Description

Overhead line house connection box

The innovation relates to a frex line house connection box, which is attached to a roof stand, with the cable entry takes place in the house connection box through a coaming which is arranged at the bottom of the house connection box and engages in a hole in the roof stand tube, with in the roof stand tube lying spacers to fix the individual cables or the ribbon cable and where the cable entry is by means of Seal and pressure plate can be sealed.

Such overhead line house connection boxes have been for many years as so-called S-version known (German utility model 1 981 898) of the applicant).

This design has proven itself well. Only at the cable entry to the. House connection box out, this version is still dependent on the assembly accuracy, which concerns the insulation. It can happen that the last spacer is not deep enough in this area, so that there is then the possibility that the distance between the conductors and thus the insulation is endangered if this last spacer is too far apart from the point of introduction, a conductor is in contact with the roof stand tube or two conductors are in contact.

The innovation has set itself the task of an overhead line house connection box of the type mentioned at the beginning so that the distancing of the lines, also in the area of the line entry to the house connection box, can be safely carried out by simple measures and means.

The object is achieved according to the invention in that the The spacer washer closest to the cable entry opening can be joined together with a spacer to form a structural unit and that this structural unit is one from the line entry opening has usable or controllable centering device. This has the advantage that the isolation - and thus short-circuit protection and fire resistance - also in the cable entry and the area of curvature of the lines from the roof stand tube to the house connection box is fully effective and maintains and that the correct position of the components can be checked from the front of the house connection box.

Components that strive for the same goal are also known for a long time from German Patent 1 095 338, but not in US Pat Realized in practice, since the processes described therein (e.g. welding or gluing of insulating tubes to form a structural unit) are still too complicated. In addition, too many components are still required, such as connecting sleeves, pipe bends, splash bodies etc. are required, which are still not standardized or commercially available components for overhead line house connection boxes.

According to a further feature of the innovation, the spacer and the Spacer can be joined together by a holding device. This holding device can be designed to be snapped or screwed be, with resilient extensions and in the snap version there is an opening that latches behind the extensions and the extensions of the holding device preferably through the one in the center the existing opening protrude through the bistance disc.

In a simple manner, the spacer has line-separating ends Walls and is designed as a part of the chamber. It can be a Have a semi-cylindrical shape and a central web on which the extensions are attached, wherein the central web has at least a single cavity. Such a structural part is cheap manufacturable.

Another feature of the innovation is the centering device with the lower part of the house connection box in the course of assembly, i.e. with the correct position of the spacer to the Cable entry opening screwed with screws or the like or controllable and to be preloaded through a seal formed sealable.

The centering device can, however, in a preferred embodiment example protrude into the line inlet opening and the Inevitability can be achieved by means of latching means such as centering pins, centering brackets or the like, ie from the inside the house connection box can be used. This version has the advantage that the correct position of the last spacer is linked to the design by simple measures is.

It is advantageous to have the centering pin on the centering device when using single conductors or ribbon conductors

In FIG. 1, individual lines are drawn as lines, which lead from the last spacer 2 into the grommet 17 of the line entry opening 1. Flat ribbon conductors can also be used. A spacer 4 is attached to this spacer 2 and can be joined to it by a simple holding device 5, 5 ^f . A centering device 12, 16 makes it easy to see the correct position of the spacer when inserting the cable harness into the roof stand tube, since this centering device 5, 5 * can be inserted from the conduit opening 1. The holding device for joining spacer 2 and spacer 4 can, in the simplest case, consist of one or two openings 5 * located in the center of the spacer and resilient extensions 5 »which are molded onto spacer 4 Assembly snapped into this last spacer 2 and forms a structural unit with it. In the chamber-like part 7, lines separating walls are designated by 4 * and 4 ", and FIG. 4 clearly shows that the spacer part 4 can expediently have a semi- cylindrical shape A control conductor can be carried out in an insulating manner in the hollow space. A further control conductor can also be placed above the hollow space «

An inevitable assembly is now achieved in a simple manner by the centering device. According to FIG. 3, a preferred form is that a centering pin 12 is used. This can be used after installation of the line from the inside of the house connection box and can be made so long that it is in

the box protrudes. This centering pin 12 is in a centering opening 11 insertable. The bracket is done by resilient Approaches 12 *. The centering opening 11 itself can be attached in the central web 8 of the spacer part 4. The centering pin can - depending on the type of cable, individual cables or ribbon cable in the center of the cable entry opening 1 or above this center. The centering pin is secured by a seal 15 sealable. The existing seal 14 below the pressure plate can also be used as a seal (Fig. 1). Another form of centering device can be created in such a way that screws 16 are used, which at the same time the fastening screws of the pressure plate 13 can be. In '£' - 1 and 2, the screw head can be seen here in each case. The counter threads of these screws are in this case in the spacer part 4, which is non-positively connected to the box bottom 18 by the pressure plate 13 »or the screws 16. A seal 14 is located between the bottom 18 and the pressure plate 13 in a known manner.

In this embodiment, the inevitability is also given, since the fitter cannot omit the spacer 4, otherwise the pressure plate cannot be fastened by the screws 16. Another possibility, an inevitability through simple measures To bring about, there is still that the spacer 2, together with the spacer 4, created in one piece will.
