    An outer base part with an elongate and in cross-section cup-shaped recess extending across the side of the base part which is intended to face the other module half, and - a plurality of inserts received and mutually superimposed in the recesses of the base part. , which have mutually different radii and which are releasably arranged in each other so that the module half can be adapted by adjusting the number of inserts to wires with different outer diameters, the lower insert being closest to the base part having an outside with a shape corresponding to the shape of the inner surface of the recess of the base member and an opposite inside having a shape corresponding to the shape of the outside of the insert immediately above this bottom post, and each of the other posts having an outside having a shape corresponding to the shape of the inside of the post closest to the post in question.
    The base part and the inserts are made of elastic and compressible material. In addition, the inserts and the inner surface of the recess of the base part are path-shaped with road peaks and road valleys extending in the direction of curvature of the inserts and said inner surface.
    By suitably adjusting the number of inserts in the module halves, the sealing module can be easily adapted at the time of installation to the outer diameter of the pipe around which the sealing module is intended to be applied. The path shape of the posts facilitates a sealing compression of the module halves around the pipe. Due to the shape of the road, the two module halves abut the line via the road tops of the inserts closest to the line, which results in a reduced contact area between the module halves and the line compared with conventional module halves with smooth inserts. Thanks to this reduced contact area, the area of the inserts that need to be compressed is reduced when the module halves are clamped around the line, which in turn reduces the compressive force required to achieve this clamping. The road valleys between the road peaks also give the road peaks an expansion space in the axial direction of the inserts, which also makes it easier to achieve the required compression of the inserts in connection with the module halves being clamped around the line.
    According to an embodiment of the invention, the inserts and the inner surface of the recesses of the base part are provided with mutually cooperating and interlocking projections and recesses which are arranged to prevent a mutual rotational movement between adjacent inserts and between the lower insert and the base part.
    This keeps the inserts in place relative to each other and relative to the base part, which facilitates the handling of the module halves.
    According to another embodiment of the invention, the respective inserts form a pipe half, the inserts of the respective module half being stackable in each other. The waveform of each insert contributes to the insert being able to be designed as a pipe half with a certain degree of dimensional stability even with a relatively small wall thickness of the insert. With such somewhat dimensionally stable inserts, it not only becomes possible to remove individual inserts from the respective base part in a conventional manner in order to increase the radius of the elongate seat in which the line to be sealed is intended to be received, but it also becomes possible to insert a single post in the posts already received in the base part to reduce the radius of this elongated seat if necessary.
    Another embodiment of the invention is characterized by: - that the base part of the respective module half has abutment surfaces on either side of the arcuate recesses of the base part on the side of the base part which is intended to face the base part of the other module half, these abutment surfaces of one the base part of the module half has a shape corresponding to the shape of the corresponding abutment surfaces of the base part of the other module half, - said abutment surfaces of each base part are corrugated with wave crests and wave valleys extending across the longitudinal axis of the arcuate recesses of the base part, and - the axially extending edges of the inserts of the respective module halves have edge surfaces which are corrugated in accordance with the waveform of the abutment surfaces of the base part to form a common corrugated surface together with these corrugated abutment surfaces of the base part.
    The waveform of the said abutment surfaces and edge surfaces facilitates a correct positioning of the module halves relative to each other.
    Other advantageous features of the sealing module according to the invention appear from the dependent claims and the following description.

    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Figs. 1a and 1b illustrate a sealing module 10 according to an embodiment of the present invention for sealing around an elongate conduit 1, such as a pipe, cable or hose, at a bushing in a wall or other structural member. The sealing module 10 comprises in a conventional manner two module halves 11 which are provided with each elongate and in cross-section arcuate seat 12 for receiving the line 1 to be sealed. These seats 12 are arranged together to form a hole extending through the sealing module 10 when the two module halves 11 are fitted against each other with the seats 12 extending opposite each other. The module halves 11 are intended to be fitted against each other with said seats 12 facing each other to enclose the conduit 1 to be sealed, as illustrated in Figs. 1a and 1b. The sealing module 10 is then placed in a holding device 2 (see Figs. 2 and 3) which forms a frame 3 around the sealing module. Via this holding device 2 a radially directed compressive force is exerted against the holding module 10 so that the module halves 11 are pressed against each other and against the jacket surface of the conduit 1 extending through the hole in the sealing module, whereby the module halves 11 are brought into sealing abutment against each other - Laying against the mantle surface of the cable. In the example illustrated in Figs. 2 and 3, the holding device 2 comprises two opposite parts 2a, 2b which are held together and pressed against each other by means of screw means 4. In the illustrated example the sealing module 10 is arranged in a separate holding device 2. As Alternatively, however, two or more sealing modules 10 may be mounted side by side within the frame of a common holding device.
