Definitions

  • the invention relates to an electrical contact arrangement having a first contact piece having a first contact region and a second contact piece having a second contact region, wherein the first contact piece is electrically connectable to the second contact piece by means of a coupling contact piece having a third and a fourth contact region, wherein the first and in each case the third or the fourth contact region is assigned to the second contact region, wherein the respective mutually associated contact regions each have a contact opening and a contact pin which can be inserted into the contact opening, wherein the contact pins have a convex section at their ends facing the contact openings, at least with respect to a plane
  • An electrical contact arrangement is for example from the published patent application DE 39 04 439 A1 known.
  • An electrical contact arrangement described there as a disconnect contact device connects a stationary connection conductor with a mating contact piece, which is arranged on an interrupter unit of a compressed gas circuit breaker.
  • a contact blade containing jacket piece is provided for electrical connection.
  • the shell piece connects the connection conductor and the mating contact piece rigidly together. Mechanical vibrations of the individual conductors to each other are transmitted through the shell piece.
  • a dome contact piece provided with a constriction, wherein in the constriction an insulating is inserted.
  • About the insulating the dome contact piece is held in a tubular housing. Due to the disc-shaped shape is a mobility of the dome contact piece in the axial direction possible. Radial movements or tilting, for example, can not be performed due to the piston-like shape of the insulating washer which is fitted in the cylindrical housing. Thus, it is not possible to respond to vibrations in a suitable manner.
  • An electrical contact arrangement of the aforementioned type is known from US 3,064,226 known.
  • a dome contact piece is provided, which is pressed by means of spring forces against contact areas of a first and a second contact piece. A positioning to the contact pieces is ensured by the applied spring forces.
  • stops are provided against which the dome contact piece strikes.
  • the mass of the moving parts is increased by the attachment of additional spring elements.
  • the movable parts between the stops are freely movable. Thus, an available free path can be used to accelerate the moving mass. An acceleration of the moving mass is disadvantageous because a force effect is increased and a swing is supported.
  • the present invention has for its object, an electrical contact arrangement of the type mentioned in such a way that the arrangement is less sensitive to mechanical vibrations.
  • the object is achieved in an electrical contact arrangement of the type mentioned according to the invention that the dome contact piece is slidably mounted in a bearing cup.
  • the first contact piece is mechanically decoupled from the second contact piece.
  • the dome contact piece can move in response to the movements of the two contacts and allows compensation movements. If the convex portions extend only with respect to one plane, ie only be convex two-dimensionally, then small-volume electrical contact arrangements result, in which the dome contact piece can be pivoted within the plane.
  • Such arrangements may, for example, comprise contact pins punched out of a sheet metal, wherein the contact pins can be inserted into slot-shaped openings.
  • a good contact with a good decoupling lateral forces ensures an embodiment of the convex portions as rotationally symmetric sections. Lateral movements of the first contact piece relative to the second contact piece are decoupled from each other while maintaining the required electrical contact.
  • the bearing cup guides the dome contact piece and absorbs their weight forces.
  • the bearing cup may be made of various materials such as metals or plastics.
  • self-lubricating plastics which allow a smooth sliding of the dome contact piece in the bearing cup, are particularly advantageous.
  • a suitable plastic is, for example, polytetrafluoroethylene.
  • first and the second contact region are designed as contact pins and the third and fourth contact regions as contact openings.
  • the dome contact piece may be designed, for example, in the form of an elongate sleeve which, as in the case of a pipe, has contact openings at axially opposite ends.
  • the dome contact piece may be designed, for example, in the form of an elongate sleeve which, as in the case of a pipe, has contact openings at axially opposite ends.
  • first and the second contact region are formed as contact openings and the third and the fourth contact region as a contact pin.
  • the dome contact piece can be configured in a very slim manner.
  • the contact pieces can be made of recesses, combined, for example, with shielding electrodes. Such arrangements can be used for example for electrical contact arrangements in confined spaces.
  • first and the fourth contact area are formed as contact openings and the second and third contact area as contact pins.
  • Such a configuration of an electrical contact arrangement allows both the production of an electrical contact using the dome contact piece with the advantages in terms of decoupling occurring at the contact pieces lateral forces, as well as the immediate coupling of the contact pieces together.
  • For an immediate coupling of the contact pieces with each other it is necessary to match the dimensions of the contact openings and the convex portions of the dome contact piece or the contact pieces to each other.
  • a direct electrical connection of the contact pieces with one another can be provided, for example, on devices which allow no or only slight lateral movements of the contact pieces to one another.
  • the longitudinal axes of the contact pins are arranged obtusely in a projection to each other.
  • the longitudinal axes of the contact pins should be arranged almost parallel almost congruent to each other. This makes a simple coupling possible. In a projection on a plane, however, it is permissible that the longitudinal axes of the contact pins are arranged at an obtuse angle to each other.
  • the electrical contact arrangement is also suitable to compensate for production-related offsets or tilting of the contact pieces to each other.
  • a further advantageous embodiment can provide that the dome contact piece is slidably mounted in a bearing cup.
  • one of the contact pins engages through the bearing cup.
  • the bearing cup lies in one of the contact openings.
  • Arrangements of the bearing cup around a contact pin or within a contact opening allow very compact embodiments of the electrical contact arrangement.
  • the same assembly can be used to hold the bearing cup, which also carries a contact pin or a contact opening. Separate interception and support facilities for mounting the dome contact piece are not required.
  • the bearing cup allows a direction of the dome contact piece directed on all sides to a longitudinal axis of the dome contact piece.
  • the dome contact piece By supporting the mobility of the dome contact piece on all sides, the electrical contact arrangement in almost all layers effectively relieved of weight forces of the dome contact piece.
  • the dome contact piece itself can be rotatable about its longitudinal axis and also perform tumbling movements.
  • the bearing shell can be designed so that even precession movements are supported around the longitudinal axis of the dome contact piece.
  • portions of a ball cap can be provided as a bearing socket, wherein both the concave and the convex side of the ball cap can be used as a bearing socket.
  • a further advantageous embodiment can provide that at least one of the contact openings is bounded by a surface which is part of a spherical cap.
