Abstract

The invention concerns an electromechanical connection device comprising a switching device which can be connected to a current source via power supply contacts and comprises switching magnets. A tripping device. provided with tripping magnets, can be connected to the switching device. Switching magnets are thus moved from a rest position, against a restraining force, into an operating position, the contact between pairs of contacts and hence the electrical connection between the switching device and the tripping device being established. The switching magnets and the tripping magnets are provided with a special code. A plurality of switching magnets in the outer peripheral area of an operating slide are disposed as segments at a distance from one another. An identical number of tripping magnets with opposite polarity are likewise arranged as segments in the same peripheral area as the switching magnets in the tripping device.

Claims

1. An electromechanical connecting device having a switching mechanism which can be connected via power supply contacts to a current source, including actuating magnets having coded magnet parts in the form of a first specific arrangement of the north and south poles, arranged in a housing as a closed assembly, and connected to a tripping mechanism which exhibits tripping magnets having coded magnet parts in the form of a second specific arrangement of the north and south poles and electrically connectable to a consumer;

said tripping magnet bringing the actuating magnets from a rest position into a working position against a retaining force for producing a contact of contact pairs and an electrical connection between the switching mechanism and the tripping mechanism, the actuating magnets cooperating by means of a coding, with the tripping magnets having oppositely directed coding, thereby realizing specific magnetic fields for the actuating operation;

the housing of the switching mechanism being provided with an earthing ring on a side facing the tripping mechanism, wherein a plurality of actuating magnets are arranged in the outer circumferential region of the operating slide with a spacing from one another with magnet parts having different polarities, and an equal number of tripping magnets having magnet parts of opposite polarity are arranged in the same circumferential region as the actuating magnets in the tripping mechanism and in that the contact pairs exhibit contact pins in the switching mechanism and in the tripping mechanism, the contact pins in the tripping mechanism projecting in the non-connected state from a side facing the switching mechanism and being mounted resiliently in the tripping mechanism.

2. The electromechanical connecting device according to claim 1, wherein the actuating magnets and the tripping magnets are constructed as annular segments.

3. The electromechanical connecting device according to claim 1, wherein the operating slide is constructed at least approximately in a circular fashion.

4. The electromechanical connecting device according to claim 2, wherein a plurality of magnets, which respectively exhibit north and south poles, are arranged distributed over the circumference in the switching mechanism and in the tripping mechanism.

5. The electromechanical connecting device according to claim 4, wherein each magnet is constructed as a quad group having magnets parts of different polarity.

6. The electromechanical connecting device according to claim 5, wherein the magnet parts are arranged in alternating north-south combinations having 180°

symmetry.