    The respective module half 11 of the sealing module 10 comprises: - an outer base part 20 with an elongate and in cross-section arcuate recess 21 (see Fig. 5), which extends across the side 22 of the base part which is intended to face the other module half , and - a plurality of inserts 30, 30 'received and mutually superimposed in the recesses 21 of the base part which have mutually different radii and which are releasably arranged in each other so that the module half 11 can be adapted to lines with adaptation of the number of inserts 30, 30'. different outer diameters.
    The uppermost insert 30 of the respective module half 11 forms the above-mentioned seat 12 of the module half.
    The base part 20 and the inserts 30, 30 'are made of elastic and compressible material. This elastic material can be a plastic or rubber material and is suitably a thermoplastic. Respective inserts 30, 30 'preferably have a wall thickness of 0.5-2 mm.
    Figs. 6 and 7 show the lowest insert 30 'which is closest to the base part 20. This insert 30' has an outer side 31 with a shape corresponding to the shape of the inner surface 23 of the recess 21 of the base part and an opposite inside 32 with a shape corresponding to the shape of the outside of the post 30 closest to this bottom post 30 '. Each of the other inserts 30 has an outside 31 having a shape corresponding to the shape of the inside 32 of the insert closest to the insert in question, and an inside 32 having a shape corresponding to the shape of the outside 31 of the insert lying closest to the post in question. The lower insert 30 'abuts the inner surface 23 of the recess 21 of the base member over all or at least substantially all of its outside 31, and each of the other inserts 30 abuts the nearest under the lying post over all or at least substantially all of its outside 31.
    According to the invention, the inserts 30, 30 'and the inner surface 23 of the recess 21 of the base part are corrugated with wave peaks 24, 34 and wave valleys 25, 35 extending in the direction of curvature of the inserts 30, 30' and said inner surface 23, i.e. in the circumferential direction. In the illustrated embodiments, the respective wave top 24, 34 has a flat top surface 26, 36 seen in a cross section through the wave top, i.e. seen in a longitudinal section through the base part 20 and the respective inserts 30, 30 ', while respective wave valley 25, 35 has a flat bottom surface 27, 37 seen in a cross section through the wave valley. Between the flat bottom surface 27, 37 of a wave valley and the flat top surface 26, 36 of an adjacent wave peak extends an inclined side surface 28, 38. The wave shape of the inserts 30, 30 'and the inner surface 23 of the base part recess 21 would alternatively be able to have a different design than that illustrated in the attached drawings.
    Respective inserts 30, 30 'form a half of the pipe and show a certain degree of dimensional stability, as illustrated in Figs. 6-9. The inserts 30, 30 'of the respective module half 11 are stackable in each other and the number of inserts of a module half can be adapted depending on the diameter of the conduit 1 to be sealed by removing one or more inserts from the inserts stacked in the base part recesses 21. 30, 30 ', so as to increase the radius of the elongate seat 12 in which the conduit 1 to be sealed is intended to be received, or by inserting one or more inserts into the inserts 30, 30' already received. in the recess 21 of the base part, so as to reduce the radius of said seat 12.
