Abstract: The invention relates to a cable sealing device comprising: a first plate having a group of first holes and configured to be mounted to a first side of a housing wall; a second plate having a group of second holes and configured to be mounted to a second side of a housing wall; and a soft elastic sealing element configured to be mounted between one of the first and second plates and the housing wall. The group of first holes and the group of second holes and the sealing element are configured to receive a group of cables, and the first and the second plate can be biased toward each other, so that the sealing element can be pressed and elastically deformed. The sealing element can seal and fix the group of cables in the housing wall in a pressed and elastically deformed status. The invention also relates to a cable sealing system comprising a housing wall and the cable sealing device. The cable sealing device is simple in structure and easy to assemble, and can ensure good sealing and fixing of the cables.
