Description
FIELD OF THE INVENTION
[0001] The invention pertains to a fixable flange gasket for
sealing a housing that is provided with a flange and needs to be
connected to a wall cutout or another connecting flange.
BACKGROUND OF THE INVENTION
[0002] A flange gasket of this type is used for installing a
housing or the like that is provided with a flange in any desired
fitting position, namely such that the required mounting screws
cannot fall out of the mounting holes.
[0003] It is common practice to cut flange gaskets of this type
such that they are precisely fitted to the respective flange,
wherein the openings for the mounting screws correspond to those in
the flange. This means that the mounting screws for rigidly
connecting the flanges can be effortlessly pushed through these
openings.
[0004] However, the installation in any desired fitting position is
quite difficult with a thusly designed flange gasket because the
object to be mounted, the flange gasket and the mounting screws
need to be somehow held together and mounted with the aid of the
mounting screws.
SUMMARY OF THE INVENTION
[0005] The invention is based on the objective of designing a
flange gasket of the initially described type for use on a housing
in such a way that the installation is simplified by holding the
mounting screws in the openings in the flange gasket.
[0006] According to the invention, this objective is attained in
that collars protruding from the plane of the flange [gasket]
material are arranged on the flange gasket in the region of the
flange mounting holes, and in that the mounting screws can be
inserted into the openings of said collars.
[0007] Advantageous embodiments of invention are disclosed in
Claims 2-5.
[0008] The advantages attained with the invention can be seen, in
particular, in that the housing and the flange gasket with the
mounting screws pre-installed therein form a unit that can be
installed in any desired installation or fitting position, namely
because the mounting screws are prevented from falling out of the
mounting holes of the flange even if the unit is installed
overhead.
[0009] The mounting screws can be advantageously inserted into the
openings of the collars that protrude from the plane of the flange
gasket material and are arranged congruently with the mounting
holes in the flange.
[0010] It is also advantageous to provide at least one sealing lip
on the inner wall of the collars in order to secure the mounting
screws from falling out.
[0011] The mounting holes corresponding to the respective collars
of the flange gasket have a correspondingly adapted or widened
diameter such that the flange gasket is already held in the
mounting holes when it is joined with the flange. It is also
proposed to manufacture the flange gasket in the form of a moulded
article in order to allow the utilization of optimal materials.
[0012] The screws and the flange gasket are fixed on the flange of
a connector housing that is not described in greater detail such
that the installation of such a housing on a corresponding mounting
part is significantly simplified.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] One embodiment of the invention is illustrated in the
figures and described in greater detail below. The figures
show:
[0014] FIG. 1, a perspective representation of a flanged connector
housing and a flange gasket spaced apart therefrom;
[0015] FIG. 2, a perspective representation of a flange gasket with
a flange housing spaced apart therefrom, and
[0016] FIG. 3, a section through a mounting hole in the flanged
housing with a mounting screw inserted therein.
DETAILED DESCRIPTION OF THE INVENTION
[0017] FIG. 1 shows a connector housing 1 with a flange 2 in the
form of a perspective representation of the open connecting side of
the connector.
[0018] Due to the chosen viewing angle, a flange gasket 7 is
visible behind the housing 1, wherein this flange gasket serves for
producing an absolutely tight connection with a not-shown housing
or another flange. In addition to the cutout 8 for the cables
leading out of the connector, the flange gasket 7 also contains
openings 10 for mounting screws that are respectively surrounded by
a collar 11 protruding from the material plane 9 of the flange
gasket 7.
[0019] This figure also shows a clip 6 for producing a separable
connection with a not-shown mating connector.
[0020] FIG. 2 also shows a perspective representation, however, of
the opposite side of the flange gasket 7 and the housing 1 referred
to FIG. 1.
[0021] This figure clearly shows the cutout 8 as well as the
arrangement of the openings 10 in the flange gasket 7.
[0022] The mounting holes 3 in the flange 2 of the housing for
accommodating the mounting screws are provided with a region 4 of
increased diameter, wherein the collar 11 of the flange gasket 7
protrudes into this widened region. In this case, the diameters of
the opening 4 and of the collar 11 are chosen such that the flange
gasket is already fixed on the flange when the collars are inserted
into the openings 4.
[0023] FIG. 3 shows an enlarged partial section through one of the
mounting holes 3 in the flange 2 with a mounting screw 5 inserted
therein.
[0024] The flange gasket 7 is placed on the flange 2 of the housing
1 in a precisely fitted fashion, wherein the collars 11 of the
flange gasket penetrate into the widened regions 4 of the mounting
holes 3 in the flange. These widened regions 4 are absolutely
imperative for a thusly designed flange gasket.
[0025] FIG. 3 also shows an inner sealing lip 13 that is integrally
moulded onto the collar end 12 and tightly adjoins the shaft of the
mounting screw 5 such the mounting screw is prevented from falling
out and a sealing effect is simultaneously achieved.
