Abstract
Description
Die Erfindung betrifft eine Steckvorrichtung für Kabelverbindungen im Hochspannungs-Starkstrombereich nach dem Oberbegriff des Anspruchs 1.The invention relates to a plug-in device for cable connections in the high-voltage high-current range according to the preamble of claim 1.
Es ist bekannt, im Hochspannungs-Starkstrombereich Steckverbindungen z.B. als Innenkonussteckverbindungen auszuführen, bei denen die Kontaktierung zwischen einem Buchsenteil und einem Steckerteil über einen Lamellenfederring erfolgt. Bei diesem handelt es sich jedoch um ein relativ empfindliches und teures Bauelement, das mit seinen Federlamellen nur in recht bescheidenem Umfang Differenzen des zu überbrükkenden Abstandes auffangen kann, so daß man gezwungen ist enge Fertigungstoleranzen beim Außendurchmesser des Steckerteils und beim Innendurchmesser des Buchsenteils einzuhalten.It is known to use plug connections e.g. to be designed as an inner cone plug-in connection in which the contact between a socket part and a plug part takes place via a lamellar spring washer. However, this is a relatively sensitive and expensive component that can only compensate for the differences in the distance to be bridged to a very modest extent with its spring lamellae, so that one is forced to adhere to tight manufacturing tolerances in the outer diameter of the plug part and in the inner diameter of the socket part.
In einem Datenblatt CANTED COIL SPRINGS" der BAL SEAL ENGENEERING EUROPE BV" wird eine neuartige Spiralfeder für verschiedenartigste Anwendungen beschrieben, deren Federwindungen in einer Richtung schräg verlaufen, so daß sie bei radialem Druck eine federnde Kippbewegung ermöglichen. Diese Feder eignet sich auch als Kontaktelement.In a data sheet CANTED COIL SPRINGS "the BAL SEAL ENGENEERING EUROPE BV "describes a new type of spiral spring for a wide variety of applications, the spring windings of which run obliquely in one direction, so that they enable a resilient tilting movement under radial pressure. This spring is also suitable as a contact element.
Aufgabe der Erfindung ist es eine Kontaktierungsvorrichtung nach dem Oberbegriff des Anspruchs 1 zu schaffen, die so aufgebaut ist, daß sie nicht nur eine gute Kontaktgabe ermöglicht, sondern sich bei einfachem Aufbau auch eignet größere Fertigungstoleranzen auszugleichen und die es außerdem ermöglicht die Kontaktelemente so miteinander zu verriegeln, daß ein ungewolltes Öffnen des Kontaktes ausgeschlossen wird.The object of the invention is to provide a contacting device according to the preamble of claim 1, which is constructed in such a way that it not only enables good contact making, but is also suitable to compensate for larger manufacturing tolerances with a simple structure and which also enables the contact elements to be connected to one another lock that an unwanted opening of the contact is excluded.
Diese Aufgabe wird durch die im Anspruch 1 gekennzeichneten Merkmale gelöst. Zweckmäßige Ausgestaltungen und Weiterbildungen des Erfindungsgegenstandes sind in den Unteransprüchen genannt.This object is achieved by the features characterized in claim 1. Appropriate refinements and developments of the subject matter of the invention are mentioned in the subclaims.
