[0027] like Figure 1 As shown, this utility model embodiment provides a flexible composite cable, including signal line units, power line units, a second wrapping layer 310, and an outer sheath 320. The signal line unit includes a signal conductor 110, a first insulation layer 120, a first wrapping layer 130, and a braided layer. The first insulation layer 120 is sleeved on the signal conductor 110 to form a signal core. The first wrapping layer 130 is wrapped around the signal core. The braided layer is disposed on the outside of the first wrapping layer 130. The first insulation layer 120 is made of fluoroplastic material. A plurality of power line units are evenly disposed around the periphery of the signal line units. The power line unit includes a power conductor 210 and a second insulation layer 220. The second insulation layer 220 is sleeved on the power conductor 210 to form a power core. The second wrapping layer 310 is wrapped around the outside of the signal line units and the power line units. The outer sheath 320 is sleeved on the outside of the second wrapping layer 310.
[0028] That is, the flexible composite cable provided in this embodiment of the utility model protects the signal line unit by placing the signal line unit inside the power line unit, and supports the first insulation layer 120 of the signal line conductor 110 with fluoroplastic material to ensure that the signal line core has good bending resistance. This solves the technical problems in the prior art where multiple signal lines are wrapped around the outside of the power line in communication composite cables, which lack protection for the signal lines, and the insulation layer is made of elastic materials such as silicone rubber, which has poor bending resistance.
[0029] Specifically, the signal conductor 110 provided in this embodiment of the invention is made of tin-plated copper wire stranded together, and the first insulation layer 120 is made of fluororubber. The first insulation layer 120 is extruded and wrapped around the outside of the signal conductor 110 to form the signal core, with a characteristic impedance of 100 ohms, which can meet the requirement of 100Mbps transmission speed. The first wrapping layer 130 is made of PTFE (polytetrafluoroethylene) material. PTFE is a high-performance synthetic fluoropolymer with excellent temperature resistance and insulation. The first wrapping layer 130 is wrapped around the outside of the signal core in a strip shape. A first braided layer 140 is also provided on the outside of the first wrapping layer 130. The first braided layer 140 is specifically made of galvanized copper wire braided with a braid density greater than 85%, which combines conductivity, corrosion resistance and mechanical strength, and can protect the internal signal core. The power line unit is made of a power line conductor 210 and a second insulation layer 220. The second insulation layer 220 is made of ETFE (Ethylene-Tetrafluoroethylene Copolymer), a high-performance fluoroplastic. The second insulation layer 220 is extruded and coated onto the power line conductor 210 to form the power core. The second wrapping layer 310 is made of PTFE (Polytetrafluoroethylene) and is wrapped around the outside of the signal line unit and the power line unit in a strip shape, thereby forming a cable core with an approximately circular cross-section. Suitable filler material can be filled into the signal line unit and the power line unit to ensure the roundness of the cable core. The outer sheath 320 is fitted over the outside of the second wrapping layer 310. The outer sheath 320 is specifically made of TPU (Thermoplastic Polyurethane) material extruded and coated with a thickness of 0.85mm, serving as a wear-resistant material to protect the internal cable core.
[0030] Preferably, a plurality of signal wire cores are twisted together within the first wrapping layer 130.
[0031] Specifically, in this embodiment, four signal cores are provided and twisted together within the first wrapping layer 130. By twisting together multiple signal cores, the signal transmission of the flexible composite cable is ensured to be stable.
[0032] Furthermore, the signal line unit also includes an inner sheath 150, which is sleeved on the outside of the first braided layer 140 and is made of polyvinyl chloride material.
[0033] Specifically, the inner sheath 150 is specifically configured to be extruded from PVC (polyvinyl chloride) material and covered on the outside of the first braided layer 140. By setting the inner sheath 150, the overall mechanical strength of the signal line unit can be further improved.
[0034] Furthermore, the flexible composite cable also includes a second braided layer 330 and a third wrapping layer 340; the second braided layer 330 and the third wrapping layer 340 are sequentially disposed between the second wrapping layer 310 and the outer sheath 320, the second braided layer 330 is sleeved on the outside of the second wrapping layer 310, and the third wrapping layer 340 is wrapped around the outside of the second braided layer 330; the second braided layer 330 is made of tin-plated copper wire braid, and the third wrapping layer 340 is made of non-woven fabric material.
[0035] Specifically, the second braided layer 330 is made of galvanized copper wire with a braiding density greater than 85%, possessing conductivity, corrosion resistance, and mechanical strength, and is wrapped around the outside of the inner sheath 150. The third wrapping layer 340 is made of non-woven fabric and is wrapped around the outside of the second braided layer 330 in a strip shape. By setting the second braided layer 330 and the third wrapping layer 340 made of non-woven fabric between the inner sheath 150 and the outer sheath 320, the flexibility and bending resistance of the flexible composite cable are further guaranteed.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
