Description

Die Erfindung richtet sich auf eine Verriegelungseinrichtung zum Befestigen eines Anschlusselementes an einem Gehäuse einer Steckeranordnung. Ferner richtet sich die Erfindung auf eine derartige Steckeranordnung.The invention is directed to a locking device for fastening a connection element to a housing of a plug arrangement. Furthermore, the invention is directed to such a connector assembly.

Steckeranordnungen, welche insbesondere für Solarmodule verwendet werden, weisen hohe Sicherheitsanforderungen an die Befestigung eines Anschlusselementes, insbesondere eines Steckers, auf. Ein wichtiges Kriterium hierbei ist, dass die Anschlusselemente nicht ohne die Hilfe eines Werkzeuges lösbar sein dürfen.Plug assemblies, which are used in particular for solar modules, have high safety requirements for the attachment of a connection element, in particular a plug on. An important criterion here is that the connection elements may not be solvable without the aid of a tool.

Der Erfindung liegt daher die Aufgabe zu Grunde, eine Lösung zu schaffen, mittels welcher die Erfüllung der hohen Sicherheitsanforderungen weiter verbessert werden kann. Zudem liegt der Erfindung die Aufgabe zu Grunde, die Montage eines Verriegelungselementes an einem Gehäuse zu vereinfachen und Montagefehler weitestgehend zu verhindern.The invention is therefore based on the object to provide a solution by means of which the fulfillment of the high security requirements can be further improved. In addition, the invention is based on the object to simplify the mounting of a locking element on a housing and prevent assembly errors as far as possible.

Bei einer Verriegelungseinrichtung der eingangs näher bezeichneten Art erfolgt die Lösung der Aufgabe erfindungsgemäß dadurch, dass die Verriegelungseinrichtung ein im Wesentlichen U-förmig ausgebildetes Federelement aufweist, welches einen ersten Schenkel und einen in einem Ruhezustand des Federelementes im Wesentlichen parallel zu dem ersten Schenkel angeordneten zweiten Schenkel aufweist, wobei der erste Schenkel eine größere Länge aufweist als der zweite Schenkel.In a locking device of the type described in more detail, the object is achieved according to the invention in that the locking device has a substantially U-shaped spring element which has a first leg and a second leg arranged substantially parallel to the first leg in an idle state wherein the first leg has a greater length than the second leg.

Ferner erfolgt die Lösung der Aufgabe bei einer Steckeranordnung der eingangs näher bezeichneten Art erfindungsgemäß dadurch, dass die Steckeranordnung ein Gehäuse umfasst mit einer Durchführöffnung zum Durchführen eines Verriegelungselementes eines Anschlusselementes, wobei im Bereich der Durchführöffnung eine nach einem der Ansprüche 1 bis 7 ausgebildete Verriegelungseinrichtung anordbar ist, wobei benachbart zu der Durchführöffnung an dem Gehäuse ein Begrenzungselement angeordnet ist, welches als eine Positionierhilfe für das Federelement der Verriegelungseinrichtung dient.Furthermore, the object is achieved in a connector assembly of the type described in more detail according to the invention in that the connector assembly includes a housing having a passage opening for passing a locking element of a connection element, wherein in the region of the passage opening formed according to one of claims 1 to 7 locking device can be arranged , wherein adjacent to the passage opening on the housing, a limiting element is arranged, which serves as a positioning aid for the spring element of the locking device.

Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments and advantageous developments of the invention are specified in the dependent claims.

