Description

Technical Field

[0001] This utility model relates to the field of power system connection technology, and in particular to a high-reliability cable connection structure. Background Technology

[0002] A high-reliability cable connection structure is typically designed to ensure the stability, durability, and electrical performance of the cable connection.

[0003] Existing technologies, such as the cable connection structure disclosed in CN215497137U, enhance the current-carrying capacity of the connection by using a connecting sleeve made of the same material as the metal wire core, resulting in low transmission loss. A fixing component is then fitted over the connecting sleeve to ensure a tight, seamless fit between the sleeve and the metal wire core, creating a robust connection that is not easily loosened and effectively guarantees the safety of power transmission. However, the following problems exist in its use:

[0004] The above technology connects two different cables using a fixing sleeve and a connecting sleeve. However, using only the fixing sleeve to fix the cables can easily cause the connection between the two cables to come loose. Furthermore, relying solely on the contact between the ends of the two cables makes it difficult to guarantee power transmission between them, and it cannot provide a highly reliable connection between the two cables. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology cannot provide a highly reliable connection between two cables, and to propose a highly reliable cable connection structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-reliability cable connection structure includes a fixed cylinder, with limiting cylinders for placing cables sleeved on both sides of the fixed cylinder. Two symmetrically distributed second fixing seats are fixedly installed on the outer walls of the two limiting cylinders. Fixing bolts are provided in the second fixing seats. Threaded holes are opened on the outer walls of the ends of the two limiting cylinders, and threaded sleeves for fixing the cables inside the limiting cylinders are sleeved on the outer walls of the two limiting cylinders.

[0008] Preferably, the fixed cylinder has two first through slots at both ends, and two second through slots connected to the first through slots are also provided inside the fixed cylinder. A third through slot is provided between the two second through slots, with both ends connected to the two second through slots.

[0009] Preferably, the fixed cylinder has two symmetrically arranged bolt holes, and the bottom of the bolt holes has a sliding groove. The upper and lower ends of the sliding groove are connected to the bolt holes and the third through groove, respectively. An adjusting bolt is threaded into the bolt hole, and the bottom end of the adjusting bolt is located in the sliding groove. A limit block is slidably arranged in the sliding groove, and the upper end of the limit block is rotatably connected to the bottom end of the adjusting bolt.

[0010] Preferably, a guide cylinder is fixedly installed at the end of the limiting cylinder, and the outer wall of the guide cylinder is in contact with the first through groove. A limiting ring is fixedly installed inside the limiting cylinder, and four limiting rods are provided on the left side of the limiting ring and fixedly installed on the inner wall of the limiting cylinder.

[0011] Preferably, a guide plate is slidably disposed inside the limiting cylinder, the guide plate has several placement holes for placing cable wires, and the outer wall of the guide plate has four equally spaced grooves, and the limiting rod is slidably disposed in the grooves of the guide plate.

[0012] Preferably, the outer wall of the limiting cylinder has four equally spaced deformation grooves, a conical block is fixedly installed at the end of the limiting cylinder, a conical limiting block is fixedly installed inside the threaded sleeve, and two first fixed seats are fixedly installed on the outer wall of the fixed cylinder, which are respectively arranged parallel to the second fixed seat.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention uses a conical limiting block to compress a conical block, thereby fixing the cable. The limiting block then compresses the cable wires within a sliding groove, ensuring stable power transmission between the cables. The first and second fixing seats are fixed with fixing bolts, ensuring the overall robustness between the fixing cylinder and the limiting cylinder, facilitating a highly reliable connection between the two cables.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A high-reliability cable connection structure includes a fixed cylinder 1, with limiting cylinders 10 for placing cables on both sides of the fixed cylinder 1. Two symmetrically distributed second fixing seats 11 are fixedly installed on the outer walls of the two limiting cylinders 10. Fixing bolts 12 are provided in the second fixing seats 11. Threaded holes 17 are opened on the outer walls of the ends of the two limiting cylinders 10, and threaded sleeves 20 for fixing the cables inside the limiting cylinders 10 are sleeved on the outer walls of the two limiting cylinders 10.

[0022] The fixed cylinder 1 has two first through grooves 2 at both ends, and two second through grooves 3 connected to the first through grooves 2 are also provided inside the fixed cylinder 1. A third through groove 4 is provided between the two second through grooves 3, with both ends connected to the two second through grooves 3.

[0023] The fixed cylinder 1 has two symmetrically arranged bolt holes 5. The bottom of the bolt hole 5 has a sliding groove 6, and the upper and lower ends of the sliding groove 6 are connected to the bolt hole 5 and the third through groove 4, respectively. An adjusting bolt 7 is threaded in the bolt hole 5, and the bottom end of the adjusting bolt 7 is set in the sliding groove 6. A limit block 8 is slidably arranged in the sliding groove 6, and the upper end of the limit block 8 is rotatably connected to the bottom end of the adjusting bolt 7.

[0024] A guide cylinder 13 is fixedly installed at the end of the limiting cylinder 10, and the outer wall of the guide cylinder 13 is in contact with the first through groove 2. A limiting ring 14 is fixedly installed inside the limiting cylinder 10, and four limiting rods 15 are provided on the left side of the limiting ring 14 and are fixedly installed on the inner wall of the limiting cylinder 10.

[0025] A guide plate 16 is slidably disposed inside the limiting cylinder 10. The guide plate 16 has several placement holes for placing cable wires, and four equally spaced grooves are formed on the outer wall of the guide plate 16. The limiting rod 15 is slidably disposed in the grooves of the guide plate 16 to facilitate limiting the guide plate 16. The limiting ring 14 limits the guide plate 16 to prevent it from sliding out of the limiting cylinder 10.

[0026] The outer wall of the limiting cylinder 10 is provided with four equally spaced deformation grooves 18. When the conical block 19 moves toward the cable through the deformation grooves 18, the limiting cylinder 10 is prevented from deforming. The conical block 19 is fixedly installed at the end of the limiting cylinder 10. The conical limiting block 21 is fixedly installed inside the threaded sleeve 20. Two first fixing seats 9 are fixedly installed on the outer wall of the fixing cylinder 1, which are respectively arranged parallel to the second fixing seat 11.

[0027] The functional principle of this utility model can be explained through the following operation methods:

[0028] In use, the two cable ends are passed through the threaded sleeve 20 and the limiting sleeve 10 in sequence. The insulation sleeve at the cable end is cut open, allowing the cable wire to pass through the guide plate 16 and extend into the third through groove 4 in the fixed sleeve 1. By turning the threaded sleeve 20, the threaded sleeve 20 rotates in the threaded hole 17 and moves laterally towards the guide plate 16, causing the conical limiting block 21 to press against the conical block 19, and causing the inner wall of the conical block 19 to press against the cable, thus fixing the cable.

[0029] Secondly, by turning the adjusting bolt 7, the adjusting bolt 7 rotates in the bolt hole 5 and pushes the limiting block 8 downward, causing the limiting block 8 to move in the sliding groove 6 towards the cable wire, squeezing the cable wire and ensuring the stability of power transmission between the two cables. Then, by turning the fixing bolt 12, the fixing bolt 12 connects the first fixing seat 9 and the second fixing seat 11, ensuring the firmness between the fixing cylinder 1 and the limiting cylinder 10 and preventing the cable from breaking at the middle connection point.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
