Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a prefabricated branched cable. Background Technology

[0002] Prefabricated branched cables are cables manufactured in factories according to the main and branch cable models, specifications, cross-sections, lengths, and branch positions required by the cable users. They are produced on an assembly line using a series of specialized production equipment.

[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Existing branch cables are mostly used by branching the main cable at appropriate locations according to site requirements. Subsequently, after branching, workers secure the branched cables with tape. During the branching process, it is impossible to modify the branch cable joints according to changes in the construction site, thus increasing the limitations of the device. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a prefabricated branch cable.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a prefabricated branch cable, including a main cable and a branch cable, wherein one end of the main cable and one end of the branch cable merge to form a combined cable, an insulation layer is sleeved on the outer wall of both the main cable and the branch cable, a protective sleeve is sleeved on the outer wall of the insulation layer, a dividing member is provided on the outer wall of the main cable, a through hole is provided through the side wall of the dividing member, the main cable passes through the through hole and is slidably connected to the through hole, an installation hole is provided through the side wall of the dividing member, and the branch cable passes through the installation hole and is slidably connected to the installation hole.

[0006] By adopting the above technical solution, when workers need to branch the cable, they need to place the splitter onto the main cable. Then, workers separate the branch cable from the main cable, and further pass the branch cable through the splitter. During this process, workers can change the position of the cable branch by sliding the splitter, and thus adjust the cable splitting points on-site, thereby reducing the limitations of the device.

[0007] Furthermore, a clamping groove is provided on the inner wall of the through hole, and a clamping block is slidably disposed in the clamping groove, with the side wall of the clamping block abutting against the outer wall of the main cable.

[0008] Furthermore, a bolt is threaded through the outer wall of the segment, one end of the bolt extends into the clamping groove, and the other end of the bolt is rotatably connected to the clamping block.

[0009] By adopting the above technical solution, once the segmentation node is determined, the operator slides the segmenting component to the appropriate position. Then, the operator rotates the bolt, causing it to move closer to the main cable. This causes the clamping block to slide along with the bolt, pressing against the outer wall of the main cable. This increases the friction between the clamping block and the main cable, reducing the probability of the segmenting component sliding under external forces during use, thus improving the stability of the device.

[0010] Furthermore, a rotating groove is provided on the side wall of the clamping block near the bolt, and an annular groove is provided on the inner wall of the rotating groove. The bolt is rotatably connected to the rotating groove, and an annular block is rotatably arranged in the annular groove. The annular block is fixed to the bolt.

[0011] By adopting the above technical solution, when the operator rotates the bolt, the annular block rotates synchronously with the bolt under the action of the bolt. During this process, the side wall of the annular block abuts against the inner wall of the annular groove, thereby limiting the bolt by the annular block, thus reducing the probability of the clamping block and the bolt separating when the operator rotates the bolt, and thus improving the stability of the device.

[0012] Furthermore, a rubber sheet is fixedly provided on the side wall of the clamping block away from the bolt.

[0013] By adopting the above technical solution, the rubber has good elasticity, and the rubber sheet made of rubber material increases the upper limit of the maximum static friction between the clamping block and the main cable, thereby further reducing the probability of the segment sliding when subjected to external force, thus improving the stability of the device.

[0014] Furthermore, the outer walls of both the main cable and the branch cables are wrapped with a protective layer.

[0015] By adopting the above technical solution, the protective layer can protect the main cable and branch cables, thereby reducing the probability of damage to the main cable and branch cables during use and extending the service life of the main cable and branch cables.

[0016] Furthermore, the outer wall of the protective sleeve is coated with fluorescent powder.

[0017] By adopting the above technical solution, the phosphor reduces the difficulty for staff to find the crack point when the protective layer is broken, thereby reducing the workload of the staff.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In this application, when workers need to branch the cable, they need to place the splitter onto the main cable. Then, workers separate the branch cable from the main cable, and further, they pass the branch cable through the splitter. During this process, workers can change the position of the cable branch by sliding the splitter, and thus adjust the cable splitting points on-site, thereby reducing the limitations of the device.

[0020] 2. In this application, after the segmentation node is determined, the operator slides the segmentation component to the appropriate position. Subsequently, the operator needs to rotate the bolt, which moves the bolt closer to the main cable. This causes the clamping block to slide along with the bolt towards the main cable under the action of the bolt, thereby pressing the clamping block against the outer wall of the main cable. This increases the friction between the clamping block and the main cable, thereby reducing the probability of the segmentation component sliding under external force during use, thus improving the stability of the device.

