This would result in a fixed, non-floating attachment of the connector 3 on the electrical device 1 that the connector 3 can not be plugged together with the mating connector 4, since the allowable mounting tolerances between the connector 3 and the mating connector 4 is much lower than the mounting tolerances between the electrical device 1 and the base part 2 are.
- the required offset compensation of the connector 3 is made possible by the fact that the screw neck 15 of the fastening screw 12 is substantially narrower than the mounting hole 11, so that the connector 3 - in the illustration Fig. 3b - Is moved relative to the fixed screwed into the mounting plate 13 mounting screw 12 to the left.

- the connector 3 a contact insert 6 for the power supply of the electrical device 1 with a total of five contact elements 7 and five conductor terminals and a contact insert 6 with a plurality of contact elements. 7 - In the present case, 24 contact elements 7 - for the data transmission of the electrical Device 1 on.
- the mating connector 4 also has a mating contact insert 26 for the power supply and a mating contact insert 26 for the data transmission. The connector 3 and the mating connector 4 thus form a hybrid connector, with both the electrical supply of the electrical device 1 and the data transmission from and to the electrical device is realized.
- the mating connector 4 in addition to the two mating contact inserts 26 for the power supply and data transmission additionally a circuit board 28 and a total of three coding elements 29, wherein the coding elements 29 are connected via the circuit board 28 with the mating contact elements 27 of the contact insert 26 for data transmission.
- a circuit board 28 and a total of three coding elements 29, wherein the coding elements 29 are connected via the circuit board 28 with the mating contact elements 27 of the contact insert 26 for data transmission.

Daneben betrifft die Erfindung auch eine elektrische Steckverbindung zur Herstellung der elektrischen Verbindung zwischen einem elektrischen Gerät und einem ortsfesten Basisteil, mit einem an einer Befestigungsplatte des Geräts schwimmend befestigbaren Steckverbinder und einem am Basisteil befestigbaren korrespondierenden Gegensteckverbinder, wobei der Steckverbinder ein Gehäuse mit mindestens einem Kontakteinsatz mit mehreren Kontaktelementen und mindestens ein erstes Führungselement aufweist und wobei der Gegensteckverbinder ein Gehäuse mit mindestens einem Gegenkontakteinsatz mit mehreren Gegenkontaktelementen und mindestens ein zweites Führungselement aufweist, das beim Fügen von Steckverbinder und Gegensteckverbinder mit dem ersten Führungselement zusammenwirkt.The invention relates to an electrical device for mechanical and electrical connection to a stationary base part, with a connector which is connectable to a corresponding mating connector fixed to the base part, wherein the connector has a housing with at least one contact insert with a plurality of contact elements. In addition, the invention also relates to an electrical connector for making the electrical connection between an electrical device and a stationary base part, with a fixable to a mounting plate of the device connector and a fastened to the base member corresponding mating connector, wherein the connector comprises a housing having at least one contact insert a plurality of contact elements and at least one first guide element and wherein the mating connector has a housing having at least one mating contact insert with a plurality of mating contact elements and at least one second guide element which cooperates with the first guide element when joining connectors and mating connectors.
Bei dem eingangs genannten elektrischen Gerät handelt es sich vorzugsweise um ein relativ großes und schweres elektrisches Gerät, das mit einem ortsfesten Basisteil mechanisch verbunden bzw. auf dem Basisteil befestigt wird. Bei der Fertigstellung der mechanischen Verbindung erfolgt eine elektrische Verbindung zwischen dem elektrischen Gerät und dem Basisteil über den am elektrischen Gerät befestigten Steckverbinder und den am Basisteil angeordneten Gegensteckverbinder. Bei dem elektrischen Gerät kann es sich beispielsweise um einen Parkscheinautomaten, einen Informationsterminal oder ein Drehkreuz eines Personenzugangs handeln, welches auf einem als Basisteil dienenden Montageuntergrund befestigt wird. Ebenso gut kann es sich bei dem elektrischen Gerät auch um eine Ladestation für Fahrzeuge, um einen Spielautomaten oder um einen Beleuchtungsmasten handeln. All diesen elektrischen Geräten ist gemeinsam, dass es sich hierbei um relativ große und schwere Geräte handelt, die nicht oder nur mit Mühe und ggf. mit mehreren Personen von Hand auf das Basisteil aufgesetzt werden können. Darüber hinaus können die Montage- bzw. Führungshilfen, die zwischen dem elektrischen Gerät und dem Basisteil-zum Aufstecken oder Aufschieben des elektrischen Geräts auf das Basisteil - ausgebildet sind, Montagetolleranzen aufweisen, die wesentlich größer sind als die Montage- bzw. Lagetolleranzen mit denen der Steckverbinder mit dem korrespondierenden Gegensteckverbinder verbunden werden kann. Dies führt dazu, dass die elektrische Verbindung bei derartigen großen und schweren elektrischen Geräten mit einem ortsfesten Basisteil nicht oder nur mit größeren Schwierigkeiten mittels Steckverbindungen, insbesondere hochpoliger Steckverbindungen erfolgen kann.In the electrical device mentioned above, it is preferably a relatively large