Description

Die vorliegende Erfindung betrifft eine Kabelverbindungsvorrichtung zur Fixierung von Energiekabeln und zum Herstellen einer elektrischen Verbindung zwischen Energiekabeln nach dem Oberbegriff des Anspruchs 1.The present invention relates to a cable connection device for fixing of power cables and for establishing an electrical connection between Power cables according to the preamble of claim 1.

Derartige Kabelverbindungsvorrichtungen müssen aufgrund der enormen Dicke der zu verbindenden Energiekabel extreme Zugkräfte aushalten, ohne in ihrer Funktion beeinträchtigt zu werden.Such cable connection devices must because of the enormous thickness of the endure extreme tensile forces to be connected without their function to be affected.

In Figur 1 ist eine übliche Kabelverbindungsvorrichtung für Energiekabel gemäß dem bisher bekannten Stand der Technik im Querschnitt dargestellt. Die Kabelverbindungsvorrichtung 51 weist eine Buchse 52 auf, in die zwei auf einer Achse ausgerichtete Hohlräume 53 eingeformt sind, die lediglich durch eine in der Buchse vorhandene Zwischenwand 63 getrennt sind. Die Hohlräume 53 sind zylinderförmig ausgebildet und dienen zur Aufnahme jeweils eines mehrteiligen Kontaktierelements 54, das aus einer Kontakthülse 55 und einer Arretiereinrichtung 57 zusammengesetzt ist. Die Kontakthülse 55 besteht aus einem zum Inneren der Buchse 52 hin zulaufenden Konus 62, der mit Schlitzen versehen ist, und einem äußeren Ring 61, in dessen Außenseite 60 Kontaktierbänder 56 zur Herstellung der leitenden Verbindung mit den Wänden der Buchse 52 eingebracht sind. Ring 61 und Konus 62 sind als getrennte Teile ausgebildet, wobei der Ring 61 an seiner Innenfläche ebenfalls nach innen hin abgeschrägt ist, um die Einführung des Konus 62 zu vereinfachen und dessen Fixierung zu gewährleisten. Bei der Montage wird zunächst das Energiekabel (nicht gezeigt) in den Konus 62 eingeführt, wo es an seinem vorderen Ende aufgrund der Verengung leicht festgehalten wird. Daraufhin wird der Ring 61 über den Konus 62 geschoben und gemeinsam mit diesem in den Hohlraum 53 eingeführt. Um das Energiekabel fest zu verankern und eine elektrische Verbindung mit der Buchse herzustellen, wird nun über die Arretiervorrichtung 57 die erforderliche Kontaktkraft mittels eines hydraulischen Werkzeugs auf den Konus 62 übertragen. Dadurch wird der Konus 62 derart in Richtung des Inneren der Buchse verschoben, daß er im Inneren des Rings 61 zusammengepreßt wird. Damit ist eine sichere Verbindung geschaffen, die praktisch nicht mehr gelöst werden kann. Über die Kontakthülse 55 und die daran angeordneten Kontaktierbänder 56 wird eine elektrische Verbindung zur elektrisch leitenden Buchse 52 und gleichzeitig zum im anderen Hohlraum angeordneten Energiekabel hergestellt. Allerdings ist die Montage der Energiekabel in die Kabelverbindungsvorrichtung relativ kompliziert und erfordert gleichzeitig weitere Zusatzwerkzeuge bzw. Einsätze. Nachteile weist die Vorrichtung des Standes der Technik auch dadurch auf, daß sie nur sehr eingeschränkt für Kabel unterschiedlicher Querschnitte verwendbar ist.In Figure 1 is a common cable connection device for power cables according to the previously known prior art shown in cross section. The cable connection device 51 has a socket 52 into which two are aligned on one axis Cavities 53 are formed by only one in the socket existing partition 63 are separated. The cavities 53 are cylindrical trained and each serve to accommodate a multi-part contacting element 54, which is composed of a contact sleeve 55 and a locking device 57 is. The contact sleeve 55 consists of an inside of the socket 52 tapered cone 62, which is provided with slots, and an outer ring 61, on the outside 60 contact strips 56 for producing the conductive Connection with the walls of the socket 52 are introduced. Ring 61 and cone 62 are formed as separate parts, with the ring 61 on its inner surface is also beveled inwards to simplify the insertion of the cone 62 and to ensure its fixation. When assembling it first the power cable (not shown) is inserted into the cone 62 where it is at its front End is easily held due to the narrowing. Then the Ring 61 pushed over the cone 62 and together with this into the cavity 53 introduced. To firmly anchor the power cable and an electrical one Establishing connection with the socket is now via the locking device 57 the required contact force on the cone using a hydraulic tool 62 transmitted. As a result, the cone 62 is thus in the direction of the interior of the Bush moved that it is compressed inside the ring 61. In order to a secure connection is created that can no longer be solved practically can. Via the contact sleeve 55 and the contact strips 56 arranged thereon becomes an electrical connection to the electrically conductive socket 52 and at the same time to the power cable arranged in the other cavity. However the assembly of the power cables in the cable connection device is relatively complicated and at the same time requires additional tools or inserts. disadvantage has the device of the prior art in that it only very limited use for cables of different cross-sections.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Kabelverbindungsvorrichtung zur Fixierung von Energiekabeln und zum Herstellen einer elektrischen Verbindung zwischen Energiekabeln zu schaffen, bei der die Montage der Energiekabel besonders einfach vonstatten geht, die gleichzeitig für Kabel unterschiedlicher Querschnitte geeignet ist und eine Senkung der Materialkosten gewährleistet.The present invention is therefore based on the object of a cable connecting device for fixing energy cables and for producing an electrical one To create connection between power cables, in which the assembly of the Energy cables are particularly easy to use, but they can also be used for different cables Cross-sections are suitable and a reduction in material costs is guaranteed.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Dadurch, daß das Energiekabel mittels mindestens einer an der Außenseite in die Umfangswand der Kontakthülse einschraubbaren Schraube elektrisch leitend mit der Kontakthülse verbindbar und in dieser klemmbar ist, wird eine sichere Verankerung und elektrische Verbindung des Energiekabels in der Kabelverbindungsvorrichtung geschaffen, die ohne zusätzliche Werkzeuge hergestellt werden kann.The fact that the power cable by means of at least one on the outside in the Circumferential wall of the screw-in screw with an electrically conductive screw the contact sleeve is connectable and can be clamped in it, a secure anchoring and electrical connection of the power cable in the cable connection device created that can be manufactured without additional tools.

