Description

Stand der TechnikState of the art

Steckverbindungen mit einer Primärverriegelung und einem Verriegelungskamm, der auch Sekundärverriegelung genannt wird und eine Zusatzverriegelung für die elektrischen Kontaktelemente zur Erhöhung der Zuverlässigkeit der Steckverbindungen bildet, werden insbesondere dort eingesetzt, wo die Steckverbindungen Erschütterungen und Vibrationen ausgesetzt sind, die die Zuverlässigkeit der elektrischen Verbindung gefährden können. Üblicherweise sind die Steckverbindungen aus einem aus elektrisch nicht leitfähigem Material bestehenden Kontaktträger und einem mit diesem zusammensteckbaren Gegenkontaktträger gebildet, wobei in ihnen Kontaktelementaufnahmekammern zur Aufnahme von elektrischen Kontaktelementen und/oder elektrischen Gegenkontaktelementen ausgebildet sind. Die elektrischen Kontaktelemente können dabei Verriegelungszungen oder Rastlanzen zum Zusammenwirken mit in den Kontaktelementaufnahmekammerwänden ausgebildeten Aussparungen oder Schultern und dem Verriegelungskamm aufweisen. Durch die beim Einführen der elektrischen Kontaktelemente in die Kontaktelementaufnahmekammern erfolgt eine Primärverriegelung und damit eine Fixierung der einzelnen Kontaktelemente im Kontaktträger. Nach erfolgter Primärverriegelung der elektrischen Kontaktelemente kann der Verriegelungskamm am Kontaktträger von einer Nichtgebrauchsstellung in eine Verriegelungsstellung quer zur Steckrichtung des Kontaktträgers verlagert werden, wobei der Verriegelungskamm in der Verriegelungsstellung mit dem Kontaktträger verrastet ist und mit sämtlichen elektrischen Kontaktelementen in Formschluss tritt. Ein Verlagern des Verriegelungskammes in die Verriegelungsstellung ist erst dann möglich, wenn sämtliche Kontaktelemente korrekt in den Kontaktelementaufnahmekammern angeordnet und primärverriegelt sind. Ein derartiger Verriegelungskamm ist beispielsweise aus der DE 41 02 535 C1 bekannt.Plug-in connections with a primary lock and a locking comb, which is also called a secondary lock and forms an additional lock for the electrical contact elements to increase the reliability of the plug-in connections, are used in particular where the plug-in connections are exposed to shocks and vibrations that can jeopardize the reliability of the electrical connection , Usually, the plug-in connections are formed from a contact carrier consisting of electrically nonconductive material and a mating contact carrier which can be plugged together with contact element receiving chambers for receiving electrical contact elements and / or electrical mating contact elements. The electrical contact elements can have locking tongues or locking lances for interacting with recesses or shoulders formed in the contact element receiving chamber walls and the locking comb. By the insertion of the electrical contact elements in the contact element receiving chambers there is a primary locking and thus a fixation of the individual contact elements in the contact carrier. After the primary locking of the electrical contact elements, the locking comb on the contact carrier can be displaced from a non-use position into a locking position transversely to the insertion direction of the contact carrier, wherein the locking comb is locked in the locking position with the contact carrier and enters into positive engagement with all electrical contact elements. A displacement of the locking comb in the locking position is only possible if all contact elements are properly located in the contact element receiving chambers and are primarily locked. Such a locking comb is for example from the DE 41 02 535 C1 known.

Bei hochpoligen Steckverbindern ist es zwischenzeitlich auch üblich, zwei oder mehr Kontaktträger in einem gemeinsamen Gehäuse zusammenzufassen. Hierbei ist es beispielsweise möglich, mehrere aus spritzfähigem Kunststoff gefertigte zweireihige Kontaktträger in ein gemeinschaftliches Gehäuse einzusetzen, wobei diese Kontaktträger zur Herstellung von Hinterschnitten Schieber in der korrespondierenden Spritzgussform benötigen, wobei die Schieber in die Längsseiten der Kontaktträger greifen. Die Kontaktträger werden in der Regel mit dem gemeinsamen Gehäuse durch ein Zusammenwirken von an dem Gehäuse und an den Kontaktträgern angeordneten Vorsprüngen und/oder Rücksprüngen verrastet. Ein derartiger Steckverbinder bietet den Vorteil, dass seitens des Herstellers auch identische Kontaktträger an einem gemeinsamen Gehäuse angeordnet werden können. Die elektrischen Steckverbinder werden aus Platzmangel an den Einbaustellen in immer kleinerem Querschnitt in der Regel aus Kunststoff gefertigt. Damit die Funktionstüchtigkeit aufrechterhalten werden kann, müssen die einzelnen Komponenten entsprechend klein und fein ausgeformt sein. Oft ist es dabei schwierig, die nötige Stabilität für montagebedingte Belastungen zu schaffen. So ist es insbesondere erwünscht, dass die Kontaktträger ohne großen Kraftaufwand oder zusätzliche Teile mit dem Gehäuse verrastet werden können. Um jedoch eine gute elektrische Verbindung zwischen den elektrischen Kontaktelementen und den elektrischen Gegenkontaktelementen sicherzustellen, sind hierfür vorbestimmte Haltekräfte erforderlich, die nicht unterschritten werden dürfen. Insbesondere beim Trennen derartiger Steckverbindungen lässt sich jedoch aufgrund der zur Überwindung der Haltekräfte erforderlichen Auszugskräfte zum Trennen der elektrischen Kontaktelemente von den elektrischen Gegenkontaktelementen nicht zuverlässig vermeiden, dass ein Kontaktträger sich aus dem gemeinsamen Gehäuse löst.In the case of high-pole connectors, it is also customary in the meantime to combine two or more contact carriers in a common housing. In this case, it is possible, for example, to use a plurality of injection-molded plastic double-row contact carrier in a common housing, said contact carrier for the production of undercuts slide in the corresponding injection mold, the slides engage in the longitudinal sides of the contact carrier. The contact carriers are usually locked to the common housing by an interaction of arranged on the housing and on the contact carriers projections and / or recesses. Such a connector has the advantage that the manufacturer and identical contact carrier can be arranged on a common housing. The electrical connectors are made due to lack of space at the installation sites in ever smaller cross-section usually made of plastic. In order for the functionality to be maintained, the individual components must be correspondingly small and finely formed. Often it is difficult to create the necessary stability for assembly-related loads. So it is particularly desirable that the contact carrier can be locked without much effort or additional parts with the housing. However, to ensure a good electrical connection between the electrical contact elements and the electrical mating contact elements, this predetermined holding forces are required, which must not be exceeded. In particular, when disconnecting such connectors can be due to the extraction forces required to overcome the holding forces for separating the electrical contact elements of the electrical mating contact elements not reliably avoid that a contact carrier dissolves from the common housing.

