Spiral groove type electrical cable penetration assembly and manufacturing method thereof

Abstract

The invention discloses a spiral groove type electrical cable penetration assembly and a manufacturing method thereof, and relates to the field of electrical cable penetration assembly structures, the spiral groove type electrical cable penetration assembly comprises a pressure-bearing connecting shell, and the two ends of the pressure-bearing connecting shell are a high-voltage end and a low-voltage end respectively; a penetrating through hole is formed in the pressure-bearing connecting shell and penetrates through the high-pressure end and the low-pressure end, and a limiting part is arranged at the position, close to the low-pressure end, in the penetrating through hole; a core body is arranged in the penetrating through hole, at least one spiral groove is formed in the periphery of the core body, an electrical cable is arranged in each spiral groove, and all the spiral grooves are filled with an adhesive; adhesive is filled between the outer wall of the core body and the inner wall of the through hole; one end of the core body is connected with the limiting part through the bottom supporting plug, and the high-pressure end is connected with a pressing mechanism which acts on the other end of the core body; the two ends of the electrical cable penetrate through the bottom supporting plug and the pressing mechanism respectively. According to the invention, a good sealing effect can be achieved in a high-pressure-difference environment.
