  • the present invention relates to a housing assembly for a plug connector comprising a coupling device, for example, but not exclusively, for an electrical plug connector for use in the automotive sector. Furthermore, the present invention relates to a plug connector and a connection assembly with such a housing assembly.

Once the retaining projection has been introduced into the retaining groove, the retaining projection may no longer be moved, in particular, in the radial direction. As a result, a motion of the coupling device away from the final plugged position is prevented.

Furthermore, connector housing 18 comprises a coupling device 26 which is configured to be movable toward cable feedthrough 22 for plugging plug connector 2 to mating plug connector 6 in a final plugged position 28 (see Figure 2 ).

  • cable clamping section 50 comprises at least one discontinuation 58 with respect to passage opening 52 in circumferential direction 56, in particular a cable introduction gap 60.

  • Connector position assurance 20 is then rotated by rotation 82 in direction of rotation 92 about axis of rotation 76, as a result of which retaining projection 44 is inserted into retaining groove 72 (see Figure 6 ) and reaches end 80 of the retaining groove (see Figure 7 ). As long as connector position assurance 20 remains in its retaining position 48, lever 30 is accordingly locked in final plugged position 28.
  • Figure 8 illustrates lever 30 in a position 102 which differs only slightly from final plugged position 28 (see Figure 5 ). As is also indicated in Figure 8 , retaining projection 44 in this constellation forms a stop 104 for connector position assurance 20. Housing assembly 1 is therefore configured such that rotation 82 of connector position assurance 20 to retaining position 48 (see Figure 7 ) is blocked when lever 30 of coupling device 26 is not disposed entirely but only in the immediate vicinity of final plugged position 28.
  • a slide (not shown) that is arranged to be displaceable on connector housing 18 may also be provided as coupling device 26 and comprise the retaining projection.
  • the arrangement of retaining groove 72 and retaining projection 44 is of course also possible the other way around. This means that coupling device 26 may comprise retaining groove 72, whereas locking section 70 comprises retaining projection 44.
  • Connector housing 18, connector position assurance 20, and/or coupling device 26 are preferably made of plastic material and/or an electrically insulating material.