Zusammenfassung der ErfindungSummary of the invention

Der Verriegelungskamm weist einen Verriegelungskammrücken auf. An dem Verriegelungskammrücken ist wenigstens eine Zinke fest verbunden. Die wenigstens eine Zinke ist in einen Einführschlitz des Kontaktträgers einführbar. Der Verriegelungskamm weist ein Stützelement auf, wobei durch das Stützelement ein Lösen des mit einem Gehäuse verrasteten Kontaktträgers verhindert ist, wenn der Verriegelungskamm in den Kontaktträger eingeführt und in eine Verriegelungsstellung verlagert ist.According to a first embodiment of the invention, a locking comb made of electrically non-conductive material for locking electrical contact elements in contact element receiving chambers of a contact carrier is provided.

Natürlich können das Gehäuse, der wenigstens eine Kontaktträger und der Verriegelungskamm derart ausgeführt sein, dass eine Verriegelung des Verriegelungskammes an dem Kontaktträger erfolgt. Wenn an dem Verriegelungskammrücken mehr Zinken als der eine Zinke angeordnet sind, so erstrecken sich diese Zinken in der Regel parallel zueinander. Auch sind die Zinken in der Regel derart angeordnet, dass sie gemeinsam eine gemeinsame Ebene aufspannen. Insbesondere, wenn die Verrastung des Kontaktträgers mit dem Gehäuse durch ein Zusammenwirken von sowohl an dem Kontaktträger als auch an einer Gehäusewandung angeordneten Rastelementen in Form von miteinander korrespondierenden Vorsprüngen und/oder Rücksprüngen stattfindet, ist es erwünscht, dass die Gehäusewandung, an der die entsprechenden Rastelemente angeordnet sind, dünn und damit labil ausgebildet ist. Hierdurch wird bei der Montage des Kontaktträgers an das Gehäuse bewirkt, dass die Gehäusewandung, solange der Kontaktträger noch nicht seine verrastende Position erreicht hat, gegenüber dem Kontaktträger zurücktritt oder ausweicht. Hierdurch wird einerseits erreicht, dass der Kontaktträger mit geringem Kraftaufwand an das Gehäuse in seine verrastete Position verlagert werden kann. Andererseits wird durch das Ausweichen der Gehäusewandung erreicht, dass die Rastelemente durch das Verlagern des Kontaktträgers in die verrastende Position nicht beschädigt werden. Allerdings hat sich gezeigt, dass bei einer Belastung des wenigstens einen in dem Gehäuse angeordneten Kontaktträgers in einer Auszugsrichtung, wobei die Belastung beispielsweise bei einem Trennen der elektrischen Steckverbindung zur Überwindung der Haltekräfte der elektrischen Kontaktelemente an den elektrischen Gegenkontaktelementen auftreten kann und die einer Montagerichtung des Kontaktträgers in das Gehäuse entgegengesetzt ist, diese mit den Rastelementen versehenen Gehäusewandungen ebenfalls ausweichen können. Durch das Stützelement kann die Gehäusewandung beispielsweise an einer Innenseite unterstützt werden, wobei die Innenseite einer mit den Rastelementen versehenen Außenseite gegenüberliegt. Somit kann der Kontaktträger an das Gehäuse mit geringem Kraftaufwand an seine verrastende Position verlagert werden. Anschließend wird der Verriegelungskamm in die Einführschlitze des Kontaktträgers geführt, wobei hierdurch die primärverriegelten Kontaktelemente sekundär verriegelt werden können und gleichzeitig mittels des Stützelements die mit den Rastelementen versehene Gehäusewandung gestützt werden kann. Durch diese Stützung wird ein Ausweichen der Gehäusewandung durch ein Aufbringen der Kraft in Auszugsrichtung zumindest weitestgehend verhindert. Dadurch kann ein Lösen des Kontaktträgers aus dem Gehäuse beim Trennen der Steckverbindung zuverlässig vermieden werden. Das Stützelement kann hierbei an dem Verriegelungskamm an wenigstens einem der Zinken und/oder an dem Verriegelungskammrücken angeordnet sein. Natürlich kann das Stützelement an jedem Zinken des Verriegelungskammes angeordnet sein, durch welchen die mit Rastelementen versehene Gehäusewandung gestützt werden soll.In the locking position, all in the Kontaktelelemtaufnahmekammern the contact carrier primary locked electrical contact elements can be positively connected to the locking comb. As a rule, the locking comb is locked in the locking position on the housing. This locking can be done positively. Of course, the housing, the at least one contact carrier and the locking comb can be designed such that a locking of the locking comb takes place on the contact carrier. If more prongs than the one prong are arranged on the locking comb back, these prongs generally extend parallel to one another. Also, the tines are usually arranged such that they jointly span a common plane. In particular, when the latching of the contact carrier with the housing takes place by an interaction of both arranged on the contact carrier and on a housing wall locking elements in the form of mutually corresponding projections and / or recesses, it is desirable that the housing, where the corresponding locking elements are arranged, thin and thus labile is. As a result, during assembly of the contact carrier to the housing causes the housing wall, as long as the contact carrier has not yet reached its latching position, recedes or escapes from the contact carrier. As a result, on the one hand achieved that the contact carrier can be moved with little effort to the housing in its locked position. On the other hand, it is achieved by avoiding the housing wall that the locking elements are not damaged by the displacement of the contact carrier in the latching position. However, it has been shown that when the at least one contact carrier arranged in the housing is loaded in a pull-out direction, the load can occur, for example, when disconnecting the electrical plug connection to overcome the holding forces of the electrical contact elements on the electrical mating contact elements and that of a mounting direction of the contact carrier is opposite in the housing, these can also dodge provided with the locking elements housing walls. By the support member, the housing wall can be supported for example on an inner side, wherein the inside of a provided with the locking elements outside. Thus, the contact carrier can be moved to the housing with little effort to its latching position. Subsequently, the locking comb is guided in the insertion slots of the contact carrier, thereby the primary locked contact elements can be locked secondarily and at the same time by means of the support member provided with the locking elements housing wall can be supported. By this support, a deflection of the housing wall by applying the force in the extension direction is at least largely prevented. Thereby, a release of the contact carrier from the housing when disconnecting the connector can be reliably avoided. The support element may in this case be arranged on the locking comb on at least one of the prongs and / or on the locking comb back. Of course, the support element may be arranged on each tine of the locking comb, through which the housing wall provided with locking elements is to be supported.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist das Stützelement an der wenigstens einen Zinke angeordnet.According to a further embodiment of the invention, the support element is arranged on the at least one prong.

