Examples
A lightweight ribbon cable as shown in fig. 1, comprising in particular:
the wire sheath 100, a plurality of wire cavities 101 for arranging wire bodies 2011 and a core wire 200 arranged in the wire cavities 101;
the wire cavity 101 is in a U-like shape, the U-shaped opening end faces the axis of the cable, the end heads 1011 at the two ends of the U-shape are in a water drop shape with increased cavity diameters, the core wire 200 is filled in the end head 1011 part of the wire cavity 101, and the core wire 200 is limited in the end head 1011 of the wire cavity 101 due to the unique structural characteristics of the end head 1011;
the core wire 200 is formed by wrapping a plurality of optical fiber wires 201 with a bundle tube 202, wherein the optical fiber wires 201 comprise a wire body 2011 and an optical fiber belt 2012 embedded and fixed in the wire body 2011 along the axial direction of the belt cable;
the wire cavities 101 are uniformly arranged around the axial center of the belt cable on the radial section of the belt cable, the number of the wire cavities is not more than four, and as in the embodiment, three wire cavities 101 are arranged in total;
the center of the sheath 100 is provided with a central cavity 102, and the central cavity 102 is petal-shaped so as to realize compression resistance and buffering when the sheath 100 is stressed and shrink when the sheath 100 is twisted;
a hollow buffer tube 300 is disposed within the central lumen 102.
Under the cooperation of the structure, the ribbon cable has good compression resistance and torsion resistance, and due to the structural characteristics, the ribbon cable has the potential of realizing a super-multi-core ribbon cable, and is different from a conventional layer-twisted ribbon cable, and a plurality of core wires 200 with large wire diameters are allowed to be accommodated so as to increase the number of optical fiber wires 201;
as shown in fig. 2, when the belt cable is pressed, if the upper end of the belt cable is stressed, the U-shaped closed end of the upper side line cavity 101 is compressed, the inner side wall and the outer side wall of the closed end are closed, the displacement of the upper side line cavity 101 drives the core wire 200 arranged in the upper side line cavity 101 to generate downward acting force, and the two core wires 200 arranged in the lower side left and right line cavities 101 and close to the upper side line cavity 101 are subjected to force to generate displacement along the line cavity 101, the displacement can reduce the direct stress of the core wire 200 and convert the single-point stress into the area stress, namely the single-point stress is subjected to the extrusion action of the wall of the line cavity 101, and the extrusion of the wall of the line cavity 101 reversely limits the displacement of the single-point stress, so that the displacement distance of the single-point stress is reduced after the belt cable is stressed actually, the tearing action of the core wire 200 is avoided, and simultaneously the central cavity 102 and the hollow buffer tube 300 are pressed to form a deformation buffering effect in the process;
as shown in fig. 3, when the ribbon cable of the present invention is twisted, due to the special structure of the wire cavity 101, the actual deformation is the closed end of the wire cavity 101, the closed end is twisted along with the sheath 100, and at this time, the inward twisting shrinkage deformation of the sheath 100 can generate a relatively remarkable elastic restoring force to offset the external twisting force applied to the ribbon cable, so as to generate a good torsion resistance effect, and the deformation of the wire cavity 101 at this time does not directly drive the core wire 200 arranged at the end 1011 portion of the wire cavity to twist, but drives the core wire 200 to generate a smaller displacement towards or away from the axis of the ribbon cable, at this time, the core wire 200 actually also generates a limiting effect, so as to avoid excessive twisting deformation of the ribbon cable.
Further, the method comprises the steps of,
a reinforcement 400 is arranged on the inner side of the closed end of the wire cavity 101, and the reinforcement 400 is arranged on the outer side of the core wire 200 along the radial direction of the belt;
the reinforcement 400 can directly and effectively improve the compression resistance of the ribbon cable, because it can directly absorb and buffer the external force applied to the ribbon cable as a bearing component, and when the sheath 100 of the ribbon cable is partially twisted, it can also effectively limit the deformation of the inner wall of the closed end of the wire cavity 101, so that the torsion force is more difficult to further conduct inwards on the core wire 200, and the torsion resistance of the ribbon cable is enhanced;
the sheath 100 is also provided with a buffer cavity 103 corresponding to the wire cavity 101;
the buffer cavity 103 is elliptical in radial section of the belt cable, and the radial line of the belt cable passes through the short shaft of the buffer cavity 103;
the buffer cavities 103 and the wire cavities 101 are arranged in equal number and are uniformly and alternately arranged in the circumferential direction;
the arrangement of the buffer cavity 103 is not obvious for improving the compression resistance of the belt cable, but is obvious for improving the torsion resistance of the belt cable, mainly because the buffer cavity 103 can be matched with the reinforcing piece 400 to inhibit the torsion deformation of the closed end of the wire cavity 101 under the action of torsion acting force, due to the structural characteristics of the buffer cavity 103, the deformation of the outer wall of the closed end of the wire cavity 101 can drive the long shaft of the compression buffer cavity 103, the long shaft is compressed, the short shaft side length of the long shaft can generate larger elastic force to resist the torsion force, so that the deformation difficulty of the outer wall of the closed end of the wire cavity 101 is increased, the reinforcing piece 400 can inhibit the deformation of the inner wall of the closed end of the wire cavity 101, and the integral deformation difficulty of the closed end of the wire cavity 101 is increased under the comprehensive action to block the torsion force from being transmitted to the core wire 200 inwards continuously, and a good torsion protection effect is generated on the core wire 200.