Das Federelement dient dazu, das Verriegelungselement eines Anschlusselementes, welches durch eine Durchführöffnung des Gehäuses hindurchgeführt ist, sicher an dem Gehäuse zu befestigen, so dass das Anschlusselement nicht ohne die Zuhilfenahme eines Werkzeuges von dem Gehäuse gelöst werden kann. Das Anschlusselement kann ein Stecker, insbesondere ein mehrpoliger Solarstecker sein, welcher neben seinen Anschlusskontakten vorzugsweise zwei Verriegelungselemente aufweist, die beispielsweise in Form von Stiften ausgebildet sein können, die von der Stirnfläche bzw. dem Steckgesicht des Anschlusselementes abstehen. Die Verriegelungseinrichtung ist als eine Schenkelfeder in Form eines im Wesentlichen U-förmigen Federelementes ausgebildet, welches zwei in einem Ruhezustand des Federelementes im Wesentlichen parallel zueinander verlaufende Schenkel aufweist. Der Ruhezustand des Federelementes ist der Zustand, bei dem das Federelement nicht, beispielsweise durch ein Werkzeug oder beim Befestigen des Federelementes an dem Gehäuse, betätigt wird. Vorzugsweise stellt der Ruhezustand den Zustand dar, bei welchem eine Verriegelung des Verriegelungselementes mittels des Federelementes ausgebildet ist. In diesem Zustand wird das Verriegelungselement zwischen den beiden Schenkeln des Federelementes geklemmt gehalten. Um die Montage des Federelementes an dem Gehäuse zu erleichten und Fehler bei der Montage zu verhindern, sind die beiden Schenkel des Federelementes unterschiedlich lang ausgebildet. An dem Gehäuse selber ist zudem benachbart zu der Durchführöffnung ein Begrenzungselement angeordnet, welches als eine Art Positionierhilfe für das Federelement dient. Das Begrenzungselement bestimmt den zur Verfügung stehenden Raum zum Positionieren des Federelementes an dem Gehäuse für einen der zwei Schenkel des Federelementes. Das Begrenzungselement ist dabei derart angeordnet, dass das Federelement nur derart an dem Gehäuse angeordnet werden kann, dass das Federelement ausschließlich mit seinem kürzeren Schenkel, in diesem Fall mit dem zweiten Schenkel, unmittelbar neben oder angrenzend zu dem Begrenzungselement angeordnet werden kann. Würde in diesen Bereich der längere Schenkel, in diesem Fall der erste Schenkel, eingesetzt werden, so würde dieser länger ausgebildete Schenkel das Begrenzungselement überlappen. Eine Positionierung des Federelementes mit dem längeren Schenkel ist in diesem Bereich nicht möglich. Das Federelement kann dadurch nur von einer möglichen Richtung aus an dem Gehäuse angeordnet werden. Das Begrenzungselement kann beispielsweise in Form eines von dem Gehäuse abstehenden Steges ausgebildet sein.The spring element serves to secure the locking element of a connection element, which is passed through a passage opening of the housing, securely fastened to the housing, so that the connection element can not be detached from the housing without the aid of a tool. The connecting element may be a plug, in particular a multi-pole solar plug, which in addition to its connection contacts preferably has two locking elements, which may be formed for example in the form of pins which protrude from the end face or the mating face of the connection element. The locking device is designed as a leg spring in the form of a substantially U-shaped spring element, which has two limbs that run essentially parallel to one another in a resting state of the spring element. The idle state of the spring element is the state in which the spring element is not, for example by a tool or at Attaching the spring element to the housing, is operated. Preferably, the rest state represents the state in which a locking of the locking element is formed by means of the spring element. In this state, the locking element is clamped between the two legs of the spring element. In order to facilitate the assembly of the spring element on the housing and to prevent errors during assembly, the two legs of the spring element are formed differently long. On the housing itself, a limiting element is additionally arranged adjacent to the passage opening, which serves as a kind of positioning aid for the spring element. The limiting element determines the available space for positioning the spring element on the housing for one of the two legs of the spring element. The limiting element is arranged such that the spring element can only be arranged on the housing such that the spring element can be arranged exclusively with its shorter leg, in this case with the second leg, immediately adjacent or adjacent to the limiting element. If the longer limb, in this case the first limb, were used in this region, then this longer limb would overlap the limiter. A positioning of the spring element with the longer leg is not possible in this area. The spring element can thereby be arranged on the housing only from a possible direction. The limiting element may be formed, for example, in the form of a web projecting from the housing.

