Abstract

In order to connect small electric apparatus having for example a two-pin configuration or a European flat plug into any of the international standard plugging systems according to need, a handy pentaprism-shaped connector has on its sides plug pin arrangements (2) for five different plugging systems and contains a revolving body (4, 7) which has in the area of the top and/or bottom surface of the connector sockets for two more plugging systems. These can be manually snapped (8, 9) into contact (3, 5, 6) with the plug pin arrangement (2) of the connector needed at any time, the remaining plug pins being then absolutely deprived of any voltage.

Description

Die Erfindung bezieht sich auf ein elektrisches Verbindungsstück in Form eines Adapters, um damit beispielsweise auf Auslandsreisen die mit den im jeweiligen Heimatland gebräuchlichen Netzsteckern ausgerüsteten Elektro(klein-)geräte ohne Schutzkontakt nach Art eines Zwischensteckners auch an den in anderen Ländern und Erdteilen vorhandenen Steckdosen benutzen zu können.The invention relates to an electrical connector in the form of an adapter so that, for example, when traveling abroad, the (small) devices equipped with the power plugs used in the respective home country without protective contact in the manner of an adapter can also be used on the sockets present in other countries and continents to be able to.

Für diesen Zweck sind sogenannte Reisesteckersets bekannt, die aus mehreren Zwischensteckern bestehen, von denen jeder einzelne nur für die Anpassung des einheimischen Stecksystems an ein bestimmtes andere geeignet ist. Da einem Benutzer häufig nicht bekannt ist, welches besondere Stecksystem in einem anderen Land verwendet wird, und er demgemäß stets mehrere Zwischenstecker lose wie leicht verlierbar mit sich führen muß, hat sich diese Ausführung nicht bewährt. Des weiteren hat man bereits versucht, ein und denselben Zwischenstecker mittels einer Schiebemechanik und durch Herausdrehen einzelner Steckerstifte für mehrere unterschiedliche Stecksysteme verwendbar auszubilden. Diese Ausführung ist jedoch reichlich kompliziert und von einem Nichtfachmann selbst unter Zuhilfenahme der Bedienungsanleitung im allgemeinen kaum sachgerecht und sicher zu handhaben.For this purpose, so-called travel plug sets are known, which consist of several intermediate plugs, each of which is only suitable for adapting the local plug system to a specific other. Since a user is often not aware of which special plug-in system is used in another country, and consequently he always has to carry several adapter plugs loose as easily as lost, this design has not proven itself. Furthermore, attempts have already been made to design one and the same adapter plug by means of a sliding mechanism and by unscrewing individual plug pins for several different plug systems. However, this version is extremely complicated and can hardly be handled properly and safely by a non-specialist even with the aid of the operating instructions.

In Anbetracht dessen liegt der Erfindung die Aufgabe zugrunde, ein elektrisches Verbindungsstück zu entwickeln, durch welches sich die weltweit vorhandenen Stecksysteme praktikabel und gefährdungssicher auf die Stromentnahmemöglichkeit aus einem bestimmten Steckdosentyp umrüsten lassen. Dabei soll es sich um einen kompakten Gebrauchsgegenstand handeln, der keinerlei manuellen Eingriff in sein Kontaktsystem zuläßt und bei Benutzung vollends berührungssicher dasteht.In view of this, the object of the invention is to develop an electrical connecting piece by means of which the plug systems available worldwide can be converted practically and in a manner that is safe from hazards to the possibility of drawing current from a specific type of socket. It is supposed to be a compact article of daily use that does not allow any manual intervention in its contact system and is completely safe to touch when in use.

Diese Aufgabe wird bei einem elektrischen Verbindungsstück nach dem Oberbegriff des Patentanspruchs 1 durch die in dessen Kennzeichenteil angegebenen Merkmale gelöst. In einer derartigen Ausführung stellt sich das erfindungsgemäße Verbindungsstück vorteilhafterweise als ein handliches Zubehörteil dar, welches sich je nach Art des an Ort und Stelle vorhandenen Stecksystems mit der entsprechenden Steckerstiftanordnung in eine der festinstallierten Steckdosen oder ggf. auch in ein fliegendes Kupplungsstück einstecken läßt, um nach dem Verstellen des markierten Drehkörpers in Richtung der Entnahmestelle die in denselben einbezogene heimatliche Steckdose für den Anschluß eines mitgeführten Elektrogeräts benutzen zu können. Darüber hinaus bewirkt der von dem Verbindungsstück beinhaltete Stecksystemwähler über einen mitunter nützlichen Ein- und Ausschalteffekt, daß die jeweils unbenutzt frei stehenden Steckerstiftanordnungen nach außen hin absolut spannungsfrei dastehen.This object is achieved in an electrical connector according to the preamble of claim 1 by the features specified in its characterizing part. In such an embodiment, the connector according to the invention advantageously presents itself as a handy accessory which, depending on the type of plug system present on site, can be inserted with the corresponding plug pin arrangement into one of the permanently installed sockets or possibly also into a flying coupling piece, in order to the adjustment of the marked rotating body in the direction of the tapping point to be able to use the domestic socket included in the same for the connection of an electrical device carried along. In addition, the plug-in system selector contained in the connector, via a switch-on and switch-off effect which is sometimes useful, ensures that the plug connector arrangements which are in each case unused stand out from the outside absolutely free of tension.

