Electromechanical connecting device

 

The invention relates to the field of electrical engineering. Electromechanical connecting device has located in the housing of the device tomodachi or data feed, connected through contacts of the circuit with the current source or pulse containing the switching magnets or magnetic switching details and contact elements, and located in the housing of the device connection of the consumer or removal of data containing the tripping magnets or magnetic tripping part, electrically connected with the consumer or the stripper. Connecting device of the consumer or pickup data supplied tripping magnets or magnetic breaking parts and the switching contact elements, due to the connection device, tomodachi or feed data to the device connection of the consumer or data readout can be created connection means in the form of flat contact with the surface of the touch contact elements. At least the contact elements of one of the both devices are at least partially elastic wall of the corresponding housing. The technical result is increased reliability multi contanionship the connecting device according to the restrictive part p. 1 claims.

Generic device described in EP 0573471. Instead of electrical connections through the outlet as the current-carrying or compoglass device and plug the device connection of the consumer to the conductive connection using switching and interrupting devices, both devices as flat contacts provided by made with surface touch the contact elements. Due to this measure conductive connection from the power source to the consumer is greatly simplified and it is also becoming more reliable. In case of connection with a higher voltage and/or higher power supply, for example at a voltage of 110 or 220 volts, the contact elements can be supplied with current through the working sled in the switching device only when the connection with the disconnect device that provides very high reliability and error functions and defeats shock.

However, in the case of connection with low voltage surface contacts have advantages in terms of ease of switching, clearing and reliability of the contact connection. In DE 29610996.7 described low-voltage connection or with a low voltage, whereby the devices R is I.

When using two contact elements or, if necessary, also three contact elements can produce a flawless surface contacts. It's more complicated, however, when the contacts shall be made of several contact elements, as in this case is not provided with a good and reliable fit to each other, interacting with each other of the contact elements in one surface contact.

However, in DE 29610996.7 has already been proposed to provide the contact elements tension springs, however, the multi-pole contact connections this type of connection is relatively complicated and prone to failure.

The basis of the present invention lies therefore, the task of improving the Electromechanical coupling devices of the above kind in such a way that you just and reliable contact connection to create a multi-contact connection.

According to the invention this problem is solved by the characteristics given in the characterizing portion p. 1 formula.

Due to the fact that at least the contact elements of one of the two devices, namely devices tomodachi or filing data or device connecting the two devices between the contact elements on the basis of magnetic efforts can be guided in the direction respectively of the device and thereby to create an optimal surface-contact connection.

Electromechanical connecting device according to the invention can be used in different ways and in different areas. The preferred field of application is, for example, the range of low voltages for transmission of small voltages with very low voltage (e.g., less than 24 In) in order to develop a control voltage, the switching pulses, or to transfer data.

For simplicity, below we are talking only about the device tomodachi and the device connection of the consumer, although, of course, this means also devices provided exclusively or in connection with the transfer voltage or pulses to transmit data. Similarly, in the same way possible, of course, and transmission of audio signals.

To enhance the contact of the connection, for example, to create a higher contact efforts, the contact elements of the two devices, if necessary, can be installed in an elastic wall, for example, in the plastic membrane.

The contact elements can be located separately from the parts of the magnet or magnetic components in the appropriate case or they are both a part of the magnet. In the latter case, planirovanie contact elements or their combination with each other, it is sufficient if one of the two interacting with each other in the switching contact parts are made in the form of a magnet, and the other in the form of a magnetic items.

If you want a very precise combination of different contact elements to each other, combined with each other, the magnetic force of the device, tomodachi and device connection of the consumer operate as parts of a magnet with respectively opposite polarities. Thus, there is a precision and accurately matched switching the connection.

This connection can be further improved in respect of the reliable switching of the connection and prevent you from accidentally switching, if in another implementation of the invention provides that each part of the magnet itself contains next to each other differently polarized magnetic particles, which respectively interact with a part of the magnet of the other device respectively with opposite polarized magnetic particles. Such an implementation is described in principle in DE 19512334 C1. One one of the significant advantages of this implementation is that without a suitably encoded response of the magnet is not created by switching the connection, in which by means of a permanent magnet held in the initial position, i.e. not transmitting the current position, as described, for example, in EP 0573471.

