Description

Die Erfindung betrifft ein elektrisches Gerät gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an electrical device according to the preamble of claim 1.

Ein lektrisches Gerät mit einem Auswurfmechanismus ist aus der DE 20 2007 004 414 U1 bekannt. Aus der EP 2 961 003 A1 ist ein elektrisches Gerät mit einem Auswurfmechanismus gemäß dem Oberbegriff des Anspruches 1 bekannt. Aus der US 5,672,072 ist ein elektrisches Gerät gemäß dem Oberbegriff des Anspruches 1 bekannt. Aus der US 4,241,966 ist ein elektrisches Gerät mit einem Auswurfmechanismus bekannt.An electrical device with an ejection mechanism is from the DE 20 2007 004 414 U1 known. From the EP 2 961 003 A1 an electrical device with an ejection mechanism according to the preamble of claim 1 is known. From the U.S. 5,672,072 an electrical device according to the preamble of claim 1 is known. From the U.S. 4,241,966 an electrical device with an ejection mechanism is known.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, ein elektrisches Gerät mit einer solchen Auswurfeinrichtung anzugeben, die bei zuverlässiger Funktion einfach zu realisieren ist.In contrast, the invention is based on the object of specifying an electrical device with such an ejection device, which can be easily implemented while functioning reliably.

Diese Aufgabe wird mit einem elektrischen Gerät gemäß Anspruch 1 gelöst. Dies umfasst, dass der Auswerferhebel ohne feste Verschwenkachse an dem elektrischen Gerät schwenkbar gelagert ist und zur Ausführung einer Verschwenkbewegung bei einem Auswurf-Vorgang eingerichtet ist, deren Verschwenkachse im Verlaufe eines Auswurf-Vorgangs ortsveränderlich ist. Die Erfindung hat den Vorteil, dass die Auswurfeinrichtung und insbesondere der Auswerferhebel besonders einfach und mit wenigen Bauteilen realisiert werden kann. Insbesondere ist keine feste Lagerung des Auswerferhebels erforderlich, wie im Stand der Technik. Dementsprechend müssen keine Lagerungselemente wie Lagerachsen oder Lagerzapfen vorgesehen werden. Beim Verschwenken des Auswerferhebels kann dieser eine Abrollbewegung ausführen. Das elektrische und/oder elektronische Bauelement kann damit auf einfache Weise aus dem Aufnahmeschacht herausgehebelt werden.This object is achieved with an electrical device according to claim 1. This includes that the eject lever is pivotably mounted on the electrical device without a fixed pivot axis and is set up to execute a pivoting movement during an ejection process, the pivot axis of which is movable in the course of an ejection process. The invention has the advantage that the ejection device and in particular the eject lever can be implemented in a particularly simple manner and with few components. In particular, no fixed mounting of the ejector lever is required, as in the prior art. Accordingly, no bearing elements such as bearing axles or bearing journals have to be provided. When the ejector lever is pivoted, it can execute a rolling movement. The electrical and / or electronic component can thus be levered out of the receiving shaft in a simple manner.

Durch die erfindungsgemäße Auswurfeinrichtung kann eine zu Beginn der Verschwenkbewegung aus dem Hebelarmverhältnis resultierende geringere Betätigungskraft realisiert werden, wodurch die Dimensionen der Bauteile, insbesondere des Auswerferhebels, verkleinert werden können und der Betätigungsvorgang besonders ergonomisch gestaltet wird.With the ejection device according to the invention, a lower actuating force resulting from the lever arm ratio at the beginning of the pivoting movement can be implemented, whereby the dimensions of the components, in particular the ejector lever, can be reduced and the actuation process is made particularly ergonomic.

