Description
Die Erfindung betrifft eine Verbindung eines eine elektrische Leitung an einer Wand haltenden Druckteils einer Schelle, insbesondere einer Isolierstoffschelle, mit einer auf einen in der Wand eingelassenen, mit einem mit über die Wand vorspringendem Schraubenschaft versehenen Dübelbolzen aufschraubbaren, durch je einen Kragen an beiden Enden unverlierbar und drehbar in dem Druckteil eingelassenen Mutter.The invention relates to a connection of a pressure part holding an electrical line on a wall a clamp, in particular an insulating material clamp, with a one embedded in the wall, can be screwed on with a dowel bolt provided with a screw shaft protruding from the wall, Captive and rotatable embedded in the pressure part by a collar at both ends Mother.
Zur Verlegung elektrischer Leitungen an einer Wand finden vielfach Druckteile einer Schelle Verwendung, die auf einem in der Wand eingelassenen Dübel befestigt werden.To lay electrical lines on a wall, pressure parts of a clamp are often used, which are attached to a dowel embedded in the wall.
Zur Befestigung des Druckteils der Schelle dient dabei allgemein eine Mutter, die auf den über die Wand vorspringenden Schraubenschaft des Dübels aufgeschraubt wird.To attach the pressure part of the clamp generally a nut is used, which is on the Wall protruding screw shaft of the dowel is screwed on.
Bei derartigen bekannten Schellen ist es allgemein schwierig, die Mutter auf den Dübel aufzuschrauben.In such known clamps, it is generally difficult to screw the nut onto the dowel.
Die Mutter wird in der Regel lose mitgeliefert, und es ist für den Monteur zeitraubend und umständlich, insbesondere an schlecht zugänglichen Orten, die Mutter auf den Dübel zu bringen. Dabei geht die Mutter leicht verloren, wodurch, wenn nicht Ersatzmuttern vorhanden sind, die gesamte Schelle wertlos wird.The nut is usually supplied loose, and it is time-consuming and cumbersome for the installer to bring the nut onto the dowel, especially in poorly accessible places. That goes Nut easily lost, making the entire clamp worthless if spare nuts are not available will.
Es ist zwar schon bekanntgeworden, bei elektrischem Installationsmaterial metallische Muttern zu verankern.It has already become known to use metallic nuts for electrical installation material anchor.
Eine derartige Verankerung der Mutter erfolgt z. B. durch Umspritzen· oder Umgießen der Mutter mit Isolierstoffen. Bei dieser Befestigung der Mutter liegt diese aber unverdrehbar in dem Installationsteil, so daß dieses mit der Mutter auf ein Gewindeteil aufgeschraubt werden muß. Bei einer Anwendung dieser Mutternverankerung auf Druckteile von Schellen würde die Befestigung des Druckteils so umständlich und so erschwert, daß keine ausreichende Befestigung der elektrischen Leitungen erreicht würde.Such anchoring of the mother takes place, for. B. by overmoulding · or overmolding the mother with insulating materials. With this fastening of the nut, however, it is not rotatable in the installation part, so that this must be screwed onto a threaded part with the nut. When applying this Nut anchoring on pressure parts of clamps would make fastening the pressure part so cumbersome and so made difficult that sufficient fastening of the electrical lines would not be achieved.
Es ist aber auch schon bekanntgeworden, die Mutter drehbar, jedoch unverlierbar in elektrischem Installationsmaterial, z. B. in Abdeckkappen von Dosen, zu befestigen. Dabei wird die Mutter aus metallischem Spritzguß in eine öffnung des Installationssteils eingespritzt, wobei die Wandung der öffnung zuvor mit einem Überzug versehen wird, der nach Einspritzen der Mutter zu entfernen ist. Die Herstellung und Befestigung der Mutter bei Installationsteilen ist äußerst kompliziert und kostspielig, so daß sich diese Mutternbefestigung in der Praxis nicht durchsetzen konnte und infolgedessen auch bei Druckteilen für Schellen keine Anwendung gefunden hat.But it has already become known that the nut can be rotated, but cannot be lost in electrical installation material, z. B. in cover caps of cans to attach. The nut is made of metal Injection molding is injected into an opening of the installation part, the wall of the opening being previously with a coating is provided, which is to be removed after injecting the nut. The manufacture and fastening the nut in installation parts is extremely complicated and expensive, so that this nut fastening could not prevail in practice and consequently also with pressure parts for clamps found no application.
Der Erfindung liegt nun die Aufgabe zugrunde, eine Mutter in dem Druckteil einer Schelle durch
Verbindung eines eine elektrische Leitung an einer Wand haltenden Druckteils einer
Schelle, insbesondere einer Isolierstoffschelle, mit einer auf einen in der Wand
eingelassenen, mit einem mit über die Wand vorspringendem Schraubenschaft versehenen
Dübelbolzen aufschraubbaren, durch je einen Kragen an beiden Enden unverlierbar und drehbar in dem
Druckteil eingelassenen MutterThe invention is based on the object of providing a nut in the pressure part of a clamp by connecting a pressure part of a clamp holding an electrical line to a wall, in particular an insulating material clamp, with a screw shaft embedded in the wall with a screw shaft protruding over the wall provided dowel bolts can be screwed on, captive and rotatable in the by a collar at both ends

einen Kragen an beiden Enden unverlierbar und drehbar in einfacher Weise zu befestigen, um ein einfaches und schnelles Anschrauben des Druckteils der Schelle an einen in der Wand eingelassenen Dübel zu erreichen. to secure a collar at both ends captive and rotatable in a simple manner to a simple and to achieve quick screwing of the pressure part of the clamp to a dowel embedded in the wall.
Die Aufgabe wird dadurch gelöst, daß die in an sich bekannter Weise starre oder elastische Mutter mit dem in an sich bekannter Weise elastischen oder starren Druckteil so verbunden ist, daß einer der Kragen nach dem Durchdrücken der Mutter durch das mit kleineren Abmessungen als die Abmessungen des Kragens ausgebildete Mutternbett des Druckteils in einer öffnung des Druckteils liegt, die größer als die des Durchmessers des einen der beiden Kragen ist.The object is achieved in that the nut, which is rigid or elastic in a manner known per se is connected to the elastic or rigid pressure part in a known manner that one of the Collar after pushing the nut through with dimensions smaller than the dimensions of the collar formed nut bed of the pressure part lies in an opening of the pressure part which is larger than that of the diameter of one of the two collars.
Eine Ausführungsform ist dadurch gekennzeichnet, daß die Mutter als Hülse mit einem geschlossenen Kopfteil ausgebildet ist, der in an sich bekannter Weise einen Schlitz zum Ansetzen eines Schraubenziehers aufweist, und daß der Kragen sich nach dem Ende hin kegelig verjüngt.One embodiment is characterized in that the nut as a sleeve with a closed Head part is formed, which in a known manner has a slot for attaching a screwdriver has, and that the collar tapers conically towards the end.
Ein weiteres Merkmal besteht darin, daß die Mutter, ausgehend vom Kragen, in an sich bekannter Weise ein oder mehrmals in passender Länge federnd radial aufgeschlitzt ist.Another feature is that the nut, starting from the collar, is known per se Way one or more times is resiliently slit in a suitable length radially.
Ferner bestehen Merkmale darin, daß sich die Mutter mit axialem Spiel im Druckteil führt. Ferner kann das Mutternbett des Druckteils, z.B. eine Nabe,Furthermore, there are features that the nut leads with axial play in the pressure part. Further the nut bed of the pressure part, e.g. a hub,
