Cable conduit closure

Electrical conductors are laid in tension blocks or pipes when you come to them for checking, Repair, replacement or the like. does not come by simply digging it up, or wants to avoid it. If then If a cable or cable section is to be checked, repaired or replaced, it can be removed from the pull rod or Pull out the cable ducts without having to tear open the pavement, for example. This possibility will but, depending on the type of subsoil, often made very difficult or impossible, that in the guide channels of the stones or pipes earth, sand, mud or the like. penetrates, e.g. slammed in or is shaken by vehicles driving over the pavement. This material can fill the channels so far and / or solidify over time, and clog the channels that the Cables can no longer be pulled out or can only be pulled out with great difficulty. In addition, with the penetrating substances Bricks or other sharp-edged objects that are carried along damage the cable sheath, especially when trying to to pull the cable.

L 233-He LANGMATZ

To avoid these disadvantages, a cable conduit closure for the against the penetrating earth, sand, Sludge and the like sealed entry or exit of Line cables in or from cable pipes and stones known (DE 31 36 239 A1) with a hinge from connected shells formed closure body made of an elastically deformable material and one in the closed State of the interior between the shells filling an insert made of a material compared to the closure body softer material with alternating peaks and valleys.

The innovation is based on the task of sealing the above-described cable conduit closure of the cable pipe, especially with regard to the penetration of stones and the like Objects that can damage the cable as mentioned, and possibly with regard to a

greater tolerance with respect to the diameter and wall thickness of the sealable with one and the same closure size Pipes or stones, but watertightness is not required, rather the ingress of smaller amounts of water to cool the cables can be quite desirable.

This object is achieved according to the innovation in that the end faces of the closure body by the ends of the shells forming it, preferably wave-shaped, semicircular transverse walls consist of elastically deformable material.

L 233-He LANGMATZ

To the greater tolerance with regard to the pipe diameter to be sealed with one and the same cable conduit closure size and to achieve wall thicknesses, the jacket of the closure body can be conical and protruding radially Ribs made of elastic material should be provided, which when pushed into the pipe end of the respective diameter deform accordingly.

In addition, the jacket of the closure body can have openings, preferably in the form of a central hole outgoing cross-shaped or star-shaped slots for clamping the inside of the closure body filling Have insert made of soft material with alternating elevations and depressions.

By closing the in the known cable conduit closure open end faces of the closure body by transverse walls from one opposite the inside of the The filler material located in the closure body is much firmer, albeit elastic material, the penetration of stones and similar sharp-edged objects along the cable surrounded by the cable conduit closure crucially obstructed in the pipe interior, so that a clogging of the pipe is practical even over long periods of time is excluded.

The resilient ribs protruding radially outward from the jacket of the closure body can be when Insertion of the closure into the end of a conduit

elastically deform and larger pipe diameter differences compensate as this was possible with the known cable conduit closure, where the tolerance is only from the Conicity and the elasticity of the material of the closure body resulted, both in the execution according to the Innovation are also present.

The innovation is described in more detail below with reference to the drawing. Since the innovation only affects the closure body, does not, however, refer to the insert already dealt with in the prior art, the latter is for reasons not shown for clarity and simplicity. They represent:

1 shows a side view of the cable pipe closure with closed shells; FIG. 2 is a view in the direction of arrow II in FIG

Fig. 1;

3 shows an interior view of the opened shells and FIG. 4 shows a section along the line IV-IV in

Fig. 3.

The closure body 1 consists, as is known, of two half-shells, namely the shells 2 and 3} but, in contrast to the known design, it is not open at its ends, but rather by semicircular sector-shaped transverse walls 4, 5, 6 and 7, which are provided at the ends of the shells are locked. The transverse walls are preferably made of the same elastically deformable

Material like the trays 2 land 3 to get around through the To be able to put cables around the lock.

The transverse walls are designed to be corrugated in order to increase the elasticity, whereby the corrugations, as with the Walls 6 and 7 are shown to be symmetrical or, as shown in the case of walls 4 and 5, to be asymmetrical can. The different representation of the corrugations is only used for clarification. In practice, of course all transverse walls are corrugated symmetrically or asymmetrically in the same way.

As is known, the two shells 2 and 3 are connected by pilm hinges 8.

In order to have a greater tolerance of the pipe diameter and wall thicknesses that can be closed with a closure size as well To achieve a good seal, the jacket 9 of the closure body 1 is conical and with radial ribs 10 or 11 made of elastic material, some of which 10 extend around the entire circumference of the closure body, while the other 11 only in the area of the hinges 8 are provided.

In order to connect the insert to the sleeve body, this can be provided with openings 12, which from starting from a central hole 13 cross-shaped or star-shaped Slots 14 exist. The soft material of the insert is thereby spreading open the slots 14 in the openings 12 wedged in and held by the re-closing slits.
