    Short designation: Device for the protected pick-up of cables
    The invention relates to a device for the protection against environmental influences and, if appropriate, the passage of one or more cables and / or cable connectors.
    In the electrical installation in false ceilings, the situation often arises that there is only a few centimeters wide gap between the false ceiling and the ceiling of the building. All electrical cables used to power luminaires in the false ceiling must be inserted and placed in this installation gap.
    Particularly in the case of a built-in situation with a large number of electrical consumers to be built into the system ceiling, as is particularly the case with a large number of lamps, a large number of cables, which are often also connected by means of cable ties, must be connected. be applied in this really narrow gap area.
    For this purpose, built-in boxes are known which contain an at least partially flexible part on or near the bottom thereof. However, these are only applicable to a limited extent, because this receiving part formed by the flexible part for cables and / or cable connectors can only be fitted to a limited extent in the narrow gap between building ceiling and suspended ceiling and therefore only very limited space is available for cables and cable connectors.
    Conventional plastic boxes known in the art for accommodating cable connectors and the cables connected by the cable connectors are not flexible and can therefore not be introduced into the gap region through the openings, which often have only a small diameter, in the gap area.
    Thus, the cables with cable connectors are often placed without further protection in the gap between the building ceiling and the suspended ceiling and are exposed there unprotected to environmental influences such as humidity and possibly temperature and the like. Nor is there any insulation against electrical breakdown.
    On the basis of the above-mentioned prior art, the present invention has for its object to provide a device of the type mentioned in the preamble, which can accommodate one or more cables, also connected with cable connectors, protected against environmental influences and against electric breakdown and which is suitable to be introduced into the space formed between the building ceiling and the suspended ceiling by fitting mounting openings of false ceilings, in order to be accommodated there.
    In order to achieve this object, the invention proposes a device with the features of claim 1.
    According to such a device according to the invention, one or more cables, which are connected with cable connectors, can be introduced into the tubular receiving part of the device and remain there. Due to the plug-shaped caps arranged on the end parts on the front side of the tubular receiving part, the receiving part is protected against environmental influences and is as good as closed. Only the cables to be passed through the plug-shaped caps, avoiding as much as possible contact with, for instance, moisture or further environmental influences of the cable and cable connectors located within the receiving part.
    Because the tubular receiving section is flexible, it can be introduced in a quick and simple manner through the respective mounting opening of the suspended ceiling in the gap area formed between the building ceiling and the suspended ceiling. For this purpose it is first applied to the cable and / or cable connector, subsequently closed by means of the plug-shaped caps and then manually applied in the gap area through the mounting opening. Due to the flexible design of the tubular receptacle, it can also be pressed through quickly and easily through mounting openings with a particularly small diameter without the use of special tools, because the flexible material of the tubular receptacle is bent or bent depending on the installation condition. can be compressed and bent to insert the device into this slit region. The sections for the passage of the cables through the plug-shaped caps in the tubular receiving section can be formed by plug-in seals, sealing rings or the like known per se, which permit the passage of the cables according to an IP protection as required.
    Depending on the application situation, the plug-shaped caps may comprise one or more sections for the passage of the cables. Depending on the diameter of the installation opening, this can also be four or five sections in the form of cable openings.
    In particular, it may be particularly preferred that the tubular receiving portion and the plug-shaped caps have an oval or circular cross section.
    Depending on the installation situation, both the round shape and the oval cross-sectional shape have proved successful. Particularly in the case of a slit area of only a particularly small height, the oval cross-sectional shape appears to be particularly preferable, since several cables can be arranged side by side here.
    Furthermore, it is particularly possible to provide that the flexible, tubular receiving part consists of an elastically deformable plastic, in particular an elastomer such as, for example, rubber.
    In particular, the use of such an elastomer such as, for example, rubber, on the one hand enables the particularly high flexibility during insertion through the mounting opening of the suspended ceiling, and on the other hand it also provides a high temperature resistance and therefore a high flame resistance. In addition, the use of such an elastomer, such as, for example, rubber, provides a particularly high protection against electrical breakdown.
    In addition, it can be particularly preferably provided that each plug-shaped cap has a portion which can be fitted form-fittingly in the respective end on the end face of the tubular receiving portion and sealed against the environment and is connected or connectable there detachably or not releasably.
    Because the plug-shaped caps are inserted positively in the end on the end face of the tube-like receiving section, a particularly effective sealing with respect to these end sections on the end face is obtained, so that penetration of, for example, moisture through this section is completely or largely avoided.
