Description

ELECTROMECHANICAL CONNECTION DEVICE DESCRIPTION OF THE INVENTION The invention relates to an electromechanical connection device according to the type most closely defined in the preamble of claim 1. The connection device of this type is described in EP 0 573 471 B1. The previously known connection device, which consists of a switching mechanism, which performs the function of a socket-outlet of the conventional type and a disconnection mechanism, which performs the function of a male plug, provides a connection device, which has a very small overall depth and which also meets the requirements of high security. In the electromechanical connection device according to EP 0 573 471 B1, both of the mechanical and electrical contacts are made by means of magnets. For this purpose, both of the operation slide, which may be connected to the power supply contacts and the drive magnet, are electrically conductive. The power connection is carried directly by means of the contact reinforcements to disconnect the magnets in the disconnection mechanism, which are also electrically conductive. The magnets are surrounded on the outside by a ground connection ring, which is allowed to level in the electrically insulating housing of the switching mechanism. It is disadvantageous in this current conduit, however, that in the case of a short circuit the electrical conductivity leads to loss of the magnetic voltages sensitive to heat. In addition, due to the conduction of the voltage and current by means of the contact reinforcements and the magnets, the previously known device is still of relatively wide construction. Therefore the object of the present invention besides improving the electromechanical connection device mentioned at the beginning, in particular to ensure even greater reliability and to increase the magnetic adhesion. This object is achieved according to the invention by means of the features mentioned in the characterizing part of Claim 1. According to the invention, magnets are no longer involved in current or voltage conduction; that is, they are no longer active. The current itself is carried separately by means of pairs of contacts, which are located in an inner region of the housing, to be accurate between the housing half and the drive magnets. This means that only an electrically conductive bridge is still required for the operation slide, which produces contact with the power supply contacts. The slide that works by itself can be electrically non-conductive together with the drive magnets arranged on it. Another increase in reliability is provided by the arrangement of pairs of contacts in the inner region. In addition, the contact pairs can be constructed to be more stable and thus more reliable, for example in the form of broad contact tips. Another advantage of the separation, according to the invention, of the magnets of the current conduction, is that in this form there are no heat problems with the magnets, since the latter do not participate in driving after all. of the stream. For example, a short circuit may occur, the magnets will not be damaged by the action of heat. Again, the heat which is produced by a possible moisture film can be dissipated in a simple way by means of the grounding ring. This is the case, in particular, when the driving magnets and the disconnection magnets are in contact with the grounding ring in the connected state. Yet another very advantageous refinement of the invention may be that a plurality of driving magnets are arranged as segments spaced apart from each other in the outer circumferential region of the operating slide and that an equal number of disconnecting magnets of opposite polarity are provided. Also disposed as segments in the same circumferential region as the drive magnets in the disconnection mechanism. In this case, the segments can be constructed as annular segments and can be arranged in corresponding groupings on the edge of a circularly constructed operation slider. If the magnet segments are in this case arranged in appropriate configurations, for example north-south alternating combinations having 180 ° of symmetry, it is possible to achieve a very rapid return of the operating slide in the case of rotations of the disconnection mechanism. . The relatively large angular lengths, which occur in this case, increase even in the case of small rotations for the fields of opposite direction and thus for the correspondingly high repulsive forces, with the result that the operation slide returns to the state inactive not connected.

The electromechanical connection device consists of a switching mechanism 1, which replaces the function of the conventional socket-outlet and is usually permanently installed at a desired point, and a disconnection mechanism 2, which replaces the function of a Conventional male plug, which is usually connected to a heatsink which is arranged directly on the heatsink. As soon as an electrically conductive connection is produced between the switch mechanism 1 and the disconnection mechanism 2, the respective heatsink connected to the disconnection mechanism 2, is appropriately supplied with current. In principle, the switching mechanism 1 and the disconnection mechanism 2 are constructed using the same principle as for the electromechanical connection device described in EP 0 573 471 B1. In this way, the switching mechanism 1 presents a closed assembly in a housing 2 of two parts. In the inactive stage, ie when the disconnection mechanism 2 is not placed on the switching mechanism 1, an operation slide 4, on which the drive magnets 5 are arranged in the form of segments, is maintained on the floor of the housing 3 by a ferromagnetic retaining plate 7. The ferromagnetic retaining plate can also be a magnet ring 7.

The driving magnets 5 are arranged in the outer circumferential region of the circular operation spool 4. As can be seen from Figure 4, in this case the drive magnets 5, constructed as annular segments, are arranged distributed over the circumference in a total of 4 groups. Each group consists of two north poles and two south poles, each of which are arranged in a relationship with each other, in such a way that in each case different polarities join together. This means that in a part of the outer segment a south pole and a north pole are located next to each other, and in an inner segment part of a north pole and a south pole face each other. Each group of a segment 5 is arranged in this way inside the housing 3, and has a height such that even in the unconnected state, the segments are guided in a guide ring 6 at least in its upper region . For this purpose, they are appropriately inserted into the upper region within the guide ring 6. The guide ring 6 simultaneously constitutes a ground connection ring, for which purpose it is correspondingly connected to a contact mechanism (not shown), which it is connected to a grounding conductor which terminates in the switching mechanism. Four reconnection springs 8 arranged, evenly distributed over the circumference, ensure that in the unconnected state, the operation slide 4 is further maintained on the annular magnet 7 by an appropriate spring force. At the same time, it ensures that after removal of the disconnect mechanism 2 from the switching mechanism 1, or proper rotation of the two parts relative to each other, the operation slide 4 is brought to bear against the magnet ring 7 again . As can be seen from Figures 2 and 4 the reconnection springs 8 are likewise guided in the guide ring 6. They are respectively located in this arrangement in the free space between the segments 5. The power supply will observe more clearly in the Figure 4. "9" represents a line that conducts current, and "10" represents a neutral conductor. The two lines are left inside a cover 11 of the housing 3 for the power supply contacts 12. In the connected state, an electrically conductive bridge 13 produces, respectively, a power connection from the power supply contacts 12 to the corresponding contact tip 14. This means that a contact tip 14 is assigned to the phase line 9, and the second contact tip 14 is assigned to the neutral conductor 10. Both contact tips 14 are arranged in the cover 11 of the housing 3 and are flush on the upper side with the cover.

