Abstract

1. Swivelling and laterally displaceable plug-in connection for the connection of a transformer winding to a rigidly guided plug component at the end of a lever arm which carries out imposed swivelling movements characterised in that a plug socket (2) which accommodates the plug pin (1) is arranged in a sleeve (3) mounted in a universal joint, behind the universal joint in the direction of insertion of the plug pin (1) and that the sleeve (3) can be laterally displaced across axis in the joints of the universal joint from a centre position.

Description

Die Erfindung betrifft eine Steckverbindung zum Anschluß einer Trans forma torwicklung an ein starr geführtes Steckerteil am Ende eines aufgezwungene Schwenkbewegungen ausführenden Hebelarms.The invention relates to a plug connection for connecting a trans forma gate winding to a rigidly guided plug part at the end of an imposed lever arm.

Innerhalb von elektrischen Geräten, beispielsweise innerhalb von Transformatoren müssen auch an unzugänglichen Stellen lösbare elektrische Kupplungen, beispielsweise beim Anschluß von Wicklungsausleitungen an Durchführungen, hergestellt werden. Derartige Kupplungen sind an betriebsbereiten Geräten unzugänglich und müssen im Betriebszustand häufig Bewegungen aufnehmen, ohne daß dabei wesentliche mechanische Kräfte übertragen werden dürfen.Within electrical devices, for example within transformers, detachable electrical couplings must also be produced in inaccessible places, for example when connecting winding leads to bushings. Such couplings are inaccessible on ready-to-use devices and often have to absorb movements in the operating state without substantial mechanical forces being transmitted.

Dies ist beispielsweise beim Anschluß von starren Rohrgaskabeln an Transformatoren der Fall. Die in den Rohrkapselungen auftretenden Wärmeausdehnungen bewirken Pendelbewegungen an den Durchführungen, da die Kabel üblicherweise im Winkel zu den Durchführungsachsen an diese herangeführt sind. Die auf der Innenseite des Transformators häufig als Stecker ausgeführten Enden der Durchführungen greifen in Steckbuchsen ein, von denen diese Pendelbewegungen aufgenommen werden müssen, ohne die Wicklungsausleitungen oder aber die Stecker mit wesentlichen mechanischen Kräften zu belasten. Zu diesem Zweck ist bei einer bekannten Anordnung die Steckerbuchse in einer quer zur Steckerachse verschiebbaren Platte gehalten. Infolge relativ großen Lagerspiels kann diese Platte auch geringfügige Schwenkbewegungen ausführen. Diese Lösung ist jedoch unbefriedigend, weil die Größe der zulässigen Schwenkbewegungen sehr klein ist und deswegen unkontrolliert größere mechanische Belastungen an der Steckverbindung auftreten.This is the case, for example, when connecting rigid pipe gas cables to transformers. The thermal expansions occurring in the pipe encapsulation cause pendulum movements on the bushings, since the cables are usually guided to the bushing axes at an angle to them. The ends of the bushings, which are often designed as plugs on the inside of the transformer, engage in sockets, from which these oscillating movements have to be absorbed, without stressing the winding rejects or the plugs with significant mechanical forces. For this purpose, in a known arrangement the plug socket is held in a plate which can be moved transversely to the plug axis. As a result of relatively large bearing play, this plate can also perform slight swiveling movements. However, this solution is unsatisfactory because the size of the permissible pivoting movements is very small and therefore inconclusive trolled greater mechanical loads occur on the connector.

