Embodiment 1

[0043] A waterproof device for underwater brittle uncut cables, including waterproof studs 1 for inner connections, outer connecting plates 2, protective jackets 4, waterproof gaskets 3, sealing rings a8, sealing rings b9, and sealing rings c10, Wherein, the outer connecting plate 2 is fixed on the waterproof cover, and plays the role of connecting the waterproof cover. The inner connection waterproof stud 1 is screwed on the outer connection plate 2 to play the role of connecting and fixing the cables. The waterproof gasket 3 is placed on the top of the internally connected waterproof stud 1 to enhance its waterproof ability, and the protective overcoat 4 covers the top of the entire internally connected waterproof stud 1 to play a major role in waterproofing. The sealing ring a8, the sealing ring b9, and the sealing ring c10 are placed on their corresponding annular grooves to ensure the waterproof performance of the entire device. Through the above setting, the cable is ac...

Abstract

The invention discloses an underwater brittle non-cuttable cable penetrating connection waterproof device, which comprises an inner connection waterproof stud, an outer connection plate, a waterproof gasket and a protective jacket. The internal connection waterproof stud is a hollow stud with an external thread section arranged close to one end and the inner diameter matches the outer diameter of the cable; the outer connecting plate includes a connecting column; the protective jacket includes a protective outer cylinder; the connecting column and the protective outer cylinder are coaxial It is set and located on the outer side of the protective outer cylinder, and the connecting column is connected with the adjacent end of the protective jacket. The external threaded section of the internally connected waterproof stud passes through the protective outer cylinder and is connected with the internal thread of the connecting column; the opposite end of the externally threaded section of the internally connected waterproof stud is located in the protected external cylinder and is equipped with a waterproof gasket. The protective outer cylinder on the outside of the waterproof gasket is filled with waterproof glue. Therefore, the present invention can effectively form a complete protection between the cable and the waterproof cover, greatly improving the waterproof performance of the connection device, avoiding cable damage caused by cable bending, and facilitating later maintenance.

Description

technical field [0001] The invention relates to a waterproof device for penetrating a brittle and uncut cable under water, and belongs to the technical field of connectors. Background technique [0002] The underwater connection device is a connection device that can be applied in an underwater environment to provide a safe and reliable connection. In recent years, with the application of underwater robots and underwater welding technology more and more widely, the demand for underwater connection device technology is becoming more and more urgent, especially for the underwater cabin-penetrating sealing connection device for brittle cables. is urgent. However, the current brittle cable underwater penetration seal connector has disadvantages such as poor sealing, short service life or easy damage to the cable. Contents of the invention [0003] Based on the deficiencies of the prior art, the present invention proposes an underwater brittle and uncut cable penetration wate...
