Description

Die Erfindung betrifft einen Steckverbinder gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a connector according to the preamble of claim 1.

Üblicherweise wird bei einem solchen Steckverbinder der Steckkontakt mit dem Anschlußkontakt während der Montage verlötet. Dies gewährleistet zwar eine zuverlässige elektrische Verbindung zwischen den beiden Kontakten, erhöht aber auch die Herstellkosten. Es sind auch Steckverbinder bekannt, bei denen der Steckkontakt oder der Anschlußkontakt mit einer Steckbuchse versehen ist und das andere Kontaktteil mit einem Stift, der in die Steckbuchse eingesteckt werden kann. Dies ermöglicht allerdings nur eine Steckverbindung, wenn als Steckkontakt eine Buchse verwendet wird.Usually, in such a connector, the plug contact is soldered to the terminal contact during assembly. Although this ensures a reliable electrical connection between the two contacts, but also increases the production costs. There are also known connectors in which the plug contact or the terminal contact is provided with a socket and the other contact part with a pin which can be inserted into the socket. However, this only allows a plug connection when a socket is used as a plug contact.

Aus der DE 196 06 505 A1 ist ein Stecker mit den Merkmalen des Oberbegriffs des Anspruchs 1 bekannt. Der erste Isolierkörper ist hier der Grundkörper eines Diagnosesteckers, und der zweite Isolierkörper ist ein Kontaktmodul, das austauschbar am Diagnosestecker angebracht werden kann und die Kontakte enthält, die mit den Kontakten des auszulesenden Geräts in Verbindung gebracht werden. Wenn die Kontakte des Diagnosesteckers abgenutzt sind, wird das Kontaktmodul gegen ein neues ausgetauscht.From the DE 196 06 505 A1 a plug having the features of the preamble of claim 1 is known. Here, the first insulating body is the main body of a diagnostic connector, and the second insulating body is a contact module that can be interchangeably attached to the diagnostic connector and contains the contacts that are connected to the contacts of the device to be read. If the contacts of the diagnostic connector are worn out, the contact module is replaced with a new one.

Die Aufgabe der Erfindung besteht darin, einen Steckverbinder derart weiterzubilden, daß sich geringe Herstellkosten bei gleichzeitig weiterhin zuverlässiger elektrischer Verbindung zwischen den beiden Kontakten ergeben. Der Steckverbinder soll weiterhin eine Modulbauweise ermöglichen, so daß mit wenigen Bauteilen eine Vielzahl von Anwendungsfällen abgedeckt werden kann.The object of the invention is to develop a connector such that there are low production costs while still reliable electrical connection between the two contacts. The connector should continue to allow a modular design, so that with a few components a variety of applications can be covered.

Zu diesem Zweck ist der erfindungsgemäß ein Steckverbinder mit den Merkmalen des Anspruchs 1 vorgesehen. Die beiden Federlaschen ermöglichen durch ihre Elastizität, über lange Zeiträume eine gewünschte Kontaktkraft zwischen dem Steckkontakt und dem Anschlußkontakt aufrechtzuerhalten. Diese Kontaktkraft ist höher als bei der Verwendung von Buchse und Stift, da sich anstelle einer Flächenberührung, wie sie im Stand der Technik eintritt, eine linienförmige Berührung oder sogar Punktberührung einstellt. Die Stecklasche kann mit besonders geringem Aufwand dann ausgebildet werden, wenn es sich bei dem entsprechenden Kontakt um einen flachen Kontakt handelt, der beispielsweise aus einem Blech ausgestanzt wird, beispielsweise um eine Schneidklemme, die als Anschlußkontakt für ein an den Steckverbinder anzuschließendes Kabel dient.For this purpose, the invention provides a connector with the features of claim 1. The two spring tabs allow by their elasticity, over long periods of time to maintain a desired contact force between the plug contact and the terminal contact. This contact force is higher than with the use of socket and pin, since instead of a surface contact, as occurs in the prior art, adjusts a linear touch or even point contact. The tab can be formed with very little effort when it is at the corresponding contact to a flat contact, which is punched out of a sheet, for example, a cutting clamp, which serves as a terminal contact for a connector to be connected to the cable.

