- the invention relates to a temperature switch, in particular an adjustable temperature controller, according to the generic term of claim 1.
- a generic temperature switch has a temperature sensitive Expansion element that has a power transmission acts on a switch spring of a snap switch. There is also an overload protection for the switching spring intended.
- the overload protection has at least one Buffer with the force transmission between the expansion element and switching spring cooperates, especially in the Power flow of the power transmission is installed.
- the buffer is above one of the actuating force of the switch spring in Limit force assigned to the switching point can be changed or compliant while he is below the limit temperature in can be essentially unyielding or rigid.
- Such a temperature switch is from DE 196 27 969 known. He has one as a force translation or force translator Power transmission element serving rocker arm, the from an expansion box of a thermo-hydraulic expansion system via an intermediate buffer element is pressed and which acts on the snap switch.
- the Buffer element consists of a closed box that is made of two pot-shaped, overlapping halves, between which a compression spring is biased.
- the buffer element transmits the switching force of the expansion socket in the Force range in which the snap spring actuation takes place completely rigid while going beyond one overload becomes compliant and telescopes.
- a metallic can half of the three-part Buffer element is firmly attached to the expansion socket.
- the spring is then inserted to generate a preload using the other can part and the can parts are connected to each other by bending claws. At the further assembly will then be on the expansion element attached buffer element placed on the operating lever.
- This system works fine, but is in the Manufacturing, especially during assembly, is quite complex.
- the invention has for its object a temperature switch of the type mentioned at the outset, which is inexpensive is manufacturable and easy to assemble.
- the buffer and the power transmission form a designable as a buffered power transmission unit Unit, i.e. a unit that contains both the Power transmission functions between expansion element and switching spring, as well as the function of the buffer, which below its limit force like a rigid element of Power transmission works, but one above its limit force brings certain flexibility into the power transmission.
- the Invention enables complete, essentially through the load-dependent buffered or damped power transmission unit and the snap mechanism formed as snap mechanism an assembly, for example on a base of the Temperature switch regardless of the expansion system pre-assemble, for further assembly the expansion element comprehensive assembly put on and adjusted if necessary without attachment between the expansion element and snap mechanism must be provided.
- the power transmission has a lever device with at least one lever on the preferably one-sided in the manner of a cutting edge bearing is supported and / or has a lever arm that on the Switching spring, preferably with point contact, acts.
- a lever is a simple power transmission element whose power transmission over the effective Lever lengths can be selected.

- the expansion system includes a schematically indicated one Temperature sensor 3 in the form of an expansion liquid filled tube, which via a capillary tube 4 with an expansion element in the form of an expansion box 5 connected is.
- the expansion box consists of two bowl-shaped, corrugated sheet membranes attached to their in the figure edges bent upwards by welding or soldering are connected to each other in a pressure-tight manner.
- About one in the Shell of the expansion socket in a centrally arranged connection nipple 6 is the capillary tube 4 with the inside of the between the corrugated sheet metal shells formed cavity.
- nipple 6 On the top of the nipple 6 is integral with the nipple Retaining pin 7 provided in a hollow setting shaft 8 is. This has an external thread 9 with an internal thread cooperates, which is provided in a sleeve 10 is that in the top 12 of a box-shaped Metal housing 13 is integrally formed with this.
- the Adjustment shaft 8 is flattened on one side by an adjustment button non-rotatably. There is an adjusting screw in it 14 provided on the retaining bolt 7 to its vertical Acts adjustment.
- the housing 13 is made of sheet metal and has the shape of a rectangular, partly openwork box whose top 12 mounting brackets 15 for installing the Temperature controller are formed.
- the bottom of the case will of a base part or base 16 made of temperature-resistant, dimensionally stable and electrically insulating material, for example Steatite or other ceramic material, educated.
- the housing 13 is by twisting tabs 17 set.
- the plate-shaped base part 16 carries a snap switch 20.
- This has a switching spring 21 on a switching spring carrier 22 is attached.
- the switch spring carrier 22 is a relatively small, solid sheet metal part, which is a switch tongue abutment 23 in the form of an upward bend having.
- the switch-off position is at the front end of the switch spring one formed from the base part and forming a counter bearing Projection 26 on.
