  • the space requirement for the contact arrangement is large due to the radial projection of the funnel-like extended contact socket. Especially with a desired miniaturization, such a large-sized contact arrangement proves to be disadvantageous.
  • the object is achieved with an electrical contact element of the type mentioned above in that the cover surface spans over the base surface in a spherically curved manner, while a surface area connecting the base surface and the cover surface merges continuously from the polygonal base surface into the spherical cover surface.
  • a polygonal base can be, for example, three, four, five, six or more polygonal.
  • the polygonal base should be flat.
  • the major axis should extend substantially perpendicular to the base.
  • a straight envelope contour of the electrical contact element with substantially perpendicular to each other axes is possible.
  • provision can be made, in particular, for the corners of the base area to be broken, in particular rounded in the manner of a circular arc, so that projecting pointed edges are avoided.
  • the top surface with the spherical curvature should also be arranged symmetrically to the main axis and span the base as evenly as possible and evenly.
  • the spherical curvature should be curved convexly around the mouth opening of the contact socket so that the continuous continuous transition possible from the spherical curvature of the cover surface into the surface surrounding the base surface takes place as continuously as possible.
  • an envelope contour can be formed, which is as free as possible of projections and edges. It can be provided that at least one contacting element is arranged in the contact socket of the electrical contact element.
  • the contacting element may for example be elastically deformable.
  • Such contacting elements may be, for example, contact fingers, annular contact springs, contact blades, etc.

  • the mouth opening is advantageously surrounded by an annularly rounded structure.
  • the ellipsoid is shaped in the manner of a spherical cap, which merges into the lateral surface.
  • the mouth opening can be located as a circular opening in the ball cap.
  • An eslipsoidal shape deviating from an ideal sphere also allows sufficient dielectric shielding of the orifice.
  • a ball cap also has the advantage that in the region of the spherical top surface upon rotation of the contact element about the main axis does not change its dielectric effect on adjacent components.
  • the polygonal base surface is removed from the dielectrically shielded region of the mouth opening, so that there advantageous embodiment in the form of a truncated pyramid is. Due to the pyramidal oblique portions of the lateral surface in the region of the base surface of the contact element, a transition into the spherically curved top surface is made possible in a simplified form, since the truncated pyramidal basic shape tapers in the direction of the mouth opening. A continuous transition from the truncated pyramidal basic shape in the spherical top surface is continuously free of sudden surface changes.

  • These additional body edges, which lie on the mid-perpendicular are parallel to the main axis and in each case have the same radial distance from the main axis, so that the mid-perpendiculars and the additional body edges aligned therewith lie in a lateral surface of a circular cylinder.
  • the additional body edges extend within the lateral surface of the prism.
  • portions of a circular cylindrical lateral surface for example a narrow ring or the like, can be used to produce a continuous transition from the base surface to the top surface.
  • Another embodiment may provide that body edges are broken rounded.
  • body edges in the lateral surface protruding formations In a polygonal configuration of a base surface form body edges in the lateral surface protruding formations. These body edges should be advantageously rounded rounded. On the one hand, this reduces the risk of injury to the contact elements, and on the other hand, the dielectric strength of the contact element is positively influenced since partial discharges preferably form on protruding edges. Starting from the base, the body edges, which run in the direction of the top surface, should be increasingly rounded / blunt in the direction of the top surface, so that there is a continuous transition from an angular base to a top surface with ellypsoidal cross-section.
  • the body edges By rounding the body edges, it is also possible to create a smooth transition from the polygonal base over a truncated pyramid base or a prismatic base in the ellypsoid deck surface.

This makes it possible to give off current heat from the interior of the contact piece, in particular from the contact socket out over the enlarged surface of the contact element.
  • the concave curvature is more suitable to form a simplified rounded transition to body edges and these rounded to break. This results in bulbous structures, which continue to allow a close fitting of several contact elements in the area of the base and allow for a high current carrying capacity sufficient flow around a cooling medium.
  • the extending between the corners of the base pages also have a convex curved course.
