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, the temperature changes its geometric shape between a closed and an open position and in its closed position the current flowing through the switch leads, and includes an actuator which is permanently connected electrically and mechanically in series with the switching element.
  • Such a switch is from the US 4,636,766 A as well as out US 5,196,820 known.
  • the known 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.
  • Another, from the EP 0 103 792 B1 known, current-dependent switch has as a switching member 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, which is arranged at the free end of an elongated spring element, 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.
  • bimetal disc is fixed to the free end of a spring element, wherein the connection point between the spring element and bimetal disc is supported by a housing-fixed nose. In this way, the bimetal disc is under mechanical bias, which suppresses the creep phase.
  • the bimetallic switching mechanism comprises a mating contact mounted on a spring arm and a movable contact part mounted on a bimetallic arm.
  • the bimetallic arm is either attached directly to the lower housing part or it is supported by a further bimetallic arm, which in turn is attached to the lower housing part.
  • the bimetal is provided with an embossment for adjusting the defined snap point, wherein either the bimetallic arm itself or the other bimetallic arm is associated with an abutment about which pivots the corresponding bimetallic arm with temperature changes.
  • the bimetallic arms must be additionally provided with the creep-limiting imprints, and also support approximately centrally on a counter-bearing, around which they bend accordingly.
  • the derailleur comprises a spring washer which is supported in the closed state of the switch with its edge on a first terminal electrode and a centrally supported movable contact presses against a stationary counter-contact, which is provided at a second terminal electrode.
  • the two terminal electrodes form in the known switch an encapsulated metallic housing and are electrically isolated from each other by an insulating.
  • a bimetallic snap disk is slipped, which is below its switching temperature loosely inside the known switch, so is exposed to no mechanical stress.
  • the operating current of the device to be protected in this switch flows only through the spring washer, the bimetallic snap disk is not loaded by the operating current.
  • the switching element comprises a spring element whose force is largely independent of temperature
  • the switching member has a temperature-dependent actuating force which is greater than the restoring force of the spring element in its creep phase, regardless of its geometry change in the creep phase, the switching element compared to the spring element is to be regarded as rigid, so that the contact pressure is exerted solely by the force of the spring element.
  • the object underlying the invention is completely solved in this way.
  • the inventor of the present application has namely recognized that the from the DE 21 21 802 C known mechanical and electrical parallel arrangement of temperature-neutral spring element and switching element in an electrical and modified mechanical series circuit and can be used in the generic switch to unite a number of advantages in the thus created new switch.
  • 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 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 is only one Bimetallic element required, the spring element is temperature-neutral and therefore inexpensive. Overall, bimetallic element and spring element must still be matched with respect to the rest of the force, but no longer also in terms of their temperature behavior, because the rear derailleur is, so to speak, self-sufficient. As a result, a standard spring element for all temperature ranges is possible, whereby a significant rationalization effect is achieved. 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 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 member carries at its free end a movable contact part, which cooperates with the mating contact.
  • the switching element and the spring element welded together or are firmly connected by crimping, preferably wherein 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.
  • a further advantage of this construction is overall in the small space requirements, by the "folded back" arrangement of the mating contact with respect to the connection between the switching element and spring element are on the one hand small dimensions in the longitudinal direction required. But also transversely to the longitudinal direction, ie in "switching direction", only small dimensions are required.
  • the switching member tends to lift the movable contact part of the mating contact, which is compensated by lowering the connection point between the spring element and switching element.
  • the switch now snaps over, the joint moves even further towards the mating contact, while simultaneously moving the movable contact in the opposite direction.
  • the path between the attachment point of the spring element to the first outer terminal and the mating contact is thus used twice, once 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 ,
  • first and the second terminal electrode are held by a Isolierstoff uman, wherein Preferably, the second terminal electrode is an integral part of an insulating housing lower part by encapsulation, which is closed by the first terminal electrode.
  • This measure is structurally of great advantage, because the four basic components of the new switch, namely switching element, spring element and the two terminal electrodes can be assembled into a so-called open as well as a closed switch, without the construction of the four components themselves must be changed.
  • the cover part formed by the first terminal electrode and the bottom part formed by the second terminal electrode may be planar, planar electrodes, which was not previously possible in the prior art.
  • this not only leads to a very low height of the new switch, these flat surfaces also create a prerequisite for Substratbedruckung to realize pre- or parallel resistors can be given to the new switch more functions.

  • the Isolierstoffong 16 can basically be open on the side, is in Fig. 1 an embodiment shown in which the Isolierstoff relie 16 comprises a cup-shaped housing lower part 17 which is formed around the second terminal electrode 15 around by molding or casting such that the second terminal electrode 15 is an integral part of the housing lower part 17.
  • the lower housing part 17 is closed by the first terminal electrode 12, which acts for this purpose as a cover part and is held captive by a indicated at 18, hot-welded edge of the insulating substrate 16.

  • 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 switching element 22 moves into its opening position, which will be described later, 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 a self-holding the once opened switch 10th
  • Fig. 2 is a top view of the switch off Fig. 1 shown here, in which case the first and the second external terminal 11, 14 not as in Fig. 1 among themselves but adjacent to each other are indicated.

  • FIG. 3 another switch 10 is shown which does not have the square outline Fig. 2 but has a round outline. Otherwise, the switch 10 corresponds Fig. 3 however, the construction as he is in Fig. 1 shown in longitudinal section, wherein the same design features are denoted by the same reference numerals.

For this purpose, first the connection 23 by welding ( Fig. 1 ) or flanging ( FIGS. 4 to 6 ), whereupon the spring element 21 is then welded at its first end 25 to the connection electrode 12. Due to the V-shaped design of the switching mechanism thereby comes the free end 27 of the switching member 22 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.

However, the force of the bimetallic element is still so great that the force of the spring element 21 is not sufficient to hinder the deformations occurring in the creep phase.
