Description

Die Erfindung betrifft einen Netzstecker zum Anschluss eines Netzkabels an eine Schutzkontaktsteckdose, gemäß Anspruch 1.The invention relates to a power plug for connecting a power cord to a grounded power outlet, according to claim 1.

Netzstecker der hier betrachteten Art sind unter der Bezeichnung Konturenstecker oder bei Fehlen eines Schutzkontaktes als Eurostecker bekannt. Mit ihnen können Geräte der Schutzklasse I und der Klasse II an das Stromnetz angeschlossen werden. Die Stecker sind wieder anschließbar, oder bei der nicht wieder anschließbaren Ausführung voll mit Kunststoff umspritzt. Typische Anwendungsgebiete der Stecker sind Geräte, wie beispielsweise Radios, Lampen, Staubsauger u. dgl.Power plugs of the type considered here are known as contour plugs or in the absence of a protective contact as a Euro plug. They can be used to connect devices of protection class I and class II to the mains. The plugs can be reconnected, or fully encapsulated with plastic in the non-re-connectable version. Typical applications of the plug are devices such as radios, lamps, vacuum cleaners u. like.

Bei den bekannten Netzsteckern ist das Kabel überwiegend rechtwinklig zur Anordnung der Steckerstifte aus dem Gehäuse herausgeführt (sog. Winkelstecker). Diese weisen an ihrem Übergang zwischen Gehäuse und Kabel einen Knickschutz auf, der das Kabel vor Beschädigungen schützen soll.In the known power plugs, the cable is led out at right angles to the arrangement of the connector pins out of the housing (so-called angular connector). These have a bend protection at their transition between the housing and the cable, which is intended to protect the cable from damage.

EP 1691456 offenbart einen Netzstecher gemäß Oberbegriff des Anspruch 1. EP 1691456 discloses a netting pier according to the preamble of claim 1.

Die bekannten Netzstecker werden häufig am Kabel aus der Steckdose herausgezogen. Dadurch wirkt eine sehr hohe Kraft auf das Kabel, was trotz des Knickschutzes zu Beschädigungen innerhalb des Steckers führen kann. Solche Beschädigungen sind oftmals von außen nicht sichtbar und können bei einem Wiedereinstecken des Steckers in die Steckdose zu einer Gefahr werden, beispielsweise durch Kurzschlüsse o. dgl.The known power plug are often pulled out of the socket on the cable. As a result, a very high force acts on the cable, which, in spite of the anti-kink protection, can lead to damage within the connector. Such damage is often not visible from the outside and can be a re-insertion of the plug into the socket to a risk, for example by short circuits o. The like.

Zur Vermeidung dieses Problems ist es aus der DE 10 2006 029 927 A1 bekannt, in einem Netzstecker einen Hebel vorzusehen, der bei einem Herausziehen des Steckers am Kabel ein Herausdrücken des Steckers aus der Steckdose bewirkt. Nachteilig an dem bekannten Netzstecker ist jedoch, dass sich der Hebel zwischen den Steckerstiften des Steckers befindet und auch dort bei einem Ziehen am Kabel aus dem Stecker heraustritt und auf dem Boden der Steckdose abstützt. Dadurch bedingt ist der bekannte Netzstecker lediglich bei Anwendungen einsetzbar, bei denen keine funktionswichtigen Teile, wie beispielsweise ein Schutzkontakt, im Bereich zwischen den Steckerstiften angeordnet sind. Zudem wirkt der bekannte Netzstecker nicht dem Problem entgegen, dass es insbesondere für ältere Menschen oft schwierig ist, bei bestimmungsgemäßem Herausziehen des Steckers eine ausreichende Kraft aufzubringen, um den Stecker aus der Steckdose herausziehen zu können sitzen, da die Stecker sehr stramm in den Steckdosen gehalten sind. Eine Unterstützung der Ausziehbewegung findet lediglich bei unsachgemäßem Herausziehen des Steckers am Kabel statt.To avoid this problem it is from the DE 10 2006 029 927 A1 known to provide a lever in a power plug, which causes a withdrawal of the plug on the cable pushing out of the plug from the socket. A disadvantage of the known power plug, however, is that the lever is located between the plug pins of the plug and also there emerges when pulling on the cable from the plug and supported on the floor of the socket. As a result, the known power plug is only used in applications in which no functionally important parts, such as a protective contact, are arranged in the region between the plug pins. In addition, the known power plug does not counteract the problem that it is often difficult, especially for the elderly, to apply sufficient force when properly pulling out the plug to pull the plug out of the socket can sit because the plug very tightly held in the sockets are. A support of the pull-out takes place only with improper pulling out of the plug on the cable.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zu Grunde, Netzstecker der hier betrachteten Art derart weiterzubilden, dass auch bei einem Herausziehen des Steckers am Kabel eine Beschädigung verhindert ist und gleichzeitig die aufzuwendende Kraft zum Herausziehen des Steckers aus der Steckdose reduziert ist. Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, dass der Grundkörper schwenkbar an dem Steckergehäuse angeordnet ist, und dass das Steckergehäuse einen Ausleger aufweist, der sich außerhalb der Steckdosenvertiefung der Schutzkontaktsteckdose abstützt.The invention aims to remedy this situation. The invention is based on the object, power plug of the type considered here such that even when pulling out the plug on the cable damage is prevented and at the same time the expended force is reduced to pull out the plug from the socket. According to the invention, this object is achieved in that the main body is pivotally mounted on the plug housing, and that the plug housing has a boom which is supported outside the socket recess of the grounded receptacle.

