Definitions

the present invention relates to a temperature monitor with a bimetallic switching mechanism that protects a consumer in the event of overtemperature.
Such temperature monitors are used to protect electrical consumers, for which purpose they are connected in series with the consumer, so that its operating current through the Temperature monitor flows.
the temperature monitor is in close thermal contact with the consumer to be monitored, so that it transmits its temperature to the bimetal switchgear. If the temperature of the consumer rises inadmissibly, the bimetallic switching mechanism opens and the current flow to the consumer is interrupted.
Such a temperature monitor is known from DE-OS-41 42 716.
the known temperature monitor comprises a bimetallic switching mechanism which opens in the event of overtemperature or overcurrent, to which a first heating resistor is connected in parallel and with which a second heating resistor is connected in series.
a further temperature monitor known from DE-OS-43 36 564 comprises a ceramic carrier plate provided with conductive and insulating coatings, on which an encapsulated bimetal switching mechanism is arranged, next to which a PTC thermistor module is seated, which is electrically connected in parallel with the bimetal switching mechanism and acts as the first heating resistor.
a thick-film resistor is also arranged on the ceramic carrier plate, which leads under the bimetal switchgear and is connected in series with it. However, the series resistor is not used to protect overcurrent, but to set the switching point.
the task of these known temperature monitors is to interrupt the flow of current through the electrical consumer when this consumer has an excessively high temperature, or possibly also when the current through the consumer has excessively high values.
the known temperature monitor is connected in series to the consumer, so that the temperature monitor is traversed by the current flowing through the consumer, the bimetal switchgear being closed at temperatures below the response temperature and / or at currents below the response current.
the operating current of the consumer flows through the series connected second heating resistor of a few ohms as well as through the closed contacts of the bimetallic switching mechanism that bridges the first heating resistor. If the temperature of the consumer now exceeds a predetermined limit value, the bimetallic switching mechanism that is in thermal contact with the consumer suddenly opens its contacts by a bimetallic snap disk snapping around inside the bimetallic switching mechanism. The current now flows through the heating resistor connected in series and via the second heating resistor, which has such a large resistance that the current is very much lower than the original operating current, so that the consumer is virtually switched off.
temperature monitor known from DE-OS-43 36 564 satisfies many functional requirements, it is disadvantageous that it has a relatively bulky and large construction, which is due in particular to the ceramic carrier plate.
temperature monitors of this type are usually made very small, for example they have a diameter of 10 mm and a height of 5 mm, which places extreme demands on the manufacturing accuracy and at the same time the need for simple, yet functionally reliable constructions justified.
a temperature monitor with self-holding is known by means of a heating resistor connected in parallel and a heating resistor integrated in a small space and connected in series, which ensures current monitoring.
the series resistor is arranged as an etched or stamped part or as a film printed with a resistor in the immediate vicinity and in thermal and electrical contact with the spring washer of the bimetal switching mechanism in such a way that it comes to rest in the bottom part of the housing.
the etched or stamped parts used here as heating resistors cannot be manufactured too precisely with regard to the resistance value and only for a small resistance range.
a temperature monitor constructed according to the modular principle with a bimetal switching mechanism which switches to protect a consumer in the event of overtemperature, and which is assigned to the bimetal switching mechanism first electrical component, which at least when the bimetal switchgear is open, lies in series between connections of the temperature monitor, and a second electrical component assigned to the bimetal switchgear, which, at least when the bimetal switchgear is closed, lies in series with the latter between the connections of the temperature monitor, the First component with a comparable mechanical structure as a heating resistor or as an insulator and / or the second component with a comparable mechanical structure is designed as a series resistor or as a short-circuit part, so that with the same mechanical structure, temperature monitors with pure overtemperature protection, with overtemperature protection and self-holding function, with overtemperature protection and current sensitivity or be provided with overtemperature protection, self-holding function and current sensitivity.
the object underlying the invention is completely achieved in this way.
the inventors have found that it is surprisingly possible, with a corresponding arrangement of the individual parts, to design them either as a resistance element or as a short-circuit part / insulator, so that two alternatives must be kept available for the components in question in order to assemble a total of four different temperature monitors to be able to.
the storage of various parts known from the prior art is thus avoided.
