Underwater acoustic array output cable and sealed connection method thereof

Abstract

The invention relates to an underwater acoustic array output cable comprising multi-stage cable unit. Each two adjacent stages of cable units are connected mutually by a sealed connection structure. The sealed connection structure consists of an adapter and a switch sleeve. Wire tapping units of the cable unit at the previous stage and the cable unit at the later stage are connected to and installed at the adapter and are in contact at the adapter to form electrical connection. Each switch sleeve being vulcanized rubber sleeve is arranged at the periphery of the cable unit at the previous stage, the cable unit at the later stage, and the adapter and covers the exposed wire tapping unit of the cable unit at the previous stage, the exposed wire tapping unit of the cable unit at the later stage, and the adapter completely. According to the invention, each vulcanized rubber sleeve coats the connection part between each two adjacent stages of cable units to realize comprehensive sealing of the connection part between the cable unit at the previous stage and the cable unit at the later stage. The structure of the cable is simple; and the insulating property of underwater sealing of the underwater acoustic array output cable is enhanced.

Description

technical field [0001] The invention belongs to the technical field of sonar, and in particular relates to the structure of an underwater acoustic array. Background technique [0002] With the development of the situation of research, development and utilization of marine resources, various types of sonar emerge in endlessly. The acoustic array (transducer), which is the main part of the wet end of the sonar, must work in water. Because the acoustic matrix is ​​installed on a certain matrix frame by several transducers (several to several thousand) according to certain rules. When receiving (sending) in phase space, all transducers participating in the array must input (output) signals separately, because the input (output) signal of each transducer contains extremely important phase information, so that the underwater acoustic The number of output cable cores of the array will correspond to the number of transducer units in the acoustic array, and there will be many outpu...

AI Technical Summary

Problems solved by technology

The assembly of the seal ring is done manually, and the difference between individuals will cause the assembly quality to be different. Although many hydraulic tests will be carried out afterwards, most (more than 90%) of the insulation drop in actual operation is caused by improper assembly. Yes, that is, the human factors in the assembly of the sealing ring will cause poor sealing reliability, which will greatly affect the reliability of the underwater acoustic matrix

At the same time, the use of the junction box makes the volume occupied by the underwater acoustic array output cable too large, and the reliability of the assembly and sealing structure of the sealing ring is poor, which greatly affects the use of the underwater acoustic array output cable
