Description

Die Erfindung betrifft ein Hausgeräte-Steckkontaktsystem zur Versorgung elektrischer Betriebsmittel in Hausgeräten, nach dem Oberbegriff des Anspruchs 1. Sie betrifft des weiteren eine in Anpassung an ein solches Steckkontaktsystem ausgeführte Platine sowie ein mit derartigen Platinen ausgestattetes Hausgerät.The invention relates to a domestic appliance plug contact system for supplying electrical equipment in domestic appliances, according to the preamble of claim 1. It further relates to a running in adaptation to such a plug contact circuit board and a household appliance equipped with such boards.

Elektrische Steckverbindungen der verschiedensten Ausführungen und Einsatzzwecke werden seit langem mit Kodiermitteln zur verwechslungssicheren Zuordnung der Stecker zu den Buchsen, Steckdosen oder Adaptern und häufig auch mit Rastmitteln zur zuverlässigen Fixierung einmal hergestellter Steckverbindungen versehen. Bereits eine bestimmte Anordnung von Kontaktflächen oder -stiften der Verbindungskomponenten stellt eine solche Kodierung dar - vielfach sind aber alternativ oder zusätzlich hierzu spezielle Aus- oder Anformungen an der Hülle der Verbinder als Kodiermittel vorgesehen. Auch Rastmittel werden einerseits durch geeignete Formgebung und/oder Stellung von Kontaktflächen bzw. -stiften und andererseits durch eine geeignete Ausbildung der Hülle bzw. des Gehäuses der Verbinder geschaffen.Electrical connectors of various designs and applications have long been provided with coding for confusion assignment of the plug to the sockets, sockets or adapters and often with locking means for reliable fixation once made connectors. Already a specific arrangement of contact surfaces or pins of the connection components represents such coding - but are often alternatively or additionally provided special Ausaus or formations on the shell of the connector as coding. Also locking means are created on the one hand by suitable shaping and / or position of contact surfaces or pins and on the other hand by a suitable design of the shell or the housing of the connector.

Zum elektrischen Anschluss von auf Platinen angeordneten elektrischen Betriebsmitteln von Hausgeräten dienen Steckverbindersysteme gemäß verschiedenen Firmenstandards, etwa bei·der Anmelderin gemäß den Werksnormen "RAST2,5" oder "RAST5". Mit diesen Werksnormen werden Vorschriften zur Ausführung von Steckern und sogenannten Wannen (entsprechend Buchsenteilen) bezüglich der Außenabmessungen und der Lage und Größe der elektrischen Kontakte, aber auch der Lage und Größe von an den Gehäusen vorgesehenen Kodiermitteln, gegeben. An die Stelle der erwähnten Wannen, die üblicherweise auf die Oberfläche einer Platine aufgesetzt werden, können hierbei sogenannte Kodierrahmen treten, die auf eine Platinenkante aufsetzbar sind. Auch für diese ist dann selbstverständlich die Anordnung und Größe der Kontaktflächen wie auch der Kodiermittel genormt.For the electrical connection of printed circuit boards arranged on electrical equipment of household appliances connector systems serve according to various company standards, for example the applicant according to the factory standards "RAST2,5" or "RAST5". These factory standards are given regulations for the execution of plugs and so-called tubs (corresponding to female parts) with respect to the outer dimensions and the position and size of the electrical contacts, but also the location and size of provided on the housings coding. In place of the mentioned trays, which are usually placed on the surface of a board, in this case so-called Kodierrahmen occur, which can be placed on a board edge. For this, of course, then the arrangement and size of the contact surfaces as well as the coding means is standardized.

