Embodiment 1
[0032] please see Figure 1 to Figure 5 , a spring cable, comprising a center beam tube 3 located in the center and hollow inside, a plurality of optical fibers 4 located in the inner hollow part of the center beam tube; it is characterized in that the center beam tube has a spring armor layer 2 outside, and the spring The armor layer is close to the outer wall of the central beam tube, and the spring wires of adjacent layers in the spring armor layer are close to each other; the spring armor layer is extruded with a sheath layer 1 .
[0033] The spring cable described above is characterized in that the central bundle tube is made of polybutylene terephthalate
[0034] The above-mentioned spring cable is characterized in that the optical fiber is a single-mode fiber or a multi-mode fiber.
[0035] Furthermore, the spring cable mentioned above is characterized in that the optical fiber is G652 type or G655 type or G657 type or A1a type or A1b type.
[0036] The above-ment...
Embodiment 2
[0042] please see Figure 6 and Figure 8 , and combined with Figure 1 to Figure 5, a device for forming a spring armor layer on a spring cable, is characterized in that: it includes a bundle tube pan 51 wound with a central beam tube 3, a steel wire pan 52 wound with a spring wire 21, a spring The armor layer forms the mold 53; the bundle tube pan is rotatably fixed on the first fixed frame 511 through the first shaft 513, and the steel wire pan is rotatably fixed on the second fixed frame 521 through the second shaft 523; the first The fixing frame is fixed on the foundation, and the second fixing frame is fixed on the foundation. The first fixing frame and the second fixing frame are parallel; On the upper edge of the bundle tube tray; the spring armor layer forming mold is located in front of the bundle tube tray. In this device, the central bundle tube is released from the bundle tube tray and passes through the spring armor layer to form the center hole of the mold, ...
Embodiment 3
[0045] please see Figure 7 and Figure 9 , and combined with Figure 1 to Figure 5 , a device for forming a spring armor layer on a spring cable, is characterized in that: it includes a bundle tube pan 51 wound with a central beam tube 3, a steel wire pan 52 wound with a spring wire 21, a spring The armored layer forms the mold 53; the beam tube pan is rotatably fixed on the first fixed frame 511 through a shaft, and the steel wire pan is fixed on the twisted cage 522 and can rotate around the fixed shaft to release the spring wire; the first fixed frame is fixed On the foundation, the cage is rotatable around the axis 31 of the central tube; the spring armor forming mold is located in front of the tube pan. In this device, the central bundle tube is released from the bundle tube tray and passes through the spring armor layer to form the center hole of the mold, and is pulled forward; at the same time, the spring wire is released from the steel wire tray and enters the spri...