Hierdurch wird bewirkt, dass beim Einführen des Verriegelungskammes in die Einführschlitze des Kontaktträgers gleichzeitig die mit den Rastelementen versehene Gehäusewandung gestützt wird. Die Stützung kann hierbei sukzessive je nach Fortschritt des Einführens des wenigstens einen Zinken in den Einführschlitz des Kontaktträgers erfolgen. Der Kontaktträger kann mit dem Gehäuse bereits verrastet sein und die elektrischen Kontaktelemente an dem Kontaktträger primär verriegelt sein, bevor der wenigstens eine Zinke in den Einführschlitz geführt wird. Auch muss das Stützelement nicht so lange wie der Zinken ausgeführt sein. Vielmehr kann das Stützelement enden, wenn in der Verschieberichtung des Verriegelungskammes, die sich in der Regel quer zu der Auszugsrichtung des Gehäuses, respektive des an dem Gehäuse angeordneten Kontaktträgers, aus dem Gegenkontaktträger erstreckt, wenn das in Verschieberichtung gesehen letzte Rastelement gestützt ist. Natürlich kann das Stützelement an jedem Zinken oder auch nur einem Teil der Zinken angeordnet sein.This has the effect that, when the locking comb is inserted into the insertion slots of the contact carrier, the housing wall provided with the latching elements is simultaneously supported. The support can be carried out successively depending on the progress of the insertion of the at least one prong in the insertion slot of the contact carrier. The contact carrier may already be latched to the housing and the electrical contact elements may be primarily locked to the contact carrier before the at least one prong is guided into the insertion slot. Also, the support element does not have to be designed as long as the tines. Rather, the support member may end when extending in the direction of the locking comb, which is generally transverse to the extension direction of the housing, respectively arranged on the housing contact carrier from the mating contact carrier, when seen in the displacement direction last locking element is supported. Of course, the support member may be disposed on each tine or even a portion of the tines.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist das Stützelement des Verriegelungskamms unlösbar an der wenigstens einen Zinke verbunden.According to a further embodiment of the invention, the support element of the locking comb is permanently connected to the at least one prong.

Hierbei muss das Stützelement nicht zwangsweise aus demselben Material wie der Verriegelungskamm bestehen. Beispielsweise kann der wenigstens eine Zinke aus elektrisch nicht leitendem Kunststoff hergestellt sein, während das Stützelement beispielsweise aus Metall hergestellt sein kann.In this case, the support element does not necessarily consist of the same material as the locking comb. For example, the at least one prong may be made of electrically non-conductive plastic, while the support member may be made of metal, for example.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung erstreckt sich das Stützelement des Verriegelungskammes in Erstreckungsrichtung der Zinke.According to a further embodiment of the invention, the support element of the locking comb extends in the extension direction of the prong.

Das Stützelement kann in Aufsicht auf die Zinke beispielsweise gerade verlaufen oder auch wellenförmig. Weiterhin kann das Stützelement beispielsweise als ein Steg ausgebildet sein, der sich aus einer durch zwei benachbarte Zinken aufgespannten Ebene in Richtung der Rastelemente erstreckt. Auch kann das Stützelement so ausgebildet sein, dass es mit den an der Gehäusewandung angeordneten Rastelementen überlappt. Durch eine Überlappung mit den Rastelementen kann die Gehäusewandung möglicherweise nochmals filigraner gestaltet werden, wobei das Lösen des mit dem Gehäuse verrasteten Kontaktträgers zuverlässig verhindert werden kann.The support element may, for example, run straight in a plan view of the prong or else wavy. Furthermore, the support member may be formed, for example, as a web which extends from a plane spanned by two adjacent tines in the direction of the locking elements. Also, the support member may be formed so that it overlaps with the arranged on the housing wall locking elements. By overlapping with the latching elements, the housing wall can possibly be made even filigree, the release of the latched to the housing contact carrier can be reliably prevented.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist der Verriegelungskamm einstückig ausgebildet.According to a further embodiment of the invention, the locking comb is integrally formed.

Beispielsweise kann hierdurch der Verriegelungskamm komplett in einem Herstellungsvorgang als Spritzgussteil aus nicht leitfähigem Kunststoff hergestellt werden. Hierdurch lässt sich der Verriegelungskamm sehr preisgünstig herstellen.For example, in this way, the locking comb can be completely manufactured in a manufacturing process as an injection molded part made of non-conductive plastic. As a result, the locking comb can be produced very inexpensively.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung sind an dem Verriegelungskammrücken des Verriegelungskamms eine erste, eine zweite und eine dritte Zinke fest verbunden, wobei die erste, die zweite und die dritte Zinke sich parallel zueinander erstrecken. Die zweite Zinke ist zwischen der ersten und der dritten Zinke angeordnet. Die erste und die zweite Zinke sind in Einführschlitze eines ersten Kontaktträgers und die zweite und die dritte Zinke in Einführschlitze eines zu dem ersten Kontaktträger benachbarten zweiten Kontaktträgers einführbar. Die zweite Zinke weist das Stützelement auf, wobei durch das Stützelement ein Lösen des mit dem Gehäuse verrasteten ersten und zweiten Kontaktträgers verhindert ist, wenn der Verriegelungskamm in den Kontaktträger eingeführt und in eine Verriegelungsstellung verlagert ist.According to a further embodiment of the invention, a first, a second and a third prong are fixedly connected to the locking crest of the locking comb, wherein the first, the second and the third prong extend parallel to each other. The second prong is arranged between the first and the third prong. The first and second prongs are insertable into insertion slots of a first contact carrier and the second and third prongs are inserted into insertion slots of a second contact carrier adjacent to the first contact carrier. The second prong has the support element, wherein a release of the latched with the housing first and second contact carrier is prevented by the support member when the locking comb is inserted into the contact carrier and displaced into a locking position.