Mit der Erfindung ist ein Netzstecker zum Anschluss eines Netzkabels an eine Schutzkontaktsteckdose geschaffen, die im Falle eines Herausziehens des Steckers am Kabel eine Beschädigung des Steckers verhindert. Dies ist dadurch bewirkt, dass der Grundkörper schwenkbar an dem Gehäuse angeordnet ist. Hierdurch gibt der Stecker im Falle eines Ziehens an dem Kabel in im Wesentlichen axialer Richtung der Steckerstifte nach, wodurch einer Überbeanspruchung der Verbindung zwischen Netzkabel und Stecker entgegengewirkt ist. Gleichzeitig stützt sich bei einem solchen Ziehen an dem Kabel der Ausleger außerhalb der Steckdosenvertiefung ab, wodurch die Zugbewegung zusätzlich unterstützt ist, was einer Beschädigung der Verbindung zwischen Netzkabel und Stecker zusätzlich entgegenwirkt. Zudem ist durch die Schwenkbarkeit des Steckergehäuses zum Steckerteil und die Möglichkeit eines Abstützens des an dem Gehäuse vorgesehenen Auslegers auch bei bestimmungsgemäßem Herausziehen des Steckers aus der Steckdose die aufzuwendende Kraft deutlich reduziert. Hierdurch ist insbesondere älteren Menschen das Herausziehen der Stecker aus der Steckdose wesentlich erfeichtert. Des Weiteren ist durch den an dem Gehäuse vorgesehenen Ausleger der Steckbereich des Netzsteckers zu den genormten Steckern unverändert, sodass der erfindungsgemäße Stecker für alle bekannten Netzsteckervarianten verwendbar ist.With the invention, a power plug for connecting a power cord is provided to a safety socket, which prevents damage to the plug in the event of withdrawal of the plug on the cable. This is effected by the base body being pivotally mounted on the housing. As a result, in the case of pulling on the cable, the plug yields in the substantially axial direction of the plug pins, which counteracts an overuse of the connection between the power cord and the plug. At the same time relies on such a pulling on the cable, the boom outside the socket recess, whereby the pulling movement is additionally supported, which additionally counteracts damage to the connection between the power cord and plug. In addition, the expended force is significantly reduced by the pivoting of the plug housing to the plug part and the possibility of supporting the boom provided on the housing even when properly pulled out of the plug from the socket. As a result, the removal of the plug from the socket is particularly erfeichtert especially elderly people. Furthermore, the insertion area of the power plug to the standardized plugs is unchanged by the boom provided on the housing, so that the plug according to the invention can be used for all known power plug variants.

In Weiterbildung der Erfindung erfolgt die Schwenkbarkeit über Lagerbolzen, die in dem Gehäuse und dem Grundkörper gelagert sind. Die Verwendung von Lagerbolzen stellt dabei eine einfache und zugleich zuverlässige Art der Schwenkbarkeit zur Verfügung.In a further development of the invention, the pivoting takes place via bearing bolts which are mounted in the housing and the base body. The use of bearing bolts provides a simple and reliable way of pivoting available.

