Definitions

  • the invention relates to an electrical switching device, in particular a circuit breaker, with a housing formed from two flat shells, with a switching mechanism arranged therein, which is coupled to a manual control handle and a contact lever which assumes two stable switching positions, each switching position of the contact lever being an end position of the manual control handle corresponds.
  • the manual control handle has two end positions, each corresponding to the switch position "ON or” OFF ".
  • the switch position" OFF " can be achieved both by self-triggering and by manual actuation.
  • the problem arises that often not all circuits are switched on and accordingly not all hand controls are in the switched-on position. If there is a fault in a switched-on circuit that automatically triggers the protection provided electrical switching device leads, it is not readily apparent which switching device is switched off due to automatic triggering.
  • the solution to the problem is characterized in that the manual switch assumes an intermediate position when the electrical switching device is triggered automatically, which lies between its end positions corresponding to the switch-on and switch-off positions of the movable contact piece and thus indicates the automatically triggered opening of the contact point.
  • the housing of the switching device is provided with at least one latching cam which cooperates with the manual control handle and / or with a part of the switching mechanism and / or with the movable contact lever and serves to latch it.
  • the latching can only be released by manual intervention, namely by actuating the manual control handle. H. be overcome.
  • An advantageous embodiment of the invention provides that a latching cam is arranged in at least one flat shell of the housing of the electrical switching device, which interacts with the switching mechanism in such a way that when the switching device is triggered automatically, the manual control handle is held in an intermediate position, which indicates the automatic triggering, and from which it can only reach its two end positions by manual actuation.
  • the locking cam can be integrally formed on the flat shell.
  • the locking cam is formed on a holding part which is inserted into the flat shell of the housing.
  • the position of the locking cam is also provided so that it cooperates with a toggle lever belonging to the switching mechanism, which is articulated to the manual control handle.
  • the holding part provided with the latching cams is made of elastic material. It is provided that, for example, the holding part designed as a sheet metal strip is provided with respectively angled bends at its two ends, the legs of which have different lengths, the shorter leg serving as locking cams and the longer leg being supported on the switching mechanism.
  • a correspondingly shaped part made of insulating material e.g. B. injectable plastic, can be provided as a holding part which is inserted into the housing.
  • the sheet metal strip near the bend of the longer leg has two oppositely arranged indentations on its longitudinal edges, which cooperate with holding pins of the switching mechanism or the housing, on which the holding part is centered.
  • a further advantageous development of the invention consists in that the flat shell, which is provided for receiving the holding part, is provided with a groove which serves to guide the holding part.
  • the manual shift lever can only be fixed from its intermediate position in one end position and in particular only in the off position.
  • the holding part formed from resilient material is inserted into the half-shell in such a way that the latching lug formed on it resiliently acts upon the actuating forces resulting therefrom when the manual control handle is operated manually yields, so that the rear derailleur and thus the manual control handle can reach its end position.
  • Another solution can be that the holding part in the area of its longitudinal strip has a slight bend pointing towards the manual control handle towards the switching mechanism, as a result of which the end of the holding part provided with the locking cam protrudes slightly and thus forms a distance from the housing wall which occurs when the locking cam is acted upon decreased.
  • the use of a holding part provided with a latching cam is provided in a commercially available switching device with a switching mechanism and a manual control handle corresponding to a movable contact piece, the use of the holding part being able to take place as required and depending on whether the special display of the automatic triggering of the electrical switching device is required.
  • the intended function of the switchgear is not affected.
  • FIG. 1 shows the side view of an electrical switching device 10 which has a housing formed from two half-shells 12, of which only one half-shell 12 can be seen here.
  • the lifelike representation of the built-in parts of the switching device 10 has been disregarded, ie a manual control handle 14 and a toggle lever 18 associated with the switch mechanism 16 and a movable contact lever 20 coupled to it are shown schematically, while the other built-in parts are completely omitted since they are not important for understanding the invention.
  • the switch position shown in FIG. 1 corresponds to the switch-off position of the movable contact lever 20, which, due to the mechanical coupling with the manual switch handle 14, assumes a defined end position.
  • the movable contact lever 20 corresponds to a fixedly arranged contact piece 22. Furthermore, in the area of the switching mechanism 16 there is a projection serving as a locking cam 24, which is arranged such that it cooperates with the switching mechanism 16 in a certain switching position.
  • FIG. 2 shows a longitudinal section through the arrangement according to FIG. 1 along the section line I-I, from which the depth and position of the aforementioned parts can be seen.
  • toggle lever 18 extends in the thickness direction of the switching device 10 or the half-shell 12 to such an extent that it has a common contact surface with the locking cam 24.
  • FIG. 3 shows the electrical switching device 10 known from FIG. 1 in the switched-on position of its movable contact lever 20, the manual switch handle 14 having assumed its other end position pivoted by approximately 90 ° with respect to the end position shown in FIG. From this view it can be seen that the toggle lever 18 of the switching mechanism 16 assumes a position remote from the locking cam 24.
  • FIG. 5 shows the electrical switching device 10 known from FIGS. 1 and 3, the movable contact lever 20 of which is lifted off the fixed contact piece 22.
  • the hand control handle 14 connected to it via the toggle lever 18 is in an intermediate position which lies between the end positions shown in FIG. 1 and FIG. 3. This is due to the fact that the switching device 10 has triggered automatically as a result of a malfunction, the trigger (not shown here) acting on the switching mechanism in such a way that the toggle lever 18 assumes the position shown in FIG. This ensures, on the one hand, that the movable contact lever 20 lifts off the fixed contact piece 22 and, on the other hand, that the toggle lever 18 bears against the detent cam 24, which prevents the return to the position of the manual control handle 14 shown in FIG. 1.
  • FIG. 7 shows a holding part 21 which is formed from a long strip 23, at the ends of which a short leg 24 and a long leg 25 are angled in the same direction.
  • the short leg 24 serves as a locking cam 24, while the long leg 25 is supported on the rear derailleur 16, not shown here, arranged between the two legs 24, 25.
  • any known switching mechanism can be provided as the switching mechanism 16, in which a toggle lever 18 is coupled to the manual control handle 14 and is acted upon by the trigger upon automatic triggering as a result of a fault.
  • a switching mechanism according to German patent application P 33 42 469.1, to which the embodiment of the holding part 21 shown in FIG. 7 is tailored.
  • the function of the holding part 21 is provided in such a way that the toggle lever 18 bears against the locking cam 24 when the automatic triggering takes place by the trigger, not shown in detail.
  • latching cam 24 which is fixedly connected to the housing half-shell 12. It is essential that the restoring force of the switching device 10 lifts the movable contact lever 20 from the fixed contact piece 22 and moves the manual control handle 14 from its end position corresponding to the switch-on position, but it is not sufficient to overcome the latching with the latching cam 24.
