Definitions

  • the present invention relates to a switch having a first and at least one second external terminal and a temperature-dependent switching mechanism, which produces an electrically conductive connection for an electrical current to be conducted through the switch as a function of its temperature between the two external terminals, wherein the switching mechanism is a switching element, which varies its geometric shape depending on temperature between a closed and an open position and in its closed position leads the current flowing through the switch, a spring element which is permanently connected electrically and mechanically in series with the switching element, and comprises a security element in the form of a compression spring, which, when a safety temperature is exceeded for the first time, keeps the switch open regardless of its further temperature.
  • the switching mechanism is a switching element, which varies its geometric shape depending on temperature between a closed and an open position and in its closed position leads the current flowing through the switch, a spring element which is permanently connected electrically and mechanically in series with the switching element, and comprises a security element in the form of a compression spring, which, when a safety temperature is exceeded for the first time, keeps the switch
  • the known switch carries a bimetallic element at its free end a movable contact which cooperates with a fixed counter-contact. At its other end, the bimetallic element is connected to a spring element which sits at its free end on a bolt, where it is held over fusible link. On the bolt also sits a security element in the form of a compression spring, which is an end to the Supporting portion of the spring element and other end supported on a bottom of the known switch.
  • the current flows through the known switch via the bolt, the spring element, the bimetallic element, the movable contact and the fixed mating contact.
  • This circuit is opened below the safety temperature, characterized in that the bimetallic element lifts the movable contact when its response temperature is exceeded by the fixed mating contact.
  • the fusible link ensures an electrically conductive connection between the bolt and the spring element.
  • the fusible link is exposed to permanent loads, which is considered disadvantageous.
  • a switch comprises as a switching element, a U-shaped bimetallic element with two legs of different lengths. On the long leg, a movable contact member is fixed, which cooperates with a switch-fixed mating contact, which in turn is in an electrically conductive connection with one of the two outer terminals.
  • the shorter leg of the U-shaped bimetallic element is attached to the free end of a lever arm formed as an actuator, which is connected at its other end fixed to the housing and is in electrically conductive communication with the other of the two outer terminals.
  • the actuator is another bimetallic element, which is tuned to the U-shaped bimetallic element, which deform the two bimetallic elements in opposite directions with temperature changes and thus maintain the contact pressure between the movable contact part and the housing-fixed mating contact.
  • This switch is intended as a breaker for high currents, which lead to a strong heating of the flowed through bimetal elements, whereby ultimately the movable contact part is lifted from the fixed counter-contact. Influences of the ambient temperature are compensated by the aforementioned opposing deformation of the bimetallic elements.
  • the two bimetallic elements are designed geometrically very different, they also have different long-term stabilities, so that actually from time to time a readjustment would be required. However, this is no longer possible in use, so that overall the long-term stability and thus the functional reliability leaves something to be desired.
  • FIG. 1 Another, known from EP 0 103 792 B1, current-dependent switch has as a switching element on a bimetallic spring tongue, which is attached to the one outer terminal and carries at its free end a movable contact part, which cooperates with a mating contact on the free End of an elongate spring element is arranged, the other end is attached to the other external terminal.
  • the switch is connected with its external terminals in series with an electrical device, that the operating current of this switch flows through the bimetallic spring tongue.
  • the well-known Switch further thermally coupled to the electrical device so that it can follow the temperature changes.
  • the bimetallic spring tongue lifts the moving contact away from the mating contact, interrupting the flow of current and protecting the electrical device against further heating. In this open position, however, the bimetal spring tongue can also be brought by an increased current flow, since the bimetallic spring tongue heats up through the electrical current flowing therethrough.
  • the electrical properties of the bimetal spring tongue can now be adjusted in coordination with the mechanical properties and the transition temperature so that it is in its closed position in which it directs the operating current of the electrical device when both the ambient temperature is below the switching temperature as well the operating current is below a response current. Now increases the operating current beyond the permissible value, so heats up the bimetal spring tongue very quickly and reaches its critical temperature, whereupon it goes into its open position.
  • This switch provides protection against both over temperature and overcurrent.