Dadurch, daß in Abweichung von der Norm, im koaxialen Bereich zwischen dem Stekkerteil und dem Buchsenteil auf der Innenfläche des Buchsenteils und der Außenfläche des Steckerteils mindestens je eine umlaufende Ringnut ausgebildet ist, und je zwei in der Steckendstellung einander gegenüberliegende Ringnuten gemeinsam einen Federring aufnehmen, gelingt es bei entsprechender Ausbildung des Federrings eine Verrastung zwischen den Kontaktteilen zu erreichen. Hierzu ist vorgesehen mindestens einen Federring als geöffneten oder geschlossenen Spiralfederring auszubilden, der in einer zugehörigen Ringnut liegt und bei dem alle Spiralfederwindungen entlang der Umlaufrichtung seines äußeren, radialen Kreisrings eine vorgegebene einseitige Neigung aufweisen, so daß sie bei radialem Druck auf den Spiralfederring eine diese Neigung verstärkende, definiert federnde Kippbewegung ermöglichen. Der Spiralfederring wird aus einer gestreckten Spiralfeder geformt, deren beide Enden ggf. miteinander verbunden sind. Liegt die zugehörige Ringnut auf einer zylindrischen Innenfläche, so ist ein Verbinden der beiden Spirafederenden überflüssig und die Spiralfeder kann als geöffneter Spiralfederring eingelegt werden.Because, in deviation from the norm, at least one circumferential ring groove is formed in the coaxial area between the plug part and the socket part on the inner surface of the socket part and the outer surface of the plug part, and two ring grooves opposite each other in the plug end position jointly accommodate a spring ring, If the spring washer is designed appropriately, it is possible to achieve a latching between the contact parts. For this purpose, at least one spring ring is provided as an open or closed spiral spring ring, which lies in an associated annular groove and in which all spiral spring windings have a predetermined one-sided inclination along the circumferential direction of its outer, radial circular ring, so that they have this inclination under radial pressure on the spiral spring ring enable reinforcing, defined resilient tilting movement. The spiral spring ring is formed from an elongated spiral spring, the two ends of which may be connected to one another. If the associated ring groove lies on a cylindrical inner surface, connecting the two spiral spring ends is superfluous and the spiral spring can be inserted as an open spiral spring ring.
Ein wesentlicher Vorteil der neuen Steckvorrichtung besteht auch darin, daß der Spiralfederring im Verhältnis zu den Abmessungen der Kontaktelemente so dimensioniert ist, daß er zum Ausgleich von Fertigungstoleranzen größere Differenzen der Ringspaltbreiten überbrücken kann, als das mit einem Lamellenfederring möglich ist.A major advantage of the new plug-in device is also that the spiral spring ring is dimensioned in relation to the dimensions of the contact elements that it can bridge larger differences in the annular gap widths to compensate for manufacturing tolerances than is possible with a lamellar spring washer.
Für das Anbringen des Spiralfederrings im Bereich der Kontaktvorrichtung stehen zwei Möglichkeiten zur Auswahl. So kann der Spiralfederring in eine Ringnut des Buchsenteils eingelegt werden, die ihn gegen axiale Verschiebung sichert. Das Steckerteil muß dann mit einem die korrespondierende Ringnut bildenden Rastnockenring versehen sein, der eine Verriegelungsflanke und eine Entriegelungsflanke besitzt.There are two options for attaching the spiral spring ring in the area of the contact device. So the spiral spring ring can be inserted into an annular groove of the socket part, which secures it against axial displacement. The plug part must then be provided with a locking cam ring forming the corresponding annular groove, which has a locking flank and an unlocking flank.
Alternativ kann der Spiralfederring aber auch in eine Ringnut des Steckerteils eingelegt sein, die ihn gegen axiale Verschiebung sichert. In diesem Fall muß das Steckerteil mit einem Rastnockenring versehen sein, der eine Verriegelungsflanke und eine Entriegelungsflanke besitzt.Alternatively, the spiral spring ring can also be inserted into an annular groove in the plug part, which secures it against axial displacement. In this case, the plug part must be provided with a locking cam ring which has a locking flank and an unlocking flank.
Weiterhin ist vorgesehen, daß die Verriegelungsflanke und die Entriegelungsflanke jeweils als Gleitschrägen ausgebildet sind, die ein erleichtertes Gleiten des Spiralfederrings zum Verrasten beim Einstecken, und Entriegeln beim Herausziehen des Steckerteils ermöglichen. Durch entsprechende. Ausbildung der Schrägen sind bei gegebenen Durchmessern die gewünschten Ver- und Entriegelungskräfte einstellbar.Furthermore, it is provided that the locking flank and the unlocking flank are each designed as sliding bevels, which make it easier to slide the spiral spring ring for locking when plugging in, and unlocking when pulling out the plug part. By appropriate. Formation of the bevels, the desired locking and unlocking forces can be set for given diameters.
