Title:
STEEL WIRE MESH REINFORCED COMPOSITE PIPE HIGH-VOLTAGE CONNECTOR, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/070869
Kind Code:
A1
Abstract:
A steel wire mesh reinforced composite pipe high-voltage connector, and a manufacturing method therefor. The steel wire mesh reinforced composite pipe high-voltage connector comprises a first connecting assembly disposed at an end portion of a first composite pipe, a second connecting assembly disposed at an end portion of a second composite pipe, and a lock ring fixedly connecting the first connecting assembly and the second connecting assembly; the first connecting assembly comprises a welding metal ring disposed on an exposed section of a steel wire layer of the first composite pipe, an end injection molding member wrapping the exposed section of the steel wire layer of the first composite pipe, and a first outer buckling sleeve disposed on an outer layer of the first composite pipe; the second connecting assembly comprises a welding metal ring disposed on an exposed section of a steel wire layer of the second composite pipe, an end injection molding member wrapping the exposed section of the steel wire layer of the second composite pipe, and a second outer buckling sleeve disposed on an outer layer of the second composite pipe. In the high-pressure connector, the welding metal rings are disposed and welded to a steel wire reinforcing layer, and meanwhile, end injection molding is performed on the positions where the welding metal rings are located. Compared with existing connection modes, the pressure bearing capacity of connection is greatly improved.