Der Erfindung liegt daher die Aufgabe zugrunde eine Steckverbindung für große Ströme zu schaffen, die in Transformatoren an im Betriebszustand unzugänglichen Stellen einsetzbar ist, und erzwungene Pendelbewegungen und Verschiebungen aufnehmen kann.The invention is therefore based on the object of providing a plug-in connection for large currents which can be used in transformers at locations which are inaccessible in the operating state and which can accommodate forced pendulum movements and displacements.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß eine den Steckerstift aufnehmende Steckerbuchse in einer in Kreuzgelenken gelagerten Hülse in Einschubrichtung des Steckerstiftes hinter den Kreuzgelenken angeordnet ist und daß die Hülse quer zu ihrer Achse an beiden Kreuzgelenken aus einer Mittenlage heraus nach beiden Seiten verschiebbar ist. Dabei dient als Kuppelstück zwischen zwei Lagerzapfenpaaren der Kreuzgelenke ein Ring in den von innen ein von der Hülse getragenes Lagerzapfenpaar eingreift und der nach außen in Spalte zwischen den vom Gehäuse getragenen Lagerzapfen des zweiten Lagerzapfenpaares und diesen zugeordneten, gehäusefesten Anschlägen eintaucht, wobei die Lagerzapfen des zweiten Lagerzapfenpaares in Nuten des Ringes liegen.According to the invention, this object is achieved in that a socket receiving the plug pin is arranged in a sleeve mounted in universal joints in the direction of insertion of the connector pin behind the universal joints and that the sleeve is displaceable transversely to its axis on both universal joints from a central position to both sides. In this case, a ring serves as a coupling piece between two pairs of trunnions of the universal joints, into which a pair of trunnions carried by the sleeve engages from the inside and which plunges outwards into gaps between the trunnions of the second pair of trunnions carried by the housing and the associated, fixed stops, the trunnions of the second Pair of trunnions lie in the grooves of the ring.

Nach vorteilhaften Ausgestaltungen der Erfindung ist vorgesehen, daß die Anschläge lösbar im Gehäuse befestigt sind und daß die Hülse über flexible Kupferbänder an elektrischer Spannung liegt, wobei die Hülse über ein besonderes Band galvanisch mit dem als Abschirmelektrode ausgebildeten Gehäuse verbunden ist.According to advantageous embodiments of the invention it is provided that the stops are detachably fastened in the housing and that the sleeve is connected to electrical voltage via flexible copper strips, the sleeve being galvanically connected to the housing designed as a shielding electrode via a special strip.

Nach weiteren Ausgestaltungen der Erfindung besteht die Steckerbuchse aus einer Vielzahl von parallel zur Steckerstiftachse angeordneten federnden Kontaktlamellen und ist die Steckerbuchse durch eine von der Einführungsseite des Steckerstiftes in die Hülse eingeschraubten Führungsbuchse mit trichterförmiger Öffnung in der Hülse gehalten.According to further embodiments of the invention, the plug socket consists of a plurality of resilient contact lamellae arranged parallel to the plug pin axis and the plug socket is held in the sleeve by a guide socket with a funnel-shaped opening screwed into the sleeve from the insertion side of the plug pin.

Die erfindungsgemäße Steckverbindung ist sehr vorteilhaft, denn sie gestattet aufgrund der kardanischen Aufhängung der Steckerbuchse Pendolbewegungendes fest in sie eingreifenden Steckerstiftes ohne dadurch größere mechanische Belastungen an den beteiligten Bauteilen hervorzurufen. Außerdem erleichtert sie durch die Anordnung der Steckerbuchse in Einschubrichtung des Steckeratiftes hinter den Kreuzgelenken das Einführen des Steckerstiftes, weil sich die Anordnung zwangsweise selbst zentriert.The plug-in connection according to the invention is very advantageous because it allows the plugs to be suspended due to the gimbal socket pendulum movement of the connector pin which engages firmly without causing greater mechanical loads on the components involved. In addition, the arrangement of the plug socket in the insertion direction of the plug pin behind the universal joints makes it easier for the plug pin to be inserted because the arrangement is forcibly centered.

Ein Ausführungsbeispiel der Erfindung wird anhand einer Zeichnung näher erläutert. Dabei zeigt

  • Figur 1 einen Längs- und
  • Figur 2 einen Querschnitt durch eine Steckverbindung.
An embodiment of the invention is explained in more detail with reference to a drawing. It shows
  • Figure 1 is a longitudinal and
  • Figure 2 shows a cross section through a plug connection.

Ein in nicht näher dargestellter Weise starr geführter Steckerstift 1 ist in eine Steckerbuchse 2 eingeführt. Die Steckerbuchse 2 wird von einer in Kreuzgelenken gelagerten Hülse 3 geführt und gehalten, wobei zur Erleichterung des Einfädelns des Steckerstiftes 1 in die Steckerbuchse 2 auf der Einführungsseite der Hülse 3 eine FUhrungsbuchse 4 mit trichterförmiger Öffnung vorgesehen ist.A plug pin 1, which is rigidly guided in a manner not shown in detail, is inserted into a plug socket 2. The socket 2 is guided and held by a sleeve 3 mounted in universal joints, a guide socket 4 with a funnel-shaped opening being provided on the insertion side of the socket 3 to facilitate the threading of the plug pin 1 into the socket 2.

