Definitions

  • the invention relates to a circular connector, in particular a push-pull connector, for detachable connection to a mating connector, and a connector system.
  • Circular connectors are known for connecting a data, signal or power cable and for establishing an electrical connection with a complementary mating connector.
  • meeting tightness requirements can also be important. For example, it may be required that penetration of a fluid, in particular liquid, and/or dust into the plug connector must be prevented.
  • a connector has sealing elements at suitable locations that are intended to prevent fluid and/or dust from penetrating.
  • sealing elements can be provided which are intended to provide a tight connection between the circular connector and mating connector.
  • the provision of appropriate sealing elements between the circular connector and the mating connector often increases the effort required to connect the circular connector to the mating connector, since the sealing element is exposed to the relative movement between the circular connector and the mating connector required for connection.
  • the sealing element can be damaged when connecting and disconnecting the circular connector and the mating connector.
  • the provision of the first sealing section and the lip section enables the sealing element to be easily adapted to the space or distance between the insertion area and the insertion area.
  • the connection of the circular connector to the mating connector or the insertion of the insertion area into the insertion area can be carried out without great effort and yet a reliable, tight connection can be provided between the insertion area and the insertion area.
  • the plugged-in state is understood to mean a state in which the circular connector is electrically and mechanically connected to a complementary mating connector.
  • the circular connector can be a male or a female circular connector.

  • the insertion area has a cylindrical section against which the first sealing section rests, and/or the insertion area has a cylindrical recess against which the lip section acts in the inserted state.

Accordingly, the distance between the lip section and the sealing section increases as it runs counter to the insertion direction.
  • the sealing element can have a circumferential wedge-shaped recess, the pointed end of which points in the direction of the insertion direction, the wedge-shaped recess separating the lip section from the first sealing section.
  • the angle of the pointed end of the wedge-shaped recess determines the previously specified angle of attack.

  • the ring 216 is part of an actuating element 218 which is movable along the insertion direction E and relative to the locking means 214 on the connector side.
  • a sufficiently strong pull on the ring 216 against the insertion direction E causes a relative movement between the circular connector 200 and mating connector 300 and thus also between the locking means 310 on the mating connector side and the locking means 214 on the connector side.
