Description

Die Erfindung betrifft einen elektrischen Verbinder zum Anschluss von wenigstens zwei elektrischen Kontaktelementen mit einem ersten und einem zweiten Verbinderteil, die zu einer Verbindergesamtheit zusammensteckbar sind. Weiterhin betrifft die Erfindung ein elektrisches Verbindungssystem mit einem solchen elektrischen Verbinder und ein Verfahren zur Bildung eines elektrischen Verbindungssystems.The invention relates to an electrical connector for connecting at least two electrical contact elements with a first and a second connector part, which can be plugged together to form a connector. Furthermore, the invention relates to an electrical connection system with such an electrical connector and a method for forming an electrical connection system.

Elektrische Verbinder werden insbesondere im automobilen Bereich zum Anschluss von mehreren metallischen Kontaktelementen verwendet. Die elektrischen Kontaktelemente sind zum Beispiel an den Enden von Drähten eines Kabelbaumes angeordnet und werden in dem elektrischen Verbinder zusammengefasst, um eine Einheit zu bilden, die zum Beispiel wie ein Stecker oder ein Kontaktterminal eingesetzt werden kann.Electrical connectors are used in particular in the automotive sector for connecting a plurality of metallic contact elements. The electrical contact elements are arranged, for example, at the ends of wires of a wire harness and are combined in the electrical connector to form a unit that can be used, for example, like a plug or a contact terminal.

EP 1241738 A2 , die als nächstliegender Stand der Technik ausgesehen wird, beschreibt einen elektrischen Verbinder, der aus einem ersten und einem zweiten Verbinderteil zusammensteckbar ist. Jedes der Verbinderteile weist mehrere Aufnahmen zum Einstecken jeweils eines elektrischen Kontaktelementes auf. Die Aufnahmen weisen jeweils eine seitliche Öffnung auf, in die ein Vorsprungselement derart eingreifen kann, dass es in die Aufnahmen eingesteckte Kontaktelemente in der jeweiligen Aufnahme hält. Dabei umfasst das erste Verbinderteil ein erstes Vorsprungselement, das beim Zusammenstecken der beiden Verbinderteile in die seitliche Öffnung der Aufnahmen des zweiten Verbinderteils eingreift und in dessen Aufnahmen eingesteckte Kontaktelemente fixiert. EP 1241738 A2 , which is considered to represent the closest prior art, describes an electrical connector which is mated from a first and a second connector part. Each of the connector parts has a plurality of receptacles for plugging in each case an electrical contact element. The receptacles each have a lateral opening into which a projection element can engage such that it holds in the receptacles inserted contact elements in the respective recording. In this case, the first connector part comprises a first projection element, which engages in the mating of the two connector parts in the lateral opening of the receptacles of the second connector part and fixed in the receptacles inserted contact elements.

Bei der bekannten Lösung weist das zweite Verbinderteil ein zweites Vorsprungselement auf, das beim Zusammenstecken der beiden Verbinderteile in die seitliche Öffnung der Aufnahmen des ersten Verbinderteils eingreift. Jedem der Verbinderteile ist bei der bekannten Lösung also ein Vorsprungselement zugeordnet, das in die seitliche Öffnung der Aufnahmen des jeweils anderen Verbinderteils "reziprok" eingreift um die dort aufgenommenen Kontaktelemente zu halten. Zum Fixieren der Kontaktelemente in den Aufnahmen greifen die Vorsprungselemente durch die seitlichen Öffnungen der Aufnahmen hindurch in die seitlichen Ausnehmungen der Kontaktelemente ein. Die Fixierung der einzelnen Kontaktelemente geschieht dabei also bei allen Kontaktelementen beim Zusammensteckprozess. Vor dem Zusammensteckprozess und während des Zusammensteckens sind die Kontaktelemente in den Aufnahmen lose.In the known solution, the second connector part has a second projection element, which engages in the mating of the two connector parts in the lateral opening of the receptacles of the first connector part. Each of the connector parts is assigned a projection element in the known solution, which "reciprocally" engages in the lateral opening of the receptacles of the respective other connector part to hold the contact elements received there. For fixing the contact elements in the receptacles, the projection elements engage through the lateral openings of the receptacles into the lateral recesses of the contact elements. The fixation of the individual contact elements thus takes place in all contact elements during the assembly process. Before the mating process and during mating, the contact elements in the recordings are loose.

Ein solcher Verbinder ist auch aus US 5,643,015 bekannt.Such a connector is also off US 5,643,015 known.

Aufgabe der vorliegenden Erfindung ist es, den Zusammensteckprozess sicher zu gestalten und wenigstens bei einem Teil der Kontaktelemente sicherzustellen, dass sie sich während des Zusammensteckprozesses nicht aus den Aufnahmen lösen können.Object of the present invention is to make the assembly process safe and ensure at least a portion of the contact elements that they can not be detached from the recordings during the Zusammensteckprozesses.