Bei den vorbeschriebenen Hochspannungssteckverbindungen ist es erforderlich, daß jeweils Steckerteil und Buchsenteil aufeinander abgestimmt sind. Probleme könnten dort entstehen, wo genormte Hochspannungssteckbuchsen für Innenkonussteckverbindungen bereits in einer Anlage installiert sind und dennoch ohne Neumontage auf die Vorteile einer verrastbaren Steckverbindung nicht verzichtet werden soll. Für diesen Fall ist vorgesehen, daß der Rastnockenring als separates Teil ausgebildet ist und als solches in der genormten Steckbuchse mit zylindrischer Innenfläche an der richtigen Stelle positioniert und durch Haftungsmittel befestigt ist.In the case of the high-voltage plug connections described above, it is necessary that the plug part and socket part are matched to one another. Problems could arise where standardized high-voltage sockets for internal cone connections are already installed in a system and the advantages of a snap-in connection should not be foregone without re-assembly. In this case, it is provided that the locking cam ring is designed as a separate part and as such is positioned in the correct place in the standardized socket with a cylindrical inner surface and is fastened by adhesive.
Einen besonders einfachen Aufbau erhält man, wenn der Spiralfederring so ausgebildet ist und mit dem Steckerteil und dem Buchsenteil so zusammenwirkt, daß er sowohl ein Verrasten als auch ein Kontaktieren zwischen diesen beiden Teilen ermöglicht.A particularly simple construction is obtained if the spiral spring ring is designed and interacts with the plug part and the socket part in such a way that it enables both locking and contacting between these two parts.
Man kann die Steckvorrichtung jedoch auch so aufbauen, daß der Spiralfederring mit dem Steckerteil und dem Buchsenteil so zusammenwirkt, daß er nur oder hauptsächlich ein Verrasten ermöglicht und ein zweiter Federring, der vorzugsweise als Lamellenfederring ausgebildet ist, die Kontaktierung übernimmt. Dies hätte unter anderem den Vorteil, daß ein Federring bezüglich seiner Dimensionierung speziell so ausgelegt werden könnte, daß er sich besonders gut zum Verrasten eignet, während beim anderen Federring ein Material gewählt werden könnte, das eine besonders gute Kontaktierung gewährleistet.However, the plug device can also be constructed in such a way that the spiral spring ring interacts with the plug part and the socket part in such a way that it only or mainly enables locking and a second spring ring, which is preferably designed as a lamellar spring ring, takes over the contacting. This would have the advantage, among other things, that a spring ring could be specially dimensioned in such a way that it is particularly well suited for latching, while a material could be selected for the other spring ring that ensures particularly good contacting.
Alle vorbeschriebenen Vorteile und Verbesserungen lassen sich auch beim Aufbau einer Verbindungsmuffe verwirklichen. Hierbei werden zwei zur Verrastung und Kontaktierung vorgesehene Buchsenteile mit einander entgegengesetzter Einstecköffnung in eine Verbindungsmuffe so integriert, daß sie mit zwei Steckerteilen zusammenwirken können, die über die Verbindungsmuffe zwei Kabelenden miteinander verbindet.All of the advantages and improvements described above can also be realized when building a connecting sleeve. Here, two socket parts intended for latching and contacting are integrated into a connecting sleeve with opposite insertion openings in such a way that they can interact with two plug parts which connect two cable ends to one another via the connecting sleeve.

Wie man in Fig. 1 erkennen kann, besitzt eine Innenkonussteckvorrichtung einen Innenkonusstecker mit einem Steckerteil 1a, einem Gehäuse 23 und einem Feldsteuerkonus 22, der ein Kabelende 20 mit einem Leiterende 19 umschließt und in ein Buchsenteil 2a mit seinem Isolierkörper 21 eingesteckt wird. Zur Kontaktierung zwischen dem Steckerteil 1a und dem Buchsenteil 2a ist ein Spiralfederring 3a vorgesehen, der einen zwischen beiden Teilen liegenden Ringspalt 5 überbrückt.As can be seen in FIG. 1, an inner cone plug device has an inner cone plug with a