Desgleichen kann der Steckerkörper für einen begrenzteren Anwendungsbereich des Verbindungsstücks und nur drei oder vier Steckerstiftanordnungen in seiner geometrischen Raumform mit den selben Vorteilen tri- oder tetragonal-prismatisch ausgebildet sein, bzw. die an seiner Deck- und/oder Grundfläche vorgesehenen verstellbaren Steckdosen ihrem System nach übereinstimmend oder auch unterschiedlich ausgelegt werden, ohne dadurch aus dem Schutzumfang der Erfindung zu gelangen.Likewise, the connector body for a more limited area of application of the connecting piece and only three or four connector pin arrangements can be designed in its geometrical three-dimensional form with the same advantages as tri-or tetragonal-prismatic, or the adjustable sockets provided on its top and / or base surface according to their system can be interpreted in the same way or differently without thereby falling outside the scope of the invention.

Das Merkmal des Anspruchs 2 richtet sich auf die zweckmäßige Ausbildung der beweglichen Anschluß- und Kontaktteile des Verbindungsstücks. Demgemäß bestehen die beiden unterhalb der jeweils vorhandenen Einstecköffnungen eingesetzten und mittels angeformter Stegansätze an dem Drehkörper gehalterten Buchsenkontaktstücke gleicherweise aus einem Langgestreckt U-förmig gefalteten Messingblechstreifen. Dabei sind die parallel verlaufenden und über den stegartig reduzierten Querschenkel miteinander verbundenen Längsschenkel dieser Buchsenkontaktstücke gegeneinander eingewölbt und jeweils in sich mit zwei gegenüberliegenden Querschlitzungen versehen. Auf diese Weise bilden sich drei voneinander unabhängige Einsteckbereiche, die es ermöglichen, beispielsweise von der einen Seite her in der Mitte ein Steckerpaar und gleichzeitig neben diesem von der anderen Seite her zwei weitere Steckerpaare eigenständig gefedert in sich aufzunehmen. Des weiteren setzen sich die äußeren Längsschenkel der Buchsenkontaktstücke über eine Ausstanzung jeweils in schräg nach vorne vorstehende Schleifkontaktarme fort, die im montierten Zustand des Verbindungsstücks unter Federspannung mit den an der Innenwandung der hohlzylinderförmigen Durchbrechung des Steckerkörpers auf einer Kreisbahn gelegenen Festkontaktstücken der verschiedenen Steckerstiftanordnungen je nach Einstellung in leitende Berührung gelangen.The feature of claim 2 is directed to the appropriate design of the movable connection and contact parts of the connector. Accordingly, the two socket contact pieces inserted underneath the respective plug-in openings and held on the rotating body by means of integrally formed web attachments likewise consist of an elongated, U-shaped folded sheet brass strip. The parallel longitudinal legs of these socket contact pieces, which are connected to one another via the web-like reduced cross leg, are arched against one another and each provided with two opposite transverse slots. In this way, three mutually independent plug-in areas are formed, which make it possible, for example, to accommodate a pair of plugs in the middle from one side and, at the same time, to independently accommodate two further pairs of plugs next to it from the other side. Furthermore, the outer longitudinal legs of the socket contact pieces are continued via a punched-out section in protruding sliding contact arms which, in the assembled state of the connecting piece under spring tension, with the fixed contact pieces of the various plug pin arrangements located on a circular path on the inner wall of the hollow body of the plug body, depending on the setting come into contact with one another.

