Definitions

  • the invention relates to a power line connector for the electrical lead to an airbag impact protection device arranged in the steering wheel bowl of a motor vehicle, consisting of an essentially formed from a conductor strip current conductor, the ore in several concentric windings in a steering wheel.
  • Steering wheel hub surrounding the frame fixed housing and the ends of each with an inner bezw. outer connecting element are connected, of which the inner connecting element on a respectively the steering spindle.
  • the core surrounding the steering wheel hub and rotating with the steering wheel and the outer connecting element are arranged in the region of the outer wall of the housing.
  • the power line connector of this type which has become known, for example, from DE-A-30 09 109.9, in which the ends of the current-carrying line are each fixed in a housing. the connection clamp arranged in the core are held up, has proven itself essentially well.
  • a bending moment is exerted on the conductor strip, in particular in the area of the connecting terminal released by the steering wheel rotation, which leads to a bending of the steering wheel which is reset when the steering wheel is turned back into its other stop position
  • Conductor tape leads.
  • the present invention has for its object to provide a line connector in which the risk of a line break is excluded with certainty even with unlimited frequent maximum steering wheel rotation.
  • the invention consists in that at least the outer, preferably the outer and the inner connecting element is (are) formed by a rotary nipple which is held in a rotary bearing formed in the housing and enclosing an opening in the wall of the housing, the current-carrying conductor outside the Housing axially inserted into the rotating nipple and radially out of the rotating nipple within the housing.
  • the invention provides a line connector in which the current-carrying conductor is able to follow all movements resulting from the steering wheel rotation without exerting a bending moment on the conductor itself, so that the alternating bends causing the risk of conductor breakage are avoided.
  • the line connector can thus be loaded with an unlimited number of steering games without fear of impairment of the function of the gas bag impact protection device.
  • the current-carrying conductor can be formed by a one-piece conductor strip which projects through the nipple and which is placed at a loop forming an angle of approximately 90 ° and is enclosed by the nipple in the region of the loop.
  • This embodiment of the invention enables a particularly simple manufacture of the line connector while ensuring a permanent electrical connection insofar as screwing or soldering work is not required to produce the galvanic connection, rather it merely involves bending the conductor into a loop and inserting the loop into the injection mold needed to manufacture the nipple.
  • the current-carrying conductor can also be formed within the housing by a conductor strip and outside the housing by a round conductor, which are connected to one another by means of a connecting element in a position enclosing an angle of approximately 90 °, the connecting element being connected by the Rotating nipple is enclosed.
  • the rotary bearing is expediently formed by a sleeve arranged in the region of the wall of the housing and projecting through the housing base, which is provided with a slot forming a side opening against the interior of the housing and allowing the rotary nipple to rotate by a predetermined angle, the rotary nipple having a circumferential groove and the pivot bearing is provided with a shoulder projection protruding into the groove. In this way, a secure mounting of the pivot bearing is ensured while ensuring the required freedom of rotation.
  • the power line connector shown in the drawing for the electrical supply line to an airbag impact protection device arranged in the steering wheel bowl of a motor vehicle essentially consists of a current conductor formed by a conductor strip 1, which in a plurality of concentric windings in a steering wheel.
  • Steering wheel hub 3 surrounding frame 2 is arranged and the ends of each with an inner bezw.
  • outer connecting element 4, 5 are connected, of which the inner connecting element on a the steering spindle respectively.
  • the steering wheel hub enclosing and rotating with the steering wheel core 6 and the outer connecting element are arranged in the region of the outer wall of the housing 2.
  • the outer connecting element 5 is formed by a rotating nipple 7, which is held in a rotary bearing 8 formed in the housing 2 and enclosing an opening in the wall of the housing 2, the current-carrying conductor being axially inserted into the rotating nipple 7 outside the housing and inside the housing 2 is led radially out of the rotating nipple.
  • the current-carrying conductor is formed by a one-piece conductor strip 1 projecting through the nipple 7, which is laid at a loop forming an angle of approximately 90 ° and is enclosed by the nipple 7 in the region of the loop, while In the embodiment shown in FIG.
  • the current-carrying conductor is formed inside the housing 2 by a conductor strip 1 and outside the housing by a round conductor 9, which are connected to one another either by soldering or by means of a plug connector in a position enclosing an angle of approximately 90 ° are, the connection point is enclosed by the rotating nipple 7.
  • the rotary bearing 8 is formed by a sleeve arranged in the region of the wall of the housing 2 and projecting through the housing base, which is provided with a slot 10 forming a side opening against the interior of the housing and having a width that allows the rotary nipple 7 to rotate by a predetermined angle.
  • the rotary nipple 7 is provided with a circumferential groove and the rotary bearing 8 with a shoulder shoulder 11 protruding into the groove, by means of which a secure mounting and guidance of the rotary nipple is ensured while maintaining the required freedom of rotation.
