[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] As shown in the accompanying drawings, the utility model is a non-fusion-jointed optical cable, comprising an outer sheath 1 and a plurality of optical fibers 2, wherein the outer surfaces of the plurality of optical fibers 2 are all provided with a reinforcing sleeve 21, and the plurality of optical fibers 2 are all arranged in the outer sheath 1, wherein a bone strip 3 is arranged in the outer sheath 1, wherein the bone strip 3 comprises a plurality of arranged Minnow cards 31, and the plurality of Minnow cards 31 are connected in sequence, wherein the Minnow cards 31 are preferably made of plastic material, which can reduce the production cost, and the Minnow cards 31 made of plastic material have moderate hardness, wherein an extension plate 301 is arranged at the front end in the length direction of the Minnow cards 31, and a rotating shaft 311 is arranged in the middle of the extension plate 301, wherein the rotating shaft 311 is arranged horizontally, and the Minnow cards 31 are preferably made of plastic material, which can reduce the production cost, and the Minnow cards 31 made of plastic material have moderate hardness, wherein an extension plate 301 is arranged at the front end in the length direction of the Minnow cards 31, and a rotating shaft 311 is arranged horizontally, and the Minnow cards 31 are arranged horizontally, wherein the Minnow cards 31 are ... A jack 312 is provided at the rear end, and the minnow card 31 is provided with a groove 302 at the top of the rear end. A certain gap is left between two adjacent minnow cards 31 to provide a certain rotation space. A plurality of clamping rings 30 are provided at intervals outside the outer sheath 1, at least two clamping rings 30 are provided, and the two clamping rings 30 are respectively provided at both ends of the outer sheath 1 for clamping the two ends of the optical cable, and the two ends of the bone strip 3 correspond to the two clamping rings 30. After the outer sheath 1 is clamped by the clamping ring 30, the two ends of the bone strip 3 can be pressed against to prevent the bone strip 3 from moving along the length direction of the optical cable. The two clamping rings 30 are crimped before leaving the factory. During the laying process, a clamping ring 30 can also be added to the part that needs to be bent.

[0018] The utility model discloses a non-welding optical cable. The bone strip 3 is arranged in an outer sheath 1. The bone strip 3 is used to improve the strength of the optical cable. The bone strip 3 is formed by connecting a plurality of minnows 31 in sequence. When the optical cable is straightened, two adjacent minnows 31 abut against each other to prevent the optical cable from continuing to bend, so that the optical cable can cope with external forces during use. At the same time, the bone strip 3 replaces the arrangement of the reinforcing core to make the optical cable have a certain flexibility. When the optical cable is rolled or laid, the bone strip 3 can be placed on the periphery to bend inwards, which is conducive to rolling and laying, so that the optical cable has a certain strength and flexibility at the same time. When the optical cable is rolled or laid, the bone strip 3 can be bent inwards, and adjacent minnows 31 can rotate with each other while bending. If horizontal laying is required, the bone strip 3 is preferably facing upwards. If outward bending is required during the laying process, the extension plate 301 located at the outward bending position can be broken. The broken extension plate 301 is in the optical cable and does not affect normal use, and can prevent other sections of the bone strip 3 of the optical cable from being affected.

[0019] In this embodiment, the minnow plate 31 is bent, and the top of the minnow plate 31 is close to the inner side of the outer sheath 1, and the front and rear sides of the width direction of the minnow plate 31 are respectively abutted against the outer side of the optical fiber 2. Preferably, the curvature of the minnow plate 31 is less than 180 degrees. When the optical fiber 2 is set to three, the front and rear sides of the minnow plate 31 in the width direction are respectively abutted against the outer sides of any two adjacent optical fibers 2. When the optical fiber 2 is set to four or more, that is, Figure 1 As shown in FIG. 5 , the inner side of the Minnow card 31 abuts against the outer side of one optical fiber 2 , and the front and rear sides respectively abut against the outer sides of two optical fibers 2 adjacent to the optical fiber 2 .

[0020] like Figure 2 As shown, the rotating shaft 311 of one of the minnow cards 31 is rotatably connected to the insertion hole 312 of the other minnow card 31, and the extension plate 301 abuts against the groove 302. The two adjacent minnow cards 31 are rotatably connected through the rotating shaft 311 and the insertion hole 312. When the two minnow cards 31 rotate to the same straight line, the extension plate 301 of one of the minnow cards 31 abuts against the groove 302 of the other minnow card 31, so that it cannot continue to rotate.

[0021] In this embodiment, a waterproof isolation layer 11 is disposed inside the outer sheath 1 , and the waterproof isolation layer 11 is filled with waterproof rubber 101 .

[0022] In this embodiment, the reinforcement sleeve 21 is made of a fiber composite material, and a loose sleeve 201 is arranged between the optical fiber 2 and the reinforcement sleeve 21. The reinforcement sleeve 21 is made of a fiber composite material so that it has a certain hardness. At the same time, a loose sleeve 201 is arranged between the reinforcement sleeve 21 and the optical fiber 2 to prevent the reinforcement sleeve 21 from directly contacting the optical fiber 2.

[0023] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
