Definitions

  • the invention is based on a contact strip according to the preamble of claim 1.
  • a contact strip is already known, the connector housing of which is rotatably mounted about its central axes.
  • the plug housings with the first electrically conductive contact elements arranged therein carry out dynamic self-movements relative to the second electrically conductive contact elements of fuel injection valves, which lead to undesirable wear on the contact elements.
  • WO-A-91/12 425 which falls under Article 54 (3) EPC, has already proposed a contact strip which serves for the joint contacting of several electrically excitable units of internal combustion engines which are jointly mounted in a fuel distributor piece.
  • Plug housings with first electrically conductive contact elements are arranged on the contact strip housing and can be connected to second electrically conductive contact elements of electrically excitable units.

  • the radial and the axial The game that the connector housings have in the state mounted on the electrically excitable units with respect to the contact strip housing leads to the fact that the connector housings perform dynamic self-motions with respect to the contact strip housing and with respect to the electrically excitable units during operation of the internal combustion engine. These inherent movements also move the first electrically conductive contact elements fastened in the plug housings by means of clipping in relation to the second electrically conductive contact elements of the electrically excitable units. This process results in the risk of excessive wear on the contact surfaces of the first electrically conductive contact elements and the second electrically conductive contact elements, which can lead to the premature failure of the assembly consisting of contact strip and electrically excitable units.
  • the contact strip according to the invention with the features of claim 1 has the advantage of effective damping of the dynamic natural movements of the individual connector housings compared to the contact strip housing and compared to the electrically excitable units and thus the movements of the second electrically conductive contact elements of the electrically excitable units compared to those with the second electrical To enable conductive contact elements interacting first electrically conductive contact elements of the connector housing. This results in particularly low wear of the first electrically conductive contact elements and the second electrically conductive contact elements, in particular of fuel injection parts, in the area of their contact points.
  • the damping elements of the contact strip according to the invention allow the mobility of the plug housing when mounting the contact strip on the electrically excitable ones Units or the electrically excitable units connected to one another by means of the contact strip to the internal combustion engine, so that problem-free compensation of the shape and position tolerances and low-force joining are possible.
  • a damping element is arranged between a bottom end face of the bottom of the contact strip housing facing the plug housing and each plug end face of the individual plug housing facing the bottom.
  • a damping element is formed on a shoulder of a stepped through bore of the plug housing, which interacts with a central elevation of the bottom of the contact strip housing.
