Dieser Netzstecker kann beispielsweise in eine Schutzkontaktsteckdose eingesteckt werden.The present invention relates to a power plug for connecting a power cord having a plurality of connecting wires. This power plug can be plugged, for example, in a safety socket.
Elektrische Steckdosen dienen zum lösbaren Anschluss elektrischer Verbraucher an ein elektrisches Versorgungsnetz. Hierbei werden die an den jeweiligen Anschlussleitungen befindlichen Stecker in die Steckdose, vorzugsweise in eine Schutzkontaktsteckdose, eingesteckt. Auch muss die Steckverbindung des Netzsteckers mit normalem Kraftaufwand wieder lösbar sein.Electrical sockets are used for the detachable connection of electrical consumers to an electrical supply network. In this case, the connectors located on the respective connecting lines are plugged into the socket, preferably in a safety socket. Also, the connector of the power plug must be releasable again with normal force.
Bei bekannten Netzsteckern besteht das Problem, dass das Steckergehäuse in erheblichem Maße über die Steckdose hervorsteht. Dies ist zum einen darin begründet, dass das Steckergehäuse sowohl als Griff zum Herausziehen des Steckers aus der Steckdose dienen zum anderen das Steckergehäuse das Netzkabel aufnimmt. Dies ist sowohl bei Netzsteckern der Fall, bei denen das Netzkabel in axialer Verlängerung der Steckerstifte aus dem Gehäuse herausgeführt wird, als auch bei Netzsteckern, bei denen das Netzkabel in rechtwinkliger Anordnung zur Anordnung der Steckerstifte aus dem Gehäuse herausgeführt wird. Im Inneren befindet sich ein Kabelanschlussbereich, in dem das in der Regel dreiadrige Netzkabel endet und dessen Anschlussdrähte mit den Steckerstiften verbunden werden. Die große Bauhöhe bedingt, dass die Anordnung dieser herkömmlichen Netzstecker im engen Spalt zwischen der Wand und der Rückwand eines Schrankes oder dergleichen Probleme bereit, die einen auf die Position des Netzsteckers begrenzten Ausschnitt der Schrankrückwand erfordern. Alternativ muss ein vergleichsweise großer Spalt in Kauf genommen werden.In known power plugs, the problem is that the connector housing protrudes to a considerable extent on the socket. This is partly due to the fact that the connector housing serve both as a handle for pulling the plug out of the socket on the other hand, the connector housing receives the power cord. This is the case both with power plugs in which the power cord is led out of the housing in the axial extension of the plug pins, as well as power plugs in which the power cord is led out of the housing in a right-angled arrangement for the arrangement of the plug pins. Inside there is a cable connection area in which the usually three-core power cable ends and its connecting wires are connected to the connector pins. The large height requires that the arrangement of these conventional power plug in the narrow gap between the wall and the rear wall of a cabinet or the like problems that require a limited to the position of the power plug neck of the cabinet rear wall. Alternatively, a comparatively large gap must be accepted.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen neuartigen Netzstecker zur Verfügung zu stellen, welcher bei herkömmlichen Netzsteckdosen, insbesondere Schutzkontaktsteckdosen, einsetzbar ist, eine besonders geringe Bauhöhe begründet sowie einen einfachen Aufbau gewährleistet.The object of the present invention is to provide a novel power plug available, which in conventional power sockets, in particular safety sockets, can be used, justifies a particularly low height and ensures a simple design.
Die vorliegende Aufgabe wird bei dem Netzstecker gemäß dem Oberbegriff des Anspruchs 1 dadurch gelöst, dass sich der Kabelanschlussbereich für die Anschlussdrähte des Netzkabels im Steckerunterteil befindet, sich der Aufnahmeraum für das Netzkabel außerhalb der äußeren Begrenzungsebene E des Rahmens der Schutzkontaktsteckdose befindet und es sich bei dem Netzkabel um ein Flachkabel handelt. Das Flachkabel begründet zum einen eine geringe Bauhöhe, zum anderen erlaubt es gleichzeitig auch eine besonders vorteilhafte Zugentlastung, insbesondere im Eintrittsbereich des Flachkabels in den Netzstecker. Der Netzstecker liegt in eingesetztem Zustand an der Außenseite des Rahmens der Steckdose an, wobei er jedoch im Vergleich zu herkömmlichen Netzsteckern eine sehr viel geringere Bauhöhe aufweist. Gleichzeitig kann hierdurch der konstruktive Aufbau des Steckers einfach gehalten werden. Dadurch, dass sich der Kabelanschlussbereich für die Anschlussdrähte des Flachkabels im Steckerunterteil befindet, kann das aus Rahmen und Deckel gebildete, das Steckerunterteil überragende Steckergehäuse besonders flach ausgebildet werden.
