Definitions

  • the invention relates to an electrical connection device, in particular for the arrangement between the steering wheel and steering column switch module of a motor vehicle, with a fixed housing part and a rotatable housing part, each carrying a terminal unit and at least one spirally wound, each end connected to the terminal units enclose flexible electrical conductor which is guided in a direction-reversing loop within the housing.
  • Connecting devices of this type are used in particular for the production of electrical connections between a power source and arranged in the steering wheel bowl gas impact protection device or steering wheel switches of motor vehicles.
  • a conductor arranged between the stator part and the rotatable rotor part has a length such that it can follow the steering deflection amounting to approximately three revolutions on both sides, wherein the flexible conductor emerges from a middle position in one direction until it engages during the steering wheel deflection on the stator part widens outwards and in the other direction contracts until it rests against the rotor part inwards.
  • the EP 0 556 779 B2 discloses an electrical connection device comprising an inner housing and an outer housing consisting of two relatively rotatable components.
  • the connecting device has a flexible and spiral-wound transmission medium which is accommodated in a space formed by the two housing parts.
  • the transmission medium includes inner and outer ends fixed to the inner and outer casings, respectively, and inner and outer end portions extending in opposite directions from each other around the circumference of the inner and outer casings such that between the inner and outer end portions Cable movement turning section is formed, in which the direction of movement of the transmission medium turns.
  • there are a plurality of flexible cables including at least one transmission cable serving as a transmission medium and at least one non-transmission dummy cable.
  • Each of the cables has its own inner and outer ends fixed to the inner and outer casings, respectively.
  • Inner and outer end portions of the cables extend in opposite directions from each other around the circumference of the inner and outer housings so that between the inner and outer end portions at intervals with each other spaced cable movement turning sections are formed. Furthermore, the inner and outer end portions of the cables are spaced from each other.
  • the object is achieved in that at least one further spirally wound, flexible electrical conductor is provided, which is connected to the terminal units and which is guided in a direction-reversing loop within the housing.
  • the transmission of a plurality of signals with high security is ensured in the case of the so-called short-band technology connecting device.
  • the wiring of the two conductors for example, parallel to each other, that is, redundant, or different current paths of the conductors contact different terminal contacts, according to which the number of signals to be transmitted, for example between an electrical system of a motor vehicle and a steering wheel, compared to the use of a conductor at the same height Connecting device is increased.
  • the further conductors are wound and connected in parallel to the first conductor.
  • a total of three conductors are available, which are clamped parallel to the first conductor to the connection units, after which a relatively high degree of transmission reliability is ensured.
  • the direction-reversing loops of the conductors are arranged uniformly spaced from one another in the housing.
  • the first conductor is welded to stamped bars of the terminal units.
  • the second conductor is held on plug pins in the welding region of the first conductor and has a clamping part which is held by a fixing part of the connection unit.
  • the fixing part comprises guide elements for ensuring the electrical contacting of the first conductor and the second conductor with the associated stamped grid.
  • the second conductor may be held without the clamping part of the fixing part to the associated attachment unit.
  • the third conductor and the fourth conductor are held one above the other on each socket pin, the third conductor contacting the corresponding punched grid and the fourth conductor contacting the third conductor by contact.
  • the electrical contact of the second, third and fourth conductors is achieved by a plug, press, welding, Soldered or glued connection made either with a corresponding punched grid or current paths of the respective adjacent conductor.
  • the electrical connection device comprises a fixed housing part 1 and a rotatable housing part 2, each carrying a terminal unit 3, wherein the connection contacts 4 having terminal units 3 are coupled to a stator with a vehicle electrical system of a motor vehicle and the other rotor side with steering wheel side devices.
  • a plurality of current paths 6 comprehensive conductors 7, 8, 9, 10 spirally wound and in direction reversing loops 11 within led the housing 11, wherein the loops 11 of the conductors 7, 8, 9, 10 circumferentially evenly spaced from each other in the housing are arranged.
  • the first conductor 7 is in each case welded to the terminals 4 comprehensive stamped gratings 12 of the terminal units 3.
  • the second conductor 8 is held in contact with its free ends by a respective fixing part 13 of the terminal units 3, the corresponding punched grid 12.
  • the third conductor 9 and the fourth conductor 10 are arranged one above the other, wherein the fourth conductor 10 via the other conductor 7, 8, 9 contacts the stamped grid 12.
  • locking pins 14 are provided.
