Description

Die Erfindung bezieht sich auf eine mehrpolige, codierte, vorzugsweise dreipolige Gerätesteckvorrichtung mit an den Gehäusen angeformten, die Stifte bzw. Buchsenkontakte überragenden Berührungsschutzhülsen, wobei die die Buchsenkontakte umschließenden Berührungsschutzhülsen in die die Stifte mit Abstand umgebenden Berührungsschutzhülsen einschiebbar sind.The invention relates to a multi-pole, coded, preferably three-pole device plug-in device with molded-on contact sleeves protruding from the housings, the protective sleeves surrounding the pins or socket contacts, the protective sleeves surrounding the socket contacts being insertable into the protective sleeves surrounding the pins at a distance.

Steckverbindungen, bei denen sowohl die Stiftals auch die Buchsenkontakte durch überragende Hülsen berührungsgeschützt abgedeckt sind und die darüber hinaus meist noch eine Codierung aufweisen, um ein Zusammenstecken nicht zusammengehöriger Steckverbinderteile oder ein seitlich versetztes Zusammenstecken zu verhindern, sind bereits in unterschiedlichen Ausführungsformen bekanntgeworden (siehe DE 22 06 753, DE 28 07 016, DE 31 08 744 und DE 34 40 043). Diese kommen überwiegend im industriellen, gewerblichen und Installations-Bereich zur Anwendung, wo sie dem Zugriff von Laien entzogen sind. Weitere Vorteile der bekannten Steckverbinder, wie z.B. die eindeutige Polzuordnung, haben jedoch immer wieder Anwender dazu veranlaßt, diese Steckverbinder auch im Sinne einer Gerätesteckvorrichtung einzusetzen, wodurch diese auch Eingang in den Anwendungsbereich von Haushaltsgeräten finden. Wenn darüber hinaus eine eindeutige Zuordnung verschiedener Stromkreise zu steckbaren Stromausgängen z.B. eines Schaltkastens oder einer Schaltzentrale durch unverwechselbare Gerätesteckvorrichtungen gleicher Bauart gegeben ist, wird die Verdrahtung einer Anlage bzw. die Installation z.B. eines Messestandes derart vereinfacht, daß die Endmontage häufig von Nicht-Fachleuten vorgenommen wird.Plug-in connections in which both the pin and the socket contacts are covered so as to be protected from contact by outstanding sleeves and which, moreover, usually also have a coding in order to prevent plug-in connector parts that do not belong together or a laterally offset plug-in connection, have already become known in various embodiments (see DE 22 06 753, DE 28 07 016, DE 31 08 744 and DE 34 40 043). These are mainly used in industrial, commercial and installation areas, where they are not accessible to laypeople. Other advantages of the known connectors, such as the clear pole assignment, however, have repeatedly prompted users to use these plug-in connectors also in the sense of a device connector, as a result of which they are also used in the field of household appliances. If, moreover, there is a clear assignment of different circuits to pluggable current outputs e.g. a control box or a control center is provided by distinctive device connectors of the same design, the wiring of a system or the installation e.g. of a booth so simplified that final assembly is often carried out by non-specialists.

Da Gerätesteckvorrichtungen im Einklang mit den einschlägigen Normen unter Last gezogen werden dürfen, kann das Steckvorrichtungsteil mit den Buchsenkontakten auch in nichtgestecktem Zustand unter Spannung stehen. Hierdurch ergibt sich aber die Gefahr, daß gerade technisch nicht versierte Benutzer die Bedeutung der Steckerteile verkennen und versuchen, das spannungsführende Buchsenteil beispielsweise mit einem normalen Stecker einer Haushalts-Gerätesteckvorrichtung zu verbinden. Dies gelingt zwar wegen der unterschiedlichen Durchmesser der Buchsenkontakte des Steckverbinderteiles und der Stifte eines genormten Schutzkontaktsteckers (Schuko-Stecker) nicht vollständig, doch ist aufgrund der Ausbildung der Berührungsschutzhülsen bei den bekannten Steckverbindern ein Eingreifen der Steckerstifte eines solchen Schuko-Steckers in die Berührungsschutzhülse und damit ein Kontakt mit den spannungsführenden Buchsenkontakten möglich.Since device connectors can be pulled under load in accordance with the relevant standards, the connector part with the socket contacts can be live even when not plugged in. However, this creates the danger that technically inexperienced users misunderstand the meaning of the connector parts and try to connect the live socket part, for example, to a normal plug of a household appliance connector. Although this is not completely possible due to the different diameters of the socket contacts of the connector part and the pins of a standardized protective contact plug (Schuko plug), due to the design of the contact protection sleeves in the known connectors, the plug pins of such a Schuko plug engage in the contact protection sleeve and thus contact with the live socket contacts possible.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Gerätesteckvorrichtung der eingangs genannten Art so auszugestalten, daß einerseits eine gefahrbringende Verwechslung mit genormten Haushalts- oder Gerätesteckvorrichtungen, wie z.B. den als Schuko-Steckern bekannten Schutzkontaktstekkern sicher vermieden wird und andererseits eine Reihe unverwechselbarer Gerätesteckvorrichtungen gleicher Bauart zur Verfügung steht.The invention is therefore based on the object of designing a device connector of the type mentioned in such a way that, on the one hand, a dangerous confusion with standardized household or device connectors, such as e.g. the safety plug connectors known as Schuko plugs are safely avoided and, on the other hand, a number of distinctive device connectors of the same type are available.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Berührungsschutzhülsen die Buchsenkontakte eng umschließen, daß die Berührungsschutzhülsen der Buchsenkontakte vorne im Überstandsbereich über die Buchsenkontakte auf den Außendurchmesser der Stiftkontakte eingeengt sind und daß die äußere Kontur der Berührungsschutzhülsen der Buchsenkontakte formschlüssig und paßgenau der inneren Kontur der Berührungsschutzhülsen der Stiftkontakte entspricht.To achieve this object, it is provided according to the invention that the contact protection sleeves tightly enclose the socket contacts, that the contact protection sleeves of the socket contacts are narrowed at the front in the protruding area over the socket contacts to the outside diameter of the pin contacts, and that the outer contour of the contact protection sleeves of the socket contacts is form-fitting and precisely fitting the inner contour of the inner contacts Protection against contact of the pin contacts.