Der Auswerferhebel kann bei einem Auswurf-Vorgang manuell durch eine Druckkraft oder eine Zugkraft beaufschlagt werden. Vorteilhaft ist insbesondere eine Betätigungskraft mit einer Wirkrichtung, die entgegen der Wirkrichtung der auf das Bauelement ausgeübten Druckkraft ausgerichtet ist. Dies erlaubt eine angenehme und effiziente manuelle Betätigung des Auswerferhebels. Gemäß einer vorteilhaften Weiterbildung der Erfindung ist daher vorgesehen, dass durch den Auswerferhebel eine auf den Auswerferhebel infolge manueller Betätigung des Auswerferhebels einwirkende Betätigungskraft in die auf das Bauelement ausgeübte Druckkraft umlenkbar ist, wobei die Wirkrichtung der Betätigungskraft entgegen der Wirkrichtung der auf das Bauelement ausgeübten Druckkraft ausgerichtet sein kann. Auf diese Weise kann das Bauelement von seiner Unterseite her, d.h. der zum Boden des Aufnahmeschachts gewandten Seite, aus dem Aufnahmeschacht herausgedrückt werden.During an ejection process, the ejector lever can be acted upon manually by a compressive force or a tensile force. In particular, an actuating force with an effective direction which is oriented counter to the effective direction of the compressive force exerted on the component is advantageous. This allows a comfortable and efficient manual operation of the ejector lever. According to an advantageous development of the invention it is therefore provided that an actuating force acting on the ejector lever as a result of manual actuation of the ejector lever can be diverted into the compressive force exerted on the component by the ejector lever, the effective direction of the actuating force being directed against the effective direction of the compressive force exerted on the component can be. In this way, the component can be pushed out of the receiving shaft from its underside, i.e. the side facing the bottom of the receiving shaft.

Der Auswerferhebel kann insbesondere als fester Bestandteil des elektrischen Geräts ausgebildet sein, d.h. der Auswerferhebel wird herstellerseitig gleich als Teil des elektrischen Geräts bereitgestellt und ist dementsprechend nicht dazu eingerichtet, vom elektrischen Gerät entfernt zu werden. Somit ist der Auswerferhebel dann nicht Bestandteil des auszuwerfenden elektrischen und/oder elektronischen Bauelementes, sodass der Auswerferhebel kein Fixierungselement zum Fixieren an dem auszuwerfenden elektrischen und/oder elektronischen Bauelement aufweist. Der Auswerferhebel kann z.B. über eine Zapfen-Langloch-Befestigung mit dem elektrischen Gerät, insbesondere dem Gehäuse des elektrischen Geräts, verbunden sein. Dementsprechend weist der Auswerferhebel auch gegenüber dem auszuwerfenden elektrischen und/oder elektronischen Bauelement keine feste Verschwenkachse auf. Hierdurch ist der Auswerferhebel auch gegenüber dem elektrischen und/oder elektronischen Bauelement im Verlauf eines Auswurf-Vorgangs ortsveränderlich.The ejector lever can in particular be designed as a fixed component of the electrical device, ie the ejector lever is provided by the manufacturer as part of the electrical device and is accordingly not set up to be removed from the electrical device. The ejector lever is then not part of the electrical and / or electronic component to be ejected, so that the ejector lever does not have a fixing element for fixing to the electrical and / or electronic component to be ejected. The ejector lever can be connected to the electrical device, in particular the housing of the electrical device, for example via a pin and slot fastening. Accordingly, the ejector lever also does not have a fixed pivot axis with respect to the electrical and / or electronic component to be ejected. As a result, the eject lever can also be moved in relation to the electrical and / or electronic component in the course of an ejection process.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Auswerferhebel ein manuelles Betätigungselement aufweist, an dem der Auswerferhebel unmittelbar manuell zum Herausdrücken des Bauelementes aus dem Aufnahmeschacht zu betätigen ist. Das manuelle Betätigungselement kann z.B. als Griffmulde ausgebildet sein und/oder eine strukturierte Oberfläche aufweisen, um ein Abrutschen zu verhindern, z.B. eine geriffelte und/oder genoppte Oberfläche. Das manuelle Betätigungselement kann zusätzlich einen Aufnahmeschlitz für ein Betätigungswerkzeug aufweisen, z.B. für einen Schraubendreher.According to an advantageous development of the invention it is provided that the eject lever has a manual actuating element on which the eject lever can be actuated directly manually to push the component out of the receiving shaft. The manual actuating element can, for example, be designed as a recessed grip and / or have a structured surface in order to prevent slipping, e.g. a corrugated and / or knobbed surface. The manual operating element can additionally have a receiving slot for an operating tool, e.g. for a screwdriver.

