DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] See also Figure 1-2 9. A wire core 11 is arranged inside the aluminum alloy cable 1. The wire core 11 extends from one end of the aluminum alloy cable 1, and a convex ring 12 is arranged at the end of the aluminum alloy cable 1 corresponding to the extending portion of the wire core 11. A liquid capsule 31 is arranged on the outer side of the aluminum alloy cable 1, and a push ring 3 and a mounting ring 32 are fixedly connected at both ends of the liquid capsule 31, and a protective sleeve 4 is arranged on the outer movable sleeve of the push ring 3.

[0048] The outer fixed sleeve of the terminal body 2 is provided with an insulating sleeve 21, one end of the insulating sleeve 21 is fixedly provided with a fixing ring 22, and a rotating ring 5 is rotatably provided on the fixing ring 22. By inserting the wire core 11 extending from the aluminum alloy cable 1 into the connector 20 on the terminal body 2, the connection between the aluminum alloy cable 1 and the terminal body 2 can be achieved.

[0049] Among them, the specific materials and principles of the aluminum alloy cable 1, the wire core 11, the terminal body 2 and the connector 20 are all existing technologies, so they are not elaborated in detail.

[0050] See also Figure 3-5The insulating sleeve 21 is fixedly mounted on the connector 20, and a plurality of limiting grooves 211 are provided on the insulating sleeve 21. The provision of the insulating sleeve 21 can improve the safety of the terminal body 2 when powered. A fixing ring 22 is fixedly mounted on one end of the insulating sleeve 21, and the fixing ring 22 is also adapted to be fixedly mounted on the connector 20.

[0051] A ring-shaped silicone pleated cavity 221 is provided on one side of the fixing ring 22, four clamping cavities 222 are provided on the outside of the fixing ring 22, and an external thread 223 is also provided on the outside of the fixing ring 22. The silicone pleated cavity 221 is adapted to the mounting piece 321 on the mounting ring 32; and the clamping cavities 222 are adapted to the elastic clamping piece 43 on the protective sleeve 4.

[0052] A rotating ring 5 is rotatably arranged on the fixed ring 22 , an inner thread groove 56 is provided on the inner wall of the rotating ring 5 corresponding to the fixed ring 22 , and the rotating ring 5 is sleeved on a side of the fixed ring 22 away from the clamping cavity 222 .

[0053] See also Figure 5-7 Four first fixing members 51 and two second fixing members 52 are fixedly arranged on the rotating ring 5, and the two second fixing members 52 are fixedly connected by a plurality of reinforcing rings 55. Through holes 53 are opened on the second fixing members 52 toward the auxiliary cavity 35 on the push ring 3, and adjustment columns 54 are movably arranged in the through holes 53.

[0054] A fixing plate 531 is fixedly arranged in each through hole 53, and a fixing plate cavity 541 is adapted to be opened on the adjusting column 54 corresponding to the fixing plate 531. The adaptation arrangement between the fixing plate 531 and the fixing plate cavity 541 can not only guide the adjusting column 54 when it moves, but also prevent the adjusting column 54 from falling off from the through hole 53.

[0055] See also Figure 8 , 12 -13, a liquid capsule 31 is sleeved on the outer side of the aluminum alloy cable 1, the middle part of the liquid capsule 31 is fixedly set on the convex ring 12, and a marking ring 311 is fixedly set on the outer side of the middle part of the liquid capsule 31, and the user can observe the position of the liquid capsule 31 through the marking ring 311. One end of the liquid capsule 31 is fixedly connected to the push ring 3, and the push ring 3 is sleeved on the outer side of the aluminum alloy cable 1 and is movable on the aluminum alloy cable 1. The other end of the liquid capsule 31 is connected to the mounting ring 32, and the mounting ring 32 is located on the outer side of the wire core 11 extending from the aluminum alloy cable 1. It is worth noting that only the middle part of the liquid capsule 31 is connected to the convex ring 12, and other parts are not connected to the aluminum alloy cable 1 or the wire core 11.

[0056] A protective sleeve 4 is movably arranged outside the push ring 3, and outer guide grooves 41 are provided on both sides of the protective sleeve 4, and outer guide members 33 are adapted to correspond to the outer guide grooves 41 on both sides of the push ring 3. Through the adaptation between the outer guide member 33 and the outer guide groove 41, the protective sleeve 4 can be guided and moved outside the push ring 3. It is worth noting that the protective sleeve 4 is made of transparent material.

