The cable sealing assembly comprises a tongue-shaped protruding member, an elastic cable sealing member configured to be shaped around the edge of the tongue-shaped protruding member and a corresponding recessed member configured to receive the protruding member and the cable sealing member in between. The elastic cable sealing member has a plurality of through holes forming a single row, each hole configured to have a cable extending there through. The cable sealing assembly is configured to seal the cable entry when the protruding member and the recessed member together apply an even pressure on the cable sealing member. ## Claims ### Claim 1 A cable sealing assembly for a cable entry in a cabinet said cabinet configured to house electronic equipment and including an enclosure and a detachable cover, the cable sealing assembly comprising; a tongue-shaped protruding member; an elastic cable sealing member having a plurality of through holes forming a single row, each hole configured to have a cable extending there through and wherein said cable sealing member is configured to be shaped around the edge of said tongue-shaped protruding member; a corresponding recessed member configured to receive the protruding member and the cable sealing member in between; and wherein the cable sealing assembly is further configured as to seal the cable entry when the protruding member and the recessed member together apply an even pressure on the cable sealing member. ### Claim 2 (depends on 1) A cable sealing assembly as in claim 1 wherein each hole in the cable sealing member is configured with a slit extending from the hole to the exterior of the sealing member as to permit insertion of a cable when pulled apart and wherein each slit is facing the recessed member. ### Claim 3 (depends on 1) A cable sealing assembly as in claim 1 wherein the cable sealing member is a single preformed sealing element. ### Claim 4 (depends on 1) A cable sealing assembly as in claim 1 wherein the cable sealing member comprises a plurality of preformed separate sealing elements located side-by-side, each sealing element comprising at least one hole with a slit. ### Claim 5 (depends on 1) A cable sealing assembly as in claim 1 wherein the cable sealing member comprises a first and a second separate sealing element each sealing element having a plurality of semi-circular cavities in a row and configured as to, when the two sealing elements are put together with the cavities face to face, form a single sealing element with through holes in a row each hole configured to have a cable extending there through. ### Claim 6 (depends on 5) A cable sealing assembly as in claim 5 wherein the first sealing element is attached to the protruding member and the second sealing element is attached to the recessed member. ### Claim 7 (depends on 1) A cable sealing assembly as in claim 1 wherein at least two of the holes in the cable sealing member have different diameters. ### Claim 8 (depends on 1) A cable sealing assembly as in claim 1 wherein the cable sealing member is made of a silicon based material. ### Claim 9 (depends on 8) A cable sealing assembly as in claim 8 wherein the cable sealing member is made of a silicon based material having a flexibility range of A30-A50 on the Shore hardness scale. ### Claim 10 (depends on 1) A cable sealing assembly as in claim 1 wherein the protruding member and the recessed member are made of metal and the cable sealing member is at least partly covered with a conductive layer configured to provide a low impedance path between the protruding member and the recessed member when the cable entry is sealed. ### Claim 11 (depends on 1) A cable sealing assembly as in claim 1 wherein the protruding member is firmly mounted to or being an integral part of the enclosure. ### Claim 12 (depends on 1) A cable sealing assembly as in claim 1 wherein the recessed member is firmly mounted to or being an integral part of the detachable cover. ### Claim 13 (depends on 1) A cabinet comprising a cable sealing assembly as in claim 1 wherein the detachable cover is further configured to engage with the cable sealing assembly so that the protruding member and the recessed member applies an even pressure on the cable sealing member when the cover is mounted.
