Description
- Fig. 1
- einen neuen Temperaturwächter in einer geschnittenen Seitenansicht, bei dem an der Isolierfolie ein aus Übersichtlichkeitsgründen nicht dargestellter Heizwiderstand ausgebildet ist;
- Fig. 2
- eine für den Einbau in den Temperaturwächter aus Fig. 1 geeignete Isolierfolie, vor dem Einbau, vergrößert und nicht maßstabsgerecht;
- Fig. 3
- in einer Darstellung wie Fig. 2 ein weiteres Ausführungsbeispiel der mit einem Heizwiderstand versehenen Isolierfolie;
- Fig. 4
- eine Draufsicht auf die Isolierfolie aus Fig. 3.
Claims (10)
- Temperaturwächter mit einem bei Übertemperatur schaltenden Bimetall-Schaltwerk (15) und einem damit verschalteten Heizwiderstand (23), der im Sinne einer Selbsthaltefunktion wirkt und an einer Folie (22, 24) ausgebildet ist, die zur elektrischen Isolation vorgesehen ist, dadurch gekennzeichnet, daß ein das Schaltwerk (15) aufnehmendes Gehäuseunterteil (11) aus leitfähigem Material sowie ein das Gehäuseunterteil (11) verschließendes Deckelteil (12) aus leitfähigem Material vorgesehen ist, und daß die Folie (22, 24) für eine erforderliche Isolation zwischen Gehäuseunterteil (11) und Deckelteil (12) sorgt.
- Temperaturwächter nach Anspruch 1, dadurch gekennzeichnet, daß das Gehäuseunterteil (11) und/oder das Deckelteil (12) aus Metall gefertigt sind.
- Temperaturwächter nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Folie (22, 24) ein- oder beidseitig mit Widerstandsmaterial (25, 27, 29; 34, 36) versehen, vorzugsweise mit Widerstandsbahnen (34, 36) beschichtet oder bedruckt ist.
- Temperaturwächter nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß die Folie (22, 24) ein Widerstandsmaterial (25) aus Kaltleitermaterial aufweist.
- Temperaturwächter nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß die Folie (22, 24) zumindest an einer Stelle (32) durchkontaktiert ist, so daß Widerstandsmaterial (27, 29; 34, 36) auf beiden Seiten (33, 35) der Folie (22, 24) elektrisch miteinander verbunden ist.
- Temperaturwächter nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß die Folie (22, 24) eine Heizfolie (37) ist, die eine isolierende Kunststoffolie (24) mit als Heizwiderstand (23) dienenden Leiterbahnen (34, 36) aufweist.
- Temperaturwächter nach einem der Ansprüche 1 bis 6, dadurch gekennzeichnet, daß die Folie (22, 24) eine Kaltleiterfolie, vorzugsweise eine PTC-Folie ist.
- Temperaturwächter nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, daß die Folie (22, 24) bereichsweise mit Widerstandsmaterial (25) versehen ist.
- Temperaturwächter nach einem der Ansprüche 1 bis 8, dadurch gekennzeichnet, daß die Folie (22, 24) einseitig mit Widerstandsmaterial (25) versehen ist und auf der anderen Seite der Kontaktierung dienende Leiterbahnen (34, 36) aufweist.
- Temperaturwächter nach einem der Ansprüche 1 bis 9, dadurch gekennzeichnet, daß die Folie (22, 24) ggf. unter Zwischenlage von weiterem Isoliermaterial zwischen Gehäuseunterteil (11) und Deckelteil (12) eingeklemmt wird.
