Definitions
- the invention relates to an electromechanical connecting device according to the kind defined in the preamble of claim 1.
- a generic device is known from DE 199 30 642 AI.
- the generic document describes a current or data supply device with a housing in which a plurality of contact elements designed as flat contacts are arranged, which cooperate with contact elements arranged in a housing of a consumer connection or data acquisition device, also designed as flat contacts, for producing a connecting device from a power source to a consumer.
- the current or data supply device has a switching magnet and the consumer connection or data take-off device has a trigger magnet.
- the contact elements of the current or data supply device are each individually connected to a current, voltage or pulse source via line connections.
- the contact elements are cast in an elastic wall of the housing, flush with the surface of the housing or the surface of the elastic wall.
- a contact surface with magnetic energy allows the contact elements of the power or data supply device and the consumer connection or data collection device to lie completely flat and exactly centered on one another. The prerequisite for this is the elastic wall, which allows a corresponding movement with freedom of movement in the axial and radial directions.
- connection with higher voltages or amperages, such as a 110 volt or 220 volt connection
- contact elements of the current or data acquisition device only in the case of a connection to the consumer connection or data acquisition device.
- Data feed device are powered.
- EP 0 573 471 for this, reference is made to EP 0 573 471.
- DE 199 30 642 AI provides in one embodiment that a switching magnet is provided in each case, which is mechanically fixed over three ribs which are uniformly distributed over the circumference and which are not intended to be electrically conductive, with contact elements, also in the form of flat contacts.
- three switching magnets are provided, which are embedded in the elastic wall together with their contact elements connected via the ribs. When opening set a mirrored consumer switching or data acquisition device, three contact elements of each switching magnet come in flat contact with the contact elements of the other device due to the elasticity of the wall.
- Such a surface contact can be produced in accordance with DE 199 30 642 AI perfectly with up to three contact elements per switching magnet. Depending on the size of the housing, any number of switching magnets, each with up to three contact elements, can be accommodated.
- the present invention is therefore based on the object of improving an electromechanical connecting device of the type mentioned at the outset in such a way that multipole contact connections can also be produced in a space-saving manner, in a simple manner and with a secure contact connection.
- a power or data supply device according to the invention or a consumer connection or data take-off device results from claim 22.
- the arrangement of the connecting element with up to three contact elements that is movable with respect to the switching magnet can be realized in a simple manner in a particularly space-saving manner, since for this purpose the diameter which the switching magnet has with its three contact elements does not have to be exceeded or only slightly. This results from the fact that the connecting member to ⁇ the back facing away from the flat contacts of the switching magnet is arranged and the contact elements extend from there to the • surface of the elastic wall. The contact elements of the connecting element thus enclose the switching magnet.
- the inventor has recognized that the magnetic force necessary for the advantageous connection of the current or data supply device and the consumer connection or data take-off device can be applied for the contact elements of the connecting element from the previously unused magnetic rear side of the switching magnet.
- the arrangement of the connecting element according to the invention can only be realized by this knowledge.
- both the switching magnet and the connecting element are arranged in the at least partially elastic wall, they can become connected when the two devices (the current or data supply device and the consumer connection or data output) are connected. Align device) align due to the magnetic force in the direction of the contact elements of the other device and thus establish an optimal surface contact connection.
- the electromechanical connecting device according to the invention can be used in different ways in the most varied technical fields.
- a preferred area of application is e.g. the extra-low voltage range for the transmission of extra-low voltages with very low voltages (e.g. ⁇ 24 volts) in order to generate, carry out or transmit control voltages, switching pulses or data transmissions.
- a power supply device and a consumer switching device are referred to below, although of course this also means devices that are provided exclusively or also in connection with voltage or pulse forwarding for data transmission. Of course, the transmission of audio signals is also possible in this way.
- the contact elements of the two devices can also be placed in an elastic wall, e.g. a plastic membrane.
- one of the two parts interacting in switching contact is designed as a magnet and the other as a magnetic part.
- the magnetically acting parts of the parts which are assigned to one another Power supply device and the consumer switching device as magnetic parts, each with opposite polarities.
- each magnetic part has mutually differently polarized magnetic particles next to one another, which accordingly correspond with a magnetic part to the other device polarized magnetic particles work together.
- Such an embodiment is described in principle in DE 195 12 334 Cl.
- An embodiment of the devices with a working or magnetic slide, which is in the rest position by a permanent magnet, i.e. is in a non-current-transmitting position is described in EP 0 573 471.
- three magnets can be dispensed with, for example, in a conventional arrangement of 18 poles, in which six magnets were previously necessary.