[0057] See also Figure 9-11 , a mounting piece 321 is fixedly arranged on the mounting ring 32, and the user can insert the terminal body 2 and the insulating sleeve 21 into the liquid capsule 31 through the mounting ring 32, and then insert the mounting piece 321 into the silicone pleated cavity 221 on the fixing ring 22, and then the insulating sleeve 21 can be assembled in the liquid capsule 31. And the mounting ring 32 and the fixing ring 22 are correspondingly provided with matching positioning marks, so that when the insulating sleeve 21 is assembled in the liquid capsule 31, the limiting groove 211 on the insulating sleeve 21 can be matched and aligned with the elastic capsule 312 on the liquid capsule 31.

[0058] The interior of the liquid capsule 31 is sealed and filled with liquid. A plurality of elastic capsules 312 are adapted to be arranged on the inner wall of the liquid capsule 31 corresponding to the limiting groove 211, and the elastic capsule 312 is connected to the liquid capsule 31. When the user pushes the push ring 3 toward the marking ring 311, one side of the liquid capsule 31 can be squeezed so that the liquid in the liquid capsule 31 flows to the side close to the mounting ring 32. At this time, these liquids can squeeze the elastic capsule 312 outward, so that the elastic capsule 312 protrudes outward. Not only will the liquid capsule 31 located outside the insulating sleeve 21 squeeze the insulating sleeve, but the protruding elastic capsule 312 can be adapted to be filled and carded in the corresponding limiting groove 211, so that the liquid capsule 31 can be stably connected to the insulating sleeve 21, thereby realizing the connection between the wire core 11 and the terminal body 2. And when the push ring 3 does not squeeze the liquid capsule 31, the elastic capsule 312 can automatically reset by its own elasticity.

[0059] See also Fig. 9 , 12, the left and right sides of the aluminum alloy cable 1 are provided with inner guide grooves 13, and the upper and lower sides of the aluminum alloy cable 1 are provided with card slots 14. The left and right sides of the inner wall of the push ring 3 are adapted to the inner guide grooves 13 and are provided with inner guide members 36. Through the adaptation between the inner guide grooves 13 and the inner guide members 36, the push ring 3 can be guided and moved on the aluminum alloy cable 1. The upper and lower sides of the push ring 3 are provided with movable cavities 34, and movable clamps 341 are movably provided in the movable cavities 34. Through the adaptation between the movable clamps 341 and the card slots 14, the push ring 3 can be fixed on the aluminum alloy cable 1. It is worth noting that the inner walls of the inner guide grooves 13 and the card slots 14 are paved with plastic shaping plates to prevent the inner guide grooves 13 and the card slots 14 on the aluminum alloy cable 1 from deforming during use.

[0060] See also Figure 13-17 , spring chambers 343 are provided on both sides of the movable cavity 34, and spring mounting parts are fixedly provided on both sides of the movable clamping member 341 corresponding to the spring chamber 343. The spring mounting parts are all located in the spring chamber 343, and springs 344 are installed on the spring mounting parts, and the other ends of the springs 344 are connected to the inner wall of the spring chamber 343. By setting the springs 344 in the spring chamber 343, the movable clamping member 341 can be pushed into the inside of the push ring 3. In this way, when the movable cavity 34 is aligned with the card slot 14, the movable clamping member 341 can automatically move and be set into the card slot 14. Since the push ring 3 is sleeved on the aluminum alloy cable 1 and moved, and the bottom surface of the movable clamping member 341 is made of smooth material, when the movable cavity 34 is not aligned with the card slot 14, the movable clamping member 341 cannot be pushed out of the movable cavity 34 by the spring 344, so that the movable clamping member 341 will not affect the normal movement of the push ring 3.

[0061] A sub-cavity 35 is provided on one side of the push ring 3 located at the active cavity 34, and an adjusting member 351 is provided in the sub-cavity 35 to guide the movement through the guide column 353, and an adjusting groove 352 is provided on the adjusting member 351. The adjusting groove 352 is adapted to the adjusting column 54 on the second fixing member 52, and the inner wall of the adjusting groove 352 and the bottom of the adjusting column 54 are both made of magnetic materials that are adapted to attract each other. It is also worth noting that an adjusting cavity 42 is adapted to be provided on the protective sleeve 4 corresponding to the active cavity 34 and the sub-cavity 35, so that the adjusting column 54 can enter the sub-cavity 35 through the adjusting cavity 42.

