Definitions
- Such a temperature monitor is known from EP-A1-226 663.
- Such temperature monitors are used to protect electrical consumers used for which they are connected in series with the consumer be so that its operating current through the Temperature monitor flows.
- the temperature monitor is close thermal contact with the consumer to be monitored, so that this transfers its temperature to the bimetal switchgear. If the temperature of the consumer rises inadmissibly, so the bimetal switchgear opens, and the current flow to it Consumer is interrupted.
- Such a temperature monitor is from DE-OS-41 42 716 known.
- the known temperature monitor includes an overtemperature or overcurrent opening bimetal switchgear, to which a first Heating resistor in parallel and with a second heating resistor is connected in series.
- Another temperature monitor known from DE-OS-43 36 564 includes one with conductive and insulating coatings Provided ceramic carrier plate, on which an encapsulated bimetal rear derailleur is arranged, next to which a PTC thermistor module sits, which is electrically parallel to the bimetal rear derailleur is switched and acts as the first heating resistor.
- Ceramic carrier plate On the Ceramic carrier plate is also a thick film resistor arranged, which leads under the bimetal rear derailleur and with this is connected in series. The series resistor is used here however, not for overcurrent protection, but for adjustment of the switching point.
- the operating current of the consumer flows in series switched second heating resistor of a few ohms as well the closed contacts of the bimetallic rear derailleur that the bridges the first heating resistor.
- temperature monitor known from DE-OS-43 36 564 functionally meets many requirements, it is disadvantageous that it has a relatively bulky and large design, the is due in particular to the ceramic carrier plate. For reasons of accommodation and heat capacity Such temperature monitors are usually very small executed, for example. They have a diameter of 10 mm and a height of 5 mm, which places extreme demands on manufacturing accuracy represents and at the same time the need simple and at the same time functionally reliable constructions.
- this task with regard to the temperature monitor solved in that the first component at comparable mechanical construction as a heating resistor or as an insulator and / or the second component with a comparable mechanical Structure designed as a series resistor or as a short-circuit part is, so that with the same mechanical structure according to the modular principle built-up temperature monitor with pure overtemperature protection, with overtemperature protection and self-holding function, with overtemperature protection and current sensitivity or with Over-temperature protection, self-holding function and current sensitivity are provided, one being the bimetal rear derailleur Receiving housing is provided, which is a pot-like, electrical conductive lower part and a closing, has electrically conductive cover part, which with the lower part is connected via insulation, the first component between Cover part and lower part is switched, under the bimetal rear derailleur the second component is arranged at the bottom of the lower part is that between the lower part and a contact surface is switched, and the bimetal rear derailleur in the closed State the cover part connects to the contact surface.
- This measure is also from a design point of view an advantage, because it is made of an extremely pressure-resistant housing electrically conductive lower part and lid part formed that completely encapsulates the bimetal rear derailleur, so that this protected from external influences in a manner known per se becomes.
- Another advantage is that the assembly of the new Temperature monitor designed very simple, in the lower part you only have to do the second component one after the other, then the bimetal rear derailleur, then the first component and finally the cover part with the interposition of insulation be introduced, while still being inserted for the to ensure electrical connections between the individual parts is.
- the second component is a Bottom of the base covering plate is between the Contact surface and the lower part is switched, the plate either has an insulating carrier material on which a series resistor is arranged, which with the contact surface and is connected to the lower part, or even a short circuit represents between the contact surface and the lower part.
- the contact surface is preferably electrical conductive ring formed between the plate and the bimetal rear derailleur is arranged.
- the first component is a ring part is on which the cover part rests and through its ring opening through the bimetal rear derailleur in connection with the cover part arrives, the ring member preferably on an electrical conductive ring washer, which is conductive with the lower part connected is.
- the ring part is either made of resistance material, preferably made of PTC material, or else an isolator.
- the advantage here is that there is first electrical insulation between the lower part on the one hand and the plate on the other, the spring washer and the bimetallic snap washer is, this isolation at the same time as a support for the serves as an electrically conductive washer over which the ring part comes into contact with the lower part.
- the cover part 14 is supported with its underside a first electrical component 17, which is in the form of a ring part 18 is trained.
- the ring part 18 in turn lies on one electrically conductive washer 19 on its edges is conductively connected to the lower part 13.
- the ring 23 in turn lies on a second electrical component 25 in the form of a plate 26 which in the lower part 13 on the Floor 27 is arranged.
- the plate 26 has a via 28 on that a conductive connection between the Lower part 13 and the top 29 of the plate 26 produces.
- a convex spring washer 31 sits on the contact surface 24, which carries a movable switch contact 32, which by the Ring part 18 cooperates with a fixed switching contact 33, which is arranged on the cover part 14.
- On the movable switch contact 32 is a bimetallic snap disk 34 put over, in the switching state shown in Fig. 1 Has temperature below their switching temperature.
- Bimetal switching mechanism 35 which in the state shown in FIG. 1 an electrically conductive connection between the cover part 14 and the contact surface 24. If the temperature the bimetallic snap disk 34 beyond the switching temperature increases, the bimetallic snap disc suddenly snaps off of the convex shown into a concave shape, whereupon they now with its outer edge on the insulating layer 20 supports and the movable switch contact against the force of Spring washer 31 lifts off the fixed switch contact 33, so that the electrical connection just discussed between the Cover part 14 and the contact surface 24 is opened.
- temperature monitors 10 which are completely identical in terms of their mechanical properties, but which differ in their electrical properties, can thus be produced in a modular manner. If, for example, the component 17 is an insulating part 41 and the component 25 is a short-circuit part 43, the temperature monitor 10 fulfills a pure temperature monitoring function. If, on the other hand, the component 25 is equipped with a series resistor R V , the temperature monitor is current sensitive, the flowing current generates heat in the series resistor R V , which ensures that the bimetallic switching mechanism 35 opens when the current flow is too high.
