Definitions

  • the invention relates to a device for temperature and / or current-dependent switching of an electrical connection, such as temperature controllers, monitors or the like.
  • a device for temperature and / or current-dependent switching of an electrical connection such as temperature controllers, monitors or the like.
  • the movable contact and Mating contact are provided with connecting elements for connecting supply lines and are connected to connecting elements which are kept at a distance by a common insulating insulating part.
  • a device is shown in US-A-3 067 306.
  • the bimetal element carrying the movable contact pushes ever further against the contact and can cause irreversible changes, especially subject to deformations that change pure switching temperatures beyond specified tolerances.
  • the invention is therefore based on the object of providing such a device which is easy to manufacture in terms of production technology and in which a change in switching temperature is reliably avoided.
  • the above-mentioned object is achieved in a device according to the upper handle in that the counter-contact is elastically resiliently mounted on the supporting part.
  • the device can be designed either as a make contact or as a break contact; the connection between the contact and the mating contact can therefore be released if the temperature is too high, i.e. is above a predetermined switching temperature, for example in the case of a motor or the like for interrupting operation or as a controller in a heating device, while it is below the switching temperature Temperature closes; However, it can also be provided that the connection opens at a temperature below the switching temperature and closes at a temperature above the switching temperature, for example in the case of a cooling device, etc.
  • the bimetallic element can in principle itself be electrically conductive and, if appropriate, also as current-sensitive Switches act, ie switch their switching process not on the basis of any ambient temperature, but on the basis of the heat directly generated in it by the current flow itself; in this case, of course, it opens when the heat is excessively generated, since this is only generated in the closed state.
  • configurations are also possible in which the bimetal element is current-free and the current is conducted via other elements for movable contact, as is known in principle in a wide variety of ways.
  • the support member is annular and on the one hand carries an essentially circular bimetallic element on its periphery which switches the movable contact and on the other hand defines an elastic disk spring which carries the counter-contact on its periphery.
  • the mating contact is arranged at one end of an elongated elastic tongue, a mating contact also being mounted on the supporting part; that the mounting of the counter-contact tongue takes place in that it is fixed to the support part with the section, and in that the bimetallic element is also designed to be stretched, carries the movable contact at one end and is fixed to the support part with a non-contact area.
  • the mating contact tongue is formed in one piece with its connecting element, and that the bimetallic element is connected to a conductive part, which is fixed on the one hand by friction on the supporting part and on the other hand forms a connecting element for the movable contact in one piece and / or that on Support part approaches are formed with undercuts, and that the connecting piece connected to the bimetallic element has edges which are bent out of its plane, and in this way the undercuts are introduced between the approaches and a central section of the supporting part which, under clamping action, the edges on the approaches and the actual connecting piece at the central section of the supporting part abuts, and that edges corresponding to the edges are also formed on the counter-contact tongue in the region of a section, that the section is inserted with its edges in the undercuts corresponding to undercuts.
  • the switch has considerable manufacturing advantages.
  • the contact unit formed from the contact, the bimetallic element, the connecting piece connected to it and the connecting piece formed integrally with this, and the counter-contact unit formed from the mating contact and the counter-contact tongue and the connecting element formed integrally with this, are simply pressed into the prefabricated supporting part to produce the switch, whereby the connection elements are each pushed through areas kept clear between the respective two approaches.
  • the switch manufactured in this way can then be used directly at its work station.
  • the connection elements can be bent in a corresponding manner before attachment to the support part or afterwards, the latter being For example, it makes sense if an end plate is formed on the support part, around the edge of which the connecting elements are then preferably guided around.
  • the assembly described can be done fully automatically.
  • a front end of the supporting part which may be designed as an end plate, forms the end, while the other housing is designed in the form of a pocket.
  • the connection elements are led out between the front plate and the housing and sealed at their lead-through points.
  • the bimetallic element and / or the counter-contact tongue to shorten the free oscillating length of the Part profiles are formed, in the area of which the parts themselves are rigid, that is, not elastic or movable. If, for example, the mating contact is attached to a long tongue which is mounted on the supporting part at a greater distance from the mating contact, the free-swinging length or the lever arm can be shortened by such profiling. In the area of the profiling, the tongue is practically there and not elastic, it only remains elastic in the unprofiled, shorter area and can swing back into this area.