[0062] A fixed rope column 342 is fixedly arranged in the movable cavity 34, and a vertical rope guide groove is opened in the fixed rope column 342. A first traction rope 345 is fixedly connected to the movable clamp 341, and the other end of the first traction rope 345 passes through the rope guide groove in the fixed rope column 342 and extends into the auxiliary cavity 35 to be connected with the adjustment member 351. Therefore, when the movable clamp 341 moves toward the middle of the push ring 3, the adjustment member 351 can be pulled by the first traction rope 345 and move in the direction of the movable cavity 34 in the auxiliary cavity 35; and when the adjustment member 351 moves in the reverse direction in the auxiliary cavity 35, the movable clamp 341 can be pulled by the first traction rope 345 and reset to the movable cavity 34.

[0063] See also Figure 5 , 18 -21, one end of the protective sleeve 4 is provided with four cavities, each of which is provided with an elastic clamp 43, and each of the elastic clamps 43 is adapted to the clamping cavity 222. A fixing seat 44 is fixedly provided on the outer side of the elastic clamp 43 on the protective sleeve 4, and an upper cavity 441 and a lower cavity 442 are provided in the fixing seat 44. A second traction rope 443 is provided on the top of the fixing seat 44, and the second traction rope 443 passes through the upper cavity 441 and the lower cavity 442 in sequence and is connected to the elastic clamp 43.

[0064] The first fixing members 51 are all fixedly arranged on the rotating ring 5. When the rotating ring 5 is locked on the fixing ring 22 and the elastic clamping member 43 is clamped in the clamping cavity 222, the first fixing members 51 are all in the upper cavity 441 and located on one side of the second traction rope 443. At this time, the user only needs to slightly rotate the rotating ring 5 to drive the first fixing member 51 to rotate through the rotating ring 5, so that the second traction rope 443 can be pulled out of the upper cavity 441 through the rotation of the first fixing member 51, so that the elastic clamping member 43 can be pulled out of the clamping cavity 222 through the second traction rope 443, and at this time, the clamping between all the elastic clamping members 43 and the clamping cavity 222 can be released synchronously.

[0065] The first fixing member 51 is fixedly provided with a first anti-dropping member 511 and a second anti-dropping member 512 facing the second traction rope 443. The first anti-dropping member 511 and the second anti-dropping member 512 can prevent the second traction rope 443 from falling off from the first fixing member 51 when the first fixing member 51 pulls the second traction rope 443. The inner wall of the second anti-dropping member 512 is provided with a slope, so that when the protective cover 4 moves outward, the second traction rope 443 can fall off from the first fixing member 51 through the slope of the second anti-dropping member 512.

[0066] In this embodiment, when the user needs to install the terminal body 2 on the aluminum alloy cable 1, the user only needs to insert the wire core 11 on the aluminum alloy cable 1 into the connector 20 on the terminal body 2. Since the liquid capsule 31 is provided on the outside of the wire core 11, when the wire core 11 is inserted into the connector 20, the liquid capsule 31 will also be adaptively sleeved on the insulating sleeve 21 on the outside of the connector 20.

[0067] Then the user only needs to align the corresponding positioning marks on the mounting ring 32 and the fixing ring 22, and insert the mounting piece 321 on the mounting ring 32 into the silicone pleated cavity 221 in the fixing ring 22. This not only enables the installation of the connector 20 and the liquid capsule 31, but also ensures that when the insulating sleeve 21 is assembled in the liquid capsule 31, the limiting groove 211 on the insulating sleeve 21 can be adapted and aligned with the elastic capsule 312 on the liquid capsule 31.

[0068] Then the user only needs to push the push ring 3 toward the liquid bag 31. When the push ring 3 moves to the card slot 14, the movable clamping member 341 in the movable cavity 34 on the push ring 3 can be pushed into the card slot 14 by the thrust of the spring 344, so that the push ring 3 can be fixed by the clamping device between the movable clamping member 341 and the card slot 14.

[0069] During the pushing process of the push ring 3, the liquid on one side of the liquid capsule 31 can be pushed to the other side. As a result, the liquid capsule 31 outside the insulating sleeve 21 can strengthen the wrapping force of the insulating sleeve 21 due to the inflow of more liquid, and more liquid can bulge the elastic capsule 312 outward, so that the elastic capsule 312 that is pushed out can be adapted to be clamped in the limiting groove 211 on the insulating sleeve 21. In this way, the insulating sleeve 21 can be fixedly wrapped in the liquid capsule 31 by the arrangement of the liquid capsule 31 and the elastic capsule 312, thereby improving the connection stability between the wire core 11 and the connector 20.

[0070] Then the user only needs to pull the protective sleeve 4 toward the fixing ring 22. When the protective sleeve 4 moves to the outside of the fixing ring 22, the elastic clamping piece 43 on the protective sleeve 4 can be automatically clamped into the clamping cavity 222 on the fixing ring 22, so as to achieve the adaptive connection between the protective sleeve 4 and the fixing ring 22. In this way, not only can the protective sleeve 4 be used to protect the liquid capsule 31, but also the setting of the protective sleeve 4 can further enhance the connection stability between the wire core 11 and the connector 20.

