Description

Technical Field

[0001] This invention relates to the field of power line technology, and in particular to a reinforced cable joint. Background Technology

[0002] Cables, as a crucial medium for transmitting electrical energy and signals and realizing electromagnetic energy conversion, play an indispensable role in modern power systems and communication networks. They typically consist of conductors, insulation layers, and sheaths, ensuring efficient transmission of current or signals and protecting the cable from external environmental influences. Cable joints are important components in cable lines, primarily used to connect two or more cables to achieve continuous power or signal transmission. Because cable joints require manual methods to establish conductivity between conductors and necessitate re-insulation and sheathing, they exhibit structural discontinuity compared to the cable body, becoming a weak point in the entire cable line.

[0003] In existing technologies, cable joints are prone to problems such as poor contact and insulation defects due to structural discontinuities, resulting in a high failure rate. Especially during cable laying, equipment operation may pull the cable, subjecting the joint to additional stress. After backfilling, changes in ambient humidity can also adversely affect the joint. Furthermore, traditional cable joints lack effective support and sealing measures, making it difficult to cope with complex changes in the external environment. Specifically, current joint designs cannot ensure a tight fit between the two ends of the cable, nor can they effectively isolate the connection area from the external environment. This makes the joint susceptible to moisture erosion during long-term use, accelerating the deterioration process and increasing maintenance costs and safety risks. Therefore, we propose a reinforced cable joint to overcome the above-mentioned defects. Summary of the Invention

[0009] Furthermore, it is particularly preferred that the mounting cylinder is provided with a cable management mechanism on the side near the cable connection point. The cable management mechanism is used to organize the multiple core wires at the cable connection point. The cable management mechanism includes a fixing ring and a partition plate. The fixing ring is fixedly connected to the opening of the mounting cylinder on the connection side. The partition plate has wire holes adapted to the number of cable core wires. The partition plate is used to separate and support the cable core wires.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0029] A reinforced cable connector, such as Figures 1-5As shown, the device includes a connecting sleeve 1, which is an existing connector used to connect the core wires of the stripped ends of two cables 100; it also includes a fixing connector 2 disposed at the mating ends of the cables 100 to be connected. The fixing connector 2 includes a mounting cylinder 21, a locking plate 23, and a clamping block 24. The mounting cylinder 21 is slidably sleeved on the outer sheath of the mating ends of the two cables 100. The mounting cylinder 21 is a cylinder with openings on both sides. Multiple mounting grooves 22 are circumferentially provided on the mounting cylinder 21. The locking plate 23 is rotatably connected to the mounting grooves 22 of the mounting cylinder 21. The locking plate 23 can rotatably cover the corresponding mounting groove 22. The locking plate 23 protrudes inward and is fixedly installed with the clamping block 24. The clamping block 24 is made of elastic material and has anti-slip texture on its inner side. The clamping block 24 is used to securely limit the mounting cylinder 21 on the outer sheath of the cable 100. The mounting cylinder 21 is provided with fasteners 3 for locking and fixing the locking plate 23. The fixing connectors on both sides are... A support mechanism 4 is provided between the two ends of the cable 100. The support mechanism 4 is used to support the cable 100 connected on both sides, thereby improving the overall structural strength of the cable 100. When connecting the cable 100 at both ends, the fixing connector 2 is first slidably installed on the connecting end of the cable 100 at both ends. When the mounting cylinder 21 inside the fixing connector 2 slides into the appropriate position of the cable 100, the multiple locking plates 23 around the mounting cylinder 21 are pressed inward, so that the pressing blocks 24 on the locking plates 23 can press inward onto the outer sheath of the cable 100. Then, the locking plates 23 are fixedly fixed by the fasteners 3, so that the mounting cylinder 21 can be stably installed on the cable 100. Then, the core wires of the cable 100 at both ends are connected by the connecting sleeve 1. Finally, the support mechanism 4 is activated to stably support the cable 100 at both ends, improving the connection stability and structural strength of the cable 100. At the same time, it is convenient to seal the connection end of the cable 100 in the future.

[0030] like Figure 3 and Figure 4 As shown, the fastener 3 consists of a bolt 32 and a nut 33. The end of the locking plate 23 away from the rotating shaft 44 has a through groove 31. The cylinder wall of the mounting cylinder 21 has an opening that matches the through groove 31 of the locking plate 23. The bolt 32 is located in the through groove 31 of the locking plate 23. The nut 33 is screwed onto the threaded bolt 32. After the bolt 32 is passed through the through groove 31 of the mounting cylinder 21 and the locking plate 23 in sequence, it is screwed into the nut 33, so that the locking plate 23 can be stably covered in the mounting groove 22 of the mounting cylinder 21. This ensures that the clamping blocks 24 of each locking plate 23 can stably press and lock the cable 100, improving the stability of the fixed joint 2 fixedly installed on the outer sheath of the cable 100.

