It is also to be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments.

It is to be understood that the terminology used in the description is for the purpose of describing particular embodiments only, and is not intended to be limiting of the invention. All terms used in the specification have the meanings commonly understood by those skilled in the art unless otherwise defined. Well-known functions or constructions may not be described in detail for brevity and clarity.

Fig. 1 is a perspective exploded view of a cable sealing device and a cable sealing system according to an embodiment of the present invention, the cable sealing system comprising a housing wall 20 and a cable sealing device, wherein the housing wall is partially depicted. The housing wall can be a component of a housing of an electrical, optical or electronic device. The device may be, for example, a communication technology device. A set of cables 10 can be introduced into or withdrawn from the housing of the device through the housing wall 20.

The cable sealing device comprises a first plate 1 having a set of first holes 11 and configured for mounting to a first side of a housing wall 20. The set of cables 10 may pass through the set of first holes 11. The cable sealing device comprises a second plate 2 having a set of second holes 12 and configured for mounting to a second side of the housing wall 20 opposite the first side. The set of cables 10 may pass through the set of second holes 12.

The cable sealing device comprises a soft elastic sealing element 3 configured for mounting between one of the first and second plates and the housing wall. In the embodiment shown in fig. 1, the first side is an inner surface of the housing wall and the second side is an outer surface of the housing wall, the sealing element being arranged between the housing wall and the second plate. In addition or alternatively, it is also conceivable for a further sealing element to be arranged between the housing wall and the first plate. The first plate 1 and the second plate 2 can be pressed against each other such that the sealing element 3 can be pressed and elastically deformed, wherein the sealing element 3 can seal and fix the group of cables 10 in the housing wall in the pressed and elastically deformed state.

As shown in fig. 1, the sealing element 3 can be of two-part design, comprising an outer part 3a and an inner part 3b, which can be inserted into a central cavity of the outer part. The sealing element may have a set of third apertures 13 configured for receiving the set of cables 10. At least one of the set of third apertures may be divided by an outer component and an inner component. In the embodiment shown in fig. 1, the sealing element 3 has 9 third holes, 8 of which are divided by the outer part and the inner part, the remaining one being arranged in the inner part 3 b.

The cable sealing device may comprise at least one bolt connection configured for pressing the first and second plates against each other. As shown in fig. 1, the cable sealing device may include a pair of bolt connection devices parallel to each other. The first and second plates 1, 2 and the sealing element 3 may have corresponding receiving holes for receiving bolts 5 of a bolt connection. Alternatively, the bolts of the bolt connection can also be formed integrally with the first or second plate. The bolt 5 of the bolt connection can also be provided with a sealing ring 4 which is designed to be mounted between one of the first and second plates and the housing wall and to seal the bolt in the compressed and elastically deformed state.

As shown in fig. 2, the housing wall 20 may have a set of fourth apertures 14 configured to receive the set of cables 10. The housing wall 20 may have a roof structure 21 protruding from its second side partially enclosing the cable lead-in area with the set of fourth holes. By means of the roof structure, it is possible to substantially prevent falling rain water or the like from entering the cable lead-in area of the housing wall. The housing wall 20 may have a rib structure 23 at its second side surrounding and separating the set of fourth apertures 14. These ribs 23 may facilitate sealing and securing of the sealing element when compressed. The housing wall 20 can have a cylindrical bore 22 for receiving the bolt 5 of the bolt connection, which cylindrical bore 22 projects from the second side of the housing wall 20, against which cylindrical bore the nut 6 of the bolt connection can rest. The amount of compression of the sealing element can be clearly defined by the nut 6 abutting against the cylindrical bore 22, so that a reliable sealing function of the sealing element and a cable fixing function of the sealing element can be ensured.

Fig. 3 is a partial cross-sectional view of a cable sealing device and a cable sealing system according to another embodiment of the present invention. The embodiment according to fig. 3 differs from the embodiment according to fig. 1 primarily in that, instead of a two-part sealing element 3, a plurality of sealing elements 3 are provided, each sealing element being designed as a soft-elastic sealing ring, each sealing ring being designed for one cable of the plurality of cables; the sealing rings 4 for the screw connection and the sealing elements 3 can be arranged on the same side of the housing wall 20; the housing wall 20 does not have a cylindrical bore for the bolt connection. In other respects, reference may be made to the description with reference to fig. 1 and 2.

In the embodiment shown, the number of cables and the number of holes are exemplary. It is also possible, for example, for 2, 3 or more cables to be introduced into the device.
