Definitions

  • adapter plugs - inserted between plug and mating device - for filtering interference signals from signal lines connected to the plug are known.
  • adapter plugs require more space and are only available for a limited number of connector types, e.g. for D-sub connector.
  • connectors with integrated filter functions are known, in which, however, a subsequent change or adaptation of the filter properties is not possible.
  • the invention is based on the object of shielding device interfaces against interference signals and in particular filtering or suppressing interference signals in the device interface guided signal lines while maintaining an adaptation of the filter properties that is possible at any time.
  • the object is achieved by a filter plug-in device according to the features of the preamble of claim 1 by its characterizing features.
  • the essential aspect of the filter plug-in device according to the invention for a holding plate with inserted contact pins, which have at least one earth potential surface and which are guided vertically through the holding plate, lies in the fact that at least one guide element, which has a plurality of through openings for the contact pins and is adapted to the contact pins, for receiving plugs the contact pins guided through the holding plate can be plugged in and that at least one filter element, which has at least one connecting element, is arranged between the holding plate and the attached guide element and has a plurality of through openings for the contact pins and is adapted to the contact pins.
  • the guide element is designed such that when the guide element is plugged on, the at least one connection element of the at least one filter element is pressed onto the at least one earth potential surface of the holding plate, and thus the at least one connection element and the at least one earth potential surface are electrically conductively connected.
  • a major advantage of the filter plug device is that for the filtering of interference signals from signal lines connected to contact pins of a holding plate, the use of conventional adapter plugs which have a high space requirement can be dispensed with, and filter circuits with the smallest space requirement can be implemented on the holding plate.
  • the filter properties of the filter circuits can advantageously be changed at any time.
  • connection elements which also act as spring elements can be configured - claim 5 -, a direct connection from a filter element to the at least one ground potential surface of the holding plate is established, whereby an earth potential connection within the plug device can be dispensed with and additionally the shielding effect of the filter element itself is improved.
  • FIG. 1 and 2 show schematically a partial cross section through a filter plug-in device according to the invention for a holding plate VP having a plurality of earth potential areas GND with a plurality of contact pins KS standing vertically thereon, wherein in FIG. 1 and 2 only a part of the contact pins KS pressed through the wiring plate VP is shown.
  • the holding plate VP is advantageously designed as a wiring plate or printed circuit board.
  • the contact pins KS are, for example, a component of a plug connector SV according to DIN 41612, the contact pins KS of the plug connector SV being pressed through the wiring plate VP and thus the plug connector SV being in contact with the wiring plate VP.
  • interference radiation or interference signals are leading via the plug connector SV Signal lines - not shown - connected to the contact pins KS.
  • two cuboidal filter elements FLT1.2 which have several through openings adapted according to the arrangement of the contact pins KS, are pushed or plugged onto the contact pins KS, the end faces of the cuboidal filter elements FLT1.2 lying opposite one another and thus the two filter elements FLT1 , 2 are arranged positively.
  • the contact pins KS of the wiring board VP are each guided through a through opening of a filter element FLT1, 2 and electrically conductively connected to the respective filter element FLT1.2 by spring clips or spring plates FD arranged in the through openings.
  • the two filter elements FLT1.2 can be implemented, for example, by a hybrid filter or by a low-pass planar filter in thick-film technology for filtering or suppressing interference signals that are brought in via the signal lines. Furthermore, the two filter elements FLT1.2 on the long sides have a plurality of connection elements or contact plates AE, through which one or more filter circuits integrated in the filter elements FLT1.2 - e.g. C filter circuits with a capacitance of, for example, 1200 pF for realizing attenuation values of more than 50 dB in the range from 300 to 700 MHz - with a required mass - for example with a ground potential surface GND arranged on the wiring board - can be connected.
  • the connection elements AE are advantageously designed as spring elements attached to the longitudinal sides of the filter elements FLT1.2 and connected to the integrated filter circuits - with spring action in the plugging direction.
  • a correspondingly designed contact pin KS which is guided through the through openings of the arranged filter elements FLT1,2, is approximately form-fitting, that is to say, it is approximately form-fitting to the arrangement of the two rectangular filter elements FLT1,2 adapted and also having through-openings guide element FR - also referred to as a guide frame - for better reception or guidance of plug-in elements pushed on or plugged on, with the contact pins KS protruding through the through-openings of the filter elements FLT1.2 also through the openings of the attached or pushed on guide frame FR are guided.
  • the guide frame FR has a recess which is adapted to the form-fitting arrangement of the two filter elements FLT1.2 and which is designed such that, when the guide frame FR is fitted, the contact plates AE on the long sides of the two filter elements FLT1.2 onto the earth potential surfaces GND of the wiring plate VP are pressed, and thus the ground connections of the filter circuits integrated in the filter elements FLT1,2 are electrically conductively connected to the ground potential surfaces of the wiring board.
  • the guide frame FR can be locked or fastened with the aid of laterally arranged fastening units BE to counter-fastening units GE correspondingly arranged in the wiring board VP - for example by means of a detachable rivet connection.
  • the guide frame FR can be firmly connected to the wiring board VP, and thus a safe ground connection can be established or guaranteed between the filter circuits implemented in the filter units FLT1,2 and the ground potential areas of the wiring board VP.
  • a handle shell GS having a counter gene connector GV and adapted to the shape of the guide frame FR can be pushed over the guide frame FR, wherein in the pushed-on state of the handle shell GS the contact pins KS guided through the through openings of the guide frame FR in the correspondingly arranged counter connector Insert the GV and thus an electrical connection between the ones connected to the contact pins KS of the wiring board VP Signal lines and corresponding signal lines connected to the mating connector GV - not shown - is produced.
  • the inside of the handle shell GS is lined with an external and internal interference-repellent metal layer MS or metal shield.
  • the metal shield MS When the handle shell GS is pushed onto the guide frame FR, the metal shield MS according to FIG. 2 is connected in an electrically conductive manner to the earth potential surfaces GND of the wiring board VP via connecting elements MA, as a result of which a secure ground connection is established between the wiring board VP and the metal shielding of the handle tray GS thus the electrical components KS, FLT1.2, GV, FR enclosed by the GS grip shell are optimally shielded against the occurrence of starch radiation.
  • the handle shell GS can be locked in the state pushed onto the guide frame FR with the aid of two fastening units WB arranged on the end faces of the handle shell GS on the fastening units BE of the guide frame FR or on the counter-fastening units GE of the wiring board VP in order to ensure a secure electrical connection between to ensure the contact pins KS of the wiring plate VP and the mating connector GV arranged in the grip shell GS and a secure ground connection between the ground potential surfaces GND of the wiring plate VP and the metal shield MS arranged in the grip shell GS.
  • the grip shell GS is advantageously fixed to the guide frame FR or to the wiring plate VP with the aid of a screw connection.
