In the prior art, CN210956243U discloses a heat dissipation cable, including a cable outer layer and a battery core. A waterproof layer is provided inside the cable outer layer, and the waterproof layer is in close contact with the inner wall of the cable outer layer. A plurality of extensions are provided on the waterproof layer, and a battery cell arrangement channel is provided in the extension. Battery cells are arranged in the battery cell arrangement channel. A groove is provided on the side of the extension facing the cable outer layer, and a plurality of air inlet holes connected to the groove are provided on the cable outer layer, and the other end of the air inlet hole is connected to the external environment; two adjacent extensions are connected by a breathable component, and a plurality of air outlet holes connected to the battery core are provided on the extension, and the breathable component isolates the air outlet holes; the surface of the cable outer layer is wrapped with a waterproof film, and a plurality of breathable micropores are provided on the cable outer layer, and the waterproof film covers the breathable micropores.

[0003] The above-mentioned prior art has the following drawbacks: 1. The structure is complex, and various air outlet holes, air permeability micropores, air inlet holes, etc. need to be formed on the components inside the cable, which is inconvenient to process; 2. The battery cell is fixed in position and the anti-seismic effect is poor. Summary of the invention

[0004] To solve the above problems, the purpose of the present invention is to disclose an optoelectronic hybrid cable, which is implemented by adopting the following technical solutions.

[0005] A photoelectric hybrid cable comprises an outer sheath, four optical units and four electrical units, wherein the optical unit is composed of a loose tube and at least one optical communication component located in the loose tube, and the electrical unit is composed of a conductor and an insulating layer extruded outside the conductor. The invention is characterized in that the outer sheath is composed of eight arc-shaped outer sheath bodies, and four concave points a and four convex points b are formed, four isolation protection components are formed along the same direction on the inner side of the outer sheath at the four concave points a, one end of each isolation protection component is bent to form an open optical unit cavity, a central cavity is formed between the four optical unit cavities, the outer sheath body corresponding to each convex point b and the corresponding isolation protection component form an electrical unit cavity and a release port, the optical unit is located in the optical unit cavity, the outer diameter of the optical unit is larger than the opening of the optical unit cavity, and the electrical unit is located in the electrical unit cavity, the outer diameter of the electrical unit is smaller than the release port.

[0007] The above-mentioned optoelectronic hybrid cable is characterized in that the concave point a is located on the inner side of the line connecting two adjacent convex points b.

[0008] In the above-mentioned optoelectronic hybrid cable, since the electrical unit cavity is connected to the central cavity through the detachment port, the heat generated by the electrical unit during operation can be discharged through the central cavity, and the curvature radius of the outer sheath body corresponding to the electrical unit is different from the curvature radius of the electrical unit, so that the contact surface between the outer sheath body and the electrical unit is small, further improving the heat dissipation efficiency of the optoelectronic hybrid cable; the material between the optical unit and the electrical unit is a heat-insulating material, so that the heat on the surface of the electrical unit will not be directly transmitted to the optical unit, thereby protecting the normal operation of the optical unit; only one end of the isolation protection component is fixed to the outer sheath body, so that the other end of the isolation protection component can move in the central cavity, and when the optoelectronic hybrid cable is subjected to impact force, the electrical unit and the optical unit can offset most of the impact force through the movement of the isolation protection component, thereby preventing the internal optical fiber from being subjected to a large impact and breaking; the optoelectronic hybrid cable of this embodiment has a non-circular shape, and the concave point a is located on the inner side of the line connecting the corresponding two adjacent convex points b, which can prevent the optoelectronic hybrid cable from twisting during laying.

[0009] The above-mentioned optoelectronic hybrid cable is characterized in that the optical communication component is an optical fiber or an optical fiber ribbon formed by at least two optical fibers.

[0010] The above-mentioned optoelectronic hybrid cable is characterized in that the optical fiber is G.652 optical fiber, G.653 optical fiber, G.654 optical fiber, G.655 optical fiber, G.656 optical fiber, G.657 optical fiber, A1a optical fiber, A1b optical fiber or A1c optical fiber.

An isolation protection component cavity is formed between two adjacent blades, and an open groove is formed on the isolation protection component cavity. Each blade has a first arc edge and a second arc edge. Each blade is embedded in the corresponding release port, the first arc edge abuts against the electrical unit, and the second arc edge abuts against the outer sheath body. One end of the isolation protection component penetrates into the isolation protection component cavity, and the distance of the open groove is greater than the bending radius of one end of the isolation protection component.

[0012] The above-mentioned optoelectronic hybrid cable is characterized in that the reinforcement member is made of stainless steel or glass fiber reinforced plastic rod.

[0013] The above-mentioned optoelectronic hybrid cable has an additional reinforcement member, which improves the tensile strength of the optoelectronic hybrid cable. At the same time, the special shape of the reinforcement member can further fix the electrical unit and the optical unit, prevent the displacement of the electrical unit and the optical unit, and improve the compressive strength of the optoelectronic hybrid cable.

[0014] The above-mentioned optoelectronic hybrid cable is characterized in that the outer sheath material is low-density polyethylene, medium-density polyethylene, high-density polyethylene, flame-retardant polyolefin, polyvinyl chloride, nylon or polytetrafluoroethylene.

[0015] The above-mentioned optoelectronic hybrid cable is characterized in that the insulating layer material is low-density polyethylene, medium-density polyethylene, high-density polyethylene, flame-retardant polyolefin or polyvinyl chloride.

[0016] The above-mentioned optoelectronic hybrid cable is characterized in that the conductor is copper wire, aluminum wire or enameled copper wire.

[0017] The above-mentioned optoelectronic hybrid cable is characterized in that the loose tube material is polybutylene terephthalate or modified polypropylene.

[0018] In the present invention, when the size of the central cavity is larger than the outer diameter of the electrical unit and the optical unit, the electrical unit and the optical unit can be embedded from the central cavity into the electrical unit cavity and the optical unit cavity at a later stage. During construction, it is convenient to replace the electrical unit and the optical unit without re-laying a new optoelectronic hybrid cable, thus saving construction time, improving construction efficiency, and saving resources. The outer sheath of the present invention can be formed in one piece, with a simple structure, convenient processing, and high production efficiency.

[0019] Therefore, the present invention has the beneficial effects of simple structure, good heat dissipation performance, convenient construction, high efficiency, resource saving, pressure resistance, impact resistance, and torsion resistance. BRIEF DESCRIPTION OF THE DRAWINGS