Nach einer erfindungsgemäßen Ausgestaltung des Verriegelungselementes kann das Federelement eine erste Einführhilfe für ein zu befestigendes Verriegelungselement des Anschlusselementes aufweisen. Die Einführhilfe dient dazu, das Einführen des Verriegelungselementes in das Federelement, insbesondere in den Bereich zwischen den beiden Schenkeln des Federelementes zu erleichtern, um insbesondere unerwünschte Verhakungen und Schiefstellungen des Verriegelungselementes beim Einführen zu verhindern, so dass eine schnelle und sichere Befestigung des Verriegelungselementes an dem Gehäuse gewährleistet werden kann.According to an embodiment of the locking element according to the invention, the spring element may have a first insertion aid for a locking element of the connection element to be fastened. The insertion aid is used to facilitate the insertion of the locking element in the spring element, in particular in the region between the two legs of the spring element, in particular to prevent unwanted entanglements and misalignment of the locking element during insertion, so that a fast and secure attachment of the locking element can be ensured on the housing can.

Ferner kann es vorzugsweise vorgesehen sein, dass das Federelement eine zweite Einführhilfe zum Einführen eines Werkzeuges, mit welchem die an dem Verriegelungselement anliegenden Schenkel von dem Verriegelungselement gelöst werden können, so dass das Verriegelungselement von dem Federelement gelöst werden kann, um das Anschlusselement von dem Gehäuse entfernen zu können, aufweist.Furthermore, it can preferably be provided that the spring element has a second insertion aid for inserting a tool, with which the legs resting on the locking element can be released from the locking element, so that the locking element can be released from the spring element to the connection element of the housing to be able to remove.

Gemäß einer weiter bevorzugten Ausgestaltung der Verriegelungseinrichtung ist die erste Einführhilfe gegenüberliegend zu der zweiten Einführhilfe an dem Federelement ausgebildet. Dies ermöglicht ein leichteres Einführen eines Werkzeuges in das Federelement, wenn das Werkzeug entgegengesetzt zur Einführrichtung des Verriegelungselementes in einen durch die beiden Schenkel des Federelementes ausgebildeten Innenraum des Federelementes zum Lösen des Federelementes eingeführt wird.According to a further preferred embodiment of the locking device, the first insertion aid is formed opposite to the second insertion aid on the spring element. This allows easier insertion of a tool in the spring element, when the tool is introduced opposite to the direction of insertion of the locking element in a formed by the two legs of the spring element interior of the spring element for releasing the spring element.

Weiter ist es vorzugsweise vorgesehen, dass die erste Einführhilfe und/oder die zweite Einführhilfe in Form eines jeweils an dem ersten Schenkel und an dem zweiten Schenkel gebogen ausgebildeten Kantenbereichs ausgebildet ist. Der gebogen ausgebildete Kantenbereich ist dabei jeweils an einer Längsseitenfläche der Schenkel ausgebildet. Dieser gebogen ausgebildete Kantenbereich, welcher vorzugsweise die Form einer Lippe aufweist, ist dabei vorzugsweise von einem durch den ersten Schenkel und den zweiten Schenkel ausgebildeten Innenraum des Federelementes weg gebogen, so dass der gebogen ausgebildete Kantenbereich von dem Federelement nach außen hin absteht. Der gebogen ausgebildete Kantenbereich ermöglicht eine Führung des Verriegelungselementes und/oder des Werkzeuges unmittelbar in den Innenraum des Federelementes.Furthermore, it is preferably provided that the first insertion aid and / or the second insertion aid is designed in the form of an edge region that is bent in each case on the first leg and on the second leg. The bent edge region is in each case formed on a longitudinal side surface of the legs. This bent edge region, which preferably has the shape of a lip, is preferably bent away from an inner space formed by the first leg and the second leg of the spring element, so that the bent edge portion protrudes from the spring element to the outside. The bent edge portion allows a guide of the locking element and / or the tool directly into the interior of the spring element.