    In addition, it can be particularly preferred that the insertable part of the plug-shaped cap and the respective end have corresponding locking means, such as protrusions, recesses, catches or locking hooks, on the end face of the tubular receiving part, with which the parts are connected or be connectable.
    This enables a particularly secure attachment of the interconnected parts.
    According to a particularly preferred embodiment, it can be particularly preferably provided that the plug-shaped cap is of two-part design, a first part of the cap on the outer jacket of the tubular receiving part and a second part at least partly internally against the inner jacket surface of the tubular receiving part. is arranged adjacent.
    For mounting such two-piece plug-shaped hood, the first portion of the hood is first slid onto the outer jacket of the tubular receiving portion, and then after passing the cable through all parts, including the tubular receiving portion of the second portion of the hood, into the inner jacket surface of the tubular receiving portion is slid until it abuts the end face of the tubular receiving portion with a corresponding outer peripheral edge. Then, the first part of the cap is slid in the direction of the second part on the tubular receiving portion until it is fitted against or behind corresponding locking protrusions of the second part of the cap to remain fixed there by the protrusions. Now, the first-part and second-part plug-shaped cap is particularly effective against the ingress of environmental influences onto the end portion at the head end of the tubular receiving portion and completely or largely seal it against environmental influences.
    In addition, the respective projections ensure that the two-piece plug-shaped cap remains permanently on this end portion.
    In particular, in order to enable a particularly firm fixation of the plug-shaped cap to the end portion of the tubular receiving part, it may preferably be provided that the locking means are formed by outwardly moving from the second part of the cap towards the tubular receiving portion projecting protrusions which, in the assembled state of the tubular receiving portion, press against the first part and, if necessary, engage in recesses formed thereon on the first part and lock there.
    In another solution, which may also be regarded as an independent invention, it is particularly preferred that a hood is formed by a hollow wall box, the hollow wall box comprising a recess, which with the first end part at the front side of the tubular receiving portion is connectable or connectable, the second end portion being connected or connectable on the end face with a plug-shaped cap of the type described above.
    In addition, it may be particularly preferred that the recess of the hollow wall box comprises a connecting section which is connected or connectable to the tubular receiving section in the same manner as the plug-shaped cap, the connecting section at the bottom or on the side wall of the hollow wall box has been applied.
    Here, the cap disposed at one end of the tubular receiving portion is formed by a hollow wall box with a corresponding connecting portion connected or connectable to the tubular receiving portion in the same manner as the plug-shaped cap. This makes it possible to arrange the device with a tubular flexible receiving part at or near the bottom part of a hollow wall box, so that the cable with all cable connectors can be arranged in the tubular receiving part protruding from the box. In the same way, the flexible tubular receiving section can be passed through the mounting opening of the false ceiling and the hollow wall box can subsequently be fastened in the mounting opening or to the mounting opening in a manner known per se.
    The cables and cable connectors located inside the tubular receiving portion connected to the hollow wall box are protected from environmental influences within this portion.
    Finally, it is particularly preferred that the hollow wall box recess has an oval or circular cross section.
    Examples of embodiments of the invention are shown in the figures and described in more detail below.
    In it shows:
    Figure 1 shows a first exemplary embodiment of a device according to the invention viewed from obliquely above in the assembled state;
    Figure 2 the same with a partial interior view;
    Figure 3 the same in a first pre-assembly state;
    Figure 4 the same in a second pre-assembly state;
    Figure 5 shows a hollow wall box according to the invention with tubular receiving part and plug-shaped cap in an exploded view;
    Figure 6 shows a further hollow wall box with round tubular receiving part and plug-shaped cap.
    In the figures, a device 1 for the protection against environmental influences and optionally feeding through one or more cables and / or cable connectors is shown. The device 1 is particularly suitable for passing through mounting openings of false ceilings in the gap formed between the ceiling of the building and the false ceiling. The device 1 has a flexible tubular receiving part 2 for cables and possibly cable connectors. As can be seen in Figures 1 - 4, plug ends 3 can be provided at both end portions on the ends of the tubular receiving portion 2 with portions for feeding the cables into or out of the tubular receiving portion 2. The plug-shaped caps 3 thereby close the tubular receiving portion 2 in the region of its end edges and thus protect the cables and cable connectors which are arranged in the tubular receiving portion 2 from environmental influences.
    Because the tubular receiving portion 2 is flexible, it can be pushed through the mounting opening in a quick and simple manner and reside in the space formed between the ceiling of the building and the recessed ceiling. The cables, and in particular the cable connectors, are shielded within the device against environmental influences and are thus particularly protected against influences of temperature and moisture.
