Definitions
- the invention relates to an electromagnetic Switchgear with an armature and a yoke Magnet system, with held in a movable contact carrier movable contact parts with fixed contact parts Form NC and NO contacts, with the yoke in Closing direction of the magnet system is suspended elastically and in the exhibition at a distance from the anchor.
- a generic switching device is described in EP 0 358 050 B1 known.
- the contact carrier with the armature is so elastic connected that a welded NC contact Further movement of the armature without actuation of the make contact is possible.
- the magnet system has an in Yoke closing direction of the magnet system on.
- This elastic suspension, the elastic connection between the anchor and the contact carrier and the elasticity the movable contact parts are matched to one another, that with welded NC contact and closed Magnet system the deflection of anchor and yoke, for example are the same size. In this way, when welding NC contacts closed the magnet system to prevent a burnout to prevent the solenoid.
- the anchor is here with the contact carrier elastic via a relatively long leaf spring connected, but what in the housing of the switching device accordingly takes up a lot of space.
- the invention has for its object an electromagnetic To create switching device of the above type, with the the conditions for positively driven contacts in the event of a fault the regulations of the professional association on simple Way are observed.
- the contact carrier is in a narrowed area the anchor is connected by a leaf spring, and the narrowed Area with the switchgear housing forms cavities, in which back pressure springs acting on the contact carrier lie.
- FIG 1 is an electromagnetic in the OFF position Switching device 1 with one indicated here in principle Housing 2 shown, in which a contact carrier 3 slidably is led. It also includes electromagnetic Switching device 1, a magnet system, the armature 4, a Yoke 5 and a coil with a coil body 6 comprises. in the Contact carrier 3 are 7 contact bridges by means of contact pressure springs 8 held together with them here Contacts, not shown, form movable contact parts. These also form not shown here Fixed contact parts in the usual way normally closed 9 and normally open contacts 10. The armature 4 and the contact carrier 3 are over a relatively rigid leaf spring 11 interconnected.
- the Connection is almost inelastic, so that a relative movement of the armature 4 to the contact carrier 3 in the closing direction for the function in the company has negligible importance.
- the Leaf spring 11 is guided through an opening 12 in the armature 4 and is supported with its ends in recesses 13 of the Contact carrier 3 from. These recesses 13 are on the side facing the coil former 6 in the formations 14 of the contact carrier 3, one against the other Form width of the contact carrier 3 narrowed area. This results in two cavities 15 towards the housing 2, in which two keep the contact carrier 3 in the OFF position Back pressure springs 16 are held.
- the yoke 5 is at the bottom 17 of the housing 2, wherein it by a on the bobbin 6 supporting conical spring 18 is held.
- the armature 4 and the yoke 5 at a distance w so-called magnetic path, apart.
- the resilient Bracket of the yoke 5 allows its movement in Closing direction, this apart from the distance w to Anchor 4 by dimension x, i.e. the maximum possible compression the conical spring 18 is limited to block dimensions.