[0021] 3. In this application, when the operator rotates the bolt, the annular block rotates synchronously with the bolt under the action of the bolt. During this process, the side wall of the annular block abuts against the inner wall of the annular groove, thereby limiting the bolt by the annular block, thus reducing the probability of the clamping block separating from the bolt when the operator rotates the bolt, thereby improving the stability of the device.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-4 As shown in the illustration, this application discloses a prefabricated branch cable, including a main cable 1, a branch cable 11, an insulation layer 12, a protective sleeve 13, a dividing member 14, a clamping block 3, a bolt 4, and an annular block 5. One end of the main cable 1 and one end of the branch cable 11 merge to form a combined cable. Two insulation layers 12 are provided and respectively sleeved on the outer walls of the main cable 1 and the branch cable 11. Two protective sleeves 13 are provided and respectively sleeved on the outer walls of the two insulation layers 12. The dividing member 14 is disposed on the outer wall of the main cable 1. A through hole 2 is provided through the side wall of the dividing member 14, through which the main cable 1 passes and is slidably connected. A mounting hole 21 is provided through the side wall of the dividing member 14, through which the branch cable 11 passes and is slidably connected.

[0029] When workers need to branch the cable, they need to put the splitter 14 on the main cable 1. Then, the workers split the branch cable 11 from the main cable and pass the branch cable 11 through the splitter 14. During this process, the workers can change the position of the cable branch by sliding the splitter 14, and thus adjust the cable splitting node on the construction site, thereby reducing the limitations of the device.

[0030] A clamping groove 22 is provided on the inner wall of the through hole 2. The clamping block 3 is a rectangular block structure. The clamping block 3 is slidably disposed in the clamping groove 22. The side wall of the clamping block 3 is clamped to the outer wall of the main cable 1.

[0031] Bolt 4 is threaded through and installed on the outer wall of the dividing piece 14. Its axis is vertical. One end of bolt 4 extends into the clamping groove 22 and is rotatably connected to the clamping block 3.

[0032] Once the dividing point is determined, the operator slides the dividing component 14 to the appropriate position. Then, the operator rotates bolt 4, causing it to move closer to the main cable 1. This causes the clamping block 3 to slide along with bolt 4 towards the main cable 1, thus pressing against the outer wall of the main cable 1. This increases the friction between the clamping block 3 and the main cable 1, reducing the probability of the dividing component 14 sliding under external forces during use, thereby improving the stability of the device.

[0033] A rotating groove 23 is provided on the side wall of the clamping block 3 near the bolt 4. An annular groove 24 is provided on the inner wall of the rotating groove 23, and the bolt 4 is rotatably connected to the rotating groove 23. The annular block 5 is a circular structure with its axis coinciding with the axis of the bolt 4. The annular block 5 is rotatably disposed in the annular groove 24, and the annular block 5 is fixed to the bolt 4.

[0034] When the operator rotates the bolt 4, the annular block 5 rotates synchronously with the bolt 4 under the action of the bolt 4. During this process, the side wall of the annular block 5 abuts against the inner wall of the annular groove 24, thereby limiting the bolt 4 by the annular block 5, which reduces the probability of the clamping block 3 and the bolt 4 separating when the operator rotates the bolt 4, thus improving the stability of the device.

[0035] To improve the stability of the device, a rubber sheet 6 is fixedly installed on the side wall of the clamping block 3 away from the bolt 4. Rubber has good elasticity, and the rubber sheet 6 made of rubber increases the upper limit of the maximum static friction force between the clamping block 3 and the main cable 1, thereby further reducing the probability of the dividing piece 14 sliding when subjected to external force, thus improving the stability of the device.

[0036] To extend the service life of the main cable 1 and the branch cable 11, a protective layer is wrapped around the outer wall of both the main cable 1 and the branch cable 11. The protective layer protects the main cable 1 and the branch cable 11, thereby reducing the probability of damage to the main cable 1 and the branch cable 11 during use, and thus extending their service life.

[0037] To reduce the workload for workers, fluorescent powder is applied to the outer wall of the protective sleeve 13. The fluorescent powder reduces the difficulty for workers to locate the breakage point if the protective layer is damaged, thus reducing the workload for workers.

[0038] The operating principle of a prefabricated branch cable in this embodiment is as follows: When workers need to branch the cable, they need to place the dividing piece 14 onto the main cable 1. Then, the workers separate the branch cable 11 from the main cable and pass it through the dividing piece 14. During this process, workers can change the position of the cable branch by sliding the dividing piece 14, and adjust the cable branching node on-site. Once the branching node is determined, the workers slide the dividing piece 14 to the appropriate position. Then, the workers rotate the bolt 4, causing it to move closer to the main cable 1. This causes the clamping block 3 to slide along with the bolt 4, pressing against the outer wall of the main cable 1. This increases the friction between the clamping block 3 and the main cable 1, reducing the probability of the dividing piece 14 sliding under external force during use, thus improving the stability of the device.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