In anderer Weiterbildung der Erfindung ist der Grundkörper lösbar an dem Gehäuse angeordnet. Dies ermöglicht ein Umrüsten des Netzsteckers, wodurch auf die jeweiligen nationalen Besonderheiten bei der Herstellung der Stecker Rücksicht genommen werden kann. Durch diese Maßnahme ist in Folge dessen eine hohe Flexibilität bei der Herstellung von Netzsteckern für verschiedene Länder hervorgerufen.In another embodiment of the invention, the base body is detachably arranged on the housing. This allows a conversion of the power plug, which can be taken into account for the respective national characteristics in the production of the plug. As a result of this measure, a high flexibility in the production of power plugs for different countries is caused.

Der als Ausführungsbeispiel gewählte Netzstecker 1 zum Anschluss eines Netzkabels 2 an eine Schutzkontaktsteckdose 3 besteht aus einem Steckerteil 4 und einem Steckergehäuse 5. In dem Steckerteil 4 sind Steckerstifte 6 angeordnet. Der Netzstecker 1 umfasst einen Kabelanschlussraum 7, der mit dem Steckerteil 4 verbunden ist.The selected as an embodiment power plug 1 for connecting a power cord 2 to a safety socket 3 consists of a plug part 4 and a plug housing 5. In the plug part 4 plug pins 6 are arranged. The power plug 1 comprises a cable connection space 7, which is connected to the plug part 4.

Das Steckerteil 4 besteht aus einem Grundkörper 41. Der Grundkörper 41 hat die Kontur eines üblichen Eurosteckers und taucht bei bestimmungsgemäßem Gebrauch des Netzsteckers 1 in die in der Schutzkontaktsteckdose 3 vorgesehene Steckdosenvertiefung 31 ein. Der Grundkörper 41 ist von den Steckerstiften 6 durchsetzt, die auf der dem Steckergehäuse 5 abgewandten Seite aus dem Grundkörper 41 hervortreten. Zwischen den Steckerstiften 6 ist in dem Grundkörper 41 ein Niet 42 parallel zu den Steckerstiften 6 angeordnet. Weiterhin ist in dem Grundkörper 41 in ansich bekannter Weise ein Schutzkontakt 43 vorgesehen.The male part 4 consists of a main body 41. The main body 41 has the contour of a conventional Euro plug and emerges when used as intended the power plug 1 in the provided in the socket 3 socket outlet 31 a. The main body 41 is penetrated by the connector pins 6, which protrude from the main body 41 on the side facing away from the connector housing 5. Between the connector pins 6, a rivet 42 is arranged parallel to the connector pins 6 in the base body 41. Furthermore, a protective contact 43 is provided in the base body 41 in a known manner.

Das Steckerteil 4 weist zudem in bekannter Weise auf seinem Umfang Schlitze 44 auf, die zum Durchtritt des Schutzkontakts 43 dienen. Ebenso sind - um 90 Grad zu den Schlitzen 44 versetzt - Führungen 45 auf dem Umfang des Steckerteils 4 vorgesehen, die beim Einstecken in die Steckdose 3 mit dort angeordneten Führungen korrespondieren. Darüber hinaus sind auf dem Umfang des Steckerteils 4 benachbart zu den Führungen 45 Bohrungen 46 angeordnet, die rechtwinklig zur Längsmittellinie der Steckerstifte 6 ausgerichtet sind. In dem dem Steckergehäuse 5 zugewandten Bereich ist auf der dem Netzkabel 2 abgewandten Seite an dem Steckerteil 4 ein Absatz 47 ausgebildet, der einen im Vergleich zum Grundkörper 41 kleineren Durchmesser aufweist.The plug part 4 also has in a known manner on its periphery slots 44, which serve for the passage of the protective contact 43. Similarly, - offset by 90 degrees to the slots 44 - guides 45 are provided on the circumference of the plug part 4, which when plugged into the socket 3 with guides arranged there correspond. In addition, 45 holes 46 are arranged on the circumference of the plug part 4 adjacent to the guides, which are aligned at right angles to the longitudinal center line of the plug pins 6. In the region facing the plug housing 5, a shoulder 47 is formed on the side facing away from the power cable 2 on the plug part 4, which has a smaller diameter compared to the main body 41.

