Definitions

  • the invention relates to a planar filter for connectors with a Multitude of signal lines to be connected arranged in rows and columns, with a carrier for each of these signal lines an opening and in the area of this opening for each of these signal lines a capacitor with a first coating, connected to the assigned signal line, a second covering, connected via the conductive housing with ground, as well as a layered dielectric between the first and second covering, in which in each of the openings of the planar filter, a contact insert with at least two contact fingers soldered to hold the connector pins and with a extending into the opening, the first covering of the associated Capacitor is electrically connected, the connecting pins electrically via the contact fingers with that of the respective signal electrode associated first coating of the capacitors can be connected, and two opposite edges of the planar filter as conductive side areas connected to its ground electrode trained and with the metallic housing of the connector Ground are connectable.
  • Planar filters and seals are used to make a filter connector inserted into the connector housing; the individual capacitors of the planar filter are over on the outer edge of the planar filter attacking earth springs with the connector housing for manufacture the earth connection and via spring clips for the contact pins with the connecting pins inserted into the lead-through openings connected to produce the signal line derivatives. Furthermore, it is difficult to find the ones necessary for effective filtering To accommodate capacities on the substrate of the planar filter, because in the known arrangements each filter capacitor the assigned Signal line surrounds, being in the immediate vicinity of the signal line is an annular surface in which the mass coating, because of the necessary insulation is not routed to the signal line, is missing, so that this area cannot contribute to the capacity.
  • the object on which the invention is based is derived from this, after which a planar filter for connectors are proposed should be sufficient capacities for narrow signal lines for the individual capacitors surrounding the signal lines and inserted into the connector without a solder connection can be, so that it with press-fit pins in plastic parts connected and also in existing ones with a connector provided connectors can be used.

  • dumbbell or diabolo form have a preferred axis and are nested one inside the other, that the preferred axes of adjacent capacitors are crossed, the coverage area is (relatively) enlarged with the same space requirement, and with it the capacitance of the capacitors.
  • these structures are advantageous as double-T formed, being in the middle of the connecting the two end webs Center bar forms the preferred axis, in the middle of which Implementation is arranged for the associated pin.
  • each contact insert has a sleeve that as in the Opening for the passage of the connecting pins can be used in a form-fitting manner Soldering sleeve is formed, with which in this opening extending into it the first covering associated with the signal electrode Capacitor can be soldered and electrically connected by soldering is. This training creates an assignment that is in each of the openings can be used.

  • These features also allow a subsequent Equipping connectors with planar filters equipped in this way. Through these resilient contact inserts, the Force path from pen to filter holder interrupted, which is a higher Security against major accelerations or decelerations offers occurring forces.
  • the resilient contact fingers make soldering to the connection pins superfluous, with them also the insertion due to dimensional deviations not bothered.
  • the resilient contact inserts also provide electrical perfect contact between the pins and the associated coatings of the capacitors, so that both influences do not represent an obstacle to retrofitting. Let it go solder the sleeves into the feedthrough openings as the planar filter thermally resilient and at this stage of manufacture is still separated from the connector to be equipped. Despite this Solder the contact insert into the lead-through opening of the The benefits of filter carriers remain as they interact with the pins Contact fingers remain unaffected.
  • Each of the contact inserts advantageously has a sleeve, of which from conically tapering contact fingers in essentially extend in the axial direction.
  • the contact insert particularly has for clamping flat pins two with the contact pin cooperating contact fingers that each other are arranged opposite each other. With these lying opposite arranged contact fingers the connector pin interacts so that he pushes them apart and is held by clamps, the clamping forces making the contact.
  • terminals round pins provided three contact fingers that covered an angular distance of 90 ° to the circumferential angle of the sleeve or have 120 °.

  • the Contact fingers are evenly distributed over the circumference of the sleeve, which leads to an angular distance of 120 °. Clamp the contact fingers can be both with round diameter pins, however pins of other cross-sectional shapes also jam, whereby the arrangement of the contact fingers adapted to the cross section of the pins becomes.
  • the contact fingers are not at an angular distance of 90 ° evenly distributed over the circumference, but it forms one Gap so that one-sided pressure is exerted on the connector pin becomes.
  • These arrangements are also used to ensure that the sleeve is provided with an axial gap, the one between the middle two contact fingers is arranged, or the other arranged in such a way is that the two neighboring contact fingers from him have an angular distance of 90 ° and the third of the contact fingers is diametrically opposed to it. This advantageous in the middle between two of the contact fingers the sleeve receives the resilient clamping action, which is the introduction of the Relieved sleeve in the lead-through opening.