- the electromechanical connection device can be manufactured much more cost-effectively.
- the device according to the invention only requires the space required by a previously 9-pin electromechanical connecting device. Since the poles are generally arranged in a circular housing, the diameter of the housing is reduced to significantly less than half the previous size.
- Mobility enables an independent and simple alignment of the contact elements on the contact elements of the respective other device.
- the distance between the connecting member and the switching magnet can advantageously be chosen such that even after contacting the flat contacts with the flat contacts of the respective other device, there is a distance between the connecting member and the switching magnet. This ensures that the contact elements can align in an advantageous manner. In addition, it is ensured that the switching magnet is not attracted or unwanted by the connecting member. from the contact elements of each other. Facility is lifted off.
- the maintenance of the desired distance between the connecting member and the switching element can also be ensured by embedding the contact elements in the elastic wall. This can be achieved, for example, by choosing an appropriate Shore value for the elastic wall.
- the connecting member and the switching magnet have a bore for receiving a contact element designed as a contact pin and the contact pin to the switching magnet or. the link is movable.
- a contact pin which advantageously extends from one of the elastic walls extends away from the back of the connecting member facing away from the surface of the elastic wall, it is possible to accommodate seven poles in a housing in which so far only the arrangement of three poles was possible.
- the contact pin is cast into the elastic wall in an advantageous manner analogous to the other contact elements.
- the contact pin has a magnet at one end facing away from its flat contact.
- This magnet advantageously reacts to the connecting member, which can be made of iron, for example, or into which an iron plate is incorporated.
- the contact pin is thus moved by its magnetic end towards the contact pin of the other device until it comes into contact with it.
- the contact pin has a stop for limiting the path.
- the elastic wall which leaves the contact pin a defined range of motion, can also serve as a limitation of the path.

- Fig. 6 is a perspective view of a power supply or consumer switching device with a housing in a rear view.
- the electromechanical connecting device according to the invention is in principle already known from DE 199 30 642 A1, in particular from the exemplary embodiment according to FIG. 3, so that only the features relevant to the invention are discussed in more detail below.
- Figures 1 to 6 show a power or data supply device 1 or a consumer connection or data take-off device. Since the construction of the devices can in principle be identical with regard to the features relevant according to the invention, only one power supply device 1 is referred to below with reference to the exemplary embodiment. Of course, the features according to the invention can also be transferred to a data feed device, a consumer connection device, a data take-off device or the like.
- the power supply device 1 has an end face designed as an elastic wall 2, into which six contact elements 3 are integrated.
- the surface 2a of the elastic wall 2 of the power supply device 1 adjoins a corresponding wall of a consumer connection device in the switched state in such a way that the contact elements 3 of the two devices come into contact with one another.
- the end of the contact elements 3 facing away from the elastic wall 2 can be connected to a source of current or impulse (not shown).
- the contact elements 3 are arranged in the elastic wall 2 such that the contact elements 3 formed in this area with flat contacts 4 are approximately flush with the surface 2 a of the elastic wall 2.
- three contact elements 3a of the power supply device 1 are mechanically firmly connected by a switching magnet 5.
- Three further contact elements 3b are mechanically firmly connected to a magnetically influenceable connecting member 6.
- the magnetically influenceable connecting member 6 is arranged on the rear side of the switching magnet 5 facing away from the flat contacts 4.
- the contact elements 3b extend from the connecting member 6 to the surface 2a of the elastic wall 2.
- the current supply device 1 thus has a first contact element unit 7, in which three contact elements 3a are connected to the switching magnet 5, and a second contact element unit 8, in which three contact elements 3b are connected to the connecting member 6.
- Recesses 10 are provided between the first contact element unit 7 or the switching magnet 5 and a housing 9 shown in FIGS. 5 and 6, which allow the contact elements 3b of the second contact element unit 8 to pass to the surface 2a of the elastic wall 2.
- the contact element unit 7 which is designed in the form of a tripod, it basically has a triangular shape, the long sides of which are curved inwards.
- the second contact element unit 8 has an identical structure, but is arranged offset such that the tips of the triangle are aligned with the convexities of the long sides of the first contact element unit 7.
- the switching magnet 5 and the connecting member 6 are embedded in a non-conductive carrier layer 11, which gives both the first contact element unit 7 and the second contact element unit 8 the shape already described.
- the non-conductive carrier layer 11 is formed from plastic, which ensures cost-effective and simple manufacture and, moreover, the contact elements 3a and 3b can be embedded in a simple manner.
- the switching magnet 5 and the connecting member 6 are movable relative to one another.
