p0001The electrical connection apparatus

p0002The invention relates to an electrical connection device according to the closer defined in the preamble of claim 1.

p0003A connection device of this type is described in WO 01/03249 Al.

p0004The elastic arrangement of the contact elements at least one device can be optimally aligned to each other and produce a very good surface contact and multiple contacts. In this way, higher amperage can be transferred or forward.

p0005The present invention has for its object to improve the prior art electromechanical connecting device further, especially for mass production and for a variety of contact connections to make more suitable.

p0006This object is achieved in that a plurality of contact elements at least one of the two devices are arranged side by side in a grid-like configuration that the contact elements inserted into the rasterformige embodiment are elastically suspended, and that the rasterformige configuration on the side facing away from the contact elements side by a pressing bridge rests. The arrangement of the contact elements of a device in the form of a grid configuration can at least be in a confined space, a plurality of contact connections provide. In practice, the contact elements such as letters are arranged side by side of a printing press, the length can be selected virtually. Through the elastic support the individual contact elements are freely movable from one another, resulting in optimum contact connections with surface contact. The press bridge also ensures proper surface contact due to the common storage or support of the contact elements on their back. The necessary resilience for the contact elements can be achieved in a very advantageous embodiment of the invention characterized in that the pressure bridge is formed elastically. By elastic pressing bridge can be compensated in addition to a very good surface contact and tolerances zungenauigkeiten. At the same time the pressure will be evenly distributed to the individual contact elements.

p0007Additionally or alternatively, the contact elements may be at least partially embedded in an elastic sheath.

p0008If necessary, the device according to the grid-like skeleton can be reserved, similar to magazine printing letters.

p0009In an advantageous embodiment of the invention can be provided that the current or data transmitter device and the power purchase or data pickup mechanism respectively Magnetic bodies are provided, wherein the magnetic body of the power purchase or data pickup mechanism disposed opposite to the magnetic bodies of Stromgeber- or Datengeberein- direction.

p0010The inventive device can be spot-on sheet-like contact, also blind, achieve very short distances and with the connivance of larger tolerances of connected electrically parts.

p0011In an advantageous design configuration can be provided that the rasterformige embodiment is formed by a skeleton, the skeleton may have at least approximately a running with rectangular turns meander.

p0012By meandering invention can practically make the piece a grid-like skeleton, which can be cut to length according to any length. then the contact elements are inserted and provided in an advantageous manner by injection molding with the elastic envelope in the individual meander, and the individual meander can be filled in accordance with the injection. However, it is also blank, thus increasing the elasticity is achieved through the air gap so that present the rearwardly open meander.^' If one makes the slightly narrower meander there when the thickness of the contact elements, these are held by clamping action safely in the forwardly projecting meanders. To surface contact magnification can be provided that two contact elements adjacent to each other are connected by a conductive bridge portion.

p0013Of course, two contact elements of the other means are also connected to each other with a conductive bridge portion in this case. In this way, a considerably larger contact area is provided, whereby even higher currents may be transmitted at this point.

p0014Instead of connecting the current or Datengebereinrich- device with the power purchase or data acceptance facility via the magnetic body by generating a magnetic holding force, the two institutions are of course interconnected in any other desired manner, such as a non-positive or positive connection with or without locks ,

p0015Advantageous developments and refinements emerge from the remaining subclaims and from the exemplary embodiment described below in principle with reference to the drawing.

p0016It shows:

p00171 shows a longitudinal section through the inventive electrical connection device according to the line II of Figure 2..; . Fig. 2 shows a cross section through the inventive electrical connection apparatus of Fig 1 along the line II-II; and

p0018Application and use case for the electrical connection device can be the same as those described in WO 01/03249 Al. WO 01/03249 AI is simultaneously also the disclosure of the present invention, so far it has not be described in detail.

p0019Figures 1 and 2 each show a current or Datenge- siphoning device 1 with a housing 2 in which a plurality of adjacently formed as surface contacts contact elements 3 are arranged. In the encoder housing 2 several magnetic body 4 in the form of iron cores or magnets are spaced from each other two or if necessary.

p0020For an electrical connection, a power purchase or data acceptance facility 5 is arranged opposite to a slave housing 6 in such a way the current or data transmitter device 1, that magnets or magnetic bodies 7, which are arranged in the slave housing 6, the magnet bodies 4, which are disposed in the transmitter housing 2 , opposite. When the magnetic body 7 are formed as magnets, and the magnet body 4 as the iron cores it is not necessary to pay attention to an opposite polarity. If the magnetic body 4 are also designed as magnets, it must be ensured that each oppositely directed poles are arranged opposite. To enhance the magnetic force, the magnets can be covered 7 additionally with an iron shell 8 so that there is a magnetic force increase. Such configurations of magnets are well known, which is why not describe all of it here.

p0021For simplicity, hereinafter only of a power supply device 1 and discussed a current collection equipment. 5 Of course, the two are also processing for data transfer in the sense of Datengebereinrich- and suitable a data acceptance facility.

p0022With magnetic bodies are generally magnets, referred magnetizable parts or magnetic parts that respond magnetically under the influence of a magnet. It is only essential that the magnetic body 4 of the current transmitter unit 1 and the current collection means 5 cooperate such that a magnetic holding force results on both parts by a magnetic field.