Durch eine derartige Ausgestaltung sowohl des Verriegelungskamms als auch des zugehörigen Gehäuses mit den Kontaktträgern ist es möglich, durch das Einschieben eines einzigen Verriegelungskammes sowohl die primärverriegelten elektrischen Kontaktelemente von zwei einander benachbarten Kontaktträgern sekundär zu verriegeln als auch gleichzeitig zwei einander benachbarte mit Rastelementen versehene Gehäusewandungen zu stützen. Natürlich kann der Verriegelungskamm noch weitere Zinken aufweisen, die eventuell ebenfalls Stützelemente aufweisen. Auch kann der Kontaktträger nur an einer Seite Rastelemente aufweisen oder auch an zwei möglicherweise einander gegenüberliegenden Seiten, so dass entsprechend nur eine Wandung pro Kontaktträger gestützt wird oder auch mehrere Wandungen.Such a configuration of both the locking comb and the associated housing with the contact carriers, it is possible by the insertion of a single locking comb both the primary locked electrical contact elements of two adjacent contact carriers secondary lock and at the same time to support two adjacent provided with locking elements housing walls , Of course, the locking comb may have further tines, which may also have support elements. Also, the contact carrier can only on one side locking elements or on two possibly opposite sides, so that according to only one wall per contact carrier is supported or even several walls.

Auch können bei dem hier vorliegenden Ausführungsbeispiel die beiden Kontaktträger identisch ausgebildet sein, wobei sie nur an einer ihrer sich in Einschubrichtung des Verriegelungskammes erstreckenden Längsseiten Rastelemente aufweisen. In vorteilhafter Weise weist nur an der zweiten Zinke ein Stützelement auf. Entsprechend können die beiden Kontaktträger in dem Gehäuse um einen vorbestimmten Punkt um 180° gedreht montiert werden.Also, in the present embodiment, the two contact carriers may be formed identically, wherein they only at one of their extending in the direction of insertion of the locking comb longitudinal sides Have locking elements. In an advantageous manner, only at the second prong a support element. Accordingly, the two contact carriers can be mounted rotated in the housing by a predetermined point by 180 °.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung wird ein Gehäuse zur Aufnahme eines Verriegelungskammes bereitgestellt, wobei das Gehäuse wenigstens ein erstes Rastelement aufweist. Das wenigstens eine erste Rastelement ist an einem zweiten Rastelement eines ersten Kontaktträgers für elektrische Kontaktelemente verrastbar. An dem Gehäuse ist ein Aufnahmeelement ausgebildet, wobei das Aufnahmeelement derart mit dem Stützelement des Verriegelungskammes zusammenwirkt, dass ein Lösen des ersten und des zweiten Rastelements voneinander verhindert ist, wenn der Verriegelungskamm in den Kontaktträger eingeführt und in eine Verriegelungsstellung verlagert ist.According to a further embodiment of the invention, a housing for receiving a locking comb is provided, wherein the housing has at least one first latching element. The at least one first latching element can be latched to a second latching element of a first contact carrier for electrical contact elements. On the housing, a receiving element is formed, wherein the receiving element cooperates with the supporting element of the locking comb such that a release of the first and second locking element is prevented from each other when the locking comb is inserted into the contact carrier and displaced into a locking position.

Eine derartige Ausgestaltung des Gehäuses mit eingesetzten Kontaktträgern bewirkt mit dem Stützelement des Verriegelungskammes, dass bei einem Trennen der Steckverbindung die Kontaktträger nicht aus dem Gehäuse gelöst werden können. Auch kann das Gehäuse in Verbindung mit dem Stützelement des Verriegelungskammes derart ausgestaltet sein, dass, wenn das Stützelement seine vorgesehene Position erreicht hat, ein Lösen des Kontaktträgers von dem Gehäuse nur durch eine Zerstörung der Rastelemente möglich ist. Eine Verlagerung des Verriegelungskammes in eine Entriegelungsstellung, die beispielsweise dadurch erzeugt werden kann, indem der Verriegelungskamm aus den Einführschlitzen des ersten Kontaktträgers entnommen ist, kann bewirken, dass nun der erste Kontaktträger dem Gehäuse entnommen werden kann. Wenn mehr als ein Kontaktträger in dem Gehäuse montiert ist, können nach dem Entfernen des Verriegelungskammes alle Kontakträger oder nur eine Teilmenge aller Kontaktträger dem Gehäuse entnommen werden.Such a configuration of the housing with inserted contact carriers causes with the support element of the locking comb that when disconnecting the connector, the contact carrier can not be released from the housing. Also, the housing may be configured in conjunction with the support element of the locking comb such that when the support element has reached its intended position, a release of the contact carrier of the housing is only possible by destruction of the locking elements. A displacement of the locking comb into an unlocking position, which can be generated, for example, by the locking comb is removed from the insertion slots of the first contact carrier, can cause now that the first contact carrier can be removed from the housing. If more than one contact carrier is mounted in the housing, all contact carriers or only a subset of all contact carriers can be removed from the housing after removal of the locking comb.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist das Gehäuse eine erste Gehäusewandung mit einer ersten Innenfläche und einer der ersten Innenfläche gegenüberliegende erste Außenfläche auf. Die erste Innenfläche begrenzt das Aufnahmeelement. An der ersten Außenfläche ist das erste Rastelement fest verbunden. Das Stützelement stützt derart die erste Innenfläche, dass bei einer Einwirkung einer Kraft auf das erste Rastelement ein Ausweichen der ersten Gehäusewandung mindestens im Bereich des ersten Rastelements in Richtung des Aufnahmeelements verhindert ist.According to a further exemplary embodiment of the invention, the housing has a first housing wall with a first inner surface and a first outer surface opposite the first inner surface. The first inner surface bounds the receiving element. At the first outer surface, the first locking element is firmly connected. The support element supports the first one in this way Inner surface, that in case of an action of a force on the first locking element, a deflection of the first housing wall is prevented at least in the region of the first locking element in the direction of the receiving element.

