Description

Elektrischer Steckverbinder  Electrical connector

Thus, for example, DE 10 2004 054 203 A1 discloses an electrical plug connector of the generic type in which an insulation displacement plug contact strip is provided.

Offenbarung der Erfindung Disclosure of the invention
Vorteile der Erfindung Advantages of the invention
Der erfindungsgemäße elektrischer Steckverbinder mit den Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass der Verriegelungsbügel nicht an einem Gehäuse befestigt werden muss, sondern als separates Bauteil handhabbar ist. Dies ist deshalb vorteilhaft, weil beispielsweise bei einer Beschädigung des Verriegelungsbügels leicht ein Austausch des Verriegelungsbügels durch einen unbeschädigten Verriegelungsbügel möglich ist. Darüber hinaus ist der erfindungsgemäße Verriegelungsbügel wesentlich massiver und stabiler ausgebildet als die aus dem Stand der Technik bekannten Verriegelungsbügel. Von besonderem Vorteil ist es, dass der erfindungsgemäße Verriegelungsbügel insbesondere auch ein Sekundärverriegelungs- bügel sein kann, der eine bereits verriegelte Steckverbindung zusätzlich sichert, so dass diese in besonders kritischen Umgebungen (beispielsweise starken Vibrationen ausgesetzte Umgebungen u. dgl.) einsetzbar ist. Als Pri- märverriegelungsmittel sind beispielsweise eine am zweiten Gehäuseteil angeordnete Zunge mit einem Rasthaken und eine im ersten Gehäuseteil angeordnete Öffnung vorgesehen, in die der Rasthaken eingreift. Erfindungsgemäß ist ein Verriegelungsbügel vorgesehen, der während er den ersten oder zweiten Gehäuseteil im ineinandergesteckten Zustand der beiden Gehäuseteile im Wesentlichen parallel zur Steckrichtung umgreift, in/an dem zweiten bzw. ersten Gehäuseteil verriegelbar ist. Hierdurch wird ein besonders stabiler Verbund der beiden ineinandergesteckten Steckverbinderteile realisiert. The electrical connector according to the invention with the features of claim 1 has the advantage that the locking bracket does not have to be attached to a housing, but is manageable as a separate component. This is advantageous because, for example, in case of damage to the locking bracket easy replacement of the locking bracket by an undamaged locking bracket is possible. In addition, the locking bracket according to the invention is much more solid and stable than the known from the prior art locking bracket. It is particularly advantageous that the locking clip according to the invention can in particular also be a secondary locking clip, which additionally secures an already locked plug connection, so that it can be used in particularly critical environments (eg environments exposed to strong vibrations and the like). As primary locking means, for example, a tongue arranged on the second housing part with a latching hook and an opening arranged in the first housing part are provided, into which the latching hook engages. According to the invention a locking bracket is provided, which surrounds the first or second housing part in the nested state of the two housing parts substantially parallel to the plug-in direction, in / on the second or first housing part can be locked. As a result, a particularly stable composite of the two nested connector parts is realized.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen Steckverbinders möglich. The measures listed in the dependent claims advantageous refinements and improvements of the claim 1 connector are possible.
So sieht eine vorteilhafte Ausgestaltung vor, dass in dem ersten oder zweiten Gehäuseteil im Wesentlichen parallel zur Steckrichtung verlaufende Führungselemente zur Führung von Bügelarmen des Verriegelungsbügels angeordnet sind. Auf diese Weise wird eine präzise Führung des Verriegelungsbügels an dem einen Gehäuseteil realisiert und gleichzeitig auch eine Befestigung der Bügelarme des Verriegelungsbügels an dem Gehäuseteil ermöglicht. Thus, an advantageous embodiment provides that in the first or second housing part substantially parallel to the insertion direction extending guide elements for guiding ironing arms of the locking bracket are arranged. In this way, a precise guidance of the locking bracket is realized on the one housing part and at the same time allows attachment of the hanger arms of the locking bracket to the housing part.
Darüber hinaus ist vorteilhafterweise vorgesehen, dass in dem zweiten bzw. ersten Gehäuseteil Rastelemente zur Verrastung mit den an den Bügelarmen angeordneten Gegen rastelementen vorgesehen sind. Die an den Bügelarmen angeordneten Gegenrastelemente verrasten mit den Rastelementen, wobei durch die Führungselemente eine präzise Führung und damit auch eine präzise Verrastung der Rastelemente aneinander sichergestellt ist. In addition, it is advantageously provided that latching elements are provided for latching with the arranged on the bail arms counter locking elements in the second or first housing part. The arranged on the bow arms counter-locking elements engage with the locking elements, which is ensured by the guide elements precise guidance and thus a precise locking of the locking elements to each other.
