Definitions

  • the invention relates to a crimp contact of a flexible foil conductor with at least a conductor track defined on an insulating carrier layer, wherein the area to be contacted of the conductor track defined on the film in one compressed crimp part is arranged, which in the uncompressed state at least two directly opposite one another, U-shaped from one leg protruding cheeks.
  • Foil conductor with electrical fixed on an insulating support layer Conductor tracks are known.
  • the advantages of this foil conductor are in particular in their low height and low weight.
  • a crimp contact is generally a contact Understood arrangement in which the contact between those to be contacted Divide by pressing or squeezing a deformable Part ("crimp part") is produced.
  • one made of stranded wires electrical conductor is the electrical conductor to be contacted in one in the Usually inserted U-shaped sheet metal part and the cheeks of the U-shaped sheet metal part are then compressed, causing the inserted electrical Head is clamped and also deformed.
  • This enables electrical conductors to make simple, quick and reliable connections getting produced.
  • a common quality feature of such a connection is their gas tightness, which is due to the deformation work performed the surfaces of the parts to be connected.
  • Crimp contacts for foil conductors are also known, for example from CH-PS 585 975 or US-PS 5,137,468.
  • the from CH-PS 585 975 and the US-PS 5,137,468 known crimp contacts of flexible film conductors are in the In contrast to the conventional crimp contacts of stranded conductors, it is not very reliable.
  • With the crimp contact of CH-PS 585 975 the tips of the crimping part through the conductor tracks defined on the film and then bent, pushing them again through the conductor track.
  • the contact areas are essentially only through the penetration points the tips are formed by the conductor track.
  • An electrical connector for connecting a foil to a wire conductor is further known from DE-OS 1 957 183.
  • the connector has two through one Fold line separate flank parts.
  • a tongue is from one side of the flank punched out and bent up in a U-shape.
  • the wire conductor is in this U-shaped tongue inserted.
  • the foil conductor is between the tongue and the other flank part inserted and subsequently the connector for making the contact pressed together.
  • the wire conductor and the foil conductor lie here compressed Condition of the connector not against each other and a gas-tight Such a connector cannot form contact with the film conductor become.
  • From US-PS 3,715,457 is also a two-part connector for a ribbon cable known.
  • the conductors are relatively loose between two Layers made of an insulating material.
  • the connector has a lance-like Part on that from the front end of the ribbon cable between the top insulating top layer and the conductor is inserted so that it is lance-like Part lies flat on the conductor.
  • the cheeks of a U-shaped Crimp parts are from the back of the ribbon cable through the insulating Lay through next to the conductor, so that the conductor and the lance-like Part of the connector as well as the insulating layers between these cheeks come to rest. As a result, the cheeks are pressed inwards, with their tips piercing the upper insulating layer and on the lance-like Part are pressed. This does not create a gas-tight connection reached.
  • the object of the invention is to provide a crimp contact of a flexible foil conductor, that is easy to manufacture and reliable, that in its manufacture allows sufficient tolerances and is gastight.
  • Successful according to the invention this in that the foil conductor in the area of the conductor track to be contacted is electrically conductive on its surface facing away from the carrier layer and that in the compressed crimp part also a deformable and when pressed together of the crimped deformed pressure part is arranged on the foil conductor abuts, the crimp contact being gas-tight.
  • the crimp contact is thus made by next to the contact or contacts A deformable pressure part is also inserted into the crimp part and then the crimp part is pressed. Through the deformation work done a safe, gas-tight seal is created on the surfaces of the parts to be connected Contact of the film with considerable manufacturing tolerances positioning of the foil in the crimp part. Due to the gas tightness of the Crimp contacts do not get liquids or harmful gases (such as sulfur gases) in contact, which would otherwise lead to corrosion and thus to impairment of contact.
  • EP 1 035 616 A1 which is also a crimp contact of a flexible Foil conductor shows.
  • the protruding from a connecting web or leg Cheeks of the crimping part are not directly opposite each other here, however are arranged offset to each other (seen in the longitudinal direction of the film conductor). This means that the crimp contact is not gas-tight.
  • the electrical contacting mediated by the crimp contact according to the invention of the foil conductor can affect different parts: On the one hand, an electrical Contact between the conductor track and the deformable pressure part made which in this case is a section of an electrical conductor, preferably a stranded wire or waveguide.
  • the crimping part can be a be an independent part of the parts to be contacted, which is also electrical can be insulating.
  • the electrical contact between the Conductor and the crimp part may be formed, in which case the deformable Pressure part can be a part independent of the parts to be contacted and can consist of an electrically insulating material.
  • Another alternative is that a contact between two arranged in the crimp part, with Your conductor tracks are directed against each other foil conductors.
  • both the crimp part and the Pressure part independent of the electrical contact and also from one electrically insulating material exist.
  • Multiple pairs of can also be used contacting foil conductors in the crimp part.
  • the mentioned contact options can also be combined with each other. For example could the conductor track of a foil conductor with the free end of a Stranded wire formed deformable pressure part and with a crimp part be contacted, which on a connector pin of a connector part of an electrical Plug connection is formed.
  • FIG. 1 and 2 of a crimp contact are two conductor tracks 3 which a film conductor 1 (only a part of this is shown in Fig. 1) are contacted with electrical conductors in the form of stranded wires 13.

  • the contact area can be crimped by dipping, overmolding or other processes are sealed.
  • the base plate 6 and the bracket 14 serve for prepositioning the parts of the crimp contact (conductor track 3 of the foil conductor, Crimp part 7, pressure part 12).
