Examples
A ribbon cable as shown in fig. 1, comprising in particular:
the cable sheath comprises a sheath layer 100 with a round-cornered rectangular section, wherein the long rectangular sides of the sheath layer 100 respectively correspond to the upper side and the lower side of the optical cable, the middle part of the lower side of the sheath layer is provided with an embedding groove 101, and an external reinforcement 200 is embedded in the embedding groove 101;
the caulking groove 101 is in a semicircular shape with a flat bottom surface 201 facing outwards on the cross section of the optical cable, the outer reinforcing piece 200 is matched with the caulking groove 101, the outer reinforcing piece 200 is completely accommodated in the caulking groove 101, namely, the outer reinforcing piece 200 is retracted into the caulking groove 101, the flat bottom surface 201 of the outer reinforcing piece is not flush with the notch of the caulking groove 101, and when the optical cable is placed on a bearing surface (such as the ground), because space allowance exists between the outer reinforcing piece 200 and the bearing surface, when the optical cable is impacted from top to bottom, the impact resistance and the buffering effect can be formed; if the flat bottom surface 201 of the outer reinforcement member 200 is flush with the notch of the caulking groove 101 or extends out of the caulking groove 101, when the optical cable is impacted, the outer reinforcement member 200 mainly plays a role in supporting, and at the moment, the optical cable cannot form other impact resistance effects except for self deformation buffering, by adopting the arrangement mode of the invention, the outer reinforcement member 200 can firstly play an axial shaping role, when the optical cable is impacted from top to bottom or under strong external force, as shown in fig. 2, the outer reinforcement member 200 can generate weak displacement along with the deformation of the sheath layer 100 and further contact the bearing surface, so that most of the impact force is converted into the impact force of the outer reinforcement member 200 on the bearing surface, and further the effects of pressure resistance and impact resistance are realized;
the outer side of the sheath layer 100 is also selectively coated with a functional cover 102 for identifying color or playing a role in water resistance, oxidation resistance and the like;
in the sheath layer 100, a plurality of line cavities 103 are symmetrically arranged along two sides of the long side direction of the cross section of the sheath layer 100 by taking the caulking groove 101 as a center;
an optical fiber line 300 for transmitting optical signals and realizing a communication function is arranged in the line cavity 103;
the optical fiber line 300 is formed by bundling a single or a plurality of optical fibers by an inner bundling tube, the optical fiber line 300 is externally coated with an outer bundling tube 400, the outer bundling tube 400 and the inner bundling tube are concentrically arranged, a plurality of fillers 500 are arranged between the outer bundling tube 400 and the inner bundling tube, and the inner bundling tube 400 and the outer bundling tube 400 are made of silicon rubber materials;
in particular, the method comprises the following steps of,
the filler 500 comprises a hollow micro-tube and a filling line, the filling line is arranged on the inner layer and attached to the outer wall of the inner beam tube, and the hollow micro-tube is arranged on the outer layer and attached to the inner wall of the outer beam tube 400;
the wire cavity 103 is in a water-drop shape on the cross section of the sheath layer 100, the tip 1031 of the wire cavity is opposite to the caulking groove 101 and faces outwards along the long side direction of the sheath layer 100, a plurality of cushion strips 1032 used for separating the wire cavity 103 from the outer tube bundle 400 are further arranged in the wire cavity 103, the cushion strips 1032 are made of flexible materials, specifically, the wire cavity is made of ultra-soft vulcanized rubber, the cushion strips 1032 are arranged along the circumferential direction of the outer tube bundle 400 in a laminating mode and are abutted outwards against the arc-shaped inner wall of the wire cavity 103, but the tip 1031 of the wire cavity 103 is not filled in the wire cavity 103, and the cushion strips 1032 are not arranged on one side, facing the caulking groove 101, of the wire cavity 103 along the long side direction of the sheath layer 100;
when the optical cable is pressed from top to bottom, the drop-shaped wire cavity 103 has a unique guiding deformation tendency, the tip 1031 has a larger deformation ratio, when the tip 1031 is not provided with the pad strip 1032, the tip 1031 is more easily compressed, after the pad strip 1032 is provided, because the elasticity of the pad strip 1032 is higher than that of the outer bundle tube 400, the pad strip 1032 first plays a role of buffering, so that the outer bundle tube 400 is not easily deformed by direct force, furthermore, the outer bundle tube 400 is prepared by silicon rubber and has a hardness much higher than that of super soft vulcanized rubber, as shown in fig. 2, when the wire cavity 103 is deformed, it can be seen that the optical fiber wires 300 in the outer bundle tube 400 and the outer bundle tube 400 move towards the direction where the pad strip 1032 is not arranged on one side of the caulking groove 101 under the extrusion of the pad strip 1032, so that the deformation direction is controllable, and under the cooperation of the above structures and materials, when the optical cable is subjected to force, the tip 1031 of the wire cavity 103 is more easily compressed, and the deformation thereof can push the pad strip 1032 and the outer bundle tube 400 to move towards the direction away from the tip 1031, so that the outer bundle tube 400 and the inner optical fiber line 300 are not substantially affected by the force;
