Definitions

  • the invention relates to a connecting device comprising a first and a second housing part, which are rotatable relative to one another, at least one flexible cable element between the two housing parts, which with its first and its second end section in each case spiral or on assigned contact surfaces on the first and second housing parts can be wound up and unwound helically and has a central section with a U-shaped turning area in which the winding direction reverses, as well as means for controlled unrolling of the cable element when winding and / or unwinding the contact surfaces when the two housing parts are rotated relative to each other.
  • a connecting device of the type described in the introduction can be used, for example, in a steering device for motor vehicles. There it serves to transmit electrical current (in particular signal and / or power current) from the on-board electronics of a motor vehicle fixed to the body to the steering wheel or vice versa.
  • electrical current in particular signal and / or power current
  • This allows on Steering wheel provided electrical or electronic functional elements, such as the ignition of the gas generator of an airbag unit, a steering wheel heating or electrical switches for actuating turn signals, wipers or a radio, integrated into the steering wheel and supplied with power by the on-board electronics.
  • Such a device is known for example from EP 0 556 779 B1.
  • This comprises an outer housing part which is assigned to an assembly which is stationary with respect to the rotational movement of the steering wheel, such as, for example, the steering column cladding of the steering device, and an inner housing part which is arranged concentrically with the outer housing part and which is assigned to the steering wheel and can be rotated together with it.
  • the outer and the inner housing part enclose an annular cavity in which flexible cables for the electrical connection of the outer to the inner housing part are arranged.
  • the end sections of these flexible cables are fixed to the fixed and movable housing parts and can be wound up or unwound on their inner and outer peripheral surfaces when the two housing parts rotate relative to one another.
  • the flexible cables In a central region, the flexible cables have a U-shaped turning region, in which the winding direction of the flexible cable on one housing part is reversed relative to the other housing part.
  • the radially further inside or radially further outside end sections of adjacent cables are pressed against the corresponding inner or outer contact surface.
  • the cables are thus fixed around the entire circumference at regular intervals on their contact surfaces.
  • a disadvantage of the known arrangement is that with the number of steering wheel devices usually used four connecting cables that are so far apart from each other by the four turning areas that the cables can still come off in the sections between them. This leads to collisions and friction between adjacent cables, which not only disrupts the unwinding movement as a whole, but also exposes the cables to increased wear.
  • DE 40 04 233 A1 also discloses a connecting device of the type mentioned at the outset, in which, in contrast to the vertical cable arrangement from EP 556 779 B1, the cables can be wound up or unwound horizontally.
  • DE 40 04 233 A1 describes an embodiment in which a flat cable as a whole is deformed in such a way that flat sides of its windings lying one above the other in the manner of a helix or corkscrew lie one above the other and have the same central axis. The turns therefore have the same outside and the same inside diameter.
  • the cable has a spiral shape, in which a plurality of coaxial coils are arranged radially next to one another on one and the same plane, so that the inside and outside diameters of the coils decrease or increase in the radial direction.
  • the housing parts are formed by an inner cylindrical shaft section and a plate-like upper flange which extends radially outward from the upper end of the shaft section or an outer cylindrical section which is arranged coaxially to the inner shaft section and one radially from the lower end thereof formed outwardly extending plate-like lower flange.
  • the contact surfaces for the cable elements are the mutually facing surfaces of the horizontally aligned flanges.
  • the object of the invention is to develop a connecting device of the type described in the introduction in such a way that detachment of the flexible cables and thus mutual rubbing off of detached parts is avoided and a smooth rotary movement is ensured.
  • This object is achieved with a connecting device with all the features of claim 1.
  • a preferred use for such a connecting device is described in claim 12.
  • the connecting device has a first and a second housing part, which can be rotated relative to one another, and at least one flexible cable element between the two housing parts, which spiral with its first and its second end section in each case on associated contact surfaces on the first and second housing parts - or can be wound up or unwound like a coil and has a central section with a U-shaped turning area in which the winding direction reverses.
  • a connecting device in a connecting device according to the invention, means for controlled unrolling of the cable element when winding and / or unwinding on the contact surfaces when the two housing parts are rotated relative to one another are provided, the means for controlled unrolling being magnetic and / or magnetizable regions of the cable element and / or the housing parts, which are arranged in such a way that they bring about a releasable adhesion of the end sections of the cable element to the respective contact surfaces.
  • the use of magnetic attraction forces has the advantage that they can be set so that the cable sections between the U-shaped turning areas are securely fixed and thus prevented from detaching, but that, on the other hand, the cable sections can easily be unrolled during a rotary movement. This ensures a controlled, jerk-free and smooth rotary movement, the wear of the cable sections is kept as low as possible.
  • the solution according to the invention is technically simple to implement, for example in contrast to those also known from the prior art, e.g. from US Pat. No. 5,224,871, roller cages, which are arranged in an annular cavity between an inner and an outer housing part and have the task of pressing the flexible cables against the inner or outer contact surface of the housing parts.
  • the present invention has the further advantage that the magnetic forces of attraction act not only between the contact surfaces of the housing part and the cable element lying thereon, but also with a suitable arrangement of the magnetic or magnetizable regions between overlapping cable element sections in overlapping regions.
  • a cable element in the sense of the invention comprises one or more electrical conductors which are surrounded by a sheath. If necessary, but not absolutely necessary, the conductor (s) in the sheath are additionally surrounded by an insulation material. However, a cable element in the sense of the invention also comprises one or more light guides which are surrounded by a sheath. What has been described in connection with the electrical conductors applies accordingly to light guides.
  • the magnetic and / or magnetizable areas of the cable element and / or the housing parts are formed by a sheathing of the cable element and / or the contact surface on the housing part, at least in some areas made of a magnetic and / or magnetizable material. Since in this embodiment between the casings adjacent, z. B. superimposed, cable elements magnetic attraction, the cable elements are securely fixed in the overlap areas.
  • a previously described cable element is characterized by a particularly simple structure and is simple and inexpensive to implement.
  • the magnetic and / or magnetizable areas of the cable element and / or the housing parts are formed by a coating made of a magnetic and / or magnetizable material that is at least partially applied to the cable element sheathing and / or the contact surface on the housing part ,
  • This embodiment has the advantage that impairment of the electrical properties of the cable element can be reliably ruled out since the cable itself is not changed.
  • this variant allows the use of any existing cable elements without special adaptation.
  • the magnetic or magnetizable coating is applied symmetrically to the cable element so that the magnetic forces in the area of the electrical conductors compensate each other.
  • the electrical conductors are thus in neutral fiber, which means the wear during the bending process is reduced.
  • the coating on both sides ensures that in the case of cable element sections lying one above the other, the outer magnetic layers come into contact with one another, as a result of which, with a suitable geometry of the magnetization, a high magnetic adhesive force can be achieved between the cable element sections.
  • the magnetic material comprises an elastomeric or thermoplastic material in which magnetic particles such as e.g. SrFe or NdFeB, are stored.
  • the basis for an elastomeric material is e.g. Latices, PU (polyurethane) rubber, NBR (nitrile rubber), ACM (acrylate rubber), silicones and / or FKM (fluorine rubber) in question, as the basis for a thermoplastic material PE (polyethylene), PP (polypropylene ), PVC (polyvinyl chloride), PET (polyethylene terephthalate), PEN (polyethylene naphthalate) and / or PU (polyurethane).