Das Steckergehäuse 5 weist eine Basis 51 auf, an deren einen Ende der Kabelanschlussraum 7 vorgesehen ist. Die Basis 51 ist mit einem Deckel 52 verschlossen. Zwischen Basis 51 und Deckel 52 ist ein Hohlraum hervorgerufen, durch den die Verbindung des Netzkabels 2 mit den Steckerstiften 6 erfolgt. An der Basis 51 ist im Bereich des Steckerteils 4 eine Lageraufnahme 53 angeordnet, die aus zwei im Wesentlichen halbkreisförmigen Wangen 54 besteht. Die Wangen 54 weisen Löcher 55 auf, die in montiertem Zustand mit den Bohrungen 46 im Steckerteil 4 fluchten. Die Verbindung zwischen Steckerteil 4 und Steckergehäuse 5 erfolgt mit Hilfe von Lagerbolzen 56, die durch die Löcher 55 in die Bohrungen 46 eingeführt sind. Die Wangen 54 sind Bestandteil eines umlaufenden Randes 57, der an der Basis 51 angeordnet ist. Der Rand 57 korrespondiert mit dem Absatz 47 des Steckerteils 4.The plug housing 5 has a base 51, at one end of the cable connection space 7 is provided. The base 51 is closed by a lid 52. Between base 51 and lid 52, a cavity is caused, through which the connection of the power cable 2 takes place with the connector pins 6. At the base 51, a bearing receptacle 53 is arranged in the region of the plug part 4, which consists of two substantially semicircular cheeks 54. The cheeks 54 have holes 55 which are aligned in the assembled state with the holes 46 in the plug part 4. The connection between the plug part 4 and connector housing 5 by means of bearing bolts 56 which are inserted through the holes 55 in the holes 46. The cheeks 54 are part of a peripheral edge 57, which is arranged on the base 51. The edge 57 corresponds to the shoulder 47 of the plug part 4.

Das Steckergehäuse 5 weist auf seiner dem Netzkabel 2 abgewandten Seite einen Ausleger 58 auf, der über das Steckerteil 4 hinausragt. Im Ausführungsbeispiel ist der Ausleger 58 in einfacher Weise durch eine Verlängerung der Basis 51 hervorgerufen. Der Ausleger 58 stützt sich in eingestecktem Zustand des Steckers 1 in die Steckdose 3 in einem Bereich außerhalb der Steckdosenvertiefung 31 ab; im Ausführungsbeispiel stützt sich der Ausleger 58 an dem Rahmen 32 der Steckdose 3 ab.The plug housing 5 has on its side facing away from the power cable 2 a boom 58 which projects beyond the plug part 4. In the exemplary embodiment, the boom 58 is caused in a simple manner by an extension of the base 51. The boom 58 is supported in the inserted state of the plug 1 in the socket 3 in an area outside the socket recess 31 from; In the exemplary embodiment, the boom 58 is supported on the frame 32 of the socket 3.

In eingestecktem Zustand des Netzsteckers 1 in die Steckdose 3 (Fig. 4) taucht das Steckerteil 4 in die Steckdosenvertiefung 31 ein. Dabei liegt die Basis 51 auf dem Rahmen 31 der Steckdose 3 bereichsweise auf. Zum Herausziehen des Netzsteckers 1 aus der Steckdose 3 fasst der jeweilige Benutzer bei bestimmungsgemäßem Herausziehen das Steckergehäuse 5 im Bereich zwischen Steckerteil 4 und Kabelanschlussraum 7 oder am Kabelanschlussraum 7 selbst und führt eine zur Ausrichtung der Steckerstifte 6 im Wesentlichen parallele Bewegung aus. Diese Bewegung führt zu einer Schwenkung des Steckergehäuses 5 im Verhältnis zum Steckerteil 4 um die von den Lagerbolzen 56 gebildete Schwenkachse. Aufgrund des Absatzes 47 ist diese Schwenkbewegung auch nicht durch den Rand 57 behindert.In plugged state of the power plug 1 into the socket 3 ( Fig. 4 ) plugs the plug part 4 in the socket recess 31 a. In this case, the base 51 is located on the frame 31 of the socket 3 in some areas. To pull out the power plug 1 from the socket 3 summarizes the respective user in accordance with regulations Pulling out the connector housing 5 in the area between the plug part 4 and the cable connection space 7 or on the cable connection space 7 itself and performs a for the alignment of the connector pins 6 substantially parallel movement. This movement leads to a pivoting of the plug housing 5 in relation to the plug part 4 about the pivot axis formed by the bearing pin 56. Due to the paragraph 47, this pivoting movement is not hindered by the edge 57.

