[0002] MPP cable protection pipe, also known as modified polypropylene (MPP) power cable protection pipe, is a high-performance pipe made with MPP material as its core. It has excellent electrical insulation properties, which can effectively block current, prevent leakage or short circuit, and ensure the stable operation of the power system. At the same time, it has outstanding high temperature resistance and can work for a long time in environments ranging from -5℃ to 70℃. It also has a high heat distortion temperature and can withstand the heat generated by the cable.

[0003] For example, the utility model patent disclosed in publication number CN205920782U, MPP cable protection tube, includes a transparent film layer; the transparent film layer is circular in shape; a color-changing layer is wrapped inside the transparent film layer; a protective layer a is connected inside the color-changing layer; a temperature-sensing resistance wire is provided inside the protective layer a; a protective layer b is wrapped inside the protective layer a; the material of the protective layer a is modified polypropylene; the material of the protective layer b is modified polypropylene; one end of the temperature-sensing resistance wire is connected to the connector b circuit; the other end of the temperature-sensing resistance wire is connected to a wire; the temperature-sensing resistance wire is connected to a buzzer circuit through the wire; the other end of the buzzer is connected to an alarm light circuit through the wire; this utility model can change color at high temperatures to alert personnel, and the temperature-sensing resistance wire can sense the internal temperature of the protection tube and react accordingly.

[0004] Although the aforementioned cable protection pipe can monitor the internal temperature of the pipe, it is not convenient to quickly and easily connect multiple sets of cable protection pipes, thus reducing the practical performance of the pipe in subsequent use. Therefore, there is an urgent need for an MPP cable protection pipe with snap-fit ​​connectors to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an MPP cable protection pipe with snap-fit ​​connectors to solve the problems mentioned in the background art.

The positioning guide seat has a guide hole inside, which is slidably connected to the insertion shaft, so as to provide sufficient guiding foundation for the subsequent vertical displacement of the insertion shaft inside the positioning guide seat.

[0012] Preferably, the positioning plate is adapted to the positioning hole via the plug-in shaft and then fixedly plugged into the plug-in plate. When the plug-in plate is pushed to the inner limit of the positioning slot, the plug-in shaft can be plugged into the positioning hole, which can improve the stability of the docking limit of the two sets of protective tube shells.

[0024] The insertion device 3 is slidably engaged with the inner end face of the protective tube housing 6 via the positioning groove 4. The insertion device 3 is used for the docking and positioning of the two sets of protective tube housings 6.

[0025] The limiting device 2 includes a positioning plate 22, a handle 21 is provided at the top center of the positioning plate 22, and a plug shaft 23 is fixedly provided at the center of the lower end face of the positioning plate 22. A support spring 24 is provided on the outside of the lower end face of the positioning plate 22.

[0026] The insertion device 3 includes a guide slip ring 33. Six sets of insertion plates 32 are equidistantly arranged on the lower end face of the guide slip ring 33. A positioning chamfer 31 is provided at the bottom of the insertion plate 32. A positioning hole 34 is provided on the outer end face of the insertion plate 32 near the positioning chamfer 31.

[0027] The support spring 24 is fixedly connected to the inside of the positioning guide seat 7, and the insertion shaft 23 passes through the outer wall of the protective tube housing 6 to the inside of the positioning slot 8. The positioning guide seat 7 has a guide hole inside, which is slidably connected to the insertion shaft 23, so as to provide sufficient guiding foundation for the subsequent vertical displacement of the insertion shaft 23 inside the positioning guide seat 7.

[0028] The positioning plate 22 is adapted to the positioning hole 34 through the insertion shaft 23 and then fixedly inserted into the insertion plate 32. When the insertion plate 32 is pushed to the inner limit of the positioning slot 8, the insertion shaft 23 can be inserted into the positioning hole 34, which can improve the stability of the docking limit of the two sets of protective tube shells 6.

[0029] The guide slip ring 33 is adapted to the positioning slot 8 through the plug-in plate 32 and is slidably engaged inside the protective tube housing 6.

[0030] Working principle: When connecting multiple sets of protective tube housings 6 end to end, the user can align the two sets of protective tube housings 6 end to end, and then hold the guide slip ring 33 so that the six sets of plug-in plates 32 are aligned with the opening of the positioning slot 8. After positioning, the user can push the guide slip ring 33 towards the positioning slot 8. At this time, the guide slip ring 33 can drive the six sets of plug-in plates 32 to be inserted into the interior of the positioning slot 8, and then move along the inner wall of the positioning slot 8. The plug-in plates 32 can limit the bottom of the plug-in shaft 23 through the positioning chamfer 31, so that the plug-in plates 32 can push up the plug-in shaft 23 when moving. The plug-in shaft 23 moves upward under the elastic guidance of the support spring 24. When the plug-in plates 32 move to the limit inside the positioning slot 8, the plug-in shaft 23 can be inserted into the positioning hole 34 under the elastic guidance of the support spring 24, thus completing the locking operation.
