Definitions
- the invention relates to an electromagnetic relay
- a contact system which has fixed and movable contact elements, connecting elements for the movable and fixed contact elements,
- connection elements for the fixed and movable contact elements are anchored and in which connection tracks for the fixed and / or movable contact elements are embedded, a magnet system being formed by the excitation coil, the core and the armature.
- a relay of the type mentioned is known for example from DE 195 20 220 Cl.
- Additional circuit boards for the electronic circuit components have hitherto been used to integrate an electronic circuit into such a relay. These printed circuit boards have special connection zones for relays, to which the connection elements of a relay are soldered.
- the invention has for its object to provide an electromagnetic relay ⁇ ULTRASONIC which perform together with additional electronic circuit components which control and monitoring functions that combine to form a compact unit to function.
- the focus here is on an easy-to-implement, inexpensive electrical contact between the relay components and the electronic circuit components.
- this aim is achieved in that electronic circuit components, by means of which means for monitoring and / or controlling the relay operating state, are arranged on the base body and connected to the magnet system and / or the contact system via conductor tracks, the conductor tracks being connected by the connecting tracks are formed for the fixed and / or movable contact elements.
- the relay according to the invention represents a constructive solution for the integration of an electronic circuit into an electromagnetic relay, the current-carrying components of the relay additionally being connected to an electronic component, such as an integrated circuit or a semiconductor chip.
- an electronic component such as an integrated circuit or a semiconductor chip.
- the connecting tracks thus also implement the interconnection of the electronic circuit components with the respective relay components.
- the relay according to the invention thus offers the advantage that no additional conductor track carriers or conductor railways are required to integrate an electronic circuit in a relay.
- connection elements for signal coupling can be anchored in the base body, which are connected to the electronic circuit components via the conductor tracks.
- connection elements for signal decoupling can also be anchored in the base body.
- the winding connection elements are preferably connected to the conductor tracks for the electronic circuit components, for example via insulation displacement connections.
- the base body is preferably formed by extrusion coating of the connecting tracks and connecting elements.
- the extrusion coating of the connecting tracks and the connecting elements can have cutouts for the electronic circuit components. This offers the advantage that the electronic circuit components are to be applied to the connecting tracks only after the U injection process. In particular in the case of semiconductor chips, this avoids unnecessary stress on the bond wires due to the extrusion-coated plastic. Furthermore, the recesses of the extrusion coating can be closed with casting resin, so that the electronic circuit components are embedded therein.
- the connecting tracks are preferably formed by stamped sheet metal parts. Alternatively, it is possible to use a profile tape for the connecting tracks. In another advantageous embodiment, the base body and the connecting tracks are formed by a metallized plastic plate.
- the electronic circuit components can be attached to the connecting tracks by soldering or welding. It is also possible to attach the electronic circuit components using conductive adhesive. Especially in the case of semiconductor chips, it is advantageous that such electronic switching processing components are strengthened by wire bonding to the connection tracks be ⁇ .

- the relay shown in FIG. 1 has a magnet system which is formed by an excitation coil 1, a core 1 a arranged axially in the excitation coil and a pivotable armature 2 arranged below the excitation coil 1.
- the coil former forms downward projections with which it engages around a base body 13.
- these extensions serve to make contact between the field winding and two winding connection elements 9 and 10.
- the field coil 1 is surrounded by a covering 5 made of insulating material, which forms an upper part of the housing.
- a movable contact element, which is mechanically coupled to the armature 2, is formed by a contact spring 4 arranged below the armature 2 and separated from it by an insulating layer 3.
- the contact spring 4 interacts with two fixed contact elements 11 and 12 on the base body 13.
- the fixed and the movable contact elements are connected via connection tracks 14, 14a, 15 and 16 embedded in the base body 13 to connection elements 6, 7 and 8 for the movable and fixed contact elements (see also FIGS. 2 and 3).
- the fixed contact elements can be attached to the connecting tracks either by soldering or by welding.
- the contact spring 4 a downwardly to G around body 13 directed Mulltechniksarm 27 which forms a parallel to the connecting path 15 support surface and is attached to the connecting track 15th
- the base body 13 is formed by overmolding the connecting tracks 14, 14a, 15 and 16 and the connecting elements 6, 7, 8, 9 and 10.
- the base body 13 has a special recess 28 for the contact arm 27 of the contact spring 4 on its upper side.
- the base body 13 has corresponding recesses in the area of the fixed contact elements 11 and 12.

- not only connecting elements between the contact elements and the connecting elements are formed by the connecting tracks 14, 14a, 15 and 16, but also conductor tracks which produce the interconnection of the integrated circuit 17 with the contact elements or the connecting elements.
- the connecting tracks 14, 14a, 15 and 16 are preferably designed as a lead frame, which is punched out of a common sheet metal plate. However, it is also possible for the connecting tracks to be formed either by a profile strip or by a metallized plastic plate.
- FIG. 4 shows an alternative design of the connection tracks, the connection between the connection elements 6, 7 and 8 and three connection elements 23, 24 and 25 of a semiconductor chip 22 being produced by the connection tracks 14, 15 and 16.
- the semiconductor chip 22 becomes due to the load on the connection elements 23, 24 and 25 formed by bond wires connected by the overmolded plastic only after the overmolding of the connecting tracks 14, 15 and 16.