Um die verschiedenen Kontaktpositionen an dem Verbindungsstück mechanisch sicherzustellen, ist nach dem Merkmal des Anspruchs 3 vorgesehen, daß der auf mindestens einer Außenseite mit einer um die Steckereinführungsausnehmung hochgezogenen Griffumrandung versehene Drehkörper innerhalb eines ringförmigen Hohlraums derselben über eine den vorhandenen Steckerstiftanordnungen entsprechende Anzahl von Rastnocken verfügt, die in jeder Kontaktposition des Drehkörpers und seiner Steckdose(n) auf Seiten des Steckerkörpers gleichzeitig drei von diesem an funktionell korrespondierender Stelle hochgezogen angeformte Raststege federnd hintergreifen. Auf diese Weise ist gewährleistet, daß der Drehkörper deutlich fühlbar in der benötigten Kontaktposition einrastet, wobei dieselbe zudem durch eine auf die gewählte Steckerstiftanordnung hinweisende Sichtmarke an der Griffumrandung angezeigt wird.In order to mechanically ensure the different contact positions on the connecting piece, it is provided according to the feature of claim 3 that the rotating body provided on at least one outside with a handle border drawn up around the plug insertion recess has a number of locking cams corresponding to the existing plug pin arrangements within an annular cavity thereof, which in each contact position of the rotating body and its socket (s) on the side of the plug body simultaneously grip three latching webs which are molded up and pulled up at a functionally corresponding point. In this way it is ensured that the rotating body engages clearly in the required contact position, whereby the same is also indicated by a visual mark on the handle border indicating the selected pin arrangement.

Gemäß dem Merkmal des Anspruchs 4 ist der Drehkörper dazu ausgebildet, die vorhandenen Steckerstiftanordnungen des Steckerkörpers auf der einen oder auf den beiden steckerfreien Seiten des Verbindungsstücks mit einer Steckdose bzw. mit zwei Steckdosen des gleichen Systems oder auch unterschiedlicher Systeme zu verbinden. Hierfür setzt sich der Drehkörper aus zwei beiderseits innerhalb des Steckerkörpers beweglich geführten Formteilen aus Isolierstoff zusammen, die beispielsweise mittels zweier sich im Randungsbereich zwischen den Buchsenkontaktstücken gegenüberliegender Stützstege formschlüssig ineinandergreifen, während ein dritter, zentral angeformter Steg die Verschraubung der Formteile im Zuge der Montage von außen her ermöglicht. Dabei ist z. B. eines der Formteile in sich mit zwei Einstecköffnungen für einen Konturen- oder auch Schutzkontaktstecker versehen, während das andere Formteil vier paarweise dazu parallel gelegene Einstecköffnungen für das Einsetzen von zwei Europa-Flachsteckern aufweisen kann. Andererseits ist es ebenfalls möglich, eines der genannten Formteile gegen eine entsprechend ausgebildete Abdeckplatte auszutauschen, wenn für eine zweite Steckdosenanordnung kein Bedarf bestehen sollte.According to the feature of claim 4, the rotating body is designed to connect the existing plug pin arrangements of the plug body on one or on the two plug-free sides of the connector with a socket or with two sockets of the same system or different systems. For this purpose, the rotating body is composed of two molded parts made of insulating material that are movably guided on both sides within the plug body, which interlock, for example, by means of two supporting webs located opposite each other in the edge area between the socket contact pieces, while a third, integrally molded web, the screwing of the molded parts in the course of assembly from the outside here. Here is z. B. one of the molded parts with two insertion openings for a contour or protective plug, while the other molded part can have four pairs of parallel insertion openings for the insertion of two European flat plugs. On the other hand, it is also possible to replace one of the moldings mentioned above with a correspondingly designed cover plate if there is no need for a second socket arrangement.

Als Ausführungsbeispiel der Erfindung ist in der anliegenden Zeichnung ein elektrisches Verbindungsstück dargestellt, welches den Anschluß eines mit einem 2-poligen Konturen-oder Europastecker ohne Schutzkontakt ausgerüsteten Elektrogeräts an alle international standardisierten Stecksysteme ermöglicht. Dabei zeigt:

  • Fig. 1 die Draufsicht auf die Deckfläche des Verbindungsstücks mit der Steckdose für den Konturenstecker,
  • Fig. 2 die Ansicht der Grundfläche mit den Steckdosen für zwei Europa-Flachstecker, und
  • Fig. 3 das Verbindungsstück gemäß der Darstellung in Fig. 1 mit abgenommenem Drehkörper-Formteil.
As an exemplary embodiment of the invention, an electrical connecting piece is shown in the accompanying drawing, which enables the connection of an electrical device equipped with a 2-pole contour or European plug without a protective contact to all internationally standardized plug-in systems. It shows:
  • 1 is a plan view of the top surface of the connector with the socket for the contour plug,
  • Fig. 2 shows the view of the base with the sockets for two European flat plugs, and
  • Fig. 3 shows the connector as shown in Fig. 1 with the rotary body molding removed.

