Definitions

  • the invention relates to a method for producing a control strip according to the preamble of claim 1.
  • Control strips of this type are known, for example as a contact strip, which can control several injectors in the network only by means of two current-carrying cables, in EP-A-306 739, which forms the closest prior art. If you want to use such contact strips, for example for the individual control of injection nozzles of multi-cylinder internal combustion engines, it is disadvantageous that a great deal of cables, which would be necessary for control, are in the way during assembly and maintenance.
  • this object is achieved in that a method for producing the control strip according to the Features of claim 1 is created.
  • a control bar 1 made of plastic which has both a fuel injector receptacle 2 as a multifunctional part, and which simultaneously controls the injection valves mentioned with the aid of conductive elements 3, also serves as a protective cap for the fuel valves to be provided in any number, for example on a plastic fuel pipe , whereby seal 4 ensures high operational reliability of the electrical parts and prevents contamination and resulting leakage currents.
  • the control strip 1 which is manufactured in a compact plastic construction, enables one-hand operation with the aid of the one plug strip 5 during maintenance and assembly and thus the replacement of the injection valves with the other hand.
  • the injectors are floating to ensure that they function properly.
  • the larger cross section of the conductive elements 3 guarantees lower voltage losses.
  • the conductive elements 3 are first provided with assembly aids 6.
  • the assembly aids 6 are removed again before the control strip 1 is finished.
  • the control bar 1 is equipped with a centering device 7 for one-handed installation.
  • the electrical connection to the injection valve receptacle 2 is made in the application example via electrical contact pins 8, in connection with either flexible strands 10 or spring elements 11.
  • control strip 1 with all its functions represents only a single part.
  • the conductive elements 3 are electrically insulated by the plastic housing 9.
