Description

Die vorliegende Erfindung betrifft eine Steckverbindungseinrichtung für Schwachstromanlagen insbesondere der Tele- und Datenkommunikation, mit einer mehrpoligen Steckdose, deren Kontaktstifte in vorbestimmtem Grundmodul angeordnet sind, sowie mit einem, mit der Steckdose zusammenwirkenden Stecker, wobei zwischen Steckdose und Stecker Kodierungsmittel vorgesehen sind, die bei Nichtübereinstimmung ein Kontakte verbindendes Zusammenstecken von Stecker und Steckdose verhindern.The present invention relates to a connector for low-voltage systems, in particular for telecommunications and data communication, with a multipole socket, the contact pins of which are arranged in a predetermined basic module, and with a plug interacting with the socket, coding means being provided between the socket and the plug, which mismatch Prevent the plug and socket from being plugged together.

Bei Schwachstromanlagen insbesondere der Tele- und Datenkommunikation nimmt das Problem zu, die unterschiedlichsten Anschluss-Systeme, wie beispielsweise Telefonie- oder OnLine-Systeme, EDV-Systeme u. dgl. miteinander steckbar zu verbinden, ohne dass Falschverbindungen zustande kommen.In the case of low-voltage systems, in particular telecommunications and data communication, the problem is increasing, the most varied Connection systems, such as telephony or online systems, EDP systems and. Like. To connect pluggable with each other without false connections.

Es sind deshalb Kodierungsmittel üblich, die bei Nichtübereinstimmung ein Kontakte verbindendes Zusammenstecken von Stecker und Steckdose verhindern.Coding means are therefore common which prevent the plug and socket from being plugged together in the event of a mismatch.

Solche Anordnungen sind etwa durch die DE-1-2646063 bekannt geworden, wo herausbrechbare Kodiernocken an der Steckdose mit Ausnehmungen am Stecker resp. Kodierzapfen an der Steckdose mit Drehscheiben am Stecker zusammenwirken.Such arrangements are known for example from DE-1-2646063, where break-out coding cams on the socket with recesses on the plug, respectively. Interact the coding pin on the socket with the turntables on the plug.

Durch diese Massnahmen ist es nun zwar möglich, bei Nichtübereinstimmung der Kodierungsmittel eine Steckverbindung zu verhindern, es hat sich aber gezeigt, dass Steckverbindungseinrichtungen dieser Art weder konstruktiv noch im Hinblick auf eine ausreichende Anzahl und leicht vorzunehmende Kodierung genügen.Through these measures, it is now possible to prevent a plug connection if the coding means do not match, but it has been shown that plug connection devices of this type are neither sufficient in terms of design nor in terms of a sufficient number and coding that is easy to carry out.

Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Steckverbindungseinrichtung der vorgenannten Art unter Vermeidung der Nachteile des bekannten Standes der Technik so auszugestalten, dass sich praktisch unbeschränkte Kodierungsmöglichkeiten ergeben, die sich einfach und sicher herstellen lassen, wobei alle Bauteile den heutigen Anforderungen an eine Massenfabrikation erfüllen.It is therefore an object of the present invention to design a plug connection device of the aforementioned type while avoiding the disadvantages of the known prior art in such a way that there are practically unlimited coding possibilities which are simple and safe Have it manufactured, with all components meeting today's requirements for mass production.

Dies wird erfindungsgemäss dadurch erreicht, dass die Kodierungsmittel einen hülsenförmigen Einsatz umfassen zur kodierenden Anpassung des geometrischen Querschnittes der Steckeröffnung der Steckdose an den Querschnitt des Einsteckteiles des zu verwendenden Steckers.This is achieved according to the invention in that the coding means comprise a sleeve-shaped insert for the coding adaptation of the geometric cross section of the plug opening of the socket to the cross section of the plug-in part of the plug to be used.

Wie ohne weiteres erkenntlich, gestalten solche hülsenförmigen Bauteile eine Anpassung der Steckeröffnung der Steckdose an jeden nur denkbaren geometrischen Querschnitt des Einsteckteiles des zu verwendenden Steckers, womit sich praktisch unbeschränkte Kodierungsmöglichkeiten ergeben, bei einfachsten Bauteilen und einfachster Handhabung.As can easily be seen, such sleeve-shaped components adapt the plug opening of the socket to any conceivable geometric cross section of the plug-in part of the plug to be used, which results in practically unlimited coding possibilities, with the simplest components and simple handling.

