Description

Technical Field

[0001] This utility model relates to the field of cables, and more specifically, to a photoelectric composite reel flat cable. Background Technology

[0002] Reel cables are widely used in the connection and control of reel machines, conveyors and conveying machinery. They are also used as drums and drag cables in drag chain systems, moving in and out of the machine with the guidance of the drag shaft or other similar devices.

[0003] In abrasion-prone environments, cables often need to withstand friction, compression, and tension from various directions. While existing reel cables and round cables are widely used, their edges and corners are prone to wear in such environments, thus affecting the overall performance and lifespan of the cable. Furthermore, in applications requiring frequent movement and bending, such as automated production lines, robotic arms, conveyor machinery, and cable chain systems, traditional reel cables are often easily damaged due to their high material rigidity and insufficient flexibility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photoelectric composite reel flat cable, comprising a wear-resistant outer sheath and a filling layer located within the wear-resistant outer sheath. The wear-resistant outer sheath is made of nitrile rubber. The filling layer has a flat cross-section. The filling layer contains a row of optical cable units, a ground wire, multiple power lines, and multiple tensile members. Each optical cable unit includes an inner sheath, within which multiple optical cable cores and multiple filling ropes are arranged. Each optical cable core includes a protective sleeve and an optical fiber located within the protective sleeve. Each power line includes a first conductor, a first elastomer insulation, and a reinforcing layer arranged sequentially from the inside out. The ground wire includes a second conductor and a second elastomer insulation covering the second conductor. Both the first and second elastomer insulations are made of chloroprene rubber or chlorosulfonated polyethylene. The tensile members include a braided layer and a tensile layer located within the braided layer. The braided layer is made of aromatic polyamide fiber, and the tensile layer is made of galvanized steel wire.

[0006] Furthermore, the power lines are three in number, namely a first power line, a second power line, and a third power line, the optical cable unit is located between the first power line and the second power line, and the ground wire is located between the second power line and the third power line.

[0007] This enhances the overall structural stability and safety of the cable.

[0008] Furthermore, the tensile member has two parts, which are located at both ends of the filler layer.

[0009] This improves the tensile strength of the cable.

[0010] Furthermore, the protective sleeve is filled with a filling grease.

[0011] This provides additional buffering and protection for the optical fiber core.

[0012] Furthermore, the number of optical fiber cores and filler ropes are the same, and the multiple optical fiber cores are arranged in a ring, with one filler rope between two adjacent optical fiber cores and the inner sheath.

[0013] This further improves the tensile strength of the cable.

[0014] Furthermore, the reinforcing layer is made of galvanized steel strip.

[0015] This improves the mechanical properties of the cable.