Die in die Hülse 3 fest eingeschraubte Führungsbuchse 4 dient gleichzeitig zur Sicherung der Steckerbuchse 2 gegen axiale Verschiebungen.The guide bushing 4, which is firmly screwed into the sleeve 3, also serves to secure the connector bushing 2 against axial displacements.

Die Hülse 3 trägt zwei gegeneinander um 180° versetzte Lagerzapfen 5 die verschiebbar in Bohrungen eines Ringes 6 eingreifen. In dem Ring 6 sind um 90° gegen die die Lagerzapfen 5 aufnehmenden Bohrungen versetzt nicht näher bezeichnete Nuten vorgesehen, die Lagerzapßen 7 umfassen, in deren Achsrichtung der Ring 6 verschiebbar ist. Sowohl die Lagerzapfen 5 als auch die Lagerzapfen 7 sind oberhalb des Reibungsschwerpunktes zwischen dem Steckerstift 1 und der Steckerbuchse 2 angeordnet, so daß diese beim Einführen des Steckerstiftes 1 zwangsweise zentriert wird. Die Lagerzapfen 7 sind im übrigen fest in einem gleichzeitig als Abschirmelektrode dienenden Gehäuse 8 befestigt.The sleeve 3 carries two bearing journals 5 which are offset by 180 ° and which can be slidably engaged in the bores of a ring 6. In the ring 6 are offset by 90 ° against the bores receiving the journals 5 not provided grooves, which comprise bearing journals 7, in the axial direction of which the ring 6 is displaceable. Both the bearing pin 5 and the bearing pin 7 are arranged above the center of gravity between the plug pin 1 and the socket 2, so that this is forcibly centered when the plug pin 1 is inserted. The bearing pins 7 are otherwise fixed in a housing 8 which also serves as a shielding electrode.

Der elektrische Anschluß der Steckerbuchse 2 erfolgt über die Hülse 3, an die durch eine Öffnung im Boden des Gehäuses 8 herangeführte flexible Kupferbänder 9 angeschlossen sind. Über ein besonderes,verhältnismäßig schwaches Kupferband 10 ist die Hülse 3 auch galvanisch mit dem Gehäuse 8 verbunden.The electrical connection of the socket 2 is made via the Sleeve 3, to which flexible copper strips 9 which are brought through an opening in the bottom of the housing 8 are connected. The sleeve 3 is also galvanically connected to the housing 8 via a special, relatively weak copper strip 10.

Nach Befestigung der flexiblen Kupferbänder 9 und 10 an der Hülse 3 wird diese zusammen mit dem auf die Lagerzapfen 5 geschobenen Ring 6 in das Gehäuse 8 eingeführt bis die nicht näher bezeichneten Nuten auf der Unterseite des Ringes 6 die Lagerzapfen 7 wenigstens teilweise umfassen. In dieser Lage wird der Ring 6 von lösbar an der Wand des Gehäuses 8 befestigten Anschlägen 11 gehalten. Die als Winkel ausgebildeten Anschläge 11 werden von Muttern 12 am Gehäuse 8 gehalten und führen mit ihrem freien Schenkel den Ring 6 so, daß dieser in Richtung der Lagerzapfen 7 verschiebbar bleibt und außerdem Schwenkbewegungen auf dem Umfang der Lagerzapfen 7 ausführen kann.After the flexible copper strips 9 and 10 have been fastened to the sleeve 3, the latter is inserted into the housing 8 together with the ring 6 pushed onto the bearing pin 5 until the not-specified grooves on the underside of the ring 6 at least partially surround the bearing pin 7. In this position, the ring 6 is held by stops 11 which are detachably fastened to the wall of the housing 8. The angular stops 11 are held by nuts 12 on the housing 8 and guide the ring 6 with their free leg so that it remains displaceable in the direction of the journal 7 and can also perform pivoting movements on the circumference of the journal 7.

Durch entsprechende Ausführungen des Gehäuses 8 und die Anbringung von mehr als einem Paar Lagerzapfen 7 an den Gehäuseseitenwänden sind auch mehrpolige Steckverbindungen gemäß der erfindungsgemäßen Anordnung ausführbar.By appropriate designs of the housing 8 and the attachment of more than one pair of bearing pins 7 on the housing side walls, multi-pole plug connections can also be carried out according to the arrangement according to the invention.
