A ribbon cable as shown in fig. 1, comprising in particular:
the array beam tube 100, the oblong beam tube 200, the inner sheath 300 and the outer sheath 400 are sequentially arranged from inside to outside;
the array beam tube 100 is formed by a plurality of beam tube units 101 which are arranged along the length direction of the section of the ribbon-shaped optical cable, the beam tube units 101 are in spindle shape along the length direction of the section of the optical cable, are abutted with the inner surface of the oblong beam tube 200, the connecting line of two sharp end points of the beam tube units is perpendicular to the length direction of the section of the optical cable, spindle-shaped cavities 102 with the same or similar shape as the outer shape are arranged in the array beam tube, optical fiber wires 103 are arranged in the cavities, and the optical fiber wires 103 are abutted with the inner side walls of the middle parts of the cavities;
the middle parts of the outer side walls of the plurality of beam tube units 101 forming the array beam tube 100 are connected, and the beam tube units 101 at the outermost end are abutted with the middle parts of the inner side walls of the oblong beam tubes 200 to form hollow elastic tubes 201;
the array beam tube 100 and the oblong beam tube 200 are both made of elastic materials, and in this embodiment, the array beam tube 100 and the oblong beam tube 200 are both made of elastic silicone rubber.
Under the cooperation of the structure, the ribbon cable has a very excellent compression-resistant effect, because of the structural characteristics of the ribbon cable, the ribbon cable is most easily subjected to the acting force F1 from the short direction of the section of the ribbon cable as shown in fig. 2, the ribbon cable is generally flat and is internally filled tightly, the deformable and buffering space is small, the acting force is easily transmitted to the optical fiber 103 directly after being stressed, and the optical fiber 103 is directly stressed, so that the optical fiber 103 is easily damaged. However, the array beam tube 100 and the unique beam tube unit 101 thereof form a buffer deformation space, the spindle-shaped beam tube unit 101 deforms along the direction a after the optical cable is stressed until the inner tip of the optical cable contacts the optical fiber line 103, the optical fiber line 103 cannot receive direct acting force, if the array beam tube 100 with the structure is only arranged, the optical cable is easy to deform along the short direction of the section, namely the deformation force threshold which can actually cause the deformation of the optical cable is reduced, after the hollow elastic tube 201 is arranged, the array beam tube 100 and the hollow elastic tube 201 form tight connection along the length direction of the optical cable in the oblong beam tube 200, the deformation trend of the beam tube unit 101 can be changed, the deformation of the beam tube unit 101 along the direction b is blocked, the structure of the beam tube unit is limited, the actual deformation force threshold of the beam tube unit 101 is further improved, the effect of assisting the beam tube unit 101 in resetting can be also achieved, the compression resistance of the optical cable can be remarkably improved, meanwhile, the deformation force threshold of the optical cable along the short direction of the section is easy to reduce, and the external beam tube 100 is easy to restore after the external beam force is more obviously lost.
Further, the method comprises the steps of,
the inner sheath 300 and the outer sheath 400 are connected in a matched manner through a tooth-shaped structure;
as shown in fig. 1, tooth-like structures are provided at both ends of the cable in the short direction of the cross section, at the junction of the inner sheath 300 and the outer sheath 400;
specifically, the outer surface of the inner sheath 300 forms a trapezoid outer protrusion 301 towards the outer sheath 400 and is embedded into the outer sheath 400, and the inner surface of the outer sheath 400 is correspondingly provided with a trapezoid inner protrusion 401 and is embedded into the outer surface of the inner sheath 300, wherein the trapezoid outer protrusion 301 and the trapezoid inner protrusion 401 are alternately arranged;
a hexagonal cavity 302 is arranged in the trapezoid outer protrusion 301, the optical cable section is regular hexagon, and the side wall of the hexagonal cavity 302 facing outwards along the short direction of the optical cable section is parallel to the outer side wall of the trapezoid outer protrusion 301;
a trapezoid cavity 402 is arranged in the trapezoid inner protrusion 401, and the inner side wall of the trapezoid cavity 402 along the short direction of the optical cable section is parallel to the outer side wall of the trapezoid inner protrusion 401;
under the cooperation of the structure, the optical cable can further change the conduction direction of external force along the optical cable structure on the basis of forming deformation buffer;
in particular, the method comprises the steps of,
as shown in fig. 3, when the outer sheath 400 of the ribbon-shaped optical cable receives a force F2 along the short direction of the optical cable section, the trapezoidal outer protrusion 301 is the part which is stressed first except the outer sheath 400 which is stressed directly, and is stressed earlier than the trapezoidal inner protrusion 401 of the outer sheath 400, so that the trapezoidal outer protrusion 301 generates compression deformation along the short direction of the optical cable section, namely along the direction c shown in fig. 3, the existence of the hexagonal cavity 302 can cause the hexagonal cavity 302 to squeeze two trapezoidal inner protrusions 401 adjacent to the trapezoidal outer protrusion 301 along the long direction (the direction d in the drawing), and the two bottom corners of the trapezoidal cavity 402 in the pressed trapezoidal inner protrusion 401 can compress and deform along the long direction (the direction e in the drawing) of the optical cable section, and the side walls of the bottom of the trapezoidal cavity 402 deform upwards along the direction F, so that the compression resistance of the optical cable is greatly improved;
the key point of the effect is that the hexagonal cavity 302 is stressed and deformed earlier than the trapezoidal cavity 402, so that the relative inner and outer positions of the hexagonal cavity 302 and the trapezoidal cavity 402 can be adjusted by arranging the trapezoidal outer protrusions 301 and the trapezoidal inner protrusions 401, and the deformation characteristics of the hexagonal cavity 302 and the trapezoidal cavity 402 are also one of the key points of the effect;
in addition, the hexagonal cavity 302 and the trapezoidal cavity 402 have good structural stability and can play a supporting role, and the deformation force threshold of the ribbon cable is not weakened obviously, so that the arrangement of the structure has a very obvious effect on further strengthening the compression resistance of the ribbon cable.