Gemäß der Erfindung ist vorgesehen, dass das elektrische Gerät eine bezüglich des Aufnahmeschachts ortsfeste Abrollkontur zur Auflagerung des Auswerferhebels aufweist, auf der der Auswerferhebel bei einem Auswurf-Vorgang abrollbar ist, so dass die Verschwenkachse ortsveränderlich ist. Hierdurch wird der abrollende Bewegungsvorgang des Auswerferhebels unterstützt. Die Abrollbewegung des Auswerferhebels auf der Abrollkontur kann dabei im Wesentlichen ohne Gleitbewegung, d.h. ohne Schlupf zwischen der Abrollkontur und dem Auswerferhebel, erfolgen. Auf diese Weise wird ein Verschleiß an diesen Bauteilen vermieden. Gelegentlich auftretende geringe Relativbewegungen zwischen den Bauteilen sind dagegen unkritisch.According to the invention, it is provided that the electrical device has a rolling contour that is stationary with respect to the receiving shaft for supporting the ejector lever, on which the ejector lever can be rolled during an ejection process, so that the pivot axis is movable. This supports the rolling movement of the ejector lever. The rolling movement of the ejector lever on the rolling contour can essentially take place without sliding movement, i.e. without slippage between the rolling contour and the ejector lever. In this way, wear and tear on these components is avoided. Occasional slight relative movements between the components are, however, not critical.

Die Abrollkontur kann eine ununterbrochene (durchgängige) Kontur oder eine nicht durchgängige Kontur sein. Im letztgenannten Fall kann die Abrollkontur Unterbrechungen aufweisen oder aus diskreten Punkten und/oder Abschnitten bestehen, auf denen dann die Lagerungskontur des Auswerferhebels abrollt. Eine derartige Ausbildung der Abrollkontur kann z.B. sinnvoll sein, wenn Platz für die Gegenkontakte innerhalb des elektrischen Geräts benötigt wird.The rolling contour can be an uninterrupted (continuous) contour or a discontinuous contour. In the latter case, the rolling contour can have interruptions or consist of discrete points and / or sections on which the bearing contour of the ejector lever then rolls. Such a design of the rolling contour can be useful, for example, if space is required for the mating contacts within the electrical device.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die ortsveränderliche Verschwenkachse durch den Auflagerpunkt der Lagerungskontur des Auswerferhebels auf der Abrollkontur gebildet wird. Dieser Auflagerpunkt ist damit ein Momentandrehpunkt des Auswerferhebels.According to an advantageous development of the invention it is provided that the movable pivot axis is formed by the point of support of the bearing contour of the ejector lever on the rolling contour. This support point is thus an instantaneous pivot point of the ejector lever.

Gemäß der Erfindung ist vorgesehen, dass der Auswerferhebel eine linear verlaufende Lagerungskontur aufweist, mit der der Auswerferhebel auf der Abrollkontur aufgelagert ist. Gemäß der Erfindung ist vorgesehen, dass der Auswerferhebel eine relativ zur Abrollkontur konvex verlaufende Lagerungskontur aufweist, mit der der Auswerferhebel auf der Abrollkontur aufgelagert ist. Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Auswerferhebel eine relativ zur Abrollkontur konkav verlaufende Lagerungskontur aufweist, mit der der Auswerferhebel auf der Abrollkontur aufgelagert ist, wobei die Lagerungskontur einen größeren Krümmungsradius aufweist als die Abrollkontur.According to the invention it is provided that the ejector lever has a linearly running bearing contour with which the ejector lever is supported on the rolling contour. According to the invention it is provided that the ejector lever has convex storage contour relative to the rolling contour with which the ejector lever is supported on the rolling contour. According to an advantageous development of the invention, it is provided that the ejector lever has a bearing contour that is concave relative to the rolling contour, with which the ejector lever is supported on the rolling contour, the bearing contour having a larger radius of curvature than the rolling contour.