  • the invention proposes to have contact and counter-contact switched by different bimetallic elements, one in particular being able to have current flowing through it and therefore forming a current-sensitive switch, while the other is electrically unloaded and only responds to the ambient temperature.
  • the bimetallic element which is not affected by the current and is only temperature-sensitive, can act as a thermostat or controller, for example, to regulate the current flow to a cooling device or a heater, while the current-carrying bimetal element fulfills a monitoring function in the event of excessive current flow, for example a short circuit, and in this case causes a separation . It can be set very well at what load, i.e. H. what current flow over which period of time the switching process should start. When coordinating the various switching conditions of the two bimetallic elements, a wide variety of combinations can be selected.
  • the device according to the invention for temperature-dependent switching of an electrical connection has a support part 1 for the essential switching elements in the exemplary embodiment shown.
  • the device can be surrounded by a housing 2, as is the case in the illustrated embodiments; but this need not be so, the device could also be used in a recess in the device to be controlled or monitored or the like, a protruding end plate 3 at one end of the support part 1 completely closing the opening of such a recess.
  • a switch according to the invention could also be used in the recess there.
  • the device according to the invention has a movable contact 6 on the one hand and a mating contact 7 assigned to it on the other hand.
  • the contact 6 is formed at the front end of an elongated, tongue-shaped bimetal element 8, which is fastened with its rear end 9 to a connecting piece 11, for example welded to tongues formed thereon, which merges into a connecting element 12 projecting from the supporting part 1 via its end plate 3 .
  • the contact unit formed by the parts 6, 8, 9, 11 could be fastened to the support part 1, which consists of insulating material, by screwing or riveting in the area of the connecting piece 11.
  • the attachment is carried out in the following manner: the support part 1 has on its two edges from its central section 13 upward and inward projections 14, 14 ', which form groove-shaped undercuts 16, 16' towards the central part 13 ( Figure 3). At the connecting piece 11, edge regions 17, 17 'of the same are bent out of the plane of the actual connecting piece 11 somewhat more than this corresponds to the height of the undercuts 16, 16'.
  • the unit 6, 8, 9, 11, 12 is inserted with its connecting piece 11 and its bent-out edges 17, 17 'into the undercuts 16, 16' formed on the support part 1 in such a way that it is actually connected to the central section 13 of the support part 1 Connecting piece 11 and the edges 17, 17 'resting on the inwardly projecting lugs 14, 14'.
  • This configuration by means of which the mating contact 7 is fixed in a similar manner on the supporting part 1, so that this does not have to be described again in detail, enables assembly of the device according to the invention that is quite simple in terms of production technology and materially economical.
  • the mating contact 7 is formed at the front end of a mating contact tongue 18, which is formed in a transition section 19 in the manner corresponding to the connecting piece 11, described with reference to FIG. 3, and from which it integrally merges into an associated connecting element 21, and such forms a counter-contact unit 7, 18, 19, 21, which, as said, is also fixed to the support part 1 in the manner explained with reference to the contact unit 6, 8, 9, 11, 12.
  • the mating contact tongue 18 consists of an inherently elastic metal part, such as an elastic sheet metal part. Since, as said, it is only fastened in the area of the transition piece 19, the counter-contact 7 can evade a pressure acting on it, in which the counter-contact tongue 18 bends elastically away from the supporting part 1.
  • a profile 22 can be appropriately pronounced on this, as is the case in the exemplary embodiment shown, this profile 22 along its length Mating contact tongue 18 stiffened.
  • FIG. 1 shows the preferred embodiment of the device in a contact interruption position, which generally corresponds to a high-temperature position, in which the temperature is above a predetermined value and a current interruption must therefore take place.
  • the bimetallic element 6 bends as shown in FIG Way and lifts the contact 6 from the counter contact 7, so that there is a power cut. If the temperature now drops below a predetermined value, the bimetallic disc 8 jumps over from its position shown in FIG. 1 and thus brings the contact 6 into contact with the mating contact 7.
