Definitions

  • the invention relates to an electrical contact device for forming a conductive connection between connection bodies via a plurality of contact bodies according to the preambles of claims 1, 3, 7, 16, 20 and 24.
  • Contact devices of the generic type are e.g. known from DE-A1 3048054 and DE-A1 3116002.
  • the contact devices are used in particular in electrical plug connections as a resilient intermediate member. In the case of a plug-socket connection, the contact device can be fastened either in the socket or on the plug. Another application is the electrical contacting of busbars. At the overlapping connection points of busbars, the contact devices are arranged between the rail sections pressed against one another. Furthermore, the contact devices can be used in sliding devices as sliding contacts, wherein they are attached either to the fixed or to the movable contact bodies of the switching device.
  • connection devices are intended on the one hand to ensure reliable mechanical contact between the connection bodies, even after a long period of use and possibly after a large number of plug-in operations, and on the other hand to have the lowest possible electrical contact resistance between the connection bodies to be connected.
  • both conditions are influenced by a suitable choice of material for the conductor parts and by suitable dimensioning of the contact pressure.
  • connection bodies In addition to the lowest possible electrical contact resistance between the connection bodies, such contact devices are intended to ensure reliable mechanical contact between the connection bodies.
  • the first sub-problem ie the reduction of the transition resistance
  • the second sub-problem namely the safe mechanical contact or the contact pressure to be applied by the spring.
  • the manufacturing outlay of the contact device should in particular also be reduced.
  • the decisive advantage of these measures lies in the optimal exploitation of the good spring properties of the spring material used and the much larger tolerance ranges for the contact bodies made possible, and the surprisingly high safety and reliability and uniformity of the desired contact pressure despite the increased dimensional tolerances.
  • the manufacturing outlay for the training described is relatively low compared to the known designs.
  • the proposed training requires few simple and easy to master manufacturing steps.
  • the electrical contact device 1 shown in FIGS. 1A to 1D consists of a spring band 2, into which contact bodies 3 arranged in the manner of a blind are inserted.
  • the spring band 2 is provided with receiving slots 4.
  • the contact bodies 3 are provided from both sides with inclined locking grooves 5. These grooves correspond to the thickness of the spring band 2, so that the contact bodies 3 can be pressed in in a latching manner (cf. FIG. 1D).
  • the locking grooves 5 are inclined at an angle ⁇ relative to the level of the contact bodies 3 in order to implement the desired angle of inclination thereof relative to the plane 7 of the spring band 2.
  • the amount by which the contact bodies 3 are inclined with respect to the spring band plane 7 can in practice be between a few degrees of angle and approximately 45 °. An inclination of approximately 40 ° has proven to be particularly advantageous.
  • the spring band 2 can consist of spring steel or spring bronze, for example of Cu / Be bronze.
  • An electrically highly conductive material is preferably used as the contact material. It should be noted that the height of the contact bodies 3 is independent of the mutual spacing between them along the spring band 2. This means that it is possible to bridge larger tolerances between two connecting bodies to be electrically connected to one another by appropriate choice of the contact height without the number of Contact body, based on the length of the spring band, would have to be reduced. The desired high current carrying capacity remains fully guaranteed.
  • the spring band 2 can be composed of two sub-bands 2a, 2b which are connected to one another. This has the advantage that the edges 6 of the slots 4 do not have to be bent away (as shown in FIG. 1D) during the assembly of the contact bodies 3. Rather, in this case, the sub-bands 2a, 2b can be pushed laterally into the locking grooves 5 and, if necessary, subsequently connected to one another.
  • the spring band 16 is flat.
  • the contact bodies 8 to 11 are lined up at a distance a at an angle ⁇ relative to the spring band plane on the spring band 16.
  • the angle ⁇ is preferably 40 °. If, under the influence of a contact pressure that is exerted on the electrical contact device between a first connection body 200 and a second connection body 210, the gap D is narrowed to the dimension D1 (FIG. 2B), the contact bodies 8 to 11 inevitably take a more inclined one Position. This means that the angle ⁇ decreases.
