[0001] This invention belongs to the field of cable connection technology, specifically a cable connection device, connection method, and cable. Background Technology

[0002] Cable connectors are key components in cable systems, primarily used to establish electrical connections between cables and ensure stable transmission of current or signals. They provide reliable physical support through mechanical fastening (such as threaded locking and plug-in designs) to prevent loosening or damage to the connection.

[0003] Cables often need to be connected in multiple segments. When the cable connector is threaded and locked, workers need to carry tools to tighten the cable connector and fix it in place, so that the multiple cable segments are firmly fixed together.

[0004] However, the above-mentioned technologies often have the following drawbacks: due to the long laying distance between multiple cable segments, workers need to carry tools and travel long distances to reach the connection point for tightening and fixing when installing cable connectors. This working method is not only time-consuming and labor-intensive, but also reduces construction efficiency. This problem is even more prominent in complex terrain or large-scale engineering sites, increasing the labor intensity and time cost of workers.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1: As Figures 1 to 3 As shown in the embodiment of the present invention, a cable connection device includes a cable body 1, a female connector 11, and a female connector 12. The female connector 11 is provided with a terminal 15, and the cable body 1 is connected to both the female connector 11 and the female connector 12. A set of connecting plates 14 are fixedly connected to the side wall of the female connector 12. A slot 16 is formed on the outer side wall of the connecting plate 14. A connecting sleeve 13 is fixedly connected to the outer side wall of the female connector 11. A circular groove is formed at one end of the connecting sleeve 13 near the female connector 12, and the connecting plate 14 can be inserted into the circular groove. A set of sliding grooves 17 are formed on the inner wall of the circular grooves. A locking block 18 is slidably connected to the inner wall of the sliding grooves 17. The bottom surface of the locking block 18 is inclined. The locking block 18 is engaged with the slot 16, and a first spring is fixedly connected between the top surface of the locking block 18 and the inner wall of the sliding groove 17.

[0033] When connecting cable bodies 1, this application allows for the insertion of the female connector 12 into the terminal 15, where the female connector 12 fits snugly against the female connector 11. During insertion, the connecting plate 14 enters the circular groove, pushing the inclined surface of the locking block 18 upwards. When the female connector 12 and female connector 11 are fully inserted, the position of the locking groove 16 corresponds to the locking block 18. At this point, the locking block 18 engages with the locking groove 16 under the push of the first spring, thus achieving the effect of quickly assembling the female connector 12 and female connector 11 and improving the convenience of connecting multiple cable bodies 1.

[0034] The connecting sleeve 13 has a circular groove corresponding to the slot 16. A magnetic ring 19 that magnetically attracts the block 18 is slidably connected in the circular groove. The block 18 is made of magnetic material. A connecting rod 20 is slidably connected to one end of the connecting sleeve 13 near the head 12. The end of the connecting rod 20 near the block 18 is fixedly connected to the magnetic ring 19. A second spring is fixedly connected between the side of the magnetic ring 19 near the connecting rod 20 and the inner wall of the circular groove.

[0035] When it is necessary to disassemble the female head 12 and the female head 11, the connecting rod 20 can be pulled to move the magnetic ring 19, thereby moving the magnetic ring 19 to the back of the locking block 18. At this time, the locking block 18 will be attracted by the magnetic ring 19 and disengage from the locking slot 16. Then the female head 12 can be pulled to disengage from the female head 11, so as to complete the disassembly of the female head 12 and the female head 11.

[0036] The connecting sleeve 13 has a hollow groove 21 inside, and the outer wall of the connecting sleeve 13 is provided with an inlet pipe 22 that communicates with the hollow groove 21. An oil inlet check valve is provided inside the inlet pipe 22. The side wall of the female head 11 has a set of through connecting grooves 25, and the inner wall of the hollow groove 21 has a discharge groove 24 that communicates with the connecting grooves 25.

[0037] After the female connector 12 and the female connector 11 are connected, insulating oil can be injected through the inlet pipe 22, allowing the insulating oil to enter the hollow groove 21, then through the outlet groove 24 and the connecting groove 25, and finally into the female connector 11. At this time, the insulating oil will fill the interior of the female connector 11 and the female connector 12, effectively filling the gap at the connection between the female connector 12 and the terminal 15, removing air and moisture, preventing partial discharge and corona phenomena, significantly improving insulation strength, and also improving heat dissipation and reducing temperature rise. When the insulating oil is injected into the female connector 11, the air in the female connector 11 can be discharged from the joint between the female connector 12 and the female connector 11.

