Description
Elektrische Sicherheits-Steckdose Die vorliegende Erfindung bezieht sich auf eine elektrische Sicherheitssteckdose mit Stromabnehmer- hülsen zur Aufnahme der Steckerbolzen eines an eine Speiseleitung anzuschliessenden Steckers.
Bei den bekannten Steckdosen dieser Art können sich Unfälle, insbesondere von Kindern, dadurch er geben, dass die Steckerbolzen nur unvollständig in die Steckdose eingesteckt und dabei berührt werden, oder dass in eine Stromabnehmerhülse der Steckdose ein Metallstift eingeführt wird.
Unfälle dieser Art sind durch die Erfindung ausgeschlossen, indem diese vorsieht, dass an den inneren Stimenden der genann ten Stromabnehmerhülsen <B>je</B> ein Isolierkörper unter Federkraft anliegt, welche Isolierkörper auf ihren inneren Seiten<B>je</B> einen elektrischen Kontakt tragen, der mit einer anderen Stromabnehmerhülse elektrisch verbunden ist zum Zwecke,
beim Einführen eines Metallstiftes in eine Stromabnehmerhülse den ihr zugeordneten Isolierkörper mit seinem Kontakt ge gen die rückstellende Federkraft erst nach einem bestimmten Weg zur Anlage an einen an die Speise leitung angeschlossenen Gegenkontakt zu bringen und dadurch die andere Stromabnehmerhülse mit der Speiseleitung elektrisch zu verbinden.
Ein Ausführungsbeispiel einer derartigen Sicher heitssteckdose ist in der Zeichnung dargestellt. Es handelt sich dabei um eine zweipolige Steckdose.
Im Isolierkröper <B>1</B> der Steckdose, der aus ver schraubten Teilen bestehen kann, sind zwei Strom- abnehmerhülsen 21 und 22, z. B. Messinghülsen, montiert. Die Anschlussleitungen sind mit<B>31</B> und<B>32</B> bezeichnet. Sie sind mittels Schraubklemmen <B>310</B> und<B>320</B> an feststehende Kontakte<B>311</B> bzw. <B>322</B> an geschlossen.
An den inneren Stirnenden der Hülsen 21 und 22 sind Isolierkörper 41 bzw. 42 in Axial- richtung der Hülsen verschiebbar angeordnet, welche auf der inneren Seite, das heisst den Hülsen abgewen det,<B>je</B> einen Kontakt 410 bzw. 420 tragen. Diese Kontakte sind über Leiter 421 bzw. 422<B>je</B> mit einer anderen Steckerhülse elektrisch verbunden. Es ist hier angenommen, dass diese Leiter 421, 422 zugleich Blattfedem bilden, welche die Isolierkörper 41, 42 unter Federkraft an die inneren Stirnenden der ihnen zugeordneten Stromabnehmerhülsen andrücken.
Es könnten zu diesem Zweck aber auch besondere Federorgane vorgesehen werden.
Wenn nun beispielsweise in die Hülse 21 ein Metallstift eingeführt wird, so wird er nicht an einen Spannungspol angeschlossen, auch nicht, wenn gegen die Kraft der Rückstellfeder der Isolierteil 41 so weit hineingedrückt wird, bis sein Kontakt 410 am Gegen kontakt<B>311</B> anliegt, weil dadurch nicht die Hülse 21, sondern die andere Hülse 22 an den Polleiter<B>31</B> angeschlossen wird.
Wenn ein normaler Stecker<B>S</B> (strichpunktiert ge zeichnet) in die Steckdose eingeführt wird, so werden dessen Steckbolzen erst nach fast vollständiger Ein führung an die Polleiter angeschlossen, das heisst wenn sie nicht mehr berührt werden können.
Electrical safety socket The present invention relates to an electrical safety socket with current collector sleeves for receiving the plug pins of a plug to be connected to a feed line.
In the known sockets of this type, accidents, especially of children, can be that the plug pins are only incompletely inserted into the socket and touched, or that a metal pin is inserted into a current collector sleeve of the socket.
Accidents of this type are ruled out by the invention in that it provides that an insulating body rests under spring force on the inner ends of the pantograph sleeves mentioned, which insulating bodies are on their inner sides carry an electrical contact that is electrically connected to another current collector sleeve for the purpose,
when inserting a metal pin into a current collector sleeve, the associated insulating body with its contact ge conditions to bring the restoring spring force only after a certain path to abut on a mating contact connected to the feed line and thereby electrically connect the other current collector sleeve to the feed line.
An embodiment of such a safety socket is shown in the drawing. It is a two-pole socket.
In the insulating body <B> 1 </B> of the socket, which can consist of screwed parts, two current collector sleeves 21 and 22, z. B. brass sleeves mounted. The connection lines are labeled <B> 31 </B> and <B> 32 </B>. They are connected to fixed contacts <B> 311 </B> and <B> 322 </B> by means of screw terminals <B> 310 </B> and <B> 320 </B>.
On the inner front ends of the sleeves 21 and 22, insulating bodies 41 and 42 are arranged displaceably in the axial direction of the sleeves, which on the inner side, i.e. facing away from the sleeves, each have a contact 410 or 420 wear. These contacts are electrically connected to another connector sleeve via conductors 421 or 422 each. It is assumed here that these conductors 421, 422 also form leaf springs which press the insulating bodies 41, 42 under spring force against the inner end faces of the current collector sleeves assigned to them.
However, special spring elements could also be provided for this purpose.
If, for example, a metal pin is inserted into the sleeve 21, it is not connected to a voltage pole, not even if the insulating part 41 is pushed in against the force of the return spring until its contact 410 is at the counter contact <B> 311 < / B>, because this means that it is not the sleeve 21 but the other sleeve 22 that is connected to the pole conductor <B> 31 </B>.
If a normal plug <B> S </B> (shown in dash-dotted lines) is inserted into the socket, its socket pins are only connected to the pole conductor after they have been almost completely inserted, i.e. when they can no longer be touched.