  • the bimetallic element 8 bends just so far that the Contact comes into contact with the counter contact 7, whether the contact 6 exerts a greater force on the counter contact 7, so that the latter itself largely remains in its position shown in FIG. 1.
  • the elastically bendable mating contact tongue can now be used due to the elastic mounting of the mating contact 7 18 recede and give way to the force of the Bielement 8 against. This avoids that at such low temperatures the internal stress of the bimetal element becomes extremely large on the one hand, but on the other hand it cannot bend further because its contact rests on a stationary mating contact, causing the high voltages of the bimetal element to damage the bimetal element at these low temperatures itself, plastic changes and in particular considerable switching temperature changes could result.
  • the bimetal element 8 moves or pivots over its entire length from its end 9 attached to the connecting piece 11 to the contact 6.
  • the force of the counter-contact tongue 18 can spring back only in its shorter area between the counter-contact 7 and the front end of the profiling 22.
  • the free spring length of the bimetallic element 8 on the one hand and the counter-contact tongue 18 on the other hand is therefore different. This means that when the contact 6 comes into contact with the counter-contact 7 and the counter-contact 7 is pushed back by the contact 6, the contact 6 and the counter-contact 7 do not always touch with the same points, but they practically migrate and rub against each other.
  • FIGS. 4 to 6 of the device according to the invention have two switching elements instead of one switching element, namely the bimetal element 8 of the embodiment of FIGS.
  • a switching element can bring about temperature control by moving back and forth within certain temperature ranges, while the other switching element, such as the bimetallic element 8, merely monitors temperature, i. H. ensures an interruption at excessively high temperatures.
  • One switching element could also only respond to ambient temperatures, while the other switching element, such as the bimetallic element 8, responds to excessive current flow and causes an interruption of contact due to heat development in it caused by excessive current flow.
  • FIGS. 4 to 6 is explained in detail below, the same reference numerals being used for the parts and elements already described with reference to FIGS. 1 to 3 and, insofar as is not absolutely necessary, no renewed explanation is carried out, but basically insofar reference is made to the explanation of the configuration of FIGS. 1 to 3.
  • the supporting part 1 has on its side facing the counter-contact tongue 18 an annular recess 26 (which is also provided in the configuration of FIGS. 1 to 3, but has no special function there itself) ) with a central centering nose 27.
  • a largely annular bimetallic disc 28 is inserted into this recess between the central part 1 and counter-contact tongue 18, the bimetallic disc 28 being centered by the centering lug 27 and held in place.
  • the bimetallic disc 28 is inserted in such a way that it is unloaded in its low-temperature position (FIG. 6) and in particular allows the counter-contact tongue 18 to come freely into contact with the supporting part 1 while it is in its high-temperature position (FIGS. 5 and 6) its inner circumference rests on the supporting part 1 and with its outer circumference on the mating contact tongue 18 and therefore urges it downward away from the supporting part 1 so as to interrupt the electrical connection to the contact 6.
  • the switching temperature of the bimetallic element 8 of the contact 6 is above the switching temperature of the bimetallic disc 28.
  • the position of the bimetallic element 8 and the bimetallic disc 28 is shown at a temperature which is above both switching temperatures.
  • the bimetallic element 8 lifts the contact 6 upwards and therefore initially causes resulting from an electrical separation.
  • the bimetallic disc 28 pushes the mating contact tongue 18 and with it the mating contact 7 downward and likewise in turn causes electrical isolation of the contacts 6, 7. If, for example, the ambient temperature now drops to a value below the switching temperature of the bimetal element 8, but remains above the switching temperature of the bimetallic disc 28, the bimetallic element 8 snaps from the position of FIG. 4 into the position of FIG.
  • the mating contact 7 can move freely downwards under the acting force of the contact 6, as has already been explained with reference to the configuration of FIGS. 1 to 3.
  • the bimetallic element 8 does not have to switch under the effect of the ambient temperature, but can also switch itself due to the current flow and the temperature increase caused thereby.