  • the contact bodies 8 to 11 and the spring band 16 assumes a corrugated shape, as is shown for the selected example in FIG. 2B.
  • the described device also permits larger adjustment angles of the contact bodies without any problems and under largely constant spring pressure of the contact bodies relative to the connection bodies 100 and 210.
  • FIG. 2B shows in the area of the two outer left contact bodies a particularly advantageous, because simple and reliable, spacer 16a in the form of a hose section pulled over the spring band 16.
  • This preferably consists of soft-elastic or soft-plastic material and is therefore adaptable on its end faces with respect to the variable inclination of the adjacent contact body. This also results in a desired increase in the contact pressure, which can be influenced by suitable dimensioning and choice of material.
  • spacers are particularly advantageous for designs with spring wires (see Fig. 3A).
  • Resilient spacers that are at least partially elastically deformable in the axial direction are expediently inserted under a certain axial compression between the contact bodies. This can be easily achieved when assembling with alternating rows of contact bodies and spacers on the spring band or the spring wire by pressing the line together with subsequent locking or closing the band or wire ends.
  • the axial preload of the spacers results in a play-free, but flexible and adaptable position securing of the contact bodies in the operating state.
  • This further favors the shape of the plate-like contact body with simple, prismatic or cylindrical recesses running in the direction transverse to the plate plane for the passage of the spring band or spring wire. This has considerable advantages in terms of production technology, without impairing the backlash-free or low-backlash securing of the contact bodies.
  • a modification of this embodiment is indicated in the right part of FIG. 2B.
  • a flexible securing of the position of the contact bodies is achieved by means of a hose 16b which surrounds the spring band or the spring wire and extends continuously over a plurality of contact bodies and is radially elastically and / or plastically compressible.
  • the insertion of the spring element with hose into the recesses can still be carried out comfortably during assembly.
  • the radial one Compression of the tube sections located within the contact body recesses provides a secure, force-fitting or, due to the displacement of tube material into the adjacent areas outside the recesses, even positive, but nevertheless flexible, positional securing of the contact bodies.
  • hose sections can also be inserted as spacers between the contact bodies.
  • hose profile does not necessarily have to be closed on the circumference for the present applications. Rather, all suitable hollow profiles are considered, e.g. also U profiles. It is also understood that such a spacer - as is not particularly shown in FIG. 2B - is generally to be extended over a larger number or over a whole series of contact bodies.
  • FIGS. 3A to 3D show exemplary embodiments for suitable contact body shapes.
  • the contact body 8 according to FIG. 3A has two bores 12, which are inclined relative to the contact plane 17 (cf. FIG. 2A) and are used for the passage of spring wires.
  • FIG. 3B shows the example of a central slot 13 that is inclined relative to the contact plane 17 (see FIG. 2A) for receiving a spring band.
  • FIGS. 3C and 3D show contact bodies 10, 11 which have lateral recesses 14, 15 for inserting spring wires (FIG. 3C) or spring bands (FIG. 3D). These recesses 14, 15 can be easily closed by compressing or squeezing after the insertion of the spring elements.
  • FIG. 4 shows an example with a multi-corrugated spring band or spring wire 16.
  • Such embodiments contribute to a further extension of the spring area.
  • FIGS. 5A to 5F show an electrical contact device, the contact bodies of which are formed by pockets 21 made of a material with high electrical conductivity, such as copper, which are each arranged on a web 20 of the spring band 18 and completely encompass it (cf. 5A; 5E). Recesses 19 are punched out of the spring band 18, resulting in webs 20 (cf. FIG. 5C). These are opposite the spring band level 31 rotated by an angle (see FIG. 5A). It is thereby achieved that the webs 20 can spring like a torsion relative to the edges 18a of the spring band 18.
  • the assembly of the pocket-shaped contact bodies is very simple: they are pushed over the assigned webs 20 and their end regions 21a are then connected in a form-fitting or material-locking manner, for example with the aid of spot welds 22 (cf. FIG. 5D; 5E).
