Definitions

  • the present invention relates to a temperature-dependent switch having a housing which comprises a cover part with a bottom and a top side and an electrically conductive bottom part with a peripheral shoulder and a peripheral wall, the upper portion of which engages over the cover part, with at least one on top of the cover part arranged first outer contact surface, at least one externally provided on the outside of the housing second outer contact surface, wherein the lid portion cross-upper portion of the circumferential wall of the lower part presses the lid part on the peripheral shoulder, and arranged in the housing with a temperature-dependent switching mechanism, in response to its temperature establishes or opens an electrically conductive connection between the first and the second outer contact surface, wherein a sealing means is provided between the cover part and the lower part.
  • Such a switch is from the DE 196 23 570 A1 known.
  • the known temperature-dependent switch is used in a conventional manner to monitor the temperature of a device. For this purpose, for example, it is brought into thermal contact with the device to be protected via one of its outer surfaces, so that the temperature of the device to be protected influences the temperature of the derailleur.
  • the switch is electrically connected via the soldered to its two outer contact pads leads in series in the supply circuit of the device to be protected, 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 or rotated lower part, in which an inner circumferential shoulder is provided, on which a lid part rests.
  • the lid part is held by a raised and at its upper portion radially inwardly bent circumferential wall of the base firmly on this shoulder.
  • cover part and lower part are made of electrically conductive material, an insulating film running around the cover part is provided between them, which extends inside the switch parallel to the cover part and is pulled up laterally, so that its edge region except for the top the lid part extends.
  • the bent upper portion of the peripheral wall of the lower part rests on the edge region of the insulating film.
  • the temperature-dependent switching mechanism here comprises a spring snap-action disk, which carries a movable contact part, as well as a bimetallic disk which is put over the movable contact part.
  • the spring snap-action disc presses the movable contact part against a stationary counter contact on the inside of the cover part.
  • the spring snap-action disc With its edge, the spring snap-action disc is supported in the lower part of the housing, so that the electric current flows from the lower part through the spring snap-action disc and the movable contact part into the stationary counter-contact and from there into the cover part.
  • first outer terminal is a first outer contact surface, which is arranged centrally on the cover part.
  • second outer terminal provided on the bent wall of the lower part second outer contact surface. But it is also possible to arrange the second outer terminal not at this edge but laterally on the current-carrying housing or on the underside of the lower part.
  • This design is particularly chosen when very high currents must be switched, which can not be easily passed through the spring washer itself.
  • a bimetallic disc is provided for the temperature-dependent switching function, which rests without forces in the derailleur below their critical temperature.
  • a bimetal part is understood as meaning a multilayer active sheet-metal component made of two, three or four components which are inseparably connected to one another and have different coefficients of expansion.
  • the connection of the individual layers of metals or metal alloys are cohesively or positively and are achieved for example by rolling.
  • bimetallic parts In their low-temperature position, such bimetallic parts have a first and their high-temperature position have a second stable geometric conformation, between which they change over in a temperature-dependent manner in the manner of a hysteresis. When the temperature changes beyond its response temperature or below its return temperature, the bimetal parts snap over into the other conformation.
  • the bimetal parts are therefore often referred to as snap disks, wherein they can have an elongated, oval or circular shape in plan view.
  • the bimetallic disc changes its configuration and works against the spring snap-action disc, that they are the movable contact part of the stationary mating contact and the current transfer member of the two stationary mating contacts lifts, so that the switch opens and the device to be protected is turned off and can not heat up.
  • the bimetallic disc is mounted mechanically free of forces below its transition temperature, wherein the bimetallic disc is not used to guide the flow.
  • bimetallic discs have a long mechanical life, and that the switching point, so the critical temperature of the bimetal disc, not changed even after many switching cycles.
  • the bimetallic snap disk can also take over the function of the spring snap-action disc and possibly even the current transfer member, so that the switching mechanism comprises only one bimetallic disc, which then the movable Contact part carries or instead of the power transmission member has two contact surfaces, so that the bimetallic disc not only ensures the closing pressure of the switch, but also leads the power in the closed state of the switch.
  • temperature-dependent switch which have no contact plate as a current transfer member but a spring member which carries the two mating contact or on which the two mating contacts are formed.
  • the spring member may be a Bimetallteil, in particular a bimetallic snap disk, which not only provides the temperature-dependent switching function, but at the same time also provides the contact pressure and the current leads when the switch is closed.
  • the bimetallic disc can take over the function of the spring snap-action disc.
  • the PTC thermistor cover is electrically connected in parallel to the two outer terminals, so that it gives the switch a self-holding function.
  • PTC thermistors are also referred to as PTC resistors. They are made, for example, from semiconductive, polycrystalline ceramics such as BaTiO 3 .
  • the cover part made of PTC thermistor material, so that it also has a self-holding function.
  • the outer heads form the two outer terminals, and interact their inner heads as a stationary mating contacts with the contact bridge.