Um die Befestigung des Verriegelungselementes an dem Federelement möglichst sicher auszugestalten, ist es weiter bevorzugt vorgesehen, dass das Federelement einen Rastbereich zum Hinterrasten eines zu befestigenden Verriegelungselementes des Anschlusselementes aufweist. Der Rastbereich dient zudem als eine Art Zugentlastung für das an dem Rastbereich befestigte Verriegelungselement.In order to design the fastening of the locking element on the spring element as securely as possible, it is further preferred that the spring element has a latching area for locking behind a locking element to be fastened of the connecting element. The latching area also serves as a kind of strain relief for the locking element attached to the locking element.

Der Rastbereich ist dabei bevorzugt in Form eines jeweils an dem ersten Schenkel und an dem zweiten Schenkel ausgebildeten scharfen Kantenbereichs ausgebildet. Scharfer Kantenbereich bedeutet hierbei, dass der Kantenbereich eine möglichst geringe Dicke aufweist, so dass ein eingeführtes Verriegelungselement das Federelement in diesem Kantenbereich möglichst leicht hintergreifen und daran festrasten kann. Beispielsweise kann dieser Kantenbereich mit einer Abschrägung oder einer Phase zur Reduzierung der Dicke des Schenkels in diesem Bereich versehen sein. Es ist aber auch möglich, dass der scharfe Kantenbereich die gleich Dicke aufweist, wie die Mitte des Schenkels, an welchem der Kantenbereich ausgebildet ist.The latching region is preferably formed in the form of a sharp edge region respectively formed on the first leg and on the second leg. Sharp edge region here means that the edge region has the smallest possible thickness, so that an inserted locking element can engage behind the spring element in this edge region as easily as possible and can lock on it. For example, this edge portion may be provided with a chamfer or a phase for reducing the thickness of the leg in this area. However, it is also possible for the sharp edge region to have the same thickness as the middle of the limb on which the edge region is formed.

Um das Öffnen des Federelementes mittels eines Werkzeuges zu erleichtern, ist es gemäß einer erfindungsgemäßen Weiterbildung der Steckeranordnung vorgesehen, dass das Gehäuse eine benachbart zu der Durchführöffnung ausgebildete Werkzeugeinführöffnung aufweist. Dies ermöglicht insbesondere, dass die Einführrichtung des Werkzeuges gleich zu der Einführrichtung des Verriegelungselementes ausgebildet ist. Zudem ermöglicht die Werkzeugeinführöffnung eine gezielte Führung des Werkzeuges hin zu dem Federelement, um ein schnelles und gezieltes Öffnen der Verriegelung mittels eines Werkzeuges, beispielsweise eines Schraubendrehers, zu ermöglichen.In order to facilitate the opening of the spring element by means of a tool, it is according to an inventive Further development of the connector assembly provided that the housing has a tool insertion opening formed adjacent to the passage opening. This allows in particular that the insertion of the tool is formed equal to the insertion direction of the locking element. In addition, the tool insertion opening allows a targeted guidance of the tool towards the spring element in order to allow a quick and targeted opening of the locking means of a tool, such as a screwdriver.

Um ein falsches Einführen des Verriegelungselementes in die Werkzeugeinführöffnung bzw. des Werkzeuges in die Durchführöffnung zu verhindern, weist die Werkzeugeinführöffnung vorzugsweise eine in ihrer Form unterschiedlich zu der Durchführöffnung ausgebildete Umfangsfläche auf.In order to prevent incorrect insertion of the locking element into the tool insertion opening or the tool into the lead-through opening, the tool insertion opening preferably has a peripheral surface which is different in shape from the lead-through opening.