Vorteilhafterweise weist die Kontakthülse zwei oder mehr Schrauben auf, wodurch die Fixierung auf mehrere Bereiche des Leiters gestützt werden kann.The contact sleeve advantageously has two or more screws, as a result of which the fixation can be supported on several areas of the conductor.

Zur Festlegung insbesondere von Leitern mit geringerem Querschnitt bzw. unrundem Querschnitt ist es von besonderem Vorteil, daß die Schrauben derart über den Außenumfang der Kontakthülse verteilt sind, daß sie unter verschiedenen Winkeln auf das Energiekabel schraubbar sind.For the determination of conductors with a smaller cross-section or out of round Cross-section, it is particularly advantageous that the screws over the The outer circumference of the contact sleeve is distributed so that it is at different angles can be screwed onto the power cable.

Von besonderem Vorteil ist es, daß die Schraube als Abreißkopfschraube ausgebildet ist, so daß unabhängig von der Dicke des Querschnitts des Energiekabels ein Überstehen der Schraube über den Außenumfang der Kontakthülse hinaus vermieden wird. Dabei ist die Abreißkopfschraube so dimensioniert, daß der Abreißkopf bei einem vorbestimmten Drehmoment abschert und die Schraube die geforderte Klemmkraft bereitstellt.It is particularly advantageous that the screw is designed as a tear-off head screw is so that regardless of the thickness of the cross section of the power cable the screw protrudes beyond the outer circumference of the contact sleeve is avoided. The tear-off head screw is dimensioned so that the tear-off head shears at a predetermined torque and the screw provides the required clamping force.

Zur Vereinfachung des Einführens des Kabelleiters in die Kontakthülse ist vorteilhafterweise vorgesehen, daß jede Kontakthülse einen zylinderförmigen Innenraum aufweist.To simplify the insertion of the cable conductor into the contact sleeve is advantageous provided that each contact sleeve has a cylindrical interior having.

Eine besonders einfache und sichere Arretierung der Kontakthülse wird dadurch erreicht, daß die Arretiereinrichtung als ein in einer Nut auf der Außenseite der Kontakthülse angeordneter Federring ausgebildet ist, der sich in eine in der Innenwand des Hohlraums der Buchse geformte Kerbe ausdehnt, wenn das Kontaktierelement in den Hohlraum eingeführt ist.A particularly simple and secure locking of the contact sleeve is thereby achieved that the locking device as a in a groove on the outside of the Contact sleeve arranged spring ring is formed, which in a in the inner wall of the cavity of the socket extends notch when the contacting element is inserted into the cavity.