  • the fastening problem can also be solved in such a way that the end regions 21a mentioned are claw-shaped and brought into engagement with one another. In this case, it may be possible to dispense with integrally bonded lead connections.
  • 5B a section of the electrical contact device with two mounted pockets 21 is shown in perspective.
  • FIGS. 6A to 6E show an electrical contact device, the contact bodies of which are formed by windings 29 made of a material with high electrical conductivity (which in turn can be copper), which are each connected to two tongues 25 or possibly only held in mutual contact , 27 are arranged, which belong to different spring bands 24 and are pushed into the winding 29 from opposite sides (cf. FIG. 6B). Accordingly, two tongues 25, 27 are completely surrounded by a winding 29 (cf. FIG. 6B).
  • the electrical contact device also has at least two spring bands 24 lying next to one another, cutouts 26, 28 are punched out of each spring band 24, which results in tongues 25, 27 which are integrally connected to a connecting strip 24a (cf. FIG. 6C).
  • the tongues 25, 27 are rotated by an angle with respect to the spring band level 31 (cf. FIG. 6A). This in turn ensures that the tongues 25, 27 can spring like a torsion relative to the connecting strip 24a connected to them.
  • the torsion axis and the axis of symmetry of each tongue 25 can coincide or the former can be eccentric with respect to the latter (cf. tongue 27 shown in broken lines in FIG. 6C).
  • the winding-shaped contact bodies are assembled by inserting the associated tongues 25, 27 (cf. FIG. 6D).
  • the individual tongue pairs 25, 27 are then connected to one another, for example, with the aid of spot welds 30. The assembly performed in this way impresses with its simplicity.
  • the winding-shaped contact bodies can be arranged in several rows (cf. FIG. 6E).
  • contact bodies used in the exemplary embodiment according to FIGS. 5A to 5F may also be in the form of a wrap, and the exemplary embodiment according to FIGS. 6A to 6E may also be pocket-shaped.
  • the webs 20 or the mutually connected tongue pairs 25, 27 can also be arranged in more than two rows.
  • connection bodies 200, 210 It is known that in particular the longitudinal edges of the contact bodies 3, 8 to 11 serve as a contact bridge to the connection bodies 200, 210. These parts of the contact bodies are subjected to particularly high loads depending on the current load between the connection bodies.
  • the contact body consists of a first and a second outer contact part 32 and a contact lamella 42, which is clamped between them and is made of a material with high electrical conductivity, the ends 43 of which protrude beyond the contact parts 32.
  • the outer contact parts 32 can consist of metal, plastic or another material having the required mechanical properties.
  • the contact lamella 42 must have good electrical properties; the mechanical properties of this lamella 42, such as sufficient strength, on the other hand play a rather minor role.
  • a copper braid for example, can be used as the material for the lamella 42.
  • the contact body is made of metal or insulating material and is wrapped with a wire 41, which consists of a material with high electrical conductivity, or with a strand.
  • the edge regions of the contact bodies are provided with an inserted contact lamella 33 made of a material with high electrical conductivity.
  • the edge areas are provided with grooves.
  • FIGS. 10A to 10C show further exemplary embodiments of contact bodies. These have resilient contact blades with high electrical conductivity.
  • the contact lamella 34 according to FIG. 10A has a U-shaped cross section and is placed over one end of the contact body.
  • the contact lamella 35 is inserted with one end in a groove 37 on the contact body.
  • the contact lamella 36 according to FIG. 10C can consist of phosphor bronze wire and, like the contact lamella 34 according to FIG. 10A, can be placed over one end of the contact body.
  • the contact lamellae 34, 35 shown in FIGS. 10A and 10B also have slots 39, as a result of which a plurality of contact regions which are arranged next to one another and are independent of one another are formed.
  • the exemplary embodiment according to FIG. 11 provides for a contact body, which consists of one on the contact surfaces Slots 39 provided circuit board. According to FIG. 12, the contact edges 40 can additionally be angled slightly.