a housing accommodating the bimetallic switching mechanism which has a pot-like, electrically conductive lower part and an electrically conductive cover part which closes the latter and is connected to the lower part via insulation, the first component being between the cover part and the lower part is connected, the second component is arranged under the bimetallic switching mechanism at the bottom of the lower part, which is between the lower part and a contact surface is switched, and the bimetallic switching mechanism in the closed state connects the cover part to the contact surface.
the second component is a plate covering the bottom of the lower part, which is connected between the contact surface and the lower part, the plate either having 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 represents a short circuit between the contact surface and the lower part.
the contact surface is preferably formed on an electrically conductive ring which is arranged between the plate and the bimetallic switching mechanism.
the first component is a ring part on which the cover part rests and through the ring opening of which the bimetallic switching mechanism comes into contact with the cover part, the ring part preferably resting on an electrically conductive ring disk which is conductive with the Lower part is connected.
the ring part is either made of resistance material, preferably PTC material, or an insulator.
the bimetallic switching mechanism comprises a fixed switching contact carried by the cover part and an associated movable switching contact, which is carried by a spring washer which is movable by a bimetallic snap disk and is electrically connected to the latter, the spring washer preferably located on the contact surface supports and presses the movable switch contact against the fixed switch contact when the bimetal switchgear is in its closed state.
the advantage here is that first electrical insulation is achieved between the lower part on the one hand and the plate, the spring washer and the bimetallic snap disc on the other hand, this insulation also serving as a support for the electrically conductive washer, via which the ring part with the lower part in Connection came.
a temperature monitor which comprises a housing 12 which has a lower part 13 made of electrically conductive material and a cover part 14 also made of electrically conductive material, by means of which the lower part 13 is closed.
an insulating sleeve 15 is provided between the lower part 13 and the cover part 14, which overlaps the cover part 14 laterally and partially above.
An edge 16 of the lower part 13 projects over the insulating sleeve 15 and is crimped over in order to close the housing 12.
the cover part 14 is supported with its underside on a first electrical component 17 which is designed as a ring part 18.
the ring part 18 in turn rests on an electrically conductive ring disk 19 which is conductively connected to the lower part 13 at its edges.
the ring disk 19 is provided on its underside, which points away from the ring part 18, with an insulating layer 20, by means of which it rests on a tubular insulating part 21.
the insulating part 21 in turn is supported by a shoulder 22 on an electrically conductive ring 23, on the upper side of which a contact surface 24 is provided.
the ring 23 in turn rests on a second electrical component 25 in the form of a plate 26 which is arranged in the lower part 13 at the bottom 27 thereof.
the plate 26 has a plated-through hole 28, which establishes a conductive connection between the lower part 13 and the upper side 29 of the plate 26.
a bimetallic snap disk 34 is placed over the movable switching contact 32 and, in the switching state shown in FIG. 1, has a temperature below its switching temperature.
a strand 38 is provided on the cover part 14 as the first connection 37, while a further strand 40 is welded onto the edge 16 of the lower part 13 as a second connection 39.
the first electrical component 17 is connected between the cover part 14 and the lower part 13, a series circuit comprising the bimetallic switching mechanism 35 and the second electrical component 25 being arranged in parallel with this first electrical component, as is shown in the electrical equivalent circuit diagram 2 is indicated.
the temperature monitor 10 described so far is based on the modular principle in that both the first electrical component 17 and the second electrical component 25 can be constructed on the one hand as heating resistors, but on the other hand as an insulator / short-circuit part.
the ring part 18 can for example be an insulating part 41 or a PTC resistor 42.
the plate 26 can either be an electrical short-circuit part 43 or else a carrier part 44 on which an electrical series resistor R V is arranged.
This series resistor R V can, for example, run as a thick-film resistor on the upper side 29 and can be connected between the electrically conductive ring 23 and the plated-through hole 28.
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.
the component 17 is designed as a holding resistor R H , the current flowing through this component 17 when the bimetal switch mechanism 35 is open ensures that sufficient heat is generated to keep the bimetal switch mechanism 35 open.
the resistance of the series circuit comprising the bimetallic switching mechanism 35 and the component 25 is very much lower than the resistance of the component 17, so that virtually no current flows through this component 17.