Diese Aufgabe wird mit einem elektrischen Verbinder mit den Merkmalen des Anspruches 1, einem elektrischen Verbindungssystem mit den Merkmalen des Anspruches 9 und ein Verfahren zur Bildung eines elektrischen Verbindungssystems mit den Merkmalen des Anspruches 11 gelöst. Unteransprüche sind auf bevorzugte Ausgestaltungen gerichtet.This object is achieved with an electrical connector having the features of claim 1, an electrical connection system having the features of claim 9 and a method of forming an electrical connection system having the features of claim 11. Subclaims are directed to preferred embodiments.

Bei einem erfindungsgemäßen Verbinder ist das zweite Vorsprungselement, das zum Eingreifen in die seitliche Öffnung der wenigstens einen Aufnahme des ersten Verbinderteils vorgesehen ist, entweder an dem ersten Verbinderteil vorgesehen oder mit diesem derart verbindbar, dass es mit dem ersten Verbinderteil eine Einheit bildet, die zur Bildung der Verbindergesamtheit mit dem zweiten Verbinderteil zusammengesteckt werden kann. Bei dem erfindungsgemäßen Verbinder ist also nicht nur das erste Vorsprungselement, das in die seitliche Öffnung der wenigstens einen Aufnahme des zweiten Verbinderteils eingreifen soll, am ersten Verbinderteil vorgesehen, sondern auch das zweite Vorsprungselement, das in die seitliche Öffnung der wenigstens einen Aufnahme des ersten Verbinderteils eingreifen soll. Damit ist es möglich, dass nach dem Einführen der Kontaktelemente in die Aufnahmen des ersten Verbinderteils das zweite Vorsprungselement bereits vor dem Zusammensteckprozess der zwei Verbinderteile in die seitliche Öffnung der Aufnahmen des ersten Verbinderteils eingeführt werden kann um die Kontaktelemente in dessen Aufnahmen zu fixieren. Dadurch sind die Kontaktelemente in dem ersten Verbinderteil bereits vor dem Zusammensteckprozess fest fixiert und können während des Zusammensteckprozesses nicht mehr aus den Aufnahmen herausrutschen. So ist es möglich, dass das erste Verbinderteil zusammen mit den Kontaktelementen als eine Einheit mit dem zweiten Verbinderteil zusammengesteckt werden kann, ohne dass dabei noch auf die korrekte Position der Kontaktelemente in dem ersten Verbinderteil geachtet werden müsste. Dadurch wird der Kontrollaufwand während des Zusammensteckprozesses signifikant verringert und somit die Montage einfacher und kostengünstiger.In a connector according to the invention, the second projection element, which is provided for engaging in the lateral opening of the at least one receptacle of the first connector part, is either provided on the first connector part or can be connected to it in such a way that it forms a unit with the first connector part Education of the Connector entirety can be plugged together with the second connector part.

Thus, it is possible that after inserting the contact elements in the receptacles of the first connector part, the second projection element can be inserted before the Zusammensteckprozess the two connector parts in the lateral opening of the receptacles of the first connector part to fix the contact elements in its recordings. As a result, the contact elements in the first connector part are firmly fixed even before the assembly process and can no longer slip out of the receptacles during the assembly process. Thus, it is possible that the first connector part together with the contact elements can be plugged together as a unit with the second connector part, without having to pay attention to the correct position of the contact elements in the first connector part. As a result, the control effort during the assembly process is significantly reduced, making assembly easier and cheaper.

Durch Einführen des zweiten Vorsprungselementes in die seitliche Öffnung der Aufnahmen des ersten Verbinderteils werden diese Kontaktelemente darin fest fixiert. Weitere Kontaktelemente werden in die Aufnahmen des zweiten Verbinderteils eingeschoben, in deren seitliche Öffnung beim Zusammenstecken mit dem ersten Verbinderteil das erste Vorsprungselement des ersten Verbinderteils eingreift und die Kontaktelemente fixiert. Auf diese Weise entsteht eine Verbindergesamtheit, in der alle Kontaktelemente festgehalten werden. Durch die Fixierung der Kontaktelemente in den Aufnahmen des ersten Verbinderteils mit Hilfe des zweiten Vorsprungselements bereits bevor die Verbinderteile zusammengesteckt werden, ist gewährleistet, dass die Kontaktelemente aus den Aufnahmen des ersten Verbinderteils beim Zusammenstecken nicht mehr herausrutschen können.In an electrical connector according to the invention therefore first contact elements are introduced into the receptacles of the first connector part.

Zum Fixieren der Kontaktelemente in den Aufnahmen ist zum Beispiel vorgesehen, dass die Vorsprungselemente zum Festklemmen der Kontaktelemente oder zum Eingriff in gegebenenfalls vorgesehene seitliche Ausnehmungen in den Kontaktelementen ausgestaltet sind.For fixing the contact elements in the receptacles, it is provided, for example, that the projection elements are designed to clamp the contact elements or to engage in optionally provided lateral recesses in the contact elements.

