SK81393A3 - Sealing element of slab loadable from front side into a pipe for a cable line - Google Patents

Abstract

The invention proposes a sealing element (1,2) for cable conduits (3), which sealing element can be inserted into said conduits (3) at the end and makes it possible to seal such cable conduits such that they are proof against drifting sand, the housing (1) of the sealing element being tapered conically in the insertion direction, having an outer collar (1a) and being fitted with a plate (2) which consists of foam (which has open pores and is permanently elastic) and whose external diameter before insertion into the housing is considerably greater than its internal diameter and which has pre-cut separable stamped-out regions (2a, 2b, 2c) for accommodating at least one cable.

Description

Plastic sealing element insertable from the front into the cable routing tube

Technical field

The invention relates to a sealing element made of plastic, which can be inserted from the front into a cable guide tube.

BACKGROUND OF THE INVENTION

Such sealing elements are necessary for sealing cable routing pipes in which cables are laid transversely below the path of the road. As a rule, more cables are laid in the cable guide tube. The sealing element required for sealing the cable guide tube is intended to seal the inlet opening of the cables or cables into the pipe against the sand to be deposited, in order to prevent the cables in the pipe below the path from becoming entangled. The pressure stages of the tubes used may be different.

SUMMARY OF THE INVENTION

The object is achieved by a sealing element according to the invention, the nature of which is described in the characterizing part of the main claim.

The advantage of the solution according to the invention lies in particular in the fact that an easy-to-handle sealing element is available at the construction site, which can be adapted to different circumstances, for example the number of cables of different diameters, cable guide tubes of different diameters. , without incurring additional costs. Due to the conicity of the housing shell, it is prevented that the sealing element is not forced outwards. Since the sheath is provided with cut-outs or grooves, the sleeve can easily be bent over the cable or cables. The desired breaking point provided in the tube axis direction provides the advantage that the sleeve can be easily adapted to the various inner diameters of the tubes. The inner collar and the grille provided at the bottom of the housing prevent the open-pored cellular sheet from being pushed inside the tube. By placing the grid separating points in the inner collar cutouts, it is advantageous to prevent the cable sheath from being damaged by the cutting edges of the dividing points. Another advantage lies in the use of a lightweight porous mass on the sealing plate. In this way, it is achieved that water which has penetrated into the tube can leak out again.

Overview of the figures in the drawing

The invention is explained in more detail below by way of example with reference to the drawing.

In FIG. 1 is an exploded view. In FIG. 2 is a bottom plan view of the housing.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1, the plate 2 shown above, formed of an open-pored cellular mass, has a disc shape and consists of a permanently elastic material. Its diameter is substantially greater than the corresponding inner diameter of the conical housing 7 of the sealing element shown below. The plate 2 has detachable moldings 2a, 2b, 2c for receiving one or more cables. This plate 2 is inserted into the housing 1 from above while being compressed, thereby obtaining a corresponding sealing effect.

In FIG. 1, a finished assembled sealing element on the cable guide tube 3 is shown in the lower third.

As can be seen from FIG. 2, the housing 1 has an outer collar 1 a. which at the same time serves as a stop when inserted into the cable guide tube 3. The housing M of the housing 1 has a side cut-out 1b and a desired breakage point 1c. In this way, the sleeve can also be bent over the cable and can be adapted to the various inner diameters of the tube. The housing 1 also has a lower collar 1d as a stop on the plate

2. The bottom of the housing 1 is formed by a grid 1e which corresponds to the diameters of the cables to be laid and remains either as a whole or only in parts or can be completely removed. For this purpose, the breakpoint locations 11i are provided on the sheath M, which are arranged recessed in the recesses of the inner collar 1d, so that, in the event of separation, the excess sheaths of the material do not damage the cable sheaths.

Claims (3)

Plastic sealing element insertable from the front side into a cable guide tube, characterized in that it is both formed of a pot and also of a housing (1) with a cut-out (1b) The housing (M), which is formed from the outer collar 1a) to its bottom in the form of a cone, has, on the one hand, a laterally fixed point of the desired break, and on the other hand has a collar (ld) and a grid (le). ), which together form an annular plate (2) of permanently flexible open-pored cellular material having separable moldings (2a, 2b, 2c) for guiding at least one cable (4) and inserted until it stops on the outer collar (1a) into the cable guide tube (3) Sealing element according to Claim 1, characterized in that the grille (1e) has at the housing (M) of the sleeve (1) the required break points (1f), which are arranged recessed in the recesses of the collar (1d). Sealing element according to claims 1 and 2, characterized in that the lightweight mass plate (2) has a substantially larger outer diameter than the inner diameter of the housing (1).