Somit kann das Stützelement die Gehäusewandung, an der das wenigstens eine erste Rastelement verbunden ist, sozusagen von der Rückseite aus stützen. Auch kann sich das Stützelement entlang der Innenfläche derart erstrecken, dass es mit dem wenigstens einen ersten Rastelement In Einschubrichtung und/oder Auszugsrichtung überlappt.Thus, the support member, the housing, where the at least one first locking element is connected, so to speak from the back support. Also, the support element along the inner surface may extend such that it overlaps with the at least one first locking element in the insertion direction and / or extension direction.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist das Gehäuse zur Aufnahme eines sich zu dem ersten Kontaktträger parallel erstreckenden zweiten Kontaktträgers ausgebildet. Das Gehäuse weist wenigstens ein drittes Rastelement auf, wobei das wenigstens eine dritte Rastelement an einem vierten Rastelement eines zweiten Kontaktträgers für elektrische Kontaktelemente verrastbar ist. Das Gehäuse weist eine sich zu der ersten Gehäusewandung parallel erstreckende zweite Gehäusewandung mit einer zweiten Innenfläche und einer der zweiten Innenfläche gegenüberliegende zweite Außenfläche auf, wobei die zweite Innenfläche das Aufnahmeelement begrenzt. An der zweiten Außenfläche ist das dritte Rastelement fest verbunden. Das Stützelement stützt derart die zweite Innenfläche, dass bei einer Einwirkung einer Kraft auf das dritte Rastelement ein Ausweichen der zweiten Gehäusewandung zumindest im Bereich des dritten Rastelements in Richtung des Aufnahmeelements verhindert ist.According to a further exemplary embodiment of the invention, the housing is designed to receive a second contact carrier which extends parallel to the first contact carrier. The housing has at least a third latching element, wherein the at least one third latching element can be latched to a fourth latching element of a second contact carrier for electrical contact elements. The housing has a second housing wall which extends parallel to the first housing wall and has a second inner surface and a second outer surface opposite the second inner surface, wherein the second inner surface delimits the receptacle element. On the second outer surface, the third locking element is firmly connected. The support member supports the second inner surface in such a way that, when a force acts on the third latching element, the second housing wall is prevented from deflecting at least in the region of the third latching element in the direction of the receiving element.

Somit ist es möglich, durch nur ein einziges Stützelement die erste und die zweite Gehäusewandung derart zu stützen, dass bei einer Krafteinwirkung auf das erste und das dritte Rastelement sowohl in der Auszugsrichtung, entlang der die Kontaktträger von den Gegenkontaktträgern getrennt werden, als auch quer dazu ein Lösen der beiden mit dem Gehäuse verrasteten Kontaktträger verhindert ist, wenn der Verriegelungskamm in den Kontaktträger eingeführt und in die Verriegelungsstellung verlagert ist.Thus, it is possible to support the first and the second housing wall by means of only a single support element in such a way that when the force acts on the first and the third latching element both in the extension direction, along which the contact carriers are separated from the mating contact carriers, as well as transversely thereto a release of the two latched with the housing contact carrier is prevented when the locking comb is inserted into the contact carrier and displaced into the locking position.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist das Aufnahmeelement des Gehäuses als Schlitz ausgebildet.According to a further embodiment of the invention, the receiving element of the housing is formed as a slot.

Ein Schlitz ist besonders einfach und kostengünstig herzustellen. Wenn das Gehäuse als ein Kunststoffspritzteil gestaltet ist, kann die Entformung des Gehäuses aus der Spritzgussform derart gestaltet sein, dass der Schlitz in dem Gehäuse ohne Einsatz von Schiebern ausgebildet werden kann. Hierbei können die den Schlitz begrenzenden beiden Innenwände eben und parallel zu einer Entformungsrichtung des Gehäuses aus der zugehörigen Spritzgussform ausgebildet sein.A slot is particularly easy and inexpensive to manufacture. If the housing is designed as a plastic injection molded part, the demolding of the housing from the injection mold can be designed such that the slot can be formed in the housing without the use of slides. In this case, the two inner walls delimiting the slot can be designed to be flat and parallel to a demoulding direction of the housing from the associated injection mold.

Gemäß einem weiteren Ausführungsbeispiel der Erfindung wird ein Steckverbinder mit einem Gehäuse und einem Verriegelungskamm bereitgestellt, wobei an dem Gehäuse wenigstens ein Kontaktträger mit wenigstens einem elektrischen Kontaktelement verrastet ist. In Einführschlitze des wenigstens einen verrasteten Kontaktträgers ist ein Verriegelungskamm eingeführt und in eine Verriegelungsstellung verlagert. Das Stützelement wirkt derart mit Aufnahmeelement zusammen, dass ein Lösen des mit dem Gehäuse verrasteten Kontaktträgers verhindert ist.According to a further embodiment of the invention, a connector is provided with a housing and a locking comb, wherein at least one contact carrier is latched to the housing with at least one electrical contact element. In insertion slots of the at least one latched contact carrier, a locking comb is inserted and displaced into a locking position. The support member cooperates with receiving element in such a way that a release of the latched to the housing contact carrier is prevented.

Es wird angemerkt, dass Gedanken zu der Erfindung hierin im Zusammenhang mit einem Verriegelungskamm, einem Gehäuse und einem Steckverbinder beschrieben sind. Einem Fachmann ist hierbei klar, dass die einzelnen beschriebenen Merkmale auf verschiedene Weise miteinander kombiniert werden können, um so auch zu anderen Ausgestaltungen der Erfindung zu führen.It is noted that thoughts on the invention are described herein in the context of a locking crest, a housing, and a connector. It is clear to a person skilled in the art that the individual features described can be combined with one another in various ways so as to also lead to other embodiments of the invention.

Detaillierte Beschreibung einer beispielhaften AusführungsformDetailed Description of an Exemplary Embodiment

