Definitions

  • the invention relates to a locking device for mechanically switching on one of two electromagnetic switching devices arranged next to one another, as long as the other switching device is in its switched-on position, the movable parts of the switching devices being able to be coupled to locking members extending from the locking device.
  • the locking device is provided with a heart-like, axleless rocker in a housing.
  • the locking members are designed here as pin-like parts which extend perpendicular to the plane of movement of the rocker and diametrically apart from one another in the direction of their respective switching devices to be attached. These pin-like parts are guided in a circular arc shape in the recesses provided in the provided rocker movements.
  • the ends of the pin-shaped parts protruding from the housing are inserted through the side walls of the switchgear into grooves of driver links.
  • the housing of the locking device is connected here by means of snap hooks which snap into correspondingly adapted recesses in the switching devices and held on the switching devices.
  • the invention has for its object to improve a locking device of the above type in such a way that coupling to electromagnetic switching devices is possible without special constructive, specific training of the switching devices, the overall depth should not be increased with additional auxiliary switch blocks attached.
  • This is achieved in a simple manner in that the moving parts of the switching devices are the coupling parts for auxiliary switches that can be attached directly to the single auxiliary switch and the locking elements are adapted to these coupling parts, the locking elements being attached in the grid of the coupling parts with a certain surcharge.
  • This makes it possible to place additional retrofittable individual auxiliary switches directly on the contactors, as in a version without mechanical locking. No intermediate housing with intermediate coupling parts is required, with the disadvantage of additional tolerances and wear with regard to the auxiliary switch coupling.
  • the coupling parts are designed like hammer heads and the locking members are slides, the free ends of which run around the hammer head.
  • the other ends of the slide are positively coupled to a locking rocker, the tip of which is supported on a locking contour in the housing of the locking device in the event of a lock.
  • the housing of the locking device is provided with the molded parts adapted to the mounting of the auxiliary switches.
  • the locking device in electromagnetic switchgear of a larger design if the distance of the first auxiliary switch arrangement from the edge of the switchgear is greater than that of smaller contactors.
  • the locking device is applied to the moving parts of the switching devices transversely to the direction of movement can be pushed on and coupled and that at least one slide is provided for releasably latching the locking device on the switching devices.
  • a common slide for coupling with fixed parts of the switching devices can advantageously be present here.
  • the locking device consists of the housing 1, in which a spring 3, which is spring-loaded via a spring 2, is spring-loaded against the direction of movement of locking members 4.
  • the locking members 4 are more or less positively coupled via pins 5 formed on the rocker 3, which protrude into recesses 6 of the locking members 4.
  • the locking members 4 are slidably guided in the housing 1 as a locking slide.
  • the rocker is of triangular design and slides past one of the locking slides with the triangular tip 7 at a short distance from correspondingly shaped surfaces 8 of the housing 1, so that the downward movement of the other locking slide 4 is prevented. This device cannot turn on.
  • the locking slide 4 are also equipped with rectangular openings 9 which are open to the free side, so that a hammer head 10 can be largely inserted in a positive manner, which is integrally formed on the contact bridge support 11 of an electromagnetic switching device 12. Coupling arrangements of this type have become known, for example, from DE-GM 88 05 878.
  • the hammer head 10 is adapted to a hammer head-shaped projection 13 on the housing of the electromagnetic switching device 12, which cooperate with corresponding projections 14 on the housing 1 of the locking device.
  • Two hook-shaped lugs 15 on the housing 1 of the locking device engage when moving the locking device into the operating position in a correspondingly shaped recess 16, so that the housing 1 is firmly connected to the housing of the electromagnetic switching device 12 at three points.
  • a slide 20 is provided for releasable locking.
  • the slide 20 is displaceable against the force of a spring 17 or resilient plastic tongues to release the hammer head-shaped formation.
  • An inclined surface 18 pushes the slider 20 back against the force of the spring when the locking device is placed on it, until it locks behind the hammer-shaped projection 13.
  • the molded shape 19 provided in the housing 1 is arranged in the grid dimension for the spacing of the individual auxiliary switch locations, as can be seen from FIGS. 3 to 6. This results in the possibility of applying the locking device to two electromagnetic switching devices 12 in the ways shown in FIGS. 3 to 6.
  • FIG. 3 to 6 This results in the possibility of applying the locking device to two electromagnetic switching devices 12 in the ways shown in FIGS. 3 to 6.