and heavy electrical device, which is mechanically connected or fixed to the base part with a stationary base part. When the mechanical connection is completed, an electrical connection is made between the electrical device and the base part via the plug connector fastened to the electrical device and the mating plug connector arranged on the base part. The electrical device can be, for example, a parking ticket machine, an information terminal or a turnstile of a passenger access, which is fastened on a mounting base serving as the base part. Equally well, the electrical device can also be a charging station for vehicles, a gaming machine or a lighting pole. All these electrical devices have in common that these are relatively large and heavy devices that can not or only with difficulty and possibly with several people by hand on the base part can be placed. In addition, the assembly or guide aids, which are formed between the electrical device and the base part-for plugging or pushing the electrical device on the base part - have assembly tolerances that are substantially larger than the assembly or Lagetolleranzen with which the connector can be connected to the corresponding mating connector. As a result, the electrical connection in such large and heavy electrical appliances with a stationary base part can not or only with greater difficulty by means of plug-in connections, in particular multi-pin connectors.

Darüber hinaus sind schwimmend gelagerte Steckverbinder aus der Praxis bekannt, die flexible Befestigungselemente aufweisen, wodurch jedoch nur ein Ausgleich von Bauteil- und Montagetoleranzen im Bereich von einigen zehntel Millimetern möglich ist, was jedoch im üblichen Bereich der Elektronik, zumeist ausreichend ist. Montagetolleranzen von mehr als einem Millimeter können mit derartigen Steckverbindern nicht ausgeglichen werden, so dass derartige Steckverbinder bzw. Steckverbindungen dann nicht eingesetzt werden können, wenn relativ große und schwere elektrische Geräte mit ortsfesten Basisteilen verbunden werden sollen, bei denen ein manuelles Ausrichten der Steckverbinderhälften unmittelbar zueinander nicht möglich ist und bei denen die Montagetolleranzen des Geräts zum Basisteil mehr als ein Millimeter betragen können.In addition, floating connectors are known in practice, have the flexible fasteners, which, however, only a balance of component and assembly tolerances in the range of a few tenths of a millimeter is possible, but this is usually sufficient in the usual field of electronics. Assembly tolerances of more than one millimeter can not be compensated with such connectors, so that such connectors or connectors can not be used when relatively large and heavy electrical equipment to be connected to stationary base parts in which a manual alignment of the connector halves directly to each other is not possible and where the mounting tolerances of the device to the base part can be more than a millimeter.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein eingangs beschriebenes elektrisches Gerät mit einem Steckverbinder sowie eine elektrische Steckverbindung bestehend aus einem Steckverbinder und einem korrespondierenden Gegensteckverbinder zur Verfügung zu stellen, bei dem die zuvor beschriebenen Probleme möglichst vermieden und ein Ausgleich auch von relativ großen Montagetolleranzen zwischen dem Steckverbinder und dem Gegensteckverbinder beim Zusammenfügen des elektrischen Geräts mit dem ortsfesten Basisteil ausgeglichen werden können.The present invention is therefore an object of the invention to provide an electrical device described above with a connector and an electrical connector consisting of a connector and a corresponding mating connector, in which the problems described above avoided as possible and a balance of relatively large assembly tolerances between the connector and the mating connector when assembling the electrical device with the stationary base part can be compensated.
Diese Aufgabe ist bei dem eingangs beschriebenen elektrischen Gerät dadurch gelöst, dass der Steckverbinder wenigstens ein erstes Führungselement aufweist, das beim Verbinden des elektrischen Geräts mit dem Basisteil mit einem im Gehäuse des Gegensteckverbinders ausgebildeten zweiten Führungselement zusammenwirkt und dass im Gehäuse des Steckverbinders mindestens ein Schraubenloch ausgebildet ist, wobei der Steckverbinder dadurch über mindestens eine das Schraubloch durchsetzende Befestigungsschraube schwimmend an einer Befestigungsplatte des Geräts befestigt ist, dass die Befestigungsschraube einen Schraubenkopf, einen Schraubenhals und ein Schraubenende mit einem Gewinde aufweist, wobei der Durchmesser des Schraubenkopfes größer als der Durchmesser des Schraubenlochs und der Durchmesser des Schraubenhalses wesentlich kleiner als der Durchmesser des Schraubenlochs ist.This object is achieved in the electrical device described above in that the connector has at least one first guide element, which in connecting the electrical device to the base part with a housing in the At least one screw hole is formed in the housing of the connector, wherein the connector is thereby secured via at least one fastening screw passing through the screw floating on a mounting plate of the device, that the fastening screw a screw head, a screw neck and a screw end with a Has thread, wherein the diameter of the screw head is greater than the diameter of the screw hole and the diameter of the screw neck is substantially smaller than the diameter of the screw hole.
