Description

Mantelklemme für elektrische Leitungen Die Erfindung hat eine Verbesserung an jenen Mantelklemmen fürelektrische Leitungen zum Gegenstand, bei welchen der als Überwurfmutter ausgebildete Mantel und das mit ihm drehbar verbundene Druckstück gegenüber dem Fußstück durch eine Schraubensicherung verriegelt wird. Diese d12 Funkenbildung verhindernde Verriegelung für Mantelklemmen .st insbesondere bei @elektrischen Einrichtungen in Kohlenbergwerken oder in explosionsgefährdeten Räumen von großer Wichtigkeit. Durch die Verriegelung sollen weiter aber auch die Ausmaße gegenüber den bereits vorhandenen Mantelklemmien nicht vergrößert werden, so daß die neue Klemme ohne weiteres in bereits vorhandene Anlagen und Geräte eingebaut werden kann.Jacket Clamp for Electrical Wires The invention has an improvement on those sheath terminals for electrical cables, in which the formed as a union nut jacket and the pressure piece rotatably connected to it is locked against the base by a screw locking device. This d12 Interlocking to prevent sparking for jacket terminals .st especially for @electrical ones Facilities in coal mines or in potentially explosive areas of large Importance. The interlocking should also keep the dimensions opposite the existing jacket clamps are not enlarged, so that the new Terminal can be easily installed in existing systems and devices.

Es sind nun bereits Mantelklemmern. bekannt, bei welchen im- Boden der Mantelhaube mehrere Schrauben in einem Kreis angeordnet sind, derart, daß je zwei Schrauben sich diametral gegenüberstehen. Diese Art der Verriegelung ist jedoch teuer und ,auch nicht unbedingt wirksam, insbesondere dann, wenn das Druckstück mit seiner schmalen Stirnseite zwischen die Schrauben zu liegen kommt, so daß diese gar nicht oder nur ungenügend mit dem Druckstück in Eingriff gelangen. Außerdem ist es bei kleineren und mittleren Mantelklemmen, welche nur einen Durchmesser bis zu i,5 mm aufweisen, fabrikationstechnisch nicht mägUch, in dem Boden des Klemmenmantels vier bis sechs Gewindebohrungen zum Einführen der Madendruckschrauben anzubringen und außerdem noch einen Querschlitz zum Einsetzen eines Schraubenziehers- zum Festziehen des. Klemmenmantels ,auf dem Fußstück vorzusehen.There are already jacket clamps. known which im- soil the jacket hood several screws are arranged in a circle, so that each two screws are diametrically opposed. This type of locking is however expensive and not necessarily effective, especially if the pressure piece comes to rest with its narrow face between the screws, so that these do not get into engagement with the pressure piece at all or only insufficiently. aside from that it is with smaller and medium-sized jacket clamps, which only have a diameter of up to to 1.5 mm, technically not possible, in the bottom of the terminal jacket four to six threaded holes for inserting the grub screw and also a transverse slot for inserting a screwdriver for tightening Des. Clamp jacket to be provided on the foot piece.

Die Nachteile der bekannten Mantelklemmen werden nun durch die Erfindung dadurch behoben, daß das Druckstück unterhalb des Mantelbodens als Scheibe ausgebildet ist.The disadvantages of the known jacket clamps are now eliminated by the invention remedied by the fact that the pressure piece is designed as a disc below the casing base is.

Eine derartige mit Verriegelung ausgestattete Mantelklemme ist in den Abb. i bis 3 der Zeichnung in einer Ausführungsform veranschaulicht, und zwar zeigen die Abb. i und 2 zwei im rechten Winkel zueinander stehende lotrechte Schnitte und die Abb. 3 die Draufsicht auf die Mantelklemme.Such a jacket clamp equipped with a lock is shown in FIG Figs. i to 3 of the drawing illustrates in one embodiment, namely Figs. i and 2 show two perpendicular sections at right angles to one another and Fig. 3 is a plan view of the jacket clamp.

Die auf das Fußstück/ aufgeschraubte und als Überwurfmutter ausgebildete Mantelhaubea ist mit dem plattenförmigen Druckstück c durch einen Nietbolzen b drehbar verbunden. Gemäß der Erfindung ist nun der unmittelbar unter dem Mantelboden gelegene Teil des Druckstückes c als Scheibe s ausgebildet; so daß die beiden in Gewindebohrungen des Mantelbodens geführten Madenschräubend bei jeder beliebigen Stellung der Mantelhaube gegenüber dem Fußstück in Eingriff mit dem Druckstück zur Herstellung der Verriegelung gelangen können. Bei dieser Ausbildung des Druckstückes werden nur ein bis zwei Schrauben benütigt: Außerdem ist im Mantelboden noch hinreichend Platz zur Anbringung eines Schlitzes t zum Ansetzen des Schraubenziehers vorhanden.The one screwed onto the base / and designed as a union nut Mantelhaubea can be rotated with the plate-shaped pressure piece c by means of a rivet bolt b tied together. According to the invention, the one located directly under the casing floor is now Part of the pressure piece c designed as a disk s; so that the two in tapped holes the bottom of the mantle guided grub screw in any position of the mantle hood opposite the foot piece in engagement with the pressure piece to produce the lock can get. With this design of the pressure piece, only one or two Screws required: In addition, there is still enough space in the bottom of the jacket for attachment a slot t is available for inserting the screwdriver.
