Description

Es ist bekannt, daß es vorteilhaft ist, einer Unterbrecliungsfunkenstrecke zur Unterdrückung der Funkenbildung einen Kondensator parallel zu schalten. Besonders für Thermoschalter bestehen demnach zahlreiche Ausführungsformen, bei denen dieser Kondensator teils im Anschlußapparat, teils in der Nähe des Thermoschalters, teils auch in der Anschlußschnur untergebracht ist.It is known that it is advantageous to use an interruption spark gap for suppression to connect a capacitor in parallel with spark formation. There are therefore numerous, especially for thermal switches Embodiments in which this capacitor is partly in the connection apparatus, partly in near the thermal switch, partly also in the connecting cord.

Nun drückt aber jeder Ohms ehe oder in-, duktive Widerstand in der Verbindung zwischen Kondensator und Funkenstrecke die Löschwirkung des Kondensators herab, was nur durch Vergrößerung des Kondensators wieder ausgeglichen werden kann. Die nachstehend beschriebene neue Ausführungsform vermeidet jede Verbindungsleitung zwischen Kondensator und Kontaktstellen und ergibt hierdurch die wirkungsvollste und billigste Ausführung, indem der Kondensator und der Thermoschalter zu einem einzigen Bauteil vereinigt sind.But now every ohms presses before or in, Ductive resistance in the connection between the capacitor and the spark gap reduces the quenching effect of the capacitor, which can only be compensated for by enlarging the capacitor. The below described new embodiment avoids any connection line between capacitor and contact points and results thereby the most effective and cheapest execution by the capacitor and the Thermal switches are combined into a single component.

Ein Ausführungsbeispiel zeigt die beiliegende Zeichnung. 1 und 2 sind zwei Bimetallstreifen, die so - angeordnet sind, daß sie sich bei Erwärmung voneinander entfernen. 3 ist eine Glimmerzwischenlage, die, als Dielektrikum dienend, die Bimetallstreifen zum Kondensator ergänzt. 4 und 5 sind isoliert durch das Ganze hindurchgeführte Niet- oder Schraubverbindungen. Die rückwärts verlängerten Bimetallstreifen tragen bei die Anschlußklemmen, und die entsprechend abgekröpften Verlängerungen nach vorn, 7, tragen je eine Kontaktstelle.The accompanying drawing shows an exemplary embodiment. 1 and 2 are two bimetal strips, which are so - arranged that they move away from each other when heated. 3 is a mica liner that, Serving as a dielectric, the bimetallic strips are added to the capacitor. 4 and 5 are insulated rivet or screw connections passed through the whole. The backwards extended bimetallic strips contribute to the terminals, and the corresponding cranked extensions to the front, 7, each have a contact point.

Die Ausbildung dieser Kontaktstellen wie auch der gegebenenfalls erforderliche Einbau des Schalters in ein passendes Gehäuse erfolgt in an sich bekannter Weise.The formation of these contact points as well as the installation that may be required of the switch in a suitable housing takes place in a manner known per se.

Patentanspruch:Claim: Thermostatischer Schalter mit Funkenlöschung durch Kondensator und mit zwei thermostatischen Gliedern, von denen jedes einen der zusammenarbeitenden Kontakte trägt, dadurch gekennzeichnet, daß diese thermostatischen Glieder, z. B. Bimetallstreifen, unter Zwischenfügung isolierender Zwischenlagen teilweise unmittelbar derart aufeinanderliegen, daß die aufeinanderliegenden Teile gleichzeitig die Kondensatorbelegungen bilden und somit der Thermostat und der Kondensator zu einem einzigen Bauteil vereinigt sind.Thermostatic switch with spark suppression by capacitor and with two thermostatic members, each of which is one of the cooperating contacts carries, characterized in that these thermostatic members, for. B. bimetal strips, with the interposition of insulating intermediate layers partly directly on top of one another in such a way that the parts lying on top of one another form the capacitor assignments at the same time and thus the thermostat and the condenser are combined into a single component.