Das Gehäuse 1 ist hierbei in einem geöffneten Zustand gezeigt. Fig. 1 zeigt dabei die Steckeranordnung mit einem daran angeordneten Anschlusselement 2. Fig. 2 zeigt die Steckeranordnung ohne ein daran angeordnetes Anschlusselement.In Fig. 1 and Fig. 2 schematically is a connector assembly according to the invention with a housing 1 and arranged on the housing 1 connecting element 2 in the form of a plug, in particular a multi-pole solar plug shown. The housing 1 is shown here in an open state. Fig. 1 shows the plug arrangement with a connecting element 2 arranged thereon. Fig. 2 shows the plug assembly without a connection element arranged thereon.

Das Anschlusselement 2 weist zwei jeweils seitlich neben seinen Anschlusskontakten 3a - 3d, wie sie in Fig. 2 zu erkennen sind, angeordnete Verriegelungselemente 4 auf, mit welchen das Anschlusselement 2 an dem Gehäuse 1 befestigt werden kann. Die Verriegelungselemente 4 sind in Form von Stiften ausgebildet, welche bei der hier gezeigten Ausführungsform eine kreuzförmige Querschnittsfläche aufweisen. An ihrem freien Endbereich weisen die Verriegelungselemente 4 ein oder mehrere, vorzugsweise zwei gegenüberliegend ausgebildete, Rastnasen 5 auf, welche hinter einer Hinterschneidung einrasten können.The connection element 2 has two each laterally next to its connection contacts 3a - 3d, as shown in FIG Fig. 2 can be seen, arranged locking elements 4, with which the connection element 2 can be attached to the housing 1. The locking elements 4 are in the form of pins, which in the embodiment shown here have a cross-shaped cross-sectional area. At its free end region, the locking elements 4 have one or more, preferably two oppositely formed, locking lugs 5, which can engage behind an undercut.

Zur Befestigung des Anschlusselementes 2 an dem Gehäuse 1 werden die Verriegelungselemente 4 durch jeweils eine an dem Gehäuse 1 ausgebildete Durchführöffnung 6 hindurchgeführt, wie sie in Fig. 2 zu erkennen ist. Die Form der Umfangsfläche der Durchführöffnung 6 ist dabei an die Form der Querschnittsfläche des Verriegelungselementes 4 angepasst, so dass bei der hier gezeigten Ausführungsform die Umfangsfläche der Durchführöffnung 6 kreuzförmig ausgebildet ist.For attachment of the connection element 2 to the housing 1, the locking elements 4 by one at the housing 1 formed through opening 6 passed, as in Fig. 2 can be seen. The shape of the circumferential surface of the passage opening 6 is adapted to the shape of the cross-sectional area of the locking element 4, so that in the embodiment shown here, the peripheral surface of the passage opening 6 is formed cross-shaped.

Zum Befestigen der Verriegelungselemente 4 an dem Gehäuse 1 sind zwei Federelemente 7 einer Verriegelungseinrichtung vorgesehen, welche mittels eines an dem Gehäuse 1 ausgebildeten Halteelementes 8 an dem Gehäuse 1 befestigt werden können. Die Federelemente 7 sind jeweils U-förmig ausgebildet und weisen einen ersten Schenkel 9a und einen in einem Ruhezustand des Federelementes 7, wie er in Fig. 1 und 2 gezeigt ist, im Wesentlichen parallel zu dem ersten Schenkel 9a angeordneten zweiten Schenkel 9b auf. Die beiden Schenkel 9, 9b weisen eine unterschiedliche Länge auf, wobei bei der hier gezeigten Ausführungsform der erste Schenkel 9a eine größere Länge aufweist als der zweite Schenkel 9b.For fastening the locking elements 4 to the housing 1, two spring elements 7 of a locking device are provided which can be fastened to the housing 1 by means of a holding element 8 formed on the housing 1. The spring elements 7 are each U-shaped and have a first leg 9a and one in a resting state of the spring element 7, as in Fig. 1 and 2 is shown, arranged substantially parallel to the first leg 9a second leg 9b. The two legs 9, 9b have a different length, wherein in the embodiment shown here, the first leg 9a has a greater length than the second leg 9b.

