur dem Schnittstellenelement oder nur der Schnittstellenelementaufnahme einen Positionierabschnitt aus einem elastischen Material unmittelbar zuzuordnen, wobei der Positionierabschnitt im montierten Zustand unmittelbaren Kontakt zu einem Hartkomponentenabschnitt des jeweils anderen Bauelementes der Schnittstellenelementaufnahme oder des Schnittstellenelementes hat.In addition to the interface element described above and the interface element holder described above, the invention leads to an electrical device having an interface element described above and / or an interface element receptacle described above. In this case, it is possible that both the interface element and the interface element receptacle each have a positioning section made of an elastic material, the two positioning sections abutting one another directly in the mounted state. However, it is particularly preferable to assign a positioning section of an elastic material either directly to the interface element or only to the interface element receptacle, wherein the positioning section in the mounted state has direct contact with a hard component section of the respective other component of the interface element receptacle or of the interface element.

Darüber hinaus führt die Erfindung auf eine Verwendung eines zuvor beschriebenen Schnittstellenelementes und/oder einer zuvor beschriebenen Schnittstellenelementaufnahme in oder an einem Elektrogerät, insbesondere einem Elektrowerkzeug oder einem Haushaltsgerät, besonders bevorzugt in oder an einem Elektrohandwerkzeug, insbesondere zur Ausbildung einer Schnittstelle zwischen zwei Funktionsabschnitten des Elektrogerätes.In addition, the invention leads to a use of a previously described interface element and / or a previously described interface element receptacle in or on an electrical appliance, in particular a power tool or a domestic appliance, particularly preferably in or on an electric hand tool, in particular for forming an interface between two functional sections of the electrical appliance.

Ausführungsformen der Erfindung In den Figuren sind gleiche Bauteile und Bauteile mit der gleichen Funktion mit den gleichen Bezugszeichen gekennzeichnet.Embodiments of the invention In the figures, the same components and components with the same function with the same reference numerals.

In Fig. 1 ist eine Anordnung bestehend aus einem als elektrisches Schnittstellenelement ausgebildeten Schnittstellenelement 1 und einer das Schnittstellenelement 1 haltenden Schnittstellenelementaufnahme 2 gezeigt. Die Schnittstellenelementaufnahme 2 ist in dem gezeigten Ausführungsbeispiel Bestandteil eines Gehäuses 3 eines nicht weiter dargestellten Elektrogerätes, umfassend einen ebenfalls nicht gezeigten elektrischen Antriebsmotor.In Fig. 1 is an arrangement consisting of an interface element designed as an electrical interface element 1 and the interface element 1 holding interface element receptacle 2 shown. The interface element receptacle 2 is in the embodiment shown part of a housing 3 of an electric appliance, not shown, comprising an electric drive motor, also not shown.

Das nach der einmaligen Montage dauerhaft in der Schnittstellenelementaufnahme 2 gehaltene Schnittstellenelement 1 stellt mit Hilfe von als elektrische Kontakte ausgebildeten Funktionsabschnitten 4, 5 den elektrischen Kontakt zwischen nicht gezeigten Akkumulatoren und dem ebenfalls nicht gezeigten elektrischen Antriebsmotor des Elektrogerätes her.The interface element 1 permanently held in the interface element receptacle 2 after the one-time installation, with the aid of functional sections 4, 5 designed as electrical contacts, establishes electrical contact between accumulators (not shown) and the electric drive motor of the electrical device, also not shown.

Zu erkennen ist ein Hartkomponentenabschnitt 6 des Schnittstellenelementes 1, mit dem die als metallische, elektrische Kontakte ausgebildeten Funktionselemente 4, 5 umspritzt sind. Am Hartkomponentenabschnitt 6 sind weitere, als Kodierrippen ausgebildete Funktionsabschnitte 7, 8 ausgeformt.Evident is a hard component section 6 of the interface element 1, with which the metallic, electrical contacts formed as functional elements 4, 5 are encapsulated. At the hard component portion 6 further, designed as Kodierrippen functional sections 7, 8 are formed.