Figur 1 zeigt einen Steckverbinder 2 mit einem Gehäuse 4, einem Kontaktträger 6 und einem Verriegelungskamm 14 in einer 3D-Querschnittsdarstellung. In dem Kontaktträger 6 befinden sich Kontaktelementaufnahmekammern 8, in denen sich hier nicht dargestellte Kontaktelemente befinden, die mit dem Kontaktträger 6 primärverriegelt sind. Die Kontaktelementaufnahmekammern 8 gruppieren sich in eine erste Reihe 10 und eine dazu parallel verlaufende zweite Reihe 12. Die elektrischen Kontaktelemente werden in die Kontaktelementaufnahmekammern 8 entgegen einer Auszugsrichtung A eingebracht. Entlang der Auszugsrichtung A wird der Steckverbinder 2 von einem Gegensteckverbinder, welcher hier nicht dargestellt ist, getrennt. Der Gegensteckverbinder kann beispielsweise eine Anordnung elektrischer Kontaktelemente an einem Steuergerät sein. In der hier gezeigten Darstellung befindet sich der Verriegelungskamm 14 in seiner Verrieglungsstellung. Hierbei ist der Verriegelungskamm 14 mit dem Gehäuse 4 hier nicht sichtbar verriegelt. Der Verriegelungskamm 14 besteht in dem hier vorliegenden Ausführungsbeispiel aus einem Verriegelungskammrücken 16 sowie einer mit dem Verriegelungskammrücken 16 fest verbundenen ersten 18, zweiten 20 und dritten Zinke 22. Hierbei ist die zweite Zinke 20 zwischen der ersten 18 und der dritten Zinke 22 angeordnet. Die zweite Zinke 20 besitzt ferner ein Stützelement 24, welches als ein sich in der Auszugsrichtung A erstreckender und mit der zweiten Zinke 20 unlösbar verbundener Steg ausgebildet ist. Weiterhin besitzen die erste 18 und die dritte Zinke 22 jeweils eine Nut 26 und die zweite Zinke 20 zwei Nuten 26, wobei sich die Nuten 26 an einer dem Gegenstecker zugewandten Unterseite befinden. Die Nuten 26 haben die Aufgabe, die Zinken 18, 20, 22 mittels hier nicht dargestellter und mit dem Kontaktträger 6 fest verbundener Vorsprünge zu führen, wenn die Zinken 18, 20, 22 in beidseits an Längsseiten 27 des Kontaktträgers 6 ausgebildete Einführschlitze 28 eingeführt werden. Durch das Einführen der Zinken 18, 20, 22 in die Einführschlitze 28 entlang einer Einschubrichtung E, welche sich quer zu der Auszugsrichtung A entlang der Längsseiten 27 des Kontaktträgers 6 erstreckt, werden die primärverriegelten elektrischen Kontaktelemente sekundär verriegelt. Ein Fehlen derartiger Führungselemente wie die Nut 26 in Verbindung mit den Vorsprüngen könnte bewirken, dass die erste (18) oder die dritte Zinke (22) durch ein nicht ordnungsgemäß primärverriegeltes Kontaktelement aus dem Einführschlitz (28) geschoben wird. Ferner erfolgt durch die Anordnung von zwei Nuten 26 in der zweiten Zinke 20 eine Zuordnung von je einer Nut 26 zu dem ersten Kontaktträger 6 und einem zu dem ersten Kontaktträger 6 parallel angeordneten zweiten Kontaktträger. Somit ist durch die formschlüssige Verbindung der zweiten Zinke 20 sowohl an dem ersten Kontaktträger 6 als auch an dem zweiten Kontaktträger verhindert, dass durch eine Krafteinwirkung auf wenigstens einen der Kontaktträger die Sekundärverriegelung möglicherweise nicht mehr sichergestellt sein könnte. Der Verriegelungskamm 14 ist mit dem Gehäuse 4 hier nicht dargestellt formschlüssig verrastet. In dem Gehäuse 4 befindet sich ein erster Hohlraum 30 und ein zweiter Hohlraum 32. In dem ersten Hohlraum 30 ist der Kontaktträger 6 angeordnet, der zweite Hohlraum 32 ist ohne Kontaktträger dargestellt. Der erste Hohlraum 30 ist durch eine erste Gehäusewandung 34 begrenzt. Der zweite Hohlraum 32 ist durch eine zu der ersten Gehäusewandung 34 sich parallel zu der ersten Gehäusewandung 34 und zu dieser benachbart erstreckenden zweiten Gehäusewandung 36 begrenzt. Zwischen der ersten Gehäusewandung 34 und der zweiten Gehäusewandung 36 ist ein Aufnahmeelement 38 angeordnet, welches in dem hier vorliegenden Ausführungsbeispiel als Schlitz 40 ausgebildet ist, der sich in die Auszugsrichtung A erstreckt. Der Schlitz 40 wird begrenzt durch eine erste Innenfläche 42 der ersten Gehäusewandung 34 und eine sich parallel zu der ersten Innenfläche 42 erstreckende zweite Innenfläche 44 der zweiten Gehäusewandung 36. Der ersten Innenfläche 42 gegenüberliegend und sich zu dieser im Wesentlichen parallel erstreckend ist eine erste Außenfläche 46 ausgebildet. Zu der zweiten Innenfläche 44 erstreckt sich ebenfalls im Wesentlichen parallel eine zweite Außenfläche 48. Deutlich sichtbar ist, dass die erste Gehäusewandung 34 und die zweite Gehäusewandung 36 schmal gegenüber den restlichen Gehäusewandungen ausgeführt sind. An der ersten Außenfläche 46 ist wenigstens ein erstes Rastelement 50 angeordnet. An der zweiten Außenfläche 48 ist wenigstens ein drittes Rastelement 54 ausgebildet. Das erste 50 und das dritte Rastelement 54 sind jeweils als Vorsprünge ausgebildet. Weiterhin besitzt der Kontaktträger 6 an der der ersten Gehäusewandung 34 zugewandten Längsseite 27 mindestens ein zweites Rastelement 52, wobei das zweite Rastelement 52 mit dem Kontaktträger 6 fest verbunden ist. FIG. 1 shows a connector 2 with a housing 4, a contact carrier 6 and a locking comb 14 in a 3D cross-sectional view. In the contact carrier 6 are located Kontaktelementaufnahmekammern 8, in which there are not shown contact elements, which are primarily locked with the contact carrier 6. The contact element receiving chambers 8 are grouped into a first row 10 and a second row 12 extending parallel thereto. The electrical contact elements are introduced into the contact element receiving chambers 8 counter to an extension direction A. Along the extension direction A of the connector 2 by a mating connector, which is not shown here, separated. The mating connector can be, for example, an arrangement of electrical contact elements on a control unit. In the illustration shown here, the locking comb 14 is in its Verrieglungsstellung. Here, the locking comb 14 is not visibly locked to the housing 4 here. The locking comb 14 consists in the present embodiment of a locking comb back 16 and a fixed to the locking comb back 16 first 18, second 20 and third prong 22. Here, the second prong 20 between the first 18 and the third prong 22 is arranged. The second prong 20 also has a support element 24, which is designed as a web extending in the extension direction A and connected inseparably to the second prong 20. Furthermore, the first 18 and the third prong 22 each have a groove 26 and the second prong 20 two grooves 26, wherein the grooves 26 are located on a mating connector facing the bottom. The grooves 26 have the task to guide the tines 18, 20, 22 by means not shown here and with the contact carrier 6 firmly connected projections when the tines 18, 20, 22 inserted in both sides on the longitudinal sides 27 of the contact carrier 6 insertion slots 28 , By inserting the prongs 18, 20, 22 into the insertion slots 28 along an insertion direction E, which extends transversely to the extension direction A along the longitudinal sides 27 of the contact carrier 6, the primary-locked electrical contact elements are locked secondarily. Failure of such guide members as the groove 26 in conjunction with the protrusions could cause the first (18) or third prong (22) to be pushed out of the insertion slot (28) by improperly primary locked contactor. Furthermore, by the arrangement of two grooves 26 in the second prong 20 an assignment of a respective groove 26 to the first contact carrier 6 and to the first contact carrier 6 arranged in parallel second contact carrier. Thus, it is prevented by the positive connection of the second prong 20 both on the first contact carrier 6 and on the second contact carrier, that the secondary locking could possibly no longer be ensured by a force acting on at least one of the contact carrier. The locking comb 14 is not shown here positively locked with the housing 4. In the housing 4 is a first cavity 30 and a second cavity 32. In the first cavity 30 of the contact carrier 6 is arranged, the second cavity 32 is shown without contact carrier. The first cavity 30 is bounded by a first housing wall 34. The second cavity 32 is delimited by a second housing wall 36 extending parallel to the first housing wall 34 and adjacent to the first housing wall 34. Between the first housing wall 34 and the second housing wall 36, a receiving element 38 is arranged, which is formed in the present embodiment as a slot 40 which extends in the extension direction A. The slot 40 is bounded by a first inner surface 42 of the first housing wall 34 and a second inner surface 44 of the second housing wall 36 extending parallel to the first inner surface 42. Opposing the first inner surface 42 and extending substantially parallel thereto is a first outer surface 46 educated. A second outer surface 48 also extends substantially parallel to the second inner surface 44. It can clearly be seen that the first housing wall 34 and the second housing wall 36 are made narrow relative to the remaining housing walls. At least a first latching element 50 is arranged on the first outer surface 46. At least a third latching element 54 is formed on the second outer surface 48. The first 50 and the third locking element 54 are each formed as projections. Furthermore, the contact carrier 6 has at least one second latching element 52 on the longitudinal side 27 facing the first housing wall 34, wherein the second latching element 52 is fixedly connected to the contact carrier 6.

