A potted cable sealing penetration structure

Abstract

The invention relates to a potted cable sealing penetration structure, comprising a penetration shell, an adapter copper core and a potting material. The penetration shell is a cylinder, the two endsof the cylinder are provided with blind holes, and a partition plate structure is formed between the blind holes at the two ends; the penetration shell passes through the outer bulkhead and is sealedand fixed with the outer bulkhead; N through holes are arranged in the partition structure to penetrate the spaces on both sides of the outer bulkhead; n cable adapters are respectively inserted inton through holes of the penetration shell partition structure, The two ends of the cable adapter are fixedly connected with the cables at the two ends of the outer bulkhead respectively, the blind holes at the two ends of the cylinder of the penetration shell are filled with potting material, and the end face of the cable adapter is not higher than the end face of the penetration shell. The invention realizes the sealing penetration of the cable through the potted penetration structure.

Description

technical field [0001] The invention relates to an encapsulation-type cable seal penetrating structure, in particular to a cable sealing structure for realizing the penetrating of cables from the insulating oil side to the air side. Background technique [0002] In the design and application of underwater propulsion motors, the integrated design of control drives and propulsion motors has received more and more attention due to its advantages of small size, light weight, and low noise. [0003] In the integrated design process of the underwater propulsion motor, in order to balance the external pressure and at the same time ensure the effective heat dissipation of the motor and the effective lubrication of the bearings, it is usually necessary to fill the inside of the motor with oil; and a large number of electronic components are installed inside the control drive end , cannot be treated with oil filling. In this case, the power cable and control cable of the motor also n...

AI Technical Summary

Problems solved by technology

[0005] 1) The mechanical extrusion structure is complex and the structure size is large;

[0006] 2) The sealing wall structure can only seal the sheath of the cable through the cabin. If the sheath of the cable is damaged due to improper operation during use and is not found in time, when the water pressure is high, water can leak through the gap in the cable , leading to seal failure, reliability cannot be guaranteed