Vorzugsweise ist vorgesehen, daß der Isolierkörper mit mindestens einem Führungsstift versehen ist, der die korrekte Ausrichtung des Isolierkörpers gewährleistet, so daß eine spezielle Polarisierung von Abschluß- und Steckkontakten relativ zueinander zuverlässig beibehalten wird.It is preferably provided that the insulating body is provided with at least one guide pin, which ensures the correct orientation of the insulator, so that a specific polarization of termination and plug contacts relative to each other is reliably maintained.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß einer der Isolierkörper ein Gehäuse des Steckverbinders ist und der andere Isolierkörper ein Einsatzstück ist, das in dem Gehäuse aufgenommen ist. Bei dieser Gestaltung ergibt sich eine besonders kostengünstige Herstellung, da lediglich die beiden Isolierkörper mit den entsprechenden Kontakten bestückt werden müssen und abschließend der eine Isolierkörper in den anderen eingesetzt werden muß, wobei eine Rastverbindung verwendet werden kann, um den Isolierkörper im Gehäuse festzulegen. Beim Einschieben des Isolierkörpers werden die Steck- und die Anschlußkontakte ineinander eingesteckt, ohne daß weitere Schritte erforderlich sind. Bisher war eine solche Montage nicht möglich, da während der Montage die Anschluß- und die Steckkontakte miteinander verlötet werden mußten.According to a preferred embodiment of the invention it is provided that one of the insulating body is a housing of the connector and the other insulating body is an insert which is accommodated in the housing. In this design, a particularly cost-effective production, since only the two insulators must be equipped with the corresponding contacts and finally the one insulating body in the other must be used, with a locking connection can be used to set the insulating body in the housing. When inserting the insulating plug and the terminal contacts are plugged into each other, without further steps are required. So far, such an assembly was not possible because during assembly, the terminal and the plug contacts had to be soldered together.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments of the invention will become apparent from the dependent claims.

Die Erfindung wird nachfolgend anhand verschiedener Ausführungsformen beschrieben, die in den beigefügten Zeichnungen dargestellt sind. In diesen zeigen:

In den Figuren 1 bis 4 ist ein Steckverbinder gemäß einer ersten Ausführungsform gezeigt. Er weist einen ersten Isolierkörper 10 auf, der bei dieser Ausführungsform gleichzeitig das Gehäuse des Steckverbinders bildet. Der erste Isolierkörper weist mehrere Aufnahmeschlitze 12 auf, in die jeweils ein Anschlußkontakt 14 eingesetzt ist. Unter Anschlußkontakt wird hier ein Kontakt verstanden, der dazu vorgesehen ist, an beispielsweise einen Leiter eines Kabels angeschlossen zu werden. Bei der gezeigten Ausführungsform sind die Anschlußkontakte 14 an ihrem Anschlußende als Schneidklemmen 16 (siehe Fig. 2) ausgebildet, in die der Leiter des anzuschließenden Kabels eingepreßt werden kann, so daß die Schneidklemmen die Isolierung des Leiters durchschneiden und automatisch die Kontaktierung erfolgt. An ihrem von den Schneidklemmen 16 abgewandten Ende sind die Kontakte mit jeweils einer Stecklasche 18 versehen, deren Funktion später erläutert wird. Zwischen der Schneidklemme 16 und der Stecklasche 18 ist jeder Anschlußkontakt mit einer Verriegelungslasche 20 versehen, so daß der Anschlußkontakt, wenn er in den Aufnahmeschlitz 12 in der Richtung des Pfeils P von Fig. 2 eingeschoben wird, unlösbar einrastet.In the FIGS. 1 to 4 a connector according to a first embodiment is shown. It has a first insulating body 10, which simultaneously forms the housing of the connector in this embodiment. The first insulating body has a plurality of receiving slots 12, in each of which a terminal contact 14 is inserted. By terminal contact is here understood a contact which is intended to be connected to, for example, a conductor of a cable. In the embodiment shown, the terminal contacts 14 at its terminal end as insulation displacement terminals 16 (see Fig. 2 ), in which the conductor of the cable to be connected can be pressed, so that the insulation displacement cut through the insulation of the conductor and the contacting takes place automatically. At their end facing away from the insulation displacement terminals 16, the contacts are each provided with a tab 18 whose function will be explained later. Between the insulation displacement terminal 16 and the insertion tab 18, each terminal contact is provided with a locking tab 20 so that the terminal contact when in the receiving slot 12 in the direction of the arrow P of Fig. 2 is inserted, indissoluble locks.

Der erste Isolierkörper 10 ist so ausgebildet, daß eine Aufnahme 22 gebildet ist, welche die Stecklaschen 18 der Anschlußkontakte 14 umgibt. In die Aufnahme 22 kann ein zweiter Isolierkörper 24 eingesetzt werden, der mit Steckkontakten 26 (siehe auch Fig. 3) versehen ist. Unter einem Steckkontakt wird hier ein Kontakt verstanden, der dafür vorgesehen ist, mit einem Kontakt eines komplementären Steckverbinders in Eingriff gebracht zu werden. Es kann sich dabei beispielsweise um einen Buchsenkontakt oder einen Stiftkontakt handeln.The first insulating body 10 is formed so that a receptacle 22 is formed, which surrounds the insertion tabs 18 of the terminal contacts 14. In the receptacle 22, a second insulating body 24 are used, which with plug contacts 26 (see also Fig. 3 ) is provided. A plug contact is here understood as a contact which is intended to be brought into engagement with a contact of a complementary plug connector. This may be, for example, a socket contact or a pin contact.