Rein prinzipiell kann der Verriegelungsbügel auf unterschiedliche Art und Weise ausgebildet sein. Eine besonders vorteilhafte Ausgestaltung sieht vor, dass der Verriegelungsbügel U-förmig ausgebildet ist mit zwei im Wesentlichen rechtwinklig von einer Basis abgewinkelten U-Schenkeln. Eine solche U-förmige Ausbildung kommt besonders vorteilhaft bei den zumeist quaderförmigen Steckverbindergehäuseteilen zum Einsatz. Purely in principle, the locking bracket can be designed in different ways. A particularly advantageous embodiment provides that the locking bracket is U-shaped with two substantially perpendicularly bent from a base U-legs. Such a U-shaped design is particularly advantageous in the mostly cuboid connector housing parts used.
Sehr vorteilhaft ist vorgesehen, dass die U-Schenkel als Führungselemente auf ihrer dem ersten oder zweiten Gehäuseteil jeweils zugewandten Innenseite Nuten aufweisen, in die an sie angepasste und an den parallel zur Steck- richtung verlaufenden Außenseiten angeordnete Vorsprünge gleitver- schieblich eingreifen. Die Führungselemente werden also durch Nuten und durch in sie eingreifende Vorsprünge realisiert. Dies ermöglicht zum einen eine präzise Führung des Verriegelungsbügels, zum anderen aber auch eine optimale Befestigung des Verriegelungsbügels an dem die Vorsprünge aufweisenden Gehäuseteil. It is advantageously provided that the U-legs have grooves as guide elements on their inner side facing the first or second housing part, into which slots they are adapted and parallel to the plug-in connector. Direction extending outer sides arranged projections slidably engage. The guide elements are thus realized by grooves and by engaging in them projections. This allows for a precise guidance of the locking bracket, on the other hand, but also an optimal attachment of the locking bracket to the projections having the housing part.
Besonders bevorzugt ist vorgesehen, dass die U-Schenkel als Gegenrast- elemente an ihren Enden Rasthaken aufweisen, die mit an dem ersten oder zweiten Gehäuseteil angeordneten Rastnasen zusammenwirken. Die Zusammenwirkung der Nuten zusammen mit den Vorsprüngen und der Rasthaken mit den an dem Gehäuseteil angeordneten Rastnasen ermöglicht eine präzise Führung der U-Schenkel und damit auch ein präzises Einrasten der Rasthaken in die Rastnasen. Um dieses Einrasten zu erleichtern, ist vorteilhafterweise vorgesehen, dass die Rasthaken und die Rastnasen auf ihren einander zugewandten Seiten aneinander angepasste, schräg verlaufende Gleitflächen aufweisen. It is particularly preferred that the U-legs have latching hooks at their ends as counter-latching elements, which latching elements interact with latching lugs arranged on the first or second housing part. The interaction of the grooves together with the projections and the latching hooks with the arranged on the housing part locking lugs allows precise guidance of the U-legs and thus a precise engagement of the latching hooks in the locking lugs. In order to facilitate this latching, it is advantageously provided that the latching hooks and the latching lugs have, on their mutually facing sides, mutually adapted oblique sliding surfaces.
Der Verriegelungsbügel kann rein prinzipiell aus den unterschiedlichsten Materialien bestehen. Besonders vorteilhaft ist er als Kunststoffteil ausgebildet, das nicht nur leicht herzustellen ist, sondern insbesondere auch leicht ist und gleichzeitig Isolationseigenschaften aufweist. The locking bracket can consist purely principally of a wide variety of materials. It is particularly advantageously designed as a plastic part, which is not only easy to produce, but in particular is also lightweight and at the same time has insulating properties.

Ausführungsformen der Erfindung Embodiments of the invention
Ein elektrischer Steckverbinder, dargestellt in den Fig. 1 bis 3 in verschiedenen Steckzuständen, weist ein erstes Gehäuseteil 100 auf, in dem erste Steckkontaktelemente, beispielsweise Messerkontaktelemente 105 angeordnet sind. An dieses erste Gehäuseteil 100 angepasst ist ein zweites Gehäuseteil 200, welches in das erste Gehäuseteil 100 auf an sich bekannte Weise steckbar ist und in dem entsprechende Gegenkontaktelemente, also (hier nicht sichtbare) Federkontaktelemente angeordnet sind. An electrical connector, shown in FIGS. 1 to 3 in different states of insertion, has a first housing part 100 in which first plug contact elements, such as blade contact elements 105 are arranged. Adapted to this first housing part 100 is a second housing part 200, which can be plugged into the first housing part 100 in a manner known per se and in which corresponding mating contact elements, ie spring contact elements (not visible here), are arranged.
