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

Embodiment 1

[0034] The penetrating shell 1 is made of stainless steel, with a total length of 45mm. There are M30 external threads on the right cylindrical wall, and the thickness of the partition structure is 3mm. It is located 6mm to the right of the middle, and there are 3 evenly distributed on it. The through hole is used for the passage and positioning of the cable 5; the left side of the partition structure is a tapered hole with a taper of 1:10, and the right side of the partition structure is a straight hole; the cable transfer device 3 is Copper column, length 15mm, with diameters at both ends A blind hole with a depth of 5mm; the cable 5 is welded with the transfer copper core by brazing; when potting, first insert the 3 cable transfer devices 3 into the 3 through holes of the bulkhead structure of the penetrating shell 1 , the blind holes at both ends of the cable transfer device 3 are respectively welded and fixed to the cables 5 on both sides of the bulkhead 7, and then th...

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...
