Abstract
Description
Die vorliegende Erfindung betrifft eine Trennvorrichtung nach dem Oberbegriff des Anspruchs 1 (vgl.
Es ist die Aufgabe der vorliegenden Erfindung, eine Vorrichtung der eingangs genannten Art zu schaffen, die bei schneller Auslösung kompakt baut.It is the object of the present invention to provide a device of the type mentioned, which builds compact at fast triggering.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1.The solution of this object is achieved by the features of claim 1.
Erfindungsgemäß ist der zu trennende Leiter zumindest teilweise als Hohlleiter ausgebildet, so dass es möglich ist, die Trenneinrichtung in das Innere des Hohlleiters einzubringen. Hierdurch wird nicht nur eine sehr kompakte Bauweise erreicht sondern es ist auch möglich, durch die Trenneinrichtung den Hohlleiter von innen nach außen zu durchtrennen, was mit wesentlich geringeren Kräften möglich ist, als wenn der Hohlleiter von außen nach innen durchtrennt würde.According to the invention the conductor to be separated is at least partially formed as a waveguide, so that it is possible to introduce the separator into the interior of the waveguide. As a result, not only a very compact design is achieved but it is also possible to cut through the separator the waveguide from the inside out, which is possible with much lower forces, as if the waveguide would be cut from outside to inside.
Vorteilhafte Ausführungsformen der Erfindung sind in der Beschreibung, der Zeichnung sowie den Unteransprüchen beschrieben.Advantageous embodiments of the invention are described in the description, the drawings and the subclaims.
Nach einer ersten vorteilhaften Ausführungsform ist der Hohlleiter in dem Abschnitt hülsenförmig und insbesondere nach Art einer geschlossenen Hülse ausgebildet und die Trenneinrichtung tritt nach Auslösen des Antriebs im Wesentlichen entlang des gesamten Innenumfangs mit der Hülse in Eingriff. Die Hülse muss jedoch nicht notwendigerweise vollständig geschlossen oder kreisrund ausgebildet sein. Bei dieser Ausführungsform wird ein besonders rasches und sicheres Trennen des Leiters sichergestellt, da einerseits entlang des gesamten Innenumfangs des Leiters ein Abtrennen erfolgt und da andererseits der Leiter aufgrund seiner hülsenförmigen Ausbildung vergleichsweise dünnwandig hergestellt werden kann.According to a first advantageous embodiment, the waveguide is formed sleeve-shaped in the section and in particular in the manner of a closed sleeve and the separator occurs after triggering of the drive substantially along the entire inner circumference with the sleeve into engagement. However, the sleeve need not necessarily be completely closed or circular. In this embodiment, a particularly rapid and safe separation of the conductor is ensured, since on the one hand along the entire inner circumference of the conductor separation takes place and on the other hand, the conductor can be made relatively thin-walled due to its sleeve-shaped configuration.
Nach einer weiteren vorteilhaften Ausführungsform weist die Trenneinrichtung einen sich konisch erweiternden Kolben auf. Hierdurch kann mit Hilfe des Antriebs der Kolben in das Innere der Spreizhülse bewegt werden, wobei sich die Spreizhülse durch die konisch erweiternde Form des Kolbens nach außen aufspreizt und dadurch den Hohlleiter trennt. Um das Aufspreizen der Spreizhülse zu erleichtern, kann diese bereichsweise geschlitzt ausgebildet sein. Darüber hinaus kann es vorteilhaft sein, auch den Hohlleiter mit Öffnungen, insbesondere Schlitzen zu versehen, da hierdurch das Abtrennen bzw. das Aufspreizen des Hohlleiters erleichtert wird.According to a further advantageous embodiment, the separating device has a conically widening piston. As a result, with the aid of the drive, the piston can be moved into the interior of the expansion sleeve, wherein the expansion sleeve spreads outwardly by the conically widening shape of the piston and thereby separates the waveguide. In order to facilitate the spreading of the expansion sleeve, this can be formed partially slotted. In addition, it may be advantageous to provide the waveguide with openings, in particular slots, as this the separation or spreading of the waveguide is facilitated.
Sofern der Hohlleiter und die Spreizhülse miteinander fluchtende Öffnungen, insbesondere Schlitze, aufweisen, wird der Trennvorgang erleichtert.If the waveguide and the expansion sleeve having mutually aligned openings, in particular slots, the separation process is facilitated.
