Abstract
Description
Die Erfindung betrifft einen Elektroanschluß für Heizelemente in Strahlungsheizkörpern, insbesondere für Glaskeramikkochflächen.The invention relates to an electrical connection for heating elements in radiant heaters, especially for glass ceramic cooktops.
Die DE 23 39 768 beschreibt einen Elektroanschluß für eine Heizwendel, bei der die Heizwendel bildende Draht im Anschlußbereich verdrillt ist und durch den Boden des Strahlungsheizkörpers herausgeführt wird. Erheblicher Aufwand bei der Herstellung des verdrillten Anschlußstückes sowie bei der Leitungsdurchführung sind Nachteile dieser Lösung.DE 23 39 768 describes an electrical connection for a heating coil in which the heating coil forming wire is twisted in the connection area and through the bottom of the radiant heater is brought out. Considerable effort in the manufacture of the twisted connector as well Disadvantages of this solution are when routing cables.
Aus der DE 35 39 881 ist ein Elektroanschluß zu entnehmen, bei welchem sich am Ende der Heizwendel ein Anschlußstift befindet, der mit einem u-förmig gestaltetem Endstück im Isolierkörper verankert ist. Sein freier Schenkel ragt nach oben über den Isolierkörper hinaus, so daß hier der Anschluß der Betriebsspannung erfolgen kann. Der Anschlußstift muß während der Herstellung des Isolierkörpers in diesen eingebracht werden. Da die Isolierkörper aus mikroporösem Wärmedämmstoff aber in der Regel als Fertigteile bezogen werden, ist diese Lösung nur mit zusätzlichen Erschwernissen zu realisieren.From DE 35 39 881 an electrical connection can be seen, in which at the end of the Heating coil is a connector pin with a U-shaped end piece in the insulating body is anchored. Its free leg protrudes upwards beyond the insulating body, so that here the Connection of the operating voltage can take place. The connector pin must be during the manufacture of the Insulator are introduced into this. Because the insulating body is made of microporous Thermal insulation material but usually purchased as finished parts, this solution is only with to realize additional difficulties.
Die Aufgabenstellung der Erfindung besteht in der konstruktiven Gestaltung eines Elektroanschlusses für Heizelemente, der während der Endmontage des Strahlungsheizkörpers zu realisieren ist, ohne daß Halterungselemente bereits während der Herstellung des Isolierkörpers in diesen eingebracht werden müssen.The object of the invention is the constructive design of a Electrical connection for heating elements, which during the final assembly of the radiant heater too is to be realized without mounting elements already during the manufacture of the insulating body these have to be introduced.
Erfindungsgemäß wird diese Aufgabenstellung dadurch gelöst, daß ein Anschlußwinkel vorgeschlagen wird, dessen einer Schenkel sowohl mit dem Endstück des Heizelementes als auch mit der Anschlußleitung verbunden ist, während der andere Schenkel des Anschlußwinkels in zweckmäßiger Weise im Isolierkörper fixiert ist.According to the invention, this task is solved in that a connection angle is proposed, one leg with both the end piece of the heating element and with the connecting line is connected, while the other leg of the connecting angle in is expediently fixed in the insulating body.
Die Erfindung soll nachfolgend anhand eines Ausführungsbeispieles näher erläutert werden. In den zugehörigen Zeichnungen zeigen:The invention will be explained in more detail below using an exemplary embodiment. In the associated drawings show:
Fig. 1 die Draufsicht auf einen Teil des Strahlungsheizkörpers mit Darstellung des Anschlußbereiches der Heizwendeln, Fig. 1 is a plan view of a portion of the radiant heater with illustration of the connection region of the heating coils,
Fig. 2 bis 5 verschiedene Ausführungsformen des Anschlußwinkels. Fig. 2 to 5 different embodiments of the connection angle.
Auf dem Isolierkörper 1 aus mikroporösem Wärmedämmstoff sind die Heizwendeln 2 angeordnet, welche mit ihren Enden an die Betriebsspannung angeschlossen sind. Zu diesem Zweck sind die Anschlußwinkel 3 aus CrNi-Draht vorgesehen. Der eine Schenkel des Anschlußwinkels 3 ragt in den Endbereich der Heizwendel 2 hinein und ist mit deren letzten Windungen durch Schweißen verbunden. An dem selben Schenkel ist auch die Anschlußleitung 4 zur Zuführung der Betriebsspannung mittels einer Schweißstelle angeschlossen. Diese Anschlußleitung 4 wird seitlich durch den Isolierkörper nach außen geführt.On the insulating body 1 made of microporous thermal insulation, the heating coils 2 are arranged, which are connected at their ends to the operating voltage. For this purpose, the connection bracket 3 made of CrNi wire is provided. One leg of the connection bracket 3 protrudes into the end region of the heating coil 2 and is connected to its last turns by welding. The connecting line 4 for supplying the operating voltage is connected to the same leg by means of a welding point. This connecting line 4 is guided laterally through the insulating body to the outside.
Der andere Schenkel des Anschlußwinkels 3 wird in den Isolierkörper 1 eingesteckt. In den Fig. 2 bis 5 sind verschiedene Ausführungsformen dieses zweiten Schenkels dargestellt. Nach Fig. 2 ist das Schenkelende kegelförmig ausgeführt, während Fig. 3 eine keilförmige Spitze zeigt. Eine mit Widerhaken versehene Schenkelspitze ist in Fig. 4 dargestellt. Der Fig. 5 entsprechend ist der Winkel zwischen den beiden Schenkeln des Anschlußwinkels 3 kleiner als 90 Grad. Die Ausführung nach Fig. 5 ist mit den vorher beschriebenen Ausführungsformen kombinierbar.The other leg of the connection bracket 3 is inserted into the insulating body 1 . In Figs. 2 to 5 different embodiments are shown of this second leg. According to Fig. 2, the leg end is conical, while Fig. 3 shows a wedge-shaped tip. A barbed thigh tip is shown in FIG. 4. Corresponding to FIG. 5, the angle between the two legs of the connecting angle 3 is less than 90 degrees. The embodiment of FIG. 5 can be combined with the previously described embodiments.
