Definitions

  • the invention relates to an adjusting device for a thermal release of a switching device according to the preamble of claim 1.
  • Such an adjusting device is known from EP 0 913 848 A2.
  • Such a switching device is used to connect a circuit to a power grid and for manual and automatic disconnection of the circuit from the network when the current exceeds a predetermined value.
  • a miniature circuit breaker protects cables in installations and systems against overload and short circuits. In a network with shutdown by overcurrent protective devices prevents such a switching device in case of failure in addition to the persistence of high contact voltages.
  • the switching device or circuit breaker is a power storage, eg. As a spring, as part of a mechanical switching mechanism or switching mechanism clamped, which is released during the tripping operation and actuates the switch.
  • the switching device comprises a thermal release in the form of a usually strip-shaped bimetal, which triggers delay-dependent delayed overload. The tripping operation is triggered by a thermal deformation of the bimetallic strip as a result of the overcurrent carried over this.
  • the bimetallic strip acts on a release lever spaced opposite its free end and mechanically coupled to the switch lock.
  • the switching mechanism With unlatched about this the bimetallic strip the switching mechanism, while the energy storage of the switching mechanism opens a movable contact or moving contact by this lifts from a fixed contact.
  • the switching device usually also includes an instantaneous triggering magnetic or electromagnetic trigger for high surge and short circuit currents.
  • the distance between the free end of the bimetal and the release lever is adjustable, what an adjusting screw is usually provided for.
  • Switching devices in which such an adjusting screw are used for bimetallic adjustment are known, for example, from DE 1 904 731 A1 and from EP 0 143 981 A1, EP 0 412 953 A3, from EP 0 338 868 A1.
  • the use of an adjusting screw is associated with corresponding manufacturing and manufacturing costs.
  • the invention is therefore based on the object, a particularly inexpensive and easy to handle adjusting device for a switching device, in particular for a circuit breaker specify.
  • the bimetal has a parallel to the bimetal and connected to the contact end holding leg with a fixation as a fixed attachment point.
  • step-shaped curved holding leg closes on the one hand an effective as an adjustment range handling leg and on the other hand via a bend at least approximately U-shaped fixing leg of the bimetallic carrier.
  • the step contour of the retaining leg allows the holder of different lengths, in particular also indirectly heated bimetals by means of the same bimetal. As a result, the number of different thermal releases that need to be provided or kept available for different types of switching devices, can be significantly reduced and kept very low overall.
  • the handling leg is advantageously designed like a perforated plate.
  • a number of through holes preferably in the form of round holes are introduced into the handling leg.
  • the handling leg of the bimetallic carrier may be fixed in position in a stationary housing opening or contour which is also effective as a rotary opening.
  • the handling leg is expediently positioned in the region of the free end of the bimetal.
  • the bimetallic support may be formed like a loop, wherein the handling leg is then supported on the front side of the bimetallic support.
  • a predetermined bending point is preferably formed in the region of the loop vertex of the bimetal carrier.
  • the switching device has a housing which is formed from urea and / or melamine resin molding compound.
  • the urea or melamine resins belonging to the family of thermosetting plastics are particularly suitable for a cost-reducing production of mass and series products.
  • the advantages achieved by the invention are, in particular, that this is deliberately deformed by suitable design and arrangement of a bimetallic carrier carrying the bimetal and thus a simple and inexpensive, possibly automatically adjusting adjusting device for a thermal release of a switching device can be provided.
  • the distance of the free end of the bimetal to the release lever is on the one hand by deformation, especially by means of a tool of handling or holding leg adjustable or adjustable, or on the other hand by automatic bending of the bimetallic strip in an age-related GeHousenachschwindung be maintained.
  • FIGS 1 to 4 show a detail of a switching device 1 with the housing cover lifted off the housing 2, in which the essential parts of an adjustable thermal release are shown visible.
  • the thermal release comprises a bimetallic strip 3, whose contact end 3a is integrally connected to a bimetallic support 4 and thus held stationary.
  • the bimetal 4 is electrically connected to a terminal 5 for power management via the switching device 1.
  • the free end 3b of the bimetal 3, that is, the bimetal, is a trigger lever 6 spaced opposite, which is coupled to a non-illustrated rear derailleur or switch lock in a conventional manner.
  • This distance A between the bimetallic tip 3b and the release lever 6 is adjustable by bending or deformation of the bimetal 4.
  • the bimetallic support 4 is bent or bent several times and additionally shaped like a step.
  • a bimetal 3 with its contact end 3a can be fixed at each stage S1, S2 and thus at different positions or connection points of the bimetallic support 4.
  • both a short bimetal 3 according to Figures 1 and 2 and a comparatively long bimetal 3 according to Figures 3 and 4, which can be designed to be heated indirectly, on the same bimetallic 3 can be fixed or attached.
  • the bimetal beam 4 has a handling leg 4a and a transverse thereto, i. at least approximately at right angles extending holding leg 4b. With this holding leg 4b, the contact end 3a of the bimetal 3 is firmly bonded.
  • the holding leg 4b merges at a bending point 8 into a fixing leg 4c, which itself is bent approximately in a U-shape.
  • this fixing leg 4c of the bimetallic support 4 is fixed in position in the housing 2 by corresponding housing structures or - contours 9 and clamped by means of a terminal screw 11.
  • the holding leg 4b is at least part of the leg length without installation in the housing 2 a.
