[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0030] The skeleton-type hollow-out optical cable of the embodiment of the utility model comprises a sheath 1 , a plurality of carriers 2 and a plurality of optical unit groups 3 .

[0031] The material of the sheath 1 can be polyethylene, polyvinyl chloride, etc., and the sheath 1 is a pipeline structure as a whole. A plurality of carriers 2 are arranged on the peripheral side of the sheath 1 and are arranged at intervals along the circumference of the sheath 1. For example, Figure 1 As shown, the material of the carrier 2 can be the same as that of the sheath 1, and the carrier 2 can be integrally formed with the sheath 1, and a plurality of carriers 2 can be arranged at equal intervals along the circumference of the sheath 1. Each carrier 2 can be in the shape of a long strip, and the extension direction of each carrier 2 can be the same as the extension direction of the sheath 1.

[0032] Each carrier 2 has a distinguishing feature for distinguishing from other carriers 2. For example, the outer surface of the carrier 2 may be provided with a color band, etc. The color band can be regarded as a strip composed of multiple color blocks, and the color band can form a distinguishing feature. The color band on each carrier 2 can be different, so that each carrier 2 can be distinguished.

[0033] The carrier 2 is provided with an inner cavity 21, and the plurality of light unit groups 3 are assembled in the inner cavities 21 of the plurality of carriers 2 in a one-to-one correspondence. Specifically, each carrier 2 may be provided with an inner cavity 21, for example, the carrier 2 may be generally a tubular structure, and the inner space of the carrier 2 forms the inner cavity 21. The number of light unit groups 3 may be the same as the number of carriers 2, and during assembly, the plurality of light unit groups 3 may be fixed in the inner cavities 21 of the plurality of carriers 2, respectively.

[0034] It should be noted that each optical unit group 3 includes multiple optical units 31, and the optical unit 31 may include a microtube, multiple optical fibers, etc., and the multiple optical fibers may be fixed in the microtube. The optical unit 31 in each optical unit group 3 has a distinguishing feature for distinguishing from the remaining optical units 31 in the same optical unit group 3. For example, the color of the outer surface of each optical unit 31 may be different, and the color is the distinguishing feature. When in use, after confirming the optical unit group 3 by confirming the carrier 2, the specific optical unit 31 can continue to be identified by the distinguishing feature in the same optical unit group 3.

[0035] The skeleton-type hollow-out optical cable of the embodiment of the utility model can first identify the corresponding carrier 2 through the distinguishing features when hollow-out splicing is performed, and then the individual optical units 31 in the carrier 2 can be identified through the distinguishing features, thereby avoiding the situation in the prior art where the optical units 31 are difficult to identify when there are a large number of them, and improving the efficiency of hollow-out splicing.

[0036] Secondly, since a large number of light units 31 are distributed in the inner cavities 21 of different carriers 2, the grouping of multiple light units 31 is achieved, and the number of light units 31 in the same independent space is reduced, thereby reducing the friction force between the light units 31 in the same space, which is conducive to increasing the length of the splicing, reducing the difficulty of the splicing, and improving the operability of the splicing.

[0037] In some embodiments, the skeleton-type hollow optical cable includes a plurality of connection parts 4, which are connected one by one between a plurality of carriers 2 and sheaths 1, and the connection parts 4 form a tearable weak structural area to facilitate separation of the carriers 2 and the sheath 1.

[0038] For example, Figure 1 As shown, the connection part 4 can be a strip structure, and the extension direction of the connection part 4 can be the same as the extension direction of the sheath 1. The material of the connection part 4 can be the same as that of the sheath 1 and the carrier 2, that is, the connection part 4 can be integrally formed between the sheath 1 and the corresponding carrier 2. The width of the connection part 4 is small, so that the overall structural strength of the optical cable is small at the connection part 4.

[0039] When the optical cable is spliced, the connecting part 4 between the carrier 2 and the sheath 1 can be torn, and then the carrier 2 can be stripped with the help of a stripping knife or other tool to find the corresponding optical unit 31, and then the subsequent splicing operation can be completed, further improving the convenience of the splicing operation.

[0040] In some embodiments, a plurality of grooves 11 are disposed on the outer peripheral wall of the sheath 1 . The plurality of grooves 11 are arranged at intervals along the circumference of the sheath 1 . The plurality of carriers 2 are embedded in the plurality of grooves 11 in a one-to-one correspondence.

