Definitions
- the invention relates to a temperature-dependent switch for opening and closing a circuit as a function of the temperature of a bimetal part, with an electrically conductive housing part which has an underside, an electrically conductive cover part for closing the housing part, an insulating washer arranged between the housing part and the cover part, which the housing part electrically opposite the cover part insulated, and a switching mechanism arranged in the housing part, which produces or opens an electrical contact between the housing part and the cover part depending on the temperature of the bimetal part, the circuit being connectable on the one hand to the cover part and on the other hand to the housing part.
- the known switches are used to monitor the temperature of a device. For this purpose, for example, they are brought into contact with the winding of a motor via their underside, so that the temperature of the winding influences the temperature of the bimetal part. If the switching temperature is exceeded, the switch mechanism opens the connection between the cover part and the housing part and the circuit above it is interrupted. If the temperature drops, the circuit is closed again, although this does not necessarily have to be the case; bistable temperature-dependent switches are also known.
- the known switches are usually assembled with connecting leads, which are soldered on the one hand to the cover part and on the other hand to an edge of the housing part.
- the bottom of the housing part is not available for connecting a stranded wire because this would hinder the temperature transition to the monitored device. But even in such switches in which the underside of the housing part is not in direct contact with a monitored device, a connection on the underside of the housing part is undesirable because this would lead to a greater height of the temperature-dependent switch.
- the cover part is inserted into the housing part and the raised edge of the housing part is flanged so that it clamps the cover part firmly.
- the stranded wire which makes contact with the housing part is then soldered to this flanged edge.
- the second lead is soldered directly onto the cover part.
- a similar temperature-dependent switch is known from DE-OS 21 21 802, which has a two-part housing.
- a connection tab is provided on the cover part and on the housing part, which is possible there because of the two-part housing.
- the upper housing part overlapping the lower housing part is provided with a recess in its peripheral edge through which the connecting lug of the lower housing part extends outwards.
- the generic switch has the advantage that the cover part is inserted into a housing part, which leads to greater pressure stability, but has the disadvantage that the leads must be soldered.
- the insulating washer is placed separately from the upper housing part, so that the insulating washer, which has a very low weight, can easily slip during manufacture.
- the switching mechanism has a spring washer, into which a contact part is inserted, which comes into contact with the upper housing part.
- a bimetallic snap disk is placed over the spring washer, which is accommodated in the housing without forces below the switching temperature. The current flows through the conductive upper housing part, the contact part, the spring washer and the lower housing part, on which the spring washer is supported. If the switching temperature is exceeded, the bimetallic snap disk snaps and presses the spring washer with its contact away from the upper housing part.
- the contact part is provided with a ring, via which it is clamped between the spring washer and the bimetallic snap disk.
- the contact part must be inserted, so to speak, "loosely” so that no mechanical stresses or forces are exerted on the spring washer, which would otherwise influence their movements.
- this object is achieved in the case of the temperature-dependent switch mentioned at the outset in that the housing part is provided with an outer shoulder set back from the underside for connecting a stranded wire or a connecting lug.
- a stranded wire can now be connected to this shoulder, which is set back relative to the underside, without this influencing the overall height or the temperature contact possibly made via the underside of the housing part.
- the wire can now not only on the cover part but also on the shoulder e.g. can be welded by electro spot welding, which is considerably faster than the soldering known from the prior art.
- the measure of providing the shoulder already leads to a significant improvement in the manufacture and assembly of the new temperature-dependent switches.
- the switching mechanism comprises an electrically conductive spring washer, which works against the bimetal part depending on the temperature, is supported on the housing part and carries a contact part which, depending on the temperature of the bimetal part, is in contact arrives with the cover part and thus establishes the electrical contact between the housing part and the cover part, the bimetallic part preferably being a bimetallic snap disk.
- the contact part is preferably firmly attached to the spring washer by welding.
- connection lug is provided which is connected to the shoulder by its first end, preferably by welding, and whose second end, remote from the first end, serves as a connection.
- Another advantage here is that because of the small thickness of the connecting lug, the shoulder only has to be set back slightly from the underside, which further reduces the overall height. The wire can then be welded to the second end of this terminal lug. Although two welding processes are required here to establish the connection between the strand and the housing part, this takes place overall in a considerably shorter time than that from the stand the soldering of the strand, known in the art, to the flanged edge of the housing part.