Wie man erkennt, sind diverse Möglichkeiten für die Ausgestaltung der Formgebung der Konturen zwischen dem Auswerferhebel und der Abrollkontur möglich. Die zuvor genannten Möglichkeiten sind erfindungsgemäß miteinander kombiniert, indem die Abrollkontur eine Kombination aus linear verlaufenden und konvex verlaufenden Abschnitten der Abrollkontur aufweist. Vergleichbare Gestaltungen sind bezüglich der Lagerungskontur des Auswerferhebels möglich. Dies ermöglicht es, die Konturen derart aufeinander abzustimmen, dass die gewünschte Verschwenkung des Auswerferhebels einschließlich des Abrollvorgangs realisiert wird.As can be seen, there are various possibilities for designing the shape of the contours between the ejector lever and the rolling contour. According to the invention, the aforementioned possibilities are combined with one another in that the rolling contour has a combination of linear and convex sections of the rolling contour. Similar designs are possible with regard to the bearing contour of the ejector lever. This makes it possible to coordinate the contours with one another in such a way that the desired pivoting of the ejector lever, including the rolling process, is realized.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das elektrische Gerät ein Isolierstoffgehäuse aufweist und die Abrollkontur an dem Isolierstoffgehäuse ausgebildet ist, z.B. durch eine Gehäusekante oder einen Gehäusevorsprung. Dies erlaubt eine sehr kostengünstige Realisierung der Abrollkontur durch Integration in den Fertigungsprozess des Isolierstoffgehäuses.According to an advantageous development of the invention it is provided that the electrical device has an insulating material housing and the rolling contour is formed on the insulating material housing, e.g. by a housing edge or a housing projection. This allows the rolling contour to be implemented very inexpensively by integrating it into the manufacturing process of the insulating material housing.

Der Auswerferhebel kann als gerader Hebel oder als geknickter Hebel ausgebildet sein, z.B. als Winkelhebel.The ejector lever can be designed as a straight lever or as a bent lever, e.g. as an angle lever.

Der Auswerferhebel weist einen Kraftarm und einen Lastarm auf. Im Falle eines zweiseitigen Hebels befindet sich der Lastarm bezüglich der Verschwenkachse des Auswerferhebels auf der zum elektrischen und/oder elektronischen Bauelement gewandten Seite, der Kraftarm auf der dem manuellen Betätigungselement zugewandten Seite der Verschwenkachse. Die Verschwenkachse entspricht dabei auch dem Drehpunkt des Auswerferhebels.The eject lever has a force arm and a load arm. In the case of a two-sided lever, the load arm is located on the side of the pivot axis facing the electrical and / or electronic component with respect to the pivot axis of the ejector lever, and the force arm is located on the side of the pivot axis facing the manual actuating element. The pivot axis also corresponds to the pivot point of the ejector lever.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass sich durch die örtliche Veränderung der Verschwenkachse das Hebelverhältnis Kraftarm/Lastarm des Auswerferhebels bei einem Auswurf-Vorgang verändert, insbesondere dass sich das Hebelverhältnis vom Beginn zum Ende des Auswurf-Vorgangs verringert. Auf diese Weise kann zu Beginn des Auswurf-Vorgangs eine große Kraft bei geringer Wegänderung auf das auszuwerfende Bauelement übertragen werden. Zum Ende des Auswurf-Vorgangs, wenn weniger Betätigungskraft an dem auszuwerfenden Bauelement erforderlich ist, wird dagegen ein vergrößerter Betätigungsweg übertragen, was insgesamt dazu führt, dass der Auswurf-Vorgang des Bauelementes bei für den Anwender angenehmer Betätigungskraft schnell durchgeführt werden kann. Zu Beginn des Auswurf-Vorgangs sind an dem Bauelement größere Kräfte erforderlich, da dieses noch durch elektrische Steckkontakte an Gegensteckkontakten des elektrischen Geräts gehalten ist. Zum Ende des Auswurf-Vorgangs ist dieser mechanische Widerstand nicht mehr vorhanden, es ist lediglich noch das Bauelement anzuheben.According to an advantageous further development of the invention, the local change in the pivot axis changes the lever ratio of the force arm / load arm of the ejector lever during an ejection process, in particular that the lever ratio is reduced from the beginning to the end of the ejection process. In this way, at the beginning of the ejection process, a large force can be transmitted to the component to be ejected with a small change in path. At the end of the ejection process, when less actuation force is required on the component to be ejected, however, an increased actuation path is transmitted, which overall means that the ejection process of the component can be carried out quickly with an actuation force that is comfortable for the user. At the beginning of the ejection process, greater forces are required on the component because it is still held by electrical plug contacts on mating plug contacts of the electrical device. At the end of the ejection process, this mechanical resistance is no longer present, all that remains is to lift the component.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass sich das Hebelverhältnis Kraftarm/Lastarm bei einem Auswurf-Vorgang um wenigstens 10 %, insbesondere um wenigstens 20 %, verändert. Die Veränderung des Hebelverhältnisses kann auch noch größere Werte annehmen, z.B. wenigstens 40 %. Auch hierdurch kann die besonders ergonomische Betätigung der erfindungsgemäßen Auswurfeinrichtung weiter gefördert werden.According to an advantageous development of the invention, it is provided that the lever ratio of the force arm / load arm changes by at least 10%, in particular by at least 20%, during an ejection process. The change in the leverage ratio can also take on even larger values, e.g. at least 40%. The particularly ergonomic actuation of the ejection device according to the invention can also be further promoted in this way.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen unter Verwendung von Zeichnungen näher erläutert.The invention is explained in more detail below on the basis of exemplary embodiments using drawings.