p0023The current collection device 5 is also provided with contact elements 9 in the form of surface contacts, which are arranged in the slave housing 6 so together that they correspond to the contact elements 3 of the current transmitter unit 1 are arranged oppositely in a compound of the power supply device 1 to the power take-off device. 5

p0024Figures 1 and 2 show the position just before making contact with the power supply device 1 to the power take-off device 5, thus nearing a contact connection between the contact elements 3 and 9. FIG. The contact elements 3 of the power supply device 1 are arranged in a grid-like configuration in the form of a grid-like skeleton 10 in its recesses. The rasterformige skeleton 10 has a meandering shape with rectangular turns, the contact elements 3 inserted respectively in a meander or a recess between two ribs 11 and 12, preferably clamped, be. Due to the meandering shape gives each to the next meander to the next contact element 3 according to the back, a gap 13, through which a movement of the contact elements is given. 3 In the front meanders that are 5 to face the current collection equipment, the contact elements 3 are clamped.

p0025In addition, for better guidance, however, by giving elasticity, the contact elements to be 3 each surrounded in the front section of an elastic sheath 14, which extends to just before the contact surfaces 15 of each contact element. 3

p0026The resilient sheath 14 may, for example up as plastic by injection molding or be introduced. Of course, the elastic sheath can also be applied in other ways, such as are in a prefabricated manner, and then introduced into the plastic in accordance with the contact elements. Here, too, any length of the grid-like skeleton formed in this manner are possible.

p0027The rasterformige skeleton 10 is not shown in detail, for example by gluing, with a press bridge 16 connected on its back. Instead of a grid-like skeleton, other configurations may be provided, of course, within the scope of the invention. It is only essential that a plurality of contact elements 3 are arranged in a grid pattern in an elastic envelope.

p0028The pressing bridge 16 may be elastic and slightly concave form of a rubber bridge and arranged in accordance with the encoder housing 12 between the two magnetic bodies 4, which extend over the entire length of the grid-like skeleton 10th

p0029The elastic sheath 14, the air gaps 12 and the pressing bridge 16 a safe area contact for all contact elements 3 with the contact elements 9 of the current collection means 5 is reached when connecting the power supply device 1 to the power take-off device. 5 The elastic covering 14 may also provide a moisture- or watertight connection. It also serves as a brace for the contact elements 3 at maintaining elasticity.

p0030As can be seen, this is independent of the number of adjacently arranged contact elements 3 and 9 respectively.

p0031In the present embodiment, the contact elements 3 of the power supply device 1 have been described as resiliently arranged in the grid-like skeleton 10th Of course, it is clear in the context of the invention that, alternatively, the current collection equipment 5 with corresponding elastically arranged contact elements 9 may be provided, while the contact elements 3 of the power supply device 1 fixedly disposed in the transmitter housing 2 ■ are. It is also possible, all contact elements 3 and 9 e- store lastisch in grid-like skeletons 10th

p0032As. 2 is seen from the Figure, however, the contact elements 9, as well as the contact elements 3 may be formed in the shape of thin discs with lateral extensions 17th then takes place via the lateral extensions 17 via feed and discharge lines 18, the power supply or power forwarding to a consumer, not shown.

p0033The rasterformige skeleton 10 may be formed of a resilient plastic part. For the contact elements 3 and 9 can be brass parts, silver possibly, to use as simple stampings.

p0034For precise mechanical feeder or connecting the power supply device 1 to the power take-off device 5, the power supply device 1 may be provided with one or more cone-like recesses 19, respectively, a magnetic body 4 is at the lower end. Conversely, the current collection equipment to 5 one or more cone-like extensions 20, which are adapted to the cone angle of the cone-like recesses 19th In each cone-like extension 20 are each a magnetic body is 7. For e- lektrischen connection, the conical expansions 20 are respectively inserted self-centering in the cone-like recesses 19, wherein at the end of introduction of the magnet body 4 and 7, on one another and thereby the contact connections between the contact elements 3 and 9 static bil and securely. Through this design a "blind" contact with the contact elements 3 and 9 achieved without possibility of error in practice.

p0035When very high currents are to be transferred, you can connect two adjacent contact elements 3 by a conductive contact bridge 21 together (see dashed representation in Fig. 1). The same shall apply for the corresponding function of the contact elements 9. A contact bridge 21 can also be used for cases in which a common input current to two (or more, with longer contact bridges) same output currents to or forwarded vice versa.

p0036Another security against faulty connections or contacting of mismatched power sensor devices 1 with collection devices 5 is achieved when the magnetic bodies 4 and 7 are "coded" formed. "Encoding" with formed is meant that each magnet body is composed of a plurality Einzelmagnetteilchen different polarity, wherein the opposite magnetic bodies 7 and 4 respectively arranged with opposite polarity. Such a coding example is shown in WO 01/03249 AI in Fig. 3. Also in EP 0573471 (10.12.94) so ​​coded magnets are described. In this way, a contact connection can be made only when the correct coded magnets collide.

p0037The embodiment described above is described in combination with the magnetic bodies 4 and 7. FIG. Of course, the magnetic body 4 and 7 can also be omitted if necessary and for a placement of the power purchase may siphoning device or data acceptance facility to the electricity or Datenge- connect respectively. Holding force between the two bodies are carried out in other ways, such. B. Locks or catches.
