  • the electrical arrangement according to the invention with the features of claim 1 has the advantage over that a frictional surface is significantly reduced during a Aufsteckens or removal of the direct plug over the prior art and also only a linear friction occurs during the sliding movement.
  • significant signs of wear on direct contacts of the direct plug-in element and contact areas of a carrier plate can be reduced.
  • the direct plug-in element can easily be disconnected from the carrier plate several times and put on again.
  • thinner protective layers which are usually made of gold, can be used on the contact surfaces at the contact areas or the direct contacts. This allows a significant cost savings.
  • the electrical arrangement comprises a carrier plate, e.g. a printed circuit board, having at least first and second contact regions, which are arranged exposed on the carrier plate and are spaced at different distances from a support plate edge.
  • a direct plug-in element is provided with a housing and at least first and second direct contacts, each having at least first and second point contacts, wherein in the mounted state, the first point contact the first contact area and the second point contact contacts the second contact area.

  • the direct contacts contact the carrier plate at different angles, ie the direct contacts are arranged at different angles to a carrier plate plane.
  • the positions of the point contacts correspond to the angular orientation of the direct contacts relative to the carrier plate.
  • the point contacts z. B. manufacturing technology in a simple manner from the arcuate portion of the direct contacts are pronounced.
  • the direct contact comprises a spring element, which exerts a bias on the point contact in contact.
  • the spring element is arranged on a side opposite to the point contacts side of the direct contact and integrally formed of a material of the direct contact.
  • all direct contacts are identical. This allows a particularly simple construction of the direct plug-in element, whereby considerable cost savings can be achieved by a plurality of identical parts. More preferably, the first and second contact region are arranged on a same flat side of the carrier plate.
  • the invention further relates to a direct plug-in element having a housing and at least one first and second direct contact, each having at least one first and second point contact, which are arranged above, preferably on an arcuate portion of the direct contact. More preferably, the direct plug-in element has a spring element formed in particular in one piece with the direct contact in order to provide a spring force on the point of contact between the point contact and the contact area.
