TITLE: Module and.Frame for Cable Entries

Technical Field
The present invention concerns a module and frame for
cable entries, pipe penetrations etc.

Prior Art
Frames of different kinds are normally used for cable
entries, pipe penetrations etc. The frame may receive ca-
bles for electricity, communication, computers etc. or
pipes for different gases or liquids such as water, com-
pressed air, hydraulic fluid and cooking gas. It is used in
many different environments, such as for cabinets, techni-'
cal shelters, junction boxes and machines and also decks
and bulkheads of ships. The frames may also be mounted in
walls or roofs of different types of buildings.
Different modules adapted to the cables or pipes to
be received are normally included in the frames. However,
these modules are normally only adapted to cables, pipes or
the like having a circular cross section. There are no spe-
cial modules for flat cables or the like. When receiving
flat cables it has been common to make special arrangements
in each frame. The person mounting the cables, pipes or the
like has made the adaptation. Thereby the result has in
some degree been depending on the skill of the person
mounting the cables etc. Thus, there is a need of modules
that may be readily adapted to the flat cables or the like
to be received in the frame.

Summary of the Invention
The invention is developed concerning parts not hav-
ing a circular cross section, e.g. flat cables. One object

of the present invention is that the frame should be possi-
ble to adapt to the cross section of the part to be re-
ceived.
This object is meet by a module to be received in a
frame for cable entries, pipe penetrations etc. The module
has parts adaptable to receive flat cables or the like,
having an elongated cross section.
A further object of the present invention is that
handling should be improved, concerning mounting., storing
as well as transport.
The modules used are preferably adaptable to cables
of different dimensions, by means of peelable sheets. The
sheets are held together by an adhesive effect. The adhe-
sive effect is strong enough to normally keep the sheets
together, but not stronger than making it possible to peel
off a separate sheet by hand.
Further objects and advantages of the present inven-
tion will be obvious for a person skilled in the art when
reading the detailed description of at present preferred
embodiments below.
In one aspect, the invention provides a module to be
received in a frame for cable entries and/or pipe
penetrations, the module comprising:
two end parts; and

two middle parts placed between the end parts to receive
flat cables and/or pipes having an elongated cross section,
wherein each middle part is formed of a base plate and a
number of sheets that may be peeled off to adapt the middle
part to the flat cable or the flat pipe to be received.

Brief Description of the Drawings
The invention will be described further below by way
of examples and with reference to the enclosed drawings.

Detailed Description of Preferred Embodiments
In Fig. 1 a frame 1 for cable entries, pipe penetra-
tions etc. is shown. The frame 1 is to be received in a
wall, top, roof etc. As is known in the art a number of
modules 2, 3 are received in the frame 1. The modules 2,3
are made of an elastic material. In order to give a tight

seal a wedge 4 or other tensioning means is arranged to put
pressure on the modules 2, 3, which will expand outwardly
due to the pressure. Between each set of modules 2, 3 a
partition 5 is arranged. The partitions 5 are arranged in
such a way that they may slide in the frame 1, due to the
pressure exerted by the wedge 4.
Of the shown modules 2, 3 one type of module 2 is for
cables, pipes or the like having a circular outer circum-
ference. This type of module is well known in the art and
will not be described extensively here. The other module 3
is to receive flat cables 6 or other parts having an elon-
gated and rounded outer circumference.
Even though the flat cables 6 are shown in Fig. 1
having a cross section with rounded, semicircular ends, a
person skilled in the art realises that the flat cables 6
may have other cross section forms. The present invention
has proved useful also for flat cables having a more or
less rectangular cross section. The corners of the cross
section of the cable often being somewhat rounded. The lat-
ter cases function due to the fact that the modules 3 are
elastic enough to take up the deviating cross sections.
Thus, end parts 7 having a rounded inner surface facing the
cable may be used even if the opposing surface of the cable
is virtually straight.
The module 3 for flat cables 6 has two end parts 7,
which may correspond to or be identical with the parts of
the module 2 for cables etc. having a circular cross sec-
tion. Between the end parts 7 two middle parts 8 are ar-
ranged. The end parts 7 have a number of sheets 9 that may
be peeled of to adapt the end parts 7 to the part to be re-
ceived. In the same way the middle parts 8 have sheets 10
that may be peeled off. Further, each middle part 8 has a
base plate 11. The base plate 11 is placed at the side of
the middle part 8 that is to be directed away from the ca-
ble 6 or the like at mounting. The end parts 7 have base

units 14 having a rectangular outer configuration and a
circular inner configuration. The circular inner configu-
ration is to receive a cable, pipe or the like. The peeling
sheets 9 are received on the inside of the circular part.
Depending on the dimensions of the flat cable 6 the
middle parts 8 of the module 3 may have varying length.
Usually it is enough to have a number of standard lengths
for the middle parts 8. It is also possible to have middle
parts 8 that are relatively long, in which case the middle
parts are cut to an appropriate length before mounting.
When the end parts 7 are used for a module 2 with
circular inner cross section, a blind rod 12 is usually
furnished to facilitate storing, transport and mounting. In
the modules 3 for flat cables 6 the blind rod 12 is re-
placed with a blind plate 13 placed between the middle
parts 8. The blind plate 13 has rounded ends to be received
in the end parts 7. In some embodiments there are no blind
plates 13.
As mentioned above identical units may be used for
the modules 2 for circular cables, pipes etc. and for the
end parts 7 of the modules 3 for flat cables or the like.
The use of identical units facilitates handling and stor-
ing.
In use the blind plate 13 is first taken away when a
flat cable 6 or the like is to be brought through the frame
1. Then the appropriate number of sheets 9, 10 are peeled
off from the end parts 7 and middle parts 8, respectively.
The appropriate number of sheets 9, 10 is that number that
is needed to give room for the flat cable 6 in the module
3. When the cables, pipes or the like have been mounted in
the frame 1 the wedge 4 or other tensioning means is ma-
nipulated to put pressure on the modules 2, 3 having ca-
bles, pipes, blinds 11, 12 etc. Due to the pressure exerted
by the wedge 4 or the like the elastic material of the mod-

ules will expand in the other directions, giving a tight
seal.