Der Hartkomponentenabschnitt 6 ist randseitig umspritzt von einem Positionierabschnitt 9, bestehend aus Elastomermaterial, hier TPE. Das Verbundbauteil (hier Mehrkomponentenspritzgussteil) umfassend den Hartkomponentenabschnitt 6 und den Positionierabschnitt 9 ist mit Hilfe des Positionierabschnitts 9 in einer Ausnehmung 10 eines Hartkomponentenabschnitts 11 der Schnittstellenelementaufnahme 2 klemmend gehalten. Durch die elastische Ausbildung des Positionierabschnittes 9 ist der Hartkomponentenabschnitt 6 mit seinen Funktionsabschnitten 4, 5, 7, 8 in gewissen Grenzen relativ zu dem Hartkomponentenabschnitt 11 der Schnittstellenelementaufnahme 2 in sämtliche Raumrichtungen beweglich.The hard component portion 6 is peripherally encapsulated by a positioning section 9, consisting of elastomeric material, here TPE. The composite component (here multicomponent injection-molded part) comprising the hard component section 6 and the positioning section 9 is in a recess 10 of a hard component section with the aid of the positioning section 9 11 of the interface element holder 2 clamped. Due to the elastic configuration of the positioning section 9, the hard component section 6 with its functional sections 4, 5, 7, 8 is movable within certain limits relative to the hard component section 11 of the interface element receptacle 2 in all spatial directions.

In Fig. 2 ist eine weitere perspektivische Ansicht der Anordnung aus Schnittstellenelement 1 und Schnittstellenelementaufnahme 2 gemäß Fig. 1 gezeigt, wobei das Schnittstellenelement 1 in einer Ansicht von oben zu sehen ist. Zu erkennen ist der zentrische Hartkomponentenabschnitt 6 der randseitig von dem Positionierabschnitt 9 umspritzt ist, welcher wiederum das Schnittstellenelement 1 in der Schnittstellenelementaufnahme 2 festlegt. Auf separate Befestigungsmittel kann aufgrund der Ausbildung des Positionierabschnitts mit Vorteil verzichtet werden. Aus Fig. 2 sind die als elektrische Kontakte ausgebildeten Funktionselemente 7, 8 in einer Ansicht von unten gezeigt. Zu erkennen ist ferner, dass der Hartkomponentenabschnitt 11 der Schnittstellenelementaufnahme 2 in radialer Richtung ein Stück weit in den Positionierabschnitt 9 hineinragt - anders ausgedrückt wird der Hartkomponentenabschnitt 11 der Schnittstellenelementaufnahme 2 abschnittsweise von dem Positionierabschnitt 9 des Schnittstellenelementes 1 umgriffen.In Fig. 2 is a further perspective view of the arrangement of interface element 1 and interface element receptacle 2 according to Fig. 1 shown, wherein the interface element 1 can be seen in a view from above. Evident is the centric hard component section 6 which is encapsulated on the edge side by the positioning section 9, which in turn defines the interface element 1 in the interface element holder 2. On separate fastening means can be dispensed with due to the formation of the positioning advantageously. Out Fig. 2 are formed as electrical contacts functional elements 7, 8 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 Schnittstellenelement 1 und eine Schnittstellenelementaufnahme 2 gezeigt. Das Schnittstellenelement 1 umfasst einen Hartkomponentenabschnitt 6, an dem als elektrische Kontakte ausgebildete Funktionsabschnitte 4, 5 festgelegt sind. Der Hartkomponentenabschnitt 6 ist randseitig umspritzt von einem einen Positionierabschnitt 9 bildenden elastischen Material. Der umlaufende Positionierabschnitt 9 wiederum ist in einer umlaufenden Aufnahmetasche 12 der Schnittelementaufnahme 2 aufgenommen, wobei die Aufnahmetasche 12 wiederum von zwei parallel zueinander verlaufenden nach innen weisenden Stegen 13, 14 eines Hartkomponentenabschnittes 11 der Schnittstellenelementaufnahme 2 gebildet ist.In Fig. 3 is an alternative arrangement, comprising an interface element 1 and an interface element receptacle 2 shown in a schematic, partially sectional view. The interface element 1 comprises a hard component section 6, on which functional sections 4, 5 designed as electrical contacts are fixed. The hard component section 6 is peripherally encapsulated by an elastic material forming a positioning portion 9. The peripheral positioning section 9 in turn is received in a circumferential receiving pocket 12 of the sectional element holder 2, the receiving pocket 12 in turn being formed by two mutually parallel inwardly directed webs 13, 14 of a hard component section 11 of the interface element holder 2.