Durch die schwimmende Befestigung des Steckverbinders an der Befestigungsplatte des elektrischen Geräts ist eine Toleranz ausgleichende Bewegung des Steckverbinders senkrecht zur Fügerichtung des elektrischen Geräts möglich, wobei der Steckverbinder um die Differenz des Durchmessers des Schraubenlochs zum Durchmessers des Schraubenhalses verschiebbar ist. Ist der Durchmesser des Schraubenhalses deutlich kleiner als der Durchmesser des Schraubenloches, so ist ein Toleranzausgleich von mehr als ein Millimeter, beispielsweise ± 2 mm in allen Richtungen senkrecht oder quer zur Fügerichtung möglich.By the floating attachment of the connector to the mounting plate of the electrical device, a tolerance compensating movement of the connector perpendicular to the joining direction of the electrical device is possible, wherein the connector by the difference of the diameter of the screw hole to the diameter of the screw neck is displaceable. If the diameter of the screw neck is significantly smaller than the diameter of the screw hole, a tolerance compensation of more than one millimeter, for example ± 2 mm in all directions perpendicular or transverse to the joining direction is possible.
Die Führungselemente sind vorzugsweise als Führungszapfen und Führungslöcher ausgebildet, wobei bevorzugt am Gehäuse des Steckverbinders mindestens zwei Führungszapfen und im Gehäuse des Gegensteckverbinders zwei Führungslöcher ausgebildet sind. Bei der mechanischen Verbindung des elektrischen Geräts mit dem ortsfesten Basisteil greifen zunächst die Führungszapfen, deren freien Enden die Vorderseite des Steckverbinders überragen, in die im Gehäuse des Gegensteckverbinders ausgebildeten korrespondierenden Führungslöcher ein. Beim weiteren Zusammenfügen von elektrischem Gerät und ortsfestem Basisteil wird dann der Steckverbinder dadurch mit großer Genauigkeit zum Gegensteckverbinder ausgerichtet, dass der Steckverbinder senkrecht bzw. quer zur Fügerichtung schwimmend, d. h. innerhalb bestimmter Grenzen beweglich, an der Befestigungsplatte des elektrischen Geräts angeordnet ist. Beim Einstecken der Führungszapfen in die Führungslöcher wird das Gehäuse des Steckverbinders automatisch in die richtige Position verschoben, so dass der Kontakteinsatz des Steckverbinders mit dem Gegenkontakteinsatz des Gegensteckverbinders zusammen gesteckt werden kann. Anstelle der Ausbildung einer oder mehrerer Führungszapfen am Gehäuse des Steckverbinders und korrespondierender Führungslöcher im Gehäuse des Gegensteckverbinders kann auch der Gegensteckverbinder entsprechende Führungszapfen und der Steckverbinder korrespondierende Führungslöcher aufweisen.The guide elements are preferably designed as guide pins and guide holes, wherein preferably at the housing of the connector at least two guide pins and in the housing of the mating connector two guide holes are formed. In the mechanical connection of the electrical device to the stationary base part, the guide pins, whose free ends project beyond the front side of the connector, first engage in the corresponding guide holes formed in the housing of the mating connector. Upon further assembly of the electrical device and stationary base part of the connector is then aligned with great accuracy to the mating connector, that the connector is perpendicular or transverse to the joining direction floating, ie movable within certain limits, arranged on the mounting plate of the electrical device. When inserting the guide pin in the guide holes, the housing of the connector is automatically moved to the correct position, so that the contact insert of the connector can be plugged together with the mating connector insert of the mating connector. Instead of forming one or more guide pins on the housing of the connector and corresponding guide holes in the housing of the mating connector can also the mating connector corresponding guide pin and the connector have corresponding guide holes.