In den Wannen bzw. Kodierrahmen sind jeweils auch (platinenseitige) Rastmittel vorgesehen, die zu steckerseitigen Rastmitteln korrespondieren und mit diesen zusammen für einen zuverlässigen Halt der Steckverbindungen sorgen. Die erwähnten Werksnormen der Anmelderin sehen beispielsweise für die Wannen nach RAST2,5 eine Innenverrastung (mit einer Ausnehmung auf Seiten der Wanne) oder Außenverrastung (mit einer an einem federnden Bügel angebrachten Rastnase auf Seiten der Wanne) vor. Auch ein Kodierrahmen gemäß RAST5 mit Außenverrastung hat eine Ausnehmung zum Eingriff einer Rastnase vor, die an einen biegeelastischen Fortsatz des dazu passenden Steckers angeformt ist.In the tubs or Kodierrahmen each (platinum-side) locking means are provided which correspond to plug-side locking means and together with these ensure a reliable hold of the connectors. For example, the Applicant's mentioned factory standards provide an internal latching (with a recess on the side of the tub) for the RAST2.5 tubs or external latching (with a latching tab on the side of the tub attached to a resilient clip). Also a coding frame according to RAST5 with external latching has a recess for engagement of a latching nose, which is integrally formed on a flexurally elastic extension of the matching plug.

Es ist auch möglich und bekannt, in die Kante einer Platine gemäß einem vorgegebenen Raster Kodierschlitze mit unterschiedlicher Länge und/oder Breite einzuarbeiten, auf die dann entsprechend ausgeführte Stecker passen. Bekannte Stecker der entsprechenden Bauart weisen einen innenliegenden federnden Fortsatz mit angeformter Rastnase auf, der beim Aufsetzen des Steckers auf die Platinenkante über die Platinenoberfläche gleitet, bis er in einer dort als platinenseitiges Rastmittel angebrachten Öffnung (Bohrung) einrasten kann. Nach dem Einrasten hält dieser Stecker sicher auf der Platinenkante, ohne dass dort ein Gegenstück in Art einer Wanne oder eines Kodierrahmens angebracht wäre.It is also possible and known to incorporate in the edge of a board according to a predetermined grid coding slots with different length and / or width, then fit into the appropriately designed connector. Known plug of the corresponding type have an internal resilient extension with molded locking lug, which slides when placing the plug on the board edge over the board surface until it can engage in a there attached as a platinum-side locking means opening (hole). After snapping this plug securely holds on the Platinenkante, without that there would be a counterpart in the manner of a pan or Kodierrahmens attached.

Die Druckschrift EP 0 262 432 A1 offenbart eine elektrische Steckverbindungsanordnung für Leiterplatten bestehend aus einem die Leiterplatte überdeckendes Anschluss steckgehäuse und einen Litzenstecker, wobei das Anschlusssteckgehäuse mit dem Litzenstecker korrespondierende Kodiernuten aufweist.The publication EP 0 262 432 A1 discloses an electrical connector assembly for printed circuit boards consisting of a circuit board covering the connector housing and a stranded connector, wherein the connector housing having the Litzenstecker corresponding coding grooves.

Die Druckschrift US 6,086,403A offenbart einen elektrischen Verbinder mit einem weiblichen Abschnitt, einer Vielzahl von elektrischen Kontakten, einem männlichen Abschnitt und Verbindungsmitteln, die an dem weiblichen und männlichen Teil angeordnet sind.The publication US 6,086,403A discloses an electrical connector having a female portion, a plurality of electrical contacts, a male portion, and connecting means disposed on the female and male portions.

Zuletzt offenbart die Druckschrift US 4,695,112 A einen elektrischen Steckverbinder, der im Kantenbereich auf eine eine Schlitzkodierung aufweisende Platine aufschiebbar ist.Lastly, the document discloses US 4,695,112 A an electrical connector which is pushed in the edge region on a slot encoding a circuit board.