[0038] A push ring 23 is slidably connected inside the hollow groove 21. A third spring is fixedly connected between the end of the push ring 23 away from the female head 12 and the inner wall of the hollow groove 21. A sealing mechanism for sealing the discharge groove 24 is provided on the connecting sleeve 13. In this application, insulating oil can be injected into the hollow groove 21 from the liquid inlet pipe 22. At this time, the insulating oil will push the push ring 23 to move away from the locking block 18. After a certain amount of insulating oil is injected into the hollow groove 21, the injection is stopped. At this time, the insulating oil can be stored in the hollow groove 21. When the insulating oil is needed, the sealing mechanism can be removed from sealing the discharge groove 24. At this time, the push ring 23 will push the insulating oil under the thrust of the third spring, so that the insulating oil can be injected from the discharge groove 24 into the female head 11, thereby improving the convenience of using the insulating oil.

[0039] The sealing mechanism includes an elastic ring 29 fixedly connected to the inner wall of the circular groove. The elastic ring 29 has a hollow structure. A first moving groove 28 and a second moving groove 30 are provided inside the connecting sleeve 13. The first moving groove 28 and the second moving groove 30 are aligned. A sealing plate 26 is provided inside the first moving groove 28 and the second moving groove 30. The sealing plate 26 is slidably connected to the first moving groove 28. A through groove 27 is provided on the sealing plate 26. An air inlet 10 is provided on the inner wall of the first moving groove 28. An air outlet communicating with the air inlet 10 is provided on the side of the elastic ring 29 near the first moving groove 28. A fourth spring is fixedly connected between the side of the sealing plate 26 away from the elastic ring 29 and the inner wall of the second moving groove 30.

[0040] When the connecting plate 14 in this application is inserted into the circular groove, the connecting plate 14 will compress the elastic ring 29. At this time, the gas in the elastic ring 29 will enter the air inlet 10 from the air outlet, thereby pushing the sealing plate 26 in the first connecting plate 14, so that the through groove 27 on the sealing plate 26 moves to the discharge groove 24. At this time, the insulating oil in the hollow groove 21 can enter the female head 11. Under normal circumstances, the sealing plate 26 will be pushed by the fourth spring, so that the through groove 27 on the sealing plate 26 is located in the first connecting groove 25. At this time, the sealing plate 26 can seal the discharge groove 24.

[0041] Example 2: Figures 4 to 5 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: an annular fixing groove 32 is provided on the side of the female head 11 near the male head 12, and an elastic and hollow sealing ring 31 is fixedly connected to the inner wall of the fixing groove 32; when the female head 11 and the male head 12 are connected in this application, the port of the male head 12 will push and squeeze the sealing ring 31, so that the sealing ring 31 seals the connection between the male head 12 and the female head 11, so as to prevent moisture or other factors from affecting the use of insulating oil in the female head 11.

[0042] like Figure 6As shown, a cable includes the aforementioned cable connection device. The cable body 1 includes a filler layer 3, a shielding layer 4, an insulation layer 5, and a braided layer 6. The shielding layer 4 wraps around the conductor 2, and the filler layer 3 fills the space between the shielding layer 4 and the conductor 2. The shielding layer 4 is wrapped with the insulation layer 5, and a set of evenly distributed ring-shaped connection points 7 are provided outside the insulation layer 5. The connection points 7 are made of rubber material, and the braided layer 6 is connected to the connection points 7. In this application, the shielding layer 4 can reduce electromagnetic interference and improve signal transmission. The shielding layer 4 can be made of aluminum foil material, and the insulation layer 5 can be made of PVC material to prevent current leakage and protect the conductor 2 from external influences. The braided layer 6 can be made of aramid fiber material to protect the insulation layer 5 and improve its wear resistance. At the same time, the evenly distributed ring-shaped connection points 7 can firmly fix the braided layer 6 to the insulation layer 5.

[0043] The outer wall of the braided layer 6 is wrapped with an armor layer 9, which can be composed of multiple layers of steel strips. The armor layer 9 is provided with annularly distributed steel wires 8. In this application, the armor layer 9 can improve the mechanical strength of the cable and prevent damage from external forces. At the same time, the multiple layers of steel strips in the armor layer 9 can be connected by steel wires 8 to further improve the mechanical strength of the armor layer 9.