Das elektrische Gerät 1 weist ein Isolierstoffgehäuse 11 auf. In dem Isolierstoffgehäuse 11 ist ein Aufnahmeschacht 10 zur lösbaren Aufnahme des Bauelementes 2 vorhanden. Das Bauelement 2 kann in den Aufnahmeschacht 10 eingesteckt werden und über seine Kontaktelemente 21 mit Gegenkontaktelementen des elektrischen Geräts 1, die nicht dargestellt sind, nach Art einer Steckverbindung verbunden werden. In manchen Fällen soll das Bauelement 2 ausgetauscht werden. Da das Bauelement 2 in verschiedenen Einbausituationen nicht ohne weiteres von Hand gegriffen werden kann, um es aus dem Aufnahmeschacht 10 herauszuziehen, weist das elektrische Gerät 1 eine Auswurfeinrichtung zum Durchführen eines Auswurf-Vorgangs des Bauelementes 2 aus dem Aufnahmeschacht 10 auf.The electrical device 1 has a housing 11 made of insulating material. In the insulating material housing 11 there is a receiving shaft 10 for the detachable receiving of the component 2. The component 2 can be plugged into the receiving shaft 10 and connected via its contact elements 21 to mating contact elements of the electrical device 1, which are not shown, in the manner of a plug-in connection. In some cases the component 2 should be exchanged. Since the component 2 cannot easily be gripped by hand in various installation situations in order to pull it out of the receiving slot 10, the electrical device 1 has an ejection device for carrying out an ejection process of the component 2 from the receiving slot 10.

Die Auswurfeinrichtung weist einen Auswerferhebel 3 auf, der mit seinem Hebelarm 30 unterhalb des Bauelementes 2 angeordnet ist und sich bis unter dessen Unterseite 20, die zum Boden des Aufnahmeschachts 10 hin gerichtet ist, erstreckt. Der Auswerferhebel 3 ist auf einer Abrollkontur 4 aufgelagert, d.h. er stützt sich nach unten hin auf dieser Abrollkontur 4 ab. Der Auswerferhebel 3 weist an einem Ende des Hebelarms 30 das manuelle Betätigungselement 31 auf, an dem der Auswerferhebel 3 unmittelbar manuell zu betätigen ist, um das Bauelement 2 aus dem Aufnahmeschacht 10 zu entfernen. Am anderen Ende weist der Hebelarm 30 das Druckelement 32 auf, mit dem eine Druckkraft von unten gegen das Bauelement 2, d.h. gegen dessen Unterseite 20, ausgeübt werden kann.The ejector device has an ejector lever 3, which is arranged with its lever arm 30 below the component 2 and extends to below its underside 20, which is directed towards the bottom of the receiving shaft 10. The ejector lever 3 is supported on a rolling contour 4, i.e. it is supported downwards on this rolling contour 4. At one end of the lever arm 30, the ejector lever 3 has the manual actuating element 31, on which the ejector lever 3 is to be actuated manually in order to remove the component 2 from the receiving shaft 10. At the other end, the lever arm 30 has the pressure element 32, with which a pressure force can be exerted from below against the component 2, i.e. against its underside 20.