[0041] For example, Figure 1 As shown, there can be three grooves 11, and the three grooves 11 can be arranged at equal intervals along the outer peripheral wall of the sheath 1, each groove 11 can be arranged along the extension direction of the sheath 1, and each groove 11 can be a rectangular groove. The number of grooves 11 can be the same as the number of carriers 2, and during processing, multiple carriers 2 can be integrally formed in multiple grooves 11.

[0042] The groove 11 can hide the carrier 2, preventing the carrier 2 from being exposed and easily touched or disturbed by the outside world, and also preventing the connection part 4 from cracking when the carrier 2 is subjected to lateral force, thereby playing a better protective role.

[0043] In some embodiments, the groove 11 has a notch facing the outer peripheral side of the sheath 1 and a groove bottom wall 111 arranged opposite to the notch, and the connecting portion 4 is connected between the carrier 2 and the groove bottom wall 111. Figure 1 As shown, the notch of the groove 11 can be oriented toward the outer side of the peripheral side of the sheath 1, and the groove bottom wall 111 is the groove wall in the groove 11 that is directly opposite to the groove 11. The inner side of the connecting portion 4 can be connected to the middle of the corresponding groove bottom wall 111, and the outer side of the connecting portion 4 can be connected to the corresponding carrier 2. As a result, the crack development direction formed by the connecting portion 4 when torn is perpendicular to the bending direction of the carrier 2, thereby facilitating the separation of the carrier 2 from the groove 11.

[0044] In some embodiments, the connection portion 4 extends along the extension direction of the sheath 1. For example, the connection portion 4 may be an integrated structure, that is, only one connection portion 4 may be provided between each carrier 2 and the sheath 1, and the connection portion 4 may be strip-shaped and continuously distributed between the corresponding carrier 2 and the sheath 1.

[0045] In some embodiments, the connection portion 4 includes a plurality of connection segments, and the plurality of connection segments are arranged at intervals along the extension direction of the sheath 1. Specifically, each connection portion 4 may be multi-segmented, that is, each connection portion 4 may include a plurality of connection portions 4, and the plurality of connection portions 4 may be arranged at equal intervals along the axial direction of the sheath 1, and each connection segment may be connected between the corresponding carrier 2 and the sheath 1.

[0046] The spaced arrangement of the connecting parts 4 can reduce consumables, thereby reducing material costs, and can also facilitate tearing, thereby facilitating the separation of the carrier 2 and the sheath 1 .

[0047] In some embodiments, the skeleton-type hollow-out optical cable includes a reinforcement member 5, which is embedded in the sheath 1. The extension direction of the reinforcement member 5 is consistent with the extension direction of the sheath 1. For example, Figure 1 As shown, the reinforcement member 5 may be disposed at the center of the jacket 1 and extended along the extension direction of the jacket 1 , and a plurality of carriers 2 are arranged at intervals along the circumference of the reinforcement member 5 .

[0048] The reinforcement member 5 can enhance the tensile strength of the optical cable, thereby preventing the internal optical unit 31 from being torn off when being pulled, and plays a protective role. Secondly, the reinforcement member 5 can also enhance the rigidity of the optical cable.

[0049] In some embodiments, the plurality of carriers 2 are arranged centrally and symmetrically about the strength member 5, thereby ensuring the consistency of the optical cable in all directions and the balance of the structural distribution.

[0050] In some embodiments, the reinforcement member 5 is a metal reinforcement member. For example, the reinforcement member 5 can be a steel wire or the like. The reinforcement member 5 made of metal has a memory function on the one hand, so that the spliced ​​optical cable can be kept in a corresponding bending state after the spliced ​​optical cable is bent. On the other hand, compared with reinforcement members 5 such as reinforced plastic rods, the reinforcement member 5 made of metal also facilitates winding and fixing or splicing and fixing in a splice box, thereby improving the convenience of splicing and fixing.

[0051] In some embodiments, the distinguishing feature includes at least one of the following: color, size, shape. For example, the color of the outer surface of each carrier 2 may be different, so that different carriers 2 can be distinguished and identified.

[0052] In some other embodiments, the radial dimensions of each carrier 2 may be different or the cross-sectional shapes of each carrier 2 may be different, thereby enabling different carriers 2 to be distinguished and identified.