- the switch is in the on position Contact 25 on a counter contact 27, which is on a Mating contact bridge 28 is located under one by the spring provided contact pressure.
- the snap switch carrier 22 and the mating contact bridge 28 create fastening lugs by U-shaped design on the one hand as twisting tabs 29 and on the other hand as well flat tabs fixed by twisting 19 are formed, via which the electrical connection the underside of the plate-shaped base part.

- the lever device 30 comprises a buffered or damped rocker switch 31, the structure of which is related Figures 2 to 4 is explained in more detail. Your is a ceramic Insulated button 32 assigned to the top of the rocker switch is attached and is spherical with its upward curved top 33 in the middle of the large flat Underside 34 on the underside of the expansion socket 5 attached metal disc 35 on a small punctiform Supports the contact point.
- the rigid and electric insulating material of the on a vertically protruding fastening tab 36 of the rocker switch 31 attached ceramic Knob 32 ensures a rigid transmission of the Vertical movement of the bottom of the can onto the rocker switch 31 and creates the necessary electrical insulation between live parts of the snap mechanism 20, 30 and Expansion unit 5.
- the upward curved edges of the Expansion boxes also promote adequate compliance electrical distances between the snap mechanism and the expansion system. That through the flat underside of the metal disc 35 large, flat contact surface provided for the curved top of the insulating piece 32 ensures that the pressure ratios and thus the switching accuracy of the Regulator essentially independent of small position tolerances the expansion unit.
- the switching rocker designed as a one-piece spring steel bent part 31 combines several functions within the Power transmission and overpressure protection, it includes one essentially L-shaped, as a transmission transmission lever acting lever section 40 and one piece with this trained, acting as a buffer U-shaped curved Bow spring 41, the legs 42, 43 in the opening direction the bow spring are biased and the stop is limited up to a predetermined maximum vertical dimension can open. So it is a one-piece rocker switch with integrated overload damper.
- the lever or lever section 40 has to create clearer Pressure ratios with a central, bead-shaped Expression 45 provided lever arm 46 with which he punctiform on an actuation point 47 on a cross extending bead of the switching spring acts.
- lever arm 46 On the opposite End of the lever, which is wider than long, are with large lateral distance from each other two at right angles provided below bent support legs 48, 49, the form lower ends of the cutting edge bearing 50 by being on the Surface of the base part 16 are supported.

- the bow spring 41 has one in the opening direction of its legs Preload that is certainly greater than the limit force, those in the area of the tab 36 or the projections 57, 58 essentially perpendicular to the leg longitudinal direction attacks when the actuating force of the switching spring on their Switching point is reached.
- This interpretation of the spring strength causes the bow spring 41 under pressure from the Expansion box 5 at least as long as a rigid power transmission element acts until the switching point of the switching spring overcome and the contact 25, 27 is open.
- additional forces on the bow spring legs can in contrast cause a compression of the legs, so that in Force flow between expansion element 5 and switch spring one reversible compliance against overpressure given is.
- the assembly of a temperature controller according to the invention is particularly simple, since for snapping the snap mechanism 20, 30 on the base part 16 only simple plugging and bending processes must be made and the connection of the Snap mechanism with the expansion unit 5 only through simple system contact between the large flat Bottom 34 of the metal disc 35 and the dome-shaped Top 33 of the insulating button 32 is created. Even at small lateral position inaccuracies of the expansion unit the switching conditions change relative to the power transmission practically not.
- the complete snap mechanism can be used as an assembly on the base base 16 pre-assembled.
- the parts of the Snap switch on the base part 16 by plugging in corresponding slots and twisting of the tabs 19 and the twist tabs 17, 29 set.
- the one piece Bent sheet metal part very easy-to-use rocker switch 31 is pressed from above over the snap switch carrier and engages due to a snap lock formed by the lugs 51 there one.
- the insulating button 32 can be before or after the installation of the rocker switch on the mounting bracket 36 be placed, with a fastening against lifting off the tab 36 is not necessary because in the assembled Condition and operation of the assembled switch Button 32 is only subjected to pressure.