Nach einer weiteren vorteilhaften Ausführungsform weist die Trenneinrichtung einen von dem Antrieb abtrennbaren Kolben auf. Auf diese Weise ist eine kompakte Baueinheit geschaffen, bei der der Kolben nicht separat montiert werden muss.According to a further advantageous embodiment, the separating device has a piston which can be separated from the drive. In this way, a compact unit is created in which the piston does not have to be mounted separately.
Nach einer weiteren vorteilhaften Ausführungsform ist die Vorrichtung insgesamt rohrförmig ausgebildet und weist an ihren beiden Enden Anschlussmittel für Kabel, insbesondere Ösen oder Crimpelemente auf. Auf diese Weise ist eine äußerst kompakte Trennvorrichtung geschaffen, die sich universell einsetzen lässt, da lediglich die zu unterbrechende Leitung mit den Anschlussmitteln verbunden werden muss.According to a further advantageous embodiment, the device is formed overall tubular and has at its two ends connecting means for cables, in particular eyelets or crimping elements. In this way, an extremely compact separation device is created, which can be used universally, since only the line to be disconnected must be connected to the connection means.
Nach einer weiteren vorteilhaften Ausführungsform weist das Gehäuse einen Aufnahmeraum für von der Trenneinrichtung abgetrennte Segmente des Hohlleiters auf, der nach erfolgter Trennung nahezu vollständig durch Teile des Leiters und der Trenneinrichtung ausgefüllt ist. Bei dieser Ausführungsform ist die Größe des Aufnahmeraumes so gewählt, dass nach erfolgter Auslösung sich nahezu keine Luft im Bereich des getrennten Leiters befindet, wodurch ein Lichtbogen, der bei elektrischer Trennung unter Stromschluss entstehen kann, sich erst gar nicht ausbildet bzw. sich in kürzester Zeit von selbst wieder löscht.According to a further advantageous embodiment, the housing has a receiving space for separated from the separator segments of the waveguide, which is almost completely filled after separation by parts of the conductor and the separator. In this embodiment, the size of the receiving space is chosen so that after triggering almost no air is in the region of the separate conductor, whereby an arc, which can occur under electrical isolation in electrical isolation, not even formed or in the shortest possible time deletes itself again.
Nach einer weiteren vorteilhaften Ausführungsform ist der Leiter ein Stanzteil, das zumindest abschnittsweise zu einer Hülse, insbesondere einer geschlossenen Hülse geformt ist. Ein solches Stanzteil kann kostengünstig aus Blech, z.B. Kupfer- oder Aluminiumblech, gefertigt werden und erlaubt trotz der außerordentlich hohen mechanischen Präzisionsanforderungen eine preisgünstige Herstellung. Das Stanzteil kann aus Bandmaterial gestanzt und über einen Wickeldorn gewalzt werden, um die hülsenförmige Ausbildung zu erreichen. Nach einer weiteren vorteilhaften Ausführungsform kann dabei das Stanzteil an zwei gegenüberliegenden Rändern eine Vielzahl formschlüssig miteinander verbindbarer, komplementär ausgebildeter Abschnitte aufweisen, die beim Wickeln zu einer Hülse ineinander eingefügt werden. Auf diese Weise ergibt sich an der Trennstelle eine äußerst feste Verbindung.According to a further advantageous embodiment of the conductor is a stamped part, which is at least partially formed into a sleeve, in particular a closed sleeve. Such a stamped part can be inexpensively made of sheet metal, such as copper or aluminum sheet, and allows despite the extremely high mechanical precision requirements an inexpensive production. The stamped part can be punched from strip material and rolled over a winding mandrel in order to achieve the sleeve-like design. According to a further advantageous embodiment, the stamped part at two opposite edges a plurality of form-fitting interconnectable, complementary trained sections have, which during winding to a Sleeve are inserted into each other. In this way, results at the separation point an extremely strong connection.
Nach einer weiteren vorteilhaften Ausführungsform weist das Gehäuse eine ringförmige Scherkante auf, wodurch der Hohlleiter entlang seines gesamten Umfangs gleichzeitig abgetrennt werden kann.According to a further advantageous embodiment, the housing has an annular shear edge, whereby the waveguide can be separated simultaneously along its entire circumference.