Die erwähnten bekannten Lösungen sind insofern für den Hausgerätehersteller problematisch, als es sich bei den erwähnten Steckern um Zulieferteile verschiedener Hersteller handelt und die bekannten Steckkontaktsysteme bereits beim Entwurf einer Platine eine Festlegung auf einen Steckertyp eines Herstellers erfordern. Hierdurch wird eine vom Finalproduzenten nicht gewünschte Abhängigkeit vom Zulieferer (dem Steckerhersteller) erzeugt.The mentioned known solutions are problematic for the home appliance manufacturer, as it is in the aforementioned connectors to vendor parts of different manufacturers and the known plug contact systems already require the design of a board a commitment to a plug type manufacturer. This creates a dependency on the supplier (the connector manufacturer) that is not desired by the final producer.

Der Erfindung liegt daher die Aufgabe der Bereitstellung eines verbesserten Steckkontaktsystems zugrunde, welches die Abhängigkeit des Geräteherstellers von speziellen Zulieferern verringert.The invention is therefore based on the object of providing an improved plug-in contact system, which reduces the dependency of the device manufacturer of special suppliers.

Diese Aufgabe wird durch ein Steckkontaktsystem mit den Merkmalen der Ansprüche 1 und 4 bzw. eine Platine mit den Merkmalen des Anspruchs 10 gelöst.This object is achieved by a plug-in contact system having the features of claims 1 and 4 or a circuit board having the features of claim 10.

Die Erfindung schließt den wesentlichen Gedanken einer Kombination mindestens zweier bekannter platinenseitiger Verrastungslösungen oder Kodieranordnungen - oder beider-ein. Hierdurch werden mindestens die zu den miteinander kombinierten platinenseitigen Rast- und/oder Kodiermitteln korrespondierenden Steckertypen zweier Hersteller für den Anschluss der Platine einsetzbar, und die Abhängigkeit von einem Steckerhersteller wird beseitigt.The invention includes the essential idea of a combination of at least two known platinum-side latching solutions or coding arrangements - or both. As a result, at least the plug types of two manufacturers corresponding to the combined board-side latching and / or coding means can be used for connecting the board, and the dependence on a plug manufacturer is eliminated.

Grundsätzlich sind auch mehr als zwei Verrastungs- bzw. Kodierungslösungen kombinierbar, dies ist aber für die derzeit bekannten Steckkontaktanordnungen wenig sinnvoll. Bei dem aus derzeitiger Sicht bevorzugten Steckkontaktsystem handelt es sich also um eines mit einem ersten Stecker mit an der Außenoberfläche angeordneten steckerseitigen ersten Kodier und/oder Rastmitteln, einem zweiten Stecker mit im Inneren angeordneten steckerseitigen zweiten Kodier- und/oder Rastmitteln, einem auf eine Platinenkante aufsetzbaren Kodierrahmen mit innenliegenden, zu den an der Außenoberfläche des ersten Steckers angeordneten ersten Kodiermitteln korrespondierenden ersten platinenseitigen Kodiermitteln und an der Außenoberfläche angeordneten ersten platinenseitigen Rastmitteln zum Zusammenwirken mit den ersten Rastmitteln des ersten Steckers und an der Platinenkante, auf die der Kodierrahmen aufsetzbar ist, angeordneten platinenseitigen zweiten Kodiermitteln zum Zusammenwirken mit den an der Innenoberfläche des zweiten Steckers angeordneten zweiten Kodiermitteln und in der Platine vorgesehenen zweiten platinenseitigen Rastmitteln zum Zusammenwirken mit den zweiten Rastmitteln des zweiten Steckers.In principle, more than two Verrastungs- or coding solutions can be combined, but this makes little sense for the currently known plug contact arrangements. The plug-in contact system preferred from the current point of view is thus a plug-side first coding and / or latching means arranged on the outer surface with a first plug, a second plug with plug-in second coding and / or latching means arranged on the inside, one on a platinum edge attachable Kodierrahmen with internal, corresponding to the arranged on the outer surface of the first connector first encoding means first board-side coding and arranged on the outer surface of the first platinum-side locking means for cooperation with the first locking means of the first connector and on the board edge to which the Kodierrahmen can be placed arranged board-side second coding means for cooperating with the arranged on the inner surface of the second connector second coding means and provided in the circuit board second circuit board-side locking means for cooperating with the zw There are locking means of the second connector.

