Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem Stecker für eine elektrische Steckverbindung nach der Gattung des Patentanspruchs 1.The invention relates to a plug for an electrical connector according to the preamble of claim 1.

Elektrische Steckverbindungen sind dafür vorgesehen, über ihre beiden Stecker (Buchsenteil und Steckteil) z.B. zwischen einer elektrischen Leitung und einer weiteren elektrischen Leitung oder zwischen einer elektrischen Leitung und einem elektrischen Aggregat eine wieder lösbare elektrische Verbindung herzustellen.Electrical plug connections are intended to be connected via their two plugs (socket part and plug-in part), e.g. to establish a re-releasable electrical connection between an electrical line and a further electrical line or between an electrical line and an electrical unit.

Eine bekannte Steckverbindung besteht aus einem metallischen Kontakt mit Crimp oder Lötstelle, metallischen Messern (Pins), zwei Steckergehäusen aus Kunststoff (Thermoplast) sowie Dichtungselementen (Elastomere) und zusätzlichen Sicherungselementen für die Kontakte, so genannten Sekundärverriegelungen. Der eine Stecker der Steckverbindung ist ein so genannter Kabelbaumstecker, der zusätzlich noch Sicherungselemente wie Sekundärverriegelungen besitzen kann. Der andere Stecker der Steckverbindung ist ein so genannter Kupplungsstecker, der aus mindestens drei Teilen, nämlich Steckergehäuse, Kontaktträgerunterteil und Sekundärverriegelungselement, besteht. Diese drei Teile bedeuten, dass drei Spritzwerkzeuge vorhanden sein müssen, um die Teile herzustellen, und dass die drei Teile zueinander zum Kupplungsstecker gefügt werden müssen.A known connector consists of a metallic contact with crimp or solder joint, metallic knives (pins), two connector housings made of plastic (Thermoplastic) as well as sealing elements (elastomers) and additional securing elements for the contacts, so-called secondary locks. One connector of the connector is a so-called harness connector, which may additionally have security elements such as secondary locks. The other plug of the connector is a so-called coupling plug, which consists of at least three parts, namely connector housing, contact carrier lower part and secondary locking element. These three parts mean that three injection tools must be present to make the parts, and that the three parts must be joined together to form the coupling plug.

Es wird auf die US 2002/0076992 A1 verwiesen, die alle Merkmale des Oberbegriffs offenbart.It will be on the US 2002/0076992 A1 referenced, which discloses all the features of the preamble.

Offenbarung der ErfindungDisclosure of the invention

Es ist die Aufgabe der Erfindung, bei einem Stecker der eingangs genannten Art die Teileanzahl weiter zu reduzieren.It is the object of the invention to further reduce the number of parts in a plug of the type mentioned.

Diese Aufgabe wird erfindungsgemäß gelöst durch einen Stecker mit den Merkmalen des Patentanspruchs 1.This object is achieved by a plug with the features of claim 1.

Der erfindungsgemäße Stecker umfasst nur noch zwei Kunststoffteile (z.B. Thermoplast), nämlich das Kontaktkammergehäuse und das Sekundärverriegelungselement, welches eine doppelte Funktion besitzt. Zum einen dient es als Sekundärverriegelung der im Stecker aufgenommenen elektrischen Kontakte (Messer oder Pins), und zum anderen bildet es einen Teil der Kammerwand (z.B. die vierte Fläche) der Kontaktkammer im Kontaktkammergehäuse aus. Dadurch ist es möglich, im Stecker das Kontaktkammergehäuse im Spritzgießverfahren einteilig herzustellen. In den Stecker ist vorzugsweise eine Innen- und/oder eine Außencodierung integriert. Aufgrund der zweiteiligen Konstruktion des erfindungsgemäßen Steckers wird das bisher erforderlich dritte Kunststoffteil eingespart, so dass Herstellung und Montage des dritten Kunststoffteils im Stecker entfallen.The plug according to the invention comprises only two plastic parts (for example thermoplastic), namely the contact chamber housing and the secondary locking element, which has a double function. On the one hand it serves as secondary locking of the electrical contacts (knives or pins) received in the plug, and on the other hand it forms a part of the chamber wall (for example the fourth face) of the contact chamber in the contact chamber housing. This makes it possible to produce the contact chamber housing in one piece in the injection molding process in the plug. In the plug an internal and / or external coding is preferably integrated. Due to the two-part construction of the plug according to the invention, the previously required third plastic part is saved, so that production and assembly of the third plastic part omitted in the plug.