Durch die erfindungsgemäße Vertauschung der Ausbildung der Berührungsschutzhülsen - üblicherweise sind bei den bekannten Steckverbindern die Buchsen mit in Abstand davon angeordneten Berührungsschutzhülsen ausgestattet, so daß zwischen die Buchsenkontakte und die Innenwand ihrer Berührungsschutzhülsen die Berührungsschutzhülsen der Stifte eingeführt werden können - sind die Öffnungen der Berührungsschutzhülsen der Buchsenkontakte am vorderen Ende so stark reduziert, daß eine gefahrbringende Einführung genormter Steckvorrichtungen wie z.B. Schutzkontaktsteckern nicht möglich ist.Due to the swapping of the design of the contact protection sleeves according to the invention - the sockets in the known connectors are usually equipped with contact protection sleeves arranged at a distance therefrom so that the contact protection sleeves of the pins can be inserted between the socket contacts and the inner wall of their contact protection sleeves - the openings of the contact protection sleeves of the socket contacts so much reduced at the front end that a dangerous introduction of standardized connectors such as Earthing plugs are not possible.

Diese Gefahr ist noch dadurch weiter verkleinert, daß die Berührungsschutzhülsen der Buchsenteile vorne im Überstandsbereich über die Buchsen auf den Außendurchmesser der Kontaktstifte eingeengt sind. Durch diese Einengung wird das Einstecken der zugehörigen Stiftteile der Gerätesteckvorrichtung in keiner Weise behindert, jedoch das Einführen der Kontaktstifte von genormten Haushalts-Steckvorrichtungen auch unter erhöhtem Kraftaufwand sicher vermieden.This danger is further reduced by the fact that the protective sleeves of the socket parts at the front are narrowed to the outside diameter of the contact pins in the overhang area above the sockets. This constriction does not in any way hinder the insertion of the associated pin parts of the device connector, but the insertion of the contact pins of standardized household connectors is reliably avoided even with increased effort.

Durch die formschlüssige und paßgenaue Formgebung der äußeren Kontur der Berührungsschutzhülse der Buchsenkontakte mit der inneren Kontur der Berührungsschutzhülse der Stiftkontakte wird erreicht, daß nur zusammengehörige Teile der Steckvorrichtung zusammengesteckt werden können. Damit wird auch eine gefahrbringende Verwechslung mit allen international und national genormten Gerätesteckvorrichtungen ausgeschlossen.The form-fitting and precisely fitting shape of the outer contour of the protective sleeve of the socket contacts with the inner contour of the protective sleeve of the pin contacts means that only parts of the plug device that belong together can be plugged together. This also eliminates the risk of confusion with all internationally and nationally standardized device connectors.

