Description

Verfahren zur Herstellung von Widerständen für Heizgeräte u. dgl., insbesondere solchen, die Erschütterungen ausgesetzt werden Ein Verfahren zum Isolieren von elektrischen Heiz- und Kochgeräten, bei dem ein begrenzt langer Widerstand in Glaswolle eingehüllt und letztere nach außen hin durch eine feste Glasschicht abgeschlossen wird, ist bekannt. Diesem Verfahren gegenüber befaßt sich das Verfahren gemäß der Erfindung zwar ebenfalls mit der Herstellung von begrenzt langen Widerständen für Heizgeräte u. dgl., und zwar insbesondere solchen, die Erschütterungen ausgesetzt sind, z.B. bei Fahrzeugen. Jedoch führt bei demn erfindungsgemäßen Verfahren die eigenartige Rettung in ein festes Widerstandsgehäuse eine feste Bindung der Leiter mit der isolierenden Glaswolle in der Weise herbei, daß ein nachgidbiges (elastisches) Gebilde entsteht, welches selbst starken Erschütterungen nit Erfolg Widerstand bietet. Dieses neue Verfahren kennzeichnet sich dadurch, daß die Widerstandsleiter in eine dicke Lage Glaswolle eingebettet und dann auf eine solche Temperatur und Dauer zum Erhitzen gebracht werden, daß die Leiter in der sie umgebenden Glaswolle festgelegt werden.Process for the production of resistors for heating devices and the like, especially those exposed to vibrations A method of isolation of electrical heating and cooking appliances with a limited resistance in Glass wool encased and the latter closed off from the outside by a solid glass layer is known. In relation to this procedure, the procedure is dealt with in accordance with Invention, although also with the production of resistors of limited length for Heaters and the like, especially those exposed to vibrations e.g. in vehicles. However, leads in the inventive method strange rescue in a solid resistance housing a solid binding of the ladder with the insulating glass wool in such a way that a flexible (elastic) A structure emerges which successfully offers resistance even to strong vibrations. This new method is characterized in that the resistance ladder in a thick layer of glass wool embedded and then to such a temperature and duration for Heating are brought about that the conductors are set in the glass wool surrounding them will.

Das Verfahren besteht in folgendem: Nach dem Einbetten der Widerstandsleiter in die dicke, auf ein festes Widerstandsgehäuse gebrachte Glaswolle wird diese in geeigneter Weise beschwert und dann einer Erhitzung ausgesetzt. Die Erhitzungstemperatur. <lie beträchtlich unter der Schnielzternperatur der Glaswolle und ebenso beträchtlich über der Betriebstemperatur des Heizgerätes liegt, beträgt etwa bis zu 6oo bis 700° C; die Erhitzungddauer, ilie ntir Sekunden beträgt, richtet sich .nach *,der besonderen Eigenschaft @er zur Anwendung belangenden Glastwolle. Es erfolgt dadurch ein Festlegen der Leiter nl der sie umgehenden Glaswolle.The procedure consists of the following: After embedding the resistor ladder into the thick glass wool placed on a solid resistor housing, it is turned into suitably weighted and then subjected to heating. The heating temperature. <was considerably below the Schnielztern temperature of the glass wool and just as considerably is above the operating temperature of the heater is about up to 600 to 700 ° C; the heating time, which is ntir seconds, depends on *, the special one characteristic @er for the application relevant glass wool. It takes place thereby fixing the conductors to the glass wool bypassing them.

Nach demn Verfahren hergestellte Widertiiänlde eignen sich deslhalbl hesonders für .,C.jL .ii1@'z# vrit1%' ,.. @en atsgesetzt sind, weil die Widerstände ein n ein festes Widerstandsgehiiuse eingehettees, nachgiebiges (elastisches) Gebilde Bartellen. dlas auftretenden Erschütterungen weiestgehend standhält.Countries produced according to the process are therefore particularly suitable for ., C.jL .ii1 @ 'z # vrit1%' , .. @ are set because the resistances are a resilient (elastic) structure embedded in a solid resistance housing. which can withstand any vibrations as much as possible.