Hierbei kann eine konstruktive Vereinfachung darin gesehen werden, wenn der hülsenförmige Einsatz quer- oder längsgeteilt ist.A design simplification can be seen here if the sleeve-shaped insert is divided transversely or lengthwise.

Die Kodierungsmöglichkeiten können mit gleichen Kodierungsmitteln zudem verdoppelt werden, wenn der hülsenförmige Einsatz umkehrbar in die Steckeröffnung der Steckdose einsetzbar ist.The coding options can also be doubled with the same coding means if the sleeve-shaped Insert can be inserted reversibly into the plug opening of the socket.

Weitere Kodierungsmöglichkeiten sind dann gegeben, wenn in Steckrichtung verlaufende innenseitige Nuten am hülsenförmigen Einsatz resp. aussenseitige Nuten am Einsteckteil des Steckers der Aufnahme von Kodierungs-Zwischenprofilen dienen.Further coding options are available if the inside grooves running in the direction of insertion on the sleeve-shaped insert resp. Grooves on the outside of the plug-in part of the plug serve to accommodate intermediate coding profiles.

Eine weitere vorteilhafte Ausgestaltung bezüglich einer rationellen und sicheren Montage besteht ferner dann, wenn die Steckdose elastisch gegeneinander drückbare parallele Wandungsteile mit aussenseitigen Nocken zum Uebergreifen einer Montageplatte aufweist, wobei der hülsenförmige Einsatz in eingesetztem Zustand als Verriegelungsvorrichtung wirksam ist. Zudem ist es hier vorteilhaft, wenn die Steckdose bodenseitig einen Deckel umfasst, vorzugsweise mit abragenden Rippen zum lötfreien Verbinden durch Eindrücken der Aderenden in Schneiden der Kontaktstifte.A further advantageous embodiment with regard to efficient and safe installation also exists when the socket has parallel wall parts with elastic cams that can be pressed against one another to overlap a mounting plate, the sleeve-shaped insert being effective as a locking device in the inserted state. In addition, it is advantageous here if the socket comprises a cover on the bottom, preferably with protruding ribs for solderless connection by pressing in the wire ends in the cutting edges of the contact pins.

For example, embodiments of the subject matter of the invention are explained in more detail below with reference to the drawing. Show it:
Fig. 1
in a diagram-like representation a connector device with socket, sleeve-shaped insert and plug, according to the invention;
Fig. 2
in a diagram-like representation, the socket with sleeve-shaped insert according to Figure 1 on a mounting plate.
Fig. 3

4 and 5
A diagram-like representation of an embodiment variant of the plug connection device according to FIG. 1.

Die erfindungsgemässe Steckverbindungseinrichtung gemäss Fig. 1 umfasst eine mehrpolige Steckdose 1, deren Kontaktstifte 2 in vorbestimmtem Grundmodul angeordnet sind, sowie eine, mit der Steckdose zusammenwirkenden Stecker 3, wobei zwischen Steckdose und Stecker Kodierungsmittel vorgesehen sind, die bei Nichtübereinstimmung ein Kontakte verbindendes Zusammenstecken von Stecker und Steckdose verhindern.1 comprises a multi-pole socket 1, the contact pins 2 of which are arranged in a predetermined basic module, and a plug 3 which interacts with the socket, coding means being provided between the socket and the plug which, when the plug does not match, plug together the plug and prevent the socket.

Erfindungsgemäss umfassen hier die Kodierungsmittel einen, den geometrischen Querschnitt der Steckeröffnung 4 der Steckdose 1 entsprechend dem Querschnitt des Einsteckteiles 5 des zu verwendenden Steckers 3 ändernden hülsenförmigen Einsatz 6. Die Kodierung besteht hier in der Schulter 16 resp. der Nut 166 innenseitig des hülsenförmigen Einsatzes 6, entsprechend dem Querschnitt des Einsteckteiles 5 des Steckers 3.According to the invention, the coding means comprise a sleeve-shaped insert 6 which changes the geometric cross section of the plug opening 4 of the socket 1 in accordance with the cross section of the plug-in part 5 of the plug 3 to be used. The coding here is in the shoulder 16 or. the groove 166 on the inside of the sleeve-shaped insert 6, corresponding to the cross section of the plug-in part 5 of the plug 3.

