Abstract
Description
Die Erfindung betrifft einen Netzstecker mit einem Steckergehäuse, aus dem Boden des Steckergehäuses herausragende Kontaktstifte und einer in dem Steckergehäuse gelagerten Zugentlastung, an der das Anschlusskabel befestigt ist, sowie eine mit einem solchen Netzstecker versehene Netzsteckeranordnung.The The invention relates to a power plug with a plug housing the bottom of the connector housing outstanding contact pins and one in the connector housing Strain relief to which the connection cable is attached, as well as with such a power plug provided power plug assembly.
Netzstecker elektrischer Geräte können bei dem Auftreten einer Zug- oder Querkraft auf das an sie angeschlossene Kabel mechanisch derart belastet werden, das sie oder die Steckdose, in die sie eingeführt sind, beschädigt werden. Weiter kann es sein, dass eine unbeabsichtigte und unbemerkte Trennung vom Netz eintritt, was bei manchen Anwendungsfällen – etwa im Krankenhaus – fatale Folgen haben kann.power plug electrical devices can when a tensile or transverse force occurs on the connected one Cables are mechanically loaded in such a way that they or the socket, into which they are introduced are damaged become. Furthermore, there may be an unintentional and unnoticed separation enters the network, which is fatal in some applications - for example in hospitals Can have consequences.
Aus
der
Der Nachteil dieser Art Netzstecker besteht darin, dass der Netzstecker für in zur Richtung des Netzsteckers axial wirkende Zugkräfte nur unzureichend gesichert ist und eine unbeabsichtigte Trennung vom Netz weiterhin unbemerkt bleibt.The The disadvantage of this type of power plug is that the power plug for in pulling forces acting axially to the direction of the power plug only is insufficiently secured and an unintentional separation from the Network remains unnoticed.
Der Erfindung liegt die Aufgabe zugrunde, einen Netzstecker bzw. eine Netzsteckeranordnung zu schaffen, bei der die Gefahr einer Beschädigung von Stecker oder Steckdose bei Auftreten einer Zug- oder Querkraft auf das Kabel verringert ist.The The invention has for its object a power plug or To create a power plug assembly at the risk of damage to the plug or socket if a tensile or transverse force occurs on the cable is reduced.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass bei dem eingangs genannten Netzstecker die Zugentlastung gegen ein auf Belastung ansprechendes Element beweglich gelagert ist, die Zugentlastung mit einem sich mit diesem bewegenden ersten Kontaktstück versehen ist, das Steckergehäuse mit einem zweiten Kontaktstück versehen ist, das Steckergehäuse mit einem in einem die Kontaktstücke einschließenden Stromkreis liegenden Melder versehen ist, wobei der Melder aktiviert wird, wenn auf die Zugentlastung ein Zug ausgeübt wird, der die Kontaktstücke in Berührung bringt und damit den Stromkreis schließt.According to the invention Task solved by that the strain relief against the above-mentioned power plug a load-responsive element is movably mounted, the Strain relief with a moving with this first contact piece is the connector housing with a second contact piece is provided, the connector housing with one in one the contact pieces inclusive Circuit detector is provided, the detector being activated, if a pull is exerted on the strain relief that brings the contact pieces into contact and thus closes the circuit.
Die Netzsteckeranordnung ist erfindungsgemäß mit einem eingangs genannten Netzstecker und einem Zwischensteckerteil versehen, wobei bei dem Netzstecker, die Zugentlastung gegen ein auf Belastung ansprechendes Element beweglich gelagert ist, die Zugentlastung mit einem sich mit diesem bewegenden ersten Kontaktstück versehen ist, der Netzstecker mit einem zweiten Kontaktstück versehen ist, am Boden des Netzsteckers erste Kontaktpunkte, die mit den ersten Kontaktstücken elektrisch verbunden sind, angeordnet sind, und bei dem Zwischensteckerteil zwei an dessen Boden angeordneten, mit den ersten Kontaktpunkten des Netzsteckers zusammenwirkenden zweiten Kontaktpunkten vorgesehen sind, zwei Kontaktlamellen zum Aufnehmen der Kontaktstifte des Netzsteckers vorgesehen sind, ein elektrisch auslösbarer Linearantrieb vorgesehen ist, ein von dem Linearantrieb betätigter Auslösemechanismus vorgesehen ist und eine auf dem Zwischensteckerteil axial gegen ein eine Kraft ausübenden Mittel verschieblich gelagerte, das Steckerteil aufnehmende, von dem Auslösemechanismus bei dessen Aktivierung betätigte und dabei den Netzstecker auswerfende Auswurfhülsehülse vorgesehen ist.The According to the invention, the power plug arrangement is equipped with a plug Power plug and an adapter plug part, with the power plug, the strain relief against an element responsive to load Is movably mounted, the strain relief with one with this moving first contact piece is provided, the power plug with a second contact piece is at the bottom of the power plug, the first contact points with the first contact pieces are electrically connected, arranged, and in the intermediate connector part two arranged at the bottom, with the first contact points of the power plug interacting second contact points are provided, two contact lamellas for receiving the contact pins of the mains plug are provided, an electrically triggerable linear drive is provided is, a trigger mechanism actuated by the linear drive is provided and one on the adapter part axially against a force performing Medium displaceably mounted, receiving the plug part, from the trigger mechanism actuated when it was activated and eject sleeve sleeve ejecting the power plug is provided.
Der Zwischensteckerteil ist vorzugsweise mit einem Melder versehen.The The adapter part is preferably provided with a detector.
Das eine Kraft ausübende Element kann ein federelastisches Element sein, es kann sich dabei aber auch um einen elektromotorischen oder pneumatischen Antrieb handeln.The a force exercising Element can be a resilient element, but it can also act as an electric motor or pneumatic drive.
Als elektromagnetischer Entriegelungsmechanismus kann ein elektrothermisches Element (Bimetall) eingesetzt werden.As electromagnetic unlocking mechanism can be an electrothermal Element (bimetal) can be used.
Die Auslösung kann bei einer bevorzugten Ausführungsform auch durch Fernauslösung (etwa im Brandfall) erfolgen, die Auslösung kann auch bei einem Auftreten eines Fehlerstroms oder einer Übertemperatur erfolgen.The release can in a preferred embodiment also by remote triggering (e.g. in the event of a fire), the trigger can also occur fault current or overtemperature respectively.