[0031] like Figure 1 , Figure 2 and Figure 5As shown, the support mechanism 4 includes a mounting seat 41 fixedly connected to the outer wall of the mounting cylinder 21. A snap-fit ​​seat 42 is also fixedly connected to the outer wall of the mounting cylinder 21. Multiple sets of mounting seats 41 and snap-fit ​​seats 42 are provided on the outer wall of the mounting cylinder 21 and are alternately distributed. A support plate 43 is rotatably connected to the mounting seat 41. The support plate 43 on one end of the mounting seat 41 can be rotatably snapped onto the snap-fit ​​seat 42 at the other end. A rotating shaft 44 is fixedly connected inside each snap-fit ​​seat 42. A snap-fit ​​seat 42 is symmetrically rotatably connected to a snap-fit ​​block 45 through the rotating shaft 44. A torsion spring 46 is provided between the rotating shaft 44 and the snap-fit ​​block 45. A slot for matching the snap-fit ​​block 45 is symmetrically opened on the side wall of the support plate 43. When the support plate 43 rotates and closes into the corresponding snap-fit ​​seat 42, the snap-fit ​​block 45 can lock the support plate 43 under the action of the torsion spring 46, so that the support plate 43 can be stably supported between the two ends of the mounting cylinder 21.

[0032] like Figure 2 and Figure 5 As shown, the middle part of the support plate 43 has an upwardly convex arched structure. The support plate 43 can better distribute the vertical load to the support points on both sides, and improve the structural stability of the support plate 43 at the joint of the cable 100.

[0033] First, insert the mounting sleeves 21 of the two fixed connectors 2 onto the outer sheaths of the two cables 100 to be connected from the mating ends, and push them along the surface of the outer sheaths to the predetermined positions. Then, manually press each locking plate 23 distributed circumferentially on the mounting sleeve 21, causing the locking plate 23 to rotate inward around the pivot 44 on the mounting sleeve 21 until it is completely covered in the corresponding mounting groove 22. During the closing process of the locking plate 23, the pressing block 24 on the inner side of the locking plate 23 moves inward synchronously, and the inner side of the pressing block 24 is tightly pressed against the cable due to elastic deformation. A stable circumferential constraint is formed on the surface of the outer sheath of the cable 100. Next, fasteners 3 are used to securely lock each covered locking plate 23, i.e., bolts 32 passing through specific openings on the mounting cylinder 21 and through slots 31 at the ends of the locking plates 23, and nuts 33 are tightened at their tails. This ensures that the clamping blocks 24 continuously apply sufficient clamping force, thereby stably and reliably fixing the entire fixing joint 2 to the outer sheath of the cable 100. After both fixing joints 2 are securely installed, standard connecting sleeves 1 can be used to connect the two cables using conventional methods. After the exposed core wires of the stripped cable 100 are securely connected, and the core wires are connected through the connecting sleeve 1, the support mechanism 4 is deployed to enhance the overall rigidity of the joint. The support plate 43, rotatably connected inside each mounting seat 41 on the outer wall of one side of the mounting cylinder 21, is rotated upwards and across the joint area around its connection point with the mounting seat 41 until the free end of the support plate 43 precisely falls into and covers the corresponding snap-fit ​​seat 42 on the outer wall of the opposite side of the mounting cylinder 21. During the process of the support plate 43 covering the snap-fit ​​seat 42, the support plate 4... 3. Overcoming the elastic force of the torsion spring 46, the locking block 45 is pressed outward to rotate until the support plate 43 is fully embedded in the locking seat 42. Then, driven by the torsion spring 46, it is reset and rotated. The end of the locking block 45 is quickly and reliably embedded in the pre-opened slot on the side wall of the support plate 43, realizing automatic locking of the support plate 43. At this time, the arched support plate 43 is firmly connected between the two mounting cylinders 21, effectively dispersing the vertical load applied near the cable connection point to the fixed joints 2 on both sides, thereby significantly improving the joint's ability to resist bending and deformation.

[0034] like Figure 3 and Figure 6 As shown, a cable management mechanism 5 is provided on the side of the mounting cylinder 21 near the cable 100 connection point. The cable management mechanism 5 is used to organize the multiple core wires at the connection point of the cable 100. The cable management mechanism 5 includes a fixing ring 51 and a partition plate 52. The fixing ring 51 is fixedly connected to the opening of the mounting cylinder 21 on the connection side. The partition plate 52 has wire holes adapted to the number of core wires of the cable 100. The partition plate 52 is used to separate and support the core wires of the cable 100, so that the core wires of the two ends of the cable 100 can be neatly connected, reducing the risk of misalignment.