- the filled and soldered component sensor / capillary tube / expansion socket 5 is attached to the retaining bolt 7. It can use standardized expansion elements or diastats be used as the expansion unit, except for the Need a pressure surface for the insulator 32 provide, not structurally adapted to the snap mechanism must become.
- the adjustment is made using the adjustment screw 14.
- the setting shaft 8 for setting a certain temperature rotated so that the thread 9, 10th the expansion box 5 in a certain position along the Axis 60 of the adjusting shaft is brought.
- the switching spring 21 is already more or less biased and more or less close to their switching point brought up.
- the temperature sensor 3 When the temperature sensor 3 is warmed up, it expands Expansion fluid contained in the sensor and expands the Expansion box 5, so that the metal disc 35 after moves down and the lever 46 counter to that by the switching spring applied force pivoted clockwise.
- the switching spring is supported in such a way that unloaded state of the switching spring the outer end with the Contact 25 is present on counter contact 27, i.e. the switch closed is.
- the one connected via the tabs Circuit is closed via the snap spring and the Switch is on.
- the base part 16 or the switch spring support 22 may have recesses have, in which the tabs 55, 56 can dip, unless the surface level of the base part is constructive should already be deep enough.
- the maximum press-over distance the bow spring can by the height of the frame opening in the Tab be limited. This required amount in turn will of the maximum expansion or the maximum stroke of the Membrane predetermined.
- the expansion box 5 contracts and the strap spring 41, which acts as a buffer, returns to the Figures 1 to 3 shown initial shape with a defined maximum Opening width of the legs elastic back.
- the buffer-lever unit created by the one-piece rocker switch 31 from shift lever 40 and buffer 41 is therefore one absolutely pressure-rigid in the operating state and only when overloaded yielding, but then exactly in his original form moving back one Power transmission between expansion socket and snap switch.
- the spring elasticity in this buffer only becomes effective if the switching has already taken place and is only for Overload protection primarily of the switching spring, but if necessary also the rocker switch itself and the expansion unit.
- the embodiment of a temperature switch shown in FIG. 5 65 is distinguished from that shown in FIG. 1 Embodiment by a particularly low height.
- a flatter, electrically insulating ceramic body 69 provided that when the temperature switch is assembled with its domed top in punctiform pressure contact with a flat underside a metal disc 70 stands on the underside of a Flat membrane expansion socket 71 is present.
- plate-shaped expansion box 5 according to FIG. 1 does that Capillary tube in the radial direction in the plane of the flat membrane directly into the inside of the corrugated, flat sheet metal halves the expansion box 71.
- one Temperature controller 75 differs from those before described embodiments essentially by the Shape of the one-piece rocker switch of the buffer-lever unit and by attaching the electrical insulation between Snap mechanism and expansion unit, you will the example an expansion unit with the edge bent upwards, Similar to Fig. 1 described, but it can also be a flat membrane can be used according to the type of membrane in Fig. 5.
- the rocker switch 76 has the leg length essentially unchanged the bow spring compared to the ones previously described Embodiments of the U-bend 77 extended lever section 78, so that the cutting edge bearing 79 Support legs 80, 81 away from the adjustment axis 82 into the Area of the U-bend. In the area of the adjustment axis is one instead of the retaining tab for the insulating piece Dome-shaped upward expression 83 of the upper Bow leg trained.
- the shift paddle from the expansion unit 84 is electrical insulating insulating piece 85 is not on the rocker switch attached, but is of a cross section of FIG. 7 easily recognizable bow spring 86 worn, the free Thighs on opposite, outwardly protruding Support the horizontal beads 87, 88 of the housing 89.
- the Insulator 85 has a flat bottom surface 89 with which it is supported point-by-point on the calotte 83 of the rocker switch, and an axial blind hole opening 90, in which is a bolt-shaped, vertical neck 91 on the underside the expansion unit 84 is inserted with a precise fit.
- the insulating button 85 is thus by means of a resilient sheet metal part 86 axially pressed against the membrane 84 and is by its movable attachment to the housing part of the assembly assembly "Casing". If the bow spring together with the insulating piece in inserted the housing and subsequently also the expansion unit is installed, then one can by the bow spring 86th provided, upward axial preload any axial play in the area of the adjustment unit eliminate what can increase the setting accuracy.
