Description

Elektrischer Heizkörper für Heißluftgebläse Es sind elektrische Heizkörper für Heißluftgebläse bekannt, die aus vier Blechwinkeln mit dazwischenliegenden Glimmerstreifen bestehen. Hierbei sind die Blechwinkel entweder elektrisch leitend miteinander verbunden, so daß sie nicht als getrennte Stromleiter verwendet werden können, oder es sind j e zwei Winkel stromleitend miteinander verbunden und diese Winkelpaare durch zwei lose zwischen ihnen liegende Glimmerstrei.-fen voneinander isoliert. Hierbei besteht diie Gefahr, daß diese Glimmerstreifen sich beim Stoßen und Fallen des Luftschlauches, in den der Heizkörper eingebaut ist, vercs,chieben: und den Glühdraht zerreißen.Electric heater for hot air guns They are electric heaters known for hot air blowers, which consist of four sheet metal angles with mica strips in between exist. The sheet metal angles are either connected to one another in an electrically conductive manner, so that they cannot, or are, used as separate conductors j e two angles are electrically connected to each other and these angle pairs by two mica strips lying loosely between them isolated from one another. Here is the danger that these mica streaks will collapse when the air tube is hit and dropped, in which the radiator is installed, push, push: and tear the filament.

Dieser Übelstand wird durch die Erfindung dadurch beseitigt, daß je zwei innere Metallschienen durch Distanzrohre und zweiäußere Schienen durch Bolzen stromleitend derart miteainander verbunden sind, daß, alle zur Isolierung des inneren Schienenpaares gegen das äußere Schienenpaar dienenden Glimmerstreifen unverschiebbar mit den Schienen verbunden sind. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht, und zwar zeigt Abb. i eine Längsansicht, zur Hälfte im Längsschnitt, und Abb. 2 einen Querschnitt.This drawback is eliminated by the invention that ever two inner metal rails through spacer tubes and two outer rails through bolts are electrically connected to each other in such a way that, all for the insulation of the inner Pair of rails against the outer pair of rails serving mica strips immovable connected to the rails. An embodiment of the invention is in Drawing illustrates, namely Fig. I shows a longitudinal view, half in Longitudinal section, and Fig. 2 is a cross section.

Zwei innere Schienen a und rcl sind durch Röhrchen b verbunden. Durch diese Röhrchen sind Bolzen e isoliert hindurchgeführt, welche die äußeren Schienen c und cl leitend miteinander verbinden. Zwischen jeeiner inneren, a, und einer äußeren Metallschiene c bzw. al und el liegen Glimmerstreifen d und dl, welche die Schienen gegeneinander isolieren, aber trotzdem mit diesen unverschiebbar verbunden sind. Die Glimmerstreifen sind breiter als die Metallschienen und dienen zur Aufnahme der Heizwicklung. Das eine Ende der Wicklung ist mit der inneren Schiene a durch eine Schraube/ verbunden, das andere Ende mit der äußeren Schiene cl durch die Mutter g des Bolzens e. Es sind somit die innere Schiene a. und die ,äußere Schiene cl die Stromleiter, welche zur Verbindung mit den Kontakten je einen zylindrischen Stift h und hl erhalten.Two inner rails a and rcl are connected by tube b. By These tubes are insulated through bolts e, which are the outer rails Connect c and cl conductively to one another. Between an inner, a, and an outer Metal rail c or al and el lie mica strips d and dl, which form the rails isolate against each other, but are still connected to them in such a way that they cannot be moved. The mica strips are wider than the metal rails and are used to accommodate the heating coil. One end of the winding is through to the inner rail a one screw / connected, the other end to the outer rail cl by the nut g of the bolt e. There are thus the inner rail a. and the, outer rail cl the current conductors, which are each cylindrical for connection to the contacts Pen h and hl received.
