Definitions

  • the present invention relates to a temperature-dependent switch with a housing which has a cover part with an upper side and a lower part with a raised, circumferential wall, the upper section of which is bent over onto the upper side of the cover part and thereby holds the cover part to the lower part, wherein two contact surfaces are provided on the outside of the housing and a switching mechanism is arranged in the housing which is designed to switch, depending on its temperature, between a closed state in which the switching mechanism establishes an electrically conductive connection between the two contact surfaces, and an open state in which the switching mechanism opens the electrically conductive connection between the two contact surfaces, wherein a sealing ring is arranged on the upper side of the cover part and is in sealing contact with the bent over, upper section of the wall.
  • a temperature-dependent switch according to the preamble of claim 1 is known from FR 2 114 918 A5 Further examples of temperature-dependent switches are known from DE 196 23 570 A1 and the DE 10 2011 104 984 A1 known.
  • Such temperature-dependent switches are used in a conventional manner to monitor the temperature of a device.
  • the switch is brought into thermal contact with the device to be protected, for example, via one of its outer surfaces, so that the temperature of the device to be protected influences the temperature of the switching mechanism.
  • the switch is electrically connected in series into the supply circuit of the device to be protected via connecting cables that are firmly attached to its outer contact surfaces (e.g. by soldering or welding), so that below the response temperature of the switch, the supply current of the device to be protected flows through the switch.
  • the known switch has a deep-drawn base with an inner circumferential shoulder on which a cover rests. The cover is held firmly on this shoulder by a raised and flanged edge of the base.
  • the cover and base are made of electrically conductive material. Therefore, an insulating foil is provided between them, which runs parallel to the cover and is laterally extended upwards so that its edge extends to the top of the cover.
  • the flanged edge i.e., the bent upper section of the wall of the base, presses against the cover in this switch with the insulating foil in between.
  • the insulating foil thus serves to electrically insulate the two electrically conductive housing parts of the switch.
  • Known switches also include a temperature-dependent switching mechanism, which has a spring-loaded snap-action disc carrying a movable contact part, as well as a bimetallic disc placed over the movable contact part.
  • the spring-loaded snap-action disc presses the movable contact part against a stationary counter-contact located inside the cover part.
  • the edge of the spring-loaded snap-action disc rests against the lower part of the housing, so that the electrical current flows from the lower part through the spring-loaded snap-action disc and the movable contact part into the stationary counter-contact and from there into the cover part.
  • the first external connection is a contact surface located centrally on the cover.
  • the second external connection is a contact surface located on the flanged edge of the base. However, it is also possible to position the second external connection not on the edge, but rather on the side of the current-carrying housing or on the underside of the base.
  • the cover part is therefore preferably made of an insulating material or a PTC thermistor.
  • PTC thermistors are also referred to as PTC resistors. They are made, for example, from semiconducting, polycrystalline ceramics such as barium titanate (BaTiO 3 ).
  • This design is chosen especially when very high currents have to be switched, which can no longer be easily conducted via the spring washer itself.
  • a bimetallic disc is provided for the temperature-dependent switching function, which lies force-free in the switching mechanism below its transition temperature, whereby it is geometrically arranged between the movable contact part or the contact bridge and the spring snap disc.
  • a bimetallic part is understood to be a multi-layer, active, sheet-metal component consisting of two, three, or four inseparably connected components with different thermal expansion coefficients.
  • the individual layers of metals or metal alloys are bonded or positively connected and are achieved, for example, by rolling.
  • bimetallic parts exhibit a first stable geometric conformation in their low-temperature position and a second stable geometric conformation in their high-temperature position, between which they switch depending on the temperature in a hysteresis manner.
  • the bimetallic parts snap into the respective other conformation.
  • the bimetallic parts are therefore often referred to as snap disks, and they can have an elongated, oval, or circular shape when viewed from above.