In einer den geltenden Normen entsprechenden Realisierung dieser bevorzugten Variante weisen die ersten Rastmittel des ersten Steckers und die zweiten Rastmittel des zweiten Steckers jeweils einen biegeelastischen Steckerfortsatz mit angeformter Rastnase auf, wobei insbesondere die ersten steckerseitigen Rastmittel außenliegend und die zweiten steckerseitigen Rastmittel innenliegend sind. Hierbei sind die platinenseitigen ersten und zweiten Rastmittel als Ausnehmungen im Kodierrahmen bzw. der Platine ausgebildet.In a corresponding to the applicable standards implementation of this preferred variant, the first locking means of the first connector and the second locking means of the second connector each have a flexurally elastic plug extension with molded locking lug, in particular the first plug-side locking means are outboard and the second plug-side locking means inside. Here, the board-side first and second locking means are formed as recesses in Kodierrahmen or the board.

Weiter bevorzugt haben die ersten Kodiermittel des ersten Steckers und die zweiten Kodiermittel des zweiten Steckers jeweils Vorsprünge auf der Außen- bzw. Innenoberfläche des Steckers oder sind durch eine geeignete Ausbildung der Steckerwandung realisiert. Die platinenseitigen ersten Kodiermittel sind dann Ausnehmungen in der Innenoberfläche des Kodierrahmens und die platinenseitigen zweiten Kodiermittel Kodierschlitze in der Platinenkante. Die Form und Anordnung der Stecker-Vorsprünge und Kodierrahmen- bzw. Platinen-Ausnehmungen ist im übrigen normgemäß und bedarf daher hier keiner genaueren Erläuterung.Further preferably, the first coding means of the first connector and the second coding means of the second connector each have projections on the outer or inner surface of the plug or are realized by a suitable design of the connector wall. The board-side first coding means are then recesses in the inner surface of the coding frame and the board-side second coding means coding slots in the board edge. The shape and arrangement of the plug-projections and Kodierrahmen- or sinker recesses is otherwise standard and therefore requires no further explanation here.

Fig. 1 zeigt - wie alle Figuren in Art einer Prinzipskizze, ohne Anspruch auf Maßstäblichkeit und vollständige Detailtreue - einen Ausschnitt aus einer Steckkontaktanordnung 1 für eine Geräteplatine 3 eines Hausgerätes. Die Steckkontaktanordnung umfasst neben einer speziellen Ausbildung der Platinenkante 3a der Geräteplatine 3 zum Aufstecken eines geeigneten Steckers (siehe Fig. 2) einen aufgesetzten Kodierrahmen 5. Die Verbindung des Kodierrahmens 5 mit der Geräteplatine 3 erfolgt in an sich bekannter Weise, ist in Fig. 1 nicht dargestellt und bedarf hier keiner genaueren Beschreibung. Fig. 1 shows - like all figures in the manner of a schematic diagram, without claim to scale and complete attention to detail - a section of a plug contact arrangement 1 for a device board 3 of a household appliance. The plug contact arrangement comprises in addition to a special design of the board edge 3a of the device board 3 for attaching a suitable plug (see Fig. 2 ) An attached Kodierrahmen 5. The connection of the Kodierrahmens 5 with the device board 3 is carried out in a conventional manner, is in Fig. 1 not shown and requires no detailed description here.

Zur Gewährleistung des verwechslungssicheren Aufsteckens eines passenden Steckers und zu dessen exakter Positionierung bezüglich der auf der Platine vorhandenen Anschluss-Leiterbahnen (nicht dargestellt) hat die Leiterplattenkante 3a Kodiermittel, und zwar zwei unterschiedlich lange und breite Kodierschlitze 7.1, 7.2. Zwischen diesen ist eine Bohrung 9 als platinenseitiges Rastmittel zum Zusammenwirken mit einem steckerseitigen Rastmittel vorgesehen, das mit diesem zusammen für eine zuverlässige Fixierung der Steckverbindung sorgt.To ensure the unmistakable Aufsteckens a matching connector and its exact positioning with respect to the existing on the board connection tracks (not shown) has the PCB edge 3a coding, namely two different long and wide coding slots 7.1, 7.2. Between these is a hole 9 as a platinum-side locking means for interacting with a plug-side Locking means provided, which together with this ensures a reliable fixation of the connector.