  • the radially inwardly bent upper portion of the peripheral wall of the lower part presses with the interposition of the insulating film flat on the cover part.
  • the housing is typically protected from the entry of contaminants by a seal which is applied before or even after the connection of terminal lugs or connecting leads to the external terminals.

  • the DE 10 2013 102 089 B4 describes a switch, as in principle from the above-mentioned DE 196 23 570 A1 is known.
  • This switch has between the shoulder in the lower part and the cover part on a spacer ring, which allows a larger switching distance between the movable contact part and stationary counter contact.
  • the edge region of the insulating disk is cut from the outside in a V-shaped manner, whereby the waviness is greatly reduced, so that the tightness is improved.
  • the DE 10 2013 102 006 B4 also describes a switch, as in principle from the above-mentioned DE 196 23 570 A1 is known.
  • This switch is like the one from the DE 195 17 310 A1 Known switch on a cover part of PTC thermistor material. Because of the lack of pressure stability of this PTC cover, can not be effected by the radially inwardly bent upper portion of the peripheral wall of the lower part of a sufficient seal of the known switch against the entry of impurities, so the bent upper portion of the peripheral wall in the from the DE 195 17 310 A1 known switch must be sealed against the top of the lid part with silicone, which often causes problems.
  • the DE 10 2013 102 006 B4 solves this problem in that a cover sheet is provided, which rests only on the top of the PTC lid, and in which the bent and flat on the cover sheet auffode upper portion of the peripheral wall of the base penetrates.
  • the end face of the upper portion of the peripheral wall faces away from the cover sheet.

  • the sealing means has a circumferentially closed circumferential cutting burr, which is arranged on the shoulder in the lower part, and that the cover part consists of electrically insulating material and with its underside directly rests on the shoulder, wherein the cutting ridge protrudes from the bottom into the lid part.
  • This preferably circumferentially self-contained Schneidgrat penetrates during the assembly of the new switch in the lid part and thus ensures a secure seal between the inside of the lower part circumferential shoulder and the lid part.
  • the cutting burr may be formed bead-shaped, but is preferably formed triangular in cross-section, with its shape is adapted to the material in that it penetrates during assembly of the new switch.
  • the cutting burr is generated in the manufacture of the lower part, it is integrally formed with the shoulder.
  • the cutting burr can be produced during deep drawing, stamping or turning of the lower part.
  • a seal is produced by the cutting burr acting between the shoulder and the cover part, which does not act on an insulating film or sealing film by pressure of the bent wall, but by penetration of the cutting burr into the cover part above it, so that the cutting burr produces a mechanical barrier represents.
  • the sealing effect is thus achieved by a structural element, which is a mechanical obstacle to penetrating pollution, so safely restrains both particles and fluids.
  • the sealing effect is effected in contrast to the previously pursued in the prior art strategies not primarily between an insulating film and the lid part but between the lid part and arranged on the lower cutting burr.
  • the inventor of the present application has recognized that the problems with the tightness of the known switches are due to the fact that the insulating sheet curls or wrinkles when bent on the top of the lid part. This leads to creepage paths for liquids not only - as previously assumed - arise between insulating film and cover part but primarily between insulating and circumferential wall of the base, so that when impregnating the known switch with protective coatings on both sides of the insulating film in the interior of the switch can crawl.