An dem Gehäuse 1 ist benachbart zu der Durchführöffnung 6 ein Begrenzungselement 10 in Form eines Steges ausgebildet, welcher sich über einen Teilbereich der Länge der Durchführöffnung 6 erstreckt, so dass sich das Begrenzungselement 10 bei der hier gezeigten Ausführungsform über die untere Kante 13 der Durchführöffnung 6 erstreckt, jedoch nicht im Bereich der oberen Kante 12 der Durchführöffnung 6 ausgebildet ist. Durch das Begrenzungselement 10 wird der mögliche Positionierungsbereich einer der beiden Schenkel 9a, 9b des Federelementes 7 ausgehend von dem Halteelement 8, an welchem das Federelement 7 mit seiner U-förmigen Biegung 11 anliegt, begrenzt. Die Begrenzung ist dabei gerade so groß, dass in diesen Positionierungsbereich nur der Schenkel 9b des Federelementes 7 mit der geringeren Länge passt und eingefügt werden kann. Dadurch wird die mögliche Befestigungsrichtung des Federelementes 7 an dem Gehäuse 1 festgelegt, eine falsche Montage des Federelementes 7 kann dadurch verhindert werden.On the housing 1 adjacent to the passage opening 6, a limiting element 10 is formed in the form of a web which extends over a portion of the length of the passage opening 6, so that the limiting element 10 in the embodiment shown here on the lower edge 13 of the passage opening. 6 extends, but is not formed in the region of the upper edge 12 of the passage opening 6. By the limiting element 10 is the possible positioning range of one of the two legs 9a, 9b of the spring element 7, starting from the holding element 8, on which the spring element 7 with its U-shaped bend 11th is limited. The limitation is just so great that in this positioning range only the leg 9b of the spring element 7 with the shorter length fits and can be inserted. Thereby, the possible attachment direction of the spring element 7 is fixed to the housing 1, an incorrect installation of the spring element 7 can be prevented.

Eine detailliertere Darstellung des Federelementes 7 ist in Fig. 3 und Fig. 4 gezeigt. Zur Vereinfachung des Einführens eines Verriegelungselementes 4 in einen durch die beiden Schenkel 9a, 9b des Federelementes 7 ausgebildeten Innenraum, in welchem das Verriegelungselement 4 eingeklemmt gehalten wird, weist das Federelement 7 eine erste Einführhilfe 14 auf. Die erste Einführhilfe 14 ist in Form eines gebogen ausgebildeten Kantenbereiches sowohl an dem ersten Schenkel 9a als auch an dem zweiten Schenkel 9b ausgebildet. Die beiden gebogen ausgebildeten Kantenbereiche der ersten Einführhilfe 14 sind an den beiden Schenkeln 9a, 9b derart ausgebildet, dass sie sich gegenüberliegen. Die erste Einführhilfe 14 ist bei der hier gezeigten Ausführungsform derart ausgebildet, dass sie sich über den Bereich der Durchführöffnung 6 als auch über eine benachbart zu der Durchführöffnung 6 angeordnete Werkzeugeinführöffnung 15 erstreckt, wenn das Federelement 7 an dem Gehäuse 1 positioniert ist. Somit kann die erste Einführhilfe 14 hier auch zur Führung eines über die Werkzeugeinführöffnung 15 in den Innenraum des Federelementes 7 eingeführten Werkzeuges dienen. Ist das Federelement 7 an dem Gehäuse 1 positioniert, liegt die erste Einführhilfe 14 unmittelbar an dem Gehäuse 1 an.A more detailed illustration of the spring element 7 is shown in FIG Fig. 3 and Fig. 4 shown. To simplify the insertion of a locking element 4 in a formed by the two legs 9a, 9b of the spring element 7 interior, in which the locking element 4 is held clamped, the spring element 7 has a first insertion aid 14. The first insertion aid 14 is formed in the form of a bent edge region both on the first leg 9a and on the second leg 9b. The two bent edge regions of the first insertion aid 14 are formed on the two legs 9a, 9b so that they face each other. In the embodiment shown here, the first insertion aid 14 is designed such that it extends over the region of the through-opening 6 as well as over a tool insertion opening 15 arranged adjacent to the through-opening 6 when the spring element 7 is positioned on the housing 1. Thus, the first insertion aid 14 can also serve to guide a tool introduced via the tool insertion opening 15 into the interior of the spring element 7. If the spring element 7 is positioned on the housing 1, the first insertion aid 14 rests directly against the housing 1.

