Definitions

  • the invention relates to an electrical contact element for a plug connector, a plug connector and a method for producing an electrical contact element.
  • Electrical contact elements are used in electrical connectors to establish electrical contact between an electrical wire or cable and a mating connector.
  • the contact elements are designed to be rigid, at least in some areas, in order to withstand mechanical stress during the plugging of the connector into the complementary connector.
  • the quality of the electrical connection between the contact element and corresponding complementary contact elements of the complementary connector is of decisive importance, particularly when transmitting high-frequency electrical signals via such connectors.
  • the electrical contact resistance between the two should be as low as possible and as constant as possible as a function of the frequency.
  • the surface of the contact element which is designed to come into contact with the complementary contact element is usually machined, for example turned to a cylindrical shape.
  • the mechanical processing of the contact element leads to a complex production process.
  • the pamphlet EP 1 231 675 A2 discloses an electrical contact element and a method for its manufacture, in which a preform is stamped out and its contact area is folded along its longitudinal axis.
  • the goal here is to obtain an approximately square cross-section with side surfaces that are as planar as possible.
  • the pamphlet WO 2007/009487 A1 relates to another electrical contact element whose contact area is folded along its longitudinal axis into a square cross-section.
  • the contact area of the contact element is then rotated by 90 degrees in relation to the rest of the contact element, so that the electrical contact on one side of the contact area without Nut comes about.
  • the pamphlet U.S. 4,434,552 discusses a method of manufacturing a cylindrical contact element in which an outer shell of the contact element is stamped and rolled by cold forming and an inner part placed in the outer shell from sheet metal.
  • the pamphlet EP 1 403 975 A2 describes a contact element with a hollow mounting portion having lateral and horizontal windows for inserting a cable.
  • the pamphlet U.S. 4,969,839 shows a socket having insulation displacement contacts for attaching cables to the female contact elements of the socket.
  • the pamphlet DE 202 08 436 U1 discloses a one-piece contact element made of stamped and rolled sheet metal material with a mating end and a connecting end, the mating end being designed as a pin and having a square cross-section. Furthermore, the edges of the pen are rounded.
  • the contact element can be produced easily and quickly, with the plug-in contact area having increased mechanical strength due to the essentially prismatic shape.
  • the electrical contact element is made of an electrically conductive material, in particular a metal, in which case an electrical current can flow from the plug contact area to the line contact area.
  • the line contact area of the contact element is connected to an associated electrical line electrically contactable or electrically connectable.
  • the electrical line can be attached to the line contact area in a detachable or non-detachable manner.
  • the plug-in contact area with a associated complementary contact element of the complementary connector electrically or mechanically contactable. An electric current can therefore flow from the electric line via the contact element to the complementary contact element.
  • forming describes manufacturing processes in which the material of the contact element, in particular a metal, is plastically brought into a different shape.
  • an originally shaped, for example a cast, rolled or punched starting material, ie the preform is formed into the final contact element.
  • the material retains its mass and cohesion during forming.
  • forming within the meaning of the invention differs from a general deformation of the material in that the change in shape is brought about in a targeted manner, while deformation represents an untargeted elastic or plastic change in shape, for example when Bending during insertion of the contact element.
  • neither material is added nor removed from the contact element during the forming process.
