Description

Technical Field

[0001] The utility model relates to the technical field of cable protection tubes, in particular to a power cable protection tube connection assembly. Background Art

[0002] MPP power cable protection pipe uses modified polypropylene as the main raw material. It is suitable for laying pipelines and cables in special areas such as roads, railways, buildings, and riverbeds without the need for large-scale dredging, excavation, or damage to the road surface.

[0003] In the prior art, a Chinese patent with publication number "CN220475346U" discloses a power cable protection tube connection assembly. The control panel and control buttons set on the mounting ring can control the start of the lifting cylinder through the sensing layer, thereby increasing the stability of the product during connection. The protective layer set by the mounting ring can protect the cable when placed inside the cable protection tube, thereby solving the problem that the existing connecting sleeve is not convenient for fixing the product inside the equipment, causing the product to slip out of the equipment.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] When using current power cables, since they need to be laid underground, in order to extend the life of the cables and slow down the aging of the insulation sheath, it is often necessary to isolate the cables from the external environment. Most of the time, protective tubes are used to seal the cables. Since the power cables are installed on the protective tubes for convenience, the protective tubes are usually not set too long. However, when the protective tubes are installed on the power cables in turn, there are no connecting components between the two protective tubes, resulting in connection gaps between adjacent protective tubes. The power cables underground are easily eroded by soil and moisture, which can easily cause damage to the power cables. Utility Model Content
