Definitions

  • the invention relates to an electrical connector, the has at least one electrically conductive contact element.
  • Connectors are used to connect usually portable electrical consumers. For this the Connector with its trained on its connection side free end area to an electrical line connection connected.
  • the contact page its other free end area, that of a plug or socket can be designed to the electrical consumer, for example via a connector designed as a counterpart infected.
  • filters can be found in the input circuits of the devices provided or connected upstream of the device input. In both cases, connectors are suitable for this, which are equipped with the appropriate filter elements. These so-called filter connectors can be used with a Male or female connector.
  • Connectors with individual contact elements are known where a filter for electromagnetic interference firmly integrated in the individual contact element is.
  • the contact elements form a complete with the filter Component. A subsequent completion of individual contact elements with filters is practically not possible.
  • connectors with planar filters are known.
  • soldered connections do not only include elevated ones Manufacturing costs, but also represent an undesirable thermal Strain on the ceramic materials.
  • a contact element and grounding plate or Given connector housing formed rigid unit Through the solderingly firm Connection between the capacitor designed as a sleeve and the contact element inserted through the sleeve on the one hand and between the sleeve and the grounding plate on the other hand is a contact element and grounding plate or Given connector housing formed rigid unit.
  • From DE-OS 28 26 458 is a connector of the generic type kind known, the filter is built solderless. So supports a sleeve-like, longitudinally slotted and in its middle area bulged spring element with its two end areas each in a cross section molded recess in the contact element, while its middle, bulging area is pressing the inside of the capacitor. Because of the location Fixing its two end areas on the contact element the end regions cannot in the longitudinal direction of the contact element should emigrate, the contact pressure between the contact element and capacitor due to, for example, production-related Manufacturing tolerances become too large. Then it could have the consequence that the very thin and not very strongly adherent electrically conductive inner coating of the capacitor for example, when it is pushed onto the spring element could be damaged.
  • the invention is based on this prior art the task of an improved electrical connector specify.
  • This invention is characterized by the features of claim 1 given.
  • the invention stands out on the one hand characterized in that an elastically deformable, electrical conductive element body formed in the manner of a sleeve between the contact element and the inner surface of the capacitor is present, the element body two in Cross section has different sized end areas. Of the The cross section of the contact element is constant in this area large, so that the element body in the manner of a longitudinal direction of the contact element evading contact spring works.
  • the capacitor is also between one in the transition area between the connection side and the contact side of the Contact element formed thickening and a projection of the insulating body enveloping the capacitor in the longitudinal direction held within the connector housing.
  • the between the grounding plate and the end faces of the capacitors arranged, perforated insulating plate or insulating foil prevented the risk of a short circuit in a simple and effective manner.
  • the insulating plate ensures that the with the External surface of the capacitor connected grounding plate in none electrical contact with the thickening and thus ultimately can occur with the contact element.
  • a solder connection is between the contact element and the capacitor formed as a sleeve is not required. Thereby the assembly time is reduced.
  • the production committee compared to conventional connectors significantly reduced. The handling of the Connector occurring axial and radial movements its contact elements can be moved lengthways and crossways movable (resiliently deformable) contacts be collected without the filter elements would be exposed to a destructive mechanical load.
  • the electrically conductive element body can be rolled by a with slit-like perforations in one edge area provided band.
  • the band ends need not being closed into a ring.