Den Fig. 2 und 3 kann man die besondere Ausbildung des Spiralfederrings 3a entnehmen. Der Ring entsteht durch das Verbinden der beiden freien Enden einer langgestreckten Spiralfeder, deren eigentliche Besonderheit jedoch in ihren schräggestellten Spiralfederwindungen 4a besteht. Die in einer Umlaufrichtung 12 gekippten Spiralfederwindungen 4a ermöglichen eine Federwirkung, die durch eine Änderung der jeweiligen Kippstellung der einzelnen Spiralfederwindungen 4a hervorgerufen wird. Bei radialem Druck 13 werden die Spiralfederwindungen 4a mehr oder minder gestaucht. Diesen Vorgang verdeutlicht Fig. 4, in der die Federkraft P in Abhängigkeit vom Federweg dargestellt ist. In ihrer Stellung E hat die Spiralfeder erst einen kurzen Federweg zurückgelegt, was einer geringen Stauchung bzw. Schrägstellung der Federwindungen entspricht. Eine Steigerung der Stauchung zeigt die Stellung F, der die Stauchungsendstellung G folgt. Entgegen dem linearen Kennlinieverlauf A üblicher Spiralfedern weist die hier beschriebene Spiralfeder eine nichtlineare Charakteristik mit steilem Anstieg B im Anfangsbereich, extrem flachem Verlauf im Arbeitsbereich C und wieder steilem Anstieg im Endbereich D auf. Bei einer großen Zahl von Spiralfederwindungen 4a ergibt sich auch eine sehr gute allseits aufliegende Kontaktierung durch die als federnde Segmente 4 wirkenden Spiralfederwindungen 4a.2 and 3 you can see the special design of the
Nach dieser Erläuterung ist leicht zu verstehen, daß ein in eine Ringnut 6 eingelegter Spiralfederring 3a geeignet ist für die notwendige Kontaktierung zu sorgen. Der Spiralfederring 3a taucht in seiner entspannten, also nicht gestauchten Form nur soweit in eine ihn axial fixierende Ringnut 6 ein, daß er aus dieser nicht herausgleiten kann, wenn beim Aufstecken ein axialer Druck auf ihn ausgeübt wird. Andererseits wird man die Tiefe der Ringnut 6 so bemessen, daß der vollständig komprimierte oder gestauchte Spiralfederring 3a in ihr Platz findet. Bei entsprechender Dimensionierung ist mit dem Spiralfederring 3a ein großer Federweg erreichbar, der es ermöglicht große, bzw. sehr unterschiedliche Differenzen zwischen dem äußeren Durchmesser des Steckerteils 1a und dem inneren Durchnesser des Buchsenteils 2a auszugleichen.After this explanation it is easy to understand that a
Die Fig. 5 bis 7 zeigen verschiedene Varianten des Kontaktbereiches eines Innenkonussteckverbinders für Hochspannungs-Starkstromkabel, wie er in Fig. 1 dargestellt ist. Erkennbar ist jeweils ein als Steckerteil 1a ausgebildetes inneres Kontaktelement 1 und ein als Buchsenteil 2a ausgebildetes äußeres Kontaktelement 2, sowie ein Rastnokkenring 18 mit einer Verriegelungsflanke 14, die über eine Nockenkuppe 18a zu einer Entriegelungsflanke 15 führt. Ein in einer Ringnut 6 des Buchsenteils 2a liegender Spiralfederring 3a wird beim Einstecken des Steckerteils 1a von der Verriegelungsflanke 14 des Rastnockenrings 18 zunächst auf ein Kompressionsprofil 17 gestaucht, kann sich jedoch hinter der Nockenkuppe 18a in einer Ringnut 6b des Steckerteils 1a wieder auf sein Verrastprofil 16 entspannen und dadurch in dieser Stellung verrasten. Während Fig. 5 diese Raststellung zeigt, befindet sich das Steckerteil 1a bei Fig. 6 in einer Zwischenstellung auf der Nockenkuppe 18a, bei der der Spiralfederring 3a stark gestaucht ist und anschließend entweder zu Entriegelung über die Entriegelungsflanke 15 oder zur Verriegelung über die Verriegelungsflanke 14 gleitet.5 to 7 show different variants of the contact area of an inner cone connector for high-voltage power cables, as shown in Fig. 1. In each case one can see an inner contact element 1 designed as a
Während bei den Darstellungen nach den Fig. 5 und 6 der Spiralfederring 3a so ausgelegt ist, daß er gleichzeitig für die Verriegelung und für die Kontaktierung sorgt, dient er bei der Ausführung nach Fig. 7 nur bzw. primär zur Verriegelung und überläßt die Kontaktierung einem weiteren Federring 3, der hier als Lamellenfederring 3b ausgebildet ist. Dies setzt jedoch voraus, daß der zu überbrückende Ringspalt 5 nur relativ kleine Toleranzen aufweist. Andernfalls wird man auch zur Kontaktierung einen entspechend dimensionierten, gut leitenden Spiralfederring 3a verwenden.5 and 6 of the
