Definitions

  • the invention relates to a switching device, in particular for electrical circuits, with an electromagnet, the armature of which moves essentially perpendicular to the direction of movement of the switching elements and of the plunger which transmits these elements in armature movement, with an approximately circular sector-shaped between armature and plunger in order to form a transverse to the Tappet extending axis pivotable movement transmission element is arranged.
  • a switching device was known from DE-C-1 290 229 in which the armature of an electromagnet is connected to a plunger actuating the contacts via an angle lever pivotally held on a housing-fixed axis, the free ends of the legs of the angle lever being connected to the armature or the plunger is articulated.
  • the aim of the invention is to provide a switching device of the type mentioned that is characterized by a simple and compact structure and in which a positive coupling between the plunger actuating the contacts and the armature is ensured.
  • the electromagnet surrounds the plunger in a plane transverse to the longitudinal direction of the plunger, that the plunger - at least over part of its length - is designed as a toothed rack, while the approximately circular sector-shaped movement transmission element is formed by a pinion sector which is connected to the formed as a rack part of the plunger, and that the pinion sector and the armature of the electromagnet by means of parallel to the pivot axis of the pinion sector webs and grooves engage with little play.
  • the armature Due to the positive coupling of the armature of the magnet system with the contacts via the pinion sector and the plunger, the armature can be used in a known manner in any installation position of the switching device as an indication of the position of the contacts.
  • the armature can be provided with an extension penetrating an opening in the housing, the position of which then gives a clear indication of the position of the contacts. So z. B. can also be determined from the outside in a simple manner whether the contacts are welded or whether the armature has not tightened despite a voltage applied to the coil of the switching device.
  • the structure is very compact.
  • the lateral surfaces of the web which secure the engagement between anchor and pinion sector and which run parallel to the pivot axis of the pinion sector are convexly curved in a cross-sectional plane perpendicular to the pivot axis.
  • the cross section is tooth-shaped, which results in a very favorable rolling of the parts in engagement.
  • the movable contacts 20 are coupled via the contact springs 21 with a plunger 12, which is designed in sections as a rack 12 'and in the housing 22, in which the contacts 23 are held together with the terminals, axially is held displaceably.
  • a pinion sector 24 ' meshes with the section of the plunger 12 designed as a toothed rack 12' and can be pivoted about an axis 25 which is held in the housing 22 and runs across the plunger 12.
  • the armature 26 is U-shaped and interacts with a likewise U-shaped core 27, which with its two legs as well
  • the armature 26 is attracted and moves into the coils, as a result of which a force is exerted on the pinion sector 24 'and this is thereby rotated.
  • the plunger 12 the section of which designed as a toothed rack 12 ′ meshes with the pinion sector, is moved downward and the contacts 20, 23 close.
  • the spring 30 'acting on the plunger 12 pushes the plunger and thus the pinion sector 24' back into the starting position, as a result of which the armature returns to its outermost position and the contacts 20 are thereby opened.
  • the core 27 is supported by a leaf spring 31 on a coil body 81, in which the coils, not shown, are embedded and which is fixed in position by projections 32 of the housing 22.
  • FIGS. 1 and 2 there is a coupling between the contacts 20 and the armature 26, which is provided with a display flag 33, which is integrally formed on the armature 26, which, like the core 27, consists of a laminated laminated core which is overmolded with plastic is.
  • This coupling is achieved by a web 34 integrally formed on the pinion sector 24 ′, which engages in a groove 35 of the armature 26.
  • This web has a tooth-like profile in a cross-sectional plane perpendicular to the pivot axis 25 of the pinion sector 24 'in order to enable the projection on the walls of the groove 35 to be easily rolled off.
  • the web 34 of the pinion sector 24 'engaging in the core encloses an angle of approximately 90 ° with its tooth flank lying in the closing direction of the contacts, as a result of which the movement of the core in the ratio of approximately 1: is transferred to the plunger 12.