- Another advantage here is that the mechanical tensile strength in the new connection made via the connecting lug is considerably better than in the case of the soldered connection at the flanged edge.
- the shoulder is a circumferential ring shoulder and the first end of the connecting lug is annular.
- connecting lug is angled such that its second end is set back relative to the shoulder.
- the prefabricated switch advantageously has a low overall height, since the connecting lug and the wire do not project above or below the switch.
- connection lug which is connected to the cover part by its first end, preferably by welding, and whose second end, remote from the first end, serves as a connection.
- connection lug This has the same advantages as with the first connection lug, the overall height of the switch is reduced again.
- connecting lug which has a very small thickness, has to be welded onto the cover part, while the stranded wire can be welded outside the contour of the switch in order to enable connection to the circuit.
- the further terminal lug is angled such that its second end is set back from the first end.
- the two connecting lugs are stamped parts, preferably made of sheet metal.
- the advantage here is that the connecting lugs themselves can be produced quickly and inexpensively, so that the overall costs for the manufacture and assembly of the new switch are significantly reduced compared to the prior art.
- the housing part is a deep-drawn housing part.
- Such a deep-drawn housing part is very inexpensive to manufacture, so that the overall costs in the manufacture of the new switch are advantageously reduced.
- a mating contact for the contact part is provided in the cover part.
- the advantage here is that a low contact resistance between the spring washer and the cover part is made possible in an inexpensive and simple manner.
- the second terminal lug and the mating contact are welded on in one operation.
- the insulating washer is already fixed to the cover part before the switch is assembled.
- the insulating disk is glued to the cover part at least in sections.
- the cover part and the insulating washer can first be manufactured separately and then glued together.
- the required center hole can be made in the insulating washer, through which the contact part of the spring washer can come into contact with the cover part or the mating contact attached to it.
- the latter possibility namely to first glue a sheet and an insulating paper to one another, has a surprising advantage in production, because not only does the positioning between the insulating washer and cover part during assembly fall, but also the alignment during the prior fixing of the insulating washer to the invention Cover part away.
- 10 is a temperature-dependent switch for temperature-dependent opening and closing of a circuit.
- the switch 10 comprises a housing part 12 which, with its underside 13, connects to a device (not shown in FIG. 1) or e.g. the excitation winding of a motor can be applied so that the temperature of the device or the motor influences the switching behavior of the switch in a manner to be described in more detail.
- the housing part 12 has a raised edge 14 and essentially has a circular plan.
- a switching mechanism 15 which, depending on the temperature of the monitored device, makes or opens an electrical contact between the housing part 12 and a cover part 16.
- An insulating disk 17 is arranged between the cover part 16 and the housing part 12 and electrically insulates the housing part 12 from the cover part 16.
- the insulating washer 17 is folded up around the cover part 16 in FIG. 1, so that it insulates the cover part 16 along its entire circumference 18 from the edge 14.
- the inserted in the raised edge 14 cover part 16 and the insulating washer 17 are held in the housing part 12 in that the edge 14 is flanged at its upper end 19. In this way, the switching mechanism 15 is tightly received in the switch 10, an edge region 20 of the insulating disk 17 projecting upward.
- the switching mechanism 15 comprises a spring washer 21 to which a contact part 22 is welded.
- this contact part 22 extends through a central hole 23 in the insulating disk 17 up to a mating contact 24 which is welded to the cover part 16 on the inside.
- the spring washer 21 presses the contact part 22 against the counter contact 24 and thus ensures a low contact resistance between these two contacts.
- the spring washer 21, on the other hand, is supported in the interior of the housing part 12 on a circumferential bead 25. Since both the housing part 12, as well as the cover part 16 and the spring washer 17 are made of electrically conductive material, the switching mechanism 15 establishes an electrical contact between the housing part 12 and the cover part 16 in this way.
- a bimetallic part 26 is arranged between the spring washer 21 and the insulating washer 17, which is here a bimetallic snap disc 27 which likewise has a central hole through which the contact part 22 extends.