Abschließend wird das Sekundärverriegelungselement 3 in seine Verriegelungsposition verschoben, wodurch die Verriegelungsvorsprünge 11 in den Kontaktkammern 14 Hinterschneidungen 25 (Fig. 5a) der Messer 15 in deren Einführrichtung hintergreifen und dadurch die Messer 15 in ihrer korrekt eingeführten Position verriegeln. Das Sekundärverriegelungselement 3 lässt sich nur dann in seine Verriegelungsposition verschieben, wenn sich alle Messer 15 in ihrer korrekt eingeführten Position befinden; anderenfalls muss die Position der Messer 15 überprüft werden.The coupling plug 2 is assembled as follows: First, the secondary locking element 3 is inserted into its preassembled position, and then the blades 15 are inserted into the contact chambers 14 through the openings of the sleeve bottom 13, ie from the back of the coupling plug 2. Finally, the secondary locking element 3 is moved to its locking position, whereby the locking projections 11 in the contact chambers 14 undercuts 25 (FIGS. Fig. 5a ) of the knife 15 engage behind in the insertion direction and thereby lock the knife 15 in its correctly inserted position. The secondary locking element 3 can only be moved to its locking position when all the blades 15 are in their correctly inserted position; otherwise, the position of the blades 15 must be checked.

Fig. 5a zeigt einen Längsschnitt durch die ineinander gesteckten Kupplungs- und Kabelbaumstecker 2, 4. Der Kabelbaumstecker 4 weist entsprechende Gegenkontakte 26 auf, in die die Messer 15 des Kupplungssteckers 2 eingreifen. Außen an der Steckhülse 6 ist noch eine Rastnase 27 zur Verrastung des Kupplungssteckers 2 mit dem Kabelbaumstecker 4 vorgesehen. Wie in Fig. 5b gezeigt, weist das Sekundärverriegelungselement 3 zwei nach vorne vorstehende Sperrvorsprünge 28 und das Abtastelement 5 des Kabelbaumsteckers 4 einen Abtastarm 29 auf. Nur wenn das Sekundärverriegelungselement 3 sich in seiner Verriegelungsposition befindet, kann der Abtastarm 29 zwischen die beiden Sperrvorsprünge 28 eingreifen und so die Steckverbindung zwischen Kupplungs- und Kabelbaumstecker 2, 4 ausgebildet werden. Fig. 5a shows a longitudinal section through the nested coupling and harness connector 2, 4. The harness connector 4 has corresponding mating contacts 26 , in which engage the blades 15 of the coupling plug 2. Outside of the socket 6 is still a locking lug 27 is provided for locking the coupling plug 2 with the harness connector 4. As in Fig. 5b 2, the secondary locking element 3 has two locking protrusions 28 protruding forwardly and the scanning element 5 of the wiring harness connector 4 has a scanning arm 29 . Only when the secondary locking element 3 is in its locking position, the Abtastarm 29 can engage between the two locking projections 28 and so the connector between the coupling and harness connector 2, 4 are formed.

Fign. 6a, 6b zeigen den Kupplungsstecker 2 mit zwei unterschiedlich ausgebildeten Außencodierungen 22, und Fign. 7a, 7b zeigen den Kupplungsstecker 2 mit zwei unterschiedlichen Innencodierungen 30. Diese Codierungen 22, 30 in Verbindung mit einer entsprechenden Gegencodierung (nicht gezeigt) des Kabelbaumsteckers 4 dienen dazu, ein Verwechseln zu verhindern, wenn in einer Anlage mehrere Stecker der gleichen Bauart eingesetzt werden. FIGS. 6a, 6b show the coupling plug 2 with two differently shaped external codes 22, and FIGS. 7a, 7b show the coupling plug 2 with two different inner codings 30. These codings 22, 30 in conjunction with a corresponding Gegencodierung (not shown) of the harness connector 4 are used to prevent confusion when multiple plugs of the same type are used in a system.