Zum Aufstecken auf die Platinenkante 3a ist ein Stecker 11 gemäß Fig. 2 mit Innenverrastung und Innenkodierung vorgesehen. In dessen Innerem ist ein elastisch federnder Kunststoffbügel 13 mit einer Rastnase 15 am freien Ende angebracht, welche zum Eingriff in die Bohrung 9 der Platine 3 ausgebildet ist. Eine geeignete Ausbildung der beiden Seitenwandungen 17.1, 17.2 dient zur Realisierung steckerseitiger Kodiermittel, welche mit den platinenseitigen Kodiermitteln (Kodierschlitzen) 7.1, 7.2 zusammenwirken.To attach to the board edge 3a is a plug 11 according to Fig. 2 provided with internal locking and internal coding. In the interior of an elastically resilient plastic strap 13 is mounted with a locking lug 15 at the free end, which is designed to engage in the bore 9 of the board 3. A suitable design of the two side walls 17.1, 17.2 serves for the realization of plug-side coding means, which interact with the board-side coding means (coding slots) 7.1, 7.2.

Im Kodierrahmen 5 gemäß Fig. 1 sind an einer Innenoberfläche zwei Kodiernuten 19.1, 19.2 als weitere platinenseitige Kodiermittel vorgesehen, und an der gegenüberliegenden Längsseite des Kodierrahmens befindet sich eine Ausnehmung 21 als weiteres platinenseitiges Rastmittel, neben der Bohrung 9 der Platine 3. Diese zusätzlichen Kodier- und Rastmittel ermöglichen das Zusammenwirken der Steckkontaktanordnung 1 mit einem weiteren Steckertyp, nämlich dem in Fig. 3 (wiederum als Prinzipskizze) dargestellten Stecker 23 mit Außenkodierung und Außenverrastung.In the coding frame 5 according to Fig. 1 are on an inner surface two Kodiernuten 19.1, 19.2 provided as further board-side coding, and on the opposite longitudinal side of the Kodierrahmens is a recess 21 as another platinenseitiges locking means, next to the bore 9 of the board 3. These additional coding and locking means allow the interaction of Plug contact arrangement 1 with a further plug type, namely the in Fig. 3 (again as a schematic diagram) shown plug 23 with external coding and external locking.

Hinsichtlich der - nicht dargestellten - Kontaktflächenanordnung entspricht dieser Stecker dem Stecker 11 nach Fig. 2, er unterscheidet sich von diesem aber dadurch, dass an einer Außenfläche zwei Kodiernasen 25.1, 25.2 in einer der Anordnung und Form der Kodiernuten 19.1, 19.2 des Kodierrahmens 5 entsprechenden Anordnung und Form vorgesehen sind. Weiterhin unterscheidet er sich von dem Stecker 11 mit Innenverrastung durch einen außenliegenden Kunststoffbügel 27 mit am freien Ende angeordneter Rastnase 29, die zum Eingriff in die Ausnehmung 21 am Kodierrahmen 5 ausgebildet ist.With regard to the contact surface arrangement (not shown), this plug corresponds to the plug 11 Fig. 2 , he differs from this but in that two coding tabs 25.1, 25.2 in an arrangement and shape of the Kodiernuten 19.1, 19.2 of the Kodierrahmens 5 corresponding arrangement and shape are provided on an outer surface. Furthermore, it differs from the plug 11 with Innenverrastung by an outer plastic bracket 27 with arranged at the free end locking lug 29 which is formed for engagement in the recess 21 on the Kodierrahmen 5.