- the bimetallic snap disk 27 In the position shown in Fig. 1, the bimetallic snap disk 27 is without power, the switching temperature has not yet been reached. If the temperature of the monitored device increases, this will e.g. transmitted via the bottom 13 or via the connections. This also increases the temperature of the bimetallic snap disk 27, so that it snaps and presses the spring washer 21 downward in FIG. 1, so that the contact part 22 is released from the mating contact 24 and opens the electrical contact between the housing part 12 and the cover part 16.
- the switch 10 described so far is provided with connecting leads 31, of which only the connecting lead 31 a is shown in FIG. 1, which has its stripped end 32 on the cover part 16 is welded on.
- the contact to the housing part 12 takes place via a connecting lug 33 which is ring-shaped at one end 34.
- the connecting lug 33 is supported on an outer circumferential shoulder 35 of the housing part 12, which is set back relative to the underside 13.
- the extent of the shoulder 35 being set back and the thickness of the connecting lug 33 are selected such that the connecting lug 33 does not protrude downward beyond the housing part 12 in the region of its annular end 34. In this way, a low overall height is made possible and, on the other hand, the underside 13, if desired, can be supported directly on the device to be monitored, which ensures good heat transfer.
- first connecting lug 33 is angled such that its second end 36, which is remote from the first end 34, is set back relative to the shoulder 35. At this second end 36, the further connecting cord, which cannot be seen in FIG. 1, is attached.
- FIG. 2 shows a temperature-dependent switch 10 ', in which the connection to the cover part 12 also takes place via a further connecting lug 38.
- the second connecting lug 38 is welded with its first end 39 to the outside of the cover part 16 and further angled such that its second end 40, which is remote from the first end 39, is set back in relation to the first end 39 in FIG. 2.
- the arrangement is such that the second end 40 of the second connecting lug 38 is radially offset, but is approximately at the same height as the second end 36 of the first connecting lug 33.
- the switch 10 ' corresponds to the switch 10 from FIG. 1. Only the center hole 23 of the insulating disk 17 is made larger in the switch 10' than in the switch 10.
- the cover part 12, to which the insulating washer 17 is glued in a manner to be described in more detail, is first provided with the mating contact 24 and the second connecting lug 38 before it is pressed into the housing part 12. Thereafter, the raised edge 14 is flanged at its upper end 19, whereupon the manufacture of the switches 10, 10 'has ended.
- the connecting leads 31 are welded onto the second ends 36 and 40 of the connecting lugs 33 and 38, respectively. This welding takes place outside the outline contour of the switch 10 'and can be implemented in a simple, quick and inexpensive manner by welding, preferably by means of electric spot welding.
- the assembly of the switches 10, 10 ′ is carried out by the insulating disk 17 fixed to the cover part 16 prior to production and by the contact part 22 attached to the spring washer 21. very simple, no complex positioning is required. Because all fastenings can be produced by welding, not only the manufacture, but also the assembly with connecting leads 31 can be carried out simply, quickly and inexpensively.
- FIG. 3 the switch 10 of Fig. 1 is shown in a plan view from above, so that in addition to the connecting wire 31a, the connecting wire 31b can be seen, which is welded with its stripped end 32b to the second end 36 of the first connecting lug 33 .
- FIG. 4 shows the switch 10 'from FIG. 2 in a top view, the welded connecting leads 31a and 31b being shown here.
- Fig. 5 shows the first terminal lug 33 and the second terminal lug 38, which are manufactured as inexpensive stamped parts, preferably made of sheet metal.
- the connecting lugs 33 and 38 are connected via connecting webs 41 and 42 to a transport web 43 in which transport holes 44 are provided. 5 is only a partial illustration, the transport web 43 is extended upwards and downwards in FIG. 5 and carries further connecting lugs 33 and 39 there.
- the sheet metal 47 with the sheet 48 glued thereon is further processed in a pressing and stamping process with a controlled depth of cut, so that the cover part 16 shown in FIG. 7 with the insulating disk 17 adhered thereto is produced.
- Fig. 7 it can be seen that the insulating disc 17 with its edge region 20 protrudes beyond the circumference 18 of the cover part 16. This edge region 20 folds upwards when the cover part 16 is introduced into the housing part 12 and ensures the lateral insulation between the cover part 16 and the housing part 12.