If the contact elements are filled in the elastic wall or installed in it water resistant, it is possible to produce a very reliable connection devices that no failures can be located also in liquid or corrosive environments, or which may be respectively in a hostile environment, for example, in paint shops. Of course, this water-resistant layout is required in both devices. This means that if one of the two devices, there is only one elastic wall, the corresponding wall of the other device must also be designed in such a way that the contact elements are water resistant in the housing wall, in which there are contact elements.

Preferred refinement, and execution of the invention are given in the dependent claims and the exemplary embodiment, is fundamentally described below using the drawings, which depict:

Fig. 1 is a magnified cross-section on line 1-1 of Fig. 2 Electromechanical connecting device according to the invention; and

Fig. 2 is a top view of the device of tomodachi or feed data;

Fig. 3 - look over time elements;

Fig. 4 is another exemplary embodiment, which essentially corresponds to the example in Fig. 1, but additionally includes working sled.

In Fig. 1 and 2 show a device 1 tomodachi or filing data 1A, in which there are four made in the form of surface contacts the contact element 2, interacting with located in the housing For the device 3 connect the consumer or data readout, also made in the form of surface contact elements 4 for the manufacture of the connecting device from the power source to the consumer. The contact elements 2 are made at the same time as the switching magnets or magnetic switching parts, and the contact elements 4 are made at the same time as breaking magnets or magnetic breaking parts. The contact elements 2 of the device 1 tomodachi or data feeds are connected individually connecting wires 5 with a source of current, voltage or pulse (not shown). The same applies to the contact elements 4 of the device 3, the connection of the consumer or removal of data from which the consumer with the respective connecting wires. If necessary, connecting the Pro at the point of pickup current, voltage or pulses. In principle, the device 3 connect the consumer or data readout can be the same design as the device 1 tomodachi or feed data, so the same parts are denoted by the same positions (except for the contact elements 2, 4).

As can be seen from the enlarged image in Fig. 1, the front end side 7 of the contact elements 2 are flat and are at least flush with the surface 1A facing the device 3 connect the consumer. The contact elements 2 is filled in the elastic wall 8 of the casing is also flush with its surface. Elastic wall 8 may consist of different materials. Simple, it is a flexible plastic, for example, the membrane. Wall 8 comprises contact elements 2, at least in the area of the face sides water-resistant or contact elements 2 are mounted in it water resistant and are open only at their front end sides 7.

Inserted or filled in the elastic wall 8 of the contact elements 2 can be completely flat, i.e. without curvature, if they act at the same time by means of magnetic forces. Mechanical flat contact a reliable fit of the contact over the ehniki at least one of the two contact surfaces are made curved, which almost forced way point contact.

The current with the magnetic energy of the contact surface, as it is proposed, according to the invention makes contact elements 2 adjacent to each other completely flat and just tsentrirovannoi. Condition this is an elastic wall 8 according to the invention, which provides a corresponding movement of freedom in the axial and radial directions. Needless to say, the elastic wall 8 should not completely cover the contact elements, as shown in Fig.1. In case of need also to elastic wall 8 formed in the surface area of the membrane and the contact elements thereby were open in the back so that they could move even easier, since, in particular, the rear part of the contact elements must be able to move in all directions, so that surface contact occurred in all end sides 7 of the contact elements 2.

Such surface contact has the advantage in particular for the transmission of high power values, in particular, currents in order to avoid unacceptable ranges of point contact would mean, in addition, the limitation of the sound quality. At such frequencies flow of large currents, in particular, in the signal transmission of high power, which require, respectively, a reliable contact. The contact elements 2 according to the invention meet these requirements, and contact elements can easily be brought into compliance with these requirements in respect of size and handling.

To contact elements 2 are securely held in the elastic wall 8, the contact elements 2 may be provided with extensions, for example, annular ledge 9 in its peripheral wall. The same applies to the elastic wall 8, which has one or more extensions 10 diameter, for example, also in a ring shape so that the entire unit has been securely installed in the housing 1A.

Additionally, the contact elements 2 may also be provided with a restrictor. The latter can be formed, for example, narrowing or grooves 11 in the contact elements 2, in which the switching backlash is the emphasis, for example, in the form of a ring or plate 12. The plate or ring 12 is firmly connected to the housing 1A and/or is retained by the wall 8.