Das zweite Vorsprungselement, das in die seitliche Öffnung der Aufnahmen des ersten Verbinderteils eingreifen soll um die in dessen Aufnahmen befindlichen Kontaktelemente zu halten, kann zum Beispiel in die seitliche Öffnung einschiebbar ausgestaltet sein. Besonders vorteilhaft ist es jedoch, wenn das zweite Vorsprungselement derart beweglich an dem ersten Verbinderteil vorgesehen ist, dass es in die seitliche Öffnung des ersten Verbinderteils einführbar ist, aber am ersten Verbinderteil in nicht lösbarer Weise befestigt ist. Durch die nicht lösbare, aber bewegliche Verbindung ist gewährleistet, dass das zweite Vorsprungselement und das erste Verbinderteil immer korrekt zueinander positioniert sind und nach Einführen der Kontaktelemente in die Aufnahmen des ersten Verbinderteils eine einfache Fixierung der Kontaktelemente möglich ist, ohne dass eine vorherige Justierung des zweiten Vorsprungselementes mit Bezug zu der seitlichen Öffnung der Aufnahmen des ersten Verbinderteils notwendig wäre.The second projection element, which is intended to engage in the lateral opening of the receptacles of the first connector part in order to hold the contact elements located in its receptacles, can for example be designed to be insertable into the lateral opening. However, it is particularly advantageous when the second projection element is provided so movably on the first connector part, that it is insertable into the lateral opening of the first connector part, but is fastened to the first connector part in a non-detachable manner. The non-detachable, but movable connection ensures that the second projection element and the first connector part are always positioned correctly to each other and after insertion of the contact elements in the receptacles of the first connector part a simple fixation of the contact elements is possible without a prior adjustment of the second Projecting element would be necessary with respect to the lateral opening of the receptacles of the first connector part.

Eine einfache Ausgestaltung sieht dazu einen mit dem ersten Verbinderteil verbundenen Klapphebel vor, an dem das zweite Vorsprungselement angeordnet ist. Zum Einführen der Kontaktelemente in die Aufnahme ist der Klapphebel zunächst geöffnet. Nach deren Einführen wird der Klapphebel angeklappt, so dass das zweite Vorsprungselement in die seitliche Öffnung des ersten Verbinderteils eingreift und die darin befindlichen Kontaktelemente fixiert. Eine einfache Lösung sieht vor, dass der Klapphebel mit Hilfe eines Filmscharniers an dem ersten Verbinderteil befestigt ist. Insbesondere, wenn das erste Verbinderteil oder beide Verbinderteile aus Kunststoff gefertigt sind, stellt dies eine kostengünstige Lösung dar.A simple embodiment provides for this purpose a folding lever connected to the first connector part, on which the second projection element is arranged. To insert the contact elements in the recording of the folding lever is initially open. After insertion thereof, the folding lever is folded so that the second projection element engages in the lateral opening of the first connector part and fixes the contact elements located therein. A simple solution provides that the folding lever is attached by means of a film hinge to the first connector part. In particular, if the first connector part or both connector parts are made of plastic, this represents a cost-effective solution.

Eine einfache Sicherungsmöglichkeit für das zweite Vorsprungselement in der seitlichen Öffnung der Aufnahmen des ersten Verbinderteils kann zum Beispiel durch einen Rastmechanismus gewährleistet werden, der einrastet, wenn das zweite Vorsprungselement in die seitliche Aufnahme des ersten Verbinderteils eingeführt wird.A simple securing possibility for the second projection element in the lateral opening of the receptacles of the first connector part can be ensured for example by a latching mechanism which engages when the second projection element is inserted into the lateral receptacle of the first connector part.

Das erste Vorsprungselement, das an dem ersten Verbinderteil vorgesehen ist und beim Zusammenstecken in die seitliche Öffnung der Aufnahmen des zweiten Verbinderteils eingreift, kann zum Beispiel ebenfalls an dem Klapphebel vorgesehen sein.The first projection element, which is provided on the first connector part and engages in mating in the lateral opening of the receptacles of the second connector part, may for example also be provided on the folding lever.

Die zwei Verbinderteile können zum Beispiel mit Schienen und entsprechenden Schienengegenstücken ausgestattet sein, die beim Zusammenstecken der beiden Verbinderteile als Führung dienen und sie nach dem Zusammensteckprozess fest aneinander halten. Eine einfache und sichere Ausgestaltung sieht vor, dass eines der Verbinderteile als Umgehäuse ausgestaltet ist, in das das andere Verbinderteil als Insert eingeschoben werden kann. Es entsteht so eine kompakte Einheit die nach außen weitgehend abgeschlossen ist. Vorzugsweise ist vorgesehen, dass das Umgehäuse durch das zweite Verbinderteil und das Insert durch das erste Verbinderteil gebildet werden.The two connector parts may for example be equipped with rails and corresponding rail counterparts, which serve as a guide during the mating of the two connector parts and hold them firmly together after the assembly process. A simple and secure embodiment provides that one of the connector parts is designed as a housing, in which the other connector part can be inserted as an insert. It creates a compact unit that is largely completed to the outside. It is preferably provided that the surrounding housing formed by the second connector part and the insert by the first connector part.

