Definitions

  • the invention relates to an electrical Connector assembly with a flat cable and one Strain relief and a method for producing a Combination of connector and flat cable.
  • Multipole connectors are often used assigned cables with a corresponding number of conductors connected.
  • the strands are often the case with recent automotive developments executed that individual conductors are arranged side by side and form a multi-core cable, the individual conductors of which the respective contacts of the connector partly individually must be connected.
  • this takes away the risk from swapping the individual conductors of a cable to what leads to electrical misallocation and usually corresponding malfunctions.
  • Flexible film conductors are becoming increasingly alternative used, which typically consists of a base film, a Number of flat, essentially in cross section rectangular metallic conductors and a cover film consist. The conductors are juxtaposed and are between the two slides. The leaders are typically about 0.5 mm to 4 mm wide and about 0.05 mm thick.
  • a connector is known from DE 197 47 116 A1, at which only the contacts of the connector with the electrical conductors of a flat cable Ultrasonic welding are electrically connected.
  • This electrical connection has only a very small mechanical tensile strength due to the electrical conductors themselves are typically very thin. Therefore, in this conventional procedure for strain relief electrical connection holes punched into the cable into the a corresponding pin, which is located on the connector, intervenes. But this type of strain relief often leads to the unwanted initial violation and also a Widening of the foil conductor because of the space for the Punch holes.
  • the connector housing must be made accordingly be made wider around the snap-in pins to attach what an increased material requirement and thus a increased weight.
  • the connector housing is integrally attached to the Molded film conductor. This method is with one complicated manufacturing process. Since also with one-piece molding of the housing onto the smooth surface no integral connection with the foil conductor can be reached, strain relief pins are also on Connector housing attached in the foil conductor engage, increase the risk of injury to the foil conductor and cause additional material and space requirements.
  • the invention is therefore based on the object inexpensive, reliable and permanently tensile electrical connector assembly with a flat cable, especially available with a flexible foil conductor do.
  • the invention provides an electrical connector assembly available a flat cable with one or more electrical conductors, some of which are dielectric Isolation material are surrounded and a connector with a or more electrical contacts and a dielectric Housing includes.
  • the contacts are with the heads of the Flat cable electrically connected and the flat cable is with the connector for strain relief essentially not detachable mechanically connected.
  • the mechanical connection contains one connection between the insulation created by welding of the flat cable and the housing of the connector. The welding surprisingly does not lead to an essential one Violation of the flat cable and still granted a permanent tensile connection. Welding is quick and inexpensive perform what a high production speed enables and saves costs. Because both the housing as well the cable insulation is preferably made of plastic create a welded connection in a simple manner. The mechanical connection is nevertheless heat-resistant.
  • the connector assembly advantageously high tensile strength, especially since the insulation of the flat cable and that Connector housing itself are designed to be stable in tension.
  • a such permanent mechanical connection is also long-term and permanently vibration-proof.
  • the Shape of the area in which is welded to the Connector geometry are adjusted, i.e. this can e.g. also be flat.
  • a flat mechanical connection leads to a distribution of the occurring forces, so that the mechanical connection is evenly loaded.
  • the connector assembly is insensitive to high Humidity, a typical requirement in the Automotive area has a shelf life of 1000 hours 85% relative humidity and a temperature of 80 ° Celsius, which is safely maintained by the invention.
  • An electrical according to the invention Connector assembly with a flexible foil conductor is e.g. resistant to windscreen washer fluid, greases and oils.
  • foil conductor use in which the electrical conductor between a dielectric base film and a dielectric cover film are arranged.
  • the mechanical connection advantageously comprises a Weld between the base and / or cover sheet with the Casing.
  • the base and cover films can be made from Polyester. Polyester is easy to weld and is particularly stable and long-term resistant.
  • the welding is preferably by means of laser welding executed.
  • Laser welding is especially with Infrared lasers can be executed quickly, precisely and cleanly. The In particular, laser welding can still be carried out if the contacts and the flat cable are already in their Target position are arranged in the connector housing.
  • the Laser welding is particularly suitable for flexible ones Foil conductors, since the base and cover foils are typically have a relatively high transmission for the laser light.
  • the laser beam is preferably applied to one for welding Area directed between the conductor tracks of the film conductor and thereby essentially heats the dielectric housing through the base and cover film.

  • the electrical connection is at such a flat cable prepared in the area of stripped conductor manufactured.
  • the Contacts and the conductors connected by crimping or the contacts encompass an area from which the Flat cable is penetrated. Even from one insulation penetrating electrical connection goes in advantageously no cracking of the flat cable, because the mechanical connection provides effective strain relief, especially the penetrated areas.