Device 3 connect the consumer or data readout is that the Ali marked the same positions, with the exception of the contact elements 4.

When the handling device 3 connect the consumer or data readout device 1 tomodachi or data feed, and the contact elements 4 of the device 3, the connection of the consumer or removal of data coincide with the contact elements 2 of the device 1 tomodachi or data feed, the contact elements 2 due to the elastic wall 8 “curved” outward or in the direction of the contact elements 4 of the device 3, the connection of the consumer or data readout and, Vice versa, also the contact elements 4 in their elastic wall 8 and therefore create, for all contact elements of good surface touch for all areas of their face sides 7.

The plate or ring 12 acts as a back wall as the stroke limiter for moving towards each other of the contact elements 2, 4 due to the recesses 11, in which the backlash is plate 12. In this case, the contact elements 2, 4 abuts each of the back plate 12. As a rule, the course, for example, 0.1-0.5 mm should be sufficient to achieve a correspondingly reliable surface contact. This means that the backlash of such order between the plate 12 and the recess 11 in the contact elements 2, 4 should be as presternum pressure front membrane do not unnecessarily strained.

The contact elements 4 in 3 device connection of the consumer or removal of data in a simple form of execution may be, if necessary, also in the hard wall, if the elastic wall 8 in the same run, as shown in Fig. 2 wall 8, is not provided, in order to get good contact also with a large number of contact elements 2, 4.

As you can see, this way you can create a connection with an arbitrary number of poles or contact elements respectively with perfect contact. Applications are, for example, robots, such as in the automotive industry, when you need to replace the spray head and to transmit data simultaneously. In particular, in the aggressive environment of the paint shop surface contact elements are of particular advantage in comparison with the known plug connections, which are difficult to clear, thus partly also often damaged and thus become unusable.

Other applications are, for example, trailer hitch vehicles, which, in General, 13-pin, and connecting components of computers and their peripheral devices between suprimer, ship or building with the attendant problems regarding the aggressiveness of the water, particularly salt.

If it is desirable to avoid prolonged application of current to the contact elements 2 of the device 1 tomodachi or submitting data, you only need to provide a working sled between the contact elements 2 and the connecting wires. Such working or the magnetic carrier and the principle of their action are described in EP 0573471.

To create a magnetic connection, it is sufficient if, for example, the contact elements 2 devices tomodachi or supply data in the form of magnets, and the contact elements 4 of the device 3, the connection of the consumer or reading data consist of magnetic material, e.g. iron. Of course, you may, however, reverse the position.

When using only parts of the magnets should be positioned so that the contact elements of the device 1 tomodachi or supply data and device 3 connect the consumer or removal data were lying against each other with different polarity. Exactly the same as that of the Electromechanical connecting device according to EP 0573471 or DE 19512334 C1, may be provided respectively “encoded” magnets 2, 4 as contact is ompaktnaja the location of the contact elements shown in Fig. 3.

Unlike depicted in Fig.1 and 2, the contact elements 2, 4 are simultaneously switching respectively tripping magnets or magnetic components, the contact elements 20 according to Fig. 3 are respectively independently separately from the respective magnets. In Fig. 3 the device 1’ tomodachi or filing data is depicted with three switching magnets 2’. Each of the switching magnet 2’ by means of three equally spaced around the perimeter of the ribs 14, which need not be electrically conductive, is firmly connected with the contact elements 20, in the form of a flat contacts. All three of the switching magnet 2’ together with their connected with them by means of the ribs 14 of the contact elements 20 are mounted in the elastic wall 8’. When putting mirror-symmetrically made device 3’ connection of the consumer or data readout three contact elements 20 of each of the magnet due to the elastic wall 8’ are in surface contact with the contact elements, respectively, of another device, such as surface contact flawlessly created at the contact between the parts number to three.

Needless to say, in Fig. 3 located near dragoneye body in a very tight space to accommodate an arbitrary number of contact elements 20. Of course, in this case, the device can be also circular.

It is evident from Fig. 1 further shows that the elastic wall 8 at its outer periphery in the area of the face sides 7 are supplied towards the outside of the dish 15. Due to this, perform a moisture-proof connection is still better protected.

The same applies to the elastic wall 8 of the device 3, the connection of the consumer or data readout.