Für eine andere Kodierung zur Verwendung eines nicht näher gezeigten Steckers kann beispielsweise die Hülse 6 umgedreht eingesetzt werden.For another coding for the use of a plug, not shown in detail, the sleeve 6 can, for example, be used upside down.

Eine andere Kodierung weist die Anordnung gemäss Fig. 4 auf in Uebereinstimmung mit der Querschnittsform des Einsteckteiles 5′ des Steckers 3′ in Fig. 5. Zudem sind hier weitere Kodierungsmöglichkeiten angedeutet, indem die in Steckrichtung verlaufende innenseitige Nute 166 am hülsenförmigen Einsatz 6′ resp. aussenseitige Nute 13 am Einsteckteil 5 des Steckers 3′ der Aufnahme von Kodierungs-Zwischenprofilen 7 dienen, wie das durch strichpunktierte Linien angedeutet ist.Another coding has the arrangement according to FIG. 4 in accordance with the cross-sectional shape of the plug-in part 5 'of the plug 3' in Fig. 5. In addition, further coding possibilities are indicated here by the inside groove 166 running in the plug-in direction on the sleeve-shaped insert 6 'or . outside groove 13 on the insertion part 5 of the plug 3 'serve to accommodate intermediate coding profiles 7, as indicated by dash-dotted lines.

Wie Fig. 1 und 2 mehr im Einzelnen zeigen, weist ferner die Steckdose 1 elastisch gegeneinander drückbare parallele Wandungsteile 11 mit aussenseitigen Nocken 12 zum Uebergreifen einer Montageplatte 21 auf, wobei der hülsenförmige Einsatz 6 in eingesetztem Zustand als Verriegelungsvorrichtung wirksam ist.As shown in FIGS. 1 and 2 in more detail, the socket 1 also has parallel parallel elastically pushable Wall parts 11 with cams 12 on the outside for gripping over a mounting plate 21, the sleeve-shaped insert 6 being effective as a locking device in the inserted state.

Dies erlaubt eine schnelle und sichere Montage solcher Steckdosen an Grundplatten, Gehäusen und dgl., die nur einen Ausschnitt entsprechend der äusseren Abmessungen der Steckdose aufweisen müssen.This allows a quick and safe installation of such sockets on base plates, housings and the like, which only have to have a cutout corresponding to the outer dimensions of the socket.

Für eine lötfreie Verdrahtung der Steckdose ist es gemäss Fig. 3 zudem von Vorteil, wenn die Steckdose 1 bodenseitig einen Deckel 20 umfasst, vorzugsweise mit abragenden Rippen (nicht gezeigt) zum lötfreien Verbinden durch Eindrücken der Aderenden in Schneiden der Kontaktstifte (nicht gezeigt).For solderless wiring of the socket, it is also advantageous according to FIG. 3 if the socket 1 comprises a cover 20 on the bottom, preferably with protruding ribs (not shown) for solderless connection by pressing in the wire ends in the cutting edges of the contact pins (not shown).

Aus dem Vorbeschriebenen ergibt sich zunächst, dass die verwendeten Kodierungsmittel in Form von Hülsen und gegebenenfalls Kodierungs-Zwischenprofilen eine Anpassung der Steckeröffnung der Steckdose an jeden nur denkbaren geometrischen Querschnitt des Einsteckteiles des zu verwendenden Steckers gestatten, womit praktisch unbeschränkt viele Kodierungsmöglichkeiten möglich sind. Dabei erlauben die getroffenen Massnahmen eine robuste Konzeption einer solchen Steckverbindungseinrichtung und deren überaus leichte und sichere Handhabung sowohl in bezug auf eine Kodierung als auch in bezug auf ein Einstecken bzw. Herausziehen des Steckers.From the above, it first emerges that the coding means used in the form of sleeves and, if appropriate, coding intermediate profiles allow the plug opening of the socket to be adapted to any conceivable geometric cross section of the plug-in part of the plug to be used, with which practically unlimited coding possibilities are possible. The measures taken allow a robust concept such a connector device and its extremely easy and safe handling both in terms of coding and in terms of inserting or removing the plug.

Hierbei sind im Rahmen der Erfindung natürlich eine Reihe von Modifikationen denkbar. So lässt sich der hülsenförmige Einsatz auch quer- oder längsgeteilt gestalten.A number of modifications are of course conceivable within the scope of the invention. In this way, the sleeve-shaped insert can also be designed to be cross-wise or lengthways.
