Definitions

  • the invention relates to a protective switching device in which a manual control acts via a switch lock on at least one movable contact arm, which forms a contact pair, in detail according to the preamble of claim 1.
  • the switch lock has a latching point between a pawl and a release lever in a kinematics , See e.g. FR-A-255 29 30. Shocks that can occur when the contact pieces meet when switched on travel as shock waves through the switch lock. In the sensitive latch, this can lead to unlatching and unwanted switching off. Such shock waves are difficult to avoid, in particular in the case of modernly designed switch locks with a surge switch-on or a pulse-like switch-on. Up to now, attempts have usually been made to achieve adequate damping in practice by the spatial distance between the shock source and the latching.
  • the invention has for its object a protective switching device to develop the the Latch maintained securely.
  • a Protective switching device when latching in terms of Direction in which force is exerted as a result of the formation of the kinematics is possible due to a switching shock decoupling distance in this direction.
  • This distance can especially between the pawl and its support, on the release lever, be set up when latching, followed by the distance element is withdrawn, so that there is a decoupling buffer zone in the joints can leak without the pawl from its release lever drops.
  • the protective switching device can be equipped with a be pivotable hand control provided over a Switch lock acts on a movable contact arm that forms a contact pair with a fixed contact piece.
  • the switch lock can continue, as is the case with a circuit breaker It is common to be designed so that when unlatching a pawl resting on a release lever as a result the action of a trigger regardless of position of the manual control element there is a contact opening. at such protective switching devices is provided that a spacing element when latching the pawl with the Release lever with respect to the direction in which the Training of the kinematics is possible, a decoupling distance in this Direction.
  • the protective switching device can in particular be a switch lock have, the jack in a portable Bear the movable contact arms directly or indirectly leads, and its release lever arranged in a fixed bearing and supports the movable contact arm.
  • the Jack can continue with a coupling rod to the hand control be connected in another portable warehouse.
  • the spacing element can then advantageously be a contour disk be in the off position of the Manual control element operated switch lock the release lever puts them at a distance and in the switch-on position up to the latch contour is withdrawn. This makes it easier Way of engagement of the spacing element and retracting in the on position in easier Way guaranteed.
  • the contour disc can be in the pawl bearing for the coupling rod be rotatably supported and by the coupling rod by drivers arranged on the contour disk, be performed.
  • the protective switching device has a manual control element 1 and a key switch, from which the latching point between the pawl 2 and a trigger lever 3 illustrated are, wherein a contact arm 4 rotatably on the Pawl is articulated and has a contact piece 5 which against a fixed contact piece 6 works and with this forms a contact pair.
  • a contact arm 4 rotatably on the Pawl is articulated and has a contact piece 5 which against a fixed contact piece 6 works and with this forms a contact pair.
  • a decoupling distance 8 in the direction 9 in the consequence of the formation of the kinematics the key switch of a force due to a Switching shock is possible.
  • Usual contact and switch springs are illustrated here by compression springs 10.
  • Detectors usually a magnetic trigger and a Thermal triggers are used to promote clarity not shown here.
  • a pivotable manual control element 1 via a coupling rod 11 and the switching lock with the movable Contact arm 4 connected.
  • the trigger lever 3 is in a fixed position Bearing 12 arranged and supports the movable contact arm 4 in the latched position.
  • the coupling rod 11 is with the pawl 2 in a portable bearing 13th connected.
  • the distance-giving element designed according to the principle of a contour disk. In the contoured disk is in the off position, as in FIG. 1 shown against the latch on its contour and causes thereby a decoupling distance 8 in the switch-on position, when the contour disc is pulled back to the ratchet contour is.
  • the distance element in the form of a contour disc can in the bearing 14 of the pawl with the coupling rod 11th be rotatably mounted.
  • the contour disk points in Embodiment carrier 15, through which they from the Coupling rod 11 is guided.
  • the tour can also be done through a Component of the housing or cover.
  • FIGS 1 and 2 Elements of the protective switching device in the manner of an exploded view reproduced to be free of overlaps To illustrate components.
  • a coupling rod between the fixed bearing 12 and the portable bearing 13 is designated 16.