If in a very close space should be provided for a large number of contact elements for receiving a connecting device with a large number of poles, and the contact elements 2, 4 are very small in its diameter, it is possible to increase the magnetic forces in one or both devices, i.e., in the device 1 tomodachi or submitting data and/or device 3 connect the consumer or reading data to provide behind or facing away from, respectively, the other device side reinforcing magnet 16 (see dashed line in Fig. 1 together with depicted as a dashed line, respectively, increased body 1A for additional accommodation magnet 16). When connecting both devices to each other enhances the magnet 16 increases the magnetic force and moves back contact e is GCE “viputivatsa or to bend forward and thus occurs more reliable surface-contact connection.

The device 1 tomodachi or filing data can be set with my body 1A in any devices, holders, parts of walls or other devices 17. The same applies to the device 3, the connection of the consumer or data readout.

In Fig. 4 depicts another example implementation, which has in principle the same design as the example implementation of Fig. 1. For this reason, the same parts were saved by the same reference position.

In addition to the exemplary embodiment of Fig. 1 the device 1 tomodachi or data feeds are provided inside the housing 1A work carrier 21. As already mentioned, the principle working of the slide 21 is already described in EP 0573471, so below this is stated very briefly.

As can be seen, in this case, the magnets 2, 4 and the contact elements are arranged separately from each other and re-marked reference position 20’ to the contact elements in the device 1 tomodachi or feed data and the reference position 4’ of the contact elements in the device 3, the connection of the consumer or data readout. The magnets 2 and the connecting wires 5 are connected with the work carrier 21 or are on them. Working rails 21 are held in the initial position retarding magnet 22. Check who your customer or data readout working of the slide 21 in the housing 1A. Instead of delaying the magnet 22 can, of course, also be used as an item, which is ferromagnetic and consequently attracting workers rails 21 placed on them by the magnets 2.

As can be seen, therefore between the connecting wires 5 and the contact elements 20’ has not yet been created conductively connected to the current direction further. Only when skewer device 3 connect the consumer or data readout working sled 21 due to the forces of mutual attraction of the magnets 2, 4 are lifted from its original position against delaying delaying efforts of the magnet 22, and there is contact between the connecting wires 5 and the contact elements 20’ and thereby conductively connected with the contact elements 4’ device 3 connect the consumer or data readout. Needless to say, this magnetic retarding force between the magnet 22 and the magnets 2 should be chosen so that the force of attraction due to the magnets 4 were higher, namely taking into account the fact that the magnets 2, 4 do not reach the surface but slightly shifted backward or sealed (magnets 4 in the elastic wall 8 and the magnets 2 under the lid). When a device is removed 3 connection of the consumer or data readout working sled 2 is ulozhenie. Thus, the contact elements 20’, which are separated in the device 3, the connection of the consumer or data readout have free access, then de-energized.

The device according to the invention can be used including also a very preferred way for comparedate and transmitting signals to mobile phones, which, for example, by the device, allowing you to negotiate without the use of hands, must be installed in the car. In this case, requires a large number of contacts. For the transmission of high frequency signals, which, as a rule, must be equipped with a screen and for which, as a rule, use coaxial cables, the device 1 tomodachi or supply data and device 3 connect the consumer or data readout can be provided with a corresponding connecting contacts for the transmission of high frequency signals.

If because of lack of space to accommodate multiple contact elements 4 can optionally require that the magnets 4 were electrically shielded by an insulating gasket 23 in order to avoid short circuits. For anchoring magnets 4 in the elastic wall 8 and they can be provided with an annular ledges is received an annular groove 25, which includes material working sled 21.

Function similar to the one you perform the notches 11 in Fig. 1, namely the restriction of the curvature of the elastic wall 8, the extension 26 on the reverse side of the contact elements 4’ and the transition to the connecting wires 5. As can be seen, between the extensions 26 and the rear wall of the housing 3A there is a gap, resulting in elastic wall due to the magnetic effort can bend forward only by the amount of backlash.

In Fig. 2 to device 1 tomodachi or data feed, for example, two places of installation of such contacts indicated by the dotted circle 27 for Central coaxial position and a dashed circle 28 for location in a peripheral zone. In accordance with the location of the contacts 27 or 28 in the device 3, the connection of the consumer or data readout should be, respectively, the return contact or response coupling element (not shown).