It can be seen from Figures 1 and 3, that each of the two bridges 13 is resiliently or resiliently disposed on the operation slide 4, to compensate for the tolerance of the inaccuracies, as well as for the wear and tear with the result that it is always ensures good contact. The disconnection mechanism 2, which also has a closed housing 15 with a cover 16, is provided with the disconnection magnets 17 also constructed as segments. The disconnection magnets 1 7 are arranged in the same shape and at the same point in four square groups. In this arrangement, each group is constructed with reference to its polarity, in such a way that in each case, different polarities face each other by comparison with the driving magnets 5 of switching mechanism 1. This means that in the case of the correct positioning of the disconnection mechanism 2 on the switching mechanism 1, the north and south poles respectively face each other. The desired switching state and thus, the current conduction to the dissipator are achieved in this way. For this purpose, the disconnect mechanism 2 is provided with appropriate lines 26 and 27 leading to a heatsink, with the proviso that the disconnecting device 2 is not disposed directly on or on the heatsink. Since the contact tips 14 are arranged in a region between the housing half and the actuating magnets 5, two contact tips 20 [sic] are disposed in the housing 15 in the region between the housing half and the housing magnets. disconnection 17. The contact tips 18 can also be displaced by the springs 19 in the holes of the housing 15, in such a way that they project slightly with their front ends from the housing 15 in the direction of the switching mechanism 1. This means that when the disconnection mechanism 2 is supported on the switching mechanism 1 and thus in the case of electrical contact switching there is an appropriate reliable contact (see Figure 3). In this case, the contact tips 18 are pushed back correspondingly against the force of the spring 19. The disconnection mechanism 2 is likewise provided with a ground connection ring 20, which faces the ring 6 for ground connection of the switching mechanism 1, furthermore, the ground connection ring 20 of the disconnection mechanism 2 is provided with the ground connection tips 21, which are arranged, distributed over the circumference and each is reconnected by a spring 22 and in this way it projects resiliently from the housing 15 in the direction of the switching mechanism 1. As can be seen from Figure 1, in this arrangement the grounding tips 21 also project from the surface of the housing 15, the tips of Contact 18. This II means that the forward ground connection and a delay ground connection are therefore achieved during switching in a simple manner. In a manner similar to the tips 8 for reconnecting the disconnection mechanism 1 [sic], the grounding tips 21 are located in the interspace, on the circumferential side between the four disconnection magnets 1 7. As can be seen from the Figure 4, the power supply contacts 12 are likewise located in a region between the housing half and the drive magnets 5 or the guide ring 6. Thus, it is not only an electromechanical connection device, produced, which has a small overall depth, but in addition, a device is also produced, which has only a small diameter or width. As mentioned, the grounding ring 6 simultaneously serves as the guide ring for the driving magnets 5, for which purpose the ring surrounds the driving magnets 5 with a slightly appropriate play. In this way a non-jamming and reliable switching is ensured. Several exemplary embodiments for the driving magnets 5 and the disconnection magnets 17 are shown in Figures 5 to 7.

According to Figure 5, a total of only four magnets are arranged on the operation slide 4 in four rings. The disconnection magnets 1 7 of the disconnection mechanism correspondingly have the opposite polarity on the circular segments. According to Figure 6, a north pole and a south pole are respectively combined to form a segment. A total of four segments are arranged, evenly distributed over the circumference. The best solution is achieved by means of a refinement according to Figure 7, which is also described in this form in Figures 1 to 4. In this case, each of the four groups comprises in each case four magnets. This refinement produces alternating north-south combinations that have a 180 ° symmetry. A very rapid return of the operation slide 4 together with the rotation of the disconnection mechanism 2 or of the switching mechanism 1 is achieved with this refinement. On the basis of the large angular lengths, the fields of opposite direction and thus the repulsion forces are produced even in the case of small rotations, as a result of which the operation slide 4 returns to its inactive position and thus it is carried against the magnet ring 7. Furthermore, the circular structure of the operation slide 4 and also of the circular housing 3 of the switching mechanism 1 and of the disconnection mechanism 2, allows a very good control of the switching movement without tips of additional guide The geometric structure is therefore also of simpler configuration. In the case of each direction of displacement or rotation, the magnetic fields of opposite direction act and thus reliably return the operation slide 4. An adapter 23 which allows [sic], the transition to the conventional electrical system with the lampholder- outputs with grounding contacts, or also with another lampholder-outputs, is represented in the principle in Figures 8 and 9. For this purpose, the adapter 23 has tips 24 corresponding to the respective conventional system (and, if appropriate , a ground connection point as well), which are connected inside the lamp socket-corresponding outputs of known design. The adapter 23 is constructed on the inside in the same way as the disconnect mechanism [sic], only the lines 9 and 10 which are replaced by the tips 24. The ground connection ring 6 together with the two contact tips 14 are to be observed in Figure 8. Represented in Figures 10 and 11 there is a separate disconnect mechanism 2 in the form of a male plug 24, which is provided with wires 26 and 27, which lead to a heatsink and they are surrounded in the usual manner with a protective liner 25. The male plug 24 is built in the same way as the disconnection mechanism 2. The disconnection rings 20 together with four grounding prongs 21 can be observed in the Figure 10