Darüber hinaus ist ein Verriegelungsbügel 300 vorgesehen, der im Wesentlichen eine U-förmige Gestalt aufweist mit U-Schenkeln 301 , 302. Die Innenseite der U-Schenkel 301 , 302 weisen U-förmige Nuten 310 auf, welche an entsprechende, hier quaderartig ausgebildete Vorsprünge 210, die an den Außenseiten des zweiten Gehäuseteils 200 des Steckverbinders angeformt sind, angepasst sind, derart, dass die quaderartigen Vorsprünge 210 in den Nuten 310 des Verbindungsbügels 300 gleitverschieblich sind. An den jeweiligen Enden der U-Schenkel 301 , 302 sind Rasthaken 320 ausgebildet, deren Vorderseiten, also deren den beiden Gehäuseteilen 100, 200 zugewandte Seiten, jeweils eine Schräge 322 aufweisen. Diese schrägverlaufenden Flä- chen 322 sind an entsprechende schrägverlaufende Flächen 122 von Rastnasen 120 angepasst, die an dem ersten Gehäuseteil 100 angeordnet sind. In addition, a locking bracket 300 is provided, which has a substantially U-shaped configuration with U-legs 301, 302. The inside of the U-legs 301, 302 have U-shaped grooves 310, which at corresponding, here parallelepiped-like projections 210, which are formed on the outer sides of the second housing part 200 of the connector, are adapted such that the cuboid projections 210 in the grooves 310 of the connecting bracket 300 are slidable. At the respective ends of the U-legs 301, 302 latching hooks 320 are formed, the front sides, ie the two housing parts 100, 200 facing sides, each having a slope 322. These sloping surfaces Chen 322 are adapted to corresponding inclined surfaces 122 of locking lugs 120, which are arranged on the first housing part 100.
Fig. 1 zeigt den ungesteckten Zustand der beiden Gehäuseteile 100, 200, wohingegen Fig. 2 den ineinandergesteckten Zustand der beiden Gehäuseteile 100, 200 zeigt. Fig. 1 und Fig. 2 zeigen jeweils den unverriegelten Zustand, wohingegen Fig. 3 den gesteckten und verriegelten Zustand der beiden Gehäuseteile 100, 200 zeigt. Wie Fig. 1 und Fig. 2 zu entnehmen ist, weist das Gehäuseteil 200 eine federnde Zunge 280 mit einer Rastnase 290 auf, die in eine im Gehäuseteil 100 vorgesehene Öffnung 180 eingreift. Zunge 280, Rastnase 290 und Öffnung 180 wirken so bereits als Primärverriege- lungsmittel, die eine Verriegelung der beiden Gehäuseteile 200 und 100 aneinander sicherstellen. Diese Verriegelung wird zusätzlich gesichert mit dem Verriegelungsbügel 300, der in diesem Fall als Sekundärverriegelungsmittel wirkt. Nachdem nämlich die beiden Gehäuseteile 100, 200 ineinander- gesteckt wurden, wird der Verriegelungsbügel 300 über das zweite Gehäuseteil 200 geschoben, wobei die Vorsprünge 210 in die Nuten 310 eingreifen und in den Nuten 310 gleiten. Sodann verrasten die Rasthaken 320 an oder mit den Rastnasen 120 des ersten Gehäuseteils 100. Die Verrastung erfolgt während das zweite Gehäuseteil 200 durch den Verriegelungsbügel 300 gesichert ist. Dabei erweisen sich die großflächig angeordneten Vorsprünge 210, die die Nuten 310 im verrasteten Zustand praktisch vollständig ausfüllen als sehr vorteilhaft. Sie ermöglichen nicht nur eine präzise Führung der beiden U-Schenkel 301 , 302 und damit auch eine präzise Führung der Rasthaken 320 in Richtung der Rastnasen 120. Sie ermöglichen auch ein sicheres Halten des zweiten Gehäuseteils 200, insbesondere wenn ein Druck senkrecht zur Steckrichtung ausgeübt wird, was rein prinzipiell möglich ist, da die Abführung der elektrischen Leiter senkrecht zu der Zeichenebene erfolgt, indem nämlich in die Öffnung 207 beispielsweise ein Flachbandkabel oder auch einzelne Drähte eingeführt werden, die in dem zweiten Gehäuseteil 200 beispielsweise auf die in der DE 10 2004 054 203 A1 beschriebene Weise mittels Schneidklemmkontakten kontaktiert werden. Das Gehäuseteil 100 ist dagegen beispielsweise auf einer Leiterplatte angeordnet und die Kontaktelemente sind über entsprechende Leiterbahnen auf der Leiterplatte kontaktiert. Rein prinzipiell könnte aber auch das Gehäuseteil 100 so ausgebildet sein, dass die elektrischen Leiter beispielsweise wie im Falle des Gehäuseteils 200 senkrecht von der Zeichenebene weggeführt sind oder auch parallel zur Zeichenebene, also parallel zur Steckrichtung. Fig. 1 shows the unmated condition of the two housing parts 100, 200, whereas Fig. 2 shows the nested state of the two housing parts 100, 200. Fig. 