Die hier gewählte Darstellung zeigt einen montierten Steckverbinder 2. Somit ist der Kontaktträger 6 mit dem Gehäuse 4 derart verrastet, dass das wenigstens eine erste Rastelement 50 und das wenigstens eine zweite Rastelement 52 verrastend zusammenwirken. Sichtbar ist, dass die Verrastung des Kontaktträgers 6 mit dem Gehäuse 4 lediglich an einer der beiden Längsseite 27 erfolgt ist. Die andere der beiden Längsseiten 27 weist jedoch nicht notwendigerweise keine Rastelemente auf. Die Verrastung eines weiteren Kontaktträgers mit dem Gehäuse 4, der in dem zweiten Hohlraum 32 eingebracht wäre, erfolgt ebenso. Ferner ist in der hier gewählten Darstellung der Verriegelungskamm 14 in seine Verriegelungsstellung verlagert. Somit ist in den Schlitz 40 das stegartig ausgebildete Stützelement 24 eingebracht, wobei das Stützelement 24 das erste 50 und das dritte Rastelement 54 in Auszugsrichtung A und in Einschubrichtung E zumindest teilweise überlappt. Natürlich kann die Ausgestaltung auch derart gewählt werden, dass das Stützelement 24 das erste 50 und das dritte Rastelement 54 in der Auszugsrichtung A nicht überlappt. Bei einer derartigen Ausgestaltung kann dann eine Überlappung des ersten 50 und des dritten Rastelements 54 durch das Stützelement 24 sinnvoll sein. Das Stützelement 24 stützt die erste Innenfläche 42 derart, dass, wenn der Steckverbinder 2 in Auszugsrichtung A von dem hier nicht dargestellten Gegensteckverbinder getrennt wird, eine auf das erste Rastelement 50 durch das zweite Rastelement 52 entgegen der Auszugsrichtung A ausgeübte Kraft F nicht dazu führt, dass die erste Gehäusewandung 34 quer zu der Kraft F in Ausweichrichtung B, also in Richtung des Aufnahmeelements 38, ausweichen kann. Das Stützelement 24 stützt ferner die zweite Innenfläche 44 derart, dass eine auf das dritte Rastelement 54 durch ein viertes Rastelement des zweiten hier nicht dargestellten Kontaktträgers entgegen der Auszugsrichtung A ausgeübte Kraft F nicht dazu führt, dass die zweite Gehäusewandung 34 quer zu der Kraft F in Richtung des Aufnahmeelements 38, ausweichen kann. Somit ist ein Lösen des Kontaktträgers 6 sowie des zweiten Kontaktträgers aus dem Gehäuse 4 bei einem Trennen des Steckverbinders 2 von einem Gegensteckverbinder durch das Stützelement 24 des Verriegelungskamms 14 wirkungsvoll verhindert. Weiterhin wird die Flexibilität der ersten 34 und/oder zweiten Gehäusewandung 36 aufgrund ihrer Schmalheit gegenüber den anderen Gehäusewandungen genutzt, um den Kontaktträger 6 mit geringem Aufwand in die verrastende Position zu verbringen. Durch das Einbringen des Verriegelungskamms 14 mit dem Stützelement 24 wird die Flexibilität der ersten 34 und der zweiten Gehäusewandung 36 unterbunden. Das Gehäuse 4, der/die Kontakträger 6 und das Verriegelungskamm 14 sind einstückig und aus elektrisch nicht leitfähigem Kunststoff im Spritzgussverfahren hergestellt.The selected representation here shows a mounted connector 2. Thus, the contact carrier 6 is locked to the housing 4 such that the at least a first latching element 50 and the at least one second latching element 52 cooperating latching. It can be seen that the latching of the contact carrier 6 with the housing 4 is effected only on one of the two longitudinal sides 27. However, the other of the two longitudinal sides 27 does not necessarily have no locking elements. The latching of a further contact carrier with the housing 4, which would be introduced into the second cavity 32, also takes place. Furthermore, in the representation selected here, the locking comb 14 is displaced into its locking position. Thus, in the slot 40, the web-like support member 24 is introduced, wherein the support member 24, the first 50 and the third locking element 54 in the extension direction A and in the insertion direction E at least partially overlaps. Of course, the configuration can also be selected such that the support element 24 does not overlap the first 50 and the third latching element 54 in the extension direction A. In such a configuration, an overlap of the first 50 and the third locking element 54 by the support member 24 may then be useful. The support member 24 supports the first inner surface 42 such that, when the connector 2 is separated in the extension direction A from the mating connector not shown here, a force F exerted on the first detent element 50 by the second detent element 52 against the extension direction A does not cause in that the first housing wall 34 can dodge transversely to the force F in the deflection direction B, ie in the direction of the receiving element 38. The support member 24 further supports the second inner surface 44 such that a force F exerted on the third latching element 54 by a fourth latching element of the second contact carrier, not shown here, against the extension direction A does not cause the second housing wall 34 to extend transversely to the force F in FIG Direction of the receiving element 38, can dodge. Thus, a release of the contact carrier 6 and the second contact carrier from the housing 4 at a separation of the connector 2 by a mating connector by the support member 24 of the locking comb 14 is effectively prevented. Furthermore, the flexibility of the first 34 and / or second housing 36 is used because of their narrowness compared to the other housing walls to spend the contact carrier 6 with little effort in the latching position. By introducing the locking comb 14 with the support member 24, the flexibility of the first 34 and the second housing 36 is prevented. The housing 4, the / the Contact carrier 6 and the locking comb 14 are made in one piece and made of electrically non-conductive plastic by injection molding.