Zusätzlich zu der ersten Einführhilfe 14 weist das Federelement 7 eine zweite Einführhilfe 16 auf, welche der ersten Einführhilfe 16 gegenüberliegend an den beiden Schenkeln 9a, 9b angeordnet ist. Die zweite Einführhilfe 16 ist ebenso wie die erste Einführhilfe 14 in Form eines gebogen ausgebildeten Kantenbereiches sowohl an dem ersten Schenkel 9a als auch an dem zweiten Schenkel 9b ausgebildet. Die beiden gebogen ausgebildeten Kantenbereiche der zweiten Einführhilfe 16 sind an den beiden Schenkeln 9a, 9b derart ausgebildet, dass sie sich gegenüberliegen. Im Gegensatz zur ersten Einführhilfe 14 erstreckt sich die zweite Einführhilfe 16 jedoch nur über den Bereich der Werkzeugeinführöffnung 15 und nicht über den Bereich der Durchführöffnung 6, wenn das Federelement 7 an dem Gehäuse 1 positioniert ist. Ist das Federelement 7 an dem Gehäuse 1 positioniert, ist die zweite Einführhilfe 16 an dem Kantenbereich des Federelementes 7 bzw. der Schenkel 9a, 9b ausgebildet, welcher von dem Gehäuse 1 wegzeigt. Die zweite Einführhilfe 16 dient zur Führung eines Werkzeuges in den Innenraum des Federelementes 7, wenn das Werkzeug nicht über die Werkzeugeinführöffnung 15, sondern über eine entgegengesetzt zur Einsteckrichtung der Verriegelungselemente 4 in den Innenraum des Federelementes 7 zum Öffnen des Federelementes 7 geführt wird.In addition to the first insertion aid 14, the spring element 7 has a second insertion aid 16, which is the first insertion aid 16 opposite to the two legs 9a, 9b is arranged. The second insertion aid 16, like the first insertion aid 14 in the form of a bent edge region, is formed both on the first leg 9a and on the second leg 9b. The two bent edge regions of the second insertion aid 16 are formed on the two legs 9a, 9b in such a way that they face each other. In contrast to the first insertion aid 14, however, the second insertion aid 16 extends only over the region of the tool insertion opening 15 and not over the region of the through opening 6 when the spring element 7 is positioned on the housing 1. If the spring element 7 is positioned on the housing 1, the second insertion aid 16 is formed on the edge region of the spring element 7 or the legs 9a, 9b which points away from the housing 1. The second insertion aid 16 serves to guide a tool into the interior of the spring element 7 when the tool is not guided over the tool insertion opening 15, but via an opposite direction of insertion of the locking elements 4 in the interior of the spring element 7 for opening the spring element 7.

Die gebogen ausgebildeten Kantenbereiche der ersten EinfĂĽhrhilfe 14 und der zweiten EinfĂĽhrhilfe sind jeweils in Form einer Lippe ausgebildet, welche von dem Innenraum des Federelementes 15 weg gebogen ist, so dass die gebogen ausgebildeten Kantenbereiche von dem Federelement 7 nach auĂźen hin abstehen.The arcuately formed edge regions of the first insertion aid 14 and the second insertion aid are each in the form of a lip, which is bent away from the interior of the spring element 15, so that the bent edge regions protrude from the spring element 7 to the outside.