Insbesondere ist es konstruktiv möglich, die lichte Höhe des Aufnahmeraums, der durch das Steckergehäuse gebildet wird, an die Stärke des Flachkabels anzupassen. Diese Ausgestaltung ermöglicht es, die Innenwände von Rahmen und/oder Deckel als eben orientierte Einspannbacken für das Flachkabel zu verwenden.The present object is achieved in the power plug according to the preamble of
In particular, it is structurally possible to adapt the clear height of the receiving space, which is formed by the plug housing, to the thickness of the flat cable. This embodiment makes it possible to use the inner walls of the frame and / or cover as a flat-oriented clamping jaws for the flat cable.
Um die Montage der Anschlussdrähte des Flachkabels im Steckerunterteil zu erleichtern, sind im Bereich des Steckerunterteils quer zu dessen Längsachse Durchgangsöffnungen vorgesehen, die es erlauben mittels eines Schraubwerkzeugs, z.B. Schraubenziehers, die Schraubverbindungen im Inneren des Steckerunterteils von außen zu lösen.In order to facilitate the mounting of the connecting wires of the flat cable in the plug lower part, passage openings are provided in the region of the plug lower part transversely to the longitudinal axis thereof, which allow by means of a screwing tool, e.g. Screwdriver to loosen the screw connections inside the plug bottom part from the outside.
Zweckmäßigerweise befindet sich die Zugentlastung des Flachkabels an oder zumindest im Bereich der Austrittsöffnung des Aufnahmeraums des Steckergehäuses. Das Ende des Flachkabels kann hierbei in vorteilhafter Weise zwischen den Rahmen und den Deckel, die gleichsam als Klemmbacken wirken, eingespannt werden.Conveniently, the strain relief of the flat cable is at or at least in the region of the outlet opening of the receiving space of the plug housing. The end of the flat cable can be clamped in an advantageous manner between the frame and the lid, which act as it were as jaws.
Zweckmäßigerweis können hierbei durch die erfindungsgemäße Konstruktion die ebenen Innenwände von Rahmen und Deckel dazu benutzt werden, das Ende des Flachkabels einzuklemmen bzw. zu pressen. Die ebenen Innenwände des Rahmens sowie Deckels bewirken eine einerseits sehr wirkungsvolle, andererseits aber auch schonende Klemmung des Flachkabels im Bereich des Steckerkopfgehäuses, insbesondere im Bereich der Durchtrittsöffnung.Appropriately, the flat inner walls of the frame and lid can be used to pinch or press the end of the flat cable by the construction of the invention. The flat inner walls of the frame and cover cause a hand on the one hand very effective, but on the other hand also gentle clamping of the flat cable in the region of the plug head housing, in particular in the region of the passage opening.
Um Fixierung des Flachkabels und damit die Sicherheit gegen eine unerwünschte Zugbelastung des Flachkabels im Anschlussbereich der Kabelenden noch zu erhöhen, kann auf mindestens einer, vorzugsweise auf beiden Seiten des Steckergehäuses mindestens ein, vorzugsweise eine Mehrzahl von Anpressstegen vorhanden sein. Diese sind vorzugsweise geradlinig und in Querrichtung zum Flachkabel orientiert. Sie können vorteilhaft in die jeweilige Innenwand des Rahmens bzw. und/oder Deckels eingeformt sein.In order to increase the fixation of the flat cable and thus the security against an undesirable tensile load of the flat cable in the connection region of the cable ends, at least one, preferably on both sides of the Plug housing at least one, preferably a plurality of pressing webs to be present. These are preferably rectilinear and oriented in the transverse direction to the flat cable. They can be advantageously formed in the respective inner wall of the frame or and / or lid.
Zur Fixierung des Deckels auf dem Rahmen ist ein Verbindungsmittel, vorzugsweise eine Mehrzahl von Verbindungsmitteln, vorgesehen. Eine besondere einfache Ausgestaltung ist dadurch gekennzeichnet, dass der Deckel an dem Rahmen über insbesondere zwei Schrauben, vorzugsweise im Bereich der Austrittsöffnung des Flachkabels, befestigt ist. Hierdurch kann in vorteilhafter Weise gleichzeitig auch die Klemmung des Flachkabels bewirkt werden. Hierdurch wird vorteilhaft eine Zugentlastung gewährleistet.For fixing the lid on the frame, a connecting means, preferably a plurality of connecting means is provided. A particular simple embodiment is characterized in that the cover is attached to the frame via in particular two screws, preferably in the region of the outlet opening of the flat cable. As a result, the clamping of the flat cable can be effected in an advantageous manner at the same time. As a result, a strain relief is advantageously ensured.