Die Fixierung des Kabelleiters in der Kontakthülse wird dadurch verstärkt, daß die Innenseite der Kontakthülse mit einer Innenrillung versehen ist.The fixation of the cable conductor in the contact sleeve is reinforced by the fact that Inside of the contact sleeve is provided with an internal groove.

Bezugnehmend auf Figur 2 wird der prinzipielle Aufbau der erfindungsgemäßen Kabelverbindungsvorrichtung 1 erläutert. Die Kabelverbindungsvorrichtung 1 weist in einer bevorzugten Ausführungsform eine Buchse 2 auf, in der zwei in einer Linie liegende Hohlräume 3 hintereinander angeordnet sind. Die beiden Hohlräume 3 sind zylinderförmig ausgebildet und lediglich durch eine Zwischenwand 13 der Buchse 2 voneinander getrennt. In die Hohlräume 3 sind zwei Kontaktierelemente 4 einführbar, die als Kontakthülsen 5 ausgebildet sind. Der Außendurchmesser der Kontaktierelemente 4 ist nur geringfügig geringer als der Innendurchmesser der zylinderförmigen Hohlräume 3. Die Kontakthülsen 5 weisen einen zylinderförmigen Innenraum 14 auf, in den das Energiekabel (nicht gezeigt) eingeführt und dort gesichert werden kann, was weiter unten noch genauer beschrieben wird.Referring to Figure 2, the basic structure of the invention Cable connection device 1 explained. The cable connection device 1 has in a preferred embodiment, a socket 2, in the two in a line lying cavities 3 are arranged one behind the other. The two cavities 3 are cylindrical and only by an intermediate wall 13 of the Socket 2 separated. In the cavities 3 are two contacting elements 4 insertable, which are designed as contact sleeves 5. The outside diameter of the Contacting elements 4 is only slightly smaller than the inside diameter of the cylindrical cavities 3. The contact sleeves 5 have a cylindrical Interior 14 in which the power cable (not shown) is inserted and secured there what can be described in more detail below.

Die Kontakthülsen 5 weisen jeweils ein, im dargestellten Beispielsfalle zwei Kontaktierbänder 6 an ihrer Außenseite 10 auf, die Toleranzen ausgleichen und eine sichere elektrische Verbindung zwischen Kontakthülse 5 und elektrisch leitender Buchse 2 herstellen, wenn die Kontakthülse 5 in den Hohlraum 3 eingeführt ist. Je nach zu übertragender Stromstärke können auch noch mehr Kontaktierbänder 6 vorgesehen werden. Eine Arretiervorrichtung 7 dient zur Verankerung der Kontakthülse 5 in der Buchse 2. Hierzu ist an der Außenseite 10 der Kontakthülse 5, bevorzugt an ihrem nach außen hin orientierten Ende, eine Nut 11 vorgesehen, in der sich ein Federring 9 befindet. In montiertem Zustand dehnt sich dieser in eine an der Innenwand des Hohlraumes 3 eingeformte Kerbe 12 aus, wobei zumindest ein Teil des Federrings noch in der Nut 11 verbleibt, so daß eine einfache und sichere Fixierung der Kontakthülse 5 in der Buchse 2 erreicht wird.The contact sleeves 5 each have two contact strips in the example shown 6 on its outside 10, compensate for the tolerances and one secure electrical connection between contact sleeve 5 and electrically conductive Make socket 2 when the contact sleeve 5 is inserted into the cavity 3. ever depending on the current to be transmitted, even more contact strips 6 be provided. A locking device 7 serves to anchor the contact sleeve 5 in the socket 2. For this purpose, the contact sleeve 5 on the outside 10 is preferred at its outwardly oriented end, a groove 11 is provided in the there is a spring ring 9. When assembled, it expands into one of the inner wall of the cavity 3 formed notch 12, at least one Part of the spring ring still remains in the groove 11, so that a simple and safe Fixation of the contact sleeve 5 in the socket 2 is reached.