    The inserts 30, 30 'and the inner surface 23 of the recess 21 of the base part are provided with mutually cooperating and interlocking projections 14 and recesses 15 which are arranged to prevent a mutual rotational movement between adjacent inserts 30, 30' and between the lower insert. 30 'and the base part 20. In the illustrated embodiments, the lowest insert 30' on its outer side 31 is provided with recesses 15 which are arranged to engage with corresponding projections 14 on the inner surface 23 of the base. the recess 21 of the lens to prevent a mutual rotational movement between the lower insert 30 'and the base part 20, while each of the other inserts 30 on its outside 31 is provided with recesses 15 which are arranged to engage with corresponding projections 14 on the insole dan 32 of the immediately below the insert to prevent a mutual rotational movement between adjacent inserts. As an alternative, the actual projections could be arranged on the outside of the inserts 30, 30 'for engagement with corresponding recesses arranged on the inner surface of the recess 21 of the base part and on the inside of the inserts.
    The base part 20 of the respective module half 11 has abutment surfaces 29 on either side of the cup-shaped recesses 21 of the base part on the side 22 of the base part which is intended to face the base part of the other module half. These abutment surfaces 29 of the base portion 20 of one module half have a shape corresponding to the shape of the corresponding abutment surfaces of the base portion of the other module half. In the embodiment illustrated in Figs. 1-9, these abutment surfaces 29 are flat, the axially extending edges of the inserts 30, 30 'having flat edge surfaces 39 to form a common flat surface together with the flat abutment surfaces 29 of the insert. associated base member 20. In the embodiment illustrated in Fig. 10, said abutment surfaces 29 of the base members 20 are corrugated with wave crests 24a and wave troughs 25a extending transversely to the longitudinal axis of the cup-shaped recesses 21 of the base members, the axially extending edges of the inserts 30 30 'of the respective module half 11 have edge surfaces 39 which are path-shaped in accordance with the path shape of the abutment surfaces 29 of the base part to form a common path-shaped surface together with these corrugated abutment surfaces 29 of the base part.
    Sealing modules according to the present invention can have widely differing dimensions and can in a smaller variant be dimensioned for sealing narrow wires in the form of, for example, electrical cables and in a larger variant be dimensioned for sealing wider wires in the form of for example sewer pipes.
    In the embodiments illustrated in Figs. 1-5 and 10 and described above, the base part 20 of the respective module half 11 is provided with a single recess 21 for receiving mutually superimposed inserts 30, 30 ”. Thus, in this case, a single sealing module 10 is designed to provide sealing around a single elongate conduit 1. However, the sealing module according to the invention could alternatively be designed to provide sealing around two or more elongate conduits. In the latter case, the base part 20 of the respective module half comprises two or more mutually parallel recesses 21 of the type described above, each of which is designed to receive mutually superimposed inserts 30, 30 'of the type described above to form two or more mutually parallel seats 12 for receiving elongate conduits.
    Figs. 1a and 1b show how a sealing module 10 of the type according to the invention can be fitted in a holding device 2, via which a radially directed compressive force is exerted against the sealing module 10.
    However, a sealing module 10 of the type according to the invention could alternatively be used without such an enclosing holding device 2 and instead be mounted with its jacket surface in direct abutment with the inner hole wall of a hole in a wall or other construction element. In the latter case, an axially directed compressive force is applied to the sealing module 10 via its ends so that the sealing module is compressed in the axial direction and thereby caused to expand in the radial direction outwards to the sealing abutment against the hollow wall on the outside of the sealing module 10 and in the radial direction inwards to the sealing abutment the elongate conduit 1 received between the two module halves 11 of the sealing module 10. In this case, the sealing module 10 must of course be formed with an outer cross-sectional shape corresponding to the cross-sectional shape of the hole in which the sealing module is to be mounted.
    Accordingly, for mounting in a hole with, for example, a round cross-sectional shape, the base part 20 of the respective module half 11 in this case 10 must have a circumferential surface with a semicircular cross-sectional shape. In order to facilitate the axial compression and radial expansion, the base part of the respective module half can in this case advantageously also be corrugated externally on its mantle surface with wave peaks and wave valleys extending in the circumferential direction of the mantle surface.
    The invention is of course in no way limited to the embodiments described above, but a number of possibilities for modifications thereof should be obvious to a person skilled in the art, without this for that reason deviating from the basic idea of the invention as defined in the appended claims. .
