Definitions

  • the invention relates to a high-current connector for contacting electrical or electronic assemblies, in particular in the automotive field. Due to the increasing electrification in the automotive sector, more and more powerful starters, alternators, etc. are used. Especially for the energization of electric motors, which are arranged in the drive train of the motor vehicle as a combined starter, alternator and vibration damper, very powerful high-current connectors are required both on the electric motor and on its control unit, which can at least briefly transmit currents of about 3000 amperes.
  • the spring contacts are relatively long and bulbous, so that a large contact area between the plug contact and the sleeve is ensured at high contact pressure.
  • electromagnetic radiation is difficult to contain.
  • Another variant of conventional high-current contacting is to provide a connecting bolt with an external thread.
  • One is attached to a cable via the connecting bolt pressed or welded contact clamp pushed with an eyelet and screwed using a nut. Any braided shield of the cable is connected to the housing ground.
  • This configuration also has a number of considerable disadvantages. On the one hand, they have very large dimensions for the required current carrying capacities. Furthermore, separate nuts are required, which are also to be secured for vibration-proof contact. Assembly errors are possible because the thread can be deformed if the nut is incorrectly fitted, or the connection bolt as a whole can be torn from its storage. In addition, the assembly takes a relatively long time.
  • a current connector is known in which spring-like contact elements are arranged in two on opposite surfaces of a cylindrical contact pole.
  • An essentially U-shaped contact pole shoe engages around the contact pole in such a way that the spring-like contact elements establish an electrical connection between the contact pole and the contact pole shoe, since the spring-like contact elements protrude from the corresponding grooves in the contact pole, thereby compressing them when they are joined together with the contact pole shoe and ensure a firm contact between the contact pole and the contact pole shoe.
  • the electrical contact arrangement known from DE-GM 66 08 865 essentially has a structure which is comparable to the structure of the current connector according to GB 1 542 102, contact rods being used here instead of the spiral spring-like contact elements of GB 1 542 102 which are to be adjusted or deflected between the contacts with a contact pole and a contact pole shoe in such a way that it is primarily subjected to torsion when the contact is made.
  • contact strips are described in which a plurality of contact bridges are arranged between edge strip carriers serving as contact surfaces.
  • contact elements for electrically connecting a contact pole and a contact pole shoe of high-current connectors which are designed as contact spring elements or spring-like contact strips, are shown in

  • very safe installation is possible in the smallest space.
  • good accessibility of individual contact poles is ensured with multi-pole arrangements.
  • the cylindrical contact pole has an essentially polygonal, preferably quadrangular base surface, the contact spring elements being provided on two opposite surface sections.
  • the contact pole piece has an essentially U-shaped shape and overlaps the contact pole in the connect / disconnect direction with two legs.
  • the contact pole shoe can clamp the contact pole firmly, the contact spring elements effecting a safe and resilient contact.
  • the contact pole shoe preferably has lateral contacting on one of the legs for a connecting line.
  • the contact spring element has two spaced apart carrying straps, between which a plurality of lamellar contact webs are arranged in order to establish an electrical connection between the contact pole shoe and the respective surface section of the contact pole.
  • This configuration represents a particularly high current carrying capacity with high vibration resistance.
  • the carrying tapes are preferably made of spring steel and the contact webs are made of copper or a copper alloy, the contact webs being shaped and arranged between the carrying tapes in such a way that electrical current from at least one contact point on a side of the contact web facing the contact pole piece flows to at least one contact point on a side of the contact web facing the contact pole.
  • the contact points can be flat or linear.
  • the contact webs preferably have an elongated shape and are curved with their two end regions in the direction of the contact pole or the contact pole shoe.
