Definitions

  • the invention relates to a Verklinkungs worn with a return device, with a triggering device, with a pressure element and in a housing superimposed support members which are acted in verklinktem state with a force applied via a pressure element pressing force for a spring drive.
  • Verklinkungseinrichturigen for spring drives are used for example on high-voltage circuit breakers.
  • the memory spring contained in a spring-loaded drive can be held in a tensioned state by a latching device.
  • a Verklinkungs Sharp a comparatively large stored energy of the tensioned storage spring is controlled releasable.
  • the latching device has a triggering device which operates with a comparatively low energy compared to the energy to be released.
  • the invention has for its object to provide a Verklinkungs worn for a spring drive available, which can reliably hold large forces and at the time of release releases the power of a memory spring as quickly as possible.
  • the energy required for triggering must be as small as possible.
  • a Verklinkungs worn with a reset device, with a triggering device for generating a force acting in a first direction triggering force, with a pressure element and with an upper and a lower in the latched state in a housing stacked support elements, with at least a coupling are connected to each other so that they have a distance from each other, and which are acted upon in the latched state with a force applied over the pressure element along a line of action pressure force for a spring drive, wherein the lower support member deflected in the latched state by the pressure force against a stop and is held in this position, and are set in the movement paths of the upper and lower support member by guides in the housing, wherein the trajectory for the lower support member substantially perpendicular to Bew the upper support element and the triggering force caused by the triggering device disengages the lower support element from the stop; and in which, upon actuation of the triggering device, the lower support element is displaceable perpendicular to the line of
  • the advantages achieved by the invention are in particular that a large stroke of the pressure element is made possible with a small release stroke, a small release force and low mass of the moving parts.
  • This arrangement also allows a fast response when a trigger command for a spring-loaded drive occurs.
  • the stop may for example be designed such that in a lying directly under the direction of action of the pressure element region of the first guide a recess in the first guide is provided so that the lower support member is deflectable in the direction of action and there in a corresponding acting as a stop Recess is held stable.
  • the stop may also be in an alternative position.
  • the restoring device can be pressed by a spring in the direction of the lower support element.
  • the restoring device can be pressed according to an embodiment either by a compression spring against the lower support element and thus against the tripping force generated by the triggering device or it is designed so that the lower support member by means of a tension spring against the first direction can be pulled.
  • the return device is guided along the first direction in the housing.
  • the return device By guiding the return device in the housing, further auxiliary equipment is unnecessary. This allows a compact housing, which also allows mechanical protection for the return device. In order to enable mobility of the lower support element, the return device can move both back and forth along the first direction.
  • the restoring device and the lower support element by a on the Resetting spring acting coil spring in the direction of the triggering device are movable.
  • the guides each have a linear course.
  • Linear guides can be manufactured cost-effectively. In addition, occur in linear guides low frictional forces.
  • At least one support element is guided laterally in the housing integrated slot tracks.
  • the stop point of the upper support element with the coupling can be located above the line of action of the restoring force of the return device.
  • a further advantageous embodiment can provide that the support elements guided in the housing in slot tracks protrude laterally out of the housing at least on one side and the coupling is fastened to their projecting ends.

  • the support elements can be inserted into the slot tracks and connected in a simple manner outside of the housing with the coupling. It can be provided that the support elements are connected angle stiff with the coupling. However, it can also be provided that the support elements are rotatably connected to the coupling. By the rotatable mounting of the support elements, the friction is reduced during movement of the support elements in the slot tracks. As a result, the necessary forces necessary for the movement of the individual movable elements are reduced.
  • the coupling can be set variable in length.
  • This variability of the length of the coupling causes adjustability of the stroke of the pressure element.
  • a force is applied to the support elements and the coupling via the pressing element.
  • For unlatching the support pawl and thus releasing the storage spring of a spring drive a certain stroke through the pressure element and consequently for the support pawl is necessary.
  • Different spring storage drives need to release the support pawl different strokes of the pressure element.
  • a change in the length of the coupling makes it possible to use the Verklinkungs worn for different spring drives with different requirements in terms of the stroke of the pressure element or the support pawl.
  • the end positions of the lower support element can be adjusted accordingly.
  • the pressure element may be variable in its length. This has the advantage that at a change in length of the coupling, the support pawl can still be kept at the same position when the pressure element is extended, for example, in coupling shortening as a countermeasure.