Gemäß der Erfindung weist die Befestigungsschraube einen Schraubenanschlag auf, durch die der maximale Einschraubweg der Befestigungsschraube in die Befestigungsplatte des elektrischen Geräts begrenzt wird. Dadurch wird sichergestellt, dass der Schraubenkopf in axialer Richtung der Befestigungsschraube etwas Spiel zum Gehäuse des Steckverbinders hat, so dass die gewollte schwimmende Befestigung des Steckverbinders an der Befestigungsplatte nicht durch ein zu festes Anziehen der Befestigungsschraube zunichte gemacht wird. Hierzu ist der Schraubenanschlag derart zwischen dem Schraubenhals und dem Schraubenende angeordnet, dass der Abstand zwischen der dem Schraubenhals zugewandten Unterseite des Schraubenkopfes und der dem Schraubenende zugewandten Unterseite des Schraubenanschlags etwas größer ist als die Länge des Schraubenloches im Gehäuse des Steckverbinders. Anders ausgedrückt bedeutet dies, dass die Länge des Schraubenhalses und die Dicke des Schraubenanschlages zusammen größer sind als die Dicke des Gehäuses des Steckverbinders im Bereich des Schraubenloches.According to the invention, the fastening screw on a screw stop, by which the maximum screwing of the fastening screw is limited in the mounting plate of the electrical device. This ensures that the screw head has some play in the axial direction of the fastening screw to the housing of the connector, so that the intended floating attachment of the connector to the mounting plate is not nullified by over tightening the mounting screw. For this purpose, the screw stop is arranged between the screw neck and the screw end, that the distance between the screw neck facing the underside of the screw head and the screw end facing the bottom of the screw stop is slightly larger than the length of the screw hole in the housing of the connector. In other words, this means that the length of the screw neck and the thickness of the screw stop together are greater than the thickness of the housing of the connector in the region of the screw hole.
Der Schraubenanschlag ist vorzugsweise ringförmig ausgebildet, so dass er den Schraubenhals vollständig nach Art eines Kragens umgibt, wobei der Schraubenanschlag einen Außendurchmesser aufweist, der deutlich größer als der Durchmesser des Schraubenhalses und nur etwas kleiner als der Durchmesser des Schraubenkopfes bzw. der Durchmesser des Schraubenloches ist. Dadurch wird eine relativ große Auflagefläche des Schraubenanschlags auf der Oberseite der Befestigungsplatte erreicht, so dass die Befestigungsschraube mit relativ großem Drehmoment angezogen werden kann. Hierdurch wird gewährleistet, dass der Steckverbinder auch bei relativ rauen Umgebungsbedingungen, insbesondere bei großen Temperaturschwankungen, dauerhaft und sicher an der Befestigungsplatte des elektrischen Gerätes befestigt ist.The screw stop is preferably annular, so that it surrounds the screw neck completely in the manner of a collar, wherein the screw stop has an outer diameter which is significantly larger than the diameter of the screw neck and only slightly smaller than the diameter of the screw head or the diameter of the screw hole , As a result, a relatively large bearing surface of the screw stop on the top of the mounting plate is achieved, so that the fastening screw can be tightened with a relatively large torque. This ensures that the connector is permanently and securely attached to the mounting plate of the electrical device even in relatively harsh environmental conditions, especially in large temperature fluctuations.
Um zu verhindern, dass die maximal mögliche Beweglichkeit des Steckverbinders senkrecht zur Fügerichtung des elektrischen Geräts durch den größeren Außendurchmesser des zuvor beschriebenen Schraubenanschlags reduziert ist, ist, gemäß der Erfindung, im Gehäuse des Steckverbinders an dem der Befestigungsplatte des Geräts zugewandten Ende des Schraubenloches eine Öffnung ausgebildet, deren Durchmesser größer als der Durchmesser des Schraubenloches ist. Durch die Ausbildung einer derartigen, an das Schraubenloch anschließenden Öffnung mit einem größeren Durchmesser wird sichergestellt, dass die gewollte Beweglichkeit des Steckverbinders quer zur Fügerichtung durch die Differenz des Durchmessers des Schraubenloches zum Durchmesser des Schraubenhalses bestimmt wird und nicht vom Außendurchmesser des Schraubenanschlags abhängt.In order to prevent the maximum possible mobility of the connector is reduced perpendicular to the joining direction of the electrical device by the larger outer diameter of the screw stop described above, according to the invention, in the housing of the connector on the mounting plate of the device facing the end of the screw hole an opening formed, whose diameter is larger than the diameter of the screw hole. Through the training of such, at the screw hole subsequent opening with a larger diameter ensures that the desired mobility of the connector is determined transversely to the joining direction by the difference of the diameter of the screw hole to the diameter of the screw neck and does not depend on the outer diameter of the screw stop.
