And the reinforcing ribs are arranged close to the first space. Therefore, when the optical fiber composite data cable is bent, the optical fiber composite data cable is bent towards the direction opposite to the reinforcing ribs, so that the condition of poor transmission signal of the optical fiber caused by a small bending angle of the optical fiber can be effectively prevented. And the reinforcing ribs are arranged into multiple sections, so that a worker is guided to correctly grasp the bending direction during bending.

Description

Technical Field

[0001] The invention belongs to the technical field of cables, and in particular relates to an optical fiber composite data cable. Background Art

[0002] Fiber optic composite data cable is a cable that realizes ground transmission and fiber optic communication by setting optical fibers and wire cores inside the cable sheath. Existing fiber optic composite data cables generally have a bracket set inside the cable sheath, with the optical fiber set at the center of the bracket and the wire core set in the space inside the bracket. When using this structure, for the convenience of wiring, workers tend to ignore the internal optical fiber, resulting in a small bending angle of the optical fiber (such as 90°), which makes the transmission signal of the optical fiber poor. Summary of the Invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides an optical fiber composite data cable to solve the above-mentioned technical problems.

[0004] In order to achieve the above-mentioned object of the invention, the technical solution provided by the present invention is as follows: A fiber optic composite data cable comprises a bracket and an outer sheath arranged on the outside of the bracket, the bracket comprising a support tube, a plurality of support ribs being circumferentially arranged on the support tube, and an accommodating space being formed between adjacent support ribs, the accommodating space comprising a first accommodating space and a second accommodating space, the first accommodating space being provided with an optical fiber, and the second accommodating space being provided with a wire core; the outer sheath is provided with reinforcing ribs in the length direction of the cable, the reinforcing ribs being arranged in sections in the length direction; the reinforcing ribs being arranged close to the first space.

[0005] Preferably, the distance between two adjacent sections of reinforcing ribs is greater than 2 mm and less than 5 mm.

[0006] Preferably, there are multiple reinforcing ribs.

[0007] Preferably, the outer skin includes an inner sheath, a shielding layer, an insulating layer and an outer sheath which are arranged in sequence from the inside to the outside; and the reinforcing ribs are arranged on the outer sheath.

[0008] Preferably, the inner sheath and the outer sheath are made of polyvinyl chloride.

[0009] Preferably, the insulating layer is made of rubber.

[0010] Preferably, the shielding layer is a metal mesh layer or an aluminum foil layer.

[0011] The optical fiber composite data cable provided by the present invention has an optical fiber arranged in the first space and not at the center of the bracket. Therefore, when the cable is bent, the bending angle of the optical fiber when bending in the direction away from the reinforcing rib is larger than when bending in the direction facing the reinforcing rib. Therefore, bending in the direction away from the reinforcing rib can effectively prevent the occurrence of poor transmission signal of the optical fiber caused by the small bending angle of the optical fiber; by arranging the reinforcing ribs into multiple sections and limiting the distance between two adjacent sections of reinforcing ribs, when the cable is bent in the direction facing the reinforcing ribs, the adjacent reinforcing ribs offset each other and are not easy to bend. When bending in the direction away from the reinforcing ribs, it is relatively easy to bend, thereby guiding the staff to correctly grasp the bending direction when bending.

DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0014] Embodiment, the present invention provides a fiber composite data cable, see Figure 1 and Figure 2, including a bracket and an outer skin 200 arranged on the outside of the bracket, the bracket includes a support tube 101, and a plurality of support ribs 102 are arranged circumferentially on the support tube, and an accommodating space is formed between adjacent support ribs, and the accommodating space includes a first accommodating space 103 and a second accommodating space 104, the first accommodating space is provided with an optical fiber 300, and the second accommodating space is provided with a wire core 400; the outer skin is provided with reinforcing ribs 500 in the length direction of the cable, and the reinforcing ribs are arranged in sections in the length direction; the reinforcing ribs are arranged close to the first space, and in actual production, the distance between two adjacent sections of reinforcing ribs can be set to be greater than 2mm and less than 5mm, such as 3mm or 4mm. Among them, the reinforcing rib can be one, corresponding to the first spatial position, preferably multiple, and the multiple reinforcing ribs generally occupy about 30% of the outer circumference of the outer skin in the circumferential direction.

[0015] When the above optical fiber composite data cable is bent, see Figure 1 Since the optical fiber is arranged in the first space and is not located in the center of the bracket, when the cable is bent, Figure 2 , in the direction facing away from the reinforcement ( Figure 2 When bending in the direction facing the reinforcement ( Figure 2 When bending the fiber (center and upward), the bending angle is large. Therefore, bending the fiber away from the ribs can effectively prevent the poor transmission signal caused by the smaller bending angle. By arranging the ribs into multiple sections and limiting the distance between adjacent sections, the adjacent ribs offset each other when the cable is bent toward the ribs, making it difficult to bend. Bending the cable away from the ribs makes it easier to bend, thus guiding workers to correctly determine the bending direction. In addition, the multiple ribs arranged in sections improve the anti-slip and wear resistance of some parts of the cable surface.

[0016] In one embodiment, the outer sheath comprises, arranged in order from inside to outside, an inner sheath 201, a shielding layer 202, an insulating layer 203, and an outer sheath 204; the reinforcing ribs are disposed on the outer sheath. The inner and outer sheaths are preferably made of polyvinyl chloride (PVC); the insulating layer can be made of rubber; and the shielding layer is a metal mesh or aluminum foil layer. In actual production, the bracket and inner sheath can be integrally formed. The bracket can be made of PVC or an elastic material. If a conductive elastic material (such as a spring) is used, it can also replace the shielding layer.

[0017] In the above embodiment, the outer sheath and the reinforcing ribs can be provided as one piece, and the reinforcing ribs are made of the same material as the outer sheath; the internal space of the support tube can be used to transfer heat when the wire core is heated; in this embodiment, there is one first space and multiple second spaces, and the wire cores in the multiple second spaces can all be data wire cores, or there can be power wire cores, data wire cores, signal wire cores, etc., which can be selected according to actual usage conditions. This is well known to those skilled in the art and is not specifically limited here.