Bei einer solchen Ausführungsform werden zunächst die Kontaktelemente in die Aufnahmen des als Insert ausgestalteten ersten Verbinderteils eingeführt und mit dem an dem ersten Verbinderteil vorgesehenen zweiten Vorsprungselement in beschriebener Weise fixiert. Weitere Kontaktelemente werden in die Aufnahmen des als Umgehäuse ausgestalteten zweiten Verbinderteiles eingeführt. Einschieben des Inserts in das Umgehäuse bewirkt, dass das erste Vorsprungselement, das an dem Insert vorgesehen ist, in die seitliche Öffnung der Aufnahmen des Umgehäuses eingreift und die in dessen Aufnahmen eingeführten Kontaktelemente fixiert.In such an embodiment, the contact elements are first introduced into the receptacles of the first connector part designed as an insert and fixed in the manner described with the second projection element provided on the first connector part. Further contact elements are introduced into the receptacles of the second connector part designed as a surrounding housing. Insertion of the insert into the surrounding housing causes the first projection element, which is provided on the insert, to engage in the lateral opening of the receptacles of the surrounding housing and fixes the contact elements introduced in its receptacles.

In den Verbinderteilen können zum Beispiel metallische Kontakte integriert sein, die mit den eingeführten Kontaktelementen in elektrischen Kontakt kommen, um eine Kontaktierung zu ermöglichen. Bei einer bevorzugten Ausführungsform weisen die Verbinderteile jedoch erste Durchgangsöffnungen auf, durch die die elektrischen Kontaktelemente, die in die Aufnahmen eingesteckt werden, kontaktiert werden können.In the connector parts may be integrated, for example, metallic contacts that come into electrical contact with the inserted contact elements to allow a contact. In a preferred embodiment, however, the connector parts have first passage openings through which the electrical contact elements, which are inserted into the receptacles, can be contacted.

Bei einer Ausgestaltung, bei der eines der Verbinderteile als Umgehäuse und das zweite Verbinderteil als Insert vorgesehen sind, weist das Umgehäuse vorteilhafterweise zweite Durchgangsöffnungen auf, die mit den ersten Durchgangsöffnungen in den Aufnahmen des Inserts korrespondieren, um nach dem Einstecken des Inserts in das Umgehäuse eine Kontaktierung der Kontaktelemente in den Aufnahmen des Inserts zu ermöglichen.In one embodiment, in which one of the connector parts are provided as a surrounding housing and the second connector part as an insert, the surrounding housing advantageously has second passage openings which correspond to the first passage openings in the receptacles of the insert in order to insert the insert into the surrounding housing Contacting of the contact elements in the recordings of the insert to enable.

Das erste Vorsprungselement, das an dem ersten Verbinderteil vorgesehen ist und beim Zusammenstecken mit dem zweiten Verbinderteil in die seitliche Öffnung der Aufnahmen des zweiten Verbinderteils eingreift, kann zum Beispiel an der beim Zusammenstecken vorauslaufenden Seite des ersten Verbinderteils vorgesehen sein, wobei dann das erste und das zweite Verbinderteil derart ausgestaltet sind, dass das erste Verbinderteil in Richtung der Aufnahmen des zweiten Verbinderteils aufgesteckt wird. Eine sichere und einfache Ausgestaltung sieht vor, dass die Aufnahmen des zweiten Verbinderteils und die seitliche Öffnung in den Aufnahmen des zweiten Verbinderteils derart angeordnet sind, dass die als langgestreckte Öffnung ausgestaltete seitliche Öffnung in den Aufnahmen des zweiten Verbinderteils sich im Wesentlichen parallel zur Zusammensteckrichtung und im Wesentlichen senkrecht zur Einführrichtung der Kontaktelemente erstreckt. Beim Zusammenstecken kann dann ein entsprechend korrespondierend ausgestaltetes erstes Vorsprungselement, das an dem ersten Verbinderteil vorgesehen ist, von der seitlichen Öffnung in den Aufnahmen des zweiten Verbinderteils nach Art einer Schiene geführt werden, um so ein sicheres Zusammenstecken zu gewährleisten.The first projection element, which is provided on the first connector part and engages in mating with the second connector part in the lateral opening of the receptacles of the second connector part can for example, be provided on the side of the first connector part which precedes the mating, in which case the first and the second connector part are designed such that the first connector part is plugged in the direction of the receptacles of the second connector part. A secure and simple embodiment provides that the receptacles of the second connector part and the lateral opening in the receptacles of the second connector part are arranged such that the elongated opening designed as a lateral opening in the receptacles of the second connector part is substantially parallel to the mating direction and in Substantially extends perpendicular to the insertion direction of the contact elements. During mating, a correspondingly designed first projection element, which is provided on the first connector part, can then be guided by the lateral opening in the receptacles of the second connector part in the manner of a rail in order to ensure a secure mating.

