Description

A cable structure that is easy to inspect and maintain. Technical Field

[0001] This utility model relates to the field of power accessories, and in particular to a cable structure. Background Technology

[0002] Currently, when splicing two cables, the cable cores are usually first wound or welded together, and then insulating tape is used to wrap the splice joint and the insulation of both cables. To effectively protect the splice joint, multiple layers of insulating tape are often required, and the tape needs to be sufficiently wide across the insulation. This results in a large amount of tape being wrapped, making the process of removing the tape cumbersome and severely hindering the convenience and efficiency of cable splice maintenance. Furthermore, the removed insulating tape is not easily reused and generally needs to be rewrapped, increasing maintenance costs. Therefore, it is essential to design a cable structure that facilitates maintenance and addresses these technical problems. Summary of the Invention

[0003] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a cable structure that is easy to maintain. This cable structure has the advantages of simple and convenient maintenance, high maintenance efficiency, low maintenance cost, high reliability, and strong applicability.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A cable structure for easy maintenance is characterized by comprising two cables, an insulating sleeve, and at least one locking assembly. The cores of the two cables are butted together. The insulating sleeve is fitted onto the butt joint of the two cables, and both ends of the insulating sleeve are slidably and sealingly fitted onto the insulation of the two cables. The locking assembly includes an insulating collar and at least one locking screw. The insulating collar is tightly fitted onto the core, and the locking screw is screwed onto the insulating sleeve, and the locking screw can be tightly pressed against the insulating collar.

[0006] Preferably, positioning ring grooves are respectively opened on the inner walls of both ends of the insulating sleeve, and sealing rubber rings are respectively embedded in the two positioning ring grooves, and the two sealing rubber rings are respectively sealed and fitted onto the insulation of the two cables.

[0007] Preferably, there are two locking components, and the insulating collars of the two locking components are tightly fitted onto the cores of the two cables, with only one locking screw on each locking component.

[0008] Preferably, the outer wall of the insulating sleeve has a threaded hole extending to its inner wall, with the inner opening of the threaded hole facing the outer wall of the insulating sleeve. The locking screw is a set screw, and the locking screw is screwed into the threaded hole.

[0009] Preferably, the insulating collar is a soft insulating collar, and the middle part of the outer wall of the insulating collar is tightly attached to the inner opening of the threaded hole.

[0010] Preferably, the axial width of the insulating collar is more than three times larger than the outer diameter of the threaded hole.

[0011] The beneficial effects of this utility model are as follows: In this cable structure, an insulating sleeve is used to fit the joint of two cables, and the two ends of the insulating sleeve are slidably and sealingly fitted onto the insulation of the two cables. This not only quickly and effectively shields and seals the joint of the two cables, but also allows the joint to be quickly exposed by sliding the insulating sleeve. A locking assembly is provided, including an insulating collar and at least one locking screw. The insulating collar is tightly fitted onto the wire core, and the locking screw is screwed onto the insulating sleeve and pressed tightly against the insulating collar. Tightening the locking screw locks the insulating sleeve, thus ensuring high reliability of the cable structure; loosening the locking screw allows the insulating sleeve to slide. This makes the inspection and maintenance of the cable joint very simple and convenient, greatly improving maintenance efficiency. Furthermore, both the insulating sleeve and the locking assembly can be reused, reducing maintenance costs. Therefore, this cable structure has very strong applicability. Attached Figure Description

[0012] Figure 1 is a schematic diagram of the cable structure in this utility model. Detailed Implementation

[0013] As shown in Figure 1, the present invention provides a cable structure that is easy to maintain, comprising two cables 1, an insulating sleeve 2, and at least one locking component 3. The cores 11 of the two cables 1 are joined together. The insulating sleeve 2 is fitted onto the joint of the two cables 1, and both ends of the insulating sleeve 2 are slidably and sealingly fitted onto the insulation sheaths 12 of the two cables 1. The locking component 3 includes an insulating collar 31 and at least one locking screw 32. The insulating collar 31 is tightly fitted onto the core 11, and the locking screw 32 is screwed onto the insulating sleeve 2, and the locking screw 32 is pressed tightly against the insulating collar 31.