Die Figur 1 zeigt die erläuterten Elemente in einem Zustand, in dem der Auswerferhebel 3 nicht betätigt ist und das Bauelement 2 vollständig in dem Aufnahmeschacht 10 eingesteckt ist. Die Figur 2 zeigt die Elemente bei dem Auswurf-Vorgang, die Figur 3 zeigt die Elemente am Ende des Auswurf-Vorgangs, wenn das Bauelement 2 von Hand aus dem Aufnahmeschacht 10 entnommen werden kann. Der Auswerferhebel 3 weist an seiner der Abrollkontur 4 zugewandten Seite eine Lagerungskontur 34 auf, wobei die Lagerungskontur 34 in einem Auflagerpunkt 5 auf der Abrollkontur 4 aufliegt bzw. sich auf der Abrollkontur 4 abstützt. Wie man erkennt, ist zunächst (Figur 1) der Auflagerpunkt 5 des Hebelarms 30 an der Abrollkontur 4 sehr weit rechts, d.h. nahe dem einen Ende der Abrollkontur 4 angeordnet. Der Hebelarm 30 teilt sich auf in einen Kraftarm, der sich von dem Auflagerpunkt 5 nach links in Richtung des Betätigungselements 31 und bis hin zum Betätigungselement 31 erstreckt, und einen Lastarm, der sich vom Auflagerpunkt 5 nach rechts in Richtung des Druckelements 32 und bis hin zum Druckelement 32 erstreckt. Wie die Figur 2 zeigt, wandert der Auflagerpunkt 5 mit zunehmender Verschwenkung des Auswerferhebels 3 nach links in Richtung des Betätigungselements 32. Das Bauelement 2 wird über das Druckelement 32 nach Art eines Stößels aus dem Aufnahmeschacht 10 durch eine von unten wirkende Druckkraft herausgedrückt. In der Figur 3 ist dieser Vorgang noch weiter durchgeführt, wobei man erkennt, dass der Auflagerpunkt 5 nun sehr weit nach links gewandert ist, etwa bis zum anderen Ende der Abrollkontur 4. Der Auflagerpunkt 5 kennzeichnet dabei die Verschwenkachse des Auswerferhebels 3.The Figure 1 shows the elements explained in a state in which the ejector lever 3 is not actuated and the component 2 is completely inserted into the receiving slot 10. The Figure 2 shows the elements during the ejection process; FIG. 3 shows the elements at the end of the ejection process when the component 2 can be removed from the receiving shaft 10 by hand. The ejector lever 3 has a bearing contour 34 on its side facing the rolling contour 4, the bearing contour 34 resting at a support point 5 on the rolling contour 4 or being supported on the rolling contour 4. As can be seen, the support point 5 of the lever arm 30 on the rolling contour 4 is initially (FIG. 1) arranged very far to the right, ie near one end of the rolling contour 4. The lever arm 30 is divided into a force arm, which extends from the support point 5 to the left in the direction of the actuating element 31 and up to the actuating element 31, and a load arm, which extends from the support point 5 to the right in the direction of the pressure element 32 and up to extends to the pressure element 32. As the Figure 2 shows, the support point 5 moves with increasing pivoting of the ejector lever 3 to the left in the direction of the actuating element 32. The component 2 is pushed out of the receiving shaft 10 via the pressure element 32 in the manner of a ram by a pressure force acting from below. In the Figure 3 If this process is carried out even further, it can be seen that the support point 5 has now moved very far to the left, approximately to the other end of the rolling contour 4. The support point 5 characterizes the pivot axis of the ejector lever 3.

