Abstract

Die Erfindung betrifft eine elektrische Drahtwicklung, insbesondere Heizdrahtwicklung, bei der der Draht zu einer Spiralfederform um einen Trägerkörper gewickelt ist. Der Trägerkörper weist daran angepaßte Nuten auf, in die die einzelnen Windungen eingreifen. Der Trägerkörper (43; 50) aus Isolierstoff ist zweigeteilt und zwischen den Teilen (20, 21; 51, 52) ist eine diese auseinanderdrückende Federanordnung (22, 55) eingesetzt.

The invention relates to an electrical wire winding, in particular heating wire winding, in which the wire is wound into a coil spring shape around a carrier body. The carrier body has grooves adapted to it, into which the individual turns engage. The carrier body (43; 50) made of insulating material is divided into two and between the parts (20, 21; 51, 52) is inserted a spring arrangement (22, 55) that pushes them apart.
