Description

Technical Field

[0001] This utility model relates to the field of cable head reinforcement technology, specifically a reinforced cable for ship cable heads. Background Technology

[0002] Shipboard cable terminations primarily use materials such as polyvinyl chloride (PVC) and cross-linked polyethylene (XLPE) as insulation layers. While these materials provide good insulation performance under certain conditions, their performance may degrade under high humidity, high temperature, or long-term use, leading to insulation failure. To improve the insulation performance of cable terminations, new insulation materials, such as silicone rubber and fluoroplastics, have been gradually introduced into the market. These materials exhibit excellent performance in terms of high temperature resistance and corrosion resistance. However, existing technologies still have some shortcomings, such as insufficient durability and breakdown resistance under high loads, and susceptibility to aging and embrittlement during long-term use. Furthermore, although some cable terminations employ sealed designs to enhance waterproofing, the intrusion of moisture and corrosive substances in harsh marine environments remains a potential risk.

[0003] Chinese utility model patent, publication number "CN219918392U", discloses a reinforced cable for shipboard cable heads. The technical solution includes: a cable body; a fixing component at the end connection of the cable body; the cable consists of a conductor and an insulating sleeve; a connector is provided at the end of the conductor; a corrugated tube is provided at the end of the insulating sleeve; the connector is located inside the corrugated tube; the fixing component is disposed between the insulating sleeves; and a double-ended screw is used at the cable connection for reinforcement. This design prevents the connection from breaking under tension, ensuring connection stability and making it more suitable for the unstable working environment on ships. Simultaneously, the sealing structure increases the sealing performance of the connection, preventing water ingress.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] Although the above-mentioned device can reinforce the cable connection, it is too modular and each structure is an independent part. The fixing operation is very troublesome during use, the parts are easy to lose, and its fixing performance is poor. Utility Model Content

[0006] The purpose of this utility model is to provide a reinforced cable for shipboard cable heads to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A reinforced cable for shipboard cable heads includes a cable insulation sleeve, a core wrapped inside the cable insulation sleeve, a fixed sleeve movably fitted on the cable insulation sleeve, and a fixing component for fixing the cable insulation sleeve inside the fixed sleeve.

[0009] The two fixed sleeves are connected by a connecting sleeve, and the surface of the fixed sleeve and the inner wall of the connecting sleeve are provided with mutually mating connecting threads;

[0010] The two cores are fixed together by a connecting sleeve and fixing screws.

[0011] Preferably, the fixing component includes a clamping block movably disposed inside the fixing sleeve, and the clamping block has an arc-shaped groove for clamping the cable insulation sleeve;

[0012] A connecting post is fixedly installed on the clamping block, and an adjusting screw is rotatably connected to the connecting post. A threaded hole is provided on the fixed sleeve for the adjusting screw to pass through.

[0013] Preferably, the fixed sleeve has a plurality of contraction grooves at the end away from the connecting thread, the fixed sleeve has an adjusting thread, and a threaded sleeve adapted to the adjusting thread is movably fitted on the fixed sleeve.

[0014] The outer diameter of the end of the fixed sleeve with the shrinkage groove is larger than the inner diameter of the threaded sleeve. The fixed sleeve is fitted onto the cable insulation sleeve. By rotating the threaded sleeve, the threaded sleeve moves toward the shrinkage groove, squeezing the fixed sleeve to squeeze and fix the cable insulation sleeve.

[0015] Preferably, the inner wall of the fixed sleeve at the shrink groove end is provided with a plurality of slots, and a locking block is movably locked inside the slot, and a rubber block is fixedly installed on the locking block.

[0016] Preferably, a number of anti-slip rubber strips are fixedly provided at intervals on the inner wall of the arc-shaped groove.

[0017] Preferably, the outer wall of the connecting sleeve is provided with a plurality of anti-slip strips.

