Definitions

  • the invention relates to a throttle valve actuator for a Motor vehicle engine, which one with electrical energy to supplying servomotor and spatially separated from a potentiometer for determining the position of a shaft of the throttle valve Has the throttle plate with a one with supports fixed conductor bridge supported in the throttle valve actuator comprising which two rigid conductor rails for power supply of the servomotor and conductor for contacting printed conductors of the potentiometer has, and that each of the two Ladder rails and the ladder each with a pin a connector receptacle of the conductor bridge are connected.
  • Throttle valve actuator of the above type are in today Motor vehicles with so-called E-gas available and therefore known. With them the power adjustment does not take place more by mechanical coupling of the accelerator pedal with the throttle, but by electrical control commands depending from the accelerator pedal position. This leads a wiring harness into the throttle valve positioner with the potentiometer the control electronics and the servomotor with by Control electronics controlled to connect electrical energy. Problematic with such electrical connections over Cable is that it is relatively easy to break cables due to swinging can come in self-resonance. Often there is mounting also the risk of having cables between a housing and to be clamped on a lid to be placed on it. For device internal Plug connections are caused by movements in the Range of electrical connections and under the influence the temperature to contact fretting (friction oxidation).
  • a throttle valve actuator for a Motor vehicle engine which one with electrical energy to be supplied servomotor and spatially separated a potentiometer for determining the position of a shaft of Throttle has, known.
  • This throttle valve actuator has a conductor bridge of two elastic tracks to Power supply of the servomotor.
  • the invention is based on the problem, a throttle valve actuator of the type mentioned above in such a way that his required electrical connections as simple as possible designed, however, against vibrations and in one Motor vehicle occurring, high temperatures possible insensitive.
  • the Ladder rails two by injection molding in an injection mold connect generated plastic body together, which each having one of the supports.
  • the throttle valve actuator supported conductor bridge makes the laying of individual cables in the throttle valve actuator and the creation of individual, electrical connections unnecessary. This reduces the assembly effort and it can Space for such cables can be saved.
  • the inventive conductor bridge could even serve as a carrier for additional components, for example for a suppression choke, bleeder resistors, motor brushes with pigtails and the like. Over a provided in plastic breaking point can by kinking then exposed conductor pieces for tolerance compensation be used.
  • the conductor bridge can with its two plastic bodies in be produced in an injection molding process, if
  • the conductor rails along with the ladders and the pins as usable in an injection mold and there to form the Plastic body at the ends to be encapsulated insert are formed.
  • the insert can be inserted into the injection mold as a single, one-piece component are formed when it in the field of plastic body after injection molding by free distances to be removed connecting webs between having the conductor rails and the conductors.
  • Electric conductors work very well against corrosion protect and have high electrical conductivity, when you apply them with a high-gloss metal layer covers, in particular gilded or silvered.
  • coatings have a high reflectivity, so that high power is required for laser welding is.
  • this has the disadvantage that very easily through the laser beam holes in the material to be welded arise and therefore no welded connection too Come. Difficulty in laser welding through too high reflectivity can then be Avoid using the insert completely with a coated electrically conductive, high-gloss metal layer is when the terminal lugs in the range of laser light welding by embossing a rough surface exhibit. As a result, an undesirably high reflection of the laser light prevented.
  • the insert has a particularly good electrical conductivity and very low electrical contact resistance and, overall, has little tendency for corrosion when it is completely covered with silver.
  • the contacting of the servomotor is by simple Sliding the conductor bridge possible without the danger of a contact franchise, if according to another Development of the invention, the conductor rails in the actuator associated with the plastic body with two Contact post ends and the actuator two in one sharp angles against these contact posts, a clamping cutting connection enabling contact lugs Has.
  • the throttle plate actuator can also be designed in such a way that inside its housing no connectors must be done when the pins in one sealing led out of the throttle actuator, outer device connectors are arranged.
  • FIG. 1 shows a brush holder by a servomotor 1 and at a distance next to a potentiometer 2, which the position tap a throttle shaft is used.
  • Conductor bridge 3 For electrical connection of these components is used
  • Conductor bridge 3 This has two conductor rails 4, 5, which at their ends each with a two conductor rails 4, 5 common plastic body 6, 7 overmoulded are.
  • Both plastic body 6, 7 have at the bottom a support 8, 9, with which they are in a throttle plate sit up and are fastened.
  • the plastic body 7 has a connector receptacle 10 with Pins 11 to 16.
  • the two right pins 15, 16 each have one of the conductor rails 4, 5 connection.
  • From the plastic body 7 lead elastic Terminal lugs 17-20 for printed conductors 21-24 of the potentiometer 2. These terminal lugs 17 - 20 were by laser welding with the tracks 21-24 connected, with each connecting lug to increase before The roughness of their surface provided with stampings has been.
  • FIG. 2 shows the conductor bridge 3 as an individual part. To see are in the support 9 of the plastic body. 6 two upstanding contact posts 25, 26. The contact post 25 is connected to the conductor rail 5, while the contact post 26 with the conductor rail 4th Has connection. Against each of the contact posts 25, 26 is in the assembled state, not shown contact lug of the brush holder 1 at an acute angle such that the brush holder 1 from above on the Contact post 25, 26 can be postponed, the contact flags but bang up like a barb, if you wanted to pull off the brush holder 1 again.
  • FIG. 3 shows an insert 27, which the conductor rails 4, 5 with the contact posts 25, 26, the plug pins 11-16 and the terminal lugs 17-20 having.
  • Each of the terminal lugs 17-20 is connected via a Ladder 28 with one of the pins 11 - 15 electrically connected.
  • one-piece component are, for example, the conductor rails 4, 5 and the conductors 28 by connecting webs 29, 30 with each other connected. In the previously explained Figure 2 are on the corresponding places free breaks 31, 32 to recognize.