Wie aus den Darstellungen hervorgeht, besitzt der Steckerkörper (1) des Verbindungsstücks geometrisch gesehen die Form eines geraden fünfseitigen Prismas und weist innerhalb seines Zentralbereichs eine von der Deckfläche zur Grundfläche hin durchgehende zylindrische Ausnehmung auf. In jede der fünf Seitenflächen des Steckerkörpers (1) ist eine der unterschiedlichen Steckerstiftanordnungen (2) fest eingelassen, deren Polkontaktanschlüsse jeweils an der Innenwandung der zylindrischen Ausnehmung auf einer Kreisbahn in Festkontaktstücke (3) auslaufen.As can be seen from the illustrations, the connector body (1) of the connecting piece has the shape of a straight, five-sided prism from a geometric point of view and has a cylindrical recess extending from the top surface to the base surface within its central region. In each of the five side surfaces of the plug body (1) one of the different plug pin arrangements (2) is permanently embedded, the pole contact connections of which run out on the inner wall of the cylindrical recess on a circular path in fixed contact pieces (3).

Des weiteren ist aus Fig. 3 der Zeichnung ersichtlich, daß die auf dem die Grundfläche des Verbindungsstücks bildenden Formteil (4) eines Drehkörpers an den vier Einstecköffnungen für die Steckerstifte von zwei Europasteckern mittels angeformter Stegansätze gehalterten beiden Buchsenkontaktstücke (5) U-förmig ausgebildet und in sich 3-fach unterteilt und hinzu an ihren äußeren Längsschenkeln mit abgewinkelt vorstehenden Schleifkontaktarmen (6) versehen sind, die jeweils im gleichen Abstand mit demjenigen Paar der vorgenannten Festkontaktstücke (3) einer der Steckerstiftanordnungen (2) in leitende Berührung gelangen, auf welches der Drehkörper mit Hilfe des die Deckfläche des Verbindungsstücks bildenden, für die Darstellung in Fig. 3 deutlichkeitshalber entfernten Formteils (7) von Hand eingestellt worden ist. Hierfür ist das in sich mit zwei Einstecköffnungen für die Steckerstifte eines Konturensteckers versehene Formteil (7) des Drehkörpers zugleich mit einer (pfeil-)markierten Griffumrandung (8) versehen, unter welcher sich die in Fig. 1 der Zeichnung im Teilschnitt dargestellte Rastvorkehrung (9) im Zusammenwirken mit dem Steckerkörper (1) befindet.Furthermore, it can be seen from Fig. 3 of the drawing that the two socket contact pieces (5), which are held on the base part of the connecting piece forming part (4) of a rotating body at the four insertion openings for the plug pins of two European plugs by means of integrally formed web approaches, and divided into 3 parts and additionally provided on their outer longitudinal legs with angled protruding sliding contact arms (6), each of which comes into conductive contact at the same distance with that pair of the aforementioned fixed contact pieces (3) of one of the plug pin arrangements (2) on which the The rotating body has been set by hand using the molded part (7) which forms the cover surface of the connecting piece and has been removed for the sake of clarity in FIG. 3. For this purpose, the molded part (7) of the rotating body, which is provided with two insertion openings for the plug pins of a contour plug, is at the same time provided with an (arrow) marked grip border (8), under which the locking arrangement (9 ) is in interaction with the connector body (1).

Demgemäß ist der zeichnerischen Darstellung ohne weitere Hinweise zu entnehmen, daß sich die hier nur beispielhaft dargebotene Zusammenstellung der verschiedenen Steckerstift- und Buchsenkontaktelemente (2, 5) je nach nationalem Bedarf variieren läßt und das Verbindungsstück aufgrund seiner konstruktiven Ausbildung noch darüber hinaus die Einbeziehung eines weiteren Kontaktelements, z. B. eines zusätzlichen Schutzkontakts, ermöglicht.Accordingly, it can be seen from the graphic representation without further information that the combination of the various plug and socket contact elements (2, 5) presented here only as an example can be varied depending on national requirements and that the connector, due to its constructive design, also includes the inclusion of another Contact element, e.g. B. an additional protective contact.