In Figur 3 ist eine erfindungsgemäße Ausführungsform einer Kontakthülse 5 perspektivisch dargestellt. Deutlich sind auch hier die Kontaktierbänder 6 an der Außenseite der Kontakthülse zu erkennen, sowie eine bevorzugt als Abreißkopfschraube ausgebildete Schraube 8, die in die Umfangswand der Kontakthülse 5 einschraubbar ist, wodurch das Energiekabel sicher in der Kontakthülse fixiert wird. Bei Verwendung normaler Schrauben ist es wichtig, daß der Schraubenkopf vollständig in die Umfangswand der Kontakthülse 5 hinein versenkt wird, da sonst ein Einführen der Kontakthülse 5 in einen Hohlraum 3 der Buchse 2 nicht möglich ist.In Figure 3, an embodiment of a contact sleeve 5 according to the invention is in perspective shown. The contact strips 6 on the outside are also clear here to recognize the contact sleeve, and a preferably as a tear-off screw trained screw 8, which in the peripheral wall of the contact sleeve 5th can be screwed in, as a result of which the energy cable is securely fixed in the contact sleeve. When using normal screws, it is important that the screw head is complete is sunk into the peripheral wall of the contact sleeve 5, otherwise a Inserting the contact sleeve 5 into a cavity 3 of the socket 2 is not possible.

Um auch Leiter mit geringerem Leiterquerschnitt und beliebiger geometrischer Querschnittsform sicher in der Kontakthülse 5 fixieren zu können, ist es auch möglich, wie durch die Schraubenlöcher in Figur 3 angedeutet, mehrere Schrauben an verschiedenen Stellen des Umfangs der Kontakthülse anzuordnen. Dabei ist es von Vorteil, wenn die Schrauben zwar unter verschiedenen Winkeln, aber doch aus einer Hauptrichtung auf das Energiekabel gepreßt werden.To also conductors with a smaller conductor cross-section and any geometrical To be able to securely fix the cross-sectional shape in the contact sleeve 5, it is also possible as indicated by the screw holes in Figure 3, several screws to arrange different places on the circumference of the contact sleeve. It is an advantage if the screws are from different angles, but still a main direction to be pressed on the power cable.

In Figur 4 ist ein Querschnitt der Kontakthülse 5 aus Figur 3 bei Verwendung einer Abreißkopfschraube 8 dargestellt. Die Begrenzungswände des Innenraums 14 der Kontakthülse 5 können zur besseren Fixierung des eingeführten Energiekabels mit einer Innenrillung versehen sein.In Figure 4 is a cross section of the contact sleeve 5 of Figure 3 when using a Tear-off screw 8 shown. The boundary walls of the interior 14 of the Contact sleeve 5 can with better fixation of the inserted power cable be provided with an internal groove.

Ist das Energiekabel in den Innenraum 14 eingeführt, so wird die Abreißkopfschraube so lange gedreht, bis ein vorbestimmtes Drehmoment überschritten wird, und der Kopf der Schraube an einer Sollbruchstelle 15 abgetrennt wird. Im Anschluß daran wird die Kontakthülse 5 in den Hohlraum 3 der Buchse 2 eingeführt, bis sie mit ihrem vorderen Ende am Mittelsteg 13 der Buchse 2 anstößt. In dieser Position dehnt sich der Federring 9 in die Kerbe 12 aus und fixiert die Kontakthülse 5 in der Buchse 2. Somit wird über die Abreißkopfschraube 8, Kontakthülse 5, die Kontaktierbänder 6 und die elektrisch leitende Buchse 2 eine sichere leitende Verbindung zwischen zwei Energiekabeln hergestellt, ohne zusätzliche Werkzeuge einsetzen zu müssen.If the power cable is inserted into the interior 14, the tear-off head screw turned until a predetermined torque is exceeded, and the head of the screw is severed at a predetermined breaking point 15. In connection then the contact sleeve 5 is inserted into the cavity 3 of the socket 2, until its front end abuts the central web 13 of the socket 2. In this Position, the spring ring 9 expands into the notch 12 and fixes the contact sleeve 5 in the socket 2. Thus, the tear-off screw 8, contact sleeve 5, the Contact strips 6 and the electrically conductive socket 2 a secure conductive connection made between two power cables, without additional tools to have to use.

Die exakte Lage der Kontaktierbänder, der Arretiervorrichtung und die Art der verwendeten Abreißkopfschraube können hierbei je nach Verwendungszweck unterschiedlich gewählt werden.The exact location of the contact strips, the locking device and the type of used Tear-off screw can vary depending on the intended use to get voted.
