Description
Gehäuse"für einen elektrischen Temperaturfühler mit Anschlußleitungen -„,.".,-„ Housing "for an electrical temperature sensor with connecting lines -" ,. "., -"
Die Erfindung betrifft ein Gehäuse für einen elektrischen Temperaturfühler mit Anschlußleitungen, insbesondere in Verbindung mit der Drehzahlregelung von Ventilatoren, welches zwischen Befestigungsort und Temperaturfühlort isolierend ausgebildet ist.The invention relates to a housing for an electrical temperature sensor with connecting lines, in particular in Connection with the speed control of fans, which is located between the mounting location and the temperature sensor location is designed to be insulating.
Bei derartigen Geräten ist es erforderlich, Temperaturen in Luft oder anderen gasförmigen oder flüssigen Medien zu erfassen. Dabei wird meist der eigentliche Temperaturfühler von einem. Gehäuse umgeben sein. Das Gehäuse soll meist ausreichende Isolierstrecken gegen netzspannimgsfuhrende Fühler-Bauelemente aufweisen, aber auch sicherstellen, daß am Fühlerort die Umgebungstemperatur angenommen wird und keine nennenswerte Abhängigkeit von einem allfällig anders temperierten Montageort des Fühlergehäuses besteht.With such devices it is necessary to set temperatures in air or other gaseous or liquid media capture. The actual temperature sensor is usually used by one. Housing to be surrounded. The housing should usually be sufficient Isolation distances against mains voltage-carrying sensor components but also ensure that the ambient temperature is assumed at the sensor location and not at all there is a significant dependence on a possibly different temperature installation location of the sensor housing.
Es sind Ausführungen von Fühlergehäusen bekannt, bei denen ein metallischer Fühlerkopf mit guter Wärmeleistung mittels einer thermischen Isolierstrecke an einem Temperaturregelgerät befestigt wird. In diesem Fühlerkopf wird dann die nötige Isolierstrecke untergebracht.There are known designs of sensor housings in which a metallic sensor head with good heat output by means of a thermal insulating distance is attached to a temperature control device. The necessary insulating distance housed.
Dabei ist es meist nötig, eine Vielzahl von Einzelelementen zu einem Temperaturfühler zusammenzufügen und Fühlergehäuse in schutzisolierter Ausführung nehmen sehr große DimensionenIt is usually necessary to combine a large number of individual elements to form a temperature sensor and sensor housing in double-insulated design take up very large dimensions

Der Erfindung liegt die Aufgabe zugrunde, eine möglichst vollisolierte Ausführung eines Temperaturfühlers zu schaffen, vielohe auch an Gehäusen mit einer gewissen Übertemperatur montiert werden kann.The invention is based on the object of creating a temperature sensor that is as fully insulated as possible and can perhaps also be mounted on housings with a certain excess temperature.
Dieee Aufgabe wird erfindungsgemäß dadurch gelöst, daß das gesamte Gehäuse aus elektrisch nicht leitendem Isoliermaterial besteht, das zumindest im Bereich des Temperaturfühlortes eine rippen- oder wellenartig vergrößerte Oberfläche aufweist. 'The object is achieved according to the invention in that the entire housing consists of electrically non-conductive insulating material, at least in the area of the temperature sensor location has a rib-like or wave-like enlarged surface. '
In vorteilhafter Weise ist die Gehäuseoberfläche zwischen Befestigungsort und Temperaturfühlort rippen- und/oder stegärtig ausgebildet. Ferner kann es von Vorteil sein, die Oberfläche längs der gesamten Gehäuselänge querrippenförmig auszubilden.Advantageously, the housing surface is rib-like and / or web-like between the fastening location and the temperature sensing location educated. Furthermore, it can be advantageous for the surface to be in the form of transverse ribs along the entire length of the housing to train.
Ein Ausführungsbeispiel zeigt Mg. 1. Vom Montageort 1 führt ein dünner Steg 2 zu Rippen 3 in. der Umgebung des Fühlerortes 4· Der Zuführungskanal 5 für die elektrischen Anschlußdrähte wird mit einem wärmedämmenden elastischen Material verstopft.Mg. 1 shows an exemplary embodiment a thin web 2 to ribs 3 in. the vicinity of the sensor location 4 · The feed channel 5 for the electrical Connecting wires is made with a heat insulating elastic Material clogged.
Pig. 2 zeigt dieselbe Anordnung mit entlang des Fühlergehäuses gleichmäßig angeordneten Rippen.Pig. 2 shows the same arrangement with ribs evenly arranged along the sensor housing.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin,daß ein vollisolierter Fühler gebildet wird, welcher in einem Arbeitsgang, eventuell auch durch Umspritzen des Fühlers hergestellt werden kann.The advantages achieved with the invention are in particular that a fully insulated sensor is formed, which can be produced in one operation, possibly also by overmoulding the sensor.