Man erkennt ferner, dass sich im Laufe der Verschwenkbewegung des Auswerferhebels 3 das Verhältnis zwischen der Länge des Kraftarms zur Länge des Lastarms (Hebelverhältnis Kraftarm/Lastarm) in Folge der Verschiebung des Auflagerpunkts 5 deutlich verringert, z.B. wenigstens um den Faktor 1,5. Man erkennt ferner, dass der Auswerferhebel 3 eine reine Abrollbewegung auf der Abrollkontur 4 ausführt, d.h. im Wesentlichen keine Gleitbewegung gegenüber der Abrollkontur 4 auftritt.It can also be seen that in the course of the pivoting movement of the ejector lever 3, the ratio between the length of the power arm to the length of the load arm (lever ratio power arm / load arm) is significantly reduced as a result of the displacement of the support point 5, e.g. at least by a factor of 1.5. It can also be seen that the ejector lever 3 executes a pure rolling movement on the rolling contour 4, i.e. there is essentially no sliding movement with respect to the rolling contour 4.

Die Figuren 4 bis 6 zeigen einen vergleichbaren Auswurf-Vorgang wie die Figuren 1 bis 3, wobei in den Figuren 4 bis 6 der Auswerferhebel 3 anders geformt ist. Die Figur 4 zeigt ansonsten den gleichen Zustand wie die Figur 1, die Figur 5 den gleichen Zustand wie die Figur 2, und die Figur 6 den gleichen Zustand wie die Figur 3.The Figures 4 to 6 show a comparable ejection process as the Figures 1 to 3 , where in the Figures 4 to 6 the ejector lever 3 is shaped differently. Otherwise, FIG. 4 shows the same state as that Figure 1 , the Figure 5 the same state as that Figure 2 , and the Figure 6 the same state as that Figure 3 .

Bei den Figuren 4 bis 6 ist der Auswerferhebel 3 als Winkelhebel ausgebildet, der dementsprechend einen abgewinkelten Hebelarm 30 aufweist. Der untere, vom manuellen Bedienelement 31 entfernte Abschnitt des Hebelarms 30 ist vergleichbar wie bei der Ausführungsform der Figuren 1 bis 3 angeordnet und dient ebenfalls zum Abrollen bei einer Verschwenkbewegung des Auswerferhebels 3 auf der Abrollkontur 4. Ein dazu abgewinkelt verlaufender Abschnitt des Hebelarms 30, der an dem manuellen Betätigungselement 31 endet, verläuft bis zur Oberseite des Bauelementes 2. Auf diese Weise kann der Auswerferhebel 3 bequemer von oben her am manuellen Betätigungselement 31 betätigt werden.Both Figures 4 to 6 the ejector lever 3 is designed as an angle lever which accordingly has an angled lever arm 30. The lower section of the lever arm 30 remote from the manual operating element 31 is comparable to that in the embodiment of FIG Figures 1 to 3 arranged and also serves to roll during a pivoting movement of the ejector lever 3 on the rolling contour 4. A section of the lever arm 30 that is angled for this and ends at the manual actuating element 31 extends to the top of the component 2. In this way, the ejector lever 3 can be more convenient can be actuated from above on the manual actuating element 31.