Zuvor ist ausgeführt worden, dass das elektrische Gerät, bei dem es sich beispielsweise um einen Parkscheinautomaten, einen Informationsterminal oder eine Ladestation für Fahrzeuge handeln kann, mechanisch mit einem als Montageuntergrund dienen ortsfesten Basisteil verbunden wird. Um die Montage eines derartigen elektrischen Geräts mit dem Basisteil zu vereinfachen, weist das elektrische Gerät gemäß einer vorteilhaften Ausgestaltung mindestens zwei senkrecht zur Befestigungsplatte verlaufende Führungshilfen auf, die beim Verbinden des Geräts mit dem ortsfesten Basisteil mit korrespondierenden Führungshilfen zusammen wirken. Bei den am elektrischen Gerät vorgesehenen Führungshilfen kann es sich beispielsweise um Führungsstege und bei den am ortsfesten Basisteil ausgebildeten Führungshilfen um korrespondierende Führungsnuten handeln.It has previously been stated that the electrical device, which can be, for example, a parking ticket machine, an information terminal or a charging station for vehicles, is mechanically connected to a stationary base part serving as mounting base. In order to simplify the mounting of such an electrical device with the base part, the electrical device according to an advantageous embodiment, at least two perpendicular to the mounting plate guide aids, which act together with corresponding guide aids when connecting the device to the stationary base part. The guide aids provided on the electrical device may, for example, be guide webs and, in the case of the guide aids formed on the stationary base part, correspond to corresponding guide grooves.
Die zuvor genannte Aufgabe ist bei einer eingangs beschriebenen elektrischen Steckverbindung gemäß den Merkmalen des kennzeichnenden Teils des Patentanspruchs 8 dadurch gelöst, dass im Gehäuse des Steckverbinders mindestens ein Schraubenloch ausgebildet ist, durch das eine das Schraubenloch durchsetzende Befestigungsschraube in eine Bohrung in einer Befestigungsplatte eines elektrischen Geräts einschraubbar ist, und dass die Befestigungsschraube einen Schraubenkopf, einen Schraubenhals und ein Schraubenende mit einem Gewinde aufweist, wobei der Durchmesser des Schraubenkopfs größer als der Durchmesser des Schraubenlochs und der Durchmesser des Schraubenhals wesentlich kleiner als der Durchmesser des Schraubenlochs ist.The aforementioned object is achieved in an electrical connector described above according to the features of the characterizing part of
Wie zuvor bereits im Zusammenhang mit dem erfindungsgemäßen elektrischen Gerät ausgeführt worden ist, ist ein Ausgleich von Montagetolleranzen zwischen dem an einem elektrischen Gerät befestigbaren Steckverbinder und dem an einem ortsfesten Basisteil befestigbaren Gegensteckverbinder durch eine schwimmende Lagerung des Steckverbinders an dem elektrischen Gerät bzw. an einer Befestigungsplatte des elektrischen Geräts realisiert. Durch die Ausbildung mindestens eines Schraubenloches und die besondere Ausgestaltung der Befestigungsschraube mit einem schmalen Schraubenhals ist eine Bewegung des Steckverbinders senkrecht oder quer zur Fügerichtung möglich, die durch die Differenz des Durchmessers des Schraubenloches zum Durchmesser des Schraubenhalses begrenzt ist. Je schmaler der Schraubenhals und je größer der Durchmesser des Schraubenloches ist, desto größer ist der maximal mögliche Versatz zwischen dem Steckverbinder und dem Gegensteckverbinder, der beim Fügen von Steckerverbinder und Gegensteckverbinder bzw. beim Aufstecken oder Aufschieben des elektrischen Geräts auf das Basisteil durch eine gewollt ermöglichte Querbewegung des Steckverbinders ausgeglichen werden kann.As has already been explained in connection with the electrical device according to the invention, a compensation of assembly tolerances between the attachable to an electrical device connector and attachable to a stationary base mating connector by a floating mounting of the connector to the electrical device or to a mounting plate realized the electrical device. By forming at least one screw hole and the particular configuration of the fastening screw with a narrow Screw neck is a movement of the connector perpendicular or transverse to the joining direction possible, which is limited by the difference of the diameter of the screw hole to the diameter of the screw neck. The narrower the screw neck and the larger the diameter of the screw hole, the greater the maximum possible offset between the connector and the mating connector, which allowed by a wanted when joining plug connector and mating connector or when plugging or pushing the electrical device to the base part Transverse movement of the connector can be compensated.