[0044] like Figure 7 As shown, a cable connection method is used to connect the aforementioned cable, and the method includes the following steps:

[0045] S1: Insulating oil is injected into the hollow groove 21 through the liquid inlet pipe 22. The insulating oil entering the hollow groove 21 will push the push ring 23 to move. After a certain amount of insulating oil is injected into the hollow groove 21, the injection is stopped and the insulating oil is stored in the hollow groove 21.

[0046] S2: Inspect the female connector 12 and female connector 11 to rule out any faults, and then plug the female connector 12 and female connector 11 into the terminal 15 so that the female connector 12 is inserted into the terminal 15. At this time, the female connector 12 will fit tightly with the female connector 11.

[0047] S3: During the insertion process, the connecting plate 14 will also enter the circular groove. During the entry process, it will push the inclined surface of the locking block 18, causing the locking block 18 to move upward. Then, when the male head 12 and the female head 11 are inserted, the position of the locking groove 16 will correspond to the locking block 18. At this time, the locking block 18 will engage with the locking groove 16 under the push of the first spring.

[0048] S4: During the insertion of the connecting plate 14, the through hole on the sealing plate 26 is moved to the discharge groove 24. At this time, the insulating oil can be pushed by the push ring 23, so that the discharge groove 24 enters into the female head 11, and the insulating oil effectively fills the gap at the connection between the female head 12 and the terminal 15.

[0049] Working principle: By inserting the female connector 12 into the terminal 15, the female connector 12 fits tightly against the female connector 11. During insertion, the connecting plate 14 also enters the circular groove, pushing the inclined surface of the locking block 18 upwards. When the female connector 12 and female connector 11 are fully inserted, the position of the slot 16 corresponds to the locking block 18. At this point, the locking block 18, pushed by the first spring, engages with the slot 16, thereby achieving... This invention achieves the effect of quickly assembling the female connector 12 and the female connector 11, improving the convenience of connecting multiple cable body segments 1. When it is necessary to disassemble the female connector 12 and the female connector 11, the connecting rod 20 can be pulled to move the magnetic ring 19, thereby moving the magnetic ring 19 to the back of the locking block 18. At this time, the locking block 18 will be attracted by the magnetic ring 19 and disengage from the locking slot 16. Then, the female connector 12 can be pulled to disengage from the female connector 11, thus completing the disassembly of the female connector 12 and the female connector 11.

[0050] After the female connector 12 and female connector 11 are connected, insulating oil can be injected through the inlet pipe 22, allowing the insulating oil to enter the hollow groove 21, then pass through the outlet groove 24 and the connecting groove 25, and finally enter the female connector 11. At this time, the insulating oil will fill the interior of the female connector 11 and the female connector 12, effectively filling the gap at the connection between the female connector 12 and the terminal 15, eliminating air and moisture, preventing partial discharge and corona phenomena, significantly improving insulation strength, and also improving heat dissipation and reducing temperature rise. When the insulating oil is injected into the female connector 11, the air inside the female connector 11 can be discharged from the contact point between the female connector 12 and the female connector 11. In this application, insulating oil can be injected into the hollow groove 21 through the inlet pipe 22 first. At this time, the insulating oil will push the push ring 23 to move away from the locking block 18. After a certain amount of insulating oil is injected into the hollow groove 21, the injection is stopped. The insulating oil can be stored in the hollow groove 21. When the insulating oil is needed, the sealing mechanism can stop sealing the discharge groove 24. At this time, the push ring 23 will push the insulating oil under the force of the third spring, so that the insulating oil can be injected into the female head 11 from the discharge groove 24, thereby improving the convenience of using the insulating oil. When the connecting plate 14 in this application is inserted into the circular groove, the connecting plate 14 will squeeze the elastic ring 29. At this time, the gas in the elastic ring 29 will enter the air inlet 10 from the air outlet, thereby pushing the sealing plate 26 in the first connecting plate 14, so that the through groove 27 on the sealing plate 26 moves to the discharge groove 24. At this time, the insulating oil in the hollow groove 21 can enter the female head 11. Under normal circumstances, the sealing plate 26 will be pushed by the fourth spring, so that the through groove 27 on the sealing plate 26 is located in the first connecting groove 25. At this time, the sealing plate 26 can seal the discharge groove 24.