[0035] like Figure 6 and Figure 7As shown, the inner side of the fixing ring 51 is symmetrically provided with mounting grooves 511. The partition plate 52 is slidably snapped into the fixing ring 51 through the mounting grooves 511. The two ends of the partition plate 52 are provided with locking holes. The fixing ring 51 is provided with a locking element 6 for locking the partition plate 52. The partition plate 52 can be flexibly replaced according to the number of core wires of the cable 100, thereby improving the applicability of the cable joint.

[0036] like Figure 6 and Figure 7 As shown, the fastener 6 includes a sleeve rod 61, a locking rod 62, and a spring 63. The upper and lower parts of the fixing ring 51 are symmetrically fixedly connected to the sleeve rod 61. The locking rod 62 for locking the hole of the partition plate 52 is slidably connected inside the sleeve rod 61. A spring 63 is provided between the sleeve rod 61 and the locking rod 62. When the partition plate 52 is rotated into the correct position of the fixing ring 51 through the mounting groove 511, the locking rod 62 inside the sleeve rod 61 will be locked into the corresponding locking hole of the partition plate 52 under the action of the spring 63.

[0037] like Figure 1 and Figure 8 As shown, a protective shell 7 is provided around the cable 100. The protective shell 7 is designed as two symmetrical halves that are hinged together. The protective shell 7 can be rotated and combined to cover the connectors of the cable 100 at both ends. A screw seat 71 is fixedly provided on the side of the protective shell 7 away from the hinge. The protective shell 7 is fixed by screwing screws into the screw seat 71.

[0038] like Figure 8 As shown, the protective housing 7 has an annular isolation frame 8 inside, and a cavity is provided between the isolation frame 8 and the protective housing 7. An injection valve 81 is installed on the outer wall of the protective housing 7. The injection valve 81 is used to inject potting compound into the cavity between the isolation frame 8 and the protective housing 7. When the protective housing 7 tightly covers the joint of the cable 100 at both ends, the cavity between the isolation frame 8 and the protective housing 7 is filled with potting compound through the injection valve 81. After the potting compound solidifies, it can further improve the sealing performance of the protective housing 7, prevent moisture intrusion, and provide additional mechanical support for the cable 100 joint.

[0039] like Figure 1-8 As shown, both the protective shell 7 and the isolation frame 8 have grooves for adapting to the cable 100. Both the protective shell 7 and the isolation frame 8 have sealing gaskets 9 in their grooves. The sealing gaskets 9 are used to improve the sealing performance of the protective shell 7 and the isolation frame 8 at the point where they contact the cable 100.

[0040] After completing the installation of the fixed connector 2, before connecting the core wires of the cable 100, the cable management mechanism 5 can be used to sort and position the multiple core wires that are scattered at the joint end of the cable 100. During operation, firstly, according to the number of cable core wires, select a partition plate 52 with a corresponding number of wire holes. Align the specific edge of the selected partition plate 52 with the symmetrically opened mounting grooves 511 on the inner side of the fixing ring 51, and then slide and push it in along the direction of the groove, so that the partition plate 52 is initially locked into the fixing ring 51. When the partition plate 52 slides and rotates to the preset correct position within the fixing ring 51, Under the action of spring 63, the latch 62 inside the buckle 6 pops out from the sleeve 61 and precisely engages with the corresponding latch holes at both ends of the partition plate 52, thus firmly locking the partition plate 52 within the fixing ring 51. At this time, the stripped core wires of the two cables 100 at their joint ends pass through the corresponding wire holes on their respective side partition plates 52. The wire holes of the partition plate 52 effectively separate the core wires that might have overlapped and tangled, guiding each core wire to arrange independently, neatly, and parallelly and extend to the joint area. Thus, when the connecting sleeve 1 is used to connect the core wires on both sides, each core wire... The wires are precisely aligned, reducing the risk of misalignment, crossing, or twisting during core wire splicing, ensuring the accuracy and regularity of the core wire connection, and laying a good foundation for the final connection quality of the cable 100. Finally, the two halves of the protective shell 7, which are connected by hinges, are joined and fastened to the outside of the connected and reinforced cable 100 joint, and screws are screwed into the screw seats 71 on the edge of the protective shell 7 for tightening, ensuring that the grooves on the protective shell 7 and its internal isolation frame 8 fit tightly against the cable outer sheath. The sealing gasket 9 in the groove provides an initial seal, and then the protective shell 7... The injection valve 81 installed on the outer wall continuously injects liquid potting compound into the annular cavity formed between the inner wall of the protective shell 7 and the outer wall of the isolation frame 8. Under pressure, the potting compound completely fills every gap in the entire cavity. After the potting compound has fully cured, with the synergistic effect of the sealing gasket 9, not only is a high degree of sealing achieved in the joint area, effectively preventing the intrusion of the external environment (especially moisture), but the solidified potting compound itself also provides additional, evenly distributed mechanical support and protection for the entire cable 100 joint structure, thereby improving the reliability and safety of the cable joint.