Weisen das erste und/oder das zweite Verbinderteil mehr als eine Aufnahme auf, ist es vorteilhaft, wenn die Aufnahmen eines Verbinderteils über eine gemeinsame seitliche Öffnung für alle Aufnahmen dieses Verbinderteils verfügen.If the first and / or the second connector part have more than one receptacle, it is advantageous if the receptacles of a connector part have a common lateral opening for all receptacles of this connector part.

Ein erfindungsgemäßes elektrisches Verbindungssystem weist einen erfindungsgemäßen elektrischen Verbinder und einer der Gesamtzahl der Aufnahmen in dem ersten und dem zweiten Verbinderteil entsprechende Anzahl in die Aufnahmen einsteckbarer Kontaktelemente auf. Die Vorteile eines solchen erfindungsgemäßen elektrischen Verbindungssystems und vorteilhafter Ausgestaltungen davon ergeben sich aus den oben bereits mit Bezug zu dem erfindungsgemäßen elektrischen Verbinder geschilderten Vorteilen und seiner Ausgestaltungen.An inventive electrical connection system has an electrical connector according to the invention and a number of the receptacles in the first and the second connector part corresponding number in the receptacles plug-in contact elements. The advantages of such an electrical connection system according to the invention and advantageous embodiments thereof are evident from the advantages already described above with reference to the electrical connector according to the invention and its embodiments.

Ein erfindungsgemäßes elektrisches Verbindungssystem kann über elektrische Kontaktelemente verfügen, die in den Aufnahmen durch ein in die seitlichen Aufnahmen eingreifenden Vorsprungselementes festgeklemmt werden. Bei einer bevorzugten Ausgestaltung weisen die Kontaktelemente seitliche Ausnehmungen auf, die bei korrekter Ausrichtung der Kontaktelemente in den Aufnahmen mit den seitlichen Öffnungen der Aufnahmen korrespondieren, um einen Eingriff der Vorsprungselemente in die Ausnehmungen zu ermöglichen und so die Kontaktelemente zu sichern.An electrical connection system according to the invention may have electrical contact elements which are clamped in the receptacles by a projection element engaging in the lateral receptacles. In a preferred embodiment, the contact elements on lateral recesses, which correspond with the correct orientation of the contact elements in the receptacles with the lateral openings of the receptacles to allow engagement of the protrusion elements in the recesses and thus secure the contact elements.

Dadurch entsteht der zusätzliche Vorteil, dass es nur bei korrekter Lage der Kontaktelemente möglich ist, die beiden Verbinderteile vollständig zusammenzustecken. Sind die beiden Verbinderteile also vollständig zusammengesteckt, ist auf diese Weise auch leicht von außen erkennbar, dass die Kontaktelemente korrekt fixiert sind.This results in the additional advantage that it is possible only with the correct position of the contact elements to completely assemble the two connector parts. Thus, if the two connector parts are completely plugged together, it is easy to see from the outside that the contact elements are correctly fixed in this way.

Die Erfindung betrifft weiterhin ein Verfahren zur Bildung eines erfindungsgemäßen elektrischen Verbindungssystems. In die Aufnahmen des ersten und des zweiten Verbinderteils werden elektrische Kontaktelemente eingesteckt. Entweder bevor oder nachdem die Kontaktelemente in die Aufnahmen des zweiten Verbinderteils eingesteckt werden, wird das an dem ersten Verbinderteil vorgesehene zweite Vorsprungselement mit der seitlichen Öffnung der Aufnahmen des ersten Verbinderteils in Eingriff gebracht um die in dessen Aufnahmen eingesteckten Kontaktelemente zu fixieren. Ist zum Beispiel gemäß einer besonderen Ausführungsform das zweite Vorsprungselement an dem ersten Verbinderteil mit Hilfe eines Klapphebels befestigt, so wird der Klapphebel angeklappt, so dass das zweite Vorsprungselement in die seitliche Öffnung der Aufnahmen des ersten Verbinderteils eingreift. Auf diese Weise sind die Kontaktelemente in den Aufnahmen des ersten Verbinderteils fest fixiert. Das erste Verbinderteil wird dann mit dem zweiten Verbinderteil zusammengesteckt, so dass das ebenfalls an dem ersten Verbinderteil vorgesehene erste Vorsprungselement in die seitliche Öffnung der Aufnahmen des zweiten Verbinderteils eingreift. Auf diese Weise werden die Kontaktelemente in den Aufnahmen des zweiten Verbinderteils ebenfalls fixiert. Während des Zusammensteckprozesses sind die Kontaktelemente in den Aufnahmen des ersten Verbinderteils bereits fest fixiert, so dass sie beim Zusammensteckprozess nicht mehr herausrutschen oder deplatziert werden können.The invention further relates to a method for forming an electrical connection system according to the invention. In the receptacles of the first and the second connector part electrical contact elements are inserted. Either before or after the contact elements are inserted into the receptacles of the second connector part, the second projection element provided on the first connector part is brought into engagement with the lateral opening of the receptacles of the first connector part in order to fix the contact elements inserted in its receptacles. If, for example, according to a particular embodiment, the second projection element is fastened to the first connector part by means of a folding lever, then the folding lever is folded so that the second projection element engages in the lateral opening of the receptacles of the first connector part. In this way, the contact elements are firmly fixed in the receptacles of the first connector part. The first connector part is then plugged together with the second connector part, so that the first protrusion element likewise provided on the first connector part engages in the lateral opening of the receptacles of the second connector part. In this way, the contact elements in the receptacles of the second connector part are also fixed. During the assembly process, the contact elements are already firmly fixed in the receptacles of the first connector part, so that they can no longer slip out or be misplaced during the assembly process.