  • the bimetallic disc changes its configuration and works against the spring snap disc in such a way that it lifts the movable contact part from the stationary contact or the contact bridge/current transfer element from the two stationary counter contacts, so that the switch opens and the device to be protected is switched off and cannot heat up any further.
  • the bimetallic disc is mechanically supported without force below its transition temperature, whereby the bimetallic disc is also not used to conduct the current.
  • the bimetallic snap-action disc can also take over the function of the spring snap-action disc and possibly even the current transmission element, so that the switching mechanism only comprises one bimetallic disc, which then carries the movable contact part or has two contact surfaces instead of the current transmission element, so that the bimetallic disc not only ensures the closing pressure of the switch, but also carries the current when the switch is closed.
  • a bimetallic spring clamped on one side can also be used, which carries a movable contact part or a contact bridge or a current transmission element.
  • temperature-dependent switches can also be used that do not have a contact plate as the current transfer element, but rather a spring element that carries the two mating contacts or on which both mating contacts are formed.
  • the spring element can be a bimetallic part, in particular a bimetallic snap disc, which not only provides the temperature-dependent switching function but also simultaneously ensures the contact pressure and conducts the current when the switch is closed.
  • the known switches are therefore often used in enclosures or protective caps, which serve as mechanical and/or electrical protection and often also protect the enclosure from the ingress of contamination. Examples of this can be found in the DE 91 02 941 U1 , dem DE 92 14 543 U1 , the DE 37 33 693 A1 and the DE 197 54 158 A1 .
  • DE 41 43 671 A1 known to overmold the external connections with a one-component thermoset.
  • DE 10 2009 039 948 It is known to cast terminal lugs with an epoxy resin.
  • enclosures or terminal caps is often considered to be too complex in terms of construction and unsatisfactory in terms of thermal connection to the protective device.
  • switches are often coated with a varnish or protective coating.
  • Some switches are also provided with resin caps, which, however, significantly increase the overall height of the switch. Furthermore, it is often impossible to ensure that the resin will flow completely. There is also a risk that the resin will penetrate open gaps and then enter the interior of the switch.
  • the flanged edge of the base does not seal the top surface sufficiently to ensure that no liquid can penetrate the switch during resinification. This is particularly problematic because such leakage paths are barely visible from the outside and therefore difficult to detect through visual inspection alone.
  • a sealing ring is arranged on the upper side of the lid part, preferably before the upper section of the raised, circumferential wall of the lower part is bent or flanged, which sealing ring is in sealing contact with this upper wall section after the bending or flanged thereof.
  • the sealing ring provided according to the invention also guarantees an extremely good mechanical seal which prevents the penetration of such varnishes or resins into the interior of the switch.
  • the inventive solution also has immense advantages from a production-technical perspective.
  • the individual components of the housing do not need to be provided with punched burrs or a bead to ensure mechanical sealing.
  • the sealing ring simply has to be placed on the top of the cover part. preferably before the upper section of the wall is beaded. This can be done fully automatically.
  • the upper section of the wall penetrates at least partially into the sealing ring with its free circumferential front edge.
  • the sealing ring is partially destroyed by the penetration of the wall, the mechanical seal is further improved by the penetration of the wall at the sealing point, as an additional mechanical/physical barrier is created.
  • an insulating film can also be used in the switch according to the invention. This is particularly preferred when both the cover part and the lower part of the housing are made of an electrically conductive material and the two housing parts must be electrically insulated. In such a case, however, the insulating film primarily performs the function of electrically insulating the two housing parts, since the mechanical seal, as already mentioned above, is achieved according to the invention via the sealing ring, which is in sealing contact with the bent, upper section of the wall.
  • the sealing point at which the sealing ring is arranged is free of the insulating film.
  • the sealing ring is integrally connected to the upper side of the lid part and/or the bent upper section of the wall.
  • the sealing ring is integrally connected to both the upper side of the lid part and the bent upper section of the raised wall of the lower part.
  • This material-to-material connection further improves the sealing effect achieved by the sealing ring. From a manufacturing perspective, such a material-to-material connection can be produced very easily and cost-effectively.
