Definitions

  • the invention relates to a multipole connector with a housing provided with at least one conductive shell, through which lines, in particular digitized signals, run and in which a planar filter is arranged on a base plate, with capacitors provided for at least some of the signal lines, which are formed by a on the base plate applied base electrode, on which a dielectric layer and on which in turn a counter electrode is applied, wherein one of the electrodes, formed continuously as a ground electrode, divided with the housing and the other of the electrodes into individual signal electrodes, conductively connected to the signal lines and wherein the base plate and the dielectric layer and at least one of the electrodes have cutouts for the passage of the signal lines.
  • Multipole connectors are used in electronics, in particular in data processing, to transmit signals from one electronic unit to another, e.g. from a first computer to a second computer.
  • the signals are transmitted as pulses with a (relatively) high pulse train via the cables connected to the devices, this transmission being disturbed by the computer's pulse trains with pulse edges that correspond to even higher frequencies and are much higher in the MHz range, so that the range of the transmission is reduced particularly via parallel interfaces.
  • the interference fields in the environment also contribute to the interference, the electromagnetic interference fields, more or less attenuated by shielding measures, also cause interference signals that lead to errors in the signal transmission.
  • multipole connectors In order to eliminate these interferences, in particular the internal interferences coming from the device, multipole connectors have already been proposed, for example in US Patents 2,841,508, 3,200,355, 3,447,104, 3,538,464 and the French publication 78.10242.
  • a planar filter essentially formed from capacitors is installed in the multipole connector, the capacitors being connected from the signal line to the ground electrode and representing low-pass filters.
  • a ceramic carrier is provided with a first electrode, which is electrically connected to the housing, to which an insulating layer is applied, which forms the dielectric of the capacitor, and which in turn has a counter electrode which is conductively connected to the signal line is applied.
  • Such a connector covering the preamble of claim 1 is known from EP-A-0 123 457.