    Due to the flexibility of the tubular receiving part 2, it can also be passed through mounting openings which have only slightly larger diameters than the device 1.
    The devices 1 shown in Figures 1-6 have an oval cross-section, and the device shown in Figure 7 has an approximately circular cross-section.
    In particular, the devices 1 with an oval cross-section can place several cables next to each other and be introduced in a gap between the ceiling of the building and the suspended ceiling with only a small width.
    In the exemplary embodiments, the flexible tubular receiving part 2 consists of an elastomer, for example rubber. Alternatively, the flexible tubular receiving portion 2 may be formed from another elastically deformable plastic.
    In particular, the use of an elastomer such as rubber allows, on the one hand, a particularly great flexibility in the introduction through the mounting opening into the gap area, and on the other hand, the use of such an elastomer ensures that the devices are located in the device 1. cables and cable connectors are protected against environmental influences such as temperature and humidity in particular. In addition, such a material is also flame-resistant to a certain extent and effectively protects against electrical breakdown.
    The cables are inserted into the device 1 through the regions 4 formed on the plug-shaped caps 3. These regions 4 may be formed by per se known plug-in seals or pinch-off nipples or the like, which allow the cables to pass through in accordance with a corresponding IP protection.
    The plug-shaped caps 3 are each by means of a part 5 can be inserted in a positive manner at least partly in the end on the end face of the tubular receiving area and thus be sealed or sealed against environmental influences. brought in. Depending on the exemplary embodiment, these can be connected or detachably connected therewith to the tubular receiving section 2, respectively. be connected.
    In order to enable a firm fixation of the plug-shaped cap 3 on the respective end on the end face of the tubular receiving part 2, locking means, such as for instance protrusions or the like, are formed in particular in the part of the plug-shaped cap to be inserted. which fix the plug-shaped cap 3 on the respective end on the end face of the tubular receiving part 2.
    As can be seen in the figures, the plug-shaped cap 3 is constructed in two parts. Thereby a first part 3a of the cap 3 is arranged on the outer jacket of the tubular receiving part 2 and a second part 3b is arranged at least partly inside, abutting the inner jacket surface of the tubular receiving part 2.
    A firm fastening of the cap 3 on the tubular receiving portion 2 is made possible by the fact that the locking means from the second part of the cap 3 extend outwards in the direction of the tubular receiving portion 2, projections 6 which, in the mounted condition, comprise the tubular receiving portion 2 press against the first part 3a of the hood 3 and thereby fixate there.
    Not shown in the exemplary embodiment, there may also be provided further recesses formed on the first part 3a, in which the locking means engage and possibly lock there.
    For the mounting of such a two-part cap 3, first the first part 3a of the cap 3 is slid onto the tubular receiving part 2, and then the second part 3b of the cap 3 is partly arranged in the tubular receiving part 2. Subsequently, the first part 3a of the cap 3 is slid in the direction of the second part 3b onto the tubular receiving part 2, until it completely overlaps the second part 3b and if necessary is arranged behind the projections 6 of the second part 3b, in order to locked or thus be fixed in this condition.
    The tubular receiving portion 2 is now positively connected to the second part 3b of the cap 3 and fixedly attached thereto and thus sealed against environmental influences.
    As can be seen in particular from Figures 5 and 6, the cap 3 can alternatively be formed by a hollow wall box 7. In addition, the hollow wall box 7 has a recess connectable to or connected to the first end end portion of the tubular receiving portion 2. The second end end portion of the tubular receiving portion 2 is thereby connected to a plug-shaped cap 3. The recess of the hollow wall box 7 thereby comprises a connecting portion 8, which is connected or connectable in the same manner with the tubular receiving portion 2, such as the plug-shaped cap 3. Thereby the connecting part 8, as shown in figure 6, is formed at the bottom of the hollow wall box 7 or, as can be seen in figure 5, mounted on the side wall of the hollow wall box 7. The recess and the tubular receiving portion 2, as shown in Figure 6, may have a circular cross section or, as shown in Figure 5, may have an oval cross section. Such a hollow wall box 7 with a tubular receiving portion 2 arranged thereon can be introduced in the same manner described above simply through the mounting opening of a suspended ceiling into the gap area between the ceiling of the building and the suspended ceiling, whereby parts of the cable and into in particular cable connectors are located inside the tubular receiving portion 2.
    The invention is not limited to the exemplary embodiment, but is manifold variable within the scope of the disclosure.
    All discrete and combined features disclosed in the description and / or drawing are considered essential to the invention.
