Abstract

The invention relates to an environmentally sealed plug-in connector housing formed from a base body ( 2 ) having a fastening flange ( 10 ) molded thereon. The fastening flange ( 10 ) is associated with a sealing element ( 20 ) that is compressed in a sealing manner between the fastening flange ( 10 ) and an assembly surface ( 3 ). In order to ensure the sealing of fastening bores ( 11 ) provided in the fastening flange ( 10 ), sealing sleeves ( 21 ) are molded onto the sealing element ( 20 ), which sealing sleeves extend into the fastening bores ( 11 ) and at least completely pass through the latter. A fastening screw inserted into a fastening bore ( 11 ) can in this way seal with its screw head the fastening bore ( 11 ) by means of the sealing sleeve ( 21 ) that is compressed by the screw head.

First claim

The invention claimed is:

1. A plug-in connector housing ( 1 ) comprising a base body ( 2 ) and
a fastening flange ( 10 ) molded onto the base body ( 2 ), said plug-in connector housing mountable to an assembly surface through said fastening flange ( 10 ),
wherein the fastening flange ( 10 ) has at least one fastening bore ( 11 ), and
wherein the fastening flange ( 10 ) has a side that faces away from the base body ( 2 ), wherein a sealing element ( 20 ) that approximately corresponds to the shape of the fastening flange ( 10 ) is received by and retained by the fastening flange ( 10 ) on the side that faces away from the base body ( 2 ),
wherein the sealing element ( 20 ) has at least one sleeve-shaped attachment molded thereon that forms a non-segmented sealing sleeve ( 21 ),
wherein the sealing sleeve ( 21 ) is provided in the fastening bore ( 11 ) of the fastening flange,
wherein the sealing sleeve ( 21 ) at least completely passes through the fastening bore ( 11 ), so that the sealing sleeve ( 21 ) protrudes from the fastening bore ( 11 ) in a non-mounted condition of the plug-in connector housing ( 1 ),
wherein the fastening bore ( 11 ) is tapered radially inward from the side of the fastening flange ( 10 ) that faces away from the base body ( 2 ) towards the a side of the fastening flange ( 10 ) that faces the base body ( 2 ).

2. The plug-in connector housing ( 1 ) according to claim 1 ,
wherein the at least one fastening bore ( 11 ) is conically tapered.

3. The plug-in connector housing ( 1 ) according to claim 2 ,
wherein an external contour of the sealing sleeve ( 21 ) has a conical shape that corresponds to a shape of the fastening bore ( 11 ).

4. The plug-in connector housing ( 1 ) according to claim 1 ,
wherein the fastening flange ( 10 ) has molded thereto a peripheral collar ( 12 ), wherein the peripheral collar ( 12 ) extends away from the base body ( 2 ).

5. The plug-in connector housing ( 1 ) according to claim 4 ,
wherein the peripheral collar ( 12 ) surrounds the sealing element ( 20 ).

6. The plug-in connector housing ( 1 ) according to claim 4 ,
wherein the peripheral collar ( 12 ) is thinner than the sealing element ( 20 ).

7. The plug-in connector housing ( 1 ) according to claim 1 ,
wherein the sealing element ( 20 ) has, on a side facing away from the fastening flange ( 10 ), at least one sealing lip ( 22 ) that extends in in a manner that corresponds to a shape of the sealing element ( 20 ).

8. The plug-in connector housing ( 1 ) according to claim 7 ,
wherein the sealing element ( 20 ) has two sealing lips ( 22 , 22 ′), wherein a first sealing lip ( 22 ) extends along an outer edge of the sealing element ( 20 ) and a second sealing lip ( 22 ′) extends along an inner edge of the sealing element ( 20 ).

9. The plug-in connector housing ( 1 ) according to claim 7 ,
wherein the sealing element ( 20 ) has molded thereon on the side facing away from the fastening flange ( 10 ) at least one support ring ( 24 ) that is located in an area of the sealing sleeve ( 21 ) that is provided on a side of the sealing element facing the fastening flange, wherein the support ring ( 24 ) has a diameter that approximately corresponds to a diameter of the sealing sleeve ( 21 ) and has a height that approximately corresponds to a height of the sealing lip ( 22 ).

10. The plug-in connector housing ( 1 ) according to claim 1 ,
wherein the fastening flange ( 10 ) has at least one projection ( 13 ) on the side facing away from the base body, wherein the at least one projection ( 13 ) engages in a corresponding recess ( 23 ) of the sealing element ( 20 ).

11. The plug-in connector housing ( 1 ) according to claim 1 ,
wherein the sealing element ( 20 ) is made from an elastic sealing material.

12. The plug-in connector housing ( 1 ) according to claim 1 ,
wherein the sealing sleeve ( 21 ) protrudes from the fastening bore ( 11 ) by 0.05 mm to 1.0 mm when the plug-in connector housing ( 1 ) is in a non-mounted condition.
