Description
Gegenstand der Erfindung ist eine Verbindungsklemme mit Klemmrollen für elektrische Leitungen, welche sich von den bekannten Klemmen dieser Art im wesentlichen dadurch unterscheidet, daß sie aus einer m't einer durchlaufenden Bohrung von zweckmäßig länglich rundem Querschnitt versehenen Muffe besteht, in welcher zwei auf gegenüberliegenden Seiten der Muffe angeordnete KlemmrollenThe invention is a connecting terminal with pinch rollers for electrical Lines which differ from the known terminals of this type essentially thereby distinguishes that it comes from a m't a continuous bore from expedient elongated round cross-section provided sleeve in which two on opposite Pinch rollers arranged on the sides of the sleeve
ίο derart gegeneinander versetzt gelagert sind, daß die beiden von entgegengesetzten Enden der Muffe her in deren Bohrung eingeführten, aneinanderliegenden Leitungsenden gemeinsam an zwei Stellen zwischen je einer Klemmrolle und der gegenüberliegenden Muffenwandung eingeklemmt werden. Dadurch wird einerseits eine elektrisch gut leitende Verbindung hergestellt, da die Leitungen an zwei Stellen sowohl unmittelbar aufeinander als auch gegen die Muffenwandungen gepreßt werden. Anderseits werden die Leitungen dadurch, daß sie nicht unmittelbar zwischen den beiden Rollen, sondern an beiden Klemmstellen zwischen einer Rolle und der Muffenwandung eingeklemmt werden, wesentlich geschont. Eine unmittelbare Einwirkung der Klemmrollen findet dabei immer nur am äußersten Ende einer jeden Leitung statt, während an der zweiten, weiter einwärts gelegenen Klemmstelle einer jeden Leitung der Druck der Klemmrolle durch das äußere Ende der anderen Leitung vermittelt wird, wodurch der Klemmdruck sich auf eine größere Fläche verteilt. Ein Abquetschen oder Knicken der Leitungen an ihren einwärts gelegenen Klemmstellen ist also ausgeschlossen. Die neue Verbindungsklemme eignet sich infolgedessen ganz besonders für aus einer Mehrzahl von dünnen Drähten bestehende Kabel.ίο are so offset from each other, that the two inserted from opposite ends of the sleeve into its bore, adjoining cable ends together at two points between each clamping roller and the opposite socket wall are clamped. This will on the one hand an electrically conductive connection is established because the lines are in two places are pressed both directly on top of one another and against the sleeve walls. On the other hand the lines are characterized by the fact that they are not directly between the two rollers, but between the two clamping points a role and the sleeve wall are clamped, significantly spared. A direct action of the pinch rollers takes place only at the extreme end of each line, while at the second, further inward terminal point of each line is the pressure of the Pinch roller is mediated by the outer end of the other line, whereby the Clamping pressure is distributed over a larger area. A squeezing or kinking of the Lines at their inwardly located terminal points are therefore excluded. The new connecting clamp as a result, it is particularly suitable for cables consisting of a plurality of thin wires.
Der Erfindungsgegenstand unterscheidet sich von den bekannt gewordenen gleichartigen Klemmen ferner dadurch, daß die walzenförmigen Klemmrollen in schräg zur Muffenachse verlaufenden, nach der Muffenmitte hin geneigten Schlitzen geführt und gelagert sind, wobei sie unter dem Einfluß zweier ihre Enden miteinander verbindenden Zugfedern stehen, welche bestrebt sind, die Klemmrollen in den Führungsschlitzen nach einwärts zu bewegen. Dadurch wird die Klemme wesentlieh vereinfacht und verbilligt.The subject of the invention differs from the similar ones that have become known Clamping further in that the roller-shaped clamping rollers in oblique to the sleeve axis running slots inclined towards the center of the socket are guided and supported, whereby they are under the influence of two tension springs connecting their ends to one another stand, which strive to move the pinch rollers inwards in the guide slots move. As a result, the clamp is simplified and made cheaper.

α ist der muffenartige Körper der Kupplung, welcher eine durchgehende, im Querschnitt länglich runde Lochung b besitzt, in welche die zu verbindenden Kabelenden c und d von entgegengesetzten Seiten her eingesteckt werden, so daß sie aufeinander zu liegen kommen! Zu beiden Seiten der Lochung b ist je eine Druckrolle e, und f in schräg zur Lochachse verlaufenden Schlitzführungen g und h angeordnet, welche Rollen die beiden aufeinanderliegenden Kabelenden c, d zwischen sich fassen und durch ihre Enden verbindende Zugfedern i, k gegen die Kabelenden gezogen werden. Dabei üben die Druckrollen e, f- infolge ihrer Schrägführung eine keilartige Wirkung auf die Kabelenden aus und pressen α is the sleeve-like body of the coupling, which has a continuous, elongated round hole b in cross section, into which the cable ends to be connected c and d are inserted from opposite sides so that they come to rest on one another! On both sides of the perforation b , a pressure roller e and f is arranged in slotted guides g and h running obliquely to the hole axis, which rollers hold the two cable ends c, d lying on top of one another and pull springs i, k connecting their ends against the cable ends will. The pressure rollers e, f- exert a wedge-like effect on the cable ends due to their inclined guidance and press

In the example, the rollers β, f are also equipped with an annular groove in which the cable ends are inserted in order to achieve a larger contact area between the rollers and the cable.