In Fig. 4 ist eine alternative Anordnung, umfassend ein Schnittstellenelement 1 sowie eine Schnittstellenelementaufnahme 2 gezeigt. Im Gegensatz zu dem Ausführungsbeispiel gemäß Fig. 3 ist der Positionierabschnitt 9 nicht integraler Bestandteil des Schnittstellenelementes 1, sondern integraler Bestandteil der Schnittstellenelementaufnahme 2. Hierzu ist der Positionierabschnitt 9 mit einem Hartkomponentenabschnitt 11 der Schnittstellenelementaufnahme 2 als Mehrkomponentenspritzgussteil ausgebildet. Alternativ kann der Positionierabschnitt 9 auch als von dem Hartkomponentenabschnitt 11 separates Bauteil ausgebildet sein und beispielsweise durch Klemmen an dem Hartkomponentenabschnitt 11 gehalten werden. Weiter alternativ ist ein Festlegen des Positionierabschnittes 9 durch Kleben am Hartkomponentenabschnitt 11 realisierbar.In Fig. 4 is an alternative arrangement, comprising an interface element 1 and an interface element receptacle 2 shown. In contrast to the embodiment according to Fig. 3 is the positioning section 9 is not an integral part of the interface element 1, but an integral part of the interface element receptacle 2. For this purpose, the positioning section 9 is formed with a hard component portion 11 of the interface element receptacle 2 as a multi-component injection molded part. Alternatively, the positioning section 9 may also be formed as a separate component from the hard component section 11 and be held, for example, by clamping on the hard component section 11. Further alternatively, a fixing of the positioning portion 9 by gluing the hard component portion 11 can be realized.

Wie aus Fig. 4 hervorgeht, ist der Positionierabschnitt 9 im Querschnitt U-förmig ausgebildet und bildet eine Aufnahmetasche für das Schnittstellenelement 1. Der Positionierabschnitt 9 ist dabei in einer Aufnahmetasche 12 der Schnittstellenelementaufnahme 2 gehalten, wobei die Aufnahmetasche 12 in Analogie zu Fig. 3 von zwei parallelen Stegen 13, 14 gebildet ist.How out Fig. 4 shows, the positioning portion 9 is formed in cross-section U-shaped and forms a receiving pocket for the interface element 1. The positioning portion 9 is held in a receiving pocket 12 of the interface element holder 2, wherein the receiving pocket 12 in analogy to Fig. 3 is formed by two parallel webs 13, 14.

Von dem Positionierabschnitt 9 der Schnittstellenelementaufnahme 2 ist ein Hartkomponentenabschnitt 6 des Schnittstellenelementes 1 gehalten, wobei von dem Hartkomponentenabschnitt 6 als elektrische Kontakte ausgebildete Funktionsabschnitte 4, 5 zum Herstellen eines elektrischen Kontaktes zu einem Akkumulator umspritzt sind.Of the positioning section 9 of the interface element holder 2, a hard component section 6 of the interface element 1 is held, wherein functional sections 4, 5 formed by the hard component section 6 as electrical contacts are encapsulated to produce an electrical contact to an accumulator.
