Definitions

  • the present invention relates to a switch with a Isolierstoffong, on which a first and a second external connection are arranged, as well as a temperature-dependent Rear derailleur that depending on its temperature between an electrically conductive the first and the second external connection Connection for one to be passed through the switch produces electrical current, and a switching device that its geometric shape depending on the temperature between a closing and changed an open position and in its closed position the current leads, and includes an actuator that with the Switching element is electrically and mechanically connected in series.
  • the known switch comprises a U-shaped bimetal element as a switching element with two legs of different lengths. On a movable contact part is attached to the long leg, that interacts with a switch-fixed counter contact that again with one of the two external connections in electrical conductive connection.
  • the shorter leg of the U-shaped bimetal element is on the free end of an actuator designed as a lever arm attached that with its other end firmly to the housing is connected as well as with the other of the two external connections is in an electrically conductive connection.
  • the actuator is another bimetallic element that is so on the U-shaped bimetallic element is agreed that the two bimetallic elements deform in opposite directions with temperature changes and thus the contact pressure between the movable contact part and the counter contact fixed to the housing.
  • This switch is intended as a breaker for high currents, which leads to a strong warming of the bimetallic elements lead, which ultimately the movable contact part is lifted off the fixed counter contact. Influences of Ambient temperature are the opposite Deformation of the bimetallic elements is compensated.
  • the two bimetal elements are very different geometrically are designed, they also have different long-term stabilities on, so that from time to time a readjustment would be required. However, this is not in use more possible, so that overall long-term stability and thus the functional reliability leaves something to be desired.
  • Another disadvantage of this construction is that large height due to the U-shaped bimetal element.
  • this switch has the disadvantage that it closes again automatically after cooling, i.e. none Has self-holding function, the reclosing and thus Switch on the electrical protected by the switch Device prevented.
  • Switches with self-holding function are generally known at They are switched in parallel to the temperature-dependent switching mechanism Self-holding resistor connected between the two external connections. When the switch is closed, the Self-holding resistor electrically short-circuited by the switching mechanism, so that it is de-energized. On the other hand, opens the rear derailleur, a residual current flows through the self-holding resistor depending on the applied voltage as well its resistance value heats up so far that it is temperature-dependent Switch mechanism at a temperature above the response temperature stops so that it stays open.
  • Another current-dependent one known from EP 0 103 792 B1 Switch has a bimetal spring tongue as a switching element on, which is attached to the one external connection and to her free end carries a movable contact part that with a Counter-contact cooperates, which at the free end of an elongated Spring element is arranged, the other end on the other external connector is attached so that the current through the Series connection from spring element and bimetal spring tongue flows.
  • the elastic mounting of the counter contact ensures a low mechanical stress on the bimetal spring tongue, because of the Mating contact yields to a limited extent when the bimetal spring tongue changed their geometric shape due to a change in temperature. This causes irreversible deformations of the bimetal spring tongue avoided, leading to a shift in the switching temperature could lead.
  • a disadvantage of this switch is that the bimetal spring tongue like all bimetal elements in the transition from In the open position, a so-called creep phase passes through, in the course of a temperature increase or lowers the bimetallic element creepingly deformed without however from its e.g. convex low temperature position already to snap into its concave high temperature position.
  • This Creeping phase occurs every time the temperature changes of the bimetal element either from above or from below Jump temperature approaches and leads to noticeable changes in conformation. Especially as a result of aging or long-term use can the creep behavior of a bimetallic element furthermore also change.
  • sneaking can cause that the pressure of the contact against the counter contact decreases, which creates undefined switching states.
  • the closing movement can make contact during the creeping phase gradually approach the counter contact, reducing the risk of Arc can be caused.
  • this task is accomplished solved that the first external connection with a flat cover electrode is connected to the actuator with its first End is set, and on the inside a flat Self-holding resistor is arranged, the electrically between the cover electrode and the second external connection are switched is.
