Abstract

The invention discloses a cable sealing connector used for a ship in a deep water environment. The cable sealing connector comprises a sleeve, a pressing nut, a pressing ring, a sealing ring and a separating disc. The first end of the sleeve is provided with a flange used for connection, the second end of the sleeve is in threaded connection with the pressing nut, the middle section of the sleeve is a small-diameter through hole, the section, close to the first end, of the sleeve is a first large-diameter through hole, the section, close the second end, of the sleeve is a second large-diameter through hole, the pressing ring and the sealing ring are arranged in the second large-diameter through hole and are sequentially located on the inner side of the pressing nut, the separating disc is arranged in the small-diameter through hole, the diameter of the pressing nut, the diameter of the pressing ring, the diameter of the sealing ring and the diameter of the small-diameter through hole are the same and are slightly larger than the outside diameter of a cable used for the ship, and the separating disc is provided with a plurality of through holes which wires penetrate through. According to the cable sealing connector, the structure integrating the sleeve, the pressing nut, the pressing ring and the sealing ring is adopted, a connector of the cable for the ship is sealed so that the connector can bear large enough water pressure, and on the condition that the water pressure is not higher than 20 MPa, it is guaranteed that cables used for the ship and mutually connected are stably sealed and connected.

Description

technical field [0001] The invention relates to a cable sealing connector, in particular to a marine cable sealing connector in deep water environment. Background technique [0002] For marine cables used in deep water environments, when the length of the marine cable is longer than the cable length of a cable drum, a cable sealing connector (a straight-through joint) is required to connect two (or more) marine cables into one. [0003] For the wall-penetrating seal of an object, at present, pressure is applied to rubber seals to deform them to produce a sealing effect. This structure has insufficient water pressure resistance and is difficult to apply to the sealing connection of marine cables in deep water environments. [0004] For example: the Chinese invention patent publication with the patent number "ZL200610057128.7" (disclosure date is September 12, 2007) discloses a sealing device for sealing holes, which is mainly composed of an auxiliary sealing connection device...