between the outer tube bundle 400 and the inner tube bundle, the filler 500 is a solid filling line and a hollow micro tube, because the solid filling line can play a direct buffering role, the effect is equivalent to that of the conventional optical cable filling line, and the hollow micro tube can generate a stronger buffering role through certain deformation;
if the hollow micro-tube is simply directly arranged on the outer surface of the optical fiber line 300, although the hollow micro-tube can generate the function of deformation buffering, the elastic restoring force of the hollow micro-tube is easily transmitted to the outer surface of the optical fiber line 300, so that the optical fiber line 300 is easily damaged, the elastic restoring force of the hollow micro-tube can be further dispersed by adopting the filling line, the filling line which is arranged in the hollow micro-tube and is matched with the hollow micro-tube has a certain dispersing force function, and after the positions of the filling line and the hollow micro-tube are mutually exchanged, the filling line still has the function of dispersing the elastic restoring force of the hollow micro-tube, but the protection object is changed into the outer bundle tube 400, so that the protection effect on the optical fiber line 300 is poor.
Further, in the above-mentioned case,
the sheath layer 100 is provided with an inner groove 104 corresponding to the upper end of the caulking groove 101, the inner groove 104 is in an upward arched arc shape, the lower side wall 1041 of the inner groove 104 faces the caulking groove 101, the radian of the lower side wall 1041 is smaller than that of the upper side wall 1042, an inner reinforcement 600 is arranged in the inner groove 104, the inner reinforcement 600 is prepared by elastic silicon rubber, and the inner reinforcement 600 is attached to the lower side wall 1041 of the inner groove 104 and is separated from the upper side wall 1042;
two side grooves 105 which are arched towards the direction of the inner groove 104 are respectively arranged on two sides of the inner groove 104 along the long side direction of the cross section of the sheath layer 100;
the side groove 105 is U-shaped or U-like, the inner side wall 1051 faces the inner groove 104, the outer side wall 1052 faces away from the inner groove 104, a V-shaped or V-like side reinforcing member 700 is arranged in the side groove 105, and the side reinforcing member 700 is attached to the inner side wall 1051 of the side groove 105 and is separated from the middle part of the outer side wall 1052;
the edge reinforcement 700 and the inner reinforcement 600 are both made of elastic silicone rubber, so that the effect of deformation buffering when the optical cable is stressed is achieved, when the optical cable is under the action force from top to bottom, the inner groove 104 is compressed and deformed, the inner reinforcement 600 tends to be straightly deformed until the inner reinforcement 600 is directly stressed, in the deformation process, the edge reinforcement 700 is gradually attached to the outer wall of the edge groove 105, the edge reinforcement 700 is deformed to achieve the effect of up-and-down supporting, as shown in fig. 3, the uppermost end and the lowermost end of the edge reinforcement 700 are respectively higher than and lower than the uppermost end and the lowermost end of the wire cavity 103, so that the longitudinal force effect borne by the wire cavity 103 can be reduced, meanwhile, the matching arrangement of the inner groove 104-inner reinforcement 600 and the edge groove 105-edge reinforcement 700 can avoid the concentrated stress in the middle part of the optical cable, so that the wire cavity 103 cannot generate the deformation tendency, and further avoid the problem of the damage of the optical fiber wire 300, meanwhile, the upper limit of the longitudinal supporting capacity of the optical cable is improved, the deformed edge reinforcing member 700 can also show the advantage of preferential stress of a rigid structure relative to the optical cavity 103, can directly transmit part of force borne by the upper end of the optical cable to the lower end of the optical cable by 'crossing' the optical cavity 103, and has a very excellent protection effect on the optical fiber 300 in the optical cavity 103;
in addition, the inner groove 104-inner strength member 600 and the side groove 105-side strength member 700 can maintain the flexible storage characteristic of the optical fiber ribbon cable, compared with other conventional rigid strength members, and do not cause significant hardening of the entire optical fiber cable.