[0018] Preferably, the fixed sleeve is provided with a limiting block for limiting the threaded sleeve.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. With two fixed sleeves and one connecting sleeve, the other threaded sleeves, clamps, and adjusting threads are all located inside. During use, simply tightening the threads or threaded sleeves is enough to fix the insulation sleeves of the two cables that need to be connected. The entire device has only three main modules, which are not easy to lose and are simple to use. Then, under the action of the connecting sleeve, the two fixed sleeves move closer to each other at a certain distance while fixing the cable insulation sleeves, ensuring that the two cables that need to be connected are wrapped and connected, preventing the connection from loosening and breaking.

[0021] 2. The insulation sleeves of the two cables to be connected are fixed by the fixing component. Then, by turning the threaded sleeve, the shrinking end of the fixing sleeve is tightened, which further fixes the cable insulation sleeves.

[0022] 3. By using the locking blocks and rubber blocks, when the cable insulation sleeve to be fixed is thin, the locking blocks can be inserted into the slots, allowing the contracted end of the fixing sleeve to better fix the cable insulation sleeve. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-7 This utility model provides a technical solution:

[0033] A reinforced cable for shipboard cable heads includes a cable insulation sleeve 1, a core 2 wrapped inside the cable insulation sleeve 1, a fixed sleeve 3 movably fitted on the cable insulation sleeve 1, and a fixing component for fixing the cable insulation sleeve 1 inside the fixed sleeve 3. The two cores 2 are fixed together by a connecting sleeve 6 and a fixing screw 7.

[0034] In this embodiment, the cable insulation sleeve 1 is used to wrap and fix the core 2. In the conventional setting of the cable body, when the two cores 2 need to be connected, the two cores 2 are first inserted into the connecting tube 6, and then the fixing screws 7, which are movably set on the connecting tube 6, are tightened to fix them. At this time, the connection between the two cores 2 is completed. In the process of use, if the two cores 2 are connected and fixed by the connecting tube 6 alone, it is very unstable. When the cable is subjected to external tension, it is very easy to break and fall off. Therefore, in this embodiment, the fixing sleeve 3 and the connecting sleeve 4 are set to fix the connection of the cores 2 by tightening the cable insulation sleeve 1.

[0035] The two fixed sleeves 3 are connected by a connecting sleeve 4. The surface of the fixed sleeve 3 and the inner wall of the connecting sleeve 4 are provided with mutually matching connecting threads 5. Several anti-slip strips 20 are provided on the outer wall of the connecting sleeve 4.

[0036] In this embodiment, two fixed sleeves 3 fix the cable insulation sleeves 1 on both sides. Then, by rotating the connecting sleeve 4, the fixed sleeves 3 on both sides can drive the cable insulation sleeves 1 to move closer to each other by a certain distance, ensuring that the external tension will not directly act on the connection of the core 2. At the same time, after the connection is completed, the connecting sleeve 4 can protect the connection of the core 2. At this time, the connection of the core 2 is inside the connecting sleeve 4, in a sealed space, which can not only prevent damage from external forces, but also play a certain waterproof role. If it is necessary to enhance the waterproof effect, waterproof glue can be applied to the connection between the connecting sleeve 4 and the fixed sleeve 3 to achieve better waterproofing.

[0037] The fixing assembly includes a clamping block 8 movably disposed inside the fixing sleeve 3. The clamping block 8 has an arc-shaped groove 9 for clamping the cable insulation sleeve 1. Several anti-slip rubber strips 19 are fixedly disposed at intervals on the inner wall of the arc-shaped groove 9. A connecting post 10 is fixedly disposed on the clamping block 8. An adjusting screw 11 is rotatably connected to the connecting post 10. The fixing sleeve 3 has a threaded hole 12 for the adjusting screw 11 to pass through. Several contraction grooves 13 are provided at the end of the fixing sleeve 3 away from the connecting thread 5. An adjusting thread 14 is provided on the fixing sleeve 3. A threaded sleeve 15 that matches the adjusting thread 14 is movably fitted on the fixing sleeve 3.

