Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-4 As shown, the utility model provides the following technical solutions: an insulated waterproof optoelectronic composite cable, comprising an outer sheath 1, a filling layer 7 is installed on the inner side of the outer sheath 1, the outer sheath 1 is the outermost protective layer of the cable, protecting the internal structure of the cable, the conductor sheath 5 is evenly distributed in the filling layer 7, and the filling layer 7 is provided with evenly distributed embedding grooves 8, which can provide installation space for the optoelectronic element 6, the optoelectronic element 6 is sleeved in the embedding groove 8, and the embedding groove 8 can make the optoelectronic element 6 stably embedded therein without being mechanically damaged.

[0025] On the basis of the above embodiment, a steel belt armor layer 2, an inner sheath 3 and a wrapping tape 4 are arranged between the outer sheath 1 and the filling layer 7. The steel belt armor layer 2 is embedded in the inner wall of the outer sheath 1. The outer sheath 1 and the inner sheath 3 can cover and protect all structures on the inner side of the inner sheath 3. In this embodiment, the outer sheath 1 and the inner sheath 3 are both made of polypropylene material, which has good wear resistance and corrosion resistance. Of course, the outer sheath 1 and the inner sheath 3 can also be made of other materials, and the utility model is not specifically limited here. The wrapping tape 4 is coated on the outside of the filling layer 7, and the inner sheath 3 is located between the steel belt armor layer 2 and the wrapping tape 4. The steel belt armor layer 2 can effectively improve the overall strength of the cable and can cope with stronger external impacts. The wrapping tape 4 is made of polyester fiber material, which has high durability, good waterproofness, and better strength and stability. The conductor sheath 5 is sleeved with an aluminum core conductor 15 and an anti-water tree insulation layer 13. The conductor sheath 5 provides protection for the outermost layer of the aluminum core conductor 15. In this embodiment, the conductor sheath 5 is made of polyethylene material, which has good electrical properties and high-frequency insulation, and is not affected by humidity. Of course, the conductor sheath 5 can also be made of other materials, and the utility model is not specifically limited here. The aluminum core conductor 15 is the main working part of the entire cable for transmitting electric energy. It should be noted that the aluminum core conductor 15 adopts a pressed circular design, which not only improves the voltage resistance of the cable, but also reduces the weight and space occupied by the cable. A longitudinally overlapped aluminum-plastic composite tape 9 is also installed in the conductor sheath 5. The longitudinally overlapped aluminum-plastic composite tape 9 is sleeved in the conductor sheath 5 to form a metal waterproof layer, which not only ensures the use effect of the metal waterproof layer, but also reduces the unit length weight of the optoelectronic composite cable.
