Description

Technical Field

[0001] This utility model relates to a flange for electrical components, specifically an insulating basin flange. Background Technology

[0002] The shielding cover, insulating basin, and matching flange in electrical equipment constitute a critical protection system. As a connecting component, the flange achieves rigid fixation and isolation of conductive paths between multiple components through a precision sealing design. Its metal material combines mechanical strength and corrosion resistance. In environments with strong electromagnetic interference, such as high-voltage switchgear and substations, the flange and shielding cover form a continuous grounding network, effectively suppressing arc radiation and high-frequency noise coupling. Combined with the composite dielectric material of the insulating basin, it can withstand tens of thousands of volts of impulse voltage and block leakage current paths, ensuring that the equipment can maintain stable insulation performance under harsh conditions such as humidity and salt spray, significantly improving the reliability of the power system and the safety of personnel operation.

[0003] In the prior art, 201821919945.3 discloses a flange assembly for reinforced concrete utility poles. This utility model discloses a flange assembly for reinforced concrete utility poles, including a first flange and a second flange. A steel ring is welded between the first and second flanges. The top of the first flange has annularly distributed locking holes, and the top of the second flange has a connecting hole. A bolt is threadedly connected to the inner wall of the locking hole. A rust-proof plate is provided at the bottom of the bolt, and a protective cap is provided in the middle of the rust-proof plate. A plug-in seat is fixedly connected to the top of the rust-proof plate. The bolt is plugged into the plug-in seat. A plug hole is provided on one side of the plug-in seat, and a threaded groove is provided at the lower end of one side of the bolt. A screw is threadedly connected to the inner wall of the plug hole. A protective cover is fitted onto the outer side of the first flange. This utility model solves the problem that flanges and the locking components used for connection are in long-term contact with the external environment, requiring frequent rust-proof cleaning of the outer surface of the flange.

[0004] The existing flange technology has the problem of poor sealing effect in the sealing cavity when partial connection is not possible. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an insulating basin flange.

[0006] This utility model is achieved using the following technical solution: an insulating basin flange, comprising a flange body, an inner flange ring and an outer flange ring, a transition component between the inner and outer flange rings, the transition component being a transition step located inside the outer flange ring, a central assembly through hole in the middle of the flange body, an internal sealing component inside the central assembly through hole, an external secondary assembly component outside the outer flange ring on the flange body, an insulating basin connecting sleeve on the flange body, an internal locking component on the insulating basin connecting sleeve, and a sealing inner groove within the sealing inner groove, wherein a filling gap is provided, and a flexible adhesive filling layer is provided within the filling gap.

[0007] The insulating basin connecting sleeve has a connecting space inside, and the inner wall of the connecting space has an assembly groove, and the assembly groove has an internal locking component.

[0008] The internal locking component is a locking slider, and a sliding space is provided in the assembly groove. The locking slider is distributed in the sliding space in the assembly groove, and a secondary locking groove is provided inside the assembly groove.

[0009] The locking secondary groove is located at the bottom of the assembly groove, and a locking hole is provided in the locking secondary groove. The locking hole passes through the locking secondary groove and the insulating basin connecting sleeve.

[0010] The locking slider is provided with an assembly position, and a threaded upright is assembled at the assembly position by means of a thread, and the threaded upright is provided with an external thread.

[0011] The threaded upright is fitted with a fastening nut by means of external threads. The insulating basin connecting sleeve is provided with traction components on both sides. The traction components are traction rods. The traction rods are provided with mounting bosses between the insulating basin connecting sleeves and the traction rods. The insulating basin connecting sleeves and the traction rods are further fixed by bolts on the mounting bosses.

[0012] Compared to existing technologies, this utility model's insulating basin flange adopts a double-ring layout, dividing the flange into an inner ring and an outer ring, with a transition step between them to enhance structural stability. The central through-hole contains a sealed inner groove and a flexible rubber filling layer, providing sealing compensation for the assembled components and effectively preventing media leakage and moisture intrusion, thus improving the sealing performance between the flange and the assembled components. For further assembly of the insulating basin flange, a sliding locking slider engages with a secondary groove, allowing the locking slider to slide into the secondary groove for further assembly and fixation. Further fixation is achieved using nuts on the threaded uprights, ensuring controllable locking positions. The two side traction rods are fixed to bolts on the assembly bosses, facilitating further side assembly of the insulating basin flange and enabling excellent side traction assembly.
