Utility Model Content

[0003] In view of the above problems, the utility model provides an MLCP composite reinforced power communication protective casing which not only has impact resistance and flame retardant protection effect, but also has higher safety.

[0012] Another technical solution of the utility model is: an MLCP composite reinforced power communication protective casing, the protective casing is composed of two detachably connected tube bodies, the cross-section of the tube body is semi-annular, and its cross-section is mainly composed of an impact-resistant layer and a flame-retardant layer, the flame-retardant layer is sleeved inside the impact-resistant layer, and an annular hollow layer for heat dissipation is formed between the impact-resistant layer and the flame-retardant layer, and a longitudinally through-through routing space for power and telecommunication cable routing is opened inside the flame-retardant layer.

[0013] The protective sleeve is designed to be composed of two detachably connected tube bodies and can be produced in a split manner, thereby reducing the difficulty of manufacturing the protective sleeve.

At the same time, the hollow layer forms the second layer of heat dissipation channel, and the first layer of heat dissipation channel cooperates with the flame retardant layer and the second layer of heat dissipation channel, thereby improving the safety of the protective sleeve as a whole.

[0018] 2. The hollow layer is provided with a plurality of reinforcing ribs for supporting and reinforcing, thereby supporting and reinforcing the hollow layer.

[0019] 3. The support and reinforcement effect in the hollow layer is further optimized by designing that the reinforcing ribs extend in the longitudinal direction and are evenly distributed in the hollow layer in a rectangular array or a circular array.

[0020] 4. The reinforcing ribs are provided with a plurality of heat exchange holes for heat exchange between two adjacent heat dissipation spaces, thereby enhancing the fluidity between the heat dissipation spaces.

[0021] 5. The hemispherical design of the outer contour of the protrusion further reduces the friction of the power and telecommunication cables in the running space.

[0022] 6. The protective sleeve is designed to be composed of two detachably connected tube bodies and can be split for production, thereby reducing the manufacturing difficulty of the protective sleeve.

[0023] 7. Compared with the traditional solid wall type pipes, which are thick at both ends and thin in the middle, and can bear pressure at both ends but not in the middle, the pipe wall of the protective sleeve of the utility model is not solid wall type, and the thickness at any part is equal and has the same pressure bearing capacity.