[0014] In this cable structure, an insulating sleeve 2 is fitted over the joint of two cables 1, and both ends of the insulating sleeve 2 are slidably and sealingly fitted onto the insulation sheaths 12 of the two cables 1. This not only quickly and effectively shields and seals the joint of the two cables 1, but also allows the joint of the two cables 1 to be quickly exposed by sliding the insulating sleeve 2. A locking assembly 3 is provided, including an insulating collar 31 and at least one locking screw 32. The insulating collar 31 is tightly fitted onto the core 11, and the locking screw 32 is screwed onto the insulating sleeve 2, and the locking screw 32 can be tightly pressed against the insulating collar 31. Tightening the locking screw 32 locks the insulating sleeve 2 in place, thus giving the cable structure high reliability; while loosening the locking screw 32 allows the insulating sleeve 2 to slide. This makes the maintenance of the cable joint very simple and convenient, greatly improving maintenance efficiency. Moreover, both the insulating sleeve 2 and the locking assembly 3 can be reused, which reduces maintenance costs. Therefore, this cable structure has very strong applicability.

[0015] As shown in Figure 1, positioning ring grooves 21 are respectively formed on the inner walls of both ends of the insulating sleeve 2. Sealing rings 22 are embedded in each of the two positioning ring grooves 21, and the two sealing rings 22 are respectively fitted onto the insulation sheaths 12 of the two cables 1. The sealing rings 22 effectively improve the sealing performance of the insulating sleeve 2 when fitted onto the insulation sheaths 12; the positioning ring grooves 21 provide stable and reliable positioning for the sealing rings 22, preventing them from shifting or detaching during the fitting of the insulating sleeve 2, thus ensuring that the sealing rings 22 can stably perform their sealing function; this helps to further improve the reliability and applicability of the cable structure.

[0016] To further improve the stability and reliability of the installation and positioning of the sealing ring 22, the sealing ring 22 can be glued and fixed in the positioning ring groove 21. This will prevent the sealing ring 22 from shifting or falling off when the sliding insulating sleeve 2 is in motion, thus avoiding any impact on the sealing performance.

[0017] As shown in Figure 1, there are two locking components 3. The insulating collars 31 of the two locking components 3 are tightly fitted onto the cores 11 of the two cables 1, and each locking component 3 has only one locking screw 32. This meets the requirement of bidirectional locking, which not only improves the stability of the installation and positioning of the insulating sleeve 2, but also facilitates the fitting and disassembly of the insulating sleeve 2, while still ensuring convenient maintenance.

[0018] As shown in Figure 1, the outer wall of the insulating sleeve 2 has a threaded hole 23 extending to its inner wall, with the inner opening of the threaded hole 23 facing the outer wall of the insulating collar 31. The locking screw 32 is a set screw, which is screwed into the threaded hole 23. Tightening the locking screw 32 allows its inner end to press firmly against the outer wall of the insulating collar 31. This not only facilitates convenient and stable installation and positioning of the locking screw 32, but also ensures that the locking screw 32 accurately acts on the insulating collar 31, thereby further improving the convenience of locking and unlocking, as well as the reliability of locking, and ultimately enhancing the reliability and applicability of the cable structure.

[0019] The insulating collar 31 is glued to the wire core 11, which achieves stable positioning of the insulating collar 31. This allows the insulating collar 31 to better restrict the locking screw 32 when it is pressed tightly against the insulating collar 31, thereby helping to further improve the reliability and applicability of the cable structure.

[0020] As shown in Figure 1, the insulating collar 31 is a soft insulating collar, and the middle of the outer wall of the insulating collar 31 is tightly fitted against the inner opening of the threaded hole 23. This allows the insulating collar 31 to seal the threaded hole 23, preventing moisture and dust from entering the insulating sleeve 2 from the threaded hole 23. This avoids the adverse effects of moisture and dust on the mating joint of the wire cores 11, thereby further improving the reliability and applicability of the cable structure.

[0021] As shown in Figure 1, the axial width of the insulating collar 31 is more than three times larger than the outer diameter of the threaded hole 23. This not only meets the requirement of the locking screw 32 pressing the insulating collar 31 to achieve locking, but also allows the insulating collar 31 to better separate the threaded hole 23 from the connection point of the wire core 11, thereby further improving the safety of the connection.

[0022] The insulating sleeve 2 is made of rigid insulating plastic, the insulating collar 31 is made of soft insulating plastic, and the locking screw 32 is a plastic screw. This provides good insulation, thereby improving the safety of cable connections.