  • connection bodies described in connection with FIGS. 7 to 11 are particularly suitable for high current loads on the contact device when used with connection bodies which, with regard to their mutual position and / or as a result of machining tolerances on their surfaces, do not guarantee that an essentially rigid one Contact body lies along its entire contact edges on the surfaces of the connection body.
  • two plate-like prismatic, dimensionally stable contact bodies 101 are arranged one behind the other in the direction parallel to the axis of cylindrical connecting bodies 100a and 100b and connected to one another by a rod-shaped torsion spring 104.
  • the latter comprises two square profile sections 104a arranged with an axial spacing and lies in aligned channels 101a of the two contact bodies 101, which have a square profile adapted to the profile sections 104a and thus produce a positive torsion connection between the contact bodies located one behind the other.
  • cylindrical rod sections 104b of the torsion spring the middle one lying between the two square profile sections 104a acts as elastic twistable spring element, while the two outer protrude beyond the end faces of the contact bodies and engage in radial slots 110a of mutual ring elements 110b and 110c of a cage-like guide device 110 formed thereby.
  • the pivot axis XX of the aligned contact bodies can shift radially relative to the axis of the cylindrical connecting bodies 100a, 100b during their pivoting movement without the risk of tilting due to tangential inclination with respect to the connecting bodies.
  • connection body In the relaxed state of the torsion spring, the two contact bodies are pivoted at right angles to one another, while when inserted between the contact surfaces of the connection bodies 100a and 100b they assume their position according to FIG.
  • the outer longitudinal edges of the contact bodies are under a pressure corresponding to the pretension on the contact surfaces of the connection bodies.
  • the ring elements 110a and 110b of the guide device 110 furthermore ensure precise axial locking of the guide bodies, so that repeated axial displacement of the connection bodies relative to one another is possible.
  • the connection body can therefore be designed in particular as a socket and plug, as indicated in FIGS. 13 and 14. For the sake of clarity, only one pair of contact bodies is shown in FIG. 13 in the space between the two connection bodies.
  • complete occupation of the available contact areas with contact body arrangements corresponding to the number of existing pairs of mutually opposite slots 110a enables contact devices of simple construction for high current loads.
  • two outer contact bodies 102 and one middle contact body 103 - all of which are designed with a profile similar to the embodiment according to FIG. 13 - are aligned with one another with their continuous square profile channels 102a and 103a.
  • a torsion spring 105 acting analogously to the previous embodiment is in turn provided with profile sections 105a and 105b which are adapted to the channel profile and are assigned to the contact bodies 102 and 103, respectively.
  • Relatively torsion-soft spring sections 109 are formed between the profile sections, the diameter of which is smaller than the smallest diameter of the profile sections.
  • the torsion springs can be made of high-strength material, for example spring steel, while an embodiment of the torsion springs according to the preceding exemplary embodiment with its torsion springs with a larger diameter allows the use of materials with a lower modulus of elasticity, for example suitable plastics which are particularly economical to process allow.
  • the symmetrical composition of the three contact bodies results in an arrangement of the contact bodies which is statically essentially in equilibrium under prestress. Nevertheless, guide pins 105c are provided at the ends of the torsion spring, which engage in slots 111b of opposite edge sections 111a of a cage-like guide device. Do not intervene in more detail. In a manner not shown here, this also gives the possibility of producing larger contact fields, e.g. also flat contact fields for connections on power rails. To increase the current carrying capacity, in the example, elastically flexible contact blades 112 are again used on the outer edges of the contact bodies 102 and 103.
  • the modification according to FIG. 18 shows the possibility of a cylindrical torsion spring rod 113 with strongly dimensioned and distinctly radially projecting profile sections 114 for the torsion coupling of the contact bodies.
  • Such a design allows particularly large force transmission surfaces between the torsion spring and contact bodies. It is therefore particularly suitable for cheap plastic torsion springs.