  • beads 12 are introduced into the holding limb 4b, so that a relatively thin sheet material for the bimetallic support 4 can be used with high dimensional stability and sufficient support rigidity.
  • the handling leg 4a of the bimetal carrier 4 which is located in the region of the free end 3b of the bimetal 3 and is directed outwards there, is held on the end face in a housing opening or contour 13 and is supported there.
  • the handling leg 4a is formed deformable. This is the bimetallic adjustment and thus for adjusting the distance A between the free end 3b of the bimetal 3 and the release lever 6 by means of a (not shown) handling tool of the handling leg 4a of the bimetallic support 4 twisted and thus the bimetal 4 bent or deformed. As a result, the position of the bimetal 3 for adjusting the distance A changes accordingly.
  • the adjusting device is essentially formed by the position-fixed handling leg 4b of the bimetallic support 4 with the bimetal 3 held thereon.
  • FIGS. 5a to 5d show different geometries of the handling leg 4a of the bimetal carrier 4. While this T-shaped handling leg 4a according to FIG. 5c can in principle be formed from solid material, passage openings 23 in the handling leg 4a and thus in the adjustment region are expediently along the leg longitudinal axis 14 of the bimetal carrier 4 introduced. These passage openings 23 may be designed as elongated holes or as rectangular openings according to FIGS. 5b and 5d. However, a number of circular bores 23 according to FIG. 5a are advantageous. In fact, with this geometry, a particularly favorable ratio between the angle of rotation and the change in length of the handling leg 4a can be realized. As a result, the desired goal is achieved to a particularly high degree to allow for a relatively large angle of rotation and a small change in length, a sensitive and accurate adjustment.
  • the handling leg 4a In the embodiment of the adjusting device according to Figures 6 and 7 of the handling leg 4a is provided with a nose-like contour 15, which can be guided along an arcuate housing and thus fixed counter contour 16.
  • the adjustment and thus the adjustment of the distance A takes place by bending the handling leg 4a in the direction of the arrow 17.
  • the handling leg 4a moves as it slides along the nose-like contour 15 along the arcuate stationary counter contour 16 in the direction of arrow 18, so that the bimetallic tip 3b in turn moves in the triggering direction D.
  • the length of the symbolized by the arrow 17 movement path of the handling leg 4a depends on the slope of the arcuate stationary counter contour 16.
  • the handling leg 4a is in turn bent inwards and in turn is bent to form a first bending / bending point 19 '.
  • the buckling / bending point 19 ' is - as well as the bending point 8 - formed by a hole or punching in the sheet material of the bimetal 4.
  • the handling leg 4a is guided in a housing receptacle or rotary opening 20 which is effective as a rotary contour and which is provided in a suitably positioned housing contour in the form of a dome-shaped housing structure 21. At this lying within the rotational opening 20 free end of the handling leg 4a engages the actuating tool for Bimetalljust réelle.
  • the bimetallic support 4 is in turn bent or deformed and changed the position of the bimetal 3 for adjusting the distance A.
  • a roll-up-like rotation of the handling leg 4a takes place around an axis running perpendicular to the plane of the drawing.
  • the handling leg 4a is twisted about its leg transverse axis.
  • a fork-shaped twisting or handling tool 24 is twisted or twisted, which is used for this purpose in the rotation or adjustment hole 20 and rotated in the direction of arrow 22.
  • the bimetal tip or the free end 3b of the bimetal 3 is rotated in the triggering direction D, thereby performing the bimetallic adjustment.
  • the adjusting device is essentially formed by the bimetallic support 4 with the bimetal 3 held thereon and the rotary opening 20 in the housing attachment 21 which acts as an adjustment contour.
  • the bimetal 3 is adjusted by a kind of bending buckling of the handling leg 4a of the bimetallic support 4 in the direction of the deformation arrow 22 '.
  • the free end 4a 'of the handling leg 4a is held in a housing opening 20', so that in the central region 4a '' of the handling leg 4a this can be buckled or folded.
  • the bimetallic point or the free end 3b of the bimetal 3 in the release direction D moved and thereby performed the bimetallic adjustment.
  • FIG. 11 shows an alternative embodiment in which the holding leg 4b of the bimetal carrier 4 is guided around a housing contour 25 to form a loop.
  • a predetermined bending point 27 is introduced into this.
  • the handling leg 4a is located on the front side in the transition region between the holding leg 4b and the fixing leg 4c and thereby in the vicinity of the bending point 8 of the bimetallic support 4 and is supported there.
  • the bimetallic tip or the free end 3b of the bimetal 3 is in turn rotated in the triggering direction D, thereby carrying out the bimetallic adjustment.
  • Figures 12 and 13 show an alternative embodiment of the thermal release, which differs on the one hand from the embodiment of the thermal release according to Figures 1 and 2 by the use of a setting means 28 in the form of an adjusting screw or alternatively in the form of a stepwise latching pin or the like ,
  • the adjustment by the adjusting means 28 handling leg 4a is arranged largely perpendicular to this.

  • beads 12 are likewise introduced into the holding limb 4b in the region of the steps S1 and S2, so that a relatively thin sheet material for the bimetal carrier 4 can be used with high dimensional stability and sufficient carrier rigidity.
  • Corner beads 12 and bending / bending / bending points 8 or 19 ', 19' 'provided with bores / punched-out portions 29 can accordingly vary depending on the desired mode of operation, such as e.g. a partial stiffening or an automatic readjustment in the form of a buckling at predetermined bending points, the bimetal 4 are introduced specifically.