The size of the contact element depends on the size of the respective receptacle of the connector part into which it is to be inserted.

In Fig. 1 ist ein erfindungsgemäßer elektrischer Verbinder 10 in seiner Gesamtheit gezeigt. 12 bezeichnet das erste Verbinderteil, das mit Bezug zu Fig. 2 und 4 näher erläutert werden wird. Es umfasst Aufnahmen 16, in die Kontaktelemente 46 eingeführt werden können. Das erste Verbinderteil ist hier als Insert 12 ausgestaltet, das in das als Umgehäuse 14 ausgestaltete zweite Verbinderteil eingeschoben werden kann, wodurch der Zustand entsteht, der in Fig. 1 gezeigt ist. Der Einsteckprozess wird von dem Einschubelement 36 und der korrespondierenden Führungsschiene 34 geführt.In Fig. 1 For example, an electrical connector 10 according to the invention is shown in its entirety. 12 denotes the first connector part, which with reference to Fig. 2 and 4 will be explained in more detail. It comprises receptacles 16 into which contact elements 46 can be inserted. The first connector part is configured here as an insert 12, which can be inserted into the second connector part designed as a surrounding housing 14, whereby the state arises that in Fig. 1 is shown. The insertion process is guided by the insertion element 36 and the corresponding guide rail 34.

Das Umgehäuse 14 umfasst Aufnahmen 18, in die ebenfalls Kontaktelemente 46 eingesteckt werden können. Bei der gezeigten Ausführungsform sind die Aufnahmen 16 des ersten Verbinders des Inserts 12 und die Aufnahmen 18 des Umgehäuses 14 unterschiedlich groß, um unterschiedliche große Kontaktelemente 46 aufnehmen zu können.The surrounding housing 14 comprises receptacles 18 into which contact elements 46 can likewise be inserted. In the embodiment shown, the receptacles 16 of the first connector of the insert 12 and the receptacles 18 of the surrounding housing 14 are of different sizes in order to accommodate different large contact elements 46.

Die Querschnittsform der Kontaktelemente kann zum Beispiel auch an die innere Form der Aufnahme 16, 18 angepasst sein.The cross-sectional shape of the contact elements may for example also be adapted to the inner shape of the receptacle 16, 18.

Selbstverständlich sind auch Ausführungsformen möglich, bei denen die Aufnahmen der beiden Verbinderteile 12, 14 gleich groß sind und/oder in anderer Anzahl vorhanden sind, als es in Fig. 1 gezeigt ist.Of course, embodiments are possible in which the receptacles of the two connector parts 12, 14 are the same size and / or are present in a different number than it is in Fig. 1 is shown.

Das als Insert 12 ausgestaltete erste Verbinderteil weist einen Klapphebel 24 mit einem ersten Vorsprungselement 20 und einem zweiten Vorsprungselement 22 auf. In dem in Fig. 1 gezeigten zusammengesteckten Zustand greift das erste Vorsprungselement 20 in die seitliche Öffnung 26 in den Aufnahmen 18 des Umgehäuses 14 ein.

In Fig. 2 ist der geöffnete Zustand gezeigt, wobei die Zentrieröffnung 40 in dem Klapphebel 24 erkennbar ist, die beim Anklappen des Klapphebels 24 in Pfeilrichtung 25 mit dem Zentrierelement 42 zur Führung des Klapphebels 24 zusammenwirkt. Die seitliche Öffnung 28 ragt bis in die Aufnahmen 16 des Inserts 12, so dass diese im Bereich der seitlichen Öffnung 28 offen sind. Fig. 2 shows the insert 12 in detail. The folding lever 24 is attached via a film hinge 38 to the insert 12. In Fig. 2 the opened state is shown, wherein the centering opening 40 can be seen in the folding lever 24, which cooperates when folding lever 24 in the direction of arrow 25 with the centering element 42 for guiding the folding lever 24. The lateral opening 28 protrudes into the receptacles 16 of the insert 12, so that they are open in the region of the lateral opening 28.