Der zweite Isolierkörper 24 ist mit mehreren Aufnahmebohrungen 28 versehen, in welche die Steckkontakte 26 so eingesteckt werden, daß sie darin einrasten. Jeder Steckkontakt weist bei der gezeigten Ausführungsform einen Buchsenabschnitt 30 auf, in den ein Stiftkontakt eines komplementären Steckverbinders eingesteckt werden kann, sowie zwei Federlaschen 32, die einander durch einen Schlitz getrennt gegenüber liegen und jeweils in zwei Federsegmente unterteilt sind.The second insulating body 24 is provided with a plurality of receiving holes 28, in which the plug contacts 26 are inserted so that they engage therein. Each plug contact, in the embodiment shown, has a socket section 30 into which a pin contact of a complementary plug connector can be inserted, and two spring tabs 32 which are separated from one another by a slot and are each subdivided into two spring segments.

Am zweiten Isolierkörper 24 sind mehrere Rastnasen 34 vorgesehen, von denen in Fig. 3 nur eine einzige zu sehen ist. Am ersten Isolierkörper 10 sind komplementäre Gestaltungen vorgesehen, an denen die Rastnasen einrasten können. Am ersten Isolierkörper 10 sind außerdem mehrere Führungsstifte 36 ausgebildet, die in komplementäre Führungsöffnungen 38 am zweiten Isolierkörper 24 eingreifen können.On the second insulating body 24 a plurality of locking lugs 34 are provided, of which in Fig. 3 only one can be seen. At the first insulating body 10 complementary configurations are provided, where the locking lugs can engage. On the first insulating body 10, a plurality of guide pins 36 are also formed, which can engage in complementary guide openings 38 on the second insulating body 24.

Der Steckverbinder wird in der folgenden Weise montiert: Zunächst werden die Anschlußkontakte 14 in die Aufnahmeschlitze 12 des ersten Isolierkörpers und die Steckkontakte 26 in die Aufnahmebohrungen 28 des zweiten Isolierkörpers 24 eingeschoben, so daß sie dort jeweils einrasten. Dann wird der zweite Isolierkörper 24 in den ersten Isolierkörper 10 eingeschoben, wobei die Führungsstifte 36 zusammen mit den Führungsöffnungen 38 die korrekte Ausrichtung der beiden Isolierkörper zueinander gewährleisten, so daß eine spezielle Codierung erzielt wird. Beim Einschieben des zweiten Isolierkörpers 24 in den ersten Isolierkörper 10 werden die Federlaschen 32 der Steckkontakte 26 auf die Stecklaschen 18 der Anschlußkontakte 14 aufgeschoben, so daß sich eine elektrisch leitende Verbindung zwischen den Anschlußkontakten 14 und den Steckkontakten 26 ergibt. Wenn der zweite Isolierkörper 24 vollständig in den ersten Isolierkörper 10 eingeschoben ist, schnappen die Rastnasen 34 am ersten Isolierkörper 10 ein, so daß die beiden Isolierkörper fest miteinander verbunden sind. Dieser Zustand ist in Fig. 4 zu sehen; die Federlaschen 32 sind vollständig auf die Stecklaschen 18 der Anschlußkontakte aufgeschoben. Der Steckverbinder ist dann fertig montiert.The connector is mounted in the following manner: First, the terminal contacts 14 are inserted into the receiving slots 12 of the first insulating body and the plug contacts 26 in the receiving bores 28 of the second insulating body 24, so that they respectively engage there. Then, the second insulating body 24 is inserted into the first insulating body 10, wherein the guide pins 36 together with the guide openings 38 ensure the correct alignment of the two insulator to each other, so that a special coding is achieved. When inserting the second insulating body 24 in the first insulating 10, the spring tabs 32 of the plug contacts 26 are pushed onto the tabs 18 of the terminal contacts 14, so that there is an electrically conductive connection between the terminal contacts 14 and the plug contacts 26. When the second insulating body 24 is fully inserted into the first insulating body 10, snap the locking lugs 34 on the first insulating body 10, so that the two insulating bodies are firmly connected. This condition is in Fig. 4 to see; the spring tabs 32 are completely pushed onto the tabs 18 of the terminal contacts. The connector is then fully assembled.

Abgesehen von der besonders einfachen Montage, die lediglich aus mehreren Steckvorgängen besteht, die noch dazu in derselben Richtung erfolgen, ermöglicht der beschriebene Aufbau eine besonders variable Herstellung, da verschiedene Isolierkörper mit verschiedenen Kontakten nach Art eines Modulsystems kombiniert werden können.Apart from the particularly simple installation, which consists only of several plug-in operations, which still take place in the same direction allows the structure described a particularly variable production, since different insulator can be combined with different contacts in the manner of a modular system.

