Examples
A flat ribbon cable as shown in fig. 1, comprising in particular:
sheath 100, support unit set 200, and core wire;
the sheath 100 is elliptical, and a central cavity 101 adapted to the supporting unit group 200 is arranged in the sheath 100, and the supporting unit group 200 is arranged in the central cavity 101 of the sheath 100 along the long axis direction of the sheath 100;
the supporting unit group 200 is divided into a middle unit 202 and side units 201, and the side units 201 are arranged at two ends of the supporting unit group 200 along the long axis direction of the sheath 100;
the middle parts of the middle unit 202 and the side unit 201 are respectively provided with a spindle-shaped supporting body 2011 (2021);
the core wire is arranged in the spindle-shaped supporting body 2011 (2021), and is composed of a wire body with an elliptical cross section and an optical fiber ribbon embedded in the wire body, parallel to the short axis direction of the wire body and arranged in the long axis direction of the wire body;
the long axis of the core wire body points to two tips of the spindle-shaped supporting body 2011 (2021), two ends of the core wire body in the long axis direction are not contacted with the inner wall of the spindle-shaped supporting body 2011 (2021), and two ends of the core wire body in the short axis direction are abutted with the inner wall of the spindle-shaped supporting body 2011 (2021);
the side walls of the side units 201 extend tangentially towards the center of the sheath 100 to form outer ribs, the side walls of the middle unit 202 extend tangentially to form outer ribs, and the adjacent side units 201 and/or the outer ribs of the middle unit 202 are mutually abutted, so that the side walls and the outer ribs of the spindle-shaped supporting bodies 2011 (2021) of the adjacent side units 201 and/or the middle unit 202 form a closed space;
the closed space serves as a buffer space for supplying buffer deformation to the ribbon cable, and when the optical cable is pressed, the supporting unit group 200 is contracted so as not to generate excessive pressing force to the core wires in the supporting unit group 200;
in the technical scheme of the invention, when the ribbon is twisted, because of the structural characteristics of the supporting unit group 200, especially the abutting of the outer ribs and the formation of a closed space, a rigid supporting point is formed to resist torsional deformation, and meanwhile, the ribbon has the capability of shrinking along the long axis of the sheath 100, so that when the ribbon is twisted, the sheath 100 can shrink along the long axis direction of the sheath 100 due to the supporting unit group 200, the whole sheath 100 tends to deform into a circular sheath 100 instead of driving each intermediate unit 202 and/or the side unit 201 in the supporting unit group 200 to twist core wires in the ribbon, thereby avoiding possible torsional damage of the fiber ribbon;
further, the method comprises the steps of,
the outer rib of the middle unit 202 and the outer rib and/or the outer side wall of the spindle-shaped support body 2021 are/is provided with a tightening reinforcement 400 in a penetrating manner along the axial direction of the belt cable, and the arrangement of the reinforcement 400 can further improve the compression resistance of the belt cable, so as to improve the arrangement stability of the reinforcement 400 between the outer rib and the spindle-shaped support body 2021, as shown in fig. 3, a sleeve 2022 is arranged outside the reinforcement 400, the sleeve 2022 is fixedly connected with the outer rib and the spindle-shaped support body 2021, the reinforcement 400 is stably arranged between the outer rib and the spindle-shaped support body 2021, and due to the shape and structure characteristics of the spindle-shaped support body 2021, as shown in fig. 4, even if the reinforcement 400 is compressed and drives the reinforcement 400 to generate displacement, the reinforcement 400 arranged between the spindle-shaped support body 2021 and the outer rib is easy to slide along the outer side wall of the spindle-shaped support body 2021, the reinforcement 400 between the outer rib and the outer rib is fixedly arranged between the outer rib and the spindle-shaped support body 2021, and the spindle-shaped support body 2021 can directly press the spindle-shaped support body 2021 (the inner side of the spindle-shaped support body 2011 is prevented from being stressed by a certain amount, and the inner core wire can directly bear the inner side of the spindle-shaped support body 2011;
in addition, as shown in fig. 5, the reinforcement 400 is further arranged to avoid the twisting of the middle unit 202, which has a good positioning and fixing effect on the spindle-shaped supporting body 2021 of the middle unit 202, and the middle unit 202 itself and the central cavity 101 cooperate to effectively limit the deformation and displacement of the side unit 201, that is, simultaneously limit the twisting of the spindle-shaped supporting body of the side unit 201, and no reinforcement 400 is arranged between the outer rib of the side unit 201 and the outer wall of the spindle-shaped supporting body 2011, mainly to ensure that the side unit 201 can be more conveniently displaced towards the cable core portion, that is, the side unit 201 is close to the middle unit 202 and the whole supporting unit group 200 is compressed along the long axis direction of the sheath 100.
Still further, the method comprises the steps of,
the two sides of the supporting unit group 200 along the long axis direction of the sheath 100 are respectively provided with an arc-shaped side cavity 102, the arc-shaped two ends of the side cavity 102 are respectively provided with a metal reinforcing wire 300 along the axial direction of the belt cable, the metal reinforcing wires 300 and the side cavities 102 mainly play roles in limiting the supporting unit group 200 at the two ends of the sheath 100 in the long axis direction and promoting the sheath 100 to deform circularly, and in the torsion process of the belt cable, the metal reinforcing wires 300 are compressed inwards along the long axis direction of the sheath 100 due to the existence of the side cavities 102 and the metal reinforcing wires 300, so that the compression gathering of the supporting unit group 200 is driven;
in view of the above, the present invention aims to ensure that the cable has basic compression resistance, and at the same time, significantly improve the torsion resistance, and ensure that when the cable sheath 100 is stressed to twist, the torsion of the core and the optical fiber ribbon inside the core can be inhibited by proper deformation and buffering.
