Definitions

  • the invention relates to a method for encapsulating a part of a connector which is arranged on an outer conductor having an electrical conductor of a line, with a plastic material, wherein in a region of the connector, which is encapsulated, a surface treatment is performed, according to the features of the preamble of claim 1.
  • this invention is concerned with sealing the junction of an electrical conductor connected to a connector.
  • it relates to the connection of the welding point of an electric wire, which is welded on a ring lug-like part (shunt).
  • the seal is to include the ring cable lug-like part before the beginning of the weld and subsequently extend over this weld to the isolation of the outgoing line and thus protect the weld against external loads (especially train or pressure relief) and seal (especially longitudinal water tightness).
  • the invention is therefore based on the object to improve such a generic method and to eliminate the disadvantages described above.
  • the surface treatment is carried out with a laser.
  • a surface treatment of the connector areas of the surface can be converted forming, in particular roughened, in which the plastic material can penetrate during the subsequent encapsulation to the required tightness, in particular longitudinal water tightness, to achieve.
  • the surface treatment by means of a laser preserves the mechanical structure of the connector, in particular of the area where the electrical conductor is connected to the connector so that it can not be damaged, as they occur in mechanically introduced imprints there.
  • the surface treatment is performed transversely to the longitudinal extent of the connector and around this.
  • the solution according to the invention resides in a laser-structured surface, which is applied to the plug connector, in particular the ring cable lug-like part, in a certain area and transversely around it and can then be overmoulded.
  • the surface treatment is carried out starting from an area of the connector up to the electrical conductor, in particular its outer jacket.
  • the connector is treated by laser in its surface, but also a part of the outer shell, in particular its end portion, starting from the area where the (exposed) electrical conductor is connected to the connector.
  • Such a surface treatment is readily possible because both metallic materials (connectors) and materials made of plastic (outer sheath) can be processed by means of the laser.
  • the encapsulation material used or intended in particular a thermoplastic or also a thermosetting plastic
  • This compound will meet the tightness requirements between the overmold and the metallic surface.
  • the tightness on the second mitentscheidenden side, namely the connected line material is ensured either by a conventional encapsulation process or also by, for example, a previously applied structured laser treatment of the insulating surface of the outgoing line.
  • the surface treatment takes place in the region in which the electrical conductor is connected to the plug connector, in particular welded, and / or the surface treatment takes place next to the region in which the electrical conductor is connected to the plug connector, in particular is welded.
  • a laser By means of a laser, only the area in which the plug connector is connected to the electrical conductor (for example, soldered, welded, crimped or the like) is treated in its surface.
  • a further area of the connector can be treated next to this connection area by means of a laser in its surface.
  • the outer jacket of the electrical conductor preferably in its end region, is treated by means of the laser in its surface.
  • the end region of the outer sheath, the connection area between the electrical conductor and the plug connector and possibly an area of the connector extending beyond this (in the direction of the contact region for a mating connector) are therefore very preferably treated by laser in its surface and the area thus changed in its surface structure overmoulded with the plastic material.
  • the invention thus provides, in particular, a laser-structured surface which is applied to a ring-lug-like part in a specific area and transversely encircled thereon, and the encapsulation material (in particular thermoplastic or else thermosetting plastic) used or provided in the encapsulation connects with the purpose-made structure of the lasered surface in a certain type and quality.
  • the encapsulation material in particular thermoplastic or else thermosetting plastic