[0053] In some embodiments, the colors of the multiple light units 31 in the same light unit group 3 are different, and the colors constitute distinguishing features. For example, the outer surface of each light unit 31 can be coated with a different color, and different light units 31 can be identified by different colors.

[0054] In some embodiments, the extension direction of the carrier 2 is consistent with the extension direction of the sheath 1, and the extension direction of the inner cavity 21 is consistent with the extension direction of the carrier 2. That is, the central axis of the carrier 2, the central axis of the sheath 1, and the central axis of the inner cavity 21 can all be arranged in parallel, thereby facilitating processing and molding.

[0055] In some embodiments, the outer contour of the cross section of the sheath 1 and the outer contour of the cross section of the carrier 2 are both circular. For example, the cross section of the sheath 1 and the cross section of each carrier 2 can both be circular, thereby ensuring structural consistency and balanced distribution.

[0056] A specific example of a skeleton-type hollow-out optical cable according to an embodiment of the present utility model is described below.

[0057] The trenched optical cable of the embodiment of the utility model comprises a sheath 1 , a plurality of carriers 2 , a plurality of optical unit groups 3 and a reinforcement member 5 .

[0058] A plurality of carriers 2 are arranged inside the sheath 1, and the carriers 2 are distinguished by color, and a plurality of light units 31 are grouped and placed in a plurality of carriers 2 of different colors, so as to help construction personnel quickly locate the space where the light units 31 to be spliced ​​are located. Secondly, the plurality of light units 31 are grouped and stored in a plurality of carriers 2, which reduces the number of light units 31 in a single space, thereby reducing the friction between the light units 31 during splicing, thereby increasing the splicing length and reducing the splicing difficulty.

[0059] The carrier 2 and the sheath 1 of the optical cable are provided with a connecting portion 4, which can be longitudinally continuous or longitudinally spaced. The outer circumference of the sheath 1 is provided with a plurality of grooves 11, and the plurality of carriers 2 are matched in the corresponding grooves 11 one by one.

[0060] When the construction personnel need to perform the splicing operation, they first observe the color of the carrier 2 through the notch of the groove 11 on the sheath 1, and then tear the carrier 2 to be spliced ​​apart by hand to separate the connection portion 4 of the carrier 2 and the sheath 1 to separate the carrier 2 from the groove 11. Then, they use tools such as an optical cable stripper to open the carrier 2, find the optical unit 31 to be spliced, and then perform the subsequent splicing operation.

[0061] A metal reinforcing element is also provided at the center of the sheath 1, so that the hollow-out optical cable can be fixed in the same way as a common outdoor optical cable is fixed in a joint box, which facilitates maintenance by construction personnel.

[0062] The skeleton-type optical cable of the utility model has the following beneficial effects:

[0063] 1. A carrier 2 is disposed inside each of the plurality of grooves 11 of the sheath 1. The light units 31 are grouped and stored in the plurality of carriers 2. The operator can quickly find the light unit 31 to be connected based on the color of the carrier 2 and then the color of the light unit 31. In a weak current room or ceiling with insufficient light, this method can help the operator accurately and quickly identify the light unit 31 to be connected.

[0064] In addition, the plurality of light units 31 are stored in groups, which reduces the number of light units 31 in a single carrier 2, thereby reducing the friction between the light units 31 during splicing, thereby increasing the splicing length and reducing the splicing difficulty.

[0065] 2. A connecting portion 4 is provided between the carrier 2 and the groove 11. The connecting portion 4 can be torn by hand, so that the carrier 2 can be separated from the groove 11, simplifying the digging and splicing steps.

[0066] 3. Ordinary hollow-out optical cables mainly consider the linearity of the optical cable and the problem of sheath 1 cracking. Glass fiber reinforced plastic rods are used to embed them into the sheath wall. However, the disadvantage is that the glass fiber reinforced plastic rods cannot be wound and fixed in the joint box, resulting in the inability to connect ordinary hollow-out optical cables. The hollow-out optical cable of the utility model is provided with a metal reinforcement member in the center of the optical cable, which avoids the risk of reinforcement member exposure and sheath cracking, and the optical cable can be bent in any direction. Secondly, the optical cable can be fixed in the joint box in a conventional manner, which is convenient for optical cable connection.

[0067] Although the above embodiments have been shown and described, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
