Description

Beim Zusammenstecken des Steckers 2 und der Hülse 1 paßt der Steckerrohrteil 9 zunächst frei in das vordere Ende des Hülsenrohrteiles 4 hinein. Die Vorderenden 15 der Kantenschlitze 12 und 13 des Steckerteiles greifen in den einander entfernten Seiten der nach innen umgebogenen Flansche 7 an, und wenn der Steckerteil weiter in den Hülsenteil eingesteckt wird, so bewirken die Flansche 7 beiderseits des sich verjüngenden Schlitzes 14 einen mit Keilwirkung verbundenen Kontakt. Der Hülsenrohrteil 4 wird mehr und mehr um den Steckerrohrteil 9 fest herumgebogen, wobei eine Kontaktfläche sich zwischen der Innenfläche des Hülsenrohrteiles und der Außenfläche des Steckerrohrteiles an einer Stelle, welche im Abstand von den Flanschen 7 liegt, ergibt. Wenn in geeigneter Weise der Innendurchmesser und der Außendurchmesser des Steckerteiles und des Hülsenteiles gewählt sind, und auch die Abmessungen des Schlitzes 14 und der Abstand der nicht einander zugewendeten Seiten der Flansche 7 gewählt sind, so wird der den elektrischen Kontakt bewirkende Hülsenrohrteil 4 fest um den den elektrischen Kontakt bewirkenden Steckerrohrteil 9 gebogen, so daß sich praktisch an der gesamten Mantelfläche ein elektrischer Kontakt ergibt, wobei die Kontaktflächen, die durch einen Faßreifen unter Spannung und entsprechendem hohen Kontaktdruck miteinander gehalten werden.When plugging the plug 2 and the sleeve 1 together, the plug tube part 9 initially fits freely into the front end of the sleeve tube part 4 into it. The front ends 15 of the edge slots 12 and 13 of the Plug part engage in the mutually distant sides of the inwardly bent flanges 7, and when the plug part is inserted further into the sleeve part, the flanges 7 act on both sides of the tapered slot 14 is a wedge-acting contact. The sleeve tube part 4 is more and more firmly bent around the plug tube part 9, with a contact surface between the inner surface of the sleeve tube part and the outer surface of the plug tube part at one point, which is at a distance from the flanges 7, results. If appropriate the inside diameter and the outer diameter of the plug part and the sleeve part are selected, and also the dimensions of the slot 14 and the distance between the non-facing sides of the flanges 7 are selected, the sleeve tube part 4 causing the electrical contact is fixed around the electrical one Contact causing plug tube part 9 bent, so that practically on the entire surface area an electrical contact results, with the contact surfaces by a barrel hoop underneath Tension and corresponding high contact pressure can be maintained with each other.

Bei der Ausführungsform gemäß F i g. 4 handelt es sich insofern um eine Abwandlung, als an der dem Schlitz 14A gegenüberliegenden Seite der Steckerrohrteil 9 eine Rippe 16 aufweist. Die Rippe 16 erstreckt sich in Längsrichtung des Steckerrohrteiles 9 und wird durch eine nach innen gerichtete Vertiefungsnut des Steckerrohrteiles 9 gebildet, so daß sich eine Nut 17 an der der Rippe 16 gegenüberliegenden Seite ergibt. Diese Nut bzw. diese Rippe erhöht die Elastizität des Steckerrohrteiles gegenüber in Richtung des Umfanges wirkenden Kräften, die sich dadurch ergeben, daß der Schlitz des Steckerrohrteiles Kontakt mit den Flanschen 7 bewirkt. Die Kanten des Steckerrohrteiles 9 an dem Schlitz 14A können parallel verlaufen, da die wesentliche Keilwirkung durch die erweiterte Eintrittsöffnung 15 in F i g. 2 bedingt ist.In the embodiment according to FIG. 4 is a modification insofar as the plug tube part 9 has a rib 16 on the side opposite the slot 14A. The rib 16 extends in the longitudinal direction of the connector tube part 9 and is formed by an inwardly directed recess groove of the connector tube part 9, so that a groove 17 results on the side opposite the rib 16. This groove or this rib increases the elasticity of the plug tube part with respect to forces acting in the direction of the circumference, which result from the fact that the slot of the plug tube part makes contact with the flanges 7. The edges of the plug tube part 9 at the slot 14A can run parallel, since the essential wedge effect through the enlarged inlet opening 15 in FIG. 2 is conditional.

Gegebenenfalls kann zusätzlich zu der Verjüngung des Schlitzes 14 des Steckerteiles der Schlitz 6 des Hülsenteiles sich nach innen verjüngen. Es können auch mehrere Rippen 16 an dem Steckerteil vorgesehen sein.Optionally, in addition to the tapering of the slot 14 of the plug part, the slot 6 of the Sleeve part taper inwards. A plurality of ribs 16 can also be provided on the plug part be.

1. Electrical plug-in coupling, consisting of such that the plug slot or the socket one Longitudinally slotted tubular socket with 5 flange opposite surface parts of the plug inwardly bent, forming flanges or the socket when inserting the plug into the Slotted edges and brought into contact with one another under pressure from a longitudinally slotted socket tubular connector, thereby identifying:

draws that in the relaxed state of the A plug-in coupling according to the invention has the Outer diameter of the longitudinally protected tube io advantage that both the socket and the plug shaped plug (2) smaller than the inner diameter - in a simple manner from punched, bent sheet metal knife the longitudinally slotted tubular socket parts can be produced .sind. In the inventive (4) and the plug slot edges (11) on the plug-in coupling take effect when the leading end a greater distance than the plug the elasticity of the slotted tubular facing away from each other flange surfaces (6) of the socket 15 by inserting the plug into tubular socket (1) and on the other hand the socket initially the plug as a result of contact Have a distance towards the end that is less of its slot edges with those facing away from each other than the distance between said flange surfaces (6) surface parts of the socket flanges is spread apart from each other, in such a way that the plug slot and the tubular, which is also slotted (11) or the socket flange (6) opposite 20 socket elastically yields.