Zur Montage des Steckverbinders 2 wird zunächst eine hier nicht dargestellte Radialdichtung an das Gehäuse 4 angeordnet. Anschließend werden in dem hier gezeigten Ausführungsbeispiel zwei Kontaktträger derart in das Gehäuse 4 eingeführt, bis das wenigstens eine erste Rastelement 50 des Gehäuses 4 mit dem wenigstens einen zweiten Rastelement 52 des Kontaktträgers 6 und das wenigstens eine dritte Rastelement 54 des Gehäuses 4 mit dem wenigstens einen vierten Rastelement des zweiten Kontaktträgers verrastet sind. Anschließend wird eine Mattendichtung in das Gehäuse 4 eingebracht, welche durch eine mit dem Gehäuse 4 verrastende hier nicht dargestellte Halteplatte fixiert wird. Anschließend werden die Kontaktträger mit elektrischen Kontaktelementen bestückt, wobei die elektrischen Kontaktelemente mit den Kontaktträgern primärverriegeln. Abschließend wird der Verriegelungskamm 14 in das Gehäuse 4 und die Kontaktträger eingeführt, um die primärverriegelten elektrischen Kontaktelemente sekundärzuverriegeln und die erste 34 und die zweite Gehäusewandung 36 mittels des Stützelements 24 zu stützen. Ferner kann der in den ersten Hohlraum 30 eingebrachte Kontaktträger 6 identisch sein zu dem Kontaktträger, welcher in den zweiten Hohlraum 32 eingebracht ist, wobei in dem hier gezeigten Ausführungsbeispiel die beiden Kontaktträger aufgrund der Lage des wenigstens einen ersten 50 und des wenigstens einen dritten Rastelements 54 um einen vorbestimmten Punkt um 180° zueinander gedreht angeordnet sind. Die Montage der Kontaktträger in das Gehäuse 4 erfordert nur geringen Kraftaufwand in Richtung der Auszugsrichtung A, da sowohl die erste Gehäusewandung 34 als auch die zweite Gehäusewandung 36 in Richtung des Aufnahmeelements 38, respektive des Schlitzes 40, ausweichen können. Nach der Montage der Kontaktträger 6 in dem Gehäuse 4 wird der Verriegelungskamm 14 mit seinem Zinken 18, 20, 22 an die Kontaktträger 6 verbunden. Hierbei werden die erste 18 und die zweite Zinke 20 in den ersten sich in dem ersten Hohlraum 30 befindlichen ersten Kontaktträger 6 und die zweite 20 und die dritte Zinke 22 in den sich in dem zweiten Hohlraum 32 befindlichen zweiten Kontaktträger in deren jeweilige Einführschlitze 28 eingeführt. Durch ein Verlagern des Verriegelungskamms 14 längs der Längsseite 27 der Kontaktträger 6 in Einschubrichtung E in die Verriegelungsstellung werden durch die Zinken 18, 20, 22 die jeweiligen elektrischen Kontaktelemente sekundärverriegelt. Gleichzeitig wird beim Verlagern des Verriegelungskamms 14 in seine Verriegelungsstellung das Stützelement 24 in den Schlitz 40 eingebracht. Hierbei stützt das Stützelement 24 sowohl die erste 34 als auch die zweite Gehäusewandung 36 derart, dass bei einer Einwirkung der Kraft F auf die Rastelemente 50, 54 die beiden Gehäusewandungen 34, 36 nicht in der Ausweichrichtung B in Richtung des Schlitzes 40 ausweichen können.For mounting the connector 2, a radial seal, not shown here, is first arranged on the housing 4. Subsequently, in the embodiment shown here, two contact carriers are inserted into the housing 4 until the at least one first detent element 50 of the housing 4 with the at least one second detent element 52 of the contact carrier 6 and the at least one third detent element 54 of the housing 4 with the at least one fourth latching element of the second contact carrier are latched. Subsequently, a mat seal is introduced into the housing 4, which is fixed by a latching with the housing 4 not shown here holding plate. Subsequently, the contact carriers are equipped with electrical contact elements, wherein the electrical contact elements with the contact carriers primary lock. Finally, the locking crest 14 is inserted into the housing 4 and the contact carriers to secondarily lock the primary locked electrical contact elements and to support the first 34 and second housing walls 36 by means of the support member 24. Furthermore, the contact carrier 6 introduced into the first cavity 30 may be identical to the contact carrier which is introduced into the second cavity 32, wherein in the exemplary embodiment shown here the two contact carriers due to the position of the at least one first 50 and the at least one third locking element 54 are arranged rotated by a predetermined point by 180 ° to each other. The mounting of the contact carrier in the housing 4 requires only little effort in the direction of extension direction A, since both the first housing wall 34 and the second housing 36 in the direction of the receiving element 38, respectively of the slot 40, can escape. After mounting the contact carrier 6 in the housing 4, the locking comb 14 is connected with its tines 18, 20, 22 to the contact carrier 6. In this case, the first 18 and the second prong 20 are inserted into the first first contact carrier 6 located in the first cavity 30 and the second 20 and the third prong 22 are inserted into the second contact carrier located in the second cavity 32 in their respective insertion slots 28. By displacing the locking comb 14 along the longitudinal side 27 of the contact carrier 6 in the insertion direction E in the locking position by the tines 18, 20, 22, the respective secondarily locked electrical contact elements. At the same time, the support element 24 is inserted into the slot 40 when displacing the locking comb 14 into its locking position. In this case, the support member 24 supports both the first 34 and the second housing 36 such that upon an action of the force F on the locking elements 50, 54, the two housing walls 34, 36 can not dodge in the direction of the slot 40 in the direction of deflection B.
