Definitions

  • the present invention relates to a temperature-dependent switch with a housing having a cover part with an upper side and a lower part with a circumferential, raised wall, wherein between the lower part and the cover part, an insulating film is arranged, which extends with its edge region to the top of the cover part , And the wall of the lower part is bent over on the upper side and thereby holds the lid part with the interposition of the insulating film on the lower part, and arranged in the housing with a temperature-dependent switching mechanism, depending on its temperature, an electrically conductive connection between two outside of the housing provided contact surfaces manufactures or opens.
  • Such a switch is from the DE 196 23 570 A1 known.
  • the switch is electrically connected via the soldered to its 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 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 flanged edge of the base firmly on this shoulder.
  • cover part and lower part are made of electrically conductive material, between them an insulating film is provided which extends parallel to the cover part and is pulled up laterally, so that its edge region extends to the top of the cover part.
  • the temperature-dependent switching mechanism here comprises a spring snap-action disk, which carries the 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.
  • the first external connection is a contact surface, which is arranged centrally on the cover 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 bimetal disc is provided for the temperature-dependent switching function, which rests below its critical temperature without force in the switching mechanism, wherein it is arranged geometrically between the contact part or the contact bridge and the spring snap-action disc.
  • a bimetal part is understood to be 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. If the temperature changes beyond its response temperature or below its return temperature snap the bimetal parts 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 or 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.
  • the bimetallic disc can take over the function of the spring snap-action disc.
  • temperature-dependent switches which, as the current transmission element, have no contact plate but a spring part which carries the two mating contacts 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 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 is made of PTC thermistor, 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 known switches are therefore often used in enclosing or protective caps that serve the mechanical and / or electrical protection and often the case should also protect against the entry of impurities. Examples of this can be found for example in the DE 91 02 841 U1 , the DE 92 14 543 U1 , of the DE 37 33 693 A1 and the DE 197 54 158 ,
  • the known switches are often provided after soldering the connecting cables with a impregnating varnish or protective varnish.
  • the lid part is provided with a bead in the aforementioned switch, with which it penetrates into the insulating film when flanging the wall of the lower part. Although this ensures a better seal, in many cases, however, penetrates paint into the interior of the housing.
  • the present invention seeks to eliminate in the known switch in a structurally simple and inexpensive way, the above-mentioned problems, at least reduce.
  • the insulating film has at least two radially extending slots in its edge region.
  • the inventor of the present application has recognized that the problems with the tightness of the known switch are due to the fact that the insulating sheet curls or wrinkles when bent on the top of the lid member, resulting in that the wall of the lower part not far enough on the top of the lid part can be bent. Furthermore, this waviness of the insulating foil on the upper side and on the peripheral end side of the lid part causes creepage paths for liquids to form, so that when impregnating the known switch with protective lacquers they can creep into the interior of the switch.
  • the flanged edge of the lower part does not seal the upper side so well that in any case it is ensured that no liquid can enter the interior of the switch during resinification.
  • the edge region is, so to speak, peripherally divided into different sections which are separated from one another by the slots.
  • the edge regions push on the slots then one above the other, so that the insulating no longer waves but flat against the front and on the top.
  • the slots are circumferentially distributed uniformly over the edge region, wherein preferably at least three slots are provided circumferentially distributed over the edge region.
  • the even distribution of at least three slots provides three portions of the edge area, which provides for a good flat application of the insulating film on the top of the lid member and also unexpectedly prevents the insulating foil curled around the front side of the lid part.
  • At least one slot opens radially outward in a V-shape.
  • the slot has an opening angle of at least 30 °, wherein the opening angle is preferably between 30 ° and 90 °, more preferably between 40 ° and 60 °.
  • the slots have a depth which is less than the width of the edge region.
  • the slots do not reach around the top of the lid part around to the front side of the lid part, which is advantageous in view of the required dielectric strength.
  • V-shaped slots have an opening angle of about 50 ° degrees and about about half of the over the front side of the lid part protruding edge region extend.
  • the insulating film consists of polyimides, preferably of aromatic polyimides such as Kapton®.
  • Insulating films made of these materials are characterized by the fact that they are "drawable”, so slightly stretch when inserting the lid part in the lower part, and that they can still be folded well around the front side of the lid part on the top, and further the required Dielectric strength is achieved.
  • an insulating protective film is arranged on the upper side, which extends to below the edge region of the insulating film, the protective film preferably extending beyond the slots beyond the edge region.
  • a protective film which preferably rests flat on the top, so when bending the raised wall of the base on the top causes no undesirable back pressure. If this protective film is led to below the edge region, so that the slots begin so to speak only above this protective film, according to the inventors for a particularly good mechanical seal and electrical insulation between the lower part and the cover part and provided to the outside.
  • the protective film preferably consists of aromatic polyamides, more preferably Nomex®.
  • Aromatic polyamides are characterized by a special dielectric strength.
  • a protective layer preferably a protective lacquer is applied.
  • This measure is used after soldering the leads to protect the ready-made switch in use, where it is wrapped, for example, in the winding of a motor, from penetrating oils, etc.
  • protective coatings while conventional protective coatings are used, as they are also used to protect populated printed circuit boards.
  • the cover part and further preferably the lower part are made of electrically conductive material, wherein more preferably 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 with a the upper surface arranged contact surface cooperates.
  • the derailleur can have a bimetallic part, which carries the movable contact part and thus carries the current through the switch.
  • the bimetallic part may be a round, preferably circular bimetal snap-action disc, wherein it is also possible to use as bimetallic an elongated, cantilevered bimetallic spring.
  • the rear derailleur additionally has a spring snap-action disc, which then carries the movable contact part and the current through leads the closed switch and ensures the contact pressure in the closed state.
  • the bimetallic part is relieved of both the current conduction and the mechanical load when closed, which increases the life of the switch and ensures that the switching temperature is long-term stable.
