Definitions

  • the invention relates to a connector specified in the preamble of claim 1 genus.
  • a connector which comprises a plug part and a female part, which are sealed to each other via an interposed O-ring.
  • O-ring For the O-ring, a sufficient sealing effect must be ensured. Inadequate tightening of the connector may result in leaks. To ensure sufficient tightening, it is known to tighten connectors with a torque wrench.
  • the invention has for its object to provide a connector of the generic type, in which a simple way a good seal is ensured.
  • the profile seal has at least one radial sealing surface.
  • the radial sealing surface is already working when the connector is not fully tightened. This ensures a good seal.
  • the profile seal can also compensate for occurring tolerances comparatively well.
  • the profile seal additionally or alternatively on at least one axial sealing surface. An additional axial sealing surface, the sealing effect can be ensured even if the radial sealing surface is damaged, for example.
  • a simple production results when the profile seal is molded onto one of the contact carrier. Accordingly, the profile seal does not have to be mounted as a separate component and can not be lost during operation due to the fixed connection with the contact carrier. This results in a simple structure with few individual parts.
  • the profile seal is held in particular on the socket part and is located on the housing of the plug part.
  • the locking means and counter-locking means form an axial latching, which acts in the direction of the longitudinal center axis of the connector.
  • the latching means and counter-latching means form a radial latching, which acts in the radial direction of the connector.
  • the axial latching comprises at least one axial catch, which cooperates with latching depressions.
  • the number of axial detents is in particular smaller than the number of detent recesses.
  • For the radial locking at least two latching arms are advantageously provided, wherein advantageously in each position of the latching means and counter-latching means at least one latching arm is arranged in a region without radial notches. It is advantageous in each position of the locking means and counter-locking means at least one locking arm in engagement.
  • the nut can still dodge in the axial direction, so that the locking recesses lead to a significant haptic feedback, but not to excessive complicating the tightening of the connector.
  • the radial locking engages in addition to the axial locking.
  • a simple design results when the non-rotatably provided with the nut locking means are formed on a locking ring which is rotatably connected to the nut.
  • the cap nut has in particular a bent edge which holds the locking ring.
  • a simple construction is achieved if at least one latching arm is formed on the latching ring.
  • the in Fig. 1 Connector 1 shown comprises a plug part 2 and a socket part 3.
  • the plug part 2 comprises a contact carrier 5, on which a sleeve part 11 is mounted, which surrounds the contact carrier 5.
  • the contact carrier 5 has on its side facing the socket part 3 a thickened end portion 42 which on its side facing away from the socket part 3 forms a stop 14 for the sleeve part 11 against which the sleeve part 14 abuts.
  • the sleeve member 14 has on the side facing the socket part 3 on its outer side an external thread 12.
  • the sleeve member 11 also has a Operating portion 45 on the side facing away from the socket part 3, on which the sleeve part 11 can be held.
  • the sleeve part 11 can be rotatably mounted on the contact carrier 5.
  • the plug part 2 has a conventional structure.
  • the contact carrier 5 has a plurality of receptacles 7 for receiving contact pins.
  • the contact pins not shown, project into a receptacle 21 of the contact carrier 5.
  • the female part 3 comprises a contact carrier 6, which has a plurality of receptacles 8 for contact sockets, not shown, in the contact pins in the in Fig. 2 shown assembled state of the connector 1 protrude.
  • the contact carrier 6 has a radially outwardly projecting edge 13, on which a profile seal 15 is held.
  • the profile seal 15 is molded onto the contact carrier 15 in two-component injection molding.
  • the contact carrier 6 advantageously consists of a largely dimensionally stable plastic and the profile seal 15 made of an elastic plastic such as silicone or rubber material.
  • the profile seal 15 is formed as a separate component and is fixed to the contact carrier 6, for example by tying the profile seal 15 in a receiving groove of the contact carrier. 6
  • a union nut 9 is arranged rotatable about a longitudinal center axis 4.
  • the union nut 9 is rotatably connected to a locking ring 16 which rests against the profile of the seal 15 facing away from the edge 13.
  • the union nut 9 has an internal thread 10 which is screwed into the external thread 12 of the sleeve part 11 and thus secures the socket part 3 in the direction of the longitudinal central axis 4 on the plug part 2.
  • the union nut 9 engages over the locking ring 16, the edge 13 of the contact carrier 6 and the profile seal 15th
  • the profile seal 15 has an axial sealing surface 20 which bears against an end face 44 of the end portion 42 of the contact carrier 5.
  • the profile seal 15 has a sealing lip 22, which projects to the plug part 2 and on the inner circumference of a radial sealing surface 19 is formed.
  • the sealing surface 19 abuts a circumferential surface 43 of the end portion 42 of the contact carrier 5.
  • the profile seal 15 thereby acts in the axial and radial direction relative to the contact carrier 5 and seals the receptacle 21 from the environment.
  • the sealing surfaces 19, 20 of the profile seal 15 rest exclusively on the contact carrier 5. It is advantageous no contact of the profile seal 15 given to the rotatably mounted sleeve portion 11, so that no rotational relative movement takes place on the profile seal 15.
  • the profile seal 15 seals with the radial sealing surface 19 already when the plug part 2 and the female part 3 are not yet firmly connected, the internal thread 10 of the union nut 9 is thus only partially screwed into the external thread 12 of the sleeve part 11. As a result, no defined screw-in depth or defined tightening force of the screw connection is necessary for achieving the required sealing effect.

  • the also in Fig. 3 shown outside 26 of the profile seal 15 is slightly conical.
  • the outer diameter a decreases from the side facing away from the edge 13 to the edge 13 facing side to a diameter a ', which is advantageously smaller by about 0.5% to about 3% of the thread diameter than the diameter a.
  • the profile seal 15 has an inner diameter c, which is advantageously about 80% to about 88% of the nominal diameter of the thread.