Die formschlüssige und paßgenaue Formgebung der Kontur der Berührungsschutzhülsen zusammengehöriger Teile der Steckvorrichtung bietet weiterhin die Möglichkeit, durch Abwandlung der Formgebung abweichend von der Grundform unverwechselbare Gerätesteckvorrichtungen auszubilden, ohne die Bauart grundsätzlich verändern zu müssen. Die Unverwechselbarkeit schließt dabei ein, daß weder ein vollständiges Zusammenstekken von Steckerteilen mit abweichender Überstekkungskontur noch ein teilweises, seitlich versetztes Zusammenstecken - auch von an sich zusammengehörigen Steckerteilen - möglich ist. Erfindungsgemäß sind bis zu 40 Varianten von Gerätesteckvorrichtungen denkbar, bei denen alle oben beschriebenen Vorteile erhalten bleiben.The form-fitting and precisely fitting shape of the contour of the contact protection sleeves of associated parts of the plug-in device also offers the possibility of designing distinctive device plug-in devices by modifying the shape, without having to fundamentally change the design. The distinctiveness closes a that neither a complete assembly of connector parts with a different overlay contour nor a partial, laterally offset assembly - even of connector parts that belong together - is possible. According to the invention, up to 40 variants of device plug devices are conceivable, in which all the advantages described above are retained.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels sowie anhand der Zeichnung. Dabei zeigen:

  • Fig. 1 eine perspektivische Ansicht der beiden Teile einer dreipoligen erfindungsgemäßen Gerätesteckvorrichtung vor dem Zusammenstecken und
  • Fig. 2 einen vergrößerten Teillängsschnitt durch die Achse eines Buchsenkontakts längs der abgewinkelten Linie 11 - 11 in Fig. 1,
  • Fig. 3 Beispiele für unverwechselbare Formgebungen der Kontur von Berührungsschutzhülsen zusammengehöriger Teile der erfindungsgemäßen Gerätesteckvorrichtung.
Further advantages, features and details of the invention result from the following description of an exemplary embodiment and from the drawing. Show:
  • Fig. 1 is a perspective view of the two parts of a three-pin connector according to the invention before plugging together and
  • 2 shows an enlarged partial longitudinal section through the axis of a socket contact along the angled line 11-11 in FIG. 1,
  • Fig. 3 examples of distinctive shapes of the contour of contact protection sleeves of related parts of the device connector according to the invention.

Bei der gezeigten dreipoligen Gerätesteckvorrichtung sind am Gehäuse 1 des Stiftteils angeformte Berührungsschutzhülsen 2 für die gegenüber den Vorderkanten der Berührungsschutzhülsen zurückgesetzten Stifte 3 mit einem relativ großen Durchmesser ausgebildet, so daß sie die die Buchsenkontakte 4 eng umschließenden Berührungshülsen 5 am Buchsenteilgehäuse 6 aufnehmen können. Dabei ist der Öffnungsdurchmesser 8 der Berührungsschutzhülsen 5 im vorderen Überstandsbereich 7 über die in üblicher Weise längs geschlitzten und damit federnd die Stifte 3 aufnehmenden Buchsenkontakte 4 nahezu auf den Innendurchmesser der Buchsenkontakte 4 eingeengt, so daß insgesamt eine im wesentlichen dem Außendurchmesser der Stifte 3 entsprechende Außenöffnung 8 der Berührungsschutzhülsen 5 der Buchsenkontakte 4 vorhanden ist, die eine gefahrbringende Zusammensteckung mit anderen genormten Steckvorrichtungen sicher und zuverlässig ausschließt. Durch die paarweise abgewandelte Formgebung der Berührungsschutzhülsen (2'-5', 2"-5", 2"'-5"') zusammengehörender Steckerteile lassen sich unverwechselbare Gerätesteckvorrichtungen gleicher Bauart ausbilden, ohne die oben beschriebenen Vorteile aufzugeben.In the three-pin connector shown, molded on the housing 1 of the pin part protective sleeves 2 for the set back compared to the front edges of the protective sleeves pins 3 are formed with a relatively large diameter, so that they can accommodate the socket contacts 4 tightly surrounding contact sleeves 5 on the socket part housing 6. In this case, the opening diameter 8 of the contact protection sleeves 5 in the front protruding area 7 is narrowed almost to the inside diameter of the socket contacts 4 via the bushing contacts 4, which are longitudinally slotted and thus resiliently receiving the pins 3, so that overall an outer opening substantially corresponding to the outside diameter of the pins 3 8 of the contact protection sleeves 5 of the socket contacts 4 is present, which safely and reliably excludes a dangerous plugging together with other standardized plug devices. Due to the shape of the contact protection sleeves (2'-5 ', 2 "-5", 2 "' - 5" ') of the connector parts which are modified in pairs, distinctive device plug devices of the same type can be formed without giving up the advantages described above.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. Neben der Möglichkeit auch höherpolige Steckvorrichtungen in der erfindungsgemäßen Weise auszugestalten, könnte selbstverständlich auch die in den Figuren angedeutete Codierung der Berührungsschutzhülsen in anderer Weise erfolgen.The invention is not restricted to the exemplary embodiment shown. In addition to the possibility of also designing multi-pin plug devices in the manner according to the invention, the coding of the contact protection sleeves indicated in the figures could of course also take place in a different way.
