A cable tensile connection structure and a load-bearing watertight connector using the structure

Abstract

A cable tensile connection structure and a load-bearing watertight connector using the structure, the cable tensile connection structure mainly includes an intermediate sleeve, a central sleeve, mounting screws, spring washers and a pressure plate, and the load-bearing watertight connector includes In addition to the tensile connection structure, it also includes a shell, a tail sleeve, a set screw with a tapered end, a first sealing ring, a central conductor, and an intermediate conductor assembly. Through the implementation of the present invention, a load-bearing coaxial cable with a load-bearing rope and a sealed protective layer added outside the coaxial wire is used, and the load-bearing cable is used to connect the water extension to the underwater extension, and the water extension can be connected through a single cable. Realize the direct energy supply and control of the underwater extension, and at the same time, a special waterproof structure is set on the connector, and most of the key components are connected by screw connection and interference fit, which greatly improves the waterproof of the connector performance.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a cable tensile connection structure and a load-bearing watertight connector using the structure. Background technique [0002] At present, with the promotion and implementation of the national marine strategy, there is a strong demand for various underwater electromechanical equipment. In the fields of hanging sonar systems, hanging underwater camera systems, etc., tensile joints have become commonly used connecting devices, such as the publication number CN2849326Y The patent discloses a tension-resistant joint, which is used to connect the ends of cables, steel wire ropes or fiber ropes. The shape of the tapered core is adapted to the inner cavity of the tapered sleeve. Although the transmission of the photoelectric signal is guaranteed, it is subject to constant waves. When working, the load-bearing cable will shake, and there is no special waterproof design, it...

[0002] At present, with the promotion and implementation of the national marine strategy, there is a strong demand for various underwater electromechanical equipment. In the fields of hanging sonar systems, hanging underwater camera systems, etc., tensile joints have become commonly used connecting devices, such as the publication number CN2849326Y The patent discloses a tension-resistant joint, which is used to connect the ends of cables, steel wire ropes or fiber ropes. The shape of the tapered core is adapted to the inner cavity of the tapered sleeve. Although the transmission of the photoelectric signal is guaranteed, it is subject to constant waves. When working, the load-bearing cable will shake, and there is no special waterproof design, it is very likely to malfunction and affect signal transmission, and the patent with the publication number of CN104183972A discloses a tensile connection structure of the cable and the use of the tensile connection The connector of the structure also uses the integral taper sleeve connection method to connect and fix the cables. Its main feature is to improve the installation efficiency of the cable tensile connection, but it will also greatly reduce the connection when used in a watertight environment. reliability