Da die Schwenkachse zwischen Steckerteil 4 und Steckergehäuse 5 auf der Verlängerung der Längsachse der Steckerstifte 6 angeordnet ist und der Ausleger 58 auf der dem Angriffspunkt des Benutzers abgewandten Seite der Lagerachse vorgesehen ist, führt die Schwenkung um die Lagerachse zu einem Abstützeffekt des Auslegers 58 außerhalb der Steckdosenvertiefung 31, im Ausführungsbeispiel an dem Rahmen 32. Da der Ausleger 58 den äußersten Punkt des Steckergehäuses 5 darstellt, führt das Steckergehäuse 5 auch im Bereich der Lagerbolzen 56 eine Bewegung entlang der Längsachse der Steckerstifte 6 aus, so dass das Steckergehäuse 5 die Steckdosenvertiefung 31 bereichsweise verlässt (Fig. 5). Diese Bewegung kann solange ausgeführt werden, bis das Steckerteil 4 die Steckdosenvertiefung 31 vollständig verlassen hat. Durch die Hebelwirkung im Falle eines Ziehens an dem Steckergehäuse 5 im Bereich des Kabelanschlussraums 7 und dem davon recht weit entfernten Abstützpunkt des Gehäuses 5 auf den Rahmen 32 ist die erforderliche Kraft, um den Netzstecker 1 aus der Steckdose 3 herauszuziehen, wesentlich verringert.Since the pivot axis between plug part 4 and plug housing 5 is arranged on the extension of the longitudinal axis of the plug pins 6 and the boom 58 is provided on the side facing away from the user of the bearing axis, the pivoting about the bearing axis leads to a support effect of the boom 58 outside of Socket recess 31, in the embodiment of the frame 32. Since the boom 58 represents the outermost point of the connector housing 5, the connector housing 5 performs in the region of the bearing pin 56 a movement along the longitudinal axis of the connector pins 6, so that the connector housing 5, the socket recess 31st partially leaves ( Fig. 5 ). This movement can be carried out until the plug part 4 has completely left the socket recess 31. Due to the leverage in the event of pulling on the connector housing 5 in the region of the cable connection space 7 and the far away from the support point of the housing 5 on the frame 32, the force required to pull the power plug 1 from the socket 3, significantly reduced.

Für den Fall, dass in nichtbestimmungsgemäßem Gebrauch an dem Netzkabel 2 zum Herausziehen des Netzsteckers 1 aus der Steckdose 3 gezogen wird, tritt die gleiche Wirkung auf. Auch hier bewirkt der durch den Ausleger 58 geschaffene Hebel eine Verringerung der Auszugskraft des Steckers. Auf Grund der lediglich geringeren aufzubringenden Kraft ist somit die Beschädigung des Steckers durch unsachgemäßes Ziehen am Netzkabel wesentlich verringert.In the event that is pulled in improper use of the power cord 2 to pull out the power plug 1 from the socket 3, the same effect occurs. Again, created by the boom 58 lever causes a reduction in the pull-out force of the plug. Due to the only lower applied force thus damage to the connector is significantly reduced by improper pulling on the power cord.

Claims (4)

  1. Mains plug (1) for connecting a mains cable (2) to a safety wall socket (3), having a plug housing (5) and a connector device (4) in which connecting pins (6) are arranged which are connected with the mains cable (2), where the connector device (4) is arranged around a pivoting axis to pivot on the plug housing (5), and where the plug housing (5) has an extension (58) which is supported outside the socket recess (31) of the safety socket (3), characterised in that the mains cable (2) can be connected to the plug housing (5) and that the extension (58) creates a levering effect which reduces the amount of force required to extract the mains plug (1).
  2. Mains plug (1) according to claim 1, characterised in that the pivoting axis is arranged at right angles to the lengthwise axis of the connecting pins (6).
  3. Mains plug (1) according to claim 1 or claim 2, characterised in that a cable-connecting compartment (7) for connecting the mains cable (2) is provided at one end of the plug housing (5).
  4. Mains plug (1) according to claim 3, characterised in that the extension (58) is arranged at the end of the plug housing (5) facing away from the cable-connecting compartment (7).