  • the elastic Storage of the mating contact further ensures a low mechanical load on the bimetal spring tongue, since the mating contact gives limited. As a result, irreversible deformations of the bimetallic spring tongue are avoided. Since such mechanical deformations can lead to a shift of the switching temperature, this arrangement provides a total of high reliability.
  • the bimetallic spring tongue as all bimetallic elements in the transition from the closed to the open position passes through a so-called creep, in which due to a temperature increase or decrease the bimetallic element deforms creeping, but without its eg Convex low-temperature position already in its concave high-temperature position umzuschnappen.
  • This creep phase occurs whenever the temperature of the bimetallic element approaches either the top or the bottom of the transition temperature and leads to significant conformational changes.
  • the creep behavior of a bimetallic element can also change beyond.
  • the creep can cause the pressure of the contact against the mating contact to decrease, which results in undefined switching states.
  • the contact may be during the slow phase gradually approach the mating contact, which can cause the danger of an arc.
  • the bimetallic snap disk is here attached centrally to an adjusting screw and is pressed by a compression spring against the head of this adjusting screw.
  • This head is attached via fusible link to the adjusting screw itself, which liquefies when exceeding a lying above the response temperature of the bimetallic snap disk safety temperature, whereupon then the compression spring pushes down the bimetallic snap disk of the adjusting screw, whereby the switch is irreversibly opened.
  • this switch has the advantage that engages in overheating due to a high current flow and associated welding of the movable contacts on the fixed mating contacts another security mechanism. After welding namely, the force of the bimetallic snap disk is no longer sufficient to lift the movable contacts of the fixed mating contacts, but the pressure of the compression spring, which counteracts no counterforce after liquefying the fusible link.
  • Another disadvantage is that in order to avoid contact blinking the bimetallic snap disk must be provided with a strong pre-stamping to suppress the creep phase.
  • the electrical series connection of the spring element and switching element results in a current-dependent switch, since the switching element, which is preferably a bimetallic element or a trimetal element, can heat up very quickly due to its low thermal mass at too high current flow or even at short current peaks , Due to the mechanical series connection, so the interaction of the spring force of the spring element with that of the switching element, beyond the creep phase of the switching element can be compensated. If the switching element changes its geometry during the slow phase, this is compensated directly by the spring element. This makes it possible for the first time, even with a so-called current-dependent switch to allow a large creep phase of the switching element, because the spring element can compensate for the "unwanted" changes in shape during the creep phase.
  • the mechanical spring force of the switching device plays in the new switch for the first time in the art a minor role, it must only be so large that the switching element by the spring element not compressed too much.
  • the switching process itself is effected after completion of the creep phase solely by the switching device, which is now always biased in its closed position.
  • This biased switching device still has a whole series of other advantages, so it does not vibrate in the magnetic field and has no risk of arc, because gradually opening or closing contacts are prevented by the bias.
  • the temperature-neutral spring element exerts on the bimetallic element no more hindering its deformation pressure, it is similar in the creep phase, the deformation of the bimetallic element by their own deformation such that movable contact part and fixed mating contact with each other so securely in abutment that for a low contact resistance is ensured, the contact pressure remains below the switching temperature largely independent of the temperature constant.
  • the creep phase of the bimetallic element is therefore no longer suppressed as in the prior art, but balanced, so to speak, the bimetallic element can namely deform almost unhindered in the slow phase, the changes in geometry are compensated by the spring element so that the Switch remains securely closed.
  • the temperature-dependent actuating force of the bimetallic element is chosen so that it is greater than the largely temperature-independent actuating force of the spring element in the creep phase, which thus merely “leads” the thus "rigid” bimetallic element.
  • a big advantage of the new switch is its simple design, in addition to the housing-fixed mating contact only a bimetallic element is required, the spring element is temperature-neutral and therefore inexpensive. Overall, bimetallic element and spring element still have to each other in terms of the force be tuned, but no longer also in terms of their temperature behavior, because the rear derailleur aligns itself, so to speak. By this construction, a low overall height is also feasible, with no new individual adaptation is required at different switching temperatures, only the bimetallic element must be designed with the same spring characteristics but other switching temperatures.