Rastelemente 30 und 32 verfügen über korrespondierende angeschrägte Kanten, die beim Zusammenklappen aneinander abgleiten, bis das Rastelement 32 hinter dem Rastelement 30 zu liegen kommt und den Klapphebel 24 festlegt.Locking elements 30 and 32 have corresponding bevelled edges which slide together when folding until the locking element 32 comes to rest behind the locking element 30 and determines the folding lever 24.

Der Pfeil 52 zeigt die Richtung, in der Kontaktelemente 46 in die Aufnahmen 16 des Inserts 12 eingeführt werden können.The arrow 52 shows the direction in which contact elements 46 can be inserted into the receptacles 16 of the insert 12.

Fig. 3 zeigt das Umgehäuse 14 im Detail. Hier ist insbesondere erkennbar, dass die seitliche Öffnung 26 langgestreckt ist und sich senkrecht zu den Aufnahmen 18 erstreckt. Sie ragt bis in die Aufnahmen 18, so dass diese im Bereich der seitlichen Öffnung 26 offen sind. Fig. 3 shows the enclosure 14 in detail. Here it can be seen in particular that the lateral opening 26 is elongate and extends perpendicular to the receptacles 18. It protrudes into the receptacles 18, so that they are open in the region of the lateral opening 26.

Der Pfeil 54 deutet die Einführrichtung an, in der Kontaktelemente 46 in die Aufnahmen 18 eingeführt werden können.The arrow 54 indicates the insertion direction in which contact elements 46 can be inserted into the receptacles 18.

Im unteren Bereich des Umgehäuses 14 sind Durchgangsöffnungen 44 vorgesehen, die mit den unteren Öffnungen in den Aufnahmen 16 des Inserts 12 derart korrespondieren, dass bei eingestecktem Insert 12 eine Kontaktierung der in den Aufnahmen 16 des Inserts 12 eingeführten Kontaktelemente möglich ist.Through openings 44 are provided in the lower region of the surrounding housing 14, which correspond to the lower openings in the receptacles 16 of the insert 12 in such a way that, when the insert 12 is plugged in, a contacting of the contact elements introduced into the receptacles 16 of the insert 12 is possible.

Der Pfeil 50 deutet die Einsteckrichtung an, in der das Insert 12 in das Umgehäuse 14 eingesteckt werden kann.The arrow 50 indicates the plug-in direction in which the insert 12 can be inserted into the surrounding housing 14.

Fig. 4 zeigt eine weitere Ansicht des Inserts 12, wobei hier der Klapphebel 24 angeklappt ist und die Rastelemente 30, 32 verrastet sind. Fig. 4 shows a further view of the insert 12, in which case the folding lever 24 is folded and the locking elements 30, 32 are latched.

Die gezeigte Ausführungsform des elektrischen Verbindungssystems wird wie folgt eingesetzt:The illustrated embodiment of the electrical connection system is used as follows:

Zum Beispiel die Drahtenden eines Kabelbaums werden mit Kontaktelementen 46 versehen, zum Beispiel in an sich bekannter Weise darin eingeklemmt oder verlötet.For example, the wire ends of a wire harness are provided with contact elements 46, for example clamped or soldered therein in a manner known per se.

Kleinere Kontaktelemente 46 werden in Pfeilrichtung 52 in das Insert 12 eingesteckt. Dabei befindet sich der Klapphebel 24 in der Position der Fig. 2, so dass die Kontaktelemente 46 ungehindert in die Aufnahmen eintreten können. Sie werden derart ausgerichtet, dass ihre seitlichen Aufnahmen 48 mit der seitlichen Öffnung 28 korrespondieren. Dann wird der Klapphebel 24 in Pfeilrichtung 25 an das Insert 12 angeklappt, wobei er von den korrespondierenden Führungselementen 40, 42 geführt wird. Das zweite Vorsprungselement 22 tritt in die seitliche Öffnung 28 in den Aufnahmen 16 des Inserts 12 und somit in die seitliche Ausnehmung 48 der in den Aufnahmen 16 eingeführten Kontaktelemente 46 ein. Rastelemente 30, 32 verrasten miteinander und fixieren den Klapphebel 24 in einer Position, wie sie in Fig. 4 erkennbar ist. Der Übersichtlichkeit halber sind in Fig. 4 die in die Aufnahmen 16 eingeführten Kontaktelemente 46 nicht gezeigt.Smaller contact elements 46 are inserted in the direction of arrow 52 in the insert 12. In this case, the folding lever 24 is in the position of Fig. 2 so that the contact elements 46 can enter the receptacles unhindered. They are aligned such that their lateral receptacles 48 correspond to the lateral opening 28. Then, the folding lever 24 is folded in the direction of arrow 25 to the insert 12, wherein it is guided by the corresponding guide elements 40, 42. The second projection element 22 enters into the lateral opening 28 in the receptacles 16 of the insert 12 and thus into the lateral recess 48 of the contact elements 46 inserted in the receptacles 16. Locking elements 30, 32 engage with each other and fix the folding lever 24 in a position as in Fig. 4 is recognizable. For the sake of clarity, in Fig. 4 the introduced into the receptacles 16 contact elements 46 is not shown.