  • the sealing ring is glued, hot-stamped or welded to the upper side of the cover part and/or the bent upper section of the wall by means of a welded joint produced by means of ultrasonic welding.
  • Ultrasonic welding allows a clean and permanent connection of the sealing ring to the top of the lid and/or the bent edge of the upper section of the wall of the base. This significantly improves the sealing effect at these connection points.
  • a further advantage is that, unlike gluing the aforementioned components, the ultrasonic welding process can be performed even after the sealing ring has been mounted on the top of the cover part and the upper section of the wall of the base part has been bent or flanged. This simplifies production handling considerably.
  • a further advantage is that ultrasonic welding requires no filler metals. This allows for compact weld seams. Furthermore, the environmental impact is significantly reduced, as the use of environmentally harmful materials can be completely avoided.
  • ultrasonic welding the components to be joined are welded using high-frequency mechanical vibration.
  • the resulting vibration leads to heating between the components due to molecular and interfacial friction.
  • ultrasonic welding is also suitable for joining a metal component to a plastic component, as is the case here with the switch housing and the sealing ring.
  • a generator In ultrasonic welding tools, a generator generates electronic vibrations, which are converted into mechanical vibrations by an ultrasonic converter. These vibrations are transmitted to the components to be joined via a so-called sonotrode. Within fractions of a second, the resulting ultrasonic vibrations generate frictional heat at the joining surfaces of the components to be joined, melting the material and bonding the components together.
  • the parameters to be adjusted during ultrasonic welding can be adjusted to suit the specific circumstances.
  • the parameters to be adjusted and their respective values are known to the expert and can be found in the relevant standards.
  • the sealing ring is designed as a circular plastic ring.
  • the cross-section of the sealing ring can be chosen arbitrarily, for example, circular (O-ring), triangular (delta ring), rectangular, square (quad ring), or oval. More complex cross-sectional shapes are also conceivable.
  • the sealing ring can also be a standard flat gasket.
  • sealing materials such as fluoroplastics, polyaryletherketones, polyamides, polyacetals or polyethylenes, can be considered as materials for the sealing ring.
  • the upper section of the wall is bent by at least 90°, preferably by at least 120°, when viewed in a cross-section.
  • the upper section of the wall can also be bent or curved by approximately 180°, forming a circumferential bead that is, for example, U-shaped in cross-section.
  • a circumferential bead that is, for example, U-shaped in cross-section.
  • the lower part and the cover part are each made of electrically conductive material and that an insulating film is arranged between the cover part and the lower part.
  • a first of the two contact surfaces is arranged on the cover part and a second of the two contact surfaces is arranged on the lower part, and that the switching mechanism carries a movable contact part which cooperates with a stationary counter-contact which is arranged on an inner side of the cover part and interacts with the first of the two contact surfaces.
  • the lower part is made of electrically conductive material and the cover part is made of insulating material or PTC material.
  • the two contact surfaces can be arranged on the cover part, and the switching mechanism can carry a current transmission element that interacts with two stationary counter-contacts arranged on an inner side of the cover part and each interacting with one of the two contact surfaces.
  • a basic switch structure corresponds, for example, to the structure shown in DE 198 27 113 C2 is known.
  • the switching mechanism has a bimetallic part which carries a movable contact part and thus conducts the current through the switch.
  • the bimetal part can be a round, preferably circular bimetal snap-action disc, although it is also possible to use an elongated bimetal spring clamped on one side as the bimetal part.
  • the switching mechanism also has a spring-loaded snap-action disc, which then supports the movable contact part and conducts the current through the closed switch, providing the contact pressure when closed. This relieves the bimetallic part of both the current conduction and the mechanical stress when closed, which increases the service life of the switch and ensures that the switching temperature remains stable over the long term.
  • the present invention is particularly suitable for round temperature-dependent switches, which are therefore round, circular or oval when viewed from a top view of the lower part, although other housing shapes can also be used according to the invention.