  • the bimetallic elements 8, 28 when the two bimetallic elements 8, 28 are arranged such that they move the two contacts 6, 7 apart in their high-temperature positions, their switching temperatures must not be distributed such that the switching temperature of the bimetallic element 8 is higher than that of the bimetallic disc 28. If the switching temperature of the bimetallic disc 28 in the arrangement of the two elements shown is higher than that of the bimetallic element 8, the bimetallic element 8 would still remain in its position corresponding to FIG. 4 at an ambient temperature between the two switching temperatures, while the bimetallic disc 28 and thus the mating contact tongue 18 would take the position of FIG. 6 with its mating contact 7, but the bimetal element 8 would still interrupt the current flow.
  • the two bimetallic elements 8, 28 do not have to be arranged in the manner shown that in their high temperature positions they push the two contacts 6, 7 apart.
  • the bimetallic disc 28 could be arranged such that its position corresponding to FIGS. 4 and 5 is the position below the switching temperature, i.e. the low temperature position and the position shown in FIG. 6 is the high temperature position, while the position of the figures 5 and 6 of the bimetal element 8 is the position for normal current flow and the position of FIG. 4 of the bimetal element 8 is the position for excessive current flow, for example a short circuit.
  • the function would then be such that with normal current flow the bimetallic element 8 with the contact 6 is in the position of FIGS.
  • the bimetallic disc is in the position of FIG. 5 and therefore cuts off the power supply to the cooling device. If the temperature now rises, the bimetallic disc 28 jumps to the position in FIG. 6 and therefore enables the circuit to be closed so that the optionally connected cooling device can work. If an excessive current flows due to a malfunction or the like, the bimetallic element 8 can jump upward from the position of FIG. 6 due to the heat developing therein and detach the connection of the contact 6 to the mating contact 7, although actually from the ambient temperature should turn cool.
  • FIGS. 7 and 8 show a further embodiment of the device according to the invention, which can be used particularly advantageously if the switching elements have to be arranged in a completely tight manner in a housing, as is important, for example, for use in refrigeration compressors, where hermetic sealing of the switching chamber is necessary , because the switch itself is flushed with refrigerant.
  • the embodiment according to FIGS. 7 and 8 also initially generally has a supporting part 1.
  • this supporting part is provided with an outer section designed as a ring 31.
  • Metallic housing covers 32 and 33 are placed on both sides of the ring 31, which are firmly connected to the ring 31 and thus enclose a hermetically sealed chamber 34.
  • the connection and sealing can take place in a wide variety of ways, for example the covers 32, 33 can be flanged at their edges and, if necessary, for this purpose.
  • the ring 31 have corresponding outer grooves in which the flanged edges of the covers 32 and 33 engage.
  • the ring 31 is metallized on its end faces, it being possible, for example, as an insulating aluminum oxide body, and then the housing covers 32, 33 on the ring z. B. are soldered.
  • the housing covers 32, 33 are punctiformly provided with notches 36, 37, on which the bimetallic element 8, which is largely also annular, and on the other hand the counter-contact tongue 18 are then fixed, for example soldered.
  • the supporting part 1 carries the centering lug 27, which centers the centering of the further bimetallic disk 28 acting on the mating contact tongue 18 and thus the mating contact 7.
  • Both housing covers 32, 33 are provided with connecting tongues 38, 39.
  • the free length of the bimetal element 8 or the mating contact tongue 18 can also be selected differently depending on the arrangement and design of the notches 36 and 37 in this embodiment. Except for the constructional differences shown and explained, the embodiment according to FIGS. 7 and 8 acts and functions in the same way as the previously explained embodiments, in particular the embodiments of FIGS. 4 to 6 provided with the second bimetallic disk 28, so that this is dealt with separately saved.
  • the device according to the invention with its basic features enables further modifications and refinements.
  • a current flow through the bimetallic element 8 itself could also be avoided and the contact 6 could be supported in a variety of other ways via movable cutting edge bearings or spring snap disks, which themselves conduct the current in the contact position, while the bimetallic element 28 itself does not carry the current leads, but only effects the switching process.
