Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a water-blocking and moisture-proof cable. Background Art

[0002] After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints. The cable joints are used to lock and fix the incoming and outgoing lines, and play a role in waterproofing, dustproofing and vibration proofing. Its main function is to make the line unobstructed, keep the cable sealed, and ensure the insulation level at the cable joints, so that it can operate safely and reliably. If the seal is poor, not only will oil leakage cause the oil-impregnated paper to dry out, but moisture will also invade the interior of the cable, causing its insulation performance to deteriorate.

[0003] In the prior art, a Chinese invention patent document with publication number CN movable sleeve (11) 2582968B has been proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a composite moisture-proof cable with a simple and practical structure, which can ensure reliable connection of the cable joint part and its tensile strength, comprises a first cable, a second cable and a connecting device for connecting the first cable and the second cable, the connecting device comprises an intermediate sheath, a left connecting sleeve, a right connecting sleeve and a rubber sealing ring, and a cylindrical cavity is provided in the middle of the intermediate sheath.

[0004] In the above solution, since the middle sheath is integrally formed, the installer cannot observe the real-time status of the cable during the process of inserting the cable into the middle sheath, and is unclear whether the cable is properly docked. This may easily lead to the two cables not being properly docked and unable to be powered. For this reason, we propose a water-blocking and moisture-proof cable to solve the above problem.