Wie zuvor ebenfalls im Zusammenhang mit dem erfindungsgemäßen elektrischen Gerät ausgeführt worden ist, weist die Befestigungsschraube einen Schraubenanschlag auf, durch den der maximale Einschraubweg der Befestigungsschraube begrenzt wird, so dass der Steckverbinder in axialer Richtung mit ausreichend Spiel mit der Befestigungsplatte verbindbar ist, so dass die gewollte schwimmende Lagerung des Steckverbinders nicht beeinträchtigt wird.As has also been carried out in connection with the electrical device according to the invention, the fastening screw has a screw stop, by which the maximum screwing of the fastening screw is limited, so that the connector in the axial direction with sufficient clearance with the mounting plate is connectable, so that the desired floating mounting of the connector is not affected.
Um automatisch eine möglichst genaue Ausrichtung des Steckverbinders zum Gegensteckverbinder beim Fügevorgang zu erreichen, weist der Steckverbinder vorzugsweise zwei Führungszapfen und der Gegensteckverbinder zwei korrespondierende Führungslöcher auf, wobei die Führungszapfen und die Führungslöcher in der Ebene senkrecht zur Fügerichtung des Steckverbinders diagonal zueinander angeordnet sind. Das selbständige Eingreifen der Führungszapfen in die Führungslöcher wird vorzugsweise dadurch weiter verbessert, dass die Führungszapfen kegelförmige Spitzen aufweisen, so dass die Führungszapfen auch bei einem anfänglichen Versatz ihrer Längsachsen zu den Längsachsen der Führungslöcher über die kegelförmigen Spitzen in die Führungslöcher gleiten.To automatically achieve the most accurate alignment of the connector to the mating connector during the joining process, the connector preferably has two guide pins and the mating connector two corresponding guide holes, wherein the guide pins and the guide holes are arranged in the plane perpendicular to the joining direction of the connector diagonally to each other. The independent engagement of the guide pins in the guide holes is preferably further improved in that the guide pins have conical tips, so that the guide pins slide into the guide holes even with an initial offset of their longitudinal axes to the longitudinal axes of the guide holes on the conical tips.
Gemäß einer weiteren vorteilhaften Ausgestaltung der elektrischen Steckverbindung weist der Steckverbinder mehrere Kontakteinsätze mit unterschiedlichen Kontaktelementen und der Gegensteckverbinder mehrere Gegenkontakteinsätze mit unterschiedlichen, jedoch zu den zugeordneten Kontaktelementen korrespondierenden Gegenkontaktelementen auf. Dabei dient vorzugsweise mindestens ein Kontakteinsatz und ein Gegenkontakteinsatz der Stromversorgung und mindestens ein Kontakteinsatz und ein Gegenkontakteinsatz der Datenübertragung vom elektrischen Gerät zum Basisteil und umgekehrt. Bei der erfindungsgemäßen elektrischen Steckverbindung handelt es sich somit vorzugsweise um eine Hybrid-Steckverbindung, d. h. eine Kombination von Steckverbindung für die Energieversorgung und Steckverbindung für die Datenübertragung. Gerade bei einer solchen elektrischen Steckverbindung, welche eine Vielzahl von Kontaktelementen und korrespondierenden Gegenkontaktelementen aufweist, sind zwischen dem Steckverbinder und dem Gegensteckverbinder nur sehr geringe Bauteil- und Montagetolleranzen zulässig. Ist ein Steckverbinder einer derartigen elektrischen Steckverbindung an einem relativen großen und schweren elektrischen Gerät befestigt, so müssen die zwischen dem ortsfesten Basisteil und dem elektrischen Gerät zulässigen, relativ großen Bauteil- und Montagetolleranzen durch die schwimmende Lagerung des Steckverbinders ausgeglichen werden, damit die einzelnen Kontakteinsätze des Steckverbinders mit den korrespondierenden Gegenkontakteinsätzen des Gegensteckverbinders einwandfrei zusammengesteckt werden können.According to a further advantageous embodiment of the electrical connector, the connector has a plurality of contact inserts with different contact elements and the mating connector a plurality of mating contact inserts with different, but to the associated contact elements corresponding mating contact elements. In this case, preferably at least one contact insert and a mating contact insert of the power supply and at least one contact insert and a mating contact insert of the data transmission from the electrical device to the base part and vice versa is used. The electrical connector according to the invention is thus preferably a hybrid connector, ie a Combination of plug connection for the power supply and plug connection for the data transmission. Especially with such an electrical connector, which has a plurality of contact elements and corresponding mating contact elements, only very small component and assembly tolerances are allowed between the connector and the mating connector. Is a connector of such an electrical connector attached to a relatively large and heavy electrical device, the permissible between the stationary base and the electrical device, relatively large component and assembly tolerances must be compensated by the floating mounting of the connector so that the individual contact inserts of Connector can be properly mated with the corresponding mating contact inserts of the mating connector.
