Abstract
Description
Die Erfindung betrifft eine Schlauchkupplung mit einer Tülle, über die das Ende des Schlauches geschoben und mittels einer Schlauchklemme darauf lösbar auf ihr befestigt ist, und mit einem sich axial an die Tülle anschließenden, mit ihr einstückigen Verbindungsstück.The invention relates to a hose coupling with a Spout over which the end of the hose is slid and attached to it releasably by means of a hose clamp and with an axially adjoining the spout, with her one-piece connector.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Schlauchkupplung dahingehend zu verbessern, daß zur Vermeidung elektrostatischer Aufladung des Schlauches eine durchgehende elektrische Leitfähigkeit zwischen einer im Schlauch vorhandenen Drahteinlage und der Schlauchkupplung geschaffen wird. Bei den bisher bekannten Schlauchkupplungen ist dies nicht gewährleistet. Dadurch kann es aufgrund der erwähnten elektrostatischen Aufladung der Schläuche zu Funkenbildung bei einer Entladung kommen, die in bestimmten Bereichen, in denen sich feuergefährliche oder explosive Stoffe befinden, zu einer Initialzündung mit nachfolgender Explosion oder Verpuffung kommen kann.The invention has for its object the generic Hose coupling to improve that Avoid electrostatic charging of the hose continuous electrical conductivity between an im Hose existing wire insert and the hose coupling is created. In the previously known hose couplings this is not guaranteed. Because of this, it can mentioned electrostatic charging of the hoses Sparking occurs when a discharge occurs in certain Areas where there are flammable or explosive Substances are, to an initial spark with subsequent Explosion or deflagration can occur.
Zur Lösung dieser Aufgabe wird bei der gattungsgemäßen Schlauchkupplung erfindungsgemäß vorgeschlagen, daß am Übergang von der Tülle zum Verbindungsstück ein Ring vorgesehen ist, der einen in Richtung auf das Ende des Schlauches gerichteten gezackten Rand aufweist, dessen Durchmesser gleich dem der Drahteinlage in dem Schlauch ist. Bei dem Ring mit gezacktem, gezahntem oder mit Dornen versehenen Rand kann es sich um ein loses Teil, also um einen separaten Ring handeln, der über die Tülle bis zu einem Anschlag am Übergang zum Verbindungsstück geschoben wird. Es kann sich aber auch um eine Schulter handeln, die am Übergang zwischen Tülle zum Verbindungsstück gebildet ist und die die Zacken, Zähne oder Dornen trägt.To solve this problem is the generic Hose coupling proposed according to the invention that on A ring transition from the spout to the connector is provided, one towards the end of the Has hose directed serrated edge, the Diameter equal to that of the wire insert in the hose is. The ring with serrated, serrated or thorns provided edge can be a loose part, that is act a separate ring that extends over the spout pushed a stop at the transition to the connector becomes. But it can also be a shoulder, at the transition between the spout and the connector is formed and which carries the prongs, teeth or thorns.
Beim Aufschieben des Schlauchendes auf die Tülle wird dieses so weit über die Tülle geschoben, bis sich die Zähne, Zacken oder Dornen in die Stirnfläche des Schlauches bohren und dort eine elektrisch leitende Verbindung mit der Drahteinlage im Schlauch herstellen. Nun kann elektrische Ladung aus dem Schlauch über die Kupplung zur Erde fließen, so daß sich kein Spannungspotential aufbauen kann, daß zu einer unbeabsichtigten Zündfunkenbildung führt.When pushing the hose end onto the spout this so far over the spout until the Teeth, serrations or thorns in the end face of the hose drill and there with an electrically conductive connection the wire insert in the hose. Well now electrical charge from the hose via the coupling to Earth flow so that no voltage potential build up can cause accidental sparking leads.

Fig. 3 eine Ansicht eines gezackten Ringes und Fig. 3 is a view of a serrated ring and
Fig. 4 die zugehörige Seitenansicht zu Fig. 3. Fig. 4 shows the corresponding side view of FIG. 3.
Die Schlauchkupplung besteht aus der Tülle 1, über die das Ende des Schlauches 2 geschoben ist. Der Schlauch 2 hat eine Stahldrahteinlage 3, wie sie zur Verstärkung von Hochdruckschläuchen üblich ist. Die Tülle 1 setzt sich axial in das Verbindungsstück 4 fort. Es handelt sich im dargestellten Ausführungsbeispiel um ein Schraubverbindungsstück zum Anschluß an ein Gerät. The hose coupling consists of the nozzle 1 , over which the end of the hose 2 is pushed. The hose 2 has a steel wire insert 3 , as is customary for reinforcing high-pressure hoses. The nozzle 1 continues axially into the connecting piece 4 . It is in the illustrated embodiment, a screw connector for connection to a device.
Das Ende des Schlauches 2 wird auf der Tülle 1 durch eine Schlauchklemme 5 geklemmt. Diese ist üblicherweise an einem Ringbund 6 der Schlauchkupplung angelenkt.The end of the hose 2 is clamped on the spout 1 by a hose clamp 5 . This is usually articulated on an annular collar 6 of the hose coupling.
Am Übergang von der Tülle 1 zum Verbindungsstück 4 ist nun ein Ring 7 angeordnet, an dessen Außenrand Zacken 8 angeformt sind. Dabei entspricht der Außendurchmesser des Rings und damit der Diametralabstand der Zacken 8 dem Durchmesser der Drahteinlage 3 in dem Schlauch 2. Beim Aufschieben des Endes des Schlauches 2 auf die Tülle 1 bohren sich die Zacken 8 in die Stirnfläche des Schlauches 1 und treffen dort auf die Drahteinlage 3, mit der sie eine elektrisch leitende Verbindung herstellen. Über die Zacken 8 des Ringes 7 kann nun Strom aus der Drahteinlage 3 in die Schlauchkupplung fließen und umgekehrt. Damit ist eine Erdung des Schlauches 2 möglich.At the transition from the spout 1 to the connecting piece 4 , a ring 7 is now arranged, on the outer edge of which prongs 8 are formed. The outer diameter of the ring and thus the diametrical spacing of the prongs 8 corresponds to the diameter of the wire insert 3 in the hose 2 . When the end of the hose 2 is pushed onto the spout 1 , the prongs 8 drill into the end face of the hose 1 and meet there with the wire insert 3 , with which they produce an electrically conductive connection. Current can now flow from the wire insert 3 into the hose coupling and vice versa via the prongs 8 of the ring 7 . This makes it possible to ground the hose 2 .
Anstelle des zackenbesetzten Ringes 7 kann auch eine Ausführung gewählt werden, bei der die Zacken 8 unmittelbar zum Beispiel an einer Schulter 9 am Übergang von der Tülle 1 zu dem Verbindungsstück 4 angeformt sind. Es entfällt damit ein separates Teil, wie es der Ring 7 darstellt. Andererseits ist die fertigungstechnische Herstellung eines Ringes 7 mit Zacken 8 billiger als die Anformung von Zacken an der Schlauchkupplung. Von der technischen Funktion her sind jedoch beide Ausführungen äquivalent.Instead of the toothed ring 7 , an embodiment can also be selected in which the teeth 8 are formed directly on, for example, a shoulder 9 at the transition from the spout 1 to the connecting piece 4 . A separate part, as represented by the ring 7 , is thus omitted. On the other hand, the manufacturing of a ring 7 with prongs 8 is cheaper than the formation of prongs on the hose coupling. In terms of the technical function, however, both versions are equivalent.