1 and Fig. 2 each show the unlocked state, whereas Fig. 3 shows the inserted and locked state of the two housing parts 100, 200. As can be seen from FIGS. 1 and 2, the housing part 200 has a resilient tongue 280 with a latching nose 290, which engages in an opening 180 provided in the housing part 100. Tongue 280, locking lug 290 and opening 180 thus already act as primary locking means, which ensure a locking of the two housing parts 200 and 100 to one another. This lock is additionally secured with the locking bracket 300, which in this case acts as a secondary locking means. Namely, after the two housing parts 100, 200 have been inserted into each other, the locking bracket 300 is pushed over the second housing part 200, wherein the projections 210 engage in the grooves 310 and slide in the grooves 310. Then lock the latch hooks 320 on or with the locking lugs 120 of the first housing part 100. The locking takes place while the second housing part 200 is secured by the locking bracket 300. In this case, the projections 210 arranged over a large area, which virtually completely fill the grooves 310 in the latched state, prove to be very advantageous. They not only allow a precise guidance of the two U-legs 301, 302 and thus also a precise guidance of the latching hooks 320 in the direction of the latching lugs 120. They also allow a secure holding of the second housing part 200, in particular when a pressure is exerted perpendicular to the plugging direction , which is purely possible in principle, since the discharge of the electrical conductors is perpendicular to the plane, namely in the opening 207, for example, a ribbon cable or individual wires are inserted, in the second housing part 200, for example, in DE 10 2004 054 203 A1 be contacted by means of insulation displacement contacts. The housing part 100 is In contrast, for example, arranged on a circuit board and the contact elements are contacted via corresponding conductor tracks on the circuit board. In principle, however, the housing part 100 could also be designed so that the electrical conductors are led away from the drawing plane, for example, as in the case of the housing part 200 perpendicular or parallel to the plane, ie parallel to the insertion direction.
Der Verriegelungsbügel 300 ist bevorzugt ein Kunststoffteil, welches eine gewisse Elastizität aufweist, welches leicht ist und welches darüber hinaus auch elektrisch isolierend ist. Der Vorteil der beschriebenen Ausbildung des Verriegelungsbügels 300 ist darin zu sehen, dass er als separates Teil ausgeführt ist. Dies ermöglicht nicht nur eine einfache Handhabung, er kann so auch leicht bei einer Beschädigung ausgetauscht und durch einen unbeschädigten Verriegelungsbügel 300 ersetzt werden. Darüber hinaus umgreift er das Gehäuseteil 200 großflächig, was eine sichere Verriegelung, auch Sekundärverriegelung, des zweiten Gehäuseteils 200 an dem ersten Gehäuseteil 100 sicherstellt. Durch die in den Innenseiten seiner Schenkel 301 , 302 ausgebildeten Nuten, die mit entsprechenden Vorsprüngen 210 an dem zweiten Gehäuseteil 200 zusammenwirken, ist nicht nur eine präzise und lagebestimmte Führung des Verriegelungsbügels an dem zweiten Gehäuseteil 200 und der Rastelemente an dem ersten Gehäuseteil 100 möglich, es wird hierdurch auch eine besonders stabile Verriegelung erzielt. The locking bracket 300 is preferably a plastic part, which has a certain elasticity, which is light and which is also electrically insulating beyond. The advantage of the described embodiment of the locking bracket 300 is the fact that it is designed as a separate part. This not only allows easy handling, it can also be easily replaced in case of damage and replaced by an undamaged locking bracket 300. In addition, it encompasses the housing part 200 over a large area, which ensures a secure locking, including secondary locking, of the second housing part 200 on the first housing part 100. By formed in the inner sides of its legs 301, 302 grooves, which cooperate with corresponding projections 210 on the second housing part 200, not only a precise and positionally determined guidance of the locking bracket on the second housing part 200 and the locking elements on the first housing part 100 is possible, It is thereby achieved a particularly stable locking.
