Description

Die an elektrischen Maschinen oder Apparaten mit Kühlrippen angebauten Klemmenkästen haben im allgemeinen in gleicher Weise wie die Klemmenkästen für Maschinen mit glatter Mantelfläche den Klemmenraum umgebende rechteckige oder runde Anbauflansche. Da die Anbauflansche der Maschinen entsprechend ausgebildet sind, müssen am Klemmenkastensitz die Kühlrippen unterbrochen werden, wodurch ein erheblicher Teil der wirksamen Kühlfläche verlorengeht.Those attached to electrical machines or devices with cooling fins Terminal boxes are generally the same as terminal boxes for machines Rectangular or round mounting flanges surrounding the terminal area with a smooth jacket surface. Since the mounting flanges of the machines are designed accordingly, the terminal box must be seated the cooling fins are interrupted, whereby a considerable part of the effective cooling surface get lost.

Durch die Erfindung werden diese Schwierigkeiten beseitigt. Erfindungsgemäß ist der Klemmenkasten für den Anbau an eine elektrische Maschine oder Apparat mit Kühlrippengehäuse mittels zweier beiderseitig des Klemmenraums' in Richtung der Gehäuserippen etwa über die Klemmenkastenbreite sich erstreckende Hohlflansche am Gehäuse befestigt, deren dem Gehäuse zugekehrte Wände zum Teil durchbrochen sind und so mit den in etwa gleicher Weise höhl ausgebildeten verstärkten Kühlrippen am Gehäuse Durchführungen für die Wicklungsanschlußkabel 'bilden.The invention overcomes these difficulties. According to the invention is the terminal box for attachment to an electrical machine or apparatus with Cooling rib housing by means of two on both sides of the terminal space 'in the direction of the Housing ribs about the width of the terminal box extending hollow flanges on Fastened housing, the walls of which facing the housing are partially perforated and so with the reinforced cooling ribs, which are hollow in roughly the same way Form feedthroughs for the winding connection cables on the housing.

Die Erfindung soll an Hand des in Fig. i und 2 dargestellten Ausführungsbeispiels näher erläutert werden Fig. i zeigt einen an ein Kühlrippengehäuse angebauten Klemmenkasten im Querschnitt, die Fig. 2 den Klemmenkasten in Vorderansicht ohne Deckel.The invention is based on the embodiment shown in FIGS are explained in more detail Fig. i shows a terminal box attached to a cooling fin housing in cross section, FIG. 2 shows the terminal box in a front view without a cover.

Der aus dem Unterteil i und dem Deckel 2 bestehende Klemmenkasten ist an dem mit Kühlrippen 3 ausgestatteten Gehäuse 4 einer nicht weiter dargestellten elektrischen Maschine mittels Schrauben 5 befestigt, und zwar an den verstärkten Kühlrippen 6 und 7. Der Klemmenkastenunterteil hat zu diesem Zweck zwei in Richtung dieser Kühlrippen verlaufende Hohlflansche 8 und 9, deren dem Gehäuse 4 zugekehrte Wände i o und i i Durchbrechungen 12 und 13 haben. Diese bilden mit den an diesen Stellen ebenfalls höhl ausgeführten verstärkten Kühlrippen 6 und 7 Durchführungen 14 und 15 für die zu den Klemmen 16 geführten Wicklungsanschlußkabel 17. Die Klemmen 16 sind an Isolierkörpern 18 angeordnet, die in Ausnehmungen i9 der Klemmenkastenwand 20, beispielsweise mittels eines Metallklebers befestigt sind. Die Anbauflächen der Hohlflansche 8 und 9 bilden, ebenso wie die Anbauflächen der verstärkten Kühlrippen 6 und 7, eine zur Maschinenachse konzentrische Zylinderfläche.The terminal box consisting of the lower part i and the cover 2 is on the housing 4 equipped with cooling fins 3 a not shown electric machine fastened by means of screws 5, namely to the reinforced Cooling fins 6 and 7. The lower part of the terminal box has two in the direction for this purpose these cooling fins extending hollow flanges 8 and 9, the housing 4 facing Walls i o and i i have openings 12 and 13. These form with the at these Also make hollow reinforced cooling fins 6 and 7 bushings 14 and 15 for the winding connection cables led to the terminals 16. The terminals 16 are arranged on insulating bodies 18, which are located in recesses i9 in the terminal box wall 20, are attached, for example by means of a metal adhesive. The acreage the hollow flanges 8 and 9, as well as the mounting surfaces of the reinforced cooling fins 6 and 7, a cylinder surface concentric to the machine axis.

Dadurch, daß der Klemmenkasten nur parallel zu den Kühlrippen des Gehäuses verlaufende Anbauflansche hat, die zugleich die Durchführungen für die Wicklungsanschlußkabel bilden, können die Kühlrippen auch am Klemmenkastensitz die gesamte Gehäuselänge ungehindert durchlaufen, so daß keine Verkleinerung der wirksamen Kühlfläche erforderlich ist.Because the terminal box is only parallel to the cooling fins of the Housing has extending mounting flanges, which are also the bushings for the Form winding connection cables, the cooling fins can also be used on the terminal box seat run through the entire length of the housing unhindered, so that no reduction in size of the effective Cooling surface is required.