Bei einer derartigen elektrischen Steckverbindung weist gemäß einer letzten vorteilhaften Ausgestaltung der Erfindung der Gegensteckverbinder neben den Gegenkontakteinsätzen zusätzlich noch eine Leiterplatte und mindestens ein Kodierelement auf, wobei das Kodierelement über die Leiterplatte mit Gegenkontaktelementen eines Kontakteinsatzes für die Datenübertragung verbunden ist.In such an electrical connector, according to a final advantageous embodiment of the invention, the mating connector in addition to the mating contact inserts additionally a printed circuit board and at least one coding, wherein the coding element is connected via the circuit board with mating contact elements of a contact insert for data transmission.
Handelt es sich bei dem elektrischen Gerät, an dem der Steckverbinder befestigt ist, beispielsweise um einen Parkscheinautomat, der auf einem Montageuntergrund als Basisteil montiert wird, so kann es erforderlich sein, dass zur Kennzeichnung der genauen Position des Parkscheinautomats eine bestimmte Kodierung eingestellt wird, die dann zusammen mit den Daten des Parkscheinautomats über einen mit dem Basisteil verbundenen Busanschluss, beispielsweise einen Ethernet-Anschluss, an einen Zentralrechner übermittelt wird. Zur Einstellung der entsprechenden Kodierung vor Ort ist am Gegensteckverbinder mindestens ein Kodierelement vorgesehen, das vom Monteur vor dem Aufstecken des Parkscheinautomats auf das als Montageuntergrund dienende Basisteil entsprechend eingestellt wird. Bei dem Kodierelement kann es sich dabei vorzugsweise um mehrere Drehschalter handeln, die auf der im Gegensteckverbinder angeordneten Leiterplatte angebracht sind.If the electrical device to which the connector is attached, for example, a parking ticket machine, which is mounted on a mounting surface as a base part, it may be necessary that a specific coding is set to identify the exact position of the parking ticket machine then transmitted together with the data of the parking ticket machine via a bus connected to the base part bus, for example, an Ethernet connection to a central computer. To set the appropriate coding on site, at least one coding element is provided on the mating connector, which is set by the installer before attaching the parking ticket machine to the serving as a mounting base base accordingly. The coding element may preferably be a plurality of rotary switches which are mounted on the printed circuit board arranged in the mating connector.

Der Steckverbinder 3 weist ein Gehäuse 5 mit zwei Kontakteinsätzen 6 auf, wobei die beiden Kontakteinsätze 6 jeweils eine Mehrzahl von Kontaktelementen 7 aufweisen. Darüber hinaus weist der Steckverbinder 3 noch zwei Führungszapfen 8 auf, die beim Verbinden des elektrischen Geräts 1 mit dem Basisteil 2 in zwei im Gehäuse 9 des Gegensteckverbinders 4 ausgebildete Führungslöcher 10 eingreifen. Da die Führungszapfen 8 die dem Gegensteckverbinder 4 zugewandte Stirnseite des Steckverbinders 3 bzw. der Kontakteinsätze 6 überragen, greifen beim Zusammenfügen von elektrischem Gerät 1 und Basisteil 2 zunächst die Führungszapfen 8 in die Führungslöcher 10 ein, wodurch eine Ausrichtung des schwimmend am Gerät 1 befestigten Steckverbinders 3 zum Gegensteckverbinder 4 erfolgt, wie dies insbesondere anhand der drei Darstellungen der
Die schwimmende Befestigung des Steckverbinders 3 am elektrischen Gerät 1 wird dadurch realisiert, dass im Gehäuse 5 des Steckverbinders 3 zwei Schraubenlöcher 11 ausgebildet sind, die jeweils von einer Befestigungsschraube 12 durchsetzt sind, die in einer Befestigungsplatte 13 des Geräts 1 eingeschraubt sind. Die in
