Description

Technical Field

[0001] This utility model relates to the field of cable protection pipes, and in particular to a connecting component for cable protection pipes. Background Technology

[0002] Cable protection pipes are metal protective pipes with a certain mechanical strength that are laid on the outer layer of cables to prevent damage. They are mainly installed at the intersection of communication cables and power lines to prevent short circuits caused by power line breaks, which could lead to energization of communication cables and steel wire ropes. This protects cables, switches, circuit boards, and even the entire device from being burned out. They also provide some isolation against magnetic field interference from power lines.

[0003] The prior art patent application with publication number CN222721052U describes a connection component that avoids high-temperature damage. During the connection process, welding is not required, preventing damage to the cable protection pipe from high temperatures and thus extending the pipe's service life. The connecting sleeve has an external sealing part with a sealing ring inside, which fits tightly against the outer wall of the cable pipe, effectively preventing damage to the cable from water, gas, and chemical corrosion. Compared to flange connections, this eliminates the need for reprocessing the cable protection pipe to install a flange, and the connection component is also more convenient for disassembly and installation.

[0004] However, currently, the cable conduit and sleeve are sealed and fixed together with sealant, and then fixed with bolts after the sleeve is placed inside the connecting sleeve. This makes it inconvenient to connect, install, and disassemble the cable conduits. Furthermore, when multiple sets of cable conduits are buried in a trench, it is inconvenient to connect the cable conduits to each other.

[0005] Therefore, it is necessary to provide a connection assembly for cable protection pipes to solve the above-mentioned technical problems. Utility Model Content
