  • DE 929 909 C discloses a socket with a socket base, two connection terminals and two resilient sockets.
  • the sockets are arranged on the socket base and are connected to the connection terminals.
  • a plug pin of a plug can be inserted into each socket along a longitudinal axis of the socket.
  • Each plug socket includes two contact legs that are symmetrical to one another, each with a contact surface for contact with the respective plug pin.
  • the contact surfaces are concave with respect to the longitudinal axis and curved along a quarter circle with a predetermined diameter.
  • the object of the invention is to increase the current carrying capacity of a socket.
  • the connector, the electrical cable, the first contact pin and the first correspondence connector do not belong to the contact unit.
  • the contact unit proposed according to this aspect enables a higher current carrying capacity compared to that of DE 929 909 C well-known resilient socket.

  • each contact socket can, for example, contain no additional or at least one additional contact leg, which is designed to rest on the first contact pin and is electrically conductively connected to the at least one connection contact.
  • each contact leg can be connected to at least one of the connection contacts, for example directly in an electrically conductive manner, in particular by being formed in one piece with at least one of the connection contacts, or indirectly, in particular via a cable, a wire, a busbar or an electrical component for example includes a switch and/or an electrical fuse.
  • the contact socket can or rests against the inserted contact pin with at least four areas, namely at least with the first contact area, the second contact area and the third contact area of the first contact leg as well as with the at least one area of the second contact leg.
