Definitions

  • the invention relates to a charging cable-side plug part of an electrical plug-in device of a vehicle, in particular a passenger car, for connection of an electrical charging cable to a provided on the vehicle socket part, with at least one arranged in the plug housing high-current contact, the plugged in in the socket part between a retracted first position in which it is electrically separated from a provided in the socket part, pin-shaped mating contact, and a second advanced position in which it is electrically connected to the mating contact, displaceably arranged.
  • batteries are required, which can be charged with very high currents of currently up to 200 A at a voltage of up to 500 V, but also electrical plug-in devices that allow the secure transmission of such electrical power.
  • the charging cable side connector parts must therefore meet high technical requirements. Because in addition to being attachable to the vehicle side ge socket part, which must be done similarly simple as the insertion of the nozzle in the tank opening of an internal combustion engine-powered vehicle, electrical power in the above-mentioned level must be transmitted as DC, since rectifiers that come into consideration for such services, consuming and bulky are so that installation of such in a vehicle is not desirable.
  • the invention is therefore based on the object to provide a charging cable-side plug part of an electrical connector of a vehicle, which is suitable for fulfilling the requirements explained above.
  • this object is achieved by the reproduced in claim 1 charging cable side connector part.
  • this connector part includes at least one, preferably include all high-current contacts, which are usually the connection of the DC charging current, connected to a wire of the charging cable pin contact part and a sleeve contact part.
  • the sleeve contact part is electrically connected to the pin contact part. It has a free end region adapted to the mating contact, so that the end region can be pushed onto the mating contact provided on the vehicle while making electrical contact.
  • the sleeve contact portion comprises a sliding portion configured such that the sleeve contact portion is electrically disengaged from the first position in which it is electrically separated from the mating contact provided in the female portion, leaving its electrical connection with the pin contact portion, and the second position it is electrically connected to the mating contact, is arranged to be displaceable, the mechanical connection between the charging cable-side plug part and the vehicle-side socket part can be completely accomplished before the electrical connection is made.
  • the latter is subsequently produced by merely displacing the sleeve contact part, which is moved from the first to the second position manually by suitable measures from the outside or else by motor means with the aid of a device integrated in the plug part.
  • a significant advantage of the plug part according to the invention is that the pin contact part, with which a wire of the charging cable is connected, is not displaced relative to the plug housing.
  • the charging cable and the pin contact part can thereby be firmly connected to the plug housing, for example by encapsulation of cable and pin contact part ends with the insulating plastic material of the plug housing, so that a stable, durable and thus operationally safe solution is achieved.
  • the displacement region of the sleeve contact part has an approximately circular inner cross section and the pin contact part has an approximately circular outer cross section.
  • the radii of the inner and outer cross sections are preferably dimensioned such that an annular gap remains between them, in which at least one contact element effecting the electrical connection between the sleeve contact part and the pin contact part is arranged.
  • This contact element may, for example, be one which, with sufficient electrical conductivity, reduces the sliding friction between the sleeve contact part and the pin contact part.
  • the contact element comprises a ring-shaped coil spring made of a material having sufficient electrical conductivity.
  • These contact elements also referred to below as “ring spiral springs”, can be configured in such a way that the ring inner diameter is slightly smaller than the outer diameter of the pin contact part in the state not yet pushed onto the pin contact part, so that the ring spiral spring is in the pushed state under a elastic force on the pin contact part is present. An effective electrical contact is thereby ensured.
  • the ring spiral spring has a spiral diameter, so that the outer diameter of the ring in the pushed onto the plug contact part state is slightly larger than the inner diameter of the sliding portion of the sleeve contact part.
  • the coil spring When moving the sleeve contact part on the pin contact part, the coil spring in the event that it is not fixed, for example, by a bearing in a groove either opposite the pin contact part, or with respect to the sliding portion of the sleeve contact part, perform a rolling movement, whereby the neces sary for the sliding movement Reduced force and abrasion-related wear is reduced.
  • the free end region which can be brought into electrical connection with mechanically attached to the vehicle-mounted socket part connector part with the mating contacts provided in the socket part, is preferably tulpentitleförmig formed with slots separated from each other by contact tabs.
  • the mating contact provided in the socket part can be designed to be particularly simple and therefore cost-effective as a simple pin contact, preferably with a conical free end which facilitates the sliding of the tulip-contact-shaped end region.
  • the contact tabs can be shaped in such a way and consist of a material such that their inner sides essentially interact with the latter in a state pushed onto a mating contact.
  • the contact tabs may be surrounded by a spring element outside, which increases the pressure on the mating contact.
  • the pin contact part can in principle be connected in any way with the associated wire of the charging cable. However, it is particularly preferred to provide a crimp connection for this purpose, since this equally ensures a reliable mechanical and electrical connection and is insensitive to changing mechanical loads and high temperatures.
  • the plug part can comprise further electrical contacts for producing an AC and / or signal transmission between the vehicle and a charging station.
  • electrically powered vehicles which additionally have an in-vehicle rectifier arrangement, which converts the usual mains AC voltage of, for example, 220 V with a maximum current of 16 A in a charging current suitable for charging the battery of the vehicle.

This can serve, for example, to notify the charging station of a proper mechanical connection before the sleeve contacts are released for displacement from the first to the second position or moved by a motor.
