Definitions

• the invention relates to a sealing grommet arrangement with a sealing grommet designed as a corrugated tube with a constant outer diameter over its length, one end of which protrudes through an opening in a housing wall and on which a retaining ring for holding the sealing grommet on the housing wall is arranged , which protrudes radially inwards with a radially inner region into a trough of the sealing grommet and which can be connected to the housing wall, closing the opening in the housing wall.
• the object of the invention is therefore to create a sealing sleeve arrangement of the type mentioned at the outset which, with a simple structure and simple assembly, uses the same sealing sleeve for different types of ing of the housing wall allows protruding lengths of the sealing grommet.
• the retaining ring has a central passage opening with the inner contour of which the retaining ring protrudes into a trough of the sealing grommet, the sealing grommet being made of such an elastically deformable material that the retaining ring presses the sealing tion grommet is elastically deforming movable from one trough into an adjacent trough.
• This design makes it possible to use one and the same sealing grommet for different required lengths of the sealing grommet protruding from the housing wall, in that the retaining ring is moved by sliding on the sealing grommet into a trough that corresponds to the desired length protruding from the opening in the housing wall corresponds to the sealing grommet. No additional components or special tools are required for this.
• the retaining ring can also be designed with a different outside diameter, so that the same sealing grommet can be Openings of different diameters in the housing wall can be applied.
• the retaining ring is in contact with the inner contour of its passage opening in the trough of the sealing grommet, the retaining ring is held on the sealing grommet without play.
• the retaining ring can be arranged on the sealing grommet independently of its rotational position and thus to facilitate assembly if the through-opening of the retaining ring has a circular contour.
• the sealing grommet can have a gripping contour on one of its end regions, on which the sealing grommet can be gripped manually and subjected to an axial force, for example.
• the retaining ring can be provided with a connecting structure that can be connected to the housing wall on its outer, radially circumferential area.
• connection structure can be a radially encircling, radially outwardly open annular groove which has a groove width corresponding to the wall thickness of the housing wall and a diameter at the bottom of the annular groove which corresponds to the diameter of the opening in the housing wall.
• the retaining ring is made of an elastically deformable material and its annular groove can be snapped into the opening in the housing wall, the retaining ring can be connected to the opening in the housing wall by simply snapping it into place. If the retaining ring has a radially encircling sealing lip on its radially encircling outer periphery, then in the installed state it bears tightly against the housing wall.
• the sealing lip is designed to be elastic and connected with its radially inner area to the groove wall of the annular groove farther away from the housing wall and with its free-standing radially outer area inclined towards the housing wall, then the retaining ring has the sealing effect when it is mounted on the housing wall increasing with preload on the housing wall.
• the sealing grommet arrangement shown in the figure has a sealing grommet 1 which is designed as a corrugated tube of constant diameter over its length with alternating wave troughs 2 and wave heights 3 .
• the sealing grommet consists of an elastic material. At its left end, the sealing grommet 1 is provided with a tab 4 as a gripping contour, while at its right end it has a kinked socket 5 .
• the nozzle can have any other shape. It can extend straight to the sealing grommet or even be designed to be flexible and bendable in any direction.
• a retaining ring 6 with its central passage opening 7 is arranged in a corrugation trough 2 enclosing the sealing grommet 1 with its inner contour 8 .
• the retaining ring 6 rests with the inner contour 8 of its through-opening 7 with pretension on the outer contour of the corrugation valley 2 on the sealing grommet 1 .
• the retaining ring 6 is shown in a state attached to a housing wall 10, while to the right of it the same retaining rings 6' and 6" are shown in two other possible positions on the sealing grommet 1.
• the retaining ring 6, 6′, 6′′ has on its outer, radially encircling area a radially encircling annular groove 9 that is open radially outwards has a groove width which corresponds to the wall thickness of the housing wall 10 .
• the latter has a diameter which corresponds to the diameter of an opening 12 in the housing wall 10.
• the retaining ring 6.6*6" consists of an elastic material and is positioned on the sealing grommet 1 by snapping it over several corrugation heights 3. By snapping its annular groove 9 into the opening 12 of the housing wall 10, the retaining ring 6 is fastened to the housing wall 10 together with the sealing grommet 1.
• the retaining ring 6, 6*6′′ is provided with a radially encircling sealing lip 13, which is connected with its radially inner region 14 to the groove wall 15 of the annular groove 9 that is farther away from the housing wall 10.
• the sealing lip 13 With its free-standing, radially outer area 16 , the sealing lip 13 is inclined toward the housing wall 10 when it is not installed in the housing wall 10 .