  • Another advantage is that tolerances and fluctuations in the switching temperature are compensated by the leadership by the temperature-neutral spring element.
  • the compression spring which acts according to the invention on the actuator, more preferably the compression spring is arranged functionally between the mating contact and the switching member and further preferably present before first exceeding the safety temperature in compressed position and in this position a fusible link is maintained, which melts upon reaching the safety temperature, so that the compression spring can relax.
  • the spring element is connected at its first end to the first connection element and at its second end to the switching element, wherein preferably by the spring element, the switching element in its closed position with its free end against a connected to the second connection element Counter contact is pressed and lifts in its open position its free end of the mating contact, which is further preferably arranged switch fixed, wherein also preferably the switching element on his free end carries a movable contact part, which cooperates with the mating contact.
  • the free end of the switching element and the first end of the spring element lie on the same side of the connection between the spring element and switching element.
  • the path between the attachment point of the spring element to the first outer terminal and the mating contact is thus used twice, as it were for the compensating movement of the junction between the switching element and spring element during the slow phase of the switching element and the other to lift the movable contact part of the mating contact.
  • the first external terminal is connected to a terminal electrode to which the spring member is fixed at its first end, and when preferably the second external terminal is connected to a second terminal electrode and the switching mechanism is disposed between the first and second terminal electrodes ,
  • a switch is generally shown at 10, which is shown in schematic longitudinal section.
  • the switch 10 has a first external terminal 11, which is integrally connected to a flat terminal electrode 12. Further, a second external terminal 14 is provided, which is formed integrally with a second terminal electrode 15. The two terminal electrodes 12, 15 are held on a Isolierstoffong 16 which holds the two terminal electrodes 12, 15 spaced parallel to each other.
  • the Isolierstoffong 16 can be basically open on the side, an embodiment is shown in Fig. 1, in which the Isolierstoff relie 16 comprises a cup-shaped housing lower part 17 which is formed around the second terminal electrode 15 by encapsulation or casting such that the second terminal electrode 15th integral part of the housing lower part 17 is.

  • a temperature-dependent switching mechanism 19 which comprises a mechanical and electrical series connection of a spring element 21 and a switching member 22 which are interconnected by a connection indicated at 23.
  • the switching member 22 is in this case a bimetallic element.
  • the spring element 21 in this case has a largely temperature-independent actuating force, which means in the context of the present invention that the actuating force or spring force of the spring element 21 does not change appreciably in the range of the permissible operating temperature of the switch 10.
  • the force of the bimetallic element is strongly temperature-dependent and even in the so-called slow phase so great that the spring element 21 can not exert the deformation of the bimetallic element disabling pressure on the constant temperature in this spring system thus rigid bimetallic element.
  • the spring element 21 is fastened with its first end 25 in Fig. 1 right to the first terminal electrode 12 and leads with its second end 26 in the connection 23 to the switching member 22.
  • the switching member 22 carries at its free end 27 a movable contact part 28, which cooperates with a switch-fixed mating contact 29 which is formed on the second terminal electrode 15.
  • a PTC element indicated at 31 is still provided, which is arranged electrically parallel to the switching mechanism 19.
  • the switching mechanism 19 establishes an electrically conductive connection between the two outer terminals 11, 14 and thereby closes the PTC element 31 short.
  • a current flowing through the switch 10 now passes from the first external terminal 11 in the first terminal electrode 12 and from there via the spring element 21 in the switching member 22, from which it exits via the movable contact member 28, via the mating contact 29 and the second terminal electrode 15 to get to the second external terminal 14.
  • the switching element 22 moves into its open position to be described in which it lifts the movable contact part 28 away from the mating contact 29 , As a result, the flow of current through the switching mechanism 19 is interrupted, so that now a residual current can flow through the PTC element 31.
  • This residual current heats the PTC element 31 so far that the temperature in the switch 10 remains above the response temperature of the switching element 22. In other words, the PTC element ensures latching of the once opened switch 10.

  • the free end 27 of the switching element 22 comes about via the mating contact 29 to lie. It should be mentioned that, of course, can be dispensed with the movable contact member 28 that is provided by the contact member 28, however, for a better contact resistance to the mating contact 29.