[0071] Since the rotating ring 5 is provided on the fixed ring 22 and the rotating ring 5 is in a tightened state, when the protective cover 4 is installed, the first fixing member 51 on the rotating ring 5 is located in the upper cavity 441 of the fixing seat 44 and on one side of the second traction rope 443. The adjusting column 54 in the second fixing member 52 on the rotating ring 5 is located in the adjusting groove 352 in the adjusting member 351.

[0072] It is worth noting that since both sides of the bottom of the adjustment column 54 are sloped surfaces, the end of the protective sleeve 4 is provided with a large chamfer, and the adjustment column 54 can be located in the through hole 53 and move, so that the adjustment column 54 will not affect the movement of the protective sleeve 4. When the protective sleeve 4 is assembled, the adjustment column 54 is located outside the adjustment cavity 42. At this time, since the bottom of the adjustment column 54 and the inner wall of the adjustment groove 352 are both magnetic materials that are adapted to attract each other, the adjustment column 54 can automatically move into the adjustment groove 352 through magnetic attraction.

[0073] Furthermore, when the user needs to separate the wire core 11 and the connector 20, the user only needs to rotate the rotating ring 5 on the fixed ring 22 through the external thread 223 and the internal thread groove 56, thereby driving the first fixing member 51 and the second fixing member 52 on the rotating ring 5 to rotate synchronously with the rotating ring 5.

[0074] When the first fixing member 51 rotates, the second traction rope 443 in the upper cavity 441 can be pulled outward, so that the elastic clamping member 43 in the clamping cavity 222 can be pulled outward by the second traction rope 443, and the clamping device between the elastic clamping member 43 and the clamping cavity 222 can be released.

[0075] When the second fixing member 52 rotates, the adjusting column 54 on the second fixing member 52 will rotate synchronously, and the adjusting member 351 can be driven to move in the auxiliary cavity 35 by the rotation of the adjusting column 54. Thus, the first traction rope 345 can be pulled by the movement of the adjusting member 351, so that the movable clamping member 341 can be pulled back from the clamping slot 14 to the movable cavity 34 by the first traction rope 345, and the clamping between the movable clamping member 341 and the clamping slot 14 can be released.

[0076] At this time, since the clamping between the elastic clamp 43 and the clamping cavity 222 and the clamping between the movable clamp 341 and the clamping slot 14 are both released, the user can pull the push ring 3 and the protective sleeve 4 backward synchronously, so that the half-compressed liquid capsule 31 can be reset. At this time, the elastic capsule 312 can be reset by its own elastic force, so that the fixed sleeve of the liquid capsule 31 on the insulating sleeve 21 can be released. The user only needs to pull the mounting member 321 out of the silicone pleated cavity 221 with force, so as to achieve the separation of the wire core 11 and the connector 20. It is also worth noting that after the user has separated the wire core 11 and the connector 20, it is necessary to retighten the movable ring 5 on the fixed ring 22 to achieve the reset of the first fixing member 51 and the second fixing member 52.

[0077] It is worth noting that since both sides of the bottom of the adjustment column 54 are sloped, the side walls of the adjustment groove 352 are also sloped, and a large chamfer is also provided on the adjustment cavity 42. Therefore, when the protective cover 4 moves backward, the adjustment column 54 on the second fixing member 52 can automatically move to the outside of the protective cover 4 through the slope, so that the adjustment column 54 will not affect the protective cover 4 when the protective cover 4 is installed or removed.

[0078] And because the second anti-dropping member 512 is provided with a slope, when the protective cover 4 is pulled backward, the second traction rope 443 can fall off from the first fixing member 51 through the slope of the second anti-dropping member 512. At this time, the second traction rope 443 is no longer pulled by the first fixing member 51, and the elastic clamp 43 can automatically reset by elastic force, thereby driving the second traction rope 443 to reset synchronously.

[0079] In the present invention, by sleeve-arranging the liquid capsule 31 on the outside of the insulating sleeve 21, and cooperating with the clamping arrangement between the elastic clamp 43 and the clamping cavity 222, and the clamping arrangement between the movable clamp 341 and the clamping slot 14, the fixed installation between the wire core 11 and the connector 20 can be achieved, and the liquid capsule 31 can be protected by cooperating with the setting of the protective sleeve 4. This connection method is not only quick and convenient, but also has a better protective structure for the connection between the wire core and the terminal body 2.

[0080] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