  • the inventor of the present application has recognized that that it is possible when using a flat cover electrode is a flat self-holding resistance on the inside to be arranged without noticeably influencing the overall height. in the In contrast to a block-shaped PTC element, such a e.g. Sheet resistance namely such a small thickness, that this leads to a hardly noticeable increase in the thickness of the Cover electrode leads.
  • the actuator is a Includes spring element, the actuating force largely independent of temperature is, and the actuator is a temperature-dependent Has actuating force that is greater than in its creeping phase the force of the spring element.
  • the inventor of the present application has recognized that the e.g. known from DE 21 21 802 C mechanical and electrical parallel arrangement of temperature-neutral spring element and switching element in an electrical and mechanical series connection modified and used in the new switch can be a number of other advantages in the unite new switch.
  • the temperature-neutral spring element exercises on the bimetal element no longer hinder its deformation, it rather resembles the deformation of the bimetal element in the creeping phase through its own deformation in such a way that movable Contact part and fixed counter contact with each other in such a way stay safely in the system for a low contact resistance is taken care of.
  • the contact pressure remains below the Switching temperature largely independent of the temperature.
  • the creeping phase of the bimetallic element is therefore no longer as suppressed in the prior art, but balanced so to speak, the bimetal element can namely in the Deform creep phase almost unhindered, making the changes the geometry is balanced by the spring element that the switch remains securely closed.
  • the temperature-dependent positioning force of the bimetal element chosen so that they are larger in the creeping phase is the largely temperature-neutral actuating force of the Spring element, which is thus the "rigid" bimetal element only "leads".
  • a big advantage of the new switch is its simple Construction, in addition to a housing-fixed counter contact is only a bimetal element is required, the spring element is temperature neutral and therefore inexpensive. Overall, bimetal element and spring element to each other with respect to the actuating force be coordinated, but no longer additionally regarding their temperature behavior, because the rear derailleur straightens yourself, so to speak. This makes it a standard spring element possible for all temperature ranges, making an essential one Rationalization effect is achieved. Through this construction a low overall height can also be realized, whereby at different switching temperatures no new individual Adjustment is required, just the bimetal element must have the same spring properties but different switching temperatures be interpreted.
  • Another advantage is that tolerances and fluctuations in the switching temperature by guiding through the temperature-neutral Spring element to be balanced.
  • the second external connection is connected to a bottom electrode with which a Movable contact part cooperates that on the switching element is provided, and between the lid electrode and the bottom electrode a connecting element is arranged, the Self-holding resistor connects to the bottom electrode.
  • the connecting element can either be installed as a separate part in the assembly Switches are inserted, or beforehand on the lid electrode or the bottom electrode. Complicated Solder connections or electrical wire connections are thus not required for contacting the self-holding resistor.
  • a flat series resistor is arranged which electrically between the first outer terminal and the first end of the spring element is switched.
  • an insulation layer is arranged on the at least one resistance track is arranged, one end with the first external connection and the other end with a contact surface is connected to a contact surface of the connecting element or in contact with the spring element.
  • the connecting element is one the contact plate on the insulating material carrier, which is connected to the Contact surface is in contact, as well as pointing to the bottom electrode Has contact bracket, which between them one of the Clamp the upright tab on the base electrode.
  • the spring element is on its first end is T-shaped, with this T-shaped End rests on the insulating material carrier and on this T-shaped end has a contact surface that is in contact with the contact surface of the series resistance is in the system.
  • the spring element and the switching element are essentially flat, sheet-like parts that are extend to the same side in a V-shape from their connection point.
  • This measure has the advantage that compared to the generic switch, the overall height is significantly reduced, and also a slight longitudinal extension because of the "folded back" free end of the switching element reached becomes.

  • the switching element 22 is a bimetal element in the present case.
  • the spring element 21 has a largely temperature-independent Actuating force, what in the context of the present invention means that the force or spring force of the spring element 21 in the range of the permissible operating temperature of the Switch 10 does not change noticeably.
  • the positioning force of the bimetal element is strongly temperature dependent and also in the so-called creeping phase is so large that the spring element 21 do not hinder the deformation of the bimetallic element Pressure on that at constant temperature in this spring system thus can exert rigid bimetal element.