Zur axialen Fixierung der Längsposition der Steckerstifte sind an der Innenseite des Deckels in das Steckerunterteil eintauchend zwei längliche Vorsprünge vorgesehen. Diese stehen an den stirnseitigen Enden der Steckerstifte an und fixieren diese in ihrer Lage in zusammengebautem Zustand des Netzsteckers. Sofern der jeweilige Vorsprung als seitlich offene Hülse ausgebildet ist, hat dies den Vorteil, dass dies gleichzeitig auch eine Führung für den jeweiligen aus dem Steckergehäuse nach unten in das Steckerunterteil geführten Anschlussdraht darstellt.For axial fixation of the longitudinal position of the plug pins, two elongated projections are provided on the inside of the lid in the plug base. These are at the front ends of the pins and fix them in position in the assembled state of the power plug. If the respective projection is designed as a laterally open sleeve, this has the advantage that this also represents a guide for the respective out of the connector housing down into the connector base connection wire.
Zwecksmäßigerweise ist der Deckel und/oder der Rahmen jeweils an dessen bzw. deren Außenseite eben ausgebildet, wodurch das Steckergehäuse, welches sich an der Außenseite des Steckdosenrahmens befindet, als sehr flacher Aufbau, vorzugsweise in Form eines rechtwinkligen oder quadratischen Kubus, oder in Scheibenform ausgebildet sein kann.
Zweckmäßigerweise liegt die Stärke des Flachkabels im Bereich von 4,0 bis 6,0 mm.Conveniently, the lid and / or the frame are each formed flat on the outside thereof, whereby the plug housing, which is located on the outside of the socket frame, designed as a very flat structure, preferably in the form of a rectangular or square cube, or in disc shape can be.
Conveniently, the thickness of the flat cable is in the range of 4.0 to 6.0 mm.
Die Stärke des Deckels einschließlich des Rahmens, also des Steckergehäuses, liegt im Bereich von 6,0 bis 9,0 mm, vorzugsweise im Bereich von 7,0 bis 8,0 mm. Der erfindungsgemäße Netzstecker besitzt demzufolge eine äußerst geringe Bauchhöhe außerhalb des Rahmens einer Netzsteckdose.The thickness of the lid including the frame, so the plug housing, is in the range of 6.0 to 9.0 mm, preferably in the range of 7.0 to 8.0 mm. The power plug according to the invention therefore has an extremely low abdominal height outside the scope of a power outlet.
Zweckmäßigerweise dient der äußere Umfang des Steckergehäuses als Handgriff zum Herausziehen des Netzsteckers. Hierzu steht dieser vorzugsweise seitlich über den Aufnahmeschacht der Netzsteckdose über.Conveniently, the outer circumference of the plug housing serves as a handle for pulling out the power plug. For this purpose, this is preferably laterally over the receiving shaft of the power outlet over.
Auch kann vorgesehen sein, dass der Rahmen zumindest über einen Teil seines Umfang, vorzugsweise entlang seines gesamten Umfangs, ein von der Außenkante zum Steckerunterteil hin orientierte Abschrägung aufweist. Dies ermöglicht es, das Steckergehäuse im eingesteckten Zustand des Netzsteckers mit den Fingern zu hintergreifen, so dass der Netzstecker in einfacher Weise aus der Steckdose herausgezogen werden kann.It can also be provided that the frame has, at least over part of its circumference, preferably along its entire circumference, a chamfer oriented from the outer edge to the plug lower part. This makes it possible to engage behind the plug housing in the inserted state of the power plug with your fingers, so that the power plug can be easily pulled out of the socket.
Zweckmäßigerweise weißt der erfindungsgemäße Netzstecker eine Ausziehhilfe auf, die von einer eingefahrenen Position in eine ausgefahrene Position bringbar ist, in der die Ausziehhilfe das Ziehen des Netzsteckers erleichtert.Conveniently, the power plug according to the invention has a pull-out on, which can be brought from a retracted position to an extended position in which the extension aid facilitates pulling the power plug.
Das Ausfahren der Ausziehhilfe ist zweckmäßigerweise durch eine Federvorspannung vorgesehen. Die Ausziehhilfe kann in der eingefahrenen Position mittels Verrastmittel, die handbetätigt gelöst werden können, in Position gehalten werden.The extension of the pull-out is expediently provided by a spring preload. The extension aid can be held in position in the retracted position by means of latching means which can be released manually.