Im Unterschied zu den Figuren 1 bis 3 ist bei den Figuren 4 bis 6 der Auswerferhebel 3 zusätzlich über eine Halteachse 33 in einem Langloch 12 des Isolierstoffgehäuses geführt, wie insbesondere die Figur 8 verdeutlicht. Durch diese Führung mit der Halteachse 33 kann der Auswerferhebel 3 sicher an dem Isolierstoffgehäuse 11 fixiert werden. Hierbei bildet aber die Halteachse 33 nicht die Verschwenkachse bei einer Verschwenkbewegung des Auswerferhebels 3 bei einem Auswurf-Vorgang. Die Verschwenkachse wird weiterhin durch den wandernden Auflagerpunkt 5 bestimmt.In contrast to the Figures 1 to 3 is with the Figures 4 to 6 the ejector lever 3 is additionally guided via a holding shaft 33 in an elongated hole 12 of the insulating material housing, such as in particular the Figure 8 made clear. As a result of this guidance with the holding shaft 33, the ejector lever 3 can be securely fixed on the insulating material housing 11. Here, however, the holding axis 33 does not form the pivot axis during a pivoting movement of the ejector lever 3 during an ejection process. The pivot axis is also determined by the moving support point 5.

Während bei den Ausführungsformen der Figuren 1 bis 6 der Hebel 30 eine linear verlaufende Lagerungskontur 34 aufweist, mit der der Auswerferhebel 3 auf der Abrollkontur 4 aufgelagert ist, und dementsprechend die Abrollkontur 4 relativ zum Auswerferhebel 3 konvex ausgestaltet ist, z.B. mit konstanter Krümmung, zeigt die Figur 7 eine Ausführungsform, bei der eine Abrollkontur 4 mit linearem Verlauf realisiert ist. Dementsprechend weist die Lagerungskontur 34 des Auswerferhebels 3 einen relativ zur Abrollkontur 4 konvexen Verlauf auf. In beiden Fällen ist die gewünschte Abrollbewegung des Auswerferhebels 3 auf der Abrollkontur 4 möglich.While in the embodiments of Figures 1 to 6 the lever 30 has a linear bearing contour 34 with which the ejector lever 3 is supported on the rolling contour 4, and accordingly the rolling contour 4 is configured convex relative to the ejector lever 3, for example with a constant curvature, is shown in FIG figure 7th an embodiment in which a rolling contour 4 is realized with a linear course. Accordingly, the bearing contour 34 of the ejector lever 3 has a convex course relative to the rolling contour 4. In both cases, the desired rolling movement of the ejector lever 3 on the rolling contour 4 is possible.

Wie in den Figuren dargestellt, läuft der Hebelarm 30 unterhalb des Bauelements 2 einseitig an den Kontaktelementen 21 vorbei, so dass die Verschwenkbewegung des Hebelarms 30 durch die Kontaktelemente 21 nicht behindert wird. Alternativ kann dieser Abschnitt des Hebelarms 30 auch gabelförmig ausgestaltet sein, so dass die Kontaktelemente 21 sich dann in einem Freiraum zwischen den Gabeln des Hebelarms befinden können.As shown in the figures, the lever arm 30 runs below the component 2 on one side past the contact elements 21, so that the pivoting movement of the lever arm 30 is not hindered by the contact elements 21. Alternatively, this section of the lever arm 30 can also be configured in the shape of a fork, so that the contact elements 21 can then be located in a free space between the forks of the lever arm.

Anhand der Figur 8 ist noch einmal die Fixierung des Auswerferhebels 3 über die Halteachse 33 in dem Langloch 12 des Isolierstoffgehäuses 11 verdeutlicht. Zudem ist erkennbar, dass das elektrische Gerät 1 z.B. ein Reiheneinbaugerät sein kann, wie es in der elektrischen Installationstechnik eingesetzt wird, z.B. eine Reihenklemme. Das elektrische Gerät 1 kann, z.B. an seinem Isolierstoffgehäuse 11, Tragschienen-Befestigungselemente 13 aufweisen, über die das elektrische Gerät 1 an einer Tragschiene der elektrischen Installationstechnik, z.B. an einer Hutschiene, befestigt werden kann.Based on Figure 8 the fixing of the ejector lever 3 via the holding shaft 33 in the elongated hole 12 of the insulating material housing 11 is illustrated once again. In addition, it can be seen that the electrical device 1 can, for example, be a modular installation device, such as is used in electrical installation technology, for example a series terminal. The electrical device 1 can have mounting rail fastening elements 13, for example on its insulating material housing 11, by means of which the electrical device 1 can be attached to a mounting rail of electrical installation technology, for example on a top hat rail.