- a common connection point exists only through the common embedding of the contact elements 3a and 3b in the elastic wall 2, which, however, allows the flexibility necessary for an advantageous connection of the power supply device 1 to a consumer switching device.
- the elastic wall 2 is relatively thin in the exemplary embodiment and the contact elements 3a or 3b are movable in their rear region ensures a sufficient stroke. In general, a stroke movement of, for example, 0.1 to 0.5 mm should be sufficient to get one to achieve safe surface contact.
- the mobility between the connecting member 6 and the switching magnet 5 is accordingly promoted by the air gap 12 shown in FIG. 2.
- the air gap 12 can also be filled with an elastic, non-conductive layer, insofar as this allows the necessary mobility. It is important that the connecting member 6 or the switching magnet 5 can be inclined slightly in order to provide an advantageous surface connection between the power supply device 1 and to generate a consumer connection device.
- first contact element unit 7 As can be seen in FIGS. 1 and 2, a space is also provided between the first contact element unit 7 and the second contact element unit 8, which can be filled with air, gas or an elastic, non-conductive material as required.
- the freedom of movement of the contact elements 3a and 3b should not be unnecessarily restricted by this.
- FIG. 2 shows an embodiment in which the connecting member 6 and the switching magnet 5 have a bore for receiving a contact element designed as a contact pin 13.
- the bore in the connecting member 6 and the switching element 5 is isolated in the direction of the contact pin 13.
- the contact pin 13 and the bores are designed such that the contact pin 13 is movable to the first contact element unit 7 or the switching magnet 5 and the second contact element unit 8 or the connecting member 6.
- the freedom of movement of the contact pin 13 is restricted by the elasticity of the elastic wall 2.
- the contact pin 13 extends from a rear side of the connecting member 6 facing away from the elastic wall 2 to the surface 2a of the elastic wall 2.
- the necessary movement of the contact pin 13 in the direction of a contact element of a device with which the power supply device 1 is to be switched becomes in this case generated by a magnet 14 which is arranged at an end facing away from the surface contact 4 of the contact pin 13.
- the magnet 14 reacts to the connecting member 6 and enables movement of the entire contact pin 13 in the direction of the elastic wall 2.
- the contact pin 13 can have a stop to limit the path. This stop can of course also be supplemented or replaced by the elastic wall 2.
- the first contact element unit 7 as well as the second contact element unit 8 and possibly the contact pin 13 can be one of several units which are accommodated in a common housing (not shown) for forming a multipole connecting device.
- three such units can form an 18-pin connection device or, including the contact pin 13, a 21-pin connection device.
- the elastic wall 2 can be completely or only partially elastic, as required.
- a front view of the elastic wall 2 with the contact elements 3a and 3b can be seen in FIG. 3.
- the housing 9 can be liquid-tight with the elastic wall 2, which can consist, for example, of a plastic membrane.
- a particularly firm connection can also be produced in one embodiment in that the housing 9 and the elastic wall 2 are produced in a two-spray process in which two different plastics are joined together.
- an end face of the housing 9 facing a consumer connection device can have a cutout 15, which enables the power supply device 1 to be attached simply and in a defined manner to a consumer connection device.
- FIG. 4 shows a rear view of the contact element units 7 and 8.
- a connection to a current or pulse-generating source can be made, for example, with flexible conductor tracks or conductor foils, which are cut out accordingly.
- the contact elements 3a or 3b can be provided with a path limitation, not shown in any more detail.
- the switching magnet 5 or the magnet 14 can be coded in such a way that it has a plurality of small magnetic particles with different polarity, each on magnetic particles of opposite polarity from another device in the switched state to meet. A particularly precise and secure connection can thus be created, which excludes the possibility of incorrect switching. In general, however, it should be sufficient to use a normal, non-coded magnet. It should also be sufficient if only the power supply device 1 or the consumer connection device contains a magnet 5. The design with an elastic wall 2 on one of the two devices is also sufficient. This applies in particular if one of the two devices is arranged at a sensitive point, for example on a car, at which the attraction of metal particles by the magnet is undesirable.
- the contact elements 3a are moved in a first step from the switching magnet 5 in the direction of the consumer switching device, since the switching magnet 5 is attracted to the consumer switching device by a correspondingly opposite pole magnet or an iron plate or the like.
- the switching magnet 5 pulls the connecting member 6 and thus the contact elements 3b with it in the direction of the consumer switching device until the contact elements 3a, 3b of the two devices make surface contact. Due to the movement of the connecting member 6, a possibly inserted contact pin 13 is moved due to its magnet 14 in the direction of the consumer connection device moves until the contact pin 13 also flatly touches a corresponding counterpart.
