Definitions
- the invention relates to an electromagnetic
- Switchgear with a magnet system comprising an armature and a yoke, with movable contact parts held in a movable contact carrier, which form opener and closer contacts with fixed contact parts, the yoke being elastically suspended in the closing direction of the magnet system and at a distance w from the armature in the exhibition lies.
- a generic switching device is known from EP 0 358 050 B1.
- the contact carrier is elastically connected to the armature in such a way that further movement of the armature is possible without actuation of the normally open contact when the normally closed contact is welded.
- the magnet system here has a yoke that is elastically suspended in the closing direction of the magnet system.
- This elastic suspension, the elastic connection between the armature and the contact carrier and the elasticity of the movable contact parts are coordinated with one another in such a way that the deflection paths of the armature and yoke are approximately the same size when the normally closed contact and the closed magnet system are welded together. In this way, when opening contacts are welded, the magnet system is closed to prevent the magnet coil from burning out.
- the armature is elastically connected to the contact carrier via a relatively long leaf spring, which however takes up a lot of space in the housing of the switching device.
- the invention has for its object to provide an electromagnetic switching device of the type mentioned above, with which the conditions for positively driven contacts in the event of a malfunction are easily complied with in accordance with the regulations of the professional association.
- the object is achieved by such a design of the elastic suspension of the yoke, which, after switching on the magnet system with a welded opener contact, allows the yoke to move until the magnet system closes, the elastic mounting being realized by a conical spring inserted between the yoke and a coil body and the maximum pressure x of the conical spring in the OFF position is at least as large as the distance w reduced by the opening pressure d.
- the contact carrier is connected to the armature by a leaf spring in a narrowed area, and the narrowed area forms cavities in the switchgear housing in which there are back pressure springs acting on the contact carrier.
- FIG. 1 shows the switching device according to the invention in a schematic illustration in side view in section in the OFF representation
- FIG. 2 shows the switching device according to FIG. 1 in the normal ON position
- FIG. 3 in the ON position with a welded break contact.
- the electromagnetic switching device 1 shows an electromagnetic switching device 1 in the OFF position with a housing 2 indicated here in principle, in which a contact carrier 3 is displaceably guided. Furthermore, the electromagnetic switching device 1 comprises a magnet system which comprises an armature 4, a yoke 5 and a coil with a coil body 6. Contact bridges 8 are held in the contact carrier 3 by means of contact pressure springs, which, together with the contacts (not shown here) connected to them, form movable contact parts. the. These form normally open contacts 9 and normally open contacts 10 with fixed contact parts, also not shown here. The armature 4 and the contact carrier 3 are connected to one another via a relatively rigid leaf spring 11.
- connection is almost inelastic, so that a relative movement of the armature 4 to the contact carrier 3 in the closing direction has negligible importance for the function in operation.
- 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. These recesses 13 are located on the side facing the coil former 6 in the formations 14 of the contact carrier 3, which form a region which is narrower than the other width of the contact carrier 3. This results in two cavities 15 towards the housing 2, in which two back pressure springs 16 are held to hold the contact carrier 3 in the OFF position.
- the yoke 5 is mounted on the bottom 17 of the housing 2, it being held by a conical spring 18 which is supported on the coil former 6.
- the armature 4 and the yoke 5 are at a distance w, the so-called magnetic path, from one another.
- the spring-elastic mounting of the yoke 5 enables its movement in the closing direction, which apart from the distance w from the armature 4 is limited by the dimension x, ie the maximum possible compression of the conical spring 18 to a block dimension.
- the armature 4 moves from the position shown in FIG. 1 into the position shown in FIG.
- the contact bridges 8 of the normally closed contacts 9 are separated from the fixed contact parts, not shown, and the contact bridges 8 of the normally open contacts 10 come into contact with further fixed contact parts as a normally open contact.
- the contact pressure springs 7 of the normally closed contacts 9 relax and the contact pressure springs 7 of the normally open contacts 10 are compressed.
- an NC contact 9 welds in the OFF position according to FIG. 1 when the magnet system is excited, the armature 4 can only move by the opening pressure d, as shown in FIG. 3.
- the contact bridge 8 held by welding comes into engagement with the edge 19 of the window in the contact carrier 3 and prevents its further movement.
- the leaf spring 11 Since the leaf spring 11 is relatively short and inelastic, the relative movement of the armature 4 to the contact carrier 3 in the closing direction, which may still occur, is negligible. Burning out of the coil is prevented in this case by the fact that the yoke 5 can move due to its spring-elastic mounting until the magnet system closes. This presupposes that the dimension x, ie the maximum pressure of the conical spring 16 in the OFF position, is at least as large as the distance w or magnetic path reduced by the opening pressure d, ie the condition applies