Alternativ zur Befestigung der Anschluß- und der Steckkontakte durch Einrasten kann auch vorgesehen sein, daß die Kontakte entweder nur lose in die Aufnahmeschlitze des ersten Isolierkörpers und die Aufnahmebohrungen des zweiten Isolierkörpers eingesetzt sind oder dort mit einer Preßpassung eingeschoben werden. Die endgültige Festlegung erfolgt erst, wenn der zweite Isolierkörper in den ersten Isolierkörper eingesteckt ist.Alternatively to the attachment of the terminal and the plug contacts by snap can also be provided that the contacts are either only loosely inserted into the receiving slots of the first insulator and the receiving holes of the second insulator or inserted there with a press fit. The final determination takes place only when the second insulating body is inserted into the first insulating body.

In den Figuren 5 und 6 ist ein Steckverbinder gemäß einer zweiten Ausführungsform gezeigt. Die zweite Ausführungsform ähnelt der ersten Ausführungsform hinsichtlich der Ausgestaltung der beiden Isolierkörper 10, 24. Der Unterschied zur ersten Ausführungsform liegt in der Ausgestaltung der Steckverbindung zwischen den Schneidklemmen 16 und den Steckkontakten 26.In the Figures 5 and 6 a connector according to a second embodiment is shown. The second embodiment is similar to the first embodiment in terms of the design of the two insulating body 10, 24. The difference from the first embodiment lies in the configuration of the connector between the insulation displacement terminals 16 and the plug contacts 26th

Bei der zweiten Ausführungsform ist jede Schneidklemme mit zwei nebeneinanderliegenden Federlaschen 32' versehen, die zusammen einen allgemein rechteckigen Körperabschnitt und einen abgerundeten Kopfabschnitt bilden. Der die beiden Federlaschen 32' voneinander trennende Schlitz endet in einer kreisrunden Ausnehmung, die zum einen die gewünschte Elastizität der Federlaschen 32' relativ zueinander ermöglicht und zum anderen eine Kerbwirkung am Ende des Schlitzes vermeidet.In the second embodiment, each insulation displacement clamp is provided with two adjacent spring tabs 32 'which together form a generally rectangular body portion and a rounded head portion. The two spring tabs 32 'separating slot ends in a circular recess, on the one hand allows the desired elasticity of the spring tabs 32 'relative to each other and on the other avoids a notch effect at the end of the slot.

Die Steckkontakte sind mit einer Steckbuchse 18' mit kreisförmigem Querschnitt zur Aufnahme des von den beiden Federlaschen 32' gebildeten Kopfabschnittes versehen.The plug contacts are provided with a socket 18 'with a circular cross-section for receiving the head portion formed by the two spring tabs 32'.

Wenn der mit den Steckkontakten 26 versehene zweite Isolierkörper 24 in die Aufnahme 22 im ersten Isolierkörper eingeschoben wird, wird der abgerundete Kopfabschnitt der Federlaschen 32' in die Steckbuchse 18' des entsprechenden Steckkontakts 26 eingeschoben. Dabei werden der Kopfabschnitt und dadurch auch der Körperabschnitt elastisch zusammengedrückt, und es ergibt sich eine sichere Kontaktierung zwischen den Schneidklemmen und den Steckkontakten. Im Gegensatz zur ersten Ausführungsform, bei der die Stecklasche des Steckkontakts zwischen die Federlaschen gesteckt wurde, greift also der Steckkontakt auf der Außenseite der Federlaschen an.When the second insulating body 24 provided with the plug-in contacts 26 is inserted into the receptacle 22 in the first insulating body, the rounded head portion of the spring tabs 32 'is inserted into the socket 18' of the corresponding plug-in contact 26. In this case, the head portion and thereby also the body portion are elastically compressed, and there is a secure contact between the insulation displacement terminals and the plug contacts. In contrast to the first embodiment, in which the plug-in tab of the plug contact was inserted between the spring tabs, so the plug contact engages on the outside of the spring tabs.

Wenn der zweite Isolierkörper 24 vollständig in die Aufnahme 22 im ersten Isolierkörper eingeschoben ist (siehe Figur 11), liegt die Stirnseite der Steckbuchse 18' am Übergang zwischen dem Kopfabschnitt und dem Körperabschnitt der Federlaschen 32' an.When the second insulating body 24 is fully inserted into the receptacle 22 in the first insulating body (see Figure 11), the end face of the socket 18 'is located at the transition between the head portion and the body portion of the spring tabs 32'.