Das Vorsprungselement 22 greift in die seitlichen Aufnehmungen 48 der Kontaktelemente 46 ein und fixiert diese in den Aufnahmen 16.The projection element 22 engages in the lateral recesses 48 of the contact elements 46 and fixes them in the receptacles 16.

Die so gebildete Einheit wird in Richtung des Pfeils 50 in das Umgehäuse 14 eingeschoben.The unit thus formed is inserted in the direction of the arrow 50 in the surrounding housing 14.

In die Aufnahmen 18 des Umgehäuses 14 werden in Pfeilrichtung 54 (Fig. 3) Kontaktelemente 46 eingeschoben. Entsprechend der größeren Aufnahmen 18 können diese Kontaktelemente 46 ebenfalls größer ausgestaltet sein. Die in die Aufnahmen 18 eingeführten Kontaktelemente werden so ausgerichtet, dass ihre seitlichen Ausnehmungen 48 mit der seitlichen Öffnung 26 korrespondieren.In the receptacles 18 of the Umgehäuses 14 are in the direction of arrow 54 ( Fig. 3 ) Contact elements 46 inserted. Corresponding to the larger receptacles 18, these contact elements 46 can also be made larger. The introduced into the receptacles 18 contact elements are aligned so that their lateral recesses 48 correspond to the lateral opening 26.

Die Einheit aus Insert 12 und den in die Aufnahmen 16 des Inserts 12 eingeführten Kontaktelemente wird in Pfeilrichtung 50 in das Umgehäuse 14 eingesteckt. Dabei gelangt das erste Vorsprungselement 20 des Inserts 12 mit der seitlichen Öffnung 26 der Aufnahmen 18 des Umgehäuses 14 in Eingriff. Es tritt dabei in die seitlichen Ausnehmungen 48 der Kontaktelemente in den Aufnahmen 18 ein und hält diese in den Aufnahmen 18 fest. Die Einsteckbewegung 50 wird zum einen durch das Zusammenwirken des ersten Vorsprungselementes 20 und der langgestreckten seitlichen Öffnung 26 in den Aufnahmen 18 und zum anderen durch das Zusammenwirken der korrespondierenden Führungselemente 34, 36 geführt. Bei vollständig eingeschobenem Insert 12 sind die Durchgangsöffnungen 44 im Bodenbereich des Umgehäuses 14 korrespondierend zu den Aufnahmen 16 im Insert 12 angeordnet. Die Aufnahmen 16 umfassen wie erläutert in den Figuren nicht sichtbare Öffnungen im unteren Bereich des Inserts 12, so dass durch die nicht sichtbaren Öffnungen und die Durchgangsöffnungen 44 eine Kontaktierung der in die Aufnahmen 16 eingeführten Kontaktelemente möglich ist.The unit of insert 12 and the inserted into the receptacles 16 of the insert 12 contact elements is inserted in the direction of arrow 50 in the surrounding housing 14. In this case, the first projection element 20 of the insert 12 with the lateral opening 26 of the receptacles 18 of the Umgehäuses 14 engages. It occurs in the lateral recesses 48 of the contact elements in the receptacles 18 and holds them in the receptacles 18 firmly. The insertion movement 50 is guided on the one hand by the interaction of the first projection element 20 and the elongated lateral opening 26 in the receptacles 18 and on the other hand by the interaction of the corresponding guide elements 34, 36. When fully inserted insert 12, the through holes 44 are arranged in the bottom region of the surrounding housing 14 corresponding to the receptacles 16 in the insert 12. The receptacles 16 include, as explained in the figures, not visible openings in the lower region of the insert 12, so that a contacting of the introduced into the receptacles 16 contact elements is possible through the non-visible openings and the through holes 44.

Es entsteht ein elektrisches Verbindungssystem 10 mit Kontaktelementen 46, die fest in den Aufnahmen 16, 18 fixiert sind. Die Verbindergesamtheit 10 kann jetzt verwendet werden, um die einzelnen Kontaktelemente in den Aufnahmen 16, 18 in gewünschter Weise weiter zu kontaktieren bzw. zum Beispiel das elektrische Verbindungssystem 10 nach Art eines Steckers auf ein entsprechendes Steckergegenstück, zum Beispiel eine Geräteaufnahme, aufzustecken.The result is an electrical connection system 10 with contact elements 46 which are fixed in the receptacles 16, 18. The connector aggregate 10 can now be used to contact the individual contact elements in the receptacles 16, 18 in the desired manner or, for example, the electrical connection system 10 in the manner of a plug on a corresponding connector counterpart, for example, a device receptacle aufzustecken.