[0038] The outer diameter of one end of the fixed sleeve 3 with the shrinkage groove 13 is larger than the inner diameter of the threaded sleeve 15. The fixed sleeve 3 is fitted onto the cable insulation sleeve 1. By rotating the threaded sleeve 15, the threaded sleeve 15 moves toward the shrinkage groove 13, squeezing the fixed sleeve 3 to squeeze and fix the cable insulation sleeve 1. The fixed sleeve 3 is provided with a limiting block 21 for limiting the threaded sleeve 15.

[0039] In this embodiment, the connecting column 10 ensures that the adjusting screw 11 can be movably mounted on the fixed sleeve 3. After the position of the fixed sleeve 3 is adjusted, the operator turns the adjusting screw 11. At this time, the adjusting screw 11 drives the clamping blocks 8 to move closer to each other, and the cable insulation sleeve 1 is fixedly clamped through the arc groove 9. At the same time, the operator turns the threaded sleeve 15. Under the action of the adjusting thread 14, the threaded sleeve 15 moves closer to the contraction groove 13 end of the fixed sleeve 3. Initially, the contraction groove 13 end of the fixed sleeve 3 is in an open state. Here, the outer diameter of the fixed sleeve 3 is larger than the inner diameter of the threaded sleeve 15. Under the action of the threaded sleeve 15, the contraction end of the fixed sleeve 3 is squeezed. At this time, the contraction end contracts, further clamping and fixing the cable insulation sleeve 1, further ensuring the clamping effect of the fixed sleeve 3 on the cable insulation sleeve 1. At the same time, the anti-slip rubber strip 19 ensures the anti-slip effect at the fixing point.

[0040] The limit block 21 is designed to prevent the threaded sleeve 15 from slipping off the adjusting thread 14.

[0041] The inner wall of the fixed sleeve 3 located at the end of the shrink groove 13 is provided with several slots 16, and a locking block 17 is movably locked inside the slot 16. A rubber block 18 is fixedly installed on the locking block 17.

[0042] In this embodiment, considering that the cable insulation sleeve 1 has different thicknesses, when encountering a thin cable insulation sleeve 1, even if the contracted end of the fixing sleeve 3 is fully contracted, it cannot fix the cable insulation sleeve 1. Therefore, a slot 16 is set up. By inserting a block 17 with a rubber block 18 into the slot 16, the thickness of the inner wall is increased, ensuring that the cable insulation sleeve 1 can be better clamped. The thickness of the rubber block 18 can be set to different sizes, and can be adjusted appropriately in actual use.

[0043] Working principle: In the process of using this device, a fixed sleeve 3 and a connecting sleeve 4 are first placed on a cable insulation sleeve 1, and then another fixed sleeve 3 is placed on another cable insulation sleeve 1.

[0044] At this point, the operator inserts the two cores 2 into the inside of the connecting cylinder 6, and then tightens the fixing screws 7 to fix the cores 2 inside the connecting cylinder 6.

[0045] At this point, move the connecting sleeve 4 to the position where it covers the connecting sleeve 6, which is the connection point of the two cores 2, ensuring that the connecting sleeve 4 can cover the connection point of the cores 2. Then, pre-connect the two fixed sleeves 3 and the connecting sleeve 4, that is, connect the fixed sleeves 3 and the connecting sleeve 4 through the connecting thread 5.

[0046] At this time, the operator turns the adjusting screw 11 to bring the two clamping blocks 8 closer to each other. The arc groove 9 clamps and fixes the cable insulation sleeve 1. Then the operator rotates the threaded sleeve 15 to squeeze and shrink the contraction end of the fixed sleeve 3 to further clamp the cable insulation sleeve 1. It should be noted that the operator can insert the clamping block 17 and the rubber block 18 into the groove 16 to adjust the clamping force of the contraction end.

[0047] At this point, the operator needs to twist the connecting sleeve 4 again so that the fixing sleeves 3 on both sides can get closer together. At this time, the fixing sleeve 3 can bring the cable insulation sleeve 1 closer together. The closer distance here is small, mainly to tighten it and ensure that the connection of the core 2 will not fall off or break due to external pulling force.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