Benachbart zu der zweiten Einführhilfe 16 ist an dem ersten Schenkel 9a und an dem zweiten Schenkel 9b des Federelementes 7 ein Rastbereich 17 ausgebildet, an welchem das Verriegelungselement 4 mit seinen Rastnasen 5 hintergreifen bzw. verrasten kann. Der Rastbereich 17 ist in Form eines scharfen Kantenbereiches an dem ersten Schenkel 9a und an dem zweiten Schenkel 9b ausgebildet. Im Bereich des Rastbereiches 17 weist der Kantenbereich der Schenkel 9a, 9b eine geringere Dicke als der Kantenbereich der Schenkel 9a, 9b im Bereich der ersten und zweiten Einführhilfe 14, 16 auf. Im Bereich der ersten und zweiten Einführhilfe 14, 16 kann keine Verrastung erfolgen, da aufgrund der hier ausgebildeten gebogenen Kantenbereiche die Dicke der Kantenbereiche zu groß ist, so dass die Rastnasen 5 des Verriegelungselementes 4 hier nicht einrasten bzw. hintergreifen können.Adjacent to the second insertion aid 16, a latching region 17 is formed on the first leg 9a and on the second leg 9b of the spring element 7, on which the locking element 4 with its latching noses. 5 can engage behind. The latching region 17 is formed in the form of a sharp edge region on the first leg 9a and on the second leg 9b. In the region of the latching region 17, the edge region of the legs 9a, 9b has a smaller thickness than the edge region of the legs 9a, 9b in the region of the first and second insertion aids 14, 16. In the region of the first and second insertion aid 14, 16, no latching can take place, since due to the curved edge regions formed here, the thickness of the edge regions is too great, so that the latching lugs 5 of the locking element 4 can not engage or engage behind.

Fig. 4 zeigt eine Darstellung des Federelementes 7, bei welcher die unterschiedlich lang ausgebildeten Schenkel 9a, 9b deutlich zu erkennen sind. Fig. 4 shows a representation of the spring element 7, in which the differently long legs 9a, 9b are clearly visible.

Um die Verriegelung bzw. die Verrastung des Verriegelungselementes 4 an dem Federelement 7 zu lösen, wird in den Innenraum des Federelementes 7 ein Werkzeug, beispielsweise ein Schraubendreher, eingeführt, hier nicht gezeigt, mittels welchem die Schenkel 9a, 9b des Federelementes 7 auseinander gedrückt werden, so dass das Verriegelungselement 4 von dem Rastbereich 17 gelöst werden kann und das Verriegelungselement 4 über die Durchführöffnung 6 von dem Gehäuse 1 abgezogen werden kann. Die Einführung des Werkzeuges erfolgt vorzugsweise über die Werkzeugeinführöffnung 15 an dem Gehäuse 1. Um ein falsches Einführen des Verriegelungselementes 4 in die Werkzeugeinführöffnung 15 bzw. des Werkzeuges in die Durchführöffnung 6 zu verhindern, weist die Werkzeugeinführöffnung 15 vorzugsweise eine in ihrer Form unterschiedlich zu der Durchführöffnung 6 ausgebildete Umfangsfläche auf, indem die Umfangsfläche der Durchführöffnung 6 kreuzförmig und die Umfangsfläche der Werkzeugeinführöffnung 15 kreisrund ausgebildet ist.In order to release the locking or the locking of the locking element 4 on the spring element 7, a tool, such as a screwdriver, introduced, not shown here, by means of which the legs 9a, 9b of the spring element 7 are pressed apart in the interior of the spring element 7 , so that the locking element 4 can be released from the latching portion 17 and the locking element 4 can be withdrawn via the passage opening 6 of the housing 1. The insertion of the tool preferably takes place via the tool insertion opening 15 on the housing 1. In order to prevent incorrect insertion of the locking element 4 into the tool insertion opening 15 or the tool into the lead-through opening 6, the tool insertion opening 15 preferably has a shape different from the lead-through opening 6 formed peripheral surface by the peripheral surface of the Through opening 6 cross-shaped and the peripheral surface of the tool insertion opening 15 is formed circular.
