Description
Einrichtung zur Verbindung mehrerer Leitungen, insbesondere für eine dreiphasige Erdungsvorrichtung Die Erfindung betrifft eine Einrichtung zur Ver- bindung mehrerer Leitungen, insbesondere für eine dreiphasige Erdungsvorrichtung,
mit mehreren mitein- ander verbundenen Kabelschuhen. Durch eine solche Einrichtung werden vorzugsweise die drei zu den zu erdenden Phasen führenden Leitungen und die zur Erde führende Leitung vereinigt. Mit einer solchen Erdungsvorrichtung werden somit die drei Phasen einer Starkstromleitung kurzgeschlossen und: geerdet.
Bei den im Betrieb auftretenden starken Bean spruchungen kommt es vor, dass die Kabelschuhe sich zueinander verdrehen, wodurch ihre durch den Abstand der Phasenleiter gegebene winkelgerechte Stellung nicht mehr beibehalten wird und sogar die die Kabelschuhe gegebenenfalls zusammenhaltende Schraube gelockert wird.
Zur Vermeidung dieses Nachteils schlägt die Er findung vor, dass die Löcher der Kabelschuhösen mit gezahnten Rändern versehen sind und dass ein. Zylin derstück vorgesehen ist, dessen Aussenumfang mit in Längsrichtung verlaufenden Zähnen versehen ist, die in die Zähne der Ränder der Löcher der Kabel schuhösen gleitend: passen.
Die Kabelschuhe können durch eine Schraube zusammengehalten sein, wobei gemäss einer Weiterausbildung der Erfindung das Zylinderstück als eine die Schraube umgebende Hülse ausgebildet ist. Durch diese Ausbildung wird erreicht, dass die über die Hülse geschobenen Kabel schuhe sich in ihrer Winkelstellung zueinander nicht mehr verschieben können. Die Schraube hält nur mehr die Kabelschuhe zusammen, d. h. sie wird nicht auf Drehung beansprucht, wodurch ein Lösen; ver hindert wird.
Durch die Vielzahl der Zähne an der Hülse und an den Rändern der Löcher der Kabelschuhe ist es möglich, die Stellung .der Kabelschuhe zueinander auch um kleine Winkel zu ändern.
Eine beispielhafte Ausführungsform der Erfin dung ist in der Zeichnung dargestellt, und zwar sind Fig. leine Aufsicht auf leine Verbindungseinrich- tung, wobei der Schraubenkopf und die Unterlags- scheibe weggelassen sind,
Fig. 2 ein. Schnitt durch die Verbindungseinrich- tung nach der Linie II-II der Fig. 1 und Fig. 3 eine vergrösserte Stirnansicht der Hülse. Die Verbindungseinrichtung weist die vier Kabel schuhe 1 bis 4 auf, von denen die Kabelschuhe 1 his 3 vorzugsweise für die zu den drei Phasen führenden Leitungen und der Kabelschuh 4 für die zur Erde führende Leitung vorgesehen sind.
Die Löcher in, den Kabelschuhösen 5 sind mit gezahnten Rändern 6 versehen. Die Kabelschuhe werden durch die, Schraube 7 zusammengehalten, auf die eine Mutter 8 aufge schraubt wird, wobei Unterlagsscheiben 9 verwendet sind.
Die Schraube 7 ist von einer Hülse 10 umgeben, deren Aussenumfang mit achtzehn Zähnen 11 verse- hen ist, die gleitend in die Zähne der Ränder der Löcher der Kabelschuhösen passen. Der z. B. zwi schen den Kabelschuhen 1 und 2 bestehende Winkel von 60 kann gewünschtenfalls geändert werden, indem die Einrichtung auseinandergenommen wird und die Hülse nach gegenseitigem Verdrehen der Ka belschuhe wieder eingesetzt wird.
Device for connecting multiple lines, in particular for a three-phase grounding device The invention relates to a device for connecting multiple lines, in particular for a three-phase grounding device,
with several interconnected cable lugs. Such a device preferably combines the three lines leading to the phases to be earthed and the line leading to earth. With such a grounding device, the three phases of a power line are short-circuited and: grounded.
With the strong stresses occurring during operation, it happens that the cable lugs twist with respect to one another, as a result of which their angular position given by the spacing of the phase conductors is no longer maintained and even the screw that may hold the cable lugs together is loosened.
To avoid this disadvantage, the invention proposes that the holes of the cable lug eyes are provided with toothed edges and that a. Zylin derstück is provided, the outer circumference of which is provided with longitudinally extending teeth that slide shoe eyes into the teeth of the edges of the holes of the cable: fit.
The cable lugs can be held together by a screw, wherein, according to a further development of the invention, the cylinder piece is designed as a sleeve surrounding the screw. This design ensures that the cable shoes pushed over the sleeve can no longer move in their angular position to one another. The screw only holds the cable lugs together, i.e. H. it is not subjected to rotation, causing loosening; is prevented.
Due to the large number of teeth on the sleeve and on the edges of the holes in the cable lugs, it is possible to change the position of the cable lugs to one another by small angles.
An exemplary embodiment of the invention is shown in the drawing, namely: FIG. 1 is a plan view of a connecting device, the screw head and the washer being omitted,
Fig. 2 a. Section through the connecting device along the line II-II in FIGS. 1 and 3, an enlarged end view of the sleeve. The connecting device has the four cable shoes 1 to 4, of which the cable lugs 1 to 3 are preferably provided for the lines leading to the three phases and the cable lug 4 for the line leading to earth.
The holes in the cable lug eyes 5 are provided with toothed edges 6. The cable lugs are held together by the screw 7, onto which a nut 8 is screwed, with washers 9 being used.
The screw 7 is surrounded by a sleeve 10, the outer circumference of which is provided with eighteen teeth 11, which slide into the teeth of the edges of the holes in the cable lug eyes. The z. B. between tween the cable lugs 1 and 2 existing angle of 60 can be changed if desired by disassembling the device and the sleeve is reinserted after mutual rotation of the Ka belschuh.