Die Befestigungsschrauben 12 weisen neben dem Schraubenkopf 14, dem Schraubenhals 15 und dem Schraubenende 16 noch einen ringförmigen Schraubenanschlag 17 auf, der zwischen dem Schraubenhals 15 und dem Schraubenende 16 angeordnet ist und die maximale Einschraubtiefe der Befestigungsschraube 12 in die Befestigungsplatte 13 derart begrenzt, dass der Schraubenkopf 14 in axialer Richtung der Befestigungsschraube 12 etwas Spiel zum Gehäuse 4 des Steckverbinders 3 aufweist. Hierzu sind die Länge des Schraubenhalses 15 und die Dicke des Schraubenanschlags 17 so gewählt, dass der Abstand zwischen der dem Schraubenhals 15 zugewandten Unterseite 18 des Schraubenkopfes 14 und der dem Schraubenende 16 zugewandten Unterseite 19 des Schraubenanschlags 17 etwas größer ist als die Länge des Schraubenlochs 11. Wie aus
Der ringförmige, das Schraubenende 16 nach Art eines Kragens umgebende Schraubenanschlag 17 weist einen Außendurchmesser auf, der deutlich größer als der Durchmesser des Schraubenendes 16 bzw. des Schraubenhalses 15 ist. Dadurch wird eine relativ große Auflagefläche des Schraubenanschlags 17 auf der Oberseite 21 der Befestigungsplatte 13 erreicht, so dass die Befestigungsschraube 12 mit einem relativ großen Drehmoment angezogen werden kann. Dies gewährleistet eine sichere und dauerhafte Befestigung des Steckverbinders 3 an dem elektrischen Gerät 1, auch wenn das elektrische Gerät 1 aufgrund relativ rauer Umgebungsbedingungen relativ großen Temperaturschwankungen ausgesetzt ist. Damit die gewollte maximal mögliche Verschiebbarkeit des Steckverbinders 3 senkrecht zur - in

Aufgrund der kegelförmigen Spitze 23 der Führungszapfen 8 gelangen diese beim weiteren Einschieben der Führungsstege 24 des Geräts 1 in die Führungsnuten 25 des Basisteils 2 trotz des Versatzes in die Führungslöcher 10, was zu einer Querverschiebung des Steckverbinders 3 senkrecht zur Fügerichtung F führt. Die schwimmende Befestigung des Steckverbinders 3 an der Befestigungsplatte 13 des Geräts 1 ermöglicht es somit, dass der Steckverbinder 3 durch die selbst erfolgende Ausrichtung von Führungszapfen 8 und Führungslöchern 10 zueinander relativ zur Befestigungsplatte 13 verschoben wird, so dass der Steckverbinder 3 beim weiteren Aufschieben des Geräts 1 auf das Basisteil 2 mit dem Gegensteckverbinder 4 zusammengesteckt werden kann (
Der hierzu erforderliche Versatzausgleich des Steckverbinders 3 wird dadurch ermöglicht, dass der Schraubenhals 15 der Befestigungsschraube 12 wesentlich schmaler als das Befestigungsloch 11 ist, so dass der Steckverbinder 3 - in der Darstellung gemäß

Bei dem in den Figuren dargestellten Ausführungsbeispiel des erfindungsgemäßen elektrischen Geräts 1 bzw. der erfindungsgemäßen elektrischen Steckverbindung weist der Steckverbinder 3 einen Kontakteinsatz 6 für die Stromversorgung des elektrischen Geräts 1 mit insgesamt fünf Kontaktelementen 7 und fünf Leiteranschlüssen und einen Kontakteinsatz 6 mit einer Mehrzahl von Kontaktelementen 7 - im vorliegenden Fall 24 Kontaktelementen 7 - für die Datenübertragung des elektrischen Geräts 1 auf. Korrespondierend dazu weist auch der Gegensteckverbinder 4 einen Gegenkontakteinsatz 26 für die Stromversorgung und einen Gegenkontakteinsatz 26 für die Datenübertragung auf. Der Steckverbinder 3 und der Gegensteckverbinder 4 bilden somit eine Hybrid-Steckverbindung, mit der sowohl die elektrische Versorgung des elektrischen Geräts 1 als auch die Datenübertragung von und zum elektrischen Gerät realisiert wird.In the embodiment illustrated in the figures of the

Bei dem in den Figuren dargestellten elektrischen Gerät 1, an dem der Steckverbinder 3 befestigt ist, handelt es sich um ein relativ großes und schweres Gerät, welches nicht ohne weiteres von Hand auf das ortsfeste Basisteil 2 als Montageuntergrund montiert werden kann. Bei dem elektrischen Gerät 1 kann es sich dabei beispielsweise um ein Drehkreuz eines Personenzugangs, einen Informationsterminal oder einen Parkscheinautomaten handeln. Handelt es sich bei dem elektrischen Gerät 1 beispielsweise um einen Parkscheinautomaten, so kann über die im Gegensteckverbinder 4 ausgebildeten Kodierelemente 29 vor der Montage des Parkscheinautomats eine der Position des Parkscheinautomats entsprechende Kodierung vom Monteur eingestellt werden, so dass die an eine zentrale Leitstelle übermittelten Daten dem "richtigen" Parkscheinautomaten zugeordnet werden können.In the illustrated in the figures
